Here is the content list:
l What are the operational safety requirements for tank hydraulic jacking system?
l What is the safety device of the tank hydraulic jacking system?
l Specific operating rules for tank hydraulic jacking system.
1. Tank hydraulic jacking system drivers and signal personnel must be specially trained
2. Pay attention to whether the tower type learned by the tank hydraulic jacking system driver is consistent with the actual tower type
3. Implement a dedicated person and plane to manage tank hydraulic jacking system, captain responsibility system, and strict handover system
4. The newly installed tank hydraulic jacking system or the tank hydraulic jacking system after overhaul must be commissioned according to the instructions.
5. Keep a safe distance between tank hydraulic jacking system and overhead transmission lines
6. Applicable fire extinguishing equipment should be equipped in the driver's cabin of tank hydraulic jacking system
The installation of tank hydraulic jacking system shall not use aluminum conductor and screw steel as grounding body or underground grounding wire. The wires connected by bolts must have one end. There are three main ways to ground:
① The grounding body adopts regular grounding piles, or 33*4.5 long 1.5m steel pipe, or 70*70 long 1.5m angle steel.
② The grounding plate is made of steel plate or other ductile metal plate, with an area of 1 square meter and a depth of 1.5m from the ground.
③ Copper conductors with a cross-section of not less than 28 mm or steel conductors with a cross-section of not less than 50 mm are buried in the wire slot, and the buried length is determined by the grounding resistance.
In the above three methods, the cross-sectional area of the copper wire drawn from the grounding body should not be less than 25. If the soil is poorly conductive, sodium chloride (table salt) can be buried in the soil. Then fill it with water. For the tank hydraulic jacking system, each rail must be grounded, the two rails should be connected by a wire, and the two rails should also be electrically connected.
l About tank hydraulic jacking system safety device:
1. A safety device that prevents the sling on the hook from slipping off automatically.
2. Install a compression spring sheet at the opening of the hook head to close the opening. This spring sheet can only be pressed down and cannot be turned up after the sling is put in. It can prevent the sling of the tank hydraulic jacking system from falling off automatically.
3. Drum safety device: An effective measure to prevent accidents caused by improper winding of the steel wire rope beyond the drum.
4. A steel bar is welded outside the drum to restrict the wire rope to only move within the drum.
5. Fixed foundation: The digging trench is 600mm deep, concrete is poured on the lime soil, the surface is smooth, and there are waterproof and grounding protection measures.
Before use, check that the metal structural parts and appearance are in good condition, the sound is normal when running under no load, the brake is reliable in the heavy load test, the safety limit and protection devices are complete, and the action is sensitive and reliable before operation.
When operating each controller, it should be operated step by step, and it is strictly forbidden to operate over gear. When changing the direction of rotation, the operating handle should be reset to zero, and the motor should stop rotating before reversing the operation. Strive for stability, and it is strictly forbidden to start and stop.
During the operation of the tank hydraulic jacking system, if any abnormality of the machinery is found, it should be shut down immediately for inspection, and operation can only be carried out after the fault is eliminated.
It is strictly forbidden to work with a certificate, and it is strictly forbidden to work after drinking. It is strictly forbidden to use the travel switch to replace the parking operation. It is strictly forbidden to work in violation of regulations, leave the work post or give the machine to others to drive.
When loading heavy objects, you should leave the ground at a certain distance and check that the brake is reliable before proceeding.Insist on "ten" not hanging. After the operation is completed, the box should be powered off and the machine should be "crossed"!
The installation of pipeline construction equipment is one of the necessary parts in the pipe construction solution, and the installation and construction of pipeline construction equipment is a very important stage in project construction. Due to various factors in the project construction, there are many problems in the installation of pipeline construction equipment. To promote the improvement of the quality of industrial pipeline installation, certain measures need to be taken to control the installation quality of pipeline construction equipment to ensure the smooth construction of the project.
Here is the content list:
l Regarding the quality inspection of pipeline construction equipment installation.
l What are the quality control measures in the installation of pipeline construction equipment?
l Regarding the quality control of pipeline construction equipment after construction.
The sequence of installation of pipeline construction equipment is:
Measuring arrangement→cleaning the construction work area; construction road→conveying anticorrosion pipe→processing tank→distributing pipe→preparing nozzle; pipeline assembly→pipe assembly and welding→welding joint inspection→heat shrinkable casing (tape) bushing→ trench excavation →Appearance repair .
After the installation of pipeline construction equipment is completed, quality inspection is required. After pipeline construction equipment is installed and put into use, regular monitoring is required. Generally, radiographic inspection is used to inspect the quality of pipeline installation. This monitoring has a very good effect on the internal inspection of welded joints. It is widely used in the field of construction equipment installation. This method can also be used to make the quality of the pipeline meet the assessment standard.
Before installing pipeline construction equipment, clarify the construction plan of the construction technicians, use GB/T as the standard, and carry out construction in accordance with national standards and specifications; during the installation of pipeline construction equipment, strictly review the drawings for defects to ensure the rationality of the drawings, and the construction unit It is also necessary to make preparations for pipeline installation and construction, pipeline lumber, welding inspection, construction site management, etc.
Strictly follow the relevant requirements of pipeline construction equipment and pipeline construction requirements to improve the quality of construction. In order to ensure the quality of pipeline installation, quality control is required for key parts such as welding materials, welding processes, and welding seams to ensure pipeline construction equipment. Welding consumables, brands, specifications, etc. are required by the plan design, which are consistent with the project construction requirements to ensure the quality of installation.
① After the pipes, accessories and raw materials used for pipeline construction equipment enter the construction site, the supervisors shall check and accept them on site, and store the materials after passing the acceptance.
② Pipe joints and semi-finished products of pipeline construction equipment should be guaranteed not to be damaged during transportation and storage. When unloading, handle with care and not collide with each other; choose a flat place for stacking pipe joints.
③ The storage temperature of the rubber ring of pipeline construction equipment is between -5 and 30 degrees Celsius. It should not be exposed to ultraviolet light source and keep away from the heat source; the rubber ring and the items that easily affect the rubber ring should not be put together. If the pipeline construction equipment is being constructed In winter, hard rubber rings are not allowed.
④ For trench excavation in open-cut pipeline engineering, the section should meet the design requirements of construction quality, the original soil at the bottom of the trench should not be damaged, and the mechanical excavation should reserve a 200-300mm soil layer for manual excavation and leveling, and the bottom of the trench can be soaked by water And frost damage, if there is gravel soil, lime soil to backfill, the trench wall should be leveled to meet the requirements of construction design.
⑤ For concrete construction, when the pipe seat and flat foundation are poured in layers, the flat foundation should be shaved and rinsed; the concrete should be prevented from segregation, and the concrete should be cured after pouring.
⑥ When pipeline construction equipment is installed, visual inspection and internal cleanliness of the pipeline must be inspected.
⑦ The flexibility of pipe joints must meet the design requirements, and the rigidity must also meet the requirements.
⑧ In the stage of backfilling, the backfill height between both sides of the pipe and the top of the pipe before the hydraulic test of the pressure pipeline is greater than 0.5M, and the pressure-free pipeline shall be backfilled after the closed water test and the closed gas test have reached the standard.
After the completion of the pipeline construction equipment, the finishing work will begin. The unit needs to organize personnel to review the material documents involved in the pipeline installation, project reports, etc.; after the completion of the project, debugging and quality appraisal are required, and the pipeline professionals are organized to conduct quality appraisal of the installed pipelines. The dynamic control of the links will protect the completed pipelines.
In the later stage of the installation of pipeline construction equipment, in order to ensure the smooth completion of the project, the quality of the pipeline needs to be tested again to ensure that the pipeline installation does not have problems such as tilt and cracks, the welding parts are of good quality, and the pipeline is unobstructed. In the later period after the completion of the project, it is necessary to sort out each project data and work files involved in the pipeline construction, do a good job of archiving and backup to evaluate the quality of the pipeline, do a good job in risk control, and carry out the acceptance of pipeline construction equipment.
There are many influencing factors in the installation of pipeline construction equipmentt, so reasonable measures need to be taken to monitor and control every aspect of pipeline construction equipment. With the continuous expansion of the pipeline construction equipment construction industry, the use area is also expanding. Due to the importance of pipeline use, it is necessary to control the pipeline installation quality to ensure that the installation quality reaches the ideal standard!
