Description

Technical Field

[0001] The utility model relates to the field of lifting equipment for skid-mounted tanks, and particularly relates to a special sling for lifting skid-mounted tanks. Background Art

[0002] The skid-mounted tank has a unique double-wall tank structure design, excellent barrier explosion-proof materials and advanced production manufacturing processes, ensuring the safe and reliable operation of the tank body in various commonly encountered extreme situations such as violent impact, lightning strike, refueling with fire, electric welding with oil, drilling with oil, and electrostatic sparks.

[0003] Due to the large volume of the skid-mounted tank, it is moved by hoisting when transferring the skid-mounted tank. When using the hoisting equipment, the sling mainly lifts both ends of the skid-mounted tank through the lifting chain. However, when using the lifting chain, in order to facilitate telescoping, the unused part of the lifting chain is wound up, but this is not convenient for inspecting and maintaining the lifting chain. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a special sling for lifting skid-mounted tanks, which can effectively solve the problems in the background art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A special sling for lifting skid-mounted tanks includes a cross beam, upper lifting blocks and lower lifting blocks. The upper surfaces of both ends of the cross beam are fixedly installed with upper lifting blocks, the lower surfaces of both ends of the cross beam are fixedly installed with lower lifting blocks, moving blocks are arranged inside both ends of the cross beam, brackets are movably installed on the side surfaces of the moving blocks, and lifting chains are arranged on the lower lifting blocks.

[0007] Preferably, moving grooves are opened inside both ends of the cross beam, a rotating motor is fixedly installed on the surface of one end of the cross beam, a double-headed threaded rod is fixedly installed at the output end of the rotating motor, the double-headed threaded rod penetrates through the moving grooves, and racks are fixedly installed on the front surface and the rear surface of the cross beam and above one end of the moving grooves.

[0008] Preferably, the bracket includes a U-shaped rod, a gear, a movable rod, a torsion spring and a stop block. Gears are fixedly installed on the outer surfaces of both sides of the upper end of the U-shaped rod, movable rods are fixedly installed on the inner surfaces of both sides of the upper end of the U-shaped rod, and a stop block is fixedly installed on the surface of one end of the movable rod.

[0009] Preferably, threaded holes are opened inside the moving blocks, rod grooves are opened inside both ends of the moving blocks, one end of the movable rod is embedded in the rod grooves, and the moving blocks are sleeved on the surface of the double-headed threaded rod inside the moving grooves.

[0010] Preferably, one end of the torsion spring is fixed to the stop block, and the other end of the torsion spring is fixed to the inner end surface of the rod groove.

[0011] Preferably, the bottom end of the bracket is located below the lower suspension block.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] In the utility model, by setting the cross beam, the bracket and the moving block to cooperate with each other, when the lifting chain is not in use, the rotation motor of the cross beam is started, and the rotation motor controls the double-headed threaded rod to rotate. At this time, the moving block will move towards the middle of the cross beam. When the moving block moves, it will drive the bracket to move. When the bracket moves, it can continuously fold the lifting chain towards the lower part of the middle of the cross beam. When the moving block moves a certain distance, the gear of the bracket will engage with the rack of the cross beam. As the moving block continues to move, the bracket flips under the cooperation of the gear and the rack until the bracket clamps the lifting chain on the lower surface of the cross beam. In this way, the storage of the lifting chain is completed, and it is convenient to check and maintain the lifting chain. Description of the Drawings

Detailed Embodiment

[0019] In order to make the technical means, creative features, achieving purposes and effects of the utility model easy to understand, the utility model will be further described below in conjunction with the specific embodiments.

[0020] Such as Figures 1-4A special lifting tool for skid-mounted tanks is shown, which includes a cross beam 1, an upper lifting block 2 and a lower lifting block 3. The upper lifting blocks 2 are fixedly installed on the upper surfaces of both ends of the cross beam 1, and the lower lifting blocks 3 are fixedly installed on the lower surfaces of both ends of the cross beam 1. Moving blocks 6 are arranged inside both ends of the cross beam 1. Brackets 5 are movably installed on the side surfaces of the moving blocks 6, and lifting chains 4 are arranged on the lower lifting blocks 3.

[0021] Moving grooves 101 are formed inside both ends of the cross beam 1. A rotary motor 102 is fixedly installed on the surface of one end of the cross beam 1. The output end of the rotary motor 102 is fixedly installed with a double-headed threaded rod 103. The double-headed threaded rod 103 penetrates through the moving groove 101. Rack bars 104 are fixedly installed on the front and rear surfaces of the cross beam 1 and above one end of the moving groove 101. The rotary motor 102 can drive the double-headed threaded rod 103 to rotate; The bracket 5 includes a U-shaped rod 501, a gear 502, a movable rod 503, a torsion spring 505 and a stop block 504. Gears 502 are fixedly installed on the outer surfaces of both upper ends of the U-shaped rod 501. Movable rods 503 are fixedly installed on the inner surfaces of both upper ends of the U-shaped rod 501. A stop block 504 is fixedly installed on the surface of one end of the movable rod 503; Threaded holes 601 are formed inside the moving blocks 6. Rod grooves 602 are formed inside both ends of the moving blocks 6. One end of the movable rod 503 is embedded in the rod groove 602. The moving blocks 6 are sleeved on the surface of the double-headed threaded rod 103 inside the moving groove 101. When the moving blocks 6 move, they can drive the brackets 5 to move; One end of the torsion spring 505 is fixed to the stop block 504, and the other end of the torsion spring 505 is fixed to the inner surface of one end of the rod groove 602; The lowermost end of the bracket 5 is located below the lower lifting block 3.

[0022] It should be noted that the present utility model is a special lifting tool for skid-mounted tanks. When in use, when the lifting chain 4 is not used, the rotary motor 102 of the cross beam 1 is started, and the rotary motor 102 controls the double-headed threaded rod 103 to rotate. At this time, the moving blocks 6 will move towards the middle of the cross beam 1. When the moving blocks 6 move, they will drive the brackets 5 to move. When the brackets 5 move, they can continuously fold the lifting chain 4 towards the lower part of the middle of the cross beam 1. The function of the torsion spring 505 can prevent the bracket 5 from being pushed and flipped by the lifting chain 4 during the process of folding the lifting chain 4. When the moving blocks 6 move a certain distance, the gears 502 of the brackets 5 will engage with the rack bars 104 of the cross beam 1. As the moving blocks 6 continue to move, the brackets 5 will flip under the cooperation of the gears 502 and the rack bars 104 until the brackets 5 clamp the lifting chain 4 on the lower surface of the cross beam 1. In this way, the storage of the lifting chain 4 is completed, and it is convenient to check and maintain the lifting chain 4.
