Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of steel pipe sealing test, and in particular to a steel pipe storage rack. Background Technology
[0002] After the welded steel pipes are produced, a water injection test is required to test their sealing and strength. Before testing, the steel pipes are stacked. After stacking, the steel pipes are secured with ropes and placed on a steel pipe storage rack by an overhead crane. The steel pipes on the storage rack are then transported sequentially to the testing device.
[0003] like Figure 1 As shown, this is a steel pipe storage rack, which includes a supporting beam 1 and legs 11. The legs 11 are fixed to the bottom of the supporting beam 1. A baffle 12 is fixed to one end of the supporting beam 1, and a stop block 13 is fixed to the side of the supporting beam 1 away from the baffle 12. The overhead crane lifts a bundle of steel pipes onto the steel pipe storage rack. After that, the workers remove the rope loops. After removal, the steel pipes are instantly laid flat on the beam. If the workers are not careful, the steel pipes may slip and cause injury to the workers. Utility Model Content
[0004] In order to solve the problems existing in the prior art, the present invention provides a steel pipe storage rack.
[0005] This utility model provides a steel pipe storage rack, which adopts the following technical solution:
[0006] A steel pipe storage rack includes multiple spaced and parallel supporting beams. Support legs are fixed to the bottom of each supporting beam. A baffle is fixed to one end of each supporting beam, and a stop block is fixed to the other end. The top surface of the supporting beam is inclined, with the side of the top surface near the baffle higher and the side away from the baffle lower. An inclined block is fixed to the side of the baffle near the stop block. A limit rod is provided on the side wall of the supporting beam. A first rotating shaft is fixed to the supporting beam, and the limit rod is rotatably connected to the first rotating shaft. A hydraulic cylinder is fixed to the support leg to drive the limit rod to rotate along the first rotating shaft. When the piston rod of the hydraulic cylinder retracts, the limit rod is inclined, with its top positioned above the supporting beam, and the limit rod and the inclined block forming a V-shaped groove.
[0007] Optionally, a rubber plate is fixed to the top of the supporting beam.
[0008] Optionally, the support beam is equipped with a toggle assembly capable of moving the steel pipe toward the stop.
[0009] Optionally, the toggle assembly includes a toggle turntable and a toggle lever. A connecting block is fixed to the bottom of the support beam, and a second rotating shaft is rotatably connected to the connecting block. The second rotating shaft is rotatably connected to the toggle turntable, and a motor for driving the second rotating shaft is fixed to the connecting block.
[0010] Compared with the prior art, the present invention has the following technical effects:
[0011] When a bundle of steel pipes is placed on the support beam, the piston rod of the hydraulic cylinder retracts, and the limit rod is tilted, with its top higher than the support beam. The limit rod and the tilting block form a V-shaped groove. The steel pipe is placed between the limit rod and the tilting block. After the worker removes the rope loop from the steel pipe, the worker moves away from the steel pipe and starts the hydraulic cylinder. The piston rod of the hydraulic cylinder extends, thereby driving the limit rod to rotate. The limit rod rotates to below the support beam, and the bundle of steel pipes slides onto the support beam, thus reducing the possibility of injury to the worker. Attached Figure Description

[0016] The following is in conjunction with the appendix Figure 2 - Appendix Figure 3 The present invention will be described in further detail below.
[0017] Reference Figure 2 and Figure 3 This utility model discloses a steel pipe storage rack, including three supporting beams 1, which are spaced apart and parallel to each other. Multiple legs 11 are fixed to the bottom of each supporting beam 1, and a baffle 12 is fixed to one side of each supporting beam 1, connecting the three supporting beams 1 into a single unit. A stop block 13 is fixed to the side of each supporting beam 1 away from the baffle 12, preventing the steel pipes from falling off the supporting beam 1. Inclined blocks 14 are fixed to the side of each baffle 12 near the stop block 13, with the bottom of the inclined blocks 14 fixed to the supporting beam 1. The top surface of each supporting beam 1 is inclined, with the side of the top surface near the inclined block 14 being higher and the side near the stop block 13 being lower.
[0018] Limiting rods 2 are installed on both sides of the supporting crossbeam 1. A first rotating shaft 21 is fixed on the supporting crossbeam 1, and the limiting rods 2 are rotatably connected to the first rotating shaft 21. A hydraulic cylinder 22 is installed below the supporting crossbeam 1. The piston rod of the hydraulic cylinder 22 is hinged to the bottom of the limiting rod 2, and the tail of the hydraulic cylinder 22 is hinged to one of the support legs 11. When the crane lifts the steel pipe onto the supporting crossbeam 1, the piston rod of the hydraulic cylinder 22 retracts, the limiting rod 2 is tilted, and the top of the limiting rod 2 is higher than the supporting crossbeam 1. The limiting rod 2 and the tilting block 14 form a V-shaped groove, placing the steel pipe between the limiting rod 2 and the tilting block 14. Then, the workers remove the rope from the steel pipe. After removing the rope, the hydraulic cylinder 22 is activated, and the hydraulic cylinder drives the limiting rod 2 to rotate, causing the limiting rod 2 to rotate below the supporting crossbeam 1. The steel pipe slides down and lies flat on the supporting crossbeam 1.
[0019] After the limit rod 2 rotates to a horizontal position, the steel pipe will quickly move towards the stop block 13. To reduce the speed of the steel pipe, a toggle assembly 3 is provided between the stop block 13 and the limit rod 2. The toggle assembly 3 includes a toggle turntable 31 and toggle rods 32. A connecting block 33 is fixed to the bottom of the supporting beam 1. A second rotating shaft 34 is rotatably connected to the connecting block 33. The second rotating shaft 34 is rotatably connected to the toggle turntable 31. A motor 35 that drives the second rotating shaft 34 to rotate is fixed to the connecting block 33. Multiple toggle rods 32 are evenly distributed along the circumference of the toggle turntable 31 and are fixedly connected to the toggle turntable 31. The motor 35 drives the second rotating shaft 34 and the toggle turntable 31 to rotate at a uniform speed, so that the sliding steel pipes pass through the position of the toggle turntable 31 one by one evenly, thereby reducing the sliding speed of the steel pipes, reducing the impact force of the steel pipes, and providing a certain degree of protection for the steel pipes.
[0020] A rubber plate 4 is fixed on the top surface of the supporting beam 1. The side of the rubber plate 4 closer to the inclined block 14 is higher, and the side of the rubber plate 4 closer to the stop block 13 is lower. When the limit rod 2 rotates to the horizontal position, the steel pipe slides onto the rubber plate 4, which avoids direct collision between the steel pipe and the supporting beam 1 and protects the steel pipe.
[0021] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
