[0020] See also Figure 1-Figure 4 The utility model provides a technical solution: a liftable steel wire rope production and transportation frame, comprising a base plate 1, a fixed plate 2 and a bidirectional threaded rod 3, both sides of the top of the base plate 1 are connected with the fixed plates 2 by fixing bolts, the fixed plates 2 play a fixing role, the bidirectional threaded rod 3 is connected to the middle of the two groups of fixed plates 2 by bearings, the side of the fixed plate 2 away from the bidirectional threaded rod 3 is connected with a forward and reverse motor 4, the output end of the forward and reverse motor 4 is connected to the bidirectional threaded rod 3, and the forward and reverse motor 4 can drive the bidirectional threaded rod 3 to rotate.

[0021] The opposite threaded outer walls on both sides of the bidirectional threaded rod 3 are threadedly connected with moving blocks 5. The helix angle between the moving block 5 and the bidirectional threaded rod 3 is smaller than the equivalent friction angle between the tooth surfaces, and the bidirectional threaded rod 3 has a self-locking characteristic. The rotation of the bidirectional threaded rod 3 can only be converted into axial movement of the moving block 5. The bidirectional threaded rod 3 cannot be driven by any axial force acting on the moving block 5. The threads on the left and right sides of the bidirectional threaded rod 3 are in opposite directions. The rotation of the bidirectional threaded rod 3 can drive the two groups of moving blocks 5 to move in opposite directions to each other. The top ends of the two groups of moving blocks 5 are connected to a scissor frame 6 through a rotating shaft. When the two groups of moving blocks 5 move in relative directions, the scissor frame 6 can be driven to rise or fall. The top of the scissors frame 6 is connected with a slider 7 through a rotating shaft, and a lifting plate 8 is arranged on the top of the slider 7. The raising or lowering of the scissors frame 6 can drive the lifting plate 8 to rise and fall, thereby realizing the adjustment of the height of the transport frame. A slide groove 9 is arranged at the bottom end of the lifting plate 8, and the slider 7 is embedded in the slide groove 9. The slider 7 can move in the slide groove 9, and the slider 7 and the slide groove 9 play a limiting role. Fixed frames 10 are welded on both sides of the top of the lifting plate 8, and the fixed frames 10 play a supporting and fixing role. Limiting rods 23 are arranged on both sides of the top of the base plate 1, and the top of the limiting rod 23 passes through the lifting plate 8. The limiting rod 23 plays a limiting role to improve the stability during lifting and moving.

[0022] The middle part of the fixed frame 10 is connected with a rotating shaft 11 through a bearing. The rotating shaft 11 can rotate in the fixed frame 10. A motor can be installed on one side of the fixed frame 10 to drive the rotating shaft 11 to rotate. A winding drum 12 is sleeved on the outer wall of the middle part of the rotating shaft 11. The rotation of the rotating shaft 11 drives the winding drum 12 to rotate and reel. The winding drum 12 can reel and store the wire rope for subsequent transportation. Electric telescopic rods 13 are connected to both sides of the middle part of the upper surface of the lifting plate 8. The top of the electric telescopic rod 13 is connected to a top plate 14. The top plate 14 is The electric telescopic rod 13 can drive the top plate 14 to move up and down. When the wire rope is wound to the outer wall of the winding drum 12, the electric telescopic rod 13 drives the top plate 14 to lift up and clamp the wound wire rope, thereby preventing the wire rope from loosening after winding and improving the stability of the transport rack during transportation. The upper surface of the top plate 14 is glued with an anti-skid pad 15 by glue. The material of the anti-skid pad 15 is rubber. The anti-skid pad 15 can increase the friction between the wire rope and the top plate 14 to prevent slipping.

[0023] A shock absorbing mechanism 16 is arranged at the bottom end of the bottom plate 1. The shock absorbing mechanism 16 can improve the stability of the transport frame during transportation. The shock absorbing mechanism 16 includes a movable cylinder 17, a rebound column 18, a spring 19, a limit plate 20, and a damping ring 21. The top of the movable cylinder 17 is provided with a rebound column 18. The bottom end of the rebound column 18 is embedded in the movable cylinder 17. The outer wall of the rebound column 18 and the movable cylinder 17 is sleeved with a supporting spring 9. The top of the rebound column 18 and the bottom of the movable cylinder 17 are both connected to the limit plate 20. The top outer wall of the rebound column 18 is sleeved with a damping ring 21. The outer wall of the damping ring 21 abuts against the inner wall of the movable cylinder 17. The material of the damping ring 21 is rubber. When the transport frame encounters bumps during transportation After the road section vibrates, the bottom plate 1 presses down the rebound column 18 and contracts it in the direction of the movable cylinder 17, so that the limit plate 20 squeezes the support spring 19. The support spring 19 contracts under the force and plays a shock-absorbing and buffering role. After the shock absorption, the support spring 19 drives the limit plate 20 to rebound, thereby driving the rebound column 18 to rebound in the opposite direction of the movable cylinder 17. The friction between the damping ring 21 and the inner wall of the rebound column 18 generates a certain resistance to suppress the vibration of the support spring 19 when it rebounds after shock absorption, thereby playing a vibration reduction effect, thereby improving the stability of the transport frame. The bottom end of the shock absorbing mechanism 16 is connected to a universal wheel 22, which facilitates the movement of the transport frame. At the same time, a locking mechanism is arranged inside the universal wheel 22 to facilitate the fixation of the transport frame.

[0024] Working principle: When a liftable wire rope production transport rack is used, the wire rope to be transported is first wound around the outer wall of the winding drum 12 for winding. When the wire rope is wound to the outer wall of the winding drum 12, the electric telescopic rod 13 drives the top plate 14 to lift up and clamp the wound wire rope, thereby preventing the wire rope from loosening after winding and improving the stability of the transport rack during transportation. The anti-skid pad 15 can increase the friction between the wire rope and the top plate 14 to play an anti-skid role. When the transport rack encounters a bumpy road section during transportation, after the vibration, the bottom plate 1 presses down the rebound column 18 to shrink and move toward the direction of the movable cylinder 17, so that the limit plate 20 squeezes the support spring 19, and the support spring 19 shrinks under force to play a shock absorbing and buffering role. After shock absorbing, the support spring 19 drives the limit plate 20 to rebound, thereby driving the rebound column 18 to rebound in the opposite direction of the movable cylinder 17, and a certain resistance is generated by the friction between the damping ring 21 and the inner wall of the rebound column 18 to suppress The control spring 19 absorbs the shock when the support spring rebounds after shock absorption, thereby playing a vibration reduction effect, thereby improving the stability of the transport frame, the bottom end of the shock absorbing mechanism 16 is connected with a universal wheel 22, the universal wheel 22 is convenient for the transport frame to move, and the universal wheel 22 is provided with a locking mechanism inside to facilitate the fixation of the transport frame, the forward and reverse motor 4 can drive the two-way threaded rod 3 to rotate, and the rotation of the two-way threaded rod 3 can drive the two sets of moving blocks 5 to translate in opposite directions to each other, and the scissor frame 6 can be driven to rise or fall when the two sets of moving blocks 5 move in relative directions, and the top of the scissor frame 6 is connected with a slider 7 through a rotating shaft, and a lifting plate 8 is provided on the top of the slider 7. The lifting or lowering of the scissor frame 6 can drive the lifting plate 8 to rise and fall, thereby realizing the adjustment of the height of the transport frame, and after adjusting to the required height, due to the self-locking property of the moving block 5 and the two-way threaded rod 3, the height of the transport frame is kept at the current position and stopped, so that corresponding adjustments can be made according to actual needs.
