[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] Reference Figure 1-4 A sling stabilizing device for a crane includes a mounting frame 1. The mounting frame 1 has a winding mechanism 4 fixedly mounted on its inner wall for winding the rope. A height adjustment mechanism is installed at the bottom of the mounting frame 1 to adjust the height of a roller 8, facilitating sling stabilization via the roller 8. A horizontal adjustment mechanism is installed at the bottom of the height adjustment mechanism to adjust the horizontal position of the roller 8, further facilitating sling stabilization via the roller 8. A first mounting plate 9 is installed at one end of the horizontal adjustment mechanism to support a second mounting plate. The installation of plate 5 involves fixing a second mounting plate 5 onto the first mounting plate 9. The second mounting plate 5 is used to support the installation of the damping spring vibration damper 7. The damping spring vibration damper 7 is fixedly installed on the side of the second mounting plate 5. By setting the damping spring vibration damper 7, it plays a damping role when the roller 8 clamps the rope, reducing the sway amplitude of the rope. A receiving frame 6 is fixedly installed at one end of the damping spring vibration damper 7. The receiving frame 6 is used to support the rotation of the roller 8. The inner wall of the receiving frame 6 is rotatably connected to four rollers 8. The rollers 8 are used to clamp the rope, thereby achieving the purpose of rope stability.
[0021] In detail, the first mounting plate 9 is square in shape and is used to support the installation of the second mounting plate 5. The second mounting plate 5 is square in shape, and there are two of them. The second mounting plate 5 is used to support the installation of the damping spring shock absorber 7.
[0022] Furthermore, there are four damping spring dampers 7. By setting up the damping spring dampers 7, the rope is damped when the roller 8 clamps the rope, reducing the sway amplitude of the rope. The support frame 6 is U-shaped.
[0023] Furthermore, the height adjustment mechanism includes a housing 21, which is fixedly installed at the bottom of the mounting frame 1. The housing 21 is square in shape and has an open bottom. A motor 26 is fixedly installed on the inner wall of the housing 21. The motor 26 has forward and reverse rotation functions. The motor 26 is used to drive the lead screw 25 to rotate. The lead screw 25 is fixedly installed on the shaft end of the motor 26. The lead screw 25 is used to drive the lifting block 22 to move.
[0024] More specifically, a lifting block 22 is threaded onto the lead screw 25. The lifting block 22 is square in shape and is used to support the installation of the box body 31. A limiting groove 24 is provided on the side of the box body 21. The limiting groove 24 is a strip-shaped through hole. A limiting slider 23 is fixedly installed on the side of the lifting block 22. The limiting slider 23 is square in shape and slides on the inner wall of the limiting groove 24. By setting the limiting groove 24 and the limiting slider 23, the movement of the lifting block 22 is limited, which facilitates the vertical movement of the lifting block 22.
[0025] In general, the horizontal adjustment mechanism includes a box body 31, which is fixedly installed at the bottom of the lifting block 22. The box body 31 is square in shape and has openings at both ends. A moving block 33 is slidably installed on the inner wall of the box body 31. A first mounting plate 9 is fixedly installed at one end of the moving block 33. The box body 31 is designed to support the sliding of the moving block 33.
[0026] Finally, a bracket 34 is fixedly installed on the side of the box 31. The bracket 34 is designed to support the installation of the cylinder 32. The bracket 34 is L-shaped. The cylinder 32 is fixedly installed on the side of the bracket 34. The piston rod end of the cylinder 32 passes through the inner wall of the bracket 34 and is fixedly connected to the moving block 33. The cylinder 32 is designed to drive the moving block 33 to slide linearly along the inner wall of the box 31.
[0027] Working principle: During operation, the rope moves up and down between the rollers 8. A damping spring damper 7 dampens the rope as it slides on the surface of the rollers 8, reducing the rope's sway. When the height of the rollers 8 needs adjustment, the motor 26 is started. The motor 26 drives the lead screw 25 to rotate, which in turn moves the lifting block 22. Under the limiting action of the limiting groove 24 and the limiting slider 23, the lifting block 22 moves vertically downwards. During this downward movement, the lifting block 22 drives the rollers 8 downwards through the horizontal adjustment mechanism until the rollers 8 reach the appropriate position, facilitating rope stabilization.
[0028] When it is necessary to adjust the horizontal position of the roller 8, the cylinder 32 can drive the moving block 33 to move. During the movement, the moving block 33 will drive the roller 8 to move horizontally through the first mounting plate 9 and the second mounting plate 5 until the roller 8 moves to the appropriate position, which is conducive to stabilizing the rope.
[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
