Description

Technical Field

[0001] This utility model relates to the field of anti-twist steel wire rope winding and unwinding technology, specifically an anti-twist steel wire rope winding and unwinding device. Background Technology

[0002] The anti-torsion properties of anti-torsion wire rope are mainly due to its unique manufacturing process. It is usually woven from single-strand round wire ropes with left-hand and right-hand twists in a regular pattern, with the number of left-hand and right-hand twists being equal and symmetrically distributed.

[0003] During the winding and unwinding of wire ropes, twisting often occurs due to insufficient tightening, leading to loosening and reduced service life. Furthermore, when hoisting objects, the suspended objects may rotate; directly connecting the object to the wire rope in this situation can cause the rope to twist, resulting in further loosening. Utility Model Content

[0004] The purpose of this invention is to provide an anti-twist steel wire rope winding and unwinding device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a mounting frame, in which a winding reel is rotatably connected, and a winding motor for driving the winding reel to rotate is fixed on the outside. A guide frame is fixed at the upper end of the mounting frame, and a track rod is fixed inside the guide frame. A sliding frame is slidably connected to the track rod, and a guide roller is rotatably connected to the sliding frame. A steel wire rope is wound around the winding reel, and the end of the steel wire rope is provided with a loading head with a torsion buffer structure.

[0006] Preferably, the mounting frame has a top plate at the bottom, a limit groove is provided on the top plate, a telescopic cylinder is fixed at the bottom of the mounting frame, and the output end of the telescopic cylinder is fixed at the bottom of the top plate. Guide rods are fixed on both sides of the bottom of the top plate, and the bottom of the guide rods are slidably connected inside the mounting frame.

[0007] Preferably, the loading head consists of a fixed plate and a rotating plate. The fixed plate is fixed to the end of the wire rope, and the rotating plate is rotatably connected to the bottom periphery of the fixed plate. A pair of upright plates are fixed to the upper end of the rotating plate, and an arc-shaped rod is fixed to the upright plate. An outer extension plate is fixed to the upper end of the fixed plate.

[0008] Preferably, a high-pressure chamber is provided on the side wall of the extension plate at a position corresponding to the arc-shaped rod. The high-pressure chamber has an arc structure and a piston plate is slidably connected inside. The end of the arc-shaped rod is located inside the high-pressure chamber and is fixedly connected to the piston plate.

[0009] Preferably, a reciprocating lead screw is rotatably connected inside the guide frame, the reciprocating lead screw passes through the sliding frame and is threadedly connected to the sliding frame, and a servo motor for driving the reciprocating lead screw to rotate is fixed on the outside of the guide frame.

[0010] Preferably, a controller is fixed to the front side of the mounting bracket, a magnetoelectric torsion sensor is fixed on the sliding bracket, and the steel wire rope passes through the magnetoelectric torsion sensor.

[0011] Compared with the prior art, the beneficial effects of this utility model are: by using the reciprocating sliding of the guide roller and the winding limit of the limiting groove, the wire rope can be tightly compressed during winding, reducing the risk of twisting and loosening. Furthermore, by using the rotation of the rotating plate and the compression buffer of the piston plate, the impact of the suspended rotation of the hoisted object on the wire rope can be reduced, further reducing the risk of twisting of the wire rope.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4This utility model provides a technical solution: including a mounting frame 1, a winding reel 11 rotatably connected inside the mounting frame 1, and a winding motor 12 for driving the winding reel 11 to rotate fixed on the outside. A guide frame 3 is fixed at the upper end of the mounting frame 1, a track rod 31 is fixed inside the guide frame 3, a sliding frame 4 is slidably connected to the track rod 31, a guide roller 41 is rotatably connected to the sliding frame 4, a steel wire rope is wound on the winding reel 11, and a loading head 6 with a torsion buffer structure is provided at the end of the steel wire rope. A controller 2 is fixed at the front of the mounting frame 1, and a magnetoelectric torsion sensor 42 is fixed on the sliding frame 4. The steel wire rope passes through the magnetoelectric torsion sensor 42.

[0019] The mounting frame 1 has a top plate 5 at its bottom, and a limit groove 51 is provided on the top plate 5. A telescopic cylinder 53 is fixed at the bottom of the mounting frame 1, and the output end of the telescopic cylinder 53 is fixed at the bottom of the top plate 5. Guide rods 52 are fixed on both sides of the bottom of the top plate 5. The bottom of the guide rods 52 is slidably connected to the mounting frame 1. A reciprocating screw 32 is rotatably connected inside the guide frame 3. The reciprocating screw 32 passes through the sliding frame 4 and is threadedly connected to the sliding frame 4. A servo motor 33 that drives the reciprocating screw 32 to rotate is fixed on the outside of the guide frame 3.

[0020] The loading head 6 consists of a fixed plate 61 and a rotating plate 62. The fixed plate 61 is fixed to the end of the wire rope, and the rotating plate 62 is rotatably connected to the bottom periphery of the fixed plate 61. A pair of upright plates 63 are fixed to the upper end of the rotating plate 62, and an arc-shaped rod 64 is fixed on the upright plate 63. An outer extension plate 65 is fixed to the upper end of the fixed plate 61. A high-pressure chamber is opened on the side wall of the outer extension plate 65 at a position corresponding to the arc-shaped rod 64. The high-pressure chamber has a circular arc structure, and a piston plate 66 is slidably connected inside. The end of the arc-shaped rod 64 is located inside the high-pressure chamber and is fixedly connected to the piston plate 66.

[0021] Working principle: First, the entire device is connected to an external power source. The rotation of the output end of the winding motor 12 drives the winding reel 11 to rotate, thereby achieving the purpose of winding and unwinding the wire rope. During this process, the wound wire rope passes through the guide roller 41, and the guide roller 41 slides on the sliding frame 4, thus neatly winding the wire rope onto the winding reel 11. During this process, the drive of the output end of the servo motor 33 drives the reciprocating screw 32 to rotate, thereby driving the sliding frame 4 to slide. Next, the telescopic cylinder 53 drives the top plate 5 to move upward, so that its upper end moves to the contact position with the outermost wire rope, which can tighten the wire rope. The limiting groove 51 can be used to tighten the steel wire rope of adjacent turns, preventing the steel wire rope from becoming tangled and loose on the winding reel 11. Secondly, when lifting items, the rotation of the suspended items will drive the rotating plate 62 to rotate. At this time, the rotation of the rotating plate 62 will drive the arc rod 64 to move into the high-pressure chamber, pushing the piston plate 66 to continuously compress the gas in the high-pressure chamber, achieving the purpose of buffering and reducing the risk of steel wire rope twisting due to the rotation of the items. Throughout the process, the steel wire rope passes through the magnetoelectric torsion sensor 42. It uses the principle of magnetoelectric induction. When the steel wire rope is subjected to torque, the torsion angle of the elastic shaft will change the magnetic resistance of the magnetic circuit, thereby causing the induced electromotive force of the coil to change. By detecting the change in electromotive force, the torque is calculated, and torsion monitoring is performed in real time to ensure operational safety.
