Description

Technical Field

[0001] The utility model relates to the technical field of steel wire rope anti-twist devices, in particular to a steel wire rope anti-twist device. Background Art

[0002] When a wire rope is under tension, the spiral elements inside it interact with each other to generate internal forces. These internal forces can be decomposed into an axial component parallel to the axis of the wire rope and a radial component perpendicular to the axis of the wire rope. The radial component causes the rope strands or wire rope to twist. At the same time, when external conditions are unstable, such as changes in the load on the wire rope, the wire rope will also be subjected to torsion.

[0003] The wire rope will be twisted and deformed under the influence of such internal force or external factors, which will wear and damage the wire rope. In severe cases, it will cause the wire rope to become loose and broken, greatly affecting the service life of the wire rope, and posing a great threat to the protection of safe production and personal safety.

[0004] The two ends of the wire rope are connected to the installation body, and torque is easily generated when the wire rope is transmitted. The torque will cause the internal strands of the wire rope to twist and spread, reducing the tensile resistance of the wire rope. Therefore, a wire rope anti-twist device is proposed, which can ensure that the torque along the rotation direction of the wire rope is always applied to the wire rope during transmission, effectively preventing the wire rope from spreading. Utility Model Content

[0005] The utility model aims to provide a steel wire rope anti-twist device, which has the characteristic of applying a torsion force along the rotation direction of the steel wire rope to the steel wire rope.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wire rope anti-twist device, comprising an installation connecting plate and a wire rope main body, the installation connecting plate is provided with a cavity inside, the inner top wall of the cavity is rotatably penetrated by a through shaft, the upper end of the through shaft is provided with a ring frame, the lower end of the wire rope main body is connected by a detachable structure after passing around the inner ring side of the ring frame, one end of the through shaft located inside the cavity is fixedly sleeved with a friction disk, a ring disk is provided inside the cavity, the friction disk is located on the inner ring side of the ring disk, a friction block is slidably inserted into the inner ring surface of the ring disk, a pressure telescopic rod is provided on the side of the friction block away from the friction disk, the other end of the pressure telescopic rod is fixedly connected to the inner wall of the ring disk, a power structure is installed inside the cavity, and the power structure is connected to the ring disk.

[0007] In order to provide power to the ring disk, as a preferred wire rope anti-twisting device of the utility model, the power structure includes a motor, a gear and a gear ring, the gear is fixedly sleeved on the output end of the motor, the motor is installed inside the cavity, the gear is meshed with the gear ring, and the gear ring is installed on the bottom surface of the ring disk.

[0008] In order to facilitate the detachable connection between the wire rope body and the ring frame, as a preferred wire rope anti-twisting device of the utility model, the detachable structure includes two clamping plates, the lower end of the wire rope body is bent and located between the two clamping plates, and the two clamping plates are detachably connected by bolts.

[0009] In order to ensure synchronous rotation of the ring frame and the clamping plate, as a preferred wire rope anti-twisting device of the utility model, a limiting rod can be detachably installed on one side of the two clamping plates away from each other, and the other end of the limiting rod is fixedly connected to the upper surface of the ring frame.

[0010] In order to make the thrust applied by the pressure telescopic rod to the friction block perpendicular to the surface of the friction disk, as a preferred wire rope anti-twisting device of the utility model, the pressure telescopic rod is coaxially arranged with the connected friction block, and the axis of the pressure telescopic rod intersects the axis of the through shaft perpendicularly.

[0011] In order to evenly distribute the friction force on the surface of the friction disk, as a preferred wire rope anti-twist device of the utility model, a plurality of friction blocks are provided, and the plurality of friction blocks are distributed in a circular array around the axis of the friction disk.

[0012] In order to prevent the contact surfaces of the friction block and the friction disc from being uneven as they wear, so that there is always friction between them, a preferred wire rope anti-twist device of the utility model is provided with a plurality of ring-shaped perforations inside the friction disc, and the perforations of each two adjacent rings are staggered, and the bottom surface of the friction block is provided with a plurality of rows of through grooves that pass through the top and bottom, and the adjacent rows of grooves are staggered with each other.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The utility model is provided with components such as a friction disc, a friction block and a pressure telescopic rod. The pressure telescopic rod pushes the friction block to contact the friction disc. When the ring disc rotates, the friction force generated by the pressure applied by the friction block to the friction disc drives the through-shaft to rotate. Then, the ring frame drives the wire rope body to rotate around the direction of the rope strand knob of the wire rope body through the detachable structure. When the wire rope body is loose during transmission, the rotational force of the through-shaft on the wire rope body can drive the rope strands to be wound and tightened, thereby ensuring that the wire rope body will not be loose.

[0015] 2. The utility model provides components such as perforations and grooves. As the friction and rotation wear of the friction disc and the friction block increases, the radius of the friction disc decreases and the length of the friction block decreases. As the radius of the friction disc decreases, the perforations of different rings gradually leak out and contact the friction block. As the length of the friction block decreases, the different staggered grooves leak out and contact the friction disc, ensuring that the friction block and the friction disc will not gradually become smooth as they wear, and the surfaces of the friction block and the friction disc are always in an uneven state.

A through-shaft 2 is rotatably passed through the inner top wall of the cavity 5. A ring frame 4 is installed on the upper end of the through-shaft 2. The lower end of the wire rope body 3 is connected by a detachable structure 7 after passing the inner ring side of the ring frame 4. A friction disc 8 is fixedly sleeved on one end of the through-shaft 2 located inside the cavity 5. A ring disc 9 is arranged inside the cavity 5. The friction disc 8 is located on the inner ring side of the ring disc 9. A friction block 10 is slidably inserted on the inner ring surface of the ring disc 9. A pressure telescopic rod 11 is installed on the side of the friction block 10 away from the friction disc 8. The other end of the pressure telescopic rod 11 is fixedly connected to the inner wall of the ring disc 9. A power structure 6 is installed inside the cavity 5. The power structure 6 is connected to the ring disc 9.

[0025] In this embodiment: when the friction disc 8 rotates, the friction block 10 is driven to rotate through the pressure telescopic rod 11, and the friction disc 8 rotates under the action of the friction force between the friction block 10 and the friction disc 8, and then the ring frame 4 drives the wire rope body 3 to rotate around the rope strand knob direction of the wire rope body 3 through the detachable structure 7 to ensure that the wire rope body 3 will not be scattered.

[0026] As a technical optimization solution of the utility model, the power structure 6 includes an electric motor 61, a gear 63 and a gear ring 62. The gear 63 is fixedly sleeved on the output end of the electric motor 61. The electric motor 61 is installed inside the cavity 5. The gear 63 is meshed with the gear ring 62. The gear ring 62 is installed on the bottom surface of the ring disk 9.

[0027] In this embodiment, the motor 61 drives the gear 63 to rotate, and the gear ring 62 provides rotational power to the ring disk 9 by meshing with the gear 63 .

[0028] As a technical optimization solution of the utility model, the detachable structure 7 includes two clamping plates 71, the lower end of the wire rope body 3 is bent and located between the two clamping plates 71, and the two clamping plates 71 are detachably connected by bolts.

[0029] In this embodiment, the steel wire rope body 3 and the ring frame 4 can be separated by disassembling the two clamping plates 71 .

[0030] As a technical optimization solution of the present invention, a limiting rod 72 can be detachably installed on one side of the two clamping plates 71 away from each other, and the other end of the limiting rod 72 is fixedly connected to the upper surface of the ring frame 4.

[0031] In this embodiment: the ring frame 4 drives the clamping plate 71 to rotate synchronously through the limiting rod 72, and then the clamping plate 71 drives the connected wire rope body 3 to rotate synchronously, ensuring that when the wire rope body 3 tends to be scattered, the ring frame 4 can drive the clamping plate 71 to rotate synchronously in time when it rotates.

[0032] As a technical optimization solution of the utility model, the pressure telescopic rod 11 is coaxially arranged with the connected friction block 10 , and the axis of the pressure telescopic rod 11 intersects the axis of the through shaft 2 at right angles.

[0033] As a technical optimization solution of the present invention, a plurality of friction blocks 10 are provided, and the plurality of friction blocks 10 are distributed in an array around the axis of the friction disk 8 .

The bottom surface of the friction block 10 is provided with a plurality of rows of vertically penetrating grooves 13, and the two adjacent rows of grooves 13 are staggered with each other.

[0036] In this embodiment: as the friction disc 8 and the friction block 10 wear more, the perforations 12 and the grooves 13 at different positions leak out, ensuring that after the friction disc 8 and the friction block 10 are worn, the outer annular surface of the friction disc 8 and the end of the friction block 10 away from the pressure telescopic rod 11 are both uneven, so that there is always friction between the friction disc 8 and the friction block 10.

[0037] Working principle:

[0038] The motor 61 drives the ring disk 9 to rotate through the engagement of the gear 63 and the gear ring 62, and the pressure telescopic rod 11 squeezes the friction disk 8 through the friction block 10. When the ring disk 9 rotates, the friction block 10 is driven to rotate through the pressure telescopic rod 11. The friction disk 8 rotates under the action of the friction force between the friction block 10 and the friction disk 8. When the friction disk 8 rotates, it drives the through shaft 2 to rotate, and then the ring frame 4 drives the wire rope body 3 to rotate around the rope strand knob direction of the wire rope body 3 through the detachable structure 7. When the wire rope body 3 is loose during transmission, the rotational force of the through shaft 2 on the wire rope body 3 can drive its rope strands to be wound and tightened to ensure that the wire rope body 3 will not be loose.
