Description

Technical Field

[0001] This utility model relates to the technical field of wire rope winding and unwinding equipment, and specifically discloses a device for preventing wire rope from jumping off the groove. Background Technology

[0002] In various lifting, transportation, and traction equipment, wire ropes are key force-transmitting components, and their stable operation directly affects the safety and efficiency of the equipment. However, in practical applications, wire ropes often deviate from their preset running trajectory due to problems such as equipment vibration, deviation in running trajectory, or improper initial installation position, resulting in a "slippage" phenomenon.

[0003] During hoisting operations, the lack of wire rope restraints and excessive release during wire rope deployment can lead to wire rope derailment, tangling, and jamming, preventing the wire rope from reaching its normal service life and causing abnormal wear. This shortens the lifespan of the wire rope and reduces the normal operating rate of the hoisting equipment. Therefore, a wire rope anti-derailment device is needed to solve this problem. Utility Model Content

[0004] This invention proposes a wire rope anti-slip device, which achieves stable control of the wire rope through a first guide structure and a second guide structure in multiple stages, significantly reducing the incidence of slippage accidents.

[0005] This utility model is implemented as follows: a wire rope anti-slip device includes a fixing buckle, the front end face of which is provided with a first guide structure, and a second guide structure is provided in front of the first guide structure.

[0006] The first guide structure includes two mounting plates symmetrically fixed to the front end face of the fixed buckle via a connecting rod, mounting seats fixedly connected to opposite sides of the two mounting plates, guide wheels rotatably connected to the interior of the two mounting seats via a rotating shaft, and guide grooves formed on the outer wall of the guide wheels;

[0007] The second guide mechanism includes two vertical plates symmetrically fixed to the front end faces of two mounting plates, a threaded rod that passes through and is threadedly connected to the outer wall of the two vertical plates, and an arc-shaped stop block that is rotatably connected to one end of the threaded rod via a bearing.

[0008] As a preferred embodiment of the wire rope anti-slip device of this utility model, the fixing buckle has a triangular structure.

[0009] As a preferred embodiment of the wire rope anti-slip device of this utility model, rubber pads are provided on the opposite sides of the two arc-shaped blocks.

[0010] As a preferred embodiment of the wire rope anti-slip device of this utility model, the inner wall of the fixing buckle is provided with a wear-resistant pad.

[0011] As a preferred embodiment of the wire rope anti-slip device of this utility model, a handwheel is fixedly connected to the other end of the threaded rod.

[0012] The beneficial effects of this utility model are:

[0013] The wire rope is initially limited and coarsely adjusted by the second guide structure, which can effectively prevent the wire rope from swinging significantly in the initial stage. Then, the wire rope is precisely guided and constrained by the guide wheel in the first guide structure, which can ensure that the wire rope always runs on the preset track. The combination of the two achieves stable control of the wire rope from multiple stages, which greatly reduces the incidence of slippage accidents. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0020] Please see Figure 1-3 A wire rope anti-slip device includes a fixing buckle 1, a first guide structure is provided on the front end face of the fixing buckle 1, and a second guide structure is provided in front of the first guide structure.

[0021] The first guide structure includes two mounting plates 2 symmetrically fixed to the front end face of the fixed buckle 1 via connecting rods, mounting bases 201 fixedly connected to opposite sides of the two mounting plates 2, guide wheels 202 rotatably connected to the inside of the two mounting bases 201 via rotating shafts, and guide grooves 203 formed on the outer wall of the guide wheels 202.

[0022] The second guide structure includes two vertical plates 3 symmetrically fixed to the front end faces of two mounting plates 2, a threaded rod 301 that passes through and is threadedly connected to the outer wall of the two vertical plates 3, and an arc-shaped stop 302 that is rotatably connected to one end of the threaded rod 301 via a bearing.

[0023] In this embodiment: the wire rope first passes through the second guide structure composed of two arc-shaped stops 302, and rotates the threaded rod 301, causing the threaded rod 301 to push the two arc-shaped stops 302 closer to each other until the two arc-shaped stops 302 limit the wire rope. Then it is embedded in the guide groove 203 on the guide wheel 202, and then passes through the fixing buckle 1. The second guide structure plays a role in initial limiting and coarse adjustment, preventing the wire rope from swaying significantly in the initial stage. The first guide structure precisely guides and constrains the wire rope through the freely rotating guide wheel 202, ensuring that it always runs on the preset trajectory. The combination of the two achieves stable control of the wire rope from multiple stages, greatly reducing the incidence of slippage accidents. The design of the guide wheel 202 changes sliding friction to rolling friction, which greatly reduces the wear of the wire rope.

[0024] As a technical optimization of this utility model, the fixing buckle 1 has a triangular structure.

[0025] In this embodiment: by fixing the buckle 1 in a triangular structure, the wire rope can be limited to the center of the triangle.

[0026] As a technical optimization of this utility model, rubber pads are provided on the opposite sides of the two arc-shaped blocks 302.

[0027] In this embodiment, the elastic cushioning effect of the rubber pad can absorb the slight vibration and impact of the wire rope, while ensuring that the arc-shaped stop 302 will not scratch or wear the wire rope when it comes into contact with the wire rope surface, thus protecting the wire rope.

[0028] As a technical optimization of this utility model, the inner wall of the fixing buckle 1 is provided with a wear-resistant pad.

[0029] In this embodiment, the wear-resistant pad effectively reduces frictional wear between the fixing buckle 1 and the center of the fixing buckle 1.

[0030] As a technical optimization of this utility model, a handwheel is fixedly connected to the other end of the threaded rod 301.

[0031] In this embodiment: the threaded rod 301 can be rotated by holding the handwheel.

[0032] The working principle and usage process of this utility model are as follows: First, the wire rope is threaded through the second guide structure composed of two arc-shaped stops 302. The operator rotates the threaded rod 301, pushing the two arc-shaped stops 302 closer together until they are exactly in contact with the outer wall of the wire rope, thus achieving initial positioning of the wire rope. During this process, the rubber pads on opposite sides of the arc-shaped stops 302 are in direct contact with the wire rope. The elastic cushioning effect of the rubber pads absorbs any slight vibrations and impacts that may occur in the wire rope at this time.

[0033] After initial positioning, the wire rope continues to extend forward and embeds itself into the guide groove 203 of the guide wheel 202 in the first guide structure. When the wire rope moves, it drives the guide wheel 202 to rotate synchronously. At this time, the friction between the wire rope and the guide wheel 202 changes from sliding friction to rolling friction. Simultaneously, the shape of the guide groove 203 is adapted to the wire rope, enabling precise guidance and constraint of the wire rope, ensuring its stable operation along the preset trajectory.

[0034] Subsequently, the wire rope passes through the fixing buckle 1, where it is naturally confined at the center of the triangle, further preventing it from tilting. The wear-resistant pad on the inner wall of the fixing buckle 1 directly contacts the wire rope, effectively reducing frictional loss between them and extending the service life of both the device and the wire rope.

[0035] In the description of this utility model, it should be understood that the terms "left", "right", "up", "down", "top", "bottom", "front", "back", "inner", "outer", "back", "middle", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0036] However, the above description is only a specific embodiment of this utility model and should not be construed as limiting the scope of implementation of this utility model. Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
