Description

Technical Field

[0001] This utility model relates to the field of wire rope clamping technology, specifically a wire rope clamping device. Background Technology

[0002] In industrial fields such as lifting and transportation, construction, and mining hoisting, steel wire ropes are core force transmission components, and their stable fixation and safe braking depend on the reliable operation of steel wire rope clamps.

[0003] Traditional clamping tools typically use flat clamping blocks without asymmetrical design. The flat clamping block design makes it impossible to adapt to the surface contour of the wire rope, resulting in poor fit and potential slippage. The asymmetrical design causes the clamping force on the wire rope to be uneven when clamping it, leading to excessive local stress on the wire rope, deformation or surface wear, and shortening its service life.

[0004] Therefore, a wire rope clamp is proposed to solve the problems mentioned above. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a wire rope clamp that can solve the problems of slippage and damage to the wire rope.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a base plate and nuts. The base plate is configured as a two-section structure, with one section being an arc-shaped plate and the other section being a cuboid plate. At least two clamping bases are fixedly mounted on the upper end of the base plate. Several threaded posts are fixedly mounted on the upper end of each clamping base. A fastening plate and a pressure plate are mounted on the upper end of each clamping base. The fastening plate and the pressure plate are sleeved on the outside of the threaded posts. Several nuts are mounted on the upper end of the pressure plate and the fastening plate, and the nuts are threadedly engaged with the threaded posts. At least two driving blocks are fixedly mounted on the lower end of the pressure plate. A clamping moving block is slidably mounted on the inner side of the clamping base, and a clamping block is fixedly mounted on the side of the clamping moving block away from the clamping base.

[0007] Preferably, the clamping base is inclined and the two clamping bases are mirror images of each other.

[0008] Preferably, the threaded posts at the upper end of the clamping base are configured as a group, and the two groups of threaded posts at the upper ends of the two clamping bases are arranged in a mirror image. The fastening plate and the pressure plate are respectively sleeved on the outside of the two mirror-arranged threaded posts.

[0009] Preferably, the pressure plate is disposed on one side close to the arc-shaped structure of the base plate, and the fastening plate and the pressure plate do not contact each other.

[0010] Preferably, the two drive blocks are arranged in a mirror image, the two clamping moving blocks inside the clamping base are arranged in a mirror image, and the drive block is disposed above the clamping moving block.

[0011] Preferably, the drive block is configured as a trapezoidal structure, and the side of the drive block closest to the pressure plate has a larger bottom surface.

[0012] Preferably, the clamping block body is configured as a cuboid structure, and a semi-cylindrical cavity is provided on the side of the clamping block body away from the clamping moving block. A plurality of rhomboid friction particles are fixedly arranged in the clamping block cavity.

[0013] Compared with the prior art, the present invention provides a wire rope clamp with the following advantages:

[0014] 1. This utility model uses a structure in which the driving block and the clamping moving block are mirrored, with the driving block located above the clamping moving block, to ensure that the clamping force of the two clamping blocks on the wire rope is consistent, effectively avoiding local wear or deformation of the wire rope due to uneven force.

[0015] 2. This utility model has a cuboid body with a semi-cylindrical cavity on the side away from the clamping moving block. The clamping block with diamond-shaped friction particles is fixed in the cavity. The semi-cylindrical cavity can fit with the surface of the wire rope to increase the contact area. The diamond-shaped friction particles can increase the friction between the clamping block and the wire rope. Under the dual action, the wire rope is prevented from sliding during clamping, and rigid contact is avoided to prevent damage to the surface of the wire rope. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] Example:

[0023] Please see Figure 1 one Figure 4 A wire rope clamp in this embodiment includes a base plate 1 and nuts 5. The base plate 1 is configured as a two-section structure, with one section being an arc-shaped plate structure and the other section being a cuboid plate structure. At least two clamping bases 2 are fixedly provided on the upper end of the base plate 1. Several threaded posts 3 are fixedly provided on the upper end of the clamping bases 2. Fastening plates 4 and pressure plates 6 are provided on the upper end of the clamping bases 2. The fastening plates 4 and pressure plates 6 are sleeved on the outside of the threaded posts 3. Several nuts 5 are provided on the upper end of the pressure plates 6 and fastening plates 4, and the nuts 5 are threadedly engaged with the threaded posts 3. At least two driving blocks 7 are fixedly provided on the lower end of the pressure plates 6. A clamping moving block 8 is slidably provided on the inner side of the clamping base 2. A clamping block 9 is fixedly provided on the side of the clamping moving block 8 away from the clamping base 2.

[0024] During operation, the wire rope passes between the two clamping blocks 9. If the wire rope is to be clamped, the nut 5 at the top of the pressure plate 6 is tightened manually or with a tool, causing the nut 5 to move downward. The pressure plate 6 moves downward under the action of the nut 5, which in turn drives the drive block 7 to press down. The drive clamping moving block 8 slides along the inner side of the clamping base 2, eventually bringing the two clamping blocks 9 closer together and clamping the wire rope. At the same time, tightening the pressure plate 6 and the nut 5 at the top of the fastening plate 4 can further enhance the overall structural stability. If the nut 5 is not tightened, the sliding action of the wire rope will push the clamping blocks 9 to slide, causing the two clamping blocks 9 to move away from each other.

[0025] Please see Figure 1 The clamping base 2 is set at an angle, and the two clamping bases 2 are set in a mirror image;

[0026] The tilted design causes the two clamping blocks 9 to move closer to each other when they slide under the action of the driving block 7, thereby clamping the wire rope.

[0027] Please see Figure 1 The threaded posts 3 at the upper end of the clamping base 2 are set as a group, and the two groups of threaded posts 3 at the upper end of the two clamping bases 2 are set in a mirror image. The fastening plate 4 and the pressure plate 6 are respectively sleeved on the outside of the two mirror-set threaded posts 3.

[0028] This grouped mirror design ensures that the fastening plate 4 and the pressure plate 6 are subjected to uniform force, which enhances the overall structural stability and avoids uneven force distribution.

[0029] Please see Figure 1 The pressure plate 6 is located on one side of the arc-shaped plate structure near the bottom plate 1, and the fastening plate 4 and the pressure plate 6 do not contact each other;

[0030] This layout ensures that the pressure plate 6 and the fastening plate 4 enhance the overall structural stability while preventing them from interfering with each other, thus avoiding the impact on overall stability when the pressure plate 6 is performing its clamping function.

[0031] Please see Figure 2 one Figure 3 The two drive blocks 7 are set in a mirror image, and the clamping moving blocks 8 inside the two clamping bases 2 are set in a mirror image, with the drive block 7 positioned above the clamping moving block 8.

[0032] When the pressure plate 6 moves down, the two drive blocks 7 apply pressure to the two clamping moving blocks 8 simultaneously, causing the clamping moving blocks 8 to slide synchronously in a symmetrical direction, ensuring that the clamping force of the two clamping blocks 9 on the wire rope is the same, and avoiding damage to the wire rope due to uneven force.

[0033] Please see Figure 2 one Figure 3 The drive block 7 is configured as a trapezoidal structure, and the side of the drive block 7 closest to the pressure plate 6 is configured as a larger bottom surface;

[0034] When the pressure plate 6 moves downward, the inclined surface of the drive block 7 contacts the upper end surface of the clamping moving block 8. The guiding effect of the inclined surface is used to convert the vertical downward force of the pressure plate 6 into the horizontal moving force of the clamping moving block 8, thereby causing the two clamping blocks 9 to move closer to each other and achieve clamping.

[0035] Please see Figure 4 The main body of the clamping block 9 is set as a cuboid structure. A semi-cylindrical cavity is opened on the side of the main body of the clamping block 9 away from the clamping moving block 8. Several rhomboid friction particles are fixedly arranged in the cavity of the clamping block 9.

[0036] The semi-cylindrical cavity can completely fit the surface of the wire rope, increasing the contact area. The diamond-shaped friction particles can improve the friction between the clamping block 9 and the wire rope, preventing the wire rope from slipping during the clamping process.

[0037] The working principle of the above embodiment is as follows: During operation, the wire rope first passes between the two clamping blocks 9. When it is necessary to clamp the wire rope, the nut 5 at the upper end of the pressure plate 6 is tightened manually or with tools. The nut 5 moves downward along the threaded post 3, thereby pushing the pressure plate 6, which is sleeved on the outside of the threaded post 3, to move downward synchronously. The driving block 7 fixed at the lower end of the pressure plate 6 is pressed down accordingly. Since the driving block 7 has a trapezoidal structure and the side near the pressure plate 6 has a larger bottom surface, its inclined surface contacts the upper end surface of the clamping moving block 8 slidably disposed inside the clamping base 2. Under the guiding action of the inclined surface, the vertical downward force of the pressure plate 6 is converted into the horizontal moving force of the clamping moving block 8. Furthermore, since the clamping base 2 is inclined and mirror-like, the vertical downward force of the pressure plate 6 is converted into the horizontal moving force of the clamping moving block 8. As configured, the clamping moving block 8 slides along the inner side of the clamping base 2 and drives the clamping block 9 on the side away from the clamping base 2 to move closer to each other. The semi-cylindrical cavity on the clamping block 9 fits against the surface of the wire rope. The diamond-shaped friction particles in the cavity increase the friction between the two to prevent the wire rope from slipping and achieve reliable clamping. At the same time, the fastening plate 4 can be tightened by tightening the nut 5 at the upper end of the fastening plate 4. The fastening plate 4 is also sleeved on the outside of the threaded column 3 in the mirror arrangement and does not contact the pressure plate 6, which further enhances the overall structural stability. If the nut 5 is not tightened, the wire rope will push the clamping block 9 when it slips, causing the clamping moving block 8 to slide in the opposite direction along the clamping base 2, resulting in the two clamping blocks 9 moving away from each other and no clamping effect.

[0038] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. They are common knowledge in the field. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
