Description

Technical Field

[0001] This application relates to the field of cable traction equipment technology, specifically to a cable traction rubber block and a conveyor belt. Background Technology

[0002] During cable laying, the traction machine is a key piece of equipment for completing long-distance cabling. Its core relies on the friction provided by the rubber blocks covering the conveyor belt to clamp the cable and pull it forward, while ensuring that the outer sheath or insulation layer of the cable is not damaged.

[0003] Traditional rectangular rubber blocks are widely used due to their ease of manufacture. When clamping cables, their sharp edges serve as the initial and final contact points with the cable sheath, resulting in extremely high local pressure due to the minimal contact area. This high pressure repeatedly scratches the cable sheath or insulation layer, easily causing cuts or even damage to the cable. Simultaneously, the sharp edges themselves suffer from abnormal wear and chipping due to the high pressure and friction. Damage to the cable sheath or insulation layer directly impairs the electrical performance, waterproofing, and lifespan of the circuit, creating potential hazards such as short circuits and leakage, and increasing repair costs. Wear on the rubber block itself leads to a sharp reduction in the effective friction surface, significantly shortening its lifespan.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the background technology of this disclosure and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0005] In view of at least one of the above technical problems, this disclosure provides a cable traction block, which mainly solves the technical problem that traditional cable traction blocks are prone to cutting the cable sheath and have severe abnormal chipping and wear.

[0006] According to one aspect of this disclosure, a cable traction rubber block is provided, characterized in that it includes a rubber block body, a contact rubber block disposed on the upper surface of the rubber block body, and a connector disposed below the rubber block body for connection with a corresponding track; the rubber block body is an elongated rectangular block; the contact rubber block is two cylindrical protrusions arranged along the length direction of the rubber block body and symmetrical about the transverse midsection of the rubber block body, and the two cylindrical protrusions are arranged in a V-shape.

[0007] In some embodiments of this disclosure, a V-shaped groove is provided at the middle of the upper surface of the adhesive block body, and the contact adhesive block is located at the V-shaped groove.

[0008] In some embodiments of this disclosure, the two cylindrical protrusions of the contact block are provided with at least two grooves along the axial direction of their cylindrical surfaces.

They are used only for the convenience of describing this application 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 application. Furthermore, the terms "connection" and "linkage" in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0025] Unless otherwise specified, the unit modules (components, structures, mechanisms) or sensors involved in the following embodiments are all conventional commercially available products.

[0026] This application provides a cable traction block that uses a cylindrical contact block to protect the cable and extend the block's lifespan. Furthermore, by creating a groove on the upper surface of the block body, the problem of excessively large traditional traction machines is solved, achieving a lightweight design. Adding a buffer plate extends the traction machine's lifespan and reduces maintenance costs.

[0027] To better understand the technical solution of this application, the above technical solution will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Example 1 This example discloses a cable traction rubber block; see [link / reference]. Figure 1 as well as Figure 2 It includes a main body of adhesive block 11, a contact adhesive block 12, and a connector 13.

[0029] The main body 11 of the rubber block is the base of the entire cable traction rubber block 1. It is a long rectangular rubber block that provides a platform for the force and installation of other components. The contact rubber block 12 is located on the upper surface of the main body of the rubber block. It consists of two cylindrical rubber protrusions along the length of the main body of the rubber block 11. The two cylindrical protrusions are symmetrical about the transverse mid-section of the main body of the rubber block 11 and are combined in a V-shape. This contact surface design can not only hold the cable in the bottom corner of the V-shape and increase the traction stability, but also prevent the mutual wear between the rubber block and the cable by relying on the cylindrical surface without sharp edges. The connector 13 is located below the main body of the rubber block 11 and is used to connect the cable traction rubber block and the track 2.

[0030] The upper surface of the rubber block body 11 is provided with a V-shaped groove along its transverse centerline, and the contact rubber block 12 is located on the V-shaped groove. The V-shaped groove on the upper surface of the rubber block body 11 allows the position of the contact rubber block 12 to be closer to the track 2, thereby making the contact position between the cable traction rubber block 1 and the cable 3 closer to the track. This design can make the overall traction machine lighter.

[0031] The contact rubber block 12 has two grooves along the axial direction of the cylindrical surface. These grooves, perpendicular to the cable, enhance the lateral elasticity of the rubber, allowing the rubber block to fit more tightly against the curved surface of the cable 3, thus increasing the effective contact area. The grooves, also perpendicular to the cable 3, disperse contact stress, preventing excessive pressure concentration and distributing pressure to multiple independent contact blocks. Simultaneously, the grooves serve as heat dissipation channels, increasing the heat dissipation surface area and preventing the rubber from softening and failing.

[0032] The main body 11 of the adhesive block, the contact adhesive block 12, and the connecting part 13, which is a cylindrical adhesive block, are integrally molded. This integral molding design greatly reduces the cost and difficulty of producing the cable traction adhesive block 1, improves production efficiency, and gives the cable traction adhesive block 1 higher structural strength, rigidity, and precision.

[0033] When working Figure 3 , Figure 4 As shown, the cable traction block 1 is mounted on the track 2 via a cylindrical connector 13. The contact block 12 in the cable traction block 1 clamps and fixes the cable 3 within the V-shaped bottom corner of the contact block 12 via a corresponding block or pressure roller, allowing it to be pulled along with the movement of the track. The arc-shaped surface design of the contact block 12 prevents the cable from being cut or squeezed by sharp edges when it first contacts the cable traction block 1 and when it is about to separate from it, thus protecting the cable 3 and extending the lifespan of the contact block 12.

[0034] Example 2 This example discloses a cable traction rubber block; see [link / reference]. Figure 5 It includes a main body of adhesive block 11, a contact adhesive block 12, and a connector 13.

[0035] The main body 11 of the rubber block is the base of the entire cable traction rubber block 1. It is a long rectangular metal block that provides a platform for the force and installation of other components. The contact rubber block 12 is bonded to the upper surface of the main body 11. It consists of two cylindrical rubber protrusions along the length of the main body 11. The two cylindrical protrusions are symmetrical about the transverse midsection of the main body 11 and are combined in a V-shape. This contact surface design can not only hold the cable in the bottom corner of the V-shape and increase the traction stability, but also prevent the mutual wear between the rubber block and the cable by relying on the cylindrical surface without sharp edges. The connector 13 is a bolt that extends from the lower sides of the main body 11 and is used to connect the cable traction rubber block 1 to the track 2.

[0036] The upper surface of the rubber block body 11 is provided with a V-shaped groove along its transverse centerline, and the contact rubber block 12 is located on the V-shaped groove. The V-shaped groove on the upper surface of the rubber block body 11 allows the position of the contact rubber block 12 to be closer to the track 2, thereby making the contact position between the cable traction rubber block 1 and the cable 3 closer to the track. This design can make the overall traction machine lighter.

[0037] The contact rubber block 12 has two grooves along the axial direction of the cylindrical surface. These grooves, perpendicular to the cable, enhance the lateral elasticity of the rubber, allowing the rubber block to fit more tightly against the curved surface of the cable 3, thus increasing the effective contact area. The grooves, also perpendicular to the cable 3, disperse contact stress, preventing excessive pressure concentration and distributing pressure to multiple independent contact blocks. Simultaneously, the grooves serve as heat dissipation channels, increasing the heat dissipation surface area and preventing the rubber from softening and failing.

[0038] At work, with Figure 3 , Figure 4 The cable traction block 1 is mounted on the track 2 via a bolted connector 13. The contact block 12 within the cable traction block 1 clamps and fixes the cable 3 within the V-shaped bottom corner of the contact block 12 via a corresponding block or pressure roller, allowing it to be pulled along with the track's movement. The arc-shaped surface design of the contact block 12 prevents the cable from being cut or squeezed by sharp edges when initially contacting the cable traction block 1 or preparing to separate from it, thus protecting the cable 3 and extending the lifespan of the contact block 12.

[0039] Example 3 This example discloses a cable traction rubber block; see [link / reference]. Figure 6 It includes a rubber block body 11, a contact rubber block 12, a connector 13, and a buffer plate 14.

[0040] The main body 11 of the rubber block serves as the base for the entire cable traction rubber block 1. It is a long, rectangular rubber block that provides a platform for the stress and installation of other components. The contact rubber block 12 is located on the upper surface of the main body and consists of two cylindrical rubber protrusions along the length of the main body 11. These two protrusions are symmetrical about the transverse mid-section of the main body 11 and form a V-shape. This contact surface design not only secures the cable within the bottom corner of the V-shape, increasing traction stability, but also prevents mutual wear between the rubber block and the cable due to the smooth cylindrical surfaces. The buffer plate 14 is connected to the main body 11 by bolts. Below the buffer plate is a connector 13 for connecting the cable traction rubber block to the track 2. The buffer plate prevents the connection between the cable traction rubber block 1 and the track from becoming rigid, effectively solving the problem of fatigue fracture or plastic deformation of metal components such as tracks in traditional traction machines due to stress concentration. This extends the life of the traction machine and reduces maintenance costs.

[0041] The upper surface of the rubber block body 11 is provided with a V-shaped groove along its transverse centerline, and the contact rubber block 12 is located on the V-shaped groove. The V-shaped groove on the upper surface of the rubber block body 11 allows the position of the contact rubber block 12 to be closer to the track 2, thereby making the contact position between the cable traction rubber block 1 and the cable 3 closer to the track. This design can make the overall traction machine lighter.

[0042] The contact rubber block 12 has two grooves along the axial direction of the cylindrical surface. These grooves, perpendicular to the cable, enhance the lateral elasticity of the rubber, allowing the rubber block to fit more tightly against the curved surface of the cable 3, thus increasing the effective contact area. The grooves, also perpendicular to the cable 3, disperse contact stress, preventing excessive pressure concentration and distributing pressure to multiple independent contact blocks. Simultaneously, the grooves serve as heat dissipation channels, increasing the heat dissipation surface area and preventing the rubber from softening and failing.

[0043] The main body 11 of the rubber block and the contact rubber block 12 are integrally molded parts, and the buffer plate 14 and the connecting part 13, which is a cylindrical rubber block, are integrally molded parts. These two integrally molded designs greatly reduce the cost and difficulty of producing the cable traction rubber block 1, improve production efficiency, and give the cable traction rubber block 1 higher structural strength, rigidity and precision.

[0044] When working Figure 3 , Figure 4 As shown, the cable traction block 1 is mounted on the track 2 via a cylindrical connector 13. The contact block 12 in the cable traction block 1 clamps and fixes the cable 3 within the V-shaped bottom corner of the contact block 12 via a corresponding block or pressure roller, allowing it to be pulled along with the movement of the track. The arc-shaped surface design of the contact block 12 prevents the cable from being cut or squeezed by sharp edges when it first contacts the cable traction block 1 and when it is about to separate from it, thus protecting the cable 3 and extending the lifespan of the contact block 12.
