Description

Technical Field

[0001] The invention relates to the field of cable installation, and in particular to a cable installation auxiliary device. Background Art

[0002] During the cable installation process, a cable mesh is required to drag the cable.

[0003] Cable mesh is usually composed of woven wire rope mesh, connectors, and hanging ropes. It is used to drag various steel core aluminum stranded wires, insulated wires, ground wires, optical fibers, optical cables, and electrical cables during power construction. It has the advantages of light weight, large tensile load, and easy use.

[0004] However, when the existing cable mesh is used on the cable, it is necessary to use additional iron wires to tie the wire mesh to the cable to prevent the wire mesh from slipping when dragging. However, after the wire mesh is tied with iron wires, the wires at the tied parts of the wire mesh will bulge out, causing the cable mesh to be stuck or dragged unsmoothly due to the bulging part when the cable mesh is dragged through the guide wheel, guide frame, guide channel and other guide equipment.

[0005] Based on the above problems, the present invention is proposed. Summary of the invention

[0006] In order to overcome the disadvantage that after the wires are bundled with the wires in the wire rope mesh, the wires at the bundling part of the wire rope mesh will bulge out, causing the cable mesh to be stuck or dragged poorly due to the bulging of this part when it is dragged through guiding devices such as guide wheels, guide frames, and guide channels, the present invention provides a cable installation auxiliary device.

[0007] The technical solution of the present invention is: a cable installation auxiliary device, including a connector, a lifting rope, an adaptation ring and a braided mesh; one end of the connector is connected to the lifting rope, and the other end of the connector is connected to the mesh body; the mesh body is composed of a braided mesh and an adaptation ring distributed at intervals, and adjacent braided meshes and adaptation rings are fixedly connected; the adaptation ring is composed of a plurality of connecting pieces, and elastic parts are arranged between adjacent connecting pieces; a bundling groove and a receiving groove are opened on the adaptable ring, and the bundling groove and the receiving groove are connected; the outer diameters of the adaptable ring and the braided mesh are the same.

[0008] Furthermore, one end of the sling is detachably connected to the connector.

[0009] Furthermore, a connecting groove is provided on the adaption ring.

[0010] Furthermore, the accommodating groove is arranged on a side of the binding groove away from the suspension rope.

[0011] Furthermore, the depth of the bundling groove and the accommodating groove is greater than the diameter of the first bundling strip.

[0012] Furthermore, the depth of the connecting groove is greater than the diameter of the second bundling strip.

[0013] Furthermore, the braided mesh is braided with steel wire ropes.

[0014] Further, the inner side surface of the adaptation ring is roughened.

[0015] Further, the connector is tapered.

[0016] Furthermore, it also includes an expansion bag. The connector is set to be hollow and made of elastic deformable material. The expansion bag is connected to the connector. The expansion bag is provided with an inflation nozzle, and the inflation nozzle passes through the connector.

[0017] The beneficial effect is as follows: the present invention is provided with a bundling groove and a receiving groove, and the depth of the bundling groove and the receiving groove is greater than the diameter of the first bundling strip, so that the first bundling strip is hidden in the bundling groove and the receiving groove, and does not leak out to affect the present invention passing through the guiding device, thereby overcoming the problem that after the existing cable mesh is bundled with iron wire, the iron wire protrudes when passing through the guiding device, causing dragging jam or dragging difficulty.

[0018] The present invention uses the staggered fixing of the suspension ropes and the second bundling strips to bundle the cable nets side by side, so as to prevent the cables from being separated and affecting the cable dragging work. In addition, the present invention uses the connection groove and the gap between the two adaption rings to hide the second bundling strips, so as to prevent the second bundling strips from protruding after bundling and avoid affecting the subsequent dragging work.

DETAILED DESCRIPTION

[0021] The preferred technical solutions of the present invention are described in detail below with reference to the accompanying drawings. Example 1

[0022] A cable installation aid, such as Figure 1-8 As shown, it includes a connector 1, a hanging rope 2, an adaption ring 101 and a braided mesh sleeve 102; one end of the connector 1 is connected to the hanging rope 2, and the other end of the connector 1 is connected to the mesh sleeve body, and the connector 1 is tapered; The mesh body is composed of woven meshes 102 and adapting rings 101 which are distributed at intervals. The adapting rings 101 are distributed in odd numbers, and the woven meshes 102 are distributed in even numbers. The adjacent woven meshes 102 and adapting rings 101 are fixedly connected, and the number of adapting rings 101 is one more than the number of woven meshes 102. The adaptable ring 101 is composed of a plurality of connecting plates, and elastic members, such as springs, are arranged between adjacent connecting plates. The adaptable ring 101 is expanded and contracted by the extension and contraction of the elastic members to adapt to cables of different sizes; a bundling groove 1011 and a receiving groove 1012 are provided on the adaptable ring 101, and the bundling groove 1011 and the receiving groove 1012 are connected; the adaptable ring 101 and the braided mesh sleeve 102 have the same outer diameter, and the first bundling strip 200 is accommodated by the bundling groove 1011 and the receiving groove 1012 to prevent the first bundling strip 200 from leaking out when the cable is dragged and affecting the guiding device of the present invention.

[0023] One end of the sling 2 is detachably connected to the connector 1 .

[0024] The adaptable ring 101 is further provided with a connecting groove 1013 , and the connecting groove 1013 is used to accommodate the second binding strip 300 .

[0025] The accommodating groove 1012 is arranged on a side of the bundling groove 1011 away from the suspension rope 2 to adapt to the pulling direction of the cable and prevent the tightening part of the rope end of the first bundling strip 200 from popping out.

[0026] The depth of the bundling groove 1011 and the receiving groove 1012 is greater than the diameter of the first bundling strip 200, so that the first bundling strip 200 is hidden in the bundling groove 1011 and the receiving groove 1012 and does not leak out to affect the passing of the guiding device of the present invention.

[0027] The depth of the connecting groove 1013 is greater than the diameter of the second bundling strip 300, so that the second bundling strip 300 is hidden in the connecting groove 1013 and does not leak out to affect the passing of the guiding device of the present invention.

[0028] The braided mesh sleeve 102 is braided with steel wire ropes.

[0029] The inner side of the adaptable ring 101 is rough to better prevent the cable from slipping off.

[0030] When the present invention is used, the staff puts the present invention on the cable. During this process, the braided mesh 102 woven by the steel wire rope and the adaptable ring 101 are adaptively expanded and contracted to achieve tight coverage of the cable. Then the staff uses the first binding strip 200 to bind on the adaptable ring 101, and the first binding strip 200 is bound in the binding groove 1011, and the rope head tightening part of the first binding strip 200 is bent and pressed into the receiving groove 1012, so as to achieve the mesh body of the present invention being firmly fixed on the cable, and the mesh body is prevented from slipping off during the dragging process; Then, the sling 2 is pulled by the dragging device to move, thereby dragging the connector 1, the mesh body, and the cable to move, thereby realizing the dragging of the cable. In this process, the present invention and the cable pass through the guiding device in the dragging process in an orderly manner.

[0031] Furthermore, by providing a bundling groove 1011 and a receiving groove 1012, and the depth of the bundling groove 1011 and the receiving groove 1012 is greater than the diameter of the first bundling strip 200, the first bundling strip 200 is hidden in the bundling groove 1011 and the receiving groove 1012, and does not leak out to affect the passing of the guiding device of the present invention, thereby overcoming the problem that after the existing cable mesh is bundled with iron wire, the iron wire protrudes when passing through the guiding device, causing dragging jam or dragging difficulty.

[0032] Furthermore, when the existing cable mesh is used to pull two cables at the same time, two cable meshes are used, and the two cable meshes are dragged and pulled at the same time. There are problems: when the two cable meshes are pulled at the same time, they will form a V shape, such as Figure 8 As shown, the cable will be separated due to the V-shaped shape of the cable mesh, affecting the subsequent traction work; In view of the above problems, when two cables need to be pulled at the same time, the present invention refers to Figure 6-7 , put the two cable installation auxiliary devices side by side, and then fix the cables in the above manner, then remove the detachable end of the hanging rope 2 and the connector 1, and fix it on the other connector 1, as shown in the figure. Figure 6 The staggered state shown in the figure can make the traction force of the suspension rope 2 centered, and then the staff uses the second binding strip 300 to bind the two adjacent adaptation rings 101 together. The present invention uses the staggered fixing of the suspension rope 2 and the second binding strip 300 to bind the cable nets side by side to avoid the cables from being Figure 8 The second bundling strip 300 is accommodated in the connection groove 1013. Since the adaption ring 101 is annular, the rope head tightening part of the second bundling strip 300 can be hidden in the gap between the two adaption rings 101. Thus, the second bundling strip 300 is hidden through the connection groove 1013 and the gap between the two adaption rings 101, so as to avoid the second bundling strip 300 protruding after bundling and affecting the subsequent dragging work. Example 2

[0033] On the basis of Example 1, Figure 1-Figure 8 As shown, an expansion bag 301 is also included. The connector 1 is set to be hollow and made of elastic deformable material, such as rubber. The expansion bag 301 is connected to the connector 1. The expansion bag 301 is provided with an inflation nozzle 3011, and the inflation nozzle 3011 passes through the connector 1.

[0034] When the adaption ring 101 expands, the connector 1 can be deformed to adapt to the expansion of the adaption ring 101, which is similar to the connector head of the prior art, but there is a problem that the connector 1 needs to pass through the guide device. When the connector 1 passes through the guide device, such as a guide wheel, a guide frame, and a guide channel, when the towing device drags the connector 1 to move, the connector 1 will inevitably be squeezed with the guide wheel, the guide frame, and the guide channel, thereby causing the connector 1 to deform, so that the adaption ring 101 connected to the connector 1 is stuck at the guide wheel, the guide frame, and the guide channel, resulting in the dragging being stuck or the dragging being unsmooth. Therefore, the present invention can pre-inject or release gas into the expansion bag 301 through the inflation nozzle 3011, so that the expansion bag 301 can fully fill the connector 1 to adapt to the expansion of the adaption ring 101, thereby avoiding the problem that the connector 1 is squeezed and deformed during the dragging process, and the dragging is stuck or the dragging is unsmooth.

[0035] It should be understood that the above description is only for exemplary purposes and is not meant to limit the present invention. Those skilled in the art will appreciate that variations of the present invention will be included within the scope of the claims herein.
