Description

Technical Field

[0001] The utility model belongs to the technical field of communication cable installation, and in particular relates to a communication cable installation wire pulling device. Background Art

[0002] With the development and popularization of communication technology, the installation coverage of communication infrastructure has gradually increased, which is reflected in the expansion of the installation coverage of communication infrastructure from economically prosperous urban areas to sparsely populated mountainous areas.

[0003] During the installation of communication infrastructure, the laying of communication cables is the focus of infrastructure installation. Specifically, during the installation process, after the communication poles are erected according to construction needs, the communication cables are hung on the communication poles.

[0004] In order to avoid interference from ground obstacles such as trees and high-rise buildings, communication towers and communication cables are often installed at a relatively high height. During the installation process, the cables need to be hung on the cable clamps, and the cables are dragged between the towers by pulling the cable clamps. However, in the actual pulling process, once the cable clamps or cables touch obstacles such as installation components on the towers, the tension increases, and the cables can easily detach from the cable clamps. It is more difficult to remove one or more strands of cables from the multiple cables, and in the high-altitude working environment, it is more difficult to lock the cables to the cable clamps again.

[0005] Therefore, in the actual working process, once the cable falls off, it is necessary to lock the cable again and continue to pull it. The essential reason for the above technical defects is that after the cable clamp clamps the end of the cable, the clamping surface is small and the stability is not high. Secondly, the cable clamp is easily pulled and hung on obstacles, causing the cable to be extremely tightened and detached from the clamp. Utility Model Content

[0006] Based on the above background, the purpose of the utility model is to provide a communication cable laying and pulling device.

[0007] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0008] A communication cable erection wire pulling device, comprising a cable wire pulling mechanism, the cable wire pulling mechanism comprising a wire pulling seat, a wire pulling assembly is hinged on the wire pulling seat, the wire pulling assembly comprises a wire pulling beam, and the wire pulling beam is hinged on the wire pulling seat;

[0009] The cable-stayed beam is fixedly connected with a plurality of locking structures for locking cables, wherein the locking structures include a limit tube fixedly connected to the cable-stayed beam, a locking wire seat is threadedly connected to the limit tube, and a wire hole communicating with a lumen of the limit tube is opened on the locking wire seat;

[0010] The cable passes through the cable hole and into the limit tube;

[0011] The locking seat is threadedly connected with a plurality of locking screws, and after the cable passes through the cable hole, the locking screws are locked on the cable;

[0012] A spring sheath communicating with the wire hole is fixedly connected to the wire locking seat, and the cable passes through the spring cavity of the spring sheath and then enters the wire locking seat.

[0013] Preferably, the transverse cross-section of the wire pull seat is trapezoidal.

[0014] Preferably, a plurality of hinge ports are provided on the right side wall of the wire pulling seat, and a plurality of hinge tongue plates hinged in the hinge ports are fixedly connected to the wire pulling beam;

[0015] A long pin is fixedly connected to the wire pulling seat, and the tongue flap is hinged to the long pin.

[0016] Preferably, a pull ring rod is fixedly connected to the left side wall of the wire pull seat.

[0017] Preferably, a resistance roller mechanism is provided at the bottom of the wire pulling seat. During the wire pulling process, when the wire pulling seat touches an obstacle, the obstacle rolls through the resistance roller mechanism.

[0018] Preferably, the abutting roller mechanism comprises a first roller body and a second roller body;

[0019] The bottom of the wire pulling seat is provided with a mounting groove for a limited first roller body and a second roller body, and the first roller body and the second roller body are rotatably connected in the mounting groove.

[0020] Preferably, both ends of the first roller body and the second roller body are respectively fixedly connected with a rotating shaft, and the rotating shaft is rotatably connected to the groove wall of the installation groove.

[0021] Preferably, the length of the second roller body is greater than the length of the first roller body.

[0022] Preferably, the left side wall of the tension beam is threadedly connected to the hinge tongue plate through a plurality of connecting screws;

[0023] The connecting screw rod is integrally formed with hexagonal convex ridges.

[0024] The utility model has the following beneficial effects:

[0025] 1. A locking structure with several locking cables fixedly connected to the wire tensioning beam, the locking structure includes a limit tube fixedly connected to the wire tensioning beam, a locking wire seat is threadedly connected to the limit tube, and a wire hole connected to the lumen of the limit tube is opened on the lock wire seat; in this way, the length of the limit locking cable is increased, specifically, the cable passes through the wire hole to be limited in the limit tube. Since the limit tube has a certain length, the locking end of the cable has a longer length and is limited in the limit tube. In actual work, the outer jacket of the cable is elastically squeezed in the lumen of the limit tube. At the same time, several locking screws are threadedly connected to the lock wire seat. After the cable passes through the wire hole, the locking screw is locked on the cable. In this way, the cable is locked, and the cable is elastically squeezed in the limit tube to fully lock and position the cable, so as to prevent the cable from falling off during pulling.

[0026] 2. A resistance roller mechanism is provided at the bottom of the cable pulling seat. During the cable pulling process, when the cable pulling seat touches an obstacle, the resistance roller mechanism rolls through. Specifically, when the cable passes through a pulley or a wire wheel, the traditional wire clamp is easy to get stuck on the pulley or the wire wheel. When the cable pulling seat passes through the resistance roller mechanism, the resistance roller mechanism at the bottom smoothly passes through by rolling. This avoids the cable getting stuck on an obstacle, causing the cable to be over-tensioned, easily falling off, or breaking. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Example 1

[0037] like Figure 1-4 As shown, a communication cable laying and pulling device includes a cable pulling mechanism, wherein the cable pulling mechanism includes a pulling seat 1 (trapezoidal in shape), a pulling assembly is hinged on the pulling seat 1, and the pulling assembly includes a pulling beam 3, which is hinged on the pulling seat 1.

[0038] The specific hinge method is: a plurality of hinge ports 12 are provided on the right side wall of the cable pull seat 1, and a plurality of hinged tongue plates 31 hinged in the hinge ports 12 are fixedly connected to the cable pull beam 3 (the hinged tongue plate is fixed in the following manner: the left side wall of the cable pull beam 3 is threadedly connected to the hinged tongue plate through a plurality of connecting screws 32, and the connecting screws are integrally formed with hexagonal convex ridges, which facilitates disassembly). At the same time, a long pin shaft 13 is fixedly connected to the cable pull seat 1, and the hinged tongue plate 31 is hinged to the long pin shaft 13. The hinge method facilitates the adjustment of the direction of the cable in accordance with the direction of the pulling force during the pulling process.

[0039] The cable-stayed beam 3 is fixedly connected with a plurality of locking structures for locking cables, and the locking structures include a limit tube 42 fixedly connected to the cable-stayed beam 3, a locking wire seat 41 is threadedly connected to the limit tube 42, and a wire hole communicating with the lumen of the limit tube 42 is provided on the lock wire seat 41; in this way, the length of the limit locking cable is increased, specifically, the cable passes through the wire hole until it is limited in the limit tube 42. Since the limit tube 42 has a certain length, the locking end of the cable has a relatively long length and is limited in the limit tube 42. In actual operation, the outer jacket of the cable is elastically squeezed in the lumen of the limit tube 42.

[0040] The locking seat 41 is threadedly connected with a plurality of locking screws 411 (specifically, on the top, bottom and side walls of the locking seat 41). After the cable passes through the cable hole, the locking screws 411 are locked on the cable. The cable is locked in this way, and the cable is elastically squeezed in the limiting tube 42 to fully lock and position the cable, preventing the cable from falling off during pulling.

[0041] The above-mentioned wire lock seat 41 is fixedly connected with a spring sheath 43 connected to the wire hole, and the cable passes through the spring cavity of the spring sheath 43 and enters the wire lock seat 41. The spring sheath 43 (the spring sheath 43 is a spring of a certain length) is designed to protect the cable. Firstly, during the bending process of the cable, the spring sheath 43 plays a role in avoiding severe bending. Secondly, during the pulling process, especially during the bending and pulling process of the cable, the spring is used to form protection.

[0042] A pull ring rod 11 is fixedly connected to the left side wall of the pull wire seat 1. In actual work, the traction rope is hung on the pull ring rod 11 to achieve pulling.

[0043] Example 2

[0044] like Figure 1-4 As shown, based on the structure of Example 1, this embodiment is provided with a resistance roller mechanism 2 at the bottom of the wire pulling seat 1. During the wire pulling process, when the wire pulling seat 1 touches an obstacle, it rolls through the resistance roller mechanism 2. Specifically, when the cable passes through a pulley or a wire wheel, the traditional wire clamp is easy to get stuck on the pulley or the wire wheel, while when the wire pulling seat 1 passes through the resistance roller mechanism 2, it passes smoothly through the resistance roller mechanism 2 at the bottom by rolling. It avoids getting stuck on obstacles, causing the cable to be over-tensioned, easily fall off, or break.

[0045] Specifically, the abutting roller mechanism 2 includes a first roller body 21 and a second roller body 22; the bottom of the wire pulling seat 1 is provided with a mounting groove for limiting the first roller body 21 and the second roller body 22, and the first roller body 21 and the second roller body 22 are rotatably connected in the mounting groove. At the same time, the existing conventional rotation connection method is installed, and the two ends of the first roller body 21 and the second roller body 22 are respectively fixedly connected with a rotating shaft, and the rotating shaft is rotatably connected to the groove wall of the mounting groove.

[0046] The length of the second roller body 22 is greater than that of the first roller body 21. During use, when the second roller body 22 and the first roller body 21 touch an obstacle, they can fully contact the surface of the obstacle such as a pulley or a guide wheel and roll over the obstacle because they have a certain length.

[0047] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
