Description

Technical Field

[0001] The invention relates to the technical field of cable installation, and in particular to a tensioning installation device and an installation method for overhead lines. Background Art

[0002] Overhead lines mainly refer to overhead open lines, which are erected above the ground. They use insulators to fix the transmission wires on the towers erected on the ground to transmit electricity. They are easy to erect and maintain, and have low costs, but they are easily affected by weather and environment (such as strong winds, lightning strikes, dirt, ice and snow, etc.) and cause failures. At the same time, the entire transmission corridor occupies a large area of ​​land, which is easy to cause electromagnetic interference to the surrounding environment.

[0003] Chinese patent CN118373253B discloses a cable quick pulling device, which is equipped with a first connecting block and a first camera. When the cable is transported through the conveyor belt body, the vertical position of the first connecting block can be adjusted by the first electric telescopic rod. The state of the outer wall of each conveyor sheet can be photographed by the first camera to prevent the conveyor sheet itself from being damaged or sunken inward due to friction after a period of use, thereby affecting the conveying efficiency of the conveyor belt body for the cable, and at the same time prevent the rough side wall of the damaged conveyor sheet from causing wear on the outer wall of the cable.

[0004] When the above-mentioned tensioning installation device is in use, the middle cable is clamped and conveyed by the conveying plates on both sides. Only a single cable can be pulled, and multiple cables cannot be pulled at the same time, which will affect the overall cable laying efficiency. In addition, due to the different laying environments, layouts, and paths of each cable, the lengths of the cables will vary. As a result, when the cables are pulled to tighten, some cables are already in a tightened state, and there are cables on the same roller that have not yet reached a tightened state.

[0015] To achieve the above object, the present invention provides the following technical solution: a method for installing an overhead line, comprising the following steps: First, all the cables laid in a row are fixed on the corresponding take-up sleeves, and the stepper motor arranged in the shell bracket drives the driving roller to rotate in the shell bracket, and the matching blocks at both ends of the clamping assembly are manually slid out from the take-up sleeve, and the extended matching blocks are clamped in the limiting clamping grooves at both ends of the driving roller, so that the driving roller drives the clamped take-up sleeve to rotate and take up the wire at the same time while rotating. The cable will pass through the bottom of the limiting roller and be tightly wound around the corresponding take-up sleeve. During the take-up process, The reciprocating component on one side is driven to make the cable evenly wound on the take-up sleeve, and the cable located between the two poles is gradually pulled to a horizontal and straight state. The unlocking component can simultaneously drive the matching blocks at both ends to move out of the limiting slots, so that the take-up sleeve that is already in a taut state stops taking up the wire, and the limit component can limit the canceled take-up sleeve to prevent the taut cable from pulling the canceled take-up sleeve to pay out the wire in reverse. The other take-up sleeves that have not been canceled continue to rotate with the driving roller to take up the wire.

[0016] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects: 1. By means of the wire-reeling sleeves arranged in parallel on the driving roller, a row of cables being laid can be reeled in and tightened at the same time. By collecting and straightening multiple wire harnesses at the same time, the time for individually reeling in each wire harness can be reduced, thereby improving the efficiency of the overall operation. The unlocking component can simultaneously drive the matching blocks at both ends to be moved out of the limit card slots, so that the wire-reeling sleeve that is already in a tightened state stops reeling in, and the remaining wire-reeling sleeves that have not been canceled continue to rotate with the driving roller to reel in. By canceling the reeling in of the tightened cables and stopping the reeling in, the continuity of the reeling process can be ensured, and the entire reeling system will not stagnate because some cables have been tightened, ensuring that other untightened cables can continue to be reeled in, thereby ensuring consistent laying effects.

[0017] 2. By pulling the handle corresponding to the wire take-up sleeve, the movement of the handle will drive the sliding rack 1 to slide on the outer shell bracket, and the meshing folding spring sheet 1 above the sliding rack 1 will repeatedly drive the meshing sliding rack 2 to slide in opposite directions, so that the L-shaped slides 1 and 2 on both sides expand and slide outward, pushing the matching blocks on both sides to slide into the placement groove to squeeze the folding spring sheet 1, and the two card points can be released at the same time by pulling once, which reduces the operation steps, saves time, and improves the operation efficiency, so that the matching card block is connected between the fixed card blocks for limiting, thereby improving the stability and reliability of the equipment, and the staff does not need to pull the handle for a long time, avoiding fatigue and discomfort caused by long-term operation.

[0018] 3. By canceling the clamping connection between the take-up sleeve and the driving roller, the corresponding reciprocating assembly will also stop working and will no longer pull the taut cable to reciprocate, which helps to prevent operational risks caused by excessive tension or disorder of the cable, thereby reducing cable wear and damage and extending the service life of the cable. The torsion spring shaft will drive the limiting ratchet block to clamp with the ratchet ring on one side, so that the limited take-up sleeve cannot rotate on the driving roller, preventing the taut cable from pulling the canceled take-up sleeve to release the wire in reverse.
