Description

Technical Field

[0001] This utility model belongs to the field of cable laying technology, specifically relating to a cable laying tensioning device. Background Technology

[0002] Cable laying refers to the process of laying and installing cables along a surveyed route to form a cable line. Depending on the application, cable laying can be divided into various methods such as overhead, underground, underwater, wall, and tunnel. During the cable laying process, a cable laying frame is needed to stretch and lay the cable.

[0003] The aforementioned device lacks a cable-laying frame structure for auxiliary stretching during use, causing the cable to wrap around the rollers one loop at a time during the cable laying process. This can lead to the cable becoming stuck due to mutual compression from the loops. Forcibly stretching the cable during laying can easily damage it. Based on the shortcomings of existing technology, this utility model designs a cable laying stretching device. Utility Model Content

[0030] Example 2

[0031] Please see Figure 3-5 The present invention provides the following technical solution:

[0032] The clamping mechanism 4 and the tensioning mechanism 3 include a fixed frame 301, a connecting hole 302, a telescopic cylinder 303, a telescopic rod 304, a slider 305, and a groove 306. The fixed frame 301 is fixedly installed on the top of the wire pulling cart 1. A connecting hole 302 is provided on one side of the fixed frame 301. The telescopic cylinder 303 is located on the top of the wire pulling cart 1. The telescopic rod 304 is slidably connected inside the telescopic cylinder 303. A slider 305 is fixedly connected to one side of the telescopic rod 304. A groove 306 is provided inside the slider 305.

[0033] The clamping mechanism 4 includes a clamping plate 401, an anti-slip plate 402, a connecting plate 403, a sliding hole 404, a threaded groove 405, a bidirectional threaded rod 406, and a turntable 407. The clamping plate 401 is set on the top of the wire pulling cart 1. An anti-slip plate 402 is fixedly connected to one side of the clamping plate 401. A connecting plate 403 is fixedly connected to the lower surface of the clamping plate 401. A sliding hole 404 is opened on one side of the connecting plate 403. A threaded groove 405 is opened on one side of the connecting plate 403. A bidirectional threaded rod 406 is threadedly connected inside the threaded groove 405. A turntable 407 is fixedly connected to one side of the bidirectional threaded rod 406.

[0034] The slider 305 is slidably connected inside the fixed frame 301, and the telescopic rod 304 is slidably connected inside the connecting hole 302.

[0035] The connecting plate 403 is slidably connected inside the slide groove 306, and the bidirectional threaded rod 406 is rotatably connected inside the slider 305.

[0036] The clamping plate 401 is disposed on one side of the cable 205, and the connecting plate 403 is slidably connected to the top of the slider 305.

[0037] Further explanation is needed: Inserting the insertion rod 202 into the card hole 204 locks the cable roller 203. Then, rotating the turntable 407 causes the bidirectional threaded rod 406 to drive the two clamping plates 401 to clamp the cable 205. At this time, the telescopic cylinder 303 controls the extension of the telescopic rod 304, which drives the slider 305 connected to it to move accordingly. Since the slider 305 is connected to the clamping plate 401 and the anti-slip plate 402, the slider 305 will also drive the clamped cable 205 to move backward a certain distance through the clamping plate 401 and the anti-slip plate 402 during its backward movement. This allows the multiple coils of cable 205 that are squeezed together to unravel and no longer be affected by the compression when exiting the cable. Finally, the front end of the cable 205 can be pulled to continue exiting the cable. This device is convenient for stretching and unraveling the multiple coils of cable 205 that are squeezed together and cannot be discharged.

[0038] Working principle: When a cable laying tensioning device is used, a bearing plate 2 is first set on the top of the cable pulling cart 1. The bearing plate 2 supports the cable roller 203. The cable roller 203 has a locking hole 204 on both sides. The insertion rod 202 on the protrusion 201 on one side of the bearing plate 2 can be inserted into the locking hole 204 to limit the cable roller 203. A connecting frame 103 is connected to the top of the cable pulling cart 1 through a support plate 102. A connecting cylinder 105 is set inside the connecting frame 103. The connecting cylinder 105 guides the cable 205. A tensioning mechanism 3 and a clamping mechanism 4 are set on the top of the cable pulling cart 1. The clamping mechanism 4 clamps the cable 205. The tensioning mechanism 3 moves the clamping mechanism 4 on the top of the cable pulling cart 1, and also moves the cable 205 on the top of the cable pulling cart 1.

[0039] When it is necessary to stretch and untangle the multi-turn cable 205 that is unable to be discharged due to mutual compression, firstly, insert the rod 202 into the inside of the clamping hole 204 to lock the cable roller 203. Then, rotate the turntable 407 so that the bidirectional threaded rod 406 drives the two clamping plates 401 to clamp the cable 205. At this time, the telescopic cylinder 303 controls the extension of the telescopic rod 304 to drive the slider 305 connected to it to move accordingly. Since the slider 305 is connected to the clamping plate 401 and the anti-slip plate 402, the slider 305 will also drive the clamped cable 205 to move backward a certain distance through the clamping plate 401 and the anti-slip plate 402 during the backward movement, so that the multi-turn cable 205 that is unable to be discharged due to mutual compression can be untangled. Finally, the front end of the cable 205 can be pulled to continue to discharge. This device is convenient for stretching and untangling the multi-turn cable 205 that is unable to be discharged due to mutual compression.

[0040] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
