Description

Technical Field

[0001] This utility model relates to the field of cable traction machine technology, specifically to a pipeline cable traction machine. Background Technology

[0002] High-voltage cables are power cables used for electricity transmission and are generally buried underground. When burying high-voltage cables, a conduit needs to be laid underground, and then the high-voltage cable is passed through the conduit. The conduit wraps around the high-voltage cable to protect it. Most traction machines use a pull rope to pull the high-voltage cable through the conduit. A wire mesh sleeve is attached to the end of the pull rope. In practice, workers pass the pull rope through the conduit, then place the wire mesh sleeve over one end of the high-voltage cable, wrap the wire mesh sleeve with multiple iron wires, and then tighten the iron wires with pliers to connect the wire mesh sleeve to the high-voltage cable. Finally, the high-voltage cable is pulled through the conduit using the pull rope. After the high-voltage cable passes through the conduit, the iron wires are loosened with pliers, and the wire mesh sleeve is removed from the high-voltage cable. Connecting the pull rope to the high-voltage cable requires tightening the iron wires with pliers. Disassembling the cable and high-voltage cable requires using pliers to tighten the wires, and with multiple wires involved, the operation is cumbersome and time-consuming. A Chinese patent (authorization announcement number CN112542809A) discloses a cable laying and pulling device. This patented technology uses a wireless module on the cable traction force measuring device and a receiver outside the underground pipeline. The antenna and ground connectors of the wireless module are electrically connected to the cable and wire rope, respectively, with the other end of the wire rope grounded. This allows the cable to act as an antenna to transmit wireless signals, facilitating signal transmission to the receiver via the cable outside the underground pipeline, ensuring smooth signal transmission and real-time monitoring of measurement data. However, this device requires tools to fix the cable, which can easily cause wear on the cable sheath, resulting in low efficiency. Furthermore, the device is too large and difficult to carry, limiting its practicality. Therefore, those skilled in the art have provided a pipeline cable pulling machine to solve the problems mentioned in the background. Summary of the Invention

Example

[0025] Please see Figures 1-6 In this embodiment, a pipeline cable traction machine is provided, including a traction machine body 1. A pulley frame 2 is fixedly connected to the outer wall of the front end of the traction machine body 1. A pulley 3 is installed on the pulley frame 2. An external threaded pipe 11 is provided in the middle of the front side of the traction machine body 1. A cavity 12 is provided in the middle of the interior of the traction machine body 1. A cavity 2 13 is provided on the left side of the cavity 12 and is connected to the external threaded pipe 11. Threaded holes 14 penetrating the traction machine body 1 are symmetrically opened in the middle of the top and bottom of the cavity 12.

[0026] The external threaded pipe 11 is provided with a clamping sleeve 4. The internal thread 41 on the inner wall of the rear end of the clamping sleeve 4 is threadedly engaged with the external threaded pipe 11. Support blocks 42 are symmetrically provided on both sides of the front end of the clamping sleeve 4. Elastic locking pieces 421 are symmetrically provided on the inner side of the top of the support block 42.

[0027] A threaded rod 5 is threadedly connected at the threaded hole 14. A knob 51 is provided at the outer end of the threaded rod 5, and a clamping block 52 is fixedly connected to the inner end of the threaded rod 5.

[0028] A drive wheel seat 6 is fixedly connected to the outer wall of the rear end of the traction machine body 1, and an electric wheel 7 is installed on the drive wheel seat 6.

[0029] Specifically, there are four pulley frames 2, which are evenly spaced and fixed on the outer wall of the front end of the traction machine body 1, and each of the four pulley frames 2 is equipped with a pulley 3; the outer side of the pulley 3 is on the same horizontal plane as the outer side of the electric wheel 7.

[0030] The front diameter of the elastic locking plate 421 is larger than the inner diameter of the external threaded tube 11, the front diameter of the elastic locking plate 421 is larger than the rear diameter of the elastic locking plate 421, and the rear diameter of the elastic locking plate 421 is larger than the cable diameter; there are two threaded rods 5, which are symmetrically arranged in the threaded hole 14 between the top and bottom of the cavity 12; the inner side of the clamping block 52 is in contact with the outer wall of the cable, and the top of the front and rear sides of the clamping block 52 is provided with limiting blocks 521, which are slidably connected to the sliding grooves 121 symmetrically opened in the middle of the front and rear sides of the cavity 12.

[0031] There are two drive wheel seats 6, which are symmetrically fixed on the outer wall of the rear end plane of the traction machine body 1. Each drive wheel seat 6 is equipped with an electric wheel 7, and the electric wheel 7 is equipped with a rubber ring 71. The rear end of the traction machine body 1 is provided with a cavity 3 15, and a storage battery 8 is installed in the cavity 3 15. The storage battery 8 is electrically connected to the drive wheel seat 6.

[0032] The working principle of this utility model is as follows:

[0033] Initial cable fixing: After inserting the cable into the cavity 12 through the external threaded tube 11, rotate the clamping sleeve 4 clockwise. The clamping sleeve 4 moves closer to the traction machine body 1. At the same time, the elastic locking plates 421 on both sides inside the clamping sleeve 4 move closer to the central axis of the external threaded tube 11. During the rotation of the clamping sleeve 4, the front end of the elastic locking plate 421 is gradually squeezed by the inner wall of the external threaded tube 11. When the clamping sleeve 4 can no longer rotate, the rear end of the elastic locking plate 421 is squeezed and plastically deformed, firmly clamping the cable.

[0034] Secondary cable fixing: Rotate the threaded rods 5 on both sides of the traction machine body 1 clockwise. Under the limiting action of the limiting block 521 and the slide groove 121, the clamping block 52 moves along the slide groove 121 toward the outer wall of the external threaded tube 11 inside the cavity 12 until the clamping block 52 firmly clamps the cable, and then stop rotating the threaded rod 5.

[0035] Traction cable: Place the traction machine body 1 with the cable fixed into the beginning of the pipe (the size of the traction machine body 1 depends on the pipe diameter), make the pulley 3 on the traction machine body 1 and the electric wheel 7 close to the inner wall of the pipe, and then start the electric wheel 7 to drive the traction machine body 1 to move towards the end of the pipe until the cable is completely through the pipe.

[0036] With the cooperation of the clamping sleeve 4 and the clamping block 52, the cable can be fixed without the need for tools, preventing the cable sheath from being worn. This facilitates the fixing of the cable and improves work efficiency. The device has a simple structure, small size, is easy to carry, and is economical and practical.
