Description

Technical Field

[0001] The present invention relates to the technical field of cable traction, and specifically to a traction laying device for installing power cables. Background Art

[0002] Power cables refer to cables used for transmitting and distributing electric energy. They play a crucial role in the power system, transporting electric energy from power plants to user ends. Power cables usually consist of conductors, insulating layers, shielding layers, and protective layers.

[0003] In urban areas, most cable installation methods are underground installation methods. Generally, underground pipelines need to be buried in advance underground, and then one end of the cable to be installed is fixed by a rope. Then, the rope is pulled manually, so that the power cable can be installed in the underground pipeline. When the cable is towed to the appropriate position, other cables are then connected and installed.

[0004] By searching, it is found that CN222365998U discloses a power cable installation traction device, belonging to the technical field of cable traction, including a box body. A collar is fixedly arranged on one side surface of the box body. The inner cavity of the collar is hollowed out. A circular groove is opened in the inner cavity of the collar. A limiting plate is fixedly installed on one inner wall of the circular groove. A matching disk is slidably arranged in the inner cavity of the collar. The inner cavity of the disk is hollowed out. Teeth are installed on the circumferential side of the disk. A sliding groove adapted to the limiting plate is opened on one side surface of the disk. A brush for cleaning the surface of the power cable is installed in the inner cavity of the disk. This power cable installation traction device solves the problem that dust and stone particles adhering to the periphery of the power cable will cause slipping, and improves the efficiency of laying the power cable.

[0005] However, the problems encountered in actual applications are: due to the narrow space of underground pipelines, the devices in the prior art are not convenient to enter the underground pipelines for work. There is still a large frictional force between the power cable and the inner wall of the underground pipeline. At this time, it is more laborious and inconvenient to install the cable by manual traction. Moreover, water stains and sand may adhere to the surface of the cable, and manual pulling of the power cable will still cause slipping. Therefore, we propose a traction laying device for installing power cables. Summary of the Invention

[0018] Beneficial effects

[0019] The present invention provides a device for installing, towing and laying power cables, and has the following beneficial effects:

[0020] 1. For this device for installing, towing and laying power cables, by setting a six-claw traveling mechanism, by adjusting the distance between the two fixed rings, the six claw rods can be opened or closed, so that the moving wheels can contact the inner wall of the underground pipeline, and it can adapt to underground pipelines with different diameters, improving the applicability. The rotation of the moving wheels can drive the whole device to move in the underground pipeline. When the device moves to a suitable position, the power cable can be supported by the two fixed rings, so that a part of the power cable can be suspended in the underground pipeline, and the combined use of multiple devices can increase the suspended area, thus greatly reducing the friction between the power cable and the inner wall of the underground pipeline, facilitating the manual towing and laying of the power cable by the staff, effectively saving physical strength and improving the laying efficiency.

[0021] 2. For this device for installing, towing and laying power cables, by setting a cable cleaning mechanism and a number of bristles, when the staff tow the power cable to move, the bristles contact the power cable to initially clean the sand on the surface of the power cable. The rotation of the driving gear can drive the rotation of the annular cleaning brush, so as to clean the sand on the surface of the power cable in all directions. With the hot air blown in through a plurality of hot air holes, the water stains on the surface of the power cable can be dried, thus effectively avoiding the slipping phenomenon when pulling the power cable.

[0022] 3. The power cable installation traction and laying device can facilitate the opening of the housing to repair and clean the interior of the housing by setting a maintenance door. By setting limit protrusions, anti-fooling grooves and screws, the annular cleaning brush can be conveniently disassembled, replaced and cleaned.

[0023] 4. The power cable installation traction and laying device can fix the whole device in the underground pipeline by setting a cable auxiliary traction mechanism and an electric telescopic rod. When the electric telescopic rod extends and the movable end of the electric telescopic rod presses against the inner wall of the underground pipeline. By driving the second bidirectional lead screw to rotate by the second servo motor and cooperating with the limit slide rod to limit the movable plate, the distance between the two pairs of movable plates can be adjusted so that the two anti-slip wheels can press against both sides of the outer surface of the power cable. Finally, by driving the anti-slip wheels to rotate by the drive motor, a force towards the cable laying direction can be applied to the power cable, so that the installation and laying work of the power cable can be carried out more labor-saving. Moreover, the labor-saving effect of this device is particularly obvious when installing and laying power cables in long underground pipelines and underground pipelines with a certain degree of curvature.

Moreover, the device is particularly labor-saving when installing and laying power cables in long underground pipelines and underground pipelines with a certain curvature.

[0048] Working principle: When the traction and laying device for the power cable is in use, first place the entire device into the underground pipeline. Then, fix and tie the rope to the device, and through the external remote control terminal, control the entire device to move from one end of the pipeline to the other end, so that the rope can pass through the entire underground pipeline. Then, fix and tie the end of the rope to the power cable, and pull the rope from the other end to make the power cable pass through the annular bin 2, the fixing ring 13, and the annular cleaning brush 12 in sequence. When installing and laying the power cable, the entire device can be controlled to move to the middle or the turning point of the underground pipeline through the external remote control terminal. By extending the electric telescopic rod 35, the entire device can be fixed on the inner wall of the underground pipeline. At this time, by manual or mechanical traction method to pull the rope, the power cable can be driven to move. When the power cable passes through the annular bin 2, the fixing ring 13, and the annular cleaning brush 12 in sequence, the sandy soil on the surface of the power cable can be initially cleaned by the contact between the bristles 5 and the power cable.
