Description

Technical Field

[0001] The present invention relates to the technical field of cable laying and traction, and in particular to a power cable laying and traction device and method which can adapt to complex terrain. Background Art

[0002] Specifications for laying cables for power projects. When selecting wires and cables, attention should be paid to the selection of wire and cable models and specifications. When selecting wire and cable models, the purpose, laying conditions and safety should be considered. According to different purposes, power cables, overhead insulated cables, control cables, etc. can be selected. According to different laying conditions, general plastic insulated cables, steel belt armored cables, steel wire armored cables, anti-corrosion cables, etc. can be selected. Cable laying refers to the process of laying and installing cables along the surveyed routes to form cable lines. According to the occasions of use, it can be divided into overhead, underground, underwater, wall and There are several laying methods, such as tunnels, etc. Reasonable selection of cable laying methods is very important to ensure the transmission quality, reliability and construction and maintenance of the line. Long-distance communication cables are generally laid in direct burial to ensure safe and reliable communication. Urban trunk cables are generally laid in pipelines to ensure safe and reliable communication, convenient installation and replacement, and beautiful appearance. Urban wiring cables can be laid overhead and on the wall. With the development of modern urban construction, they will gradually be replaced by pipeline laying. Cable laying often requires the winding computer to adapt to the stable unwinding and traction operation.

[0003] For example, the patent document with the announcement number CN 219058199 U discloses a movable cable laying traction rope retracting device. The utility model includes a moving part, a connecting part fixedly connected to the moving part, a traction rope retracting part connected to the moving part, and a traction rope wound around the traction rope retracting part and rotatable around the traction rope retracting part. The utility model is simple to operate, convenient to transport, and very portable. It has strong adaptability to places such as complex terrain, poor roads, and field construction. It greatly improves the construction efficiency and quality when constructing power facilities and repairing power cables, and also saves transportation time and manpower. The utility model also reduces the overturning risk factor of the heavy cable traction rope laying device in the prior art during transportation in complex terrain, effectively avoiding the occurrence of unsafe accidents of knocking down people and equipment.

[0004] However, during the actual use of this structure, due to the limitations of its own structure, it can often only support and install the cable laying traction rope retracting and releasing device on a simple flat ground as a whole, and then perform the operation of retracting and releasing the traction rope. However, the actual power cable laying environment is often an uneven ground. Especially for the power cable laying work in mountainous areas, it is impossible to perform the support installation operation that makes the whole device more adaptable to the inclined ground on complex terrains, so it is impossible to carry out the power cable laying traction work on complex terrains. At the same time, when the device is used for power cable laying traction on complex terrains, during the wire releasing process, it is impossible to ensure the continuous unwinding and limiting operation of the traction rope to be more uniform and stable, which cannot meet the daily use requirements. Therefore, it is urgent to design a power cable laying traction device and method that can adapt to complex terrains to solve the above problems. Summary of the Invention

[0037] Working principle: When in use, the operator first moves the entire connection box frame 1 to the designated traction position for laying power cables. Then, the sliding seats 40 and the third fixing bolts 41 on the sides of the first track frame 2 and the second track frame 3 are adjusted to slide up and down along the internal limiting chute 39. This enables the second telescopic struts 42 inside the first track frame 2 and the second track frame 3 to be adjusted to lower positions. After adjusting to the appropriate height, the third fixing bolts 41 on the sides of the sliding seats 40 can be tightened to fix the second telescopic struts 42 inside the first track frame 2, preliminarily performing the overhead installation operation between the entire connection box frame 1 and the complex terrain. Then, the rotating side tubes 5 inside the adjusting side frames 4 on both sides of the first track frame 2 and the second track frame 3 are adjusted to be inclined along the first adjusting shafts 31 at their respective tops. The adjustment angle can be dampingly adjusted through the second adjusting shaft 35, the damping diagonal tie rod 37, and the third adjusting shaft 38 inside the adjusting side frames 4. After adjusting to the appropriate position, the second fixing bolts 36 at the bottom of one side of the adjusting side frames 4 can be tightened for fixation to achieve the locking operation of the rotating side tubes 5. After that, by pulling the first telescopic struts 33 inside the rotating side tubes 5, the anti-slip foot seats 34 at the bottom are made to support and abut against the ground of the complex terrain, thus realizing a more stable adaptation and reinforcement support operation at the four corners of the connection box frame 1. At the same time, in daily use, the first air control pump 7 on the back of the storage rack 6 can be started to inflate and expand the expansion airbag 8 inside the storage rack 6. This causes the expansion airbag 8 to drive the entire support bottom frame 29 at the bottom to expand upwards, enabling the support soft sleeve 30 of the support bottom frame 29 to support and abut against the ground of the complex terrain for the support and reinforcement operation at the central position. After the installation is completed, the first side plate 11, the cable reel 12, and the second side plate 13 can be integrally placed on the docking frame 9 at the tops of the first track frame 2 and the second track frame 3 through the docking seats 10 at both ends. At this time, the insertion blocks 27 of the docking seats 10 are inserted into the internal insertion slots 28 of the docking frame 9, quickly assembling and using the cable laying traction rope, greatly improving the stability of the subsequent cable laying and traction use of the entire connection box frame 1. During daily use, the operator can wind the cable laying traction rope around the cable reel 12 between the first side plate 11 and the second side plate 13, and fit the socket ring frame 14 onto the rope coil. The rope end is passed through the rope passing holes 17 of the shrinkage ring cover 15 and the universal rolling ball 16 at the top of the socket ring frame 14. When the cable reel 12 rotates and pays out the cable through the rotating shaft seats 23 at both ends during daily use, the inner wall of the first side plate 11 and the second side plate 13 is provided with the disk-shaped grooves 24, and the two ends of the rope coil are limited by the annular rubber seats 25 and the abutting rubber rings 26. And in daily use, the second air control pump 18 at the bottom of the socket ring frame 14 can be started to inflate the two-sided shrinkage arc covers 19, so that the arc-shaped airbags 20 inside the shrinkage arc covers 19 fit against the bottom of the rope coil.The air guide side pipe 21 on the side of the socket ring frame 14 can also inflate the top contraction ring cover 15, always pressing the airbag pipe 22 inside the contraction ring cover 15 against the rope coil, performing the top traction and guiding wire laying operation and the guiding traction operation. At the same time, usually, the limit pulley 44 and the series rope 45 inside the connection box frame 1 can be successively passed out from the limit socket 43, and then the daily guiding and conveying operation of the traction rope for power cable laying can be carried out. The above is the whole working principle of the present invention.

[0038] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present invention.

The adjustment angle is damped through the second adjusting shaft (35), the damping inclined pull rod (37), and the third adjusting shaft (38) inside the adjusting side frame (4). After adjusting to a suitable position, turn the second fixing bolt (36) at the bottom end of one side of the adjusting side frame (4) for fixing to achieve the locking operation of the rotating side tube (5); S2. Fit the socket ring frame (14) onto the rope reel. Thread the rope head through the rope passing holes (17) of the top contraction ring cover (15) and the universal rolling balls (16) of the socket ring frame (14). When the daily winding and unwinding roller (12) rotates and pays out the wire through the rotating shaft seats (23) at both ends, at the disc-shaped grooves (24) on the inner walls of the first side disc (11) and the second side disc (13), limit the two ends of the rope reel through the annular rubber seats (25) and the top contact rubber rings (26). And normally start the second air control pump (18) at the bottom end of the socket ring frame (14) to inflate the inside of the two-side contraction arc covers (19), so that the arc-shaped air bags (20) inside the contraction arc covers (19) fit the bottom of the rope reel. The air guiding side tubes (21) on the side of the socket ring frame (14) can also inflate the top contraction ring cover (15), and always press the air bag tube (22) inside the contraction ring cover (15) against the rope reel.
