Description

Technical Field

[0001] This utility model relates to a novel underground cable suspension device. Background Technology

[0002] In the traditional installation process of integrated equipment, manual hanging of cables is required. This process often involves working at heights. In recent years, due to the improvement of equipment efficiency, the size of power supply cables has generally increased, and they are heavy. This requires the cooperation of many people, making the construction difficult and a weak link in the safety of installation and removal operations.

[0003] Chinese utility model patent CN218958413U, authorized on May 2, 2023, discloses an underground high-voltage cable suspension device. This device includes a support rod and a rubber-tired mine car. The mine car has a front idler roller on its front end and one or two uprights on its side. A U-shaped idler roller frame is located at the top of each upright, and two horizontal idler rollers are mounted on the U-shaped idler roller frame. Each horizontal idler roller includes a roller shaft and a roller sleeve fitted onto the roller shaft. The underground high-voltage cable to be installed passes over the front idler roller and then passes between the two horizontal idler rollers at the top of the uprights. The column includes an inner tube and an outer tube. The lower end of the outer tube is fixed to the rubber-tired mine car. Multiple opposite pin holes are opened on both sides of its outer wall from top to bottom. The lower part of the inner tube is inserted into the outer tube. One or two opposite pin holes are opened on both sides of its outer wall. The pin hole of the inner tube can be selected to be opposite to the pin hole on the outer tube, and a pin is inserted through them to fix the column at different heights. The U-shaped idler roller frame is fixed to the top of the column.

[0004] The height of the column of this utility model can only be roughly adjusted, and its position and angle cannot be adjusted. It is inconvenient to adjust when encountering bends or complex terrain. Moreover, its U-shaped roller frame only has horizontal rollers. When in use, the inner wall of the U-shaped roller frame will still slide and rub against the underground high-voltage cable to be installed. The frictional resistance is large, the column cannot be mechanically raised and lowered, and the U-shaped roller frame cannot be placed on the roadway floor. When installing underground high-voltage cables, it is necessary to manually lift the heavy cable and lift it into the U-shaped roller frame, which is labor-intensive. Summary of the Invention

[0005] The technical problem to be solved by this utility model is how to overcome the above-mentioned defects of the prior art and provide a new type of underground cable hanging device.

[0006] To solve the above-mentioned technical problems, this novel underground cable suspension device includes a mine car and a support rod. Its features include: the mine car is a tracked single-arm crane, which includes a tracked traveling platform, a rotating platform, and a telescopic lifting arm. The rotating platform is mounted on the tracked traveling platform, and the root of the telescopic lifting arm is hinged to the rotating platform. A front lug is provided on the rotating platform, and a lower lug is provided at the bottom of the telescopic lifting arm. A hydraulic telescopic cylinder is provided between the front and lower lugs. A cable guide frame is connected to the front end of the telescopic lifting arm. The cable guide frame includes a top beam, an upper horizontal roller, a lower horizontal roller, a left vertical roller, a right vertical roller, two upper fixing blocks, and two lower fixing blocks. The upper horizontal roller includes an upper horizontal shaft and an upper roller cylinder; the lower horizontal roller includes a lower horizontal shaft and a lower roller cylinder; the left vertical roller includes a left vertical shaft and a left roller cylinder; and the right vertical roller includes... The top beam has connecting plates at both ends, and two upper fixing blocks are fixed to the inner side of the connecting plates. Two lower fixing blocks are respectively set below the two upper fixing blocks. The upper and lower fixing blocks on the same side have corresponding vertical through holes. The left and right vertical shafts pass through and are fixed in the vertical through holes of the upper and lower fixing blocks. The left and right rollers are rotatably sleeved on the left and right vertical shafts. The two upper fixing blocks have corresponding horizontal through holes. The two ends of the upper horizontal shaft pass through and are fixed in the horizontal through holes of the upper fixing blocks. The two lower fixing blocks have corresponding horizontal through holes. The two ends of the lower horizontal shaft pass through and are fixed in the horizontal through holes of the lower fixing blocks. The upper and lower rollers are rotatably sleeved on the upper and lower horizontal shafts. The cable to be installed passes through the upper and lower horizontal rollers and the left and right vertical rollers.

[0007] This design allows the cable guide frame to be lowered onto the tunnel floor by adjusting the rotary table, controlling the telescopic boom, and manipulating the hydraulic cylinder before use. The cable to be installed is then threaded through the cable guide frame, or the lower horizontal roller can be removed, the cable placed in the guide frame, and then the roller reset. Adjusting the rotary table, telescopic boom, and hydraulic cylinder raises the cable guide frame to a suitable position close to the tunnel sidewall. Moving the tracked single-arm crane, along with the support rod, allows the cable to be easily lifted to the appropriate position on the tunnel sidewall for convenient installation. At corners or other complex terrain, adjusting the telescopic boom and hydraulic cylinder ensures the cable guide frame remains close to the tunnel sidewall, saving effort, providing convenience, and offering greater adaptability.

[0008] As an optimization, a fixing ring is provided in the middle of the top beam, and a connecting ring is connected to the fixing ring. The connecting ring is composed of a C-shaped ring with opposing through holes at both ends and bolts passing through the through holes. The cable guide frame is fixed to the front end of the telescopic lifting boom through the connecting ring. This design makes fixing convenient.

[0009] As an optimization, there are two left and two right vertical rollers, and the upper and lower horizontal shafts and the left and right vertical shafts are all constructed with bolts. This design results in a symmetrical cable guide frame structure and convenient installation.

[0010] This new type of underground cable hanging device has a simple structure, saves effort, is convenient, and has greater adaptability, making it suitable for the installation and laying of underground high-voltage cables. Attached Figure Description
