Description

Technical Field

[0001] The utility model relates to the technical field of cable recovery, and specifically relates to a TBM high-voltage cable recovery device. Background Art

[0002] TBM high-voltage cable is a type of cable in tunnel boring machine (TBM) equipment, mainly used to transmit the high-voltage power supply required by TBM mechanical equipment. TBM high-voltage cable is generally 3.3kV or 6kV, which can provide sufficient power to meet the needs of TBM equipment. TBM high-voltage cable is usually made of special waterproof, pressure-resistant, wear-resistant and other materials to ensure its working quality under harsh conditions. TBM high-voltage cable is an indispensable key component in the TBM tunnel excavation process.

[0003] During the use of TBM high-voltage cables, they need to move forward continuously with the tunnel boring machine (TBM), so they need to be reeled in and recovered in time. The existing reel is not convenient for transportation, and the risk factor of pulling the reel by truck is relatively high, and it is not convenient to operate in the tunnel. Secondly, improper reeling can easily lead to cable disconnection or short circuit and other faults, which will affect the normal use of TBM. Therefore, we propose a TBM high-voltage cable recovery device to ensure the subsequent normal operation of TBM. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a TBM high-voltage cable recovery device, comprising a roller frame, a bottom plate is provided on the lower surface of the roller frame, a fixed structure is symmetrically fixedly connected to the upper surface of the bottom plate, the bottom plate is connected to the roller frame through the fixed structure, a wheel frame is fixedly connected to the lower surface of the bottom plate, a track wheel is installed in the inner cavity of the wheel frame, a rotating shaft is installed at the center of the inner wall of the roller frame, a roller is provided on the outer wall of the rotating shaft, a groove is provided on the outer wall of the roller, a circular plate is symmetrically fixedly connected to the side wall of the roller, and the other side of the circular plate is gap-matched with the inner wall of the roller frame.

[0006] Preferably, the fixing structure includes two strip plates, the lower surface of the strip plates is fixedly connected to the upper surface of the bottom plate, the inner walls of the two strip plates fit with the side walls of the roller frame, the upper surface of the strip plates is fixedly connected with a screw, the outer wall of the screw is sleeved with a circular hole plate, the lower surface of the circular hole plate fits with the upper surface of the strip plates, the side wall of the circular hole plate is fixedly connected to the side wall of the roller frame, the outer wall of the screw is threadedly connected with a nut, and the lower surface of the nut fits with the upper surface of the circular hole plate.

[0007] Preferably, a top hanging ring is symmetrically fixedly connected to the upper surface of the rotating roller frame, and a side hanging ring is symmetrically fixedly connected to the side wall of the rotating roller frame.

[0008] Compared with the prior art, the utility model has the following beneficial effects: the side wall of the roller has a groove, which can fit the cable to facilitate cable winding. At the same time, circular plates are arranged on both sides for shielding. The circular plates are designed to be large in size and can wrap the TBM high-voltage cable around the outer wall of the roller to prevent the TBM high-voltage cable from being entangled in the gap during winding. While ensuring the safety of the TBM high-voltage cable, an orderly winding process is carried out to reduce wear and tear to extend the service life of the cable. After winding, the roller frame is used to shield and store the cable, making maintenance and management more convenient, reducing damage to the cable during work, and making the TBM work safer and more reliable. The use of track wheels at the bottom also facilitates movement in the tunnel, which helps to improve the use efficiency and working performance of the TBM and ensure the quality, service life and working safety of the cable.

[0016] Before reeling in the TBM high-voltage cable, the high-voltage power supply must be turned off first. This is to ensure the safety of the staff and prevent the cable from being electrocuted. The connection between the TBM high-voltage cable and the TBM machine is disconnected. The roller 5 can be rotated by the shaft 4. The protruding position of the shaft 4 can be connected to the transmission equipment. During the reeling process, attention should be paid to the tension of the cable and the cable should be prevented from being subjected to excessive tension, so that the roller 5 can be rotated smoothly for reeling.
