[0002] A cable is a collection of conductors composed of one or more insulated conductors for transmitting electrical energy. It is mainly used to transmit electricity or signals. The structure of a cable usually includes a conductor, an insulation layer, a sheath and other parts. The conductor is used to transmit current, the insulation layer is used to prevent current leakage, and the sheath is used to protect the cable from the influence of the external environment. During the coal cutting process of the tunnel boring machine, the cable transport device usually refers to a device specially designed to drag, protect and manage the cable during the operation of the tunnel boring machine. Since the tunnel boring machine needs to move along the tunnel when cutting coal, and the cable needs to provide power or signal transmission for the tunnel boring machine, the role of the cable transport device is particularly important.

[0003] During coal cutting, the existing tunnel boring machine's cables will fall to the ground and cannot be hung, and a dedicated person must be arranged to look after the secondary transport cables. During the process of the cables falling to the ground and moving, the cables may be affected by external forces such as friction and extrusion, and then suffer from problems such as wear, deformation or breakage. This will not only affect the service life and performance of the cables, but may also have an adverse impact on related power or communication systems.

[0004] Therefore, in view of the fact that the cables of the above-mentioned existing tunnel boring machines will fall to the ground during coal cutting and cannot be hung, which may cause problems such as wear, deformation or breakage of the cables, which will not only affect the service life and performance of the cables, but also have an adverse effect on the power or communication systems, a cable transportation device that can flexibly move the cables can be designed, and a movable limit structure can be set on the outside of the cables, so that they can be flexibly moved while being hung.

[0023] See also Figure 2 106 , which is a set of holes 106 on both sides of the square telescopic column 105 .

[0024] See also Figure 3 In this embodiment, the cable is fixed on the lockless buckle 202, so that when the tunnel boring machine moves forward and backward, the oil rope 201 drives the lockless buckle 202 to move along the pulley block 204, thereby driving the cable to automatically retract and retract.

[0025] See also Figure 4In this embodiment, the receiving assembly includes a rectangular telescopic sleeve 301, a rectangular telescopic plate 302, a fixing pin 303, a fixing hole 304 and a plug hole 305. A rectangular telescopic plate 302 is provided inside each of the two sides of the rectangular telescopic sleeve 301. The rectangular telescopic plate 302 is away from the end of the rectangular telescopic sleeve 301 and has a plug hole 305 corresponding to the plug column 103. Pick up the rectangular telescopic plate 302, and the rectangular telescopic plate 302 passes through the plug hole 305 and is positioned and connected to the square telescopic sleeve 1. The rectangular telescopic plate 302 is connected to the rectangular telescopic sleeve 301. Fixed pins 303 are symmetrically provided on both sides of the joint, and multiple groups of fixing holes 304 are symmetrically opened on both sides of the rectangular telescopic plate 302. According to the installation position distance of the two groups of square telescopic sleeves 1, the rectangular telescopic plate 302 is moved laterally to a suitable length along the rectangular telescopic sleeve 301 by adjusting the fixed pins 303. The fixed pins 303 pass through the rectangular telescopic sleeve 301 and are positioned and connected to the rectangular telescopic plate 302 through the fixing holes 304. After confirming that the connection is correct, the fixed pins 303 pass through the rectangular telescopic sleeve 301 and are positioned and connected to the rectangular telescopic plate 302 through the fixing holes 304. After confirming that the connection is correct, the fixed pins 303 are passed through the rectangular telescopic sleeve 301 and are positioned and connected to the rectangular telescopic plate 302.

[0026] During operation, first screw through the mounting hole 102 to fix the square mounting plate 101 to the second transport head of the tunnel boring machine and the dust removal fan respectively.
