[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-2 The utility model discloses a random cable dragging device for a tunnel boring machine, comprising a steel wire rope and a hook device 1. The steel wire rope is suspended at the top of the tunnel boring machine in the forward direction. The hook device 1 is used to be detachably hung on the steel wire rope. A connection box 3 is installed on the hook device 1. A cable hanging frame 9 is detachably installed at the bottom of the connection box 3. The cable hanging frame 9 is used to be sleeved on the random cable. When in use, multiple devices are installed on the steel wire rope at corresponding intervals, and the random cable passes through the cable hanging frames 9 in multiple devices, so that the random cable is suspended at the bottom of the steel wire rope.

[0023] In one embodiment, the device also includes a telescopic device, which can be slidably and vertically inserted into the connection box 3. The telescopic device has two upper and lower telescopic ends. The telescopic end at the top of the telescopic device and the inner top wall of the hook device 1 are both rotatably installed with a pulley 8, and the telescopic end at the bottom of the telescopic device and the inner bottom wall of the cable hanging frame 9 are both installed with a fixed column 10. The two telescopic ends of the telescopic device are extended at the same time to make the corresponding pulley 8 and the fixed column 10 approach or move away from the other pulley 8 and the fixed column 10.

[0024] When the wire rope and the random cable pass through the hook device 1 and the cable hanging frame 9 in the device respectively, the telescopic device is controlled to extend its two telescopic ends, thereby driving the pulleys 8 and the fixed column 10 on the two telescopic ends of the telescopic device to approach the other pulley 8 and the fixed column 10 until they contact the wire rope and the random cable. When the corresponding pulley 8 or the fixed column 10 first contacts the wire rope or the random cable, the two telescopic ends of the telescopic device continue to extend, and the telescopic end of the telescopic device that is resisted will push the other telescopic end in the opposite direction to move at a faster speed, so that the pulley 8 or the fixed column 10 on the other telescopic end quickly contacts the wire rope or the random cable, and the wire rope contacts the pulley 8 in the device, so that the device can move on the wire rope, and the random cable is clamped by the corresponding fixed column 10, so that it can be installed on the device very stably. When the tunneling machine moves forward, the random cable will move synchronously. At this time, the cable slide formed by the wire rope and multiple devices can make the random cable very stably and efficiently towed safely with the tunneling machine.

[0025] It can be understood that the pulleys 8 and the fixed columns 10 on the two telescopic ends of the telescopic device are close to the other pulleys 8 and the fixed columns 10, which enables the device to be adaptively installed and used for steel wire ropes and random cables of different sizes, thereby improving the applicability of the device.

[0026] In one embodiment, the hook device 1 includes a first frame 11 and a second frame 12 hingedly arranged on the first frame 11. A fixing member 2 is installed on the side of the first frame 11 and the second frame 12 away from the hinge point. The fixing member 2 can be used in combination with a bolt and a nut. The connecting box 3 is installed on the first frame 11.

[0027] With this design, when the fixing member 2 is removed, the second frame 12 can be rotated open from the hinge point, so as to facilitate the installation of the hook device 1 on the wire rope. After the installation is completed, the fixing member 2 is installed on the side of the first frame 11 and the second frame 12 away from the hinge point, so that the hook device 1 can be installed on the wire rope very stably and cannot be easily detached.

[0028] In one embodiment, a through hole 13 is formed on the second frame 12, and the through hole 13 is used to cooperate with the bolt to fix the hook device 1 on the frame of the tunnel boring machine.

[0029] Such a design allows the random cables extending from the electric control box at the rear of the tunnel boring machine to first pass through the device fixed on the frame of the tunnel boring machine, so that the random cables at the tunnel boring machine can be stably limited.

[0030] In one embodiment, a mounting groove 4 is provided inside the connection box 3 and is arranged along the height direction of the connection box 3. The telescopic device can be slidably inserted in the mounting groove 4. The telescopic device includes two sliders 5 slidably installed in the mounting groove 4, a lead screw 6 inserted in the two sliders 5 and cooperating therewith, and a knob 7 installed on the top of the lead screw 6. The lead screw 6 is provided with two sections of threads in opposite states. A U-shaped frame is installed on the top slider 5, one of the pulleys 8 is installed on the U-shaped frame, and one of the fixed columns 10 is installed on the bottom slider 5.

[0031] In the specific implementation, the staff holds the knob 7 and rotates it to adjust it, so that the screw 6 rotates and drives the two sliders 5 to move closer to or away from each other, so that the corresponding pulley 8 and the fixed column 10 move synchronously and move closer to or away from the other pulley 8 and the fixed column 10. The setting of the U-shaped frame can not only facilitate the installation and use of the pulley 8, but also enable the staff to drive the screw 6 to rotate and adjust the connection box 3 through the knob 7. In actual use, a strip-shaped limiting groove (not shown in the figure) arranged along the height direction of the connection box 3 can be opened on the opposite side walls of the connection box 3. The limiting groove is connected to the installation groove 4, and limiting plates (not shown in the figure) extending into the limiting groove are installed on the outer walls of both sides of the two sliders 5. With this design, when the two sliders 5 are slid and adjusted, since the limiting plates always move in the limiting grooves, the two sliders 5 can be prevented from separating from the connection box 3, so as to ensure the safety of the adjustment of the device.

[0032] In one embodiment, the cable hanging frame 9 includes a base 91 and an arc frame 92 with one end hingedly arranged on both sides of the base 91, the other ends of the two arc frames 92 are installed on the connection box 3 by bolts, and the corresponding fixing column 10 is arranged on the top of the base 91.

[0033] With such a design, when the bolts at the connection between one of the arc-shaped frames 92 and the connection box 3 are removed, the arc-shaped frame 92 can be rotated open, thereby facilitating the installation of the cable hanging frame 9 onto the random cables.

[0034] In one embodiment, an anti-scratch layer is installed on the pulley 8 and the fixing column 10, and the anti-scratch layer can be a rubber layer.

[0035] With such a design, when the pulley 8 and the fixing column 10 are in continuous contact with the steel wire rope and the random cable, the provision of the anti-scratch layer can prevent the joints thereof from rubbing against each other and causing damage to the surfaces of the steel wire rope and the random cable.
