[0019] 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.

[0020] See also Figure 1-Figure 3 .

[0021] The utility model discloses a semi-automatic cable dragging device, comprising a guide rail 1 suspended in the air and a plurality of rolling racks 2 rollingly arranged on the guide rail 1, wherein the rolling racks 2 are arranged at intervals, a clamping component 3 is arranged at the bottom end of each rolling rack 2, and the cable passes through each clamping component 3 and is clamped by the clamping component 3 and suspended at the bottom of the guide rail 1.

[0022] In the specific implementation, the guide rail 1 is connected to the top of the tunnel under construction in the mine by a flexible iron chain or a rigid steel bar, so that the guide rail 1 is suspended in the air (the support anchor rod at the top of the tunnel can also be used to fix the guide rail 1 to the top of the tunnel). The cable passes through each clamping component 3 and is clamped and suspended at the bottom of the guide rail 1 by the clamping component 3. One end of the cable is connected to the tunnel boring machine. When the tunnel boring machine moves forward, it drags the cable forward. The cable is subjected to the forward force and drives the corresponding rolling frame 2 to move on the guide rail 1, realizing the automatic movement of the cable. At the same time, because the cable is suspended between the rolling frames 2, under the action of the gravity of the cable, the cable between the rolling frames 2 will be subjected to a falling force. When the tunnel boring machine moves backward, this falling force will automatically drive the cable to move backward. Since in actual operation, the distance that the tunnel boring machine moves backward is very short, the distance that the cable moves backward by the falling force is sufficient to cooperate with the work of the tunnel boring machine (if necessary, it can be coordinated with manual dragging backward, saving time and effort).

[0023] The present application greatly reduces the impact of the complex construction environment of the mine on the cable movement by hanging the cable, and the cable is not easily scratched. The rolling frame 2 rollingly arranged on the guide rail 1 can move forward with the advancement of the cable. At the same time, under the action of the gravity of the cable, when the tunnel boring machine moves backward, it will automatically drive the cable to retract backward to cooperate with the work of the tunnel boring machine.

[0024] It should be pointed out that the specific structure and style of the clamping component 3 are common knowledge to those skilled in the art, and can be any product available on the market that can be fixed to a cable, so no further details will be given here. A pipe clamp may also be used.

[0025] In one embodiment, the guide rail 1 is a round tube, specifically a steel tube. With this design, the steel tube is used as the guide rail 1, which has a simple structure and is durable. Compared with the guide rail 1 in the form of a traditional chute slider, it is not afraid of the dusty working environment during coal cutting of the tunneling machine, and has stronger adaptability. Even if an object falls from the top of the tunnel during coal cutting and hits the steel tube, causing a certain degree of deformation of the steel tube, it will still not affect the normal use of the equipment, and has strong adaptability.

[0026] In one embodiment, the rolling frame 2 and the clamping member 3 are flexibly suspended below the rolling frame 2 via a first flexible member 4 .

[0027] In a specific implementation, the first flexible component 4 is a chain, a rope, etc. The clamping component 3 flexibly suspended below the rolling frame 2 can reduce the forces (such as torsional forces) in other directions on the guide rail 1 on the one hand, and on the other hand, it is also convenient to drive the rolling frame 2 to move on the guide rail 1.

[0028] In one embodiment, the rolling frame 2 includes a frame body 21 with an opening at the top and through two sides, and the guide rail 1 passes through the frame body 21 from the opening. At least one group of roller groups 22 are arranged on the frame body 21. The roller group 22 is located in the opening of the frame body 21 and located in the middle and upper part of the guide rail 1. The roller group 22 includes rollers rotatably arranged on both sides of the frame body 21, and the rollers are in rolling cooperation with the guide rail 1.

[0029] More specifically, there is a gap between the rollers on both sides of the frame 21, and the guide rail 1 is provided with a connecting plate 11 at the corresponding gap, and the guide rail 1 is connected to the installation point through the connecting plate 11, so that the guide rail 1 is suspended in the air. This design not only enhances the connection reliability of the guide rail 1, but also does not affect the normal movement of the rolling frame 2 on the guide rail 1.

[0030] In one embodiment, a second flexible component is further provided between the guide rail 1 and the installation point, and the guide rail 1 is suspended in the air by the second flexible component.

[0031] In a specific implementation, the second flexible component is a chain, a rope, etc., one end of the second flexible component is connected to the connecting plate 11, and the other end is connected to the support anchor rod at the top of the tunnel. When the tunnel boring machine turns during its travel, the guide rail 1 can automatically deflect an angle under the action of the drag force, so that the guide rail 1 is always in the same straight line with the tunnel boring machine, which can further reduce the forces in other directions on the guide rail 1, ensure that the maximum force on the guide rail 1 is a vertical force, ensure that the force direction of the guide rail 1 does not change significantly, and ensure the connection reliability of the guide rail 1.

[0032] In one embodiment, an elastic telescopic component 5 is provided between two adjacent rolling frames 2. With this design, the elastic telescopic component 5 enables the front rolling frame 2 to drive the rear rolling frame 2 to move on the guide rail 1, so that the intervals between the rolling frames 2 are roughly equal, and the cable can move a greater distance when it moves backward.

[0033] In one embodiment, the elastic telescopic component 5 includes a first rod 51, and the two ends of the first rod 51 are slidably sleeved with a second rod 52, and a spring 53 is provided between the first rod 51 and the second rod 52, and the spring 53 is used to push the second rod 52 to slide on the first rod 51 in a direction close to the first rod 51, and the second rod 52 is rotatably connected to the corresponding rolling frame 2. With this design, since the minimum distance between the first rod 51 and the second rod 52 remains unchanged, the elastic telescopic component 5 of this structure can also maintain the minimum spacing between the rolling frames 2 while maintaining the original function, so as to prevent the cable from being entangled.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

[0035] It should be noted that if the embodiments of the present invention involve directional indications (such as up and down), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0036] In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0037] In addition, "plurality" means two or more.
