Description

Technical Field

[0001] This utility model relates to a self-moving and storage device for tunneling cables, belonging to the technical field of auxiliary equipment for coal mining. Background Technology

[0002] During the excavation of underground tunnels, the roadheader continuously advances and crawls forward, requiring increasingly longer cables. As a result, a certain number of meters of cable need to be stored. The traditional method is to coil the cable and place it on the tunnel wall. This method has a small cable storage capacity, and when the stored cable is used up, a new cable needs to be connected, which brings some inconvenience to the excavation work.

[0003] In addition, during the forward crawling process of the tunnel boring machine, the required cables need to be dragged forward manually. After the tunnel boring machine completes a cycle of cutting, it needs to retreat for support work. At this time, it is necessary to manually pull the cables back and fix them to the tunnel wall. This operation is troublesome, wastes labor, and has low work efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a self-moving and storage device for tunneling cables, so as to solve the technical problems existing in the prior art.

[0005] The technical solution adopted by this utility model is as follows: a self-moving and storage device for tunneling cables, including a first cable-drafting frame, a second cable-drafting frame, a third cable-drafting frame, and a cable storage box. The first cable-drafting frame is installed on the end of the mobile tail section near the roadheader. The second cable-drafting frame is installed on a receiving trolley. A fixing post is fixed on the right side of the second cable-drafting frame on the mobile tail section. The third cable-drafting frame is installed on the part of the mobile tail section away from the roadheader. The cable storage box is installed on the end of the mobile tail section away from the roadheader. The cable is stored inside the cable storage box. The upper end of the fixing post and the part of the mobile tail section located on the right side of the second cable-drafting frame are fixed. Below the fixed column, there are respectively a steering pulley. A steel wire rope is fixed on the third towing cable frame. The other end of the steel wire rope passes through the upper and lower steering pulleys in sequence and is fixed to the first towing cable frame. A cable sliding bracket is slidably connected to the steel wire rope. The part of the cable located between the second towing cable frame and the third towing cable frame is suspended on the steel wire rope through the cable sliding bracket. One of the cable sliding brackets adjacent to the second towing cable frame is fixed to the second towing cable frame. After the cable comes out of the cable storage box, it passes through the third towing cable frame and the second towing cable frame in sequence and is electrically connected to the tunnel boring machine.

[0006] Preferably, a bridge is provided between the cable storage box and the third cable rack.

[0007] The beneficial effects of this utility model are:

[0008] 1. Compared with the prior art, in this utility model, the receiving trolley moves back and forth with the bridge frame of the roadheader, enabling the cable to be retracted and deployed. When the roadheader pulls the moving tail forward, this utility model moves forward along with it, thus realizing the self-movement of the entire device. There is no need for manual dragging of cables or supervision. The cable storage box can store about 200 meters of cable, which greatly reduces the number of times new cables need to be connected, improves productivity, ensures safe production, saves labor, and is convenient, safe and reliable to operate.

[0009] 2. After the tunneling machine cable self-moving and storage device is put into use, it is calculated that each tunneling machine can save 1 person's manpower. The total annual savings for all 6 tunneling machines in the mine is 6 × 250 × 365 = 547,500 yuan. Attached Figure Description

[0011] The reference numerals in the accompanying drawings include: 1. Moving tail section; 2. First cable tray; 3. Receiving trolley; 4. Second cable tray; 5. Steering pulley; 6. Wire rope; 7. Cable sliding hanger; 8. Third cable tray; 9. Bridge; 10. Cable storage box; 11. Fixed column. Detailed Implementation

[0012] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0013] Example 1:

[0014] A self-moving and storage device for tunneling cables, such as Figure 1As shown, the mobile tail section includes, from right to left, a first cable support frame 2, a second cable support frame 4, a third cable support frame 8, and a cable storage box 10. The right end of the mobile tail section 1 is close to the roadheader. The mobile tail section 1 is existing. The first cable support frame 2 is installed on the right end of the mobile tail section 1. The second cable support frame 4 is installed on the receiving trolley 3. The receiving trolley 3 is existing. The third cable support frame 8 is installed on the left side of the mobile tail section 1. The cable storage box 10 is installed on the left end of the mobile tail section 1. The cable is stored inside the cable storage box 10. A bridge 9 is provided between the cable storage box 10 and the third cable support frame 8. A fixed column 11 is fixed on the right side of the mobile tail section 1. The second cable support frame 4 is located to the left of the fixed column 11. Steering pulleys 5 are respectively installed at the upper right end of the fixed column 11 and below the fixed column 11 on the mobile tail section 1. A steel wire rope 6 is fixed on the cable towing frame 8. The other end of the steel wire rope 6 passes through two guide pulleys 5 and is then fixed to the first cable towing frame 2. A cable sliding bracket 7 is slidably connected to the steel wire rope 6. The part of the cable located between the second cable towing frame 4 and the third cable towing frame 8 is suspended on the steel wire rope 6 through the cable sliding bracket 7. The upper end of the second cable towing frame 4 is slidably connected to the steel wire rope 6. The rightmost cable sliding bracket 7 is fixed to the second cable towing frame 4. Thus, when the second cable towing frame 4 moves to the left, it can drive all the cable sliding brackets 7 to slide to the left along the steel wire rope 6 to realize the cable storage. When the second cable towing frame 4 moves to the right, it first drives the rightmost cable sliding bracket 7 to move to the right. When the second cable towing frame 4 continues to move to the right, it can pull the remaining cable sliding brackets 7 to slide to the right along the steel wire rope 6 in turn.

[0015] After the cable comes out of the cable storage box 10, it passes through the bridge 9, the third cable support 8, and the second cable support 4 in sequence before being electrically connected to the tunnel boring machine.

[0016] The receiving trolley 3 moves back and forth following the bridge frame of the roadheader, enabling the cable to be retracted and extended, thus eliminating the need for manual cable dragging. When the roadheader pulls the moving tail 1 forward, this utility model moves forward along with it, thus realizing the self-movement of the entire device.

[0017] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
