Description

Technical Field

[0001] This utility model relates to the field of mining technology, and in particular to a lightweight towing cable device for underground coal mine tunneling roadways. Background Technology

[0002] To facilitate the movement and protection of underground cables and prevent them from scraping against the ground during movement, a lightweight cable-dragging device for underground coal mine tunneling is used. This device lifts the cables, making them easier to move. Existing lightweight cable-dragging devices for underground coal mine tunneling typically use rollers and rails to move suspended cables. However, due to the complex working environment underground, dust and particles can easily get into the rails. These dust particles can obstruct the rollers' movement, causing them to jam and hindering cable movement. Utility Model Content

[0003] The purpose of this invention is to solve the problem in the existing technology where dust particles obstruct the rolling of the rollers on the slide rail, easily causing the rollers to get stuck and affecting the movement of the cable. Therefore, a lightweight cable dragging device for underground coal mine tunneling roadways is proposed.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design a lightweight cable-dragging device for underground coal mine tunneling roadways, including a guide rail, with multiple rollers on both sides of the guide rail, each roller connected to a side plate, and a U-shaped section connected between two parallel side plates via a connecting mechanism. A connecting plate is fixedly connected to the side plate, and a cleaning block is fixedly connected to both ends of the two connecting plates. The lower end of the cleaning block contacts the guide rail. Multiple first slag discharge ports are equally spaced on the guide rail, and multiple second slag discharge ports are equally spaced on the guide rail. The first and second slag discharge ports are staggered, and the total length of the second and first slag discharge ports is equal to the width of the cleaning block.

[0006] Preferably, both the cleaning block and the guide rail are made of wear-resistant materials.

[0007] Preferably, the connecting mechanism includes a connecting cylinder, which is fixedly connected to the side plate, and the end of the U-shaped part is located inside the connecting cylinder. The connecting cylinder and the U-shaped part are fixed together by a fixing mechanism.

[0008] Preferably, an abutment mechanism is provided between the side plate and the guide rail.

[0009] Preferably, the fixing mechanism includes a plurality of second fixing holes equally spaced on the U-shaped part, and a bolt is threaded through the lower end of the connecting cylinder, the bolt being threadedly connected to one of the second fixing holes.

[0010] Preferably, an elastic sleeve is provided at the middle position of the U-shaped portion.

[0011] Preferably, the abutting mechanism includes a mounting groove, and the side plate is provided with a mounting groove on the side near the guide rail. An abutting wheel is provided in the mounting groove, and the abutting wheel abuts against the guide rail.

[0012] Preferably, the guide rail has multiple first fixing holes at equal intervals.

[0013] The present invention proposes a lightweight cable-dragging device for underground coal mine tunneling, which has the following advantages: when the roller rolls, it drives the cleaning block to move. The cleaning block pushes the dust particles on the guide rail, causing the dust particles to be discharged from the first and second slag discharge ports. This prevents the particles from obstructing the rolling of the roller and ensures the normal movement of the cable. Furthermore, because the first and second slag discharge ports are staggered, when the roller passes through the first and second slag discharge ports, part of the roller is fully supported by the rail, preventing the roller from getting stuck when passing through the slag discharge ports and ensuring the normal operation of the roller.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example 1: Refer to Figure 1-2 A lightweight cable-dragging device for underground coal mine tunneling includes a guide rail 1 with multiple first fixing holes 2 evenly spaced on the guide rail 1. Bolts are placed in the first fixing holes 2 to fix the guide rail 1, thereby facilitating its fixation.

[0021] Multiple rollers 3 are provided on both sides of the guide rail 1, and side plates 12 are connected to each roller 3. The connecting bearing between the roller 3 and the side plate 12 is a sealed bearing to prevent dust from entering and to avoid affecting the rotation of the roller 3. A U-shaped part 10 is connected between two parallel side plates 12 through a connecting mechanism. A connecting plate 5 is fixedly connected to the side plate 12, and a cleaning block 4 is fixedly connected to both ends of the two connecting plates 5. The lower end of the cleaning block 4 is in contact with the guide rail 1. Multiple first slag discharge ports 6 are opened at equal intervals on the guide rail 1, and multiple second slag discharge ports 7 are opened at equal intervals on the guide rail 1. The second slag discharge ports 7 and The total length of the first slag discharge port 6 is equal to the width of the cleaning block 4. When the roller 3 rolls, it drives the cleaning block 4 to move. The cleaning block 4 pushes the dust particles on the guide rail 1, so that the dust particles are discharged from the first slag discharge port 6 and the second slag discharge port 7, preventing the particles from obstructing the rolling of the roller 3. Furthermore, since the first slag discharge port 6 and the second slag discharge port 7 are staggered, when the roller 3 passes through the first slag discharge port 6 and the second slag discharge port 7, part of the roller 3 is fully supported by the track, preventing the roller 3 from getting stuck when passing through the slag discharge port, and ensuring the normal operation of the roller 3.

[0022] Both the cleaning block 4 and the guide rail 1 are made of wear-resistant materials, such as wear-resistant steel, which improves the wear resistance of the cleaning block 4 and the guide rail 1 and helps to extend the service life of the device.

[0023] By passing the cable through the U-shaped part 10, the U-shaped part 10 will move when the cable is pulled. The U-shaped part 10 will move the side plate 12. The side plate 12 will move and the roller 3 will roll. When the cleaning block 4 moves, it will push the particles on the guide rail 1. When the particles pass through the first slag discharge port 6, the particles on one side of the cleaning block 4 will be discharged from the first slag discharge port 6. When the particles pass through the second slag discharge port 7, the particles on the other side of the cleaning block 4 will be discharged from the second slag discharge port 7.

[0024] Example 2: Refer to Figure 1-4As another preferred embodiment of this utility model, based on embodiment 1, the connecting mechanism includes a connecting cylinder 9, which is fixedly connected to the side plate 12. The end of the U-shaped part 10 is located inside the connecting cylinder 9. The connecting cylinder 9 and the U-shaped part 10 are fixed together by a fixing mechanism. The fixing mechanism includes a plurality of second fixing holes 14 that are equally spaced on the U-shaped part 10. A bolt 13 is threaded through the lower end of the connecting cylinder 9. The bolt 13 is threadedly connected to one of the second fixing holes 14. By adjusting the position of the U-shaped part 10 in the connecting cylinder 9, and then fixing it by the bolt 13 and the second fixing hole 14, the height of the cable placed on the U-shaped part 10 can be adjusted to meet different needs in the tunnel. Due to the complexity of the underground environment, ordinary bolts are prone to corrosion. The bolt 13 is made of stainless steel to prevent corrosion and to facilitate disassembly of the bolt 13.

[0025] An elastic sleeve 8 is provided in the middle of the U-shaped part 10. The elastic sleeve 8 is made of rubber material and plays a protective role in buffering the contacting cable to prevent cable wear.

[0026] Example 3: Reference Figure 4 As another preferred embodiment of this utility model, based on embodiment 2, an abutment mechanism is provided between the side plate 12 and the guide rail 1. The abutment mechanism includes a mounting groove 15. The mounting groove 15 is provided on the side of the side plate 12 near the guide rail 1. An abutment wheel 11 is provided in the mounting groove 15. The abutment wheel 11 abuts against the guide rail 1, which prevents the side plate 12 from swaying left and right, thereby ensuring the stability of the roller 3 when rolling.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
