Technical Field

[0001] The utility model relates to the technical field of underground coal mining, in particular to a light towing cable device for excavating tunnels in underground coal mines. Background Art

[0002] In coal mine tunnels, light cable dragging devices are mainly used for dragging and arranging cables to support the normal operation of tunneling machines and other mining equipment. Compared with heavy equipment, light cable dragging equipment usually has the characteristics of small size, light weight, easy operation and maintenance.

[0003] Light-duty cable-hauling equipment in roadways includes a monorail cable trolley, which is designed to reduce the labor intensity of workers. The monorail cable trolley can be used to easily drag cables in the roadway, improving work efficiency while ensuring the safety and stability of the cables. In addition, there are other equipment and technologies used to drag and place cables in the roadway, such as cable-hauling pulleys and cable conveyors. These equipment together constitute the scope of light-duty cable-hauling equipment in roadways.

[0004] In the prior art, since some impurities or moisture usually adhere to the surface of the cable inside the tunnel, long-term presence will cause the outer protective layer of the cable to be corroded. When the cable is towed by the cable support device, the cable will pass through the cable support device, causing impurities to adhere to the surface of the cable support device, so that the surface of the cable support device will also be corroded. Summary of the Invention

[0005] The purpose of the utility model is to provide a light cable towing device for underground coal mine excavation tunnels, which can remove impurities on the surface of the cable through a scraper, and the reset spring pushes the scraper to push the impurities out of the first conduit, thereby avoiding corrosion of the cable and the internal structure of the bracket by the impurities, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a light-weight towing cable device for an underground coal mine excavation roadway, comprising a guide rail and a bracket slidably connected to the outside of the guide rail, a plurality of guide pulleys being rotatably connected to the interior of the bracket, a debris removal component being provided inside the bracket, the debris removal component comprising a first guide tube hingedly connected to the left side of the interior of the bracket;

The same scraper is fixedly connected to the opposite surfaces of the two corresponding sliders. The scraper is slidably connected in the first conduit. A return spring is fixedly connected to the side of the slide groove away from the scraper, and the other end of the return spring is fixedly connected to the side of the scraper close to the return spring.

[0008] Preferably, both sides of the bracket are fixedly connected to supports, and the upper sides of the two supports are fixedly connected to rubber pads, and the first conduit is overlapped on the upper side of the rubber pad on the left after rotation.

[0009] Preferably, a dehumidification component is provided in both the interior of the bracket and the interior of the first conduit, and the dehumidification component includes a guide groove provided in the interior of the first conduit.

[0010] Preferably, the wire groove is connected to one of the multiple slide grooves, the front of one of the multiple sliders is fixedly connected to a striker rod, the striker rod is slidably connected in the guide groove, and a pressure sensor is fixedly installed inside the first conduit, and after the striker rod moves, it is squeezed and contacted with the side of the pressure sensor close to the striker rod.

[0011] Preferably, the striker is L-shaped, and the shape of the striker is adapted to the shape of the guide groove.

[0012] Preferably, a fan is fixedly mounted on the front of the bracket, the fan is electrically connected to the pressure sensor, and a straight air duct is opened inside the bracket, and the straight air duct is located on the back of the fan.

[0013] Preferably, a second duct is hingedly connected to the right side of the interior of the bracket, and an air inlet is opened on one side of the front of the second duct, and the air inlet is connected to the straight air duct.

[0014] Preferably, a spiral air duct is provided inside the second conduit, and there are multiple spiral air ducts, and the multiple spiral air ducts are connected to the same air inlet.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The scraper cleans impurities on the cable surface by squeezing the scraper, and the return spring pushes the scraper to push the impurities out of the first conduit. Since the cable is always in contact with the scraper during the sliding process inside the first conduit, the scraper removes impurities on the cable surface, and the return spring pushes the scraper to push the impurities out of the first conduit, preventing impurities from corroding the cable and the internal structure of the bracket;

[0017] 2. While removing impurities from the cable surface through the scraper, external airflow is extracted to dry the moisture on the outside of the second conduit and the cable. Since the airflow extracted from the outside by the fan flows in a spiral pattern inside the second conduit, and the spiral flow has the advantages of high turbulence and large heat transfer area, it accelerates the evaporation of moisture inside the second conduit, further preventing the cable and the internal structure of the bracket from being corroded.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] The utility model provides a technical solution:

[0029] See also Figures 1 to 6A light towing cable device for underground coal mine excavation tunnels includes a guide rail 1 and a bracket 2 slidably connected to the outside of the guide rail 1. The bracket 2 has a plurality of guide pulleys 3 rotatably connected thereto. The bracket 2 is provided with a debris removal component 4, which includes a first guide tube 41 hinged to the left side of the bracket 2.

[0030] A slide groove 42 is provided inside the first conduit 41, and there are multiple slide grooves 42. Slide blocks 43 are slidably connected to the inside of each of the multiple slide grooves 42. The same scraper 44 is fixedly connected to the opposite surfaces of the two corresponding sliders 43. The scraper 44 is slidably connected inside the first conduit 41. A return spring 45 is fixedly connected to the side of the slide groove 42 away from the scraper 44, and the other end of the return spring 45 is fixedly connected to the side of the scraper 44 close to the return spring 45.

[0031] Both sides of the bracket 2 are fixedly connected to the supports 46 , and the upper sides of the two supports 46 are fixedly connected to the rubber pads 47 . After the first conduit 41 is rotated, it overlaps the upper side of the rubber pad 47 on the left side.

[0032] By adopting the above technical solution, first, the cable is passed through the first conduit 41. When the cable enters the first conduit 41, it will pass through the scraper 44 inside it. Then the scraper 44 is pushed, so that the two sliders 43 on the outside of the scraper 44 will slide inside the slide groove 42 inside the first conduit 41 and push the return spring 45 inside the slide groove 42. When the slider 43 can no longer move, the scraper 44 will scrape off the impurities remaining on the outside of the cable, and the cable passing through the first conduit 41 will reach the top of the wire wheel 3 inside the bracket 2. Then the bracket 2 changes its position through the guide rail 1, and the cable will be pulled. When the cable is not in a straight state, the first conduit 4 1 will tilt downward and rest on the support 46 on the left side of the bracket 2, and the rubber pad 47 above the support will support the first conduit 41. When the scraper 44 loses the push of the cable, the return spring 45 will push the scraper 44, so that part of the scraper 44 is exposed outside the first conduit 41, and the scraped impurities are pushed out of the first conduit 41. Since the cable is always in contact with the scraper 44 during the sliding process inside the first conduit 41, the scraper 44 will remove impurities on the surface of the cable, and the return spring 45 pushes the scraper 44 to push the impurities out of the first conduit 41, thereby preventing the impurities from corroding the cable and the internal structure of the bracket 2.

[0033] Specifically, such as Figures 4 to 6 As shown, a dehumidification component 5 is provided in both the interior of the bracket 2 and the interior of the first conduit 41 . The dehumidification component 5 includes a guide groove 51 provided in the interior of the first conduit 41 .

[0034] The wire groove is connected to one of the multiple slide grooves 42, and the front of one of the multiple sliders 43 is fixedly connected to a striker 52. The striker 52 is slidably connected in the guide groove 51. A pressure sensor 53 is fixedly installed inside the first conduit 41. After the striker 52 moves, it is squeezed and contacted with the side of the pressure sensor 53 close to the striker 52.

[0035] The striker 52 is L-shaped, and the shape of the striker 52 matches the shape of the guide groove 51 .

[0036] A fan 54 is fixedly mounted on the front of the bracket 2 , and the fan 54 is electrically connected to the pressure sensor 53 . A straight air duct 55 is provided inside the bracket 2 , and the straight air duct 55 is located on the back of the fan 54 .

[0037] A second duct 56 is hingedly connected to the right side of the interior of the bracket 2 , and an air inlet 57 is opened on one side of the front of the second duct 56 . The air inlet 57 is connected to the straight air duct 55 .

[0038] A spiral air duct 58 is defined inside the second duct 56 , and there are multiple spiral air ducts 58 , which are connected to the same air inlet 57 .

[0039] By adopting the above technical solution, first, the cable will enter the second conduit 56 after passing over the wire wheel 3, and the scraper 44 will drive the striker 52 to slide inside the guide groove 51 after being pushed. After the striker 52 contacts the pressure sensor 53 inside the first conduit 41, the fan 54 will be started by the external controller, and the fan 54 will draw the external air flow into the straight air duct 55. Then the air flow passes through the air inlet 57 on the side of the second conduit 56. Since the air inlet 57 is connected with the multiple spiral air ducts 58 inside the second conduit 56, the air flow flows in the second conduit 56 in a spiral manner. Since the air flow drawn from the outside by the fan 54 flows in the second conduit 56 in a spiral manner, and the spiral flow has the advantages of high turbulence and large heat transfer area, it accelerates the evaporation of moisture inside the second conduit 56, further avoiding corrosion of the cable and the internal structure of the bracket 2.

[0040] Working principle: First, after the cable enters the first conduit 41, it will pass through the scraper 44 inside it, and then the scraper 44 will be pushed, so that the two sliders 43 on the outside of the scraper 44 will slide inside the slide 42 inside the first conduit 41 and push the return spring 45 inside the slide 42. When the slider 43 can no longer move, the scraper 44 will scrape off the impurities remaining on the outside of the cable, and the cable passing through the first conduit 41 will reach the top of the wire wheel 3 inside the bracket 2. After the bracket 2 changes its position through the guide rail 1, the cable will be pulled. When the cable is not in a straight state, the first conduit 41 will tilt downward and rest on the support 46 and rubber pad 47 on the left side of the bracket 2, and the return spring 45 will push the scraper 44 so that part of the scraper 44 is exposed outside the first conduit 41, and the scraped impurities are pushed out of the first conduit 41. The cable will enter the second conduit 56 after passing over the wire wheel 3, and the scraper 44 will drive the striker 52 to slide inside the guide groove 51 after being pushed. After the striker 52 contacts the pressure sensor 53 inside the first conduit 41, the fan 54 will be started through the external controller, and the fan 54 will draw the external air flow into the straight air duct 55. Then the air flow passes through the air inlet 57 on the side of the second conduit 56. Because the air inlet 57 is connected with multiple spiral air ducts 58 inside the second conduit 56, the air flow flows in the second conduit 56 in a spiral manner.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents.
