Description

Technical Field

[0001] This utility model relates to the field of mining technology, and specifically discloses a special cable splitter for fully mechanized coal mining faces. Background Technology

[0002] According to relevant regulations, underground fully mechanized mining faces in coal mines need to be equipped with gas sensors, signaling devices, lighting, and other equipment. Due to the harsh environment, long working hours, high labor intensity, and confined space of the hydraulic supports, the cables supplying power to these devices are often simply tied together with wire and suspended from the lifting rings of the hydraulic supports, maintaining a certain curvature to allow for cable expansion and contraction during later support relocation. When a cable fails, it is difficult to quickly identify and replace it. Therefore, the workers generally leave the old cable untouched and lay a new one. Over time, this makes the already cramped space even more cluttered. Because the cable lifting rings of the hydraulic supports are large, the cables can be pulled freely. As a result, some cables between hydraulic supports sag significantly, and some have insufficient cable slack. Moving the hydraulic supports (referred to as support relocation) poses a significant safety hazard. Severely sagting cables also frequently entangle workers' necks, increasing the safety risks. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a special cable splitter for fully mechanized coal mining faces, aiming to reduce the aforementioned safety hazards.

[0004] To achieve the objectives of this utility model, the following technical solution is employed: A special cable distributor for fully mechanized coal mining faces includes a housing, track grooves, a cable routing ring, welding holes, a spring, a slider, a rotating shaft, and a winding roller. The feature is that two identical track grooves are arranged parallel to each other on the same plane of the housing. The slider is placed within the track grooves and can slide within them. A rotating shaft is vertically positioned on the side of the slider closest to the housing surface, and a winding roller is rotatably mounted on the rotating shaft. One end of a spring is fixedly connected to one end of the inner side of the track groove, and the other end of the spring is connected to the slider. Under the action of the spring, the winding roller is pushed to the rightmost end of the track groove. In the other parallel track groove, the slider and one end of the inner side of the track groove exchange their connection positions with the spring, pushing the winding roller to the leftmost end of the track groove. A cable routing ring is provided at one end of the track groove on the housing surface away from the winding roller, and welding holes are provided penetrating the housing at the four corners.

[0005] Preferably, the cross-sectional shape of the track groove is "convex", with the smaller opening located on the surface of the housing, and the slider is engaged in the lower half of the track groove.

[0006] The beneficial effects of this utility model are: This utility model can fold the drooping cable elastically under the hydraulic support, which can not only prevent workers from accidentally touching the cable and causing safety hazards, but also set the cable extension and retraction amount between the racks more evenly, avoiding damage to the cable due to insufficient margin when moving the rack. In addition, it is convenient to find faults, easy to disassemble and assemble, simple to manufacture, and widely available materials, and has a broad market prospect. Attached Figure Description

[0009] To deepen the understanding of this utility model, the utility model will be further described in detail below with reference to the embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the protection scope of this utility model.

[0010] Please see Figures 1-4 , Figures 1-4This is a structural diagram of a special cable distributor for fully mechanized coal mining faces, including a housing 101, a track groove 102, a cable routing ring 103, a welding hole 104, a spring 201, a slider 202, a rotating shaft 203, and a winding roller 204. Its features are: two identical track grooves 102 are arranged parallel to each other on the same plane of the housing 101; the slider 202 is placed in the track groove and can slide within it; the rotating shaft 203 is vertically arranged on the side of the slider 202 closest to the surface of the housing 101; the winding roller 204 is rotatably mounted on the rotating shaft 203; one end of the spring 201 is fixedly connected to one end of the inner side of the track groove 102, and the other end of the spring 201 is connected to the slider 202; under the action of the spring 201, the winding roller 204 is pushed to the rightmost end of the track groove 102. In another parallel track groove 102, the slider 202 and one end of the inner side of the track groove 102 exchange their connection positions with the spring 201, so that the winding roller 204 is pushed to the leftmost end of the track groove 102. A wire guide ring 103 is provided at one end of the track groove 102 on the surface of the housing 101 away from the winding roller 204, and welding holes 104 are provided through the housing 101 at the four corners of the housing 101.

[0011] Preferably, the cross-sectional shape of the track groove is "convex", with the smaller opening located on the surface of the housing 101, and the slider 202 is engaged in the lower half of the track groove.

[0012] Please see Figures 5-7 , Figures 5-7 This refers to the working state of this utility model during the relocation process.

[0013] Please see Figure 8 , Figure 8 This is a diagram showing the installation location of this utility model.

[0014] In use, the back of this utility model is welded to the bottom beam 401 of the hydraulic support, so that the track groove 102 is perpendicular to the forward direction of the hydraulic support. The cable 301 is passed through the cable routing ring 103 from the direction close to this utility model and continues forward, passing around the two winding rollers 204, and exiting from another cable routing ring 103 to connect to the next utility model.

[0015] When one of the hydraulic supports moves, due to the tension of the cable 301, the two winding rollers 204 move closer to each other in the track groove 102, releasing the excess cable 301. When the other hydraulic supports move forward, the two winding rollers 204 move away under the action of the spring 201, storing the excess cable 301 in the device. The hydraulic supports move forward alternately, while the winding rollers 204 continue to move in the track groove 102, realizing the safe operation of the device and the safe production of the fully mechanized mining face.

[0016] To facilitate cable installation, the cable routing ring 103 can be designed as an openable structure similar to a key fob.

[0017] When a cable 301 is damaged, it can be easily removed and replaced from this utility model, avoiding the cable replacement method mentioned in the background art, further reducing safety hazards and optimizing the working environment.
