Detailed Implementation

[0021] 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.

[0022] Please see Figure 1 and Figure 4 This utility model provides an embodiment of a tracked cable trough for a tunneling face, comprising a cable trough plate 1, a cable mounting track 3 installed on the inner side of the cable trough plate 1, and a partition plate 2 installed below the cable mounting track 3. The cable trough plate 1 and the partition plate 2 are fixedly connected. The surface of the partition plate 2 is provided with multiple material leakage holes 5. The partition plate 2 can perform material leakage operation through the multiple material leakage holes 5 to prevent the material from accumulating on the partition plate 2 and causing the cable mounting track 3 to jam.

[0023] Please see Figures 2 to 4 The cable installation track 3 includes two elastic bands 303, and multiple connecting frames 304 are installed between the two elastic bands 303. Both ends of the multiple connecting frames 304 are fixedly connected to the two elastic bands 303. A locking knob 308 is installed on the upper end of the connecting frame 304. Two elastic strips 306 are installed on the inner side of the connecting frame 304. Multiple arc-shaped guide grooves 307 are provided on the side of the adjacent two elastic strips 306. Multiple cables are arranged between the adjacent two elastic strips 306. The cables are installed on the inner side of the adjacent two arc-shaped guide grooves 307. Multiple splicing covers 301 are installed on the outer side of the multiple connecting frames 304, so that the connecting frame 304 can elastically position the cables through the adjacent two elastic strips 306, avoiding frictional contact between the cables and the cable tray plate 1 and the partition plate 2 when the elastic strips 306 position and support the cables, effectively maintaining the safety of the cables in use.

[0024] The bottom end of the locking knob 308 passes through the splicing cover 301 and is connected to the connecting frame 304 by a thread. The connecting frame 304 and the splicing cover 301 are connected by the locking knob 308. Multiple connecting frames 304 are installed one-to-one with the locking knob 308. Positioning pieces 305 are fixedly installed at both ends of the splicing cover 301. A positioning pin 302 is installed between two adjacent splicing covers 301. Two adjacent splicing covers 301 are rotatably connected by a positioning pin 302. The locking knob 308 can keep the distance between the connecting frame 304 and the splicing cover 301 stable.

[0025] Please see Figure 1 and Figure 3 Multiple positioning units 4 are installed on both sides of the cable trough plate 1. Two adjacent positioning units 4 are symmetrically installed relative to the splicing cover 301. The positioning unit 4 includes a limiting sleeve 401. A positioning rod 403 is slidably connected to the inner side of the limiting sleeve 401. A support spring 402 is provided between the limiting sleeve 401 and the positioning rod 403. The limiting sleeve 401 is fixedly connected to the cable trough plate 1. A groove is provided on one side of the positioning piece 305. One end of the positioning rod 403 passes through the cable trough plate 1 and is inserted into the inner side of the groove. The limiting sleeve 401 and the positioning rod 403 are connected by the support spring 402. Under the support of the support spring 402, the positioning rod 403 can automatically insert into the inner side of the positioning piece 305, thereby facilitating the support of the cable installation track 3 and maintaining the stability of the distance between the cable installation track 3 and the partition plate 2.

[0026] In use, during the tunneling process in a coal mine, one end of the cable installation track 3 is connected to the roadheader at the tunneling face. The cable is placed in the arc-shaped guide groove 307 provided on the elastic strip 306, so that the connecting frame 304 can elastically position the cable through two adjacent elastic strips 306. Two adjacent splicing covers 301 are rotatably connected by positioning pins 302. When the roadheader moves, it can drive the track composed of multiple splicing covers 301 to bend and follow.

[0027] Simultaneously, the splicing cover 301 drives the positioning piece 305 to automatically separate from the positioning rod 403. Then, the splicing cover 301 drives the connecting frame 304 to move through the locking knob 308. Multiple connecting frames 304 are connected by two elastic bands 303. At this time, the two elastic bands 303 can elastically connect multiple connecting frames 304, thereby maintaining the stability of multiple splicing covers 301 when bending. The locking knob 308 can keep the distance between the connecting frame 304 and the splicing cover 301 stable, thereby avoiding frictional contact between the cable and the cable tray plate 1 and the partition plate 2 when the elastic strip 306 supports the cable positioning, effectively maintaining the safety of cable use.

[0028] When the cable installation track 3 is reset, the splicing cover 301 falls back to the inside of the cable trough plate 1 under its own weight. At this time, the positioning rod 403 can automatically insert into the inside of the positioning piece 305 under the support of the support spring 402, which facilitates the support of the cable installation track 3 and keeps the distance between the cable installation track 3 and the partition plate 2 stable. This allows the partition plate 2 to discharge the ore through multiple discharge holes 5, avoiding the accumulation of ore on the partition plate 2 and causing the cable installation track 3 to jam.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
