[0020] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments and the accompanying drawings. Here, the schematic embodiments of the present invention and their description are used to explain the present invention, but are not intended to limit the present invention.

[0021] Embodiment 1 of the present utility model

[0022] Reference Figure 1 、 Figure 2 and Figure 3 A belt threading and extraction device for an underground coal mine includes a mounting plate 1 and a belt pressing assembly 2. The belt pressing assembly 2 is arranged at one end of the mounting plate 1. The belt pressing assembly 2 includes a connecting frame 21 and a pressing rod 22. The connecting frame 21 includes a bottom plate 211, a connecting plate 212 and a top plate 213. The bottom plate 211 and the top plate 213 are arranged in parallel. The bottom plate 211 is fixed to the mounting plate 1, and the connecting plate 212 is fixed between the bottom plate 211 and the top plate 213. The connecting plate 212 is located on the side of the bottom plate 211 away from the mounting plate 1.

[0023] Two clamping rods 22 are provided. Nuts 214 are fixed to the top plate 213, and the clamping rods 22 are threadedly connected to the nuts 214. The clamping rods 22 pass through the top plate 213. A clamping plate 221 is fixed to the bottom of the clamping rods 22, and a rotary handle 222 is fixed to the top of the clamping rods 22. A non-slip metal strip 215 is fixed to the top of the bottom plate 211. The non-slip metal strip 215 increases the friction between the belt and the clamping plate 221, making the belt more stable.

[0024] A first support plate 3 is provided at the end of the mounting plate 1 away from the base plate 211. Two second support plates 31 are fixed above the first support plate 3. The two second support plates 31 are arranged in parallel. A rocker 32 is provided between the two second support plates 31. A rotating shaft 33 is fixed at the center of the rocker 32 and is rotatably connected to the second support plates 31. One end of the rotating shaft 33 extends out of one of the second support plates 31 and is fixed to a rotating plate 34. A rocker 35 is provided at the end of the rotating plate 34 away from the rotating shaft 33. A steel wire rope 36 is wound around the rocker 32, and one end of the steel wire rope 36 is provided with a threading bar fixing assembly 4.

[0025] To remove the threading strip from the belt, place the belt on the mounting plate 1, place one side of the belt over the anti-slip metal strip 215, and turn the handle 222 to compress the belt via the pressing plate 221. Connect the end of the threading strip away from the pressing plate 221 to the threading strip fixing assembly 4, then rotate the rocker 35, and the wire rope 36 drives the threading strip out of the belt.

[0026] The threading strip fixing assembly 4 includes a first fixing block 41 and a second fixing block 42. The first fixing block 41 is in the shape of a cone, and the second fixing block 42 is in the shape of a rectangular block. An external thread is provided on the outer circumferential wall of the first fixing block 41, and a connecting hole 421 is provided on the second fixing block 42. An internal thread is provided in the connecting hole 421. The first fixing block 41 is inserted into the connecting hole 421 and is threadedly connected to the connecting hole 421. A mounting hole 411 is provided on the first fixing block 41, and one end of the threading strip is inserted into the mounting hole 411. Four connecting grooves 412 are provided on the outer circumferential wall of the end of the first fixing block 41 away from the wire rope 36. The four connecting grooves 412 are evenly arranged along the circumferential direction of the first fixing block 41, and the connecting grooves 412 are connected to the mounting hole 411.

[0027] Insert one end of the threading strip into the mounting hole 411, rotate the second fixing block 42 to move the second fixing block 42 toward one end of the wire rope 36, and the second fixing block 42 will squeeze the first fixing block 41 away from one end of the wire rope 36, so that the gap in the connecting groove 412 is reduced, thereby causing the outer wall of the first fixing block 41 to squeeze the threading strip, thereby fixing the threading strip.

[0028] The rotating plate 34 has an insertion hole 5 through which the rocker 35 passes and is secured by a stopper plate 51. This prevents the rocker 35 from falling out of the hole 5. A rod 52 is secured to the end of the stopper plate 51 away from the rocker 35. The second support plate 31 has a socket 53 for the rod 52. When the rocker 35 is not in motion, the rod 52 is inserted into the socket 53 to enhance its stability.

[0029] The implementation principle of the utility model of a coal mine underground belt threading strip extraction device is as follows: when removing the threading strip on the belt, first put the belt on the mounting plate 1, fix one side of the belt through the pressing plate 221, then insert one end of the threading strip into the mounting hole 411, rotate the second fixing block 42 to fix the threading strip, and then rotate the rocker 35 to rotate the rocker wheel 32, so that the wire rope 36 drives the threading strip to be separated from the belt, which is convenient for removing the threading strip on the belt.

[0030] Embodiment 2 of the present utility model

[0031] Reference Figure 4 and Figure 5 The difference from Example 1 is that the threading bar fixing assembly 4 includes a housing 43 and a clip 44. The housing 43 has a locking hole 431, and one end of the housing 43 is fixed to the wire rope 36. The three clips 44 form a frustum and are inserted into the locking hole 431. The inner wall of the clip 44 has an anti-slip groove 441. The outer circumferential wall of the clip 44 near the wire rope 36 has a mounting groove 442. A steel wire is tied to the mounting groove 442, and the steel wire binds the three clips 44 together.

[0032] When fixing the threading strip, insert one end of the threading strip from the end of the shell 43 away from the steel wire rope 36 into the locking hole 431, so that the threading strip extends out of the locking hole 431, then wrap the three clips 44 around the threading strip, and tie the steel wire to the mounting groove 442, and then insert the three clips 44 into the locking hole 431. As the clips 44 are inserted, the three clips 44 gradually clamp the threading strip, thereby fixing the threading strip.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention are included in the scope of protection of the present invention.
