[0034] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, some features described in the examples may be combined in other examples.

[0035] like Figures 1 to 7 As shown, this embodiment provides an inclined shaft hoist, including a guide rail 100, a skip 200 is provided on the guide rail 100, two sets of guide wheels 201 are installed at the bottom of the skip 200, each set of guide wheels 201 is in rolling cooperation with the guide rail 100, and a deceleration mechanism 300 for decelerating the skip 200 is provided at the bottom of the skip 200.

[0036] The deceleration mechanism 300 includes a mounting plate 301 fixed to the bottom of the skip 200. Slider 302s are slidably connected to both sides of the mounting plate 301 near the adjacent guide wheel 201. Guide posts 303s are fixedly connected to the opposite sides of the two sliders 302. An L-shaped plate 305 is slidably connected to the end of the guide post 303 away from the slider 302. A compression spring 304 is sleeved on the outer surface of the guide post 303. The two ends of the compression spring 304 are fixedly connected to the slider 302 and the L-shaped plate 305, respectively. A brake disc 306 is fixedly connected to the L-shaped plate 305 to increase the friction with the guide rail 100. The deceleration mechanism 300 also includes a triggering component disposed at the bottom of the mounting plate 301 and a pushing component disposed within the mounting plate 301. The triggering component is triggered when it contacts the bulge. When triggered, the pushing component is driven to bring the brake disc 306 closer to the guide rail 100.

[0037] The triggering component includes a sliding plate 311 that is slidably inserted into the bottom of the mounting plate 301. A connecting shaft 312 is rotatably connected inside the sliding plate 311 and passes through the sliding plate 311. Rotating wheels 313 are fixedly connected to both ends of the connecting shaft 312. The rotating wheels 313 are symmetrical about the sliding plate 311 and roll with the guide rail 100.

[0038] The pushing component includes a guide plate 321, which is slidably connected to the mounting plate 301. Connecting rods 323 are rotatably connected to both sides of the guide plate 321 near the slider 302. The connecting rods 323 are rotatably connected to the adjacent slider 302 and are inclined. The guide plate 321 is fixedly connected to the sliding plate 311. When the triggering component is activated, it can push the guide plate 321 upwards. When the guide plate 321 slides upwards, it can push the reset spring 322 to slide away from the mounting plate 301 by cooperating with the connecting rods 323. At least two reset springs 322 are fixedly connected to the top of the guide plate 321. The end of the reset spring 322 away from the guide plate 321 is fixedly connected to the mounting plate 301. The reset springs 322 are used to reset the guide plate 321.

[0039] The slider 302 is L-shaped to limit the sliding distance of the slider 302. The L-shaped plate 305 is L-shaped and at least two reinforcing ribs 3051 are fixedly connected between the inner walls of the L-shaped plate 305 to improve the strength of the L-shaped plate 305.

[0040] One side of the skip 200 is fixedly connected to an external steel wire rope, and the other end of the steel wire rope is fixedly connected to an external receiving drum. The shaft end of the authorized drum is fixedly connected to the output end of an external motor. When the skip 200 is in use, the external motor drives the external receiving drum to wind up the external steel wire rope, thereby pulling the skip 200. Through the rolling cooperation between the guide wheel 201 and the guide rail 100, the skip 200 is driven on the inclined guide rail 100 to transport coal from bottom to top.

[0041] by Figure 1 For reference, both the deceleration mechanism 300 and the auxiliary mechanism 400 are located on the lifting direction side of the adjacent guide wheel 201. When a bulge occurs, the deceleration mechanism 300 and the auxiliary mechanism 400 will first come into contact with the bulge, thereby reducing the speed appropriately before the guide wheel 201 comes into contact with the bulge.

[0042] Further examples:

[0043] The rotating wheel 313 is provided with an auxiliary mechanism 400 for assisting in cleaning the guide rail 100. The auxiliary mechanism 400 includes multiple grooves 401 formed on the outer surface of the rotating wheel 313. The grooves 401 are used to clean and collect mud-like impurities on the guide rail 100. Each groove 401 is slidably connected to a scraper 402 and a guide rod 403. A connecting ring 404 is fixedly connected to the side of the guide rod 403 away from the scraper 402. When the connecting ring 404 is pulled, the scraper 402 can be simultaneously driven to slide in the groove 401 through the guide rod 403. A locking pin 405 is inserted into the connecting ring 404. The locking pin 405 passes through one end of the connecting ring 404 and engages with the rotating wheel 313. The scraper 402 is located on the side of the groove 401 near the connecting shaft 312. The guide rod 403 is located at the bottom of the groove 401. The width of the scraper 402 is the same as that of the groove 401.

[0044] The working principle of all the content in the above embodiments is as follows:

[0045] Initial state: The return spring 322 is in normal state, the guide plate 321 is at the bottom of the inner wall of the mounting plate 301, the compression spring 304 is in normal state, and the brake disc 306 corresponds to both sides of the inner wall of the guide rail 100, but is in a non-contact state.

[0046] The following describes the working principle and beneficial effects of the speed reduction mechanism 300:

[0047] When the skip 200 transports coal from bottom to top on the inclined guide rail 100 through the rolling cooperation between the guide wheel 201 and the guide rail 100, if there is no obvious bulge on the guide rail 100, the rotating wheel 313 rolls on the guide rail 100. When the rotating wheel 313 comes into contact with the inconspicuous bulge, it will drive the sliding plate 311 to slide slightly into the mounting plate 301 through the connecting shaft 312. This will drive the brake disc 306 to move a small distance towards the inner wall of the guide rail 100 through the pushing component, but without making contact.

[0048] When a bulge exceeding the set height appears on the guide rail 100, the rotating wheel 313 contacts the higher bulge, causing the bulge to push the rotating wheel 313 upward, which in turn drives the connecting shaft 312 and the sliding plate 311 upward. The sliding plate 311 slides into the mounting plate 301, which in turn pushes the connecting shaft 312 towards the return spring 322. The return spring 322 is compressed, and at the same time, the guide plate 321 pushes the connecting rod 323 to move upward on the side closest to the guide plate 321, which in turn causes the connecting rod 323 to rotate and push the slider 302 away from the mounting plate 301 on the other side. Since the two ends of the compression spring 304 are fixed to the slider 302 and the L-shaped plate 305 respectively, before encountering resistance, pushing the compression spring 304 can drive the L-shaped plate 305 and the brake disc 306 to approach and contact the inner wall of the guide rail 100. The compression spring 304 is compressed, and the guide post 303 slides within the L-shaped plate 305, which in turn causes the brake disc 306 to contact the guide rail 100 and generate friction.

[0049] By setting up the deceleration mechanism 300, the height difference between the bulge and the guide rail 100 is used to push the rotating wheel 313 upward. Then, through cooperation with the pushing component, the brake disc 306 can contact and rub against the inner wall of the guide rail 100, thereby increasing the resistance when the skip 200 is lifted and reducing the speed of the skip 200 when it is lifted, which is lower than the normal speed. This reduces the impact force when the guide wheel 201 collides with the bulge, so that when it is lifted in a steep inclined shaft, it can prevent the car body from overturning due to the front wheel jumping too high, thus improving the safety of coal mine transportation.

[0050] Furthermore, with the setting of the deceleration mechanism 300, in cooperation with the trigger component and the push component, when the bulge height is higher, the sliding plate 311 can rise higher, which in turn makes the push component push the slider 302 to slide a farther distance, and the compression spring 304 is compressed more, which in turn makes the friction between the brake disc 306 and the guide rail 100 greater, so that the deceleration effect of the deceleration mechanism 300 is adapted to the bulge height, ensuring its adaptability during deceleration.

[0051] Furthermore, after the rotating wheel 313 bulges, the deceleration mechanism 300 can reset under the combined action of the return spring 322, the compression spring 304, and gravity. After the deceleration mechanism 300 decelerates the skip 200 for a certain period of time, the skip 200 will gradually return to its normal speed and then perform normal conveying work. At the same time, if a large bulge occurs again, appropriate deceleration and protection work can be carried out again.

[0052] The following describes the working principle and beneficial effects of auxiliary mechanism 400:

[0053] Furthermore, when the rotating wheel 313 rolls on the guide rail 100, if there is mud-like dirt on the guide rail 100, the mud-like dirt will be pressed into the groove 401 through the cooperation of the rotating wheel 313 and the groove 401. Thus, the mud-like dirt on the guide rail 100 can be collected through the groove 401. After each use, the locking pin 405 can be pulled to disengage from the rotating wheel 313, and then the connecting ring 404 can be pulled. The guide rod 403 will drive the scraper 402 to slide in the groove 401 to clean the collected mud-like dirt, thus facilitating the next use. In addition, the auxiliary mechanism 400 can clean and collect some mud-like dirt during use, reducing the amount of dirt accumulated on the guide rail 100, thereby reducing the frequency of bulging and extending the formation cycle, which further reduces the risk during the conveying of the skip 200.

[0054] The embodiments of the present invention have been described above. However, the embodiments are not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the embodiments described above, all of which are within the protection scope of the embodiments described above.
