AI Technical Summary
When existing monorail cranes are used in mines, the accumulation of coal dust and water vapor at the welded joints causes the wheels to bounce frequently, affecting the stability of goods and the lifespan of the rails, posing a safety hazard.
A protective mechanism was designed that uses protruding impurities to push a trigger block, which, through the cooperation of a rotating wheel, a pull rope, and a guide roller, pulls the impact plate to slide and remove the protruding impurities. At the same time, an auxiliary mechanism blows airflow through an airbag nozzle to push away the impurities, ensuring the track is clean.
It effectively reduces the interference of protruding impurities on the transport vehicle body, improves the safety and continuity of the track, reduces the risk of deformation and breakage, and enhances the safety of monorail operation.

Due to the humid and dusty environment in the mine, and the accumulation of coal dust and water vapor in the welded concave and convex parts for a long time, a long strip-shaped protrusion is formed. When the wheels pass through, they will frequently jump up at the track connection, not only causing the goods to shake and fall, but also the frequent vibration when jumping up affecting the service life of the track, and even causing the connection to deform or break, affecting the safety of the monorail crane during use.

[0030] The working principle of all the above embodiments is as follows: Initial state: When the torsional spring 312 is in a normal state, the trigger block 309 is perpendicular to the inner wall bottom of the track body 100 and is at an appropriate distance from the track body 100, as shown in the figure, at this time the pull rope 311 is not pulled, and at the same time the return spring 306 is in a normal state, and the air bag 403 is in a compressed state.

[0032] The working principle of the protection mechanism 300 and its beneficial effects are as follows: When the conveying vehicle body 200 travels on the track body 100, when passing through the connection of the track body 100, if the accumulated impurities reach a set height, when the conveying vehicle body 200 drives the protection mechanism 300 to pass through, the protruding impurities will push the trigger block 309 to move in the direction of the impact plate 304, and then use the pushing of the protruding impurities to make the rotating wheel 308 rotate at the same time, the torsional spring 312 is twisted, and when the rotating wheel 308 rotates, under the guidance and limiting of the guide roller 310, the impact plate 304 can be pulled to slide away from the trigger block 309 through the pull rope 311, and the guide column 305 is also pulled to slide on the guide plate 303, and the reset spring 306 is compressed, and then when the trigger block 309 continues to advance and is pushed by the protruding impurities, after the trigger block 309 rotates by a certain angle, it will gradually be staggered with the protruding impurities, at this time, the protruding impurities are located between the trigger block 309 and the impact plate 304, and then under the rotation of the torsional spring 312 and the rebound of the reset spring 306, the impact plate 304 is quickly reset and hits the protruding impurities, through the flat setting of the impact plate 304 and the setting of the toothed block 3041, the impurities can be more easily crushed and separated from the track body 100.
[0033] Through the setting of the protection mechanism 300, the resistance generated by the protruding impurities is used to push the trigger block 309, and then under the cooperation of the rotating wheel 308, the pull rope 311 and the guide roller 310, the impact plate 304 is pulled to slide and store energy, and finally hits the protruding impurities, and the physical height of the impurity accumulation is used to automatically trigger the cleaning action, so as to greatly reduce the interference of the protruding impurities at the connection to the conveying vehicle body 200 when traveling, increase the safety of the track body 100 and the conveying vehicle body 200 when in use, and reduce the risk of deformation or even breakage of the connection of the track body 100.
[0034] Through the setting of the protection mechanism 300, after completing the cleaning of the protruding impurities at the connection, under the cooperation of the torsional spring 312 and the reset spring 306, the trigger block 309 and the impact plate 304 can be quickly reset, preparing for the next cleaning work, so that when the track body 100 is formed by connecting multiple tracks on the same side, the protruding impurities at the connection can be continuously treated through the reset, thereby ensuring the continuity of the work.
[0035] The working principle and beneficial effects of the auxiliary mechanism 400 are as follows: Further, when the impact plate 304 is subjected to the pulling of the pulling rope 311 to accumulate force, the guide column 305 is away from one end of the air bag 403, at this time the air bag 403 rebounds and returns to the normal state, until the impact plate 304 device protrudes the impurities, the guide column 305 resets, at this time the guide column 305 extrudes and pushes the air bag 403 to compress, and then makes the gas in the air bag 403 pass through the connecting pipe 404 and blow out from the nozzle 405, and through the inclined setting of the bottom of the nozzle 405, the impurities separated from the track body 100 can be pushed to the outside of the track body 100 by the inclined airflow, further reducing the interference of the impurities to the running of the conveying vehicle body 200, and greatly avoiding the problem of secondary accumulation caused by the impurities being crushed by the rollers of the conveying vehicle body 200, increasing the cleaning strength of the protection mechanism 300 to the impurities, and further improving the safety of the conveying vehicle body 200 passing through the connection of the track body 100.
