[0001] This utility model relates to the field of underground coal mining technology, and in particular to an anti-derailment device for a monorail crane locomotive in an underground coal mine. Background Technology
[0002] Underground mining refers to a mining method in coal mining that contrasts with open-pit mining. Compared to open-pit mining, underground mining technology is much more difficult, but since most coal mines are buried underground, underground mining is a necessary method. The application of underground mining technology must be adapted to the geology of the coal mine and the distribution of coal seams, and a mining plan must be developed in advance, determining the application of equipment and support methods.
[0003] When transporting materials mined underground in coal mines, it is often necessary to use underground monorail cranes. The monorail crane moves along the I-beams by rotating rollers. However, if the monorail crane is not properly maintained after long-term operation, it may derail.
[0004] Therefore, it is necessary to provide a new anti-derailment device for monorail cranes in coal mines to solve the above-mentioned technical problems. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0022] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 A schematic diagram of a preferred embodiment of the anti-derailment device for a monorail crane locomotive in a coal mine provided by this utility model; Figure 2 Another structural schematic diagram of the anti-derailment device for a monorail crane locomotive in a coal mine provided by this utility model; Figure 3 for Figure 1 The diagram shows the structure of the anti-derailment mechanism.
[0023] Figure 4 for Figure 3 The diagram shows the explosive structure of the anti-derailment mechanism. The anti-derailment device for a monorail crane in a coal mine includes a track body 1, on which an anti-derailment mechanism 3 is installed.
[0024] The anti-derailment mechanism 3 includes two fixing plates 301, one on each side of the track body 1. A placement plate is installed between the two fixing plates 301, and the two fixing plates 301 are fixedly connected by the placement plate. The placement plate is located below the track body 1. An anti-derailment groove 6 is provided at the bottom of the track body 1. A slider 302 is fixedly installed on the placement plate and slides inside the anti-derailment groove 6 to limit the anti-derailment mechanism 3. Two sets of rotating wheels 304 are rotatably arranged on one side of each of the two fixing plates 301. The two sets of rotating wheels 304 are rotatably arranged inside the track body 1. A locking block 5 is fixedly installed on the track body 1. A locking groove 305 is provided in the middle of the rotating wheel 304. The locking block 5 is located inside the locking groove 305 and can limit the rotating wheel 304, so that the rotating wheel 304 is in a stable state when rotating. A connecting plate 306 is fixedly installed in the middle of the two fixing plates 301. A traction column 307 is fixedly installed on one side of the connecting plate 306. A guide groove 2 is provided on the body 1. A traction column 307 is slidably disposed inside the guide groove 2. The diameter of the guide groove 2 is larger than the diameter of the traction column 307. The outer side of the traction column 307 is in contact with the inner wall of the guide groove 2 to provide a pulling effect on the anti-derailment mechanism 3 and improve the stability of the anti-derailment mechanism 3 during movement. Support plates 303 are fixedly installed at the bottom of both fixed plates 301. Connectors 4 are provided on the outer side of the support plates 303. Specifically, when the anti-derailment device is used, the rotating wheel 304 rotates and drives the outer fixed plate 301 to move. The movement of the fixed plate 301 drives the lower connector 4 to move, thereby driving the crane to move on the track body 1. During the movement, the locking block 5 limits the rotating wheel 304. At the same time, the traction column 307 located on one side slides inside the guide groove 2, thereby providing a pulling effect on the anti-derailment mechanism 3. The slider 302 set on the support plate 303 slides inside the anti-derailment groove 6, thereby improving the stability of the anti-derailment mechanism 3 during movement.
[0025] Furthermore, a stabilizing plate 308 is fixedly installed on one side of each of the two support plates 303. The connector 4 is located on the outside of the stabilizing plate 308. Threaded holes 8 are provided on both the connector 4 and the stabilizing plate 308. A limit bolt 12 is rotatably provided inside the threaded hole 8. The connector 4 and the fixing plate 301 are fixedly connected by the limit bolt 12 for installing the connector 4. The connector 4 is provided with a insertion groove 11. The support plate 303 is located inside the insertion groove 11. Fastening holes 9 are provided on both the connector 4 and the support plate 303. Fixing bolts 10 are provided inside the fastening holes 9. The support plate 303 and the connector 4 are fixedly connected by the fixing bolts 10. An installation groove 7 is provided in the middle of the connector 4. A crane is installed inside the installation groove 7. When installing the crane, the connector 4 is installed at the bottom of the anti-derailment mechanism 3, which facilitates the overall installation of the crane and the disassembly of the crane, while improving the stability of the crane during installation.
[0026] The working principle of the anti-derailment device for monorail cranes in coal mines provided by this utility model is as follows:
[0027] When the anti-detachment device is first used, the rotating wheel 304 rotates, causing the outer fixing plate 301 to move. The movement of the fixing plate 301 causes the lower connector 4 to move, thereby causing the crane to move on the track body 1.
[0028] During the movement, the locking block 5 limits the rotation wheel 304, while the traction column 307 located on one side slides inside the guide groove 2, thereby pulling the anti-derailment mechanism 3. The slider 302 set on the support plate 303 slides inside the anti-derailment groove 6, thereby improving the stability of the anti-derailment mechanism 3 during movement.
[0029] During the installation of the crane, a connector 4 is installed at the bottom of the anti-derailment mechanism 3 to facilitate the overall installation of the crane.
[0030] Compared with related technologies, the anti-derailment device for monorail cranes in coal mines provided by this utility model has the following beneficial effects:
[0031] This utility model provides an anti-derailment device for a monorail crane in a coal mine. Through the anti-derailment mechanism 3, during use, the rotating wheel 304 drives the outer fixing plate 301 to move. The movement of the fixing plate 301 drives the lower connector 4 to move, thereby moving the crane on the track body 1. During the movement, the locking block 5 limits the rotation wheel 304, while the traction column 307 on one side slides inside the guide groove 2, thus pulling the anti-derailment mechanism 3. Furthermore, the slider 302 on the support plate 303 slides inside the anti-derailment groove 6, thereby improving the stability of the anti-derailment mechanism 3 during movement. Therefore, it provides good protection for the crane and effectively prevents the monorail crane from derailing after long-term operation.
