[0002] In recent years, monorail crane locomotives have developed rapidly as a new safe and efficient auxiliary transportation system. They are being adopted by more and more coal mining enterprises and have become the preferred equipment for auxiliary transportation in coal mines. Compared with traditional ground rail transportation, monorail cranes are not restricted by the roadway floor. Complex roadway conditions such as muddy floors, undulating slopes, etc. can better highlight the advantages of monorail crane equipment. Pneumatic monorail crane is a dispatching monorail crane product, which is a beneficial supplement to large monorail crane equipment. It uses tunnel compressed air as its power source. The locomotive is small in size and is suitable for tunnels with narrow space and short-distance transportation. The pneumatic monorail crane has greatly improved the phenomenon of manual handling of materials in connecting tunnels and working surface ends. However, the existing monorail crane will slip due to factors such as large transportation slopes and harsh conditions. Some monorail cranes that move through the meshing of gears and racks will run for a long time, and the friction between the gear and rack will cause jamming. It is inconvenient for staff to frequently add lubricating oil to the meshing of gears and racks, which will cause friction between the gear and rack for a long time and reduce their service life.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-6 , the utility model provides an embodiment: a gear monorail crane driving device, including a mounting frame 1 and an I-shaped steel 2;

[0022] Four groups of load-bearing wheels 3 are symmetrically installed on the front and rear ends of the upper end of the mounting frame 1. The four groups of load-bearing wheels 3 are located on the front and rear sides of the I-shaped steel 2. A driving motor 4 is fixedly installed on the front side of the lower end of the mounting frame 1. A first movable groove 5 is opened in the lower end of the mounting frame 1. A gear 6 is rotatably installed in the first movable groove 5. The gear 6 is fixedly connected to the output shaft of the driving motor 4. A rack 7 is provided at the lower end of the I-shaped steel 2. The rack 7 is meshed with the gear 6. Four groups of limit blocks 8 are symmetrically installed on the upper end of the mounting frame 1. The four groups of limit blocks 8 are fitted and installed on the lower end of the I-shaped steel 2. An oil injection assembly is provided in the lower end of the mounting frame 1, and the opening at the left end of the oil injection assembly is connected to the left side of the lower end of the first movable groove 5. A quantitative assembly is provided in the mounting frame 1, and the rear end of the quantitative assembly is inserted in the oil injection assembly. The device adds lubricating oil into the oil injection assembly, and then when the output shaft of the driving motor 4 drives the gear 6 to rotate on the rack 7, the quantitative assembly opens and closes with the rotation of the output shaft of the driving motor 4, so that the lubricating oil in the oil injection assembly flows out into the first movable groove 5, so that the lubricating oil is applied to the surface of the gear 6 and the rack 7;

[0023] Furthermore, fixed blocks 9 are symmetrically installed on the upper end of the mounting frame 1, and bristles 10 are installed on the upper sides of the two groups of fixed blocks 9. The two groups of bristles 10 are in contact with the rack 7. This structure cleans dirt on the surface of the rack 7 through the two groups of fixed blocks 9 and the two groups of bristles 10 to prevent the surface of the rack 7 from being contaminated with too much dirt, which may cause the gear 6 to jam when rotating.

[0024] Furthermore, the oil filling assembly includes an oil storage tank 11 and an oil pipe 12. The oil storage tank 11 is opened in the lower end of the mounting frame 1, and the oil pipe 12 is opened in the lower end of the mounting frame 1. The upper end opening of the oil pipe 12 is connected to the lower end opening of the oil storage tank 11, and the lower end opening of the oil pipe 12 is connected to the lower end of the first movable groove 5. The upper end opening of the oil storage tank 11 is on the rear side of the mounting frame 1. This structure injects the lubricating oil from the upper end opening of the oil storage tank 11 into the oil storage tank 11, and the lubricating oil in the oil storage tank 11 flows out from the oil pipe 12 into the first movable groove 5, so that the surface of the gear 6 is contaminated with the lubricating oil when it rotates in the first movable groove 5.

[0025] Furthermore, the lower end of the oil storage tank 11 and the upper end of the oil pipe 12 are both funnel-shaped, and the opening of the lower end of the oil storage tank 11 is consistent in diameter with the opening of the upper end of the oil pipe 12. This structure allows the lubricating oil in the oil storage tank 11 to flow out into the oil pipe 12 to the maximum extent according to the opening shapes of the lower end of the oil storage tank 11 and the upper end of the oil pipe 12, thereby avoiding the retention of lubricating oil in the oil storage tank 11.

[0026] Further, the quantitative component includes a second movable groove 13 and a fixed ring 14, a second movable groove 13 is opened in the front end of the mounting frame 1, the fixed ring 14 is fixedly installed on the output shaft of the driving motor 4, and a dial plate 15 is fixedly installed on the left side of the fixed ring 14, so that the fixed ring 14 and the dial plate 15 are in the second movable groove 13, a third movable groove 16 is opened in the lower end of the mounting frame 1, a slide plate 17 is movably inserted in the third movable groove 16, a push plate 18 is fixedly installed at the front end of the slide plate 17, a spring 19 is installed in the rear end of the third movable groove 16, a through hole 20 is opened at the rear end of the slide plate 17, and the through hole 20 is at At the front side of the connection between the oil storage tank 11 and the oil delivery pipe 12, the structure drives the fixed ring 14 and the paddle plate 15 to rotate when the output shaft of the driving motor 4 drives the driving plate 15, and the rotation of the paddle plate 15 squeezes the slide plate 17 and the push plate 18 to slide backward, and the through hole 20 on the slide plate 17 is aligned with the connection between the oil storage tank 11 and the oil delivery pipe 12, so that the lubricating oil in the oil storage tank 11 can flow into the oil delivery pipe 12, and move away with the rotation of the paddle plate 15, the slide plate 17 and the through hole 20 continuously move back and forth in the third movable groove 16, so as to facilitate the quantitative and regular outflow of the lubricating oil in the oil storage tank 11, and facilitate the application of lubricating oil to the surfaces of the gear 6 and the rack 7.

[0027] Furthermore, the upper side of the push plate 18 is inclined, the rear end of the push plate 18 is higher than the front end, and the push plate 18 is inserted into the left end of the second movable groove 13. According to the shape of the upper side of the push plate 18, this structure enables the fixed ring 14 to rotate and squeeze the push plate 18 when the paddle plate 15 is driven to rotate, and the push plate 18 can slide backward due to the squeezing of the paddle plate 15.

[0028] Working principle: When lubricating oil is applied to the gear 6 in the first movable groove 5, Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the lubricating oil is injected into the oil storage tank 11 from the upper opening of the oil storage tank 11. After the lubricating oil is injected into the oil storage tank 11, the output shaft of the driving motor 4 drives the gear 6 to rotate in the first movable groove 5. The gear 6 rotates and moves on the rack 7, thereby driving the mounting frame 1 to move on the I-shaped steel 2, and the output shaft of the driving motor 4 drives the fixing ring 14 and the paddle plate 15 to rotate in the second movable groove 13. When the paddle plate 15 rotates, it squeezes the push plate 18. The push plate 18 is squeezed and drives the slide plate 17 to slide backward in the third movable groove 16. When the slide plate 17 slides backward, it squeezes the spring 19, and the through hole 20 at the upper end of the slide plate 17 is aligned with the connection between the oil storage tank 11 and the oil pipeline 12. The lubricating oil in 11 flows out through the through hole 20 into the oil delivery pipe 12, and the lubricating oil in the oil delivery pipe 12 flows into the first movable groove 5. The lubricating oil in the first movable groove 5 is stained on the surface of the gear 6 as the gear 6 rotates in the first movable groove 5. When the gear 6 rotates and meshes with the rack 7, the lubricating oil is also stained on the surface of the rack 7, thereby achieving the effect of smearing lubricating oil on the surfaces of the gear 6 and the rack 7. After the paddle 15 is rotated and moved away, the slide plate 17 and the push plate 18 are popped forward and reset under the action of the restoring force of the spring 19, and the through hole 20 can be removed from the connection between the oil storage tank 11 and the oil delivery pipe 12, so as to control the amount of lubricating oil injected. The above is the entire working principle of the utility model.
