Description

Technical Field

[0001] The utility model relates to a monorail crane, in particular to a pneumatic gear monorail crane. Background Art

[0002] At present, pneumatic monorail cranes are becoming more and more popular and applied in domestic coal mines as efficient underground auxiliary transportation equipment. Pneumatic monorail cranes have shown their product advantages in coal mine auxiliary transportation, which are safe, fast, efficient, simple to operate and easy to maintain. However, at present, pneumatic monorail cranes are mainly driven by friction wheels, and part of the air source power is consumed in the friction wheel tensioning device, thereby reducing the driving force, which in turn affects the load and climbing angle, and affects the efficiency of transportation. Utility Model Content

[0003] In view of the problems existing in the above-mentioned prior art, the utility model provides a pneumatic gear monorail crane, which has a simple structure, is easy to use, ensures stable power output, increases the climbing angle, and improves the efficiency of transportation.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a pneumatic gear monorail crane, which is slidably mounted on the track of the monorail, including: a pneumatic drive unit, a rail slide, a pneumatic hoist, a rail brake, and a connecting rod. The pneumatic drive unit and the rail brake are slidably mounted on the monorail, and multiple rail slides are slidably arranged on the monorail between the pneumatic drive unit and the rail brake. The rail brake and the rail slide, the rail slide and the rail slide, and the rail slide and the pneumatic drive unit are connected by connecting rods. The pneumatic hoist is installed on the rail slide, and also includes a control device, which is connected to the pneumatic drive unit and the rail brake; the connecting rod is hinged to the pneumatic drive unit, the rail slide, and the rail brake.

[0005] Furthermore, a rack and pinion mechanism is provided between the pneumatic drive unit and the monorail.

[0006] Furthermore, the gears in the rack and pinion mechanism are installed on the monorail, and the gears are installed in the pneumatic drive unit.

[0007] Furthermore, the pneumatic drive unit includes: rollers, mounting frames, pneumatic motors, reducers, and gears. The mounting frame is suspended on the monorail through rollers, the pneumatic motor is connected to the reducer and mounted on the mounting frame, the gear is mounted on the output shaft of the reducer, and the gear is meshed with the rack on the monorail.

[0008] Furthermore, the pneumatic motor and the hanging rail brake are both connected to the air source through a control device, and the control device is a reversing valve or a pneumatic button.

[0009] The beneficial effects of the utility model are: (1) using underground compressed air as a power source, which is convenient to use, safer and low in cost;

[0010] (2) The power comes from the interaction between the driving gear and the rack. The power of the compressed air only acts on the driving gear, avoiding the loss of ineffective wind energy. Compared with the friction wheel pneumatic monorail crane, under the same power source, the driving force is greatly improved, thereby increasing the climbing angle and improving the efficiency of transportation;

[0011] (3) When not driving, the reducer, pneumatic motor, and rack and pinion mechanism can provide a certain braking force to improve safety. BRIEF DESCRIPTION OF THE DRAWINGS
