Pneumatic monorail crane

Abstract

The invention discloses a pneumatic monorail crane. A traction machine head comprises a machine head frame and an air inlet pipeline mounted in the machine head frame; one end of the air inlet pipeline is connected with an air source, and a pipeline filter, a one-way valve and an air path interlocking protection device are sequentially mounted at the other end of the air inlet pipeline; the air path interlocking protection device outputs the air source to a master control unit, a pressure loss and pressurizing balance device and a low-pressure starting device, and the master control unit is in control connection with two pneumatic motors, the pressure loss and pressurizing balance device, the low-pressure starting device, and a control handle, wherein the two pneumatic motors, the pressure loss and pressurizing balance device and the low-pressure starting device are mounted in the machine head frame, and the control handle is located outside the machine head frame and connected through a pipeline; and the pressure loss and pressurizing balance device is connected with a brake cylinder of a brake mechanism, and the pressure loss and pressurizing balance device and the low-pressure starting device each comprise a pneumatic balance assembly. Any fluctuation of the air source pressure ranging from 0.25 MP to 0.8 MP is met, and the pneumatic monorail crane completely meets the underground complex working condition; and the pneumatic monorail crane has functions of low-pressure starting, wide-pressure work, pressure loss protection, strong climbing energy and the like and is safe, reliable and long in service life.

Description

technical field [0001] The invention relates to a monorail crane, in particular to a pneumatic monorail crane. Background technique [0002] The monorail crane is a kind of crane tool. It uses a special I-beam hanging above the roadway as the track, and the hanging vehicles with various functions are connected into a train group, and the traction equipment is used to pull the system running along the track. Its traction power can be provided by wire rope, diesel engine, battery or pneumatic device. Because the monorail crane has a small section of the machine and a high utilization rate of the section space of the roadway, it is used for continuous non-reloading transportation of horizontal and inclined roadways. The transport load is not limited by the floor conditions and can run on various vertical curves, flat curves and complex curves. , Auxiliary transportation from the mining area yard to the working face without reloading, auxiliary transportation that connects the ...

Problems solved by technology

[0003] Due to the different traction heads, its use is also different. For example, diesel engine or electric motor is used for traction, which has good flexibility and unlimited transportation distance. It can transport personnel, materials and equipment to any place needed, and has strong climbing ability. The maximum inclination angle of diesel locomotives can reach 30°, and that of battery locomotives can reach 15°. However, the exhaust gas emitted by diesel monorail cranes is polluted, smelly, and noisy. Battery locomotives require power supply, which affects underground use, and the above-mentioned power has costs in underground mines. Too high, underground safety requires explosion-proof, unreliable braking and many other problems need to be solved

[0004] Pneumatic monorail cranes work with the energy provided by the underground air pressure pipe. Since the underground air source follows the roadway, the power is available everywhere. However, there is a problem of stability in the pressure provided by the air pressure pipe. The existing pneumatic monorail The starting pressure of the crane needs to be 4KG or above, which limits the promotion of pneumatic monorail cranes, and the existing pneumatic monorail cranes still lose control or control failure (auxiliary holding Aging of brake springs) and many other problems such as the maximum inclination angle is too low (15° or lower)
