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.
