Stepless speed regulating control system of pneumatic monorail crane

Abstract

The invention provides a stepless speed regulating control system of a pneumatic monorail crane. The stepless speed regulating control system consists of an air source processing system, a speed regulating reversing handle, a pneumatic motor power system and a pressure flow speed regulating system, wherein the air source processing system consists of an oil-water separator, a pressure reducing valve, a filter and an atomized lubricator; the speed regulating reversing handle is integrated by control handles of two pressure adjusting valves and an auxiliary reversing valve; the pressure flow speed regulating system consists of four speed regulating valves; and compressed air is supplied to a pneumatic motor, a cylinder and the speed regulating reversing handle for use by the air source processing system. The control system can precisely control the air pressure and flow to realize the stepless speed regulating power walking and the brake stopping of the pneumatic monorail crane, and can realize slow starting and braking to prevent quick starting / stopping phenomenon, so that the wear of a brake friction wheel is reduced, the monorail crane can operate more smoothly, and the stepless speed regulating purpose of the monorail crane can be realized; and the stepless speed regulating control system improves the operation reliability and safety of the monorail crane.

Description

technical field [0001] The invention relates to a monorail crane, in particular to a stepless speed regulation control system for a pneumatic monorail crane. Background technique [0002] The pneumatic monorail crane currently used in China has no speed regulation function. The operating handle can only limit the on and off of the gas, and cannot control the change of the gas volume and air pressure. Therefore, the phenomenon of quick start and quick stop occurs when starting and braking, which increases the friction. At the same time, the operation of the main engine of the monorail crane is prone to instability, and it is easy to cause impact on the monorail crane and hoisting parts, which may easily cause safety accidents. Contents of the invention [0003] Aiming at the problems existing in the above-mentioned prior art, the present invention provides a stepless speed regulation control system for a pneumatic monorail crane, which uses an air source to provide power fo...
