Embodiment Construction

[0012] The present invention will be further described below in conjunction with accompanying drawing.

[0013] Such as figure 1 As shown, a pneumatic monorail crane stepless speed regulation control system includes an air source 1, a cylinder 2, and a main control reversing valve 3. The output pipeline of the air source 1 is divided into two routes, one of which passes through the main control reversing valve The air inlet of valve 3 communicates with cylinder 2, and the other way communicates with the air inlets of speed regulating valve B9 and speed regulating valve D11 respectively;

[0014] There are two branches at the exhaust port of the speed regulating valve B9, one branch communicates with the air inlet of the speed regulating valve A8, and the other branch communicates with the first working port of the motor A12 and the first working port of the motor B13 respectively. The working port is connected, and the exhaust port of the speed regulating valve D11 has two br...

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...
