Man-machine combination type pneumatic crane control handle

Abstract

The invention relates to a man-machine combination type pneumatic crane control handle, and belongs to the technical field of pneumatic balance crane control devices. The man-machine combination typepneumatic crane control handle comprises a valve body, wherein an air inlet, an air outlet and an exhaust port are arranged at the upper end of the valve body; a sliding rod which is connected fixedlyis arranged at the lower end of the valve body; one end of the sliding rod is connected with the valve body, and the other end of the sliding rod is provided with a handle body which is connected slidably; an inner cavity A and an inner cavity B are formed in the interior of the valve body; a communicating through cavity is formed between the inner cavity A and the inner cavity B; a communicatingair outlet channel is formed between the through cavity and the air outlet; air inlet equipment A movably connected with the handle body is arranged in the inner cavity A; a communicating air inlet channel is formed between the air inlet equipment A and the air inlet; air inlet equipment B slidably connected with the handle body is arranged in the inner cavity B; and a communicating exhaust portchannel is formed between the air inlet equipment B and the exhaust port. According to the man-machine combination type pneumatic crane control handle, the structure is simple, the action of a pneumatic crane can be flexibly controlled by moving the handle body, the operation is simple and convenient, errors are not prone to occurring, the stability is improved, the installation is flexible, and the practicability is strong.

Description

technical field [0001] The invention relates to a man-machine combined air suspension control handle, which belongs to the technical field of pneumatic balance suspension control devices. Background technique [0002] Pneumatic balance crane is a kind of lifting equipment powered by compressed air. The lifting, lowering and hovering of the load can be realized by filling, discharging and maintaining the compressed air respectively. The existing control switch controls the lifting and lowering of the load by controlling the on-off of the inflation and exhaust paths respectively through two buttons. It is inconvenient to use, inflexible to control, and inaccurate in positioning; and misoperation may occur, and the lifting process may be reversed. In addition, due to the force of the gas on the key, when the air pressure increases, the force required to press the key also increases, which increases the instability during use. A man-machine combined control device is hereby de...
