Multi-connecting-rod type multi-way valve operation mechanism

Abstract

The invention provides a multi-connecting-rod type multi-way valve operating and control mechanism. An operation handle is connected with a multi-way valve through a four-direction double-connecting-rod mechanism, the goal of exerting vertical four-direction executing commands in the same plane on the operation handle is achieved, and four control loops of the multi-way valve are controlled; the operation handle is simultaneously connected with the multi-way valve through a rotating connecting rod mechanism, the goal of exerting two-direction (clockwise and anticlockwise) executing commands in the same plane on the operation handle is achieved, and the two control loops of the multi-way valve are controlled. The multi-connecting-rod type multi-way valve operating and control mechanism has the advantages that the effect of doing six command executing actions on the operation handle can be realized, the action executing components are respectively and correspondingly controlled, the six operation actions are completed, more operation commands can be realized on the same operation handle, the operation and the control of the machine provided with the operation handle are convenient; the structure is compact, and the operation control is simplified.

Description

technical field [0001] The invention relates to a multi-link multi-way valve control mechanism, which is applied to a mechanical action execution command input mechanism that needs to perform various actions, and belongs to the mechanical field. Background technique [0002] At present, the traditional multi-way valve control mechanism can only control the action in four directions (that is, two links) with one handle. The control of other links requires additional joysticks. The structure is scattered and the operation is cumbersome. The operator needs to Familiarity with multiple joysticks increases the difficulty of operating the machine and brings great difficulty to the operator. In addition, the joystick needs to be replaced when using it. There will be a time difference in the input of the action execution command, which will affect the operator's There are greater requirements for replacement speed, eyesight, physical strength and coordination.

Problems solved by technology

[0002] At present, the traditional multi-way valve control mechanism can only control the action in four directions (that is, two links) with one handle, and the control of other links needs to be added. The control handle has a scattered structure and is cumbersome to operate. The operator needs to be familiar with multiple control handles, which increases the difficulty of operating the machine and brings great difficulty to the operator. In addition, the control handle needs to be replaced during use. There will be a time difference for the input of action execution commands, which has great requirements on the operator's replacement speed, eyesight, physical strength and coordination
