Multi-way valve operation mechanism for fork lift

Abstract

The invention relates to a new multi-way valve operation mechanism for forklift, solving the problem that the operator is easy to feel fatigue because of the prior multi-way valve operation mechanism, which comprises a multi-way valve and a rectangle framework support, wherein one side of the rectangle framework support is connected with a hinged frame by a shaft; the cross section of the hinged frame is angle steel shape; the horizontal side edges of the hinged frame are respectively movably connected with two piston connecting rod by a plurality of short pins; the vertical side edges of the hinge frame are respectively connected with two connecting rods by two respective swivel pins; the other ends of the two connecting rods are respectively connected with a forward-backward inclined control stick and a lifting control stick; the two control sticks are arranged at the central section of the rectangle frame support; a locking connecting piece is arranged on the other end of the rectangle frame support. The multi-way valve operation mechanism design is positioned on the most comfortable place for right hand, the hood at the right side of seat, and the place of the invention positioned is as high as the waist height of sitting posture of driver; the assembly and disassembly operation can be performed by arms in the most natural state, and the arms are needed to protrude forwards, which meets the requirement of man-machine engineering in maximal degree.

Description

technical field [0001] The invention relates to a multi-way valve operating mechanism of a forklift. Background technique [0002] The multi-way valve joystick is the signal source for forklift loading and unloading, including lifting, lowering, tilting forward and backward, sideways, rotating, etc. The driver's right hand should basically hold the joystick all the time to realize the loading and unloading actions of the forklift. However, in view of the characteristics of the battery forklift, the battery under the seat needs to be replaced frequently, and the seat cover often needs to be turned up, so the valve control structure of the battery forklift is generally placed at the front of the instrument frame, and the control handle is directly connected to the multi-way valve. The piston rod makes the control handle located in front of the driver. From the perspective of ergonomics, if the arm stretches forward for too long, it is easy to cause fatigue to the driver. Con...
