Problems solved by technology

However, in practical applications, it often occurs that the fork 104 of the forklift is lowered to the ground without first operating the manual hydraulic reversing valve 102, and directly operates the manual pneumatic reversing valve 111 to turn off the engine, so that the parking safety of the forklift cannot be guaranteed.

Abstract

A flameout and fork linkage device of a forklift comprises a fork lifting oil cylinder, a hydraulic pump, a manual hydraulic reversing valve, an oil tank, a fork, an air pocket, a manual pneumatic reversing valve, a flameout air cylinder, a pressure switch, a power source, an electromagnetic hydraulic reversing valve, a first one-way valve and a second one-way valve. An executing port A of the manual pneumatic reversing valve communicates with the flameout air cylinder and the pressure switch. The electromagnetic hydraulic reversing valve is electrically connected with the power source. The pressure switch is connected between the electromagnetic hydraulic reversing valve and a circuit of the power source. An oil outlet of the hydraulic pump communicates with an oil inlet P of the electromagnetic hydraulic reversing valve and an oil inlet P of the manual hydraulic reversing valve. An executing port A of the manual hydraulic reversing valve communicates with the second one-way valve. The second one-way valve communicates with a rod cavity of the fork lifting oil cylinder. An executing port A of the electromagnetic hydraulic reversing valve communicates with the first one-way valve.The first one-way valve communicates with a rod cavity of the fork lifting oil cylinder. By the adoption of the flameout and fork linkage device, safe parking of the forklift can be guaranteed.

Description

technical field [0001] The invention relates to a forklift, in particular to a flameout and fork linkage device of the forklift. Background technique [0002] Such as figure 1 and figure 2 As shown, when the driver needs to stop after using the forklift, it is necessary to operate the manual hydraulic reversing valve 102 of the fork mechanism of the forklift first, so that the fork lift cylinder 100 is lowered to lower the fork 104 to the ground, and then the forklift is turned off. The manual pneumatic reversing valve 111 of the mechanism makes the flameout cylinder 112 act and the engine is flamed out, so that the parking safety of the forklift can be guaranteed. However, in practical applications, it often occurs that the fork 104 of the forklift is lowered to the ground without first operating the manual hydraulic reversing valve 102, and directly operates the manual pneumatic reversing valve 111 to turn off the engine, so that the parking safety of the forklift canno...
