叉车的熄火与货叉联动装置
摘要：
一种叉车的熄火与货叉联动装置，包括货叉升降油缸、液压泵、手动液压换向阀、油箱、货叉、气包、手动气压换向阀、熄火气缸、压力开关、电源、电磁液压换向阀、第一单向阀和第二单向阀；手动气压换向阀的执行口A口分别与熄火气缸和压力开关连通；电磁液压换向阀与电源电连接，压力开关连接在电磁液压换向阀与电源的电路之间，液压泵的出油口分别与电磁液压换向阀的进油口P口和手动液压换向阀的进油口P口连通；手动液压换向阀的执行口A口与第二单向阀连通，第二单向阀与货叉升降油缸的有杆腔连通；电磁液压换向阀的执行口A口与第一单向阀连通，第一单向阀与货叉升降油缸的有杆腔连通。本发明可保证叉车的停放安全。
摘要（英）：

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.
