During the raising switch of fork truck, contactor 914, which is powered, causes lifting motor 911 is powered to rotate and drive gear pump 912 to work, gear
The inlet port of pump 912 connects the fuel tank outside oil cylinder 913 by fuel sucking pipe 9161, and the other end connects oil cylinder by flowline 9162
High pressure chest inside 913, therefore realize the raising action of the plunger 915 of oil cylinder 913；Check valve is provided with inside flowline 9162
9163, when lifting motor 911 is stopped, check valve 9163 realizes sealing function, it is to avoid the oil of high pressure chest is back to fuel tank；When
During decline, lowering valve 9166 will be touched by pulling the decline knob in operation handle 80 so that high pressure oil discharge passage 9164 and decline
The UNICOM of drainback passage 9165, i.e. high pressure chest and fuel tank UNICOM, are realized by the weight of goods or the own wt of body frame structure for automotive 10
Down maneuver.
When this fork truck is set to electronic decline, preferably lowering valve 9166 is set to plugged electric magnet valve；When being set to hand
During dynamic decline, lowering valve 9166 is preferably set to manual lowering valve, plugged electric magnet valve is substituted with manual lowering valve, half is realized
Electronic control, i.e., electronic lifting and Manual descending, applicability are wide, practical.
Further, overcurrent protection structure is additionally provided with this fork truck, the outlet of preferably flowline 9162 is also linked with
Overload protection passage 9167, the overload protection passage 9167 is by overloading drainback passage 9168 with declining drainback passage 9165
It is logical, and it is provided with safety valve 9169 between overload protection passage 9167 and overload drainback passage 9168.
Used during raising as overload occurs in vehicle, then hydraulic oil will open peace by the top of overload protection passage 9167
Full valve 9169, then enter fuel tank by overloading drainback passage 9168 and decline drainback passage 9165 and realize that safeguard protection is acted on, work
Make relatively reliable, safety.
The preferable layout of manual pump configuration 92 in this case is as follows：Manual pump configuration 92 includes the hand being connected with operation handle 80
Dynamic pump group 921, the fuel tank for being built-in with the oil cylinder 922 of high pressure chest, being arranged on the periphery of oil cylinder 922, further preferably in fuel tank upper outside
Oil filler provided with opening inclination upward, and it is provided with plug in oil filler；The manual pump group 921 includes pumping cylinder and activity is installed
In in pumping cylinder and the pump core that reciprocally moves along a straight line, the bottom of oil cylinder 922 is connected with body frame structure for automotive 10, on the oil cylinder 922
Portion to middle part is movably installed with plunger 923, and the high pressure chest is linked with high pressure oil discharge passage 9241, and the fuel tank is linked with decline
Drainback passage 9242, and decline drainback passage 9242 be connected by Manual descending valve group 9243 with high pressure oil discharge passage 9241,
The middle part of Manual descending valve group 9243 is provided with check valve 9244, and the outlet of the pumping cylinder passes through interface channel 9245 and check valve 9244
It is connected.
Further, safety valve 9246 is additionally provided with interface channel 9245, the outlet of the safety valve 9246 passed through
Drainback passage 9247 is carried with declining the UNICOM of drainback passage 9242.
In the present invention, the setting of manual pump configuration 92 is then to remove lifting motor on the basis of electronic pump configuration 91
911 and gear pump 912, manual pump group 921 is further added by, the function of Manual lift start is realized, so that reducing cost improves product sexual valence
Than；The reciprocating motion of pump core in manual pump group 921 can be realized during work, during the operation handle 80 for the fork truck that fluctuates, pump core is moved back
When going out, pumping cylinder internal pressure reduces to be opened so as to which the steel ball of check valve 9244 be inhaled, and the oil of fuel tank internal is by declining drainback passage
9242 flow into inside pumping cylinder, and when pump core is pushed, the increase of pumping cylinder internal pressure promotes steel ball sealing fuel tank side, and oil pressure is entered
High pressure oil discharge passage 9241 enters high pressure chest, so as to realize the raising of plunger 923；When overload of vehicle, the hydraulic oil inside pumping cylinder
Push open safety valve 9246 by overload drainback passage 9247 and decline drainback passage 9242 flow back to fuel tank realize safeguard protection act on；
