The specific embodiment
Below in conjunction with drawings and the specific embodiments the present invention is described in further details;
As shown in Figure 1, 2, 3, a kind of dual container semi-mounted rear-dump wagon, comprise vehicle frame 1 and the front compartment 2 and the trunk 3 that arrange respectively along vehicle frame 1 length direction, front elevating ram 4 and rear elevating ram 5 are connected with front compartment and 2 trunks 3 by front lifting platform 21 and the rear lifting platform 31 of being located at front compartment 2 and trunk 3 bottoms respectively.Front compartment 2 and trunk 3 are connected with vehicle frame 1 by front elevating ram 4 and rear elevating ram 5 respectively; Also comprise carriage lifting safety control system 6,
Carriage lifting safety control system 6 comprises fuel tank 7, Hydraulic Pump 8, front elevating ram 4, rear elevating ram 5, front lifting electromagnetism gas control multiway valve 9, rear lifting electromagnetism gas control multiway valve 10 and respectively with front lifting electromagnetism gas control multiway valve 9, the front lifting switch 11 that rear lifting electromagnetism gas control multiway valve 10 connects, front decline switch 12, rear lifting switch 13 and rear decline switch 14 and with front lifting electromagnetism gas control multiway valve 9, the source of the gas 22 that rear lifting electromagnetism gas control multiway valve 10 links to each other, front lifting electromagnetism gas control multiway valve 9, rear lifting electromagnetism gas control multiway valve 10 is connected with fuel tank 7 by Hydraulic Pump 8 respectively, front elevating ram 4 is connected with front lifting electromagnetism gas control multiway valve 9 and rear lifting electromagnetism gas control multiway valve 10 by oil circuit respectively with rear elevating ram 5, front lifting switch 11 and front decline switch 12 electrically connect with front lifting electromagnetism gas control multiway valve 9, rear lifting switch 13 and rear decline switch 14 are connected with rear lifting electromagnetism gas control multiway valve 10, be parallel with electromagnetic relay 15 and rear platform travel switch 16 on the circuit of lifting switch 13 and rear lifting electromagnetism gas control multiway valve 10 after connecting, the front table stroke switch 17 of serial connection on the circuit of decline switch 14 after connecting, table stroke switch 18 and electromagnetic relay 19 before before connection, being serially connected with in the circuit of lifting switch 11.Be equipped with respectively and front lifting switch 11, front decline switch 12, the solenoid hydraulic lock 20 that rear lifting switch 13, rear decline switch 14 are electrically connected at the oil port of front elevating ram 4 and rear elevating ram 5.Fuel tank arranges airfilter 23.
Working process is:
1, after pressing " rear lifting switch 13 ", electric current is through being series at the electromagnetic valve of control lifting on central electromagnetic relay 15 (normally closed) the conducting multiway valve in loop, spool is opened, and promotes cylinder by the high pressure gas from air receiver, and cylinder promotes valve rod makes multiway valve realize lifting function.
2, when giving rise to set angle, electromagnetic induction switch (often opening) is sensed behind the metal closed, connects electromagnetic relay 15 after closed, and the lifting circuit disconnects, and rear platform stops lifting.
3, after pressing " front lifting switch 11 ", be installed on the rear platform travel switch 16 (often opening) at rear platform rear portion, because making switch closure, low level, the rear platform lifting connects, cause electromagnetic relay 15 to be connected, electric current flows through the electromagnetic valve of control lifting on the multiway valve, spool is opened, and promotes cylinder by the high pressure gas from air receiver, and cylinder promotes valve rod makes multiway valve realize lifting function.
4, current platform raising is behind predetermined angular, and after the front table stroke switch 18 (normally closed) that is installed on front platform rear portion was sensed the signal that platform raising puts in place, switch disconnected, and front platform stops lifting.
If the 5 platform control platforms of pressing first rear cabinet fall " rear decline switch 14 ", at this moment, because the front table stroke switch 17 (often opening) that is used for interlocking that is installed on front platform front portion is in off-state, circuit can't be connected, rear platform can't fall, realized in the situation that front platform raising the requirement of the operation that rear platform can not fall.
6, press " front decline switch 12 ", the electromagnetic valve that control descends on the front lifting electromagnetism gas control multiway valve 9, spool is opened, and promotes cylinder by the high pressure gas from air receiver, and cylinder promotes valve rod makes multiway valve realize oil return, and platform falls.
7, after current platform falls, front table stroke switch 17 (often opening) closure, press " after decline switch 14 " after, rear platform falls.So far, whole lifting action is finished.
Certainly, above-mentioned explanation is not to be limitation of the present invention, and the present invention also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present invention, the variation of making, remodeling, interpolation or replacement all should belong to protection scope of the present invention.
