When secondary supporting leg continues to stretch out, due to load, necessarily causing oil circuit pressure to raise, act low-pressure relay 404.When microcontroller 51 detects this road signal for low level, secondary leg three-position four-way valve 421 is closed, stops secondary landing leg hydraulic cylinder and stretches out, carrier movement valve 441 is then driven, connecting oil circuit stretches out carrier mobile hydraulic cylinder, promotes the reach of ^ carriers.When carrier is moved to the determination position on assistant support, secondary travel switch 542 is acted.When microcontroller 51 detects this road signal for low level, stop the coil that driving carrier moves valve 441, in the presence of valve inner spring, carrier movement valve 441 return to primitive age position makes carrier mobile hydraulic cylinder connect return line(Step 607).
Microcontroller 51 then drives main leg three-position four-way valve 411, shrinks main landing leg hydraulic cylinder.It is contracted to after the limit, acted by high pressure relay 403, microcontroller 51 receives the road low level signal, close main leg three-position four-way valve 411, driving arm flexible valve 431, support telescopic hydraulic cylinder is shunk, main support is pulled forward, while driving the rod end of carrier mobile hydraulic cylinder to retract(Step 608 w 609).
When main support moves forward to the determination position of carrier, main travel switch 541 is acted due to contact scroll wheel, and microcontroller 51 receives Gai Shi level signals, closes support flexible valve 431, main leg three-position four-way valve 411 is driven, makes the non-loaded stretching of main landing leg hydraulic cylinder.During main supporting leg landing, the extension elongation of forward and backward main supporting leg is inconsistent.The trend that hydraulic cylinder continues to stretch out causes low-pressure relay 404 to act, and microcontroller 51 receives the road low level signal, closes main leg three-position four-way valve 411, and drive pair leg three-position four-way valve 421 shrinks secondary landing leg hydraulic cylinder(Step 610 w 611).
Secondary landing leg hydraulic cylinder is contracted to after the limit, and low-pressure relay 404 is acted.Microcontroller 51 receives the road low level signal, close secondary leg three-position four-way valve 421, driving arm flexible valve 431, assistant support is set to protract, now microcontroller 51 starts the data of detector 522 after reading, after a transition occurs for data, by time delay T seconds set in advance, microcontroller 51 closes support flexible valve 431, assistant support is stopped extension.If transition does not occur for the data of rear detector 522 and anti-collision switch 53 has been acted, or due to branch The frame telescopic hydraulic cylinder length that reaches capacity causes oil circuit pressure to increase, and causes low-pressure relay 4 04 to act, and all microcontroller 51 will be made to perform the operation for stopping assistant support extension(Step 612 is 615).
According to preceding step(The detailed descriptions of 606 w 6 09), under the programme-control of microcontroller 51, device of the invention further completes that the landing of secondary supporting leg, carrier reach, main supporting leg are shunk, main support moves forward this several steps action(Step 616 ^ 619).
Microcontroller 51 now reads the data of preceding detector 52 1 and rear detector 522, and compares their size, if both differences are in the range of tolerance, illustrate that device has arrived at level land, performs Bu Sudden 624;Otherwise following action is performed:Main supporting leg landing, secondary supporting leg shrink.Then, main supporting leg bringing onto load stretches out, the data of detector 522 after microcontroller 51 is read, when the main rear support leg of the as shown by data has extend out to the limit, main leg three-position four-way valve 411 is closed, turns again to perform Bu Sudden 612 (step 620 w 623).
When device has arrived at level land, microcontroller 51 sends control signal, withdraws the supporting leg stretched out, completes whole top bar processes(Step 624 ^ 625).
When main supporting leg bringing onto load rises, microcontroller 51 constantly reads the data of preceding detector 521 and rear detector 522, it was found that the extension elongation of main front leg strut and main rear support leg it is uncoordinated and more than allowable error when, control main foreleg switch valve 4111 or main back leg switch valve 4112, it is adjusted correspondingly, 4 slow-witted horizontalities of the card device in uphill process.
Refer to shown in Figure 16, and combine the method for getting out of a predicament or an embarrassing situation that Figure 15, Figure 14 and Fig. 13 illustrates the present invention.When microcontroller 51, which detects mode switch 582, provides signal of getting out of a predicament or an embarrassing situation for low level, sending control signal drives main leg three-position four-way valve 411 to act, connecting oil circuit makes four main non-loaded stretchings of landing leg hydraulic cylinder and lands, then bringing onto load continues to stretch out, microcontroller 51 constantly reads the data of preceding detector 521 and rear detector 522, when the wheel ground slightly away of device, least restrictive height value previously given in a program is reached(Hereinafter referred to as lower bound)When, close the main (Bu Sudden 7 01 of leg three-position four-way valve 411).
The step of follow-up step (702 ^ 725) is with above-mentioned Figure 15((602 625) implementation process base mesh it is same, difference therein is step 723 and step 623.In above-mentioned Figure 15 step 623, main supporting leg bringing onto load rises;Become in step 72 3 and decline into main supporting leg bringing onto load(Main landing leg hydraulic cylinder shrinks), when main rear support leg, which declines, reaches lower bound, that is, stop.
