Pivoted arm 1 rotates down folding and closes at revoliving arm 1.
In above-described embodiment, revolution detection components 6 include two thirds close switch 61 and two third detection plates 62, are returned
Turning the method that detection components 6 judge whether revoliving arm 1 turns round reset is：First determine whether two thirds have letter close to switch 61
Number, if one of third has signal close to switch 61, another third does not have signal close to switch 61, then controls revoliving arm 1
It is rotated accordingly to the third of not signal close to the direction of switch 61, until two thirds have signal close to switch 61, this
When judgement revoliving arm 1 revolution reset.
The operations such as above-mentioned two embodiment can be made to stretch by a key operation, rotated, pitching are sequentially completed, and are enhanced
Its automation mechanized operation degree.The withdrawal that lifting arm is realized in operation is fallen after rise by a key, can prevent machine hand from being made because not observing position
At movement interference and safety accident, keep more convenient operation intelligent.And travel position is recovered to by a key operation lifting appliance,
It can make operation more hommization, intelligence while ensureing safe.
The recycling and control method of a specific embodiment of auxiliary lifting equipment provided by the utility model is set forth below, when need
When withdrawing auxiliary lifting equipment from working condition to travel position, presses lifting appliance and withdraw button or handle, lifting appliance
Automatic sequence carries out rotating back to zero-bit (revolution resets), retraction and the operation of pitching downwards, returns to transporting position, concrete methods of realizing
It is as follows：
As shown in fig. 6, when recycling key or handle is pressed, first determine whether two thirds have signal close to switch 61,
If not having signal close to switch 61 for detecting the third turned in revoliving arm 1, for detecting, the third turned outside revoliving arm 1 is close to be opened
Closing 61 has signal, then controller first sends out instruction and makes to go to two thirds in revoliving arm 1 has signal, judgement to revolve close to switch 61
Rotate back into zero-bit (revolution resets)；If conversely, having signal close to switch 61 for detecting the third turned in revoliving arm 1, for examining
The third turned outside survey time pivoted arm 1 does not have signal close to switch 61, then controller, which first sends out instruction, makes revoliving arm 1 go to two the outside
Three have signal, judgement to be rotated back to zero-bit close to switch 61 (revolution resets)；Then judge whether second have close to switch 51
Signal, if not having, controller, which sends out instruction, makes telescopic oil cylinder 9 retract, until second detects the second detection plate close to switch 51
52, there is a signal, judgement telescopic arm 3 is withdrawn completely, and last controller sends out instruction, and so that pitching oil cylinder 7 is gradually extend out to fully extended
State, principal arm 2 rotate down folding relative to revoliving arm 1 and close at revoliving arm 1, reach transporting position.
It is at low cost close to switch in above-mentioned each embodiment, it is easy for installation, it occupies little space, close to the function of switch
It can be realized with limit switch.
