Travel switch is sent out, until the idler wheel of travel switch is contacted with first end face 22 when horizontal support legs and vertical supporting leg are retracted in place,
The degree that first end face 22 drives the idler wheel of travel switch to retract at this time can trigger travel switch.Top surface 21 is obliquely installed can
Facilitate the idler wheel of travel switch gradually to move to along top surface 21 to contact with first end face 22, improves the stability of triggering and steady
Property.
As another embodiment, detection piece 1 includes close to switch.
It is fixed on horizontal support legs case 3 close to switch, locating piece 2 is fixed on vertical movable supporting legs 6.In horizontal support legs and
When vertical supporting leg retracts, locating piece 2 moves closer to approach switch, and locating piece 2 is not at the induction region close to switch at this time
Interior, locating piece 2 cannot be triggered close to switch, until horizontal support legs and vertical supporting leg are in when retracting state in place, be approached
The induction zone and locating piece 2 of switch are correspondingly arranged with through-hole 61 respectively, and can extend into through-hole 61 close to the induction zone of switch,
And it is spaced relatively small distance with locating piece 2, locating piece 2 enters proximal in the induction region of switch at this time, and locating piece 2 can
The close switch of triggering.
In the case where horizontal support legs and vertical supporting leg retract state in place, if horizontal anomalous movement supporting leg 4 stretches out horizontal support legs case 3,
As horizontal anomalous movement supporting leg 4 is far from close to switch movement, locating piece 2 is detached from close to switch locating piece 2 on vertical movable supporting legs 6
Induction region, locating piece 2 can not trigger travel switch, and control system can not receive the triggering information of travel switch, to sentence
Disconnected horizontal support legs and vertical supporting leg are not in retraction state in place.
In the case where horizontal support legs and vertical supporting leg retract state in place, if vertical movable supporting legs 6 stretch out vertical outrigger box 5,
Locating piece 2 on vertical movable supporting legs 6 is moved down with vertical movable supporting legs 6, and locating piece 2 is detached from the induction region close to switch,
Locating piece 2 can not trigger travel switch, and control system can not receive the triggering information of travel switch, thus determined level supporting leg and
Vertical supporting leg is not in retraction state in place.
When horizontal anomalous movement supporting leg 4 and vertical movable supporting legs 6 are all in the state of stretching, locating piece 2 is detached from close to switch
Induction region, locating piece 2 can not trigger travel switch, and control system can not receive the triggering information of travel switch, to judge
Horizontal support legs and vertical supporting leg are not in retraction state in place.
Further, there is gap between locating piece 2 and the inner wall of vertical outrigger box 5.It can be in vertical 6 band of movable supporting legs
When dynamic locating piece 2 is moved relative to vertical outrigger box 5, prevents from rubbing between locating piece 2 and vertical outrigger box 5, improve and use the longevity
