Specific embodiment
Illustrate that the utility model, the following example are merely to illustrate the skill of the utility model below in conjunction with specific embodiment
Art scheme, does not limit the protection scope of the utility model.
Embodiment:
It as illustrated in fig. 1 and 2, is a kind of micro lifter equipped with high pressure near-electricity alarming safety installation, the small-sized derrick car
Crawler body 1 use rubber belt track, drive crawler travels by two groups of hydraulic motors, crawler body 1 is fixed on 3 lower section of vehicle frame,
Four collapsible supporting legs 7 are hingedly connected on vehicle frame 3 simultaneously.Support oil cylinder 8 is hingedly connected on vehicle frame 3 and folding landing leg 7.Work
When making, need to open folding landing leg 7, work finishes the withdrawal of folding landing leg 7.Reversing frame 4 is connected to vehicle frame 3 by pivoting support
On, crane arm 5 and amplitude oil cylinder 6 are hingedly connected to above reversing frame 4.Winch 13 is fixedly connected on reversing frame 4, on winch 13
It is wound with wirerope 14, steel cord ends are connected with hook gear 15.
Hydraulic device is made of gear pump 91, oil pipe 92, multi-way valve 93.Pass through shaft coupling between engine 2 and gear pump 91
Device connection, gear pump 91 are connect with multi-way valve 93 by oil pipe 92, and multi-way valve 93 and engine 2 are fixedly mounted on vehicle frame 3.It is more
Road valve 93 can control walking, supporting leg, hoist of derrick car etc. to act.For the rotation fuel feeding for solving the problems, such as crane arm 5, reversing frame 4
Lower section is provided with center-rotary joint.
It is electrical that the derrick car electric control gear needs to control the starting of engine 2, limiter of moment 102, walking switching valve 103 etc.
