22 cylinder body is mounted on bracket base 11, and piston rod is mounted on 21 lower end surface of top beam, one end and top of two caving shields 23
Beam 21 is hinged, and the other end is hinged with one end of two front rods 24 respectively, and the other end of two front rods 24 is hinged on bracket bottom
On seat 11, two balance jacks 26 are respectively hinged between top beam 21 and two caving shields 23, one end of two back links 25
It is respectively hinged on two caving shields 23, the other end is hinged on bracket base 11.
Further, the bracket upright post 22 is double-telescopic upright post, and lower end is mounted on bracket base by needling and pin shaft
On 11, upper end is mounted on top beam 21 by bolumn cap and pin shaft.
Preferably, described two advancing jacks 13, two carried bottom jacks, 14, two steerings compress jack 32 and two
The anti-inclination structure 4 of group is to be centrosymmetrically arranged.
Preferably, two tracks 12 in the step by step structure 1 are connect with two guide rails of equipment train respectively.
When the present invention needs mobile: the piston rod of carried bottom jack 14 stretches out in step by step structure 1, and idler wheel 15 is pressed in track
On 12, on the ground by the pressure of track 12, and lifting 2 front end of support structure is made to lift certain height, subsequent advancing jack
13 piston rod stretches out, so that lifting support structure 2 moves forward certain distance, the idler wheel 15 on 14 piston rod of carried bottom jack
Corresponding distance is rolled on the track 12, and sliding friction is become into rolling friction, reduces frictional force；Then, carried bottom jack
14 piston rod retracts, and idler wheel 15 leaves track 12, and lifting support structure 2 is fallen after rise, and the bottom of bracket base 11 contacts ground, this
When, the weight of bracket base 11 and lifting support structure 2 is largely undertaken by ground, and 13 piston rod of advancing jack retracts, band
The forward movement of dynamic rail road 12 respective distance is so far a mobile step-length of the present invention, repeats above-mentioned movement, and the present invention realizes certainly
It moves, drives equipment train mobile by traction jack 5.
When the tractional force deficiency of advancing jack 13 in the present invention, traction jack 5 is started to work, and it is very heavy to retract traction
The piston rod on top 5 can drive equipment train mobile, and then the piston rod of advancing jack 13 stretches out, while drawing jack 5
Traction 5 rodless cavity of jack is released, compensates the insufficient thrust of advancing jack 13 by rod chamber oil inlet, pushes lifting support knot
Structure 2 moves forward, then the piston rod of retract at the same time advancing jack 13 and traction jack 5, drives equipment train mobile, so
It can guarantee present invention work a period of time, look for suitable time maintenance advancing jack 13 again later.
When equipment train can not be moved during from shifting by improper resistance, 22 piston rod of bracket upright post is stretched
Out, the top beam 21 in the present invention is propped up and holds out against back, generate biggish setting load, retract the piston of traction jack 5
Bar pulls equipment train to overcome improper resistance mobile.
It when the present invention needs to turn to, is mounted in the steering structure 3 of 11 rear and front end of bracket base, it is very heavy to turn to compression
The piston rod on top 32 stretches out, and makes to turn to the compression of supporting box 31 on the ground, and bracket base 11 is raised certain altitude, then
Former and later two piston rods for turning to jack 33 stretch out simultaneously, push the present invention to rotate certain angle, while turning to compression thousand
The sliding block 35 of 32 piston rod ends of jin top slides certain distance in sliding slot 34, then turns to the piston rod contracting for compressing jack 32
It returns, 31 band of supporting box will be turned to from the ground, the piston rod for finally turning to jack 33 retracts, and it is multiple that drive turns to supporting box 31
Position.
When the present invention rolls, the ipsilateral anti-piston rod for rolling jack 42 stretches out, and anti-inclination supporting leg 41 is released,
Stable triangular structure is formed, inclination of the present invention is prevented, when not needing anti-inclination, the anti-piston rod contracting for rolling jack 42
It returns, the anti-supporting leg 41 that rolls is withdrawn on the side for abutting against bracket base, saves space occupied of the invention.
The embodiment of the present invention is explained in detail above in conjunction with attached drawing, but the present invention is not limited to above-mentioned implementations
Example, within the knowledge of a person skilled in the art, can also make without departing from the purpose of the present invention
Various change out.
