Referring to fig. 1 to 4, regarding the first embodiment of the connection manner between the overturning hydraulic cylinder 123 and the stabilizing hydraulic cylinder 124 and the first overturning shaft 121 and the second overturning shaft 122, the overturning telescopic mechanism 12 further includes a first fixing lug 125 disposed on the first overturning shaft 121 and a second fixing lug 126 disposed on the second overturning shaft 122, the first end of the overturning hydraulic cylinder 123 and the first end of the stabilizing hydraulic cylinder 124 are both rotationally connected with the first fixing lug 125, and the second end of the overturning hydraulic cylinder 123 and the second end of the stabilizing hydraulic cylinder 124 are both rotationally connected with the second fixing lug 126. Like this, through first fixed ear 125 and second fixed ear 126, can guarantee that upset pneumatic cylinder 123 is connected more stably with the rotation of first upset axle 121 and second upset axle 122 respectively, and in the same way, can guarantee that stable pneumatic cylinder 124 is connected more stably with the rotation of first upset axle 121 and second upset axle 122 respectively.
Detailedly, the first ends of the first fixing lugs 125 are both rotationally connected with the first turning shaft 121 and the first end of the stabilizing hydraulic cylinder 124, the second ends of the first fixing lugs 125 are rotationally connected with the first end of the turning hydraulic cylinder 123, the first ends of the second fixing lugs 126 are both rotationally connected with the second turning shaft 122 and the second end of the stabilizing hydraulic cylinder 124, and the second ends of the second fixing lugs 126 are rotationally connected with the second end of the turning hydraulic cylinder 123.

Thus, the first end of the stabilizing cylinder 124 is rotatably connected to the first fixing block 127, and the second end of the stabilizing cylinder 124 is rotatably connected to the second fixing block 128, and since the positions of the first fixing block 127 and the second fixing block 128 are unchanged, it is advantageous for the stabilizing cylinder 124 to stably maintain the relative position between the first tilting shaft 121 and the second tilting shaft 122. The first end of the overturning hydraulic cylinder 123 is rotatably connected with the second end of the first fixed lug 125, the second end of the overturning hydraulic cylinder 123 is rotatably connected with the second end of the second fixed lug 126, and the free ends can rotate relative to the fixed ends firstly because the second end of the first fixed lug 125 and the second end of the second fixed lug 126 are both free ends, so that the overturning hydraulic cylinder 123 can adapt to the relative position change between the first overturning shaft 121 and the second overturning shaft 122 when telescoping.

Compared with the single cylinder type, the two hydraulic cylinders form a support for the first lifting arm 112 together, so that the maximum hydraulic acting force value of the single hydraulic cylinder can be reduced, and the system pressure of the whole hydraulic system can be reduced. Of course, in the present embodiment, the number of hydraulic cylinders is not limited to two in the present embodiment, and three or more hydraulic cylinders may be provided with a sufficient installation space.

when the lifting device 10 is adopted in the mobile maintenance station, when an accident vehicle needs to be maintained, a worker carries the mobile maintenance station to the place where the accident vehicle is located, then the horizontal driving mechanism 14 is controlled by the operation controller to move the lifting driving mechanism 11 out of the mobile mounting platform (the mobile mounting platform is actually a carriage of the mobile vehicle), then the lowering driving mechanism 13 is controlled by the operation controller to lower the lifting driving mechanism 11 onto the ground, then the two groups of lifting driving mechanisms 11 are required to be respectively stretched, and meanwhile, the lifting driving mechanisms 11 are required to be stretched in the vertical direction, so that the bearing point of the automobile is placed on the lifting top plate 114, and the automobile is lifted by the lifting top plate 114. Therefore, by adopting the lifting driving mechanism 11, the accident vehicle can be lifted automatically and quickly, convenience is brought to maintenance and repair of the accident vehicle by a worker technician, and when two groups of lifting driving mechanisms 11 are respectively stretched, the two groups of lifting driving mechanisms adopt the rotating hydraulic cylinder and the stabilizing hydraulic cylinder 124, the second rotating shaft 122 is driven to rotate in a turnover manner relative to the first rotating shaft 121 by the larger hydraulic acting force provided by the rotating hydraulic cylinder 123, the stabilizing hydraulic cylinder 124 provides smaller hydraulic acting force to assist the second rotating shaft 122 to rotate in a turnover manner relative to the first rotating shaft 121, the stabilizing hydraulic cylinder 124 plays a role of stabilizing the relative turnover motion between the second rotating shaft 122 and the first rotating shaft 121, and enables the second rotating shaft 122 and the first rotating shaft 121 to keep a better relative position relation, so that when the two lifting driving mechanisms 11 are stretched and placed on the ground, one lifting driving mechanism 11 is not crashed by the ground due to overlarge unloading force of the rotating hydraulic cylinder 123, and the stabilizing hydraulic cylinder 124 can play a role of assisting the stabilizing supporting mechanism when the unloading force of the rotating hydraulic cylinder 123 is overlarge, so that the lifting driving mechanism 11 can be prevented from being damaged by the fact that the lifting driving mechanism 11 is in a strong motion or the potential safety hazard of a lifting mechanism is caused by the fact that the lifting driving mechanism is high, and the lifting driving mechanism is stable, and the potential safety hazard is avoided, and the lifting mechanism is caused to be expanded and damaged at the ground.
Preferably, the mobile mounting platform of the present embodiment is an automobile with a rear compartment, or a van, and the lifting device 10 is mounted in the compartment.
In this embodiment, the controller may be a central processing unit which is mature in the prior art, or may be a PLC device which is commonly used in industry.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
