Abstract
The invention relates to a hydraulic support device, in particular to a hydraulic support leg. The hydraulic support leg comprises a hydraulic cylinder and a bracket, wherein one end of the hydraulic cylinder is connected to the bracket. The hydraulic support leg also comprises a rotating support leg and a rolling wheel, wherein one end of the rotating support leg is connected to the bracket, and the other end of the rotating support leg is connected with the rolling wheel. The hydraulic support leg provided by the invention can reduce the friction with the road surface and simultaneously reduces the lateral force.
Description
Technical field
The present invention relates to a kind of hydraulic support device, specifically is a kind of hydraulic ram.
Background technology
Vertical hydraulic supporting leg during existing highway is cared the car, referring to Fig. 1, the upper end of vertical hydraulic supporting leg 1 is fixed on the support 2, two vertical hydraulic supporting legs of general use, be fixed on the support left and right sides, run into road surfaces such as upward slope, descending, fluctuating, this vertical hydraulic supporting leg can bear more side force when stretching out carrying, damages hydraulic ram easily.
Summary of the invention
The objective of the invention is to overcome the deficiency that hydraulic ram of the prior art is subjected to the side force infringement easily, a kind of hydraulic ram of avoiding the side force infringement is provided.
Technical scheme of the present invention is: hydraulic ram comprises hydraulic ram, support, hydraulic pressure
Oil cylinder one end is connected on the support, also comprises swing leg, roller, and supporting leg one end is connected on the support, and the other end links to each other with roller.
Further, swing leg and hydraulic ram are hinged.
Beneficial effect of the present invention: the present invention can reduce and the ground-surface friction, also reduces side force simultaneously.
Description of drawings
Fig. 1 is traditional vertical hydraulic leg structure figure;
Fig. 2 is a hydraulic ram constructional drawing of the present invention.
The specific embodiment
Referring to Fig. 2, hydraulic ram 5 one ends and support 2 are hinged, the other end and swing leg 6 are hinged, swing leg 6 one ends and support 2 are hinged, the other end and roller 3 are hinged, and swing leg 6 rotates around S. A. 7 under the drive of hydraulic ram 5, and roller lands the back around the axis of rolling 4 rotations, reduce and the ground-surface friction, also reduce side force simultaneously.
Claims (2)
