Detailed Description

The following description will further describe embodiments of the present invention with reference to the accompanying drawings.

In the figures 1-5, the device comprises a forward extending support leg 1, a support leg seat 1-1, a rectangular steel pipe 1-1-1, a rectangular pipe support rib 1-1-2, a front support leg oil cylinder 1-2, a swing leg 1-3, a front ground grabbing support 1-4, a frame 2, a pattern steel plate 3, a rear support leg 4, a rear support leg oil cylinder 4-1, a rear ground grabbing support seat 4-2 and the like.

As shown in fig. 1-2, the utility model relates to a rig platform with advance support leveling arm, including frame 2, 2 front end installations of frame are foreword landing leg 1, and 2 rear end installations of frame are back landing leg 4, in order to increase the security of frame 2, prevent that the walking of during operation operating personnel from taking place the phenomenon of skidding, lay decorative pattern steel sheet 3 in frame 2.

As shown in fig. 3-4, the forward extending leg 1 includes a leg base 1-1, one end of the leg base 1-1 is welded on the frame 2, and the connecting strength is increased by the inner vertical plate and the outer reinforcement, the middle part of the leg base 1-1 is hinged with the cylinder body pin hole of the front leg oil cylinder 1-2 by the pin shaft symmetrically arranged, the piston rod end of the front leg oil cylinder 1-2 is hinged with the tail end of the swing leg 1-3, as shown in fig. 5, the swing leg 1-3 is V-shaped, the middle part of the swing leg 1-3 is hinged with the front end of the leg base 1-1, and the other end of the swing leg 1-3 is hinged with the upper part of the front ground-catching support 1.

Further, the rack comprises rectangular steel pipes 1-1-1, the rectangular steel pipes 1-1-1 are welded into a frame shape, and rectangular pipe supporting ribs 1-1-2 are welded between the connected rectangular steel pipes 1-1-1 to improve the strength of the leg support base 1-1.
