Problems solved by technology

However, it is large in size and complex in structure, and is only suitable for installation at the head or tail of the outer outrigger, and is not used for wider outriggers.
In addition, when the inner leg does not need to be leveled, the clearance adjustment of the above-mentioned bearing support device is cumbersome.

Abstract

The invention discloses a landing-lag gap adjusting device, comprising a sliding sleeve fixedly connected on an outer landing lag, a roller frame arranged in the sliding sleeve in a up-down movement manner, and an adjusting bolt connected to the sliding sleeve in a screw manner, wherein, the roller frame is installed with a roller which supports an inner landing lag along the width direction of the inner landing lag; and the adjusting bolt is used for adjusting the position of the roller frame in the sliding sleeve. The landing-lag gap adjusting device of the invention has simple structure, compact volume, simple adjustment and installation, no restriction on installation position and on the width of the landing lag, and can realize leveling of the inner landing leg.

Description

technical field [0001] The invention relates to a leg gap adjustment device used on vehicles such as wheeled cranes. Background technique [0002] There must be a small gap between the fixed outriggers and the movable outriggers, and between the movable outriggers and the movable outriggers of vehicles such as wheeled cranes, otherwise, the movable outriggers will sag obviously, and the optimal position and movement of the movable outriggers cannot be guaranteed. state. [0003] On the outriggers of some wheeled cranes and other vehicles, the outer outriggers (such as fixed outriggers) are provided with adjustment bolts, and the inner outriggers (such as movable outriggers) are supported on the top surface of the adjustment bolts. The telescopic movement of the inner outriggers There is greater frictional resistance and wear, and the gap adjustment between the inner and outer legs is more frequent. In addition, the cylinder pressure and wire rope diameter and other compone...
