Description

Leg board back slope mouth frock

Technical Field

The utility model relates to the technical field of tower crane component structures, in particular to a leg plate slope opening chamfering tool.

Background

The support leg is one of the main components of the automobile crane, and is used for increasing the support base of the crane, reducing the tire load and improving the anti-overturning stability of the whole automobile, thereby improving the lifting capacity. The support leg is a supporting device arranged on the underframe of the crane and comprises a fixed part and a movable extending part. The crane is generally provided with four supporting legs which are respectively arranged at the front, the rear, the left and the right sides, and can simultaneously act and independently stretch. Because the work site is basically inclined and uneven and the ground is soft, sleepers are needed under the legs, and the heights of the legs are adjusted by looking at levels near the legs so that the leg plates of the legs are on the same horizontal plane.

The supporting legs are firm and reliable in design requirement and can be freely folded and unfolded. When the lifting is in operation, the supporting legs extend outwards to the ground, and the span of the bearing surface is increased. When the automobile runs, the supporting legs are retracted, the overall dimension is reduced, and the running passing performance is improved.

The leg plates need to be milled and welded with grooves in most of the existing production processes, but in the prior art, only one leg plate can be milled at a time, so that the production efficiency is low, and the labor cost is high. Therefore, the existing chamfering tool needs to be improved, so that a plurality of supporting leg plates can be milled at one time, the operation is safe and stable, and the production efficiency is improved, so that the production cost is reduced.
