Problems solved by technology

In order to improve the anti-overturning ability of the equipment, such as figure 1 As shown, some manufacturers have installed a rotating outrigger 2' on the outrigger arm 1' to increase the span of the outrigger; however, this rotating outrigger 2' can only rotate within a certain range, and the rotating outrigger 2' ' position cannot follow the extension direction of the jib for corresponding rotation movement. In addition, a new rotating outrigger 2' is added to each outrigger arm, which affects the overall strength of the outrigger arm 1' and also affects the quality of the vehicle. The increase is too large, and the cost input is too high

Abstract

The invention discloses a supporting leg assembly and mechanical equipment. The supporting leg assembly comprises a first supporting leg, a rotating arm and a second supporting leg. The first supporting leg comprises a first fixing leg and a first telescopic leg telescopically arranged on the first fixing leg; the rotating arm is rotatably arranged on the first fixing leg; and the second supporting leg comprises a second fixing leg and a second telescopic leg telescopically arranged on the second fixing leg, the second leg is fixed to the rotating arm, and the second supporting leg can rotatearound the first supporting leg through the rotating arm. According to the technical scheme, the second supporting leg can rotate all-directionally by 360 degrees, and the anti-tipping capacity, the working stability and the adaptability of special working conditions during working of the equipment are greatly improved.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a leg assembly and a mechanical device. Background technique [0002] Before the lifting engineering equipment works, the four outriggers stretch out to support the ground to form a square or trapezoid, which is used to bear the weight of the whole vehicle and the boom system (including boom, connecting rod, oil cylinder, delivery pipe and water, etc.) The resulting bending moment prevents overturning. In order to improve the anti-overturning ability of the equipment, such as figure 1 As shown, some manufacturers have installed a rotating outrigger 2' on the outrigger arm 1' to increase the span of the outrigger; however, this rotating outrigger 2' can only rotate within a certain range, and the rotating outrigger 2' ' position cannot follow the extension direction of the jib for corresponding rotation movement. In addition, a new rotating outrigger 2' is added to...
