Abstract

The invention provides a supporting leg applying a limit switch. The supporting leg comprises a supporting leg body, an oil cylinder ejector rod, an oil cylinder barrel, oil cylinder end plates, chassis connecting seats and a limit component, wherein the oil cylinder ejector rod is connected with the supporting leg body; the chassis connecting seats are fixedly connected with a mounting plate; a grounding plate is arranged at the lower part of the supporting leg body; the oil cylinder end plates are integrally arranged at the lower part of the oil cylinder barrel; a plurality of through holesare symmetrically formed in the edge of each oil cylinder end plate; the edges of the oil cylinder end plates are fixedly connected with the chassis connecting seats through bolts; the chassis connecting seats are symmetrically fixed to four corners of an aerial work platform device; the limit component comprises two limit switches, a contact shaft and the mounting plate; the upper positions and the lower positions of the two limit switches are arranged on the inner side of the mounting plate; the lower part of the mounting plate is fixed to the oil cylinder end plates through the bolts; an oil cylinder assists power to the supporting leg applying the limit switch, which is only pressed manually in the prior art, and since the moving stroke is limited by a travel switch, the supporting function is realized to the maximum limit on an actual unsmooth pavement, hydraulic control can easily realize automatic adjustment of the height of the supporting leg, and high safety and high efficiency are achieved.

Description

technical field [0001] The invention relates to the technical fields of high-altitude operation and transportation, and more particularly, relates to a support leg of a high-altitude operation platform using a limit switch. Background technique [0002] During the use of the aerial work platform, if the road surface is uneven or on a slope, in order to improve the anti-overturning ability of the aerial work platform, it is necessary to use outriggers and adjust the elongation of the outriggers to the maximum to meet different needs. The height difference brings imbalance to the equipment, and at the same time, it has sufficient supporting force; it provides strong structural support to overcome the complex and changeable road environment, and is convenient for construction operations. [0003] Prior art: CN 106927406 A discloses a leveling leg of an aerial work platform, including a connecting frame for connecting the chassis and a leveling oil cylinder installed on the conn...
