In order to achieve the purpose, the utility model provides the following technical scheme:
a gantry supporting leg for monorail crane equipment comprises a connecting seat, an outer sleeve, an inner sleeve, a supporting outer sleeve and a supporting inner sleeve which are sequentially connected; a turnover oil cylinder is arranged between the inner sleeve and the supporting outer sleeve and is used for controlling the supporting outer sleeve to turn over relative to the inner sleeve; the supporting oil cylinders are arranged in the supporting outer sleeve and the supporting inner sleeve and are used for controlling the supporting inner sleeve to stretch in the supporting outer sleeve; and the connecting seats of the gantry supporting legs are respectively connected with the left gantry supporting leg hinging seat, the right gantry supporting leg hinging seat and the rotary oil cylinder seat on the main frame body.
Furthermore, the head end and the tail end of the outer sleeve and the inner sleeve are connected with telescopic oil cylinders, and the telescopic oil cylinders are used for controlling the inner sleeve to stretch out and draw back in the outer sleeve.
Compared with the prior art, the utility model has the following beneficial technical effects:
1. the gantry supporting legs are arranged inside the main frame body, so that the gantry supporting legs are convenient to open and retract, the structure is compact, and no extra space is occupied; the supporting oil cylinder is arranged inside the supporting inner arm, so that the structure is compact, and the oil cylinder can be well protected;
2. by controlling the extension and retraction of the rotary oil cylinder, the turnover oil cylinder and the telescopic oil cylinder, the angle of the supporting leg can be conveniently adjusted according to the size of the roadway, and the actual supporting requirement is met.
