Foldable supporting leg and engineering car with same

Abstract

The invention discloses a foldable supporting leg and an engineering car with the same, and relates to the technical field of supporting devices. The foldable supporting leg comprises a car body, a mounting seat, a sliding sleeve and a hydraulic cylinder, the mounting seat is mounted on the car body, one end of the sliding sleeve is slidably mounted in the mounting seat in a reciprocating manner,the sliding direction of the sliding sleeve is parallel to axes of wheels on the car body, an opening is formed in the lower surface of the sliding sleeve, hiding space is formed in the sliding sleeveby the aid of the opening, the hydraulic cylinder is hinged into the hiding space, a hinging position approaches to the other end of the sliding sleeve, the swinging direction of the hydraulic cylinder and the sliding direction of the sliding sleeve are in the same plane, and a supporting seat is mounted at the end of the telescopic pole of the hydraulic cylinder. The foldable supporting leg hasthe advantage that the foldable supporting leg is simple in structure, foldable and convenient to use.

Description

technical field [0001] The invention relates to the technical field of support equipment, in particular to a foldable outrigger and an engineering vehicle with the foldable outrigger. Background technique [0002] A considerable number of engineering vehicles adopt the type of central shaft, and lifting outriggers need to be installed at the traction frame. When the main suspension is separated, the outriggers must be in a supporting state to ensure the balance of the engineering vehicle. When the main suspension is connected and walking, the outriggers must be Stow a certain height to ensure the passability of the whole vehicle; the outriggers of engineering vehicles are generally composed of fixed outriggers, movable outriggers, outrigger cylinders, etc.; The vertical oil cylinders protrude out of the supporting ground to ensure that the vehicle will not overturn and the chassis parts will not be damaged under various operating conditions. However, the vertical oil cylinde...

[0002] A considerable number of engineering vehicles adopt the type of central shaft, and lifting outriggers need to be installed at the traction frame. When the main suspension is separated, the outriggers must be in a supporting state to ensure the balance of the engineering vehicle. When the main suspension is connected and walking, the outriggers must be Stow a certain height to ensure the passability of the whole vehicle; the outriggers of engineering vehicles are generally composed of fixed outriggers, movable outriggers, outrigger cylinders, etc.; The vertical oil cylinders protrude out of the supporting ground to ensure that the vehicle will not overturn and the chassis parts will not be damaged under various operating conditions. However, the vertical oil cylinders of the existing engineering vehicle legs are fixed and vertically installed on the movable legs. side, the ground clearance after installation is small, which affects the passability of the vehicle, the minimum ground clearance and departure angle of the passability of the vehicle, and limits the structural design of some engineering vehicles
