The invention discloses an automobile crane and a supporting leg operating device thereof. An operating rod of the disclosed supporting leg operating device is used for operating a supporting leg to extend or retract; the operating rod comprises a main body part, a transmission part, a connecting part for connecting the main body part and the transmission part, and a fixing component for fixing the relative position of the main body part and the connecting part; and the main body part is screwed with the connecting part, and the transmission part is fixedly connected with the connecting part.The length of the operating rod is adjusted by the screwing degree of the main body part and the connecting part, and the operating rod is firm and reliable by fixing the relative position between the main body part and the connecting part through the fixing component. Therefore, left and right wobble of the operating rod during use can be avoided, control of extension and retraction of the supporting leg through an operator is more convenient and labor-saving, the operation is smoother, and the comfort degree when the supporting leg is operated is remarkably increased; and the length of the operating rod can be adjusted, so that the length of the operating rod in the supporting leg operating device is kept consistent, and the attractiveness of the supporting leg operating device is improved.
Description
technical field [0001] The invention relates to the field of cranes, in particular to an outrigger control device for a truck crane. In addition, the present invention also relates to a truck crane comprising the above-mentioned outrigger handling device. Background technique [0002] The truck crane is a kind of heavy equipment used to lift heavy objects, and the outriggers are its important components. When the crane must extend the outriggers before carrying out lifting operations, the telescopic action of the outriggers is controlled by the hydraulic system of the outriggers, and the control element in the hydraulic system of the outriggers is a hydraulic multi-way valve. The reversing of the spool controls the on-off of the hydraulic oil circuit of the outrigger to control the telescopic movement of the outrigger. The reversing of the valve core is realized by manually pulling the joystick connected to the valve core, that is, the operator controls the outrigger teles...
