Abstract

The invention discloses a universal-angle lorry-mounted crane telescopic boom, and belongs to the field of lorry-mounted hoisting. The universal-angle lorry-mounted crane telescopic boom comprises a main boom main body and a telescopic assembly, the telescopic assembly is mounted on the main boom main body, the telescopic assembly is suitable for moving in the extension direction along the axis of the main boom main body, a hand pulling arm is mounted on the side, back to the main boom main body, of the telescopic assembly, the hand pulling arm is detachably connected with the telescopic assembly, a rotating arm is installed on the side, back to the telescopic assembly, of the hand pulling arm, a center hole and circumferential holes are formed in the rotating arm, a positioning hole is formed in the telescopic assembly, and the center hole and the circumferential holes are suitable for installation of positioning pieces and penetrate through the positioning hole to be locked, multiple sets of circumferential holes are formed; and the multiple sets of circumferential holes are suitable for being distributed in the circumferential direction of the center of the center hole and are suitable for being detachably connected with the positioning piece and rotationally adjusting the rotating arm. The technical problems that the rotating arm cannot be adjusted at multiple angles to adapt to different working environments, and the angle needs to be completely detached and adjusted can be solved.

Description

technical field [0001] The invention belongs to the field of truck-mounted cranes, in particular to a telescopic arm of a truck-mounted crane with a universal angle. Background technique [0002] In the design of the telescopic arm of the folding arm of the traditional truck-mounted crane, the telescopic arm is extended and shortened through the telescopic oil cylinder. The disadvantage of this design is that when working in a narrow space, the telescopic oil cylinder interferes with the upper object or the hoisting object interferes with the telescopic arm body when the elevation angle of the telescopic arm is too large. Thus affecting product quality and market competitiveness. [0003] The manual variable angle of the folding arm of the truck-mounted crane in the prior art is basically a fixed angle, which can only be changed in two directions, and when changing the angle, the handle must be pulled out and turned 180 degrees. The changing angle is limited and cannot be a...
