Abstract

The invention provides a crane and a sub arm installing device thereof. The device comprises a linear driving mechanism and a connecting rod, wherein the linear driving mechanism comprises a fixed component and a movable component, the movable component is fixedly arranged on the side surface of a main arm and does linear reciprocating movement relative to the fixed component, the reciprocating movement direction is parallel to the side surface of the main arm, the first end of the connecting rod is hinged onto a hinging seat of a sub arm, the movable component pushes and pulls the second end of the connecting rod, and further, the first end of the connecting rod drives the sub arm to swing around the main arm. The crane and the sub arm installing device can realize the high-automation installation and folding of the sub arm and have the advantages that the operation efficiency is high, the alignment is precise, the applicability is high, the swinging speed is controllable, and the like.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a crane jib installation device and a crane including the jib installation device. Background technique [0002] The jib system of current cranes (especially truck cranes) often includes a main jib (hereinafter referred to as the main jib) and an auxiliary jib (hereinafter referred to as the jib). The setting of the auxiliary arm can compensate the operating height of the main arm and expand the operating range of the main arm. [0003] The assembly connection of the auxiliary arm and the main arm is usually formed by hinged connection of four forks at the tail of the auxiliary arm and four joint holes at the head of the main arm. When the jib is not working, the jib is folded on the side or below the main arm; when the jib is required to work, the jib is deployed and installed on the boom head of the main arm. [0004] When installing the auxiliary arm, it is usually first...
