Two-degree-of-freedom translational type crane auxiliary arm mounting device

Abstract

A two-degree-of-freedom translational type crane auxiliary arm mounting device comprises a driving mechanism, a switching mechanism and a butting mechanism, wherein the driving mechanism comprises a roller group and a cable wire hauling mechanism; the roller group is fixed on a side surface of an auxiliary arm, and can roll along a sliding chute fixed on the side of a main arm; the cable wire hauling mechanism is used for achieving parallel translation of the auxiliary arm on one side of the main arm through the cable wire hauling and roller combination; the switching mounting mechanism (switching mechanism) comprises a connecting rod, a motor, a slide track and a pulley; the aligned positioning and mounting of the mounting part at the tail part of the auxiliary arm and the mounting part at the top of the main arm can be achieved through motion driven by the power provided by the motor. According two-degree-of-freedom translational type crane auxiliary arm mounting device, the process of auxiliary arm mounting is simplified, the auxiliary arm unfolding and folding are avoided, and the operation area is reduced. Therefore, requirements to operating environment are lowered.

Description

technical field [0001] The invention relates to the field of cranes, in particular to a two-degree-of-freedom translational crane jib installation device. Background technique [0002] At present, the jib system of the crane includes the main arm and the auxiliary arm. 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, usually first align the proximal fork with the proximal hole, insert the proximal pin, and then manually pull the auxiliary arm to swing along the pro...
