Slewing mechanism for low-consumption crane tower

Abstract

The invention discloses a slewing mechanism for a low-consumption crane tower. The slewing mechanism comprises a first column body, through hole blocks are fixedly connected to the left side and the right side of the outer wall of the first column body correspondingly, a cylinder body is fixedly connected to the bottom of a through hole plate, clamping grooves are formed in the left side and the right side of the outer wall of the cylinder body correspondingly, sliding grooves are formed in the left side and the right side of the inner wall of the cylinder body correspondingly, sliding blocksare connected to the inner walls of the sliding grooves in a sliding mode, second columns are fixedly connected to the outer walls of the two sliding blocks, the outer walls of the second columns arein clearance fit with the inner wall of the cylinder body, a rotary disc is fixedly connected to the cylinder body and the bottoms of the two sliding blocks, and the rotary disc is rotationally connected with a transverse plate through a bearing. According to the slewing mechanism for the low-consumption crane tower, through sliding connection of the sliding grooves and the sliding blocks, the through hole plate and the transverse plate are subjected to rapid butt joint, rapid positioning connection or rapid disassembly is achieved, a clamping rod and a clamping groove are connected in a clamped mode, after the cylinder body and the rotary disc are subjected to positioning connection, rapid fixing is conducted, and the fitting connection stability of the cylinder body and the rotary disc is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical technology, in particular to a slewing mechanism for a low-consumption pendant tower. Background technique [0002] Pendant tower refers to the tower frame of the crane. It usually refers to the general term of the transfer tower used in construction engineering. Generally, the base cannot be moved, and there are also pendants that move according to the track. [0003] For example, the patent number is: 201710120628.9, a low-consumption pendant rotating structure, including a bottom mounting plate and a top mounting plate, the bottom of the side of the bottom mounting plate is provided with a bottom connecting plate, although it can realize the rotation mechanism of the pendant. Low consumption, but there is a problem that when the existing pendant tower is disassembled and maintained by the slewing mechanism, it is time-consuming and laborious, and it is inconvenient to quickly disassemble and...
