Abstract

The invention discloses a tower crane device and an operating method thereof. The tower crane device comprises a main tower body (21), a sleeve frame (22) arranged at the top of the main tower body (21) in a sleeve manner, a gear disk (24) fixedly mounted at the top end of the sleeve frame (22), a rotating frame (27) rotationally matched with the gear disk (24) as well as a rotating arm (26) fixedly connected with the rotating frame (27), wherein a rotating driving motor (28) is fixedly arranged on the rotating frame (27) and meshed with the gear disk (24) through a pinion (29) fixedly connected with the rotating driving motor (28) so as to drive the rotating frame (27) and the rotating arm (26) to rotate.

Description

technical field [0001] The invention belongs to the field of construction machinery, in particular to a tower crane device and an operating method thereof. Background technique [0002] The gear plate of the tower crane is often exposed to the operating environment, so it is easily polluted by solid dirt such as sand and gravel. [0003] When the tower crane is polluted in this way, it will produce squeaking noise during operation, which will affect the normal use of the equipment, cause safety hazards and shorten the service life. Contents of the invention [0004] The purpose of the present invention is to provide a tower crane device and its operation method, so as to overcome the defects of the prior art. [0005] A tower crane device according to the present invention comprises a main tower body, a sheath set on the top of the main tower body, a gear plate fixedly mounted on the top end of the sheath, a turntable rotatably matched with the gear plate, and a turntable...
