Abstract

The invention relates to a tower crane apparatus with characteristics of self-cleaning achieving and easy replacing, and an operating method thereof. The tower crane apparatus comprises a main tower body (21), a sleeve frame (22) sleeved on the top portion of the main tower body (21), a gear disk (24) fixedly arranged on the top end of the sleeve frame (22), a rotation frame (27) forming rotary matching with the gear disk (24), and a rotary arm (26) fixedly connected with the rotation frame (27), wherein a rotation drive motor (28) is fixedly arranged on the rotation frame (27), and drives the rotation frame (27) and the rotary arm (26) to rotate through the engagement between a small gear (29) fixedly connected with the rotation drive motor and the gear disk (24).

Description

technical field [0001] The invention belongs to the field of construction machinery, in particular to a tower crane capable of self-cleaning and easy to replace 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 object of the present invention is to provide a self-cleaning and easy-to-replace tower crane device and its operation method, so as to overcome the defects of the prior art. [0005] A self-cleaning and easy-to-replace tower crane device according to the present invention includes a main tower body, a sleeve frame set on the top of the main tower body, a gear plate fi...
