Embodiment Construction

[0026] Depend on Figure 1-Figure 11 The slewing crane shown includes a vertical slewing column 2 driven by a power device 4. The power device 4 is a three-in-one deceleration device composed of a motor, a reducer and a brake connected in sequence. The three-in-one deceleration device passes through The gear transmission drives the rotary column 2, the gear transmission includes a pinion 5 and a large gear 6, the large gear 6 is fixed at the bottom of the rotary column 2, that is, the power device 4 transmits the large gear 6 at the bottom of the rotary column 2 through the small gear 5, The bull gear 6 drives the rotary column 2 to rotate again. The vertical central axis of the revolving column 2 is the revolving centerline 7 .

[0027] The top of the slewing column 2 is fixedly connected with the slewing arm 12 through the slewing bracket 1, the slewing bracket 1 extending vertically upwards is fixed on the top of the slewing column 2, the slewing arm 12 extends horizontall...

The rotating crane of the present invention is a rotating crane with advantages of low cost, easy installation, easy maintenance, and safe use.

Description

technical field [0001] The invention relates to a slewing crane, in particular to a slewing crane equipped with a gantry crane. Background technique [0002] The slewing support device of the existing slewing crane is a slewing device composed of a large slewing bearing installed on the column. The diameter of the large slewing bearing is more than 1 meter. The large slewing bearing is expensive and requires high machining accuracy. , and the maintenance cost is also high. Therefore, low cost, easy installation, easy maintenance, and safe use have become the innovation goals of slewing crane equipment. Contents of the invention [0003] The object of the present invention is to provide a slewing crane with low cost, easy installation, easy maintenance and safe use. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: a slewing crane, including a slewing column driven by a power device, a horizontal slewing arm is ...
