Embodiment Construction

[0021] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many ways other than those described here, and those skilled in the art can make similar improvements without departing from the connotation of the present invention, so the present invention is not limited by the basic implementation disclosed below.

[0022] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other e...

Abstract

The invention belongs to the technical field of hoisting, and specifically relates to a crane. The crane comprises a base and a main beam, wherein a first sliding rail and a second sliding rail are arranged on the main beam; a first walking trolley used for hoisting a workpiece is slidably arranged on the first sliding rail; a second walking trolley used for hoisting the workpiece is arranged on the second sliding rail; an arc transition rail used for communicating the first sliding rail with the second sliding rail is further arranged on the main beam; an auxiliary rotating assembly is arranged at the position, on the arc transition rail, of the main beam; during use, the first walking trolley and the second walking trolley can hoist materials separately, and can walk to the same slidingrail for cooperative operation under the auxiliary effect of the auxiliary rotating assembly, so vertical lifting and hoisting working for a slender part is realized.

Description

technical field [0001] The invention belongs to the technical field of lifting, and in particular relates to a crane. Background technique [0002] At present, cranes are widely used in aviation, aerospace, nuclear power and other fields, and can carry out vertical lifting and horizontal transportation within the setting range. Efficiency, in the prior art, the patent document with the authorized announcement number of CN100460305C discloses a rail-mounted double-car gantry container crane, and specifically discloses that the main girder is provided with two lifting trolleys, and the double trolleys are respectively provided with independent tracks. And they are respectively connected with their respective hoisting drive mechanism, trolley running mechanism, hoisting wire rope winding system and spreader suspension system. However, when hoisting slender parts, it is necessary to hook both ends of the slender parts to ensure that the workpiece can be transported stably durin...
