Embodiment Construction

[0026] The present invention will be further described below in conjunction with specific embodiments and accompanying drawings, but the protection scope of the present invention should not be limited thereby.

[0027] refer to figure 1 with figure 2 , The shipyard gantry crane of the present embodiment includes: main beam 1, rigid leg 2, flexible leg 3, upper trolley 5, lower trolley 6, maintenance crane 7, cart traveling mechanism 8.

[0028] Wherein, the rigid leg 2 and the flexible leg 3 are installed at both ends of the main beam 1 respectively. For example, the flexible leg 3 can be hinged to the main beam 1 through a flexible hinge 4 .

[0029] The lower trolley 5 and the upper trolley 6 are installed on the main beam 1, and the lower trolley 5 and the upper trolley 6 can walk on the main beam 1 independently of each other. The main hooks (not shown in the figure) are respectively arranged under the lower trolley 5 and the upper trolley 6. In this embodiment, the nu...

Abstract

The invention provides a shipyard gantry crane with an upper dolly which is provided with a lifting device. The gantry crane comprises a main beam, a lower dolly and the upper dolly which are arranged on the main beam. The lower and upper dollies are provided with main suspension hooks respectively, and the fixed lifting device is arranged on the upper side of the upper dolly. The gantry crane is capable of lifting goods higher at a low cost.

Description

technical field [0001] The invention relates to a shipyard gantry crane, in particular to a shipyard gantry crane with a trolley and a fixed crane. Background technique [0002] The continuous utilization and development of marine resources by humans has promoted the development of the shipbuilding industry, and the shipyard gantry crane is an important equipment in the shipbuilding industry. The structure of the traditional shipyard gantry crane is usually in the form of an upper trolley and a lower trolley, and the lifting height is generally equal to or less than the height of the lower surface of the main girder. [0003] The current offshore platform and other applications have increasing requirements for the lifting height, and increasing the lifting height by increasing the height of the main girder will significantly increase the cost of the gantry crane in the shipyard. Contents of the invention [0004] The technical problem to be solved by the present invention...
