Embodiment Construction

[0018] In order to deepen the understanding of the present invention, the present invention will be described in further detail below. This embodiment is only suitable for explaining the present invention, and does not constitute a limitation to the protection scope of the present invention.

[0019] The invention provides a method for installing a trolley track under an inverted trapezoidal single girder gantry crane with an end face, and the specific steps are as follows:

[0020] (1) if Figure 1-4 As shown, after the closing of the main girder 6 of the gantry crane is completed, use a 12t forklift 4 to place a single track with a length of 12m on the installation surface of the lower trolley track 1. In order to increase the lifting height of the forklift 4, use the track on the fork of the forklift 4 Lifting frame 3;

[0021] (2) According to the welding form of the 1 pair interface of the lower trolley track, lengthen the 12m single track to make the whole track a whole...

Abstract

The invention provides a method for installing lower trolley tracks of a single-main-girder gantry crane with an inverted trapezoidal end surface. The method includes 1, the lower trolley tracks, 2, main girder side surface platform channels, 3, a track lifting frame, 4, a 12t forklift, 5, a track lifting ring, 6, gantry crane main girders, 7, main girder closing piers and 8, track pressing plates. According to the method, the lifting frame is arranged on forks of the forklift to increase the lifting height of the forklift, and the influence of the main girder side surface platform channels onlifting tracks of ordinary cranes is eliminated. A single 12m steel rail is installed in place after the length is extended, and the track installation time is saved.

Description

technical field [0001] The invention relates to a method for hoisting and installing a track of a trolley under a gantry crane with a large tonnage and a single main girder, in particular to a method for installing a track of a trolley under a gantry crane with an inverted trapezoidal end face. Background technique [0002] Large-scale single girder gantry cranes are installed with upper and lower trolley tracks after the main girders are closed. The cross section of the main girder of single main girder gantry cranes is mostly an inverted trapezoidal shape, and the two sides of the main girder have platform passages above the lower trolley tracks. The platform channel is generally installed in place when the main girder is made in sections, which affects the lifting of the trolley track after the main girder is closed. [0003] Therefore, it is necessary to provide a new technical solution to solve the track installation problem. Contents of the invention [0004] Aiming...
