Problems solved by technology
The assembly process of the above-mentioned crane main girder has the following defects: the installation between the lower cover plate, upper cover plate, left and right webs and ribs of the crane main girder is all done manually, and the installation labor intensity is high and the installation efficiency is high. Low, especially the adjustment between the web and the ribs, it is necessary to manually beat the web to adjust the position between the two, the installation is more troublesome, the labor intensity is greater and the installation efficiency is lower

Embodiment Construction
[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0018] see Figure 1 to Figure 3 As shown, the crane girder hydraulic assembling machine of the present invention includes an assembling frame 1 and a controller. The assembly frame 1 is provided with a channel 2 for the main girder of the crane to pass through. The assembly frame includes two uprights and a top beam arranged between the two uprights. Both columns of the assembly frame 1 are provided with side hydraulic devices for pressing the web when the main girder is assembled. The top beam of the assembly frame 1 is provided with a top hydraulic device for pressing the lower cover when the main beam is assembled. Both the side hydraulic device and the top hydraulic device are electrically connected to the controller. The base plate is arranged between the bottom ends of the two columns of the assembly frame, and the base plate is loca...

The invention discloses a hydraulic erector for a main beam of a crane. The hydraulic erector for the main beam of the crane is characterized by comprising an erecting frame (1) and a controller, wherein the erecting frame (1) is provided with a passage (2) where the main beam of the crane passes and comprises two stand columns and a top beam arranged between the two stand columns, the two stand columns of the erecting frame (1) are each provided with a lateral hydraulic device used for pressing a web in the erecting process of the main beam, a top hydraulic device used for pressing a lower cover plate in the erecting process of the main beam is arranged on the top beam of the erecting frame (1), and the lateral hydraulic devices and the top hydraulic device are all electrically connected with the controller. The hydraulic erector enables the lower cover plate, an upper cover plate, the web and a rib plate to be conveniently installed, can effectively relieve labor intensity and can improve work efficiency.
Description
technical field [0001] The invention relates to the mechanical field, and more specifically relates to a crane main girder hydraulic assembling machine. Background technique [0002] The main girder is the main force-bearing element in the bridge crane frame, which is composed of the lower cover plate, the upper cover plate, two left and right webs and several ribs. The lower cover is installed on the bottom of the left and right webs; the upper cover is installed on the top of the left and right webs; several of the ribs are installed on the lower In the space formed by the cover plate, the web and the upper cover plate, the ribs are used to support the upper cover plate, the web plate and the lower cover plate. The assembly process of the main girder of the crane in the prior art is as follows: firstly, the upper cover plate is placed on the ground; Then use a crane to lift the web and adjust the position of the web so that it is close to one side of each rib. If the web...
