[0002] Crane refers to a multi-action lifting machine that can lift and carry heavy objects vertically and horizontally within a certain range. It is also called overhead crane, overhead crane, and crane. Some lifting equipment has the working characteristic of intermittent movement, that is, the corresponding mechanisms of taking materials, moving, unloading, etc. work alternately in one working cycle. The development and use of cranes in the market are becoming more and more extensive.
[0003] However, the existing crane bridge needs to bear the weight of the entire cargo during use. When the crane bridge drives the cargo to move to the middle position, the crane bridge bears the greatest load. Since the crane bridge is not load-reinforced, when the crane bridge is in long-term operation, the middle part of the crane bridge is extremely prone to bending. After the crane bridge is bent, the mobile frame has no supporting parts and the crane bridge will pull the mobile frame away from the supporting frame, resulting in poor safety of the crane bridge. Utility Model Content
[0004] In view of the deficiencies in the prior art, the utility model provides a gantry crane bridge to solve the problems that the middle part of the crane bridge is extremely prone to bending due to the lack of load reinforcement of the crane bridge, and after the crane bridge is bent, the mobile frame has no supporting components and the crane bridge will pull the mobile frame away from the supporting frame, resulting in poor safety of the crane bridge.
[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: a gantry crane bridge, comprising a bridge body, both ends of the bridge body are welded and fixedly connected with fixed plates, one side of the fixed plate is fixedly connected with a moving trolley by bolts, the inner side of the moving trolley is respectively fixedly connected with a moving mechanism and a reinforcement plate by bolts, the inner side of the reinforcement plate is fixedly connected with a reinforcement rod, the top of the bridge body is fixedly connected with an upper reinforcement frame, the bottom of the bridge body is fixedly connected with a lower reinforcement frame, the front and back sides of the bridge body are provided with moving grooves, the outer side of the bridge body is movably connected with an adjusting trolley through the moving groove, the front side of the adjusting trolley is fixedly connected with an adjusting mechanism, the inner side of the adjusting trolley is fixedly connected with a rotating shaft through a bearing, the outer sides of the rotating shaft are respectively fixedly connected with a transmission gear and an adjusting wheel, and the bottom of the adjusting trolley is fixedly connected with a lifting mechanism.

[0011] The utility model provides a gantry crane bridge, which has the following beneficial effects:
[0012] The gantry crane bridge has a reinforcement rod, a lower reinforcement frame and an upper reinforcement frame. When the gantry crane bridge is used, the staff starts the lifting body, and the lifting body drives the winding drum to rotate clockwise. At this time, the winding drum releases the sling rope, thereby adjusting the height of the sling rope hook, and then connects the hook with the goods, and then starts the lifting body in reverse.
