Description

Technical Field

[0001] This utility model relates to the technical field of suspended double-girder European-style cranes, specifically to a suspended double-girder European-style crane. Background Technology

[0002] Double-girder European-style cranes are used in various fields due to their small size and light weight. The crane is mainly composed of a trolley and a lifting trolley. Double-girder cranes are generally composed of three main parts: mechanical, electrical and metal structure. The appearance of a European-style crane is that of a single-span flat bridge that moves horizontally on two parallel overhead tracks supported at both ends. Double-girder cranes are widely used in indoor and outdoor industrial and mining enterprises, steel and chemical industries, railway transportation, ports and docks and logistics turnover departments and places.

[0003] Existing suspended double-beam European-style cranes cannot be properly adjusted in position and height after installation because their sides are fixed to the mounting brackets or walls. When adjustment is needed, they must be disassembled and reinstalled, which not only increases installation costs but also reduces work efficiency. Therefore, there is an urgent need for a suspended double-beam European-style crane to overcome the above-mentioned defects. Utility Model Content

[0004] The purpose of this utility model is to provide a suspended double-girder European-style crane with the advantage of convenient adjustment, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a suspended double-girder European-style crane, comprising a bridge crane assembly, a first lifting assembly, and a second lifting assembly. The first lifting assembly is disposed on both sides of the top of the bridge crane assembly, and the second lifting assembly is disposed at the center of both sides of the bottom of the bridge crane assembly. The bridge crane assembly includes a bridge frame body, a first moving mechanism, a second moving mechanism, a crane body, and a limiting rail. The first lifting assembly includes a mounting block, a positioning seat, a drive motor, a moving rod, a first slider, a threaded rod, a first sliding groove, and a mounting beam seat. The second lifting assembly includes a receiving seat, a mounting ring seat, a positioning plate, a lifting rod, a second sliding groove, a second slider, and a cylinder.

[0006] Furthermore, a second transfer mechanism is slidably connected to the top of the cable tray body, a crane body is fixedly installed on the top of the second transfer mechanism, and a first transfer mechanism is fixedly installed on both sides of the cable tray body. A limit rail is slidably connected to the bottom of the first transfer mechanism.

[0007] Furthermore, a receiving seat is fixedly installed at the center of the bottom of the limiting track, a cylinder is fixedly installed at the top of the inner cavity of the receiving seat, a lifting rod is fixedly installed at the bottom of the cylinder, and a positioning plate is fixedly installed at the bottom of the lifting rod.

[0008] Furthermore, mounting ring seats are fixedly installed on both sides of the top of the positioning plate, and second sliding grooves are opened on both sides of the inner cavity of the receiving seat. A second slider is slidably connected inside the second sliding groove, and the side of the second slider that is relatively close to it is fixedly connected to both sides of the lifting rod.

[0009] Furthermore, mounting blocks are fixedly installed on both the front and back of the limiting track, a positioning seat is fixedly installed on the top of the mounting block, a drive motor is provided in the inner cavity of the positioning seat, and the bottom of the drive motor is fixedly connected to the top of the mounting block.

[0013] This utility model uses a bridge crane assembly to lift goods, a first lifting assembly to adjust the height of the bridge crane assembly, and a second lifting assembly to adjust and support the bottom of the bridge crane assembly. In use, the mounting ring seat is first fixed with bolts, followed by the top of the mounting beam seat. After installation, when downward adjustment is needed, the drive motor is turned on, causing the threaded rod to rotate, which in turn moves the positioning seat and the bridge frame body downwards. Simultaneously, the cylinder is activated, causing the receiving seat to move downwards, thus preventing the bridge frame body from swaying during lifting and improving its stability during operation. It offers the advantage of convenient adjustment and solves the problem of existing suspended double-European-style cranes, where the sides are fixed to the mounting bracket or wall, making it impossible to adjust the height properly after installation. When adjustment is needed, disassembly and reinstallation are required, increasing installation costs and reducing work efficiency. Attached Figure Description
