Description

Technical Field

[0001] This utility model relates to a lifting device, specifically, to a downward slewing anti-sway electromagnetic hanging beam crane. Background Technology

[0002] A crane, also known as an overhead crane, gantry crane, or hoist, is a multi-action lifting machine that vertically lifts and horizontally moves heavy objects within a certain range. A crane mainly consists of a hoisting mechanism and a lifting device, where the lifting device is used to connect to the heavy object for lifting. Currently, there are many types of lifting equipment on the market. To adapt to different working conditions and increase the flexibility of lifting heavy objects, some cranes have added a rotation function to the traditional lifting device. For example, Chinese patent CN221836540U discloses an intelligent electromagnetic chuck crane, Chinese patent CN221777395U discloses a bridge installation lifting device, and Chinese patent CN221343541U discloses a crane slewing device. These lifting devices mostly include a lower lifting mechanism connected to the heavy object and an upper lifting structure connected to the hoisting mechanism. The lower and upper lifting structures are simply connected by a single rotating shaft, resulting in relatively poor stability during rotation.

[0003] In order to solve the above problems, people have been seeking an ideal technological solution. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a downward slewing anti-sway electromagnetic girder crane.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A bottom-slewing anti-sway electromagnetic girder crane includes a bridge frame and a lifting trolley. The lifting trolley includes a trolley frame and a winch mounted on the upper side of the trolley frame. Several symmetrical lifting device links are arranged on the lower side of the trolley frame, and each lifting device link is slidably connected to a lifting device guide column. The lifting device guide columns are connected by a first lifting device crossbeam. Lifting pulleys are arranged at both ends of the first lifting device crossbeam. The lifting pulleys and the winch are connected by wire ropes. A circular track is arranged on the lower side of the first lifting device crossbeam. A second lifting device crossbeam is arranged below the circular track. Several lifting mechanisms are evenly arranged on the lower side of the second lifting device crossbeam. The upper middle part of the second lifting device crossbeam is rotatably connected to the middle part of the first lifting device crossbeam. Two sets of symmetrical slewing wheels are arranged on the upper side of the second lifting device crossbeam. The slewing wheels travel along the circular track and are connected to a slewing motor.

[0007] Two sets of symmetrical mounting seats are set on the upper side of the second lifting beam. Mounting plates are set on the inner and outer sides of the mounting seats corresponding to the circular track. Each of the two mounting plates is connected to a set of slewing wheels. The slewing wheels on the outer side are connected to the slewing motor.

[0008] The middle of the lifting rod is provided with a symmetrical connecting platform. The upper side of the connecting platform is connected to the lower side of the trolley frame by a reinforcing rod, which is inclined.

[0009] Each lifting rod has a vertical groove with an open lower side. Inside the vertical groove are several guide wheels, which are tangent to the side of the lifting rod guide column.

[0010] The underside of the trolley frame is equipped with trolley traveling wheels and fixed pulleys. The trolley traveling wheels cooperate with the trolley track, and the wire rope led out by the winch passes through the fixed pulley and the lifting pulley in sequence.

[0011] The trolley frame includes a support plate and two sets of trolley end beams and trolley cross beams located on the underside of the support plate. The winch is fixed to the support plate. Trolley wheels are installed on the underside of the trolley end beams. The trolley cross beams are perpendicular to the trolley end beams.

[0012] The cable tray includes two sets of oppositely arranged trolley end beams, which are connected by two sets of parallel main beams. Trolley tracks are set on the upper side of the two sets of main beams respectively. The trolley traveling wheels of the lifting trolley travel along the trolley tracks. Trolley horizontal wheels are set at both ends of the trolley end beams corresponding to the two sides of the trolley tracks respectively.

[0013] The underside of the trolley end beam is equipped with trolley traveling wheels, and mounting brackets are installed at both ends of the trolley end beam. Trolley buffers are installed on the upper side of the mounting brackets, and trolley horizontal wheels are installed at the bottom of the mounting brackets.

[0014] Compared to existing technologies, the advantages of this invention are as follows: This invention provides a lower-slewing anti-sway electromagnetic hanging beam crane. During use, the crane connects to the object to be lifted via the lifting structure on the lower side of the second lifting beam. When the object needs to be rotated, the slewing motor drives the slewing travel wheel on the upper side of the second lifting beam to travel along the circular track, achieving the purpose of angle adjustment and fully ensuring the stability of the adjustment process. Simultaneously, a lifting rod is installed on the lower side of the trolley frame, and a lifting guide column is installed on the upper side of the first lifting beam. As the object moves up and down, the lifting guide column and the lifting rod slide together to prevent swaying during lifting. Attached Figure Description
