Description

Technical Field

[0001] This utility model relates to a lifting device, specifically, to a ton bag transfer crane. Background Technology

[0002] In industrial production, raw materials are often transported using ton bags. To facilitate the movement and transfer of ton bags, lifting equipment is typically used. For example, Chinese Patent CN222331407U discloses a ton bag material transport trolley for easy unloading. After the ton bag is lifted by a hook, the extension arm can be driven by the threaded engagement between the screw and the internal threaded tube. During the movement, the extension arm can use the hook to lift the ton bag off the base. However, the single hook structure connected to the ton bag makes the bag unstable during movement and prone to swaying.

[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 ton bag transfer crane.

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

[0006] A ton bag transfer crane includes a trolley travel rail installed on the upper part of the factory building. A bridge frame is mounted on the trolley travel rail, and a trolley travel mechanism is installed on the lower side of the bridge frame. The trolley travel mechanism cooperates with the trolley travel rail. A lifting trolley is installed on the bridge frame, and a trolley travel rail is installed on the upper side of the bridge frame. A trolley travel mechanism is installed on the lower side of the lifting trolley, and the trolley travel mechanism cooperates with the trolley travel rail. The lifting trolley includes a trolley frame, a lifting drum installed on the upper side of the trolley frame, a guide frame installed in the middle of the trolley frame, and a vertical guide column that slides with the guide frame. The lower end of the vertical guide column is connected to a suspension frame. A pulley block is installed on the upper side of the suspension frame, and the lifting drum is connected to the pulley block by a wire rope. A ton bag hook is installed on the lower side of the suspension frame, and a drive motor is installed on the suspension frame corresponding to the ton bag hook. The drive motor is used to drive the ton bag hook to open or close.

[0007] Two sets of symmetrical mounting seats are provided on the lower side of the suspension frame. Each mounting seat is equipped with a ton bag hook. The ton bag hook includes two symmetrically arranged L-shaped hooks. The upper end of the L-shaped hook is connected to a rotating shaft, which is rotatably connected to the mounting seat. The mounting seat is equipped with a drive motor to drive the rotating shaft to rotate. When the vertical part of the L-shaped hook is in a vertical state, the two symmetrical L-shaped hooks form a U-shaped structure.

[0008] Two shafts located on the same mounting base are connected to transmission gears at one end, and the two rotating gears mesh; the other end of one of the shafts is connected to the output end of the drive motor.

[0009] The horizontal portions of the two L-shaped hooks located on the same mounting base are provided with corresponding notches. When closed, the horizontal portions of the two L-shaped hooks overlap.

[0010] The trolley frame has a mounting hole in the middle. The guide frame passes through the mounting hole. The upper end of the guide frame is located above the trolley frame, and the lower end of the guide frame is located below the trolley frame. The middle part of the guide frame is fixedly connected to the trolley frame.

[0011] The guide frame includes rectangular steel with a rectangular through hole in the center. The upper end of the vertical guide post extends into the interior of the rectangular through hole and slides into the rectangular steel.

[0012] The outer wall of the rectangular steel is equipped with a reinforcing plate, which connects the rectangular steel to the trolley frame. The inner wall of the rectangular steel is equipped with several guide wheels, which are tangent to the vertical guide column.

[0013] Compared to existing technologies, the advantages of this invention are that it provides a convenient ton bag transfer crane for ton bag transfer processes, preventing swaying during the transfer. Specifically, the crane is installed on the upper part of the factory building. After the ton bag hook lifts the ton bag, the lifting drum is activated to raise the ton bag to a suitable height. The trolley travel mechanism and the auxiliary trolley travel mechanism move the ton bag to a suitable position, and then the ton bag is lowered to the suitable position. The ton bag hook then releases the ton bag lifting lugs; then the next ton bag is moved. Attached Figure Description
