Description

Technical Field

[0001] The invention relates to the technical field of warehousing logistics, and in particular to a gantry elevator. Background Art

[0002] In the field of logistics sorting, the current market has deviations in the height of the lines due to cross-regional factories or civil engineering reasons. Some of them need to be connected to other functional integrated equipment, such as film wrapping machines, which require a height difference from the height of the line itself. Suitable lifting equipment is needed to solve this difference. However, the market is full of large-scale cross-floor lifting equipment, which is costly and has high installation and civil engineering requirements, and cannot solve this kind of problem well.

[0003] With the development of modern science and technology and people's increasing demand for material things, there are higher requirements for the speed and efficiency of logistics. Elevators are mechanical equipment that transports goods by changing potential energy. The transportation process is completed by dragging the transported goods up and down by power machinery, which is called lifting. In the logistics industry, there is a large demand for elevators.

[0004] The Chinese patent application number 202310638575.5 discloses a cargo elevator, a cargo elevator device and a storage system. The cargo elevator disclosed above includes a stand, a cargo platform, a lifting drive device and a translation drive device. The cargo platform is arranged on a guide frame; the lifting drive device is used to drive the guide frame to perform lifting and lowering movements along the height direction of the stand; the translation drive device is used to drive the cargo platform guide frame to perform translational movements in the length direction. A cargo platform is arranged on each stand, and the cargo platform can be lifted and lowered along the stand and can be translated along the guide frame. Therefore, when multiple elevators are arranged, multiple cargo platforms in the multiple elevators can avoid each other by translating on the guide frame when they are lifted and lowered to the same height. A Chinese patent with application number 202211611530.0 discloses a logistics cargo elevator. The above-mentioned cargo elevator includes a hoist body and a servo motor. A mounting rod is fixedly connected to one side of the hoist body, and a mounting plate is fixedly installed on the mounting rod. A foot seat is fixedly connected to the bottom end of the hoist body, a support rod is fixedly installed on the hoist body, a cross rod is fixedly installed on the top of the support rod, a fixing rod is fixedly connected to one side of the support rod, a handle is fixedly installed on the fixing rod, and a control console is fixedly installed on one side of the support rod.

[0005] In the above-disclosed prior art, independently operated guide frames are respectively provided on both sides of the vertical frame, the cargo platform is arranged on the guide frames, and the lifting drive device drives the guide frames to realize the lifting and lowering of the cargo. During the lifting and lowering of the cargo, since one side of the guide frame is connected to the vertical frame and the other side is suspended in the air, the force at the connection between the guide frame and the vertical frame is relatively large. When the weight of the cargo is large, the connection is prone to jamming or the guide frame tilting during the lifting process, which makes it easy for the cargo to fall from the cargo platform. At the same time, since only one side of the guide frame is connected to the column, the stability of the guide frame is poor during the lifting and lowering of the cargo, which makes it easy for the cargo to shake, which is not conducive to the safe transportation of the cargo. Summary of the invention
