Description

Technical Field

[0001] The utility model relates to the technical field of lifting platforms, in particular to a lifting platform which is easy to move. Background Art

[0002] A lift is a lifting machinery that transports people or objects vertically. It is used to carry objects and move them in the vertical direction. It is usually hydraulically driven, and the hydraulic energy is converted into mechanical energy through the hydraulic cylinder to control the movement of the lift. In practical applications, lifts have a wide range of uses. For example, in factories, warehouses, construction sites and other places, they are used to lift goods or people to different heights.

[0003] Due to the complexity and variability of application scenarios, the lifting platform usually needs to be moved according to actual needs during use. Existing lifting platforms usually install multiple pulleys under the base to push the lifting platform as a whole to the working area to meet the lifting of people or goods. However, when placed later, it only relies on the self-locking device on the pulley for fixing. It cannot maintain good stability when lifting heavier objects. When the center of gravity shifts, it will apply greater pressure to one side of the pulley, causing the pulley to rotate, which poses certain safety hazards. In view of this, the present application proposes a lifting platform that is easy to move. Utility Model Content

[0023] By installing two reinforcing plates 5 on the side walls of the first frame 3 , the structural strength of the installation point of the first frame 3 and the connecting seat 4 can be increased, and the bearing capacity of the first frame 3 during the lifting process can be improved.

[0024] The connecting seat 4 includes an insert ring and fixed seats arranged on both sides, and a pin is commonly arranged between the insert ring and the two fixed seats, and the insert ring and the two fixed seats are rotatably connected with the pin.

[0025] Through the connection of the pins, the insert ring can flexibly adjust the angle between the two fixing seats, so as to cooperate with the first hydraulic cylinder 12 to enable the first support rod 6 and the second support rod 8 to complete the lifting of the upper operating platform 14.

[0026] The sliding assembly includes a connecting rod 9 , which is connected to the two second support rods 8 . Pulleys 10 are respectively installed on both sides of the connecting rod 9 , and the two pulleys 10 are both arranged in the first frame 3 .
