Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, and specifically, to a fixing device for a construction engineering lift. Background Art

[0002] The scissor lift is a special equipment for high-altitude operations with wide applications. Its scissor mechanical structure enables the lift table to have high stability during lifting. The wide working platform and high load-bearing capacity allow for a larger high-altitude operation range and are suitable for multiple people to work simultaneously. However, how to improve the stability of the scissor lift base during fixation is an urgent problem to be solved currently.

[0003] After retrieval, the patent with the publication number CN211283636U discloses a new fixing device for a construction engineering lift, which includes a chassis. The upper end of the chassis is fixedly connected with a lifting frame, the upper end of the lifting frame is fixedly connected with a workbench, an electric push rod is further arranged inside the lifting frame, and lifting baffles are arranged on both sides of the lifting frame. The lifting baffle includes a plurality of movable plates connected end to end. The top end of the lifting baffle is fixedly connected to the bottom end of the workbench, and the bottom end of the lifting baffle is fixedly connected to the upper end of the chassis. Four groups of fixing devices are also arranged on the upper end of the chassis. By arranging the lifting baffles on both sides of the lifting frame, when the lifting frame drives the workbench to rise, the lifting baffles are pulled up with the workbench, which can protect both sides of the lifting frame and prevent sundries from entering the lifting frame and affecting the operation. The lift is fixed by the fixing device, and the drill rod is driven by a motor to drill holes in hard ground.

[0004] After pulling out the connecting rod from the slide rail in the above new fixing device for a construction engineering lift, the hydraulic cylinder drives the piston rod to descend, and then the piston rod moves the drill rod downward to complete the ground insertion and fixing work. However, the method of only extending and completing the ground insertion and fixing on both sides of the chassis in this design is relatively single. This design cannot synchronously expand the other two sides of the chassis, resulting in limited contact area between the chassis and the drill rod and the ground. Thus, the chassis may shake when the lifting frame is working. Content of the Utility Model

[0017] In the present utility model, a bidirectional screw rod assembly is provided inside the support base. Through the bidirectional screw rod assembly, two sets of inwardly retractable components can be driven to move away from each other until the inwardly retractable components extend out from the sides of the support base respectively. Subsequently, the support components on both sides inside each inwardly retractable component are activated. The second forward and reverse motor drives the worm to rotate, and then the worm gear meshing on the side of the worm drives the rotating shaft and the support plate located at the top of the rotating shaft to rotate until the two support plates rotate out horizontally on the sides of the inwardly retractable components respectively.
