Abstract
Description
Technical Field
[0001] This utility model relates to the field of elevator mobility technology, specifically a movable base for an elevator. Background Technology
[0002] The mobile base of the lifting platform is a core component ensuring the flexibility and safety of the equipment. It typically consists of a high-strength frame, lockable casters, anti-slip support mechanisms, and a power system. Its design combines ease of movement with operational stability: the bottom casters support 360-degree rotation, facilitating quick positioning in confined spaces; during operation, cylinders drive anti-slip mechanisms such as rubber pads or hydraulic outriggers to press down, increasing friction or directly contacting the ground to fix the platform and prevent slippage. Some high-end models are also equipped with a drive motor and steering system, enabling electric movement and precise steering, further reducing operational intensity. This structure not only improves the efficiency of high-altitude operations but also ensures safety through a dual anti-slip mechanism.
[0003] In existing technologies, the mobile base of a lift generally relies on only four outriggers for support. On soft, uneven ground, if the outriggers are in contact with the ground, it is easy to cause instability. During the use of the lift, even a slight tilt will be magnified by the height. Therefore, we need a mobile base for the lift. Utility Model Content
[0004] The purpose of this invention is to provide a movable base for an elevator to solve the existing problems mentioned in the background art.

One end of the connecting rod is fixedly connected to a first bevel gear, and a second bevel gear is meshed with one side of the first bevel gear. A fixed rod is fixedly connected inside the second bevel gear. A movable disc is fixedly connected to the bottom of the fixed rod. A movable column is movably connected to the bottom of the movable disc. A movable plate is fixedly connected to the bottom of the movable column. A sliding rod is slidably connected inside the movable plate. A support plate is fixedly connected to one side of the movable plate. A fixed shell is movably connected to the outer wall of the support plate. A connecting plate is movably connected to the inner wall of the fixed shell. A support column is fixedly connected to one end of the connecting plate. A positioning screw is provided at the top of the support column. A mounting base plate is movably connected to the inner wall of the support column.
[0009] Preferably, the motor forms a rotating structure with the first bevel gear via a connecting rod, and one end of the connecting rod is connected to the output end of the motor, while the other end of the connecting rod is connected to the center position of the first bevel gear via a keyway.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the movable base of this elevator, (1) After the support frame is started, the support frame drives the transmission link to move in the connecting block, which in turn drives the limiter and the fixed column to move synchronously. At this time, the starting adjustment screw rotates. Using the thread structure, the fixed column drives the adjustment column to move up and down along its inner wall. The adjustment column drives the support base plate to move down, so that the support base plate tightly presses against the ground and achieves stable fixation. This process accurately controls the position and pressure of the support base plate through mechanical linkage and thread adjustment, providing reliable support for the overall equipment, effectively enhancing the stability of the equipment, reducing the risk of shaking and displacement, and ensuring the normal operation of the equipment. (2) After starting the motor, the motor output shaft drives the connecting rod, which rotates through the meshing of the first and second bevel gears, and smoothly transmits the power to the fixed rod, causing the movable disc to rotate. The movable disc drives the movable column, which pushes the movable plate to move linearly along the slide rod, and then pushes the support plate. The support plate extends and retracts through the fixed shell, pushing the support column. Finally, the rotating positioning screw drives the mounting base plate to press against the ground for fixation. The entire process is precise and efficient in power transmission, achieving stable support and flexible positioning of the equipment, effectively improving the stability and reliability of the equipment operation, and reducing shaking and displacement.
