Description

Technical Field

[0001] The utility model relates to the technical field of aerial work platforms, in particular to a portable and mobile aerial work platform. Background Art

[0002] With the development of social science and technology, the application of lifts is becoming more and more widespread. Whether it is construction, civil engineering, or people's daily life, hydraulic lifting machinery is indispensable. Aerial work platforms are products that serve various industries for high-altitude operations, equipment installation, maintenance, and other mobile high-altitude operations. Currently, there are many types of portable and mobile aerial work platforms on the market, but there are still some shortcomings.

[0003] Existing portable mobile aerial work platforms can adjust the height of the platform by setting a lifting mechanism, so that it can be used for work at different heights. However, since the elevator is set up to move downward, the platform cannot be lowered to the lowest point, which makes it more troublesome for people to enter the top of the platform. At the same time, the size of the platform is limited and its space cannot be expanded. The design has limitations. In addition, after the equipment is moved to the destination, it needs to be stabilized otherwise it is easy to tip over, causing injuries to workers. For example, the Chinese utility model patent with authorization announcement number CN207566822U discloses a mobile aerial work platform, including a support base, a hinge and a protective plate. Grooved seats are installed on both sides of the support base, and the groove seat is connected to an L-shaped support rod. The bottom end of the L-shaped support rod is installed with a support foot. A lift is installed on the surface of the support base, and a hydraulic cylinder is installed on the lift. A work platform is installed on the top of the lift. A telescopic cylinder is installed on the top of the work platform, and the telescopic cylinder is connected to a telescopic rod. The telescopic rod is connected to a handrail. A support column is installed at the center of the work platform, and circular rings are evenly fixed on the surface of the support column. This utility model connects an L-shaped support rod via a grooved seat, and a pin is inserted through a pin hole to securely connect the grooved seat and the L-shaped support rod. The L-shaped support rod securely secures the support base, preventing the aerial work platform from vibrating violently during operation and ensuring its stability. However, this device uses a lifting mechanism to adjust the platform's height, allowing it to operate at different heights. However, since the lift cannot move downward to the lowest point, it is difficult for people to access the platform. At the same time, the platform is limited in size, and its space cannot be expanded. This design has limitations. Therefore, we propose a portable and mobile aerial work platform to address the above-mentioned problems. Utility Model Content
