Description

Technical Field

[0001] The utility model belongs to the technical field of scissor lift platforms, and more specifically, it particularly relates to a high-performance hydraulically-driven scissor-type aerial work platform. Background Art

[0002] With the development of modern industrialization and urbanization, the demand for aerial work is increasing day by day. Therefore, the high-performance hydraulically-driven scissor-type aerial work platform has gradually replaced the traditional aerial work method with its characteristics of high efficiency, safety, and stability. It is a special equipment widely used in various aerial work occasions. The existing high-performance hydraulically-driven scissor-type aerial work platform mainly consists of a hydraulic drive mechanism and a scissor mechanism, and the lifting of the platform is realized by driving the expansion and folding of the scissor mechanism through the hydraulic drive mechanism.

[0003] The existing Chinese patent application No. CN202020656312.9 discloses a self-propelled scissor-type aerial work platform, which includes wheels, a chassis, a mounting seat, and a workbench. A drive assembly is fixedly arranged in the chassis, and four wheels are rotatably connected to the bottom end of the drive assembly. The wheels are evenly distributed. An inspection door is arranged in the middle of the chassis relative to the front and rear wheels. A front chassis is fixedly connected to the front of the chassis. A mounting seat is fixedly connected directly above the chassis. Two groups of guide rails are horizontally arranged in the mounting seat. The guide rails are horizontal in the direction of the device's travel, and two connecting rods are installed in each guide rail. Hydraulic motors are fixedly connected to the outer sides of the connecting rods. Scissor rods are sleeved on the connecting rods. Hinge points are arranged at the joints of the scissor rods. Scissor rods are also hinged at the ends of the scissor rods. A limiting rod is slidably connected to the middle of the scissor rods. In this utility model, when ensuring the fast and stable lifting of the platform, the device below can be moved on the platform, which is convenient for maintenance.

[0004] Based on the above, most of the existing high-performance hydraulically-driven scissor-type aerial work platforms use rollers for fast movement. Although the rollers greatly improve the flexibility of the work platform, when the roller structure is used in scenarios where the ground is uneven or the soil is soft, the structural stability is poor, and it is easy to tilt or shake. Some work platforms are equipped with support legs, but they need to be manually unfolded, and the operation is relatively cumbersome, affecting the use efficiency. Summary of the Utility Model
