Description

Technical Field

[0001] This utility model relates to the field of work platform technology, specifically a multifunctional work platform protective top cover structure. Background Technology

[0002] Work platforms are mobile high-altitude operations that serve various industries, such as high-altitude work, equipment installation, and maintenance. When using work platforms, a protective top cover structure is required to protect the platform.

[0003] Currently, there are two main types of work platform covers: one is a vertical lifting type, and the other is a rotating type. While the vertical lifting type can adjust the height according to different working conditions, it results in a small working area and inconvenient construction. The rotating type requires the cover to be flipped back and forth during operation, which cannot effectively protect workers and poses a risk of falling rocks in the tunnel. On the other hand, rotating the cover requires a certain amount of space, and the boom must be lowered first before the cover is flipped according to the height. This results in high workload, low efficiency, and significant safety hazards. To solve these problems, we have proposed a multi-functional protective cover structure for work platforms. Utility Model Content

[0004] The purpose of this utility model is to provide a multifunctional protective top cover structure for a work platform to solve the problems currently found in the market as described in the background.

The top of the column is fixedly connected to a mounting base. The suspended basket frame is connected to the mounting base through a first telescopic hydraulic cylinder. An outer slide rail is installed on the top of the mounting base. An inner slide rail is slidably arranged on the inner side of the outer slide rail. The outer slide rail and the inner side of the inner slide rail are connected through a second telescopic hydraulic cylinder. The top of the inner slide rail is fixedly connected to a top cover mounting bracket, and a protective top cover is fixedly installed on the top of the top cover mounting bracket. The inner slide rail is symmetrically connected to the side of the outer slide rail, and the pulleys are installed on the outside of the inner slide rail through a mounting assembly.

[0006] Preferably, the column is rectangular and the external dimensions of the column match the internal dimensions of the lifting groove.

[0007] Preferably, both the outer slide rail and the inner slide rail are U-shaped, and the outer width of the inner slide rail matches the inner width of the outer slide rail.

[0008] Preferably, the top cover mounting bracket and the protective top cover are fixedly connected by bolts.

[0009] Preferably, two sets of pulleys are provided on both sides of the inner slide rail.
