Description

Technical Field

[0001] This utility model relates to the technical field of aerial work platforms, and in particular to a quick-locking mechanism for detachable safety guardrails on aerial work platforms. Background Technology

[0002] To ensure the safety of workers on aerial work platforms, guardrails are installed on the platforms. Traditional guardrails are fixed to the platform with bolts via a bottom bracket, requiring many mounting holes to be drilled on the platform, which affects the platform structure. Moreover, the disassembly and installation of guardrails is cumbersome and involves a large amount of work. Utility Model Content

[0003] This utility model aims to address the shortcomings of existing technologies by providing a detachable safety guardrail quick-locking mechanism for aerial work platforms.

[0004] To achieve the above objectives, this utility model adopts the following technical solution:

[0005] The aerial work platform's detachable safety guardrail quick-locking mechanism includes a first mounting base symmetrically installed on the left and right sides of the platform, and a second mounting base symmetrically installed on the front and rear sides of the platform.

[0006] The first mounting base includes a first U-shaped clamp plate, which is inserted into the side of the platform. The bottom of the first U-shaped clamp plate is provided with a first connecting plate. Several first connecting rods are passed between the first connecting plates of the two first mounting bases. The two ends of the first connecting rods are tightened with first fixing nuts. The top of the first U-shaped clamp plate is provided with a first locking seat, and the first locking seat is provided with a first inverted T-shaped mounting groove.

[0007] The second mounting base includes a second U-shaped clamp plate, which is inserted into the side of the platform. The bottom of the second U-shaped clamp plate is provided with a second connecting plate. Several second connecting rods are passed between the second connecting plates of the two second mounting bases. The two ends of the second connecting rods are tightened with second fixing nuts. The top of the second U-shaped clamp plate is provided with a second locking seat, and the second locking seat is provided with a second inverted T-shaped mounting groove.

[0008] Guardrails are installed in both the first and second inverted T-shaped mounting slots. Locking blocks are installed on both sides of the guardrails on the first and second locking seats. The locking blocks are installed on the first and second locking seats by locking bolts.

[0009] The guardrail consists of several guardrail frames, each with an inverted T-shaped insert at its bottom, which is installed in the first and second inverted T-shaped mounting slots.

[0010] The upper end of the connecting side of the adjacent guardrail frame is provided with an arc-shaped groove, the inner side of the arc-shaped groove is provided with a locking groove, and a locking rod is inserted between the two corresponding arc-shaped grooves. The two ends of the side wall of the locking rod are provided with locking ridges that cooperate with the locking groove.

[0011] The first connecting plate and the second connecting plate are at different heights, and the first connecting rod and the second connecting rod are installed vertically to avoid each other.

[0012] The beneficial effects of this utility model are: the installation of the guardrail does not require drilling many threaded holes on the platform, and will not damage the structure of the platform. The guardrail uses multiple guardrail frames to be inserted into the corresponding first and second mounting seats, and finally locked with locking blocks. The installation and disassembly are convenient. Adjacent guardrail frames can also be locked with locking rods, making it more stable. Attached Figure Description
