Description

Technical Field

[0001] The utility model relates to the technical field of municipal engineering construction, in particular to a protection structure for municipal engineering construction. Background Technique

[0002] The protection structures in municipal engineering construction are mainly to ensure construction safety, prevent damage to the surrounding environment and personnel during construction, and at the same time protect construction personnel and equipment from external factors. They usually include fences, warning signs, safety nets, temporary support structures, etc., aiming to provide physical isolation for the construction area, control access to the construction area, and provide necessary safety protection for construction personnel and the public.

[0003] There is a Chinese patent with the publication number CN217129158U and the name of a road protection structure for municipal highway engineering construction, including a base, the top of the base is fixedly connected with a bottom plate, the top of the bottom plate is fixedly connected with a column, and the top of the column is fixedly connected with a top plate. The advantages of the utility model are as follows: Rotate the inner hexagonal pin with a hexagonal wrench until the positioning hole faces downwards and is directly opposite to the positioning pin, and the positioning pin is inserted into the positioning hole under the action of the spring. At this time, the two guardrails are firmly connected. This guardrail connection abandons the use of bolt connection and only requires two steps. The first is to operate the dial plate, and the second is to rotate the inner hexagonal pin. The workload is small when laying a large number of guardrails, and the assembly and laying are convenient and fast; after the construction is completed, move the dial plate downwards, the spring is pressed down, the positioning pin is separated from the positioning hole, and at this time, pull out the inner hexagonal pin of another guardrail and sequentially pull out the inner hexagonal pins of the guardrails on both sides, so as to quickly separate multiple guardrail structures, and the disassembly and removal speed is fast. The guardrail in this patent cannot be extended, which will cause it to not fit in some narrow scenarios, thus expanding the interception range, resulting in additional workload and reducing work efficiency.

A fixing column is fixedly connected to the side wall of the pulling plate. One end of the fixing column penetrates through the upper U-shaped frame and is inserted into the special-shaped through groove. Two clamping blocks are fixedly connected to the side wall of the fixing column away from the pulling plate.

[0008] As a further improvement of the utility model, the connecting component includes a pull-ring block arranged on one side of the upper U-shaped frame. A fixing groove is opened on the side wall of the upper U-shaped frame. A T-shaped block is slidably connected in the fixing groove. The pull-ring block is fixedly connected to the T-shaped block. One end of the T-shaped block away from the pull-ring block penetrates through the side wall of the fixing groove and extends into the plug-in groove. Two circular grooves are opened on the side of the T-shaped block away from the pull-ring block. Springs are fixedly connected to the inner side walls of the two circular grooves. The other ends of the springs are fixedly connected to the side wall of the fixing groove.

[0009] As a further improvement of the utility model, two support plates are fixedly connected to both sides of the lower U-shaped frame.

[0010] As a further improvement of the utility model, the number of the outer guardrails is eight, and the shape is a rectangular structure.

[0011] As a further improvement of the utility model, the size of the end of the T-shaped block extending into the plug-in groove matches the size of the rectangular through groove.

[0012] The beneficial effects of the utility model:

[0013] By setting the upper U-shaped frame, the lower U-shaped frame, the inner guardrail, the outer guardrail, and the plug-in component, by pulling out the inner guardrail from the plurality of outer guardrails, the overall length of the guardrail can be extended. Then, the fixing column is inserted into the special-shaped through groove. Subsequently, by rotating the pulling plate, the two clamping blocks on the fixing column can be rotated together. After the two clamping blocks are rotated, they will fit with the upper U-shaped frame, thereby clamping the fixing column in the special-shaped through groove, which can quickly adjust and fix the length of the guardrail and improve the applicability.

[0014] By setting up the connecting component, upper U-shaped frame, inserting block, and inserting slot, pulling the pull ring block to extract the T-shaped block from the inserting slot, then inserting the inserting block into the inserting slot, and then releasing the pull ring block, the T-shaped block will be inserted back into the inserting slot under the action of the spring.
