Description

Technical Field

[0001] This utility model relates to the field of grating cover technology, and in particular to an adjustable telescopic temporary steel grating cover. Background Technology

[0002] Temporary grating covers are a type of temporary protective facility widely used in construction, municipal maintenance, and underground pipeline maintenance. Their core structure typically consists of multiple steel grating units, connecting components, and supporting structures. Their main function is to cover openings, trenches, or equipment maintenance areas created during construction, preventing falls and debris from entering, while ensuring temporary passage or work safety in the construction area. These covers, thanks to the perforated structure of the steel grating, are lightweight, easy to transport, and offer good drainage. The "telescopic" design adapts to different sized coverage areas; the length or width is adjusted by the relative movement of the grating units. This represents a key research direction in the current field of temporary protective equipment, focusing on optimizing "scenario adaptability." In existing technologies, grating covers are typically fixed components, and are usually customized to the size of the trench opening. This results in insufficient multi-size telescopic adjustment capabilities, making it difficult to adjust the length according to the different trench lengths. The cover's adjustability is inadequate, its adaptability is poor, and staggered telescopic adjustments are inconvenient. Furthermore, the rigidity and load-bearing capacity of the grating cover are relatively insufficient, failing to adequately combine telescopic adjustment with high-strength rigidity. This lack of practicality and adaptability affects the cover's ability to freely adapt to different scenarios, limiting its widespread application in non-standard size protection scenarios. Therefore, we propose an adjustable-length telescopic temporary steel grating cover to solve these problems. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides an adjustable-length telescopic temporary steel grating cover to solve the problems mentioned above.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An adjustable-length telescopic steel grating temporary cover includes a load-bearing grating plate and an adjusting grating component, wherein transverse support plates are provided at equal intervals inside the load-bearing grating plate; Vertical insertion posts are provided at equal intervals on opposite sides of the two adjusting grid members. Support positioning holes are provided at equal intervals on the transverse support plate. The vertical insertion posts are inserted and positioned in the support positioning holes on the side away from the adjusting grid members. The vertical insertion posts are staggered and distributed in the bearing grid plate. The side of the vertical insertion post away from the adjusting grid members is threaded with a compression anti-detachment end, which fits and matches the support positioning hole.

[0005] Preferably, both sides of the load-bearing grid plate are provided with support partitions, and each of the two support partitions is provided with a load-bearing positioning hole. The multiple vertical insertion columns are respectively inserted and slid in the load-bearing positioning holes, and the vertical insertion columns are inserted and positioned on the support partitions by the load-bearing positioning holes.

[0006] Preferably, the extrusion anti-detachment end is provided with anti-detachment protrusions on both sides, the anti-detachment protrusions slide in the support positioning port, and the anti-detachment protrusions and the vertical insertion post fit and match.

[0007] Preferably, the load-bearing grating is rectangular in shape, and the two adjusting grating members are located on both sides of the load-bearing grating. Both adjusting grating members are telescopically connected to the load-bearing grating through vertical plug-in columns.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. This adjustable telescopic steel grating temporary cover plate features horizontal support plates evenly spaced inside the load-bearing grating plate. The adjustable grating components are inserted into the support positioning ports via vertical insertion columns, facilitating the splicing and combination of the adjustable grating components and the load-bearing grating plate. Pulling two adjustable grating components causes the vertical insertion columns to extend and retract within the load-bearing grating plate. This allows for easy adjustment of the two adjustable grating components according to the size of the trench. Furthermore, the staggered distribution of adjacent vertical insertion columns greatly improves the telescopic adjustment size, making the device easy to adjust according to the size of the trench and providing good adaptability.

[0013] 2. This adjustable-length telescopic steel grating temporary cover has anti-detachment ends at the ends of the vertical insertion columns. These ends prevent detachment during telescopic movement, ensuring stable positioning and preventing the vertical insertion columns from easily separating from the load-bearing grating plate. The telescopic adjustment is convenient, and the load-bearing grating plate is installed between two adjustable grating components, with staggered load-bearing structure, resulting in high load-bearing strength.
