Description

Technical Field

[0001] This application relates to the field of road construction technology, and more specifically, to a safety protection device for road construction pits. Background Technology

[0002] An excavation pit is a pit dug at the foundation design location according to the foundation elevation and foundation plane dimensions. Before excavation, the excavation plan should be determined based on geological and hydrological data and the conditions of nearby buildings, and waterproofing and drainage work should be carried out.

[0003] Currently, safety guardrails are needed to protect the foundation pits excavated for road construction. However, the existing safety guardrails used for foundation pits have a relatively simple structure and function, and cannot be adjusted to protect the foundation pit according to specific needs, thus reducing the overall practical effect of the safety guardrails.

[0004] To address the aforementioned problems, this application provides a safety protection device for road construction pits. Utility Model Content

[0005] The road construction pit safety protection device provided in this application adopts the following technical solution:

[0006] A road construction pit safety protection device includes two columns, which are horizontally spaced apart. Each column has a connecting plate in contact with the middle of its opposite end face. An adjustment component is provided between the middle of the two connecting plates, and a limit component is provided between the two sides of the two connecting plates. A locking component is provided at the connection point between the middle of each connecting plate and the outer surface of the column.

[0007] The adjustment assembly includes a threaded cylinder fixedly installed at the center of one end face of the left connecting plate. An adjusting screw is screwed to the inner wall of the threaded cylinder. One end of the adjusting screw is fixedly connected to a rotating shaft. The rotating shaft is located on the side of the threaded cylinder facing away from the connecting plate. A compensating rod is provided on the side of the rotating shaft facing away from the threaded cylinder. The compensating rod is fixedly installed at the center of one end face of the right connecting plate. A T-shaped groove is embedded in the center of the end face of the compensating rod facing the rotating shaft. A T-shaped shaft is rotatably sleeved on the inner wall of the T-shaped groove. One end of the T-shaped shaft extends out of the interior of the T-shaped groove and is fixedly connected to the center of one side of the rotating shaft.

[0008] The limiting component includes a limiting cylinder fixedly installed at the edge of one end face of the left connecting plate. A sliding rod is slidably connected through the center of one side of the limiting cylinder, and one end of the sliding rod is fixedly installed at the edge of one end face of the right connecting plate.

[0009] Through the above technical solution, the limiting component can not only limit the position adjustment of the two connecting plates, but also provide a horizontal safety protection function between the two connecting plates.

[0010] Furthermore, a rubber pad is fixedly fitted onto the outer wall of the rotating shaft, and multiple anti-slip grooves are evenly formed on the middle circumference of the outer wall of the rotating shaft.

[0011] The above technical solution facilitates manual screwing of the rotating shaft by using rubber pads and anti-slip grooves.

[0012] Furthermore, a limiting slide post is fixedly installed at one end of the slide rod facing away from the right-side connecting plate, and the limiting slide post is slidably sleeved on the inner wall of the limiting cylinder.

[0013] Through the above technical solution, the limiting slide column realizes the sliding limiting function between the limiting cylinder and the slide rod.

[0014] Furthermore, the locking assembly includes a through-hole formed on one side of the middle of the connecting plate. A screw is movably inserted into the inner wall of the connecting hole. The screw is fixedly installed on the outer surface of the column, and a locking nut is screwed onto the outer wall of one side of the screw. The locking nut is movably abutted against the end face of the connecting plate facing away from the column.

[0015] Through the above technical solution, the locking component enables the detachable positioning of the connecting plate and the column.

[0016] Furthermore, both columns are fixedly connected to a base plate at their bottom, and each base plate has multiple mounting holes evenly spaced around its perimeter.

[0017] The above technical solution allows the mounting holes on the chassis and its perimeter to facilitate the assembly and fixing of the columns at the required locations on the construction road.

[0018] Furthermore, both columns are prismatic hollow column structures, and a drainage hole is provided on one side of the bottom of the inner cavity of the two columns, with one end of the drainage hole extending to the outer surface of one side of the column.

[0019] In summary, this application includes the following beneficial technical effects:

[0020] This application, through the installation of two side columns and connecting plates, enables the threaded cylinder, adjusting screw, rotating shaft, compensating rod, T-slot, T-shaft, limiting cylinder, and sliding rod installed in the positions between them to be assembled on-site at the road construction pit and to effectively protect the pit. At the same time, the length of the protective effect on the pit can be adjusted according to the specific needs of the site, thereby effectively improving the practical effect of the overall safety guardrail.

[0030] Example:

[0031] This application discloses a safety protection device for road construction pits. Please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 and Figure 4 It includes two columns 1, which are horizontally spaced apart. Each column 1 has a connecting plate 2 in contact with the middle of its opposite end face. An adjustment component is provided between the middle of the two connecting plates 2, and a limit component is provided between the two sides of the two connecting plates 2. A locking component is provided at the connection point between the middle of each connecting plate 2 and the outer surface of the column 1.

[0032] The adjustment assembly includes a threaded cylinder 3 fixedly installed at the center of one end face of the left connecting plate 2. An adjusting screw 4 is screwed to the inner wall of the threaded cylinder 3. One end of the adjusting screw 4 is fixedly connected to a rotating shaft 5. The rotating shaft 5 is located on the side of the threaded cylinder 3 facing away from the connecting plate 2. A compensating rod 6 is provided on the side of the rotating shaft 5 facing away from the threaded cylinder 3. The compensating rod 6 is fixedly installed at the center of one end face of the right connecting plate 2. A T-shaped groove 7 is embedded in the center of the end face of the compensating rod 6 facing the rotating shaft 5. A T-shaped shaft 8 is rotatably sleeved on the inner wall of the T-shaped groove 7. One end of the T-shaped shaft 8 extends out of the interior of the T-shaped groove 7 and is fixedly connected to the center of one side of the rotating shaft 5. A rubber gasket is fixedly sleeved on the outer wall of the rotating shaft 5. Multiple anti-slip grooves are evenly formed on the middle circumference of the outer wall of the rotating shaft 5.

[0033] The limiting component includes a limiting cylinder 9 fixedly installed at the edge of one end face of the left connecting plate 2. A sliding rod 10 is slidably connected through the center of one side of the limiting cylinder 9. One end of the sliding rod 10 is fixedly installed at the edge of one end face of the right connecting plate 2. A limiting sliding post is fixedly installed at the end of the sliding rod 10 facing away from the right connecting plate 2. The limiting sliding post is slidably sleeved on the inner wall of the limiting cylinder 9. The limiting sliding post realizes the sliding limitation between the limiting cylinder 9 and the sliding rod 10, while preventing the two from slipping off.

[0034] The locking assembly includes a through hole 11 located on one side of the middle of the connecting plate 2. A screw 12 is movably inserted into the inner wall of the through hole 11. The screw 12 is fixedly installed on the outer surface of the column 1, and a locking nut 13 is screwed onto the outer wall of one side of the screw 12. The locking nut 13 is movably abutted against the end face of the connecting plate 2 facing away from the column 1.

[0035] Both upright posts 1 are fixedly connected to a base plate 14 at their bottoms. Each base plate 14 has multiple mounting holes evenly spaced around its perimeter. Both upright posts 1 are prismatic hollow column structures, and a drainage hole 15 is provided on one side of the bottom of the inner cavity of each upright post 1. One end of the drainage hole 15 extends to the outer surface of one side of the upright post 1. The hollow structure design of the upright post 1 can ensure its own hardness coefficient while effectively reducing its own weight, thereby facilitating the movement and handling of the entire safety guardrail. The drainage hole 15 provided on one side of the bottom of the inner cavity of the upright post 1 can drain the rainwater accumulated in the inner cavity of the upright post 1 during use.

[0036] The implementation principle of this embodiment is as follows: When in use, the distance between the two connecting plates 2 can be adjusted according to the required safety protection length at the foundation pit site. During adjustment, it is only necessary to manually turn the rotating shaft 5. The T-shaped groove 7 and T-shaped shaft 8 between the rotating shaft 5 and the compensation rod 6 are in a limited rotational fit, and the adjusting screw 4 at one end of the rotating shaft 5 is in a screwed state with the inner wall of the threaded cylinder 3. This causes the screwed position of the threaded cylinder 3 and the adjusting screw 4 to change, thereby indirectly realizing the adjustment of the distance between the two connecting plates 2. During this process, each limiting cylinder 9 and the sliding rod 10 perform a limited linear sliding fit movement.

[0037] Then, while the two connecting plates 2 are respectively connected to the two columns 1, each screw 12 is inserted into each docking hole 11. Then, each locking nut 13 is assembled on one side of the screw 12, thereby realizing the assembly and locking work between each column 1 and the connecting plate 2. Finally, through each chassis 14 and its surrounding mounting holes, the whole assembly is fixed in the required position of the road construction pit, and the length of the safety protection function of the pit can be adjusted according to specific needs.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
