Description

Technical Field

[0001] The invention relates to the technical field of municipal construction, and in particular to a foundation pit safety protection device for municipal roads. Background Art

[0002] Municipal road construction usually requires excavation of foundation pits, which are earth pits excavated at the foundation design location according to the base 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 should be done. If the excavation is not deep, the side slope can be used to stabilize the soil slope, and the slope size is determined according to relevant construction regulations.

[0003] Since the foundation pit is lower than the normal road, it is difficult for workers inside the foundation pit to confirm the external status, and it is also difficult to notice the external conditions while working. Therefore, in order to ensure the safety inside the foundation pit, fences are usually set up around the foundation pit to surround the foundation pit. However, when the fence is collided, the fence will fall into the foundation pit, posing a danger to the people in the foundation pit. Summary of the invention

[0004] In order to solve the problem that when the enclosure is hit in the prior art, the enclosure will fall into the foundation pit, posing a danger to the personnel in the foundation pit, the present application provides a municipal road foundation pit safety protection device, the specific scheme is A foundation pit safety protection device for a municipal road comprises a top plate and a bottom plate, wherein the bottom plate is used to be fixed to the ground, the top plate is arranged parallel to the bottom plate, an upper protection plate is arranged on the top plate, a top ball of the upper protection plate is hinged on the top plate, a plurality of upper protection plates are arranged along the length direction of the top plate, and a lower protection plate is arranged on the bottom plate, a plurality of lower protection plates are arranged along the length direction of the bottom plate and are arranged one-to-one with the upper protection plates, a bottom ball of the lower protection plate is hinged on the bottom plate, and a gap is left between the upper protection plate and the lower protection plate; A rubber connecting rod is arranged between the upper protective plate and the lower protective plate, one end of the rubber connecting rod is detachably connected to the upper protective plate, and the other end of the rubber connecting rod is detachably connected to the corresponding lower protective plate. The rubber connecting rod has a tendency to pull the upper protective plate and the lower protective plate closer to each other, and the rubber connecting rod can recover after deformation.

[0005] By adopting the above technical solution, the upper protective plate and the lower protective plate are installed through the top plate and the bottom plate. The guardrail as a whole can still surround the foundation pit and play a safety protection role. The upper protective plate and the lower protective plate can buffer the impact by swinging when hit, reducing the guardrail from tipping over due to the impact. It can also buffer the impact force and reduce the situation where pedestrians accidentally hit the guardrail and get injured.

[0006] Optionally, an elastic protective member is further provided between the upper protective plate and the lower protective plate, the upper side of the elastic protective member is detachably connected to the upper protective plate, and the lower side of the elastic protective member is detachably connected to the lower protective plate. The elastic protective member is provided along the gap between the upper protective plate and the lower protective plate, and the elastic protective member is used to cover the gap between the upper protective plate and the lower protective plate. The elastic protective member has a tendency to pull the upper protective plate and the lower protective plate closer to each other.

[0007] By adopting the above technical solution and setting up elastic protective parts, the upper protective plate and the lower protective plate can be further buffered, thereby improving the buffering effect of impact force. At the same time, the elastic protective parts can protect pedestrians from being squeezed between the lower protective plate and the upper protective plate, thereby further improving safety.

[0008] Optionally, the upper protective plate and the lower protective plate are provided with hanging hooks, and the elastic protective member is provided with hanging holes corresponding to the hanging hooks, and the hanging holes are used for hanging on the hanging hooks.

[0009] By adopting the above technical solution, the hooks provided on the upper and lower protective plates and the hook holes on the elastic protective member make it easy and quick to install and remove the elastic protective member, thus improving the installation efficiency. At the same time, the coordinated use of the hook holes and hooks ensures the stability and reliability of the elastic protective member during use, effectively preventing the risk of the elastic protective member falling off, and enhancing the overall safety of the foundation pit safety protection device.

[0010] Optionally, an inclined support plate is further provided between the top plate and the bottom plate, the inclined support plate is inclined, the upper side of the inclined support plate is fixedly connected to the top plate, the lower side of the inclined support plate is fixedly connected to the bottom plate, and the distance between the top of the inclined support plate and the upper protective plate is greater than the distance between the bottom of the inclined support plate and the lower protective plate.

[0011] By adopting the above technical solution and setting an inclined support plate, the inclined support plate can change the force direction when impacted, making the guardrail as a whole less likely to topple over, thereby reducing the situation where the guardrail topples over and causes injuries to people in the foundation pit.

[0012] Optionally, a support rod is provided at the lower part of the oblique support plate corresponding to the lower protective plate, and the side of the support rod close to the oblique support plate is hinged to the oblique support plate, and the side of the support rod away from the oblique support plate is provided with a rubber ball, and the rubber ball is used to abut the lower protective plate. When the support rod is rotated to the extreme position, it is perpendicular to the oblique support plate or parallel to the oblique support plate.

[0013] By adopting the above technical scheme, the support rod can support the lower protective plate. When the elastic protective part is not installed, the lower protective plate will be abutted by the support rod, reducing the possibility of the lower protective plate tipping over due to lack of support. During installation, there is no need to erect each lower protective plate one by one, thereby improving the convenience of installation. At the same time, the rubber ball on the support rod can further support the lower protective plate. Due to the action of gravity during collision, the lower protective plate is subjected to a greater force. Therefore, adding a support rod can further improve the supporting effect.

[0014] Optionally, a torsion spring is provided at the hinge of the support rod, and the torsion spring has a tendency to push the support rod to move toward the lower protective plate.

[0015] By adopting the above technical solution, the provision of a torsion spring can further improve the abutment effect on the lower protective plate, thereby further improving the buffering protection effect at the lower protective plate.

[0016] Optionally, a positioning rod is further provided on the oblique support plate, and the lower end of the positioning rod can abut against the bottom plate.

[0017] By adopting the above technical solution, setting the positioning rod can provide support for the oblique support plate, reduce damage to the oblique support plate when it is impacted, improve the support effect, and further increase the service life.

[0018] Optionally, the upper end of the positioning rod is slidably connected to the oblique support plate and slides along the inclination direction of the oblique support plate, and the lower end of the positioning rod is provided with a telescopic rod capable of adjusting the length, the telescopic rod can abut the bottom plate, and the telescopic rod can also extend out of the bottom plate.

[0019] By adopting the above technical solution, an extendable telescopic rod is provided, and the positioning rod can be moved. After the positioning rod is moved out of the position of the bottom plate, the telescopic rod can be extended and overlapped on the pit wall of the foundation pit. When the guardrail is pushed, the telescopic rod can interfere with the pit wall of the foundation pit, thereby further reducing the situation where the guardrail tilts and falls when being pushed.

[0020] In summary, this application has at least the following beneficial effects: 1. The present application solves the problem in the prior art that when the lower enclosure is hit, the enclosure will topple into the foundation pit, posing a danger to the personnel in the foundation pit. The present application provides a ball-hinged upper protective plate and a lower protective plate. When the guardrail is hit, the upper protective plate and the lower protective plate can cushion the impact, which can reduce the guardrail from toppling due to the impact and reduce the injury to pedestrians who collide with the guardrail.

[0021] 2. The present application also further increases the buffering effect by providing elastic protective parts, and can also further reduce the situation where the upper protective plate and the lower protective plate squeeze pedestrians and cause injuries to pedestrians, thereby further improving safety.

[0022] 3. The present application also provides a positioning rod and a telescopic rod, and the telescopic rod is in contact with the pit wall of the foundation pit. When the guardrail is collided, the telescopic rod is impacted and a reaction force is formed with the foundation pit, thereby further reducing the guardrail from tipping over when impacted and further improving safety.

[0028] The present application is further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0029] Embodiment 1 A municipal road foundation pit safety protection device, such as Figure 1 and Figure 2 As shown, it includes a top plate 1 and a bottom plate 2, the bottom plate 2 is used to be fixed to the ground, and the top plate 1 is arranged parallel to the bottom plate 2. In specific implementation, the bottom plate 2 can be fixed to the ground by ground nails to reduce the possibility of tipping. In other embodiments, a light group can be set on the top plate 1, and the light group can be lit during construction at night to serve as a reminder to pedestrians and vehicles, further improving safety.

[0030] like Figure 1 and Figure 3As shown, an upper protective plate 11 is provided on the top plate 1, and the top ball of the upper protective plate 11 is hinged on the top plate 1. A plurality of upper protective plates 11 are provided along the length direction of the top plate 1, and a lower protective plate 21 is provided on the bottom plate 2. A plurality of lower protective plates 21 are provided along the length direction of the bottom plate 2 and are arranged one-to-one with the upper protective plate 11. The bottom ball of the lower protective plate 21 is hinged on the bottom plate 2, and a gap is left between the upper protective plate 11 and the lower protective plate 21. A rubber connecting rod 111 is provided between the upper protective plate 11 and the lower protective plate 21, and one end of the rubber connecting rod 111 is detachably connected to the upper protective plate 11, and the other end of the rubber connecting rod 111 is detachably connected to the corresponding lower protective plate 21. The rubber connecting rod 111 has a tendency to pull the upper protective plate 11 and the lower protective plate 21 closer to each other, and the rubber connecting rod 111 can be restored after deformation. During specific implementation, the upper protective plate 11 can pull up the lower protective plate 21 through the rubber connecting rod 111. When impacted, the upper protective plate 11 and the lower protective plate 21 can be pushed and moved. At the same time, the rubber connecting rod 111 is deformed to form a corresponding shape according to the impact, thereby buffering the impact and reducing the possibility of the guardrail tipping over due to impact.

[0031] like Figure 3 As shown, an elastic protective member 3 is also provided between the upper protective plate 11 and the lower protective plate 21. The upper side of the elastic protective member 3 is detachably connected to the upper protective plate 11, and the lower side of the elastic protective member 3 is detachably connected to the lower protective plate 21. The elastic protective member 3 is provided along the gap between the upper protective plate 11 and the lower protective plate 21. The elastic protective member 3 is used to block the gap between the upper protective plate 11 and the lower protective plate 21. The elastic protective member 3 has a tendency to pull the upper protective plate 11 and the lower protective plate 21 closer to each other. In specific implementation, the elastic protective member 3 may include a cut rubber segment, or may include an elastic material such as nylon, which can further improve the buffering effect when impacted. At the same time, this material can also buffer the impact on pedestrians, further improve the protection effect on pedestrians, and reduce the injury of pedestrians. In other embodiments, a striking reminder sign, such as a sign coated with fluorescent powder, can also be provided on the elastic protective member 3 to remind pedestrians and vehicles not to approach.

[0032] like Figure 3 As shown, the upper protective plate 11 and the lower protective plate 21 are provided with a hook 22, and the elastic protective member 3 is provided with a hook hole 31 corresponding to the hook 22, and the hook hole 31 is used to be hung on the hook 22. In specific implementation, the hook 22 can be made of elastic material to further reduce the situation of injury caused by collision. Each upper protective plate 11 and the lower protective plate 21 are provided with two hooks 22, wherein the hook 22 of the upper protective plate 11 is bent upward, and the hook 22 of the lower protective plate 21 is bent downward, and after installation, they can play a role in fixing the elastic protective member 3, reducing the situation of the elastic protective member 3 falling off from the hook 22.

[0033] like Figure 3 As shown, an oblique support plate 4 is further arranged between the top plate 1 and the bottom plate 2. The oblique support plate 4 is arranged obliquely, the upper side of the oblique support plate 4 is fixedly connected to the top plate 1, and the lower side of the oblique support plate 4 is fixedly connected to the bottom plate 2. The distance between the top of the oblique support plate 4 and the upper protective plate 11 is greater than the distance between the bottom of the oblique support plate 4 and the lower protective plate 21. In specific implementation, the oblique support plate 4 can form a Z-shape for the guardrail as a whole. When installing, the upper protective plate 11 and the lower protective plate 21 need to be arranged on the outer side. When the guardrail is impacted, the impact force will first impact the upper protective plate 11 and the lower protective plate 21, and then the oblique support plate 4 will bear the impact. The oblique support plate 4 can convert part of the impact force into a downward impact force, thereby reducing the tilting of the oblique support plate 4 due to the impact, and further improving the stability.

[0034] like Figure 3 As shown, a support rod 41 is provided at the lower part of the oblique support plate 4 corresponding to the lower protective plate 21. The side of the support rod 41 close to the oblique support plate 4 is hinged to the oblique support plate 4, and the side of the support rod 41 away from the oblique support plate 4 is provided with a rubber ball 411, and the rubber ball 411 is fixedly connected to the support rod 41. The rubber ball 411 is used to abut the lower protective plate 21. When the support rod 41 rotates to the extreme position, it is perpendicular to the oblique support plate 4 or parallel to the oblique support plate 4. In specific implementation, the rubber ball 411 can increase the friction force against the lower protective plate 21, thereby supporting the lower protective plate 21. When impacted, the rubber ball 411 can rebound to further improve the buffering effect. When the impact force is large, the support rod 41 can rotate upward to reduce damage and increase the service life.

[0035] like Figure 3 As shown, a torsion spring is provided at the hinge of the support rod 41, and the torsion spring has a tendency to push the support rod 41 to move toward the lower protective plate 21. In specific implementation, the torsion spring will continuously push the lower protective plate 21 back to its original position in normal state, that is, both are in a vertical position with the upper protective plate 11. When impacted, the support rod 41 can improve the buffering effect, and when no force is applied, the support rod 41 can assist the lower protective plate 21 to reset.

[0036] Working principle: During installation, the side with the upper protective plate 11 and the lower protective plate 21 is set toward the side away from the foundation pit, and then the elastic protective member 3 is installed between the upper protective plate 11 and the lower protective plate 21. After the installation is completed, the guardrail can play a role in blocking collision. When impacted, the upper protective plate 11 and the lower protective plate 21 can buffer the impact force and reduce the possibility of tipping over.

[0037] Embodiment 2 like Figure 4As shown, the oblique support plate 4 is also provided with a positioning rod 42, the upper end of the positioning rod 42 is slidably connected with the oblique support plate 4 and slides along the oblique direction of the oblique support plate 4, and the lower end of the positioning rod 42 can abut the bottom plate 2. The lower end of the positioning rod 42 is provided with a telescopic rod 421 that can adjust the length, and the telescopic rod 421 can abut the bottom plate 2, and the telescopic rod 421 can also extend out of the bottom plate 2. In specific implementation, the telescopic rod 421 can abut the bottom plate 2 directly in the guardrail to support the oblique support plate 4, and can also slide the positioning rod 42 when installed near the foundation pit, and after the telescopic rod 421 is extended, it abuts against the pit wall of the foundation pit to form interference, so as to interfere with the pit wall when impacted to reduce the situation of tipping.

[0038] Working principle: The basic working principle is the same as that of embodiment 1, but this embodiment adds a positioning rod 42. The positioning rod 42 can both abut the oblique support plate 4 and pull out the bottom plate 2, thereby interfering with the pit wall of the foundation pit. When the guardrail as a whole is impacted, the telescopic rod 421 can just have a reaction force under the action of the foundation pit, further reducing the possibility of the guardrail tipping over due to impact.

[0039] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
