Description

Technical Field

[0001] This utility model belongs to the field of road construction protection technology, specifically, it relates to a road foundation pit safety protection device. Background Technology

[0002] To prevent soil erosion, collapse, and other safety issues during foundation pit excavation, and to ensure the safety of construction workers and the smooth progress of construction, foundation pit protection equipment is used. When there are important buildings, underground pipelines, or major roads around the construction area, foundation pit excavation may affect the surrounding environment. In this case, foundation pit safety protection equipment can also reduce the interference with the surrounding environment and ensure the safety and stability of construction.

[0003] The prior art discloses a safety protection device for municipal road foundation pits (CN221703372U), which relates to the field of protection device technology. It includes a guardrail bracket, with a lower connecting plate fixedly connected to one side of the guardrail bracket. A rotating block is rotatably connected to the middle of the lower connecting plate. The advantages of this invention are: the partition plate is flipped to one side of the foundation pit by the rotating block, and then the first and second support rods are pushed and fixed by nuts. The first and second support rods are connected to the upper connecting plate by a connecting block at one end, and to the partition plate by a limiting rod inside the slider at the other end, thus forming a triangular connection support for the guardrail to reduce the risk of tipping over and improve the stability of the guardrail. Inclined partition plates are fixedly installed on the inner sides of the upper and lower connecting plates. The inclined partition plates are all set at an angle to the upper and lower connecting plates, which can reduce the impact of wind on the inclined partition plates and improve their stability.

[0004] The search revealed that existing technologies use support rods and partitions for support, which takes up too much space. The presence of support rods also poses certain safety hazards to workers, who are prone to tripping during construction, which is not conducive to the construction work. Furthermore, the use of existing technologies is not convenient for storing and organizing the device, and it is easy to occupy too much public space.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content

[0006] To address the aforementioned technical problems that pose safety hazards, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A road foundation pit safety protection device, including

[0008] A base plate is fixedly placed on the ground, and a support frame is rotatably provided on the top surface of the base plate;

[0009] A control assembly is movably disposed between the base plate and the support frame. The control assembly includes an arc plate, a linkage seat, a stop block, a rotating rod, and a ratchet disc. The arc plate is fixedly disposed within the support frame, the linkage seat is fixedly disposed on the bottom surface of the support frame, the stop block is movably disposed within the support frame, the rotating rod is rotatably disposed above the base plate, and the ratchet disc is threaded onto one end of the rotating rod.

[0010] In a preferred embodiment of this utility model, the base plate is a square plate, a slot is provided on one side of the base plate, and a clip is fixedly connected to the other side of the base plate, the clip being engaged in the slot.

[0011] In a preferred embodiment of this utility model, the support frame is a square frame, a fixing groove is provided on one side of the support frame, and a card plate is fixedly connected to the other side of the support frame. The card plate is correspondingly engaged in the fixing groove, and the fixing groove and the card plate are limited by a stop block.

[0012] In a preferred embodiment of this utility model, an I-shaped movable groove is provided on one side of the fixed groove, and a latch is provided on one side of the clamping plate. The latch corresponds to the movable groove, and an I-shaped blocking block is slidably connected in the movable groove. A spring is fixedly provided between the blocking block and the movable groove. The blocking block is elastically connected to the fixed groove through the spring, and the blocking block is latched in the latch.

[0013] In a preferred embodiment of this utility model, two linkage seats are symmetrically fixed on the bottom surface of the support frame, and two support seats and one support are fixedly connected to the top surface of the base plate. The two support seats are symmetrically arranged with the support as the center. A fixing rod is fixedly arranged between the two support seats and the support. The linkage seats are rotatably connected to the curved surfaces at both ends of the fixing rod. A rotating rod is rotatably arranged between the two support seats and the support. A ratchet disk is slidably arranged inside the support seat.

[0014] In a preferred embodiment of this utility model, the support base is composed of two symmetrically arranged arc-shaped plates. An inner groove is formed in the arc-shaped plate, and a ratchet disk is slidably connected in the inner groove. A ratchet tooth is fixedly provided on each side of the linkage base, and the ratchet tooth meshes with the ratchet disk.

[0015] In a preferred embodiment of this utility model, a positive and negative threaded rod is fixedly connected to each end of the rotating rod, and a ratchet disc is threaded into each end of the positive and negative threaded rod. A handle is fixedly connected to the middle of the rotating rod, and a movable opening is provided inside the support. The two support seats and the same rotating rod are rotatably connected to the support. The handle is rotatably disposed in the movable opening.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. By setting up control components, rotating the handle controls the rotation of the lever, causing the ratchet discs at both ends to move away from both sides of the linkage seat simultaneously. This controls the angle between the support frame and the base plate in real time. When the support frame and the arc plate contact the inner surface of the pit to form protection, rotating the lever uses the ratchet discs to clamp and fix the position of the support frame in the linkage seat. This not only achieves a stable fixing effect but also avoids safety hazards caused by external factors, thus making it more conducive to the construction work of workers.

[0018] 2. By setting up overlapping base plates and support frames, the angle between the two can be fixed using the principle of ratchet braking. When not in use, turning the lever and moving the ratchet disk away from the linkage seat will allow the base plate and support frame to overlap, making it easy to store and thus avoiding taking up too much public space.

[0019] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0028] A road foundation pit safety protection device, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the system includes a base plate 10, which is fixedly placed on the ground. A support frame 11 is rotatably mounted on the top surface of the base plate 10. A control assembly is movably mounted between the base plate 10 and the support frame 11. The control assembly includes an arc plate 12, a linkage seat 20, a stop block 22, a rotating rod 29, and a ratchet disc 30. The arc plate 12 is fixedly mounted inside the support frame 11. The linkage seat 20 is fixedly mounted on the bottom surface of the support frame 11. The stop block 22 is movably mounted inside the support frame 11. The rotating rod 29 is rotatably mounted above the base plate 10. The ratchet disc 30 is threaded onto one end of the rotating rod 29.

[0029] Specifically, this device, through the setting of control components, rotates the lever 29 to move the ratchet discs 30 at both ends away from the sides of the linkage seat 20, thereby controlling the angle between the support frame 11 and the base plate 10 in real time. When the support frame 11 and the arc plate 12 contact the inner surface of the foundation pit to form protection, rotating the lever 29 causes the ratchet discs 30 to converge and clamp the linkage seat 20, thereby fixing the position of the support frame 11. This not only achieves a stable fixing effect but also avoids safety hazards caused by external factors, thus making it more conducive to the construction of workers. When the ratchet discs 30 at both ends move away from the sides of the linkage seat 20, the base plate 10 and the support frame 11 can overlap, allowing them to use the ratchet braking principle to fix the angle, while also facilitating storage and avoiding occupying too much public space.

[0030] like Figure 1 and Figure 2 As shown, the base plate 10 is a square plate. A slot 14 is provided on one side of the base plate 10, and a retaining strip 18 is fixedly connected to the other side of the base plate 10. The retaining strip 18 is correspondingly engaged within the slot 14. Figure 1 and Figure 2 As shown, the support frame 11 is a square frame. A fixing groove 13 is provided on one side of the support frame 11, and a retaining plate 17 is fixedly connected to the other side of the support frame 11. The retaining plate 17 is correspondingly engaged within the fixing groove 13, and the fixing groove 13 and the retaining plate 17 are limited by a stop block 22. Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an I-shaped movable groove 21 is provided on one side of the fixed groove 13, and a slot 28 is provided on one side of the clamping plate 17. The slot 28 corresponds to the movable groove 21. An I-shaped blocking block 22 is slidably connected in the movable groove 21. A spring 27 is fixedly provided between the blocking block 22 and the movable groove 21. The blocking block 22 is elastically connected to the fixed groove 13 through the spring 27, and the blocking block 22 is engaged in the slot 28.

[0031] The working principle is as follows: Considering the different areas of the foundation pit, this device can be assembled and used together. When in use, the locking strip is aligned with the locking slot 14, and the locking plate 17 is aligned with the fixing slot 13, and the two devices are locked together. During this process, the blocking block 22 needs to be pulled up in advance. With the help of the spring 27, the blocking block 22 is pulled back into the movable slot 21. It should be noted that the length of the blocking block 22 is longer than the movable slot 21. At the same time, the side of the blocking block 22 near the outside is provided with a finger groove for easy pulling, so that workers can easily pinch the blocking block 22. After the locking plate 17 of the other device is locked into the fixing slot 13 of one of the devices, the blocking block 22 is released. The blocking block 22 is locked into the locking slot 28 of the other device by the rebound of the spring 27, thereby fixing the two devices.

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, two linkage seats 20 are symmetrically fixed to the bottom surface of the support frame 11, and two support seats 15 and one support 19 are fixedly connected to the top surface of the base plate 10. The two support seats 15 are symmetrically arranged with the support 19 as the center. A fixing rod 26 is fixedly arranged between the two support seats 15 and the support 19. The linkage seats 20 are rotatably connected to the curved surfaces at both ends of the fixing rod 26. A rotating rod 29 is rotatably arranged between the two support seats 15 and the support 19. A ratchet disk 30 is slidably arranged inside the support seat 15. Figure 3 and Figure 5 As shown, the support base 15 consists of two symmetrically arranged arc-shaped plates. An inner groove 24 is formed within the arc-shaped plate, and a ratchet disc 30 is slidably connected within the inner groove 24. A ratchet tooth 23 is fixedly installed on each side of the linkage base 20, and the ratchet tooth 23 meshes with the ratchet disc 30. Figure 3 and Figure 5 As shown, a positive and negative threaded rod 31 is fixedly connected to each end of the rotating rod 29. A ratchet disc 30 is threaded into each end of the positive and negative threaded rod 31. A handle 32 is fixedly connected to the middle of the rotating rod 29. An movable opening 25 is opened inside the support 19. The two support seats 15 and the support 19 are rotatably connected to the same rotating rod 29. The handle 32 is rotatably set in the movable opening 25.

[0033] Specifically, in the initial state, the ratchet disc 30 is away from the ratchet teeth 23 on both sides of the linkage seat 20. At this time, the support frame 11 can rotate around the fixed rod 26 within the support seat 15 with the help of the linkage seat 20, or it can be overlapped with the base plate 10 for storage. In use, the support frame 11 is moved to control the angle between the support frame 11 and the base plate 10. After the angle is appropriate, the handle 32 is turned. The handle 32 controls the rotation of the rotating rod 29. At this time, the positive and negative threaded rods 31 located at both ends of the rotating rod 29 rotate accordingly. Taking one end of the rotating rod 29 as an example, at this time, the two symmetrically arranged ratchet discs 30 on the positive and negative threaded rods 31 at one end converge and slide in the corresponding inner grooves 24. When the ratchet disc 30 contacts the corresponding linkage seat 20, the ratchet disc 30 brakes the corresponding ratchet teeth 23. Specifically, the ratchet teeth 23 on both sides of the linkage seat 20 are in different directions. When the two ratchet discs 30 clamp at the same time, the position of the linkage seat 20 is controlled and cannot rotate. At this time, the device achieves a protective function.
