Description

Technical Field

[0001] This utility model relates to the field of pipe gallery foundation pit technology, and in particular to a safety protection device for pipe gallery foundation pit. Background Technology

[0002] A utility tunnel excavation pit refers to the underground space excavated for the construction of an underground utility tunnel. A utility tunnel is a large-scale underground facility used for the centralized laying and maintenance of various municipal pipelines, such as electricity, communications, water supply, drainage, and gas, to improve the safety and efficiency of urban infrastructure. An excavation pit must be prepared before constructing such a facility.

[0003] The excavation of utility tunnel foundation pits typically involves complex geological conditions and technical challenges, especially in urban environments, where the safety of surrounding buildings and the impact of existing underground infrastructure must be considered. Therefore, a series of support measures are employed during excavation, such as diaphragm walls, pile-anchor systems, and soil nailing walls, to ensure slope stability and prevent groundwater seepage. After the foundation pit excavation is completed, the main structure of the utility tunnel will be constructed, followed by the installation of internal pipelines. The entire process requires rigorous quality control and safety monitoring to ensure project quality and the safety of the surrounding environment.

[0004] Existing support structures are mainly used for the support and fixation of individual utility tunnels. When supporting power lines in different sections, it is often necessary to design and construct new support structures separately. This approach not only significantly increases the cost of manpower and materials but also greatly extends the overall construction cycle. Because the support plan needs to be redesigned and implemented each time, it is not only time-consuming but also increases the complexity of the project and reduces construction efficiency. Utility Model Content

[0005] In order to overcome the shortcomings of existing support and protection devices that require replacement with suitable sizes to adapt to pipe gallery pits of different widths, the purpose of this utility model is to provide a pipe gallery pit safety protection device with adjustable width.

[0006] A safety protection device for a pipe gallery foundation pit includes a frame, sliding plates, fixed plates, fixed blocks, a two-way screw rod, a first connecting plate, sliding blocks, a fixing mechanism, and a locking mechanism. The left and right sides of the frame are open, and two sliding plates are slidably connected within the openings of the frame. Fixed plates are fixedly connected to the sides of the left and right sliding plates that are far apart from each other. Two fixed blocks are fixedly connected to the front of the frame, and a two-way screw rod is rotatably connected between the two fixed blocks. Both left and right sliding plates are threadedly connected to the two-way screw rod. Two first connecting plates are hinged to the left and right sides of the top of the frame. Two sliding blocks are slidably connected to the sides of the left and right fixed plates that are close to each other. The first connecting plates are hinged to the sliding blocks. Locking mechanisms and locking components are connected to the sides of the left and right fixed plates that are close to each other.

[0007] Furthermore, the locking mechanism includes a second connecting plate, a moving rod, and a connecting spring. Two second connecting plates are fixedly connected to the side of the left and right fixed plates that are close to each other, and at least one connecting spring is fixedly connected to the side of the front and rear second connecting plates that are far from each other. Two moving rods are slidably connected to the side of the left and right fixed plates that are close to each other, and the connecting spring is fixedly connected to the moving rod.

[0008] Furthermore, the locking assembly includes guide blocks and pressure plates. Guide blocks are fixedly connected to the sides of the left and right fixed plates that are close to each other, and pressure plates are slidably connected to the guide blocks.

[0009] Furthermore, it also includes a rotating plate, with the rotating plate hinged to the side of the left and right fixed plates that are far apart from each other.

[0010] Furthermore, it also includes a first locking block and a second locking block, with two first locking blocks fixedly connected to the front side of the frame and two second locking blocks fixedly connected to the rear side of the frame.

[0011] Furthermore, it also includes a sliding rod and a return spring. The sliding rod is slidably connected to the second locking block, and the return spring is fixedly connected between the sliding rod and the second locking block.

[0012] The beneficial effects of this utility model are as follows: By setting a sliding plate, a fixed plate, and a two-way screw rod, the fixed plate can be tightly attached to the inner wall of the pipe gallery pit by rotating the two-way screw rod, thus making it suitable for pipe gallery pits of different widths. Furthermore, the support strength of the fixed plate can be improved by the combined action of the locking mechanism and the locking assembly. A rotating plate is also provided, which can increase the height of the fixed plate, thus making it suitable for pipe gallery pits of different heights. Attached Figure Description

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0020] A safety protection device for pipe gallery foundation pit, such as Figures 1-5 As shown, the system includes a frame 1, a sliding plate 2, a fixed plate 3, a fixed block 4, a two-way screw 5, a first connecting plate 6, a sliding block 7, a fixing mechanism, and a locking mechanism. The left and right sides of the frame 1 are open. Two sliding plates 2 are slidably connected within the openings of the frame 1. Fixed plates 3 are fixedly connected to the sides of the left and right sliding plates 2 that are far apart from each other. Two fixed blocks 4 are fixedly connected to the front of the frame 1. A two-way screw 5 is rotatably connected between the two fixed blocks 4. The left and right sliding plates 2 are threadedly connected to the two-way screw 5. Two first connecting plates 6 are hinged to the top left and right sides of the frame 1. The two first connecting plates 6 are symmetrically arranged on the left and right sides. Two sliding blocks 7 are slidably connected to the sides of the left and right fixed plates 3 that are close to each other. The two sliding blocks 7 are symmetrically arranged on the left and right sides. The first connecting plates 6 are hinged to the sliding blocks 7. Locking mechanisms and locking components are connected to the sides of the left and right fixed plates 3 that are close to each other.

[0021] During the excavation of the utility tunnel foundation pit, this protective device is placed inside the pit. Then, the bidirectional screw 5 is manually rotated to make the sliding plate 2 slide away from each other along the frame 1, and the left and right fixed plates 3 move away from each other and are pressed against the inner wall of the utility tunnel foundation pit. During this process, the sliding blocks 7 slide downwards, causing the left and right first connecting plates 6 to rotate away from each other. With the cooperation of the locking mechanism and the fastening mechanism, the angle of the first connecting plate 6 is fixed. This allows the sliding distance of the sliding plate 2 to be adjusted according to the width of the utility tunnel foundation pit, so that the fixed plate 3 supports the inner wall of the utility tunnel foundation pit. This device is applicable to utility tunnel foundation pits of different widths, reduces the input cost of manpower and materials, shortens the overall construction cycle, and improves construction efficiency.

[0022] like Figure 1 , Figure 2 and Figure 4As shown, the locking mechanism includes a second connecting plate 8, a moving rod 9, and a connecting spring 10. Two second connecting plates 8 are fixedly connected to each other on the side of the left and right fixed plates 3 that are close to each other, and connecting springs 10 are fixedly connected to each other on the side of the front and rear second connecting plates 8 that are far apart from each other. The connecting springs 10 are set as helical springs. Two moving rods 9 are slidably connected to each other on the side of the left and right fixed plates 3 that are close to each other. Ten insert rods are provided on the moving rods 9. Slots adapted to the insert rods are opened on the sliding block 7. The ten insert rods can cooperate with the sliding displacement of the sliding block 7. The second connecting plate 8 and the moving rods are symmetrically arranged on the left and right. The connecting springs 10 are fixedly connected to the moving rods 9. The number of connecting springs 10 between the moving rods 9 and the second connecting plate 8 is two. The locking assembly includes a guide block 11 and a pressure plate 12. Guide blocks 11 are fixedly connected to each other on the side of the left and right fixed plates 3 that are close to each other. Pressure plates 12 are slidably connected to each guide block 11. When the pressure plate 12 moves downward to press the moving rod 9, the side of the pressure plate 12 that first contacts the moving rod 9 is an inclined surface.

[0023] Initially, the connecting spring 10 is in its normal position. The moving rod 9 is inserted into the sliding block 7, locking the first connecting plate 6. When the angle of the first connecting plate 6 needs to be adjusted, the front and rear second connecting plates 8 are brought closer together, compressing the connecting spring 10 and moving the moving rod 9 away from the slot of the sliding block 7. This unlocks the first connecting plate 6. After the angle of the first connecting plate 6 is adjusted, the second connecting plate 8 is released, and the connecting spring 10 returns to its original position, allowing the moving rod 9 to insert into the slot of the sliding block 7. The operation is simple and convenient, shortening the installation time of this protective device. After the locking mechanism locks the first connecting plate 6, the pressure plate 12 is moved downwards to be positioned between the front and rear second connecting plates 8. The pressure plate 12 moves downwards, pressing the front and rear second connecting plates 8, causing the front and rear moving rods 9 to move away from each other. The connecting spring 10 is stretched, thus maintaining the moving rod 9 inserted into the slot of the sliding block 7, preventing the moving rod 9 from loosening, and making the locking mechanism more secure.

[0024] like Figure 1 , Figure 3 and Figure 4 As shown, it also includes a rotating plate 13, with the left and right fixed plates 3 hinged to each other on their opposite sides to extend the height of the fixed plates 3. When the depth of the pipe gallery pit is greater than the height of the fixed plates 3, the rotating plate 13 is rotated to position itself on top of the fixed plates 3, and then the distance between the left and right fixed plates 3 is adjusted. This allows it to be used for pipe gallery pits of different heights, further increasing safety and improving construction efficiency.

[0025] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, it also includes a first locking block 14, a second locking block 15, a sliding rod 16, and a return spring 17. Two first locking blocks 14 are fixedly connected to the front side of the frame 1, and two second locking blocks 15 are fixedly connected to the rear side of the frame 1. The two first locking blocks 14 and the two second locking blocks 15 are arranged symmetrically from left to right. The first locking block 14 is provided with a protrusion, and the second locking block 15 is provided with a slot that matches the protrusion. The first locking block 14 can be locked into the slot of the second locking block 15 through the protrusion. The sliding rod 16 is slidably connected to the second locking block 15, and the return spring 17 is fixedly connected between the sliding rod 16 and the second locking block 15. The return spring 17 is set as a helical spring.

[0026] Because the length of frame 1 is limited, multiple protective devices need to be spliced ​​together to cover the entire pipe gallery pit. When the first locking block 14 is engaged in the second locking block 15, the left and right sliding rods 16 slide away from each other, the return spring 17 is compressed, the first locking block 14 is engaged in the slot of the second locking block 15, and then the left and right sliding rods 16 are released, the return spring 17 returns to its original state and the sliding rods 16 are reset, so that the first locking block 14 can be clamped and fixed in the slot. This allows adjacent frames 1 to be engaged and fixed together by the first locking block 14 and the second locking block 15, which facilitates the installation of the protective device in the pipe gallery pit and also improves the stability of the protective device.

[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
