Description

Technical Field

[0001] This utility model relates to the field of pre-embedded device technology, and in particular to a pre-embedded frame for municipal underground pipeline networks. Background Technology

[0002] Municipal underground pipe networks are a vital infrastructure for urban operations, encompassing various pipelines such as water supply, drainage, gas, heating, electricity, and communications. These pipelines are typically pre-buried underground and arranged through centralized pipe spaces (i.e., pipe galleries). The use of pre-buried devices can significantly reduce the difficulty of pipeline installation and provide protection for the pipelines.

[0003] Existing municipal underground pipeline pre-embedded devices use the cooperation of plugs and slots to splice multiple devices, relying on foundation fixation to maintain stability. However, the hollow design under the protective plate makes it prone to irreversible deformation under excessive pressure, resulting in low structural strength. The protective frame relies solely on the foundation for fixation; when the foundation loosens, the movement of a single protective frame can reduce the connection effect of the plugs, thus affecting the overall stability. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a municipal underground pipeline pre-embedded frame, which aims to improve the problem of low structural strength and easy deformation under pressure of the protective plate of the pre-embedded device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a municipal underground pipeline pre-embedded frame, comprising a horizontal support frame, a first longitudinal support frame fixedly connected to the front outer wall of the horizontal support frame, a second longitudinal support frame fixedly connected to the rear side of the horizontal support frame, a protective plate rotatably connected to the top of the second longitudinal support frame, two fixing bolts slidably connected to the inner wall of the protective plate, multiple pipe support frames slidably connected to the top of the horizontal support frame, pipelines slidably connected to the top of the pipe support frames, multiple reinforcing plates slidably connected to the top of the pipelines, multiple pre-embedded bolts slidably connected to the inner wall of the horizontal support frame, nuts threadedly connected to the top of the pre-embedded bolts, and a lifting assembly provided on the right side of the first longitudinal support frame.

[0006] The above technical solution involves fixing the protective plate with fixing bolts, thereby securing the reinforcing plate within the support frame. This allows the pipeline to be supported by the pipeline support frame and the reinforcing plate to be fixed within the support frame.

[0007] As a further description of the above technical solution:

[0008] Preferably, the lifting assembly includes a fixed frame, which is fixedly connected to the outer wall of the first longitudinal support frame. A gear is rotatably connected to the inner wall of the fixed frame. Two racks are meshed at the ends of the gears. A first movable frame is fixedly connected to the left side of one rack, and a second movable frame is fixedly connected to the right side of the other rack.

[0009] Through the above technical solution, the first movable frame and the rack on the left, and the second movable frame and the pipe support frame on the right, slide together in the fixed frame through gears, which can form a lifting structure to push the protective plate.

[0010] As a further description of the above technical solution:

[0011] Preferably, the outer wall of the transverse support frame is slidably connected to a connecting block, the connecting block is slidably connected to the outer wall of a pre-embedded bolt, the pre-embedded bolt is fixedly connected to the concrete, and the nut is slidably connected to the outer wall of the connecting block and the outer wall of the transverse support frame.

[0012] Through the above technical solution, the pre-embedded bolts and nuts can fix multiple support frames through the connecting blocks, and at the same time, the pre-embedded bolts can fix the support frames to the foundation, which can enhance stability.

[0013] As a further description of the above technical solution:

[0014] Preferably, the reinforcing plate is slidably connected to the outer wall of the first longitudinal support frame, and the reinforcing plate is slidably connected to the outer wall of the second longitudinal support frame.

[0015] Through the above technical solution, the reinforcing plate can slide vertically on the reinforcing ribs of the transverse support frame through the reinforcing ribs of the first longitudinal support frame and the second longitudinal support frame.

[0016] As a further description of the above technical solution:

[0017] Preferably, the reinforcing plate is slidably connected to the top of the transverse support frame, the reinforcing plate is slidably connected to the bottom of the protective plate, and the fixing bolt passes through the protective plate and is threadedly connected to the first longitudinal support frame.

[0018] The above technical solution involves multiple reinforcing plates sliding on the top of the transverse support frame, which can support the first longitudinal support frame and the second longitudinal support frame, thereby enhancing the strength of the support frame.

[0019] As a further description of the above technical solution:

[0020] Preferably, the top of the reinforcing plate is provided with a rectangular groove, and the pipe support frame is slidably connected to the outer wall of the reinforcing plate.

[0021] With the above technical solution, during installation, the rectangular groove allows workers to hold the top of the reinforcing plate, facilitating its movement. When disassembling the reinforcing plate, it can also be easily pulled out.

[0022] As a further description of the above technical solution:

[0023] Preferably, the first movable frame is slidably connected to the inner wall of the fixed frame, the second movable frame is slidably connected to the outer wall of the fixed frame, the first movable frame is slidably connected to the inner wall of the first longitudinal support frame, and the second movable frame is slidably connected to the outer wall of the first longitudinal support frame.

[0024] Through the above technical solution, when the first moving frame moves, it slides on the inner wall of the protective plate, the transverse support frame, and the fixed frame, which can prevent the first moving frame from interfering with the rotation of the protective plate.

[0025] As a further description of the above technical solution:

[0026] Preferably, the first movable frame is slidably connected to the inner wall of the protective plate, the second movable frame is slidably connected to the bottom end of the protective plate, and a groove is provided on the front side of the protective plate.

[0027] With the above technical solution, when the second moving frame pushes the protective plate upward through the first moving frame, the worker can easily open the protective plate through the groove.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the first longitudinal support frame and the second longitudinal support frame are welded and fixed by the transverse support frame, so that the pipeline is installed in the support frame through the pipeline support frame and the reinforcing plate. The transverse support frame is fixed to the foundation by the groove, nut and connecting block. The protective plate is fixed by the fixing bolt so that the multiple reinforcing plates can achieve the effect of increasing the overall strength of the embedded frame.

[0030] 2. In this utility model, the first movable frame contacts the inner wall of the first longitudinal support frame, the protective plate, and the second movable frame. The top of the fixing bolt contacts the bottom of the protective plate, allowing the first movable frame to move downward. Through the fixing frame and pipeline, the protective plate rises and exposes the groove. The protective plate can then be lifted through the groove, achieving the effect of conveniently opening the protective plate. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0038] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides: a municipal underground pipeline pre-embedded frame, including a horizontal support frame 1, a first longitudinal support frame 2 fixedly connected to the front outer wall of the horizontal support frame 1, a second longitudinal support frame 3 fixedly connected to the rear side of the horizontal support frame 1, a protective plate 4 rotatably connected to the top of the second longitudinal support frame 3, two fixing bolts 15 slidably connected to the inner wall of the protective plate 4, multiple pipe support frames 8 slidably connected to the top of the horizontal support frame 1, a pipeline 7 slidably connected to the top of the pipe support frame 8, multiple reinforcing plates 9 slidably connected to the top of the pipeline 7, multiple pre-embedded bolts 12 slidably connected to the inner wall of the horizontal support frame 1, a nut 13 threadedly connected to the top of the pre-embedded bolts 12, and a lifting assembly 19 provided on the right side of the first longitudinal support frame 2;

[0039] Specifically, a support frame is formed by welding together the transverse support frame 1, the first longitudinal support frame 2, and the second longitudinal support frame 3. Multiple pipe support frames 8 are neatly arranged and placed in the reinforcing rib frame of the transverse support frame 1. Then, the pipeline 7 is placed on the pipe support frame 8, allowing the multiple pipe support frames 8 to support the pipeline 7. The sliding grooves at both ends of the reinforcing plate 9 are placed on the reinforcing ribs of the first longitudinal support frame 2 and the second longitudinal support frame 3, allowing the multiple reinforcing plates 9 to be placed in the support frame, which can strengthen the support frame. Then, the protective plate 4 is rotated so that the bottom end of the protective plate 4 contacts the first longitudinal support frame 2 and the reinforcing plate 9, so that the fixing bolts 15 can fix the protective plate 4, thereby increasing the overall strength of the embedded frame.

[0040] Reference Figure 2 and Figure 4 The lifting assembly 19 includes a fixed frame 16, which is fixedly connected to the outer wall of the first longitudinal support frame 2. A gear 17 is rotatably connected to the inner wall of the fixed frame 16. Two racks 18 are meshed at the tooth ends of the gear 17. A first movable frame 5 is fixedly connected to the left side of one rack 18, and a second movable frame 6 is fixedly connected to the right side of one rack 18.

[0041] Specifically, the rack 18 and gear 17 mesh to form a lifting structure, with the first movable frame 5, gear 17 and second movable frame 6 forming a lifting structure. When the first movable frame 5 is pressed down, the second movable frame 6 moves upward and contacts the bottom of the protective plate 4 through the rack 18 and gear 17, so that the front part of the protective plate 4 rises, thus facilitating the opening of the protective plate 4.

[0042] Reference Figure 3 A connecting block 14 is slidably connected to the outer wall of the transverse support frame 1. The connecting block 14 is slidably connected to the outer wall of the pre-embedded bolt 12. The pre-embedded bolt 12 is fixedly connected to the concrete. A nut 13 is slidably connected to the outer wall of the connecting block 14. The nut 13 is slidably connected to the outer wall of the transverse support frame 1.

[0043] Specifically, multiple pre-embedded bolts 12 are fixed with concrete, so that the support frame can be fixed in the pre-embedded channel by the pre-embedded bolts 12 and nuts 13. Then, the multiple support frames are fixed together by the connection of the connecting block 14, so as to prevent the foundation from loosening.

[0044] Reference Figure 1 and Figure 2 The reinforcing plate 9 is slidably connected to the outer wall of the first longitudinal support frame 2 and the outer wall of the second longitudinal support frame 3; the reinforcing plate 9 is slidably connected to the top of the transverse support frame 1 and the bottom of the protective plate 4; the fixing bolt 15 passes through the protective plate 4 and is threadedly connected to the first longitudinal support frame 2.

[0045] Specifically, the reinforcing plate 9 can be moved by the grooves at both ends of the reinforcing plate 9, so that the bottom end of the reinforcing plate 9 contacts the transverse support frame 1 and the top end contacts the protective plate 4. When the protective plate 4 is fixed to the support frame by the fixing bolts 15, the reinforcing plate 9 and the pipe support frame 8 fix the pipeline 7 and can support the protective plate 4, so that the number of reinforcing plates 9 can be adjusted according to the road conditions, thereby changing the compressive strength of the protective plate 4.

[0046] Reference Figure 2 The top of the reinforcing plate 9 is provided with a rectangular groove 10, and the pipe support frame 8 is slidably connected to the outer wall of the reinforcing plate 9.

[0047] Specifically, the rectangular groove 10 facilitates the installation and removal of the reinforcing plate 9, while the pipe support frame 8 can change its position and quantity at the top of the horizontal support frame 1, thus facilitating the maintenance of the pre-embedded frame.

[0048] Reference Figure 1 , Figure 2 and Figure 4 The first movable frame 5 is slidably connected to the inner wall of the fixed frame 16, and the second movable frame 6 is slidably connected to the outer wall of the fixed frame 16. The first movable frame 5 is slidably connected to the inner wall of the first longitudinal support frame 2, and the second movable frame 6 is slidably connected to the outer wall of the first longitudinal support frame 2. The first movable frame 5 is slidably connected to the inner wall of the protective plate 4, and the second movable frame 6 is slidably connected to the bottom end of the protective plate 4. A groove 11 is provided on the front side of the protective plate 4.

[0049] Specifically, the second movable frame 6 contacts the bottom of the protective plate 4 at its top, and the first movable frame 5 is kept stationary by the gear 17 and rack 18. Pressing the first movable frame 5 downwards can cause the second movable frame 6 to push the protective plate 4 upwards, exposing the groove 11. The protective plate 4 can then be lifted by the groove 11, thus facilitating the opening of the protective plate 4.

[0050] Working principle: By welding the transverse support frame 1, the first longitudinal support frame 2, and the second longitudinal support frame 3 into a support frame, multiple support frames are neatly arranged in the pre-embedded channel and fixed by pre-embedded bolts 12, nuts 13, and connecting blocks 14. Then, multiple pipe support frames 8 are neatly placed between the reinforcing ribs of the transverse support frame 1, and the pipeline 7 is placed on the multiple pipe support frames 8. Then, multiple reinforcing plates 9 are placed, with their inner walls contacting the pipeline 7 and their bottom ends contacting the transverse support frame 1. The protective plate 4 is installed on the second longitudinal support frame 3. The protective plate 4 is rotated so that its bottom end contacts the top end of the reinforcing plate 9 and its front side contacts the top end of the first longitudinal support frame 2. Two fixing bolts 15 pass through the protective plate 4 and are threadedly connected to the first longitudinal support frame 2 to fix the protective plate 4. The reinforcing plate 9 can fix the pipeline 7 and support the protective plate 4 through the protective plate 4, thereby increasing the overall strength of the pre-embedded frame.

[0051] By rotating the fixing bolt 15, the fixing bolt 15 is removed from the first longitudinal support frame 2, so that the protective plate 4 is no longer fixed. Then, the first moving frame 5 is pressed down with a wrench, so that the second moving frame 6 pushes the protective plate 4 upward through the fixing frame 16 and the gear 17, so that the groove 11 in the protective plate 4 is exposed, and the protective plate 4 is lifted through the groove 11, so as to facilitate the opening of the protective plate 4.

[0052] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
