Description

Technical Field

[0001] This utility model belongs to the field of prefabricated well technology, and in particular relates to a positioning and fixing bracket for prefabricated well wall embedded pipes. Background Technology

[0002] Precast manholes are mainly used for urban drainage, water supply, and power and communication. Their core function is to intercept sewage by connecting it to the pipeline, preventing sewage from being directly discharged into natural water bodies and directing sewage to sewage treatment plants. They also serve as pipeline connecting components, enabling the transition and connection of pipes of different specifications. Pre-embedded pipe fittings are installed inside the precast manholes to facilitate the later placement of cables. To prevent the pre-embedded pipe fittings from moving during installation, positioning and fixing brackets are used to secure their positions.

[0003] A search revealed a patent document with publication number CN213539061U, which discloses a pre-embedded component and installation structure suitable for underground integrated pipe gallery supports. This includes an inner wall of the pipe gallery, pre-embedded bolt cylinders, a longitudinal mounting plate, bolt holes, connecting bolts, a transverse mounting frame, an upper fixing plate, a lower fixing plate, a storage frame, positioning holes, a positioning buffer frame structure, a pipe fitting fixing frame structure, a side connecting seat, and an adjustable longitudinal support structure. The pre-embedded bolt cylinders are embedded in the inner right side of the inner wall of the pipe gallery. The longitudinal mounting plate is located on the upper and lower parts of the right side of the inner wall of the pipe gallery. A shock-absorbing spring is sleeved on the outside of the positioning rod and simultaneously located inside the limiting plate and the positioning hole, which facilitates the use of the pipe fittings within the pipe fitting fixing frame structure for shock absorption during use. A threaded rod is inserted into the inside of the side branch pipe and threadedly connected to the fixing nut, allowing for convenient adjustment of the distance between the bottom of the side branch pipe and the anti-slip foot as needed during use.

[0004] However, the positioning and fixing brackets for prefabricated well wall embedded pipes still have the following drawbacks in actual use: 1. First, using clips to position and fix the embedded pipe fittings is cumbersome, increases the workload of workers, and also increases the time for positioning and fixing the embedded pipe fittings, thus reducing work efficiency. 2. Secondly, it is impossible to cover the upper end of the embedded pipe fitting. During the concrete pouring process, it is impossible to avoid concrete entering the interior of the embedded pipe fitting. The entry of concrete will cause blockage of the embedded pipe fitting, which will cause inconvenience for the insertion of cables later.

[0005] To address this issue, we provide a positioning and fixing bracket for prefabricated well wall embedded pipes, which solves the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a positioning and fixing bracket for prefabricated well wall embedded pipes. By setting a positioning and fixing component, the operation steps for positioning and fixing the embedded pipes are simplified, the workload is reduced, and by setting a lifting component, the height of the movable plate is adjusted to block the upper port of the embedded pipe, thereby solving the technical problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a positioning and fixing bracket for prefabricated well wall embedded pipe fittings, comprising a base plate, a bracket on the top of the base plate, and a positioning and fixing assembly inside the bracket. The positioning and fixing assembly includes a threaded screw that passes through the bracket. A clamping block is symmetrically arranged below a movable plate rotatably connected to the lower end of the screw. An upper connecting rod hinged to the upper surface of the clamping block is hinged to the lower surface of the movable plate, and a lower connecting rod hinged to the lower surface of the clamping block is hinged to the inner wall of the bracket. A lifting assembly is symmetrically arranged on the lower surface of the bracket. The lifting assembly includes a connecting seat symmetrically fixed to the base plate. A screw block is fixed to the upper end of a movable rod rotatably connected to the connecting seat. An internally threaded cylinder threaded to the peripheral side wall of the screw block is connected to the lower surface of the bracket.

[0008] The present invention is further configured such that the substrate is a U-shaped structure and the support is an inverted U-shaped structure.

[0009] The present invention is further configured such that bolts are threadedly connected to the upper surface of the substrate, and the four bolts are distributed in a rectangular array.

[0010] The present invention is further configured such that guide rods are fixedly connected to the two inner side walls of the bracket in a rectangular array, and sliding grooves are provided on the two side walls of the movable plate in a rectangular array, the sliding grooves being slidably connected to the outside of the guide rods.

[0011] The present invention is further configured such that the clamping block has an arc-shaped structure and an anti-slip pad is provided on the inner wall of the clamping block.

[0012] The present invention is further configured such that a cover plate is installed at the lower end of the internally threaded cylinder, a through hole is provided on the lower surface of the cover plate, and a rubber ring is provided on the inner wall of the through hole.

[0013] The present invention is further configured such that the inner diameter of the through hole is smaller than the outer diameter of the screw block, and the inner diameter of the through hole is larger than the outer diameter of the movable rod.

[0014] This utility model has the following beneficial effects: 1. This utility model, by setting up a positioning and fixing component, allows the movable plate to move downward when the screw is rotated clockwise, and the upper and lower connecting rods to move, reducing the distance between the two clamping blocks until the embedded pipe is clamped and its position is fixed; conversely, rotating the screw counterclockwise moves the movable plate upward, increasing the distance between the two clamping blocks and releasing the embedded pipe, thus simplifying the operation steps and reducing the workload.

[0015] 2. This utility model features a lifting assembly. When the movable rod is rotated clockwise, the screw block rotates accordingly, the internal threaded cylinder moves downward, the bracket moves downward, and the movable plate moves downward until it abuts against the upper end of the embedded pipe fitting, preventing concrete from entering the interior of the embedded pipe fitting and facilitating the insertion of cables into the embedded pipe fitting later. Conversely, when the movable rod is rotated counterclockwise, the movable plate moves upward, removing the obstruction to the upper end of the embedded pipe fitting. Attached Figure Description

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

[0020] Example 1 Please see Figure 1 , Figure 3 and Figure 5 This utility model is a positioning and fixing bracket for pre-embedded pipes in a precast well wall, including a base plate 1 and bolts 101. Bolts 101 are used to fix the position of the base plate 1 on the precast well. Specifically, a bracket 102 is provided above the base plate 1, and bolts 101 are threadedly connected to the upper surface of the base plate 1. The four bolts 101 are distributed in a rectangular array. Furthermore, the substrate 1 has a U-shaped structure, and the support 102 has an inverted U-shaped structure; The operation process of this embodiment is as follows: the operator places the substrate 1 on the precast well, rotates the bolt 101 clockwise to fix the position of the substrate 1 on the precast well; conversely, rotates the bolt 101 counterclockwise to remove the substrate 1 from the precast well.

[0021] Example 2 Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 Based on the first specific embodiment, a positioning and fixing component 2 is provided. The positioning and fixing component 2 includes a screw 201, a movable plate 202, a clamping block 203, an upper connecting rod and a lower connecting rod 205. Rotating the screw 201 clockwise reduces the distance between the two clamping blocks 203 and fixes the embedded pipe. Rotating the screw 201 counterclockwise increases the distance between the two clamping blocks 203 and loosens the embedded pipe. This simplifies the operation steps, quickly positions and fixes the embedded part, and reduces the workload. Specifically, a screw 201 is threaded through the support 102. The lower end of the screw 201 is rotatably connected to the movable plate 202, and a clamping block 203 is symmetrically provided below it. The upper connecting rod 204, which is hinged to the upper surface of the clamping block 203, is hinged to the lower surface of the movable plate 202. The lower connecting rod 205, which is hinged to the lower surface of the clamping block 203, is hinged to the inner wall of the support 102. Furthermore, guide rods 103 are fixedly connected to the rectangular array on the two inner side walls of the bracket 102, and sliding grooves 202a are opened on the rectangular array on the two side walls of the movable plate 202. The sliding grooves 202a are slidably connected to the outside of the guide rods 103. The clamping block 203 has an arc-shaped structure, and anti-slip pads 203a are provided on the inner wall of the clamping block 203. The operation process of this embodiment is as follows: Rotate the screw 201 clockwise, the movable plate 202 moves downward, the upper connecting rod 204 and the lower connecting rod 205 move, and the two clamping blocks 203 move towards each other to reduce the distance and clamp the embedded pipe fitting; Conversely, rotate the screw 201 counterclockwise, the movable plate 202 moves upward, the upper connecting rod 204 and the lower connecting rod 205 move, and the two clamping blocks 203 move away from each other to increase the distance and release the embedded pipe fitting.

[0022] Example 3 Please see Figure 5 and Figure 6 Based on specific embodiments one and two, a lifting assembly 3 is provided. The lifting assembly 3 includes an internal threaded cylinder 301, a movable rod 302, a connecting seat 303, and a screw block 304. When the movable rod 302 is rotated counterclockwise, the internal threaded cylinder 301 moves upward and the movable plate 202 moves upward. When the movable rod 302 is rotated clockwise, the movable plate 202 moves downward, blocking the upper entrance of the embedded pipe fitting, preventing concrete from blocking the embedded pipe fitting, and facilitating the entry of cables into the embedded pipe fitting later. Specifically, a connecting seat 303 is symmetrically fixed on the base plate 1. A screw block 304 is fixed to the upper end of the movable rod 302 rotatably connected to the connecting seat 303. An internally threaded cylinder 301 threaded to the peripheral side wall of the screw block 304 is connected to the lower surface of the bracket 102. Furthermore, a cover plate 305 is installed at the lower end of the internal threaded cylinder 301. A through hole 305a is opened on the lower surface of the cover plate 305. A rubber ring 306 is provided on the inner wall of the through hole 305a. The inner diameter of the through hole 305a is smaller than the outer diameter of the screw block 304, and the inner diameter of the through hole 305a is larger than the outer diameter of the movable rod 302. The operation process of this embodiment is as follows: the operator rotates the movable rod 302 clockwise, the screw block 304 rotates accordingly, the internal threaded cylinder 301 moves downward, the bracket 102 moves downward, and the movable plate 202 moves downward until it abuts against the upper end of the embedded pipe fitting, blocking the upper port of the embedded pipe fitting; conversely, the operator rotates the movable rod 302 counterclockwise, the movable plate 202 moves upward, away from the upper port of the embedded pipe fitting.
