Description

Technical Field

[0001] This application relates to the field of building construction technology, and in particular to a sewage pipe for discharging concrete. Background Technology

[0002] During the pouring of concrete at construction sites, sewage pipes are widely used to ensure that the concrete is discharged smoothly into designated waste recycling areas.

[0003] Sewage pipelines mainly consist of the pipeline body and supporting structures. The pipeline body is typically made of high-strength rigid plastic or metal, including multiple sections of straight and curved pipes; the supporting structures ensure the stability of the pipeline in complex construction environments. The working principle relies on the weight of the concrete itself to allow it to flow within the pipeline, transporting it downwards from the top of the pipeline body to the recycling area.

[0004] Regarding the aforementioned technologies, the sewage pipes rely on the gravity of the concrete for transport, but the concrete usually contains impurities such as reinforcing bars and gravel. These impurities can easily cause blockages in the bends of the main pipe. The existing bends and straight pipes are connected by flange bolts, which makes disassembly and assembly quite cumbersome. Utility Model Content

[0005] To facilitate the disassembly and assembly of straight and curved pipes and improve maintenance and cleaning efficiency, this application provides a sewage pipe for discharging concrete.

[0006] The technical solution provided in this application for a sewage pipe for discharging concrete is as follows:

[0007] A sewage pipe for discharging concrete includes a pipe body, which includes several vertically arranged straight pipes, a bend for changing the conveying direction, and a connecting assembly connecting the straight pipes and the bend. The connecting assembly includes a sliding member slidably disposed on the bend, a fixing ring disposed on the straight pipe and inserted into the sliding member, and a locking member disposed on the fixing ring. The sliding member has a locking slot for the locking member to be inserted. When the locking member and the locking slot are engaged, part of the locking member is located in the locking slot, and the other part is located in the fixing ring.

[0008] By adopting the above technical solution, the connecting components connect straight pipes and bends to achieve the splicing of the main pipe body; the locking parts and locking slots cooperate to facilitate the connection and locking of the sliding parts and the fixing ring, making the connection between straight pipes and bends stable and easy to operate. Compared with the bolt connection of existing flanges, it is easier to disassemble and assemble, and improves maintenance and cleaning efficiency.

[0009] Optionally, the sliding component includes a sliding ring body and sliding arc plates spaced apart circumferentially along the sliding ring body. The end of the bent pipe is provided with a limiting ring. The limiting ring has a limiting through hole for the sliding arc plates to pass through. The sliding ring body extends outward and is provided with a first positioning part that abuts against one end face of the limiting ring. The sliding arc plates are provided with a second positioning part that abuts against the other end face of the limiting ring.

[0010] By adopting the above technical solution, the sliding component can be set to slide relative to the bent pipe by passing the sliding arc plate through the sliding arc hole, and the sliding component can be limited by the first positioning part and the second positioning part, so that the sliding component can slide within a certain range, which facilitates the connection assembly to quickly connect and disassemble the straight pipe and the bent pipe.

[0011] Optionally, the sliding arc plate is provided with a mounting groove for the second positioning part to be installed, and a reset elastic element connecting the second positioning part is provided in the mounting groove. When the sliding element and the fixing ring are fixed, the second positioning plate is placed on top of the fixing ring.

[0012] By adopting the above technical solution, the second positioning part is reset and placed on the top of the fixed ring using the reset elastic element, making the connection between the sliding part and the fixed ring more secure, and facilitating the quick installation and disassembly of the sliding part and the fixed ring.

[0013] Optionally, the second positioning part is provided with a guide slope on the side away from the first positioning part for the fixing ring to abut and push.

[0014] By adopting the above technical solution, when connecting straight pipes and curved pipes, the fixing ring can push the second positioning part along the guide slope, which facilitates the rapid connection between the sliding part and the fixing ring and improves assembly efficiency.

[0015] Optionally, the fixing ring has a radial groove for the locking member to slide. The radial groove extends radially along the axis of the straight pipe. The locking member is provided with a plunger member connected to the fixing ring. The inner wall of the radial groove is provided with two sets of plunger locking holes that cooperate with the plunger member along the sliding direction of the locking member.

[0016] By adopting the above technical solution, the locking component can slide radially on the fixed ring, and the position of the locking component can be locked by the cooperation between the plunger component and the plunger locking hole, thereby realizing the rapid connection of bent pipes and straight pipes.

[0017] Optionally, the locking member has a pull handle rotatably mounted on the side away from the locking slot, and the fixing ring has a handle limiting groove in the radial slide for limiting the arrangement of the pull handle.

[0018] By adopting the above technical solution, it is more convenient to operate the locking component to separate or engage with the locking slot. At the same time, rotating the pull handle can limit the pull handle to the handle limit groove, reducing the probability of the locking component and the plunger component disengaging.

[0019] Optionally, the retaining ring is slidably fitted with a limiting cover at the opening on the side of the radial groove away from the locking slot.

[0020] By adopting the above technical solution, the probability of foreign matter entering the radial groove and affecting the normal use of the locking component can be reduced, ensuring that the locking component and the locking slot can cooperate smoothly to achieve the connection of the bent pipe and the straight pipe.

[0021] Optionally, the inner wall of the bend is uniformly covered with an anti-sticking template, and the anti-sticking template and the inner wall of the bend are detachably connected.

[0022] By adopting the above technical solution, the anti-stick formwork avoids the blockage caused by impurities such as steel bars and gravel in the concrete at the bends, and the detachable anti-stick formwork is easy to replace and clean.

[0023] Optionally, the anti-stick template includes two sets of semi-circular arc templates, and the inner wall of the bent pipe is provided with an annular placement groove for arranging the arc templates.

[0024] By adopting the above technical solution, it is easy to install and disassemble the anti-stick formwork, and at the same time, it can prevent the anti-stick formwork from shaking inside the bend, effectively reducing the adhesion of impurities in the concrete at the bend and reducing the probability of blockage.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. By connecting straight and bent pipes with connecting components, compared with the traditional flange bolt connection method, the pipe disassembly and assembly steps are simplified, and the construction efficiency and maintenance convenience are improved;

[0027] 2. Laying anti-sticking template on the inner wall of the bend can reduce the adhesion of impurities in the concrete to the bend and reduce the possibility of blockage;

[0028] 3. The locking parts and locking slots of the connecting components work together to ensure the stability of the connection between straight and bent pipes. Attached Figure Description

Detailed Implementation

[0035] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0036] This application discloses a sewage pipe for discharging concrete.

[0037] Reference Figure 1 A sewage pipe for discharging concrete includes a pipe body 1, which includes a straight pipe 2, a bend 3, and a connecting component 4. Adjacent straight pipes 2 are fixedly connected by flanges. When it is necessary to adjust the discharge direction of concrete, the adjacent straight pipes 2 are connected by the bend 3. The bend 3 and the straight pipes 2 are quickly fixed by the connecting component 4.

[0038] The bend 3 is Z-shaped in the vertical direction and includes a connecting part 31 that is connected to the straight pipe 2 at both ends and an inclined part 32 located between the two connecting parts 31.

[0039] Reference Figure 2 and Figure 3 The connecting component 4 includes a sliding member 41 that is slidably disposed on the connecting part 31, a fixing ring 42 disposed on the straight pipe 2 and inserted into the fixing ring 42, and a locking member 43 disposed on the fixing ring 42 for locking the sliding member 41.

[0040] The sliding component 41 includes multiple sliding arc plates 411 and a sliding ring body 412 for connecting the multiple sliding arc plates 411. The multiple sliding arc plates 411 are circumferentially spaced along the axis of the sliding ring body 412. A limiting ring 44 for sliding arrangement of the sliding component 41 is fixedly installed on the outer wall of the bend 3. The limiting ring 44 has sliding arc holes 441 corresponding one-to-one with the sliding arc plates 411. The sliding ring body 412 extends outward to form a first positioning part 4121. The setting of the first positioning part 4121 increases the bottom contact area between the sliding component 41 and the limiting ring 44, thereby making the positioning effect of the sliding component 41 after locking more ideal.

[0041] A second positioning part 4111 is provided on the side of the sliding arc plate 411 away from the first positioning part 4121. The outer wall of the sliding arc plate 411 is provided with a mounting groove 4112 for sliding installation of the second positioning part 4111. The second positioning part 4111 slides radially along the connecting part 31. A reset elastic member 4113, which is a compression spring, is installed in the mounting groove 4112 of the sliding arc plate 411 to connect with the second positioning part 4111. The second positioning part 4111 has a guide slope 4114 on the side away from the first positioning part 4121. When the sliding arc plate 411 is inserted upwards into the fixing ring 42, the guide slope 4114 abuts against the fixing ring 42, causing the second positioning part 4111 to gradually slide into the mounting groove 4112. This embodiment takes the assembly of the top end of the bent pipe 3 and the bottom end of the straight pipe 2 as an example.

[0042] When the first positioning part 4121 and the limiting ring 44 come into contact, the second positioning part 4111 and the fixing ring 42 are staggered in the axial direction, so that the second positioning part 4111 slides out of the mounting groove 4112 under the action of the reset elastic member 4113 and comes into contact with the top of the fixing ring 42. The cooperation between the second positioning part 4111 and the first positioning part 4121 positions both ends of the sliding member 41.

[0043] The outer side of the locking arc plate has a locking slot 4115 for the locking member 43 to be inserted, and the locking member 43 slides radially along the axis of the straight tube 2. A radial groove 421 is provided on the fixing ring 42 for the locking member 43 to slide along, and the radial groove 421 penetrates the outer wall of the fixing ring 42. Both the upper and lower sides of the locking member 43 are provided with plunger members 431 fixedly connected to the fixing ring 42. The plunger member 431 includes a plunger housing, a plunger spring, and a plunger ball head. The plunger housing is interference-fitted into the locking member 43, and the plunger spring is vertically arranged, with its two ends fixed to the bottom of the plunger housing and the plunger ball head, respectively.

[0044] The inner wall of the radial groove 421 is provided with two sets of plunger locking holes 4211 for the insertion of the plunger ball head along the sliding direction of the locking member 43. One set of plunger locking holes 4211 is used to lock the locking member 43 in the unlocked state, and the other set of plunger locking holes 4211 is used to lock the locking member 43 when it is locked to the sliding member 41. When the locking member 43 is inserted into the sliding arc plate 411, part of the locking member 43 is located in the locking slot 4115, and the other part is fixed by the cooperation of the plunger member 431 and the plunger locking hole 4211, thereby fixing the sliding member 41 and the fixing ring 42, and completing the connection and fixation of the straight pipe 2 and the bent pipe 3.

[0045] To facilitate the operator's operation of the locking element 43, a pull handle 432 is also provided on the outer wall of the locking element 43. The pull handle 432 is generally in the shape of a straight line. The pull handle 432 is defined as having a straight line in the horizontal direction (first state) and a straight line in the vertical direction (second state). The length of the pull handle 432 in the second state is greater than the length of the radial groove 421. The pull handle 432 is rotatably mounted on the locking element 43, and the fixing ring 42 is also provided with a handle limiting groove 4212 within the radial groove 421 for limiting the pull handle 432 in the second state.

[0046] Reference Figure 4 The outer wall of the fixing ring 42 is also provided with a limiting cover plate 422 for covering the opening of the radial slide groove 421, and the limiting cover plate 422 is slidably mounted on the fixing ring 42. The fixing ring 42 has a circumferential slide rail 423 along the circumferential direction for arranging the limiting cover plate 422.

[0047] Reference Figure 5 The inner wall of the bend 3 is uniformly covered with anti-stick template 5. The anti-stick template 5 is made of high-density polyethylene, polypropylene and other materials, and has a smooth surface, which reduces the probability that the concrete will become one with the bend 3 after it solidifies.

[0048] The anti-stick template 5 includes two sets of semi-circular arc templates 51, which are connected by an interlocking structure. The bend 3 has an annular placement groove 321 on the inner wall of the inclined part 32 for arranging the anti-stick template 5.

[0049] The implementation principle of a sewage pipe for discharging concrete according to an embodiment of this application is as follows: When connecting the bend 3 and the straight pipe 2, the top of the bend 3 and the bottom of the straight pipe 2 are aligned, and then the sliding member 41 is slid upward so that the first positioning part 4121 is placed on the top of the fixing ring 42. Then the locking member 43 is pushed horizontally so that the locking member 43 is inserted into the locking slot 4115. The pull handle 432 is rotated so that the pull handle 432 is limited and arranged in the handle limiting groove 4212. Finally, the limiting cover plate 422 is moved so that the limiting cover plate 422 covers the side wall opening of the radial sliding groove 421.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
