Description

Technical Field

[0001] The present application relates to the technical field of concrete pipes, and in particular to a reinforced concrete pipe seam-breaking tool. Background Art

[0002] In recent years, with the continuous development of cities, urban drainage pressure has increased, and more rainwater has been collected. Solving urban drainage problems has become a thorny issue in the process of municipal road construction. Large-diameter concrete pipes are often used as rainwater drainage pipes in municipal road construction because they are less affected by the ground surface, have strong rigidity and low cost.

[0003] When concrete pipes are used, they are mostly used to discharge and transport rainwater from cities, reduce the drainage pressure in cities, reduce the accumulation of rainwater, and discharge rainwater through concrete pipes to facilitate urban construction and development.

[0004] When concrete pipes are used, they are mostly used for urban drainage to reduce urban drainage pressure. When installing concrete pipes, two adjacent pipes need to be connected and sealed with rubber rings to reduce water leakage in the concrete pipes and affect uneven settlement of the road surface. During installation, the concrete pipes are usually pushed and plugged by an excavator or a jack. However, when pushing and plugging, the rubber ring on the concrete pipe is likely to move, and the connection of the concrete pipe is likely to be not straight, which is likely to affect the seal between the two concrete pipes and cause water seepage in the concrete pipe. Utility Model Content

[0005] The purpose of the present application is to solve the problem that the rubber ring is easily moved and the pipe is not installed straight during the installation of the concrete pipe, and the present application provides a reinforced concrete pipe seam smashing tool.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0007] A reinforced concrete pipe seam pounding tool comprises a pipe body, wherein the pipe bodies are two and symmetrically arranged, a trumpet pipe is fixed to one end of the pipe body, one end of the pipe body corresponds to the trumpet pipe, a sealing ring is sleeved on the end of the pipe body away from the trumpet pipe, and a sealing mechanism is arranged between the two pipe bodies.

[0008] By adopting the above technical solution, the displacement of the pipe bodies during connection is reduced through the sealing mechanism, the impact on the sealing effect between the pipe bodies is reduced, the pipe bodies are arranged straightly, and water seepage at the pipe body connections is reduced.

[0009] Furthermore, the sealing mechanism comprises a fixing tube fixed at one end of the tube body, a fixing groove is provided in the bell tube, the fixing tube is matched with the fixing groove, and a sealing assembly is provided between the fixing tube and the bell tube.

[0010] By adopting the above technical solution, the fixed pipe is allowed to enter the fixed groove, which facilitates the straight docking of the pipe body and the sealing of the pipe body.

[0011] Furthermore, the sealing assembly includes a second sealing ring mounted on a fixed tube, a limiting groove is provided on the fixed tube, the second sealing ring is located in the limiting groove and extends out of the limiting groove, a sealing groove is provided in the trumpet tube, the sealing groove is located in the fixed groove and corresponds to the second sealing ring, and a limiting member is provided between the tube body and the first sealing ring.

[0012] By adopting the above technical solution, the fixed pipe drives the sealing ring 2 to move, so that the sealing ring 2 enters the sealing groove. When entering, the limiting groove limits the sealing ring 2, reducing the movement of the sealing ring 2, so that the fixed pipe conflicts with the bell mouth, reducing water seepage between the pipe bodies.

[0013] Furthermore, the limiting member includes a limiting ring fixed on the tube body, the limiting ring is in conflict with one side of the sealing ring, and fixing blocks are fixed on the limiting ring and distributed in an array.

[0014] By adopting the above technical solution, the limiting ring contacts the sealing ring 1, thereby reducing the movement of the sealing ring 1.

[0015] Furthermore, the surface shape of the sealing ring 1 is trapezoidal and inclined, and the sealing ring 1 is adapted to the inner wall of the trumpet tube.

[0016] By adopting the above technical solution, the inclination angle of the sealing ring is consistent with the angle of the inner wall of the bell mouth, thereby increasing the sealing effect and reducing water seepage between the pipe bodies.

[0017] Furthermore, limiting rods are fixed to the ends of the horn tubes and are distributed in an array, limiting holes are opened on the fixing block, and the limiting rods correspond to the limiting holes.

[0018] By adopting the above technical solution, the limiting rod slides in the limiting hole, limiting the tube body and reducing the deviation of the tube body.

[0019] Furthermore, a screw is fixed to one end of the limiting rod away from the bell tube.

[0020] By adopting the above technical solution, the external nut is screwed onto the screw rod so that the nut contacts the fixing block, and the limiting rod increases the fixation between the two tube bodies.

[0021] Furthermore, one end of the screw rod and the limiting hole are both arc-shaped.

[0022] By adopting the above technical solution, the arcuate end of the screw rod enters the arcuate end of the limiting hole, which is convenient for the staff to insert.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. When the concrete pipe is in use, the pipe body is pushed by an excavator or a jack to bring the two pipe bodies closer together, so that the fixed pipe enters the fixed groove, and the fixed pipe drives the second sealing ring to move, so that the second sealing ring enters the sealing groove. When entering, the limiting groove restricts the second sealing ring to reduce the movement of the second sealing ring, so that the fixed pipe conflicts with the bell mouth, and at the same time drives the first sealing ring to move, so that the first sealing ring enters the bell pipe and contacts the inner wall of the bell pipe. When in contact, the limiting ring contacts the first sealing ring to reduce the movement of the first sealing ring, so that the first sealing ring is close to the bell mouth, and the inclination angle of the first sealing ring is consistent with the angle of the inner wall of the bell mouth, reducing the movement of the second sealing ring and the first sealing ring, which is convenient for the straight arrangement of the pipe bodies, increases the sealing effect, and reduces the water seepage between the pipe bodies.

[0025] 2. When the concrete pipe is in use, when the pipe body moves, the limiting rod is opposite to the fixed block, and the limiting rod drives the screw to move, so that the arc-shaped end of the screw enters the arc-shaped end of the limiting hole, which is convenient for the staff to insert. The limiting rod slides in the fixed block to limit the pipe body and reduce the deviation of the pipe body. After the installation is completed, the external nut is screwed onto the screw rod so that the nut contacts the fixed block. The limiting rod increases the fixation between the two pipe bodies, reduces the unevenness during installation, and facilitates the installation of the pipe body. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The embodiment of the present application discloses a reinforced concrete pipe seam-breaking tool.

[0034] Reference Figure 1The reinforced concrete pipe seam pounding tool comprises a pipe body 1. The pipe bodies 1 are two and symmetrically arranged. A trumpet pipe 2 is fixed at one end of the pipe body 1. One end of the pipe body 1 corresponds to the trumpet pipe 2. A sealing ring 3 is sleeved on the end of the pipe body 1 away from the trumpet pipe 2. A sealing mechanism is arranged between the two pipe bodies 1.

[0035] When the concrete pipe is in use, the staff uses a crane to transport the concrete pipe to be installed to a suitable position corresponding to the pipe body 1, and then uses a sealing ring 3 to increase the sealing effect between the two pipe bodies 1. At the same time, the sealing mechanism is used to reduce the displacement of the sealing ring 3 when the pipe bodies 1 are connected, reduce the impact on the sealing effect between the pipe bodies 1, facilitate the straight arrangement of the pipe bodies 1, and reduce water seepage at the connection of the pipe bodies 1.

[0036] Reference Figure 2-Figure 4 The sealing mechanism includes a fixed tube 4 fixed at one end of the tube body 1, a fixed groove 5 is provided in the trumpet tube 2, the fixed tube 4 is matched with the fixed groove 5, and a sealing component is provided between the fixed tube 4 and the trumpet tube 2. The sealing component includes a sealing ring 7 sleeved on the fixed tube 4, a limiting groove 9 is provided on the fixed tube 4, the sealing ring 7 is located in the limiting groove 9 and extends out of the limiting groove 9, a sealing groove 6 is provided in the trumpet tube 2, the sealing groove 6 is located in the fixed groove 5 and corresponds to the sealing ring 7, and a limiting member is provided between the tube body 1 and the sealing ring 3. The limiting member includes a limiting ring 8 fixed on the tube body 1, the limiting ring 8 is in conflict with one side of the sealing ring 3, and a fixing block 11 is fixed on the limiting ring 8 and is distributed in an array. The surface shape of the sealing ring 3 is trapezoidal and inclined, and the sealing ring 3 is matched with the inner wall of the trumpet tube 2.

[0037] When the concrete pipe is in use, the pipe body 1 is pushed by an excavator or a jack, so that the two pipe bodies 1 are close to each other, so that the fixed pipe 4 enters the fixed groove 5, which is convenient for the straight docking of the pipe body 1. The fixed pipe 4 then drives the sealing ring 27 to move, so that the sealing ring 27 enters the sealing groove 6. When entering, the limiting groove 9 limits the sealing ring 27 to reduce the movement of the sealing ring 27, so that the fixed pipe 4 conflicts with the bell mouth, thereby increasing the sealing effect between the pipe bodies 1, and at the same time drives the sealing ring 13 to move, and the sealing ring 13 enters the bell pipe 2 and contacts the inner wall of the bell pipe 2. When contacting, the limiting ring 8 conflicts with the sealing ring 13, reducing the movement of the sealing ring 13, so that the sealing ring 13 is close to the bell mouth, and the inclination angle of the sealing ring 13 is consistent with the angle of the inner wall of the bell mouth, thereby increasing the sealing effect and reducing the water seepage between the pipe bodies 1.

[0038] Reference Figure 1 and Figure 2 The end of the horn tube 2 is fixed with a limiting rod 10 and is distributed in an array, and a limiting hole 12 is opened on the fixing block 11, and the limiting rod 10 corresponds to the limiting hole 12. A screw 13 is fixed to the end of the limiting rod 10 away from the horn tube 2. One end of the screw 13 and the limiting hole 12 are both arc-shaped.

[0039] When the concrete pipe is in use, when the pipe body 1 moves, the limiting rod 10 is opposite to the fixing block 11, and the limiting rod 10 drives the screw rod 13 to move, so that the arc-shaped end of the screw rod 13 enters the arc-shaped end of the limiting hole 12, which is convenient for the staff to insert. The limiting rod 10 slides in the limiting hole 12 to limit the pipe body 1 to reduce the deviation of the pipe body 1 and reduce the unevenness during installation. After the installation is completed, the external nut is screwed onto the screw rod 13 so that the nut contacts the fixing block 11, and the limiting rod 10 increases the fixation between the two pipe bodies 1.

[0040] The implementation principle of the reinforced concrete pipe seam-breaking tool of this embodiment is as follows: when the concrete pipe is used, the staff transports the concrete pipe to be installed to a suitable position by a crane, corresponding to the pipe body 1;

[0041] When the concrete pipe is used, the pipe body 1 is pushed by an excavator or a jack, so that the two pipe bodies 1 are close to each other, so that the fixed pipe 4 enters the fixed groove 5, which is convenient for the straight docking of the pipe body 1. The fixed pipe 4 then drives the sealing ring 2 7 to move, so that the sealing ring 2 7 enters the sealing groove 6. When entering, the limiting groove 9 limits the sealing ring 2 7, reduces the movement of the sealing ring 2 7, so that the fixed pipe 4 conflicts with the bell mouth, and increases the sealing effect between the pipe bodies 1. At the same time, the sealing ring 1 3 is driven to move, and the sealing ring 1 3 enters the bell pipe 2 and contacts the inner wall of the bell pipe 2. When contacting, the limiting ring 8 conflicts with the sealing ring 1 3, reduces the movement of the sealing ring 1 3, and makes the sealing ring 1 3 close to the bell mouth. The inclination angle of the sealing ring 1 3 is consistent with the inner wall angle of the bell mouth, thereby increasing the sealing effect and reducing the water seepage between the pipe bodies 1.

[0042] When the tube body 1 moves, the limiting rod 10 is opposite to the fixing block 11, and the limiting rod 10 drives the screw rod 13 to move, so that the arc-shaped end of the screw rod 13 enters the arc-shaped end of the limiting hole 12, which is convenient for the staff to insert. The limiting rod 10 slides in the fixing block 11 to limit the tube body 1 to reduce the deviation of the tube body 1 and reduce the unevenness during installation. After the installation is completed, the external nut is screwed onto the screw rod 13 so that the nut contacts the fixing block 11, and the limiting rod 10 increases the fixation between the two tube bodies 1.
