Description
Technical Field
[0001] The utility model relates to the technical field of pipeline installation, and relates to a concrete pipeline installation and docking device. Background Technique
[0002] Concrete pipelines are widely used pipelines, mainly made of materials such as cement, gravel, and sand. Concrete pipelines generally have the characteristics of strong load-bearing capacity, good durability, not easy to age, heat resistance, corrosion resistance, etc., so they are widely used in various projects. During the installation process of concrete pipelines, docking devices are also required to facilitate the connection between adjacent concrete pipelines.
[0003] CN 218326680 U discloses a concrete pipeline nozzle docking device. By setting an upper connecting piece and a lower connecting piece that can clamp and fix the docking nozzles of the concrete pipeline body, the support and fixation of the docking nozzles of the concrete pipeline body are realized, effectively improving the connection strength and connection stability between the nozzles of the concrete pipeline. Although it can realize the stable docking of adjacent concrete pipelines and improve the docking and installation efficiency of adjacent concrete pipelines, it lacks a more efficient sealing structure. During the docking process of adjacent concrete pipelines, it is difficult to effectively seal the pipeline connection, resulting in easy leakage and leakage at the pipeline connection.
[0004] Therefore, it is of great practical significance to develop a concrete pipeline installation and docking device with good sealing effect. Summary of the Utility Model
[0005] Due to the above-mentioned defects in the prior art, the utility model provides a concrete pipeline installation and docking device with good sealing effect, which is reasonable in design and simple in structure. It can not only realize the rapid docking and installation of concrete pipelines, but also effectively seal the pipeline connection, overcoming the defect of poor sealing effect of the current concrete pipeline docking device.
[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0007] A concrete pipeline installation and docking device includes concrete pipeline unit sections;
[0008] The two ends of the concrete pipeline unit section are respectively sleeved and fixed with a first docking ring and a second docking ring. The outer edges of the first docking ring and the second docking ring are respectively provided with a plurality of mutually matching positioning grooves in a circular shape. At the positioning grooves, there is a limiting component for fixing the first docking ring and the second docking ring of adjacent concrete pipeline unit sections;
[0009] On the inner wall of one end of the concrete pipe unit section, a docking groove is opened, and a plurality of clamping grooves are annularly arranged on the inner wall of the docking groove. On the outer wall of the other end of the concrete pipe unit section, a clamping block matching the clamping groove is fixed.
[0010] The concrete pipe installation and docking device of the utility model has a reasonable structural design. The adjacent concrete pipe unit sections are quickly docked by using the docking groove, the clamping groove and the clamping block, and the fixation and sealing are realized through the mutually matching positioning grooves and the limiting components on the first docking ring and the second docking ring. The overall structure is relatively simple and the operation is simple. The overall sealing effect is good and the application prospect is good.
[0011] As a preferred technical solution:
[0012] For a concrete pipe installation and docking device as described above, a first sealing ring and a second sealing ring are sleeved on the end of the concrete pipe unit section where the clamping block is fixed, and the first sealing ring and the second sealing ring are respectively located on both sides of the clamping block. The presence of the first sealing ring and the second sealing ring can further improve the sealing effect between adjacent concrete pipe unit sections.
[0013] For a concrete pipe installation and docking device as described above, both the first docking ring and the second docking ring are coaxial with the concrete pipe unit section.
[0014] For a concrete pipe installation and docking device as described above, at least one threaded hole is opened on each positioning groove.
[0015] For a concrete pipe installation and docking device as described above, the limiting component includes a limiting block and a locking bolt;
[0016] The longitudinal section of the limiting block is arranged in a concave structure. The two ends of the limiting block are respectively clamped in the positioning grooves opened on the outer edges of the first docking ring and the second docking ring. The locking bolts are connected to the inside of the left and right ends of the limiting block. The locking bolts match the threaded holes, and the locking bolts penetrate into the threaded holes and are threadedly connected with the threaded holes. By adjusting the locking bolts, the positioning grooves can be tightened, thereby improving the sealing effect between adjacent concrete pipe unit sections.
[0017] For a concrete pipe installation and docking device as described above, the two contact surfaces of the limiting block and the positioning groove are both inclined and the two contact surfaces are symmetric with respect to the docking surface of the adjacent concrete pipe unit sections. The presence of the inclined contact surfaces can improve the sealing effect between adjacent concrete pipe unit sections.
[0018] For a concrete pipe installation and docking device as described above, the side of the docking groove close to the concrete pipe unit section and the corresponding wall surface of the concrete pipe unit section are both inclined, further improving the sealing effect.
[0019] A concrete pipe installation and docking device as described above, wherein the card slots and the card blocks correspond one by one, and the adjacent concrete pipe unit joints are docked by engaging the card blocks through the card slots.
[0020] A concrete pipe installation and docking device as described above, wherein both the first sealing ring and the second sealing ring are elastic rubber sealing rings.
[0021] The above technical solutions are only a feasible technical solution of the present utility model, and the protection scope of the present utility model is not limited thereto. Those skilled in the art can reasonably adjust the specific design according to actual needs.
[0022] The above-mentioned utility model has the following advantages or beneficial effects:

[0024] (2) In the concrete pipe installation and docking device of the present utility model, the presence of the first sealing ring and the second sealing ring can further improve the sealing effect between adjacent concrete pipe unit joints.
[0025] (3) In the concrete pipe installation and docking device of the present utility model, since both the side of the docking slot near the concrete pipe unit joint and the corresponding wall surface of the concrete pipe unit joint are inclined, during the docking installation of adjacent concrete pipe unit joints, the first sealing ring is fully extruded, and with the cooperation of the second sealing ring, double sealing of the connection between adjacent two concrete pipe unit joints can be achieved, and the sealing is more efficient, which can avoid leakage problems at the connection of pipe unit joints to the greatest extent.
[0026] (4) In the concrete pipe installation and docking device of the present utility model, after the adjacent two concrete pipe unit joints are docked, a plurality of "concave"-shaped limiting blocks can be sequentially inserted into the positioning slots opened on the outer edges of the first docking ring and the second docking ring. Since the interfaces between the left and right ends of the limiting block and the positioning slot are both inclined, when the limiting block is installed, an extrusion force that makes the first docking ring and the second docking ring approach each other can also be applied, which is convenient for the connection between the two concrete pipe unit joints to be tighter. Subsequently, tools such as a wrench can be used to tighten the locking bolts, so that one end of the locking bolt extends into the threaded hole, which is convenient for positioning the limiting block and can ensure the stable connection and good sealing effect between the two concrete pipe unit joints.

Specific embodiments
[0034] The following further illustrates the structure in the present utility model with reference to the drawings and specific embodiments, but it is not a limitation of the present utility model.
[0035] Embodiment 1
[0036] A concrete pipe installation and docking device, as Figures 1 to 5 shown, includes a plurality of concrete pipe unit sections 1;
[0037] At both ends of the concrete pipe unit section 1, a first docking ring 2 and a second docking ring 3 are respectively sleeved and fixed. The first docking ring 2 and the second docking ring 3 are coaxial with the concrete pipe unit section 1. A plurality of mutually matching positioning grooves 4 are annularly provided on the outer edges of the first docking ring 2 and the second docking ring 3. A threaded hole 5 is provided on each positioning groove 4. A limiting component 6 for fixing the first docking ring 2 and the second docking ring 3 of adjacent concrete pipe unit sections 1 is provided at the positioning groove 4. The limiting component 6 includes a limiting block 61 and a locking bolt 62. The longitudinal section of the limiting block 61 is arranged in a concave shape. The two ends of the limiting block 61 are respectively clamped in the positioning grooves 4 opened on the outer edges of the first docking ring 2 and the second docking ring 3. Locking bolts 62 are connected to the inside of the left and right ends of the limiting block 61. The locking bolts 62 are matched with the threaded holes 5. The locking bolts 62 penetrate into the threaded holes 5 and are threadedly connected with the threaded holes 5. The two contact surfaces of the limiting block 61 and the positioning groove 4 are both inclined and the two contact surfaces are symmetric with respect to the docking surface of adjacent concrete pipe unit sections 1. When the limiting block 61 is installed, it can also apply a squeezing force that makes the first docking ring 2 and the second docking ring 3 approach each other, facilitating the connection between the two concrete pipe unit sections 1 to be tighter. By using the settings of the first docking ring 2 and the second docking ring 3, the stable connection between adjacent two concrete pipe unit sections 1 is facilitated;
[0038] A docking groove 7 is opened on the inner wall of one end of the concrete pipe unit section 1. A plurality of clamping grooves 8 are annularly provided on the inner wall of the docking groove 7. A clamping block 9 that matches the clamping groove 8 is fixed on the outer wall of the other end of the concrete pipe unit section 1. The clamping grooves 8 and the clamping blocks 9 are in one-to-one correspondence. The clamping blocks 9 are clamped through the clamping grooves 8 to achieve the docking of adjacent concrete pipe unit sections 1, facilitating the stable docking between the two concrete pipe unit sections 1, avoiding relative rotation between the two, and also facilitating the sealing at the connection between the two concrete pipe unit sections 1. A first sealing ring 10 and a second sealing ring 11 are sleeved on the end of the concrete pipe unit section 1 where the clamping block 9 is fixed, and the first sealing ring 10 and the second sealing ring 11 are respectively located on both sides of the clamping block 9. The first sealing ring 10 and the second sealing ring 11 are both elastic rubber sealing rings (with more efficient and stable sealing effect). The side of the docking groove 7 close to the concrete pipe unit section 1 and the corresponding wall surface of the concrete pipe unit section 1 are both inclined.
[0039] After verification, the concrete pipe installation and docking device of the utility model has a reasonable structural design. The quick docking of adjacent concrete pipe units is realized by using the clamping grooves and clamping blocks, and the fixation and sealing are realized through the mutually matching positioning grooves and limiting components on the first docking ring and the second docking ring. The presence of the first sealing ring and the second sealing ring can further improve the sealing effect between adjacent concrete pipe units. Since both the side of the docking groove near the concrete pipe unit and the corresponding wall surface of the concrete pipe unit are inclined, during the docking and installation process of adjacent concrete pipe units, the first sealing ring is fully extruded, and with the cooperation of the second sealing ring, double sealing of the connection between two adjacent concrete pipe units can be achieved, with more efficient sealing and the maximum avoidance of leakage problems at the joints of the pipe units. After the docking of two adjacent concrete pipe units, multiple "concave"-shaped limiting blocks can be inserted into the positioning grooves opened on the outer edges of the first docking ring and the second docking ring in sequence. Since the interfaces between the left and right ends of the limiting block and the positioning groove are both inclined, when the limiting block is installed, an extrusion force that makes the first docking ring and the second docking ring approach each other can also be applied, facilitating the closer connection between the two concrete pipe units. Subsequently, tools such as wrenches can be used to tighten the locking bolts, so that one end of the locking bolt extends into the threaded hole, which is convenient for positioning the limiting block and ensuring the stable connection and good sealing effect between the two concrete pipe units. The overall structure is relatively simple and the operation is simple, with a good sealing effect and good application prospects.
