Description

Technical Field

[0001] This utility model relates to the field of concrete drainage pipe technology, and more specifically, to a concrete drainage pipe that is easy to connect and install. Background Technology

[0002] Concrete drainage pipes are precast pipes made primarily of cement and aggregates, molded and cured using molds. They are characterized by high strength, corrosion resistance, and long service life. Currently, the biggest problem with existing reinforced concrete drainage pipes with spliced ​​joints is the poor sealing effect at the joints, allowing some sewage to seep into the soil through the gaps between the pipes during drainage.

[0003] To solve the above problems, a search revealed that CN222687511U discloses a reinforced concrete drainage pipe that is easy to connect. The specification states that: a steel cage is provided inside the concrete pipe, and connecting plates are provided at both ends of the steel cage. A sealing joint is provided between two adjacent concrete pipes, and the sealing joint is connected to the two adjacent concrete pipes by bolts.

[0004] However, this type of easily connectable reinforced concrete drainage pipe still has certain limitations in practical applications. Specifically, the connection method relies on two sealing joints fastened with bolts. During installation, the joint ends of the two pipe sections must first be pushed together before the bolts are inserted for fixation. However, if the bolt holes of the two joints are not perfectly aligned during the connection, the connection cannot be completed directly. It is necessary to repeatedly adjust the rotation angle of one pipe section to match the holes. This hole-aligning process not only increases the complexity of the installation operation but also significantly affects construction efficiency and reduces the convenience of pipe connection. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a concrete drainage pipe that is easy to install, so as to solve the problem that in the prior art, reinforced concrete drainage pipes use bolted connection sealing joints, but during installation, the pipe body angle needs to be repeatedly adjusted to align the bolt holes, which affects the construction efficiency and convenience.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a concrete drainage pipe that is easy to connect and install, comprising...

[0007] The pipe has sealing joints at both ends. Several mounting holes are formed inside the outer edge of each sealing joint, and the interior of each mounting hole is threaded. An upper clamping ring is installed on the outer surface of the pipe near the sealing joint, and a lower clamping ring is located below the upper clamping ring. The upper and lower clamping rings are connected by bolts at their junction. A threaded sleeve is threaded through the middle of both the upper and lower clamping rings, and a fastening bolt is threaded onto the inner surface of the threaded sleeve. An installation sleeve is located in the middle of the upper clamping ring, and a positioning mechanism is detachably installed on the inner surface of the installation sleeve.

[0008] The positioning mechanism includes a sleeve, the outer surface of the middle part of the sleeve is movably sleeved with the inner surface of the mounting sleeve, a movable rod is movably sleeved in the middle part of the sleeve, an adjusting column is fixedly installed at the left end of the movable rod, a limiting piece is fixedly installed at the right end of the movable rod, a threaded joint is fixedly installed on the right side of the limiting piece, and the outer surface of the threaded joint is threadedly sleeved with the inner surface of the sealing joint.

[0009] The movable rod has a protrusion fixedly installed on its outer surface in the middle, and the outer surface of the protrusion is slidably sleeved with the inner surface of the right end of the sleeve. A limiting piece two is fixedly installed on the outer surface of the movable rod near the right end of the sleeve. A spring is provided inside the sleeve. The spring is sleeved on the outside of the movable rod, and one end is fixedly connected to the inner wall of the left end of the sleeve, while the other end is in contact with the left side surface of the limiting piece two.

[0010] An auxiliary docking mechanism is fixedly installed on the outer surface of the lower hoop ring.

[0011] The auxiliary docking mechanism includes a support plate, the upper surface of which is fixedly installed with the lower surface of the lower hoop, pulleys fixedly installed on the bottom of both sides of the support plate, and a connecting ring and a wire rope respectively provided on both sides of the support plate.

[0012] The surface of the connecting ring is fixedly installed on the surface of the support plate. Two side plates are bolted to the surface of the support plate away from the connecting ring. The two side plates are installed in parallel, and a take-up roller is rotatably installed in the middle of the side end. A steel wire rope is connected to the outer surface of the take-up roller. A motor is fixedly installed on the side of the end of the side plate, and the output end of the motor is fixedly sleeved with the middle of the take-up roller.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In the above scheme, by setting up structures such as an upper clamping ring, a lower clamping ring, and a positioning mechanism, when installing two pipes together, the positioning mechanism can be inserted into the installation sleeve set at the top of the upper clamping ring. After the positioning mechanism is installed, it connects with the installation hole of the sealing joint, so that the upper clamping ring is positioned against the outer wall of the pipe. Thus, after the two pipes are placed on the ground with the support of the auxiliary docking mechanism, the installation holes connected to the threaded joints can be kept at the top and in a straight line, so that the positions of the two sealing joints are kept aligned. This makes the positioning effect during pipe installation more accurate and improves the installation efficiency.

[0015] In the above scheme, by setting an auxiliary docking mechanism, during the actual docking and installation process, the side plates and other structures can be pre-installed on the surfaces of the two support plates that are far apart by bolts. The free end of the steel wire rope connected to the surface of the rotatable winding roller in the middle of the two side plates is tied to the connecting ring set on the surface of the opposite support plate. When the two pipes approach each other, the two motors can be controlled to synchronously drive the winding rollers connected to the output ends to rotate, so that the connected steel wire rope is gradually wound on the outer surface of the winding roller, pulling the two support plates closer to each other.

[0022] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0023] As attached Figure 1 To be continued Figure 4 An embodiment of this utility model provides a concrete drainage pipe that is easy to connect and install, including...

[0024] Pipe 1, both ends of pipe 1 are provided with sealing joints 2, the outer edge of sealing joint 2 is provided with several installation holes, and the inside of the installation holes is threaded. An upper hoop ring 3 is installed on the outer surface of pipe 1 near the sealing joint 2, and a lower hoop ring 4 is provided below the upper hoop ring 3. The upper hoop ring 3 and the lower hoop ring 4 are connected by bolts at the junction. A threaded sleeve 5 is sleeved through the middle of the upper hoop ring 3 and the lower hoop ring 4. A fastening bolt 6 is threaded on the inner surface of the threaded sleeve 5. An installation sleeve 7 is provided in the middle of the upper hoop ring 3. A positioning mechanism 8 is detachably installed on the inner surface of the installation sleeve 7.

[0025] By setting threaded sleeve 5 and fastening bolt 6, the fastening bolt 6 set on the surface of upper hoop 3 and lower hoop 4 can be rotated and moved closer to the surface of pipe 1, so that the end of the fastening bolt 6 abuts against the outer wall of pipe 1, thereby improving the stability of the connection between the upper hoop 3, lower hoop 4 and other structures and the outer surface of pipe 1 and preventing slippage. In addition, the threaded sleeve 5 and fastening bolt 6 set on the mounting sleeve 7 are used to fix and release the sleeve 80, so that the positioning mechanism 8 can be disassembled after the sealing joint 2 is connected, and the positioning mechanism 8 can be reused.

[0026] The positioning mechanism 8 includes a sleeve 80, the outer surface of the middle part of the sleeve 80 is movably sleeved with the inner surface of the mounting sleeve 7, a movable rod 81 is movably sleeved in the middle part of the sleeve 80, an adjusting column 87 is fixedly installed at the left end of the movable rod 81, a limiting piece 82 is fixedly installed at the right end of the movable rod 81, and a threaded joint 83 is fixedly installed on the right side of the limiting piece 82, the outer surface of the threaded joint 83 is threadedly sleeved with the inner surface of the sealing joint 2.

[0027] Among them, a protrusion 84 is fixedly installed on the outer surface of the middle part of the movable rod 81, and the outer surface of the protrusion 84 is slidably sleeved with the inner surface of the right end of the sleeve 80. A limiting piece 85 is fixedly installed on the outer surface of the movable rod 81 near the right end of the sleeve 80. A spring 86 is provided inside the sleeve 80. The spring 86 is sleeved on the outside of the movable rod 81, and one end is fixedly connected to the inner wall of the left end of the sleeve 80, and the other end is in contact with the left side surface of the limiting piece 85.

[0028] By setting up structures such as protrusion 84 and spring 86, after all the remaining mounting holes of the two sealing joints 2 are connected by bolts, the threaded joint 83 is first screwed out from the inside of the mounting hole. Then, the adjusting column 87 is moved away from the sealing joint 2 at the joint, causing the movable rod 81 to slide along the inside of the sleeve 80. The limiting piece 85 presses the spring 86 set in the inner cavity of the sleeve 80. After the protrusion 84 moves into the inside of the sleeve 80 along the inner wall of the right end of the sleeve 80, the movable rod 81 can be rotated appropriately so that the protrusion 84 abuts against the inner wall of the right side of the sleeve 80, so that the threaded joint 83 and other structures are away from the sealing joint 2, which facilitates the connection of the corresponding mounting holes and avoids interference problems.

[0029] Among them, the outer surface of the lower hoop 4 is fixedly installed with an auxiliary docking mechanism 9.

[0030] The auxiliary docking mechanism 9 includes a support plate 90, the upper surface of which is fixedly installed with the lower surface of the lower hoop 4. Pulleys 91 are fixedly installed on the bottom of both sides of the support plate 90, and wire rings 92 and steel wire ropes 96 are respectively provided on both sides of the support plate 90.

Two side plates 93 are bolted to the surface of the support plate 90 away from the connecting ring 92. The two side plates 93 are installed in parallel, and a take-up roller 95 is rotatably installed in the middle of the side end. A wire rope 96 is connected to the outer surface of the take-up roller 95. A motor 94 is fixedly installed on the side of the end of the side plate 93. The output end of the motor 94 is fixedly sleeved with the middle of the take-up roller 95.

[0032] The working process of this utility model is as follows:

[0033] When installing two pipes 1 together, first insert the positioning mechanism 8 into the mounting sleeve 7 at the top of the upper hoop 3, and rotate the fastening bolt 6 inside the threaded sleeve 5 in the middle of the mounting sleeve 7 to fasten the sleeve 80 inside the mounting sleeve 7. Then, place the upper hoop 3 on the outer surface of the pipe 1 near the end to be connected and fixed, and align the threaded connector 83 with one of the mounting holes of the sealing connector 2. The adjusting column 87 drives the movable rod 81 and the threaded connector 83 to rotate, so that the threaded connector 83 rotates to fit the inner wall of the mounting hole of the threaded sealing connector 2 for connection. At this time, the positioning mechanism 8 will position the upper hoop 3 against the outer wall of the pipe 1. Then, connect the lower hoop 4 to the upper hoop 3 and the auxiliary docking mechanism 9 connected to the outer surface of the lower hoop 4 with bolts. In this way, the ends of the two pipes 1 to be connected are treated in the same way, so that after the two pipes 1 are placed on the ground with the support of the auxiliary docking mechanism 9, the mounting holes connected to the threaded connector 83 can be kept at the top and in a straight line.

[0034] In the actual installation process, the side plates 93 and other structures can be pre-installed on the surfaces of the two support plates 90 that are far apart by bolts. The free end of the steel wire rope 96 connected to the surface of the rotatable take-up roller 95 in the middle of the two side plates 93 is tied to the connecting ring 92 set on the surface of the opposite support plate 90. When the two pipes 1 come closer to each other, the two motors 94 can be controlled to synchronously drive the take-up roller 95 sleeved at the output end to rotate, so that the connected steel wire rope 96 is gradually wound on the outer surface of the take-up roller 95, pulling the two support plates 90 closer to each other.
