Description

Technical Field

[0001] This invention relates to the technical field of corrugated pipe connections, and in particular to a device for connecting double-walled corrugated pipes. Background Technology

[0002] Double-wall corrugated pipes are a common type of industrial sewage pipe, widely used in sewage systems of large factories and municipal engineering projects. Their diameter is typically DN200~DN1000, and they are a new type of plastic pipe with an annular corrugated outer wall and a smooth inner wall. They are generally connected using heat-shrink sleeves (tapes). This connection method involves overlapping fiber-reinforced heat-shrink sleeves at the joint. After cross-linking, polyethylene forms cross-linked bonds between the molecular chains, creating a three-dimensional network structure. However, this method requires leaving space in the trench for heating operations during construction, which is inconvenient. Summary of the Invention

[0003] To address the problems existing in the prior art, the present invention provides a device and method for connecting double-wall corrugated pipes.

[0004] On the one hand, the present invention provides a double-wall corrugated pipe connection device, which adopts the following technical solution: A device for connecting double-walled corrugated pipes includes a first semi-circular steel pipe, a second semi-circular steel pipe, and a round steel handle. The first and second semi-circular steel pipes are arranged in parallel. A first connecting block is fixed to both ends of the first semi-circular steel pipe, and a second connecting block is fixed to both ends of the second semi-circular steel pipe. Two sliding rods are arranged below the first and second semi-circular steel pipes. One end of the sliding rod is fixed to the first connecting block, and the end of the sliding rod away from the first connecting block passes through the second connecting block and is slidably connected to it. A through groove is opened on the top surface of the second connecting block. A rack is fixed to the top of the sliding rod and passes through the through groove on the second connecting block. The round steel handle is U-shaped. A support block is fixed to the top surface of the second connecting block. A rotating shaft is rotatably connected between the two support blocks. A gear is fixed on the rotating shaft and meshes with the rack. A connecting plate is provided on one side of the gear and is rotatably connected to the rotating shaft. A ratchet is fixed to the side of the gear near the connecting plate, and ratchet teeth are installed on the connecting plate. The ratchet and ratchet teeth cooperate with each other. The two ends of the round steel handle are fixed to the corresponding connecting plates.

[0005] On the other hand, the present invention also discloses a method of using a double-wall corrugated pipe connection device, comprising the following steps: S1. First, place the sealing rubber ring coated with lubricant into the groove on the outer wall of the first bellows. Then, align the first bellows and the second bellows to ensure that at least four grooves on the outer wall of the first bellows are inserted into the socket.

[0006] S2. Place the first semi-circular steel pipe into one of the outer wall grooves of the first corrugated pipe, and place the second semi-circular steel pipe into one of the outer wall grooves of the second corrugated pipe.

[0007] S3. Close the interface. Rotate the round steel handle towards the first semi-circular steel pipe, and the rack moves towards the second corrugated pipe. When the round steel handle moves away from the first semi-circular steel pipe, the rack remains stationary. Repeat the above process to connect the first and second corrugated pipes in place.

[0008] Compared with the prior art, the present invention has the following technical effects: The device of the present invention is simple, convenient and safe to manufacture and use. It does not require leaving space at the bottom of the trench for heating operations, thus reducing labor costs. It is applicable to most application scenarios and can carry out construction with high efficiency while ensuring accuracy. Attached Figure Description

[0011] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 The present invention will be described in further detail below.

[0012] Reference Figures 1-6This invention discloses a device for connecting double-walled corrugated pipes, including a first corrugated pipe 1, a second corrugated pipe 2, a first semi-circular steel pipe 3, a second semi-circular steel pipe 4, and a round steel handle 7. The first semi-circular steel pipe 3 and the second semi-circular steel pipe 4 are arranged in parallel. A first connecting block 31 is fixed to both ends of the first semi-circular steel pipe 3, and a second connecting block 41 is fixed to both ends of the second semi-circular steel pipe 4. The radii of the first semi-circular steel pipe 3 and the second semi-circular steel pipe 4 are determined according to the diameter of the corrugated pipe. Two sliding rods 5 are provided below the first semi-circular steel pipe 3 and the second semi-circular steel pipe 4. One end of each sliding rod 5 is fixed to the first connecting block 31 by bolts. A through hole 42 is provided on the second connecting block 41, and the end of the sliding rod 5 away from the first connecting block 31 passes through the through hole 42, allowing the sliding rod 5 to slide along the through hole 42. A through groove 43 is provided on the top surface of the second connecting block 41. The through groove 43 communicates with the through hole 42. A rack 51 is fixed on the top of the sliding rod 5. The rack 51 is set along the length direction of the sliding rod 5 and passes through the through groove 43 on the second connecting block 41.

[0013] The round steel handle 7 is U-shaped. A support block 44 is fixed on the top surface of the second connecting block 41. A rotating shaft 45 is rotatably connected between the two support blocks 44. A gear 6 is fixed on the rotating shaft 45, and the gear 6 meshes with a rack 51. A connecting plate 48 is provided on one side of the gear 6, and the connecting plate 48 is rotatably connected to the rotating shaft 45. A ratchet 46 is fixed on the side of the gear 6 near the connecting plate 48, and a ratchet tooth 47 is installed on the connecting plate 48. The ratchet 46 and the ratchet tooth 47 cooperate with each other. Both ends of the round steel handle 7 are fixed to the corresponding connecting plates 48.

[0014] In use, the first semi-circular steel pipe 3 and the second semi-circular steel pipe 4 are placed into the grooves 12 on the outer walls of the first corrugated pipe 1 and the second corrugated pipe 2, respectively. When the round steel handle 7 is rotated towards the first semi-circular steel pipe 3, the connecting plate 48 drives the ratchet 47 to rotate, the ratchet 47 drives the ratchet 46 to rotate, the ratchet 46 drives the gear 6 to rotate, and the gear 6 drives the rack 51 to move, thereby moving the first semi-circular steel pipe 3 towards the second semi-circular steel pipe 4. When the round steel handle 7 is rotated away from the first semi-circular steel pipe 3, the connecting plate 48 drives the ratchet 47 to rotate, while the ratchet 46 remains stationary.

The first semi-circular steel pipe 3 can be fitted into the outer wall groove 12 of the first corrugated pipe 1, and the second semi-circular steel pipe 4 can be fitted into the outer wall groove 12 of the second corrugated pipe 2.

[0016] A housing can be fixed to the top of the second connecting block 41. The housing covers the support block 44, the connecting plate 48, and the gear 6 inside. The top of the housing has a clearance groove for the round steel handle 7 to rotate. The housing can protect the internal components.

[0017] This invention also discloses a method for connecting double-wall corrugated pipes, comprising the following steps: S1. When connecting the first corrugated pipe 1 and the second corrugated pipe 2, first place the sealing rubber ring 11 coated with lubricant into the outer wall groove 12 of the first corrugated pipe 1, and then align the first corrugated pipe 1 and the second corrugated pipe 2 to ensure that at least 4 outer wall grooves 12 of the first corrugated pipe 1 are inserted into the receiving interface 21.

[0018] S2. Place the first semi-circular steel pipe 3 into one of the outer wall grooves 12 of the first corrugated pipe 1, and place the second semi-circular steel pipe 4 into one of the outer wall grooves 12 of the second corrugated pipe 2.

[0019] S3. Close the interface, rotate the round steel handle 7 towards the direction of the first semi-circular steel pipe 3, and move the rack 51 towards the direction of the second corrugated pipe 2. When the round steel handle 7 rotates away from the first semi-circular steel pipe 3, the rack 51 remains stationary. Repeat the above process so that the end of the first corrugated pipe 1 near the receiving interface 21 of the second corrugated pipe 2 is inserted into the receiving interface 21, and the first corrugated pipe 1 and the second corrugated pipe 2 are connected in place.

[0020] The device of the present invention is simple, convenient and safe to manufacture and use. It does not require leaving space in the trench for heating operations, thus reducing labor costs. It is applicable to most application scenarios and can carry out construction with high efficiency while ensuring accuracy.

[0021] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention.
