Description

Technical Field

[0001] This utility model relates to the field of urban drainage pipeline technology, specifically a leak-proof connection structure for urban overpass drainage pipelines. Background Technology

[0002] To divert traffic and avoid congestion, municipal engineering projects often construct overpasses in areas with heavy traffic. This not only shortens the travel distance of vehicles but also alleviates road pressure. To ensure smooth drainage of overpasses, drainage pipes need to be installed to remove accumulated water through longitudinally and laterally connected pipes.

[0003] If the length of a pipe needs to be changed, or if it needs to be extended or reinforced, a connection structure needs to be installed to prevent the drainage pipe joints from loosening and leaking. Such connection structures often use steel hoops to reinforce and lock the outer wall of the pipe, but they lack the squeezing and fixing of the flange at the connection point. Although the pipe is clamped and fixed, there are still loosening and leakage problems.

[0004] Now, a novel leak-proof connection structure for drainage pipes in urban overpasses is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a leak-proof connection structure for drainage pipes in urban overpasses, so as to solve the problem of easy loosening of pipe connections mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a leak-proof urban overpass drainage pipe connection structure, comprising a base and a limiting groove. A limiting groove is provided between the two sides inside the base, and a bidirectional screw rod is movably connected between the two sides inside the limiting groove. Threaded sleeves are threadedly connected to the two sides outside the bidirectional screw rod. Mounting seats are fixed to the front and rear of the top of the threaded sleeves, and bolts are threadedly connected to the front of the mounting seats. A hinge rod is movably connected to the inner side of the mounting seats, and a connecting block is movably mounted on the top of the hinge rod. A cover is fixed to the side of the connecting block. Slots are provided laterally at the front and rear ends of the top of the base. A cavity is provided on the right side inside the base, and a worm gear is movably connected between the two sides below the cavity. A worm is movably connected between the front and rear of the upper part of the cavity. A motor is fixed to the right side of the rear of the base. A pipe body is movably arranged above the base, and a flange is fixed to the side of the pipe body.

[0007] Preferably, the output end of the motor is fixedly connected to the worm gear in front, and the worm gear is meshed above the worm wheel.

[0008] Preferably, a sleeve is fixed to the top of the connecting block, and a sliding rod is movably inserted into the sleeve. A connecting piece is fixed at the center between the top ends of the sliding rod, and a screw hole is provided in the connecting piece. A one-way screw is threaded into the screw hole, and a pressure block is movably connected to the bottom of the one-way screw. A bolt is threaded to the upper surface of the sleeve, and a pad is fixed at the center of the top of the base.

[0009] Preferably, the slide rod enters and exits the sleeve vertically, and the slide rod is symmetrically fixed at the four corners of the connecting piece.

[0010] Preferably, the cover has an inner cavity arranged longitudinally inside, and a sleeve block is movably connected in the inner cavity. A sliding piece is fixed at the center of the outer side of the sleeve block, and a bolt is threadedly connected in the sliding piece. A positioning hole is arranged longitudinally on the side of the outer end of the cover.

[0011] Preferably, the bolt is embedded between the positioning hole and the sliding plate, and the sleeve slides up and down in the inner cavity.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the leak-proof urban overpass drainage pipe connection structure not only realizes the compression fixing of the flange and the upper and lower clamping fixing, but also avoids the screws and nuts used for connection;

[0013] By fixing mounting seats at the front and rear of the top of the threaded sleeve, the base is installed on the bridge plate of the overpass. The motor is started and the worm gear is rotated. The worm gear turns the worm wheel and rotates the threaded sleeve in the limiting groove in a self-locking manner. This guides the mounting seats at the front and rear to slide along the groove. Then, the angle of the hinge rod on the surface of the mounting seat is adjusted and locked with bolts. This forces the cover installed on the upper connecting block to fit against the front and rear ends of the flange. Then, the sliding rods at the four corners of the bottom of the connecting piece are inserted into the sleeve for fixing, which can prevent the pipe from separating from the flange.

[0014] A pressure block is movably connected to the bottom of the one-way screw. The sliding rods at the four corners of the bottom of the connecting plate are longitudinally inserted into the sleeve. Rotating the outer bolt one can prevent the sliding rod from sliding out of the sleeve. At this time, the flange of the pipe body overlaps on the gasket. Rotating the one-way screw in the screw hole forces the pressure block to press against the top of the flange. Together with the gasket, it restricts the shaking of the pipe from both the top and bottom, and facilitates installation and disassembly.

[0015] By fixing a cover to the side of the connecting block, the position of the sleeve block is pre-adjusted along the slide of the inner cavity according to the installation position of the screw and nut on the flange surface. After aligning the slide and the positioning hole, the bolt is screwed in and tightened. When the cover is attached to the front and rear sides of the flange, it can be sleeved on the outside of the screw and nut to avoid misfitting between the connecting structure and the flange accessories, so that the cover fits flatly on the flange surface.

[0022] Please see Figure 1-4 An embodiment of this utility model provides a leak-proof urban overpass drainage pipe connection structure, including a base 1 and a limiting groove 2. The limiting groove 2 is provided between the two sides inside the base 1, and a bidirectional screw rod 4 is movably connected between the two sides inside the limiting groove 2. Threaded sleeves 3 are threadedly connected to the two sides outside the bidirectional screw rod 4. Mounting seats 18 are fixed to the front and rear of the top of the threaded sleeves 3, and bolts 19 are threadedly connected to the front of the mounting seats 18. A hinge rod 17 is movably connected to the inner side of the mounting seats 18, and a connecting block 10 is movably installed at the top of the hinge rod 17. A cover 25 is fixed to the side of the connecting block 10. The front and rear ends of the top of the base 1 are respectively provided with horizontal slots 20. A cavity 5 is provided on the right side inside the base 1, and a worm gear 6 is movably connected between the two sides below the cavity 5. A worm 7 is movably connected between the front and rear of the upper part of the cavity 5. A motor 8 is fixed to the right side of the rear of the base 1. A pipe body 9 is movably provided above the base 1, and a flange 16 is fixed to the side of the pipe body 9.

[0023] The output end of the motor 8 is fixedly connected to the worm 7, and the worm 7 is meshed and connected above the worm wheel 6;

[0024] Specifically, such as Figure 1 and Figure 2 As shown, the base 1 is installed on the bridge plate of the overpass. The motor 8 is started and the worm gear 7 is rotated. The worm gear 7 rotates the worm wheel 6, and the threaded sleeve 3 in the limiting groove 2 is rotated in a self-locking manner. The mounting seats 18 at the front and rear are guided to slide along the slot 20 respectively. Then the angle of the hinge rod 17 on the surface of the mounting seat 18 is adjusted and locked with bolt 19, which forces the cover 25 installed on the upper connecting block 10 to fit against the front and rear ends of the flange 16.

[0025] A sleeve 11 is fixed to the top of the connecting block 10, and a slide rod 14 is movably inserted into the sleeve 11. A connecting piece 12 is fixed at the center between the top ends of the slide rod 14, and a screw hole 23 is provided in the connecting piece 12. A one-way screw rod 13 is threaded into the screw hole 23, and a pressure block 22 is movably connected to the bottom of the one-way screw rod 13. A bolt 15 is threaded on the upper surface of the sleeve 11. A pad 21 is fixed at the center of the top of the base 1. The slide rod 14 enters and exits the sleeve 11 vertically, and the slide rod 14 is symmetrically fixed at the four corners of the connecting piece 12.

[0026] Specifically, such as Figure 1 and Figure 3 As shown, the sliding rods 14 at the four corners of the bottom of the connecting piece 12 are inserted longitudinally into the sleeve 11. Then, the outer bolt 15 is rotated to prevent the sliding rods 14 from sliding out of the sleeve 11. At this time, the flange 16 of the pipe body 9 overlaps on the gasket 21. Then, the one-way screw 13 in the screw hole 23 is rotated to force the pressure block 22 to press against the top of the flange 16, which together with the gasket 21 restricts the shaking of the pipe from both the top and bottom.

[0027] The cover 25 has an inner cavity 28 arranged longitudinally inside, and a sleeve block 29 is movably connected in the inner cavity 28. A sliding piece 24 is fixed at the center of the outer side of the sleeve block 29, and a bolt 26 is threadedly connected in the sliding piece 24. A positioning hole 27 is arranged longitudinally on the side of the outer end of the cover 25. The bolt 26 is embedded between the positioning hole 27 and the sliding piece 24. The sleeve block 29 slides up and down in the inner cavity 28.

[0028] Specifically, such as Figure 1 and Figure 4 As shown, according to the installation position of the screws and nuts on the surface of the flange 16, the position of the sleeve block 29 is adjusted in advance along the slide of the inner cavity 28. After aligning the slide plate 24 with the positioning hole 27, the bolt 26 is screwed in and tightened. When the cover 25 is attached to the front and rear sides of the flange 16, it can be sleeved on the outside of the screws and nuts to avoid the connection structure from not fitting the accessories of the flange 16.

[0029] Working principle: In use, the position of the sleeve 29 is pre-adjusted along the slide of the inner cavity 28 according to the installation position of the screws and nuts on the flange 16. After aligning the slide plate 24 with the positioning hole 27, the bolt 26 is screwed in and tightened. When the cover 25 is attached to the front and rear sides of the flange 16, it can be sleeved on the outside of the screws and nuts. Then, the base 1 is installed on the bridge plate of the overpass. The motor 8 is started and the worm gear 7 is rotated. The worm gear 7 rotates the worm wheel 6, which rotates the threaded sleeve 3 in the limiting groove 2 in a self-locking manner, guiding the mounting seats 18 at the front and rear to slide along the slot 20 respectively. Then, the position is adjusted. The angle of the hinge rod 17 on the surface of the mounting base 18 is adjusted and locked with bolt 2 19, forcing the cover 25 installed on the upper connecting block 10 to fit against the front and rear ends of the flange 16. Then, the sliding rods 14 at the four corners of the bottom of the connecting piece 12 are inserted into the sleeve 11 for fixation. The sliding rods 14 at the four corners of the bottom of the connecting piece 12 are longitudinally inserted into the sleeve 11. Then, the outer bolt 15 is rotated to prevent the sliding rods 14 from sliding out of the sleeve 11. At this time, the flange 16 of the pipe body 9 overlaps on the gasket 21. Then, the one-way screw 13 in the screw hole 23 is rotated to force the pressure block 22 to press against the top of the flange 16 for reinforcement.
