Description

Technical Field

[0001] This utility model relates to the field of corrugated pipe docking technology, specifically a pre-treatment device for quick installation of flexible corrugated pipes. Background Technology

[0002] A corrugated pipe is a tubular elastic sensitive element made of foldable corrugated sheets connected along the folding and stretching direction. Due to its elasticity and the ability to generate displacement under pressure, axial force, lateral force or bending moment, it is widely used in building construction and factory production.

[0003] In the prior art, CN219358556U discloses a corrugated pipe docking device. Although the above-mentioned prior art has achieved the docking of corrugated pipes, in actual use, this prior art not only requires the purchase of multiple compatible motors, but also requires the addition of high-precision controllers, voltage regulator modules and complex circuit connection systems, which greatly increases the economic pressure of project procurement. In addition, the assembly precision requirements of motors and transmission components are stringent, and the wiring layout needs to take into account insulation and anti-interference design. During later maintenance, it is necessary to check the motor operating parameters, circuit continuity status and controller signal transmission stability one by one, which significantly increases the technical threshold of equipment debugging and maintenance. At the same time, it will also greatly increase the overall weight of the device. In scenarios such as outdoor pipeline construction where frequent mobile equipment is required, at least two people are needed to complete the transfer of the device, which greatly reduces the flexibility of single-person operation. Moreover, in the humid and dusty underground pipeline construction environment, electrical components are prone to failure due to moisture intrusion or dust accumulation, resulting in poor practicality and convenience. In view of this, we propose a flexible corrugated pipe quick installation pretreatment device to solve the above problems. Utility Model Content

[0013] Compared with the prior art, this utility model provides a pre-treatment device for quick installation of flexible corrugated pipes, which has the following advantages:

[0014] 1. This flexible corrugated pipe quick-installation pretreatment device, through the cooperation of structures such as fixing rods, guide rods, positioning blocks, positioning grooves, connecting blocks, moving plates, fixing plates, and adjusting screws, enables a large-scale movement of one side of the corrugated pipe in the initial docking stage. This quickly shortens the distance between the two corrugated pipes, reduces unnecessary fine-tuning time in the early stages, and effectively speeds up the construction progress. In addition, the small-scale, slow movement allows for more precise control of the corrugated pipe position, ensuring perfect alignment of the two pipe ends. This avoids inaccurate docking caused by excessive deviation in the early stages, reduces the risk of pipe deformation and damage, and eliminates the need to purchase multiple drive motors, controllers, and power modules, significantly reducing the overall cost in engineering applications.

This flexible corrugated pipe quick-installation pretreatment device achieves rapid fixation of the fixed half-ring through the cooperation of the first mounting plate, the second mounting plate, the L-shaped connecting rod, and the through groove, without the need for bolts or other structures, ensuring fixation efficiency. Subsequently, the grip and cam structures enable quick unlocking, further reducing disassembly and assembly steps and improving efficiency. In addition, the cooperation of the pressing plate, friction plate, friction ring, and torsion spring structures ensures the stability of the grip, effectively preventing it from rotating and ensuring the fixation effect of the two fixed half-rings.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5This utility model provides a technical solution: a flexible corrugated pipe quick installation pretreatment device, including two corrugated pipe bodies 1. Each corrugated pipe body 1 has two fixed semi-rings 2 on its exterior. First connecting plates 3 are fixedly connected to both sides of the two front fixed semi-rings 2, and second connecting plates 4 are fixedly connected to both sides of the two rear fixed semi-rings 2. A fixing rod 5 is slidably sleeved inside the first connecting plate 3. A guide rod 6 is fixedly connected to the surface of the second connecting plate 4. The guide rod 6 slides through the interior of the first connecting plate 3 and into the interior of the fixing rod 5. A positioning block 7 extending outwards is slidably sleeved inside the end of the guide rod 6 away from the second connecting plate 4. A first compression spring 8 is fixedly connected between the positioning block 7 and the inner wall of the inner groove of the guide rod 6. The surface of the fixing rod 5 is open... Several positioning slots 9 are provided, which are connected to the interior of the fixing rod 5. The positioning slots 9 and the positioning blocks 7 are adapted to each other. The surface of the first connecting plate 3 on the left is provided with a fine adjustment component, and the exterior of the two fixing half rings 2 is provided with a locking component. When the operator needs to connect the two corrugated pipe bodies 1, the fixing half rings 2 are first fitted onto the end of the corrugated pipe body 1 with the help of the locking component. Then, the guide rod 6 is slid into the interior of the first connecting plate 3 and slides into the interior of the fixing rod 5. Then the operator can push the rear corrugated pipe body 1 closer to the front corrugated pipe body 1. After moving to the approximate position, the two corrugated pipe bodies 1 can be initially fixed with the cooperation between the positioning block 7 and the positioning slots 9. Then, the position of the corrugated pipe bodies 1 can be precisely adjusted again with the help of the fine adjustment component.

[0024] In the above embodiment, the upper end of the positioning block 7 is provided with two inclined surfaces. When the guide rod 6 slides forward, the positioning block 7 will directly contact the inner wall of the positioning groove 9 through the front inclined surface, thereby realizing the automatic retraction of the positioning block 7. The rear side of the positioning block 7 will contact the inner wall of the positioning groove 9 through the vertical surface, thus preventing the guide rod 6 from being pulled backward. When the guide rod 6 needs to slide backward inside the fixed rod 5, the positioning block 7 is pressed to make its upper end flush with the upper surface of the fixed rod 5. Subsequently, during the backward movement of the guide rod 6, it will contact the positioning groove 9 with the rear inclined surface, ultimately realizing the separation of the fixed rod 5 and the guide rod 6.

[0025] The fine-tuning component includes a connecting block 10, which is fixedly connected to the lower surface of the left first connecting plate 3. A movable plate 11 is slidably connected to the lower surface of the left fixed rod 5. An adjusting screw 12 is rotatably connected between the movable plate 11 and the connecting block 10. The front end of the adjusting screw 12 rotates through the interior of the movable plate 11. A knob is also matched to the front end of the adjusting screw 12. A fixed plate 13 is fixedly connected to the lower surface of the left fixed rod 5. The fixed plate 13 is threaded onto the outside of the adjusting screw 12. By rotating the adjusting screw 12, the operator can drive the fixed plate 13 to move. The movement of the fixed plate 13 can drive the movement of the fixed rod 5. At this time, with the cooperation of the positioning block 7, the guide rod 6 will be pulled to move. The movement of the guide rod 6 can drive the movement of the fixed half ring 2, thereby realizing the slow approach of the two bellows bodies 1, thus achieving precise position adjustment.

[0026] The locking assembly includes a first mounting plate 14, which is fixedly connected to the surface of the left fixing half-ring 2. A second mounting plate 15 is fixedly connected to the surface of the right fixing half-ring 2. The second mounting plate 15 is hollow inside. Two guide grooves 16 are formed on the side of the second mounting plate 15 facing the first mounting plate 14. Two L-shaped connecting rods 17 are slidably connected inside the guide grooves 16. The L-shaped connecting rods 17 extend into the interior of the second mounting plate 15. Two through grooves 18 are formed inside the first mounting plate 14. The through grooves 18 and the L-shaped connecting rods 17 are adapted to each other. The mounting plate 15 is internally equipped with a reset component and an unlocking component. When the two fixing half-rings 2 are fixed, when the two fixing half-rings 2 are sleeved on the outside of the bellows body 1, the inclined surface of the L-shaped connecting rod 17 inside the second mounting plate 15 will contact the first mounting plate 14, thereby forcing the two L-shaped connecting rods 17 to move to both sides. After the L-shaped connecting rods 17 have completely entered the through groove 18, the L-shaped connecting rods 17 can be reset by means of the reset component, thereby hooking the first mounting plate 14 through the L-shaped connecting rods 17 to achieve the fixation of the two fixing half-rings 2.

[0027] The reset assembly includes a limiting rod 19, which is fixedly connected to a cavity inside the second mounting plate 15. Two L-shaped connecting rods 17 are slidably sleeved on the outside of the limiting rod 19. A second reset spring 20 is fixedly connected between the L-shaped connecting rods 17 and the inner wall of the second mounting plate 15. The second reset spring 20 is movably sleeved on the outside of the limiting rod 19. When the two L-shaped connecting rods 17 move to both sides, they will compress the second reset spring 20, thereby forcing the second reset spring 20 to undergo elastic deformation. Subsequently, the L-shaped connecting rods 17 can be reset by means of the second reset spring 20.

[0028] The unlocking component includes a cam 21, which is rotatably connected to the inside of the second mounting plate 15 via a shaft. The cam 21 is located between two L-shaped connecting rods 17. A torsion spring 22 is fixedly connected between the cam 21 and the inner wall of the second mounting plate 15. The torsion spring 22 is movably sleeved on the outside of the shaft of the cam 21. The shaft of the cam 21 rotates through the inside of the second mounting plate 15. By rotating the cam 21, the two L-shaped connecting rods 17 can be pushed to both sides. At this time, the torsion spring 22 will produce elastic deformation, thereby aligning the L-shaped connecting rods 17 with the through groove 18, so as to facilitate the subsequent separation of the fixing half ring 2.

[0029] A handle 23 is fixedly connected to the shaft of the cam 21. A sliding chamber is provided inside the handle 23. Two pressing plates 24 are slidably connected inside the handle 23. Both pressing plates 24 slide through the inside of the handle 23. Two friction plates 25 are provided on the outside of the handle 23. The friction plates 25 and the pressing plates 24 are fixedly connected to the shaft through which they slide.

[0030] The handle 23 also has a reset component inside. The two pressing plates 24 are slidably sleeved on the outside of the limiting rod 19 located inside the handle 23. The surface of the second mounting plate 15 is fixedly connected to the friction ring 26. When the operator needs to disassemble the fixed half ring 2, he first holds the handle 23. At this time, the operator will squeeze the two pressing plates 24. The sliding of the pressing plates 24 can drive the friction plate 25 to move. Afterwards, the friction plate 25 will no longer be pressed against the friction ring 26. Then, the operator can rotate the handle 23 to drive the cam 21 to rotate.

[0031] In the above embodiment, the internal reset component of the grip 23 ensures that the friction plate 25 is always pressed against the friction ring 26, thereby ensuring the stability of the grip 23 and preventing it from rotating. Furthermore, the stability of the grip 23 can be further improved with the help of the torsion spring 22.

[0032] Working principle:

[0033] When using this flexible corrugated pipe quick installation pretreatment device, firstly, two fixing half-rings 2 are sleeved on the outside of the corrugated pipe body 1. When the two fixing half-rings 2 are sleeved on the outside of the corrugated pipe body 1, the inclined surface of the L-shaped connecting rod 17 provided inside the second mounting plate 15 will contact the first mounting plate 14, thereby forcing the two L-shaped connecting rods 17 to move to both sides. When the two L-shaped connecting rods 17 move to both sides, they will squeeze the second return spring 20, thereby forcing the second return spring 20 to produce elastic deformation. After the L-shaped connecting rod 17 is completely inserted into the through groove 18, the L-shaped connecting rod 17 can be reset by the setting of the second return spring 20, thereby fixing the two fixing half-rings 2 by hooking the first mounting plate 14 through the L-shaped connecting rod 17.

[0034] Then, the guide rod 6 is slidably inserted into the interior of the first connecting plate 3 and slidably extended into the interior of the fixing rod 5. Then, the worker can push the rear corrugated pipe body 1 closer to the front corrugated pipe body 1. After moving to the approximate position, the two corrugated pipe bodies 1 can be initially fixed by the cooperation between the positioning block 7 and the positioning groove 9.

[0035] Then, by rotating the adjusting screw 12, the operator can move the fixing plate 13. The movement of the fixing plate 13 will then move the fixing rod 5. At this time, with the cooperation of the positioning block 7, the guide rod 6 will be pulled to move. The movement of the guide rod 6 will then move the fixing half ring 2, thereby allowing the two bellows bodies 1 to slowly approach each other, thus achieving precise position adjustment.

[0036] When it is necessary to disassemble the two fixed half-rings 2, first hold the handle 23. At this time, the worker will squeeze the two pressing plates 24. The sliding of the pressing plates 24 will drive the friction plate 25 to move. Subsequently, the friction plate 25 will no longer be pressed against the friction ring 26. Then, the worker can rotate the handle 23 to drive the cam 21 to rotate. The rotation of the cam 21 will push the two L-shaped connecting rods 17 to both sides. At this time, the torsion spring 22 will produce elastic deformation, thereby aligning the L-shaped connecting rods 17 with the through groove 18, so as to facilitate the subsequent separation of the fixed half-rings 2.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
