Description

Technical Field

[0001] This utility model relates to the field of breaking devices, and in particular to a device for breaking old pipes in pipeline replacement. Background Technology

[0002] In the process of urban infrastructure construction and upgrading, the replacement and repair of underground pipelines is a crucial project. With increasing service life, existing underground pipelines may become unusable due to corrosion, aging, and damage, necessitating replacement. Existing old pipe removal devices use pressure to burst concrete pipes. The device applies outward pressure to the inner wall of the concrete pipe; when the pressure exceeds the pipe's withstand limit, the old pipe ruptures, thus completing the removal. However, because the strength distribution of the concrete pipe may be uneven, the force at the pressure application point is difficult to precisely control during the bursting process, easily leading to inconsistent degrees of rupture. Some areas may not rupture completely, leaving large pipe fragments that hinder the subsequent laying of new pipes. Furthermore, the significant impact force generated during bursting may affect the surrounding soil and adjacent pipelines, causing soil loosening, settlement, and even damage to adjacent pipelines, increasing construction safety risks and subsequent repair costs. Therefore, this utility model proposes an old pipe removal device for pipeline replacement. Utility Model Content

[0003] The purpose of this invention is to address the problem in the prior art that the strength distribution of concrete pipes may be uneven, making it difficult to precisely control the force at the pressure point during the bursting process. This can easily lead to inconsistent degrees of rupture in old pipes, with some areas potentially failing to rupture completely and leaving large pipe fragments that hinder the subsequent laying of new pipes. Furthermore, the large impact force generated during bursting can affect the surrounding soil and adjacent pipes, causing soil loosening, settlement, and even damage to adjacent pipes, increasing construction safety risks and subsequent repair costs. The invention proposes a pipe replacement old pipe bursting device.

[0005] Optionally, the sliding assembly includes a locking block that is fixedly snapped to the outer wall of the support ring. One end of the locking block is fixedly connected to a fixed frame. A guide rod is fixedly arranged between the fixed frames. A set of sliding collars is movably sleeved on the outer wall of the guide rod. One end of the sliding collar is rotatably connected to a connecting rod. One end of the connecting rod is rotatably connected to a connecting plate. One end of the connecting plate is fixedly connected to a roller. A spring is sleeved on the outer wall of the guide rod. One end of the spring is fixedly connected to the fixed frame, and the other end of the spring is fixedly connected to the sliding collar.

[0006] Optionally, the pulverizing assembly includes a fixed ring, a guide groove is provided inside the fixed ring, a toothed ring is movably sleeved inside the guide groove, a fixed collar is fixedly sleeved on the outer wall of the toothed ring, and a plurality of pulverizing heads are provided on the fixed collar.

[0007] Optionally, the pulverizing assembly further includes a first motor fixedly disposed on one side of the fixed ring, the output end of the first motor being fixedly connected to a gear, the gear passing through the fixed ring and meshing with the gear ring.

[0008] Optionally, a plurality of guide grooves are provided on one side of the fixing collar, and a guide block is slidably disposed inside the guide groove, with one end of the guide block being fixedly connected to the grinding head.

[0010] In summary, this application includes at least one of the following beneficial technical effects:

[0011] This utility model achieves the telescopic adjustment of the crushing head through the guide groove on one side of the fixed collar in the crushing component, the internal sliding guide block, and the linkage rod structure driven by the second motor on the support frame, the threaded rod, the threaded sleeve block, the bearing, and the connecting block. The old pipe is first ground and pre-treated, and then crushed by pressure.

[0028] Example

[0029] like Figure 1 As shown, the pipe replacement and old pipe breaking device proposed in this utility model includes: two support rings 1, multiple support rods 2 fixedly arranged between the support rings 1, and at least three support rods 2 arranged in a ring array on the support rings 1, which can provide stable support for the support rings 1, and a fixing block 4 fixedly sleeved on the outer wall of the support rods 2, which can limit the crushing component 5 on the support rods 2.

[0030] As one implementation method, such as Figure 1 and Figure 2As shown, the outer wall of the support rod 2 is fixedly fitted with sliding components 3 for guiding the support ring 1. The sliding components 3 include a locking block 31 fixedly locked to the outer wall of the support ring 1. One end of the locking block 31 is fixedly connected to a fixing frame 32, and the fixing frame 32 is set with a "U" shaped structure. The locking block 31 can stably fix the fixing frame 32 to the support ring 1. A guide rod 33 is fixedly installed between the fixing frames 32. A set of sliding collars 34 is movably sleeved on the outer wall of the guide rod 33, which can make the sliding collars 34 move according to the direction of the guide rod 33. The sliding collar 34 moves in a stable manner. One end of the sliding collar 34 is rotatably connected to the connecting rod 35 via a shaft. One end of the connecting rod 35 is rotatably connected to the connecting plate 36 via a shaft, enabling them to move in tandem. One end of the connecting plate 36 is fixedly connected to the roller 37. A spring 38 is sleeved on the outer wall of the guide rod 33. One end of the spring 38 is fixedly connected to the fixed frame 32, and the other end of the spring 38 is fixedly connected to the sliding collar 34. The elastic force of the spring 38 can exert pressure on the roller 37, thereby making the roller 37 fit tightly against the inner wall of pipes of different diameters, thus improving the applicability.

[0031] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, a shredding assembly 5 for breaking up the pipe is provided between the fixed sleeve blocks 4. The shredding assembly 5 includes a fixed ring 501, a guide groove 502 is provided in the fixed ring 501, and a toothed ring 503 is movably sleeved inside the guide groove 502, which can make the toothed ring 503 rotate stably inside the guide groove 502. A fixed sleeve 504 is fixedly sleeved on the outer wall of the toothed ring 503. A plurality of shredding heads 505 are provided on the fixed sleeve 504, and the plurality of shredding heads 505 are arranged in a ring array on the fixed sleeve 504, which can make the toothed ring 503 drive the plurality of shredding heads 505 to rotate simultaneously through the fixed sleeve 504.

[0032] Furthermore, the pulverizing component 5 also includes a first motor 506 fixedly disposed on one side of the fixed ring 501. A gear 507 is fixedly connected to the output end of the first motor 506. The gear 507 passes through the fixed ring 501 and meshes with the gear ring 503, so that the gear 507 can be driven by the first motor 506 to drive the gear 507 to drive the gear ring 503 to rotate stably inside the guide groove 502.

[0033] Secondly, a plurality of guide grooves 508 are provided on one side of the fixed collar 504. A guide block 509 is slidably arranged inside the guide groove 508. The guide groove 508 and the guide block 509 are arranged in a "convex" shape, which enables the guide block 509 to slide stably inside the guide groove 508. One end of the guide block 509 is fixedly connected to the grinding head 505, which facilitates the adjustment of the length of the grinding head 505 extending on the fixed collar 504.

[0034] Furthermore, a support frame 510 is fixedly arranged between the fixed rings 501, and a second motor 511 is fixedly sleeved on the support frame 510, providing stable support for the second motor 511. A threaded rod 512 is fixedly arranged at the output end of the second motor 511, enabling the output end of the second motor 511 to drive the threaded rod 512 to rotate. A threaded sleeve block 513 is threadedly sleeved on the outer wall of the threaded rod 512, which can drive the threaded sleeve block 513 to move during the rotation of the threaded rod 512. A one-way bearing 5 is rotatably sleeved on the outer wall of the threaded sleeve block 513. 14. During the rotation of the threaded rod 512, the threaded sleeve block 513 will drive the one-way bearing 514 to move, but the one-way bearing 514 will not rotate. When the first motor 506 drives the gear ring 503 to rotate through the gear 507, multiple connecting blocks 515 are fixedly provided on the outer wall of the one-way bearing 514. One end of the connecting block 515 is rotatably connected to the linkage rod 516. One end of the linkage rod 516 is rotatably connected to the guide block 509. The gear ring 503 drives the one-way bearing 514 to rotate on the threaded sleeve block 513 through the linkage rod 516 and the connecting block 515.

[0035] In this embodiment, during the old pipe replacement operation, the old pipe replacement and breaking device is first inserted into the port of the old pipe. At this time, the locking block 31 is fixed to the outer wall of the support ring 1. As the device enters the old pipe, the inner wall of the old pipe will squeeze the roller 37. The pressure is transmitted to the connecting rod 35 through the connecting plate 36, causing the sliding collar 34 to move along the guide rod 33 towards the fixed frame 32, while the spring 38 is compressed. The reaction force of the spring 38 will push the sliding collar 34 to move in the opposite direction, driving the connecting rod 35 and the connecting plate 36 to adjust the position of the roller 37, so that the roller 37 fits tightly against the inner wall of the old pipe of different thicknesses. Through the coordinated action of multiple sets of rollers 37, the device can be stably positioned in the center of the old pipe, ensuring the accuracy of subsequent operations.

[0036] When the device moves inside the old pipe, the spring 38 of the sliding component 3 continuously adjusts the tension of the roller 37 according to the change of the inner diameter of the old pipe, so that the device can move smoothly inside old pipes of various specifications.

[0037] Upon reaching the work position, the old pipe undergoes pre-treatment by grinding. The second motor 511 on the support frame 510 starts, and its output drives the threaded rod 512 to rotate. The threaded sleeve block 513 moves axially along the outer wall of the threaded rod 512, driving the linkage rod 516 through the one-way bearing 514 and the connecting block 515. This causes the guide block 509 to slide in the guide groove 508 on one side of the fixed collar 504, thereby adjusting the extension length of the grinding head 505. At this time, the grinding head 505 is set to extend to a shorter length. The first motor 506 starts, and the gear 507 at the output drive the gear ring 503 to rotate in the guide groove 502 of the fixed ring 501. The fixed collar 504 rotates synchronously with the gear ring 503, and the grinding head 505 grinds the inner wall of the old pipe evenly. After grinding, the grinding assembly 5 is moved to the next grinding position by the sliding component 3 to grind the areas of the old pipe's inner wall that need to be broken.

[0038] After grinding, the sliding assembly 3 is activated again to move the crushing assembly 5 to the grinding position. The second motor 511 is then activated, and its output drives the threaded rod 512 to rotate. This causes the threaded sleeve block 513 to move, which in turn moves the linkage rod 516, allowing the guide block 509 to slide further along the guide groove 508. This increases the extension length of the crushing head 505, allowing it to apply pressure to the ground old pipe, thus causing it to break. Because of the pre-treatment grinding, the old pipe has a more uniform strength distribution, and the degree of breakage is controllable under the action of the crushing head 505, avoiding incomplete breakage due to uneven strength.

[0039] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
