Description

Technical Field

[0001] This utility model relates to the field of pipeline processing equipment technology, and in particular to an expansion and repair device for communication pipelines. Background Technology

[0002] Optical communication cables are typically distributed to different geographical areas via ducts. These ducts provide the outermost layer of physical protection for the cables, ensuring their structural integrity. However, during actual construction, improper handling can cause external pressure to deform the ducts. To ensure the cables can pass through smoothly, it's often necessary to replace the ducts with new, intact ones. This inevitably leads to material waste and hinders efforts to reduce construction costs. Utility Model Content

[0003] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0004] An expansion and repair device for a communication pipeline includes a hydraulic cylinder and an expansion head. A detachable expansion head is located on one side of the hydraulic cylinder, where a telescopic rod is mounted. The inner diameter of the expansion head gradually decreases in the direction away from the hydraulic cylinder. The telescopic rod can pass through the expansion head, and its diameter is clearance-fitted with the end of the expansion head with the largest inner diameter.

[0005] Furthermore, the hydraulic cylinder is equipped with an oil pipe, and both ends of the oil pipe are equipped with quick connectors. The oil pipe is connected to the hydraulic cylinder and the external pressure testing equipment through the quick connectors.

[0006] Furthermore, the expansion head includes a conical head, a cylinder, and a flange. The two ends of the cylinder are connected to the flange and the conical head, respectively. The flange has multiple evenly spaced screws on its circumference, and the hydraulic cylinder has threaded holes for the matching screws.

[0007] Furthermore, the diameter of the conical head gradually decreases along the direction away from the cylinder, and the conical head has multiple evenly spaced openings in the circumferential direction.

[0008] Furthermore, the hydraulic cylinder is provided with a positioning groove for mating with the flange; the flange has multiple evenly spaced protrusions on its circumferential side, and the positioning groove is provided with positioning openings for mating with the protrusions.

[0009] Furthermore, the end of the telescopic rod that contacts the conical head is provided with a conical head.

[0010] Furthermore, the top of the hydraulic cylinder is equipped with a handle, and the bottom of the hydraulic cylinder is equipped with multiple symmetrically distributed support feet.

[0011] The beneficial effects of this invention are: the smaller inner diameter end of the expanding head facilitates insertion into the deformation area of ​​the pipe; driven by the telescopic rod, the expanding head produces uniform radial expansion, restoring the deformation area of ​​the pipe to its initial shape. Different models of expanding heads have different lengths and expansion diameters, and the detachable expanding head allows for easy replacement according to actual usage.

[0021] Please see Figures 1-3 A communication pipeline expansion and repair device includes a hydraulic cylinder 1 and an expansion head 2. The hydraulic cylinder 1 has a telescopic rod 14 on one side, and a detachable expansion head 2 is provided thereon. The inner diameter of the expansion head 2 gradually decreases in the direction away from the hydraulic cylinder 1. The telescopic rod 14 can pass through the expansion head 2, and the diameter of the telescopic rod 14 is clearance-fitted with the end of the expansion head 2 with the maximum inner diameter.

[0022] The hydraulic cylinder 1 is equipped with an oil pipe 11, and both ends of the oil pipe 11 are equipped with quick connectors 111. The oil pipe 11 is connected to the hydraulic cylinder 1 and external pressure testing equipment through the quick connectors 111, allowing the entire device to be quickly installed or disassembled onto the external pressure testing equipment. The top of the hydraulic cylinder 1 is equipped with a handle 12, and the bottom of the hydraulic cylinder 1 is equipped with multiple symmetrically distributed support feet 13. The operator can adjust the overall position of the device by operating the handle 12 to align it with the pipeline to be repaired. The support feet 13 help maintain the overall position of the device during the construction process.

[0023] Pressure testing equipment typically includes a manual pressure pump or other types of motorized pressure pumps. As the pressure pump injects hydraulic oil into the hydraulic pump, the telescopic rod 14 gradually passes through the expansion head 2. When the hydraulic cylinder 1 drives the telescopic rod 14 through the expansion head 2, radial pressure is generated on the inner wall of the expansion head 2, causing the expansion head 2 to undergo radial expansion deformation, thereby repairing the deformed communication pipeline.

[0024] The expander head 2 includes a conical head 23, a cylinder 22, and a flange 21. The two ends of the cylinder 22 are connected to the flange 21 and the conical head 23, respectively. The conical head 23, cylinder 22, and flange 21 are an integrated structure. Multiple evenly spaced screws 211 are provided on the circumference of the flange 21, and the hydraulic cylinder 1 has threaded holes 16 for engaging the screws 211. The screws 211 pass through the flange 21 and are screwed into the screw holes 211. The expander head 2 and the hydraulic cylinder 1 are detachably connected through the engagement of the screws 211 and the threaded holes 16. Different models of expander heads 2 have different lengths and expandable diameters. The detachable expander head 2 allows for replacement with different models according to different application scenarios, improving the applicability of the device.

[0025] The conical head 23 has a gradually decreasing diameter along the direction away from the cylinder 22, and multiple evenly spaced openings 231 are provided on its circumference. When the telescopic rod 14 passes through the conical head 23, it applies radial pressure to the conical head 23, causing the conical head 23 to expand radially. The evenly spaced openings 231 facilitate uniform radial deformation of the conical head 23 under the action of the telescopic rod 14. The end of the telescopic rod 14 that contacts the inner wall of the conical head 23 is provided with a cone 141. The cone 141 can increase the contact area between the telescopic rod 14 and the conical head 23, making the force uniform in all areas of the conical head 23, maintaining a consistent degree of deformation, and improving the expansion effect of the communication channel.

[0026] The hydraulic cylinder 1 is equipped with a positioning groove 15 that mates with the flange 21. The relative position of the expanding head 2 and the telescopic rod 14 can be quickly determined by the engagement of the positioning groove 15 and the flange 21. Multiple evenly spaced protrusions 212 are provided on the circumferential side of the flange 21, and the positioning groove 15 is equipped with positioning openings 151 that mate with the protrusions 212. The circumferential position of the expanding head 2 can be quickly determined by the engagement of the protrusions 212 and the positioning openings 151, allowing for the rapid assembly of the device.

[0027] The working principle of this utility model is as follows: The conical head 23 is inserted into the communication pipeline area to be repaired. Hydraulic oil is pumped into the hydraulic cylinder 1 along the oil pipe 11 by an external pressure device. The telescopic rod 14 gradually passes through the expanding head 2 and contacts the conical head 23. Under the action of the telescopic rod 14, the conical head 23 undergoes radial deformation and expands evenly in all directions. The communication pipeline is then forced to return to its original shape.

[0028] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
