Description

Technical Field

[0001] This utility model belongs to the field of municipal engineering technology, specifically relating to a correction device for pipeline construction. Background Technology

[0002] Pipeline straightening devices are used to correct deviations in pipelines during laying or installation to ensure installation quality and normal operation. During pipeline construction, various factors, such as uneven ground settlement and construction errors, may cause pipelines to bend or deviate. The straightening device straightens the bent parts by applying uniform pressure to the inner wall of the pipeline, maintaining good straightness, reducing internal resistance, and ensuring smooth fluid flow within the pipeline.

[0003] Some existing pipeline construction correction devices typically employ hydraulic jacks, screw and nut mechanisms, etc., to apply pressure to the outer wall of the pipeline. This external force causes the pipeline to shift and correct its position. However, applying pressure to the outer wall of the pipeline may cause uneven stress distribution inside the pipeline, especially in weak areas such as welds and joints. This may increase stress concentration, and over long-term use, these areas are prone to fatigue cracks, thereby reducing the overall safety and service life of the pipeline. Utility Model Content

Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0025] Example

[0026] Reference Figures 1-4 This is an embodiment of the present invention, which provides a pipeline construction correction device, comprising:

[0027] The supporting mechanism 100 includes a fixed plate 110, a support frame 120 fixedly connected to the outer surface of the fixed plate 110, a turntable 130 fixedly installed on the other side of the fixed plate 110 by bearings, and a handle block 140 fixedly installed on the outer surface of the support frame 120.

[0028] It should be noted that during pipeline alignment operations, the construction personnel use the hand-held block 140 to move the bearing mechanism 100 to a suitable position inside or around the pipeline, so that the device is aligned with the part of the pipeline that needs to be aligned. The fixed plate 110 and the support frame 120 are used to ensure the stability of the device, and the turntable 130 is used to rotate the straightening mechanism 200 to achieve the effect of omnidirectional alignment of the pipeline.

[0029] The straightening mechanism 200 includes an inner support assembly 210 for straightening the bent portion by supporting the inner wall of the pipe, which is located outside the turntable 130.

[0030] And a rotating mechanism 220, located outside the fixed plate 110, for controlling the rotation of the inner support assembly 210 so that all parts of the inner wall of the pipe can be effectively supported.

[0031] Specifically, the inner support assembly 210 includes a threaded rod 211 fixedly mounted on the inner surface of the support frame 120 via bearings, an inner threaded sleeve 212 threadedly connected to the outer surface of the threaded rod 211, a connecting post 213 fixedly mounted on the outer end face of the inner threaded sleeve 212 via bearings, pressure blocks 214 arranged in a circumferential array on the outer surface of the connecting post 213, a pressure receiving block 215 slidably sleeved on the outer surface of the pressure applying block 214, an opening and closing plate 216 fixedly connected to the outside of the pressure receiving block 215, a guide block 217 fixedly connected to the outer end face of the opening and closing plate 216, a guide rail 218 fixedly mounted on the outer surface of the turntable 130 and used in conjunction with the guide block 217, and a first handwheel 219 fixedly connected to the outer end face of the threaded rod 211.

[0032] It should be noted that when the construction worker turns the first handwheel 219, it can drive the threaded rod 211 to rotate. The inner threaded sleeve 212 moves axially along the surface of the threaded rod 211 through the cooperation with the limiting component 230, and then pushes the connecting column 213 and the pressure block 214 to move synchronously. Since the contact surface of the pressure block 214 and the pressure receiving block 215 is inclined, the pressure receiving block 215 can drive the opening and closing plate 216 and the guide block 217 to expand outward along the guide rail 218 under the push of the pressure block 214, so that the opening and closing plate 216 fits against the inner wall of the pipe and applies uniform pressure to the bent part of the pipe to achieve the effect of straightening the pipe.

[0033] Furthermore, the contact surfaces of the pressure block 214 and the pressure block 215 are both inclined surfaces, and the outer surface of the guide block 217 slides in contact with the outer surface of the guide rail 218.

[0034] Preferably, the rotating mechanism 220 includes a gear 221 fixedly sleeved on the outer surface of the turntable 130, a gear 222 meshing with the outer surface of the gear 221, a connecting rod 223 fixedly connected to the inner surface of the gear 222, and a second handwheel 224 fixedly connected to the through end of the connecting rod 223.

[0035] Furthermore, it should be noted that when the construction personnel turn the second handwheel 224, the gear 222 can be rotated through the connecting rod 223. The gear 222, in conjunction with the gear disc 221, drives the turntable 130 and the inner support assembly 210 mounted on it to rotate synchronously. This ensures that all parts of the inner wall of the pipe are effectively supported by the inner support assembly 210, thereby ensuring the uniformity and comprehensiveness of the correction.

[0036] It should be noted that the straightening mechanism 200 also includes a limiting mechanism 230 for limiting the internal threaded sleeve 212 to ensure that it can only move axially, which is located inside the support frame 120.

[0037] Furthermore, the limiting mechanism 230 includes a limiting groove 231 formed on the outer surface of the internal threaded sleeve 212, and a limiting rod 232 fixedly connected to the inner wall of the support frame 120 and used in conjunction with the limiting groove 231.

[0038] It should be explained that when the internal threaded sleeve 212 moves axially under the drive of the threaded rod 211, the rotation of the connecting column 213 is restricted by the cooperation of the limiting rod 232 and the limiting groove 231, thereby ensuring that the internal threaded sleeve 212 can only move axially.

[0039] Specifically, a rotating bearing sleeve is installed at the connection between the connecting rod 223 and the fixed plate 110, and the outer surface of the limiting rod 232 slides in contact with the inner wall of the limiting groove 231.

[0040] When in use, the construction worker holds the hand-held block 140 and moves the bearing mechanism 100 to a suitable position inside or around the pipe so that the device is aligned with the part of the pipe that needs to be corrected.

[0041] Next, turn the first handwheel 219 to drive the threaded rod 211 to rotate. The inner threaded sleeve 212 moves axially along the threaded rod 211 in cooperation with the limiting mechanism 230, thereby pushing the connecting column 213 and the pressure block 214 to move synchronously. Since the contact surface between the pressure block 214 and the pressure block 215 is inclined, the pressure block 215 is pushed by the pressure block 214 to drive the opening and closing plate 216 and the guide block 217 to expand outward along the guide rail 218, so that the opening and closing plate 216 fits against the inner wall of the pipe and applies uniform pressure to the bent part of the pipe to straighten it.

[0042] To ensure the uniformity and comprehensiveness of the correction: turn the second handwheel 224, which drives the gear 222 to rotate through the connecting rod 223. Through the cooperation between the gear 222 and the gear plate 221, the turntable 130 and the inner support assembly 210 installed on its surface rotate synchronously, so that all parts of the inner wall of the pipe can be effectively supported by the inner support assembly 210.

[0043] In summary, through the coordination of the various components in the straightening mechanism 200, pressure can be applied evenly to the curved parts of the pipe from the inner wall, avoiding uneven stress distribution inside the pipe caused by applying pressure to the outer wall, and preventing stress concentration at pipe welds or connections. This achieves the effect of effectively straightening the pipe while improving the overall safety and service life of the pipe.
