Description

Technical Field

[0001] This invention relates to the field of angle measurement, and more particularly to a positioning and measuring device for pipe jacking construction. Background Technology

[0002] Pipe jacking technology utilizes jacking force and the weight of the pipe itself to propel the pipeline through obstacles such as soil, rock, rivers, roads, and buildings. It eliminates the need for extensive surface excavation, making it a highly efficient and environmentally friendly pipeline construction method. Laser positioning and measurement devices used in pipe jacking construction guide and monitor the position and attitude of the pipe jacking machine during underground excavation, ensuring that the construction is carried out precisely according to design requirements.

[0003] Existing positioning and measurement facilities require constant adjustments when detecting the direction of pipe jacking, so that the detection facilities can correspond to the direction of the pipe itself and the direction of pipe jacking before the pipe jacking direction can be detected. The adjustment process is quite cumbersome, making the detection inconvenient. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the prior art by proposing a positioning and measuring device for pipe jacking construction.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a positioning and measuring device for pipe jacking construction, comprising a working well and a pipe body installed through the lower side of the working well. A flipping component is installed on the inner side of the working well, and a central frame is connected to the end of the flipping component. The axis of the central frame is aligned with the center point of one end of the pipe body. A centering frame is coaxially arranged at the other end of the pipe body. Multiple inclined frames are arranged in a circular array on the outer side of the central frame. The inclined frames are attached to the inner edge of one end of the pipe body. Multiple wheel frames are arranged in a circular array on the outer side of the centering frame. Centering wheels are installed at both ends of the wheel frames. The centering wheels are attached to the inner wall of the pipe body. A detection component is installed at the end of the central frame.

[0006] Preferably, the flipping component includes a mounting base fixedly installed on the inner side of the working well, the mounting base being located above the pipe body, a flipping shaft being rotatably mounted through the interior of the mounting base, a flipping frame being inlaid on the outer surface of the flipping shaft, the end of the flipping frame being fixed to the central frame, a servo motor being fixedly installed at the rear end of the flipping shaft, a motor frame being fixedly installed at the upper end of the servo motor, and the end of the motor frame being fixed to the mounting base.

[0007] Preferably, a No. 1 threaded sleeve is screwed onto the outer surface of the central frame, a No. 1 collar is coaxially rotatably mounted on the outer surface of the No. 1 threaded sleeve, and a plurality of No. 1 adjusting frames are rotatably mounted in a ring array on the outer surface of the No. 1 collar. A No. 1 frame column is rotatably mounted at the end of each of the plurality of No. 1 adjusting frames, and the end of the No. 1 frame column is fixed to the inclined fixed frame.

[0008] Preferably, a first column shell is fitted to the outer surface of the first column, and the end of the first column shell is fixed to the central frame. Two first protruding ridges extend symmetrically from the outer surface of the first column, and the first protruding ridges fit through the inner surface of the first column shell. A second threaded sleeve is screwed onto the outer surface of the centering frame. A second collar is rotatably mounted on the outer surface of the second threaded sleeve. Multiple second adjusting frames are rotatably mounted in a circular array on the outer surface of the second collar. A second column is rotatably mounted at the end of the second adjusting frame, and the end of the second column is fixed to the wheel frame.

[0009] Preferably, a second column shell is fitted to the outer surface of the second column, the end of the second column shell is fixed to the centering frame, and two second protruding ridges extend symmetrically from the outer surface of the second column. The second protruding ridges fit through the inner surface of the second column shell, and a first notch is opened on the side of the second column shell and the side of the first column shell.

[0010] Preferably, the detection component includes a bearing ring installed at the end of the central frame, a detection column is fitted inside the bearing ring, the upper and lower ends of the detection column extend through the upper and lower ends of the bearing ring, a laser emitter is fixedly installed at the upper end of the detection column, the laser emitter corresponds to the center line of the central frame, a pointer extends from the lower edge of the side of the detection column, and an angle plate is provided below the bearing ring at the end of the central frame, the pointer corresponds to the angle plate.

[0011] Preferably, the centerline of the angle plate is collinear with the centerline of the detection column, a ring frame is fixedly installed on the side of the bearing ring and the side of the angle plate, the end of the ring frame is fixed to the center frame, two limiting rings are coaxially embedded on the outer surface of the detection column, the two limiting rings are respectively attached to the upper and lower ends of the bearing ring, and a cross detection frame is fixedly installed on the end face of the centering frame, the midpoint of the cross detection frame is collinear with the centerline of the centering frame.

[0012] Preferably, both the front and rear ends of the bearing ring have protruding ears, and a guide post is slidably installed through the end of the protruding ear. A clamp is fixedly installed at the end of the guide post. The clamp slides through the outer surface of the bearing ring and is pressed against the outer surface of the detection post. A clamping spring is wound around the outside of the guide post, and the two ends of the clamping spring are fixed to the clamp and the protruding ear, respectively.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. Place the centering frame directly into the tube. At this time, the centering wheels on the multiple wheel frames of the ring array will roll against the inner wall of the tube, moving the centering frame to one end of the tube and aligning it with the midpoint of that end. Then, place the center frame at the other end of the tube. At this time, the multiple inclined frames of the ring array will be against the inner edge of the other end of the tube, aligning the center frame with the midpoint of the other end of the tube. Then, by emitting a laser through a laser emitter and observing whether it corresponds to the midpoint of the cross detection frame, the direction can be determined. The detection process does not require frequent adjustments to the detection equipment, effectively improving the convenience of detection.

[0014] 2. By rotating the No. 2 threaded sleeve, multiple No. 2 adjusting frames can be driven to move synchronously, causing the No. 2 frame column to slide within the No. 2 column housing, allowing multiple wheel frames to move synchronously. This allows for adjustment of the spacing between the multiple wheel frames to accommodate pipes of different diameters. Similarly, rotating the No. 1 threaded sleeve drives multiple No. 1 adjusting frames to move synchronously, causing the No. 1 frame column to slide within the No. 1 column housing, allowing multiple inclined fixed frames to move synchronously. This allows for adjustment of the spacing between the multiple inclined fixed frames to accommodate pipes of different diameters, thus meeting the testing requirements.

[0015] 3. The working servo motor can drive the rotating shaft to rotate, which in turn drives the rotating frame to rotate upward, so as to flip up the central frame and other components, so that the pipe jacking construction will not be obstructed by the central frame and other components, thereby ensuring the normal progress of the pipe jacking construction operation.

Detailed Implementation

[0018] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0019] like Figures 1-7 The illustrated positioning and measuring device for pipe jacking construction includes a working well 1 and a pipe body 2 installed through the lower side of the working well 1. The working well 1 facilitates pipe jacking construction. A flipping component is installed on the inner side of the working well 1, and a central frame 4 is connected to the end of the flipping component. The central frame 4 supports the inclined fixing frames 10. The axis of the central frame 4 is aligned with the center point of one end of the pipe body 2. A centering frame 3 is coaxially arranged at the other end of the pipe body 2. Multiple inclined fixing frames 10 are arranged in a circular array on the outer side of the central frame 4. The inclined fixing frames 10 can adapt to... The inner edge of one end of the tube body 2 allows the center frame 4 to be quickly positioned and aligned with the center point of one end of the tube body 2. The inclined frame 10 is attached to the inner edge of one end of the tube body 2. Multiple wheel frames 17 are arranged in a circular array on the outer side of the center frame 3. Centering wheels 18 are installed at both ends of the wheel frames 17. The wheel frames 17 serve to support the centering wheels 18. The centering wheels 18 are attached to the inner wall of the tube body 2. The centering wheels 18 can be attached to the inner wall of the tube body 2, so that the center frame 3 can be quickly positioned and aligned with the center point of the other end of the tube body 2. The end of the center frame 4 is equipped with a detection element.

[0020] The flipping component includes a mounting base 13 fixedly installed on the inner side of the working well 1. The mounting base 13 is located above the pipe body 2 and serves as the mounting base. A flipping shaft 16 is rotatably mounted through the interior of the mounting base 13. A flipping frame 5 is embedded on the outer surface of the flipping shaft 16. The flipping shaft 16 can support the flipping frame 5. The end of the flipping frame 5 is fixed to the center frame 4. A servo motor 15 is fixedly installed at the rear end of the flipping shaft 16. The servo motor 15 can drive the flipping frame 5 to rotate and flip. A motor frame 14 is fixedly installed at the upper end of the servo motor 15. The motor frame 14 serves to fix the servo motor 15. The end of the motor frame 14 is fixed to the mounting base 13.

[0021] A threaded sleeve 6 is screwed onto the outer surface of the center frame 4. A collar 7 is coaxially mounted on the outer surface of the threaded sleeve 6. The collar 7 serves to support the adjusting frame 8 and ensure the normal rotation of the threaded sleeve 6. Multiple adjusting frames 8 are rotatably mounted in a ring array on the outer surface of the collar 7. A support column 34 is rotatably mounted at the end of each adjusting frame 8. The adjusting frame 8 pushes the support column 34. The end of the support column 34 is fixed to the inclined frame 10.

[0022] A first column shell 9 is fitted to the outer surface of the first column 34. The end of the first column shell 9 is fixed to the central frame 4. The first column shell 9 serves to guide the first column 34. Two first protruding ribs 35 extend symmetrically from the outer surface of the first column 34. The first protruding ribs 35 fit and penetrate the inner surface of the first column shell 9. The first protruding ribs 35 prevent the first column 34 from rotating. Rotating the first threaded sleeve 6 drives multiple first adjusting frames 8 to move synchronously, thereby causing the first column 34 to slide in the first column shell 9, allowing multiple inclined fixed frames 10 to move synchronously, thereby adjusting the spacing between the multiple inclined fixed frames 10. Adjustments are made to accommodate pipes 2 of different diameters. A second threaded sleeve 22 is screwed onto the outer surface of the centering frame 3. A second collar 21 is coaxially mounted on the outer surface of the second threaded sleeve 22. The second collar 21 serves to support the second adjusting frame 20 and ensure the normal rotation of the second threaded sleeve 22. Multiple second adjusting frames 20 are rotatably mounted in a ring array on the outer surface of the second collar 21. A second frame column 37 is rotatably mounted at the end of the second adjusting frame 20. The second adjusting frame 20 pushes the second frame column 37. The end of the second frame column 37 is fixed to the wheel frame 17.

[0023] A second column shell 19 is fitted to the outer surface of the second column 37. The end of the second column shell 19 is fixed to the centering frame 3. The second column shell 19 serves to guide the second column 37. Two second protruding ribs 36 extend symmetrically from the outer surface of the second column 37. The second protruding ribs 36 fit and penetrate the inner surface of the second column shell 19. The second protruding ribs 36 prevent the second column 37 from rotating. A first notch 30 is opened on the side of the second column shell 19 and the side of the first column shell 9. The first notch 30 ensures that the connection between the second column 37 and the second adjusting frame 20, as well as the connection between the first adjusting frame 8 and the first column 34, will not be obstructed. Rotating the second threaded sleeve 22 can drive multiple second adjusting frames 20 to move synchronously, thereby driving the second column 37 to slide inside the second column shell 19, allowing multiple wheel frames 17 to move synchronously, so as to adjust the spacing between the multiple wheel frames 17 to accommodate pipes 2 of different diameters.

[0024] The detection component includes a bearing ring 26 installed at the end of the center frame 4. A detection column 24 is fitted inside the bearing ring 26, which supports the detection column 24. The upper and lower ends of the detection column 24 extend through the upper and lower ends of the bearing ring 26. A laser emitter 11 is fixedly installed at the upper end of the detection column 24, which corresponds to the center line of the center frame 4 and detects deviation. A pointer 32 extends from the lower edge of the side of the detection column 24. An angle plate 12 is provided below the bearing ring 26 at the end of the center frame 4. The pointer 32 and the angle plate 12 measure the deviation angle. The pointer 32 corresponds to the angle plate 12.

[0025] The centerline of the angle plate 12 is collinear with the centerline of the detection column 24. A ring frame 33 is fixedly installed on the side of the bearing ring 26 and the side of the angle plate 12. The end of the ring frame 33 is fixed to the center frame 4. The ring frame 33 serves to fix the bearing ring 26 and the angle plate 12. Two limiting rings 25 are coaxially embedded on the outer surface of the detection column 24. The two limiting rings 25 are respectively attached to the upper and lower ends of the bearing ring 26. The limiting rings 25 serve to prevent the bearing ring 26 and the detection column 24 from separating. A cross detection frame 23 is fixedly installed on the end face of the centering frame 3. The midpoint of the cross detection frame 23 is collinear with the centerline of the centering frame 3. The cross detection frame 23 can easily and quickly identify whether the laser line of the laser emitter 11 is aligned with the midpoint of the centering frame 3.

[0026] Both ends of the bearing ring 26 have protruding ears 28. A guide post 29 is slidably installed through the end of the protruding ear 28. The protruding ear 28 serves to support the guide post 29. A clamp 27 is fixedly installed at the end of the guide post 29. The clamp 27 slides through the outer surface of the bearing ring 26. The guide post 29 serves to guide the clamp 27. The clamp 27 is pressed against the outer surface of the detection post 24. The clamp 27 can clamp onto the detection post 24, so that the laser emitter 11 will not move on its own when there is no external force. A clamping spring 31 is wound around the outside of the guide post 29. The two ends of the clamping spring 31 are fixed to the clamp 27 and the protruding ear 28 respectively. The clamping spring 31 serves to press the clamp 27 against the surface.

[0027] In use, the center frame 4 is placed at the end of the tube body 2. At this time, the multiple inclined frames 10 of the ring array are attached to the inner edge of the end of the tube body 2, aligning the center frame 4 with the midpoint of the end of the tube body 2, that is, aligning the laser emitter 11 with the jacking direction of the tube body 2. Observe the position of the mounting base 13 in the working well 1, and fix the mounting base 13 in the working well 1 with expansion bolts. When jacking is required, the servo motor 15 works to drive the rotating shaft 16 to rotate, thereby driving the rotating frame 5 to rotate, so that the center frame 4 and other components can be flipped up, and then the tube body 2 can be inserted for jacking. When inspection is required after jacking, the centering frame 3 is directly placed into the tube body 2. At this time, the centering wheels 18 on the multiple wheel frames 17 of the ring array will roll against the inner wall of the tube body 2, moving the centering frame 3 to the inner edge of the tube body 2. At the end, and aligned with the midpoint of the end of the tube body 2, the centering frame 3 moves away from the working well 1. Then, the servo motor 15 reverses its operation to drive the center frame 4 to flip down, aligning the laser emitter 11 with the jacking direction of the tube body 2. The working well 1 then emits a laser, and the position of the laser on the cross detection frame 23 is observed. If the laser corresponds to the midpoint of the cross detection frame 23, it indicates that the jacking direction is not deviated. If the laser deviates from the midpoint of the cross detection frame 23, it indicates that the jacking direction is deviated. At this time, the laser emitter 11 can be rotated, which in turn drives the pointer 32 on the detection column 24 to rotate, so that the pointer 32 can move along the angle plate 12, allowing the laser to correspond to the midpoint of the cross detection frame 23. At this time, the angle indicated by the pointer 32 on the angle plate 12 can be observed to detect the deviation angle value of the jacking direction.
