Description

Technical Field

[0001] This solution belongs to the field of measurement auxiliary equipment, specifically involving a construction measurement device that facilitates pipeline positioning and laying. Background Technology

[0002] Currently, positioning and laying surveying in pipeline construction mainly relies on traditional surveying instruments, such as total stations and levels. The common operating method is as follows: surveyors first set up control points near the pipeline, then use instruments to aim at a prism or ordinary ruler placed at the pipeline opening, and through multiple measurements and manual calculations, they deduce the actual position of the pipeline center, and then direct the construction personnel to repeatedly adjust the pipeline's posture.

[0003] A search revealed that patent application CN115200456A discloses a positioning and measuring device for pipeline engineering surveying, comprising: a fixed frame; a support device connected to the fixed frame; a first positioning component connected to the support device; and a measuring device connected to the support device. The measuring device includes: a drive adjustment device connected to the fixed frame; and a second positioning component, one end of which is connected to the drive adjustment device.

[0004] In existing technologies, the support frame for the prism or ruler is usually independent of the pipe, resulting in an eccentricity error between its center and the actual central axis of the pipe. This error is difficult to measure and eliminate precisely, directly affecting the final positioning accuracy. To address this issue, some auxiliary positioning devices have emerged on the market, such as using simple clamps or brackets to fix the measuring target to the pipe. However, these devices often suffer from poor versatility, unstable clamping, or limited adjustment functions. They are difficult to quickly adapt to pipes of different diameters, are prone to loosening after clamping, and lack a convenient and precise fine-tuning mechanism to ensure accurate alignment between the target center and the pipe center. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this solution is to provide a construction surveying device that facilitates pipeline positioning and laying, in order to solve the problems of poor applicability and inaccurate positioning of existing auxiliary positioning devices for pipeline positioning and laying.

[0006] To achieve the above objectives, this solution provides a construction surveying device for easy pipeline positioning and laying, including an adjusting seat. A bidirectional screw is mounted inside the adjusting seat via bearings. The bidirectional screw penetrates the adjusting seat. Two moving blocks are threadedly connected to the outer side of the bidirectional screw. These moving blocks are slidably connected to the inside of the adjusting seat. A sleeve is fixedly connected to the bottom of each moving block. A locking mechanism is provided between the bidirectional screw and the adjusting seat. A base plate is fixedly connected to the top of the adjusting seat. Hollow shells are fixedly connected to the four corners of the upper end of the base plate. The interior of the hollow shells... A slidable inclined block is provided, and a sliding column is fixedly connected to the upper end of the inclined block. The sliding column penetrates the hollow shell and is slidably connected to the hollow shell. A fixing plate is fixedly connected to the top of the sliding column, and a mounting screw sleeve is fixedly connected to the middle of the upper end of the fixing plate. A screw head is threadedly connected to the mounting screw sleeve, and a laser target is fixedly connected to the top of the screw head. An adjusting rod is threadedly connected to the side wall of the hollow shell, and the adjusting rod penetrates the hollow shell. A round knob is fixedly connected to one end of the adjusting rod, and an I-beam is rotatably connected to the other end of the adjusting rod. The I-beam is slidably connected to the inclined part of the inclined block.

[0007] The principle of this solution is as follows: First, the equipment is placed above the end of the pipe to be laid or on the existing reference pipe. The operator rotates the rotating wheel, which in turn drives the bidirectional screw to rotate inside the adjusting seat. Since the threads on the bidirectional screw are opposite, the two moving blocks connected to it by the threads move towards or away from each other in the adjusting seat. The clamps at the bottom of the moving blocks move accordingly until they firmly clamp the outer wall of the pipe from both sides. Through this structure, the equipment can quickly adapt to and be fixed on pipes of different diameters. Moreover, before rotating the bidirectional screw by the rotating wheel, the locking pin is pulled by the lever, which disengages the locking pin from the locking disc on the bidirectional screw, thereby releasing the restriction on the bidirectional screw. When the clamp is adjusted to the correct position, the lever can be released, and the locking pin will reset under the action of the spring and re-insert into the corresponding locking hole on the locking disc. This effectively prevents the bidirectional screw from loosening due to accidental collisions or vibrations, ensuring the reliability of the measurement reference. After the equipment is fixed, the center of the laser target needs to be aligned with the actual central axis of the pipeline. First, a preliminary coarse adjustment of the target can be made by using the threaded engagement of the mounting sleeve and the screw head. Then, precise fine adjustments can be made by manually rotating the round knobs at the ends of the four adjusting rods. The rotation of the adjusting rods will push the I-beam blocks at their ends forward. The I-beam blocks and the inclined plane blocks slide against each other, thereby converting the horizontal thrust into vertical displacement, raising or lowering the inclined plane blocks. The inclined plane blocks drive the fixed plate above and the entire target assembly to rise or fall through the sliding column. Since each of the four corner hollow shells has an independent fine adjustment mechanism, the staff can precisely adjust the height of each corner of the target platform, thereby achieving precise centering of the target. Once the center of the laser target is precisely adjusted to be consistent with the central axis of the pipeline, the equipment can serve as a stable measurement reference point. External measuring instruments such as total stations can be aimed at this laser target to perform a series of construction measurement tasks such as pipeline axis positioning and slope control, thereby guiding the subsequent precise laying and connection of the pipeline.

[0008] The technical advantages of this solution are as follows: by driving the moving block and the jacket to move synchronously in opposite directions or back to back by rotating the bidirectional screw, it can quickly adapt to and firmly clamp onto the outer wall of pipes of different diameters, realizing rapid installation and positioning of the equipment. Moreover, the support structure formed by the adjusting seat and the jacket is stable, effectively avoiding errors caused by equipment displacement during the measurement process, effectively improving the accuracy of pipe axis and slope measurement, and laying a reliable foundation for subsequent precise pipeline laying.

[0009] By rotating the adjusting rods on the side walls of each hollow shell, the I-beam and inclined block are pushed to slide on their inclined surfaces, thereby precisely raising or lowering the sliding column and the fixed plate, ultimately achieving fine-tuning of the laser target height. This structure is easy to operate and can quickly calibrate the target center to the pipe center position, effectively eliminating the influence of pipe diameter changes on the measurement benchmark, ensuring the accuracy of laser beam centering and elevation control, and greatly improving construction efficiency.

[0010] Furthermore, a rotating wheel, made of stainless steel, is fixedly connected to one end of the bidirectional screw located outside the adjusting seat. The rotating wheel facilitates the rotation of the bidirectional screw.

[0011] Furthermore, ball bearings are provided on both the left and right sides of the inclined block, and these ball bearings are slidably connected to the inner wall of the hollow shell. The ball bearings reduce the relative friction between the inclined block and the hollow shell.

[0012] Furthermore, a linkage ball is fixedly connected to the I-beam block, and the linkage ball is slidably connected to the inclined block. A corresponding ball groove is formed on the inclined surface of the inclined block, and the linkage ball is located within the ball groove, thus enabling linkage between the I-beam block and the inclined block.

[0013] Furthermore, the locking mechanism includes a locking disc fixedly connected to the bidirectional screw rod body. A mounting shell is fixedly connected to the right side of the adjusting seat. A locking pin is slidably connected to the right side wall of the mounting shell. The locking pin passes through the mounting shell and is slidably connected to it. The locking pin is inserted into the locking disc. A lever is fixedly connected to the pin body of the locking pin. The lever passes through the mounting shell and is slidably connected to it. Through the locking mechanism, the bidirectional screw used to adjust the distance between the two sleeves is locked and prevented from loosening.

[0014] Furthermore, a guide rod is fixedly connected to the inner wall of the mounting housing. The guide rod is slidably connected to the locking pin. A spring is installed inside the locking pin. One end of the spring is fixedly connected to the guide rod, and the other end of the spring is fixedly connected to the inner surface of the locking pin. The guide rod and spring provide guidance for the extension and retraction of the locking pin.

[0015] Furthermore, a magnetic ring is fixedly connected to the locking pin, and the magnetic ring is attracted to the inner wall of the mounting housing. The magnetic ring helps to prevent the locking pin from loosening. Attached Figure Description

[0018] The basic implementation examples are as follows: Figures 1-3The diagram shows a construction surveying device for facilitating pipeline positioning and laying. It includes an adjusting base 1, with a bidirectional screw 2 mounted inside the adjusting base 1 via bearings. The bidirectional screw 2 penetrates the adjusting base 1. Two moving blocks 3 are threadedly connected to the outer side of the screw 2, and the moving blocks 3 are slidably connected inside the adjusting base 1. A sleeve 4 is fixedly connected to the bottom of each moving block 3. A rotating wheel 5, made of stainless steel, is fixedly connected to one end of the bidirectional screw 2 located outside the adjusting base 1. The rotating wheel 5 facilitates the rotation of the bidirectional screw 2.

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a base plate 101 is fixedly connected to the top of the adjusting seat 1. Hollow shells 7 are fixedly connected to the four corners of the upper end of the base plate 101. Inclined blocks 8 are slidably connected inside the hollow shells 7. Ball bearings 14 are provided on both the left and right sides of the inclined blocks 8. The ball bearings 14 are slidably connected to the inner wall of the hollow shells 7. By setting the ball bearing 14, the relative friction between the inclined block 8 and the hollow shell 7 can be reduced. The upper end of the inclined block 8 is fixedly connected to the sliding column 9, which penetrates the hollow shell 7 and is slidably connected to it. The top of the sliding column 9 is fixedly connected to the fixing plate 10. The middle of the upper end of the fixing plate 10 is fixedly connected to the mounting sleeve 11. The mounting sleeve 11 is connected to the screw head 12 by thread. The top of the screw head 12 is fixedly connected to the laser target 13. The side wall of the hollow shell 7 is connected to the adjusting rod 15 by thread. The adjusting rod 15 penetrates the hollow shell 7. One end of the adjusting rod 15 is fixedly connected to the round button 16. The other end of the adjusting rod 15 is rotatably connected to the I-shaped block 17. The I-shaped block 17 is slidably connected to the inclined part of the inclined block 8. The I-shaped block 17 is fixedly connected to the linkage ball 18, which is slidably connected to the inclined block 8. The inclined surface of the inclined block 8 is provided with a corresponding ball groove, and the linkage ball 18 is located in the ball groove, so that the I-shaped block 17 and the inclined block 8 can be linked.

[0020] like Figure 3 , Figure 5As shown, a locking mechanism 6 is provided between the bidirectional screw 2 and the adjusting seat 1. The locking mechanism 6 secures the bidirectional screw 2, which is used to adjust the distance between the two sleeves 4, preventing loosening. The locking mechanism 6 includes a locking disc 61 fixedly connected to the body of the bidirectional screw 2. A mounting shell 62 is fixedly connected to the right side of the adjusting seat 1. A locking pin 63 is slidably connected to the right side wall of the mounting shell 62, penetrating the mounting shell 62 and slidably connected to it. The locking pin 63 is inserted into the locking disc 61. A lever 67 is fixedly connected to the pin of the locking pin 63, penetrating the mounting shell 62 and slidably connected to it. A guide rod 64 is fixedly connected to the inner wall of the mounting shell 62, slidably connected to the locking pin 63. A spring 65 is provided inside the locking pin 63, with one end fixedly connected to the guide rod 64 and the other end fixedly connected to the inner surface of the locking pin 63. The guide rod 64 and spring 65 guide the extension and retraction of the locking pin 63. A magnetic ring 66 is fixedly connected to the pin body of the locking pin 63, and the magnetic ring 66 is attracted to the inner wall of the mounting shell 62. The magnetic ring 66 also helps to prevent the locking pin 63 from loosening.

[0021] The specific implementation process of this utility model is as follows: First, the equipment is placed above the end of the pipe to be laid or on the already laid reference pipe. The operator rotates the rotating wheel 5, which in turn drives the bidirectional screw 2 to rotate inside the adjusting seat 1. Since the threads on the bidirectional screw 2 are opposite, the two moving blocks 3 connected to it by the threads move towards or away from each other in the adjusting seat 1. The clamp 4 at the bottom of the moving block 3 moves accordingly until it firmly clamps the outer wall of the pipe from both sides. Through this structure, the equipment can quickly adapt to and be fixed on pipes of different diameters. Moreover, before rotating the bidirectional screw 2 by the rotating wheel 5, the locking pin 63 is pulled by the lever 67, so that the locking pin 63 is disengaged from the locking disc 61 on the bidirectional screw 2, thereby releasing the restriction on the bidirectional screw 2. When the clamp 4 is adjusted to the position, the lever 67 can be released, and the locking pin 63 will be reset under the action of the spring 65 and re-inserted into the corresponding locking hole on the locking disc 61. This effectively prevents the bidirectional screw 2 from loosening due to accidental collision or vibration, ensuring the reliability of the measurement reference. After the equipment is fixed, the center of the laser target 13 needs to be aligned with the actual central axis of the pipeline. First, a preliminary coarse adjustment of the target can be made by using the threaded engagement of the mounting sleeve 11 and the screw head 12. Subsequently, a precise fine adjustment can be made by manually rotating the round knob 16 at the end of the four adjusting rods 15. The rotation of the adjusting rods 15 will push the I-beam block 17 at its end to move forward. The I-beam block 17 slides with the inclined surface of the inclined block 8, thereby converting the horizontal thrust into vertical displacement, raising or lowering the inclined block 8. The inclined block 8 drives the upper part of the inclined block 8 through the sliding column 9. The fixed plate 10 and the entire target assembly are raised and lowered. Since each of the four hollow shells 7 at the four corners is independently equipped with a fine-tuning mechanism, the staff can precisely adjust the height of each corner of the target platform to achieve accurate centering of the target. When the center of the laser target 13 is precisely adjusted to be consistent with the central axis of the pipeline, the device can serve as a stable measurement reference point. External measuring instruments such as total stations can aim at the laser target 13 to perform a series of construction measurement tasks such as pipeline axis positioning and slope control, thereby guiding the subsequent accurate laying and connection of the pipeline.

[0022] This solution uses a rotating bidirectional screw 2 to drive the moving block 3 and the clamp 4 to move synchronously in opposite directions or in opposite directions. This allows for quick adaptation and secure clamping onto the outer wall of pipes of different diameters, enabling rapid installation and positioning of the equipment. Furthermore, the support structure formed by the adjusting seat 1 and the clamp 4 is stable, effectively avoiding errors caused by equipment displacement during the measurement process. This significantly improves the accuracy of pipe axis and slope measurements, laying a reliable foundation for subsequent precise pipe laying.

[0023] By rotating the adjusting rods 15 on the side walls of each hollow shell 7, the I-beam block 17 and the inclined block 8 are pushed to slide on their inclined surfaces, thereby precisely raising or lowering the sliding column 9 and the fixed plate 10, ultimately achieving fine adjustment of the height of the laser target 13. This structure is easy to operate and can quickly calibrate the target center to the pipe center position, effectively eliminating the influence of pipe diameter changes on the measurement benchmark, ensuring the accuracy of laser beam centering and elevation control, and greatly improving construction efficiency.
