Technical Field

[0001] This invention belongs to the technical field of tunnel construction, specifically relating to a platform device and method for measuring the angle of buried pipelines. Background Technology

[0002] Currently, cryogenic technology is widely used in shield tunnels and connecting passages. The application of cryogenic circulation pipe reinforcement in each shield tunnel entrance and connecting passage exceeds 2000 meters. Strict control of drilling angles is crucial, especially in urban subway construction where numerous pipelines and obstacles cause drilling rigs to repeatedly penetrate the soil, resulting in low accuracy of drilling elevation and depression angles. In the past, inspectors used wooden circular protractors and plumb lines, which had limitations in measuring pipe length. Furthermore, protractors and plumb lines were inconvenient to fix and easily affected by external factors, making them cumbersome, tedious, and inaccurate. Summary of the Invention

The operating platform is fixed by clamping the bushings with the platform brake knobs.

[0007] A sliding shoe is fitted onto the swing arm, and a sliding shoe locking screw is provided on the sliding shoe to fix the sliding shoe onto the swing arm. A bushing is fixed to the sliding shoe, and the operating platform is installed between the bushing on the sliding shoe via a platform rotation shaft.

[0008] A leveling adjustment and locking assembly is also installed between the sleeve and the operating platform. The leveling adjustment and locking assembly includes a plumb rod, a parallel connecting rod, and a locking component. A plumb rod is respectively mounted on the sleeve rotation shaft on both sides of the sleeve. The middle of the plumb rod is hinged to the parallel connecting rod, and a plumb block is provided at the lower end of the plumb rod.

[0009] The operating platform adopts an L-shaped plate, including a horizontal plate and a vertical plate, which are perpendicular to each other. The platform rotation axis is fixed at both ends at the junction of the horizontal and vertical plates. The lower ends of the vertical plate are provided with vertical plate rotation axes. The distance between the platform rotation axis and the vertical plate rotation axis is equal to the distance between the sleeve rotation axis and the hinge point of the vertical rod and the parallel connecting rod. The other end of the parallel connecting rod is hinged to the vertical plate rotation axis, and the length of the parallel connecting rod is equal to the distance between the sleeve rotation axis and the platform rotation axis.

[0010] A synchronizing shaft for the plumb rods is installed between the plumb rods on both sides of the sleeve. The synchronizing shaft can rotate freely. A limiting sleeve is set in the middle of the synchronizing shaft. A limiting sleeve locking screw is set on the limiting sleeve. A locking rod bearing is set in the middle of the lower side of the sleeve. A locking rod that can swing freely is installed through the locking rod bearing. The locking rod is fitted in the limiting sleeve.

[0011] Furthermore, the horizontal plate extends outward from the end facing the vertical plate, and a counterweight is provided on the extension to eliminate the eccentric force of the L-shaped plate. A handle 7 is also fixed between the outer ends of the swing rod 2, and the handle 7 simultaneously fixes the swing rod 2 on both sides. A synchronous connecting rod is provided between the vertical rods 4.

[0012] A method for measuring the angle of a buried pipe using a platform device for measuring the angle of a buried pipe includes the following steps:

[0013] S1. Prepare a PE pipe with one end sealed, and embed an LED flashlight inside the PE pipe;

[0020] S5. Adjust the center of the crosshairs of the theodolite to align with the center of the LED light bead inside the pipe. The angle read from the theodolite dial (based on the principle of parallel line angles) is the inclination angle of the borehole pipe being measured.

[0021] The beneficial effects of the present invention are as follows: Compared with the prior art, the beneficial technical effects of the above-mentioned platform device and method for measuring the inclination angle of a pipeline are: it can measure the angle of the borehole at any time, especially for long and deep pipelines in a concealed state, and exposed short pipelines, and can adjust and correct the borehole angle of the pipeline in a timely manner.

[0022] As the drilling depth changes, the buried pipeline angle measurement platform and method provided by this invention can measure and observe the drilling angle at any time, adjust it at any time, and quickly detect it, thereby improving the accuracy of drilling at the elevation and depression angles in one operation, ensuring the accuracy of the drilling angle, and avoiding the situation of repeated drilling, back-drilling, and large and inaccurate errors after drilling.

Implementation

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The contents not described in detail in the embodiments of the present invention are prior art known to those skilled in the art.

[0032] Example 1: The main technical problem solved by this invention is to provide a platform device and method for measuring the inclination angle of a pipeline. The drilling angle is measured and observed continuously as the drilling depth increases, allowing for timely adjustments and rapid detection. This improves the accuracy of drilling at both elevation and depression angles, ensures the accuracy of the drilling angle, and avoids the problems of repeated drilling, back-drilling, and large or inaccurate errors after drilling.

[0033] like Figure 1 As shown, this invention provides a platform device for measuring the angle of buried pipes. The platform is fixed to the pipe opening, providing a horizontal platform for placing a theodolite, which is then used to measure the angle of the buried pipe. Specifically, the platform device includes a sleeve 1, swing rods 2, and an operating platform 3. The sleeve 1 is fitted onto the pipe opening, a set of parallel swing rods 2 are hinged to both sides of the sleeve 1, and the operating platform 3 is installed between the swing rods 2 and located below the sleeve 1.

[0034] Sleeve 1 has a sleeve rotating shaft 12 fixed on both sides. The sleeve rotating shaft 12 is a threaded column with external thread. The end of the swing rod 2 is provided with a collar and fitted onto the threaded column. The inner diameter of the collar is larger than the diameter of the threaded column. The swing rod 2 can swing freely around the sleeve rotating shaft 12.

[0035] A swing arm brake knob 13 is fitted onto the sleeve rotation shaft 12 on the outer side of the swing arm 2. The swing arm brake knob 13 is a nut whose size matches that of the sleeve rotation shaft 12.

[0036] By tightening the lever brake knob 13, the nut and the side wall of the sleeve clamp the collar, and the position of the lever is fixed by friction.

[0037] A sleeve locking wire 11 is provided on the upper side of the sleeve 1. When the sleeve locking wire 11 is rotated, the locking wire presses against the outer wall of the pipe opening. The sleeve is fixed to the pipe opening of the buried pipe by the locking wire. The buried pipe is a steel pipe, so there is no need to worry about the locking wire damaging the pipe.

[0038] The operating platform 3 is a thin steel plate. Bolts are welded to both sides of the end of the steel plate to serve as the platform rotation shaft 31. The nuts of the bolts are welded to the edge of the steel plate, and the threaded section of the bolts faces outward. At the same time, bushings 23 corresponding to the bolts are set on the swing rods 2 on both sides. The inner diameter of the bushing 23 is larger than the diameter of the platform rotation shaft 31, and the platform rotation shaft 31 is inserted into the corresponding bushing 23.

[0039] A platform brake knob 24 is fitted on the platform rotating shaft 31 outside the bushing. The platform brake knob 24 is a nut that matches the size of the platform rotating shaft 31. By tightening the platform brake knob 24, the platform brake knob 24 and the nut of the bolt clamp the bushing from both sides, thereby fixing the operating platform 3.

[0040] The specific construction method is as follows: a steel sleeve 1 is fitted onto the pipe opening of the buried pipe, and the sleeve and pipe opening are fixed by tightening the sleeve locking screw 11. The swing rod 2 is rotated to a suitable angle, and the swing rod brake knob 13, which is fitted on the outermost side of the sleeve rotation shaft 12, is rotated to clamp and fix the end of the swing rod 2, thereby fixing the entire swing rod. The swing rods on both sides are fixed with the same tilt angle. The operating platform 3, which is hinged to the swing rod, is rotated, and a spirit level or other leveling tool is used to keep the operating platform 3 level. The platform brake knobs 24 on both sides are rotated to clamp and fix the platform, thereby providing a stable measuring platform for measuring the tilt angle of the buried pipe.

[0041] like Figure 6 As shown, the method for measuring the angle of a buried pipe using this platform device is as follows:

[0042] S1. Prepare a PE pipe with one end sealed, and embed an LED flashlight inside the PE pipe;

[0043] S2. Place the PE pipe with the built-in LED flashlight parallel to the pipe being measured;

[0044] S3. Install a platform device for measuring the angle of buried pipes at the pipe opening of the pipe being measured;

[0045] S3-1. The sleeve 1 is fitted onto the pipe opening and fixed to the pipe opening by the sleeve locking screw 11;

[0046] S3-2. Adjust and lock the tilt of the swing arm 2 to keep the sleeve 1 and the operating platform 3 at a certain height;

[0047] S3-3. Adjust and lock the operating platform 3 to keep it horizontal;

[0048] S4. Place the theodolite on operating platform 3;

[0049] S5. Adjust the center of the crosshairs of the theodolite to align with the center of the LED light bead inside the pipe. The angle read from the theodolite dial (based on the principle of parallel line angles) is the inclination angle of the borehole pipe being measured.

[0050] Example 2: Based on Example 1, as follows Figure 1As shown, a sliding shoe 21 is fitted onto the swing arm 2. The sliding shoe 21 is provided with a sliding shoe locking screw 22 for fixing the sliding shoe onto the swing arm 2. A bushing 23 is fixed to the sliding shoe 21. The operating platform 3 is installed between the bushings 23 on the sliding shoe through a platform rotation shaft 31.

[0051] Move the slide shoe 21 along the swing arm 2, and fix the slide shoe 21 in the appropriate position by turning the slide shoe locking screw 22. Slide the slide shoe back and forth to adjust the length of use and achieve the operating space of the (theodolite) instrument.

[0052] The rotating steel plate operating platform includes left and right platform brake knobs 24. The rotation is based on the aforementioned back-and-forth moving slippers. The rotating steel plate operating platform is adjusted to a near-horizontal angle that is easy to observe, so that it provides a stable operating platform for placing the (theodolite) instrument. The platform brake knob keeps the position stable.

[0053] Example 3: In the platform device provided in Example 1, after the sleeve is fixed, the operating platform 3 needs to be adjusted by a level or other leveling tools. In actual use, the steps are relatively cumbersome. Therefore, this example provides a synchronous locking structure through a level adjustment locking component to realize the synchronous adjustment and fixing of the sleeve and the operating platform 3, thereby simplifying the ease of use of the platform device, improving the speed of platform deployment, and achieving more efficient work.

[0054] As shown in 2-4, the levelness adjustment and locking assembly includes a plumb rod 4, a parallel connecting rod 5, and a locking assembly 6; wherein the plumb rod 4 is respectively mounted on the sleeve rotation shaft 12 on both sides of the sleeve 1, the parallel connecting rod 5 is hinged to the middle of the plumb rod 4, the lower end of the plumb rod 4 is provided with a plumb block 41, and the end of the plumb rod 4 is provided with a through hole with an inner diameter larger than that of the sleeve rotation shaft 12, so that the plumb rod can hang freely on the rotation shaft. Through the weight of the plumb rod 4 and the plumb block 41 at the end, it can be ensured that the plumb rod 4 is always vertically downward in the free state, and the swing rod brake knob 13 is installed on the outside of the plumb rod 4.

[0055] The operating platform 3 adopts an L-shaped plate, including a horizontal plate 32 and a vertical plate 33. The horizontal plate 32 and the vertical plate 33 are perpendicular to each other. The platform rotation shaft 31 is fixed at both ends of the junction of the horizontal plate 32 and the vertical plate 33. The lower ends of the vertical plate 33 are provided with vertical plate rotation shafts 34. The distance between the platform rotation shaft 31 and the vertical plate rotation shaft 34 is equal to the distance between the sleeve rotation shaft 12 and the hinge point of the vertical rod 4 and the parallel connecting rod 5. The other end of the parallel connecting rod 5 is hinged to the vertical plate rotation shaft 34. The length of the parallel connecting rod 5 is equal to the distance between the sleeve rotation shaft 12 and the platform rotation shaft 31.

[0056] The pendulum 2, the plumb line 4, the parallel connecting rod 5, and the vertical plate 33 form a parallelogram structure. With the plumb line 4 always remaining vertical due to gravity, the vertical plate 33 also remains vertical. At this time, the horizontal plate 32, which is perpendicular to the vertical plate 33, is naturally in a horizontal state and does not require any additional adjustment.

[0057] A vertical rod synchronous shaft 42 is installed between the vertical rods 4 on both sides of the sleeve. The vertical rod synchronous shaft 42 can rotate freely. A limit sleeve 421 is provided in the middle of the vertical rod synchronous shaft 42. A limit sleeve locking screw 422 is provided on the limit sleeve 421. A locking rod bearing 61 is provided in the lower middle part of the sleeve 1. A locking rod 62 that can swing freely is installed through the locking rod bearing 61. The locking rod 62 is fitted in the limit sleeve 421.

[0058] During the adjustment process, the locking screw 422 of the limiting sleeve is loosened, and the locking rod 62 rotates freely with the adjustment of the plumb rod 4 and moves freely in the limiting sleeve 421. After the plumb rod 4 is adjusted, the locking screw 422 of the limiting sleeve is turned so that the locking screw presses the locking rod 62 to fix it. A stable triangular structure is formed between the locking rod 62, the plumb rod 4 and the sleeve, locking the positional relationship between the plumb rod and the sleeve. Thus, the position of the fixed operating platform 3 is fixed by the structural characteristics of the parallelogram, realizing the rapid arrangement of the platform device.

[0059] In this embodiment, since the operating platform 3 adopts an L-shaped plate, the horizontal plate 32 and the vertical plate 33 form an eccentric structure. Under the influence of the gravity of the horizontal plate 32, the vertical plate 33 will deflect, thus affecting the direction of the plumb line through the parallelogram structure. To eliminate this effect, this embodiment further extends the horizontal plate 32 outward toward the end facing the vertical plate 33, and a counterweight 35 is provided on the extension. The counterweight 35 keeps the horizontal plate 32 on both sides of the vertical plate 33 balanced, minimizing the eccentric force generated by the horizontal plate.
