Description

Technical Field

[0001] The utility model belongs to the technical field of pipe pile inclination measurement, and in particular relates to a pipe pile inclination measurement device. Background Art

[0002] In civil engineering, the inclination of a pipe pile is an important indicator for evaluating its stability and safety. At present, a general pipe pile inclination measuring device, such as a static pressure pipe pile inclination measuring device disclosed in CN208486267U, comprises a chain rod fixing part, a sleeve, four strain measuring elements, a chain rod connecting part, a chain rod and a plumb bob. The chain rod fixing part is fixed to the upper end of the sleeve perpendicular to the sleeve wall. The upper end of the chain rod is hinged to the center of the chain rod fixing part through the chain rod connecting part, and the lower end is fixedly connected to the plumb bob. The four strain measuring elements are all vertically fixed on the chain rod and have no contact with the sleeve. The strain measuring element is connected to a signal line of an inclination display device. When the pipe pile is tilted, the chain rod fixing part is fixed to the upper end of the sleeve perpendicular to the sleeve wall. The upper end of the chain rod is hinged to the center of the chain rod fixing part through the chain rod connecting part, and the lower end is fixedly connected to the plumb bob. The four strain measuring elements are vertically fixed on the chain rod and have no contact with the sleeve. The strain measuring element is connected to a signal line of an inclination display device. Under the influence of the plumb line, the steel bar with the strain measuring element interacts with the sleeve, and there will be strain output, thereby monitoring the inclination of the pipe pile. It has the characteristics of high measurement accuracy, convenient operation, and real-time monitoring of verticality. However, in the above structure, the response action of the entire measuring device to the inclination is mainly performed by the natural drooping action of the plumb bob. However, the premise for the plumb bob to work is that one end of it is connected to the hanging point and can ensure free movement. At this time, in addition to gravity, there are other factors, such as air flow and shaking of the surrounding environment that cause the movement of the plumb bob. At this time, there is a probability that the plumb bob will shake under the action of the airflow, resulting in inaccurate measurement. For this reason, an accurate pipe pile inclination measurement device is needed. Utility Model Content

[0003] In order to solve the problem in the prior art that the plumb bob is easy to shake and thus causes inaccurate measurement results, the utility model provides a pipe pile inclination measuring device, which has the characteristic of high measurement accuracy.

[0004] The purpose of the utility model can be achieved through the following technical solutions:

[0005] A device for measuring the inclination of a pipe pile comprises an annular hoop, and two strip levels are arranged on the side of the hoop, the two strip levels are perpendicular to the axis of the hoop, and the two strip levels are symmetrically arranged about the axis of the hoop. The annular hoop is used to be sleeved on the outside of the pipe pile, and the hoop drives the two strip levels to rotate around the axis of the pipe pile.

[0006] As an optimal technical solution of the utility model, two installers are arranged on the side of the hoop, and the two installers are symmetrically arranged around the axis of the hoop. The two installers are arranged corresponding to two strip levels, and the two strip levels are detachably connected to the hoop through the installers.

[0007] As a preferred technical solution of the utility model, a reference ring is printed on the side of the hoop, and the reference ring is perpendicular to the axis of the hoop. The reference ring is used to determine whether the two-line level gauges are perpendicular to the axis of the hoop.

[0022] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0023] See also Figure 1-5 A pipe pile inclination measuring device comprises an annular hoop 1, a side of the hoop 1 is provided with two strip-shaped level gauges 2, the strip-shaped level gauges 2 are perpendicular to the axis of the hoop 1, the strip-shaped level gauges 2 are symmetrically arranged around the axis of the hoop 1, the strip-shaped level gauges 2 are aligned with each other, the annular hoop 1 is used to be sleeved on the outside of the pipe pile 4, specifically, the hoop 1 is a thin ring, the inner diameter of the annular hoop 1 is consistent with the outer diameter of the strategic pipe pile 4, and at the same time, the side of the hoop 1 is provided with two strip-shaped level gauges 2, the two strip-shaped level gauges 2 are perpendicular to the axis of the hoop 1, and the two strip-shaped level gauges 2 are symmetrically arranged around the axis of the hoop 1;

[0024] The bar level 2 is simplified as a cylinder. At this time, the two cylindrical bar level 2 are set on both sides of the annular hoop 1, the axis of the cylindrical bar level 2 is perpendicular to the axis of the annular hoop 1, and the two cylinders are symmetrical around the axis of the annular hoop 1. At this time, when the annular hoop 1 is placed parallel to the ground, the two bar level 2 are also placed parallel to the ground. When the annular hoop 1 is not parallel to the ground, among the several tangents of the hoop 1, the tangents at the highest point and the lowest point of the inclined hoop 1 are parallel to the ground, and the other tangents intersect with the ground. The direction of the bar level 2 set on the side is consistent with the tangent of the hoop 1 at the position of the bar level 2. Therefore, as the hoop 1 rotates around its own axis, the bar level 2 is parallel to the ground when it rotates to the highest point and the lowest point on the side of the hoop 1. For example Figure 5 As shown in , in other positions it tilts itself, e.g. Figure 4 As shown in , since the two bar-shaped level gauges 2 are symmetrically arranged around the axis of the hoop 1, when the inclined hoop 1 rotates to a certain position, the two bar-shaped level gauges 2 are parallel to the ground at the same time. At this time, the angle between the line connecting the geometric centers of the two bar-shaped level gauges 2 and the ground is equal to the complementary angle of the inclination angle of the pipe pile 4;

[0025] When the strip level 2 is tilted relative to the ground, the bubble in the strip level 2 moves toward the upper end of the strip level 2. When the strip level 2 is parallel to the ground, the bubble in the strip level 2 is at the initial position. The operator can determine whether the strip level 2 is parallel to the ground by observing the bubble position.

[0026] When in use, the hoop 1 is sleeved on the outside of the pipe pile 4 to be measured, and the operator rotates the hoop 1 around the pipe pile 4, and the hoop 1 drives the two strip level gauges 2 to rotate around the axis of the pipe pile 4. During this process, the operator constantly observes the position of the bubbles in the two strip level gauges 2 and determines whether the bubbles are in the initial position. When the judgment result is yes, the operator measures the angle between the line connecting the geometric centers of the two strip level gauges 2 and the ground to obtain the inclination angle of the pipe pile 4, and completes the inclination measurement of the pipe pile 4;

[0027] By setting the measuring device as a hoop 1 and two bar-shaped levels 22, and when the hoop 1 is set on the inclined pipe pile 4, the angle between the axis line of the measuring device and the ground is judged according to the angle between the line connecting the two bar-shaped levels 22 adjusted to be horizontal and the ground, and then the inclination angle of the pipe pile 4 is judged to complete the inclination measurement. At the same time, compared with the solution involving electronic components, the structure of the entire device is relatively simple.

[0028] During the long-term use of the above structure, the strip level 22 is likely to be bumped and no longer perpendicular to the axis of the hoop 1. At this time, the operator needs to remove the strip level 22, inspect the strip level 22, and re-set the repaired or brand-new strip level 22 on the side of the hoop 1. To facilitate the disassembly and assembly of the strip level 22, two installers 2 are provided on the side of the hoop 1. The two installers 2 are correspondingly arranged with the two strip levels 2. The two strip levels 2 are detachably connected to the hoop 1 through the installers 2. At this time, the two installers 2 are also symmetrically arranged around the axis of the hoop 1, and ensure that the strip level 2 is still symmetrical with the axis of the hoop 1 after being arranged on the hoop 1.

[0029] In this embodiment, specifically, the installer 2 includes a base 121 and a placement table 122 extending from the base 121, the base 121 is a quadrangular prism structure, the long side of the quadrangular prism base 121 is perpendicular to the axial direction of the hoop 1, the long side of the quadrangular prism base 121 is smaller than the axial dimension of the strip level 22, the placement table 122 is parallel to the long side of the quadrangular prism base 121, the strip level 22 is horizontally arranged on the base 121 by pasting or clamping, at this time the strip level 22 is parallel to the placement table 122, and then parallel to the long side of the base 121, and perpendicular to the axial direction of the hoop 1, when disassembly is required, the operator removes the strip level 22 from the placement table 122.

[0030] After the strip level 22 is installed on the hoop 1, there is a probability that the installation position of the strip level 22 is offset and not perpendicular to the axis. At this time, the strip level 22 is likely to be unable to return the bubble to the initial position when it is at the highest point or the lowest point of the inclined hoop 1, so that the operator can identify it. In order to facilitate the operator to check whether the strip level 22 is installed in place, a reference ring 11 is printed on the side of the hoop 1. The reference ring 11 is perpendicular to the axis of the hoop 1. The reference ring 11 is used to determine whether the two strip levels 2 are perpendicular to the axis of the hoop 1;

[0031] Specifically, a plurality of annular patterns are formed on the side of the hoop 1 by printing, and each annular pattern is perpendicular to the axis of the hoop 1. At the same time, since the long side dimension of the quadrangular prism base 121 is smaller than the axial dimension of the strip level 22, after the strip level 22 is set on the installer 2, both ends protrude from the installer 2 along its own axis. When observed from a direction perpendicular to the axis of the strip level 22, both ends of the strip level 22 partially overlap with the reference ring 11.

[0032] Specifically, the annular pattern of the reference ring 11 is a plurality of color rings, which are arranged axially along the hoop 1, and are parallel to each other. The colors of adjacent color rings are different. For example, a color ring is a red annular pattern, and the shapes of the two adjacent color rings of the red color ring pattern are consistent with the red color ring, and the color is blue. The color ring adjacent to the blue color ring is green, and so on.

[0033] When the installation position of the bar level 22 is correct, when observing from a direction perpendicular to the axis of the bar level 22, the parts of the two ends of the bar level 22 protruding from the installer 2 overlap with the same annular pattern. At this time, the operator can judge that the bar level 22 is correctly installed based on this. When the installation position of the bar level 22 is incorrect and it is tilted, the parts of the two ends of the bar level 22 protruding from the installer 2 no longer overlap with the same annular pattern. For example, one end overlaps with a certain annular pattern and the other end overlaps with another annular pattern. At this time, the operator can judge that the bar level 22 is not perpendicular to the axis of the hoop 1 based on the overlap of the two ends with different annular patterns, and thus adjust it;

[0034] By providing the reference ring 11 , it is convenient for the operator to quickly determine whether the strip level 22 is set at a position perpendicular to the axis of the hoop 1 .

[0035] In the above structure, the operator needs to manually measure the geometric center line of the two strip level gauges 22 as a reference line, and measure the angle between the reference line and the ground, and then determine the inclination angle of the pipe pile 4, which is less convenient to use. In order to automatically form the reference line, a laser emitter is provided on the side of the hoop 1, and the laser emission direction of the laser emitter is perpendicular to the axis line of the hoop 1, and the laser emission direction of the laser emitter is perpendicular to the axis line of any strip level gauge 2;

[0036] Specifically, a clamp is provided on the side of the hoop 1, and the clamp fixes the laser emitter on the side of the hoop 1. After fixation, the laser emitted by the laser emitter is perpendicular to the axis line of the hoop 1 and the axis line of the bar level 22. According to geometric deduction, the laser emitted by the laser emitter is parallel to the line connecting the geometric centers of the two bar levels 22. At this time, the angle between the laser and the ground is equal to the angle between the line connecting the geometric centers of the two bar levels 22 and the ground. When the operator adjusts the hoop 1 until the two bar levels 22 are parallel to the ground, the angle between the laser and the ground is measured, and the inclination angle of the pipe pile 4 can be quickly obtained, thereby improving the convenience of use.

[0037] To ensure that the operator can directly see whether the laser 3 is in working condition and avoid eye injury by laser, the laser transmitter is provided with a working status indicator light. The indicator light emits red light when the laser 3 is working, reminding the operator to avoid looking directly at the laser 3 light source.

[0038] The working principle and use process of this utility model:

[0039] When in use, the hoop 1 is sleeved on the outside of the pipe pile 4 to be measured, and the operator rotates the hoop 1 around the pipe pile 4, and the hoop 1 drives the two strip levels 2 to rotate around the axis of the pipe pile 4. During this process, the operator constantly observes the position of the bubbles in the two strip levels 2 and determines whether the bubbles are in the initial position. When the judgment result is yes, the operator measures the angle between the line connecting the geometric centers of the two strip levels 2 and the ground to obtain the inclination angle of the pipe pile 4 and complete the measurement of the inclination of the pipe pile 4.
