Description

Technical Field

[0001] The utility model relates to the technical field of inclinometer tube auxiliary installation, in particular to an inclinometer tube installation auxiliary device for horizontal pipe curtain deformation monitoring. Background Art

[0002] Currently, when other engineering activities (e.g., tunnel construction) are carried out above the surrounding rock around subway tunnels, a horizontal pipe curtain (i.e., a row of steel pipes) is usually installed horizontally above the surrounding rock to reduce surrounding rock deformation and subway tunnel structural damage caused by engineering disturbances.

[0003] In the prior art, an inclinometer tube is usually installed in the horizontal pipe curtain steel pipe. By monitoring the deflection of the inclinometer tube, the deflection of the horizontal pipe curtain is observed, and thus the damage of the subway tunnel structure is observed.

[0004] However, due to certain installation errors caused by manual installation, after the inclinometer casing is installed, its vertical center line does not coincide with the vertical center line of the steel pipe, that is, they are not aligned.

[0005] Therefore, there is an urgent need for an auxiliary device for installing an inclinometer tube for horizontal pipe curtain deformation monitoring, so that the inclinometer tube can be accurately installed. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides an auxiliary device for installing an inclinometer tube for horizontal pipe curtain deformation monitoring, which realizes accurate installation of the inclinometer tube by setting a first positioning component, a second positioning component and a total station.

[0007] The utility model provides an auxiliary device for installing an inclinometer tube for monitoring deformation of a horizontal pipe curtain, which is characterized by: an auxiliary installation mechanism arranged inside the steel pipe for fixing the inclinometer tube, a positioning mechanism arranged outside the steel pipe for positioning the center line of the auxiliary installation mechanism, and a displacement mechanism arranged below the positioning mechanism for moving along the lifting direction and the radial direction of the steel pipe;

[0008] The auxiliary installation mechanism includes an inner support ring, the inner surface of which is provided with three first positioning assemblies spaced 120 degrees apart, a fixing clamp fixedly provided at the bottom of the inner support ring, and the inclinometer tube disposed within the fixing clamp, and a pair of second positioning assemblies respectively provided horizontally and vertically on the inner surface of the inclinometer tube;

[0009] The positioning mechanism includes a total station;

[0010] The shifting mechanism includes a shifting slide.

[0011] The above-mentioned inclinometer tube installation auxiliary device for horizontal pipe curtain deformation monitoring is characterized in that the first positioning component includes a positioning prism that cooperates with the total station.

[0012] The above-mentioned inclinometer tube installation auxiliary device for horizontal pipe curtain deformation monitoring is characterized in that the second positioning component includes a reflective sheet that cooperates with the total station.

[0013] The above-mentioned inclinometer tube installation auxiliary device for horizontal pipe curtain deformation monitoring is characterized in that it also includes at least two pairs of first limit assemblies passed through the steel pipe and the inner support ring for limiting the relative position between the steel pipe and the inner support ring and fixedly connected, and the first limit assembly includes a first bolt and a first nut.

[0014] The above-mentioned inclinometer tube installation auxiliary device for horizontal pipe curtain deformation monitoring is characterized in that the fixing clamp includes a pair of clamp ears, and a first opening is formed on the surface of the clamp ears.

[0015] The above-mentioned inclinometer tube installation auxiliary device for horizontal pipe curtain deformation monitoring is characterized in that it also includes a second limiting component penetrated through the first opening and the second opening for limiting the relative position between the fixing clamp and the inclinometer tube, and the second limiting component includes a second bolt and a second nut.

[0016] The above-mentioned inclinometer tube installation auxiliary device for horizontal pipe curtain deformation monitoring is characterized by further comprising an annular pad disposed between the fixing clamp and the inclinometer tube for uniformly applying stress to the inclinometer tube.

[0017] The beneficial effect reasoning analysis is as follows:

[0018] In the prior art, due to certain installation errors caused by manual installation, after the inclinometer casing is installed, its vertical centerline does not coincide with the vertical centerline of the steel pipe, that is, they are not aligned.

[0019] In the technical solution of the present invention, a first positioning component is provided on the inner surface of the inner support ring and a second positioning component is provided on the inner surface of the fixed clamp. The total station is used to compare and analyze the difference between the theoretical and actual position data of the two positioning components (i.e., the first positioning component and the second positioning component). When the data are inconsistent, the inner support ring or the inclinometer tube is rotated until the theoretical installation position and the actual installation position are consistent, so that the vertical center line of the inclinometer tube and the vertical center line of the steel pipe coincide, thereby achieving accurate installation of the inclinometer tube.

[0020] This avoids the situation in the prior art where, due to certain installation errors caused by manual installation, the vertical center line of the inclinometer tube does not coincide with the vertical center line of the steel pipe after installation, that is, they are not aligned.

[0021] Therefore, by adopting the technical solution of the present invention, accurate installation of the inclinometer casing can be achieved, that is, the deviation of the inclinometer casing during installation can be avoided. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are intended only to illustrate the relevant utility model and are not intended to limit the scope of the utility model. It should also be noted that, for ease of description, only the portions relevant to the utility model are shown in the accompanying drawings.

[0032] It should be noted that, in the absence of conflict, the embodiments of the present invention, that is, the features of the embodiments, can be combined with each other. The present invention will be described in detail below with reference to the embodiments and in conjunction with the accompanying drawings.

[0033] In the prior art, due to certain installation errors caused by manual installation, after the inclinometer casing is installed, its vertical centerline does not coincide with the vertical centerline of the steel pipe, that is, they are not aligned.

[0034] Based on this, the utility model provides an auxiliary device for installing an inclinometer tube for horizontal pipe curtain deformation monitoring, which realizes accurate installation of the inclinometer tube by setting a first positioning component, a second positioning component and a total station.

[0035] Figure 1This is a longitudinal sectional view of an auxiliary device for installing an inclinometer tube for horizontal pipe curtain deformation monitoring provided by the utility model. Figure 2 for Figure 1 Left view of Figure 3 for Figure 1 Top view without the total station placed.

[0036] See also Figure 1 The utility model provides an auxiliary device for installing an inclinometer tube for horizontal pipe curtain deformation monitoring, comprising: an auxiliary installation mechanism disposed within a steel pipe 2 for fixing the inclinometer tube 1; a positioning mechanism disposed outside the steel pipe 2 for positioning the center line of the auxiliary installation mechanism; and a shifting mechanism disposed below the positioning mechanism for moving in the lifting direction and in the radial direction of the steel pipe 2.

[0037] The auxiliary installation mechanism includes an inner support ring 3, with three first positioning assemblies arranged at equal intervals of 120° on its circumferential inner surface. A fixing clamp 4 is fixed to the bottom of the inner support ring 3, and an inclinometer tube 1 is disposed within the fixing clamp 4. A pair of second positioning assemblies are respectively provided horizontally and vertically on the circumferential inner surface of the inclinometer tube 1.

[0038] The positioning mechanism includes a total station 5;

[0039] The shifting mechanism includes a shifting slide 6 .

[0040] The connection between the first positioning assembly and the inner support ring 3 can be a detachable connection, for example, a snap connection. After the inclinometer casing 1 is installed, the first connection assembly can be removed from the inner support ring 3.

[0041] It should be noted that multiple inclinometer tubes 1 need to be set in the axial direction of the steel pipe 2. Therefore, after the first inclinometer tube 1 is installed at the pipe mouth of the steel pipe 2, the first positioning assembly and the second positioning assembly can be removed to assist in the installation of subsequent multiple inclinometer tubes 1 in sequence until all inclinometer tubes 1 are installed.

[0042] The inner support ring 3 can transfer the load on the steel pipe 2 to the fixing clamp 4, and then transfer it to the inclinometer casing 1 through the fixing clamp 4. It is understandable that the inner support ring 3 can also be replaced by other components with load transfer function.

[0043] The shift slide 6 can specifically be an XYZ three-axis fine-tuning platform.

[0044] Similarly, the connection between the second positioning assembly and the inclinometer casing 1 can also be a detachable connection, for example, by gluing. After the inclinometer casing 1 is installed, the second connection assembly can be torn off from the inclinometer casing 1.

[0045] The specific alignment process of the inclinometer casing 1 is divided into the following two aspects:

[0046] On the one hand, it is necessary to achieve that the vertical center line of the inner support ring 3 coincides with the vertical center line of the steel pipe 2, that is, alignment. First, move the shift slide 6, and use the total station 5 set on the shift slide 6 to measure the theoretical installation positions of the three first positioning components (for example, three first coordinate data). Second, connect the first positioning component, the inner support ring 3, and the fixed clamp 4. Third, place the integrated component connected in the second step in the steel pipe 2. Fourth, use the total station 5 again to measure the actual installation position of the first positioning component (for example, three second coordinate data). Fifth, compare whether the coordinate data of the two measurements are consistent. If not, rotate the position of the inner support ring 3 in the steel pipe 2 in real time, and compare it with the first coordinate data again until they are completely consistent. Then the vertical center line of the inner support ring 3 coincides with the vertical center line of the steel pipe 2, that is, alignment.

[0047] On the other hand, it is necessary to achieve the coincidence of the vertical center line of the inclinometer tube 1 and the vertical center line of the steel pipe 2, that is, alignment. First, move the shift slide 6, and use the total station 5 set on the shift slide 6 to measure the theoretical installation positions of the three second positioning components (for example, three third coordinate data). Second, connect the second positioning component and the inclinometer tube 1. Third, place the integrated component connected in the second step in the fixed clamp 4. Fourth, use the total station 5 again to measure the actual installation position of the second positioning component (for example, three fourth coordinate data). Fifth, compare whether the coordinate data of the two measurements are consistent. If not, rotate the position of the inclinometer tube 1 in the fixed clamp 4 in real time, and compare it with the third coordinate data again until they are completely consistent. Then the vertical center line of the inclinometer tube 1 and the vertical center line of the fixed clamp 4 coincide.

[0048] Since the fixing clamp 4 and the inner support ring 3 are fixedly connected, and the vertical center line of the inner support ring 3 coincides with the vertical center line of the steel pipe 2, it can be considered that the vertical center line of the fixing clamp 4 coincides with the vertical center line of the steel pipe 2. Therefore, when the vertical center line of the inclinometer tubing 1 coincides with the vertical center line of the fixing clamp 4, the vertical center line of the inclinometer tubing 1 coincides with the vertical center line of the steel pipe 2, that is, they are aligned.

[0049] Based on the above two aspects, the installation of the inclinometer casing 1 is completed.

[0050] The beneficial effect reasoning analysis is as follows:

[0051] In the prior art, due to certain installation errors caused by manual installation, after the inclinometer casing is installed, its vertical centerline does not coincide with the vertical centerline of the steel pipe, that is, they are not aligned.

[0052] In the technical solution of the present invention, a first positioning component is provided on the inner surface of the inner support ring 3, and a second positioning component is provided on the inner surface of the fixed clamp. The total station is used to compare and analyze the difference between the theoretical and actual position data of the two positioning components (i.e., the first positioning component and the second positioning component). When the data are inconsistent, the inner support ring 3 or the inclinometer tube 1 is rotated until the theoretical installation position and the actual installation position are consistent, so that the vertical center line of the inclinometer tube 1 and the vertical center line of the steel pipe 2 coincide, thereby achieving accurate installation of the inclinometer tube 1.

[0053] This avoids the situation in the prior art where, due to certain installation errors caused by manual installation, the vertical center line of the inclinometer tube does not coincide with the vertical center line of the steel pipe after installation, that is, they are not aligned.

[0054] Therefore, by adopting the technical solution of the present invention, the accurate installation of the inclinometer casing 1 can be achieved, that is, the deviation of the inclinometer casing 1 during installation can be avoided.

[0055] In the above-mentioned embodiment, an auxiliary device for installing an inclinometer tube for monitoring deformation of a horizontal pipe curtain is introduced. In another embodiment of the present invention, a specific type of the first positioning assembly is introduced.

[0056] For example, the first positioning component includes a positioning prism 7 that cooperates with the total station 5 .

[0057] In the above-mentioned embodiment, a specific type of the first positioning assembly is introduced. In another embodiment of the present invention, a specific type of the second positioning assembly is introduced.

[0058] For example, the second positioning component includes a reflective sheet 8 that cooperates with the total station 5 .

[0059] In the embodiment described above, a specific type of the second positioning assembly is introduced. In another embodiment of the present invention, a position limiting assembly is introduced for limiting the relative position between the inner support ring 3 and the steel pipe 2 after the inner support ring 3 and the steel pipe 2 are aligned.

[0060] For example, it also includes at least two pairs of first limiting components that are passed through the steel pipe 2 and the inner support ring 3 and are fixedly connected to limit the relative position between the steel pipe 2 and the inner support ring 3. The first limiting components include a first bolt 9 and a first nut 10.

[0061] In the embodiment described above, a position limiting assembly is introduced for limiting the relative position between the inner support ring 3 and the steel pipe 2 after the inner support ring 3 and the steel pipe 2 are aligned. In another embodiment of the present invention, a fixing clamp 4 is introduced.

[0062] For example, the fixing clamp 4 includes a pair of clamp ears 4 - 1 , and a first opening is formed on the surface of the clamp ears 4 - 1 .

[0063] The above-mentioned embodiment introduces the specific structure of the fixing clamp 4. In another embodiment of the present invention, a limiting assembly is introduced to limit the relative position between the inclinometer tubing 1 and the fixing clamp 4 after the inclinometer tubing 1 and the steel pipe 2 are aligned.

[0064] For example, a second limiting assembly is further included which is passed through the first opening and is used to limit the relative position between the fixing clamp 4 and the inclinometer casing 1 . The second limiting assembly includes a second bolt 11 and a second nut 12 .

[0065] The above-described embodiment introduces a limit assembly for limiting the relative position between the inclinometer tubing 1 and the fixing clamp 4 after the inclinometer tubing 1 and the steel pipe 2 are aligned. In another embodiment of the present invention, an assembly is introduced for ensuring uniform force on the inclinometer tubing 1.

[0066] For example, an annular gasket 13 is further included, which is provided between the fixing clamp 4 and the inclinometer casing 1 and is used to ensure that the inclinometer casing 1 is subjected to uniform stress.

[0067] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any simple modification, change and equivalent structural change made to the above embodiment based on the technical essence of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
