Description

Technical Field

[0001] The utility model belongs to the technical field of prestressed pipe construction, and in particular relates to a measuring and positioning device for prestressed pipes anchored in a suspension bridge. Background Art

[0002] During suspension bridge construction, positioning prestressed pipe anchors is one of the most critical processes. Workers working at height must quickly and accurately locate the prestressed pipes. Because the prestressed pipe anchors used in suspension bridges are steel pipes with arbitrary slopes, measuring and locating the pipes requires determining the centerline coordinates to correct for positional deviations.

[0003] At present, there are two traditional measurement methods. One is to use a three-dimensional map to lay out the pipe wall coordinates. The disadvantage is that the workload is large and the measurement point error is large. The other is to process a circular plate according to the pipe diameter, and stick a reflective sheet or install a prism in the plate. The disadvantage is that the reflective sheet has a large error and cannot meet the design accuracy. The installation of the prism is difficult. In addition, there are usually many obstacles at the position of the prestressed pipe to be measured, and the measuring instrument can only be set up facing the front of the prestressed pipe. Therefore, the measuring instrument and the measurement position are not connected, and the instrument position needs to be changed as needed, which is very limited in use.

[0004] Therefore, there is an urgent need for a measurement and positioning device that can quickly locate the position of a pipeline and is easy to use in locations with many obstacles. Utility Model Content

[0005] Based on the above technical problems, the utility model provides a measurement and positioning device for prestressed pipelines anchored in suspension bridges. The device is used in combination with a first disc and a second disc, and the first disc is rotated until the bubble level tube is centered, and then the connecting rod of the prism is erected at the vertex of the installation groove, thereby facilitating the rapid determination of the position of the prestressed pipeline.

[0006] The specific technical solution is:

[0007] The cam is secured to the top of the mounting plate and has an angular channel formed between a first end of an angular channel and a second end of an arc channel, the cam being secured to the top of the mounting plate and a second end of an arc channel.

[0008] In addition, the suspension bridge anchorage prestressed pipeline measurement and positioning device provided by the present invention in the above technical solution may also have the following additional technical features:

[0009] In the above technical solution, the limiting assembly includes: a first protrusion and a second protrusion; the first protrusion is arranged on one side of the inner wall of the slide groove; the second protrusion is arranged on the other side of the inner wall of the slide groove, and the first protrusion and the second protrusion are positioned; wherein the first protrusion and the second protrusion are both elastic bodies.

[0010] The above technical solution further comprises: a rubber ring; the outer wall of the rubber ring is in contact with the inner wall of the limiting groove, and the inner wall of the rubber ring is in contact with the outer wall of the second disc.

[0011] In the above technical solution, it also includes: a shielding piece; the shielding piece is a transparent acrylic plate, and the shielding piece cover is arranged at the installation groove.

[0012] In the above technical solution, the first disc and the second disc are both transparent acrylic plates.

[0013] The above technical solution further includes: four triangular indicator blocks; the four triangular indicator blocks are evenly arranged on the top surface of the second disc.

[0014] In the above technical solution, the bubble level tube is parallel to the horizontal axis of the center of the second disc, and the bubble level tube is perpendicular to the vertex of the positioning groove.

[0015] Compared with the prior art, the present invention provides a suspension bridge anchorage prestressed pipeline measurement and positioning device with the following beneficial effects:

[0016] 1. Insert the second disc into the prestressed tube, make the first disc close to the tube mouth of the prestressed tube, and rotate the first disc until the bubble level tube is centered. Then, erect the connecting rod of the prism at the vertex of the installation groove. At this time, the center coordinates of the circle can be obtained by measuring the prism, which makes it easier for workers to measure the center coordinates of the prestressed tube and then determine the position of the pipeline.

DETAILED DESCRIPTION

[0029] The following is a combination of specific implementation cases and attached Figure 1-9 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0030] A suspension bridge anchorage prestressed pipeline measurement and positioning device, such as Figure 1-9 As shown, it includes: a first disc 10, a second disc 12, a positioning groove 13, a mounting groove 14, a shock-absorbing pad 15, two slide grooves 16, a mounting block 17, two sliders 18, a bubble level tube 19 and two limit assemblies; the first disc 10 is provided with a limit groove 11; one end of the second disc 12 passes through the limit groove 11, and the top of the second disc 12 is embedded in the limit groove 11; the positioning groove 13 is in a water drop shape, and the positioning groove 13 is arranged on the top surface of the second disc 12, and the vertex of the positioning groove 13 is opposite to the center of the second disc 12, and the connecting rod 2 of the prism 25 6 stands upright in the positioning groove 13 and is opposite to the vertex position of the positioning groove 13; the mounting groove 14 is set on the top surface of the first disc 10; the shock-absorbing pad 15 is fixed to the bottom wall of the mounting groove 14; the two slide grooves 16 are respectively set on both sides of the inner wall of the mounting groove 14; the mounting block 17 is provided with a through groove, and the bottom of the mounting block 17 is in contact with the top surface of the shock-absorbing pad 15; the two sliders 18 are respectively connected to the two sides of the mounting block 17, and the two sliders 18 are respectively embedded in the two slide grooves 16; the bubble level tube 19 is embedded in the through groove; and the two limit assemblies are respectively set in the two slide grooves 16.

[0031] With the above structure, the second disc 12 is embedded in the prestressed tube 27, and the first disc 10 is placed close to the tube mouth of the prestressed tube 27. The first disc 10 is rotated until the bubble level tube 19 is centered. The connecting rod 26 of the prism 25 is then erected at the vertex of the mounting groove 14. At this time, the center coordinates can be obtained by measuring the position of the prism 25, thereby facilitating the staff to locate the center coordinates of the prestressed tube 27 and further determine the position of the pipeline.

[0032] Specifically, by embedding the bubble level tube 19 into the through groove of the mounting block 17, and using the sliders 18 on both sides of the mounting block 17 to slide into the slide groove 16 and press hard, the slider 18 moves to the bottom of the slide groove 16 through the two limiting components. The staff releases the pressing force, and the two limiting components limit the position of the slider 18, thereby limiting the mounting block 17, and the shock-absorbing pad 15 absorbs vibrations for the mounting block 17 to ensure the stability of the bubble level tube 19 when the device is hit.

[0033] In an embodiment of the present invention, the limiting assembly includes: a first protrusion 20 and a second protrusion 21; the first protrusion 20 is arranged on one side of the inner wall of the slide groove 16; the second protrusion 21 is arranged on the other side of the inner wall of the slide groove 16, and the first protrusion 20 and the second protrusion 21 are positioned; wherein the first protrusion 20 and the second protrusion 21 are both elastomers.

[0034] By arranging the first protrusion 20 and the second protrusion 21 in the slide groove 16, when the mounting block 17 is placed, the sliders 18 at both ends of the mounting block 17 are moved along the two slide grooves 16 respectively, and the mounting block 17 and the slider 18 are pressed hard. By utilizing the elastic properties of the first protrusion 20 and the second protrusion 21, the slider 18 passes through the first protrusion 20 and the second protrusion 21 until the slider 18 is moved to the bottom of the slide groove 16, and the first protrusion 20 and the second protrusion 21 are fit with the top surface of the slider 18, thereby achieving the purpose of limiting the position of the slider 18 and the mounting block 17.

[0035] Specifically, the first bump 20 and the second bump 21 of the present application are spring sheets.

[0036] In the embodiment of the present invention, the rubber ring 22 is further included. The outer wall of the rubber ring 22 is in contact with the inner wall of the limiting groove 11 , and the inner wall of the rubber ring 22 is in contact with the outer wall of the second disc 12 .

[0037] The rubber ring 22 increases the friction between the second disc 12 and the first disc 10 , thereby improving the stability of the first disc 10 and the second disc 12 during installation.

[0038] In the embodiment of the present invention, the device further comprises: a shielding sheet 23 ; the shielding sheet 23 is a transparent acrylic plate, and the shielding sheet 23 is covered on the installation groove 14 .

[0039] By setting the shielding piece 23 as a transparent acrylic plate, it can not only shield the installation groove 14 but also make it easier for staff to observe the bubble level tube 19.

[0040] Specifically, the mounting groove 14 is a T-shaped groove, so as to facilitate the placement of the shielding piece 23 .

[0041] In the embodiment of the present invention, the first disc 10 and the second disc 12 are both transparent acrylic plates.

[0042] By configuring the first disc 10 and the second disc 12 as transparent acrylic plates, it is possible to facilitate observation by workers when they install the first disc 10 and the second disc 12 at one end of the pipe.

[0043] Specifically, acrylic sheets have the characteristics of high wear resistance and hardness, so they have a long service life and can be recycled.

[0044] In the embodiment of the present invention, the second disk 12 further includes four triangular indicator blocks 24 ; the four triangular indicator blocks 24 are evenly arranged on the top surface of the second disk 12 .

[0045] By providing four triangular indicator blocks 24 , and all of the four triangular indicator blocks 24 point to the center of the circle, the prism 25 is guided to find the target.

[0046] In the embodiment of the present invention, the bubble level 19 is parallel to the horizontal axis of the center of the second disk 12 , and the bubble level 19 is perpendicular to the vertex of the positioning groove 13 .

[0047] By aligning the bubble level 19 with the horizontal axis of the center of the second disc 12 and the bubble level 19 with the apex of the positioning groove 13, the position of the bubble level 19 is used as a reference so that the first disc 10 can be accurately adjusted to a horizontal position when rotating.

[0048] Implementation process: By inserting the second disc 12 into the prestressed tube 27, and making the first disc 10 close to the tube mouth of the prestressed tube 27, and rotating the first disc 10 until the bubble level tube 19 is centered, the connecting rod 26 of the prism 25 is erected at the vertex of the mounting groove 14. At this time, the center coordinates can be obtained by measuring the position of the prism 25, thereby facilitating the staff to measure the center coordinates of the prestressed tube 27. Specifically, by inserting the bubble level tube 19 into the through groove of the mounting block 17, and using the sliders 18 on both sides of the mounting block 17 to slide into the slide groove 16 and press hard, the sliders 18 move to the bottom of the slide groove 16 through the two limit assemblies. The staff releases the pressing force, and the two limit assemblies limit the position of the slider 18, thereby limiting the mounting block 17. The shock-absorbing pad 15 absorbs vibrations of the mounting block 17 to ensure the stability of the bubble level tube 19 when the device is hit.
