Description

Technical Field

[0001] This application relates to the field of displacement monitoring technology, and in particular to a target for displacement monitoring. Background Technology

[0002] Static load testing of foundations is a common and traditional testing method in foundation inspection. This test typically uses laser displacement sensors and targets to monitor the displacement of the bearing plane during settlement. By securing the target to the corresponding bearing plane, the laser displacement sensor observes the target's displacement changes during the static load test, thus monitoring the settlement of the bearing plane. Existing targets used for displacement monitoring primarily have an integrated structure for the target panel and base. This means that once the target base is secured to the bearing plane, the orientation angle of the target panel is fixed, requiring the base to be reinstalled to change it. In other words, existing targets cannot flexibly adjust the orientation angle of the target panel, causing inconvenience to personnel and making it difficult to ensure the target panel is within the optimal monitoring field of view of the laser displacement sensor, thereby affecting the displacement monitoring effect of the laser displacement sensor. Utility Model Content

[0003] This application provides a target for displacement monitoring, aiming to improve the existing targets for displacement monitoring, where the target panel and target base are mainly integrated into a single structure, making it impossible to flexibly adjust the orientation angle of the target panel, causing many inconveniences to relevant personnel, or failing to ensure that the target panel is within the optimal monitoring field of view of the laser displacement sensor, thereby affecting the displacement monitoring effect of the laser displacement sensor.

[0004] Therefore, this application provides a target for displacement monitoring, which is used in conjunction with a laser displacement sensor to monitor the displacement of a bearing plane settlement. The target includes a target panel, a connecting rod, and a target base.

[0005] The target panel has a reflective surface that cooperates with the laser displacement sensor to perform displacement monitoring;

[0006] The connecting rod has a first end and a second end. The first end is rotatably mounted on the top of the target base in the vertical direction, and the second end is rotatably mounted on the target panel at least in the horizontal direction.

[0007] The target base is used to be installed on the bearing plane and to fit tightly against the bearing plane.

[0008] Optionally, in some embodiments of this application, the reflective surface is divided into a first reflective area and a second reflective area surrounding the first reflective area, wherein the color of the first reflective area is different from the color of the second reflective area.

[0009] Optionally, in some embodiments of this application, the color of the first reflective area is black, and the color of the second reflective area is white.

[0010] Optionally, in some embodiments of this application, the target panel is an acrylic plate circle, the first reflective area is a circular area, and the second reflective area is an annular area.

[0011] Optionally, in some embodiments of this application, the target further includes at least one supplementary lighting module, and at least one positioning ring is provided on the outer periphery of the target panel, each positioning ring being used for the installation and fixing of the corresponding supplementary lighting module.

[0012] Optionally, in some embodiments of this application, the top end of the target base is provided with a disc mounting groove, and the first end is provided with a rotating disc engraved with an angle gauge. The rotating disc is rotatably mounted in the disc mounting groove in the vertical direction via a rotating shaft.

[0013] Optionally, in some embodiments of this application, one end of the rotating shaft is provided with an adjustment knob for adjusting the rotation of the rotating shaft.

[0014] Optionally, in some embodiments of this application, the side of the target panel away from the reflective surface is rotatably connected to the second end via a spherical hinge structure, such that the target panel can rotate omnidirectionally relative to the second end, including at least in the horizontal direction.

[0015] Optionally, in some embodiments of this application, the target base includes a square base plate and a cylindrical connecting rod. The square base plate has multiple bolt mounting holes so that when the bottom side plane of the square base plate is in close contact with the bearing plane, the square base plate is fastened to the bearing plane by multiple expansion bolts. The bottom end of the cylindrical connecting rod is integrally formed with the top side plane of the square base plate, and the top end of the cylindrical connecting rod is rotatably mounted with the connecting rod in the vertical direction.

[0016] Optionally, in some embodiments of this application, the target further includes an alarm device, which is installed on the target base and is used to provide an audible and visual alert when the laser displacement sensor detects that the displacement of the target is greater than a preset threshold.

[0017] The target for displacement monitoring provided in this application, through the aforementioned structural design, allows the target panel to rotate in multiple directions relative to the target base. This enables flexible adjustment of the orientation angle of the target panel (specifically, the reflective surface), facilitating operation by relevant personnel while ensuring the target panel is within the optimal monitoring field of view of the laser displacement sensor, thereby ensuring the displacement monitoring effect of the laser displacement sensor. Therefore, this technical solution effectively addresses the technical problem of existing targets for displacement monitoring, where the target panel and target base are primarily integrated, making it impossible to flexibly adjust the orientation angle of the target panel. This causes inconvenience to relevant personnel and fails to ensure the target panel is within the optimal monitoring field of view of the laser displacement sensor, thus affecting the displacement monitoring effect of the laser displacement sensor.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0025] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art.

[0026] In one embodiment, such as Figure 1 As shown in the illustration, this application embodiment also provides a target 1, which specifically includes a target panel 100, a connecting rod 200, and a target base 300. The target panel 100 has a reflective surface 110 for displacement monitoring in conjunction with a laser displacement sensor. The connecting rod 200 has a first end 210 and a second end 220. The first end 210 is rotatably mounted on the top of the target base 300 in the vertical direction, and the second end 220 is rotatably mounted on the target panel 100 at least in the horizontal direction. The target base 300 is mainly used for mounting on a bearing plane and is in close contact with the bearing plane.

[0027] It is understood that the target 1 in this embodiment is mainly used in conjunction with a laser displacement sensor to monitor the displacement of the bearing plane settlement. Specifically, in a static load test of the foundation, by fastening the target 1 to the corresponding bearing plane and adjusting the orientation angle of the target panel 100, the displacement change of the target 1 is observed through the corresponding laser displacement sensor, thereby monitoring the displacement of the corresponding bearing plane settlement. The aforementioned "first end 210 rotatably mounted on the top of the target base 300 in the vertical direction" specifically refers to the fact that the first end 210 of the connecting rod 200 can rotate vertically relative to the top of the target base 300. The aforementioned "second end 220 rotatably mounted on the target panel 100 in at least the horizontal direction" specifically refers to the fact that the target panel 100 can rotate at least horizontally relative to the second end 220 of the connecting rod 200.

[0028] In this way, the target 1 provided in this embodiment of the application, through the above-mentioned structural setting, allows its target panel 100 to rotate in multiple directions relative to the target base 300, so that the orientation angle of its target panel 100 (specifically the reflective surface 110) can be flexibly adjusted, which facilitates the operation of relevant personnel while ensuring that the target panel 100 is within the optimal monitoring field of view of the laser displacement sensor, thereby ensuring the displacement monitoring effect of the laser displacement sensor.

[0029] In some examples, such as Figure 1 As shown, the reflective surface 110 is divided into a first reflective area 111 and a second reflective area 112 surrounding the first reflective area 111. The color of the first reflective area 111 is different from the color of the second reflective area 112. This difference in color between the first reflective area 111 and the second reflective area 112 increases the contrast between the different reflective areas on the reflective surface 110, effectively preventing strong light interference. Furthermore, the first reflective area 111 is black, and the second reflective area 112 is white. This structural arrangement maximizes the contrast between the first reflective area 111 and the second reflective area 112, thus minimizing strong light interference. Further, the target panel 100 is a circular acrylic sheet, with the first reflective area 111 being a circular region and the second reflective area 112 being a ring-shaped region. This structural arrangement further reduces strong light interference during high-temperature operation by utilizing the material properties of the acrylic sheet itself. On the other hand, the circular target panel 100 can be used to achieve more comprehensive displacement monitoring.

[0030] Understandably, when the target panel 100 in this example is specifically an acrylic sheet circle, since acrylic sheets are generally transparent, on the one hand, particles of the corresponding color can be added during manufacturing to allow different reflective areas to display different colors. On the other hand, different colored films can be deposited on different areas to allow different reflective areas to display different colors.

[0031] In some examples, such as Figure 1 As shown, the target 1 also includes at least one supplementary lighting module (not shown), and at least one positioning ring 120 is provided on the outer periphery of the target panel 100. Each positioning ring 120 is used for the installation and fixation of the corresponding supplementary lighting module. In this way, with the above structural arrangement, the supplementary lighting of the supplementary lighting module can enable the target 1 to achieve good nighttime positioning and identification even at night.

[0032] In some examples, such as Figure 1As shown, the top of the target base 300 is provided with a disc mounting groove 11, and the first end 210 is provided with a rotating disc 211 engraved with an angle gauge. The rotating disc 211 is vertically mounted in the disc mounting groove 11 via a rotating shaft. Thus, with the above structural arrangement, the first end 210 of the connecting rod 200 and the top of the target base 300 can be rotated vertically relative to the disc mounting groove 11 by rotating the rotating disc 211 with the rotating shaft. Furthermore, one end of the rotating shaft is provided with an adjustment knob to adjust the rotation of the shaft. Thus, with the above structural arrangement, relevant personnel can easily rotate the corresponding adjustment knob, in conjunction with the scale on the rotating disc 211, to rotate the connecting rod 200 and record the rotation angle, thereby effectively adjusting the orientation angle of the reflective surface 110 of the target panel 100.

[0033] In some examples, such as Figure 1 As shown, the side of the target panel 100 away from the reflective surface 110 is rotatably connected to the second end 220 via a spherical hinge structure, allowing the target panel 100 to rotate omnidirectionally relative to the second end 220, including at least the horizontal direction. Thus, through the above structural arrangement, the target panel 100 can rotate omnidirectionally relative to the second end 220, including at least the horizontal direction, via the omnidirectional rotation of the spherical hinge structure.

[0034] In some examples, such as Figure 1 As shown, the target base 300 includes a square base plate 310 and a cylindrical connecting rod 200. The square base plate 310 has multiple bolt mounting holes (not shown) to secure it to the bearing surface using multiple expansion bolts 12 when the bottom surface of the square base plate 310 is tightly fitted to the bearing surface. The bottom end of the cylindrical connecting rod 200 is integrally formed with the top surface of the square base plate 310, and the top end of the cylindrical connecting rod 200 is rotatably mounted with a connecting rod 200 in the vertical direction. This structural design ensures a tight fit between the target base 300 and the bearing surface while providing excellent anchoring.

[0035] In some examples, such as Figure 1 As shown, target 1 also includes an alarm device 440, which is mounted on target base 300 and is used to provide an audible and visual alert when the laser displacement sensor detects that the displacement of target 1 exceeds a preset threshold. Thus, through the above structural design, relevant personnel can easily and promptly obtain information about any abnormal settlement of the current bearing surface.

[0036] It is understood that the alarm device 400 in this example can be connected to the corresponding laser displacement sensor via wired or wireless means to promptly detect any settlement anomalies on the bearing plane corresponding to the current target 1.

[0037] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the inventive concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
