Description

Technical Field

[0001] This invention relates to a measuring device, specifically a measuring device for rubber bearing defects. Background Technology

[0002] At present, the methods for detecting defects in bridge rubber bearings are relatively simple and inefficient. Most of the time, they rely on steel tape measures, steel rulers, or feeler gauges, and rely on manual close-range measurement and data collection based on the type of defect. This is greatly affected by the surrounding environment and the sense of responsibility of the data collectors, resulting in low accuracy of the test data. When there are many bearings and defects, most of the data are estimated by the operators based on their experience, and the data obtained by different people vary greatly.

[0003] Historical data shows that most bearing defects are described using vague terms, and the data is not detailed or lacks detailed data on certain defects. Due to the lack of relevant quantitative data, it is impossible to continuously quantify and compare the degree of bearing defect development.

[0004] The invention application number is 202111478949.9. It is a convenient tool for detecting cracks on rubber surfaces. The invention mainly integrates a right-angle ruler, a first position detection module, a second position detection module, a controller and a display module into one unit. By operating the controller, the horizontal and vertical sliding positions of the first and second position detection modules are adjusted to measure and delineate more cracks in the detection area. The crack length is measured by the scale lines on the right-angle ruler. The invention has the following limitations: (1) It is greatly affected by the support detection space and is more suitable for large-size supports; (2) The crack length measurement range is small and cannot meet the needs of cracks with a length of ten or twenty centimeters at one time. It requires multiple horizontal movements to complete the measurement; (3) It cannot measure the width of cracks on the support surface or can not directly measure cracks with a certain tilt angle.

[0005] The utility model patent number ZL 2022 2 0592863.2 is a device for measuring the void area of ​​bridge bearings. This utility model relies on a sliding window on the caliper body to directly measure the void height of the bearing through the void height measuring ruler on the sliding window, and then measures the void depth value of the bearing by rotating the void depth measuring device on one side of the caliper body. The slight drawback of this utility model is that it is also a single defect detection tool for bearings. Summary of the Invention

[0006] The technical problem to be solved by this invention is that it is inconvenient to detect defects in bridge bearings and cracks are not easily displayed through intuitive data.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] First, a device for rapidly measuring defects in bridge rubber bearings is provided, characterized by comprising a caliper body, wherein a first measuring section is provided on the left side of the caliper body for measuring the bearing shear angle, a second measuring section is provided in the middle of the caliper body for measuring radial cracks, a third measuring section and a fourth measuring section are provided on the right side of the caliper body, wherein the third measuring section is used to measure horizontal cracks having a first length, and the fourth measuring section is used to measure horizontal cracks exceeding the first length; and a fifth measuring section and a sixth measuring section are provided on the top of the caliper body for measuring the bearing detachment height and detachment depth, respectively.

[0009] Furthermore, the first measuring unit includes a fan-shaped window with a corresponding circular angle of 120°, used to measure the shear angle between -60° and 60°.

[0010] Furthermore, the second measuring unit includes several crack windows, and the edges of the crack windows are provided with scales.

[0011] Furthermore, the second measuring unit includes a vertical crack window, a crack window tilted at 15° to the left, a crack window tilted at 15° to the right, a crack window tilted at 30° to the left, and a crack window tilted at 30° to the right.

[0012] Furthermore, the third measuring unit includes a first rectangular window with a scale, and a first width measuring ruler is slidably connected inside the first rectangular window for measuring the width of a horizontal crack.

[0013] Furthermore, the fourth measuring unit includes a second rectangular window, an extended rectangular frame is slidably connected inside the second rectangular window, scales are provided on the second rectangular window and the extended rectangular frame, and a second width measuring ruler is slidably connected inside the second rectangular window for measuring the width of horizontal cracks.

[0014] Furthermore, the fifth measuring part includes a height measuring scale, and the caliper body has a first sliding groove corresponding to the position of the height measuring scale. A spring is slidably connected to the first sliding groove corresponding to the position of the height measuring scale, and the height measuring scale is rotatably mounted on the end of the spring.

[0015] Furthermore, the sixth measuring part includes a hollow depth measuring scale. A second sliding groove is formed at the position of the caliper body corresponding to the hollow depth measuring scale. The hollow depth measuring scale is slidably connected in the second sliding groove. A rotating shaft is installed at the slidable connection between the hollow depth measuring scale and the second sliding groove to drive the hollow depth measuring scale to rotate.

[0016] Furthermore, a locking device is installed at the rotating shaft to restrict the rotation of the detachment depth measuring scale.

[0017] This invention also provides a method for using a device for rapidly measuring defects in bridge rubber bearings, characterized by comprising the following methods:

[0018] When measuring the shear angle of the support, align the central angle of the sector window with a point on the upper or lower boundary of the support and take the reading.

[0019] When measuring radial cracks, ensure that the radial crack is completely within the corresponding crack window and take the reading.

[0020] When measuring a horizontal crack, the horizontal crack is completely placed within the first rectangular window for reading. When the horizontal crack exceeds the range of the second rectangular window, the second rectangular window and the extended rectangular frame are used for measurement.

[0021] When measuring the height of the support detachment, rotate the detachment depth measuring ruler until it is parallel to the direction of the support detachment, and take the reading.

[0022] When measuring the void depth, rotate the void depth measuring ruler to align it with the void depth direction and take the reading.

[0023] This invention has the following beneficial effects: By setting multiple measuring parts on the caliper body, it can quickly and accurately measure various defects, integrating multiple functions into one, saving costs, and is convenient to carry and operate. When the number of supports is large, it can reduce the workload of the staff, and can quantify different hazards, reducing the interference of subjective factors of the staff, thereby enabling more accurate corresponding treatment, providing a reliable guarantee for the safe operation of the bridge. At the same time, the quantification of defects can effectively analyze the degree and development trend of defects, enabling numerical comparison and deeper analysis, ensuring the stability of the bridge.

[0030] It should be noted that all directional indications in the embodiments of the present invention are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0031] Furthermore, in this invention, descriptions involving "first," "second," etc., are 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. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0032] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0033] This invention provides a device for rapidly measuring defects in bridge rubber bearings, such as... Figure 1 As shown, the device includes a caliper body 1. A first measuring section is provided on the left side of the caliper body 1 for measuring the shear angle of the support 10. A second measuring section is provided in the middle of the caliper body 1 for measuring radial cracks. A third measuring section and a fourth measuring section are provided on the right side of the caliper body 1. The third measuring section is used to measure horizontal cracks with a first length, and the fourth measuring section is used to measure horizontal cracks with a length exceeding the first length. A fifth measuring section and a sixth measuring section are provided on the top of the caliper body 1 for measuring the height and depth of the support 10 being detached, respectively.

[0034] Specifically, in this embodiment, the handheld caliper body 1 measures the defects of the support 10. When the support 10 undergoes shear deformation during long-term use, the first measuring part of this device can be used to measure the shear angle, and the tilt angle of the support 10 can be measured. When radial cracks appear on the side of the support 10, the second measuring part can be aligned with the radial crack, and the length and width of the radial crack can be measured through the second measuring part. For horizontal cracks, the third and fourth measuring parts can be used for measurement. The range of the fourth measuring part exceeds that of the third measuring part, so when the length of the horizontal crack is within the range of the third measuring part, it can be measured using either the third or fourth measuring part. When the crack length exceeds the range of the third measuring part, it can be measured using the fourth measuring part. When the rubber on the support 10 falls off, a void is formed, and the void height and void depth can be measured using the fifth and sixth measuring parts.

[0035] like Figure 1 and Figure 3 As shown, the first measuring unit includes a sector window 2, which corresponds to a circular angle of 120° and is used to measure the shear angle between -60° and 60°.

[0036] Specifically, in this embodiment, in order to measure the shear angle of the support 10, a certain point on the support 10 is selected as a temporary reference point and coincides with the dot of the fan-shaped window 2. Then, the edge of the shear direction and the corresponding scale on the fan-shaped window 2 are found to obtain the shear angle of the support 10. Since the angle between -60° and 60° is selected for the fan-shaped window 2, supports tilted in different directions can be measured.

[0037] like Figure 1 As shown, the second measuring unit includes several crack windows 3, and the edges of the crack windows 3 are provided with scales. The second measuring unit includes a vertical crack window, a crack window tilted at 15° on the left, a crack window tilted at 15° on the right, a crack window tilted at 30° on the left, and a crack window tilted at 30° on the right.

[0038] Specifically, in this embodiment, when a radial crack appears in the support 10, the crack may be inclined due to different crack directions, generally between 15° and 30°. Therefore, most inclined radial cracks can be measured by opening crack windows with an inclination of 15° on the left, 15° on the right, 30° on the left, and 30° on the right. By selecting a suitable crack window and placing the crack within the crack window, the length and width of the radial crack can be obtained by reading the scale on the edge of the crack window.

[0039] like Figure 1As shown, the third measuring unit includes a first rectangular window 4 with a scale on it, and a first width measuring ruler 41 slidably connected inside the first rectangular window 4 for measuring the width of a horizontal crack. The fourth measuring unit includes a second rectangular window 5 with an extended rectangular frame 51 slidably connected inside it, and scales on both the second rectangular window 5 and the extended rectangular frame 51. A second width measuring ruler 52 slidably connected inside the second rectangular window 5 for measuring the width of a horizontal crack.

[0040] Specifically, in this embodiment, when measuring a horizontal crack, the horizontal crack is positioned within the first rectangular window 4 or the second rectangular window 5. The length of the horizontal crack can be obtained by reading the scale on the first rectangular window 4 or the second rectangular window 5. The width of the horizontal crack can be obtained by using the first width measuring ruler 41 and the second width measuring ruler 52. When the horizontal crack is long, the extended rectangular frame 51 is pulled to move, increasing the effective length of the second rectangular window 5 and the extended rectangular frame 51 so that they can completely cover the horizontal crack. The length of the horizontal crack can be obtained by reading the scale on the extended rectangular frame 51.

[0041] like Figure 2 and Figure 4 As shown, the fifth measuring part includes a height measuring ruler 6. The caliper body 1 has a first groove 61 at the position corresponding to the height measuring ruler 6. A spring 62 is slidably connected at the position corresponding to the height measuring ruler 6 in the first groove 61. The height measuring ruler 6 is rotatably mounted at the end of the spring 62.

[0042] Specifically, in this embodiment, the first slide groove 61 can be used to easily move the detachment height measuring ruler 6, ensuring that the detachment height can be measured at various positions. During measurement, the detachment height measuring ruler 6 compresses the spring 62, causing the detachment height measuring ruler 6 to extend into the first slide groove 61. At this time, the edge of the caliper body 1 corresponds to the scale on the detachment height measuring ruler 6, which is the value of the detachment height.

[0043] like Figure 2 and Figure 4 As shown, the sixth measuring part includes a hollow depth measuring ruler 7. A second slide groove 71 is opened at the position of the caliper body 1 corresponding to the hollow depth measuring ruler 7. The hollow depth measuring ruler 7 is slidably connected in the second slide groove 71. A rotating shaft is installed at the slidable connection between the hollow depth measuring ruler 7 and the second slide groove 71 to drive the hollow depth measuring ruler 7 to rotate.

[0044] Specifically, in this embodiment, when measuring the delamination depth, the delamination depth measuring ruler 7 is moved or rotated to correspond with the delamination position. Then, the delamination depth can be obtained by reading the scale of the delamination depth measuring ruler 7. For ease of operation, a locking mechanism can be installed at the rotating shaft to lock the delamination depth measuring ruler 7, which makes it convenient to measure and read the value.

[0045] The present invention also provides a method for using a device for rapidly measuring defects in bridge rubber bearings, the method of use being as follows;

[0046] When measuring the shear angle of support 10, align the central angle of the sector window 2 with a point on the upper and lower boundaries of support (10), and then find the scale on the sector window 2 corresponding to the edge of the shear direction of support 10 to obtain the shear angle of support 10.

[0047] When measuring a radial crack, first find the crack window that is aligned with the inclination direction of the radial crack, and make the radial crack completely fall within the corresponding crack window. Then, take a reading of the crack window to obtain the length and width values ​​of the radial crack.

[0048] When measuring a horizontal crack, the horizontal crack is completely placed within the first rectangular window 4, and the reading is taken to obtain the length and width of the horizontal crack within the first length. When the horizontal crack exceeds the range of the first rectangular window 4, the extension rectangular frame 51 is pulled to extend the effective length of the second rectangular window 5 and the extension rectangular frame 51, placing the horizontal crack with a length exceeding the first length within the second rectangular window 5 and the extension rectangular frame 51. The corresponding length and width of the horizontal crack are then obtained by taking the reading.

[0049] When measuring the height of the support detachment, rotate the detachment depth measuring ruler 7 parallel to the direction of the support detachment. The detachment depth measuring ruler 7 compresses the spring 62. At this time, the edge of the caliper body 1 corresponds to the scale on the detachment height measuring ruler 6, which is the height of the support 10 detachment.

[0050] When measuring the void depth, rotate and / or move the void depth measuring scale 7 so that it is aligned with the void depth direction of the support 10. The scale of the void depth measuring scale 7 corresponding to the edge of the support 10 is the void depth.

[0051] It should be understood that the above description of specific embodiments of the present invention is only for illustrating the technical approach and features of the present invention, and is intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. However, the present invention is not limited to the specific embodiments described above. All changes or modifications made within the scope of the claims of the present invention should be covered within the protection scope of the present invention.
