[0026] The racks are all provided with adjustment components, and measuring rulers 4 are provided between the adjustment components for use therewith. The adjustment components are used to display the changing length and angle of the cracks in real time, so as to cope with the multi-angle changes of the cracks, thereby monitoring the changes and displaying them intuitively, so as to facilitate the inspection personnel to record, and then facilitate timely adjustments and repairs, which can effectively avoid greater losses.

[0028] This embodiment further illustrates the technology. Figure 1 As shown, the storage rack includes two fixed plates 2 distributed vertically, a column 6 is vertically fixed between the two fixed plates 2, and the center of the column 6 is perpendicular to the center of the fixed plate 2. The adjustment component is located between the two fixed plates 2, which is convenient for use and also convenient for protecting the adjustment component to extend its service life.
[0029] Example 3
[0030] This embodiment further illustrates the technology. Figure 1 , Figure 2 , Figure 3 and Figure 8As shown, the adjustment assembly includes a sphere 8, the upper and lower ends of the sphere 8 are fixed to the fixed plate 2 by a connecting rod 7, and the sphere 8 and the connecting rod 7 are freely rotatable left and right, and a left-right communicating channel is opened on the sphere 8, and a fixed tube 5 is installed in the channel to swing up and down with the sphere 8, and the measuring ruler 4 is installed in the fixed tube 5 to slide left and right, and a first scale line 9 for displaying the length is provided on the measuring ruler 4, so as to display the changed length when the crack changes horizontally;
[0031] The outer wall of the sphere 8 is provided with a measuring component. When the sphere 8 swings up and down, the measuring component displays the swing degree on the sphere 8, so as to display the settlement amplitude when the crack changes in the vertical direction, thereby monitoring the crack more accurately, making the monitoring data more referenceable and facilitating timely adjustment;
[0032] The connecting rod 7 is connected to the ball 8 through the bearing 11, so that the ball 8 can freely rotate in the left and right directions between the connecting rods 7;
[0033] The measuring ruler 4 is provided with slide grooves on both the front and rear sides, and the front and rear inner walls of the fixed tube 5 are provided with sliders inserted into the slide grooves, and the length of the sliders is consistent with the length of the fixed tube 5;
[0034] A limit plate is fixed at one end of the two measuring rulers 4 to prevent the measuring ruler 4 from falling off the fixed tube 5, and when the measuring ruler 4 is installed in the fixed tube 5, the limit plate is located in different directions, so that the value is more accurate when monitoring the changing length of the crack.
[0035] Example 4
[0036] This embodiment further illustrates the technology. Figure 2 and Figure 7 As shown, the center of the column 6 is perpendicular to the center of the fixed plate 2, and adjustment components are provided between the fixed plates 2 on the front and rear sides of the column 6, and the adjustment components are symmetrically distributed along the column 6, so that it is more stable during monitoring, thereby making the monitoring data more accurate; the adjustment component in this embodiment has the same structure as the adjustment component in Example 3.
[0037] Example 5
[0038] This embodiment further illustrates the technology. Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the measuring assembly includes a pointer 10, and the front and rear sides of the fixed tube 5 swing up and down with the sphere 8 through a connecting rod 12, and the connecting rod 12 is arranged at the center of the fixed tube 5, so that the lengths of the two ends of the fixed tube 5 are consistent and more stable, thereby making the detection data more accurate;
[0039] One end of the connecting rod 12 passes through the sphere 8 and is connected to a pointer 10, and a second scale line 13 for displaying degrees is provided on the outer wall of the sphere 8 corresponding to the pointer 10, so as to display the degree of settlement when the crack settles slightly, thereby facilitating the judgment of the development direction of the crack and making timely adjustments to reduce the impact that the crack may cause;
[0040] In combination with Example 3, the connecting rod 12 also swings up and down with the sphere 8 through the bearing, and the bearing connecting the connecting rod 12 and the sphere 8 is not shown in the figure.
[0041] Example 6
[0042] This embodiment further illustrates the technology. Figure 2 and Figure 5 As shown, the pointer 10 is an arc-shaped structure as a whole, and a gap is left between the inner wall of the pointer 10 and the sphere 8, so as to more intuitively display the settlement degree of the crack, which not only reduces the difficulty of the work of the inspectors, but also avoids the influence of judgment on data recording errors caused by unclear display.
[0043] Example 7
[0044] This embodiment further illustrates the technology. Figure 1 and Figure 4 As shown, a plurality of fixed blocks 14 are evenly arranged on the top of the measuring ruler 4, and the fixed blocks 14 are fixed on the long scale line of the first scale line 9, and a stopper 15 used in conjunction with the fixed block 14 is arranged on the top of the fixed tube 5, and the length of the stopper 15 is equal to the distance from the top of the fixed block 14 to the top of the fixed tube 5, and the stopper 15 is made of elastic material, which is convenient for slightly blocking the measuring ruler 4, thereby preventing the measuring ruler 4 from sliding arbitrarily in the fixed tube 5 and affecting the accuracy of the detection data;
[0045] The fixing block 14 is arranged on the long scale line and, when used in conjunction with the stopper 15, also plays a more obvious role, allowing the observer to read the value more quickly;
[0046] The length of the stopper 15 is determined by the selected material, and its maximum length is less than the distance from the top of the fixed tube 5 to the top of the measuring ruler 4, which can block the fixed block 14 to prevent the measuring ruler 4 from sliding easily and prevent the measuring ruler 4 from being unable to slide;
[0047] The scale lines are usually set on a ruler or other measuring tools. The names of the scale lines are mainly determined according to their functions and the units they represent, and generally include the 0 scale line, the long scale line, the short scale line and the scale unit; the 0 scale line is also called the starting line, which is usually the leftmost or bottommost scale line and is used to indicate the starting point of the measurement; the long scale line is also called the main scale line or the whole scale line, which usually represents larger units, such as centimeters or inches. On a ruler, they are usually longer lines for quick identification;
[0048] Also called short or sub-marks, these marks represent small units between the main marks. On a centimeter ruler, they usually represent millimeters. These marks are usually shorter than the main marks, but distinct enough to read the short marks.
[0049] Scale units refer to the units of length or angle represented by the scale lines, such as millimeters, centimeters, inches and degrees.
[0050] Example 8
[0051] This embodiment further illustrates the technology. Figure 1 and Figure 4 As shown, there are at least two blocks 15 located at the left and right ends of the top of the fixed tube 5, and the outer wall of the fixed block 14 is a smooth surface, which is convenient for further increasing the stability of the measuring ruler 4 and avoiding the position of the measuring ruler 4 from changing when the crack has not changed but there is slight vibration in the surrounding environment.
[0052] Example 9
[0053] This embodiment further illustrates the technology. The fixed block 14 is made of transparent glass material, and the fixed block 14 as a whole is a convex lens structure, which is convenient for amplifying the value on the first scale line 9, making it easier for patrol personnel to read out the value for recording.
[0054] Example 10
[0055] This embodiment further illustrates the technology. Figure 1 As shown, both ends of the channel are trumpet-shaped structures, and their diameter gradually decreases from the outer opening to the inside, so that the swing amplitude of the fixed tube 5 is larger, and the sphere 8 drives the fixed tube 5 to rotate with a larger amplitude, thereby facilitating a larger monitoring range for cracks and making the monitoring data more accurate to a certain extent.
[0056] Working principle: first fix the bottom plate 1 on both sides of the crack through the fixing rod 3, then install the measuring ruler 4 in the fixing tube 5. After installation, record the value of the fixing tube 5 on the measuring ruler 4 and the position of the pointer 10 on the second scale line 13. When the crack changes horizontally to the left and right, it will drive the bottom plate 1 on one side to move, so that the measuring ruler 4 slides in the fixing tube 5.
[0057] When the crack changes horizontally forward and backward, it drives the ball 8 to rotate, and at the same time drives the measuring ruler 4 to slide in the fixed tube 5;
[0058] When the crack settles in the vertical direction, it will drive the fixed tube 5 to swing up and down, and at the same time make the measuring ruler 4 slide in the fixed tube 5;
[0059] The inspector records the value of the fixed pipe 5 corresponding to the first scale line 9 on the measuring ruler 4 and the value of the pointer 10 corresponding to the second scale line 13, and then calculates with the initial value to obtain the change of the crack.
