Description

Technical Field

[0001] The invention relates to the technical field of foundation settlement measurement, in particular to a foundation settlement deformation measurement device. Background Art

[0002] Foundation settlement is the deformation caused by the force applied to the road during its use. Roadbed settlement is mainly the compression deformation caused by the force applied to the road during its use. Both foundation settlement and roadbed compression deformation will cause unevenness of the road surface, such as partial or overall collapse of the road, vehicle jumping at the bridge head, road cracks, etc., which will in turn affect the comfort and safety of driving. At present, when detecting the foundation or roadbed settlement of a road, a measuring sensor is usually used to overall reflect the adult settlement of the foundation and roadbed or it is monitored manually.

[0003] A foundation settlement deformation measuring device and a measuring method are disclosed in Chinese patent application No. 202310411363.3. It includes a supporting device and a positioning device. The present invention uses a positioning component to follow the sliding of the slider and translate along the surface of the foundation settlement area. During the movement, its bottom is always in contact with the surface of the foundation settlement area. The surface change trend of the foundation settlement area is fed back by the up and down movement of the positioning component. The height of the surface points of different foundation settlement areas can be obtained by measuring the up and down movement distance of the positioning component. The drawing head is set to keep synchronous movement with the positioning component, and the end of the drawing head is in contact with the side of the drawing surface. During the movement of the drawing head, a mark consistent with its movement trajectory will be left on the drawing surface. This mark is the deformation of the foundation settlement area surface. By forming a mark measurement result on the drawing surface, the change trend of the deformation of the foundation settlement area surface, the highest point height and the lowest point height are obtained, providing a measurement basis for later filling.

[0004] Although the foundation settlement can be measured in this patent, it is measured by a set of positioning components, and the settlement data of a single line is measured, and the foundation settlement of an area cannot be detected. Summary of the invention

When the motor 4 drives the linkage plate 10 to move, the sensors connected to the linkage plate 10 simultaneously detect the foundation, and the linkage plate 10 can detect the entire foundation of the plane it passes through after moving once, thereby avoiding the problem in the prior art that the foundation is measured by a set of positioning components, the settlement data of a single line is measured, and the settlement of the foundation of an area cannot be detected.

[0038] A roller 9 is arranged on the placement rod 8 to make movement during detection more convenient.

[0039] Example 2

[0040] See also Figure 3 On the basis of Example 1, the sensor is connected to the control cabinet 3 via a data cable 13 , and the data cable 13 is connected to the rack 1 via a first limiting component 11 .

[0041] Preferably, the first limiting assembly 11 includes two groups of elastic limiting assemblies 111 and one group of fixed limiting assemblies 112;

[0042] The fixed limiting assembly 112 includes a fixed frame 1121 and a second limiting roller 1122 . The fixed frame 1121 is fixedly connected to the frame 1 , and the second limiting roller 1122 is rotatably connected to the fixed frame 1121 .

[0043] Preferably, the elastic limiting assembly 111 includes a first sliding rod 1111 penetrating the frame 1, and the first sliding rod 1111 is slidably connected to the frame 1, one end of the first sliding rod 1111 away from the frame 1 is fixedly connected to a limiting plate 1113, a first spring 1112 is arranged between the limiting plate 1113 and the frame 1, the first spring 1112 is sleeved on the first sliding rod 1111, and two ends of the first spring 1112 are respectively in contact with the limiting plate 1113 and the frame 1;

[0044] The limiting plate 1113 is fixedly connected to a mounting plate 1114, a side surface of the mounting plate 1114 is fixedly connected to one end of a fixing column 1115, and the other end of the fixing column 1115 is rotatably connected to a first limiting frame 1118;

[0045] A second sliding rod 1116 is connected through the mounting plate 1114, and the second sliding rod 1116 is located above the fixing column 1115. The second sliding rod 1116 is rotatably connected to the first limiting frame 1118. A second spring 1117 is provided between the first limiting frame 1118 and the mounting plate 1114. The second spring 1117 is sleeved on the second sliding rod 1116, and the two ends of the second spring 1117 are respectively abutted against the first limiting frame 1118 and the mounting plate 1114. A first limiting roller 1119 is rotatably connected to the first limiting frame 1118.

[0046] Preferably, the first limiting roller 1119 and the second limiting roller 1122 are both concave in the middle.

[0047] The working principle and beneficial effects of the above scheme:

[0048] During detection, the sensor moves with the linkage plate 10, and the data cable 13 connected between the sensor and the control cabinet 3 moves accordingly. If the data cable 13 is not limited in movement, the data cable 13 may be rolled into the screws 5 or other components, causing damage;

[0049] Several groups of first limiting components 11 are provided to limit the data cable 13, so as to prevent the data cable 13 from being wound between the screws 5 or other components and causing damage, and the provision of the first limiting roller 1119 and the second limiting roller 1122 will not affect the movement of the data cable 13 with the linkage plate 10;

[0050] The first spring 1112 disposed between the two sets of elastic limiting components 111 and the frame 1, and the second spring 1117 disposed between the first limiting frame 1118 and the mounting plate 1114 ensure that the distance between the first limiting roller 1119 and the second limiting roller 1122 can be changed, that is, the effect of the first limiting component 11 will not be affected by the size of the data cable 13;

[0051] When the size of the data cable 13 is large, the data cable 13 squeezes the first limiting roller 1119, and the first limiting roller 1119 drives the first limiting frame 1118 to squeeze the second spring 1117. The first limiting frame 1118 deflects and simultaneously stretches the first spring 1112, thereby increasing the distance between the first limiting roller 1119 and the second limiting roller 1122, thereby ensuring that the data cable 13 passes smoothly.

[0052] Example 3

[0053] See also Figure 4 On the basis of Example 1-2, the sensor is connected to the control cabinet 3 via a data cable 13 , and the data cable 13 is connected to the rack 1 via a second limiting component 12 .

[0054] The second limiting assembly 12 includes two groups of limiting mounting frames 121, one group of the limiting mounting frames 121 is fixedly connected to the frame 1, and a fourth spring 122 and a guide rod 123 are arranged between the two groups of the limiting mounting frames 121. The guide rod 123 is inserted into the limiting mounting frames 121, and the fourth spring 122 is connected to the outer shell of the guide rod 123. The two ends of the fourth spring 122 are in contact with different limiting mounting frames 121.

[0055] Preferably, the limiting mounting frame 121 includes a second limiting frame 1213, the inner side wall of the second limiting frame 1213 is fixedly connected to one end of a third spring 1214, the other end of the third spring 1214 is fixedly connected to a wedge block 1212, and the side surface of the wedge block 1212 can penetrate the second limiting frame 1213;

[0056] The outer wall of the second limiting frame 1213 is rotatably connected to a knob 1217, and the knob 1217 is threadedly connected to a threaded moving rod 1216, one end of the threaded moving rod 1216 is located in the second limiting frame 1213, and one end of the threaded moving rod 1216 located in the second limiting frame 1213 is rotatably connected to a pressing block 1215, and the pressing block 1215 abuts against the wedge block 1212;

[0057] The inner surface of the second limiting frame 1213 is fixedly connected with a column 1211 , and the column 1211 is rotatably connected with a pulley, and the pulley abuts against the inclined surface of the wedge block 1212 .

[0058] The working principle and beneficial effects of the above scheme:

[0059] When the data cable 13 moves with the linkage plate 10, the data cable 13 passes between the two groups of wedge blocks 1212 of the second limit assembly 12. The two groups of wedge blocks 1212 pressurize the data cable 13 with the third spring 1214 and the column 1211, and provide a certain friction force to the data cable 13 when the data cable 13 moves, which further restricts the data cable 13 and prevents the data cable 13 from falling off at other positions.

[0060] By turning the knob 1217, the position of the pressure block 1215 can be adjusted through the threaded moving rod 1216, thereby changing the length of the third spring 1214. Since the length of the column 1211 remains unchanged and the inclined surface of the wedge block 1212 is in contact with the column 1211, the distance by which the wedge block 1212 extends out of the second limit frame 1213 can be changed by adjusting the knob 1217, that is, the pressure of the wedge block 1212 on the data cable 13 can be changed, thereby increasing practicality.

[0061] Example 4

[0062] See also Figure 5Based on the above embodiments 1-3, a stabilizing component 14 is installed on the lower surface of the supporting leg 2.

[0063] Preferably, the stabilizing assembly 14 includes two groups of support plates 141, two groups of fixing rods 142 are connected between the two groups of support plates 141, two groups of sliding sleeves 143 are sleeved on the fixing rods 142, a fifth spring 144 is arranged between the sliding sleeve 143 and the support plates 141, the fifth spring 144 is sleeved on the fixing rod 142, and two ends of the fifth spring 144 are respectively in contact with the sliding sleeve 143 and the support plates 141;

[0065] A sixth spring 148 is disposed between the lower end of the support leg 2 and the support plate 141 , and two ends of the sixth spring 148 are fixedly connected to the support leg 2 and the support plate 141 , respectively.

[0066] Preferably, a synchronization rod 147 is provided between the sliding sleeves 143 on different fixing rods 142 , and both ends of the synchronization rod 147 are fixedly connected to the sliding sleeves 143 .

[0067] The working principle and beneficial effects of the above technical solution are:

[0068] A stabilizing assembly 14 is provided on the supporting leg 2. When the frame 1 is offset, the frame 1 will be in an unstable state. The different forces exerted on the stabilizing assembly 14 by the supporting leg 2 will result in different compression lengths of the fifth spring 144 and the sixth spring 148 of different stabilizing assemblies 14. By compressing the fifth spring 144 and the sixth spring 148 of the stabilizing assembly 14, the frame 1 can be kept in a stable state as much as possible, which is beneficial to the accuracy of foundation settlement detection.
