Description

Technical Field

[0001] The utility model relates to the technical field of roadbed settlement detection, and more specifically to a roadbed settlement detection device. Background Art

[0002] During the road construction process, roadbed settlement observation is a very important part. By observing roadbed settlement, possible problems can be discovered and solved in time to ensure the quality and safety of road construction. In order to facilitate the detection of roadbed settlement, a roadbed settlement detection device is required, that is, a roadbed settlement plate. It is generally used in conjunction with a level to measure the initial coordinates and the final coordinates, and then the roadbed settlement is calculated through two points.

[0003] Existing road subsidence detection devices are usually placed directly on the roadbed coordinate points for use. Although they are easy to use, they have a simple structure and poor adjustment ability, making it inconvenient to adjust the level. If the device is tilted during coordinate measurement in conjunction with a level, it will affect the accuracy of the roadbed settlement detection. We propose a road subsidence detection device.

When the device is placed at the roadbed detection point, the top plate can be rotated at any angle within a certain range through the rotating structure. Then, by observing the circular level on the top plate, the top seat is adjusted to a horizontal state. Then, the top plate is horizontally fixed by screwing the fixing screws at the four corners of the top plate, thereby completing the horizontal adjustment of the mounting rod and the detection end, ensuring that the mounting rod is in a horizontal state, thereby ensuring the accuracy of the external level instrument in detecting the roadbed settlement through the device, and solving the technical problem that the current roadbed settlement detection device is not convenient for horizontal adjustment and placement. Therefore, the utility model has the advantage of horizontal adjustment and placement.

[0025] like Figures 1 to 6 As shown, the utility model relates to a road subgrade settlement detection device, comprising a base 1, the base 1 comprises a bottom plate 2, a rotating structure 3 is arranged at the top center of the bottom plate 2, a top plate 4 is arranged at the top of the rotating structure 3, four corners of the top plate 4 are screwed with fixing screws 401, a circular level 403 is arranged at the top of the base 1, a mounting rod 7 is movably arranged at the top center of the top plate 4 through a screw sleeve 402, a detection terminal 701 is arranged at the top of the mounting rod 7, when the device is placed at the road subgrade detection point, the top plate 4 can be rotated at any angle within a certain range by the rotating structure 3, and then the top base 4 can be adjusted to a horizontal state by observing the circular level 403 on the top plate, and then the top plate 4 can be horizontally fixed by screwing the fixing screws 401 at the four corners of the top plate 4, that is, the horizontal adjustment of the mounting rod 7 and the detection terminal 701 is completed, and the mounting rod 7 is ensured to be in a horizontal state, so as to ensure the accuracy of the road subgrade settlement detection by the external level through the device;

[0026] Specifically, fixed piles 201 are arranged at the four corners of the bottom of the base plate 2, and the fixed piles 201 are evenly arranged with a plurality of groups of barbs 202. The base plate 2 is fixed to the roadbed through the fixed piles 201. The barbs 202 can firmly grasp the soil to ensure the stability of the fixed piles 201 inserted into the soil.

[0027] Furthermore, the rotating structure 3 includes a ball sleeve 301, the top of the ball sleeve 301 is an opening 302, and a sphere 303 is movably arranged inside the ball sleeve 301; a base 305 is arranged at the bottom of the ball sleeve 301, and the base 305 is arranged at the top center of the bottom plate 2; a connecting terminal 304 is arranged on the top of the sphere 303, and the top end of the connecting terminal 304 is connected to the bottom center of the top plate 4. The connecting terminal 304 at the top of the sphere 303 can be rotated in the opening 302, so as to realize the rotation adjustment of the top plate 4, so that the top plate 4 can be quickly rotated and adjusted to a horizontal state.

[0028] In an embodiment of the utility model, a mounting seat 5 is arranged on one side of the rotating structure 3, and a pre-fixing structure 6 is arranged in the mounting seat 5. When the top plate 4 is rotated to be horizontal, the rotating structure 3 can be fixed by the pre-fixing structure 6, thereby realizing the horizontal pre-fixation of the top plate 4. Therefore, it is convenient for subsequent personnel to fix the top plate 4 by screwing the four sets of fixing screws 401, thereby avoiding the situation where the top plate 4 is easily tilted again by directly screwing the four sets of fixing screws 401 after the top plate 4 is horizontal.

[0029] Specifically, the mounting seat 5 includes a threaded pipe seat 501 and a storage pipe seat 502. The storage pipe seat 502 is arranged through the ball sleeve 301. The threaded pipe seat 501 is arranged on one side of the storage pipe seat 502. The threaded pipe seat 501 and the storage pipe seat 502 are combined to form a T shape. The threaded pipe seat 501 is used for screwing the fixing bolt 601, and the storage pipe seat 502 facilitates the hidden storage of the top fixing block 602.

[0030] Furthermore, the pre-fixing structure 6 includes a fixing bolt 601, which is screwed into the threaded pipe seat 501. One end of the fixing bolt 601 is rotatably arranged with a top fixing block 602 through a bearing. The top fixing block 602 is located inside the storage pipe seat 502. The side of the top fixing block 602 facing away from the fixing bolt 601 is an arcuate surface 603, and the arcuate surface 603 matches the surface of the sphere 303. By screwing the fixing bolt 601, the top fixing block 602 can be driven to move forward, and then the arcuate surface 603 of the top fixing block 602 can be firmly fitted on the sphere 303, thereby fixing the sphere 303. At this time, the top plate 4 cannot rotate, that is, the pre-fixing effect of the top plate 4 is achieved.

[0031] Furthermore, a limiting groove 503 is provided on the inner wall of the storage tube seat 502, and a limiting protrusion 604 symmetrical to the limiting groove 503 is arranged around the top fixing block 602. With the cooperation of the limiting groove 503 and the limiting protrusion 604, the top fixing block 602 moves horizontally without rotating, thereby ensuring the stability of the top fixing block 602 in fixing the ball 303.

[0032] Working principle: This embodiment provides a road subgrade settlement detection device. When in use, first, after placing the device at the subgrade detection point, the top plate 4 can be rotated at any angle within a certain range by the rotating structure 3, and then the top seat 4 is adjusted to a horizontal state by observing the circular level 403 on the top plate, and then the top plate 4 is horizontally fixed by screwing the fixing screws 401 at the four corners of the top plate 4, that is, the horizontal adjustment of the mounting rod 7 and the detection end 701 is completed, ensuring that the mounting rod 7 is in a horizontal state, thereby ensuring the accuracy of the external level instrument in detecting the subgrade settlement through the device;

[0033] Secondly, when the top plate 4 rotates to be horizontal, screwing the fixing bolt 601 can drive the top fixing block 602 to move forward, and then the arc surface 603 of the top fixing block 602 can fit firmly against the sphere 303, thereby fixing the sphere 303. At this time, the top plate 4 cannot rotate, that is, the pre-fixing effect of the top plate 4 is achieved. Therefore, it is convenient for subsequent personnel to screw the four sets of fixing screws 401 separately, so that the bottom ends of them can be pressed against the bottom plate 2 to cooperate with the top plate 4 for stability, thereby avoiding the situation that the top plate 4 is easily deflected again due to directly screwing the four sets of fixing screws 401 after the top plate 4 is horizontal.
