Description

Technical Field

[0001] The utility model relates to the technical field of roadbed deformation monitoring, in particular to a roadbed deformation monitoring device. Background Art

[0002] Roadbed deformation usually refers to the deformation of the roadbed caused by various reasons during use. This deformation may cause the road surface to be uneven or the overall structure to be unstable, affecting the safety and comfort of road use. Therefore, the roadbed settlement deformation is generally monitored before construction.

[0003] Currently, detection is basically carried out directly using settlement plates and distance sensors, which are not stable enough and easily cause monitoring errors. In addition, traditional roadbed deformation monitoring devices are inconvenient to move after they are arranged and cannot meet actual usage needs. Utility Model Content

[0004] The utility model aims to provide a roadbed deformation monitoring device with high practicality, which effectively solves the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions.

[0006] A roadbed deformation monitoring device comprises a base, an inner cavity is provided in the base, four top corners of the inner cavity are respectively fixed with vertically extending guide rods, a mounting plate is slidably sleeved on the four guide rods, four plug piles are evenly distributed on the lower surface of the mounting plate, through holes for the plug piles to pass through are respectively provided at positions corresponding to the positions of the four plug piles on the bottom surface of the base, a first adjusting mechanism for driving the mounting plate to be lifted and lowered is provided on one side of the base, a vertically extending shaft is rotatably installed on the top of the base, a monitoring mechanism is installed on the top of the shaft, and a second adjusting mechanism for driving the shaft to be rotated and adjusted is provided on the top of the base.

[0007] It can be seen that by operating the first adjustment mechanism, the mounting plate is driven to slide downward, thereby driving the four piles to extend through the through holes to the bottom of the base. The four piles are inserted under the soil layer to achieve a fixing effect, thereby reinforcing the base and the components thereon as a whole, and improving the stability of the monitoring mechanism during monitoring.

[0008] Furthermore, running wheels are respectively installed at the four top corners of the bottom of the base, and all four running wheels are all-terrain wheels, and at least two of the running wheels have braking effect.

The mounting seat is fixed on the top of the shaft rod, the hollow rod is fixed on the side of the mounting seat and extends horizontally, the damping guide rail is arranged inside the hollow rod and extends along the length direction of the hollow rod, the sliding slat is slidably and telescopically installed in the hollow rod through the damping guide rail, and the distance sensor is fixed on the lower surface of the sliding slat.

[0010] Furthermore, there are at least three distance sensors, and the distance sensors are arranged at intervals on the lower surface of the sliding strip along the length direction of the sliding strip.

[0011] Furthermore, the first adjustment mechanism includes a threaded rod, a nut seat and a pair of first brackets. One side of the base is provided with a through groove that penetrates the inner cavity, and the through groove extends vertically. The two first brackets are fixed to the side of the base and are respectively located above and below the through groove. The threaded rod is rotatably installed on the two first brackets.

[0012] Furthermore, the second adjustment mechanism includes a worm, a worm wheel and a pair of second brackets. The two second brackets are fixed on the top of the base. The worm is rotatably mounted on the two second brackets. The worm wheel is fixedly sleeved on the shaft and meshes with the worm. A rocker is installed at one end of the worm.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows.

[0014] 1. The utility model drives the mounting plate to slide downward by operating the first adjusting mechanism, thereby driving the four piles to extend through the through holes to the bottom of the base. The four piles are inserted under the soil layer to achieve a fixing effect, thereby reinforcing the base and the components thereon as a whole, and improving the stability of the monitoring mechanism during monitoring.

[0015] 2. The utility model installs traveling wheels at the bottom of the base to facilitate the movement of the entire device and increase the flexibility of the device. In addition, the traveling wheels are all-terrain wheels, which can move normally on the soil surface and adapt to complex terrain. At the same time, the traveling wheels have a braking effect, which can assist the device to be stationary to ensure stability.

[0016] 3. The utility model drives the worm to rotate by shaking the shaking plate. The rotating worm can engage the driving worm wheel and drive the shaft to rotate, thereby driving the monitoring mechanism to rotate and adjust. When the pile is inserted into the soil layer, the monitoring position can be adjusted without dismantling and resetting, thereby meeting actual use needs.

[0017] 4. The utility model can expose the distance sensor to the outside by sliding the sliding slat outward, which is convenient for monitoring. After the work is completed, the distance sensor can be driven to move into the hollow rod by retracting the sliding slat into the hollow rod to achieve the storage of the distance sensor. In addition, the damping guide rail can provide a damping effect for the adjustment of the sliding slat to prevent the sliding slat from sliding randomly and affecting the accuracy of monitoring. In addition, by extending the sliding slat to different amounts, the roadbed within different ranges can be monitored. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-Figure 4The utility model provides a roadbed deformation monitoring device, including a base 1, an inner cavity 11 is provided in the base 1, and vertically extending guide rods 12 are fixed at the four top corners of the inner cavity 11 respectively, and a mounting plate 13 is slidably sleeved on the four guide rods 12 together, and four plug piles 14 are evenly distributed on the lower surface of the mounting plate 13. Through holes 15 for the plug piles 14 to pass through are respectively provided at the positions corresponding to the positions of the four plug piles 14 on the bottom surface of the base 1, and a first adjusting mechanism 2 for driving the mounting plate 13 to be lifted and lowered is provided on one side of the base 1, a vertically extending shaft rod 3 is rotatably installed on the top of the base 1, and a monitoring mechanism 4 is installed on the top of the shaft rod 3, and a second adjusting mechanism 5 for driving the shaft rod 3 to be rotated and adjusted is provided on the top of the base 1.

[0025] When using this monitoring device to monitor roadbed deformation, the base 1 is placed on the roadbed at the monitoring site, and the first adjustment mechanism 2 is operated to drive the mounting plate 13 to slide downward, thereby driving the four plug piles 14 to extend through the through holes 15 to the bottom of the base 1. The four plug piles 14 are inserted under the soil layer to achieve a fixing effect, and the base 1 and the components thereon are reinforced as a whole, thereby improving the stability of the monitoring mechanism 4 during monitoring. After the monitoring is completed, the first adjustment mechanism 2 is operated to drive the mounting plate 13 to slide upward, and the mounting plate 13 drives the four plug piles 14 to move upward and reset to the inner cavity 11 to achieve a storage effect.

[0026] Specifically, walking wheels 101 are respectively installed at the four top corners of the bottom of the base 1. The four walking wheels 101 are all-terrain wheels, and at least two of the walking wheels 101 have braking effects. The walking wheels 101 are installed at the bottom of the base 1 to facilitate the movement of the entire device and increase the flexibility of the device. In addition, the walking wheels 101 are all-terrain wheels, which can walk normally on the soil surface and adapt to complex terrain. At the same time, the walking wheels 101 have braking effects, which can assist the device to be stationary to ensure stability.

[0027] In addition, it is worth mentioning that in the present application, when the mounting plate 13 drives the pile 14 to move downward to the extreme position, the bottom end of the pile 14 is lower than the running wheel 101, thereby ensuring that the pile 14 can be smoothly inserted under the soil layer.

[0028] Specifically, the monitoring mechanism 4 includes a mounting seat 41, a hollow rod 42, a damping guide rail 43, a sliding slat 44 and a distance sensor 45. The mounting seat 41 is fixed to the top of the shaft rod 3, the hollow rod 42 is fixed to the side of the mounting seat 41 and extends horizontally, the damping guide rail 43 is arranged inside the hollow rod 42 and extends along the length direction of the hollow rod 42, the sliding slat 44 is slidably and telescopically installed in the hollow rod 42 through the damping guide rail 43, and the distance sensor 45 is fixed to the lower surface of the sliding slat 44. By moving the sliding slat 44 By sliding and pulling it outward, the distance sensor 45 can be exposed to the outside, which is convenient for monitoring. After the work is completed, the distance sensor 45 can be driven to move into the hollow rod 42 by retracting the sliding slat 44 into the hollow rod 42, so that the distance sensor 45 can be stored. In addition, the damping guide rail 43 can provide a damping effect for the adjustment of the sliding slat 44 to prevent the sliding slat 44 from sliding randomly and affecting the accuracy of monitoring. In addition, by extending the sliding slat 44 by different amounts, the roadbed within different ranges can be monitored.

[0029] Specifically, there are at least three distance sensors 45, and each distance sensor 45 is arranged at intervals on the lower surface of the sliding slat 44 along the length direction of the sliding slat 44, and multiple distance sensors 45 are arranged in an array under the sliding slat 44. The distance sensors 45 can be used to monitor the settlement of the foundation in real time, and the settlements monitored by each distance sensor 45 are added and averaged to make the monitoring result more accurate, thereby avoiding quality problems of a sensor itself and causing inaccurate measurement.

[0030] Specifically, the first adjustment mechanism 2 includes a threaded rod 22, a nut seat 23 and a pair of first brackets 21. One side of the base 1 is provided with a through groove 201 that penetrates the inner cavity 11, and the through groove 201 extends vertically. The two first brackets 21 are fixed to the side of the base 1 and are respectively located above and below the through groove 201. The threaded rod 22 is rotatably installed on the two first brackets 21. The nut seat 23 is threadedly matched and sleeved on the threaded rod 22, and extends into the inner cavity 11 through the through groove 201, and is fixedly connected to the side of the mounting plate 13. A rotary handle 24 is installed at the top of the threaded rod 22. By holding the rotary handle 24 to screw the threaded rod 22, the rotating threaded rod 22 threadably drives the nut seat 23 and drives the mounting plate 13 to slide upward or downward in the inner cavity 11, providing drive for the lifting and lowering adjustment of the mounting plate 13.

[0031] Specifically, the second adjustment mechanism 5 includes a worm 52, a worm wheel 53 and a pair of second brackets 51. The two second brackets 51 are fixed on the top of the base 1. The worm 52 is rotatably mounted on the two second brackets 51. The worm wheel 53 is fixedly sleeved on the shaft 3 and meshes with the worm 52 accordingly. A rocking plate 54 is installed at one end of the worm 52. The worm 52 is driven to rotate by rocking the rocking plate 54. The rotating worm 52 can mesh with the worm wheel 53 and drive the shaft 3 to rotate, thereby driving the monitoring mechanism 4 to rotate and adjust. When the pile 14 is inserted into the soil layer, the monitoring position can be adjusted without dismantling and resetting, thereby meeting actual usage needs.

[0032] The above is a detailed description of the utility model in combination with specific embodiments, and it cannot be determined that the specific implementation methods of the present invention are limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, making several equivalent substitutions or obvious modifications without departing from the concept of the present invention, and having the same performance or use, should be regarded as belonging to the patent protection scope of the utility model determined by the submitted claims.
