Description

Technical Field

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

[0002] High ride quality is the key to the smooth and safe operation of highways. However, the problem of roadbed settlement is becoming increasingly prominent, posing a serious threat to the safety and stability of highways. Therefore, monitoring the settlement of highway roadbeds has become an indispensable task in the process of highway construction and maintenance, and timely and accurate monitoring of roadbed settlement has become an important topic in the engineering field.

[0003] With the rapid development of highway construction in my country, the requirements for highway roadbed monitoring devices are getting higher and higher. The current measurement devices cannot meet the current highway development requirements for high efficiency and high accuracy in roadbed settlement measurement.

[0004] For example, a Chinese patent application with the publication number CN117146772A discloses a roadbed settlement monitoring device, in which a measuring rod abutting against the foundation is provided, the measuring rod includes a lower fixed rod and an upper movable rod, one end of the measuring rod is connected to an upper top plate abutting against the ground through the lower fixed rod, when the roadbed settles, the upper top plate and the upper movable rod will slide downward, thereby driving the lower fixed rod and the upper movable rod to slide relative to each other, thereby monitoring the roadbed settlement. The monitoring device provided by the patent monitors the settlement of the roadbed through the relative sliding of the lower fixed rod and the upper movable rod, and after the position change conversion of the two objects including the lower fixed rod and the upper movable rod, it will lead to the problem of low measurement accuracy. Utility Model Content

[0005] The existing roadbed monitoring device still has the problem of low measurement accuracy. In order to solve the above technical problem, the utility model provides a roadbed settlement monitoring device.

[0006] The specific technical solution of the utility model is:

[0007] The utility model provides a roadbed settlement monitoring device, comprising a measuring component, a fixing component, and an installation component;

[0008] The measuring component includes a base plate and a measuring instrument. The mounting component is used to bury the base plate in the roadbed surface and settle with the roadbed. The fixing component is used to fix the measuring instrument at a roadbed observation point that does not settle with the roadbed. The measuring component also includes a linkage rod that fixes the measuring instrument and the base plate, so that the measuring instrument rod moves with the roadbed settlement.

[0009] In the prior art, the measurement of roadbed settlement is performed by converting the movement of multiple objects driven by the roadbed settlement to obtain the settlement measurement result, and the measurement accuracy is poor.

[0010] When the device is used for measurement, the bottom plate is in contact with the foundation. Since the linkage rod is movably connected to the measuring instrument, when the roadbed settles, such as when it sinks, the linkage rod will move away from the measuring instrument under the action of gravity, and the measuring instrument can directly obtain the foundation settlement depth according to the distance of the linkage rod. For example, the measuring instrument is a dial indicator, and a measuring rod is provided on the dial indicator, and the measuring rod is fixedly connected to the linkage rod. When the roadbed sinks, the linkage rod drives the measuring rod to descend, and the sliding value can be displayed on the dial indicator through the descending sliding of the measuring rod. This value is the distance of the linkage rod, that is, the foundation settlement depth.

[0011] Among them, the roadbed observation point is an observation point fixed on the ground surface, which does not settle with the settlement of the roadbed.

[0012] In the roadbed measurement device provided in this embodiment, when the roadbed settles, the linkage rod is driven to move, and the measuring instrument can directly obtain the settlement result according to the movement distance of the linkage rod. It only involves the movement conversion of one object, the linkage rod, and the settlement measurement accuracy is high.

[0013] As a preferred embodiment of the present invention, the measuring instrument is a dial indicator, and a measuring rod is provided on the dial indicator, which is fixedly connected to the linkage rod.

[0014] As a preferred embodiment of the present invention, the fixing component includes a connecting rod fixedly connected to the roadbed observation point; the number of the connecting rods is 2, which are symmetrically fixed on the measuring instrument.

[0015] Further preferably, the fixing component is arranged in the protective box.

[0016] As a preferred embodiment of the present utility model, the roadbed settlement monitoring device also includes an observation component for observing the measurement results.

[0017] Further preferably, the observation component includes a level, which is connected to the measuring instrument and is on the same horizontal line.

[0018] Further preferably, the linkage rod and the base plate are made of aluminum alloy.

[0019] As a preferred embodiment of the utility model, the installation components include a base, a support plate fixedly connected to the base, a threaded sleeve, a motor, and a drill bit; a slide groove is provided on the support plate, and the threaded sleeve is connected to the slide groove; the threaded sleeve is connected to the motor, and the other end of the motor is connected to the drill bit.

[0020] Further preferably, the base includes a threaded rod and a rotating rod arranged on the threaded rod, and the threaded rod is threadably connected to the threaded sleeve.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] (1) In the prior art, the measurement of roadbed settlement is performed by converting the movement of multiple objects driven by the roadbed settlement to obtain the settlement measurement result, and the measurement accuracy is poor. In the roadbed measurement device provided in this embodiment, when the roadbed settles, the linkage rod is driven to move, and the measuring instrument can directly obtain the settlement result according to the movement distance of the linkage rod. It only involves the movement conversion of one object, the linkage rod, and the settlement measurement accuracy is high. At the same time, this embodiment can simplify the monitoring operation and increase the monitoring efficiency.

[0023] (2) Furthermore, in this embodiment, the accuracy of the numerical value is determined by observing the numerical value on the dial indicator with a level instrument and judging the horizontality, which can further improve the accuracy of roadbed settlement monitoring.

[0024] (3) Furthermore, this embodiment adds a fixing component, and the measuring instrument is symmetrically fixed by double connecting rods to connect the measuring instrument to the roadbed settlement monitoring point; and the fixing component is further set in the protective box; at the same time, the utility model also sets the linkage rod and the bottom plate to be made of aluminum alloy. The above settings can effectively prevent the monitoring accuracy from decreasing due to environmental factors, and further improve the roadbed settlement monitoring accuracy.

[0025] Further or more detailed beneficial effects will be described in detail in conjunction with specific examples in the specific implementation manner. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Example 1

[0032] like Figures 1 to 3 As shown, this embodiment provides a roadbed settlement monitoring device, including a measuring component 1, a fixing component 3, and an installation component 2;

[0033] The measuring component includes a base plate and a measuring instrument. The installation component is used to bury the base plate in the roadbed surface and settle with the roadbed. The installation component is used to fix the measuring instrument at a roadbed observation point that does not settle with the roadbed. The measuring component also includes a linkage rod that fixes the measuring instrument and the base plate, so that the measuring instrument rod moves with the roadbed settlement.

[0034] When the device is used for measurement, the base plate 101 is in contact with the foundation. Since the linkage rod 102 and the measuring instrument 103 are movably connected, when the roadbed settles, such as sinking, under the action of gravity, the linkage rod 102 will move away from the measuring instrument 103, and the measuring instrument 103 can directly obtain the foundation settlement depth according to the distance of the linkage rod 102. For example, the measuring instrument 103 is a dial indicator, and a measuring rod 1031 is provided on the dial indicator, and the measuring rod 1031 is fixedly connected to the linkage rod 102. When the roadbed sinks, the linkage rod 102 drives the measuring rod 1031 to descend, and the sliding of the measuring rod 1031 can make the sliding value displayed on the dial indicator, which is the distance of the linkage rod 102, that is, the foundation settlement depth. Among them, the roadbed observation point is an observation point fixed on the ground surface, which does not settle with the settlement of the roadbed.

[0035] In the prior art, the measurement of roadbed settlement is performed by converting the movement of multiple objects driven by the roadbed settlement to obtain the settlement measurement result, and the measurement accuracy is poor. In the roadbed measurement device provided in this embodiment, when the roadbed settles, the linkage rod 102 is driven to move, and the measuring instrument 103 can directly obtain the settlement result according to the movement distance of the linkage rod 102, which only involves the movement conversion of one object, the linkage rod 102, and the settlement measurement accuracy is high.

[0036] Further preferably, one end of the linkage rod 102 can be connected to the bottom plate 101 through the casing 104, and the other end can be connected to the measuring rod 1031 through the settlement observation mark tube 105. For the monitoring of the settlement of the roadbed at different depths, the bottom plate 101 of the measuring component 1 needs to be buried to different depths. In this embodiment, linkage rods 102 of different lengths can be connected through pipe sleeves or through casings 104 of different lengths or other adjustment methods to adapt to the measurement of roadbeds at different depths. The role of the settlement observation mark tube is to facilitate installation.

[0037] In order to increase the durability of the monitoring device and effectively prevent errors in monitoring accuracy caused by environmental factors, in this embodiment, the linkage rod 102, the sleeve 104, the bottom plate 101, and the settlement observation marker tube 105 are set to be made of aluminum alloy.

[0038] As a preferred embodiment of the present invention, the fixing component 3 includes a connecting rod 301 fixedly connected to the roadbed observation point; the number of the connecting rods 301 is 2, which are symmetrically fixed on the measuring instrument 103.

[0039] In order to further improve the measurement accuracy, the measuring instrument 103 micrometer needs to be stably fixed to prevent environmental factors, such as wind, from causing deviations in monitoring accuracy. In this embodiment, the number of connecting rods 301 is set to 2, and the connecting rods 301 are symmetrically arranged on the measuring instrument 103, which helps to better fix the measuring instrument 103.

[0040] More preferably, the fixing component 3 is disposed in the protection box 302 .

[0041] In order to better fix the measuring instrument 103 and prevent the monitoring accuracy from decreasing due to environmental factors, the fixing component 3 is also disposed in the protection box 302. Since the connecting rod 301 of the fixing component 3 is connected to the measuring instrument 103, the measuring instrument 103 is also in the protection box 302.

[0042] Specifically, the fixing component 3 also includes a first fixing plate 303, a connecting plate 304, and a second fixing plate 305 connected in sequence. The first fixing plate 303 is fixedly connected to the roadbed observation point, and the second fixing plate 305 is connected to the connecting rod 301. Through the arrangement of the first fixing plate 303, the connecting plate 304, and the second fixing plate 305, the measuring component can be adapted to the position fixation of different scenes. For example, when there is a protruding foreign object between the measuring component and the roadbed observation point, the length of the connecting plate 304 can be lengthened so that the foreign object is in the space formed by the connecting rod 301, the second fixing plate 305, and the connecting plate 304, so as to achieve the fixing of the measuring component; for another example, when the roadbed observation point is directly to the right of the measuring component, and there is a high protruding foreign object between the measuring component and the roadbed observation point, the second fixing plate 305 can be drilled to allow the protrusion to pass through the second fixing plate 305, avoiding the influence of the protrusion, so as to achieve the fixing of the measuring component.

[0043] As a preferred embodiment of the present invention, the device provided in the present invention further includes an observation component 4 for observing the measurement results. The observation component 4 includes a level 401, which is connected to the measuring instrument 103 and is on the same horizontal line. For example, the level 401 and the measuring instrument 103 are connected to each other through the two ends of the connecting tube 403, and the level 401 and the measuring instrument 103 are on the same horizontal line.

[0044] Most of the time, the data displayed by the measuring instrument 103 is small, and it is easy to misread the display result of the measuring instrument 103 directly, which leads to measurement errors. Therefore, in order to improve the measurement accuracy, the device provided in this embodiment also includes an observation component 4 for observing the measurement result, and the value on the dial indicator of the measuring instrument 103 is observed through the level 401, and the horizontality is judged to determine the accuracy of the value.

[0045] Further preferably, the observation component 4 also includes a support frame 402, which is placed on the ground surface (the ground surface does not settle with the roadbed) and is used to support the level 401. In this embodiment, the support frame 402 is a tripod, which can improve the support stability and improve the measurement accuracy. At the same time, during installation, different heights of the support frame 402 can be used to adjust the height of the level 401 so that it is horizontally connected to the measuring instrument 103.

[0046] As a preferred embodiment of the present invention, the mounting component 2 includes a base 201, a support plate 202 fixedly connected to the base 201, a threaded sleeve 205, a motor 203, and a drill bit 204; a slide groove 2021 is provided on the support plate 202, and the threaded sleeve 205 is connected to the slide groove 2021; the threaded sleeve 205 is connected to the motor 203, and the other end of the motor 203 is connected to the drill bit 204. The base 201 includes a threaded rod 2011 and a rotating rod 2012 provided on the threaded rod 2011. The rotating rod 2012 in the present embodiment is a cross rotating rod 2012. The threaded rod 2011 is threadedly connected to the threaded sleeve 205. Since the roadbed settlement monitoring device is buried in the roadbed, a corresponding mounting component 2 needs to be provided.

[0047] The working principle of the device provided in this embodiment includes the installation principle and the roadbed settlement monitoring principle:

[0048] (1) Installation principle

[0049] The staff starts the motor 203, and the motor 203 drives the drill bit 204 to rotate, and drives the threaded sleeve plate 205 to slide downward on the slide groove 2021 to drill holes in the highway. When the hole is drilled to a certain position, the motor 203 is stopped, and then the rotating rod 2012 is rotated in the opposite direction, and the threaded sleeve 205 is driven to move upward through the threaded rod 2011. At this time, the staff removes the drill bit 204, and buries the settlement observation marking tube 105, the linkage rod 102, the casing 104 and the base plate 101 in the drilled hole, so that the upper end of the settlement observation marking tube 105 is exposed to the ground, and then the linkage rod 102, the casing 104 and the base plate 101 are buried. At this time, the staff vertically sets the measuring instrument 103 and the measuring rod 1031 on the settlement observation marking tube, and horizontally places the level 401 through the support frame 402, and horizontally places the level 401 and the measuring instrument 103, and then respectively connects the two ends of the connecting pipe 403 to the level 401 and the measuring instrument 103.

[0050] (2) Principle of roadbed settlement monitoring

[0051] When the roadbed sinks or rises, it will drive the measuring rod 1031 to slide, so that the measuring instrument 103, such as the dial indicator, can display the sliding value. Then, the value on the dial indicator is observed through the level 401, and the horizontality is judged to determine the accuracy of the value.

[0052] Compared with the prior art, the beneficial effects of this embodiment include at least the following aspects:

[0053] (1) In the prior art, the measurement of roadbed settlement is performed by converting the movement of multiple objects driven by the roadbed settlement to obtain the settlement measurement result, and the measurement accuracy is poor. In the roadbed measurement device provided in this embodiment, when the roadbed settles, the linkage rod is driven to move, and the measuring instrument can directly obtain the settlement result according to the movement distance of the linkage rod. It only involves the movement conversion of one object, the linkage rod, and the settlement measurement accuracy is high. At the same time, this embodiment can simplify the monitoring operation and increase the monitoring efficiency.

[0054] (2) Furthermore, in order to further improve the accuracy of roadbed settlement monitoring, this embodiment uses a level to observe the value on the dial indicator and judge the horizontality to determine the accuracy of the value.

[0055] (3) Furthermore, this embodiment adds a fixing component, and symmetrically sets the fixed measuring instrument through double connecting rods; and connects the measuring instrument to the roadbed settlement monitoring point through the fixing member (first fixing plate, connecting plate, second fixing plate), and further sets the fixing component in the protective box; at the same time, this embodiment also sets the linkage rod, casing, bottom plate, and settlement observation mark tube to be made of aluminum alloy. The above settings can effectively prevent the monitoring accuracy from decreasing due to environmental factors, and further improve the roadbed settlement monitoring accuracy.
