[0002] An excavation pit is a pit dug at the foundation design location according to the base elevation and foundation plane dimensions. Before excavation, the excavation plan should be determined based on geological and hydrological data and the conditions of nearby buildings, and waterproofing and drainage work should be done. Excavation pit deformation monitoring is the monitoring of the support structure using precision instruments and equipment during the excavation process.

[0003] Existing total stations require a specialized support frame on a trolley for monitoring foundation pits. The total station is then mounted on the frame and used to monitor the pit. However, the existing structure cannot effectively level the total station, thus affecting measurement accuracy. Utility Model Content

[0004] This application provides a bedrock deformation monitoring device, which to some extent improves the technical problem in related technologies where the total station cannot be properly leveled, thus affecting the accuracy of measurements.

[0005] This application provides a bedrock deformation monitoring device, including:

[0006] A drive vehicle and a support unit, wherein the support unit is mounted on the drive vehicle;

[0007] The leveling unit includes a clamping component, a movable sleeve, and a gravity vertical rod support. The clamping component is disposed in the support unit, and part of the gravity vertical rod support is movably disposed in the movable sleeve. The clamping component is fixedly inserted into the movable sleeve and can clamp against or separate from the gravity vertical rod support.

[0008] The total station is mounted on top of the gravity plumb bob support;

[0009] When the clamping component is separated from the gravity plumb bob support, the gravity plumb bob support can automatically level itself under its own weight to calibrate the total station horizontally.

[0010] In some embodiments, the gravity vertical support includes a rod and a movable member, a horizontal member, and a mounting plate disposed on the rod. The mounting plate is located at the top of the rod, the horizontal member is located at the bottom of the rod, and the movable member is located between the mounting plate and the horizontal member. At least a portion of the movable member is movably disposed within the movable sleeve.

[0011] In some embodiments, the clamping assembly includes a piston and a plurality of pneumatic clamping members. The piston is connected to the support unit, and the plurality of pneumatic clamping members are spaced apart on the piston. One end of each pneumatic clamping member is fixedly connected to the piston and the other end is fixedly inserted into the movable sleeve. When the pressure inside the piston changes, the pneumatic clamping member can clamp against or separate from the gravity vertical rod support.

[0012] In some embodiments, the piston assembly includes a piston cylinder seat, a piston pull plate, and a guide member. The piston pull plate is movably disposed within the piston cylinder seat to divide the piston cylinder seat into an upper chamber and a lower chamber. The guide member is movably assembled to the support unit and passes through the piston cylinder seat to connect with the piston pull plate. A plurality of pneumatic pressing members communicate with the upper chamber or the lower chamber.

[0013] In some embodiments, the leveling unit further includes a dust removal assembly, which includes a connected dust removal pipe and multiple vent pipes. The dust removal pipe is wound around the movable sleeve and has air jet holes facing into the movable sleeve. The multiple vent pipes are spaced apart from the dust removal pipe and are connected to the lower chamber or the upper chamber.

[0014] In some embodiments, the dust removal pipe has two pipes, which are staggered. The dust removal assembly includes multiple connecting pipes that correspond one-to-one with the ventilation pipe. The multiple connecting pipes connect the two dust removal pipes, and the ventilation pipe is connected to the corresponding connecting pipe.

[0015] In some embodiments, a portion of the gravity plumb line extends beyond the top and bottom of the movable sleeve, and two dust removal pipes are respectively disposed at the top and bottom of the movable sleeve.

[0016] In some embodiments, the pneumatic pressing component includes an installation pipe, an elastic element, and a pressing element. One end of the installation pipe is fixedly connected to the piston component, and the other end is fixedly inserted into the movable sleeve. The pressing element is disposed inside the end of the installation pipe near the movable sleeve. The elastic element connects the inner wall of the installation pipe and the pressing element. At least a portion of the pressing element can be exposed outside the installation pipe. The elastic element can contract or recover when the pressure inside the piston component changes, so as to drive the pressing element to press against or separate from the gravity vertical rod support.

[0017] In some embodiments, the installation conduit includes a connected pipe body and a pressure cylinder, the pipe body being fixedly connected to the piston member, the pressure cylinder being fixedly inserted into the movable sleeve, and the elastic member and the clamping member being disposed inside the pressure cylinder.

[0019] The beneficial effects of this application are as follows:

[0020] In the bedrock deformation monitoring device provided in this application, since the gravity plumb bob can automatically level itself under its own weight when the clamping component is separated from the gravity plumb bob, the total station can be leveled by separating the clamping component from the gravity plumb bob, thus improving the measurement accuracy.

[0034] Please see Figure 1 This application provides a bedrock deformation monitoring device 10, including a drive vehicle 100, a support unit 200, a leveling unit 300, and a total station 400. The support unit 200 is mounted on the drive vehicle 100; the leveling unit 300 includes a clamping component 310, a movable sleeve 320, and a gravity plumb bob support 330. The clamping component 310 is mounted on the support unit 200, and a portion of the gravity plumb bob support 330 is movably mounted within the movable sleeve 320. The clamping component 310 is fixedly inserted into the movable sleeve 320 and can clamp against or separate from the gravity plumb bob support 330; the total station 400 is mounted on top of the gravity plumb bob support 330.

[0035] When the clamping component 310 is separated from the gravity plumb rod support 330, the gravity plumb rod support 330 can automatically level itself under its own weight to calibrate the total station 400 level.

[0036] The drive vehicle 100 serves as the basic structure for the bedrock deformation monitoring device 10, providing installation and protection for other components of the device. When the total station 400 needs to be moved, the drive vehicle 100 can be pushed. The support unit 200 is fixedly mounted on the drive vehicle 100, providing support for the total station 400 and other components.

[0037] The clamping component 310 is fixedly connected to the support unit 200, and since the clamping component 310 is fixedly inserted into the movable sleeve 320, i.e., the movable sleeve 320 is fixedly connected to the clamping component 310, the movable sleeve 320 is thus fixedly installed. Because part of the gravity plumb bob support 330 is movably installed within the movable sleeve 320, the total station 400 is installed on top of the gravity plumb bob support 330, thereby achieving the installation of the total station 400.

[0038] The clamping component 310 can clamp against or separate from the gravity vertical rod support 330. That is, when the clamping component 310 clamps against the gravity vertical rod support 330, the gravity vertical rod support 330 is fixed inside the movable sleeve 320, and when the clamping component 310 separates from the gravity vertical rod support 330, the gravity vertical rod support 330 can move inside the movable sleeve 320.

[0039] Under normal circumstances, the clamping component 310 is clamped against the gravity plumb rod support 330. However, when monitoring bedrock deformation, the clamping component 310 is separated from the gravity plumb rod support 330, allowing the gravity plumb rod support 330 to automatically level itself under its own weight. Since the total station 400 is installed on top of the gravity plumb rod support 330, the level of the total station 400 is calibrated, improving measurement accuracy. Once the total station 400 is level and stable, the clamping component 310 is then clamped against the gravity plumb rod support 330.

[0040] Please see Figures 1-3 In some embodiments, the gravity vertical support 330 includes a rod 331 and a movable member 332, a horizontal member 333, and a mounting plate 334 disposed on the rod 331. The mounting plate 334 is located at the top of the rod 331, the horizontal member 333 is located at the bottom of the rod 331, and the movable member 332 is located between the mounting plate 334 and the horizontal member 333. At least part of the movable member 332 is movably disposed within the movable sleeve 320.

[0041] Since the horizontal component 333 is located at the bottom of the rod 331, the gravity support 330 can be automatically leveled by the weight of the horizontal component 333 itself. The mounting plate 334 is used to mount the total station 400. When the horizontal component 333 achieves automatic leveling of the gravity support 330 under its own weight, the movable component 332 moves within the movable sleeve 320.

[0042] Specifically, both the movable component 332 and the horizontal component 333 can be spherical structures. Since the automatic leveling of the gravity vertical support 330 is achieved through the self-weight of the horizontal component 333, the mass and volume of the horizontal component 333 can be greater than the mass and volume of the movable component 332. The movable sleeve 320 can be a ball sleeve, meaning that the movable fit between the movable component 332 and the movable sleeve 320 is a rotational connection between a ball head and a ball sleeve.

[0043] Please see Figure 3 In some embodiments, the clamping assembly 310 includes a piston 311 and a plurality of pneumatic clamping members 312. The piston 311 is connected to the support unit 200, and the plurality of pneumatic clamping members 312 are spaced apart on the piston 311. One end of the pneumatic clamping member 312 is fixedly connected to the piston 311, and the other end is fixedly inserted through the movable sleeve 320. When the pressure inside the piston 311 changes, the pneumatic clamping member 312 can clamp against or separate from the gravity vertical rod support 330.

[0044] Since one end of the pneumatic pressing member 312 is fixedly connected to the piston member 311, the pressure change within the piston member 311 can affect the gas flow within the pneumatic pressing member 312. By changing the pressure change within the piston member 311, the pneumatic pressing member 312 can be pressed against or separated from the gravity vertical support 330. Multiple pneumatic pressing members 312 together press against the gravity vertical support 330, thus fixing the gravity vertical support 330 within the movable sleeve 320. Of course, the multiple pneumatic pressing members 312 are arranged circumferentially around the gravity vertical support 330.

[0045] In some embodiments, the piston component 311 includes a piston cylinder seat 3111, a piston pull plate 3112, and a guide member 3113. The piston pull plate 3112 is movably disposed within the piston cylinder seat 3111 to divide the piston cylinder seat 3111 into an upper chamber and a lower chamber. The guide member 3113 is movably assembled to the support unit 200 and passes through the piston cylinder seat 3111 to connect with the piston pull plate 3112. A plurality of pneumatic pressing members 312 communicate with the upper chamber or the lower chamber.

[0046] The piston pull plate 3112 can move up and down within the piston cylinder seat 3111. Since the guide member 3113 is movably mounted on the support unit 200 and passes through the piston cylinder seat 3111 to connect with the piston pull plate 3112, the guide member 3113 also moves up and down along the support unit 200 while the piston pull plate 3112 moves up and down, thus guiding the movement of the piston pull plate 3112. It is understood that the pressure in both the upper and lower chambers changes during the up and down movement of the piston pull plate 3112. Because multiple pneumatic pressing members 312 are connected to the upper or lower chamber, the pneumatic pressing members 312 can press against or separate from the gravity vertical support 330.

[0047] Please see Figure 3 and Figure 4 In some embodiments, the leveling unit 300 further includes a dust removal assembly 340, which includes a connected dust removal pipe 341 and multiple ventilation pipes 342. The dust removal pipe 341 is wound around the movable sleeve 320 and has air jet holes 344 facing into the movable sleeve 320. The multiple ventilation pipes 342 are spaced apart from the dust removal pipe 341 and are connected to the lower chamber or the upper chamber.

[0048] Understandably, when the piston plate 3112 moves downward, the volume of the upper chamber increases, the gas expands, and the pressure decreases, creating a negative pressure (lower than the external atmospheric pressure). Conversely, the volume of the lower chamber decreases, the gas is compressed, and the pressure increases, creating a positive pressure (higher than the external atmospheric pressure). The opposite occurs when the piston plate 3112 moves upward. Therefore, depending on the direction of movement of the piston plate 3112, both the upper and lower chambers may form positive pressure. The vent pipe 342 connects to either the lower or upper chamber that forms positive pressure, allowing air to be drawn from either chamber. The gas is then ejected through the jet hole 344, providing dust protection at the rotating connection between the movable sleeve 320 and the gravity plumb rod support 330. This ensures the smoothness of the rotation adjustment of the gravity plumb rod support 330, thereby guaranteeing the leveling effect.

[0049] Specifically, there are two dust removal pipes 341, which are staggered. The dust removal assembly 340 includes multiple connecting pipes 343 that correspond one-to-one with the ventilation pipes 342. The multiple connecting pipes 343 connect the two dust removal pipes 341, and the ventilation pipes 342 are connected to their corresponding connecting pipes 343. A portion of the gravity plumb line extends out from the top and bottom of the movable sleeve 320, and the two dust removal pipes 341 are respectively located at the top and bottom of the movable sleeve 320.

[0050] Please see Figure 3 and Figure 5 In some embodiments, the pneumatic pressing member 312 includes an installation pipe 3121, an elastic member 3122, and a pressing member 3123. One end of the installation pipe 3121 is fixedly connected to the piston member 311, and the other end is fixedly inserted into the movable sleeve 320. The pressing member 3123 is disposed in the end of the installation pipe 3121 near the movable sleeve 320. The elastic member 3122 connects the inner wall of the installation pipe 3121 and the pressing member 3123. At least part of the pressing member 3123 can be exposed outside the installation pipe 3121. The elastic member 3122 can contract or recover when the pressure inside the piston member 311 changes, so as to drive the pressing member 3123 to press against or separate from the gravity vertical rod support 330.

[0051] The elastic element 3122 can extend and retract along the airflow direction in the installation pipe 3121. When a negative pressure is formed in the piston 311, the elastic element 3122 will contract, thereby causing the clamping element 3123 to retract completely into the installation pipe 3121 to separate from the gravity vertical rod support 330. When the pressure in the piston 311 returns to normal, the elastic element 3122 will return, thereby causing at least part of the clamping element 3123 to be exposed in the installation pipe 3121 to clamp against the gravity vertical rod support 330.

[0052] Specifically, the clamping element 3123 can be made of a flexible material such as rubber to enhance the clamping effect without damaging the outer wall of the gravity support 330, and the elastic element 3122 can be a spring.

[0053] As described above, both the upper and lower chambers can potentially experience negative pressure. Therefore, it is sufficient to connect the installation pipe 3121 to the upper or lower chamber where negative pressure is generated. Specifically, the installation pipe 3121 is connected to the upper chamber, and the vent pipe 342 is connected to the lower chamber. When leveling the total station 400, the piston plate 3112 is pulled down, causing negative pressure to form in the upper chamber and positive pressure in the lower chamber. This achieves the leveling of the gravity plumb bob support 330 and provides dust protection at the rotating connection between the movable sleeve 320 and the gravity plumb bob support 330.

[0054] Specifically, the cross-sections of both the piston cylinder seat 3111 and the piston pull plate 3112 can be isosceles triangles. There are three installation pipes 3121, and the three installation pipes 3121 are connected to the three corners of the piston cylinder seat 3111 respectively, so that the installation pipes 3121 are connected to the center of gravity of the upper chamber, thereby achieving stable gas flow.

[0055] In some embodiments, the installation pipe 3121 includes a connected pipe body 31211 and a pressure cylinder 31212. The pipe body 31211 is fixedly connected to the piston member 311, and the pressure cylinder 31212 is fixedly inserted into the movable sleeve 320. The elastic member 3122 and the clamping member 3123 are disposed inside the pressure cylinder 31212.

[0056] To facilitate the installation of the elastic element 3122 and the clamping element 3123, the elastic element 3122 and the clamping element 3123 are disposed inside the pressure cylinder 31212. The pressure cylinder 31212 has two side walls that are arranged opposite to each other along the airflow direction. The elastic element 3122 is connected to one of the side walls, while the other side wall limits the clamping element 3123.

[0057] Please see Figure 6 In some embodiments, the support unit 200 includes a lifting assembly 210, a straightening plate 220, and two telescopic assemblies 230. The abutting assembly 310 and the straightening plate 220 are disposed at the movable end of the lifting assembly 210, and the two telescopic assemblies 230 are disposed on both sides of the straightening plate 220. The telescopic end of the telescopic assembly 230 is hinged to the movable end of the lifting assembly 210, and the fixed end of the telescopic assembly 230 is hinged to the drive vehicle 100.

[0058] Since the clamping component 310 is located at the movable end of the lifting component 210, and the total station 400 is also located on the lifting component 210, the height of the total station 400 can be adjusted by lifting the lifting component 210 after the bedrock deformation monitoring device 10 is moved to the working location. The telescopic component 230 can extend and retract. Since the straightening plate 220 is located at the movable end of the lifting component 210, and the two telescopic components 230 are located on both sides of the straightening plate 220, the telescopic end of the telescopic component 230 is hinged to the movable end of the lifting component 210, and the fixed end of the telescopic component 230 is hinged to the drive vehicle 100. Therefore, while the lifting component 210 is rising and falling, the telescopic component 230 also extends and retracts accordingly, thereby effectively providing stable support for the lifting component 210 and ensuring the stability of the lifting component 210.

[0059] Specifically, both the lifting assembly 210 and the telescopic assembly 230 can be in the form of telescopic sleeves and telescopic rods to achieve lifting or telescopic movement, which will not be elaborated further here.

[0060] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0061] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
