Description

Technical Field

[0001] This invention relates to the field of measurement equipment technology, and specifically to a land planning terrain flatness measurement device. Background Technology

[0002] Land planning refers to the strategic layout of land development, utilization, management, and protection within a specific region, based on the needs of sustainable socio-economic development and natural conditions. Before conducting land planning, data measurements are taken of the relevant area to obtain accurate information and provide data support for subsequent land planning.

[0003] For measuring land flatness, existing technologies often use triangulation rangefinders as the measuring equipment. However, triangulation rangefinders rely on manual labor, and workers need to carry the equipment to different measuring points, which is time-consuming and labor-intensive. Therefore, existing technologies have also provided automated measuring vehicles, which are placed in relevant areas and automatically complete the measurement of relevant data.

[0004] The drawback of existing automated surveying vehicles is that while their wheeled construction offers advantages in terms of economy and lifespan, their poor maneuverability makes them unsuitable for surveying soft terrain. Summary of the Invention

[0005] The technical problem to be solved by the present invention is that existing automated surveying vehicles have poor passability in soft areas. The purpose is to provide a land planning terrain flatness measurement device to solve the above-mentioned problem.

[0006] This invention is achieved through the following technical solution:

[0007] A land planning terrain flatness measuring device includes a measuring module and a vehicle body;

[0008] The measurement module is installed on the vehicle body and is used to measure flatness;

[0009] The vehicle body has two opposite sides, and each side is equipped with a wheel. A retractable track module is provided between the vehicle body and the wheel, so that the track module can be detachably connected to the wheel, so that the vehicle body has both wheeled and tracked modes.

[0010] In one possible design, the traveling wheel includes a support rod and a wheel body;

[0011] One end of the support rod is connected to the vehicle body through the first hinge seat, and the other end of the support rod is tilted downward and connected to the wheel body through the second hinge seat, so that the vehicle body is suspended in the air;

[0012] The support rod has an inclined moving position and a switching position that rotates to a horizontal position around the first hinge seat. Accordingly, when the support rod is in the switching position, the wheel is suspended in the air, and the track module is connected to or disconnected from the wheel by telescopic connection.

[0013] In one possible design, the vehicle body is equipped with a lifting frame, which lifts the vehicle body so that the wheels are suspended in the air when the vehicle body switches between wheeled and tracked modes.

[0014] In one possible design, the lifting frame includes a detachable frame located at the rear of the vehicle body. The detachable frame includes a base and a telescopic rod. The base is detachably connected to the vehicle body, and a connecting rope is provided between the base and the vehicle body. The telescopic rod passes through the base and is used to lift the vehicle body.

[0015] In one possible design, the track module includes a skateboard, a sleeve, a control cylinder, and the track body;

[0016] The sliding plate is mounted on the vehicle body. The sliding plate has a working surface facing outwards. Correspondingly, the sliding plate is connected to the sleeve and the control cylinder through the working surface.

[0017] A control lever is connected to the side of the sleeve, and the sleeve is connected to the slide plate through the control lever. The inner circumferential surface of the sleeve is provided with a locking strip for connecting the wheel body, and the wheel body is provided with a slot adapted to the locking strip. Accordingly, when the track module is connected to the wheel body, the sleeve is sleeved on the wheel body, and the locking strip is inserted into the slot.

[0018] The control cylinder is slidably mounted on the slide plate and coaxially mounted with the sleeve, and the control cylinder is inserted into the sleeve; accordingly, when the slide plate slides along the vehicle body, the control cylinder is sleeved on the support rod and drives the support rod to rotate around the first hinge seat, so that the wheel body is suspended in the air;

[0019] The sleeve is provided in two spaced apart, and the track body is sleeved on the two sleeves. Correspondingly, one of the two sleeves is constructed as a drive wheel and the other is constructed as a guide wheel.

[0020] In one possible design, the skateboard also has several intermediate wheels, which are located between two sleeves and spaced apart. Accordingly, the intermediate wheels are divided into drag wheels, load-bearing wheels and special function wheels.

[0021] In one possible design, the control lever is constructed as a sliding rod to drive the sleeve toward or away from the slide plate, and the track body moves synchronously with the sleeve accordingly.

[0022] In one possible design, the sleeve includes a collar and a resilient connector;

[0023] Two collars are provided and arranged opposite each other, and the two collars are connected by an elastic connector; of the two collars, one is constructed as the near collar adjacent to the skateboard, and the other is constructed as the far collar away from the skateboard.

[0024] One end of the control rod is connected to the slide plate, and the other end passes through the near ring and connects to the far ring; correspondingly, when the control rod is constructed as a sliding rod, the sleeve has a cylindrical station with two opposing and spaced collars and a folded station with the two collars touching, through the sliding of the control rod.

[0025] In one possible design, the card strip includes two first bases respectively disposed on the collar and an intermediate piece for connecting the two first bases;

[0026] The track body includes two second bases respectively disposed on collars and a running belt for connecting the two second bases, and the running belt is foldable;

[0027] Accordingly, the first base is disposed on the inner circumferential surface of the collar, and the second base is disposed on the outer circumferential surface of the collar.

[0028] In one possible design, the vehicle body is equipped with an adjustment module for adjusting the tilt angle of the measurement module. The adjustment module includes a base ring, a ball, a base rod, and an adjustment rod.

[0029] The base ring is set inside the vehicle body and placed horizontally. The base ring is provided with a ring track, and the rolling ball is slidably set in the ring track.

[0030] The base rod is rotatably mounted inside the vehicle body and located on the axis of the base ring. The end of the base rod is provided with a cage for connecting the rolling ball. Accordingly, the rolling ball rolls along the annular track to drive the base rod to rotate.

[0031] There are two adjusting rods located at both ends of the base rod. Correspondingly, the adjusting rods have a telescopic function to raise the measuring module.

[0032] The base ring has a column on its bottom surface, and the base ring is connected to the vehicle body through the column. The base ring is equipped with a lifting clamping plate, which is used to fix the position of the rolling ball.

[0033] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0034] The land planning terrain flatness measuring device has wheeled and tracked modes, and can switch between different modes according to different land conditions to ensure that the land planning terrain flatness measuring device can adapt to different terrains and has good passability.

[0052] Example:

[0053] like Figures 1-10 As shown, a land planning terrain flatness measuring device includes a measuring module 1 and a vehicle body 2;

[0054] Measurement module 1 is installed on vehicle body 2 and is used for flatness measurement;

[0055] The vehicle body 2 has two opposite sides, and each side is provided with a traveling wheel 3. A retractable track module 4 is provided between the vehicle body 2 and the traveling wheel 3 so that the track module 4 can be detachably connected to the traveling wheel 3, so that the vehicle body 2 has a wheeled mode and a tracked mode.

[0056] To address the problems existing in the prior art, the land planning terrain flatness measuring device is equipped with a tracked module 4. The tracked module 4 is telescopic; normally, it retracts and detaches from the wheels 3, allowing the device to move via the wheels. In soft soil areas, the tracked module 4 extends and connects to the wheels 3, driving the tracked module 4 to rotate and thus move the device. Therefore, the land planning terrain flatness measuring device has both wheeled and tracked modes, switching between different modes according to different land conditions to ensure its adaptability to various terrains and good maneuverability.

[0057] For the land planning terrain flatness measuring device, the measuring module 1 can be any suitable existing module, offering a wide range of choices and good practicality. The vehicle body 2 is equipped with sensors, a battery, a driver, a controller, and other devices. The sensors are used to perceive external information, the battery powers the land planning terrain flatness measuring device, the driver provides power for the movement of the device, and the controller connects and coordinates the operation of each component to achieve automatic operation of the land planning terrain flatness measuring device.

[0058] During operation, staff place the land planning terrain flatness measuring device in the area to be measured and then activate it. The device moves to different measurement points, where it measures and collects data via measurement module 1. Depending on the accessibility of the area, the device switches between wheeled and tracked modes. After measurement, staff retrieve the device.

[0059] It is worth noting that the land planning terrain flatness measurement device is also equipped with a wireless communication module. When the land planning terrain flatness measurement device is working, it is connected to the control terminal through the wireless communication module. The staff can monitor the equipment's working information and the measured data in real time through the control terminal, which not only makes it convenient for the staff to keep track of the real-time working situation, but also makes it convenient for the staff to deal with abnormal situations in a timely manner.

[0060] In one possible implementation, the walking wheel 3 includes a support rod 301 and a wheel body 302;

[0061] One end of the support rod 301 is connected to the vehicle body 2 through the first hinge seat, and the other end of the support rod 301 is tilted downward and connected to the wheel body 302 through the second hinge seat, so that the vehicle body 2 is suspended in the air;

[0062] The support rod 301 has an inclined moving position and a switching position that rotates to a horizontal position around the first hinge seat. Accordingly, when the support rod 301 is in the switching position, the wheel body 302 is suspended in the air, and the track module 4 is connected to or disconnected from the wheel body 302 by telescopic connection.

[0063] Based on the above design, the inclined support rod 301 serves a connecting function and also raises the vehicle body 2, ensuring that the chassis height of the land planning terrain flatness measuring device meets the design requirements and also helps protect the vehicle body 2. Conversely, when the track module 4 is connected to the traveling wheel 3, that is, when the track module 4 is fitted onto the wheel body 302, the rotation of the support rod 301 raises the wheel body 302, making the wheel body 302 aligned with the track module 4, thus improving the accuracy of the connection between the track module 4 and the wheel body 302.

[0064] Accordingly, the first hinge seat allows the support rod 301 to rotate relative to the vehicle body 2 through the hinge. Similarly, after the support rod 301 rotates, the wheel 302 rotates relative to the second hinge seat by gravity, so that the wheel 302 and the track module 4 remain parallel to each other, and the wheel 302 and the track module 4 are aligned.

[0065] In one possible implementation, the vehicle body 2 is provided with a lifting frame, which lifts the vehicle body 2 when the vehicle body 2 switches between wheeled and tracked modes, so that the wheels 302 are suspended in the air.

[0066] Based on the above design, when the support rod 301 rotates, without additional support, the vehicle body 2 will descend instead of the wheel body 302 rising in the land planning terrain flatness measuring device. Therefore, an additional support is provided by setting up a lifting frame to ensure that the height of the vehicle body 2 remains stable. Thus, when the support rod 301 rotates, the vehicle body 2 remains relatively stationary, and the wheel body 302 rises and is suspended in the air, so as to facilitate the subsequent disassembly and assembly of the track module 4 and the wheel body 302.

[0067] Optionally, the lifting frame includes a detachable frame 5 located at the rear of the vehicle body 2. The detachable frame 5 includes a base 501 and a telescopic rod 502. The base 501 is detachably connected to the vehicle body 2, and a connecting rope 6 is provided between the base 501 and the vehicle body 2. The telescopic rod 502 passes through the base 501 and is used to lift the vehicle body 2.

[0068] Based on the above design, although the tracked module 4 enables the land planning and terrain flatness measuring device to have a tracked mode, improving its mobility, unexpected situations may still occur in some special areas, such as silt-filled areas or areas with sinkholes. In such cases, workers can pull the connecting rope 6 to retrieve the land planning and terrain flatness measuring device, preventing workers from entering these special areas and improving worker safety.

[0069] It is easy to understand that before the land planning terrain flatness measuring device enters a special area, the detachable frame 5 is removed from the vehicle body 2 and the telescopic rod 502 is inserted into the ground. The land planning terrain flatness measuring device can move and measure within the length range of the connecting rope 6.

[0070] Furthermore, the base 501 is connected to the connecting rope 6 via a winding machine. On the one hand, the winding machine controls the length of the connecting rope 6 to prevent it from getting tangled and hindering the movement of the land planning terrain flatness measuring device. On the other hand, the winding machine pulls the land planning terrain flatness measuring device to move, enabling the land planning terrain flatness measuring device to move on its own and reducing the workload of the staff.

[0071] In one possible implementation, the track module 4 includes a sliding plate 401, a sleeve 402, a control cylinder 403, and a track body 404.

[0072] The slide plate 401 is slidably mounted on the vehicle body 2. The slide plate 401 has a working surface facing outward. Correspondingly, the slide plate 401 is connected to the sleeve 402 and the control cylinder 403 through the working surface.

[0073] A control rod 405 is connected to the side of the sleeve 402. Correspondingly, the sleeve 402 is connected to the slide plate 401 through the control rod 405. The inner circumferential surface of the sleeve 402 is provided with a retaining strip 406 for connecting the wheel body 302. The wheel body 302 is provided with a groove adapted to the retaining strip 406. Correspondingly, when the track module 4 is connected to the wheel body 302, the sleeve 402 is sleeved on the wheel body 302 and the retaining strip 406 is inserted into the groove.

[0074] The control cylinder 403 is slidably mounted on the slide plate 401 and coaxially mounted with the sleeve 402, and the control cylinder 403 is inserted into the sleeve 402; accordingly, when the slide plate 401 slides along the vehicle body 2, the control cylinder 403 is sleeved on the support rod 301 and drives the support rod 301 to rotate around the first hinge seat, so that the wheel body 302 is suspended in the air.

[0075] Two sleeves 402 are provided and spaced apart. The track body 404 is sleeved on the two sleeves 402. Correspondingly, one of the two sleeves 402 is constructed as a drive wheel and the other is constructed as a guide wheel.

[0076] Based on the above design, when the land planning terrain flatness measuring device switches from wheeled mode to tracked mode, the lifting frame moves down and supports the vehicle body 2, the sliding plate 401 slides outward, the control cylinder 403 is fitted onto the support rod 301 and drives the support rod 301 to rotate, and the wheel body 302 is suspended and aligned with the sleeve 402. The sliding plate 401 continues to move outward until the sleeve 402 is fitted onto the wheel body 302, at which point the retaining strip 406 on the sleeve 402 is inserted into the retaining groove of the wheel body 302. When the wheel body 302 rotates, the driving force is transmitted to the sleeve 402 through the retaining strip 406 groove, causing the track module 4 to rotate. The control cylinder 403 resets, causing the wheel body 302, sleeve 402, and track body 404 to rotate downward under the action of gravity until the support rod 301 returns to its tilt. The lifting frame is reset, the support rod 301 rotates and resets, so that the track body 404 touches the ground, and the land planning terrain flatness measuring device is in track mode and moves in the area to be measured.

[0077] Accordingly, the connection between the control lever 405 and the slide plate 401 is a rotatable connection to ensure that the control lever 405, the sleeve 402, and the track body 404 can rotate relative to the slide plate 401. For example, the rotatable connection can take the form of: the control lever 405 is fitted with a sleeve, and the sleeve is rotatably connected to the slide plate 401; or, the rotatable connection can be any suitable existing connection method.

[0078] Conversely, when the land planning terrain flatness measuring device switches from tracked mode to wheeled mode, the lifting frame moves down and supports the vehicle body 2, the control cylinder 403 moves outward and drives the support rod 301 to rotate, causing the wheel 302, sleeve 402, track body 404 and control rod 405 to rotate and suspend in the air. The sliding plate 401 then moves back into the vehicle body 2 and resets, and the sleeve 402 and track body 404 disengage from the wheel 302. The control cylinder 403 then resets, and the support rod 301 rotates and resets, causing the wheel 302 to touch the ground. The land planning terrain flatness measuring device is then in wheeled mode and moves in the area to be measured.

[0079] Optionally, the skateboard 401 is also provided with several intermediate wheels 407, which are located between the two sleeves 402 and spaced apart. Accordingly, the intermediate wheels 407 are divided into towing wheels, load-bearing wheels, and special function wheels. Based on the above design, the intermediate wheels 407 are used to improve the walking performance of the track module 4, ensuring that the land planning terrain flatness measuring device has good passability in track mode.

[0080] As is easily understood, the intermediate wheel 407 is connected to the slide plate 401 via a rod and moves with the slide plate 401. Regarding the types of intermediate wheels 407, depending on actual operational needs, selections and combinations can be made between towing wheels, load-bearing wheels, and special-function wheels, resulting in various implementation schemes to adapt to different environments.

[0081] Considering that the vehicle body 2 is equipped with track module 4 and wheel body 302, and that the extension and retraction of track module 4 requires a certain amount of space, when the volume of vehicle body 2 is small, in order to avoid the use of track module 4 occupying the space of internal components of vehicle body 2, the structure of track module 4 is improved. Specifically, in one possible implementation, control rod 405 is constructed as a sliding rod to drive sleeve 402 to move closer to or away from slide plate 401. Correspondingly, track body 404 moves synchronously with sleeve 402.

[0082] Based on the above design, the control lever 405 slides relative to the slide plate 401 to reduce the distance between the slide plate 401 and the sleeve 402, thereby reducing the space occupied by the track module 4, especially when the track module 4 is separated from the wheel body 302.

[0083] Furthermore, the sleeve 402 and related components are improved to make it telescopic. When the track module 4 is separated from the wheel 302, the sleeve 402 retracts to reduce its space occupation. Specifically:

[0084] In one possible implementation, such as Figure 8 As shown, sleeve 402 includes collar 408 and elastic connector 409;

[0085] Two collars 408 are provided and arranged opposite to each other, and the two collars 408 are connected by an elastic connector 409; of the two collars 408, one is constructed as a near ring 410 adjacent to the slide plate 401, and the other is constructed as a far ring 411 away from the slide plate 401.

[0086] One end of the control lever 405 is connected to the slide plate 401, and the other end passes through the near ring 410 and is connected to the far ring 411. Correspondingly, when the control lever 405 is constructed as a sliding lever, the sleeve 402 is made to have a cylindrical station with two collars 408 facing each other and spaced apart, and a folded station with the two collars 408 touching each other.

[0087] Based on the above design, the elastic connector 409 has elastic force, which causes the two collars 408 to move away from each other, so that the sleeve 402 is in a cylindrical position. At this time, the track module 4 can be fitted onto the wheel 302. Conversely, when the track module 4 is disengaged from the wheel 302, the control lever 405 slides toward the slide plate 401. After the near ring 410 abuts against the slide plate 401, the control lever 405 continues to slide, and the far ring 411 moves accordingly and compresses the elastic connector 409, so that the distance between the near ring 410 and the far ring 411 is reduced until the sleeve 402 is in a folded position. This greatly reduces the space occupied by the track module 4.

[0088] If the track module 4 needs to connect to the wheel 302, the slide plate 401 moves outward, and the control lever 405 moves outward again. After the far ring 411 moves, the elastic connector 409 resets and increases the distance between the near ring 410 and the far ring 411 until the sleeve 402 switches to the cylindrical position.

[0089] Accordingly, the card strip 406 includes two first bases 412 respectively disposed on the collar 408 and an intermediate member 413 for connecting the two first bases 412;

[0090] The track body 404 includes two second bases 414 respectively disposed on collars 408 and a running belt 415 for connecting the two second bases 414, and the running belt 415 is foldable.

[0091] Accordingly, the first base 412 is disposed on the inner circumferential surface of the collar 408, and the second base 414 is disposed on the outer circumferential surface of the collar 408.

[0092] Therefore, since the first base 412 and the second base 414 serve as a connection, when the sleeve 402 switches positions via the elastic connector 409, the locking strip 406 and the track body 404 can move accordingly. At this time, the intermediate component 413 can be any suitable connecting component such as a rope, line, or belt. For the running track 415, any suitable protruding structure can be provided to increase friction and improve the passability of the track module 4.

[0093] Measurement module 1 has a certain self-adjusting capability to mitigate measurement errors caused by terrain undulations. However, the self-adjusting capability of measurement module 1 is limited. When the terrain undulations are too large, such as in sloping areas, or when the land planning terrain flatness measuring device is stuck in a pit, the measurement accuracy of measurement module 1 is poor. In this case, in one possible implementation, the vehicle body 2 is equipped with an adjustment module 7 for adjusting the tilt angle of measurement module 1. Based on the above design scheme, the adjustment range is increased by adjusting module 7, avoiding interference from unexpected factors on measurement module 1.

[0094] Optionally, such as Figure 9 and Figure 10 As shown, the adjustment module 7 includes a base ring 701, a ball 702, a base rod 703, and an adjustment rod 704;

[0095] The base ring 701 is installed inside the vehicle body 2 and placed horizontally. The base ring 701 is provided with an annular track 705, and the rolling ball 702 is slidably installed in the annular track 705.

[0096] The base rod 703 is rotatably mounted inside the vehicle body 2 and located on the axis of the base ring 701. The end of the base rod 703 is provided with a cage 706 for connecting the ball 702. Correspondingly, the ball 702 rolls along the annular track 705 to drive the base rod 703 to rotate.

[0097] Two adjusting rods 704 are provided and located at both ends of the base rod 703 respectively. Correspondingly, the adjusting rods 704 have a telescopic function to raise the measuring module 1.

[0098] Based on the above design, when the vehicle body 2 tilts, the base ring 701 also tilts with the vehicle body 2, and the rolling ball 702 will roll along the ring track 705 to the lowest point under the action of gravity. The base rod 703 covers the rolling ball 702 through the cage 706. When the rolling ball 702 rolls, the rolling ball 702 drives the base rod 703 to rotate, so that the base rod 703 is in an inclined state with one end down and the other end up. At this time, the adjusting rod 704 at the lower end of the base rod 703 extends outward, thereby raising the measuring module 1 to reduce the tilt degree of the measuring module 1.

[0099] To address this, gravity is used to drive the adjustment module 7 to rotate, reducing the need for additional power equipment and lowering energy consumption. Furthermore, by using gravity as a reference, the ball 702 rolls to its lowest position, and the adjustment rod 704 rotates to its lowest position, resulting in better adjustment of the adjustment rod 704.

[0100] Optionally, such as Figure 9 As shown, both ends of the base rod 703 extend onto the base ring 701, and a ball 702 is placed in the cage 706 at one end. Based on this, the center of gravity of the base rod 703 is offset from the axis of the base ring 701, so that the base rod 703 can rotate more easily with the ball 702.

[0101] Optionally, the base ring 701 has a column 707 on its bottom surface, and the base ring 701 is connected to the vehicle body 2 through the column 707. Based on this, several columns 707 are provided to ensure a stable connection between the base ring 701 and the vehicle body 2.

[0102] Optionally, the base ring 701 is equipped with a lifting clamping plate to fix the position of the rolling ball 702. Because of this, the rolling of the rolling ball 702 causes wear, increasing the frictional resistance of subsequent rolling, which in turn reduces the rotational sensitivity of the base rod 703 and the adjusting rod 704. To address this, when the measuring module 1 can self-adjust, the lifting clamping plate moves up and fixes the position of the rolling ball 702 to reduce wear. Conversely, when the adjusting module 7 is working, the lifting clamping plate moves down, allowing the rolling ball 702 to roll freely.

[0103] For a lifting pallet, the lifting pallet includes a lifter and a plate body with slots. The lifter uses sensors such as infrared sensors to detect the position of the ball 702. When the ball 702 rolls above the lifting pallet and its position needs to be fixed, the lifter moves upward, and the plate body fixes the ball 702 through the slots. It is easy to understand that the lifter and sensors can each be any suitable existing model.

[0104] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
