Description

Technical Field

[0001] This utility model relates to the field of measuring device technology, specifically a measuring device for urban and rural planning. Background Technology

[0002] Measurement is an important part of urban and rural planning. In existing technology, a distance measuring wheel is used to measure longer distances. Its working principle is based on recording the number of times the wheel rolls and combining it with the circumference of the wheel to accurately calculate the target distance. This tool is easy to operate and does not require complicated procedures, which greatly improves measurement efficiency.

[0003] However, existing rangefinder wheels are prone to deflection or bouncing when encountering obstacles such as stones, which can lead to errors in measurement data. To ensure measurement accuracy, operators have to stop working and clear the obstacles in front of them in time, which affects the work progress and reduces measurement efficiency to some extent. Therefore, it is necessary to design a measurement device that can clear obstacles in front of the rangefinder wheel. Utility Model Content

[0004] The purpose of this invention is to provide a surveying device for urban and rural planning to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a measuring device for urban and rural planning, including a roller, the roller being rotatably mounted on a support, a rotary encoder being mounted on the support, a handle being fixed on the support, and two clearing plates being arranged under the support. When the clearing plates are in the clearing state, the two clearing plates form a triangle, and when the clearing plates are in the retracted state, each clearing plate is parallel to the roller.

[0006] The obstacle clearing plate is fixed under the obstacle clearing linkage. One end of the obstacle clearing linkage is rotatably equipped with one end of the active long linkage, and the other end of the active long linkage is rotatably equipped under the bracket. The other end of the obstacle clearing linkage is rotatably equipped with one end of the driven short linkage, and the other end of the driven short linkage is rotatably equipped under the bracket.

[0007] Preferably, two auxiliary supports are fixed under the main support, and each auxiliary support is equipped with an auxiliary wheel that rotates.

[0008] Preferably, each active long connecting rod is fixed with a worm gear, the worm gear is meshed with a drive worm, the drive worm is mounted on a support, and the support is fixed on a bracket.

[0009] Preferably, each drive worm is fixed with a hexagonal head.

[0010] Preferably, the handle includes a crossbar and a telescopic bar, one end of which is fixed to a bracket, and the other end of which is fixed to a crossbar.

[0011] Preferably, the crossbar is fixed with anti-slip texture.

[0012] Preferably, the rotary encoder is photoelectric.

[0013] Preferably, a storage limiting block is fixed under the bracket. When the clearing plate moves from the clearing state to the storage state, the active long connecting rod can contact the storage limiting block when it rotates. The storage limiting block restricts the further rotation of the active long connecting rod. When the clearing plate rotates from the storage state to the clearing state, the active long connecting rod rotates in the opposite direction and separates from the storage limiting block.

[0014] Preferably, a clearing limit block is fixed under the bracket. When the clearing plate moves from the storage state to the clearing state, the driven short link can contact the clearing limit block when it rotates. The clearing limit block restricts the further rotation of the driven short link. When the clearing plate moves from the clearing state to the storage state, the driven short link rotates in the opposite direction and separates from the clearing limit block.

[0015] Preferably, a storage box is fixed on the bracket.

[0016] When entering the obstacle clearing state, the rotation of each active long link drives the obstacle clearing link, which in turn drives the driven short link to rotate. Because the active long link at the rear of the support has a large range of motion, while the driven short link at the front of the support has a small range of motion, the movement of the obstacle clearing link can cause the two obstacle clearing plates to close into a triangle. After entering the obstacle clearing state, the forward-pushing device can complete the distance measurement work. When there are obstacles such as stones in front of the obstacle clearing plate, the obstacles can be pushed to both sides of the obstacle clearing plate, avoiding the wheels from shifting or jumping due to pressing on the obstacles, thereby improving the accuracy of the measurement, avoiding the need for operators to manually clear the obstacles in front, and improving the measurement efficiency.

[0017] Compared with the prior art, the beneficial effects of this utility model are: since the clearing plate is parallel to the roller in the storage state, it can protect the roller and the rotary encoder. When the clearing plate is placed flat on the ground, the measuring device can be placed flat on the ground stably. Multiple measuring devices can also be stacked by contacting each other through the clearing plate, which facilitates the storage of the measuring devices. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides a technical solution: a measuring device for urban and rural planning, such as... Figure 1 As shown, the device includes a roller 1, which is rotatably mounted on a bracket 2. A rotary encoder 3 is installed on the bracket 2 to measure the number of rotations of the roller 1. Using a rotary encoder 3 to measure the number of rotations of the roller 1 is existing technology. A handle 4 is fixed on the bracket 2. Two clearing plates 5 are arranged under the bracket 2. When the clearing plates 5 are in the clearing state, the two clearing plates 5 form a triangle. When the clearing plates 5 are in the retracted state, each clearing plate 5 is parallel to the roller 1.

[0024] like Figure 2 As shown, the obstacle clearing plate 5 is fixed to the obstacle clearing link 6. One end of the obstacle clearing link 6 is rotatably connected to one end of the active long link 7. The other end of the active long link 7 is rotatably connected to the bracket 2. The other end of the obstacle clearing link 6 is rotatably connected to one end of the driven short link 8. The other end of the driven short link 8 is rotatably connected to the bracket 2. The driven short link 8 is located in front of the bracket 2, and the active long link 7 is located behind the driven short link 8. The length of the active long link 7 is greater than that of the driven short link 8.

[0025] In the stored state, the clearing plate 5 is parallel to the wheel surface of the roller 1, which can block the rotary encoder 3 and prevent the rotary encoder 3 from hitting the ground, thus protecting the rotary encoder 3. When the clearing plate 5 is placed flat on the ground, the measuring device can be placed stably on the ground through the support of the clearing plate 5. Multiple measuring devices can also be stacked by the clearing plate 5 contacting each other, which is convenient for storing the measuring devices.

[0026] When the clearing plate 5 is in its retracted state, the rotation of each active long link 7 drives the clearing link 6 to move, which in turn drives the driven short link 8 to rotate. Since the driven short link 8 in front of the bracket 2 has a large angle of movement, while the active long link 7 behind the driven short link 8 has a small angle of movement, the movement of the clearing link 6 can cause the two clearing plates 5 to close into a triangle. After entering the clearing state, the forward pushing device can complete the distance measurement work. When there are obstacles such as stones in front of the clearing plate 5, the obstacles can be pushed to both sides of the clearing plate 5, avoiding the wheels from shifting or jumping due to pressing on the obstacles, thereby improving the accuracy of the measurement, avoiding the need for operators to manually clear the obstacles in front, and improving the measurement efficiency.

[0027] To improve the stability of the measuring device, such as Figure 1 As shown, there are two auxiliary supports 9 fixed under the support 2, and each auxiliary support 9 is equipped with an auxiliary wheel 10 that rotates.

[0028] To facilitate driving the active long linkage 7, such as Figure 3 As shown, each active long connecting rod 7 is fixed with a worm gear 11, which is meshed with a drive worm 12. The drive worm 12 is rotatably mounted on a support 13, which is fixed to the bracket 2. Each drive worm 12 is fixed with a hexagonal head 14. A wrench can be used to rotate the hexagonal head 14, thereby driving the drive worm 12 to rotate, which in turn drives the worm gear 11 to rotate, and thus drives the active long connecting rod 7 to rotate.

[0029] For easy storage of handle 4, such as Figure 2 As shown, the handle 4 includes a crossbar 15 and a telescopic bar 16. One end of the telescopic bar 16 is fixed to the bracket 2, and the other end of the telescopic bar 16 is fixed to the crossbar 15. The crossbar 15 is fixed with anti-slip texture.

[0030] To facilitate the measurement of the number of rotations of roller 1, the rotary encoder 3 is an existing photoelectric rotary encoder.

[0031] To facilitate locating the storage status, such as Figure 2 As shown, a storage limiting block 17 is fixed under the bracket 2. When the clearing plate 5 enters the storage state from the clearing state, the active long connecting rod 7 can contact the storage limiting block 17 when it rotates. The storage limiting block 17 restricts the further rotation of the active long connecting rod 7. When the clearing plate 5 rotates from the storage state to the clearing state, the active long connecting rod 7 rotates in the opposite direction and separates from the storage limiting block 17.

[0032] To facilitate positioning in the clearing and storage state, a clearing limit block 18 is fixed under the bracket 2. When the clearing plate 5 enters the clearing state from the storage state, the driven short link 8 can contact the clearing limit block 18 when rotating, and the clearing limit block 18 restricts the further rotation of the driven short link 8. When the clearing plate 5 enters the storage state from the clearing state, the driven short link 8 rotates in the opposite direction and separates from the clearing limit block 18.

[0033] For easy storage of tools, such as Figure 1 As shown, a storage box 19 is fixed on the bracket 2.

[0034] Working process: Rotating one drive worm 12 drives the worm wheel 11 to rotate, which in turn drives the active long connecting rod 7 to rotate, which in turn drives the clearing connecting rod 6 to move, which in turn drives the clearing plate 5 to move. The movement of the clearing connecting rod 6 can drive the driven short connecting rod 8 to rotate, so that the driven short connecting rod 8 moves to the clearing limit block 18. The above operation is repeated for the other drive worm 12, so that the driven short connecting rod 8 corresponding to the other clearing plate 5 moves to the corresponding clearing limit block 18, so that the two clearing plates 5 close together to form a triangle and enter the clearing state.

[0035] After the obstacle clearing plate 5 enters the obstacle clearing state, pushing the measuring device forward can complete the distance measurement work. When there are obstacles such as stones in front of the obstacle clearing plate 5, the obstacles can be pushed to both sides of the obstacle clearing plate 5.

[0036] After the measurement is completed, rotate one drive worm gear 12, which in turn drives the worm wheel 11 to reverse, which in turn drives the active long connecting rod 7 to reverse, which in turn drives the lower clearing connecting rod 6 to move in the opposite direction, which in turn drives the clearing plate 5 to move in the opposite direction. The reverse movement of the clearing connecting rod 6 can drive the driven short connecting rod 8 to reverse, so that the active long connecting rod 7 moves to the storage limit block 17. Repeat the above operation on the other drive worm gear 12, so that the active long connecting rod 7 corresponding to the other clearing plate 5 moves to the corresponding storage limit block 17, so that the clearing plate 5 is parallel to the wheel surface of the roller 1 and enters the storage state.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
