Description

Technical Field

[0001] This utility model relates to the field of surveying and mapping technology, specifically to a surveying and mapping device for urban road traffic planning and design. Background Technology

[0002] In urban road traffic planning and design, surveying is a core preliminary step. The accuracy of the total station, as a core surveying device, directly determines the accuracy of the survey data. Currently, total stations are generally set up on tripods. After centering, the coarse leveling process requires the operator to observe the bubble meter on the total station and adjust the tripod leg heights based on the bubble's offset. This requires holding the leg to be adjusted with one or both hands while ensuring the other two legs remain fixed to prevent centering misalignment. The height of the three legs needs repeated adjustments and corrections, making the process cumbersome and demanding a high level of operator skill.

[0003] Urban road traffic surveys are often conducted in complex outdoor locations such as roads and intersections. Tripod legs are easily affected by uneven ground and debris on the road surface. When adjusting the legs, the support may sway, which not only further increases the difficulty of leveling and reduces the efficiency of leveling, but may also cause the completed centering position to become invalid due to the movement of the legs, requiring re-centering and leveling, which seriously affects the progress of the overall survey work. Utility Model Content

[0004] Purpose of the utility model: To provide a surveying device for urban road traffic planning and design, so as to solve the above-mentioned problems existing in the prior art.

[0005] Technical solution: A surveying device for urban road traffic planning and design, comprising a support, an adjustment unit, and a surveying unit configured on top of the support via the adjustment unit.

[0006] A mounting plate is provided at the top of the bracket;

[0007] The survey unit is mounted on the mounting plate by adjusting the unit configuration;

[0008] The adjustment unit is mounted on the mounting plate and is suitable for coarse leveling of the survey unit; among which,

[0009] A support base is provided at a corresponding position on the top edge of the mounting plate, and the top of the support base is arc-shaped and concave to form a support groove. The adjustment unit includes:

[0010] A support body is rotatably configured in a support groove. Both ends of the support body extend radially along the mounting plate to a predetermined length. The end of the support body near the outer side of the mounting plate is the first end. The first end is connected to a locking unit, which is adapted to lock the rotational working position of the support body.

[0011] The support plate has a through hole in the middle for mounting the survey unit; the support plate is located above the mounting plate and one end is rotatably configured with the support body, while the other end extends to a predetermined length; a support assembly is provided between the bottom of the support plate and the support body, and the support assembly is adapted to adjust the rotation angle of the support plate and lock it.

[0012] Furthermore, the locking unit includes a support vertical plate disposed on the side of the support base; a threaded rod, one end of which is disposed at the first end of the support body, and the other end extending along the central axis of the support body and movably passing through the support vertical plate; and a bolt, which is threadedly adapted to the threaded rod and can abut against the side of the support vertical plate during the locking operation.

[0013] Furthermore, the support body is provided with a connecting column at a corresponding position on the second end peripheral wall, and the two sides of the connecting column are rotatably configured with a corresponding end of the bearing plate via a rotating shaft.

[0014] Furthermore, the support assembly includes two symmetrically distributed support crossbars, which are configured at corresponding positions on the second end peripheral wall of the support body and are distributed relative to the rotation axis; and two telescopic rods, with the fixed part and the telescopic end respectively movably connected to the bottom of the support crossbars and the extension end of the bearing plate.

[0015] Furthermore, a rubber pad layer is provided on the outer wall of the supporting vertical plate.

[0016] Beneficial effects: This utility model relates to a surveying device for urban road traffic planning and design. The adjustment unit can realize the angle adjustment of the surveying unit in two different directions. During coarse leveling, only the rotation angle of the bearing plate needs to be adjusted by controlling the extension and retraction of the telescopic rod of the support component, and the position of the support body in the support groove needs to be adjusted. This can complete the coarse leveling operation of the total station, replacing the traditional method of repeatedly adjusting the height of the tripod legs. No multiple people are required, and a single person can complete the operation, which greatly shortens the time spent on coarse leveling and improves the overall efficiency of the surveying operation. During the coarse leveling process, there is no need to move the support or adjust the height of the legs. The support always maintains the initial stable state, reducing repetitive work steps and further improving the continuity of the surveying operation. Attached Figure Description

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0025] In existing technology, total stations are generally mounted on tripods. After being installed on the top of the tripod, centering and leveling operations are required. During coarse leveling, the bubble meter of the total station is usually observed. Based on the position of the bubble, both hands need to hold the corresponding tripod leg while ensuring that the other tripod legs remain stationary (to ensure the centering position). Then, the height of the tripod legs is adjusted. This process of adjusting the height of the three tripod legs is repeated, which is inconvenient.

[0026] Therefore, this application designs a surveying device for urban road traffic planning and design. Based on the existing technology, an adjustment unit is set up to perform coarse adjustment of the total station (surveying device) without adjusting the height of the tripod legs. The stability of the tripod is ensured during the leveling process, and it is convenient for coarse adjustment.

[0027] like Figures 1-6 The surveying device for urban road traffic planning and design involved in this utility model mainly includes a support 1, an adjustment unit 3, and a surveying unit 2 configured on the top of the support 1 via the adjustment unit 3. A mounting plate 14 is provided at the top of the support 1; the surveying unit 2 is configured on the mounting plate 14 via the adjustment unit 3; the adjustment unit 3 is configured on the mounting plate 14 and is suitable for coarsely leveling the surveying unit 2.

[0028] In this embodiment, the surveying unit 2 is a total station, which includes a bubble meter. Coarse leveling is performed by adjusting the unit 3, which relies on observing the bubble meter. It should be noted that after coarse leveling, the fine adjustment mechanism built into the total station is used for precise adjustment. The center connection screw can be loosened to move the total station and adjust the center position. This is prior art and will not be elaborated in detail in this application.

[0029] In this embodiment, a support base 4 is disposed at a corresponding position on the top edge of the mounting plate 14, and the top of the support base 4 is arc-shaped and concave to form a support groove 5. The adjustment unit 3 includes:

[0030] The support body 6 is rotatably configured in the support groove 5. Both ends of the support body 6 extend radially along the mounting plate 14 to a predetermined length. The end of the support body 6 near the outer side of the mounting plate 14 is the first end, which is connected to a locking unit. The locking unit is suitable for locking the rotational working position of the support body 6. The arc-shaped support groove 5 of the support seat 4 is adapted to the support body 6 to ensure the smoothness and stability of the rotation of the support body 6.

[0031] The bearing plate 7 has a through hole in the middle, which is suitable for installing the survey unit 2 (the total station is installed in accordance with the existing technology, and is configured on the bearing plate 7 by a central connecting screw); the bearing plate 7 is located above the mounting plate 14 and one end is rotatably configured with the support body 6, and the other end extends to a predetermined length; a support component is provided between the bottom of the bearing plate 7 and the support body 6, which is suitable for adjusting the rotation angle of the bearing plate 7 and locking it.

[0032] It should be noted that the rotation direction of the bearing plate 7 is different from that of the support body 6. Therefore, by observing the bubble meter and adjusting the position of the total station in the above two directions, the plane on which the total station is mounted can be determined, thereby achieving coarse leveling.

[0033] In some preferred embodiments, the locking unit includes a support vertical plate 8 disposed laterally on the support base 4; a threaded rod 9, one end of which is disposed at the first end of the support body 6, and the other end extending along the central axis of the support body 6 and movably passing through the support vertical plate 8; and a bolt 10, threadedly fitted to the threaded rod 9, which can abut against the side of the support vertical plate 8 during locking operations. The outer wall of the support vertical plate 8 is provided with a rubber pad layer, which increases friction when the bolt 10 is tightened, thus locking the working position of the support body 6.

[0034] In some preferred embodiments, the support body 6 is provided with a connecting column 11 at a corresponding position on the second end peripheral wall, and the two sides of the connecting column 11 are rotatably configured with a corresponding end of the bearing plate 7 via a rotating shaft.

[0035] The bearing plate 7 can be roughly H-shaped, including a pair of long plates and a connecting plate between the long plates. One end of the long plate is rotatably mounted on the side of the connecting column 11 via a damping shaft. The connecting plate has through holes.

[0036] The support assembly includes two symmetrically distributed support crossbars 12, which are positioned at corresponding locations on the second end periphery of the support body 6 and are distributed relative to the rotation axis. Two telescopic rods 13 have fixed and telescopic ends that are movably connected to the support crossbars 12 and the bottom of the extension end of the bearing plate 7, respectively. Specifically, these connections can be hinged or rotatable. The telescopic rods 13 can be customized electric telescopic rods, with their stroke and thrust customized according to specific usage scenarios. Each telescopic rod 13 has a self-locking structure; after the telescopic end extends to the corresponding working position, it can self-lock, locking the current working position.

[0037] The bearing plate 7 and the support body 6 are connected by a rotating shaft. The support components are symmetrically distributed, so that the bearing plate 7 is subjected to uniform force, avoiding tilting and shaking after the survey unit 2 is erected. The overall structure of the device is compact and highly stable.

[0038] The telescopic pole 13 can be electrically connected to a corresponding controller. The controller is used to control the extension, retraction, and start / stop of the telescopic pole 13. The operator can control the extension, retraction, and start / stop of the telescopic pole 13 through corresponding buttons. The two telescopic poles 13 are synchronous telescopic poles 13. The electric telescopic pole 13 has a power supply module, which is electrically connected to the controller. Specifically, the controller and power supply module can be placed inside the support body 6. The specific electrical connection and placement are existing technologies and will not be described in detail here.

[0039] In practical use, the operator sets up the bracket 1 at the survey point of the urban road traffic planning, adjusts the three legs of the bracket 1 to make the mounting plate 14 roughly horizontal, and then assembles the total station into the through hole of the bearing plate 7 through the center connecting screw to complete the centering operation of the total station and ensure that the laser point-to-point alignment of the total station is accurate with the survey point.

[0040] The operator observes the bubble meter integrated with the total station. If the bubble deviates radially along the mounting plate 14, the operator rotates the support body 6, causing it to rotate in an arc along the support groove 5 of the support base 4. This causes the bearing plate 7 and the total station to rotate synchronously until the bubble returns to its original position in that direction. Then, the operator tightens the bolts 10, ensuring they press against the rubber pad on the outside of the support vertical plate 8, thus locking the position of the support body 6. If the bubble deviates along the length of the bearing plate 7, the operator activates the synchronous electric telescopic rod 13 via an external button. This controls the extension or retraction of the telescopic rod 13, causing the bearing plate 7 to rotate around its axis. The operator adjusts the tilt angle of the bearing plate 7 until the bubble meter's bubble is completely back in its original position. Then, the operator stops the telescopic rod 13, using its self-locking structure to lock its length, thus locking the angle of the bearing plate 7.

[0041] Then, the operator can use the fine-tuning mechanism built into the total station to perform fine-tuning and leveling to further ensure the levelness of the total station. After the fine-tuning and leveling work is completed, the total station can be started to carry out surveying work for urban road traffic planning and collect survey data such as road coordinates, elevation, and distance.

[0042] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes in form and detail may be made to the present invention without departing from the spirit and scope of the appended claims.
