Description

Technical Field

[0001] The present invention relates to the technical field of urban and rural planning and design, and specifically provides a measuring device for urban and rural planning and design. Background Art

[0002] Urban and rural planning is a general term for urban system planning, urban planning, town planning, rural planning, and village planning. With the acceleration of the urban-rural integration process, the complexity and precision requirements of urban and rural planning and design are getting higher and higher. In urban and rural planning and design, the measurement work is a fundamental and crucial link, which provides accurate data support for land use planning, infrastructure layout, building design, etc. However, the existing measuring devices have many problems in practical applications and are difficult to meet the needs of modern urban and rural planning and design. Traditional measuring tools, such as level instruments, theodolites, total stations, etc., although widely used in the measurement field, have obvious limitations. They are greatly affected by topographic conditions, which easily lead to inaccurate measurement data and low work efficiency.

[0003] The existing Chinese patent with the publication number CN118582639A includes a fixed ring and a fixed shell arranged above the top of the fixed ring. The top of the fixed shell is fixedly installed with a mounting plate, and the middle of the top of the mounting plate is attached to the measuring instrument body. Clamping components are respectively installed on both sides of the top of the mounting plate, a fixing component is installed at the rear of the fixed shell, and a circular seat is arranged below the bottom of the fixed ring. A stabilizing component is installed at the bottom of the circular seat, and an adjusting component is installed on one side of the top of the circular seat.

[0004] When the above device is in use, through the mutual cooperation between components such as rotating ring A, rotating ring B, sphere, counterweight cylinder, and counterweight ball, it can play a role in automatically leveling the mounting plate after the device is placed, solving the problem of the cumbersome process that requires multiple adjustments by staff in the existing device. However, in the actual use process, since the measuring instrument is fixedly supported on the tripod, when measuring the parameters of different areas, it is necessary for personnel to manually lift the tripod and rotate the measuring instrument to different areas for measurement, which is time-consuming and laborious, resulting in low work efficiency. Therefore, it is difficult to automatically adjust the measuring instrument to rotate in all directions to complete the measurement of parameters in different areas.

[0005] Therefore, we propose a measuring device for urban and rural planning and design. Summary of the Invention

[0015] Preferably, the inner wall of the support ring is rotatably connected to a cylindrical cam for lifting and reciprocating adjustment of the L-shaped rod, and the outer contour of the cylindrical cam is fixedly connected to a toggle ring for personnel to toggle the cylindrical cam for rotational adjustment, and the outer contour of the toggle ring is provided with anti-slip grooves.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. Through the cooperation of the triangular plate, the threaded sleeve rod, and the threaded rod, the expansion and contraction of the support rod can be achieved. When measurement is required, the rotation of the threaded rod drives the threaded sleeve rod and the triangular plate to rise, pushing the support rod to expand and form a stable tripod structure, providing reliable support for the measuring instrument body, improving the stability of the measuring device, ensuring the reliability of the measurement process, and avoiding measurement errors caused by unstable support.

[0018] The expansion and contraction process is smooth and rapid, enabling the erection and storage of the measuring device to be completed in a short time, greatly improving the efficiency of the measurement work. Especially in scenarios where the measurement position needs to be frequently moved, the high efficiency of the adjustment mechanism can significantly reduce the operation time and labor intensity of the measurement personnel.

[0019] 2. Through the cooperation of the lifting block, the inclined slot, and the cylindrical block, the omnidirectional automatic rotation of the measuring instrument body can be achieved. When the triangular plate rises to the limit position, the lifting block pushes the locking block to unlock the threaded sleeve rod, and the rotation of the threaded rod drives the threaded sleeve rod and the cylindrical sleeve rod to move, thereby driving the measuring instrument body to perform omnidirectional rotation. It can be automatically adjusted without manual intervention, greatly improving the measurement efficiency and reducing the workload of the measurement personnel.

[0020] The omnidirectional rotation function enables the measuring instrument to cover a wider measurement area, completing measurement tasks in multiple directions without frequently moving the measuring device, improving the continuity of the measurement work, and ensuring the integrity and consistency of the measurement data, providing more comprehensive and accurate data support for urban and rural planning and design.

[0021] 3. Through the cooperation of the inclined plane rod, the torsion spring, the second block, and the first block, the insertion rod can be quickly inserted into the soil, further enhancing the fixed stability of the measuring device on the ground. During the measurement process, especially in the face of adverse weather conditions such as strong winds, the ejection mechanism can ensure that the measuring device is firmly fixed on the ground, avoiding measurement errors and equipment damage caused by the loosening or tipping of the device.

[0022] The quick insertion function of the insertion rod not only improves the stability of the measuring device but also reduces the operation time of the measurement personnel when fixing the device. Traditional measuring devices usually require manual insertion of the support feet into the ground, which is not only time-consuming and laborious but also may cause the device to be unstable due to insecure insertion. The design of the ejection mechanism enables the insertion rod to be inserted into the soil instantly, greatly improving the fixing efficiency and stability of the measuring device.

[0023] IV. Through the cooperation of the L-shaped rod, fixed rod, support groove, circular block and the third spring, the angle of the measuring instrument body can be automatically adjusted to keep it always in a horizontal state. In actual measurement, since the ground is often uneven, the angle of the measuring instrument body may be affected, resulting in inaccurate measurement data. The design of the leveling mechanism can adjust the angle of the measuring instrument through mechanical transmission to ensure that the measuring instrument is always in a horizontal state, thereby improving the accuracy of the measurement data.

[0024] The automatic leveling function reduces the operation time of the measuring personnel during the leveling process and improves the efficiency of the measurement work. Traditional measuring devices usually require manual adjustment of the angle of the measuring instrument by personnel, which is not only time-consuming and laborious but also prone to introducing errors due to improper operation. The automatic design of the leveling mechanism enables the measuring instrument to complete leveling in a short time, ensuring the smooth progress of the measurement work.

[0025] Through the combined use of the above structures, the problem that in the actual use process of the existing device, since the measuring instrument is fixedly supported on the tripod, when measuring the parameters of different areas, it is necessary for personnel to manually lift the tripod and rotate the measuring instrument to different areas for measurement, which is time-consuming and laborious, resulting in low work efficiency, and it is difficult to automatically adjust the measuring instrument to rotate omnidirectionally to complete the measurement of parameters in different areas is solved.

[0041] Embodiment Two:

[0042] On the basis of Embodiment One, further:

[0043] The adjusting mechanism includes moving grooves 301 opened on the inner sides of the three support rods 3. The inner walls of the three moving grooves 301 are connected with a triangular plate 9 that moves up and down to push the support rods 3 to expand and contract. The triangular plate 9 is penetrated and rotatably connected with a threaded sleeve rod 11, and the end of the threaded sleeve rod 11 penetrates to the inner wall of the cylindrical sleeve rod 6 and is axially movably connected. The base 1 is penetrated and fixedly rotatably connected with a threaded rod 10 driven by a power mechanism to rotate, and the end of the threaded rod 10 penetrates to the inner wall of the threaded sleeve rod 11 and is screwed.

[0044] A cavity 901 is opened on one side of the triangular plate 9 close to the threaded sleeve rod 11. The inner wall of the cavity 901 is horizontally movably connected with a locking block 12 for locking the threaded sleeve rod 11. A locking groove 111 adapted to the outer contour of the locking block 12 is opened on the outer contour of the threaded sleeve rod 11. A first spring 13 for guiding the locking block 12 to move back and forth is fixedly connected to the opposite surfaces of the locking block 12 and the cavity 901.

[0045] When in use, through the moving groove 301 opened on the support rod 3 and the triangular plate 9 arranged on the moving groove 301, the triangular plate 9 can be connected in a lifting and moving manner on the inner wall of the moving groove 301. And the threaded sleeve rod 11 arranged on the triangular plate 9 is rotationally supported on the triangular plate 9, and the threaded sleeve rod 11 is axially movably connected on the inner wall of the cylindrical sleeve rod 6 to ensure the stability of the lifting and moving of the triangular plate 9 on the inner wall of the moving groove 301. Through the threaded rod 10 arranged on the base 1, and the threaded rod 10 is driven to rotate by the motor after being energized, so that the motor can drive the threaded rod 10 to rotate axially and reciprocally on the base 1.

[0046] Through the cavity 901 opened on the triangular plate 9 and the locking block 12 arranged on the cavity 901, the cavity 901 can support the moving direction of the locking block 12. Through the first spring 13 arranged on the locking block 12 and the locking groove 111 opened on the threaded sleeve rod 11, the first spring 13 can be pushed by its own elastic force to move the locking block 12 to the inner wall of the locking groove 111, realizing the locking of the threaded sleeve rod 11. And the threaded rod 10 penetrates through the inner wall of the threaded sleeve rod 11 and is screwed. Along with the axial reciprocating rotation of the threaded rod 10, further, the threaded sleeve rod 11 can drive the triangular plate 9 to move up and down reciprocally under the action of the threaded rod 10, and at the same time, the threaded sleeve rod 11 axially reciprocates on the inner wall of the cylindrical sleeve rod 6.

[0048] Embodiment Three:

[0049] On the basis of Embodiment Two, further:

[0050] The transmission mechanism includes that a lifting block 14 is penetrated and connected in a lifting and moving manner on one side of the triangular plate 9 close to the locking block 12. An inclined slot 141 for pulling the locking block 12 to lock and unlock the threaded sleeve rod 11 is opened on the lifting block 14. A cylindrical block 15 is fixedly connected to one side of the locking block 12 close to the lifting block 14, and the cylindrical block 15 penetrates through the inner wall of the inclined slot 141 and is movably connected.

[0051] When in use, the lifting block 14 provided on the triangular plate 9 is connected to the lifting block 14 on the triangular plate 9. The inclined groove 141 provided on the lifting block 14 and the columnar block 15 provided on the locking block 12 enable the columnar block 15 to support the position of the locking block 12 under the action of the inclined groove 141. When the triangular plate 9 moves to the extreme position in the upward index finger direction, and the end of the lifting block 14 conflicts with the bottom of the circular plate 5, the triangular plate 9 moves toward the end of the lifting block 14, so that the columnar block 15 is in the Under the action of the inclined groove 141, the locking block 12 can be pulled to move in the direction away from the threaded sleeve 11 and disengage from the locking groove 111.

Through the second spring 22 provided on the moving block 18, and the second spring 22 supports the position of the moving block 18, so as to drive the second spring 22 to perform reset movement subsequently. Through the insertion rod 19 provided on the moving block 18 and the ejection mechanism provided on the first track plate 16, the ejection mechanism can push the insertion rod 19 to quickly insert into the soil under the action of the elastic force of the second spring 22, further improving the measurement stability of the measuring instrument body 8, and avoiding the problems that the measuring device is offset or toppled in bad weather with strong wind, resulting in inaccurate measurement data and damage to the measuring instrument body 8.

[0057] The ejection mechanism includes that a fixed block 23 is fixedly connected to one side of each first track plate 16 away from the inclined plane block 20. The end of each fixed block 23 is penetrated and rotatably connected with a fixed shaft to a inclined plane rod 24. A torsion spring 241 for guiding the inclined plane rod 24 to perform reset rotation is fixedly connected to the opposite surfaces of each inclined plane rod 24 and the fixed block 23. A second clamping block 242 for supporting the moving block 18 is fixedly connected to one side of each inclined plane rod 24 close to the moving block 18. A first clamping block 181 engaged with the second clamping block 242 is fixedly connected to one end of each moving block 18 close to the limiting rod 21.

[0058] A second rack 27 is fixedly connected to one side of each second track plate 17 away from the fixed block 23. A transmission gear 26 is rotatably connected to one side of each support rod 3 close to the second rack 27. A first rack 25 is fixedly connected to one side of each of the three ends of the triangular plate 9 close to the transmission gear 26, and the two sides of the transmission gear 26 are respectively engaged and transmitted with the adjacent ends of the first rack 25 and the second rack 27.

[0059] During use, through the fixing block 23 provided on the first track plate 16, the fixing block 23 is fixedly supported on the first track plate 16, and the inclined surface rod 24 provided on the fixing block 23 enables the inclined surface rod 24 to be rotatably supported on the fixing block 23. Through the torsion spring 241 provided on the inclined surface rod 24, and the torsion spring 241 supports the inclined surface rod 24, the inclined surface rod 24 can be fitted to the surface of the moving block 18 under the action of the torsion spring 241. Through the second clamping block 242 provided on the inclined surface rod 24 and the first clamping block 181 provided on the moving block 18, the second clamping block 242 can be kept in a clamped state with the first clamping block 181 under the action of the inclined surface rod 24, realizing the support for the moving block 18.

[0060] Through the second rack 27 provided on the second track plate 17 and the first rack 25 provided on the triangular plate 9, the second rack 27 and the first rack 25 are respectively fixedly supported on the second track plate 17 and the triangular plate 9. Through the transmission gear 26 provided on the support rod 3, both sides of the transmission gear 26 can perform meshing transmission on the adjacent ends of the second rack 27 and the first rack 25.

[0061] When the triangular plate 9 moves in the upward vertical direction, and the first rack 25 can move synchronously with the triangular plate 9, the transmission gear 26 can drive the second track plate 17 and the inclined surface block 20 to move towards the direction close to the moving block 18 through the second rack 27 under the action of the triangular plate 9. And the second clamping block 242 supports the moving block 18 through the first clamping block 181. At this time, the moving block 18 remains stationary, enabling the second spring 22 to be squeezed and contracted under the action of the inclined surface block 20. When the triangular plate 9 moves upward to the limit position, and the inclined surface on the inclined surface block 20 can contact and move with the inclined surface of the inclined surface rod 24, the inclined surface rod 24 can drive the second clamping block 242 to rotate away from the moving block 18 under the action of the inclined surface block 20, and the second clamping block 242 is disengaged from the first clamping block 181. Thus, the moving block 18 can drive the insertion rod 19 to perform a reset movement away from the inclined surface block 20 under the elastic force of the second spring 22, enabling the moving block 18 to drive the insertion rod 19 to move quickly and insert into the soil, further improving the stability of the measuring device and avoiding the problems that the measuring device is offset or toppled in bad weather with strong winds, resulting in inaccurate measurement data and damage to the measuring instrument body 8.

[0062] When the triangular plate 9 performs a reset movement in the downward vertical direction, the above structure synchronously performs a reset movement in the opposite direction.

The leveling mechanism includes an L-shaped rod 29 that passes through the U-shaped frame 7 and is connected to the measuring instrument body 8 for leveling the angle, and the end of the measuring instrument body 8 close to the L-shaped rod 29 is fixedly connected to a fixing rod 28, and the end of the fixing rod 28 away from the measuring instrument body 8 is provided with a support groove 281 for movably supporting the end of the L-shaped rod 29, and a circular block 30 is fixedly connected to the outer contour of the L-shaped rod 29 near the bottom end, and a third spring 31 is fixedly connected to the opposite surface of the circular block 30 and the U-shaped frame 7 to guide the L-shaped rod 29 to reset.

[0066] The inner wall of the support ring 4 is rotatably connected to a cylindrical cam 32 for adjusting the L-shaped rod 29 to move up and down. The outer contour of the cylindrical cam 32 is fixedly connected to a toggle ring 33 for personnel to toggle the cylindrical cam 32 for rotational adjustment, and the outer contour of the toggle ring 33 is provided with anti-slip grooves.

[0067] During use, the L-shaped rod 29 provided on the U-shaped frame 7 enables the L-shaped rod 29 to be lifted and moved on the U-shaped frame 7, and the fixed rod 28 provided on the measuring instrument body 8 fixes the fixed rod 28 on the measuring instrument body 8. Through the support groove 281 opened on the fixed rod 28, the fixed rod 28 can movably support the end of the L-shaped rod 29 on the inner wall. Through the circular block 30 provided on the L-shaped rod 29, the circular block 30 is fixedly supported on the L-shaped rod 29, and the third spring 31 provided on the circular block 30 enables the third spring 31 to support the position of the L-shaped rod 29 through the circular block 30.

[0068] The cylindrical cam 32 is rotatably supported on the inner wall of the support ring 4 by the cylindrical cam 32 provided on the support ring 4, and the bottom end of the L-shaped rod 29 can come into contact with the inclined surface of the cylindrical cam 32 under the elastic force of the third spring 31. The toggle ring 33 is provided on the cylindrical cam 32, and the anti-slip grooves are provided on the toggle ring 33, so that a person can drive the cylindrical cam 32 to rotate back and forth on the inner wall of the support ring 4 by toggling the toggle ring 33. As the toggle ring 33 rotates back and forth, the L-shaped rod 29 can be lifted and reciprocated on the U-shaped frame 7.

[0069] Since the ground is mostly uneven, it is likely to cause the measuring angle of the measuring instrument body 8 to be relatively high or low. When the measuring angle of the measuring instrument body 8 is low, rotate the lowest end of the inclined surface of the cylindrical cam 32 towards the L-shaped rod 29. At this time, the circular block 30 drives the L-shaped rod 29 to move downward under the elastic force of the third spring 31, so that the fixing rod 28 can rotate the measuring angle of the fixing rod 28 upward under the pull of the L-shaped rod 29. When the measuring angle of the measuring instrument body 8 is high, rotate the highest end of the inclined surface of the cylindrical cam 32 towards the L-shaped rod 29. Then, the L-shaped rod 29 moves upward in the vertical direction under the action of the inclined surface of the cylindrical cam 32, and the third spring 31 is compressed and contracted under the action of the circular block 30. At the same time, the fixing rod 28 can rotate the measuring angle of the fixing rod 28 downward under the push of the L-shaped rod 29.

[0070] Furthermore, it is realized that during the actual use of the existing device, the measuring instrument can be automatically adjusted to rotate in all directions to complete the measurement of parameters in different areas, which is convenient to use and better than traditional products.

[0071] The standard parts used in this embodiment can be directly purchased from the market. For the non-standard structural components described in the specification and drawings, they can also be directly processed without doubt according to the existing technical knowledge. At the same time, the connection methods of each component adopt the mature conventional means in the existing technology, and the machines, parts and equipment all adopt the conventional models in the existing technology, so no specific description will be made here.

[0072] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
