Description

Technical Field

[0001] This invention relates to the field of urban planning surveying technology, specifically to a verticality measuring device for urban planning. Background Technology

[0002] For large buildings such as skyscrapers, verticality measurement is a key step in ensuring their structural safety. By accurately measuring the verticality of a building, deviations that may occur during construction can be detected in a timely manner, preventing the building's center of gravity from shifting due to excessive verticality deviation. This reduces uneven stress on the structure and prevents the risk of the building tilting or even collapsing during use.

[0003] Most existing verticality measuring devices use a plumb line to measure verticality. However, plumb line measurement mainly relies on visual observation of the relative position of the plumb line and the edge of the object being measured to determine verticality. It is difficult to be accurate to small scale values. This process may take a long time, especially in the presence of wind or other interference factors. Moreover, plumb line measurement can usually only measure one point at a time. When measuring the verticality of multiple points or the entire object, a lot of time is required.

[0019] The present invention provides a verticality measuring device for urban planning, the advantages of which include:

[0020] 1. By setting up a verticality measuring mechanism, the tilt angle of the wall to be measured can be determined by observing the position of the pointer on the indicator plate. The pointer can directly indicate the specific value of verticality, and construction workers or surveyors can read the data intuitively.

[0021] 2. By using stickers, the measured data can be recorded on the wall to be measured. During the construction process, verticality may need to be measured multiple times. By attaching the measurement data of different stages to the wall in the form of stickers, the changes in data at different times can be compared intuitively, the trend of wall verticality changes can be clearly understood, and new verticality deviations can be detected in time.

[0022] 3. By incorporating a windproof mechanism, the center of gravity of the plumb bob can be lowered in windy conditions. A lower center of gravity makes the plumb bob more stable during swaying. According to the principle of gravity, the lower the center of gravity of an object, the better its stability. When the center of gravity of the plumb bob is lowered, it is less likely to deviate from its vertical direction when it is swayed by external forces, and it can return to a stable vertical state more quickly, thereby improving the accuracy of the measurement.

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Reference Figures 1-8This technical solution provides a verticality measuring device for urban planning, specifically including a base plate 1. A verticality measuring mechanism 2 is installed on the top of the base plate 1. The verticality measuring mechanism 2 includes a main rod 201, a roller 203, and a rope 205. The main rod 201 is rotatably mounted on the top of the base plate 1. Handrails are installed on both sides of the main rod 201, and control buttons are provided on the top of the handrails. The operator can rotate the main rod 201 to make it fit tightly against the wall to be measured. A first side plate 217 is fixedly installed on the side of the main rod 201, and a first mounting base 202 is fixedly installed on the bottom of the first side plate 217. The roller 203 is rotatably installed inside the first mounting base 202, and a rotating... Handle 204 is fixedly connected to roller 203 by rotation. Thread 205 is wound around the surface of roller 203. A plumb bob 206 is detachably installed at the end of thread 205. A windproof mechanism 4 is installed inside the plumb bob 206. When measuring the verticality of a wall, the operator rotates handle 204, causing roller 203 to rotate and releasing thread 205 from its surface. In this situation, the plumb bob 206 remains perpendicular to the horizontal plane under the influence of gravity. A second side plate 207 is fixedly installed on the side of the main rod 201. A sliding groove 208 is formed on the surface of the second side plate 207. A sliding rod 209 is fixedly installed inside the sliding groove 208. A first... The threaded rod 210 has a threaded block 211 threaded onto its surface. The threaded block 211 is slidably connected to the slide rod 209. A straight groove 212 is formed on the surface of the threaded block 211. A rope 205 passes through the straight groove 212 to the bottom of the threaded block 211. Because the rope 205 remains perpendicular to the horizontal plane under the action of the plumb bob 206, when the wall under test tilts, the angle between the second side plate 207 and the rope 205 changes. Therefore, the intersection point between the rope 205 and the second side plate 207 also changes. Under the action of the plumb bob 206, the change in the intersection point of the rope 205 will cause the position of the threaded block 211 inside the sliding groove 208 to change. Therefore, the threaded block 211 can be moved along the first threaded rod 210. Threaded sliding occurs on the surface of the sliding groove 208. A first gear 213 is rotatably mounted on both sides of the inner side of the sliding groove 208. A second gear 214 is fixedly mounted on both ends of the first threaded rod 210. The first gear 213 meshes with the second gear 214. An indicator plate 215 is fixedly mounted on the side of the second side plate 207. A pointer 216 is rotatably mounted on the side of the indicator plate 215. The pointer 216 is fixedly connected to the right-side second gear 214. When the threaded block 211 moves, it drives the first threaded rod 210 to rotate. The rotating first threaded rod 210 drives the second gear 214 to rotate. The rotating second gear 214 drives the first gear 213 to rotate. The rotating first gear 213 drives the pointer 216 to rotate.Workers can determine the tilt angle of the wall being measured by observing the position of pointer 216 on indicator plate 215. Pointer 216 directly indicates the specific value of verticality, allowing construction workers or surveyors to intuitively read the data. Compared to other more indirect methods, such as observing the swing of a plumb bob, the value displayed by the pointer is more accurate, precise to specific graduations, reducing human error and improving measurement precision.

[0035] Reference Figures 1-8This embodiment also proposes that a marking mechanism 3 is installed inside the main rod 201. The marking mechanism 3 includes a first mounting cavity 301, which is opened inside the main rod 201. A fixing plate 302 is fixedly installed inside the first mounting cavity 301. A second mounting seat 303 is fixedly installed on the top of the fixing plate 302. A first bevel gear 304 is rotatably installed on the side of the second mounting seat 303. A second bevel gear 305 is rotatably installed on the inner wall of the first mounting cavity 301. The second bevel gear 305 is fixedly connected to the left second gear 214. When the first threaded rod 210 rotates, the rotating first threaded rod 210 can drive the left second gear 214. The second gear 214 rotates, and the rotating left part of the second gear 214 can drive the second bevel gear 305 to rotate. The rotation of the second bevel gear 305 can drive the first bevel gear 304 to rotate. The main rod 201 has a second mounting cavity 306 inside. The first mounting plate 307 is fixedly installed inside the second mounting cavity 306. The bottom of the first mounting plate 307 is fixedly installed with a third mounting seat 308. The first take-up roller 309 is rotatably installed inside the third mounting seat 308. The first pulley 310 is rotatably installed on the side of the third mounting seat 308. The first pulley 310 is fixedly connected to the first take-up roller 309. The second mounting seat... A second pulley 311 is rotatably mounted on the side of 303. The second pulley 311 is fixedly connected to the first bevel gear 304. When the first bevel gear 304 rotates, it can drive the second pulley 311 to rotate. The first pulley 310 is connected to the second pulley 311 via a belt. A second mounting plate 312 is fixedly mounted inside the second mounting cavity 306. A fourth mounting seat 313 is fixedly mounted on the top of the second mounting plate 312. A first unwinding roller 314 is rotatably mounted inside the fourth mounting seat 313. A perforated marking tape 315 is wound between the first unwinding roller 314 and the first take-up roller 309. The second mounting plate 312... A spray can 328 is fixedly installed on the top of the device. The top of the spray can 328 is connected to a nozzle 329 via a hose. The rotation of the second pulley 311 can drive the first pulley 310 to rotate, and the rotation of the first pulley 310 can drive the first take-up roller 309 to rotate, which in turn can drive the hollow marking ruler 315 to move up and down. The hollow marking ruler 315 has angle data engraved on its surface. After the worker observes that the plumb bob 206 is stable, he presses the button on the handle to start the spray can 328. The paint is sprayed out through the hose and the nozzle 329, and the paint is sprayed through the hollow marking ruler 315.

[0036] Reference Figures 1-8This embodiment also proposes that a second unwinding roller 316 and a second take-up roller 317 are rotatably mounted inside the second mounting cavity 306. A marking sticker 318 is wound between the second unwinding roller 316 and the second take-up roller 317. Paint is sprayed onto the surface of the marking sticker 318 through a perforated marking ruler 315. A motor 319 is fixedly mounted at the bottom of the inner cavity of the first mounting cavity 301. A third pulley 320 is fixedly mounted at the output end of the motor 319. A fourth pulley 321 is fixedly mounted on the surface of the second take-up roller 317. The third pulley 320 is connected to the fourth pulley 321 via a belt. When the plumb bob 206 is stable, the operator starts the motor 319. The motor 319 can... The rotation of the third pulley 320 drives the fourth pulley 321, which in turn drives the second take-up roller 317. The second take-up roller 317 is connected to the second unwind roller 316 via a pulley set. The rotation of the second take-up roller 317 drives the second unwind roller 316, which in turn causes the marking sticker 318 to move upward. A rotating shaft 322 is rotatably mounted inside the second mounting cavity 306. The rotating shaft 322 is connected to the second unwind roller 316 via a pulley set. A rotating disk 323 is fixedly mounted at the end of the rotating shaft 322. The interior of the second mounting cavity 306 is fixedly... A bracket 324 is installed, and a reciprocating rod 325 is slidably installed inside the bracket 324. A push plate 326 is fixedly installed at the end of the reciprocating rod 325. An eccentric plate 327 is rotatably installed at the eccentric part of the rotating disk 323. The end of the eccentric plate 327 is rotatably connected to the reciprocating rod 325. When the second unwinding roller 316 rotates, it can drive the rotating shaft 322 to rotate. The rotating shaft 322 can drive the rotating disk 323 to rotate, which in turn can drive the eccentric plate 327 to rotate eccentrically. This causes the reciprocating rod 325 to reciprocate inside the bracket 324, thereby driving the push plate 326 to reciprocate. The push plate 326 can move the marking sticker 318. The extrusion and cutting process allows the marking sticker 318 to be adhered to the wall surface to be tested. Before the marking sticker 318 moves upward, the nozzle 329 has already sprayed the marking sticker 318. Therefore, the marking mechanism 3 can record the measured data on the wall surface through the marking sticker 318. During the construction process, verticality measurements may need to be performed multiple times. The measurement data at different stages are sequentially pasted on the wall surface in the form of stickers. This allows for a direct comparison of the data changes at different times, a clear understanding of the trend of wall verticality changes, and timely detection of any new verticality deviations on the wall surface. This helps to adjust the construction process or take corrective measures in a timely manner and is beneficial for comparison after the repair is completed.

[0037] Reference Figures 1-8This embodiment also proposes a windproof mechanism 4 including a first storage chamber 401, which is located inside the plumb bob 206. A second storage chamber 402 is located at the bottom of the first storage chamber 401. A return channel 403 is provided between the second storage chamber 402 and the first storage chamber 401. Two return channels 403 are provided, and one-way valves are provided inside the two return channels 403. Fluid is stored inside the first storage chamber 401. A through channel 404 is provided between the first storage chamber 401 and the second storage chamber 402. A drive shaft 405 is rotatably mounted on the top of the plumb bob 206. A baffle 406 is fixedly mounted on the surface of the drive shaft 405. The drive shaft 405 extends to the bottom of the plumb bob 206. A fan blade 407 is fixedly mounted on the surface of the drive shaft 405. A mounting box 408 is fixedly mounted on the bottom of the plumb bob 206. The mounting box 408 has two rolling grooves 409 inside. Rolling balls 410 are rolled inside the two rolling grooves 409. When the plumb bob 206 is used for verticality measurement, if strong winds are encountered, the plumb bob 206... 06 sways under the influence of wind. The swaying of the plumb bob 206 causes the two balls 410 to roll inside the rolling groove 409. The rolling of the balls 410 strikes the fan blade 407, causing it to rotate. This, in turn, drives the drive shaft 405 to rotate. The rotating drive shaft 405 then drives the baffle 406 to rotate, exposing the through groove 404. The fluid inside the upper first storage chamber 401 flows through the through groove 404 into the lower second storage chamber 402, causing the plumb bob 206 to sway. The center of gravity is lowered, reducing the amplitude of the swing. After use, the staff inverts the plumb bob 206, and the fluid inside the second storage chamber 402 flows back into the first storage chamber 401 through the return channel 403. Lowering the center of gravity makes the plumb bob more stable during the swing. According to the principle of gravity, the lower the center of gravity of an object, the better its stability. When the center of gravity of the plumb bob is lowered, it is less likely to deviate from its vertical direction when it is swayed by external forces, and it can return to a stable vertical state more quickly, thereby improving the accuracy of the measurement.

[0038] Specifically, the working process or principle of this verticality measuring device for urban planning is as follows: The operator moves the entire device to the location where the measurement is to be performed. Then, the main rod 201 is rotated to ensure close contact between the main rod 201 and the wall to be measured. When the verticality of the wall needs to be measured, the operator rotates the handle 204, causing the roller 203 to rotate and releasing the string 205 on the surface of the roller 203. In this situation, the plumb bob 206 remains perpendicular to the horizontal plane under the influence of gravity. Because the string 205 remains perpendicular to the horizontal plane under the action of the plumb bob 206, when the wall to be measured tilts, the angle between the second side plate 207 and the string 205 changes, thus the verticality of the string... The intersection point between rope 205 and the second side plate 207 will also change. Under the action of the plumb bob 206, the change in the intersection point of rope 205 will cause the position of threaded block 211 inside the sliding groove 208 to change. Therefore, it can drive threaded block 211 to slide on the surface of the first threaded rod 210. When threaded block 211 moves, it will drive the first threaded rod 210 to rotate. The rotating first threaded rod 210 can drive the second gear 214 to rotate. The rotating second gear 214 can drive the first gear 213 to rotate. The rotating first gear 213 can drive the pointer 216 to rotate. The staff can judge the tilt angle of the wall to be measured by observing the position of pointer 216 on the indicator plate 215.

[0039] When the first threaded rod 210 rotates, it drives the left second gear 214 to rotate. The rotating left second gear 214 drives the second bevel gear 305 to rotate, and the rotation of the second bevel gear 305 drives the first bevel gear 304 to rotate. The second pulley 311 is fixedly connected to the first bevel gear 304. When the first bevel gear 304 rotates, it drives the second pulley 311 to rotate. A spray can 328 is fixedly installed on the top of the second mounting plate 312. A spray nozzle 329 is connected to the top of the spray can 328 via a hose. The rotation of the second pulley 311 drives the first pulley 310 to rotate, which in turn drives the first take-up roller 309 to rotate, which in turn drives the perforated marking ruler 315 to move up and down. The perforated marking ruler 315 has angle data engraved on its surface. After the worker observes that the plumb bob 206 is stable, they press the button on the handle to start the spray can 328, spraying paint through the hose and nozzle 329. The paint is sprayed onto the surface of the marking sticker 318 via the perforated marking ruler 315. When the plumb bob... After 206 stabilizes, the operator starts motor 319. Motor 319 drives the third pulley 320 to rotate, which in turn drives the fourth pulley 321. The rotation of the fourth pulley 321 causes the second take-up roller 317 to rotate. The second take-up roller 317 is connected to the second unwind roller 316 via a pulley set. The rotation of the second take-up roller 317 drives the second unwind roller 316 to rotate, which in turn causes the marking sticker 318 to move upward. When the second unwind roller 316 rotates, it drives the rotating shaft 322 to rotate. 322 can drive the rotating disk 323 to rotate, which in turn drives the eccentric plate 327 to rotate eccentrically, which in turn causes the reciprocating rod 325 to reciprocate inside the bracket 324, thereby driving the push plate 326 to reciprocate. The push plate 326 can squeeze and cut the marking sticker 318 so that the marking sticker 318 can be pasted on the wall to be tested. Before the marking sticker 318 moves upward, the nozzle 329 has already sprayed the marking sticker 318. Therefore, the marking mechanism 3 can record the measured data on the wall to be tested through the marking sticker 318, which is beneficial for comparison after the maintenance is completed.

[0040] When the plumb bob 206 is used for verticality measurement, if there is a strong wind, the plumb bob 206 will sway under the influence of the wind. The swaying of the plumb bob 206 causes the two balls 410 to roll inside the rolling groove 409. The rolling of the balls 410 can strike the fan blade 407, causing the fan blade 407 to rotate. This can drive the drive shaft 405 to rotate. The rotating drive shaft 405 can drive the baffle 406 to rotate, exposing the through groove 404. The fluid in the upper first storage chamber 401 flows into the lower second storage chamber 402 through the through groove 404, which lowers the center of gravity of the plumb bob 206 and reduces the amplitude of swaying. After use, the staff will invert the plumb bob 206, and the fluid in the second storage chamber 402 will flow back into the first storage chamber 401 through the return groove 403.
