Description

Technical Field

[0001] The present invention relates to the technical field of stress monitoring, and in particular to an assembled stress monitoring device and an automatic stress monitoring method. Background Art

[0002] During the construction process of construction projects, the connection and assembly accuracy requirements between different components are relatively high. Through a stress monitoring device, the stress changes of components during the assembly process can be monitored in real time, problems that may occur during the assembly process can be discovered and solved in a timely manner, and the construction quality can be ensured. For example, in an assembled steel structure building, the stress conditions at the connection nodes of components such as steel beams and steel columns are crucial for the overall stability of the structure, and precise stress monitoring is required.

[0003] Traditional stress monitoring methods usually require a large amount of wiring and sensor installation work at the construction site. The construction process is complex and time-consuming. For construction methods with a short construction period and high requirements for construction efficiency, traditional methods are difficult to meet the needs. For example, in some large construction projects, if traditional stress monitoring methods are used, a large amount of time may be occupied by the installation and debugging of monitoring equipment, affecting the construction progress.

[0020] An automatic stress monitoring method is applicable to the above-mentioned assembled stress monitoring device, and the steps are as follows:

[0021] S1: First, the staff installs the entire device at the place where stress monitoring is required. When the top of the top plate is subjected to stress extrusion from the top, it will cause the cushion plate to move downward, thereby squeezing the first spring and also driving the first threaded rod to move downward;

[0022] S2: As the stress changes, the third gear continues to rotate, thereby driving the threaded sleeve to rotate. The rotation of the threaded sleeve can drive the first pulley to rotate, and the rotation of the first pulley can drive the second pulley to rotate, thereby causing the bidirectional threaded rod to rotate, thereby driving the protective plate to move and enabling the protective plate to unfold;

[0023] S3: When the protective plate unfolds outward, it can cause the first partition plate to move upward inside the water tank, so that the water inside the water tank enters the display box through the water pipe. The staff can judge the stress situation at the top by observing the water level height inside the display box;

[0024] S4: When the guard plate is deployed outward, the second tooth plate can be driven to move, so that the lever can be rotated, and the rotating lever can rotate the blocking rod and the rotating plate, so that the reciprocating rod can slide upward, and the upward sliding of the reciprocating rod can drive the piston plate to slide upward, and the upward sliding of the piston plate can compress the second spring;

[0025] S5: When the lever drives the stop lever to rotate to a certain angle, no force is generated between the lever and the stop lever, and the second spring returns to its original state under the action of the elastic force, causing the hammer head to fall downward at a high speed. The downward fall of the hammer head can hammer the metal plate, causing the metal plate to make a sound, thereby alerting the staff.

[0026] The present invention provides an assembled stress monitoring device, which has the following beneficial effects:

[0027] 1. Through the setting of monitoring mechanism, the stress on the top plate can be monitored, and the protective plate can be moved as the stress changes. In construction projects, stress changes may cause objects to fall. The protective plate can provide a barrier inside the house for objects falling from the top to prevent equipment from being damaged due to collision.

[0028] 2. Through the setting of the observation mechanism, the staff can judge the magnitude of stress by displaying the water height inside the tank. The monitoring of water level changes inside the tank is less affected by external factors such as electromagnetic interference. Unlike the electrical stress monitoring method, the water level change is mainly based on the physical properties of water, such as volume change, thereby ensuring the reliability of stress monitoring.

[0029] 3. Through the setting of early warning mechanism, once the stress reaches the dangerous threshold, the stress monitoring device can issue a sound warning. The loud alarm can immediately attract the attention of on-site personnel. Even if the on-site personnel are focusing on other work tasks or are in a position where they cannot visually observe the display of the monitoring device, such as behind machinery or in a dim basement, the sound warning can effectively convey information.

Specific embodiments

[0042] To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0043] Refer to Figures 1-10, this technical solution provides an assembled stress monitoring device, specifically including legs 1. There are two legs 1. A monitoring mechanism 2 is installed on the side of the two legs 1. The monitoring mechanism 2 includes a mounting plate 201, a top plate 203, a bidirectional threaded rod 204, an observation mechanism 3 and an early warning mechanism 4. The mounting plate 201 is fixedly installed on the side of the leg 1. A third sliding groove 202 is opened at the top of the mounting plate 201. The top plate 203 is fixedly installed on the top of the two legs 1. The bidirectional threaded rod 204 is rotatably installed at the bottom of the mounting plate 201. There are two bidirectional threaded rods 204. A protective plate 205 is threadedly installed on the surface of the bidirectional threaded rod 204. The observation mechanism 3 is installed on the side of the right leg 1. The observation mechanism 3 includes a first gear 301 and a first sliding groove 302. The first gear 301 is rotatably installed on the side of the right leg 1. The first sliding groove 302 is opened on the surface of the right leg 1. The early warning mechanism 4 is installed on the side of the left leg 1. The early warning mechanism 4 includes a second gear 401 and a second sliding groove 402. The second gear 401 is rotatably installed on the side of the left leg 1. The second sliding groove 402 is opened on the surface of the left leg 1. A third gear 206 is rotatably installed at the top of the mounting plate 201. A first threaded barrel 207 is rotatably installed at the top of the third gear 206. A first threaded rod 208 is threadedly installed inside the first threaded barrel 207. A backing plate 209 is fixedly installed at the top of the first threaded rod 208. A first spring 210 is fixedly installed at the bottom of the backing plate 209. There are two first springs 210. The two first springs 210 are arranged between the mounting plate 201 and the backing plate 209. When the top of the top plate 203 is subjected to stress extrusion from the top, it will cause the backing plate 209 to move downward, thereby squeezing the first spring 210. When the stress on the top of the top plate 203 disappears, under the action of the first spring 210, the backing plate 209 will move upward. When the backing plate 209 moves downward, it will drive the first threaded rod 208 to move downward. Because the backing plate 209 is in close contact with the top plate 203, therefore, when the backing plate 209 moves downward, it will cause the first threaded barrel 207 to rotate, while the first threaded rod 208 and the backing plate 209 will not rotate under the action of friction. At the same time, the rotation of the first threaded barrel 207 can drive the third gear 206 to rotate. There are two third sliding grooves 202. A second threaded rod 213 is rotatably installed inside each of the two third sliding grooves 202. The second threaded rod 213 is threadedly connected to the sliding plate 211. A threaded sleeve 217 is threadedly installed on the surface of the second threaded rod 213. The threaded sleeve 217 penetrates to the outside of the third sliding groove 202 and is rotatably connected to the third sliding groove 202. A first pulley 214 is fixedly installed at the end of the threaded sleeve 217. A second pulley 215 is fixedly installed at the end of the bidirectional threaded rod 204. The first pulley 214 and the second pulley 215 are connected by a belt. A second toothed plate 216 is fixedly installed at the bottom of the protective plate 205.When the third gear 206 rotates, the rotating third gear 206 can drive the first toothed plate 212 and the sliding plate 211 inside the third sliding groove 202 to slide. The sliding of the sliding plate 211 can drive the second threaded rod 213 to move inside the threaded sleeve 217, thereby driving the threaded sleeve 217 to rotate. The rotation of the threaded sleeve 217 can drive the first pulley 214 to rotate, and the rotation of the first pulley 214 can drive the second pulley 215 to rotate, thereby causing the bidirectional threaded rod 204 to rotate, and thereby driving the protective plate 205 to move, so that the protective plate 205 can be unfolded. The setting of the protective plate 205 can prevent objects from falling due to changes in the stress of the top building, provide physical protection for the staff at the bottom, and prevent the staff at the bottom from being injured by falling objects from a height.

[0044] Refer to Figures 1-10, this embodiment also proposes that the observation mechanism 3 further includes a third toothed plate 303. The third toothed plate 303 is slidably installed inside the first sliding groove 302. The third toothed plate 303 meshes with the first gear 301, and the first gear 301 meshes with the second toothed plate 216. A cross plate 304 is fixedly installed on the side of the third toothed plate 303. A third threaded rod 305 is fixedly installed at the bottom of the cross plate 304. A side plate 306 is fixedly installed on the side of the leg 1. A second threaded cylinder 307 is rotatably installed inside the side plate 306. The second threaded cylinder 307 is threadedly connected to the third threaded rod 305. A third threaded cylinder 308 is fixedly installed at the bottom of the second threaded cylinder 307. A fourth threaded rod 309 is threadedly installed inside the third threaded cylinder 308. A water tank 310 is fixedly installed on the side of the leg 1. A first partition 311 is slidably installed inside the water tank 310. The top of the first partition 311 is fixedly connected to the fourth threaded rod 309. A display box 312 is fixedly installed at the bottom of the water tank 310. A second partition 313 is slidably installed inside the display box 312. A connecting rod 314 is fixedly installed at the bottom of the first partition 311. The connecting rod 314 penetrates into the display box 312 and is fixedly connected to the second partition 313. A water pipe 315 is fixedly installed on the side of the water tank 310. The water pipe 315 extends into the display box 312. When the protective plate 205 moves, the second toothed plate 216 at the bottom of the protective plate 205 moves. The movement of the second toothed plate 216 can drive the rotation of the first gear 301, and the rotating first gear 301 can make the third toothed plate 303 move up and down inside the first sliding groove 302. The up and down movement of the third toothed plate 303 can drive the cross plate 304 to move up and down, thereby driving the third threaded rod 305 to move up and down. The up and down movement of the third threaded rod 305 can drive the second threaded cylinder 307 to rotate, and the rotating second threaded cylinder 307 can drive the third threaded cylinder 308 to rotate. The rotating third threaded cylinder 308 can make the fourth threaded rod 309 move up and down inside the third threaded cylinder 308. The up and down movement of the fourth threaded rod 309 can drive the inside of the first partition 311 to move up and down. The water inside the water tank 310 is arranged at the top of the first partition 311. When the protective plate 205 is unfolded outward, the first partition 311 can move upward inside the water tank 310, causing the water inside the water tank 310 to enter the display box 312 through the water pipe 315. The display box 312 is made of a transparent material, and scale marks are engraved on the outside of the display box 312. The staff can judge the stress condition at the top by observing the water level height inside the display box 312. When the stress at the top disappears, the first partition 311 moves downward, thereby driving the connecting rod 314 to move downward, and further driving the second partition 313 to move downward. The downward movement of the second partition 313 can squeeze the water inside the display box 312.The water inside the display box 312 re-enters the inside of the water tank 310 through the water pipe 315. At the same time, the water level inside the display box 312 will also drop. Thus, the staff can monitor the stress by observing the change in the water level inside the display box 312.

[0045] Refer to Figures 1-10The present embodiment further proposes that the early warning mechanism 4 further includes an H-shaped plate 403, which is slidably mounted inside the second sliding groove 402, and tooth grooves 404 are provided on both sides of the H-shaped plate 403, the rear tooth groove 404 is meshed with the second gear 401, and the second gear 401 is meshed with the second tooth plate 216, and a fourth gear 405 is rotatably mounted on the side of the left leg 1, and the fourth gear 405 is meshed with the front tooth groove 404, and a fifth gear 406 is rotatably mounted on the other side of the left leg 1, and the fifth gear 406 is fixedly connected to the fourth gear 405, and a sixth gear 407 is rotatably mounted on the other side of the left leg 1, and the sixth gear 407 is meshed with the fifth gear 406, and a rotating shaft 408 is fixedly mounted on the side of the sixth gear 407. , the rotating shaft 408 passes through the side of the left leg 1, a lever 409 is fixedly installed on the surface of the rotating shaft 408, a rotating plate 410 is rotatably installed on the surface of the rotating shaft 408, a blocking rod 411 is fixedly installed on the surface of the rotating plate 410, and a connecting shaft 412 is fixedly installed on the surface of the rotating plate 410, wherein the rotating plane of the rotating plate 410 is higher than the rotating plane of the fourth gear 405, so that the rotating plate 410 can rotate a complete circle without hitting the fourth gear 405, a reciprocating rod 413 is rotatably installed on the end of the connecting shaft 412, a mounting cylinder 414 is fixedly installed on the side of the left leg 1, the reciprocating rod 413 passes through the bottom of the mounting cylinder 414, a piston plate 415 is slidably installed inside the mounting cylinder 414, and the piston plate 41 5 is fixedly connected to the reciprocating rod 413, the surface of the reciprocating rod 413 is sleeved with a second spring 416, the second spring 416 is arranged between the piston plate 415 and the top of the mounting cylinder 414, the bottom of the reciprocating rod 413 is fixedly installed with a hammer head 417, the side of the left leg 1 is fixedly installed with a metal plate 418, the metal plate 418 is arranged just below the hammer head 417, when the protective plate 205 is unfolded outward, the second tooth plate 216 can be driven to move, and then the second gear 401 can be driven to rotate, and then the H-shaped plate 403 slidably installed in the second sliding groove 402 can be driven to move up and down, so as to drive the fourth gear 405 to rotate, and the rotation of the fourth gear 405 can drive the fifth gear 406 to rotate , and the rotation of the fifth gear 406 can drive the sixth gear 407 to rotate, and the rotation of the sixth gear 407 can drive the rotating shaft 408 to rotate, and the rotation of the rotating shaft 408 can drive the lever 409 to rotate, and the rotating lever 409 can make the blocking rod 411 and the rotating plate 410 rotate, and the rotation of the rotating plate 410 can drive the connecting shaft 412 to rotate eccentrically, and the eccentric rotation of the connecting shaft 412 can drive the reciprocating rod 413 to slide upward inside the mounting cylinder 414, and the upward sliding of the reciprocating rod 413 can drive the piston plate 415 to slide upward, and the upward sliding of the piston plate 415 can squeeze the second spring 416, and when the lever 409 drives the blocking rod 411 to rotate to a certain angle,No force acts between the lever 409 and the shift lever 411, and the second spring 416 returns to its original state under the action of elastic force. In this way, the reciprocating rod 413 can be instantaneously restored to its original position, causing the hammer head 417 to fall downward at a very high speed. The downward fall of the hammer head 417 can strike the metal plate 418, causing the metal plate 418 to make a sound to warn the staff.

[0046] Refer to Figures 1-10 In addition, this embodiment also proposes an automated stress monitoring method applicable to the above-mentioned assembled stress monitoring device, and the steps are as follows:

[0047] S1: First, the staff installs the entire device at the location where stress monitoring is required. When the top of the top plate 203 is subjected to stress extrusion from the top, it will cause the backing plate 209 to move downward, thereby squeezing the first spring 210 and also driving the first threaded rod 208 to move downward;

[0048] S2: As the stress changes, the third gear 206 continuously rotates, thereby driving the threaded sleeve 217 to rotate. The rotation of the threaded sleeve 217 can drive the first pulley 214 to rotate, and the rotation of the first pulley 214 can drive the second pulley 215 to rotate, thereby causing the bidirectional threaded rod 204 to rotate, and driving the protective plate 205 to move, so that the protective plate 205 can be unfolded;

[0049] S3: When the protective plate 205 unfolds outward, it can cause the first partition plate 311 to move upward inside the water tank 310, so that the water inside the water tank 310 enters the display box 312 through the water pipe 315. The staff can judge the stress condition at the top by observing the water level height inside the display box 312;

[0050] S4: When the protective plate 205 unfolds outward, it can drive the second toothed plate 216 to move, thereby causing the lever 409 to rotate. The rotating lever 409 can cause the shift lever 411 and the rotating plate 410 to rotate, thereby causing the reciprocating rod 413 to slide upward. The upward sliding of the reciprocating rod 413 can drive the piston plate 415 to slide upward, and the upward sliding of the piston plate 415 can squeeze the second spring 416;

[0051] S5: When the lever 409 rotates the shift lever 411 to a certain angle, no force acts between the lever 409 and the shift lever 411, and the second spring 416 returns to its original state under the action of elastic force, causing the hammer head 417 to fall downward at a very high speed. The downward fall of the hammer head 417 can strike the metal plate 418, causing the metal plate 418 to make a sound to warn the staff.

[0052] Specifically, the working process or principle of this prefabricated stress monitoring device is as follows: First, when the top of the top plate 203 is subjected to stress extrusion from the top, it will cause the backing plate 209 to move downward, thereby squeezing the first spring 210. After the stress on the top of the top plate 203 disappears, under the action of the first spring 210, the backing plate 209 will move upward. When the backing plate 209 moves downward, it will drive the first threaded rod 208 to move downward. Since the backing plate 209 is in close contact with the top plate 203, when the backing plate 209 moves downward, it will cause the first threaded cylinder 207 to rotate. The first threaded rod 208 and the backing plate 209 will not rotate under the action of friction. At the same time, the rotation of the first threaded cylinder 207 can drive the third gear 206 to rotate. When the third gear 206 rotates, the rotating third gear 206 can drive the first toothed plate 212 and the sliding plate 211 inside the third sliding groove 202 to slide. The sliding of the sliding plate 211 can drive the second threaded rod 213 to move inside the threaded sleeve 217, thereby driving the threaded sleeve 217 to rotate. The rotation of the threaded sleeve 217 can drive the first pulley 214 to rotate. The rotation of the first pulley 214 can drive the second pulley 215 to rotate, thereby causing the bidirectional threaded rod 204 to rotate, and then driving the protective plate 205 to move, so that the protective plate 205 can be unfolded. The setting of the protective plate 205 can prevent objects from falling due to changes in the stress of the top building, providing physical protection for the staff at the bottom and avoiding injury to the staff at the bottom from falling objects from a height.

[0053] While the protective plate 205 is moving, the second toothed plate 216 at the bottom of the protective plate 205 moves. The movement of the second toothed plate 216 can drive the rotation of the first gear 301, and the rotating first gear 301 can cause the third toothed plate 303 to move up and down inside the first sliding groove 302. The up and down movement of the third toothed plate 303 can drive the cross plate 304 to move up and down, thereby driving the third threaded rod 305 to move up and down. The up and down movement of the third threaded rod 305 can drive the second threaded cylinder 307 to rotate, and the rotating second threaded cylinder 307 can drive the third threaded cylinder 308 to rotate. The rotating third threaded cylinder 308 can cause the fourth threaded rod 309 to move up and down inside the third threaded cylinder 308. The up and down movement of the fourth threaded rod 309 can drive the inside of the first partition plate 311 to move up and down. The water in the water tank 310 is arranged on top of the first partition plate 311. When the protective plate 205 is unfolded outwards, the first partition plate 311 can move upwards inside the water tank 310, causing the water in the water tank 310 to enter the display box 312 through the water pipe 315. The display box 312 is made of a transparent material, and scale marks are engraved on the outside of the display box 312. The staff can judge the stress situation at the top by observing the water level height inside the display box 312. After the stress at the top disappears, the first partition plate 311 moves downwards, thereby driving the connecting rod 314 to move downwards, and further driving the second partition plate 313 to move downwards. The downward movement of the second partition plate 313 can squeeze the water inside the display box 312, causing the water inside the display box 312 to re-enter the water tank 310 through the water pipe 315. At the same time, the water level inside the display box 312 will also drop. Thus, the staff can monitor the stress by observing the change in the water level inside the display box 312.

[0054] When the protection plate 205 is unfolded outward, the second tooth plate 216 can be driven to move, and then the second gear 401 can be driven to rotate, and then the H-shaped plate 403 slidably installed in the second sliding groove 402 can be driven to move up and down, so as to drive the fourth gear 405 to rotate, and the rotation of the fourth gear 405 can drive the fifth gear 406 to rotate, and the rotation of the fifth gear 406 can drive the sixth gear 407 to rotate, and the rotation of the sixth gear 407 can drive the rotating shaft 408 to rotate, and the rotation of the rotating shaft 408 can drive the lever 409 to rotate, and the rotating lever 409 can make the blocking rod 411 and the rotating plate 410 rotate, and the rotation of the rotating plate 410 can drive the connecting shaft 412 to rotate. The eccentric rotation of the connecting shaft 412 can drive the reciprocating rod 413 to slide upward inside the mounting tube 414, and the upward sliding of the reciprocating rod 413 can drive the piston plate 415 to slide upward, and the upward sliding of the piston plate 415 can squeeze the second spring 416. When the lever 409 drives the baffle rod 411 to rotate to a certain angle, no force is generated between the lever 409 and the baffle rod 411, and the second spring 416 returns to its original state under the action of the elastic force, so that the reciprocating rod 413 can be instantly restored to its original position, and the hammer head 417 can fall downward at a very high speed. The downward falling of the hammer head 417 can hammer the metal plate 418, causing the metal plate 418 to make a sound, thereby warning the staff.
