DETAILED DESCRIPTION

[0020] like Figure 1-Figure 12 As shown, a building load detection device and detection method, comprising two cantilevers 5 arranged opposite to each other, a box body 3 is slidably arranged on one side of the two cantilevers 5 opposite to each other, and the box body 3 is elastically connected to the cantilever 5, so that the box body 3 can slide along the length direction of the cantilever 5, and a convex strip 11 is fixedly arranged on the inner side surface of the cantilever 5, and the convex strip 11 is used to place a load-bearing member 4, and the top surface of the convex strip 11 is flush with the bottom surface of the inner cavity of the box body 3, so that the load-bearing member 4 can slide from the convex strip 11 to the inside of the box body 3; A carrying plate 29 for supporting the load-bearing member 4 is provided at the end position of the cantilever 5, and a table 1 is provided at one end of the cantilever 5 away from the carrying plate 29. In actual use, the cantilever 5 is driven to rotate. During the rotation of the cantilever 5, the load-bearing member 4 can be lifted by the convex strip 11 and slide down along the convex strip 11 into the box body 3. With the rotation of the cantilever 5, the load-bearing member 4 to be detected can be flipped to the table 1. Of course, in actual application, a groove can be opened on the top of the table 1, and a workbench 30 is installed at the groove. Both sides of the top of the workbench 30 are set to the first inclined surface 3001. The workbench 30 can move in the vertical direction relative to the table 1. The workbench 3 0 and the inner bottom surface of the groove are provided with a pressure sensor. Of course, the pressure sensor can be connected to an external display. A hydraulic cylinder is provided above the workbench 30. A pressure block 31 is fixedly provided at the telescopic end of the hydraulic cylinder. When the cantilever 5 is flipped to a horizontal state in the direction close to the workbench 30, the load-bearing member 4 can fall onto the workbench 30. At this time, the pressure block 31 is driven downward by the hydraulic cylinder to squeeze the load-bearing member 4. The pressure value can be detected by the pressure sensor. After the detection is completed, the cantilever 5 rotates in the opposite direction to drive the load-bearing member 4 to move away from the workbench 30. The specific structure and working principle of the pressure sensor are mature technical means and will not be elaborated here.

[0021] like Figure 1-Figure 6 , Figure 8-Figure 11As shown, a slide groove 14 is provided on the cantilever 5, and the box body 3 is slidably arranged in the slide groove 14, and two limit plates 8 are fixedly arranged on the outer surface of the cantilever 5, and the two limit plates 8 are distributed on the upper and lower sides of the box body 3. Specifically, an inclined groove 20 is provided on the side of the limit plate 8 close to the box body 3, and the inclined groove 20 is inclined, and a limit column 17 that slidably cooperates with the inclined groove 20 is elastically provided on the box body 3. Specifically, when the cantilever 5 is rotated upward to a vertical state, the box body 3 can slide downward along the slide groove 14, and the limit column 17 slides downward along the inclined groove 20. In this process, the two box bodies 3 can gradually move away from each other, thereby exposing the workpiece to be detected. The limit plate 8 is also provided with a horizontal groove 21 connected to the inclined groove 20, and the horizontal groove 21 is distributed at the two end positions of the inclined groove 20, and the horizontal groove 21 is parallel to the length direction of the cantilever 5; During specific use, when the cantilever 5 rotates, the convex strip 11 can be used to lift the load-bearing piece 4, so that the load-bearing piece 4 gradually slides into the two box bodies 3, and as the cantilever 5 gradually rotates to a vertical state, the box body 3 and the load-bearing piece 4 will slide downward along the cantilever 5, and the cooperation between the limit column 17 and the inclined groove 20 allows the box body 3 to move outward relative to the cantilever 5 during the downward sliding process, thereby exposing the load-bearing piece 4, and when the cantilever 5 is flipped to the side of the workbench 30, the load-bearing piece 4 can be exposed on the workbench 30, which is conducive to its inspection.

[0022] The cantilever 5 is provided with a traction assembly matched with the limit column 17. When the load-bearing member 4 is broken during the detection process, the traction assembly will be squeezed, and the traction assembly can form a certain pulling force on the limit column 17, so that the limit column 17 is moved out of the horizontal groove 21, so that the two box bodies 3 can be gradually approached, and the broken stones on the platform 1 can be shoveled up during the process of the two box bodies 3 being attached, so as to prevent the stones from being retained on the platform 1; Furthermore, the opposite side of the two box bodies 3 and the side of the box body 3 close to the load-bearing member 4 are both in an open state, so that the load-bearing member 4 can slide from the convex strip 11 into the box body 3. Figure 2-Figure 4 As shown, a shoveling plate 12 is integrally formed on the top of the box body 3, and the structure of the shoveling plate 12 is as follows: Figure 2 , Figure 4 As shown, specifically, only one side of the scraping plate 12 is connected to the box body 3, and the other three sides are in a free state, so that the scraping plate 12 can be deformed relative to the box body 3. The scraping plate 12 can be made of steel plate to give it a certain toughness. When the cantilever 5 is flipped over the workbench 30, the top surface of the scraping plate 12 is flush with the top of the workbench 30. When the two box bodies 3 are close to each other, the scraping plate 12 can be used to shovel up the gravel on the workbench 30 and store it between the two box bodies 3.

[0023] The traction assembly includes a main magnet 18 disposed on the horizontal surface inside the box body 3 and slidingly matched with the box body 3, and a traction rope 15 is fixedly disposed between the main magnet 18 and the limit column 17, and the traction rope 15 passes through the box body 3 and slides with it; A docking plate 24 is slidably provided on the inner side of the cantilever 5, and a positioning plate 27 is elastically provided on one end of the docking plate 24 close to the box body 3. The positioning plate 27 is inserted into the box body 3, and the positioning plate 27 can slide along the width direction of the cantilever 5 relative to the docking plate 24. Figure 9-11 As shown, a card slot 28 is provided on the side opposite to the positioning plate 27 inside the box body 3, and a card block 22 is fixedly provided at one end of the positioning plate 27 away from the docking plate 24. The card block 22 is slidably arranged in the card slot 28, and the cross-sections of the card block 22 and the card slot 28 are both set to be T-shaped. Figure 4-Figure 6 , Fig.10 As shown, a secondary magnet 32 ​​is fixedly disposed on one side of the positioning plate 27 close to the main magnet 18 , and the opposite sides of the main magnet 18 and the secondary magnet 32 ​​have different magnetic poles.

[0024] In actual use, the load-bearing member 4 is placed on the convex strip 11 and the cantilever 5 is driven to rotate. The cantilever 5 can lift the load-bearing member 4 by using the convex strip 11 during the rotation. As the cantilever 5 rotates, the load-bearing member 4 will slide along the convex strip 11 into the two box bodies 3 and cause the box bodies 3 to slide downward relative to the cantilever 5. Through the cooperation of the limit column 17 and the inclined groove 20, the box body 3 can also move outward relative to the cantilever 5 during the process of sliding downward along the cantilever 5 to expose the load-bearing member 4. When the cantilever 5 is rotated to a vertical position, the load-bearing member 4 can be lifted up by the convex strip 11. When in the upward state, the box body 3 slides to the bottom end of the slide slot 14, and the limit column 17 slides to the horizontal slot 21. When the cantilever 5 flips to the workbench 30 and is in a horizontal state, the load-bearing piece 4 can fall onto the workbench 30. At this time, the shovel plate 12 on the box body 3 is located below the load-bearing piece 4 and is arranged opposite to the first inclined surface 3001 on the workbench 30. The hydraulic cylinder drives the pressure block 31 to move downward to apply pressure to the load-bearing piece 4, and the pressure sensor is used to detect the pressure value. If the load-bearing member 4 is in good condition after the test, the cantilever 5 can be driven to rotate in the opposite direction; If the load-bearing member 4 breaks during the test, the load-bearing member 4 will push the positioning plate 27 away from the load-bearing member 4 after breaking, so that the secondary magnet 32 ​​on the positioning plate 27 is aligned with the main magnet 18 on the box body 3. The suction force between the main magnet 18 and the secondary magnet 32 ​​can be used to tighten the traction rope 15, so that the traction rope 15 can apply pressure to the limit column 17, which is conducive to driving one end of the limit column 17 to move out of the horizontal groove 21. When the limit column 17 is disconnected from the horizontal groove 21, the box body 3 will rebound. The two boxes 3 are reset, so that the two box bodies 3 gradually approach each other. During this process, the shovel plate 12 can be used to shovel the gravel on the workbench 30 and store it between the two box bodies 3, so as to avoid gravel remaining on the workbench 30. Then, the cantilever 5 is driven to rotate in the opposite direction, which is conducive to taking the gravel away from the workbench 30. As the cantilever 5 rotates in the opposite direction to a vertical downward state, the gravel will fall from between the two box bodies 3, and the box body 3 will also return to the initial position, so that the limit column 17 can return to the horizontal groove 21 for the next use.

[0025] To summarize, this device can, through the two box bodies 3, on the one hand, flip the load-bearing piece 4, which is conducive to placing the load-bearing piece 4 on the workbench 30 for testing, and after the testing is completed, it can also be quickly removed from the workbench 30 using the box body 3. On the other hand, when the load-bearing piece 4 is broken during the test, the two box bodies 3 can be close to each other, so that the scraping plate 12 set on the box body 3 can clean up the gravel on the workbench 30, avoiding the gravel from being retained on the workbench 30, which is conducive to the normal progress of the next test.

[0026] like Figure 1-Figure 3 As shown, in order to drive the cantilever 5 to rotate, a vertical plate 10 is provided on the outer side of the cantilever 5, and a driving shaft 2 is provided between the two cantilevers 5. The driving shaft 2 passes through the cantilever 5 and is fixedly connected thereto. The driving shaft 2 passes through the vertical plate 10 and rotates with it. One end of the driving shaft 2 passing through the vertical plate 10 is fixedly connected to a driven gear 9, and a driving gear is meshed on the outer side of the driven gear 9. Furthermore, a motor is fixedly mounted on the vertical plate 10 via a base, and an output shaft of the motor is connected to a driving gear to drive the cantilever 5 to rotate.

[0027] The bottom of the bearing plate 29 and the platform 1 are fixedly provided with supporting legs, one side of the platform 1 is provided with a fixing frame, and the hydraulic cylinder is installed on the fixing frame.

[0028] A U-shaped slide plate 6 is arranged between the two limit plates 8 on the same side, and the slide plate 6 is located on the outer side of the limit plate 8 and can slide relative to the limit plate 8. Bumps are fixedly arranged on the outer side of the limit plate 8 and near the two ends, and a guide shaft 13 is fixedly arranged between the two bumps. The guide shaft 13 passes through the slide plate 6 and slides with it. A limit rod 7 is fixedly arranged on the outer side of the box body 3, and the limit rod 7 passes through the slide plate 6 and slides with it. A compression spring 16 is sleeved on the outer side of the limit rod 7, and the two ends of the compression spring 16 are fixedly connected to the slide plate 6 and the box body 3 respectively.

[0029] In actual use, when the box body 3 slides downward relative to the cantilever 5, the cooperation between the limit column 17 and the inclined groove 20 enables the box body 3 to slide outward relative to the cantilever 5. During this process, the box body 3 can drive the slide plate 6 to move synchronously, and the box body 3 will compress the compression spring 16; When the limiting column 17 is separated from the horizontal groove 21 , the compression spring 16 can push the box body 3 , thereby causing the two box bodies 3 to gradually approach each other.

[0030] like Figure 1-Figure 5 As shown, a first slot is provided on the top and bottom surfaces of the box body 3, and the main magnet 18 is slidably disposed in the first slot, and a stopper is fixedly disposed near the end of the first slot to prevent the main magnet 18 from being separated from the box body 3; Furthermore, an air hole 19 connected to the first slot can be opened on the box body 3, and the main magnet 18 can be sealed and connected to the first slot. In actual use, when the cantilever 5 rotates to a vertically upward state so that the box body 3 slides downward to one end of the slide slot 14, the main magnet 18 will pass over the positioning plate 27 and be staggered with the auxiliary magnet 32. During this process, the main magnet 18 and the auxiliary magnet 32 ​​overlap with each other for a short time, and the air hole 19 is set, so that the main magnet 18 moves slowly in the first slot. Therefore, in the process of the box body 3 falling along the slide slot 14, the limit column 17 will not be disconnected from the inclined slot 20 or the horizontal slot 21. When the load-bearing member 4 is broken, by maintaining the stability of the pressure block 31, the load-bearing member 4 can push the positioning plate 27 and keep the positioning plate 27 stable for a certain period of time, so that the main magnet 18 and the auxiliary magnet 32 ​​have enough time to cooperate.

[0031] like Figure 6 As shown, the top and bottom of the box body 3 are both provided with a second slot, the limiting column 17 is slidably set in the second slot, and a first spring is fixedly set between the inner end surface of the second slot and the limiting column 17, so as to realize the elastic connection between the limiting column 17 and the box body 3.

[0032] like Figure 7-Figure 9As shown, in order for the docking plate 24 to be able to stably cooperate with the cantilever 5, a square groove is opened on the inner side surface of the cantilever 5, and the docking plate 24 is slidably set in the square groove, and a T-shaped groove is opened on the inner end surface of the square groove, and a connecting strip 23 is fixedly set on one side surface of the docking plate 24 close to the T-shaped groove. The cross-section of the connecting strip 23 is set to be T-shaped, and the connecting strip 23 is slidably set in the T-shaped groove, so as to avoid the docking plate 24 and the cantilever 5 from detaching.

[0033] A storage groove is provided on one side of the docking plate 24 close to the positioning plate 27, and a protrusion 26 that slides with the storage groove is fixedly provided on the positioning plate 27. A connecting rod 25 is fixedly provided in the storage groove, and the connecting rod 25 passes through the protrusion 26 and slides with it. A second spring is sleeved on the outside of the connecting rod 25, and the second spring is located between the protrusion 26 and the inner end face of the storage groove, so that the positioning plate 27 can move along the width direction of the cantilever 5 relative to the docking plate 24.
