Description

Technical Field

[0001] The present invention relates to the technical field of building component detection devices, and particularly relates to a building load detection device and a detection method. Background Art

[0002] Mortar strength detection usually includes steps such as specimen preparation, curing, and pressure testing. Common equipment includes a pressure testing machine.

[0003] Chinese Patent CN219830635U discloses a building mortar strength detection device. Through the combined action of the detection device and the protection device, it not only avoids the deviation of the detection result caused by the sliding of the sample during the detection process, but also avoids the phenomenon of mortar fragments splashing and causing injury to the staff.

[0004] The above device performs a pressure test on the mortar block through a hydraulic device. However, when the mortar block breaks during the test, the staff needs to clean up the broken stones to avoid affecting the next test, and the overall operation is rather inconvenient. In summary, the above device still has room for improvement.

[0005] Therefore, it is necessary to provide a building load detection device and a detection method to solve the above technical problems. Summary of the Invention

[0006] The purpose of the present invention is to provide a building load detection device and a detection method to solve the problem that in the existing device, a pressure test is performed on the mortar block through a hydraulic device, but when the mortar block breaks during the test, the staff needs to clean up the broken stones to avoid affecting the next test, and the overall operation is rather inconvenient as mentioned in the above background art.

[0007] Based on the above idea, the present invention provides the following technical solution: A building load detection device includes two cantilevers arranged oppositely. A box body is slidably arranged inside the cantilevers. A rib for placing a load-bearing member is fixedly arranged on the inner side surface of the cantilever. A platen is arranged at one end of the cantilever, and a workbench is installed on the top of the platen. A pressure sensor is installed between the workbench and the platen. Two limiting plates are fixedly arranged on the outer side surface of the cantilever, and the two limiting plates are distributed on the upper and lower sides of the box body. An inclined groove is formed on the surface of the limiting plate close to the box body. A limiting column is elastically arranged on the box body and is slidably matched with the inclined groove.

[0008] A traction assembly is arranged on the cantilever and is matched with the limiting column. When the load-bearing member breaks during the detection, it will squeeze the traction assembly. When the traction assembly coincides with the limiting column and remains stable, the traction assembly can cause the limiting column to disengage from the limiting plate, making the two box bodies gradually approach each other.

[0009] As a further solution of the present invention: a hydraulic cylinder is provided above the workbench, and a pressing block is fixedly arranged at the telescopic end of the hydraulic cylinder.

[0010] As a further solution of the present invention: one side surface of the two boxes facing each other and the side of the box close to the load-bearing member are both in an open state, and a shoveling plate is integrally formed at the top of the box. When the cantilever rotates to above the workbench, the top surface of the shoveling plate is aligned with the top of the workbench. When the two boxes approach each other, the shoveling plate can shovel up the crushed stones on the workbench and store them between the two boxes.

[0011] As a further solution of the present invention: the traction assembly includes a main magnet arranged on the horizontal plane inside the box and slidably matched with the box. A traction rope is fixedly arranged between the main magnet and the limiting column. A docking plate is slidably arranged on the inner side surface of the cantilever. A positioning plate is elastically arranged at one end of the docking plate close to the box. The positioning plate can slide along the width direction of the cantilever relative to the docking plate. A clamping groove is formed on the side surface of the box opposite to the positioning plate. A clamping block is fixedly arranged at one end of the positioning plate away from the docking plate. The clamping block is slidably arranged in the clamping groove, and the cross sections of the clamping block and the clamping groove are both arranged in a T shape. A secondary magnet is fixedly arranged on one side of the positioning plate close to the main magnet. The opposite surfaces of the main magnet and the secondary magnet have different magnetic poles.

[0012] As a further solution of the present invention: a square groove is formed on the inner side surface of the cantilever, and the docking plate is slidably arranged in the square groove.

[0013] As a further solution of the present invention: a T-shaped groove is formed on the inner end surface of the square groove. A connecting strip is fixedly arranged on one side surface of the docking plate close to the T-shaped groove. The cross section of the connecting strip is arranged in a T shape, and the connecting strip is slidably arranged in the T-shaped groove.

[0014] As a further solution of the present invention: a sliding groove is formed on the cantilever, and the box is slidably arranged in the sliding groove.

[0015] As a further solution of the present invention: both sides of the top of the workbench are arranged as first inclined surfaces.

[0016] As a further solution of the present invention: the top surface of the convex strip is flush with the bottom surface of the inner cavity of the box.

[0017] A method for detecting using the above building load detection device includes the following steps: placing the load-bearing member on the convex strip, and then driving the cantilever to rotate. During the rotation of the cantilever, the load-bearing member can fall into the box; when the cantilever rotates to the workbench, the load-bearing member can be stably placed on the workbench, and the boxes on both sides of the load-bearing member can move away from each other, so that the load-bearing member can be exposed; testing the load-bearing member with the pressing block connected to one end of the hydraulic cylinder.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: Through the two box bodies provided, on the one hand, the load-bearing member can be flipped, which is beneficial for placing the load-bearing member on the workbench for inspection. And after the inspection is completed, it can also be quickly removed from the workbench by using the box body. On the other hand, when the load-bearing member breaks during the test, the two box bodies can approach each other, so that the gravel on the workbench can be cleaned by the shoveling plates provided on the box bodies, avoiding the retention of gravel on the workbench and facilitating the normal progress of the next test.

Detailed implementation manners

[0033] As Figures 1 - 12 shown, a building load detection device and a detection method include two cantilevers 5 arranged oppositely. On the opposite sides of the two cantilevers 5, box bodies 3 are slidably arranged, and the box bodies 3 are elastically connected to the cantilevers 5, so that the box bodies 3 can slide along the length direction of the cantilevers 5. Ribs 11 are fixedly arranged on the inner side surfaces of the cantilevers 5. The ribs 11 are used for placing load-bearing members 4, and the top surfaces of the ribs 11 are flush with the inner cavity bottom surfaces of the box bodies 3, so that the load-bearing members 4 can slide from the ribs 11 into the box bodies 3.

[0034] A bearing plate 29 for supporting the load-bearing member 4 is arranged at the end position of the cantilever 5. A platen 1 is arranged at one end of the cantilever 5 far from the bearing plate 29. During actual use, when the cantilever 5 rotates, during the rotation of the cantilever 5, the load-bearing member 4 can be lifted by the rib 11 and slide down along the rib 11 into the box body 3. As the cantilever 5 rotates, the load-bearing member 4 to be detected can be flipped to the platen 1. Of course, during actual application, a groove can be opened at the top of the platen 1, and a workbench 30 is installed in the groove. Both sides of the top of the workbench 30 are arranged as first inclined surfaces 3001. The workbench 30 can move in the vertical direction relative to the platen 1. A pressure sensor is installed between the workbench 30 and the inner bottom surface of the groove. Of course, the pressure sensor can be connected to an external display. A hydraulic cylinder is arranged above the workbench 30. A pressing block 31 is fixedly arranged at the telescopic end of the hydraulic cylinder. When the cantilever 5 rotates towards the direction close to the workbench 30 to a horizontal state, the load-bearing member 4 can fall onto the workbench 30. At this time, the hydraulic cylinder drives the pressing block 31 to move downward to squeeze the load-bearing member 4, and the pressure value can be detected by the pressure sensor. After the detection is completed, the cantilever 5 rotates in the reverse 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.

[0035] As Figures 1 - 6 、 Figures 8 - 11As shown in the figure, a chute 14 is formed on the cantilever 5, and the box body 3 is slidably arranged in the chute 14. Two limit plates 8 are fixedly arranged on the outer side 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 formed on the surface of the limit plate 8 close to the box body 3. The inclined groove 20 is inclined, and a limit post 17 which is elastically arranged on the box body 3 and slidably matched with the inclined groove 20 is provided. Specifically, when the cantilever 5 rotates upward to the vertical state, the box body 3 can slide downward along the chute 14, and the limit post 17 slides downward along the inclined groove 20. During this process, the two box bodies 3 can gradually move away from each other, so as to expose the workpiece to be detected. A horizontal groove 21 communicating with the inclined groove 20 is further formed on the limit plate 8. The horizontal groove 21 is distributed at both ends of the inclined groove 20 and is parallel to the length direction of the cantilever 5;

[0036] During specific use, when the cantilever 5 rotates, the load-bearing member 4 can be lifted by the convex strip 11, so that the load-bearing member 4 gradually slides into the two box bodies 3. As the cantilever 5 gradually rotates to the vertical state, the box body 3 and the load-bearing member 4 will slide downward along the cantilever 5. Through the cooperation of the limit post 17 and the inclined groove 20, the box body 3 can move outward relative to the cantilever 5 during the downward sliding process, so as to expose the load-bearing member 4. When the cantilever 5 is flipped to one side of the workbench 30, the load-bearing member 4 can be exposed on the workbench 30, which is beneficial to the detection thereof.

[0037] A traction assembly matched with the limit post 17 is arranged on the cantilever 5. When the load-bearing member 4 is broken during the detection process, the traction assembly will be extruded. The traction assembly can form a certain pulling force on the limit post 17, so that the limit post 17 moves out of the horizontal groove 21, so that the two box bodies 3 can gradually approach each other. During the process of the two box bodies 3 being attached to each other, the broken stones on the table board 1 can be shoveled up, so as to prevent the stones from staying on the table board 1;

[0038] Further, the opposite side surfaces 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. As Figures 2 - 4 shown, a material shoveling plate 12 is integrally formed on the top of the box body 3. The structure of the material shoveling plate 12 is Figure 2 、 Figure 4 shown. Specifically, only one side of the material shoveling plate 12 is connected to the box body 3, and the other three sides are all in a free state, so that the material shoveling plate 12 can deform relative to the box body 3. The material shoveling plate 12 can be made of steel plate to make it have a certain toughness. When the cantilever 5 is flipped above the workbench 30, the top surface of the material shoveling plate 12 is flush with the top of the workbench 30. When the two box bodies 3 approach each other, the broken stones on the workbench 30 can be shoveled up by the material shoveling plate 12 and stored between the two box bodies 3.

[0039] The above traction assembly includes a main magnet 18 disposed on the horizontal plane inside the box body 3 and slidably engaged with the box body 3. A traction rope 15 is fixedly arranged between the main magnet 18 and the limit post 17. The traction rope 15 passes through the box body 3 and is slidably engaged with it;

[0040] A docking plate 24 is slidably arranged on the inner side surface of the cantilever 5. One end of the docking plate 24 close to the box body 3 is elastically provided with a positioning plate 27. The positioning plate 27 is inserted into the box body 3. The positioning plate 27 can slide along the width direction of the cantilever 5 relative to the docking plate 24. The combination Figures 9 - 11 As shown, a card slot 28 is formed on the side surface of the box body 3 opposite to the positioning plate 27. One end of the positioning plate 27 away from the docking plate 24 is fixedly provided with a card block 22. The card block 22 is slidably arranged in the card slot 28. The cross sections of the card block 22 and the card slot 28 are both arranged in a T shape. Refer to Figures 4 - 6 、 Figure 10 As shown, a secondary magnet 32 is fixedly arranged on the side of the positioning plate 27 close to the main magnet 18. The opposite sides of the main magnet 18 and the secondary magnet 32 have different magnetic poles.

[0041] During actual use, the load-bearing member 4 is placed on the convex strip 11 and 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. 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 body 3 to slide downward relative to the cantilever 5. Through the cooperation of the limit post 17 and the inclined groove 20, when the box body 3 slides downward along the cantilever 5, it can also move outward relative to the cantilever 5 to expose the load-bearing member 4. When the cantilever 5 rotates to the vertically upward state, the box body 3 slides to the bottom position of the sliding groove 14, and the limit post 17 slides to the horizontal groove 21. When the cantilever 5 flips to the workbench 30 and is in a horizontal state, the load-bearing member 4 can fall onto the workbench 30. At this time, the material shoveling plate 12 on the box body 3 is located below the load-bearing member 4 and is arranged opposite to the first inclined surface 3001 on the workbench 30. The hydraulic cylinder drives the pressing block 31 to move downward to press the load-bearing member 4, and the pressure sensor can be used to detect the pressure value;

[0042] If the load-bearing member 4 is in a good state after testing, the cantilever 5 can be driven to rotate in the reverse direction;

[0043] If the load-bearing member 4 breaks during the test, after the load-bearing member 4 breaks, it will push the positioning plate 27 away from the load-bearing member 4, 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 as to apply pressure to the limit post 17 through the traction rope 15, which is beneficial to drive one end of the limit post 17 to move out of the horizontal groove 21. When the limit post 17 is disconnected from the horizontal groove 21, the box body 3 will rebound and reset, so that the two box bodies 3 gradually approach each other. During this process, the material shoveling plate 12 can be used to shovel up the crushed stones on the workbench 30 and store them between the two box bodies 3, so as to avoid leaving crushed stones on the workbench 30. Then drive the cantilever 5 to rotate in the reverse direction, which is beneficial to take away the crushed stones from the workbench 30. As the cantilever 5 rotates in the reverse direction to the vertically downward state, the crushed stones 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 post 17 can return to the horizontal groove 21 again for the next use.

[0044] In summary, through the two box bodies 3 provided in this device, on the one hand, it can flip the load-bearing member 4, which is beneficial to place the load-bearing member 4 on the workbench 30 for inspection, and after the inspection is completed, the box body 3 can also be used to quickly remove it from the workbench 30. On the other hand, when the load-bearing member 4 breaks during the test, the two box bodies 3 can approach each other, so that the material shoveling plate 12 provided on the box body 3 can clean the crushed stones on the workbench 30, avoiding the retention of crushed stones on the workbench 30, which is beneficial to the normal progress of the next test.

[0045] As Figures 1 - 3 shown, in order to drive the cantilever 5 to rotate, a vertical plate 10 is provided on the outside of the cantilever 5, and a drive shaft 2 is provided between the two cantilevers 5. The drive shaft 2 passes through the cantilever 5 and is fixedly connected thereto. The drive shaft 2 passes through the vertical plate 10 and is rotationally matched therewith. One end of the drive shaft 2 passing through the vertical plate 10 is fixedly connected with a driven gear 9, and a driving gear is engaged with the outside of the driven gear 9;

[0046] Further, a motor is fixedly installed on the vertical plate 10 through a base, and the output shaft of the motor is connected to the driving gear to drive the cantilever 5 to rotate.

[0047] Support legs are fixedly provided at the bottoms of the bearing plate 29 and the table plate 1. A fixing frame is provided on one side of the table plate 1, and the hydraulic cylinder is installed on the fixing frame.

[0048] A U-shaped sliding plate 6 is arranged between two limiting plates 8 on the same side. The sliding plate 6 is located outside the limiting plates 8 and can slide relative to the limiting plates 8. Protrusions are fixedly arranged at positions on the outer sides of the limiting plates 8 close to both ends. A guiding shaft 13 is fixedly arranged between the two protrusions. The guiding shaft 13 passes through the sliding plate 6 and is in sliding fit with it. A limiting rod 7 is fixedly arranged on the outer side surface of the box body 3. The limiting rod 7 passes through the sliding plate 6 and is in sliding fit with it. A compression spring 16 is sleeved on the outer side of the limiting rod 7. Two ends of the compression spring 16 are fixedly connected to the sliding plate 6 and the box body 3 respectively.

[0049] During actual use, when the box body 3 slides downward relative to the cantilever 5, the cooperation between the limiting 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 sliding plate 6 to move synchronously, and the box body 3 will compress the compression spring 16.

[0050] When the limiting column 17 is separated from the horizontal groove 21, the compression spring 16 can push the box body 3, thereby promoting the two box bodies 3 to gradually approach each other.

[0051] As Figures 1 - 5 shown, first slots are opened on both the inner top surface and the bottom surface of the box body 3. The main magnet 18 is slidably arranged in the first slots. A stop block is fixedly arranged at a position in the first slots close to the end, so as to prevent the main magnet 18 from detaching from the box body 3.

[0052] Furthermore, air holes 19 communicating with the first slots can be opened on the box body 3. The main magnet 18 can be hermetically connected to the first slots. During actual use, when the cantilever 5 rotates to the vertically upward state and the box body 3 slides downward to one end of the sliding groove 14, the main magnet 18 will cross over the positioning plate 27 and be staggered from the secondary magnet 32. During this process, the overlapping time of the main magnet 18 and the secondary magnet 32 is relatively short. By providing the air holes 19, the movement of the main magnet 18 in the first slots is relatively slow. Therefore, during the process of the box body 3 falling along the sliding groove 14, the limiting column 17 will not be disconnected from the inclined groove 20 or the horizontal groove 21. When the load-bearing member 4 is broken, by keeping the pressing block 31 stable, 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 secondary magnet 32 have enough time to cooperate.

[0053] As Figure 6 shown, second slots are opened at both the top and the bottom of the box body 3. The limiting column 17 is slidably arranged in the second slots. A first spring is fixedly arranged between the inner end face of the second slots and the limiting column 17, so as to realize the elastic connection between the limiting column 17 and the box body 3.

[0054] As Figures 7 - 9As shown in the figure, in order for the docking plate 24 to be stably fitted with the cantilever 5, a square groove is formed on the inner side surface of the cantilever 5, and the docking plate 24 is slidably arranged in the square groove. A T-shaped groove is formed on the inner end surface of the square groove. A connecting bar 23 is fixedly arranged on one side surface of the docking plate 24 close to the T-shaped groove. The cross-section of the connecting bar 23 is T-shaped, and the connecting bar 23 is slidably arranged in the T-shaped groove, so as to prevent the separation between the docking plate 24 and the cantilever 5.

[0055] A storage groove is formed on one side of the docking plate 24 close to the positioning plate 27. A protrusion 26 slidably fitted with the storage groove is fixedly arranged on the positioning plate 27. A connecting rod 25 is fixedly arranged in the storage groove, and the connecting rod 25 passes through the protrusion 26 and is slidably fitted with it. A second spring is sleeved outside the connecting rod 25. The second spring is located between the protrusion 26 and the inner end surface of the storage groove, so that the positioning plate 27 can move relative to the docking plate 24 along the width direction of the cantilever 5.
