Description

Technical Field

[0001] The present application relates to the technical field of equipment for quality inspection of precast concrete components, and more specifically, to a strength inspection device and method for precast concrete components. Background Art

[0002] As one of the most critical technical indicators of precast concrete components, the strength of precast concrete components will directly affect the stability and durability of the entire building structure. Therefore, in order to ensure the safety of precast concrete components during use, relevant staff often use precast concrete component strength testing devices to test their strength.

[0003] The document with the prior art publication number CN117147308A provides a device and method for detecting the strength of precast concrete components. The device places the precast concrete components on a rotating frame, which rotates to stack the precast concrete components, thereby simulating the actual use environment of the precast concrete components and achieving accurate detection.

[0004] Although the above-mentioned existing technical solutions can improve the accuracy of strength detection of concrete precast parts to a certain extent, they still have the following defects: in order to ensure the accuracy of the precast part detection results, the staff often need to perform batch detection on the same batch of concrete components. However, when using the above-mentioned technical solutions and most of the detection devices of this type on the market, it is difficult for the staff to achieve continuous detection of precast parts, which not only brings inconvenience to the operator, but also leads to low detection efficiency of precast parts.

[0054] 2. The technical solution of the present application is to set up a guide column, a centering push plate and a rotating mechanism.

[0092] On the basis of the above scheme, the present application provides a precast concrete component strength detection device, wherein the cleaning assembly 5 includes a waste box 501 , a cleaning cover 502 and a receiving shell 503 .

[0093] The waste box 501 is installed below the conveying mechanism 2; the cleaning cover 502 is inserted into one side of the waste box 501; the receiving shell 503 is embedded and fixed on one side of the waste box 501; the receiving shell 503 is arranged in an arc-shaped structure; a plurality of roller brushes 504 are rotatably connected inside the waste box 501, and the roller brushes 504 are in frictional contact with the supporting mechanism 3, and one side of the waste box 501 is connected to the driving mechanism 6, and the driving mechanism is used to drive the roller brush 504 to rotate.

[0094] On the basis of the above-mentioned solution, the present application provides a prefabricated concrete component strength detection device, wherein the driving mechanism 6 includes a driving column 601 , a driving member 602 and a driving wheel 603 .

[0095] The driving columns 601 are arranged at both ends of the support frame 1; the conveying mechanism 2 is arranged on the driving columns 601;

[0096] The driving member 602 is fixedly mounted on the support frame 1, the output end of the driving member 602 is connected and fixed to one of the driving columns 601, and the conveying mechanism 2 and the driving column 601 are frictionally driven;

[0097] The driving wheel 603 is fixedly connected to one of the driving columns 2; the driving wheel 603 is connected to the cleaning component 5 through a transmission member.

[0098] On the basis of the above-mentioned solution, the present application provides a precast concrete component strength detection device, wherein the detection mechanism 4 includes a fixing frame 401 and an electric hydraulic rod 402 .

[0099] The fixed frame 401 is arranged on one side of the conveying mechanism 2; the electric hydraulic rod 402 is fixedly installed on the fixed frame 4, and a detection head 403 is installed on one side of the telescopic end of the electric hydraulic rod 402, and a pressure sensor 404 is connected between the detection head 403 and the telescopic end of the electric hydraulic rod 402.

[0100] On the basis of the above scheme, the concrete precast component strength detection device provided in the present application has a protective tube 405 provided on the outer sliding sleeve of the detection head 403, the protective tube 405 is in active contact with the bearing mechanism 3, and a third spring 406 is fixedly connected between the protective tube 405 and the outer wall of the detection head 403.

[0101] Reference Figure 1 , Figure 2 and Figure 3 The embodiment of the present application discloses a strength testing device for precast concrete components. The conveying mechanism 2 of the present application is a conveyor belt, and the driving member 602 is a motor. Under the control of an external control mechanism, the driving member 602 runs intermittently, and the conveying mechanism 2 intermittently drives the testing plate 301 and the concrete component samples above it to move. When the testing plate 301 and the corresponding samples move to the bottom of the testing head 403, under the action of the electric hydraulic rod 402, the testing head 403 moves downward to perform strength testing on the samples, so that the staff can conveniently and quickly perform continuous strength testing on batches of concrete component samples. Moreover, when the testing plate 301 drives the samples to move to the bottom of the conveyor belt after testing, the tested samples will be automatically poured out under the action of gravity, without the need for manual cleaning by the staff, effectively improving the efficiency of strength testing of precast concrete components.

[0102] Reference Figure 3 , Figure 4 and Figure 5 On the basis of the above scheme, after the staff places the sample to be tested on the detection plate 301, when the conveyor belt drives the detection plate 301 and the driving wheel 3411 to move to the top plate 341, the driving wheel 3411 drives the moving frame 342 and the rack 345 to slide to one side under the push of the top plate 341, and since the rotating gear 346 is meshed and connected with the rack 345, the rotating gear 346 then drives the driving disk 302 to rotate;

[0103] The driving groove 321 pushes the guide post 331. Due to the limiting effect of the limiting groove 311, the guide post 331 will drive the receiving plate 332 and the pushing plate 333 to move inward, pushing the sample to be tested to the center position of the testing plate 301, thereby effectively ensuring the smoothness and accuracy of the strength test.

[0104] After the push plate 333 contacts the sample to be tested, when the rotating gear 346 continues to drive the driving disk 302 to rotate, the guide column 331 will drive the receiving plate 332 to continue to move inward. However, due to the setting of the first spring 334, the push plate 333 has a certain elasticity, so that the technical solution is applicable to concrete precast samples of different sizes.

[0105] On the basis of the above solution, a magnet 7 is installed on the other side of the conveying mechanism 2, and the connecting frame 348 is magnetically matched with the magnet 7.

[0106] During the movement of the rack 345, the serrated plate 347 moves along with it. Since the positioning teeth 349 are engaged with the serrated plate 347, under the action of the fourth spring 3410, the positioning teeth 349 will limit the serrated plate 347, thereby ensuring that the push plate 333 is closely attached to the outside of the sample to be tested. This method can ensure the stability of the sample placement during the detection process on the one hand, and on the other hand, during the downward movement of the detection plate 301, the moving frame 342 and the pushing wheel 3411 can be prevented from extending outward, effectively reducing the required width of the waste box 501 and improving the practicality of the technical solution. In addition, when the detection plate 301 drives the connecting frame 348 to move to the magnet 7, due to the magnetic cooperation between the connecting frame 348 and the magnet 7, the connecting frame 348 will drive the positioning teeth 349 to move downward. At this time, under the action of the second spring 344, the pushing wheel 3411 and the rack 345 are quickly reset, which is convenient for the staff to use later.

[0107] Reference Figure 1 , Figure 2 , Figure 3 and Figure 6A third spring 406 is fixedly connected between the protective tube 405 and the outer wall of the detection head 403. When the detection head 403 moves downward to perform strength detection on the sample, the protective tube 405 will first contact the corresponding detection plate 301 and cover the outer side thereof, thereby blocking the flying debris, dust, etc. during the detection process, which can not only ensure the cleanliness of the detection environment, but also effectively provide effective protection for the staff, greatly improving the safety of the technical solution.

[0108] Reference Figure 1 and Figure 7 When the detection plate 301 drives the detected samples to move to the upper side of the waste bin 501, the fallen samples will fall into the waste bin 501, and because the receiving shell 503 is arranged in an arc-shaped structure, the broken samples can also slide through the receiving shell 503 to the waste bin 501, so that the detected samples can be completely collected in the waste bin 501, which greatly reduces the difficulty of subsequent processing by the staff.

[0109] A plurality of roller brushes 504 are rotatably connected in the waste box 501 . The roller brushes 504 are in frictional contact with the detection plate 301 . The driving mechanism is used to drive the roller brushes 504 to rotate.

[0110] Specifically, a belt 604 is installed on one side of the support frame 1, and the driving wheel 603 and the belt 604 are frictionally driven. The end of the roller brush 504 is also fixedly connected to a connecting gear 605, and adjacent connecting gears 605 are meshed and connected.

[0111] When the driving member 602 is running and the column 601 is driven to rotate, the roller brush 504 will rotate under the connection of the belt 604, the connecting gear 605 and the driving wheel 603. When the detection plate 301 moves to the roller brush 504, the rolling roller brush 504 can sweep the detection plate 301 to remove the gravel and dust adhered to the surface of the detection plate 301, without the need for manual cleaning by the staff, thereby further improving the efficiency of strength testing of precast concrete components.

[0112] The precast concrete component strength detection method described in this embodiment is implemented based on any one of the precast concrete component strength detection devices described above, and comprises the following steps:

[0113] S1. The staff places the sample to be tested on the test plate 301, the driving member 602 operates intermittently, and the conveying mechanism 2 intermittently drives the test plate 301 and the concrete component sample above it to move to one side;

[0114] S2. When the detection plate 301 and the pushing wheel 3411 move to the top plate 341, the guide pillar 331 drives the receiving plate 332 and the pushing plate 333 to move inward, pushing the sample to be tested to the center of the detection plate 301;

[0115] S3. When the detection plate 301 drives the corresponding sample to move below the detection head 403, the detection head 403 and the protective tube 405 move downward under the action of the electric hydraulic rod 402. The protective tube 405 is covered on the outside of the detection plate 301, and the detection head 403 detects the sample.

[0116] S4. After one test is completed, the test head 403 and the protective tube 405 are reset, the driving member 602 continues to operate, and the tested sample falls into the waste box 501;

[0117] S5. Under the connection between the belt 604, the connecting gear 605 and the driving wheel 603, the roller brush 504 rotates to sweep the detection plate 301 passing through the roller brush 504 to remove the gravel and dust adhering to the surface of the detection plate 301.

[0118] The implementation principle of the precast concrete component strength testing device of the embodiment of the present application is as follows: when relevant staff need to use the present technical solution to perform continuous strength testing on batches of precast concrete component samples, the staff first places the samples to be tested on the testing plate 301, and under the control of the external control mechanism, the driving member 602 runs intermittently, and the conveying mechanism 2 intermittently drives the testing plate 301 and the concrete component samples above it to move.

[0119] When the detection plate 301 and the pushing wheel 3411 move to the top plate 341, under the push of the top plate 341, the pushing wheel 3411 will drive the moving frame 342 and the rack 345 to slide to one side, and the rotating gear 346 will then drive the driving disk 302 to rotate, and the guide column 331 will then drive the receiving plate 332 and the pushing plate 333 to move inward, pushing the sample to be tested to the center position of the detection plate 301.

[0120] When the rack 345 moves, the sawtooth plate 347 moves accordingly. Under the action of the fourth spring 3410 , the positioning teeth 349 limit the sawtooth plate 347 , so that the push plate 333 fits tightly against the outside of the sample to be tested.

[0121] As the conveying mechanism 2 continues to rotate, when the detection plate 301 drives the corresponding sample to move below the detection head 403, the driving member 602 stops running, and the detection head 403 moves downward under the action of the electric hydraulic rod 402 to perform strength detection on the sample. During this process, the protective tube 405 will first contact the corresponding detection plate 301 and cover its outer side to block the splashing debris, dust, etc. generated by the detection.

[0122] After one test is completed, the test head 403 and the protective tube 405 are reset, and the driving member 602 continues to operate. When the test plate 301 drives the tested sample to move to the upper side of the waste box 501, the tested sample will fall into the waste box 501. At the same time, under the connection of the belt 604, the connecting gear 605 and the driving wheel 603, the roller brush 504 rotates to sweep the test plate 301 passing through the roller brush 504, and remove the gravel and dust adhering to the surface of the test plate 301.

[0123] When the detection plate 301 drives the connecting frame 348 to move to the magnet 7, the connecting frame 348 drives the positioning tooth 349 to move downward due to the magnetic cooperation between the connecting frame 348 and the magnet 7. At this time, under the action of the second spring 344, the push wheel 3411 and the rack 345 are quickly reset. In this way, the staff can conveniently and quickly perform continuous inspections on the precast concrete parts.
