Description

Technical Field

[0001] This utility model relates to the field of concrete block testing technology, specifically a strength testing device for concrete production. Background Technology

[0002] Concrete is one of the most important civil engineering materials in modern times. Concrete is characterized by abundant raw materials, low price, and simple production process, which leads to its increasing use. At the same time, concrete also has the characteristics of high compressive strength, good durability, and a wide range of strength grades. These characteristics make its application very extensive. It is used not only in various civil engineering projects, but also in shipbuilding, machinery industry, marine development, geothermal engineering, etc. Concrete is also an important material. Before concrete leaves the factory and is put into use, it needs to be subjected to strength testing, which requires the use of strength testing equipment.

[0003] Existing strength testing equipment typically involves personnel placing the concrete test block on top of a load-bearing plate, then using a cylinder to press a pressure plate down on top of the block. Continuous pressure is used to test the concrete's strength. After testing, the top of the load-bearing plate is often covered with stone debris and broken stones. Because there is only one load-bearing plate, workers must clean it thoroughly before placing the next test block and conducting the next strength test. This results in a long waiting period and reduces the efficiency of concrete test. Therefore, we propose a new strength testing device for concrete production. Utility Model Content

The two guide rods are respectively connected between the two sides of the inner wall of the two transverse grooves. The two racks are respectively slidably connected to the outer surface of the two guide rods. The two mounting brackets are each connected to the top of the two racks. The two load-bearing plates are respectively connected to the bottom of the inner wall of the two mounting brackets.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1:

[0026] Please see Figures 1 to 7 In this embodiment of the present invention, a strength testing device for concrete production includes: a support platform 1, a fixed frame 2 connected to the top of the support platform 1, two horizontal slots opened on the top of the support platform 1, a moving mechanism 3 arranged between the two horizontal slots, and the moving mechanism 3 extending to the top of the support platform 1, a driving mechanism 4 arranged at the bottom of the support platform 1, and the driving mechanism 4 engaging with the moving mechanism 3, a testing mechanism 5 arranged on the top of the fixed frame 2, and the testing mechanism 5 extending into the interior of the fixed frame 2, and two collection boxes 8 connected to the back of the support platform 1, and a buffer mechanism 9 arranged inside the two collection boxes 8.

[0027] Specifically, after the concrete block is placed on the moving mechanism 3 located inside the fixed frame 2, the detection mechanism 5 is activated to descend and block both sides of the fixed frame 2. At the same time, the detection mechanism 5 can continuously squeeze the concrete block to test its strength. After the concrete block is tested, the detection mechanism 5 will stop squeezing the concrete block and rise, no longer blocking both sides of the fixed frame 2. At this time, the drive mechanism 4 is activated to drive the moving mechanism 3 to move the tested concrete block to the outside of the fixed frame 2 and the untested concrete block to the inside of the fixed frame 2. Then, one of the pushing components 6 is activated to push the tested concrete block on the moving mechanism 3 into the inside of one of the collection boxes 8 through one of the inclined platforms 7 for collection. Then, the concrete block to be tested can be placed on the moving mechanism 3, and the above operation is repeated. This not only cleans the concrete block on the moving mechanism 3, but also improves the efficiency of concrete block testing. After the concrete block falls into the inside of one of the collection boxes 8, it will squeeze one of the buffer mechanisms 9 for double compression, thereby doubly buffering the impact force of the fall, reducing the damage to one of the collection boxes 8, and extending the service life of one of the collection boxes 8.

[0028] Example 2:

[0029] Please see Figures 5-6In this embodiment of the present invention, a strength testing device for concrete production includes a moving mechanism 3 comprising two guide rods 301, two racks 302, two mounting brackets 303, and two load-bearing plates 304. The two guide rods 301 are respectively connected between the two sides of the inner walls of two transverse grooves. The two racks 302 are slidably connected to the outer surfaces of the two guide rods 301. The two mounting brackets 303 are each connected to the top of the two racks 302. The two load-bearing plates 304 are each connected to the bottom of the inner walls of the two mounting brackets 303. The driving mechanism 4 comprises a U-shaped frame 401, a rotating rod 402, two gears 403, and a forward and reverse servo motor 404. The U-shaped frame 401 is connected to the bottom of the support platform 1. The rotating rod 402 is rotatably connected between the front and back sides of the inner wall of the U-shaped frame 401, with one end of the rotating rod 402 extending to the front of the U-shaped frame 401. The two gears 403 are fixedly connected to the outer surfaces of the rotating rod 402, and each gear 403 meshes with one of the racks 302. A forward and reverse servo motor 404 is connected to the front of the U-shaped frame 401, and one end of the output shaft of the forward and reverse servo motor 404 is connected to one end of the rotating rod 402. The detection mechanism 5 includes a cylinder 501, a pressure plate 502, a U-shaped frame 503, two hollow plates 504, two baffles 505, and two return springs 506. The cylinder 501 is connected to the top of the fixed frame 2, and the output end of the cylinder 501 extends into the interior of the fixed frame 2. The pressure plate 502 is connected to the output end of the cylinder 501. The U-shaped frame 503 is connected to the outer surface of the output end of the cylinder 501, and both ends of the U-shaped frame 503 extend to the top of the fixed frame 2. Two hollow plates 504 are respectively connected to the two sides of the U-shaped frame 503. Two baffles 505 are respectively movably connected to the inside of the two hollow plates 504, and the bottom ends of the two baffles 505 extend to the bottom of the two hollow plates 504. Two return springs 506 are respectively connected between the top of the inner wall of the two hollow plates 504 and the top of the two baffles 505.

[0030] Specifically, a concrete block is placed on top of one of the load-bearing plates 304. The output end of cylinder 501 extends, causing pressure plate 502 and U-shaped frame 503 to descend. Pressure plate 502 presses down on the top of the concrete block, while U-shaped frame 503 lowers two hollow plates 504 into the fixed frame 2. Two baffles 505 shield the sides of the fixed frame 2 to prevent the concrete block from flying off during testing, causing debris to scatter. After testing, the output end of cylinder 501 retracts, causing the two hollow plates... When 504 rises, it no longer obstructs the sides of the fixed frame 2. The output shaft of the forward and reverse servo motor 404 is started, which drives the two gears 403 to rotate through the rotating rod 402. The two gears 403 push the two racks 302 to slide on the outer surface of the two guide rods 301. When one end of the two racks 302 is in contact with one side of the inner wall of the two transverse grooves, it will drive one of the mounting brackets 303 to move to the outside of the fixed frame 2, while the other mounting bracket 303 will move to the inside of the fixed frame 2. At this time, the detection mechanism 5 can detect the concrete block again.

[0031] Example 3:

[0032] Please see Figures 1 to 7 In this embodiment of the present invention, a strength testing device for concrete production includes a buffer mechanism 9 comprising two first damping springs 901, an iron plate 902, a pressing block 903, two mounting plates 904, two second damping springs 905, and two pressure blocks 906. The two first damping springs 901 are connected to the bottom of the inner wall of one of the collection boxes 8. The iron plate 902 is connected to the top of the two first damping springs 901. The pressing block 903 is connected to the bottom of the iron plate 902. The two mounting plates 904 are fixed... The bottom of the inner wall of one of the collection boxes 8 is fixedly connected. Two second damping springs 905 are respectively connected to the adjacent side of the two mounting plates 904. Two pressure blocks 906 are respectively connected to the adjacent side of the two second damping springs 905. The two ends of the squeezing block 903 are in contact with the adjacent side of the two pressure blocks 906. Two pusher assemblies 6 are connected to the top of the support platform 1. Two inclined platforms 7 are connected to the top of the support platform 1. Multiple support legs 11 are connected to the bottom of the support platform 1. A transparent plate 10 is hinged to the front of the fixed frame 2.

[0033] Specifically, activating one of the pushing components 6 pushes the concrete block on the load-bearing plate 304 outside the fixed frame 2 into the interior of one of the collection boxes 8. The concrete block, guided by one of the inclined platforms 7, falls into the interior of one of the collection boxes 8 and lands on top of the iron plate 902. The impact force of the fall presses the iron plate 902 down and compresses the two first damping springs 901, thus initially buffering the impact force. At the same time, the iron plate 902 drives the pressing block 903 down, which compresses the two pressure blocks 906 to move in opposite directions, thereby compressing the two second damping springs 905, further buffering the impact force, thus effectively reducing the damage to one of the collection boxes 8. The setting of multiple support legs 11 can improve the stability of the equipment. The setting of transparent plate 10 makes it easy to put concrete into the interior of the fixed frame 2 and observe the internal condition of the fixed frame 2.

[0034] The working principle of this utility model is as follows: When testing concrete, the operator first opens the transparent plate 10 and places the concrete block inside the fixing frame 2. At this time, the concrete block is located on top of one of the load-bearing plates 304. Then, the transparent plate 10 is closed, and the cylinder 501 is activated. The output end of the cylinder 501 extends, driving the pressure plate 502 and the U-shaped frame 503 to descend. The pressure plate 502 descends to the top of the concrete block and continuously presses the concrete block. The pressure sensor on the pressure plate 502 can detect the compressive strength of the concrete. As the U-shaped frame 503 descends, it drives two... The hollow plate 504 descends into the interior of the mounting frame 2. At this time, the two baffles 505 will abut against the top ends of one of the mounting brackets 303. As the pressure plate 502 continues to descend, the two hollow plates 504 will respectively compress the two return springs 506, so that the two baffles 505 can continuously shield the sides of the mounting frame 2 to prevent the flying of gravel. After the concrete block is detected, the output end of the cylinder 501 retracts, and the forward and reverse servo motor 404 is activated. The output shaft of the forward and reverse servo motor 404 drives the two gears 403 to rotate through the rotating rod 402. When activated, the two racks 302 can slide on the outer surface of the two guide rods 301 facing the support platform 1 until one end of the two racks 302 is in contact with one side of the inner wall of the two transverse grooves. After the concrete block mounting bracket 303 is inspected, it will move to the outside of the fixed frame 2, and the uninspected mounting bracket 303 will move to the inside of the fixed frame 2. At this time, the inspection mechanism 5 can inspect the concrete block again. Then, the operator can activate one of the pushing components 6, which can push the concrete block on top of the load-bearing plate 304 located outside the fixed frame 2 into one of the collection boxes 8. When the concrete block is pushed, it falls into the interior of one of the collection boxes 8 through the guide of one of the inclined platforms 7, and then falls on top of the iron plate 902. The impact force of the fall will press the iron plate 902 down. When the iron plate 902 falls, it will squeeze the two first damping springs 901 to compress it, and initially buffer the impact force. At the same time, the pressing block 903 continues to fall and squeezes the two pressure blocks 906, causing the two pressure blocks 906 to move in opposite directions and squeeze the two second damping springs 905 to compress it, thereby further buffering the impact force and reducing the damage to one of the collection boxes 8.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
