DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] In the embodiment of the present invention, please refer to Figures 1 to 5 , a construction concrete quality detection device, comprising a detection box 1 and a sealing door 2, wherein the sealing door 2 is connected to the front of the detection box 1 through a hinge, and further comprising: The top of the telescopic member 3 is connected to the top of the detection box 1; The upper pressing block 4 is connected to the bottom end of the telescopic member 3; The lower support platform 5 is located at the bottom of the upper pressing block 4 and is rotatably connected to the detection box body 1; The bottom end of the telescopic member 2 6 is connected to the back of the detection box 1; A connecting plate 7 connected to the top of the telescopic member 2 6; A bottom support mechanism 8, one end of which is connected to the connecting plate 7, and the other end of which is in contact with the bottom of the lower support platform 5, for supporting and limiting the lower support platform 5; The debris cleaning mechanism 9 is used to clean the debris on the lower support 5, and the debris cleaning mechanism 9 includes: An irregular swing component 91, one end of which is connected to the lower support platform 5, and the other end of which is connected to the detection box 1, and is used to drive the lower support platform 5 to swing back and forth; The lifting and contracting assembly 92 is connected to the connecting plate 7 and is used to drive the irregular swing assembly 91 to move; The magnetic attraction component 93 is connected to the lifting and contracting component 92 and to the back of the detection box 1, and is used to fix the lifting and contracting component 92 when it moves laterally.

[0019] In the initial state, the bottom support mechanism 8 supports the lower platform 5, the concrete block to be tested is placed on the lower platform 5, the sealing door 2 is covered, and the telescopic member 1 3 drives the upper pressure block 4 to press down to perform pressurized testing on the concrete block. During the testing process, the pressure data is transmitted to the computer (not shown in the figure) through the controller (not shown in the figure). After the test is completed, the telescopic member 1 3 moves in the opposite direction to drive the upper pressure block 4 back to the original position, and the telescopic member 2 6 drives the connecting plate 7 to move upward, and the connecting plate 7 drives the bottom support mechanism 8 and the lifting and contraction assembly 92 to move, and the limit of the bottom support mechanism 8 on the lower platform 5 is released. After the release, the connecting plate 7 continues to move upward, so that the lifting and contraction assembly 92 moves to The irregular swing component 91 is abutted against the irregular swing component 91, so that the irregular swing component 91 moves, drives the lower platform 5 to rotate, and causes large pieces of concrete to fall downward. When the lower platform 5 rotates to the maximum angle (greater than or equal to 90 degrees), the irregular swing component 91 cannot continue to move. At this time, the lifting and contracting component 92 moves horizontally, driving the magnetic suction component 93 to move horizontally. When the magnetic suction component 93 is magnetically adsorbed together, the lifting and contracting component 92 moves horizontally to the maximum distance. At this time, the lifting and contracting component 92 is separated from the irregular swing component 91, and the irregular swing component 91 drives the lower platform 5 to reciprocate, and the rotation angle keeps changing, so that the small pieces of concrete adhered to the lower platform 5 fall. The telescopic member 1 3 and the telescopic member 2 6 can both be electric telescopic rods, cylinders, etc.

[0020] As an embodiment of the present invention, please refer to Figures 1 to 4 , the bottom support mechanism 8 comprises: The sliding plug rod 81 is connected to the bottom of the connecting plate 7; The fixed cylinder 82 is connected to the back of the detection box 1 and is slidably engaged with the sliding plug rod 81; Folding tubes 83, two groups of the folding tubes 83 are provided and symmetrically located on both sides of the fixed tube 82, and one end of the folding tube 83 is connected to the interior of the fixed tube 82; The support tubes 84 are provided with several groups, two groups of the support tubes 84 penetrate the detection box 1 and are slidably connected thereto, two groups of the support tubes 84 are slidably connected to the folding tubes 83 and are slidably connected thereto, and the other groups of the support tubes 84 are connected to the inner wall of the detection box 1.

[0021] In the initial state, the sliding support tube 84 is located at the bottom of the lower platform 5 to support it, and the telescopic member 6 drives the connecting plate 7 to move, and the connecting plate 7 drives the sliding plug rod 81 to move, and the gas in the support tube 84 is drawn into the fixed tube 82, so that the sliding support tube 84 moves and separates from the lower platform 5. When the sliding support tube 84 moves to separate from the lower platform 5, the sliding plug rod 81 separates from the fixed tube 82, the support tube 84 cannot continue to move, and the connecting plate 7 continues to move.

[0022] As an embodiment of the present invention, please refer to Figures 1 to 4 , the irregular swing component 91 comprises: Gear 911, connected to lower support platform 5; The tooth plate 912 is meshed with the gear 911 and is slidably connected to the side wall of the detection box 1; A folding rod 913, one end of which is connected to the tooth plate 912; An oblique straight plate 914 is connected to the other end of the folding rod 913, wherein the bottom of the oblique straight plate 914 is an oblique edge structure and the top is a straight edge structure; The elastic member 915 has one end connected to the back of the detection box 1 and the other end connected to the folding rod 913 .

[0023] The connecting plate 7 drives the lifting and contracting assembly 92 to move upward. When the lifting and contracting assembly 92 moves upward to abut against the inclined straight plate 914, the inclined straight plate 914 is driven to overcome the reaction force of the elastic member 915 and move upward synchronously. The inclined straight plate 914 drives the tooth plate 912 to move upward, and the tooth plate 912 drives the gear 911 to rotate, thereby driving the lower support platform 5 to rotate a certain angle, so that the fragments on the lower support platform 5 slide and fall. When the inclined straight plate 914 moves to the maximum distance, the lifting and contracting assembly 92 continues to move upward and moves laterally at the same time. When the magnetic suction assembly 93 moves to be magnetically attracted together, the lifting and contracting assembly 92 cannot move laterally. At this time, there is a gap between the lifting and contracting assembly 92 and the straight plate structure side of the inclined straight plate 914. Under the reaction force of the elastic member 915, the lower support platform 5 rotates in the opposite direction, and the elastic member 915 repeatedly shakes, so that the lower support platform 5 rotates back and forth continuously, and the rotation angle changes, so that the fragments on the lower support platform 5 fall. The elastic member 915 can be a spring with good reciprocating shaking effect, such as a spring coil.

[0024] As an embodiment of the present invention, please refer to Figures 3 to 5 The lifting and retracting assembly 92 includes: The connecting tube 921 is connected to the connecting plate 7. The connecting tube 921 is provided with two groups and is symmetrically arranged; The sliding rod 922 penetrates the connecting tube 921 and is slidably connected thereto; The squeezing roller 923 is connected to one end of the sliding rod 922; The piston block 924 is located inside the connecting tube 921 and is slidably engaged with the inner wall thereof. The piston block 924 is connected to the sliding rod 922; The second elastic member 925 is sleeved on the sliding rod 922, and one end of the elastic member is connected to the piston block 924, and the other end of the elastic member is connected to the connecting tube 921; The air outlet pipe 926 is connected to the interior of the connecting tube 921; The air inlet pipe 927 is connected to the interior of the connecting tube 921, and a one-way valve is provided inside the air inlet pipe 927; The blocking component 928 has one end connected to the connecting tube 921 and the other end abutting against the air outlet pipe 926 for blocking the air outlet pipe 926 .

[0025] In the initial state, the blocking component 928 is in contact with the outlet pipe 926. When the extrusion roller 923 is in contact with one side of the oblique side of the oblique straight plate 914, the blocking component 928 is in a blocking state against the outlet pipe 926, so that the gas inside the connecting tube 921 cannot flow out, resulting in the sliding rod 922 being unable to move laterally, thereby driving the oblique straight plate 914 to move upward synchronously. When the oblique straight plate 914 moves to the highest position, the oblique straight plate 914 cannot continue to move, and the extrusion roller 923 continues to move upward, so that the sliding rod 922 drives the piston block 924 to move laterally, the air pressure increases, the blocking component 928 is separated from the outlet pipe 926, and the gas flows out. The second elastic member 925 can be a spring, a spring sheet, etc.

[0026] As an embodiment of the present invention, please refer to Figures 3 to 5 , the blocking assembly 928 comprises: A fixing rod 9281, one end of which is connected to the connecting tube 921; The sliding folding rod 9282 is slidably connected to the fixed rod 9281; The elastic member 3 9283 has one end connected to the other end of the fixed rod 9281 and the other end connected to the sliding folding rod 9282; The blocking plate 9284 is connected to the sliding folding rod 9282 and abuts against the air outlet pipe 926.

[0027] When the piston block 924 is pushed upward, the air pressure increases, causing the blocking plate 9284 to separate from the air outlet pipe 926, and the air flows out from the air outlet pipe 926. At the same time, the sliding rod 922 drives the magnetic suction component 93 to move. When the magnetic suction component 93 is adsorbed together, the sliding rod 922 cannot continue to move laterally. Under the reaction force of the elastic component 3 9283, the blocking plate 9284 blocks the air outlet pipe 926 again. The elastic member three 9283 can be a spring, a spring sheet, etc.

[0028] As an embodiment of the present invention, please refer to Figures 3 to 5 , the magnetic attraction component 93 includes: Magnet blocks 931, wherein two groups of magnet blocks 931 are provided and are respectively connected to the other ends of the two groups of sliding rods 922, the two groups of magnet blocks 931 have opposite magnetic properties, and the bottom of the side close to each other is a bevel structure; The partitioning bevel block 932 is connected to the detection box 1 and is located between the two groups of magnet blocks 931 . Both sides of the partitioning bevel block 932 are bevel structures.

[0029] In the initial state, the two groups of magnet blocks 931 are in a separated state. When the connecting plate 7 moves upward, since the elastic member 3 9283 is in a stretched state, the blocking plate 9284 blocks the air outlet pipe 926, so that when the extrusion roller 923 abuts against one side of the oblique edge of the oblique straight plate 914, the oblique straight plate 914 is driven to move upward synchronously. When the oblique straight plate 914 moves to the highest position, the oblique straight plate 914 cannot continue to move, and the extrusion roller 923 continues to move upward. The sliding rod 922 drives the magnet blocks 931 to approach each other, and the elastic member 2 925 undergoes elastic deformation. As the magnet blocks 931 approach each other, the magnetic attraction gradually increases. When the magnetic attraction is greater than When the elastic member 925 rebounds, the two groups of magnet blocks 931 are adsorbed together. At this time, there is a distance between the extrusion roller 923 and the straight edge structure of the inclined straight plate 914. Under the reaction force of the elastic member 915, the tooth plate 912 vibrates longitudinally, thereby driving the lower support platform 5 to reciprocate, and the rotation angle changes all the time. The connecting plate 7 moves downward, driving the magnet block 931 to move downward. When the magnet block 931 moves to abut against the separating inclined block 932, the two groups of magnet blocks 931 are separated under the isolation effect of the separating inclined block 932, and the sliding rod 922 returns to its original position under the reaction force of the elastic member 925.

[0030] As an embodiment of the present invention, a storage box for storing broken pieces is placed at the bottom of the detection box 1.

[0031] A storage box (not shown) is placed at the bottom of the detection box 1 to collect concrete fragments.

[0032] The working principle of the present invention is as follows: in the initial state, the support tube 84 is slidably arranged at the bottom of the lower support platform 5 to support it, the concrete block to be tested is placed on the lower support platform 5, the sealing door 2 is covered, the telescopic member 1 3 drives the upper pressing block 4 to press down, and the concrete block is pressurized for testing. During the testing process, the pressure data is transmitted to the computer through the controller. After the testing is completed, the telescopic member 1 3 moves in the opposite direction to drive the upper pressing block 4 back to the original position, the telescopic member 2 6 drives the connecting plate 7 to move upward, and the connecting plate 7 drives the sliding plug rod 81 to move, and the support tube 84 is placed on the lower support platform 5. The gas in the support tube 84 is drawn into the fixed tube 82, so that the sliding support tube 84 moves and separates from the lower support platform 5. When the sliding support tube 84 moves to separate from the lower support platform 5, the sliding plug rod 81 separates from the fixed tube 82, the support tube 84 cannot continue to move, and the connecting plate 7 continues to move. When the extrusion roller 923 abuts against one side of the oblique edge of the inclined straight plate 914, the gas in the connecting tube 921 cannot flow out, causing the sliding rod 922 to be unable to move laterally, thereby driving the inclined straight plate 914 to move upward synchronously, and the inclined straight plate 914 drives the toothed plate 91 2 moves upward, the toothed plate 912 drives the gear 911 to rotate, and then drives the lower platform 5 to rotate a certain angle, so that the broken pieces on the lower platform 5 slide and fall. When the inclined straight plate 914 moves to the maximum distance, the extrusion roller 923 continues to move upward, the sliding rod 922 drives the magnet blocks 931 to approach each other, and the elastic member 925 undergoes elastic deformation. As the magnet blocks 931 approach each other, the magnetic attraction gradually increases. When the magnetic attraction is greater than the rebound force of the elastic member 925, the two groups of magnet blocks 931 are adsorbed together. At this time, the extrusion roller 92 There is a distance between the straight edge structure of the inclined straight plate 914 and the tooth plate 912 under the reaction force of the elastic member 1 915, so that the tooth plate 912 vibrates longitudinally, thereby driving the lower support platform 5 to reciprocate, and the rotation angle changes all the time, and then the connecting plate 7 moves downward, driving the magnet block 931 to move downward, when the magnet block 931 moves to abut against the separating inclined block 932, under the isolation effect of the separating inclined block 932, the two groups of magnet blocks 931 are separated, and under the reaction force of the elastic member 2 925, the sliding rod 922 returns to its original position.
