Specific implementation manners

[0052] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0053] In the embodiments of the present invention, please refer to Figures 1 to 5 , a concrete quality detection device for construction, including a detection box body 1 and a sealing door 2, the sealing door 2 is connected to the front of the detection box body 1 through a hinge, and further includes:

[0054] The first telescopic member 3, the top of which is connected to the top of the detection box body 1;

[0055] The upper pressing block 4, which is connected to the bottom end of the first telescopic member 3;

[0056] The lower bearing platform 5, which is located below the upper pressing block 4 and is rotatably connected to the detection box body 1;

[0057] The second telescopic member 6, the bottom of which is connected to the back of the detection box body 1;

[0058] The connecting plate 7, which is connected to the top end of the second telescopic member 6;

[0059] The bottom support mechanism 8, one end of which is connected to the connecting plate 7 and the other end is abutted against the bottom of the lower bearing platform 5 for supporting and limiting the lower bearing platform 5;

[0060] The debris cleaning mechanism 9 is used to clean the debris on the lower bearing platform 5. The debris cleaning mechanism 9 includes:

[0061] The irregular swing assembly 91 is connected to the lower bearing platform 5 at one end and the detection box body 1 at the other end, and is used to drive the lower bearing platform 5 to swing reciprocally;

[0062] The lifting and horizontal contraction assembly 92 is connected to the connecting plate 7 and is used to drive the irregular swing assembly 91 to move;

[0063] The magnetic attraction assembly 93 is connected to the lifting and horizontal contraction assembly 92 and is connected to the back of the detection box body 1, and is used to fix the lifting and horizontal contraction assembly 92 when it moves horizontally.

[0064] In the initial state, the bottom support mechanism 8 supports the lower bearing platform 5. The concrete block to be detected is placed on the lower bearing platform 5, the sealing door 2 is covered, the first telescopic member 3 drives the upper pressing block 4 to press down to perform a pressure test on the concrete block. During the test, the pressure data is transmitted to a computer (not shown in the figure) through a controller (not shown in the figure). After the test is completed, the first telescopic member 3 moves in the reverse direction to drive the upper pressing block 4 back to the original position. The second telescopic member 6 drives the connecting plate 7 to move upward. The connecting plate 7 drives the bottom support mechanism 8 and the lifting and horizontal contraction assembly 92 to move, releasing the limit of the bottom support mechanism 8 on the lower bearing platform 5. After the release, the connecting plate 7 continues to move upward, causing the lifting and horizontal contraction assembly 92 to move to abut against the irregular swing assembly 91, causing the irregular swing assembly 91 to move, driving the lower bearing platform 5 to rotate, so that large concrete debris falls downward. When the lower bearing platform 5 rotates to the maximum angle (greater than or equal to 90 degrees), the irregular swing assembly 91 cannot continue to move. At this time, the lifting and horizontal contraction assembly 92 moves horizontally, driving the magnetic attraction assembly 93 to move horizontally. When the magnetic attraction assemblies 93 are magnetically attracted together, the lifting and horizontal contraction assembly 92 moves horizontally to the maximum distance. At this time, the lifting and horizontal contraction assembly 92 disengages from the irregular swing assembly 91, and the irregular swing assembly 91 drives the lower bearing platform 5 to rotate reciprocally, and the rotation angle changes continuously, causing the small concrete debris adhering to the lower bearing platform 5 to fall off. The first telescopic member 3 and the second telescopic member 6 can both adopt electric telescopic rods, cylinders, etc.

[0065] As an embodiment of the present invention, please refer to Figures 1 to 4 , the bottom support mechanism 8 includes:

[0066] The sliding plug rod 81 is connected to the bottom of the connecting plate 7;

[0067] The fixed cylinder 82 is connected to the back of the detection box body 1 and is slidably clamped with the sliding plug rod 81;

[0068] The folding pipe 83, there are two groups of the folding pipes 83, and they are symmetrically located on both sides of the fixed cylinder 82. One end of the folding pipe 83 is communicated with the inside of the fixed cylinder 82;

[0069] The support pipes 84, there are several groups of the support pipes 84. Two groups of the support pipes 84 penetrate through the detection box body 1 and are slidably connected thereto. The two groups of the support pipes 84 are slidably connected with the folding pipes 83 and are slidably connected therewith. The other groups of the support pipes 84 are connected to the inner wall of the detection box body 1.

[0070] In the initial state, the slidably arranged support pipe 84 is located at the bottom of the lower bearing platform 5 to support it. The telescopic member two 6 drives the connecting plate 7 to move, and the connecting plate 7 drives the sliding plug rod 81 to move, pumping the gas in the support pipe 84 into the inside of the fixed cylinder 82, so that the slidably arranged support pipe 84 moves away from the lower bearing platform 5. When the slidably arranged support pipe 84 moves away from the lower bearing platform 5, the sliding plug rod 81 disengages from the fixed cylinder 82, and the support pipe 84 cannot move continuously, and the connecting plate 7 continues to move.

[0071] As an embodiment of the present invention, please refer to Figures 1 to 4 , the irregular swing assembly 91 includes:

[0072] The gear 911, connected to the lower bearing platform 5;

[0073] The toothed plate 912, meshing with the gear 911 and slidably connected to the side wall of the detection box body 1;

[0074] The folding rod 913, one end of which is connected to the toothed plate 912;

[0075] The inclined straight plate 914, connected to the other end of the folding rod 913. The bottom of the inclined straight plate 914 is a bevel structure, and the top is a straight edge structure;

[0076] The elastic member one 915, one end of which is connected to the back of the detection box body 1, and the other end is connected to the folding rod 913.

[0077] The connecting plate 7 drives the lifting and horizontal contraction assembly 92 to move upward. When the lifting and horizontal contraction assembly 92 moves upward to abut against the inclined straight plate 914, it drives the inclined straight plate 914 to move upward synchronously against the reaction force of the first elastic member 915. The inclined straight plate 914 drives the toothed plate 912 to move upward, and the toothed plate 912 drives the gear 911 to rotate, thereby driving the lower bearing platform 5 to rotate by a certain angle, causing the debris on the lower bearing platform 5 to slide and fall. When the inclined straight plate 914 moves to the maximum distance, the lifting and horizontal contraction assembly 92 continues to move upward and simultaneously undergoes a horizontal movement. When the magnetic attraction assembly 93 moves to the point where they are magnetically attracted together, the lifting and horizontal contraction assembly 92 cannot move horizontally. At this time, there is a gap between the lifting and horizontal contraction assembly 92 and the straight plate structure side of the inclined straight plate 914. Under the reaction force of the first elastic member 915, the lower bearing platform 5 rotates in the reverse direction, and the first elastic member 915 vibrates repeatedly, causing the lower bearing platform 5 to rotate back and forth continuously, and the rotation angle changes, causing the debris on the lower bearing platform 5 to fall. The first elastic member 915 can be a spring coil or other spring with good reciprocating vibration effect.

[0078] As an embodiment of the present invention, please refer to Figures 3 to 5 , the lifting and horizontal contraction assembly 92 includes:

[0079] Connecting cylinders 921, connected to the connecting plate 7, and there are two groups of the connecting cylinders 921, which are symmetrically arranged;

[0080] Sliding rods 922, passing through the connecting cylinders 921 and slidably connected thereto;

[0081] Extrusion rollers 923, connected to one end of the sliding rods 922;

[0082] Piston blocks 924, located inside the connecting cylinders 921 and slidably clamped with their inner walls, and the piston blocks 924 are connected to the sliding rods 922;

[0083] Second elastic members 925, sleeved on the sliding rods 922, with one end connected to the piston blocks 924 and the other end connected to the connecting cylinders 921;

[0084] Outlet pipes 926, communicating with the inside of the connecting cylinders 921;

[0085] Inlet pipes 927, communicating with the inside of the connecting cylinders 921, and one-way valves are provided inside the inlet pipes 927;

[0086] Blocking assemblies 928, with one end connected to the connecting cylinders 921 and the other end abutting against the outlet pipes 926, for blocking the outlet pipes 926.

[0087] In the initial state, the blocking component 928 abuts against the air outlet pipe 926. When the pressing roller 923 abuts against one side of the hypotenuse of the inclined straight plate 914, since the blocking component 928 blocks the air outlet pipe 926, the gas inside the connecting cylinder 921 cannot flow out, resulting in the inability of the sliding rod 922 to move horizontally. As a result, the inclined straight plate 914 is driven to move upward synchronously. When the inclined straight plate 914 moves to the highest position, it cannot continue to move. The pressing roller 923 continues to move upward, causing the sliding rod 922 to drive the piston block 924 to move horizontally, increasing the air pressure. The blocking component 928 disengages from the air outlet pipe 926, and the gas flows out. The second elastic member 925 can be a spring, a spring sheet, etc.

[0088] As an embodiment of the present invention, please refer to Figures 3 to 5 , the blocking component 928 includes:

[0089] A fixed rod 9281, one end of which is connected to the connecting cylinder 921;

[0090] A sliding folding rod 9282, which is slidably connected to the fixed rod 9281;

[0091] A third elastic member 9283, one end of which is connected to the other end of the fixed rod 9281, and the other end is connected to the sliding folding rod 9282;

[0092] A blocking plate 9284, which is connected to the sliding folding rod 9282 and abuts against the air outlet pipe 926.

[0093] In the initial state, the blocking plate 9284 abuts against the air outlet pipe 926, and the third elastic member 9283 is always in a stretched state. When the pressing roller 923 abuts against one side of the hypotenuse of the inclined straight plate 914, the gas inside the connecting cylinder 921 cannot flow out, resulting in the inability of the sliding rod 922 to move horizontally. As a result, the inclined straight plate 914 is driven to move upward synchronously. When the inclined straight plate 914 moves to the highest position, it cannot continue to move. The pressing roller 923 continues to move upward, causing the sliding rod 922 to drive the piston block 924 to move horizontally, increasing the air pressure. The blocking plate 9284 disengages from the air outlet pipe 926, and the gas flows out from the air outlet pipe 926. At the same time, the sliding rod 922 drives the magnetic attraction assembly 93. When the magnetic attraction assembly 93 adsorbs together, the sliding rod 922 cannot continue to move horizontally. Under the reaction force of the third elastic member 9283, the blocking plate 9284 re-blocks the air outlet pipe 926. The third elastic member 9283 can be a spring, a spring sheet, etc.

[0094] As an embodiment of the present invention, please refer to Figures 3 to 5 , the magnetic attraction assembly 93 includes:

[0095] Magnet blocks 931, there are two groups of the magnet blocks 931, and they 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 polarities, and the bottom of the sides facing each other is of a bevel structure;

[0096] Partition bevel block 932, connected to the detection box body 1 and located between the two groups of magnet blocks 931. The two sides of the partition bevel block 932 are of bevel structures.

[0097] 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 three 9283 is in a stretched state, the blocking plate 9284 blocks the air outlet pipe 926. When the pressing roller 923 abuts against the bevel side of the inclined straight plate 914, it drives the inclined straight plate 914 to move upward synchronously. When the inclined straight plate 914 moves to the highest position, the inclined straight plate 914 cannot move further. The pressing roller 923 continues to move upward, and the sliding rod 922 drives the magnet blocks 931 to approach each other. The elastic member two 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 restoring force of the elastic member two 925, the two groups of magnet blocks 931 are adsorbed together. At this time, there is a distance between the pressing roller 923 and the straight-edge structure of the inclined straight plate 914. Under the reaction force of the elastic member one 915, the toothed plate 912 vibrates longitudinally, thereby driving the lower bearing platform 5 to rotate reciprocally, and the rotation angle changes at all times. The connecting plate 7 moves downward, driving the magnet blocks 931 to move downward. When the magnet blocks 931 move to abut against the partition bevel block 932, under the isolation of the partition bevel block 932, the two groups of magnet blocks 931 are separated. Under the reaction force of the elastic member two 925, the sliding rod 922 returns to its original position.

[0098] As an embodiment of the present invention, a storage box for storing the fragments is placed at the bottom of the detection box body 1.

[0099] The storage box (not shown in the figure) is placed at the bottom of the detection box body 1 for collecting concrete fragments.

[0100] The working principle of the present invention is as follows: In the initial state, the slidably arranged support tube 84 is located at the bottom of the lower bearing platform 5 to support it. The concrete block to be detected is placed on the lower bearing platform 5, and the sealing door 2 is covered. The first telescopic member 3 drives the upper pressing block 4 to press down to perform pressure detection on the concrete block. During the detection process, the pressure data is transmitted to the computer through the controller. After the detection is completed, the first telescopic member 3 moves in the reverse direction, driving the upper pressing block 4 back to the original position. The second telescopic member 6 drives the connecting plate 7 to move upward, and the connecting plate 7 drives the sliding plug rod 81 to move, sucking the gas in the support tube 84 into the fixed cylinder 82, so that the slidably arranged support tube 84 moves away from the lower bearing platform 5. When the slidably arranged support tube 84 moves away from the lower bearing platform 5, the sliding plug rod 81 disengages from the fixed cylinder 82, and the support tube 84 cannot continue to move. The connecting plate 7 continues to move. When the pressing roller 923 abuts against the hypotenuse side of the inclined straight plate 914, the gas inside the connecting cylinder 921 cannot flow out, resulting in the sliding rod 922 being unable to move horizontally, and then driving the inclined straight plate 914 to move upward synchronously. The inclined straight plate 914 drives the toothed plate 912 to move upward, and the toothed plate 912 drives the gear 911 to rotate, thereby driving the lower bearing platform 5 to rotate by a certain angle, causing the fragments on the lower bearing platform 5 to slide and fall. When the inclined straight plate 914 moves to the maximum distance, the pressing roller 923 continues to move upward, and the sliding rod 922 drives the magnet blocks 931 to approach each other, and the second 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 second elastic member 925, the two magnet blocks 931 are adsorbed together. At this time, there is a certain distance between the pressing roller 923 and the straight-edge structure of the inclined straight plate 914. Under the reaction force of the first elastic member 915, the toothed plate 912 undergoes longitudinal jitter, thereby driving the lower bearing platform 5 to rotate reciprocally, and the rotation angle changes at all times. Then the connecting plate 7 moves downward, driving the magnet blocks 931 to move downward. When the magnet blocks 931 move to abut against the separating inclined block 932, under the isolation action of the separating inclined block 932, the two magnet blocks 931 are separated, and under the reaction force of the second elastic member 925, the sliding rod 922 returns to the original position.
