[0016] Compared with the prior art, the present invention provides a concrete solidification strength detection device and a detection method for house safety, which have the following beneficial effects: 1. A concrete solidification strength detection device and a detection method for house safety, wherein a driving source drives the rotation of a load-bearing plate, so that when one end of the load-bearing plate rotates upward, a movable plate moves outward, thereby removing debris stuck to the bottom of a die through a scraper, and at the same time, after the load-bearing plate rotates half a circle, the debris on the load-bearing plate is removed by gravity, and at the same time, the debris on the elastic cloth is shaken and removed by repeatedly stretching and relaxing the elastic cloth, thereby ensuring the cleanliness of the bottom of the die and the surface of the elastic cloth, and solving the problem that the debris on the work surface and the die will produce different pressures on the material surface, thereby causing inaccurate detection of its physical and mechanical properties.

[0017] 2. A concrete solidification strength detection device and a detection method for house safety. Through the setting of the second reciprocating screw, after the load-bearing plate rotates half a circle, the object to be detected falls into the cabinet due to gravity, and at the same time, the movable baffle is no longer resisted by the object to be detected, so it moves back and forth synchronously on the load-bearing plate, so that the elastic cloth between the four movable baffles repeatedly relaxes and shakes, so that the debris on the surface of the elastic cloth is cleared by itself, preventing the debris from affecting the detection result of the device.

[0018] 3. A concrete solidification strength detection device and a detection method for house safety. Through the setting of a second reciprocating screw and a movable baffle, after the device completes the detection of the object to be detected, the second reciprocating screw drives the movable baffle to move in opposite directions, so that the movable baffle fixes the object to be detected, preventing the object to be detected and debris on the surface of the load-bearing plate from moving downward during the rotation of the load-bearing plate, causing the object to be detected to collide with the testing machine on one side of the press.

DETAILED DESCRIPTION

[0021] 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.

[0022] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a concrete solidification strength detection device and a detection method for house safety.

[0023] For example, see Figure 1-Figure 2 A concrete solidification strength detection device comprises a cabinet 1, a press 2 arranged on one side of the top of the cabinet 1, and a testing machine 3, the press 2 comprises a frame 21, a driving cylinder 22 and a die 23, a through hole 4 is opened on the top of the cabinet 1, a load-bearing plate 5 is installed on the top of the inner cavity of the through hole 4, a driving source 6 is fixedly installed on one side of the cabinet 1, driving the load-bearing plate 5 to rotate, a positioning component 7 is arranged on the load-bearing plate 5, scraping components 8 are arranged on both sides of the load-bearing plate 5, and a transmission member 9 is arranged between the scraping component 8 and the positioning component 7; The positioning assembly 7 includes four movable baffles 71 and an elastic cloth 72. The elastic cloth 72 is fixedly installed between the four movable baffles 71 and fits the top surface of the load-bearing plate 5. The driving source 6 drives the load-bearing plate 5 to rotate, so that when the top of the load-bearing plate 5 rotates toward the inside of the cabinet 1, the transmission member 9 runs, driving the four movable baffles 71 to move toward each other at the same time, so that the detection object is located between the four movable baffles 71. When the detection object falls into the cabinet 1, the four movable baffles 71 repeatedly move toward each other, and the repeated movement drives the elastic cloth 72 to repeatedly relax and shake; The scraping assembly 8 includes two movable plates 81 and two scrapers 82. The driving source 6 drives the load-bearing plate 5 to rotate, so that when the top side of the load-bearing plate 5 rotates upward, the transmission member 9 runs, driving the movable plates 81 on both sides of the load-bearing plate 5 to move outward, and scrapes the residue at the bottom of the mold 23 through the scraper 82.

[0024] Specifically, the object to be tested is placed on the load-bearing plate 5, and then the die 23 is driven by the driving cylinder 22 to test the solidification strength of the object to be tested. At the same time, the maximum load borne by the object to be tested is recorded by the testing machine 3. After the recording is completed, the die 23 is reset by the driving cylinder 22, and then the transmission member 9 is driven by the driving source 6 to operate. The transmission member 9 operates to drive the load-bearing plate 5 to rotate. During the rotation of the load-bearing plate 5, the transmission member 9 drives the moving plates 81 on both sides of the load-bearing plate 5 to move in reverse. When the end of the load-bearing plate 5 that rotates upward moves to contact with the die 23, the scraper 82 contacts the bottom of the die 23. The bottom of the die 23 is scraped. At the same time, when the transmission member 9 is running, it drives the four movable baffles 71 to move in opposite directions, so as to squeeze and fix the objects to be detected. When the load-bearing plate 5 rotates half a circle, the objects to be detected in the multiple movable baffles 71 and the debris on the load-bearing plate 5 fall into the cabinet 1 due to gravity, and then the four movable baffles 71 resume movement. During the back-and-forth movement of the four movable baffles 71, the elastic cloth 72 is repeatedly stretched and relaxed and shaken, so that the debris on the surface of the elastic cloth 72 falls into the cabinet 1. When the load-bearing plate 5 rotates one circle, the movable plate 81 and the movable baffle 71 are reset. The load-bearing plate 5 is driven to rotate by the driving source 6, so that when one end of the load-bearing plate 5 rotates upward, the movable plate 81 moves outward, so that the debris stuck to the bottom of the die 23 is cleared by the scraper 82. At the same time, after the load-bearing plate 5 rotates half a circle, the debris on the load-bearing plate 5 is cleared by gravity, and at the same time, the debris on the elastic cloth 72 is shaken and cleared by repeatedly stretching and relaxing the elastic cloth 72, thereby ensuring the cleanliness of the bottom of the die 23 and the surface of the elastic cloth 72, and solving the problem that the debris on the work surface and the die 23 will produce different pressures on the material surface, thereby causing inaccurate detection of its physical and mechanical properties.

A first torsion spring 86 is installed at the hinge between the scraper 82 and the moving plate 81, so that when the transmission member 9 drives the scraper 82 to rotate upward to the bottom side of the die 23, the scraper 82 contacts the bottom of the die 23, and the scraper 82 rotates, and the first torsion spring 86 is squeezed; The transmission member 9 includes an inner gear 91 and an outer gear ring 92.

The bottom surface is in contact. During the continuous rotation of the load-bearing plate 5, the scraper plate 82 and the movable plate 81 are hinged, so that the scraper plate 82 and the movable plate 81 rotate, and the first torsion spring 86 is deformed. When the scraper plate 82 finishes scraping the bottom of the die 23, the scraper plate 82 is no longer in contact with the die 23, and the first torsion spring 86 drives the scraper plate 82 to reset, thereby achieving the effect of cleaning the bottom of the die 23 during the cleaning of the inspected items. When the load-bearing plate 5 is rotated from a horizontal state to a vertical state, the movable plate 81 moves to the end of the guide groove 83 and no longer moves outward.

The movable block 028 is assembled on the third reciprocating screw rod 021 through a thread. A tooth plate 029 is fixedly connected in the installation chamber 022. A main rotating rod 0210 is rotatably connected in the movable block 028 through a bearing. A first gear 0211 is fixedly connected to the outer periphery of the main rotating rod 0210. The first gear 0211 is meshed and connected with the tooth plate 029. A movable plate 0212 is fixedly connected to one side of the movable block 028. The slave rotating rod 011 is rotatably arranged at one end of the movable plate 0212 through a bearing. A second transmission belt 0213 is sleeved on the outer periphery of the main rotating rod 0210 and the slave rotating rod 011. Specifically, when the experiment on the load-bearing plate 5 is finished and the load-bearing plate 5 is rotating downward, the first motor 027 is running, driving the third worm 025 to rotate, and the third worm wheel 026 is driven to rotate through the meshing connection between the third worm 025 and the third worm wheel 026, thereby driving the third reciprocating screw 021 to rotate, and the movable block 028 is driven to move up and down through the threaded connection between the third reciprocating screw 021 and the movable block 028.

[0028] Example 5, see Figure 1-Figure 11 This embodiment discloses a detection method for housing safety, and the specific steps are as follows: The concrete block to be concreted is placed on the load-bearing plate 5, and then the pressing die 23 is driven by the driving cylinder 22 to test the setting strength of the concrete block. At the same time, the maximum load borne by the concrete block is recorded by the testing machine 3. After the recording is completed, the pressing die 23 is reset by the driving cylinder 22, and then the transmission member 9 is driven by the driving source 6 to operate. The transmission member 9 operates to drive the load-bearing plate 5 to rotate. During the rotation of the load-bearing plate 5, the transmission member 9 drives the moving plates 81 on both sides of the load-bearing plate 5 to move in reverse. When the end of the load-bearing plate 5 that rotates upward moves to contact with the pressing die 23, the scraper 82 contacts the bottom of the pressing die 23 and The bottom of the die 23 is scraped, and at the same time, when the transmission member 9 is running, it drives the four movable baffles 71 to move towards each other, so as to squeeze and fix the concrete block on all sides. When the load-bearing plate 5 rotates half a circle, the concrete blocks in the multiple movable baffles 71 and the debris on the load-bearing plate 5 fall into the cabinet 1 due to gravity, and then the four movable baffles 71 resume movement. During the back and forth movement of the four movable baffles 71, the elastic cloth 72 is driven to repeatedly relax and shake, so that the debris on the surface of the elastic cloth 72 falls into the cabinet 1. When the load-bearing plate 5 rotates one circle, the movable plate 81 and the movable baffle 71 are both reset.

[0029] Working principle: The servo motor 61 drives the load-bearing plate 5 to rotate, and the meshing connection between the internal gear 91 on one side of the load-bearing plate 5 and the external gear ring 92 on one side of the partition plate 94 makes the load-bearing plate 5 drive the circular rod 95 to rotate during the rotation process, thereby driving the first worm 96 to rotate, and the meshing connection between the first worm 96 and the first worm wheel 97 drives the first worm wheel 97 to rotate, and the first worm wheel 97 is fixedly installed on the middle part of the outer periphery of the cross bar 84 to drive the cross bar 84 to rotate, thereby driving the first reciprocating screw 85 at both ends of the cross bar 84 to rotate, and the threaded connection between the first reciprocating screw 85 and the movable plate 81 drives the movable plate 81 to move in the guide groove 83. When one end of the load-bearing plate 5 rotates to the side of the bottom surface of the die 23, the scraper 82 at one end of the movable plate 81 is in contact with the die 2 3 bottom contact, during the continuous rotation of the load-bearing plate 5, the scraper 82 and the movable plate 81 are hinged, so that the scraper 82 and the movable plate 81 rotate, and the first torsion spring 86 is deformed. When the scraper 82 finishes scraping the bottom of the die 23, the scraper 82 is no longer in contact with the die 23, and the first torsion spring 86 drives the scraper 82 to reset, thereby achieving the effect of cleaning the bottom of the die 23 during the cleaning of the detected objects. When the load-bearing plate 5 rotates from the horizontal state to the vertical state, the movable plate 81 moves to the end of the guide groove 83 and no longer moves outward. When the load-bearing plate 5 moves from the vertical state to the horizontal state, the movable plate 81 is gradually received in the guide groove 83, so that the debris scattered on the surface of the movable plate 81 is pushed and removed through the edge of the load-bearing plate 5; The object to be detected is placed on the elastic cloth 72, and the multiple movable baffles 71 do not contact the object to be detected, so as to prevent the movable baffles 71 from applying pressure on the surrounding of the object to be detected, thereby causing the problem of deviation in the detection result. When the detection of the object to be detected is completed, the servo motor 61 drives the load-bearing plate 5 to rotate, and drives the circular rod 95 to rotate through the meshing connection between the inner gear 91 and the outer gear ring 92, thereby driving the intermediate rod 913 fixedly connected to the circular rod 95 to rotate, and the drive rod 912 is driven to rotate through the arrangement of the transmission belt 914 installed on the intermediate rod 913 and the drive rod 912, and the drive rod 912 is set in the sleeve 915, and the hinge block 901 is in close contact with the stopper 903. The sleeve 915 is configured to rotate, thereby driving the secondary bevel gear 911 to rotate, and then driving the main bevel gear 910 to rotate, and driving the second worm 98 at the top of the main bevel gear 910 to rotate, and through the meshing connection between the second worm 98 and the second worm wheel 99, driving the extension rod to rotate, thereby driving the second reciprocating screw 74 to rotate, and through the threaded connection between the second reciprocating screw 74 and the sliding block 75, driving the multiple moving baffles 71 to move towards each other, so that the multiple moving baffles 71 fix the four sides of the object to be detected, preventing the object to be detected and debris on the surface of the load-bearing plate 5 from moving downward during the rotation of the load-bearing plate 5, so that the problem of the object to be detected causing collision with the testing machine 3 on one side of the press 2 occurs; When the movable baffle 71 contacts the surface of the object to be detected, the movable baffle 71 stops moving, thereby causing the secondary bevel gear 911 and the sleeve 915 on one side to stop rotating. At this time, one side of the bottom of the hinge block 901 is set as an arc surface and is tangent to the outer surface of the driving rod 912, and the other side of the bottom of the hinge block 901 is set as a plane and is in contact with the outer surface of the driving rod 912, so that the hinge block 901 rotates toward the side of the bottom set as the arc surface, so that the hinge block 901 can be separated from the block 903, so that the driving rod 912 can still rotate without rotating the sleeve 915; When the movable plate 81 on the load-bearing plate 5 gradually rotates to the direction close to the inner cavity of the cabinet 1, the objects to be detected between the multiple movable baffles 71 and the debris on the plane of the load-bearing plate 5 fall downward due to the effect of gravity and are collected in the cabinet 1. When there is no obstacle between the multiple movable baffles 71, the driving rod 912 drives the sleeve 915 to rotate, thereby driving the second reciprocating screw 74 to rotate, and making the multiple movable baffles 71 repeatedly move relative to each other, so that the elastic cloth 72 between the multiple movable baffles 71 repeatedly relaxes and shakes, thereby making the debris on the surface of the elastic cloth 72 clear itself, preventing the debris from affecting the detection result of the device. When the load-bearing plate 5 is reset, the multiple movable baffles 71 are reset; When the experiment on the load-bearing plate 5 is finished and it is rotating downward, the first motor 027 is running, driving the third worm 025 to rotate, and the third worm wheel 026 is driven to rotate through the meshing connection between the third worm 025 and the third worm wheel 026, thereby driving the third reciprocating screw 021 to rotate, and the movable block 028 is driven to move up and down through the threaded connection between the third reciprocating screw 021 and the movable block 028. When the movable block 028 moves upward, the first gear 0211 is driven to rotate through the meshing connection between the first gear 0211 on the main rotating rod 0210 inside the movable block 028 and the toothed plate 029, thereby driving the movable block 028 to rotate. The main rotating rod 0210 is driven to rotate, and the second transmission belt 0213 sleeved on the outer periphery of the main rotating rod 0210 and the slave rotating rod 011 is set to drive the slave rotating rod 011 to rotate, thereby driving the cleaning plates 012 at both ends of the slave rotating rod 011 to rotate, and then when the movable plate 0212 moves to the surface of the load-bearing plate 5, the debris on the surface of the load-bearing plate 5 is scraped and cleaned by the cleaning plate 012. When the debris on the surface of the load-bearing plate 5 is cleaned, the threaded connection between the third reciprocating screw 021 and the movable block 028 drives the movable plate 0212 to move downward, so as to avoid collision between the load-bearing plate 5 and the movable plate 0212 when the load-bearing plate 5 rotates.
