Description

Technical Field

[0001] The invention relates to the technical field of residual magnetism detection of building materials, in particular to a residual magnetism detection device for building materials. Background Art

[0002] Residual magnetism detection can help determine the magnetic properties of building materials, which is very critical in some special application scenarios. For example, some engineering projects need to ensure that the materials used do not have too high residual magnetism to avoid possible electromagnetic interference or safety problems. If the building materials have high residual magnetism, they may cause electromagnetic interference to nearby electronic equipment and affect the normal operation of the equipment. Therefore, residual magnetism detection can ensure that the building materials will not have adverse effects on electronic equipment.

[0003] At present, when detecting the residual magnetism of bagged stones, the bagged stones are generally transported to the residual magnetism detection station by a conveyor belt, and the probe of a fluxgate magnetometer or other residual magnetism detection instrument is used to contact the bagged stones. By moving the probe in different positions of the bagged stones, multiple groups of different residual magnetism values ​​are measured, and then the multiple groups of values ​​can be integrated to calculate the residual magnetism average value, which can reflect the overall residual magnetism of the bagged stones to a certain extent.

[0004] During the residual magnetism detection process, although the top surface of the bagged stones can be detected by the probe, the surface of the bagged stones in contact with the conveying bag is not easy to contact with the probe. Therefore, the residual magnetism result obtained by the detection calculation is relatively one-sided. As a result, in order to detect the residual magnetism of the bagged stones close to the conveying bag surface, it is convenient to manually turn the bagged stones over and then pass through the detection probe of the detection station for a second time, which requires a large thermal input and the efficiency of residual magnetism detection is poor.

[0005] Research has found that although the above-mentioned residual magnetism detection method can detect the top and bottom surfaces of bagged stones, it cannot perform residual magnetism detection on the inside of the bagged stones, resulting in the above-mentioned residual magnetism detection results being still not accurate enough. In addition, during the residual magnetism detection process, it cannot overcome the influence of humidity on the residual magnetism detection results, and is not conducive to eliminating bagged stones with excessive residual magnetism detection results. Summary of the invention

[0006] The object of the present invention is to provide a residual magnetism detection device for building materials to solve the problems raised in the above background technology.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0009] Furthermore, a slide fixedly connected to the arc rod is rollingly clamped on the outer side of the arc rail, a crossbeam fixedly connected to a plurality of electric push rods 2 is fixed at one end of the arc rod, a laser rangefinder is fixed at the output end of the electric push rods 2, and a plurality of arc through holes are opened on the outer sides of the first and second container boxes.

[0010] Furthermore, two heaters are fixed between the two support columns 2, and mesh holes are provided at one end of the first container box and the second container box.

[0011] Furthermore, two connecting rods 1 are fixed to the discharge end of the conveyor belt 1, and a baffle 1 is fixed between the two connecting rods 1 and at the bottom of the discharge end of the conveyor belt 1.

[0012] Furthermore, a hemispherical block is fixed at one end of the second detection probe, a transmission seat screwed with the screw is fixed at one end of the shaft, and the transmission seat is slidably connected with the guide frame.

[0013] Furthermore, a motor 1 for driving the support shaft to rotate is fixed on the outer side of the V-shaped frame, a support wheel fixedly connected to the L-shaped block is fixed on the outer side of the support shaft, a connecting rod 2 is fixed in the middle of the V-shaped frame, and two baffles 2 are fixed between the two connecting rods 2.

[0014] Furthermore, a U-shaped groove for slidably connecting the second storage box is formed in the top surface of the first storage box, and electric push rods I for driving the movement of the second storage box are fixed near the four corner positions on the outer side of the first storage box.

[0015] Furthermore, a second motor for driving the rotation of the lead screw is fixed at one end of the guide frame. A speed reducer is fixed at one end of the second motor. The second motor is a double-shaft motor, and the other output end of the second motor is fixedly connected to the input end of the speed reducer.

[0016] Furthermore, a transmission shaft is fixed on the top surface of the carrier plate. A transmission mechanism for driving the movement of the arc-shaped rod is arranged between the transmission shaft and the speed reducer. The transmission mechanism includes a transmission rod fixedly connected to the arc-shaped rod and a connecting shaft rotatably connected to the carrier plate. A sleeve rotatably connected to the transmission shaft is fixed at one end of the transmission rod. The sleeve and the connecting shaft are connected by a synchronous belt, and the connecting shaft is meshed and driven with the output end of the speed reducer.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. The bagged stones are conveyed between the first storage box and the second storage box through the first conveyor belt. The first storage box and the second storage box rotate to the position between the two arc-shaped rails on the support shaft of the bracket. The second motor drives the lead screw to rotate, so that the shaft rod screwed with the lead screw drives the detection probe II to squeeze the packaging bag from a corner position of the bagged stones and insert into the inside of one end of the packaging bag. The detection probe II at the end of the shaft rod performs residual magnetic detection on the inside of the bagged stones. At the same time, the output end of the second motor drives the transmission mechanism to operate through the speed reducer. The transmission mechanism drives the transmission rod to rotate along the transmission shaft, so that the sliding table drives the arc-shaped rod to move along the arc-shaped rail towards the bagged stones. Multiple detection probes II at the end of the arc-shaped rod move through the arc-shaped through holes on the surface of the bagged stones. The detection probe II performs residual magnetic detection on the outside of the bagged stones. Combining the internal residual magnetic detection and the external residual magnetic detection of the bagged stones is beneficial to improving the accuracy of the detection results compared with only performing residual magnetic detection on the outside of the bagged stones.

[0019] 2. By arranging two detection mechanisms on one detection module, multiple detection probes I on the two detection mechanisms respectively perform residual magnetic detection on the top surface and the bottom surface of the bagged stones, and two detection probes II on the two detection mechanisms respectively perform residual magnetic detection on the two corner internal positions at one end of the bagged stones, so as to realize the residual magnetic detection on the top surface and the bottom surface at one end of the bagged stones and the residual magnetic detection on the inside of the other end of the bagged stones, which is convenient for initially detecting the residual magnetism of the bagged stones in all directions.

[0020] The bracket is used to rotate the first and second containing boxes counterclockwise by 90 degrees so that the bagged stones that have been initially detected by residual magnetism are switched to the vertical direction. The first and second containing boxes move away from each other to release the bagged stones to another containing mechanism near the middle of the support column. The containing mechanism continues to rotate counterclockwise by 90 degrees so that the bagged stones that have been initially detected by residual magnetism are switched to the detection module near the middle of the support column. After the bagged stones have been switched by 90 degrees twice, the undetected positions on the top and bottom surfaces of one end of the bagged stones are in the detection position of the detection probe one, and the undetected position inside one end of the bagged stones is in the detection position of the detection probe two. Similarly, the two detection mechanisms on the other detection module can perform secondary residual magnetism detection on the undetected areas on the bagged stones, thereby realizing all-round residual magnetism detection on the top and bottom surfaces of the bagged stones and the internal positions of the four corners of the bagged stones, and the residual magnetism content estimated by multiple sets of detection values ​​is more representative.

[0021] 3. By fixing two heaters between the two support columns, the air outlet of each heater is facing the open end of the horizontal container box one and the container box two. During the preliminary residual magnetism detection or the secondary residual magnetism detection, in order to exclude the possibility that the detection result is too small due to moisture in the packaging bag (when the humidity is too high, the magnetic material is easily magnetized, forming hysteresis), the bagged stones that have not been detected by residual magnetism can be first replaced to a position facing the heater, so that the warm air passes through the open ends of the container box one and the container box two, and then flows out from the arc-shaped through holes and mesh positions of the air container box one and the container box two, so as to facilitate the pre-drying of the bagged stones. After drying, the bagged stones can be rotated and replaced to the detection mechanism station for residual magnetism detection again, which can eliminate the influence of moisture on the small detection result to a certain extent and further improve the accuracy of the detection result.

[0022] 4. The bracket can be used to reposition the containing mechanism in different directions after residual magnetism detection. For example, bagged stones with qualified test results can be released onto conveyor belt 2 with the help of the bracket and the containing mechanism for transportation. Bagged stones with unqualified test results can be released to the ground at one end of conveyor belt 2 with the help of the bracket and the containing mechanism, so as to eliminate bagged stones with high residual magnetism content.

[0023] 5. By rotating the first and second containing boxes to a horizontal position for residual magnetism detection, the gravity of the bagged stones in a horizontal state is applied to the first containing box, which makes it convenient for the shaft rod with the detection probe 2 to be inserted into the bagged stones. A vibration motor can be installed inside the transmission seat at one end of the shaft rod so that the shaft rod can vibrate and be easily inserted into the bagged stones. The top and bottom surfaces of the bagged stones in a horizontal state are both flat, which makes it convenient for multiple detection probes to detect a large flat area. The detection probe 1 is installed at the output end of the second electric push rod. When the detection probe 2 moves to detect the position, if some of the bagged stones are raised, the output end of the second electric push rod can be retracted to prevent the raised position from hindering the movement of the detection probe 2, and also to prevent the detection probe 2 from scratching the raised stone position, which is beneficial to protecting the detection probe 1.

Specific implementation mode

[0036] 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 creative efforts shall fall within the protection scope of the present invention.

[0037] Example 1, please refer to Figures 1 to 11In an embodiment of the present invention, a residual magnetism detection device for building materials includes a support column 100 and two support columns 200, a conveyor belt 1 210 and a conveyor belt 220 for conveying bagged stones are fixed between the tops and bottoms of the two support columns 200, respectively, two brackets 300 are fixed between the support column 100 and the two support columns 200, the bracket 300 includes two V-shaped frames 310, a support shaft 320 is rotatably connected between the two V-shaped frames 310, a plurality of L-shaped blocks 330 are evenly fixed on the outer side of the support shaft 320, a containing mechanism 400 for containing bagged stones is fixed at one end of the L-shaped block 330, the containing mechanism 400 includes two containing boxes 1 410 and two containing boxes 2 420 that are slidably connected to each other, the middle and top of the support column 100 are fixed A detection module for detecting the residual magnetism of bagged stones is provided, the detection module includes a carrier plate 110 fixedly connected to a support column 100, detection mechanisms 500 are arranged at both ends of the top surface of the carrier plate 110, the detection mechanism 500 includes an arc rail 510 and a guide frame 520, an arc rod 530 is slidably engaged with the outer side of the arc rail 510, a plurality of electric push rods 540 are fixed to one end of the arc rod 530, a detection probe 1 541 is fixed to the output end of the electric push rod 2 540, a screw rod 550 is rotatably connected to the inner side of the guide frame 520, a shaft rod 560 is screwed and connected to the outer side of the screw rod 550, a detection probe 2 561 is fixed to one end of the shaft rod 560, a fluxgate magnetometer is fixedly installed on the bottom surface of the carrier plate 110, and the detection probe 1 541 and the detection probe 2 561 are both electrically connected to the fluxgate magnetometer.

[0038] Specifically, the bagged stones are put into the containing mechanism 400 through the conveyor belt 210, and the containing mechanism 400 rotates on the bracket 300 to transfer the bagged stones to the position of the detection mechanism 500, and the screw rod 550 rotates to drive the shaft rod 560 with the detection probe 2 561 to be inserted into the inside of the bagged stones for detection, and at the same time, the arc rod 530 moves along the arc rail 510 to make multiple detection probes 541 pass through the top and bottom surfaces of the bagged stones, thereby realizing residual magnetism detection of the top and bottom surfaces and the interior of the bagged stones, and by arranging two detection modules, the detection mechanism 500 on each detection module can respectively detect the internal position of different ends of the bagged stones and the top and bottom surface positions, thereby realizing all-round residual magnetism detection of the top and bottom surfaces of the bagged stones and the internal positions of the four corners of the bagged stones, and the residual magnetism content estimated by multiple groups of detection values ​​is more representative.

[0039] The present application can install a suitable number of fluxgate magnetometers on the carrier 110, and then connect the fluxgate magnetometers with detection probes at corresponding positions, including detection probe 1 541 and detection probe 2 561, to simultaneously detect the residual magnetism of different positions of the bagged stones. The technology of using the fluxgate magnetometer to cooperate with the detection probe to detect the residual magnetism is the prior art, and the specific principle of detecting the residual magnetism is not elaborated here. As for the power supply problem of the containing mechanism 400 rotating on the bracket 300, the electric slip ring of the prior art can be sleeved on the support shaft 320 of the bracket 300, and the electric push rod 1 430 on the containing mechanism 400 is powered by the electric slip ring and the wire. The electric slip ring power supply is the prior art, and the specific working principle is not elaborated here.

[0040] like Figure 4 , Figure 7 and Figure 8 As shown, in this embodiment, the outer side of the arc rail 510 is rollingly clamped with a slide 511 fixedly connected to the arc rod 530, one end of the arc rod 530 is fixed with a crossbeam 531 plugged and fixed with multiple electric push rods 540, the output end of the electric push rods 540 is fixed with a laser rangefinder, and multiple arc through holes 440 are opened on the outer sides of the container box 1 410 and the container box 2 420.

[0041] In this embodiment, the slide 511 is rollingly engaged with the arc rail 510, and can move to different positions along the arc rail 510 with the arc rod 530, wherein the slide 511 and the arc rail 510 are components for moving an arc track in the prior art, and the distance between the ends of the two arc rails 510 is greater than the width of the container box 410, so that the container box 410 can smoothly pass through the detection mechanism 500. In this application, the arc center of the arc rod 530, the arc rail 510 and the arc through hole 440 are all the same, so that multiple detection probes 541 can rotate around the transmission shaft 111 to detect at different positions, and the laser rangefinder can measure the electric push rod 2 The distance between the output end 540 and the bagged stones, when this distance is the same as the length of the detection probe 541, it means that the bottom end of the detection probe 541 is in contact with the bagged stones. When the distance value is different from the length of the detection probe 541, the detection probe 541 can be made to contact with the bagged stones by adjusting the extension or shortening of the output end of the electric push rod 540 to prevent the detection probe 541 from being squeezed by the bagged stones and affecting the smooth movement position of the detection probe 541. A fixed block 113 fixedly connected to the arc rail 510 is fixed on the carrier plate 110, and a fixed block 2 114 fixedly connected to the guide frame 520 is fixed on the carrier plate 110.

[0042] like Figure 2 and Figure 3As shown, in this embodiment, two connecting rods one 211 are fixed to the discharge end of the conveyor belt one 210, and baffles one 212 are fixed between the two connecting rods one 211 and at the bottom of the discharge end of the conveyor belt one 210. The two obliquely arranged baffles one 212 can accurately drop the bagged stones into the vertical position in the receiving boxes one 410 and two 420.

[0043] As Fig. 9 and Fig.10 As shown, in this embodiment, a hemispherical block 5611 is fixed to one end of the detection probe two 561, and a transmission seat screwed to the lead screw 550 is fixed to one end of the shaft rod 560. The transmission seat is slidably connected to the guide frame 520.

[0044] In this embodiment, the hemispherical block 5611 enables the end of the shaft rod 560 to carry the detection probe two 561 and smoothly enter the interior of the bagged stones. When the lead screw 550 rotates, the transmission seat moves along the lead screw 550 in a screwed manner, and then the shaft rod 560 drives the detection probe two 561 to enter the interior of the bagged stones.

[0045] As Figure 5 As shown, in this embodiment, a motor one 311 for driving the support shaft 320 to rotate is fixed to the outside of a V-shaped frame 310. A support wheel fixedly connected to the L-shaped block 330 is fixed to the outside of the support shaft 320. A connecting rod two 312 is fixed to the middle of the V-shaped frame 310, and two baffles two 3121 are fixed between the two connecting rods two 312.

[0046] In this embodiment, the motor one 311 drives the support shaft 320 to rotate so that multiple receiving mechanisms 400 can rotate and be adjusted to different positions. The two obliquely arranged baffles two 3121 can make the bagged stones move between the two vertically arranged receiving mechanisms 400.

[0047] As Figure 4 and Figure 7 As shown, in this embodiment, a U-shaped groove 411 for slidably connecting with the receiving box two 420 is opened on the top surface of the receiving box one 410. Electric push rods one 430 for driving the receiving box two 420 to move are fixed near the four corner positions on the outside of the receiving box one 410.

[0048] In this embodiment, when it is necessary to move the bagged gravel on the bracket 300, the first electric push rod 430 contracts in length to make the first holding box 410 and the second holding box 420 approach each other, that is, the second holding box 420 slides into the C-shaped groove 411 of the first holding box 410. The first holding box 410 and the second holding box 420 clamp and fix the bagged gravel to prevent the bagged gravel from falling. When it is necessary to release the bagged gravel, the output end of the first electric push rod 430 extends to enable the first holding box 410 and the second holding box 420 to move away from each other, causing the bagged gravel to fall. Spherical protrusions are fixed on the inner sides of the first holding box 410 and the second holding box 420, so that the bagged gravel is clamped more firmly when the two holding boxes clamp it.

[0049] During specific implementation, the external conveyor belt 210 conveys the bagged gravel to the position between the first holding box 410 and the second holding box 420 of the holding mechanism 400 at the top of the first support column 100. The first motor 311 drives the support shaft 320 to rotate counterclockwise by 90 degrees (the rotation direction refers to the instruction manual Figure 2 ) so that the two holding boxes clamp and convey the bagged gravel to the position of the detection mechanism 500 at the top of the first support column 100. The second motor 551 drives the lead screw 550 to rotate, and the shaft rod 560 drives the second detection probe 561 to move into the packaging while detecting the residual magnetism inside the packaging from the corner position of the bagged gravel (refer to the instruction manual Figure 8 ). The first motor 311 operates by driving the reducer 5511. Under the transmission action of the transmission mechanism 600, the transmission rod 610 drives the arc rod 530 to move. The arc rod 530 drives a plurality of first detection probes 541 to move on the surface of the bagged gravel to detect the residual magnetism. Then, the two holding boxes drive the bagged gravel with preliminary residual magnetism detection to rotate counterclockwise by 90 degrees, and release the bagged gravel onto the holding mechanism 400 at the middle position of the first support column 100. Similarly, the two holding boxes on this holding mechanism 400 transfer the bagged gravel to the detection mechanism 500 of another detection module for detection. The secondary detection mainly supplements the detection of the areas on the bagged gravel that have not been detected. Finally, the multiple groups of residual magnetism values obtained from the detection are statistically analyzed to calculate the average residual magnetism value. Finally, the holding mechanism 400 releases and rejects the bagged gravel with a larger residual magnetism detection value from one end of the conveyor belt 220, and releases the bagged gravel with a qualified residual magnetism detection value onto the conveyor belt 220 for conveying out.

[0050] Embodiment 2: On the basis of Embodiment 1, in order to make the arc rod 530 and the shaft rod 560 on the two detection mechanisms 500 be driven by the second motor 551.

[0051] As Figure 8 、 Fig. 9 and Fig.11As shown, in this embodiment, a second motor 551 for driving the screw rod 550 to rotate is fixed at one end of the guide frame 520, a reducer 5511 is fixed at one end of the motor 551, the motor 551 is a dual-axis motor, and the other output end of the motor 551 is fixedly connected to the input end of the reducer 5511, a transmission shaft 111 is fixed to the top surface of the carrier plate 110, and a transmission mechanism 600 for driving the arc rod 530 to move is arranged between the transmission shaft 111 and the reducer 5511, the transmission mechanism 600 includes a transmission rod 610 fixedly connected to the arc rod 530 and a connecting shaft 630 rotatably connected to the carrier plate 110, a sleeve 620 rotatably connected to the transmission shaft 111 is fixed at one end of the transmission rod 610, the sleeve 620 and the connecting shaft 630 are connected by synchronous belt transmission, and the connecting shaft 630 is meshed with the output end of the reducer 5511 for transmission.

[0052] In this embodiment, motor 2 551 rotates screw rod 550 so that screw rod 550 rotates with transmission seat, and transmission seat moves with shaft rod 560. Shaft rod 560 moves and detects with detection probe 2 561 toward the inside of bagged stones. The other output end of motor 2 551 operates with reducer 5511. The output end of reducer 5511 rotates with connecting shaft 630 through two bevel gears meshing with each other. Connecting shaft 630 rotates with the synchronous pulley on its top. Under the transmission action of the synchronous belt, the synchronous pulley on support rod 112 rotates with sleeve 620, and sleeve 620 rotates with transmission rod 610. Transmission rod 610 drives slide 511 to move. Slide 511 moves with detection probe 1 541 on arc rod 530 to detect residual magnetism on the surface of bagged stones.

[0053] Embodiment 3, based on embodiment 1, is to eliminate the influence of moisture on the residual magnetism detection of bagged stones.

[0054] like Figure 1 and Figure 2 As shown, in this embodiment, two heaters 230 are fixed between the two supporting columns 200 , and mesh holes 450 are provided at one end of the first container box 410 and the second container box 420 .

[0055] In this embodiment, the heater 230 can blow air toward the horizontally positioned container box 1 410 and container box 2 420, so that the bagged stones to be tested for residual magnetism can be rotated to the position of the heater 230 for drying first, thereby preventing the packaging bags from being damp and causing the residual magnetism test results to be too small. The arc-shaped through holes 440 and the mesh holes 450 on the container boxes can allow air to circulate inside the container boxes, thereby improving the drying efficiency.
