Description

Technical Field

[0001] The present invention relates to the technical field of building detection equipment, and more specifically, to an engineering material detection device. Background Art

[0002] As a kind of engineering material, fire retardant coating is widely used in the construction field. The use of fire retardant coating technology inside and outside buildings has made great contributions to reducing fire losses. At the same time, in order to further improve the performance of fire retardant coatings, research on fire retardant coatings has been ongoing. Among them, the impact cracking behavior of coatings on the surface of steel parts has always been a difficult point in research. Analyzing the damage mechanism of its cracking is crucial to the preparation of alloy coatings with excellent service performance. Furthermore, hollow square steel is a commonly used steel in construction, and impact testing of its surface coating is also necessary.

[0003] When the existing anti-cracking performance testing device performs impact testing on hollow square steel, its impact test method usually evaluates its impact toughness based on the surface and interface observation of the coating sample. The specific operation is to clamp the steel or place it flat on the table, and then use the impact piece to perform impact testing on the upward side of the steel.

[0004] Although the existing anti-cracking performance testing device can complete the testing work well, in actual use, it can only complete the impact test of one side of the hollow square steel at a time. If the impact test is performed by placing it flat on a table, the surface coating of the steel part close to the table is easily damaged, which can easily affect the test result of this side. If the impact test is performed by clamping and fixing the steel part, when adjusting the position of the steel part and performing impact testing on the remaining surfaces of the steel part, the operation is more complicated and time-consuming, and there are certain inconveniences. Summary of the invention

[0005] The present invention provides an engineering material detection device, which solves the technical problem that the existing anti-cracking performance detection device in the related art can only complete the impact detection of one side of the hollow square steel at a time.

[0006] The present invention provides an engineering material detection device, comprising:

[0007] A loading platform with a set height;

[0008] A pair of detection parts arranged opposite to each other, arranged above the table surface of the carrying table;

[0009] A first moving part is mounted on the bearing platform and is used to drive a pair of the detection parts to move away from or approach each other; the first moving part includes a second rotating shaft rotatably connected to the bearing platform, a driving assembly for driving the second rotating shaft to rotate is installed on the bearing platform, the upper end of the second rotating shaft is fixedly connected to a first bevel gear, a casing is fixedly connected to the upper surface of the bearing platform, a pair of second bevel gears arranged opposite to each other are rotatably connected to the casing, each of the second bevel gears is meshed and connected with the first bevel gear, the opposite sides of the two second bevel gears are fixedly connected to a rotating plate, the side of the rotating plate away from the second bevel gear is fixedly connected to a guide rod, the casing is fixedly connected to both sides of the bearing platform along the length direction of the bearing platform, a moving column is slidably connected in each of the transverse plates, the side of the moving column away from the casing is detachably connected to the corresponding detection part, each of the moving columns is fixedly connected to a connecting block, a sliding groove is provided through the transverse plate for the moving column to move, each of the connecting blocks is fixedly connected to a guide plate on the side away from the moving column, a guide groove is provided through the guide plate, and each of the guide rods is penetrated in the corresponding guide groove;

A number of positioning parts 400 corresponding to the detection part 200 are rotatably arranged on the bearing platform 100 and are arranged opposite to the corresponding detection part 200. Each positioning part 400 includes a third rotating shaft 401 rotatably connected to the bearing platform 100. The upper end of the third rotating shaft 401 is fixedly connected to a mounting member, and each mounting member is fixedly connected to a limiting block. The steel piece to be detected is sleeved on the corresponding limiting block. The lower end of each third rotating shaft 401 is fixedly connected to a disk 403, and a plurality of equidistantly arranged grooves 404 are provided on the disk 403. A fixed tube 405 is sleeved on each third rotating shaft 401, and the upper end of the fixed tube 405 is connected to the lower surface of the bearing platform 100. The fixing tube 405 is fixedly connected to a fixing frame 406 at the lower end thereof, and a number of cylinders 407 corresponding to the number of the grooves 404 are fixedly connected to the fixing frame 406, and a positioning rod 408 is slidably arranged in each cylinder 407, and the upper end of the positioning rod 408 is fixedly connected to the inner top of the cylinder 407 through a first spring 409, and the lower end of each positioning rod 408 has a convex portion, and the convex portion is embedded in the corresponding groove 404, and the second movable part 500 is arranged on the lower side of the carrier 100, and the second movable part 500 includes a pair of extrusions, and each extrusion includes a driving rod 501 fixedly mounted on the second rotating shaft 302, wherein one driving rod 501 is located above the other driving rod 501, and the two driving rods 501 are arranged in opposite directions,Each driving rod 501 has a flexible extrusion strip 502 detachably connected to one end away from the second rotating shaft 302. A force-bearing component is installed on each positioning part 400, which cooperates with the corresponding extrusion piece to drive the corresponding positioning part 400 to rotate a set angle. Each force-bearing component includes a number of force-bearing rods 503 corresponding to the number of cylinders 407, and the force-bearing rods 503 are detachably connected to the corresponding disc 403.

[0041] The working principle and beneficial effects of the above technical solution are as follows: first, place the steel part to be inspected on the corresponding positioning part 400, then start the driving assembly on the supporting platform 100 to drive the second rotating shaft 302 to rotate, the second rotating shaft 302 drives the first bevel gear 306 at its upper end to rotate, and then drives the two second bevel gears 308 on the sleeve 307 to rotate in the opposite direction, the second bevel gear 308 drives the corresponding rotating plate 309 to rotate, and then drives the guide rod 310 on the rotating plate 309 to perform circular motion synchronously with the corresponding second bevel gear 308, the guide rod 310 slides back and forth in the guide plate 314, driving the guide plate 314 to move, the guide plate 314 drives the moving column 312 to slide back and forth in the cross plate 311 through the connecting block 313, and then drives the two detection parts 200 to move away from or close to each other, completing the impact detection work of the steel part to be inspected.

[0042] During the test, the second rotating shaft 302 rotates, driving the two driving rods 501 to rotate synchronously. The end of the driving rod 501 located at the top away from the second rotating shaft 302 contacts and squeezes the force-bearing rod 503 on the disk 403 located on the left side of the second rotating shaft 302, thereby driving the disk 403 to rotate, so that the convex parts of the multiple positioning rods 408 all slide out of the corresponding grooves 404, the first spring 409 is compressed, and the driving rod 501 continues to rotate. Due to its limited length, it disengages from the force-bearing rod 503 after rotating at a set angle. At this time, the flexible squeezing strip 502 contacts and squeezes the corresponding force-bearing rod 503. At this time, the convex parts of the disk 403 and the positioning rod 408 are in point contact, and the friction between the two is small, which is not enough to cause the flexible squeezing strip 502 to bend. The extrusion strip 502 can continue to drive the disk 403 to rotate. After the convex parts of the multiple positioning rods 408 move into the groove 404 adjacent to the original groove 404 and are embedded therein under the elastic force of the first spring 409, the resistance of the positioning rod 408 to the disk 403 suddenly increases, and the flexible extrusion strip 502 bends until it is separated from the contacting force-bearing rod 503. Similarly, when the flexible extrusion strip 502 continues to rotate until it contacts the cylinder 407 on another disk 403, the positioning rod 408 on the disk 403 has a greater resistance to the disk 403, causing the flexible extrusion strip 502 to bend and pass smoothly. This cycle is repeated, and the disk 403 located on the left side of the second rotating shaft 302 can be intermittently driven to rotate according to the set angle.

[0043] This embodiment adopts a technical means of cooperating the first movable part 300 and the second movable part 500. While the first movable part 300 drives the detection part 200 to perform impact detection on the steel workpiece to be detected, the second movable part 500, driven by the first movable part 300, drives the steel workpiece to be detected to rotate to the next side every time the detection part 200 completes the impact detection of one side, thereby overcoming the shortcomings of the prior art and achieving the technical effect of improving the detection efficiency of the device.

[0044] This embodiment also adopts technical means of cooperating with the first moving part 300 and the detection part 200. The first moving part 300 can simultaneously drive the two detection parts 200 to perform the detection process, so that the device can complete the detection work of two steel parts to be detected at a time, further improving the detection efficiency.

[0046] The working principle and beneficial effects of the above technical solution are as follows: when the two detection blocks 201 move away from each other, the detection protrusion 202 on each detection block 201 collides with the steel part to be detected on the corresponding side, and impact detection is performed on the surface of the side opposite to the adjacent detection block 201.

[0047] In a specific embodiment: the driving component includes a first rotating shaft 301 rotatably connected to the supporting platform 100, and the first rotating shaft 301 and the second rotating shaft 302 are located on the shaft body on the lower side of the supporting platform 100, and are fixedly connected with synchronous wheels 303. The two synchronous wheels 303 are driven by a synchronous belt 304. A servo motor 305 is fixedly connected to the supporting platform 100, and the output shaft of the servo motor 305 is fixedly connected to the first rotating shaft 301.

[0048] The working principle and beneficial effects of the above technical solution are as follows: when detection is required, the servo motor 305 is started, and the output shaft of the servo motor 305 rotates, driving the first rotating shaft 301 to rotate synchronously. Under the transmission cooperation of the synchronous wheel 303 and the synchronous belt 304, the first rotating shaft 301 drives the second rotating shaft 302 to rotate together, and the second rotating shaft 302 drives the first bevel gear 306 at its upper end to rotate, thereby driving the two second bevel gears 308 on the sleeve 307 to rotate in the opposite direction, and the second bevel gear 308 drives the corresponding rotating plate 309 to rotate, thereby driving the guide rod 310 on the rotating plate 309 to perform circular motion synchronously with the corresponding second bevel gear 308, and the guide rod 310 slides back and forth in the guide plate 314, driving the guide plate 314 to move, and the guide plate 314 drives the moving column 312 to slide back and forth in the cross plate 311 through the connecting block 313, thereby driving the two detection parts 200 to move away from or close to each other, thereby completing the impact detection work of the steel parts to be detected.

[0049] See also Figure 7-8 In a specific embodiment: the force rod 503 on one of the disks 403 is installed on its upper side, cooperating with the extrusion member located above, and is used to drive the disk 403 located on the left side of the second rotating shaft 302 to rotate a set angle, and the force rod 503 on the other disk 403 is installed on its lower side, cooperating with the extrusion member located below, and is used to drive the disk 403 located on the right side of the second rotating shaft 302 to rotate a set angle.

[0050] The working principle and beneficial effects of the above technical solution are as follows: the second rotating shaft 302 rotates, driving the two driving rods 501 to rotate synchronously, and the end of the driving rod 501 located at the top away from the second rotating shaft 302 contacts and squeezes the force-bearing rod 503 on the disk 403 located on the left side of the second rotating shaft 302, thereby driving the disk 403 to rotate, so that the convex parts of the multiple positioning rods 408 all slide out of the corresponding grooves 404, the first spring 409 is compressed, and the driving rod 501 continues to rotate. Due to its limited length, it disengages from the force-bearing rod 503 after rotating at a set angle. At this time, the flexible extrusion strip 502 contacts and squeezes the corresponding force-bearing rod 503. At this time, the convex parts of the disk 403 and the positioning rod 408 are in point contact, and the friction between the two is small, which is not enough to cause the flexible extrusion strip 502 to bend. The flexible extrusion strip 502 can continue to drive the disk 403 to rotate, and wait until the convex parts of the multiple positioning rods 408 move to the original grooves. When the spring 409 is pressed against the stopper 408, the spring 409 is pressed against the stopper 408, and the spring 409 is pressed against the stopper 408. When the spring 409 is pressed against the stopper 408, the spring 409 is pressed against the stopper 408, and the spring 409 is pressed against the stopper 408.

The installation method is simple and quick, and at the same time, it can effectively avoid adverse effects on other surfaces to be inspected during impact detection. Every time the positioning part 400 rotates a quarter of a circle, the switching between the inspected surface and the adjacent surface of the four-corner steel pipe can be completed.

[0061] Working principle:

[0062] First, the steel piece to be inspected is sleeved on the corresponding limit block, and then the servo motor 305 is started. The output shaft of the servo motor 305 rotates, driving the first rotating shaft 301 to rotate synchronously. Under the transmission cooperation of the synchronous wheel 303 and the synchronous belt 304, the first rotating shaft 301 drives the second rotating shaft 302 to rotate together, and the second rotating shaft 302 drives the first bevel gear 306 at its upper end to rotate, thereby driving the two second bevel gears 308 on the sleeve shell 307 to rotate in the opposite direction. The second bevel gear 308 drives the corresponding rotating plate 309 to rotate, thereby driving the guide rod 310 on the rotating plate 309 to perform circular motion synchronously with the corresponding second bevel gear 308, and the guide rod 310 slides back and forth in the guide plate 314, driving the guide plate 314 to move, and the guide plate 314 drives the moving column 312 to slide back and forth in the cross plate 311 through the connecting block 313, thereby driving the two detection parts 200 to move away from or close to each other, thereby completing the impact detection work of the steel piece to be inspected.

[0063] At the same time, the second rotating shaft 302 rotates, driving the two driving rods 501 to rotate synchronously, and the end of the driving rod 501 located at the top away from the second rotating shaft 302 contacts and squeezes the force-bearing rod 503 on the disk 403 located on the left side of the second rotating shaft 302, so that the convex parts of the multiple positioning rods 408 all slide out of the corresponding grooves 404, the first spring 409 is compressed, and the driving rod 501 continues to rotate. Due to its limited length, it is separated from the force-bearing rod 503 after rotating at a set angle. At this time, the flexible extrusion strip 502 contacts and squeezes the corresponding force-bearing rod 503. At this time, the disk 40 3 and the convex part of the positioning rod 408, the friction force between the two is small, which is not enough to bend the flexible extrusion strip 502, and the flexible extrusion strip 502 can continue to drive the disk 403 to rotate. After the convex parts of the multiple positioning rods 408 move to the groove 404 adjacent to the original groove 404 and are embedded therein under the elastic force of the first spring 409, the resistance of the positioning rod 408 to the disk 403 suddenly increases, and the flexible extrusion strip 502 bends until it is separated from the contacting force rod 503. This cycle is repeated, and the disk 403 can be intermittently driven to rotate at a specified angle.

[0064] The disc 403 rotates, causing the convex parts of the multiple positioning rods 408 to slide out of the corresponding grooves 404, and the first spring 409 is compressed. At the same time, the rotation of the disc 403 drives the third rotating shaft 401 to rotate synchronously, and then drives the mounting part and the limit block on the third rotating shaft 401 to rotate synchronously. When the steel part to be inspected on the limit block rotates to a position where the next side is directly opposite to the detection part 200, the convex parts of the multiple positioning rods 408 just move to the groove 404 adjacent to the original groove 404, and are embedded therein under the elastic force of the first spring 409, locking the disc 403 relative to the fixing frame 406, thereby improving the stability of the limit block and facilitating the next round of detection. This cycle is repeated to complete the detection of multiple surfaces in turn.

[0065] The above describes an embodiment of the present invention, but this embodiment is not limited to the above specific implementation methods. The above specific implementation methods are merely illustrative and not restrictive. Under the guidance of this embodiment, ordinary technicians in this field can also make many forms, all of which are protected by this embodiment.
