[0015] The invention provides a detection device for construction engineering supervision, which has the following beneficial effects:

[0016] 1. Through the bending detection mechanism set up, the material is placed on the top of the gear bar, and then the output end of the second cylinder extends out to the top of the support rod. When the lower top plate descends, it drives the second cylinder to descend. Then the output end of the second cylinder presses the support rod to make the support rod rotate clockwise, and then the buffer box rotates to the round shaft, and then the round shaft rises in the round hole and drives the baffle to rise to open the discharge port. Then the iron ball in the inclined frame is discharged from the discharge port into the interior of the buffer box. The weight of the iron block is three times the weight of the buffer box. Then the output end of the second cylinder retracts. Since the support rod is located at one end of the iron block, the support rod will rotate in the opposite direction to reset at this time, and then the round shaft descends to make the baffle cover the discharge port again. The above operation can realize the cyclic falling of the iron ball. The bending detection mechanism is controlled by the extension and contraction of the second cylinder. When the bending test is not required, the output end of the second cylinder retracts, and the iron ball hits the material in the detection tank after passing through the buffer box, and then the bending change of the material after being compressed is observed to realize the test of its bending performance, so as to detect whether the material meets the specified requirements.

[0017] 2. Through the set fixing mechanism, the material to be tensile tested is sampled and then clamped through the fixing mechanism, and the sampled material is placed inside the two clamps. If the tested material is strip-shaped, it can be directly placed on the plane of the two clamps. If the tested material is round, it can be placed inside the arc groove. Then the output end of the first cylinder extends to drive the cross plate to rise inside the empty groove. When the cross plate rises, it pushes the two clamps to rise. Since the convex block on the back of the clamp is located inside the inclined groove, when the rise is accelerated, the convex block moves upward inside the inclined groove. Since the two inclined grooves are wide at the bottom and narrow at the top, when the convex block moves, the output end of the telescopic rod extends to drive the clamp to move horizontally, and then the distance between the two clamps is shortened and the tested material is clamped and fixed. Then the motor inside the workbench starts to drive the screw to rotate. Since the limit rod passes through the lower top plate, the lower top plate can be prevented from rotating. Therefore, when the screw rotates, it will drive the lower top plate to move downward. The lower top plate descends and drives the bottom clamp seat to descend. Then the tested material is stretched to achieve tensile testing. BRIEF DESCRIPTION OF THE DRAWINGS

The following is an explanation of its embodiments based on the overall structure of the present invention.

[0029] A detection device for construction engineering supervision, comprising: a main body 1 of a universal testing machine, the bottom of the main body 1 is a workbench 8, a limit rod 2 is fixed on the top of the workbench 8, an upper top plate 5 is fixed on the top of the limit rod 2, a screw rod 6 is fixed on the top of the workbench 8, the outer rotation of the screw rod 6 is connected to a lower top plate 7, a fixing mechanism 3 is provided at the bottom of the upper top plate 5 and the top of the lower top plate 7, a bending detection mechanism 4 is provided on one side of the main body 1, and the limit rod 2 penetrates the lower top plate 7 to limit the lower top plate 7 A fan is installed inside the workbench 8, and the fan is used to cool the motor when it is working. A heat dissipation hole cooperating with the fan is provided at the bottom of the workbench 8. A motor is installed inside the workbench 8, and the output end of the motor is fixedly connected to the bottom of the screw rod 6. The motor starts and drives the screw rod 6 to rotate. An operating table 9 is installed on the top of the workbench 8, and the operating table 9 is provided with operating buttons. A first pressure head 11 is fixed on the top of the workbench 8, and a second pressure head 11 is fixed on the bottom of the lower top plate 7.

[0030] Furthermore, the fixing mechanism 3 includes a clamping seat 301, the interior of the clamping seat 301 is provided with a placement groove 302 and a groove 303, the interior of the groove 303 is slidably connected with a telescopic rod 304 in the vertical direction, a clamping block 305 is fixed to one end of the telescopic rod 304, one of the clamping blocks 305 is provided with an arc groove 306, and anti-slip grooves are provided inside the arc groove 306, the number of the clamping blocks 305 is two, the bottom of the two clamping blocks 305 is provided with an empty groove 307, the back of the clamping block 305 is fixed with a protrusion 312, and the protrusion 312 passes through the inclined groove 311.

[0031] In addition, the clamp seat 301 is fixedly connected to a support shaft 308 , a first cylinder 309 is installed inside the support shaft 308 , an output end of the first cylinder 309 passes through the interior of the empty slot 307 and is fixed with a transverse plate 310 , and two inclined slots 311 are provided on the back of the clamp seat 301 .

[0032] It should be noted that the material to be subjected to the tensile test is sampled and then clamped by the fixing mechanism 3, and the sampled material is placed inside the two clamping blocks 305. If the tested material is in the form of a strip, it can be directly placed on the plane of the two clamping blocks 305. If the tested material is in the form of a circle, it can be placed inside the arc groove 306. Then, the output end of the first cylinder 309 extends to drive the cross plate 310 to rise inside the empty groove 307. When the cross plate 310 rises, it pushes up the two clamping blocks 305. Since the convex block 312 on the back of the clamping block 305 is located inside the inclined groove 311, when the clamping block 305 rises, the convex block 312 It moves upward inside the inclined groove 311. Since the two inclined grooves 311 are wider at the bottom and narrower at the top, when the protrusion 312 moves, the output end of the telescopic rod 304 extends to drive the clamping block 305 to move horizontally. Then the distance between the two clamping blocks 305 is shortened and the tested material is clamped and fixed. After that, the motor inside the workbench 8 starts to drive the screw rod 6 to rotate. Since the limit rod 2 passes through the lower top plate 7, the lower top plate 7 can be prevented from rotating. Therefore, when the screw rod 6 rotates, it will drive the lower top plate 7 to move downward. The lower top plate 7 descends, driving the bottom clamping seat 301 to descend, and then the tested material is stretched to achieve stretching detection.

[0033] Furthermore, when the material needs to be subjected to a compression test, the material can be placed on top of the pressure head 11, and then the lower top plate 7 is lowered to drive the top pressure head 11 to descend and press the material, which is conducive to achieving the compression test.

[0034] Next, the bending detection mechanism 4 includes a support frame 401 fixedly arranged on the side of the workbench 8, an inclined frame 402 is fixed on the top of the support frame 401, the inclined frame 402 is provided with a circular hole 403 and a discharge port 413, a movable circular shaft 404 is arranged inside the circular hole 403, a baffle 405 is fixed on the top of the circular shaft 404, and an iron ball 406 is arranged inside the inclined frame 402.

[0035] In addition, the support frame 401 is rotatably connected to a support rod 407, an iron block 408 is fixed to one end of the support rod 407, and a buffer box 409 is inserted to the other end of the support rod 407, a detection groove 410 is provided at the bottom of the support frame 401, and a stop bar 411 is provided on the inner wall of the detection groove 410, a second cylinder 412 is installed on one side of the lower top plate 7, an accessory groove 12 is provided on one side of the support frame 401, and a cover plate is provided on the outside of the accessory groove 12, and the accessory groove 12 is used to place spare accessories of the universal testing machine.

[0036] It can be concluded that when the material needs to be bent, the material is placed on the top of the stop bar 411, and then the output end of the second cylinder 412 extends out to the top of the support rod 407. When the lower top plate 7 descends, the second cylinder 412 is driven to descend. Then the output end of the second cylinder 412 presses the support rod 407 to make the support rod 407 rotate clockwise, and then the buffer box 409 rotates to the top of the circular shaft 404, and then the circular shaft 404 rises in the circular hole 403 and drives the baffle 405 to rise to open the discharge port 413, and then the iron ball 406 in the inclined frame 402 is discharged from the discharge port 413 into the interior of the buffer box 409. The weight of the iron block 408 is The weight of the buffer box 409 is three times the weight, and then the output end of the second cylinder 412 is retracted. Since the support rod 407 is located at one end of the iron block 408 and is heavier, the support rod 407 will rotate in the opposite direction and reset at this time. Then the circular shaft 404 descends to make the baffle 405 cover the discharge port 413 again. The above operation can realize the cyclic falling of the iron ball 406, and the operation of the bending detection mechanism 4 is controlled by the extension and contraction of the second cylinder 412. When the bending test is not needed, the output end of the second cylinder 412 is retracted, and the iron ball 406 passes through the buffer box 409 and hits the material in the detection groove 410, and then the bending changes of the material after being compressed are observed to realize the test of its bending performance.

[0037] Working principle: Take a sample of the material to be subjected to the tensile test and clamp it through the fixing mechanism 3, put the sampled material into the two clamping blocks 305, if the tested material is in the shape of a strip, it can be directly placed on the plane of the two clamping blocks 305, if the tested material is in the shape of a circle, it can be placed into the arc groove 306, then the output end of the first cylinder 309 extends to drive the cross plate 310 to rise inside the empty groove 307, when the cross plate 310 rises, it pushes up the two clamping blocks 305 to rise, because the convex block 312 on the back of the clamping block 305 is located inside the inclined groove 311, so when the clamping block 305 rises, the convex block 312 is in The inside of the inclined groove 311 moves upward. Since the two inclined grooves 311 are wider at the bottom and narrower at the top, when the protrusion 312 moves, the output end of the telescopic rod 304 extends to drive the clamping block 305 to move horizontally. Then the distance between the two clamping blocks 305 is shortened and the tested material is clamped and fixed. After that, the motor inside the workbench 8 starts to drive the screw rod 6 to rotate. Since the limit rod 2 passes through the lower top plate 7, the lower top plate 7 can be prevented from rotating. Therefore, when the screw rod 6 rotates, it will drive the lower top plate 7 to move downward. The lower top plate 7 descends, driving the bottom clamping seat 301 to descend, and then the tested material is stretched to achieve stretching detection.

[0038] When the material needs to be subjected to a compression test, the material can be placed on top of the pressure head 11, and then the lower top plate 7 is lowered to drive the top pressure head 11 to descend and press the material, which is conducive to achieving the compression test.

[0039] When the material needs to be bent, the material is placed on the top of the stop bar 411, and then the output end of the second cylinder 412 extends out to the top of the support rod 407. When the lower top plate 7 descends, it drives the second cylinder 412 to descend. Then the output end of the second cylinder 412 presses the support rod 407 to make the support rod 407 rotate clockwise. Then the buffer box 409 rotates to the top of the circular shaft 404. Then the circular shaft 404 rises in the circular hole 403 and drives the baffle 405 to rise to open the discharge port 413. Then the iron ball 406 in the inclined frame 402 is discharged from the discharge port 413 into the interior of the buffer box 409. The weight of the iron block 408 is three times the weight of the buffer box 409. , then the output end of the second cylinder 412 retracts, and since the support rod 407 is located at one end of the iron block 408 and is heavier, the support rod 407 will rotate in the opposite direction and reset at this time, and then the circular shaft 404 descends to make the baffle 405 block the discharge port 413 again. The above operation can realize the cyclic falling of the iron ball 406, and the operation of the bending detection mechanism 4 is controlled by the extension and contraction of the second cylinder 412. When the bending test is not needed, the output end of the second cylinder 412 retracts, and the iron ball 406 passes through the buffer box 409 and hits the material in the detection groove 410, and then the bending change of the material after being compressed is observed to realize the test of its bending performance, so as to detect whether the material meets the specified requirements.

[0040] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto.
