Description

Technical Field

[0001] This invention relates to the technical field of engineering test sampling devices, and in particular to a sampling device for engineering test detection with storage function. Background Technology

[0002] In engineering tests, insulation board sampling is usually done by taking core samples from the wall surface, which can damage the wall. Therefore, in actual operation, a sample of a specified size is cut from the corner of the insulation board for testing.

[0003] Chinese patent document CN213544068U discloses a sampling machine for detecting the structure of a thermal insulation board, which includes an installation cylinder, a connecting plate, a cylinder, and a hollow drill bit. The cylinder is fixedly connected to the installation cylinder, and one end of the cylinder is fixedly connected to the connecting plate. The connecting plate is located inside the installation cylinder and is slidably connected to the inner wall of the installation cylinder. A motor is fixedly connected to the connecting plate, and the motor is fixedly connected to the hollow drill bit. The hollow drill bit is rotatably connected to the connecting plate. An ejector is provided inside the air drill bit, and the ejector is fixedly connected to the end of the hollow drill bit near the connecting plate. This device reduces the difficulty of ejecting the sample core from the hollow drill bit, shortens the sample core removal time, and reduces the degree of damage during sample core removal. However, it still has the following shortcomings:

[0004] The device has difficulty storing multiple core samples at the same time. Even if multiple insulation board core samples are temporarily stored in the hollow drill bit through repeated operation, the core samples will be damaged due to shaking and collision, which will also affect the normal operation of the device. Summary of the Invention

[0013] Preferably, the upper four corners of the movable plate are provided with grooves II, and two grooves II located on the same horizontal line are provided with an adsorption mechanism.

[0014] The adsorption mechanism includes an air guide tube 1 and an air guide tube 2, which are respectively fixedly installed in two grooves 2. The upper ends of the air guide tube 1 and the air guide tube 2 are provided with suction cups for temporary fixation. The lower part of the outer surface of the air guide tube 1 and the air guide tube 2, which are close to each other, is provided with an air guide tube 3 that communicates with the inner cavity of the air guide tube 1 and the air guide tube 2. The lower part of the outer surface of the air guide tube 1, which is away from the air guide tube 3, is provided with an air guide tube 4 that communicates with its inner cavity. The outer surface of the air guide tube 4 and the air guide tube 3, which are close to the slide groove 3, are provided with an air guide tube 5. The outer surfaces of the two air guide tubes 5 are respectively provided with a small one-way valve 1 and a small one-way valve 2 for controlling the air inlet and outlet. The two air guide tubes 5, which are close to the slide groove 3, are provided with an air bladder that extends into the slide groove 3. The air bladder is provided with a sponge pad inside.

[0015] The upper and lower parts of the front and rear outer end walls of the movable plate are provided with T-shaped grooves. The two T-shaped grooves on the same side and the sliding groove three are provided with a squeezing block for squeezing the airbag. The end of the squeezing block near the rotating plate one is provided with a pull rope between it and the limiting mechanism.

[0016] Preferably, the portion of the extrusion block near the rotating plate is a magnetic structure that repels the limiting mechanism, while the portion of the extrusion block away from the rotating plate is a flexible structure that facilitates compression.

[0017] Preferably, the sponge pad has an isosceles trapezoidal structure, and both sides of the extrusion block are inclined structures for the sponge pad.

[0018] Preferably, the front end of the front sealing plate is provided with a servo motor, the output end of the servo motor extends into the interior of the front sealing plate and is provided with a threaded rod rotatably connected to the interior of the front sealing plate via a coupling, and the end of the extrusion plate near the threaded rod is provided with a sliding groove, the interior of the sliding groove is provided with a moving block for sliding up and down, the moving block is located on the outside of the threaded rod and is threadedly connected to the threaded rod.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. This invention, by setting up a threaded rod, a sliding groove, and a moving block, enables the extrusion plate to drive the rotating plate to rotate, and then the moving plate drives the rotating plate to rotate. This controls the moving plate to move downwards while maintaining a horizontal state, sending the insulation board samples into the collection box for classified storage by the partition plate, avoiding damage caused by collisions between the samples. In addition, the baffle plate facilitates the up and down movement of the partition plate from outside the device, allowing the stored samples to be moved apart to avoid affecting the subsequent normal operation of the device.

[0023] 2. By setting up structures such as an adsorption mechanism, a squeezing block, and a limiting mechanism, the sample is temporarily adsorbed and fixed on the moving plate, preventing the sample from shifting on the moving plate and reducing the probability of sample collision damage. Then, the repulsive force between the squeezing block and the limiting mechanism is used to squeeze the airbag in advance before the squeezing plate moves to the moving plate. Through a small one-way valve, air flows into the suction cup, thereby releasing the suction cup from adsorbing and fixing the sample, and preventing the squeezing plate and the sample from squeezing each other, which would cause damage to the sample and the adsorption mechanism.

[0035] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0036] Example 1

[0037] like Figure 1-7 As shown, this embodiment discloses a sampling device for engineering testing with storage function, including an L-shaped base 1. A groove 15 is provided on the upper side of the horizontal part of the L-shaped base 1 near its vertical part. An L-shaped cutting groove 14 is provided at the right rear corner of the upper part of the groove 15, which penetrates the lower end of the L-shaped base 1. This facilitates the cutting of the insulation board into a specified size in one step along the L-shaped cutting groove 14. An L-shaped limiting block 16 is provided on the upper side of the horizontal part of the L-shaped base 1 away from its vertical part, adjacent to the groove 15. The angle between the vertical part and the horizontal part of the L-shaped limiting block 16 is an inclined structure, which facilitates the use of the height difference between the vertical part and the horizontal part of the L-shaped limiting block 16 to move the returning extrusion plate 41 upward. Then, the limiting mechanism 413 is used to pull up the rotating plate 43 again, so that the moving mechanism 4 returns to the initial state.

[0038] For details, please refer to Figure 2-4The L-shaped base 1 has a rear sealing plate 11 and a front sealing plate 12 on its front and rear outer end walls, respectively. The side wall thickness of the front sealing plate 12 is greater than that of the rear sealing plate 11. A servo motor 2 is provided at the front end of the front sealing plate 12. The servo motor 2 can rotate forward and backward, which facilitates pulling the extrusion plate 41 back to its initial position. The output end of the servo motor 2 extends into the interior of the front sealing plate 12 and is connected to a threaded rod 21 rotatably inside the front sealing plate 12 via a coupling. A limiting plate 3 is provided on the upper part of the ends of the rear sealing plate 11 and the front sealing plate 12 that are close to each other. The limiting plate 3 is fixedly connected between the rear sealing plate 11 and the front sealing plate 12 by bolts, and is connected to the L-shaped base. The seats 1 do not contact each other, which facilitates the limiting of the moving mechanism 4. The right end of the limiting plate 3 is provided with a trapezoidal groove 34 that runs through its upper and lower ends. The left inclined inner wall of the trapezoidal groove 34 is used to limit the maximum tilt angle of the rotating plate 43. The lower end of the limiting plate 3 is provided with a right-angled trapezoidal plate 32 and a right-angled trapezoidal plate 33 located at the bottom of the front and rear side walls of the trapezoidal groove 34, respectively. Since the horizontal part of the L-shaped cutting groove 14 is located at the upper rear part of the horizontal part of the L-shaped base 1, the front and rear side walls of the trapezoidal groove 34 are of different thicknesses in order to match the L-shaped cutting groove 14. Therefore, the width of the right-angled trapezoidal plate 32 is greater than the width of the right-angled trapezoidal plate 33.

[0039] Specifically, an L-shaped limiting plate 31 is provided on the upper part of the limiting plate 3 near the L-shaped cutting groove 14. The corner of the insulation board to be cut is pressed against the inner side of the L-shaped limiting plate 31, and then the insulation board is cut along the L-shaped cutting groove 14, which facilitates the cutting of the specified size and avoids the need to remeasure the size before each cut. The length of the horizontal part and the length of the vertical part of the L-shaped limiting plate 31 are equal to the length and width of the moving plate 44, respectively. That is, the end face of the horizontal and vertical parts of the L-shaped limiting plate 31 that is far away from each other is located on the same vertical plane as the two inner side walls of the L-shaped cutting groove 14, thereby avoiding affecting the cutting of the insulation board template. The two horizontal sides at the angle between the horizontal and vertical parts of the L-shaped limiting plate 31 are located on the same vertical plane as two of the top sides of the trapezoidal groove 34, which forces the horizontal cross section of the cut template to be consistent with the horizontal cross section of the moving plate 44, and avoids the template position from shifting when the moving plate 44 moves.

[0040] For details, please refer to Figure 4-6To avoid damage to the cut samples or mixing with other samples, making them indistinguishable, this embodiment provides a sample transfer mechanism 4 between the groove 15 and the trapezoidal groove 34. The transfer mechanism 4 includes a pressing plate 41 slidably connected between the upper end of the L-shaped limiting block 16 and the lower left end of the limiting plate 3, and a positioning plate 42 fixedly connected to the bottom wall of the groove 15. The pressing plate 41 first moves at the upper end of the vertical part of the L-shaped limiting block 16, and then moves on the horizontal part of the L-shaped limiting block 16 and the rotating plate 43. A sliding groove 411 is provided at one end of the pressing plate 41 near the threaded rod 21. The interior of the sliding groove 411 is provided with a groove for... The sliding block 412 moves up and down. When the extrusion plate 41 moves above the vertical part of the L-shaped limiting block 16, the sliding block 412 is located in the lower middle part of the slide groove 411. When the extrusion plate 41 falls to the upper horizontal part of the L-shaped limiting block 16, the sliding block 412 slides to the upper middle part of the slide groove 411 to facilitate the continued movement of the extrusion plate 41 by controlling the sliding block 412. The sliding block 412 is located on the outside of the threaded rod 21 and is threadedly connected to the threaded rod 21. That is, the servo motor 2 controls the rotation of the threaded rod 21 and controls the movement of the sliding block 412 threadedly connected to the threaded rod 21, thereby controlling the moving mechanism 4 to perform deformation work.

[0041] Specifically, a portion of the positioning plate 42 away from the vertical part of the L-shaped base 1 and a portion near the vertical part of the L-shaped base 1 are respectively provided with a rotating plate 43 and a rotating plate 45. The portions of the rotating plates 43 and 45 away from the positioning plate 42 are jointly provided with a movable plate 44 for carrying the sample. That is, the positioning plate 42, rotating plate 43, movable plate 44, and rotating plate 45 together form a rotatable and deformable parallelogram. The front and rear outer end walls of the rotating plate 43 are each provided with a groove 431 penetrating its end away from the positioning plate 42. The bottom of the pressing plate 41 near the rotating plate 43 has two... A limiting mechanism 413 is slidably connected in two slide grooves 431. The limiting mechanism 413 includes a steering plate rotatably connected to the extrusion plate 41 and a slide bar fixedly connected to a part of the steering plate away from the extrusion plate 41. The slide bar is slidably connected in the slide groove 431 to facilitate dragging the rotating plate 43. This is prior art, so it will not be described in detail. The limiting mechanism 413 is magnetic, that is, the slide bar is a magnetic rod, which facilitates the use of the repulsive force between it and the extrusion block 444 to push the extrusion block 444 to move in advance, extruding the airbag 4439 and releasing the suction cup 4431 from the adsorption force of the insulation board sample.

[0042] As described above, the edge of the insulation board to be cut is first placed against the inner side of the L-shaped limiting plate 31, and then the insulation board is cut along the L-shaped cutting groove 14, so that the sample stays on the moving plate 44. Then, the threaded rod 21 is rotated by the servo motor 2, which forces the moving block 412, which is threadedly connected to the threaded rod 21, to drive the pressing plate 41 to move and press the rotating plate 43, forcing the rotating plate 43 to rotate. The rotation of the rotating plate 43 will press the moving plate 44 to move, forcing the rotating plate 45 to rotate, so that the moving plate 44 is kept in a horizontal state and tilted downwards, so that the sample on the moving plate 44 is transported into the device.

[0043] Furthermore, the distance between the inclined structure at the angle between the vertical and horizontal parts of the L-shaped limiting block 16 and the inclined surfaces of the right-angled trapezoidal plate 32 and the right-angled trapezoidal plate 33 is equal to the length of the extrusion plate 41. This causes the extrusion plate 41 to move a certain distance horizontally and then move a small distance downward under the action of the inclined structure of the L-shaped limiting block 16 and the inclined surfaces of the right-angled trapezoidal plate 32 and the right-angled trapezoidal plate 33, flattening the rotating plate 43 and making the upper surfaces of the rotating plate 43 and the moving plate 44 on the same horizontal line. This allows the extrusion plate 41 to continue sliding on the horizontal part of the L-shaped limiting block 16 and the rotating plate 43.

[0044] Furthermore, the front and rear outer end walls of the movable plate 44 are provided with sliding grooves 3 441. When the rotating plate 1 43 is in a horizontal state, the sliding groove 3 441 and the sliding groove 2 431 are on the same horizontal line, so that the limiting mechanism 413 can slide directly into the sliding groove 3 441, thereby allowing the extrusion plate 41 to move horizontally onto the movable plate 44 and push the sample into the collection box 5.

[0045] For further details, please refer to Figure 1 , Figure 3 and Figure 7The right end of the vertical section of the L-shaped base 1 has an installation groove 13. Inside the installation groove 13 is a collection box 5 for temporary sample storage. The middle of the right end of the collection box 5 has a vertical groove 51 that penetrates its inner cavity. The upper and lower middle parts of the front inner wall of the vertical groove 51 are evenly provided with multiple horizontal grooves 2 53 and multiple horizontal grooves 1 52, and the shape and size of the horizontal grooves 2 53 and horizontal grooves 1 52 are equal. A large distance is left between the lowermost horizontal groove 2 53 and the uppermost horizontal groove 1 52, which is convenient for the sample to be placed inside. One partition plate 55 is moved to a designated position. The second purpose is to leave enough space for the sample to be moved to the partition plate 55 at the designated position. Multiple partition plates 55 are provided in the upper part of the inner cavity of the collection box 5. A baffle 54 for sliding back and forth is provided at the right end of the partition plate 55. A part of the baffle 54 away from the partition plate 55 passes through the horizontal groove 2 53 and extends to the outside of the collection box 5. The height of the partition plate 55 is limited by moving the baffle 54 forward into the horizontal groove 1 52 or the horizontal groove 2 53, so as to facilitate the control of the partition plate 55 to move up and down from outside the device.

[0046] When the moving plate 44 and the rotating plate 43 are on the same horizontal line, and the baffle 54 on one of the partition plates 55 is located in the uppermost horizontal groove 52, the upper end face of the moving plate 44 is on the same horizontal line as the higher side of the partition plate 55, so that the squeezing plate 41 can push the sample onto the partition plate 55 for storage.

[0047] Furthermore, the upper surface of the partition plate 55 is an inclined structure with the left side higher than the right side, so that the sample that has moved most of its body onto the partition plate 55 can continue to slide down along the inclined surface and into the collection box 5, thus avoiding the subsequent moving plate 44 from knocking over and damaging the previous sample when the moving mechanism 4 is working repeatedly.

[0048] Therefore, the specific implementation method of this embodiment is as follows:

[0049] First, the edge of the insulation board to be cut is placed against the inside of the L-shaped limiting plate 31. Then, the insulation board is cut along the L-shaped cutting groove 14, so that the sample is placed on the moving plate 44. Then, the threaded rod 21 is rotated by the servo motor 2, which forces the moving block 412, which is threaded to the threaded rod 21, to move the pressing plate 41 to press the rotating plate 43. This forces the rotating plate 43 to rotate, and the rotation of the rotating plate 43 will in turn press the moving plate 44 to move, forcing the rotating plate 45 to rotate. This keeps the moving plate 44 in a horizontal state and tilts downward. The sample on the moving plate 44 is transported into the device. Then, the pressing plate 41 moves down under the limiting action of the inclined structure on the upper part of the L-shaped limiting block 16 and the inclined surfaces of the right trapezoidal plate 1 32 and the right trapezoidal plate 2 33, so that the moving plate 44 and the rotating plate 1 43 can rotate to the same horizontal plane, so that the slide 2 431 and the slide 3 441 are connected, and the limiting mechanism 413 slides from the slide 2 431 to the slide 3 441. Then the pressing plate 41 moves from the rotating plate 1 43 to the moving plate 44, pushing the sample into the partition plate 55 in the collection box 5.

[0050] Then, the threaded rod 21 is rotated in the opposite direction, dragging the extrusion plate 41 back to move, so that the limiting mechanism 413 returns from the slide groove 3 441 to the slide groove 2 431. Then, the inclined structure of the upper part of the L-shaped limiting block 16 is used to make the extrusion plate 41 move upward. Then, the extrusion plate 41 pulls the rotating plate 1 43 to rotate and tilt through the limiting mechanism 413, so that the moving plate 44 moves upward and raises the remaining sample plate on the moving plate 44, so that the sample plate tilts at a larger angle, so that the sample plate can slide on the partition plate 55 and go deeper into the collection box 5. When the rotating plate 1 43 is pressed tightly against the inclined surface of the trapezoidal groove 34 again, the upper end surface of the moving plate 44 is in the same horizontal plane as the upper end surface of the limiting plate 3 and the horizontal part of the L-shaped base 1.

[0051] When the moving mechanism 4 returns to its initial state, the baffle 54 is moved backward so that it enters the vertical groove 51. Then, the baffle 54 is moved downward to control the partition plate 55 to move downward, thereby removing the partition plate 55 containing the template. The above steps are repeated to move a blank partition plate 55 to the designated position to receive the templates cut out later.

[0052] Example 2

[0053] This embodiment adds an adsorption mechanism 443 to the first embodiment to facilitate the adsorption and fixation of the insulation board, preventing the insulation board sample from shifting during movement. Figure 6 and Figure 8-10As shown, the upper four corners of the moving plate 44 are provided with grooves 46. The two grooves 46 located on the same horizontal line are provided with an adsorption mechanism 443. The adsorption mechanism 443 has two functions: first, to temporarily fix the insulation plate placed on the device to prevent the insulation plate from changing position during cutting, which would result in failure to cut to the specified size. The insulation plate can also be easily removed afterwards. Second, to prevent the cut sample from shaking and shifting when it moves with the moving plate 44, which would prevent the sample from entering the collection box 5 smoothly.

[0054] For details, please refer to Figure 8 The adsorption mechanism 443 includes a first air pipe 4432 and a second air pipe 4433, which are respectively fixedly installed in two second grooves 46. The upper ends of both the first air pipe 4432 and the second air pipe 4433 are provided with suction cups 4431 for temporary fixation. The horizontal height of the suction cups 4431 is slightly higher than the upper surface of the moving plate 44. When the suction cups 4431 are squeezed, they will completely retract into the second groove 46. The lower part of the outer surface of the first air pipe 4432 and the second air pipe 4433, which are close to each other, is provided with a third air pipe 4434 that communicates with the inner cavities of the first air pipe 4432 and the second air pipe 4433. The first air pipe 4432 is located away from the second air pipe. A portion of the outer surface of the third 4434 is provided with an air guide tube 4435 communicating with its inner cavity. Both the fourth 4435 and the third 4434 are provided with air guide tubes 4437 on a portion of their outer surfaces near the slide groove 441. The outer surfaces of the two air guide tubes 4437 are respectively provided with a small one-way valve 4436 and a small one-way valve 4438 for controlling the entry and exit of air. The small one-way valve 4436 allows gas to flow from the airbag 4439 into the air guide tubes 4432 and 4433, while the small one-way valve 4438 allows gas to flow from the air guide tubes 4432 and 4433 into the airbag 4439.

[0055] Two air ducts 4437 are provided with a portion of the slide 441 near the slide 441, and together they are provided with an airbag 4439 extending into the slide 441. The deformable nature of the airbag 4439 is used to temporarily store the air in the air duct 1 4432 and the air duct 2 4433. The airbag 4439 is provided with a sponge pad inside, which makes it easy to push the airbag 4439 to quickly return to its original shape, while defining the approximate shape of the airbag 4439, so that the airbag 4439 can be squeezed and contracted by the compression block 444.

[0056] Furthermore, T-slots 442 are provided on the upper and lower parts of the front and rear outer end walls of the movable plate 44. The two T-slots 442 on the same side and the sliding groove 441 are provided with a compression block 444 for compressing the airbag 4439. The length of the compression block 444 is greater than the distance between the movable plate 44 and the partition plate 55 when they are on the same horizontal plane. A pull rope 47 is provided between the end of the compression block 444 near the rotating plate 43 and the limiting mechanism 413, so that the compression block 444 can be dragged back to the initial position near the rotating plate 43 by pulling the rope 47.

[0057] Furthermore, the part of the extrusion block 444 near the rotating plate 43 is a magnetic structure that repels the limiting mechanism 413, while the part of the extrusion block 444 away from the rotating plate 43 is a flexible structure that is easy to compress. By utilizing the mutual repulsion between the extrusion block 444 and the limiting mechanism 413, the extrusion block 444 moves toward the collection box 5 before the limiting mechanism 413 enters the slide groove 441, extruding the airbag 4439. This causes the air in the airbag 4439 to enter the air guide pipe 4432 and the air guide pipe 4433 through one of the air guide pipes 4437 and the small one-way valve 4436, and finally flows into the suction cup 4431, thereby relieving the negative pressure adsorption of the suction cup 4431 on the insulation board sample, making it easier for the extrusion plate 41 to push the sample to move.

[0058] The flexible structure on the extrusion block 444 facilitates the extrusion block 444 to impact the partition plate 55 for compression, thereby increasing the moving distance of the extrusion plate 41 and making it easier to push most of the sample onto the partition plate 55, thus preventing the partition plate 55 from falling off after the moving plate 44 leaves.

[0059] Furthermore, the sponge pad has an isosceles trapezoidal structure, and the left and right sides of the compression block 444 are inclined structures for the sponge pad, which defines the approximate shape of the airbag 4439, making it easier for the airbag 4439 to be compressed and contracted by the compression block 444.

[0060] Therefore, the specific implementation method of this embodiment is as follows:

[0061] When the insulation board is placed on the device, press the insulation board to squeeze the suction cup 4431. The air in the suction cup 4431 is squeezed into the airbag 4439 through the small one-way valve 4438, causing the airbag 4439 to expand. This allows the suction cup 4431 to adhere and fix the insulation board. After the sample is cut off, the remaining insulation board can be removed immediately, while the sample remains fixed on the moving plate 44. Then, when the squeezing plate 41 moves the limiting mechanism 413, the repulsive force between the limiting mechanism 413 and the squeezing block 444 is used to push the squeezing block 444 towards the collection box 5 in advance, squeezing the airbag 4439. This allows the air in the airbag 4439 to enter the suction cup 4431 through the small one-way valve 4436, releasing the adhesion to the sample. Afterward, the sample will be pushed into the collection box 5 for temporary classification and storage as the squeezing plate 41 moves.
