Description

Technical Field

[0001] The invention relates to the technical field of engineering material detection, in particular to a drilling sampling device for engineering material detection. Background Art

[0002] During the construction process, for the sake of safety, the completed construction materials will be tested, and for the authenticity of the test, it is usually necessary to test the inside of the construction materials, because it is necessary to drill holes in the construction materials and take out the internal materials of the construction materials for testing. Sampling of construction wall materials is an important step to ensure the quality and performance of the materials. During the sampling process, it is necessary to drill holes with a drilling rig. According to the actual construction situation, when selecting the sampling location, it is necessary to consider whether the location can represent the entire building facade, and then perform the drilling operation. After drilling to the predetermined depth, the construction material sample is obtained in the sampling tube.

[0003] At present, in the existing technology, the sampling tool is directly placed on the crossbar of the scaffolding for support. Since the sampling tool continuously drills into the wall during drilling, the sampled material is easily broken due to the drilling vibration. In addition, due to the large range of the wall, sampling is required at multiple points, and traditional sampling equipment requires multiple samplings, which is inefficient.

[0006] Preferably, the sampling assembly includes a positioning seat, and the positioning seats are provided in four numbers. The four positioning seats are movably installed inside the turntable, and the outer surface of the positioning seat is fixedly installed with a connecting shaft, and the outer surface of the connecting shaft is movably installed with a limiting pad, and the outer surface of the limiting pad is fixedly installed with an outer cover. The positioning seat rotates with the turntable so that the crushing cutter contacts the wall surface. At this time, the wall surface is drilled into the wall surface by the crushing cutter, so that the wall surface sample enters the cavity of the conical cover along the crushing cutter. At this time, the extrusion and contraction part in the conical cover is squeezed by the sample and slides toward the side of the positioning round block, thereby changing the cavity capacity in the conical cover. Since the conical cover is provided in multiple groups, the wall can be sampled at multiple points at the same time, and then the staff removes the positioning seat from the driving rotating part to facilitate the removal of the sampled wall in the conical cover.

[0007] Preferably, a positioning block is fixedly installed inside the cavity of the outer cover, an extrusion contraction piece is fixedly installed on the surface of the positioning block, an extrusion cone is fixedly installed on the outer surface of the positioning block, and a crushing cutter is fixedly installed on the outer surface of the outer cover.

The cavity sample is collected in the conical cover, and as the crushing cutter continues to drill, the sample in the conical cover squeezes the extrusion shrinkage member, and the extrusion shrinkage member is forced to shrink toward one side of the outer cover to adjust the sample collection capacity according to the drilling depth.

[0010] Preferably, the outer surface of the shrink cover is sleeved with a compression pad, and a V-shaped cover is fixedly installed on the outer surface of the compression pad, and the V-shaped cover is sleeved on the outer side of the shrink cover. A circular hole is opened in the middle of the inner part of the compression pad, and the circular hole is adapted to the sleeve shaft. The compression pad is squeezed by the sample and slides on the surface of the shaft through the circular hole. At this time, the segmented pad and the V-shaped cover are squeezed and extend outward in the conical cover. Since the compression pad is set to a flexible material, the sample is protected when the outer ring is drilled for sampling to prevent the sample from breaking when drilling.

[0011] Preferably, the position limiting protection member includes a bottom support frame, the bottom support frame is fixedly mounted on the top side of the base, a support bent rod is fixedly mounted on one side of the outer surface of the bottom support frame, a support ring is fixedly mounted on the outer surface of the support bent rod, a first magnetic block is fixedly mounted on the surface of the support ring, and there are three first magnetic blocks, which are distributed in a circular shape on the surface of the support ring. The staff moves the guide rail to make the rotating shaft slide on the inner wall of the middle ring. At this time, the turntable is lower than the wall surface, so that the curved spring piece is pushed by the turntable to slide to one side of the guide groove, so that the curved spring piece pushes the magnetic support frame, so that the magnetic support frame drives the middle ring to be pushed to slide on the surface of the frame ring, so that the magnetic support frame moves to the side of the first magnetic block. Due to the magnetic repulsion between the first magnetic block and the magnetic support frame, the magnetic support frame is deformed.

[0012] Preferably, a frame ring is fixedly installed inside the bottom support frame, and a magnetic frame is sleeved on the outer surface of the frame ring.

[0015] The present invention provides a drilling sampling device for engineering material detection. It has the following beneficial effects: 1. The drilling sampling equipment for testing engineering materials, when testing the wall materials of the construction project, the staff moves the guide rail on the base so that the guide rail drives the frame plate to slide and move, so as to adjust the displacement of the driving rotor, and then the staff starts the motor so that the output end of the motor drives the driving rotor to rotate, so that the driving rotor and the sampling component rotate on the wall surface, and the sampling component samples the wall material.

[0016] 2. The drilling sampling equipment for engineering material testing rotates with the turntable through the positioning seat to make the crushing cutter contact the wall. At this time, the wall is drilled into the wall by the crushing cutter, so that the wall sample enters the cavity of the conical cover along the crushing cutter. At this time, the extrusion and contraction parts in the conical cover are squeezed by the sample and slide toward the side of the positioning round block, thereby changing the cavity capacity in the conical cover. Since the conical cover is set in multiple groups, the wall can be sampled at multiple points at the same time, and then the staff will remove the positioning seat from the driving rotary part to facilitate the removal of the sampled wall in the conical cover.

[0017] 3. The drilling and sampling equipment for engineering material testing drives multiple sets of positioning seats to rotate through a turntable, so that the conical cover drives the crushing cutters to drill into the wall. At this time, the multiple sets of crushing cutters rotate at high speed and drill into the wall. The outer ring sleeved on the end of the conical cover drives the curved piece to rotate through the connecting block, so that the curved piece drives the side blade to drill into the wall. At this time, the holes opened in the outer ring collect the sampled raw materials into the cavity of the conical cover.

[0018] 4. The drilling sampling equipment for engineering material testing collects samples through the cavity into the conical cover. As the crushing cutter continues to drill, the samples in the conical cover squeeze the extrusion and contraction parts. At this time, the extrusion and contraction parts are forced to shrink toward the side of the outer cover to adjust the sample collection capacity according to the drilling depth. The extrusion pad is squeezed by the sample and slides on the surface of the shaft through the circular hole. At this time, the segmented pad and the V-shaped cover are squeezed in the conical cover and extend outward. Since the extrusion pad is set to a flexible material, the sample is protected when the outer ring is drilled and sampled to avoid breakage during drilling.

[0019] 5. The drilling sampling equipment for engineering material testing is moved by the staff to make the rotating shaft slide on the inner wall of the center ring. At this time, the turntable is against the wall, so that the curved spring piece is pushed by the turntable to slide to the side of the guide groove, so that the curved spring piece pushes the magnetic support frame, so that the magnetic support frame drives the center ring to be pushed to slide on the surface of the frame ring, and the magnetic support frame is displaced to the side of the first magnetic block. Due to the magnetic repulsion between the first magnetic block and the magnetic support frame, the magnetic support frame is deformed, the first magnetic block and the second magnetic block are magnetically repelled, and the second magnetic block slides and displaces inside the cushion block. At this time, the positioning block is displaced toward the surface of the curved spring piece with the displacement of the second magnetic block, so that the spring is pulled and deformed, and the curved spring piece is stably supported by the cushion block.

The limiting protective member 4 is sleeved on the outer surface of the driving rotating member 3, and the limiting protective member 4 is fixedly mounted on the top side of the base 1; when inspecting the wall materials of the construction project, the staff moves the guide rail 7 on the base 1 so that the guide rail 7 drives the frame plate 6 to slide and displace to adjust the displacement of the driving rotating member 3, and then the staff starts the motor 5 so that the output end of the motor 5 drives the driving rotating member 3 to rotate, so that the driving rotating member 3 and the sampling components 8 rotate on the wall surface, and the sampling components 8 samples the wall materials at this time.

[0024] The driving rotating member 3 includes a rotating shaft 31, which is fixedly mounted at the output end of the motor 5, and the rotating shaft 31 penetrates the limiting protective member 4 and extends to the outside thereof. A guide groove 35 is provided at the end of the outer surface of the rotating shaft 31, and three guide grooves 35 are provided. The three guide grooves 35 are distributed in a circumferential shape on the surface of the rotating shaft 31. A curved spring piece 34 is slidably mounted inside the guide groove 35, and a fixed block 36 is fixedly mounted on the outer surface of the curved spring piece 34. A rotating disk 33 is fixedly mounted on the outer surface of the fixed block 36. The rotating disk 33 is sleeved on the outer surface of the sampling assembly 8, and a crushing side knife 37 is fixedly mounted on the outer surface of the rotating disk 33. The center axis 32 is fixedly mounted at the axis of the rotating disk 33. The staff starts the motor 5, so that the output end of the motor 5 drives the rotating shaft 31 to rotate. At this time, the curved spring piece 34 in the guide groove 35 drives the rotating disk 33 to rotate through the fixed block 36, so that the sampling assembly 8 samples the wall as the rotating disk 33 rotates.

[0025] The second embodiment is based on the first embodiment. Figures 3 to 7 As shown, the position limiting protection member 4 includes a bottom support frame 41, which is fixedly mounted on the top side of the base 1, and a support bent rod 44 is fixedly mounted on one side of the outer surface of the bottom support frame 41, and a support ring 45 is fixedly mounted on the outer surface of the support bent rod 44, and a first magnetic block 47 is fixedly mounted on the surface of the support ring 45, and there are three first magnetic blocks 47, which are distributed in a circumferential shape on the surface of the support ring 45. The staff moves the guide rail 7 to make the rotating shaft 31 slide on the inner wall of the middle ring 46, and at this time, the turntable 33 is lower than the wall surface, so that the curved spring piece 34 is pushed by the turntable 33 to slide to the side of the guide groove 35, so that the curved spring piece 34 pushes the magnetic support frame 43, so that the magnetic support frame 43 drives the middle ring 46 to be pushed to slide on the surface of the frame ring 42, so that the magnetic support frame 43 moves to the side of the first magnetic block 47, and the magnetic support frame 43 is deformed due to the magnetic repulsion between the first magnetic block 47 and the magnetic support frame 43.

[0026] A frame ring 42 is fixedly installed inside the bottom support frame 41, and a magnetic frame 43 is sleeved on the outer surface of the frame ring 42. There are three magnetic frames 43, and a center ring 46 is fixedly installed between the opposite surfaces of the three magnetic frames 43. The center ring 46 is sleeved on the outer surface of the rotating shaft 31, and the center ring 46 is rotatably installed on the surface of the rotating shaft 31.

[0027] The magnetic support frame 43 includes a circular ring 431, which is sleeved on the outer surface of the frame ring 42. A cushion block 433 is fixedly installed on the outer surface of the circular ring 431. A square groove 435 is opened on the surface of the cushion block 433. A spring 434 is fixedly installed inside the square groove 435. A positioning block 438 is fixedly installed on the outer surface of the spring 434. A pad 437 is fixedly installed on the surface of the positioning block 438. The first magnetic block 47 and the second magnetic block 432 are magnetically repelled. The second magnetic block 432 slides inside the cushion block 433. At this time, the positioning block 438 moves toward the surface of the curved spring piece 34 along with the displacement of the second magnetic block 432, so that the spring 434 is pulled to produce deformation, and the curved spring piece 34 is stably supported by the cushion block 433.

[0028] A retractable rod 436 is fixedly mounted on the outer surface of the pad 437 , and the retractable rod 436 passes through the outer side of the cushion block 433 . The surface of the cushion block 433 away from the positioning block 438 is fixedly mounted with the surface of the second magnetic block 432 , and the second magnetic block 432 is adapted to the first magnetic block 47 .

[0029] The third embodiment is based on the first and second embodiments. Figures 10 to 13 As shown, the sampling assembly 8 includes a positioning seat 84, and the positioning seat 84 is provided with four, and the four positioning seats 84 are movably installed inside the rotating disk 33. The outer surface of the positioning seat 84 is fixedly installed with a connecting shaft 83, and the outer surface of the connecting shaft 83 is movably installed with a limiting pad 86, and the outer surface of the limiting pad 86 is fixedly installed with an outer cover 85. The positioning seat 84 rotates with the rotating disk 33, so that the crushing rotary cutter 82 contacts the wall surface. At this time, the wall surface is drilled into the wall surface by the crushing rotary cutter 82, so that the wall surface sample enters the cavity of the conical cover 81 along the crushing rotary cutter 82. At this time, the extrusion and contraction member 87 in the conical cover 81 is squeezed by the sample and slides toward the side of the positioning round block 88, thereby changing the cavity capacity in the conical cover 81. Since the conical cover 81 is set in multiple groups, the wall can be sampled at multiple points at the same time, and then the staff removes the positioning seat 84 from the driving rotating member 3 to facilitate the removal of the sampled wall in the conical cover 81.

[0030] A positioning block 88 is fixedly installed inside the cavity of the outer cover 85, an extrusion contraction piece 87 is fixedly installed on the surface of the positioning block 88, and an extrusion cone 81 is fixedly installed on the outer surface of the positioning block 88. The outer surface of the outer cover 85 is sleeved with a cone hood, and a crushing rotary cutter 82 is fixedly installed on the outer surface end of the cone hood 81.

[0031] The crushing cutter 82 includes an outer ring 822, which is sleeved on the outer surface of the conical cover 81. Connecting blocks 823 are fixedly installed on both sides of the outer surface of the outer ring 822. The connecting blocks 823 are symmetrically arranged with the outer ring 822 as the center. The outer surfaces of the connecting blocks 823 are all fixedly installed with curved pieces 824, and the outer surfaces of the curved pieces 824 are fixedly installed with side blades 821. The turntable 33 drives the multiple groups of positioning seats 84 to rotate, so that the conical cover 81 drives the crushing cutter 82 to drill into the wall. At this time, the multiple groups of crushing cutters 82 rotate at high speed and drill into the wall. The outer ring 822 sleeved on the end of the conical cover 81 drives the curved pieces 824 to rotate through the connecting blocks 823, so that the curved pieces 824 drive the side blades 821 to drill into the wall. At this time, the holes opened in the outer ring 822 collect the sampled raw materials into the cavity of the conical cover 81.

[0032] The extrusion and contraction member 87 comprises a round rod 878, a shaft 879 is fixedly mounted on the outer surface of the round rod 878, a sleeve shaft 875 is fixedly mounted on the outer end of the shaft 879, a round tube 877 is sleeved on the outer surface of the round rod 878, a contraction cover 873 is fixedly mounted on the outer surface of the round tube 877, the contraction cover 873 is sleeved on the outer surface of the shaft 879, and a segmented pad 876 is arranged on the surface of the contraction cover 873. The cavity sample is collected in the conical cover 81, and as the crushing rotary cutter 82 continues to drill, the sample in the conical cover 81 squeezes the extrusion and contraction member 87, and the extrusion and contraction member 87 is forced to contract toward the side of the outer cover 85 to adjust the sample collection capacity according to the drilling depth.

[0033] The outer surface of the shrink cover 873 is sleeved with a squeeze pad 872, and a V-shaped cover 874 is fixedly installed on the outer surface of the squeeze pad 872. The V-shaped cover 874 is sleeved on the outer side of the shrink cover 873. A circular hole 871 is opened in the middle of the squeeze pad 872, and the circular hole 871 is matched with the sleeve shaft 875. The squeeze pad 872 is squeezed by the sample and slides on the surface of the shaft 879 through the circular hole 871. At this time, the segmented pad 876 and the V-shaped cover 874 are squeezed and extend outward in the conical cover 81. Since the squeeze pad 872 is set to a flexible material, it protects the sample when the outer ring 822 is drilled and sampled to prevent the sample from breaking when drilling.

[0034] When in use, the staff starts the motor 5 so that the output end of the motor 5 drives the rotating shaft 31 to rotate. At this time, the curved spring piece 34 in the guide groove 35 drives the turntable 33 to rotate through the fixed block 36, so that the sampling component 8 samples the wall as the turntable 33 rotates.

[0035] The positioning seat 84 rotates with the turntable 33 to make the crushing cutter 82 contact the wall. At this time, the wall is drilled into the wall by the crushing cutter 82, so that the wall sample enters the cavity of the conical cover 81 along the crushing cutter 82. At this time, the extrusion and contraction part 87 in the conical cover 81 is squeezed by the sample and slides toward the side of the positioning round block 88, thereby changing the cavity capacity in the conical cover 81. Since the conical cover 81 is set in multiple groups, the wall can be sampled at multiple points at the same time. Then the staff removes the positioning seat 84 from the driving turntable 3 to facilitate the removal of the sampled wall in the conical cover 81.

[0036] The turntable 33 drives multiple groups of positioning seats 84 to rotate, so that the conical cover 81 drives the crushing cutter 82 to drill into the wall. At this time, the multiple groups of crushing cutters 82 rotate at high speed and drill into the wall. The outer ring 822 sleeved on the end of the conical cover 81 drives the curved piece 824 to rotate through the connecting block 823, so that the curved piece 824 drives the side blade 821 to drill into the wall. At this time, the holes opened in the outer ring 822 collect the sampled raw materials into the cavity of the conical cover 81.

[0037] The cavity samples are collected in the conical cover 81. As the crushing cutter 82 continues to drill, the samples in the conical cover 81 squeeze the extrusion and contraction piece 87. At this time, the extrusion and contraction piece 87 is forced to contract toward the side of the outer cover 85 to adjust the sample collection capacity according to the drilling depth.

[0038] The extrusion pad 872 is squeezed by the sample and slides on the surface of the shaft rod 879 through the circular hole 871. At this time, the segmented pad 876 and the V-shaped cover 874 are squeezed and extend outward inside the conical cover 81. Since the extrusion pad 872 is set to a flexible material, the sample is protected when the outer ring 822 is drilling and sampling to prevent the sample from breaking during drilling.

[0039] The staff moves the guide rail 7 to make the rotating shaft 31 slide on the inner wall of the center ring 46. At this time, the turntable 33 is lower than the wall, so that the curved spring piece 34 is pushed by the turntable 33 to slide to the side of the guide groove 35, so that the curved spring piece 34 pushes the magnetic support frame 43, so that the magnetic support frame 43 drives the center ring 46 to slide on the surface of the frame ring 42, so that the magnetic support frame 43 moves to the side of the first magnetic block 47. Due to the magnetic repulsion between the first magnetic block 47 and the magnetic support frame 43, the magnetic support frame 43 is deformed.

[0040] The first magnetic block 47 and the second magnetic block 432 magnetically repel each other, and the second magnetic block 432 slides inside the cushion block 433.
