Description

Technical Field

[0001] The invention relates to the technical field of external wall thermal insulation material sampling, in particular to a material sampling device for detecting building external wall thermal insulation materials. Background Art

[0002] Wall insulation materials can save a lot of wall materials, improve wall insulation performance, save resources, and reduce environmental pollution. They are new materials that focus on internal and external wall insulation. There are many types of wall energy-saving insulation boards, which can be divided into organic insulation boards, inorganic insulation boards, and composite insulation boards according to their chemical composition. During construction, after the wall foundation construction is completed, the insulation board is attached to the wall, and then the decorative surface is constructed on the outside to form the common building insulation wall now;

[0003] According to the requirements of DGJ08-113-2009 "Construction Quality Acceptance Regulations for Energy-saving Building Projects", on-site physical inspection of the building's exterior wall insulation structure is carried out in the building energy-saving branch project to ensure that the type of insulation material, thickness of the insulation layer and construction method meet the design requirements. At present, we use handheld drilling machines to carry out physical inspections at the construction site. For example, Chinese patent CN218847679U discloses a material sampling device for testing building exterior wall insulation materials. The material sampling device realizes the disassembly of the drill bit body, which solves the problem that the drill bit is fixed by welding and is not convenient for disassembly and replacement, which will reduce the efficiency and quality of drill bit sampling and shorten the service life of the drill bit.

[0004] However, after multiple samplings, a large amount of sample residue will still remain in the drill bit of the drilling machine, which is not easy to clean. If it is repeatedly replaced with a new one, it will be more cumbersome. When it is used for testing again, the residue may contaminate the sample, thus affecting the test results.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. The present invention completes sampling by turning a handle to allow the drill tube to extend into the wall, so that the sampling depth can be manually changed, which makes it more convenient to extract samples at different depths. In addition, by arranging a collecting groove and two curved rods, a triangle can be formed between the collecting groove and the two curved rods when the drill tube is extended, so that the movement of the drill tube is more stable, thereby reducing damage to the wall during sampling. The collecting groove can also collect dust generated during sampling, reducing pollution to the surrounding environment.

[0032] Second, the present invention changes the rotation speed of the drill tube by turning the second handle, so that when facing walls of different hardness, the speed of the drill tube can be reasonably changed. When the wall is softer, the speed of the drill tube is increased, and when the wall is hard, the speed of the drill tube is reduced, thereby reducing the degree of damage to the wall by the drill tube when sampling different wall surfaces, reducing the loss of the drill tube, and further improving the practicability of the sampling device.

[0033] 3. The present invention uses a piston plate to push out the sample inside the drill barrel, which makes it more convenient for users to collect samples. In addition, since the drill barrel moves during sampling, while the piston plate does not move during sampling, the drill barrel and the piston plate will be disconnected during sampling, thereby making the rear end of the drill barrel hollow, preventing the sample from extending into the drill barrel during sampling, thereby increasing the pressure inside the drill barrel and making it difficult to continue extending the drill barrel, thereby further improving the practicality of the sampling device.

[0034] Fourth, the present invention uses a hammer to strike the surface of the drill barrel, thereby causing the surface of the drill barrel to vibrate, further allowing the sample to be better separated from the inside of the drill barrel, and further preventing the sample in the drill barrel from adhering to the inner wall of the drill barrel, further facilitating sampling by the operator.

[0035] Fifth, the present invention reduces sample residues in the drill tube by blowing air into the drill tube, thereby preventing sample contamination caused by a large amount of sample residues in the drill tube after multiple samplings;

[0036] Secondly, the drill tube continues to vibrate during the blowing process, so that the sample is not easily attached to the inner wall of the drill tube, thereby further improving the cleaning effect;

[0037] Thirdly, the setting of the spring not only allows the piston to return to its original position, but also makes it more difficult for the piston tube to move when the toggle rod is not pushed, thereby further improving the stability of the sampling device during use.

[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] For example, see Figures 1 to 9 The present embodiment provides a material sampling device for testing building exterior wall insulation materials, including a bottom plate 1, a universal wheel 11 is rotatably connected to the lower surface of the bottom plate 1, a cross bar 10 is fixedly connected to the upper surface of the bottom plate 1, a collecting box 9 is arranged on the upper surface of the bottom plate 1, a lifting mechanism 2 is also fixedly connected to the upper surface of the bottom plate 1, a sampling box 6 is fixedly connected to the upper surface of the lifting mechanism 2, a drill tube 5 is arranged inside the sampling box 6, the sampling device also includes a rotating insertion component, the rotating insertion component is arranged on the sampling box 6, and the rotating insertion component includes:

[0050] The handle 3 and the fixed groove 28, the side of the sampling box 6 facing the wall is fixedly connected to the side of the fixed groove 28, the side of the fixed groove 28 facing the wall is also fixedly connected to the collecting groove 4, the side of the fixed groove 28 is also fixedly connected to the notch, the groove wall of the fixed groove 28 is rotatably connected to the bidirectional threaded rod 29, the thread surface of the bidirectional threaded rod 29 is threadedly connected to the thread block 30, and the end of the bidirectional threaded rod 29 is fixedly connected to a column, the surface of the column passes through the groove wall of the fixed groove 28, and the end face of the column is fixedly connected to the end face of the handle 3;

[0051] A curved rod 27, one end of which is hinged to the side surface of the threaded block 30, and the other end of which is hinged to a moving ring 25, the inner wall of which is rotatably connected to the surface of the drill tube 5.

[0052] In this embodiment, when using the sampling device, firstly, the height of the drill tube 5 is adjusted by the lifting mechanism 2, and then the sampling device is moved so that the collecting tank 4 is close to the wall. After the collecting tank 4 is close to the wall, the drill tube 5 is rotated. After the drill tube 5 is rotated, the handle 3 is manually turned. The rotation of the handle 3 causes the bidirectional threaded rod 29 to rotate. The rotation of the bidirectional threaded rod 29 causes the two threaded blocks 30 to move away from each other. The further movement of the threaded blocks 30 away from each other causes the two curved rods 27 to deflect, thereby causing the drill tube 5 to move toward the wall surface, so that the drill tube 5 extends into the wall surface for sampling.

[0053] The setting of the rotating insertion component allows the drill tube 5 to be inserted into the wall by rotating the handle 3, thereby completing the sampling, so that the sampling depth can be manually changed, which makes it more convenient to extract samples at different depths. In addition, through the setting of the collecting groove 4 and the two curved rods 27, when the drill tube 5 is inserted, a triangle can be formed between the collecting groove 4 and the two curved rods 27, so that the movement of the drill tube 5 is more stable, thereby reducing the damage to the wall during sampling. The collecting groove 4 can also collect dust generated during sampling, reducing pollution to the surrounding environment.

[0054] It is worth noting that the material sampling device also includes a speed regulating component, which is arranged in the sampling box 6 and includes:

[0055] A handle 2 33 and a threaded rod 37, the end of the threaded rod 37 is rotatably connected to a fixed plate 1 34, the bottom surface of the fixed plate 1 34 is fixedly connected to the inner lower surface of the sampling box 6, the end surface of the threaded rod 37 is also fixedly connected to the end of the handle 2 33, and the rod end of the handle 2 33 passes through the inner wall of the sampling box 6, the threaded surface of the threaded rod 37 is threadedly connected to a threaded block 2 35, the other end of the threaded block 2 35 is rotatably connected to a spline sleeve 36, the end surface of the spline sleeve 36 is fixedly connected to a friction wheel 32, the inner wall of the spline sleeve 36 is slidably connected to a spline rod 1 38, the end of the spline rod 1 38 is rotatably connected to a fixed plate 2 39, the lower surface of the fixed plate 2 39 is also fixedly connected to the inner lower surface of the sampling box 6, and a motor 22 is arranged inside the sampling box 6, the output end of the motor 22 is belt-driven with the end of the spline rod 1 38;

[0056] The conical cylinder 23 has a surface that is rollingly connected to the surface of the friction wheel 32, a rotating rod 31 is fixedly connected to the large circular end of the conical cylinder 23, and the end of the rotating rod 31 is rotatably connected to the inner wall of the sampling box 6, and a spline rod 24 is fixedly connected to the small circular end surface of the conical cylinder 23, and the end surface of the spline rod 24 is also rotatably connected to the inner wall of the sampling box 6;

[0057] Gear ring 1 40, the inner wall of gear ring 1 40 is slidably connected to the surface of spline rod 24, the tooth surface of gear ring 1 40 is meshingly connected with gear ring 2 42, the inner wall of gear ring 2 42 is fixedly connected to the surface of drill tube 5, the end face of gear ring 1 40 is rotatably connected with connecting plate 41, the inner wall of connecting plate 41 is slidably connected to the surface of spline rod 24, and the other end of connecting plate 41 is rotatably connected to the surface of drill tube 5.

[0058] In this embodiment, rotating the second handle 33 can rotate the threaded rod 37, and further rotating the threaded rod 37 can drive the second threaded block 35 to move, so that the friction wheel 32 moves to different positions of the tapered tube 23. When the friction wheel 32 is close to the large circular end, the friction wheel 32 with the same rotation speed will cause the tapered tube 23 to rotate slower. When the friction wheel 32 is close to the small circular end, the rotation speed of the tapered tube 23 will become faster, thereby driving the second spline rod 24 to rotate at different speeds. The rotation of the second spline rod 24 will further drive the first gear ring 40 to rotate, and then drive the meshing second gear ring 42 to rotate, so that the drill tube 5 is rotated. Since the drill tube 5 is movable, the connection plate 41 is set, so that the first gear ring 40 is always meshed with the second gear ring 42, and the first gear ring 40 slides on the second spline rod 24 without affecting the rotation.

[0059] The speed regulating component is set to change the rotation speed of the drill tube 5 by turning the handle 2 33, so that when facing walls of different hardness, the speed of the drill tube 5 can be reasonably changed. When the wall is softer, the speed of the drill tube 5 is increased, and when the wall is hard, the speed of the drill tube 5 is reduced, thereby reducing the degree of damage to the wall by the drill tube 5 when sampling different wall surfaces, and also reducing the loss of the drill tube 5, further improving the practicality of the sampling device.

[0060] Embodiment 2, based on the above embodiment:

[0061] See also Figure 1 , Figure 2 and Figure 5 The material sampling device further comprises a push cleaning assembly, which is also arranged in the sampling box 6, and the push cleaning assembly comprises:

[0062] The piston plate 26, the piston plate 26 and the toggle rod 8, the upper surface of the sampling box 6 is provided with a sliding groove 7 that penetrates into the interior, the groove wall of the sliding groove 7 is slidably connected to the surface of the toggle rod 8, the lower surface of the toggle rod 8 is fixedly connected with a piston tube 16, and the end of the piston tube 16 close to the drill barrel 5 is fixedly connected to the end of the piston plate 26, a through groove is provided at the center of the piston plate 26, and a baffle 12 is hinged on the surface of the through groove, and the baffle 12 can only rotate toward the inside of the drill barrel 5.

[0063] In this embodiment, after sampling is completed, the drill tube 5 is restored, and then the toggle rod 8 is pushed to move. The movement of the toggle rod 8 drives the piston tube 16 to move. The movement of the piston tube 16 further drives the piston sheet 26 to move inside the drill tube 5, thereby pushing out the sample in the drill tube 5.

[0064] The setting of the push cleaning component makes it more convenient for the user to collect samples by using the piston plate 26 to push out the sample inside the drill barrel 5. In addition, since the drill barrel 5 moves during sampling, while the piston plate 26 does not move during sampling, the drill barrel 5 and the piston plate 26 will be disconnected during sampling, thereby making the rear end of the drill barrel 5 hollow, preventing the sample from extending into the drill barrel 5 during sampling, thereby increasing the internal pressure of the drill barrel 5 and making it difficult to continue to extend the drill barrel 5, thereby further improving the practicality of the sampling device.

[0065] Embodiment 3, based on the above embodiment:

[0066] See also Figure 2 , Figure 7 and Figure 8 The material sampling device also includes a knocking and vibrating component, which is also arranged in the sampling box 6, and the knocking and vibrating component includes:

[0067] The striking hammer 48 and the connecting plate 1 21, one end of the connecting plate 1 21 is fixedly connected to the end of the piston tube 16, the other end of the connecting plate 1 21 is fixedly connected to the connecting rod 2 14, the end of the connecting rod 2 14 away from the connecting plate 1 21 is fixedly connected to the pressing plate 13, the lower surface of the pressing plate 13 is fixedly connected to the connecting rod 3 55, the lower surface of the connecting rod 3 55 is fixedly connected to the straight tooth row 56, the tooth surface of the straight tooth row 56 is meshingly connected to the gear ring 3 54, the inner wall of the gear ring 3 54 is rotatably connected to the rotating rod 2 53, the surface of the rotating rod 2 53 is rotatably connected to the fixed plate 3 51, and the end surface of the fixed plate 3 51 is fixedly connected to the inner lower surface of the sampling box 6;

[0068] Rotating disk 57, the upper end surface of rotating disk 57 is fixedly connected to the lower surface of rotating rod 2 53, the lower end surface of rotating disk 57 is fixedly connected to fixed column 58, the surface of fixed column 58 is slidably connected to sliding frame 59, the side of sliding frame 59 is fixedly connected to curved rod 2 50, the other end of curved rod 2 50 is hinged to curved rod 3 49, the middle surface of curved rod 3 49 is provided with a penetrating strip groove, the groove wall of the strip groove is rotatably connected to curved rod 4 52, the upper surface of curved rod 4 52 is fixedly connected to the inner upper surface of sampling box 6, and the upper surface of curved rod 3 49 is also fixedly connected to the side of striking hammer 48.

[0069] In this embodiment, when the piston tube 16 is pushed to move, the connecting plate 1 21 will be further driven to move, and the movement of the connecting plate 1 21 will move the connecting rod 2 14, and the movement of the connecting rod 2 14 will make the pressing plate 13 move, thereby driving the connecting rod 3 55 to move, further driving the spur gear row 56 to move, and the movement of the spur gear row 56 will make the gear ring 3 54 rotate, thereby making the rotating rod 2 53 rotate, and then making the rotating disk 57 rotate, and the rotation of the rotating disk 57 will drive the fixed column 58 to slide in the sliding frame 59, thereby driving the reciprocating lateral movement of the curved rod 2 50, and then under the limiting action of the curved rod 4 52, the curved rod 3 49 will repeatedly swing, and during the swinging process, the curved rod 4 52 will slide up and down in the strip groove opened on the middle surface of the curved rod 3 49, thereby driving the percussion hammer 48 to knock on the surface of the drill tube 5, so that the surface of the drill tube 5 vibrates;

[0070] The setting of the percussion vibration component causes the surface of the drill barrel 5 to vibrate by striking the hammer 48, thereby enabling the sample to be better detached from the inside of the drill barrel 5, and further preventing the sample in the drill barrel 5 from adhering to the inner wall of the drill barrel 5, further facilitating the operator's sampling.

[0071] Embodiment 4, based on the above embodiment:

[0072] See also Figure 2 , Figure 5 , Figure 6 and Fig. 9The material sampling device also includes a blowing cleaning component, which is arranged inside the sampling box 6 and includes:

[0073] The gas collecting cylinder 15 and the fixing frame 46, the upper surface of the fixing frame 46 is fixedly connected to the inner upper surface of the sampling box 6, the side of the fixing frame 46 is fixedly connected to the side of the gas collecting cylinder 15, the inner wall of the gas collecting cylinder 15 is slidably connected with a piston 43, and the end of the piston 43 is fixedly connected to the end of the pressing plate 13;

The other end of the telescopic hose 20 is fixedly connected to the end of the piston tube 16 away from the drill tube 5.

[0077] In this embodiment, during the movement of the pressing plate 13, the piston 43 is driven to move. When the sample is taken out of the drill tube 5, the piston 43 moves away from the gas collecting cylinder 15 and the spring 44 is stretched. The gas collecting cylinder 15 inhales air into the interior through the air inlet pipe 17. After the sample is pushed out of the drill tube 5, the spring 44 causes the piston 43 to recover. Then, the gas in the gas collecting cylinder 15 is blown into the inside of the drill tube 5 through the telescopic hose 20. The wind is used to clean the sample remaining in the drill tube 5. In addition, during the recovery of the piston 43, the hammer 48 also strikes the surface wall of the drill tube 5, causing the drill tube 5 to vibrate.

[0078] The arrangement of the blowing cleaning component reduces the sample residue in the drill tube 5 by blowing air into the drill tube 5, thereby preventing the sample from being contaminated by a large amount of sample remaining in the drill tube 5 after multiple samplings.

[0079] Secondly, the drill tube 5 continues to vibrate during the blowing, so that the sample is not easily attached to the inner wall of the drill tube 5, thereby further improving the cleaning effect;

[0080] Thirdly, the provision of the spring 44 not only allows the piston 43 to return to its original position, but also makes it more difficult for the piston tube 16 to move when the toggle rod 8 is not pushed, thereby further improving the stability of the sampling device when in use.

[0081] Working principle: When the material sampling device for testing building exterior wall insulation materials is used, the following steps are performed:

[0082] S1: First, the height of the drill tube 5 is adjusted by the lifting mechanism, and then the sampling device is moved so that the collecting tank 4 is close to the wall;

[0083] S2: Then, according to the hardness of the wall, the handle 2 33 is turned to adjust the drilling speed of the drill tube 5, and then the motor 22 is started to rotate the drill tube 5;

[0084] S3: Then, turn the handle 1 3 to make the drill tube 5 inside the wall. After the sampling is completed, reverse the handle 1 3 to restore the drill tube 5.

[0085] S4: After that, the toggle rod 8 is pushed to move, and the sample in the drill tube 5 is pushed out by the piston plate 26. When the toggle rod 8 moves, it also drives the hammer 48 to knock the surface of the drill tube 5, so that the surface of the drill tube 5 vibrates;

[0086] S5: Finally, the toggle rod 8 is restored under the action of the spring 44, and the wind is blown toward the inside of the drill tube 5 to clean the samples inside the drill tube 5, and then the taken samples are collected.
