Description

Technical Field

[0001] The present invention relates to the technical field of material hardness detection, and in particular to a hardness detection device and method for a building curtain wall. Background Art

[0002] Hardness testing is usually not a single step in building curtain wall projects, but rather a process that runs through multiple key stages to ensure that each link meets quality requirements. Generally speaking, hardness testing is mainly carried out in the following steps:

[0003] During the raw materials arrival acceptance stage, before the materials are officially used, sampling inspections are carried out on raw materials such as curtain wall glass, aluminum profiles, and metal components.

[0004] During the quality control stage before factory processing, the hardness of the raw materials is reconfirmed before material processing.

[0005] During the post-installation acceptance phase, after the curtain wall installation is completed, the supervisor or third-party testing agency will usually conduct random inspections on some components.

[0006] Announcement No. CN214894624U discloses a glass curtain wall hardness testing device, comprising a fixed plate, the front surface of which is fixedly connected to a lower fixed seat, the inner right wall of which is fixedly connected to a bracket, the left surface of which is fixedly connected to a pressure sensor, the front surface of which is located above the lower fixed seat and is slidably connected to an upper fixed seat, the internal thread of which is connected to a locking pin, the front surface of which is located above the upper fixed seat and is fixedly connected to a mounting plate, the lower surface of which is fixedly connected to a sleeve, the inner side wall of which is fixedly connected to a limit block, the internal sliding connection of which is connected to a slide rod. The provision of the upper and lower fixed seats facilitates clamping the glass, thereby fixing the device, so that the device is no longer limited to the ground, making it convenient to test large glass curtain walls.

[0007] During the on-site acceptance of incoming raw materials and post-installation inspection, the testing method is typically determined based on the curtain wall material. Pencil hardness testing is commonly used for glass and protective films, while Rockwell, Vickers, or Brinell hardness tests are typically used for metals. Therefore, it's necessary to carry the appropriate testing equipment based on the curtain wall material being tested. When using a variety of curtain wall materials, multiple testing devices are often required to complete the curtain wall hardness test. Summary of the Invention

[0008] One of the purposes of the present invention is to provide a hardness detection device and method for building curtain walls, which determines the curtain wall material according to the feedback status of the curtain wall material to the detection device, and determines the corresponding detection method according to the curtain wall material to detect the curtain wall.

[0009] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0010] A first embodiment of the present invention provides a hardness detection device for a building curtain wall, comprising a detection head for contacting and marking the curtain wall surface, and a detector for measuring the detection head, wherein the detection head and the detector are connected by a wire.

[0011] In the above technical solution, there are multiple detection heads, and the detection heads are integrated inside the frame. The detection heads are parallel to the axial direction of the frame. During detection, the axis of the detection head is perpendicular to the surface of the curtain wall to be detected. A detection cavity is set at one end of the detection head facing the curtain wall, and a force-applying end is set inside the end of the detection head facing away from the detection cavity. The force-applying end applies a rated force to the detection head during the detection process.

[0012] In the above technical solution, a detection unit is configured inside the frame, and the detection unit obtains the material of the curtain wall when the frame contacts the curtain wall. The force-applying end applies different detection forces to the detection head according to the curtain wall material obtained by the detection unit.

[0013] In the above technical solution, the detection unit includes at least one material detection sensor, which is arranged toward the detected surface of the curtain wall and utilizes the energy difference of ultrasonic echo signals on surfaces of different materials to realize material identification.

[0014] In the above technical solution, a sleeve is provided on the outside of the frame body, and the sleeve can rotate relative to the frame body. A guide groove is provided on the surface of the frame body, and the guide groove is threaded. The inner wall of the sleeve extends toward its axial direction to form a positioning column and cooperates with the guide groove. The guide groove limits the movement path of the positioning column, and an elastic member is provided between the sleeve and the frame body for supporting the sleeve.

[0015] In the above technical solution, multiple storage grooves are opened on the inner wall of the sleeve, and the storage grooves are spirally arranged. A clamping plate is arranged inside the storage groove, one end of the clamping plate is fixed inside the storage groove, and the side of the clamping plate facing the storage groove is a cleaning structure, and the clamping plate supports the cleaning structure to extend toward the axis direction of the sleeve.

[0016] In the above technical solution, the storage groove is arranged in a spiral shape, and the card plate supports the cleaning structure to extend toward the axis. The card plate itself has a reset characteristic. In order to further extend the length of the card plate, it can extend to the middle position of the sleeve to cover the entire internal position of the sleeve, and when the sleeve moves, the card plate also needs to be stored. The detection head opens a groove corresponding to the position of the card plate. During the rotation of the sleeve, the groove and the card slot always correspond to each other, so that the card plate can be stored inside the storage groove.

[0017] In the above technical solution, the cleaning structure consists of two parts. The first part is a scraper located in the middle of the card plate. The scraper is flexibly set and always contacts the curtain wall surface during the rotation of the sleeve. The second part is bristles arranged on both sides of the scraper. The two sides of the end face of the card plate stored in the inner side of the storage groove are chamfered. The storage groove corresponds to the shape of the card plate, and the protrusion of the card plate cooperates with the groove.

[0018] In the above technical solution, the detection unit includes at least a curling edge installed on the outside of the frame, a driving member for driving the frame to move relative to the curtain wall, and a position sensor for obtaining the displacement of the frame.

[0019] In the above technical solution, the curled edge is surface-treated and generates friction between the curtain wall and the curtain wall when it contacts the curtain wall. When the telescopic part is driven with the same force, the displacement of the frame compared to the curtain wall is detected by the position sensor, and the friction between the curtain wall and the curled edge is determined based on the displacement of the frame.

[0020] In the above technical solution, the driving member is a top block, which also contacts the curtain wall when the curling edge contacts the curtain wall, and the friction between the top block and the curtain wall is greater than the friction between the curling edge and the curtain wall. A slide groove is arranged inside the frame, and a top plate extending into the inside of the slide groove is provided on one side of the top block and connected to the slide groove. An electromagnet is arranged between the top plate and the slide groove. The top plate is pushed outward by the cooperation of the electromagnet, thereby applying lateral displacement force to the top block.

[0021] In the above technical solution, an air pump is provided corresponding to the detection cavity, and the air pump is used to extract the air inside the detection cavity so that the frame can be adsorbed on the surface of the curtain wall.

[0022] In another technical solution, the driving part is an air pump, which is connected to the detection cavity and extracts the control inside the detection cavity. An air pressure sensor is set inside the detection cavity, and the curling edge contacts the curtain wall surface. The surface roughness of the curtain wall is determined according to the air pumping speed of the air pump and the air pressure change detected by the air pressure sensor.

[0023] In the above technical solution, the detection unit includes at least one brightness sensor for detecting light transmittance and a light source.

[0024] In the above technical solution, the detection unit includes at least one electromagnetic ring installed inside the frame. The electromagnetic ring passes through the electromagnetic attraction curtain wall. By obtaining the air pressure change inside the detection cavity, it is determined whether the electromagnetic ring magnetically attracts the curtain wall and the material of the curtain wall is determined.

[0025] In the above technical solution, the sleeve consists of two parts, including a cylinder and a cover plate, which are threadedly connected to each other. The clamping plate is restricted inside the receiving groove when the cylinder and the cover plate are threadedly connected. When the cylinder is disassembled, the clamping plate can be removed.

[0026] In the above technical solution, a box body is set at one end of the sleeve facing the curtain wall. The box body is confined inside the sleeve, and multiple through holes are opened at the bottom of the box body. A cavity is set inside the box body, and spring pieces are configured inside the sleeve to support the box body.

[0027] In the above technical solution, the interior of the box body is used to hold liquid for cleaning the curtain wall surface and cooperates with the cleaning structure. After the sleeve is subjected to downward pressure, the liquid inside the box body is sprayed out to cover the cleaning range of the cleaning structure. At the same time, the cleaning structure rotates to complete the cleaning of the curtain wall surface.

[0028] In the above technical solution, the outer side of the box body bulges outward, and the inner side of the sleeve is consistent with the outer contour of the box body. The bulge on the outer side of the box body restricts the box body so that the box body will not fall out.

[0029] A method for testing the hardness of a building curtain wall is used for testing the hardness of a building curtain wall using any of the above technical solutions. The method comprises the following steps:

[0030] Determine the location of the curtain wall to be inspected;

[0031] Start the detector and debug the detection device;

[0032] Place the frame against the surface to be tested so that it is perpendicular to the surface;

[0033] The testing unit determines the curtain wall material and determines the method for hardness testing;

[0034] The force-applying end applies the corresponding rated pressure to the corresponding detection head, and the detector measures the marks produced on the curtain wall surface to determine the surface hardness data of the curtain wall.

[0035] Through the above technical solution, the present invention has the following beneficial effects:

[0036] 1. When conducting surface hardness testing of curtain walls, this application determines the testing method according to different curtain wall materials and performs hardness testing on the curtain walls. When conducting acceptance of the curtain wall hardness, there is no need to carry corresponding hardness testing equipment according to the corresponding material of the curtain wall, which is more convenient for the inspector to perform the testing operation.

[0037] 2. Before conducting the hardness test, by cleaning the surface of the curtain wall to be tested, it is possible to avoid the presence of interference on the curtain wall surface, which may affect the results of the curtain wall hardness test, thereby improving the accuracy of the curtain wall hardness test. In addition, before the inspector conducts the test, there is no need to perform an additional surface cleaning on the curtain wall before conducting the hardness test.

[0038] 3. When determining the curtain wall material, the surface characteristics of the curtain wall are determined by determining its light transmittance, surface roughness, reflective state and whether it is magnetically attracted. Different detection heads are selected according to the surface characteristics of the curtain wall to detect the curtain wall surface to ensure the accuracy of the detection.

[0039] 4. The detachable cylinder makes it easy to disassemble the cardboard inside the cylinder during use, making it convenient to clean the cleaning structure on one side of the cardboard, thereby ensuring the cleaning effect of the cleaning structure on the curtain wall surface.

[0040] Other features and advantages of the present invention will be described in the following description, and part of them will become obvious from the description, or will be understood by practicing the present invention. The purpose and other advantages of the present invention can be realized and obtained by the structures particularly pointed out in the written description and the accompanying drawings.

[0066] First embodiment

[0067] See Figure 1-4 As shown, the first embodiment of the present invention proposes a hardness detection device for a building curtain wall, comprising a detection head 1 for contacting the surface of the curtain wall and marking the curtain wall, and a detector 2 for measuring the detection head 1, wherein the detection head 1 and the detector 2 are connected by a wire 3.

[0068] There are multiple detection heads 1, and the detection heads 1 are integrated inside the frame. The detection heads 1 are parallel to the axis of the frame. During detection, the axis of the detection head 1 is perpendicular to the surface of the curtain wall to be detected. A detection cavity 4 is set at one end of the detection head 1 facing the curtain wall, and a force-applying end is set inside the end of the detection head 1 facing away from the detection cavity 4. The force-applying end applies a rated force to the detection head 1 during the detection process.

[0069] When measuring the surface hardness of curtain walls, multiple detection heads 1 are integrated into the frame, enabling testing of different curtain wall materials. During the testing process, the detection heads 1 can be switched. Therefore, when testing curtain walls of various materials from the same batch, there is no need to replace the hardness detection device, and the testing of multiple curtain walls of the same batch can be completed. This further improves the convenience of curtain wall testing.

[0070] In a further implementation of the first embodiment, a detection unit 5 is configured inside the frame. The detection unit 5 obtains the material of the curtain wall when the frame contacts the curtain wall. The force-applying end applies different detection forces to the detection head 1 according to the curtain wall material obtained by the detection unit 5.

[0071] Since the acceptance of curtain walls needs to comply with the national standard for curtain wall hardness, different materials have different hardness requirements. Therefore, different detection heads 1 are set with different rated pressures. After determining the curtain wall material, the corresponding detection head 1 is determined according to the curtain wall material, and the corresponding pressure is applied. This can complete the detection of different materials without manual interference settings.

[0072] The detection unit 5 at least includes a material detection sensor 51 , which is disposed toward the detected surface of the curtain wall and utilizes the energy difference of ultrasonic echo signals on surfaces of different materials to identify the material.

[0073] The material detection sensor 51 is provided to accurately identify the type of material, and the detection method of the detection head 1 is determined according to the type of material.

[0074] Second embodiment

[0075] See Figure 5-8 As shown, the second embodiment of the present invention proposes a hardness detection device for a building curtain wall, including a detection head 1 that contacts the surface of the curtain wall and marks the curtain wall, and a detector 2 that measures the detection head 1, and the detection head 1 and the detector 2 are connected by a wire 3.

[0076] Among them, there are multiple detection heads 1, and the detection heads 1 are integrated inside the frame. The detection heads 1 are parallel to the axial direction of the frame. During detection, the axis of the detection head 1 is perpendicular to the surface of the curtain wall to be detected, and a detection cavity 4 is set at one end of the detection head 1 facing the curtain wall, and a force-applying end is set inside the end of the detection head 1 away from the detection cavity 4. The force-applying end applies a rated force to the detection head 1 during the detection process. Because its structure and the role it plays are the same as those in the first embodiment, its effect will not be described in detail in this embodiment.

[0077] In a further implementation of the second embodiment, a sleeve 61 is provided on the outside of the frame, and the sleeve 61 can rotate relative to the frame. A guide groove 62 is provided on the surface of the frame, and the guide groove 62 is threaded. The inner wall of the sleeve 61 extends toward its axial direction to form a positioning column 63 and cooperates with the guide groove 62. The guide groove 62 limits the movement path of the positioning column 63. An elastic member 64 is provided between the sleeve 61 and the frame to support the sleeve 61.

[0078] The sleeve 61 is used to protect the frame. When performing hardness testing, the sleeve 61 will first contact the curtain wall, and the frame will not directly contact the curtain wall. When the frame is pressed, the sleeve 61 will be displaced. At the same time, due to the restriction of the guide groove 62 on the positioning column 63, the sleeve 61 will move along the path of the guide groove 62.

[0079] Among them, a plurality of receiving grooves 65 are opened on the inner wall of the sleeve 61, and the receiving grooves 65 are spirally arranged. A clamping plate 66 is configured inside the receiving groove 65, and one end of the clamping plate 66 is fixed inside the receiving groove 65. The side of the clamping plate 66 facing the receiving groove 65 is a cleaning structure 67, and the clamping plate 66 supports the cleaning structure 67 to extend in the axial direction of the sleeve 61.

[0080] With the support of the clamping plate 66, the cleaning structure 67 is gathered in the middle and contacts the curtain wall. When in use, since the cleaning structure 67 contacts the curtain wall and the sleeve 61 can rotate, the cleaning structure 67 will also clean the surface of the curtain wall as the sleeve 61 rotates to ensure the inspection environment of the inspected curtain wall surface. There are no interferences on the inspection surface. While ensuring the inspection effect, there is no need for the inspector to perform additional cleaning of the curtain wall before measuring.

[0081] In addition, the storage groove 65 is set to be spiral, and the card plate 66 supports the cleaning structure 67 to extend toward the axis. The card plate 66 itself has a reset characteristic. In order to further extend the length of the card plate 66, it can extend to the middle position of the sleeve 61 to cover the entire internal position of the sleeve 61, and when the sleeve 61 moves, the card plate 66 also needs to be stored. The detection head 1 opens a groove corresponding to the position of the card plate 66. During the rotation of the sleeve 61, the groove and the card slot always correspond to each other, so that the card plate 66 can be stored inside the storage groove 65.

[0082] In a further implementation of the second embodiment, the cleaning structure 67 consists of two parts. The first part is a scraper 69 located in the middle of the card plate 66. The scraper 69 is flexibly set and always contacts the curtain wall surface during the rotation of the sleeve 61. The second part is bristles 610 arranged on both sides of the scraper 69. The card plate 66 is received in the receiving groove 65, and the two sides of the end face are chamfered 611. The receiving groove 65 corresponds to the shape of the card plate 66, and the protrusion of the card plate 66 cooperates with the groove.

[0083] Chamfers 611 are provided on both sides of one end face of the card plate 66. When the card plate 66 is stored, the groove restricts the card plate 66 and the position of the chamfer 611 cooperates with the storage groove 65 to guide the card plate 66, further increasing the stability of the card plate 66 during the storage process, avoiding the card plate 66 being forced into the storage groove 65 by squeezing, and preventing the card plate 66 from being worn by correction and positioning.

[0084] Third embodiment

[0085] See Figure 12-14 As shown, the third embodiment of the present invention proposes a hardness detection device for building curtain walls, including a detection head 1 that contacts the surface of the curtain wall and marks the curtain wall, and a detector 2 that measures the detection head 1, and the detection head 1 and the detector 2 are connected by a wire 3.

[0086] Among them, there are multiple detection heads 1, and the detection heads 1 are integrated inside the frame. The detection heads 1 are parallel to the axis of the frame. During detection, the axis of the detection head 1 is perpendicular to the surface of the curtain wall to be detected, and a detection cavity 4 is set at one end of the detection head 1 facing the curtain wall. A force-applying end is set inside the end of the detection head 1 away from the detection cavity 4. The force-applying end applies a rated force to the detection head 1 during the detection process. A detection unit 5 is configured on the inside of the frame. The detection unit 5 obtains the material of the curtain wall when the frame contacts the curtain wall. The force-applying end applies different detection forces to the detection head 1 according to the curtain wall material obtained by the detection unit 5. Because its structure and the role it plays are the same as those in the first embodiment, its effects will not be described in detail in this embodiment.

[0087] In a further implementation of the third embodiment, the detection unit 5 includes at least a curling edge 52 installed on the outside of the frame, a driving member 53 for driving the frame to move relative to the curtain wall, and a position sensor 54 for obtaining the displacement of the frame.

[0088] Among them, the curling edge 52 has been surface-treated and generates friction between the curtain wall and the curtain wall when it contacts the curtain wall. When the telescopic part is driven with the same force, the displacement of the frame compared to the curtain wall is detected by the position sensor 54, and the friction between the curtain wall and the curling edge 52 is determined based on the displacement of the frame.

[0089] In one of the feasible solutions, the driving member 53 is a top block 55, which also contacts the curtain wall when the curling edge 52 contacts the curtain wall, and the friction between the top block 55 and the curtain wall is greater than the friction between the curling edge 52 and the curtain wall. A slide groove 56 is arranged inside the frame, and a top plate 57 extending into the inside of the slide groove 56 is provided on one side of the top block 55 and connected to the slide groove 56. An electromagnet 58 is arranged between the top plate 57 and the slide groove 56. The cooperation of the electromagnet 58 pushes the top plate 57 to move outward, thereby applying a lateral displacement force to the top block 55.

[0090] The top plate 57 is used to push the top block 55 to move, so that the movement of the top block 55 generates a driving force for the frame, thereby prompting the frame to move. In addition, an air pump 59 is correspondingly provided in the detection chamber 4. The air pump 59 is used to extract the air inside the detection chamber 4 so that the frame can be adsorbed on the curtain wall surface.

[0091] In another feasible solution, the driving member 53 is an air pump 59, which is connected to the detection chamber 4 and extracts the control inside the detection chamber 4. An air pressure sensor 510 is set inside the detection chamber 4, and the curling edge 52 contacts the curtain wall surface. The surface roughness of the curtain wall is determined according to the suction speed of the air pump 59 and the air pressure change detected by the air pressure sensor 510.

[0092] The surface roughness of the curtain wall is determined as one of the parameters for determining the curtain wall material.

[0093] In a further implementation of the third embodiment, the detection unit 5 includes at least one brightness sensor 511 for detecting light transmittance and a light source 512 .

[0094] Among them, the light source 512 is fixed in the middle of the frame, and the brightness sensor 511 is set at the edge of the frame to obtain the brightness of the curtain wall. Since the light transmittance of curtain walls made of different materials is different, and the reflected light source 512 is also different under the illumination of the light source 512, the curtain wall material is further determined by detecting the light transmittance of the curtain wall when the light source 512 is not turned on and the reflected brightness when the light source 512 is turned on.

[0095] In a further implementation of the third embodiment, the detection unit 5 includes at least one electromagnetic ring 513 installed inside the frame. The electromagnetic ring 513 is capable of electromagnetically attracting the curtain wall. By obtaining the air pressure changes inside the detection cavity 4, it is determined whether the electromagnetic ring 513 is magnetically attracting the curtain wall and the material of the curtain wall is determined.

[0096] The material of the curtain wall can be further determined by measuring the surface roughness, light transmittance and reflective state of the material and whether the material can be magnetically attracted, so that pressure can be applied to the detection head 1 through the force-applying end to detect the curtain wall strength.

[0097] Fourth embodiment

[0098] See Figure 9-11 As shown, the fourth embodiment of the present invention proposes a hardness detection device for a building curtain wall, including a detection head 1 that contacts the surface of the curtain wall and marks the curtain wall, and a detector 2 that measures the detection head 1, and the detection head 1 and the detector 2 are connected by a wire 3.

[0099] Among them, the detection head 1 is multiple, and the detection head 1 is integrated into the frame. The detection head 1 is parallel to the axis of the frame. During detection, the axis of the detection head 1 is perpendicular to the surface of the curtain wall to be detected, and a detection cavity 4 is set at one end of the detection head 1 facing the curtain wall. A force-applying end is set inside the end of the detection head 1 away from the detection cavity 4. The force-applying end applies a rated force to the detection head 1 during the detection process. A sleeve 61 is set on the outside of the frame. The sleeve 61 can rotate relative to the frame. A guide groove 62 is set on the surface of the frame. The guide groove 62 is The sleeve 61 is arranged in a threaded shape, and the inner wall of the sleeve 61 extends toward its axial direction to form a positioning column 63 and cooperates with the guide groove 62. A plurality of receiving grooves 65 are provided on the inner wall of the sleeve 61. The receiving grooves 65 are spirally arranged. A clamping plate 66 is arranged inside the receiving groove 65, and the side of the clamping plate 66 facing the receiving groove 65 is a cleaning structure 67, and the clamping plate 66 supports the cleaning structure 67 to extend toward the axial direction of the sleeve 61. Because its structure and the role it plays are the same as those in the first embodiment, its effect will not be described in detail in this embodiment.

[0100] In a further implementation of the fourth embodiment, the sleeve 61 is composed of two parts, including a cylinder 71 and a cover plate 72, and the cylinder 71 and the cover plate 72 are threadedly connected, wherein the clamping plate 66 is restricted inside the receiving groove 65 when the cylinder 71 and the cover plate 72 are threadedly connected, and the clamping plate 66 can be removed when the cylinder 71 is disassembled.

[0101] The card plate 66 is arranged to be removable. After the hardness test of the curtain wall is completed, the card plate 66 can be taken out and the cleaning structure 67 can be cleaned, thereby ensuring the cleaning effect during multiple uses.

[0102] In addition, a box body 73 is set at one end of the sleeve 61 facing the curtain wall. The box body 73 is confined inside the sleeve 61, and a plurality of through holes 74 are opened at the bottom of the box body 73.
