Description

Technical Field

[0001] The present invention belongs to the technical field of quality inspection of waterproof materials, and particularly relates to a quality inspection device for building waterproof materials. Background Art

[0002] Waterproof materials are used in the building envelope to prevent the penetration of rainwater, snowmelt, and groundwater; to prevent the erosion of moisture, steam, and other harmful gases and liquids in the air; and the partition structure to prevent the leakage of water supply and drainage. These materials for preventing penetration, leakage, and erosion are collectively referred to as waterproof materials. The main parts of a building that need waterproof treatment are the roof, walls, floors, and basements.

[0003] When the existing quality inspection equipment for building waterproof materials processes waterproof materials, it usually stores a certain amount of clear water on the surface of the waterproof materials to observe the permeability of the waterproof materials, and grinds the waterproof materials to a certain extent to detect their strength.

[0004] When the existing building waterproof materials are ground, the waterproof materials have a certain ductility, resulting in wrinkles during the grinding process, which in turn causes different degrees of surface wear of the waterproof materials and reduces the detection accuracy. At the same time, after the waterproof materials leak, the water flows along the surface of the waterproof materials, making it difficult to determine the leakage location. Summary of the Invention

[0005] The purpose of the present invention is to provide a quality inspection device for building waterproof materials, aiming to solve the technical problem that wrinkles are generated during the grinding of building waterproof materials in the prior art, which in turn causes different degrees of surface wear of the waterproof materials and reduces the detection accuracy.

A piston mechanism is arranged on the back of the workbench, and the piston mechanism can change the pressure in the sliding groove.

[0008] A transmission component is arranged between the piston mechanism and the support component. When the pressure in the chute decreases, the transmission component can drive the limiting frame to elastically abut against the end face of the workbench.

[0009] Further technical solution: The grinding mechanism includes a second electric rod, a frame, a sliding plate, a third telescopic rod, and a brush head.

[0010] The fixed end of the second electric rod is fixedly connected to the workbench. The telescopic end of the second electric rod is fixedly connected to a frame.

[0011] Further technical solution: The support component includes a support rod, a limiting sleeve, a convex platform, and a spring.

[0012] The support rod is fixedly connected to the convex platform. The workbench is fixedly connected with a limiting sleeve. The support rod slides through the limiting frame and the limiting sleeve, and a spring is connected between the limiting frame and the limiting sleeve. The spring is sleeved outside the support rod.

[0013] Further technical solution: The piston mechanism includes a fixing plate, a piston block, a fixing frame, and a fourth telescopic rod.

[0014] The back of the workbench is fixedly connected with a fixing frame. The fixed end of the fourth telescopic rod is fixedly connected to the fixing frame. The telescopic end of the fourth telescopic rod is fixedly connected to a fixing plate. The fixing plate is fixedly connected with a plurality of piston blocks.

[0015] Further technical solution: The transmission component includes a baffle and a bolt. One end of the baffle abuts against the fixing plate. The limiting sleeve penetrates and connects the other end of the baffle. The limiting sleeve is threadedly connected with a bolt, and the bolt abuts against the baffle.

[0016] Further technical solution: The winding mechanism includes a support frame, a first electric rod, a roller, and a motor.

[0017] The support frame is fixedly connected to the workbench. The fixed end of the first electric rod is fixedly connected to the support frame. The telescopic end of the first electric rod is rotatably connected to a roller. The roller is connected with a motor that drives it to rotate.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] 1. When the frame moves downward, the frame drives the push rod to press the limit frame, and the limit frame limits the waterproof material. The limit frame is divided into several ports by a partition plate in the middle. When the limit frame contacts the waterproof material, the waterproof material can be effectively positioned through the partition plate in the middle of the limit frame. When the slide plate drives the brush head to polish the surface of the waterproof material, large-area wrinkles on the waterproof material can be avoided;

[0026] 2. Arc-shaped baffles are provided on both side walls in the transverse direction of the port. The arc-shaped baffles can avoid grinding dead corners in the port and reduce the unevenness of the grinding area in the port. The collection grooves on both sides of the arc-shaped baffles can collect the grinding debris to avoid the debris accumulating on the waterproof coil and affecting the detection of the laser detector;

[0027] 3. When the waterproof material is attached to the end surface of the workbench, the fourth telescopic rod is started to contract at this time. When the fourth telescopic rod stops contracting, the air pressure in the chute stabilizes at a certain value, thereby generating an adsorption force on the waterproof material, and then further fixing the waterproof material on the end surface of the workbench. At this time, wrinkles on the waterproof material during the grinding process can be avoided, affecting the grinding uniformity of the waterproof material; In addition, the waterproof performance of the waterproof coil can be measured or partial area wear and rupture can be detected by the change of the air pressure value of the air pressure sensor.

[0028] 4. Pour clear water into the enclosure, and measure the waterproof performance of the waterproof material through the water leakage amount in each chute of the port. At the same time, the measurement result of the waterproof performance of the waterproof material can be further verified by the air pressure change in each chute of the port;

[0029] 5. Further, when the limit frame contacts the waterproof material, the partition in the limit frame can effectively separate and seal the waterproof material. The ports correspond one by one to the chutes in the annular sleeve. When the piston block slides in the chute, the partition in the limit frame can increase the fitting degree between the waterproof material and the end face of the workbench, avoiding gaps between the waterproof material and the workbench, thus causing poor sealing of the chute and affecting the test results.

[0037] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0038] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0039] As Figures 1 - 6As shown in the figure, a quality inspection device for a building waterproof material provided by the present invention includes a workbench 1. On the end face of the workbench 1, there is a surrounding wall 2. On the end face of the workbench 1, there are two winding mechanisms 3, and the winding mechanisms 3 can wind the waterproof material. Between the two winding mechanisms 3, there is a limiting frame 17. A support assembly 4 is connected between the limiting frame 17 and the workbench 1, and the support assembly 4 can elastically limit the limiting frame 17. Several ports 11 are separated in the middle of the limiting frame 17 by a partition. On the end face of the workbench 1, there are several air holes 8;

[0040] The workbench 1 is fixedly connected with a grinding mechanism 5, and the grinding mechanism 5 can grind the waterproof material on the workbench 1. On the back of the workbench 1, there is an annular sleeve 10. The annular sleeve 10 separates several sliding grooves. Each sliding groove is vertically aligned with the port 11, and the shape and area of the sliding groove and the port 11 are the same. Pressure sensors are arranged in the sliding grooves. On the back of the workbench 1, there is a piston mechanism 6, and the piston mechanism 6 can change the pressure in the sliding grooves;

[0041] A transmission assembly 9 is arranged between the piston mechanism 6 and the support assembly 4. When the pressure in the sliding groove decreases, the transmission assembly 9 can drive the limiting frame 17 to elastically abut against the end face of the workbench 1.

[0042] In this embodiment, when performing quality inspection on the waterproof material, first lay the waterproof material on the end face of the workbench 1, and then tighten the two ends of the waterproof material through the winding mechanisms 3; after the waterproof material is laid on the workbench 1, start the grinding mechanism 5. After the grinding mechanism 5 descends in height, it contacts and grinds the waterproof material on the workbench 1; at this time, under the downward pressure of the grinding mechanism 5, the limiting frame 17 further fixes the waterproof material. At the same time, the piston mechanism 6 can change the pressure in the sliding grooves, thereby generating an adsorption force on the waterproof material, and further fixing the waterproof material on the end face of the workbench 1. At this time, it can be avoided that the waterproof material has wrinkles during the grinding process, thereby affecting the grinding uniformity of the waterproof material;

[0043] After that, pour clear water into the surrounding wall 2, and measure the waterproof performance of the waterproof material through the water leakage amount in each sliding groove of the port 11. At the same time, the measurement result of the waterproof performance of the waterproof material can be further verified through the air pressure change in each sliding groove of the port 11.

[0044] As Figure 2 shown in the figure, a quality inspection device for a building waterproof material provided by the present invention, the grinding mechanism 5 includes a second electric rod 51, a frame 52, a sliding plate 53, a third telescopic rod 54, and a brush head 55;

[0045] The fixed end of the second electric rod 51 is fixedly connected to the workbench 1. The telescopic end of the second electric rod 51 is fixedly connected to a frame 52. A sliding plate 53 is slidably connected in the frame 52. A third telescopic rod 54 is connected between the sliding plate 53 and the frame 52. Multiple brush heads 55 are arranged on the sliding plate 53, and each brush head 55 faces a port 11. The frame 52 is fixedly connected to a push rod 7, and the push rod 7 can press the support assembly 4.

[0046] In this embodiment, the second electric rod 51 is started, and the second electric rod 51 drives the frame 52 to lower its height. The frame 52 drives the brush heads 55 to contact the waterproof material. Then, the third telescopic rod 54 is started, and the third telescopic rod 54 drives the sliding plate 53 to slide in the frame 52 through continuous telescopic movement. The sliding plate 53 drives the brush heads 55 to polish the surface of the waterproof material. The polishing efficiency of the surface of the waterproof material can be controlled by the telescopic amount of the second electric rod 51.

[0047] As Figure 3 shown, a quality inspection device for building waterproof materials provided by the present invention. The support assembly 4 includes a support rod 41, a limit sleeve 42, a boss 43, and a spring 44;

[0048] The support rod 41 is fixedly connected to the boss 43. The workbench 1 is fixedly connected to a limit sleeve 42. The support rod 41 slides through and penetrates the limit frame 17 and the limit sleeve 42, and a spring 44 is connected between the limit frame 17 and the limit sleeve 42. The spring 44 is sleeved outside the support rod 41.

[0049] In this embodiment, when the frame 52 moves downward, the frame 52 drives the push rod 7 to press the limit frame 17. The limit frame 17 limits the waterproof material, guides the support rod 41 through the limit sleeve 42, and elastically limits the limit frame 17 through the spring 44 at the same time.

[0050] As Figure 4 shown, a quality inspection device for building waterproof materials provided by the present invention. The piston mechanism 6 includes a fixing plate 61, a piston block 62, a fixing frame 63, and a fourth telescopic rod 64;

[0051] The back surface of the workbench 1 is fixedly connected to a fixing frame 63. The fixed end of the fourth telescopic rod 64 is fixedly connected to the fixing frame 63. The telescopic end of the fourth telescopic rod 64 is fixedly connected to a fixing plate 61. The fixing plate 61 is fixedly connected with a plurality of piston blocks 62. The piston blocks 62 are all slidably connected in the chutes in the annular sleeve 10. The end surface of the piston block 62 facing the workbench 1 is provided with a water collecting groove.

[0052] In this embodiment, when the waterproof material is attached to the end face of the workbench 1, the fourth telescopic rod 64 is started to contract at this time. The fourth telescopic rod 64 drives the fixed plate 61 to move downward, and the fixed plate 61 drives all the piston blocks 62 to slide downward in the sliding grooves in the annular sleeve 10. At this time, the air pressure in the sliding grooves decreases. When the fourth telescopic rod 64 stops contracting, the air pressure in the sliding grooves stabilizes at a constant value;

[0053] Air pressure sensors are arranged in the sliding grooves. The waterproof performance of the waterproof coiled material can be measured or the wear and rupture of some areas can be detected through the change of the air pressure value by the air pressure sensors.

[0054] As Figure 4 shown, a quality inspection device for building waterproof materials provided by the present invention. The transmission assembly 9 includes a baffle 91 and a bolt 92. One end of the baffle 91 abuts against the fixed plate 61, the limiting sleeve 42 penetrates and connects to the other end of the baffle 91, the limiting sleeve 42 is threadedly connected with a bolt 92, and the bolt 92 abuts against the baffle 91.

[0055] In this embodiment, when the fixed plate 61 moves vertically downward, the fixed plate 61 pushes the baffle 91 at this time. The baffle 91 abuts against the bolt 92, and the bolt 92 drives the support rod 41 to move vertically downward. At this time, the support rod 41 drives the convex platform 43 to push the limiting frame 17, and the limiting frame 17 vertically downward abuts against the end face of the workbench 1.

[0056] As Figure 3 shown, a quality inspection device for building waterproof materials provided by the present invention. The winding mechanism 3 includes a support frame 31, a first electric rod 32, a roller 33 and a motor 34;

[0057] The support frame 31 is fixedly connected to the workbench 1. The fixed end of the first electric rod 32 is fixedly connected to the support frame 31. The telescopic end of the first electric rod 32 is rotatably connected to a roller 33, and the roller 33 is connected to a motor 34 that drives it to rotate.

[0058] In this embodiment, the motor 34 is started, and the motor 34 can drive the roller 33 to rotate. The waterproof material can be tightened by the rotation of the roller 33. The first electric rod 32 is started, and the first electric rod 32 drives the roller 33 to descend in height, so that the waterproof material can abut against the end face of the workbench 1.

[0059] As Figure 5 shown, a quality inspection device for building waterproof materials provided by the present invention further includes a regulation system. The regulation system includes:

[0060] The monitoring module includes a plurality of laser detectors 14, all of the laser detectors 14 are fixedly connected to the limit frame 17. A through hole 15 is provided on the partition inside the limit frame 17, and the laser detector 14 can penetrate the opposite through hole 15. The laser detector 14 is used to monitor whether wrinkles occur on the surface of the waterproof material;

[0061] The processing module is used to receive the monitoring information in the monitoring module and form judgment information;

[0062] The control module receives the judgment information in the processing module and controls the rewinding mechanism 3, the grinding mechanism 5 and the piston mechanism 6.

[0063] As Figure 5 shown, a quality inspection device for building waterproof materials provided by the present invention. Arc-shaped baffles 12 are provided on both lateral side walls of the port 11, and the arc-shaped baffles 12 are connected to a collection groove 13.

[0064] Arc-shaped baffles 12 are provided on both lateral side walls of the port 11. Through the arc-shaped baffles 12, it is possible to avoid grinding dead corners in the port 11 and reduce the unevenness of the grinding area in the port 11. Through the collection grooves 13 on both sides of the arc-shaped baffles 12, the debris ground out can be collected, preventing the debris from accumulating on the waterproof coil and affecting the detection of the laser detector 14.

[0065] As Figure 6 shown, a quality inspection device for building waterproof materials provided by the present invention. A plurality of magnetic sliding sleeves 16 are slidably arranged on the bottom surface of the limit frame 17. The magnetic sliding sleeves 16 are all sleeved outside the port 11, and the magnetic sliding sleeves 16 can adsorb to the end face of the workbench 1; through the adsorption of the magnetic sliding sleeves 16 to the end face of the workbench 1, it is possible to more effectively partition between each port 11.

[0066] Working principle:

[0067] When conducting quality inspection on the waterproof material, first lay the waterproof material on the end face of the workbench 1, start the motor 34, and the motor 34 can drive the roller 33 to rotate. Through the rotation of the roller 33, the waterproof material can be tightened;

[0068] After the waterproof material is laid on the workbench 1, start the second electric rod 51. The second electric rod 51 drives the frame 52 to lower its height. The frame 52 drives the brush head 55 to contact the waterproof material. Then start the third telescopic rod 54. The third telescopic rod 54 drives the slide plate 53 to slide in the frame 52 through continuous telescopic movement. The slide plate 53 drives the brush head 55 to grind the surface of the waterproof material;

[0069] When the frame 52 moves downward, the frame 52 drives the push rod 7 to press the limit frame 17, and the limit frame 17 limits the waterproof material. A number of ports 11 are separated by partitions in the middle of the limit frame 17. When the limit frame 17 contacts the waterproof material, the partition in the middle of the limit frame 17 can effectively position the waterproof material. When the slide plate 53 drives the brush head 55 to polish the surface of the waterproof material, large-area wrinkles of the waterproof material can be avoided. At the same time, arc-shaped baffles 12 are arranged on both side walls in the transverse direction of the port 11. The arc-shaped baffles 12 can avoid grinding dead corners in the port 11 and reduce the unevenness of the grinding area in the port 11. The collecting grooves 13 on both sides of the arc-shaped baffles 12 can collect the debris ground out, avoiding the accumulation of debris on the waterproof coil and affecting the detection of the laser detector 14;

[0070] When the waterproof material is attached to the end face of the workbench 1, the fourth telescopic rod 64 is started to contract at this time. The fourth telescopic rod 64 drives the fixed plate 61 to move downward. The fixed plate 61 drives all the piston blocks 62 to slide downward in the chute in the annular sleeve 10. At this time, the air pressure in the chute decreases. When the fourth telescopic rod 64 stops contracting, the air pressure in the chute stabilizes at a certain value, thereby generating an adsorption force on the waterproof material, and further fixing the waterproof material on the end face of the workbench 1. At this time, wrinkles of the waterproof material during the grinding process can be avoided, and further affect the grinding uniformity of the waterproof material;

[0071] In addition, the waterproof performance of the waterproof coil can be measured or partial wear and rupture can be detected by the change of the air pressure value of the air pressure sensor.

[0072] Pour clean water into the enclosure 2, and measure the waterproof performance of the waterproof material by the water leakage amount in each chute in the port 11. At the same time, the measurement result of the waterproof performance of the waterproof material can be further verified by the air pressure change in each chute in the port 11;

[0073] Furthermore, when the limit frame 17 contacts the waterproof material, the partition in the limit frame 17 can effectively separate and seal the waterproof material. The ports 11 correspond to the chutes in the annular sleeve 10 one by one. When the piston block 62 slides in the chute, the partition in the limit frame 17 can increase the degree of fit between the waterproof material and the end face of the workbench 1, avoiding the appearance of gaps between the waterproof material and the workbench 1, thereby causing the chute to be poorly sealed and affecting the detection result;

[0074] At the same time, when the waterproof material leaks locally, at this time, through the separation of the limit frame 17, the leaked water flow can be prevented from flowing dispersedly along the surface of the waterproof material, so that the leakage area of the waterproof material can be determined more quickly.

[0075] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.

[0076] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
