Description

Technical Field

[0001] This utility model relates to the field of building quality testing technology, and in particular to a pull-out device for on-site testing of inorganic fiber spray coatings. Background Technology

[0002] In the construction, industrial, and many other fields, inorganic fiber spray coatings have been widely used due to their excellent performance. With the vigorous development of various industries, the quality and performance requirements for inorganic fiber spray coatings are becoming increasingly stringent, making testing a crucial step in ensuring compliance with standards and guaranteeing project quality. Accurate and reliable test results are directly related to the safety and stability of projects; therefore, efficient and precise testing technologies are essential for the industry's progress.

[0003] Existing testing is mainly carried out through a pull-out device fixed on a specific frame. Typically, the pull-out mechanism is installed in a specially designed frame structure, which serves to support and position the coating. When testing is required, the frame is first placed in a suitable position close to the inorganic fiber coating, and then the pull-out mechanism applies tension to the coating to complete the testing process.

[0004] Regarding the aforementioned technologies, once the fixed position and angle of the frame are determined, it is difficult to adjust. The connection and support method between the frame and the inorganic fiber spray coating is not flexible enough. When faced with coatings of different shapes and positions, such as on inclined walls and ceilings, the device cannot be flexibly adjusted according to the actual situation and cannot adapt to the coating detection needs of different shapes and positions, resulting in poor flexibility in the use of the device. Utility Model Content

[0005] To improve the flexibility of the device, this application provides a drawing device for on-site testing of inorganic fiber spray coatings.

[0006] This application provides a drawing device for on-site testing of inorganic fiber spray coatings, employing the following technical solution: A pull-out device for on-site testing of inorganic fiber spray coatings includes a triangular bracket. A fixing member is provided on the side of the triangular bracket near the inorganic fiber spray coating, passing through the inorganic fiber spray coating to support the triangular bracket. A pull-out assembly is provided inside the triangular bracket, and the triangular bracket and the pull-out assembly are detachably connected. A connecting plate is provided on the side of the pull-out assembly near the inorganic fiber spray coating, and the pull-out assembly is used to move the connecting plate. Several adhesive plates are provided on the side of the connecting plate near the inorganic fiber spray coating, and the adhesive plates are evenly distributed along the length of the connecting plate and slidably connected to the connecting plate along the width of the connecting plate. A replaceable adhesive film is provided on the side of the adhesive plate away from the connecting plate, and the adhesive film adheres to the inorganic fiber spray coating during testing.

[0007] By adopting the above technical solution, the triangular bracket supports the device, and the triangular bracket and the pulling component are detachably connected, making the device more convenient to transport, store, and switch between different testing scenarios. Testing personnel can quickly assemble or disassemble the device according to actual needs. The adhesive plate slides along the width of the connecting plate, facilitating adjustment of its position to better cover the testing area and ensure comprehensive and accurate testing. The replaceable adhesive film ensures adhesion performance for each test. After the adhesive film is tightly bonded to the inorganic fiber coating, the pulling component, through the connecting plate, drives the adhesive plate to apply force at a uniform speed, enabling the testing of the inorganic fiber coating. The fixing component passes through the inorganic fiber coating, reliably fixing the triangular bracket in the testing position, adaptable to inorganic fiber coatings of different thicknesses and materials. In actual testing scenarios, the device can test inorganic fiber coatings on flat walls or surfaces with a certain curvature or complex shapes, improving the flexibility of its use.

[0008] Optionally, the triangular bracket includes a disc and several support rods. The disc is located on the side of the connecting plate away from the adhesive plate, and the several support rods are located on the side of the disc close to the connecting plate. The several support rods are evenly distributed along the circumference of the disc, and the support rods are rotatably connected to the disc.

[0009] By adopting the above technical solution, the support rods are rotatably connected to the disc, and the unfolding angle and support direction of each support rod can be adjusted independently or synchronously according to the actual situation of the detection base surface, so that the device can maintain stable support under complex working conditions and improve the stability of the device.

[0010] Optionally, the fastener includes several insert rods, with a connecting rod at the end of the support rod away from the disc, the connecting rod being rotatably connected to the support rod, the insert rod being located at the end of the connecting rod away from the support rod, the insert rod being threadedly connected to the connecting rod, and a pointed end fixed at the end of the insert rod away from the connecting rod, the diameter of the pointed end gradually decreasing towards the end away from the connecting rod.

[0011] By adopting the above technical solution, the insertion rod and the connecting rod are connected by threads, which makes it easy to replace the insertion rod of different lengths according to the inorganic fiber coating of different thicknesses. The tip of the insertion rod adopts a diameter gradient design, with a small contact area and concentrated pressure, which can easily penetrate the loose structure of the inorganic fiber coating and reduce the resistance during insertion. The connecting rod and the support rod are rotatably connected, and the insertion direction can be adjusted synchronously with the unfolding angle of the support rod, improving the flexibility of the device.

[0012] Optionally, the pulling assembly includes a hydraulic cylinder, a pull rod, and a hanging ring. The hydraulic cylinder is located on the side of the disc near the connecting plate and is detachably connected to the disc. The pull rod is fixedly connected to the output end of the hydraulic cylinder. A hook is fixedly provided at the end of the pull rod near the connecting plate, and a hanging ring is fixedly provided on the side of the connecting plate near the pull rod. The hook is engaged with the hanging ring.

[0013] By adopting the above technical solution, the hydraulic cylinder, as a power source, can provide a stable and continuous pulling force. The hydraulic cylinder drives the connecting plate to move through the pull rod, and the movement of the connecting plate drives the adhesion plate to move, thereby realizing the detection of the inorganic fiber coating. The hook at one end of the pull rod is connected to the hanging ring on the connecting plate by a hooking method, which facilitates the connection between the pull rod and the connecting plate and improves the convenience of using the device.

[0014] Optionally, a display is fixed on the side of the disc away from the connecting plate, the display being used to show the tensile force value generated by the pulling assembly.

[0015] By adopting the above technical solution, the display can show the tensile force value generated by the pulling component in real time. During the pulling process, the tensile force value will be displayed on the display in real time, so that the testing personnel can quickly grasp the current tensile force status and improve the convenience of using the device.

[0016] Optionally, a slide rod is fixed on the side of the adhesive plate near the connecting plate. The slide rod passes through the connecting plate and is slidably connected to the connecting plate along the width direction of the connecting plate. A fixing nut is provided at the end of the slide rod away from the adhesive plate, and the fixing nut is threadedly connected to the slide rod.

[0017] By adopting the above technical solution, the slide rod is slidably connected to the connecting plate along the width direction of the connecting plate. The position of the adhesive plate can be adjusted by sliding the corresponding slide rod individually. After the adhesive plate is adjusted to the target position, tightening the fixing nut can lock the slide rod and the connecting plate, reducing the probability of the slide rod sliding accidentally.

[0018] Optionally, a protective cover is provided on the side of the connecting plate near the inorganic fiber coating, and the protective cover is detachably connected to the connecting plate.

[0019] By adopting the above technical solution, the protective cover forms a ring-shaped protective barrier around the connecting plate, which can effectively block the debris and dust splashed during the pulling process and improve the safety of on-site operations.

[0020] Optionally, a number of magnets are fixed inside the protective cover, and the magnets are evenly distributed around the circumference of the protective cover. Corresponding iron blocks are fixed on the outside of the connecting plate, and the magnets attract the iron blocks.

[0021] By adopting the above technical solution, several magnets are evenly distributed along the circumference of the protective cover, forming a multi-point adsorption and fixation with the corresponding iron blocks on the connecting plate. The adsorption force is evenly distributed, which allows the protective cover to fit tightly against the surface of the connecting plate, making it less prone to loosening or displacement. At the same time, it facilitates the disassembly and assembly of the protective cover, improving the convenience of using the device.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The fastener passes through the inorganic fiber coating layer, reliably fixing the tripod in the testing position, adaptable to inorganic fiber coatings of varying thicknesses and materials. In actual testing scenarios, the device can test inorganic fiber coatings on flat walls or surfaces with curvature or complex shapes, improving its flexibility of use. 2. Once the adhesive plate is adjusted to the target position, tighten the fixing nut to lock the slide rod and connecting plate, reducing the probability of accidental sliding of the slide rod and improving the stability of the device. 3. The protective cover forms a ring-shaped protective barrier around the connecting plate, which can effectively block the debris and dust that fly during the pulling process and improve the safety of on-site operations.

[0028] The present application will be further described in detail below with reference to all the accompanying drawings.

[0029] This application discloses a pull-out device for on-site testing of inorganic fiber spray coatings. Example

[0030] Reference Figure 1 and Figure 2A pull-out device for on-site testing of inorganic fiber spray coating 5 includes a disc 11 and several support rods 12. The support rods 12 are located on the side of the disc 11 closest to the inorganic fiber spray coating 5 and are rotatably connected to the disc 11. The unfolding angle and support direction of each support rod 12 can be adjusted independently or synchronously according to the actual conditions of the testing substrate, ensuring stable support even under complex working conditions and improving the stability of the device. The support rods 12 are evenly distributed around the circumference of the disc 11, providing support to the disc 11 and the entire support system from multiple directions, resulting in more even force distribution and further improving the stability of the support under complex stress environments.

[0031] Reference Figure 1 and Figure 2 A connecting rod 13 is provided at the end of the support rod 12 away from the disc 11, and an insertion rod 14 is provided at the end of the connecting rod 13 away from the support rod 12. During testing, the insertion rod 14 is inserted into the inorganic fiber coating 5 to support the device. The end of the insertion rod 14 away from the connecting rod 13 is fixed with a pointed part, the diameter of which gradually decreases towards the end away from the connecting rod 13. Due to the small contact area and concentrated pressure of the pointed part, the insertion rod 14 can easily penetrate the loose structure of the inorganic fiber coating 5 after contacting it, reducing the resistance during insertion and improving the ease of use of the device. The connecting rod 13 is rotatably connected to the support rod 12. Rotating the connecting rod 13 can adjust the direction of the insertion rod 14 into the inorganic fiber coating 5, improving the flexibility of the device. The insertion rod 14 is threadedly connected to the connecting rod 13. For inorganic fiber coatings 5 ​​of different thicknesses, simply rotate the insertion rod 14 to separate it from the connecting rod 13, and then replace it with an insertion rod of appropriate length, further improving the ease of use of the device.

[0032] Reference Figure 1 and Figure 3 A threaded rod is provided on the side of the disc 11 near the inorganic fiber coating layer 5. The threaded rod is threadedly connected to the disc 11. A hydraulic cylinder 2 is fixedly provided at the end of the threaded rod away from the inorganic fiber coating layer 5. A pull rod 21 is fixedly provided at the output end of the hydraulic cylinder 2. A connecting plate 4 is provided at the end of the pull rod 21 away from the threaded rod. Several adhesive plates 41 are provided on the side of the connecting plate 4 near the inorganic fiber coating layer 5. The adhesive plates 41 are evenly distributed along the length of the connecting plate 4. A replaceable adhesive film is provided on the side of the adhesive plate 4 away from the connecting plate 4. During the test, the adhesive film adheres to the inorganic fiber coating layer 5. After the adhesion is completed, the hydraulic cylinder 2 is started and the connecting plate 4 is moved through the pull rod 21. The movement of the connecting plate 4 causes the adhesive plates 41 to move, thereby realizing the test of the inorganic fiber coating layer 5.

[0033] Reference Figure 3 and Figure 4A hook 22 is fixed to one end of the pull rod 21 near the connecting plate 4, and a hanging ring 23 is fixed to the side of the connecting plate 4 near the pull rod 21. The hook 22 and the hanging ring 23 are engaged. The testing personnel only need to align the hook 22 with the hanging ring 23 and gently hook it on to complete the connection between the pull rod 21 and the connecting plate 4, without complicated operating procedures or additional tools. After the test is completed, the hook 22 can be quickly unhooked, which facilitates the disassembly and storage of the device and improves the convenience of using the device.

[0034] Reference Figure 3 and Figure 4 A sliding rod 42 is fixedly provided on the side of the adhesive plate 41 near the connecting plate 4. The sliding rod 42 passes through the connecting plate 4 and is slidably connected to the connecting plate 4 along the width direction of the connecting plate 4. The sliding rod 42 drives the connecting plate 4 to slide. By sliding the corresponding sliding rod 42 individually, the position of the adhesive plate 41 can be adjusted, which facilitates the detection of the inorganic fiber coating 5 in different areas. A fixing nut 43 is provided at the end of the sliding rod 42 away from the adhesive plate 41. The fixing nut 43 is threadedly connected to the sliding rod 42. When the adhesive plate 41 is adjusted to the target position, the fixing nut 43 can be rotated to lock the sliding rod 42 to the connecting plate 4, reducing the probability of the sliding rod 42 sliding accidentally.

[0035] Reference Figure 3 A switch 31 is fixedly installed at the end of the threaded rod away from the hydraulic cylinder 2. The switch 31 controls the hydraulic cylinder 2 to start. When testing the inorganic fiber coating 5, simply press the switch 31, and the hydraulic cylinder 2 will start to stretch the inorganic fiber coating 5, improving the ease of use of the device. A display 3 is fixedly installed at the end of the threaded rod near the switch 31. The display 3 can display the tensile force value generated by the pulling component in real time. During the pulling process, the tensile force value will be displayed on the display 3 in real time, allowing the tester to quickly grasp the current tensile force status and improving the ease of use of the device. At the same time, the display 3 calculates the bonding strength through the internal conversion program of the area of ​​the inorganic fiber coating 5 and the tensile force, and displays the calculation result synchronously on the display 3.

[0036] Reference Figure 3 and Figure 4 A protective cover 44 is provided on the side of the connecting plate 4 near the inorganic fiber spray coating 5. The inorganic fiber spray coating 5 is loose in texture and is prone to generating a large amount of debris and dust due to coating breakage during pull-out testing. If it splashes onto the operator's face, the protective cover 44 forms a ring-shaped protective barrier around the connecting plate 4, which can effectively block the debris and dust splashed during the pull-out process and improve the safety of on-site operations.

[0037] Reference Figure 3 and Figure 4The protective cover 44 is equipped with several magnets 45, which are evenly distributed around the circumference of the protective cover 44. The connecting plate 4 is equipped with corresponding iron blocks 46 on the outside. The magnets 45 and the corresponding iron blocks 46 form a multi-point adsorption fixation. The adsorption force is evenly distributed, which allows the protective cover 44 to fit tightly against the surface of the connecting plate 4, making it less prone to loosening or displacement. At the same time, it is easy to disassemble and assemble the protective cover 44, improving the convenience of using the device.

[0038] The implementation principle of a pull-out device for on-site testing of inorganic fiber spray coating 5 in this application embodiment is as follows: When testing the inorganic fiber spray coating on the ceiling or wall, rotate each support rod 12 to adjust the unfolding angle and support direction of each support rod 12, and then rotate the connecting rod 13 to adjust the direction of the insertion rod 14. The insertion rod 14 is then passed through the inorganic fiber spray coating 5, and the pull-out assembly performs a pull-out test on the inorganic fiber spray coating 5. Whether facing a flat wall surface or a surface with a certain curvature or complex shape, the support rod 12 can support the device, enabling the device to test the inorganic fiber spray coating 5 in different positions, thus improving the flexibility of the device.
