Description

Technical Field

[0001] This invention relates to the field of building and shipbuilding material testing technology, and more specifically, to a high-sound-insulating floating floor strength testing device. Background Technology

[0002] High sound insulation floating floor is a building technology that effectively reduces the transmission of noise and vibration through physical isolation and sound absorption of materials. It is widely used in places with high sound insulation requirements such as ships, recording studios, residences, and gyms. Through elastic support or materials, such as rubber pads and spring systems, the floor is separated from the main building structure, cutting off the direct transmission path of sound waves and vibrations.

[0003] Chinese Announcement No. CN118641334B discloses a floor strength testing device, including a support base. An installation frame is fixedly connected to the upper side wall of the support base. A floor body is fixedly connected to the upper side wall of the support base via a clamping assembly. A first electric push rod is fixedly connected to the upper side wall of the installation frame. The clamping assembly and the first electric push rod are electrically connected in a forward circuit. A lifting plate is fixedly connected to the output end of the first electric push rod. An elastic cylinder is fixedly connected to the lower side wall of the lifting plate. This invention, during the testing of the compressive strength of flooring, can automatically adjust the compressive strength of the flooring according to its thickness, completely eliminating the need for manual adjustment by operators. This greatly simplifies the relevant steps of floor compressive strength testing and significantly improves the working efficiency of the testing device.

[0004] Although the aforementioned patent utilizes clamping components and lifting plates to automatically adjust the compressive strength of the floor according to its thickness, eliminating the need for manual adjustment, it is still necessary to ensure the overall strength and curvature of the floor during installation, in addition to basic strength testing, when testing high sound insulation floating floors, given the floor's elastic properties, to prevent deformation and damage under the pressure of heavy objects.

[0042] like Figures 5-7 As shown, a second electric telescopic rod 31 is fixedly connected to the top of the support frame 311. The output end of the second electric telescopic rod 31 is rotatably connected to the middle position of the sliding rod 32 through the support frame 311. Columns 321 are fixedly connected to the bottom of both ends of the sliding rod 32. Springs 322 are sleeved on the outer wall of the columns 321. A first sliding post 33 is provided at the end of the column 321 away from the sliding rod 32. The column 321 is telescopically connected to the top of the first sliding post 33. The first sliding post 33 is slidably connected to the inner wall of the support frame 311. A sliding strip 34 is fixedly connected to the bottom of the first sliding post 33.

A fixing strip 323 is fixedly connected to the bottom of the middle end of the sliding rod 32. A gear 3231 is rotatably connected to the inner side of the fixing strip 323 away from the sliding rod 32. The gear 3231 meshes with the racks 341 on both sides.

[0043] Wherein: the width of the first sliding column 33 is greater than the width of the support frame 311, and the limiting plate 123 is located at the top of the first sliding column 33 and is supported by the first sliding column 33.

[0044] like Figures 7-8As shown, the second sliding column 41 is in a vertically bent state. An irregular groove 411 is formed on the vertical surface of the second sliding column 41. The irregular groove 411 is composed of square grooves and circular grooves. The support frame 311 is fixedly connected to the top of the second sliding column 41. A height limiting column 412 is fixedly connected to the top of the second sliding column 41. The height limiting column 412 is matched with the position of the detection block 35 on one side. A baffle 413 is fixedly connected to one side of the height limiting column 412. A connecting strip 414 is fixedly connected to the side of the baffle 413 away from the height limiting column 412. An extension piece 42 is fixedly connected to the end of the connecting strip 414 away from the baffle 413. The extension piece 42 is fixedly connected to the top of the slider 211. The interior of the extension part 42 is hollow, and an extension plate is fixedly connected to the outside of the extension part 42. A threaded protrusion 43 is slidably connected to the outer wall of the rotating rod 23. The threaded protrusion 43 is located in the square groove of the irregular groove 411. A gear column 44 is rotatably connected in the circular groove of the irregular groove 411. The gear column 44 meshes with the threaded protrusion 43. A first connecting rod 441 is fixedly connected to one side of the gear column 44. A second connecting rod 442 is fixedly connected to the end of the first connecting rod 441 away from the gear column 44. The second connecting rod 442 is slidably connected through the slider 211. The end of the second connecting rod 442 away from the first connecting rod 441 is rotatably connected to the extension plate through a bent rod.

[0045] Among them, the extension part 42 is an extendable component, which can be referred to as the telescopic principle of umbrella ribs.

[0046] Therefore, when it is necessary to conduct a strength test on this high sound insulation floating floor, such as... Figure 4 As shown, during the preparation stage, the prepared floating floor is conveyed from one side of the device to the placement plate 2. At this time, the floating floor conveyed to the placement plate 2 is positioned by the surrounding plate 11, and the four corners of the square floating floor are respectively located on the extension member 42. After the position is correct, the inspection begins. Figures 5-7 As shown, driven by the first electric telescopic rod 122, the limiting plate 123 and the detection plate 1222 move down together to detect the pressure strength of the floating floor;

[0047] In addition, when it is necessary to conduct strength testing on the perimeter of the floating floor, such as Figure 5 As shown, driven by the second electric telescopic rod 31, the sliding rod 32 moves downward, simultaneously causing the first sliding posts 33, sliding bars 34, and detection blocks 35 on both sides to move downward together. At the same time, the downward movement of the sliding rod 32 also causes the fixed bar 323 and gear 3231 to move downward together. At this time, the gear 3231 will move downward at the same gear slot position as the rack 341 on the sliding bar 34, as... Figure 6As shown, when the right detection block 35 moves down to the top of the height-limiting column 412, it is blocked by the height-limiting column 412 and stops moving down. However, the left sliding column 33, which is continuously extended and moved down by the second electric telescopic rod 31, will continue to move down. At this time, the sliding rod 32 will tilt, causing the first sliding column 33 on the left side of the sliding rod 32 to move down until the left detection block 35 moves down to the top of the floating floor. At this time, the first electric telescopic rod 122 extends and drives the limiting plate 123 to move down. At this time, the limiting plate 123 will exert a downward force on the first sliding column 33, so that the detection block 35 performs strength testing on the periphery of the floating floor.

[0048] It should be noted that the lowest position that the limiting plate 123 can reach during the downward movement is the top of the first sliding column 33. At this time, the extension of the second electric telescopic rod 31 increases the pressure on the periphery of the floating floor. At the same time, the height difference between the bottoms of the two detection blocks 35 can be used to detect pressure of different thicknesses. That is, the thicker the floating floor, the greater the pressure it can withstand. Because when the second electric telescopic rod 31 moves down the same distance, that is, the thicker the floating floor, the higher the height of the first sliding column 33, and the greater the pressure of the first sliding column 33 on the limiting plate 123.

[0049] In addition, considering the inherent elasticity of high sound insulation floating floors, besides pressure strength testing, their bending resistance also needs to be tested to ensure the overall strength of the floating floor. Figures 7-8 As shown, under the drive of motor 111, threaded rod 24 rotates, which in turn drives rotating rod 23 to rotate. At this time, rotating rod 23 drives threaded protrusion 43 to rotate, and threaded protrusion 43 drives gear column 44 to rotate. This drives first connecting rod 441 to reciprocate and generate pulling and pushing forces on second connecting rod 442, causing second connecting rod 442 to push extension 42 upward and pull downward. When pushing upward, extension 42 will expand outward and raise the surrounding extension plates, so that the four corners of the floating floor are at the top of extension 42, and a certain distance is created between the middle position and the placement plate 2. At this time, second electric telescopic rod 31 extends and presses down detection plate 1222. At this time, the floating floor will bend to a certain extent under the interaction of extension 42 and detection plate 1222. This allows not only basic pressure strength testing of the floating floor, but also testing of its bending degree.

[0050] It should be noted that during the rotation of the threaded rod 24, it can also drive the second sliding column 41 to slide on the slide rail 22. Together with the gear column 44 through the first connecting rod 441 and the second connecting rod 442, the bending position can be adjusted. At the same time, the position of the pressure intensity detection in the surrounding area can also be adjusted, which can simulate the complex force situation in actual applications.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
