Description

Technical Field

[0001] This utility model belongs to the field of material testing technology, specifically relating to a surface testing device for flooring materials. Background Technology

[0002] Flooring materials refer to the paving or decorative materials used on the interior and surrounding surfaces of buildings, mainly including ceramic tiles, wood flooring, and stone. To ensure safety and prevent users from slipping and falling due to wet flooring surfaces, it is necessary to test the anti-slip properties of the flooring materials so that different anti-slip grades of flooring materials can be used in different application scenarios.

[0003] The inclined platform test is a test method recorded in relevant testing standards. It mainly involves having test personnel walk on an inclined sample while wearing test shoes. The anti-slip performance of the sample is evaluated by measuring the angle between the sample and the horizontal plane when the test personnel slip.

[0004] In related prior art, such as Chinese patent with announcement number CN212159510U, a foot-operated tile anti-slip performance testing device is disclosed. The solution includes a cabinet, with an inclined middle pad inside the cabinet, and a clamp on the cabinet that slides up and down along the upper surface of the middle pad. The above solution uses the clamp to abut against the upper end of the floor, clamping the floor between the front side of the cabinet and the clamp, thereby fixing the floor and ensuring the safety of the test.

[0005] The installation angle of the intermediate pad in the above scheme is fixed. During the experiment, it can only verify whether the experimenter slips when stepping on the sample at a single tilt angle, which is a relatively limited application scenario. Utility Model Content

[0006] The present invention aims to provide a surface inspection device for flooring materials to solve the problem that the above-mentioned solutions have limited applicable scenarios.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A surface inspection device for flooring materials includes a box, a frame, a support plate, and a fixing rod. The top of the box is open, and the frame has a through groove. The right end of the frame is rotatably connected to the inner wall of the box. Hydraulic push rods are rotatably connected to both sides of the left end of the frame, and the bottom of the hydraulic push rods is rotatably connected to the outer wall of the box. The support plate is slidably disposed in the groove and is connected to the frame through a limiting component. A stop block is fixedly disposed on the top of the right end of the support plate. The fixing rod is fixedly disposed on the top of the frame, and a pressure block is fixedly disposed on the left end of the bottom of the fixing rod.

[0008] The principle and effects of this technical solution: Initially, both the frame and the support plate are horizontal, and the limiting component is unlocked. During the experiment, the sample is placed on top of the support plate, and then the support plate is slid towards the pressure rod until the pressure block and the stop block press against the left and right ends of the sample respectively. At this time, the limiting component locks the support plate relative to the frame to prevent the support plate from shifting relative to the frame. Then, the experimenter, wearing test shoes, walks back and forth on the sample while continuously extending the hydraulic rod to push the frame, support plate, and sample to rotate. When the experimenter slips, the extension of the hydraulic rod is stopped, and the tilt angle of the frame is measured to evaluate the anti-slip performance of the sample surface.

[0009] By using the above settings to clamp the left and right ends of the sample with the pressure block and the stop block, the sample can be prevented from moving during the test, thus improving the safety of the device. By using the telescopic hydraulic push rod to drive the frame and the sample to rotate, the anti-slip performance of the sample surface can be evaluated, thus solving the problem of the limited applicability of the above-mentioned solutions.

[0010] In this invention, the top of the frame is fixedly provided with pressure bars arranged in the left-right direction at intervals, and the top of the support plate is provided with grooves at intervals opposite to each pressure bar. This arrangement prevents personnel from slipping on the sample and falling into the chamber, improving the safety of the device. Furthermore, by ensuring the bottom of the pressure bars contacts the inner wall of the grooves, the support plate is prevented from moving up and down after the pressure bars are fixedly installed.

[0011] In this utility model, guide rails are fixedly provided at the bottom of the front and rear inner sidewalls of the groove along their length, and toothed grooves are provided at the top of the two guide rails on the side closest to each other. The support plate is placed on top of the two guide rails, and the front and rear sidewalls of the support plate slide against the inner sidewall of the box. The bottom of the support plate is recessed above the toothed groove and has a sliding groove. The limiting component includes a limiting block that is slidably embedded in the sliding groove. The bottom of the limiting block is provided with a toothed groove engagement edge, and the top of the limiting block is rotatably connected to a screw. The screw is engaged and passes through the support plate.

[0012] The principle and effects of this technical solution: When the sliding support plate is in motion, the limiting block is located in the groove. After the pressure block and the stop block press the left and right ends of the sample respectively, rotate the screw threaded into the support plate to push the limiting block downward until the side wall of the bottom edge of the limiting block abuts against the side wall of the tooth groove. Because the pressure rod prevents the support plate from moving upward, the tooth groove prevents the limiting block and the support plate from moving to the right.

[0013] The above settings achieve the purpose of preventing the support plate from moving relative to the frame by using the limiting components.

[0014] In this invention, a shaft is fixedly installed at one end inside the housing, and connecting ears are fixedly installed on both sides of the right end of the frame. The connecting ears are rotatably fitted onto the shaft. A through groove is formed on the inner side wall of the housing, and the center line of the through groove is coplanar with the axis of the shaft. An indicator plate is provided at the bottom of the connecting ear near the through groove. Scale lines are arranged along the circumference of the shaft on the side of the connecting ear and the indicator plate near the through groove. When the frame rotation is paused, the scale aligned with the through groove on the indicator plate is read. Through the above arrangement, the tilt angle of the frame can be quickly measured, improving the working efficiency of this device during measurement.

[0015] This utility model also includes a watering assembly, which includes a water pipe and a water pump. The water pipe is fixedly installed horizontally on the right side of the fixing rod, and through holes are spaced apart on the radial sidewall of the water pipe. The water pump is fixedly installed inside the box, and the water pump is connected to one end of the water pipe through a flexible hose, while the other end of the water pipe is closed.

[0016] The principle and effects of this technical solution: In some testing projects, it is necessary for the test personnel to walk back and forth barefoot on the surface of the sample containing a flowing detergent solution. When conducting this type of test, water is first poured into the chamber to dissolve the detergent. Then, a water pump is used to pump the detergent solution in the chamber into the water pipe through a hose, and then let it flow out through the through hole, so that the detergent solution flows on the sample surface. The detergent solution flowing over the sample surface flows back into the chamber through the gap between the support plate and the frame.

[0017] The above setup allows researchers to conduct experiments using the water method, while also enabling the recycling of detergent solutions, thus saving water resources.

[0018] In this invention, brackets are fixedly installed on the top of the frame and on the front and rear sides of the groove, respectively, and a connecting rod is fixedly installed between the two brackets. This arrangement provides a support point for the safety belts and other protective equipment worn by the experimental personnel, further improving the safety of the device during use.

[0019] In this invention, footboards are fixedly installed on the top of the frame and on both the front and rear sides of the groove. This arrangement provides a point of leverage for the experimenter to move up and down the sample surface. Attached Figure Description

Hydraulic push rods 30 are rotatably connected to both sides of the left end of the frame 20. The bottom of the hydraulic push rods 30 is rotatably connected to the outer wall of the box 10. The support plate 40 is slidably disposed in the groove. Inside the body 21, the support plate 40 is connected to the frame 20 through a limiting component. A stop block 41 is fixedly installed on the top right end of the support plate 40. The fixing rod 50 is fixedly installed on the top of the frame 20, and a pressure block 51 is fixedly installed on the left end of the bottom of the fixing rod 50. The distance between the pressure block 51 and the support plate 40 is less than the thickness of the sample 100. The thickness of the stop block 41 is less than the thickness of the sample 100. The height difference between the top of the support plate 40 and the top of the frame 20 is greater than the thickness of the sample 100.

[0023] In this embodiment, the top of the frame 20 is fixedly provided with pressure rods 70 arranged in the left-right direction at intervals, and the top of the support plate 40 is provided with grooves 43 that are opposite to each pressure rod 70 at intervals. When the pressure rods 70 are fixedly installed on the frame 20, the bottom of the pressure rods 70 abuts against the inner bottom wall of the grooves 43.

[0024] In this embodiment, guide rails 22 are fixedly provided at the bottom of the front and rear inner sidewalls of the groove 21 along their length direction. The top of the two guide rails 22 on the side closest to each other is provided with toothed grooves 23. The support plate 40 is placed on top of the two guide rails 22. The front and rear sidewalls of the support plate 40 slide against the inner sidewall of the box 10. The bottom of the support plate 40 is recessed above the toothed grooves 23 and has a sliding groove 42. The limiting component includes a limiting block 61 that is slidably embedded in the sliding groove 42. The bottom of the limiting block 61 is provided with a ridge that engages with the toothed grooves 23. The top of the limiting block 61 is rotatably connected to a screw 62, which engages with the support plate 40.

[0025] In this embodiment, a shaft 11 is fixedly installed at one end of the box body 10, and connecting ears 24 are fixedly installed on both sides of the right end of the frame 20. The connecting ears 24 are rotatably sleeved on the shaft 11. A through groove 12 is opened on the inner side wall of the box body 10. The center line of the through groove 12 is coplanar with the axis of the shaft 11. An indicator plate 25 is provided at the bottom of the connecting ear 24 near the through groove 12. A scale line 26 is provided on the side of the connecting ear 24 and the indicator plate 25 near the through groove 12 along the circumference of the shaft 11.

[0026] In this embodiment, a watering assembly is also included, which includes a water pipe 81 and a water pump (not shown in the figure). The water pipe 81 is fixedly arranged laterally on the right side of the fixing rod 50. Through holes are provided at intervals on the radial sidewall of the water pipe 81. The water pump is fixedly arranged inside the housing 10, and the water pump is connected to one end of the water pipe 81 through a flexible hose 82. The other end of the water pipe 81 is closed, and the length of the flexible hose 82 between the water pump and the water pipe 81 is redundant.

[0027] In this embodiment, brackets 91 are fixedly installed on the top of the frame 20 on the front and rear sides of the groove 21, and a connecting rod 92 is fixedly installed between the two brackets 91.

[0028] In this embodiment, the top of the frame 20 is fixedly provided with pedals 93 on the front and rear sides of the groove 21, and the surface of the pedals 93 is provided with anti-slip protrusions.

[0029] The specific implementation process is as follows: In the initial state, both the frame 20 and the support plate 40 are horizontal, and the limiting component is unlocked. During the experiment, the sample 100 is placed on top of the support plate 40, and then the support plate 40 is slid towards the pressure rod 70 until the pressure block 51 and the stop block 41 press against the left and right ends of the sample 100 respectively. At this time, the limiting component locks the support plate 40 relative to the frame 20 to prevent the support plate 40 from shifting relative to the frame 20. Then, the experimenter walks back and forth on the sample 100 wearing test shoes, while continuously extending the hydraulic rod 70 to push the frame 20, the support plate 40, and the sample 100 to rotate. When the experimenter slips, the extension of the hydraulic rod 70 is stopped, and the tilt angle of the frame 20 is measured to evaluate the anti-slip performance of the sample 100 surface.

[0030] When the sliding support plate 40 is in motion, the limiting block 61 is located in the sliding groove 42. After the pressure block 51 and the stop block 41 press the left and right ends of the sample 100 respectively, rotate the screw 62 threaded into the support plate 40 to push the limiting block 61 downward until the side wall of the bottom edge of the limiting block 61 abuts against the side wall of the tooth groove 23. Because the pressure rod 70 prevents the support plate 40 from moving upward, the tooth groove 23 prevents the limiting block 61 and the support plate 40 from moving to the right.

[0031] In some testing projects, it is necessary for the test personnel to walk back and forth barefoot on the surface of the sample 100 with a flowing detergent solution. When conducting this type of test, water is first poured into the chamber 10 to dissolve the detergent. Then, a water pump is used to pump the detergent solution in the chamber 10 into the water pipe 81 through the hose 82, and then let it flow out through the through hole, so that the detergent solution flows on the surface of the sample 100. The detergent solution flowing over the surface of the sample 100 flows back into the chamber 10 through the gap between the support plate 40 and the frame 20.
