[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-10 The present invention provides a technical solution: a PVC floor wear resistance detection device and detection method, including a pretreatment mechanism 1, a detection mechanism 2, and a detection system. The pretreatment mechanism 1 is divided into an upper component 3 and a lower component 4. The upper component 3 is used to store and pre-treat sand particles, and the lower component 4 is used to pre-treat the floor. The upper component 3 and the lower component 4 respectively include a group of upper metal frames 5 and a lower metal frame 6, and the two groups of metal frames are combined together by welding;

[0030] A lower pretreatment bin 7 is welded on the lower metal frame 6, and a transport assembly 8 is arranged in the lower pretreatment bin 7. The transport assembly 8 includes two double plywoods 9 fixed on the bin wall of the lower pretreatment bin 7. A first rotating rod 10 is installed through the front ends of the two double plywoods 9. One end of the first rotating rod 10 is installed with a bearing on a board wall of a double plywood 9, and the other end is fixedly connected to the output end of a main motor 11 arranged on one side of the double plywood 9. A second rotating rod 12 is arranged at the rear ends of the two double plywoods 9, and both ends of the second rotating rod 12 are installed with bearings on the double plywoods 9. A chain 13 is arranged on the first rotating rod 10 and the second rotating rod 12. A bearing plate 14 is detachably installed on the chain 13. A corresponding number of bearing plates 14 are installed according to demand, and then the number of floors that can be pretreated each time is controlled. The transportation assembly 8 is used to control the transportation of the floors into or out of the lower pretreatment bin 7. The bearing plate 14 is a hollow plate, and the purpose is to make the floors loaded on the bearing plate 14 be pretreated more evenly;

[0031] Two camera assemblies 15 are arranged in the lower pretreatment chamber 7. Each camera assembly 15 is fixedly mounted on the inner chamber wall of the lower pretreatment chamber 7 through bolt holes on its surface. When installing, pay attention to aligning the camera port of the camera assembly 15 downwards to the floor. The flatness data of the floor surface is obtained through the camera assembly 15, and this data is determined as the initial flatness data.

[0032] A plurality of nozzles 16 are also arranged in the lower pretreatment bin 7, all of which are fixedly mounted on a mounting frame 17 welded to the inner wall of the lower pretreatment bin 7, each nozzle 16 sprays downward, an interface 18 is arranged on the top of each nozzle 16, a transverse main pipe 19 is arranged on the outer side of the lower pretreatment bin 7, one end of the transverse main pipe 19 is connected to the temperature control bin 20 through a sealed pipeline, a temperature sensor, a second heating pipe and a second cooling pipe are arranged in the temperature control bin 20, the temperature sensor is used to detect the temperature of the air in the temperature control bin 20, a plurality of vertical pipes 21 are arranged on the top of the temperature control bin 20, each vertical pipe 21 is connected to a nozzle 16 through a hose, so that the nozzle 16 is connected to the temperature control bin 20, independent valves are arranged at the connection between the temperature control bin 20 and each vertical pipe 21, all independent valves are controlled by the detection system to open and close, the other end of the transverse main pipe 19 is connected to the first row of delivery pipes 22 and The second row of delivery pipes 23, the first row of delivery pipes 22 are connected to the pumping machine, and the second row of delivery pipes 23 are connected to the exhaust machine. Both the exhaust machine and the pumping machine are prior art structures. The function of the exhaust machine is to extract the gas out of the lower pretreatment chamber 7, and the function of the pumping machine is to transport the gas into the lower pretreatment chamber 7. A multi-way intelligent valve 24 is arranged at the connection between the horizontal main pipe 19 and the second row of delivery pipes 23. The connection between the horizontal main pipe 19 and the first row of delivery pipes 22 and the second row of delivery pipes 23 is controlled by the multi-way intelligent valve 24. The multi-way intelligent valve 24 is adjusted and operated in time under the control of the detection system. A centralized storage barrel 25 is arranged between the horizontal main pipe 19 and the first row of delivery pipes 22. A first heating pipe and a first cooling pipe are arranged in the centralized storage barrel 25, and a reserved pipe 26 is arranged at the bottom of the centralized storage barrel 25. The function of the reserved pipe 26 is to be connected to the humidifier. The humidifier is a prior art device, and its function is to humidify the inside of the centralized storage barrel 25.

[0033] The detection system drives the air pump to operate, and the outside air is transported into the first row of delivery pipes 22 through the air pump, and then enters the centralized storage barrel 25 through the first row of delivery pipes 22. At this time, there are five operation processes inside the centralized storage barrel 25. The first is to open only the first heating pipe through the detection system, the second is to open only the first cooling pipe through the detection system, the third is to open only the humidifier through the detection system, the fourth is to open the first cooling pipe and the humidifier through the detection system, and the fifth is to open the first heating pipe and the humidifier through the detection system. The corresponding operation process and operation sequence are selected according to the detection standard of the floor. The role of pretreatment is to place the floor in a scene simulating the natural environment, so that the floor can reach or nearly reach the state after being used in the natural environment for a period of time through pretreatment, and then the pretreated floor is subjected to wear resistance testing, providing a variety of floors under different pretreatments for wear resistance testing, thereby improving Wear resistance inspection quality, the gas processed in the centralized storage barrel 25 enters the horizontal main pipe 19 through the multi-way intelligent valve 24, and enters the temperature control chamber 20 through the horizontal main pipe 19. The function of the temperature control chamber 20 is to detect the air pre-treated by the centralized storage barrel 25, and detect whether the temperature of the air entering the temperature control chamber 20 reaches the temperature value preset in the detection system. If it does not reach the temperature value preset in the detection system, the detection system drives the second heating pipe or the second cooling pipe to operate the air in the temperature control chamber 20 to process it again, ensuring that the air temperature entering the lower pretreatment chamber 7 reaches the temperature value preset in the detection system. If it reaches the temperature value preset in the detection system, the air enters the vertical pipe 21 through the temperature control chamber 20, then enters the interface 18, and finally enters the lower pretreatment chamber 7 through the nozzle 16, completing the process of the air entering the lower pretreatment chamber 7 after pretreatment;

[0034] The detection system drives the vacuum pump to operate. When the vacuum pump is operating, the lower pretreatment chamber 7 is connected to the second row of delivery pipes 23. The air in the lower pretreatment chamber 7 enters the vertical pipe 21 through the nozzle 16, then enters the temperature control chamber 20, and then enters the horizontal main pipe 19. Finally, it enters the second row of delivery pipes 23 through the multi-way intelligent valve 24 and is discharged into the vacuum pump, completing the cleaning of the air inside the lower pretreatment chamber 7, so that the next air that has been subjected to the operation process in the centralized storage barrel 25 can enter. Each time the lower pretreatment chamber 7 is pretreated, the vacuum pump needs to be used to clean the lower pretreatment chamber 7.

[0035] The floor pretreatment time is set in the detection system. When the pretreated floor reaches the pretreatment time, the floor is taken out manually.

[0036] A door 27 is provided at the front end of the lower pretreatment bin 7. The door 27 includes a door opening and closing groove 28 provided on the front wall of the lower pretreatment bin 7. Two rails 29 are fixedly installed on both sides of the door opening and closing groove 28. A half frame 30 is fixedly installed on the upper part of the two rails 29. A top plate 31 is fixedly installed on the top of the half frame 30. A hydraulic press 32 is fixedly installed on the bottom of the top plate 31. The output end bearing of the hydraulic press 32 is connected to a sealing door 33. The sealing door 33 is embedded in the two rails 29 and is slidably connected to the two rails 29. The hydraulic press 32 is driven to operate by the detection system. The operation of the hydraulic press 32 drives the sealing door 33 to rise and fall along the rails 29, and then the opening and closing of the door opening and closing groove 28 is realized by the sealing door 33, so that the lower pretreatment bin 7 pre-treats the floor in a relatively closed environment.

[0037] A sand storage bin 34 is welded on the upper metal frame 5. The sand storage bin 34 includes a plurality of grain feeding pipes 35 arranged on the rear side wall. Each grain feeding pipe 35 is provided with a micro valve 36. The function of the grain feeding pipe 35 is to transport sand into the sand storage bin 34. A conical bin 37 is welded on the top of the sand storage bin 34. A pump bin 38 is arranged on the top of the conical bin 37. The sand storage bin 34, the conical bin 37 and the pump bin 38 are internally connected. The purpose of arranging a plurality of grain feeding pipes 35 is to control the feeding speed and feeding amount of the sand, and also to avoid the situation where a single pipeline is blocked. The sand that has not been pretreated is in a loose state.

[0038] A plurality of heat conducting pipes 39 are arranged at the bottom of the sand storage bin 34, and the sand storage bin 34 is connected to the lower pretreatment bin 7 through the heat conducting pipes 39. A remote valve which can be controlled by the detection system is arranged in the heat conducting pipe 39, and a filter screen is arranged in the heat conducting pipe 39 to prevent the sand from entering the lower pretreatment bin 7. When the lower pretreatment bin 7 pretreatments the floor, the detection system opens the remote valve to connect the sand storage bin 34 with the lower pretreatment bin 7. The purpose is to make the temperature of the sand in the sand storage bin 34 consistent with the temperature of the floor pretreatment in the lower pretreatment bin 7 or have a small difference. The temperature of the pretreated floor is greatly different from the temperature of the natural environment. If the temperature of the used sand is greatly different from the temperature of the floor, the detection standard is not met, resulting in the inability to quantify the detection result due to the large temperature difference. The above-mentioned setting ensures that the factors of the sand itself will not affect the floor detection result.

[0039] A discharge pipe 40 is arranged on the side wall of the conical bin 37, and the discharge pipe 40 extends into the conical bin 37, and enters the sand storage bin 34 from the inside of the conical bin 37. A first delivery pump is arranged in the discharge pipe 40 arranged in the conical bin 37 and the sand storage bin 34, and is used to deliver the sand and discharge it. Part of the discharge pipe 40 is an elastic pipe, and part of it is a hard pipe. The whole discharge pipe 40 extends from the bottom of the lower pretreatment bin 7 to connect to the sand box. The sand box is an external structure for storing sand. The discharge pipe 40 has a large diameter. The purpose of the setting is that the sand that has been pretreated in the sand storage bin 34 will adhere to each other due to temperature changes, so as to avoid blockage when the sand is discharged;

[0040] The detection mechanism 2 includes a plurality of bases 41, each base 41 is welded with a wear-resistant detection chamber 42 on its top, a sand collection chamber 43 is welded on its top, and a protective shell 53 is welded on its top;

[0041] Three rows of wear-resistant cylinders 44 are arranged in the wear-resistant detection chamber 42, and each row of wear-resistant cylinders 44 is arranged with two. The bottom of the wear-resistant cylinder 44 is arranged as a supporting plate 45. A plurality of metal tubes 46 are evenly arranged on the edge and top of the supporting plate 45. Metal sleeves 47 are fixedly installed on the top of the plurality of metal tubes 46. Matching rotating grooves 48 are arranged in the sand gathering chamber 43 according to the arrangement of the wear-resistant cylinders 44. The bottom of the rotating groove 48 is detachably connected to the metal sleeves 47, and all the metal sleeves 47 can rotate in the rotating groove 48. When the wear-resistant cylinder 44 needs to be cleaned, the wear-resistant cylinder 44 can be pulled out of the rotating groove 48 by engagement. A motor assembly 49 is arranged at the bottom of the middle row of the three rows of wear-resistant cylinders 44, i.e., the middle two wear-resistant cylinders 44, and the output end of the motor assembly 49 is fixedly connected to the supporting plate 45.

[0042] A guide hole 50 is provided in the sand gathering bin 43, and the guide hole 50 is sealedly connected to the first conduit 51. The first conduit 51 is connected to the second conduit 52, and the second conduit 52 is connected to the pump bin 38. The second conduit 52 extends into the pump bin 38, and enters the sand storage bin 34 from the inside of the conical bin 37. A second delivery pump is provided in the second conduit 52 provided in the conical bin 37, the pump bin 38, and the sand storage bin 34, for delivering sand to be discharged. The detection system drives the second delivery pump to operate, so that the sand in the sand storage bin 34 enters the first conduit 51 through the second conduit 52, and then enters the sand gathering bin 43 through the guide hole 50. After the sand gathering bin 43 is filled, the sand enters the wear-resistant cylinder 44 through the rotating trough 48. Fill the wear-resistant cylinder 44 with sand particles on its surface. Sand particles protrude from the metal tubes 46. The protruding sand particles are used to rub the metal tubes 46. The sand particles used to test the floor here are slightly different in size, some are large and some are small. The sand particles can move freely in the wear-resistant cylinder 44. Therefore, when testing the floor, the floor will be tested uncontrollably with sand particles of different sizes, leaving different friction marks on the floor surface. Compared with a single friction device or a fixed friction process, the advantage of using sand particles for wear testing is that it can more naturally simulate the friction of the floor by the soles of shoes and other media in contact with the floor in the natural environment.

[0043] The first conduit 51 is sealedly connected to the guide hole 50 via the wear-resistant detection chamber 42. There is a bent portion in the wear-resistant detection chamber 42. The sand is transported from the bottom of the guide hole 50 into the sand collection chamber 43. The purpose of this transportation method is to accurately control the transportation amount of the sand. If the sand is directly transported from the side or top of the sand collection chamber 43, the sand retained in the first conduit 51 will press the sand in the sand collection chamber 43, and then the sand in the sand collection chamber 43 will press the sand in the wear-resistant cylinder 44, causing the sand in the wear-resistant cylinder 44 to protrude excessively, resulting in inaccurate floor wear test results.

[0044] An energy supply component 54 is arranged in the protective shell 53, and a heating component 55 and a cooling component 56 are arranged in the sand gathering bin 43. The energy supply component 54 is connected with the heating component 55 and the cooling component 56 to supply energy to the heating component 55 and the cooling component 56, and continuously maintain the temperature of the sand in the sand gathering bin 43, so that the temperature of the sand in the sand gathering bin 43 is maintained at the same temperature as the temperature of the floor pre-treated in the lower pre-treatment bin 7. Protective shells are arranged outside the heating component 55 and the cooling component 56 to prevent the sand from directly contacting the heating component 55 and the cooling component 56.

[0045] Adjacent wear-resistant inspection chambers 42 are connected by setting a sealed shell 57. The distance between adjacent wear-resistant inspection chambers 42 is very short, which has no effect on the inspection of the floor. The total length of the wear-resistant inspection chamber 42 can be extended or shortened by installing or disassembling the process according to the length of the floor. The front and rear wear-resistant inspection chambers 42 are both provided with metal doors 58. Open the metal doors 58, and insert the pre-treated floor vertically between the adjacent wear-resistant cylinders 44 (the gaps between the wear-resistant cylinders 44), and insert one from a gap in the front wear-resistant inspection chamber 42. A piece of floor is inserted into another piece of floor from another gap of the wear-resistant detection chamber 42 at the rear end. The rotating middle wear-resistant cylinder 44 moves the floor from the frontmost wear-resistant cylinder 44 to the rearmost wear-resistant cylinder 44 through rotation, and also moves the floor from the rearmost wear-resistant cylinder 44 to the frontmost wear-resistant cylinder 44. The moving process is also the process of wear-resistant detection of the floor. After the detection is completed, the floor surface is scanned and detected by a scanning device, and compared with the flatness data of the floor surface obtained by the camera component 15, and the final floor wear resistance detection result is judged by the detection system.
