DETAILED DESCRIPTION

[0014] The present invention will now be described in further detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0015] like Figure 1 The test device shown is used to detect the rolling load capacity of a floor, and comprises a base plate 1 and a support frame 2 arranged above the base plate 1 .

[0016] like Figure 1-Figure 5 As shown: In combination with the above content, in order to simulate the load distribution in different scenarios, so as to fully understand the performance of the floor under various complex conditions, a detection component 3 is also included which is arranged between the base plate 1 and the support frame 2; The detection component 3 includes a detection liquid cylinder 31 connected to the surface of the support frame 2 by screws, a lower pressure plate 32 fixed at the output end of the detection liquid cylinder 31, and a distance adjusting frame 34 fixed on the lower surface of the lower pressure plate 32. A movable slide group 35 is arranged inside the distance adjusting frame 34. The movable slide group 35 is composed of a plurality of groups of movable slides arranged at equal distances. Any two adjacent groups of movable slides are hinged with cross-arranged hinge rods 36, and detection rollers 37 are fixed to the lower surfaces of the plurality of groups of movable slides. Mobile bases 312 are symmetrically fixed on both sides of the surface of the bottom plate 1, and the support frame 2 is slidably connected between the two groups of movable bases 312 through slide rails. A detection seat 316 is fixed on one side of the surface of the bottom plate 1, a detection camera 317 is fixed on one side of the surface of the detection seat 316, and a light beam source 318 is fixed on the side of the surface of the detection seat 316 close to the detection camera 317.

[0017] In this embodiment: by starting the detection liquid cylinder 31, the output end of the detection liquid cylinder 31 pushes the lower pressure plate 32 to move downward, so that the lower pressure plate 32 can evenly transfer the pressure to the distance adjustment frame 34 and the detection roller 37 below, and apply a vertical load pressure to the floor. After the detection roller 37 contacts the floor surface, as the detection liquid cylinder 31 continues to apply pressure, the detection roller 37 generates a load on the floor surface, simulating the rolling load situation of the floor in actual use. Then, the detection camera 317 and the light beam source 318 cooperate to work. The light beam source 318 emits a straight light beam to illuminate the floor surface. The detection camera 317 continuously intercepts and collects the surface image of the floor under the rolling load of the detection roller 37. By analyzing the collected image, the maximum deformation of the bottom surface of the lower plate is recorded as the deflection of the rolling load. The surface condition of the floor can be intuitively observed, and the deformation condition, bearing capacity and other data of the floor under the rolling load can be obtained, thereby evaluating the rolling load capacity of the floor and realizing the performance of the floor under the rolling load.

[0018] It is worth noting that the detection roller 37 generates a load on the floor by applying pressure through the detection cylinder 31, which accurately simulates the vertical pressure that the floor bears in actual use. Whether it is light trampling in daily home use or frequent heavy pressure in commercial places, the device can reproduce the corresponding load scenario by adjusting the pressure of the detection cylinder 31, providing strong support for the performance evaluation of the floor in various practical application scenarios.

[0019] In an optional embodiment, the movable slide on one side of the movable slide group 35 is fixed inside the pitch-adjusting frame 34, and the movable slide surface on the other side of the movable slide group 35 is fixed with threaded blocks 38 on both sides, wherein the internal threads of one set of threaded blocks 38 are connected with threaded rods 39, and the threaded rods 39 are rotatably connected to one side of the pitch-adjusting frame 34, and the surface of the pitch-adjusting frame 34 is screwed with pitch-adjusting motors 310, and the output end of the pitch-adjusting motors 310 is fixedly connected to one end of the threaded rods 39, and the internal sliding connection of the other set of threaded blocks 38 is provided. There is a limit slide bar 311, and the limit slide bar 311 is fixed on one side of the distance adjustment frame 34, a moving tooth plate 315 is fixed on one side of the surface of the moving base 312, and the surface of the moving tooth plate 315 is meshed with a moving gear 314, the bottom surface of the support frame 2 is screwed connected to a moving motor 313, and the output end of the moving motor 313 is fixedly connected to the surface of the moving motor 313, and positioning columns 33 are fixed at the four corners of the surface of the lower pressure plate 32, and the positioning columns 33 are slidably connected to the positioning grooves opened inside the support frame 2.

[0020] In this embodiment: start the moving motor 313, and its output end drives the moving gear 314 to rotate. Since the moving gear 314 is meshed with the moving tooth plate 315 on the surface of the moving base 312, the rotation of the moving gear 314 drives the support frame 2 to move horizontally along the slide rail between the two sets of moving bases 312. By controlling the forward and reverse rotation and speed of the moving motor 313, the position of the support frame 2 can be accurately adjusted, thereby driving the lower pressure plate 32, the distance adjustment frame 34 and the detection roller 37 to move horizontally together, so that the detection roller 37 can be accurately positioned to the area on the floor that needs to be detected. Through the drive of the moving motor 313, the detection roller 37 can roll a certain distance and number of times on the floor surface, simulating the rolling load on the floor in actual use. The position of the detection roller 37 on the floor can be accurately adjusted to achieve targeted detection of different areas of the floor, improve the detection efficiency and coverage, and comprehensively evaluate the floor quality. When the spacing between the detection rollers 37 needs to be adjusted, the spacing motor 310 is started, and the output end of the spacing motor 310 drives the threaded rod 39 to rotate. When the threaded rod 39 rotates, the threaded block 38 connected to the threaded rod 39 moves along the surface of the threaded rod 39, thereby driving the moving slide connected to the threaded block 38 in the moving slide group 35 to move synchronously, so that except for the moving slide fixed inside the spacing adjustment frame 34 in the moving slide group 35, other moving slides move along the direction of the limiting slide rod 311 under the drive of the threaded rod 39. When the moving slide moves, the articulated rod 36 changes its angle with the movement of the moving slide. Through the linkage action of the articulated rod 36, the spacing between the multiple groups of moving slides changes, thereby realizing the adjustment of the spacing between the detection rollers 37. Therefore, according to the detection requirements of different floors, the spacing of the detection rollers 37 can be flexibly adjusted to simulate different rolling load distribution conditions.

[0021] It is worth noting that: the positioning column 33 slides in the positioning groove of the support frame 2 to ensure the vertical movement of the lower pressure plate 32, which enables the pressure to be evenly transmitted to the distance adjustment frame 34 and the detection roller 37, ensuring that the vertical load pressure applied to the floor is stable and evenly distributed. When testing floors of different materials, uniform pressure can avoid detection errors caused by excessive or insufficient local pressure, ensuring that the test results truly reflect the ability of the floor to withstand vertical loads, and improving the accuracy and reliability of the test.

[0022] Going further: In combination with the above content, in order to prevent the floor from shifting during the detection process, it also includes a fixing component 4 arranged directly below the detection roller 37, and the fixing component 4 includes a fixing frame 41 fixed to the surface of the base plate 1, and pressure plates 44 are symmetrically arranged on both sides of the interior of the fixing frame 41. Springs 45 are fixed between the two groups of pressure plates 44 and the fixing frame 41, and a clearance groove adapted to the pressure plate 44 is opened inside the fixing frame 41.

[0023] In this embodiment: when it is necessary to test the rolling load capacity of the floor, the floor to be tested is placed in the fixed frame 41. During the placement of the floor to be tested, both sides of the floor will contact and squeeze the two groups of pressure plates 44, so that the pressure plates 44 move toward the direction of the give way groove inside the fixed frame 41, thereby compressing the spring 45 to achieve the initial positioning of the floor in the fixed frame 41.

[0024] In an optional embodiment, push racks 46 are symmetrically fixed on opposite sides of the two groups of pressure plates 44, and the push racks 46 are slidably connected in a positioning slide fixed on the surface of the fixed frame 41, and the surface of the push racks 46 is meshedly connected with a transmission gear 47, and a transmission shaft 48 is fixed inside the transmission gear 47, and the transmission shaft 48 is rotatably connected to the surface of the fixed frame 41 through a bearing frame, and a bevel gear pair 49 is fixed at one end of the transmission shaft 48, and a screw rod 410 is coaxially fixed in the bevel gear of the bevel gear pair 49, and the screw rod 410 The second bearing frame is rotatably connected to the surface of the fixed frame 41, the surface of the screw rod 410 is threadedly connected with a moving block 411, and the moving block 411 is slidably connected in a moving groove opened inside the fixed frame 41, the surface of the moving block 411 is hinged with a push-pull hinge rod 412, and the other end of the push-pull hinge rod 412 is hinged with an extrusion plate 413, a positioning ear 414 is fixed on one side of the surface of the extrusion plate 413, a positioning rod 415 is fixed on the surface of the fixed frame 41, and the positioning ear 414 is slidably connected to the surface of the positioning rod 415.

[0025] In this embodiment: as the pressure plate 44 moves, it can drive the push rack 46 fixed on the opposite side thereof to slide in the positioning slide fixed on the surface of the fixed frame 41, thereby driving the transmission gear 47 to rotate, which can drive the transmission shaft 48 to rotate accordingly, and the bevel gear pair 49 at one end of the transmission shaft 48 transmits power to the screw rod 410, so that the screw rod 410 rotates synchronously, and the moving block 411 threadedly connected to the surface of the screw rod 410 slides in the moving groove opened inside the fixed frame 41 under the rotation of the screw rod 410, thereby driving the push-pull hinge rod 412 to drive the extrusion plate 413 to slide along the surface of the positioning rod 415 as the moving block 411 moves, thereby adjusting the position of the extrusion plate 413, further fixing the floor, and preventing the floor from being displaced during the detection process.

[0026] The working principle and use process of the present invention are as follows: when it is necessary to test the rolling load capacity of the floor, the floor to be tested is placed in the fixed frame 41. During the placement of the floor to be tested, the two sides of the floor will contact and squeeze the two groups of pressure plates 44, so that the pressure plates 44 move toward the direction of the give way grooves inside the fixed frame 41, and then compress the springs 45 to achieve the initial positioning of the floor in the fixed frame 41. During this period, as the pressure plates 44 move, the push racks 46 fixed on the opposite side thereof can be driven to slide in the positioning slide fixed on the surface of the fixed frame 41, thereby driving the transmission gear 47 to rotate, which can drive the transmission shaft 48 to rotate accordingly. The bevel gear pair 49 at one end of the transmission shaft 48 transmits power to the screw rod 410, so that the screw rod 410 rotates synchronously, and the movement of the threaded connection on the surface of the screw rod 410 As the screw rod 410 rotates, the block 411 slides in the moving groove provided inside the fixed frame 41, thereby driving the push-pull hinge rod 412 to drive the extrusion plate 413 to slide along the surface of the positioning rod 415 as the moving block 411 moves, thereby adjusting the position of the extrusion plate 413, further fixing the floor, and preventing the floor from being displaced during the detection process. At the same time, it can also more accurately detect the deformation and performance changes of the floor under the rolling load, achieve effective fixation, ensure that each floor can be stably and accurately fixed, and improve the reliability of the detection results. The stable and fixed floor effectively prevents the floor from being displaced during the detection process, ensures that the floor is fixed in position during detection, and ensures the stability and accuracy of the rolling load applied during the detection process, so that the detection data is true and reliable, improves the credibility of the detection results, and provides a reliable guarantee for floor quality detection.

[0027] Furthermore, after the floor to be tested is fixed, the detection liquid cylinder 31 is started, and the output end of the detection liquid cylinder 31 pushes the lower pressure plate 32 to move downward, and the positioning columns 33 fixed at the four corners of the surface of the lower pressure plate 32 slide in the positioning grooves provided inside the support frame 2, playing a guiding and stabilizing role, ensuring that the lower pressure plate 32 moves vertically downward, so that the lower pressure plate 32 can evenly transfer the pressure to the distance adjustment frame 34 and the detection roller 37 below, and apply a vertical load pressure to the floor. After the detection roller 37 contacts the surface of the floor, as The detection cylinder 31 continues to apply pressure, and the detection roller 37 generates a load on the floor surface, and then the moving motor 313 is started, and its output end drives the moving gear 314 to rotate. Since the moving gear 314 is engaged with the moving tooth plate 315 on the surface of the moving base 312, the rotation of the moving gear 314 drives the support frame 2 to move horizontally along the slide rail between the two sets of moving bases 312. By controlling the forward and reverse rotation and speed of the moving motor 313, the position of the support frame 2 can be accurately adjusted, thereby driving the lower pressure plate 32, The distance adjustment frame 34 and the detection roller 37 move horizontally together, so that the detection roller 37 can be accurately positioned at the area on the floor that needs to be detected. By driving the mobile motor 313, the detection roller 37 can roll a certain distance and number of times on the floor surface, simulating the rolling load of the floor in actual use. The position of the detection roller 37 on the floor can be accurately adjusted to achieve targeted detection of different areas of the floor, improve detection efficiency and coverage, and comprehensively evaluate the quality of the floor. The detection camera 317 and the light beam source 318 work together. The light beam source 318 emits a straight light beam to illuminate the floor surface. The detection camera 317 continuously intercepts and collects the surface image of the floor under the rolling load of the detection roller 37. By analyzing the collected image, the maximum deformation of the bottom surface of the board is recorded as the deflection of the rolling load. The surface condition of the floor can be intuitively observed, and the deformation condition, bearing capacity and other data of the floor under the rolling load can be obtained, so as to evaluate the rolling load capacity of the floor and realize the detection of the performance of the floor under the rolling load.

[0028] Furthermore, when it is necessary to adjust the spacing between the detection rollers 37, the spacing motor 310 is started, and the output end of the spacing motor 310 drives the threaded rod 39 to rotate. When the threaded rod 39 rotates, the threaded block 38 connected to the threaded rod 39 will move along the surface of the threaded rod 39, thereby driving the moving slides connected to the threaded block 38 in the moving slide group 35 to move synchronously, so that except for the moving slide fixed inside the spacing frame 34 in the moving slide group 35, the other moving slides move along the direction of the limiting slide 311 under the drive of the threaded rod 39. When the moving slide moves, the articulated rod 36 will change its angle with the movement of the moving slide. Through the linkage effect of the articulated rod 36, multiple groups of moving slides can be The spacing between the seats changes, thereby realizing the adjustment of the spacing between the detection rollers 37, so that according to the detection requirements of different floors, the spacing of the detection rollers 37 can be flexibly adjusted to simulate different rolling load distributions, significantly improving the detection efficiency. By adjusting the spacing of the detection rollers 37, the load distribution in these different scenarios can be simulated, so as to fully understand the performance of the floor under various complex conditions, so that the rolling load distribution of the floor during the detection process is closer to the actual situation, avoiding the detection error caused by the mismatch of the roller spacing, and the roller spacing can be adjusted according to the characteristics of the floor, so that the detection result is not affected by the unreasonable roller spacing, effectively improving the detection accuracy, and ensuring that each detection result can truly reflect the performance of the floor.

[0029] The above description only describes the specific implementation mode of the present invention. Various examples do not limit the essential content of the present invention. After reading the description, ordinary technicians in the relevant technical field can modify or deform the specific implementation modes described above without departing from the essence and scope of the invention.
