DETAILED DESCRIPTION
[0027] like Figures 1 to 9 As shown, the device 100 for measuring the foot height of a floor unit of an elevated floor according to the present invention comprises: a first platform 1; a clamping mechanism 2 disposed on the first platform 1 for clamping a floor unit 101 on the first platform 1; the clamping mechanism 2 having a front positioning structure 21 and a left positioning structure 22 to define a front reference line L11 and a left reference line L12 perpendicular to each other; a front edge 1011 of the floor unit 101 overlaps with the front reference line L11, and at least one point on the left edge 1012 of the floor unit overlaps with the left reference line L12; and four foot height measuring devices 41 suspended above the four corners of the floor unit 101 to measure the foot heights of the four corners of the floor unit 101 to obtain four foot height measurement values, thereby accurately determining the four foot heights of the measured floor unit 101. This will be described in detail below.
[0028] The first platform 1 can be a steel frame structure. Figures 2 to 7It is simply illustrated with a flat plate.
[0029] The front positioning structure 21 of the clamping mechanism 2 can be formed by two front fixed roller seats 211. The two front fixed roller seats 211 define a front reference line L11. The front edge 1011 of the floor unit 101 rests on the two front fixed roller seats 211, thereby overlapping with the front reference line L11. Furthermore, the left positioning structure 22 can be formed by two left fixed roller seats 221, which together define a left reference line L12 perpendicular to the front reference line L11. The left edge 1012 of the floor unit 101 rests on at least one of the left fixed roller seats 221, thereby causing at least one point on the left edge 1012 of the floor unit 101 to overlap with the left reference line L12.
[0030] The present invention ensures the shipping quality of floor units. Therefore, before measurement, it is assumed that the floor unit being measured is not necessarily square. Therefore, the left edge 1012 of the floor unit being measured may not necessarily be perpendicular to the front edge 1011. Therefore, the clamping mechanism 2 is designed so that, when the floor unit is positioned using the clamping mechanism 2, at least one point on the left edge 1012 of the floor unit 101 overlaps with the left reference line L12. Of course, if the left edge 1012 of the floor unit being measured is perpendicular to the front edge 1011, the front edge 1011 and left edge 1012 of the floor unit being measured will overlap with the front reference line L11 and the left reference line L12, respectively.
[0031] like Figure 4 As shown, the clamping mechanism 2 may further include a rear pushing mechanism 23 and a right pushing mechanism 24 to push the rear edge 1013 and right edge 1014 of the floor unit. The rear pushing mechanism 23 may be composed of two rear sliding roller seats 231, and the right pushing mechanism 24 may be composed of a right sliding roller seat 241. This structure not only ensures that the front edge 1011 of the floor unit 101 rests on the two front fixed roller seats 211 and the left edge 1012 of the floor unit 101 rests on at least one of the two left fixed roller seats 221, but also secures the floor unit 101 and facilitates replacement of the floor unit 101 under test.
[0032] like Figures 5 and 6 As shown, in this embodiment, the two front fixed roller seats 211 and the two left fixed roller seats 221 are of the same structure, the two rear sliding roller seats 231 and the right sliding roller seat 241 are of the same structure, and are respectively arranged at different positions on the first platform 1, so Figures 5 and 6 Only part of the structure is shown.
[0033] like Figure 5As shown, the two front fixed roller seats 211 and the two left fixed roller seats 221 can be respectively composed of a base 2111, 2211 and a roller 2112, 2212 rotatably mounted on the base. Figure 6 As shown, the two rear sliding roller seats 231 and the right sliding roller seat 241 can be respectively composed of a sliding rail base 2311, 2411 with a sliding rail 2312, 2412 on the top, a sliding base 2313, 2413 slidably mounted on the sliding rail base, a roller 2314, 2414 rotatably mounted on the sliding base, and a pneumatic cylinder 2315, 2415 that drives the sliding base 2313, 2413 along the sliding rail 2312, 2412 of the sliding rail base 2311, 2411 toward or away from the floor unit 101. With this structure, when the clamping mechanism 2 pushes the floor unit 101, friction damage to the surrounding of the floor unit 101 can be avoided.
[0034] like Figure 2 and Figure 7 As shown, four-leg height measuring devices 41 are disposed above the four corners of the first platform 1 to measure the leg height H1 of the four corners of the floor unit 101 to obtain the four-leg height measurement values. Furthermore, to facilitate the measurement and replacement of the floor unit 101, the first platform 1 may further be provided with: four cantilever support bases 42 disposed on the first platform 1 and located outside the four corners of the floor unit 101; four cantilevers 43, each having a pivot end 431 and a suspension end 432. The pivot ends 431 of the four cantilevers 43 are rotatably disposed on the four-leg height measuring devices 41, allowing the suspension ends 432 of the four cantilevers 43 to swing between above the four corners of the floor unit 101 and outside the floor unit 101; four swinging pneumatic cylinders 44, each driving the four cantilevers 43 to swing; and four-leg height measuring devices 41 disposed at the suspension ends 432 of the four cantilevers 43. Alternatively, the four-legged height measuring device 41 can employ a laser rangefinder 413 or a displacement meter (not shown). The laser rangefinder 413 is used as an example for the following description. The four-legged height measuring device 41 comprises a pneumatic cylinder 411, a fixing base 412, and a laser rangefinder 413.
[0035] like Figure 8As shown, the pneumatic cylinder 411 comprises: a cylinder body 4111, fixed on the suspension end 432 of the cantilever, with a pneumatic chamber 41111 inside, an upper through hole 41112 communicating with the center of the top of the pneumatic chamber 41111, a lower through hole 41113 communicating with the center of the bottom of the pneumatic chamber 41111, an upper air valve 41114 communicating with the top of the pneumatic chamber 41111, and a lower air valve 41115 communicating with the bottom of the pneumatic chamber 41111; a rod body 4112, inserted Between the upper through hole 41112 of the cylinder body 4111, the air pressure chamber 41111 and the lower through hole 41113, a baffle 41121 is provided in the middle section of the rod body 4112 so as to not separate from the air pressure chamber 41111. When measuring the floor height, the rod body 4112 moves up and down in the air pressure chamber 41111 according to the different thicknesses of the floors. A laser ranging plate 41122 is provided at the top end of the rod body 4112, and a floor fixing plate 41123 is provided at the bottom end of the rod body 4112.
[0036] The fixing seat 412 is fixed on the top of the pneumatic cylinder 411 and has an accommodating space 4121. The laser (laser) ranging piece 41122 is set in the accommodating space 4121 so that the laser (laser) ranging piece 41122 can move up and down in the accommodating space 4121 of the fixing seat 412.
[0037] The laser rangefinder 413 is disposed at the top of the accommodating space 4121 of the fixing base 412 and can measure the distance H2 between it and the laser rangefinder piece 41122 .
[0038] Before using the foot height measuring device 41 for measurement, a sample plate of standard dimensions is first used for zeroing. Specifically, after positioning the sample plate using the clamping mechanism 2, the pneumatic cylinder 411 is activated, causing the floor fixing plate 41123 to press downward against the sample plate. The laser rangefinder 413 is then used to measure the distance between the laser rangefinder 413 and the laser rangefinder plate 41122, ensuring that the distance is zero. This is the zeroing process. After replacing the floor unit 101 to be tested, the distance between the laser rangefinder 413 and the laser rangefinder plate 41122 is again measured to determine whether the foot height of the floor unit 101 being tested meets the requirements. This is explained below using a sample plate with a foot height of 60±0.1 mm as an example. After zeroing the sample plate, the sample plate is removed and replaced with the test plate. If the measured values for the four-foot height exceed ±0.1mm, the height is deemed unacceptable. Conversely, if the measured values for the four-foot height are within ±0.1mm, the height is deemed acceptable. This allows accurate calculation of the acceptable height of the four-foot height of the floor unit 101 and allows for rapid verification of whether the height of the floor unit under test is within tolerance.
[0039] In addition, the distance between the laser rangefinder and the top surface of the floor unit can also be measured directly with a laser rangefinder without using components such as the pneumatic cylinder 411 (not shown in the figure). However, since the foot height portion of the floor unit often has structures such as locking holes or ventilation holes, the method of pressing the floor unit 101 with the floor fixing plate 41123 and then measuring the laser rangefinder plate 41122 can ensure that the laser rangefinder 413 will not measure structures such as locking holes or ventilation holes that are not on the top surface, thereby ensuring the accuracy of the measured foot height value.
[0040] like Figure 7 As shown, on the first platform 1, a corner spacer 12 can be provided at each of the four corners of the groove floor unit 101, so that when measuring the floor, the four corners of the floor unit 101 are all located on the same horizontal plane of the platform. The corner spacers 12 can be used with a variety of different groove floor units 101 to accommodate floor units of different heights. In addition, the top surface 121 of the corner spacer 12 can be smooth to prevent the bottom of the floor unit from being worn when the clamping mechanism 2 pushes the floor unit 101. However, the four corners of the floor unit have convex shapes, such as Figure 7 With the floor shown, the corner spacers 12 may not be used.
[0041] like Figure 9 As shown, to save manpower, the present invention may further include: a second platform 5, located in front of the first platform 1; a third platform 6, located behind the first platform 1; and a transport mechanism 7, which further includes: a support frame 71, which sets a transport rail 72 above the first platform 1, the second platform 5, and the third platform 6; and at least one gripping mechanism 73, which is located on the transport rail 72 and can move along the transport rail 72 to grip and transport the floor unit 101 between the first platform 1, the second platform 5, and the third platform 6. In this embodiment, two gripping mechanisms 73 are used. While the first gripping mechanism 73 is transporting the measured floor unit to the third platform 6, the second gripping mechanism 73 can simultaneously transport the floor unit to be tested on the second platform 5 to the first platform 1. This not only reduces the standby time of the measurement equipment and thereby increases overall work efficiency, but also facilitates automated operations.

That is, all kinds of modified designs based on the present invention should be included in the patent scope of the present invention.
