DETAILED DESCRIPTION

[0030] like Figures 1 to 10As shown, the measuring device 100 for a floor unit of an elevated floor of 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 has 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 of the left edge 1012 of the floor unit overlaps with the left reference line L12. The point overlaps with the left reference line L12. The first to sixth side length measuring devices 31, 32, 33, 34, 35, and 36 are located on the same plane and are arranged on the left, rear, and right sides of the floor unit 101. Because the front edge has the front reference line L11, there is no need to install a side length measuring device on the front side. By using the clamping mechanism 2 in conjunction with the first to sixth side length measuring devices 31, 32, 33, 34, 35, and 36, the four side lengths of the floor unit 101 under test can be accurately determined. This will be explained in detail below.

[0031] The first platform 1 can be a steel frame structure. Figures 2 to 9 It is simply illustrated with a flat plate.

[0032] 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.

[0033] 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.

[0034] The present invention is applicable to elevated floor units of various sizes. Before measurement, simply use a sample plate of standard dimensions to zero the first through sixth side length measuring devices 31, 32, 33, 34, 35, and 36. To facilitate explanation of the basic values, measured values, and calculation methods for the first through sixth side length measuring devices 31, 32, 33, 34, 35, and 36, a sample plate with four sides measuring 600 x 600 ± 0.1 mm is used as an example. After the sample plate is zeroed, the sample plate is removed and replaced with the test plate. If the measured values ​​for the four sides exceed ±0.1 mm, the four sides are deemed unqualified. Conversely, if the measured values ​​for the four sides are within ±0.1 mm, the four sides are deemed qualified. For example, if the first side length measuring device 31 measures +0.03 mm and the second side length measuring device 32 measures -0.01 mm, the sum of the two is +0.02, which is considered qualified. The values ​​of the third and fourth side length measuring devices, as well as the fifth and sixth side length measuring devices, are added together in the same manner to determine if the side lengths are qualified. This allows accurate measurement of the four sides of the floor unit 101, allowing for rapid verification of whether the four sides of the tested floor unit are within tolerance.

[0035] like Figure 4 As shown, the clamping mechanism 2 may further include a rear pushing mechanism 23 and a right pushing mechanism 24. The rear pushing mechanism 23 may be composed of two rear sliding roller seats 231, while 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, thereby securing the floor unit 101 for measurement, but also facilitates replacement of the floor unit 101 under test.

[0036] 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 the first to sixth side length measuring devices 31, 32, 33, 34, 35, 36 are of the same structure and are respectively arranged at different positions on the first platform 1. Figures 5 and 6 Only part of the structure is shown.

[0037] like Figure 5 As 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 6As 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.

[0038] like Figure 5 As shown, in order to facilitate the measurement and replacement of the floor unit, the first to sixth side length measuring devices 31, 32, 33, 34, 35, 36 may respectively include: a side length base 311, 321, 331, 341, 351, 361, fixed on the first platform 1, and having a slide rail 312, 322, 332, 342, 352, 362 on the side length base; a side length displacement meter 313, 323, 333, 343, 353, 363, slidably provided on the slide rail of the side length base; and a side length pneumatic cylinder 314, 324, 334, 344, 354, 364, driving the side length displacement meter along the slide rail to approach or move away from the floor unit.

[0039] like Figures 7 to 9 As shown, a four-legged height measuring device 41 may be provided on the first platform 1 . Figure 8 for Figure 7FIG2 is a partial enlarged view of the floor unit 101, wherein the front clamping structure is omitted for ease of illustration. This is identical to the clamping mechanism 2 described above. When measuring the four-leg height, after measuring the four sides, the first through sixth side length measuring devices 31, 32, 33, 34, 35, and 36 can be reset. At this point, the clamping mechanism 2 remains positioned and secured to the floor unit 101, allowing for continued four-leg height measurement at the same station. The four-leg height measuring devices 41 are suspended above the four corners of the floor unit 101 to measure the leg height H1 of each corner to obtain the four-leg height measurement values. Furthermore, to facilitate measurement and replacement of the floor unit 101, the first platform 1 may be further 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 mounted on the four cantilever support bases 42, 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 a four-leg height measuring device 41 disposed at the suspension ends 432 of the four cantilevers 43. Furthermore, the four-leg height measuring device 41 may employ a laser rangefinder 413 or a displacement meter (not shown) as a measuring device. 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 .

[0040] The pneumatic cylinder 411 comprises: a cylinder body 4111 fixed on the suspension end 432 of the cantilever, having an air pressure chamber 41111 inside thereof, an upper through hole 41112 communicating with the center of the top of the air pressure chamber 41111, a lower through hole 41113 communicating with the center of the bottom of the air pressure chamber 41111, an upper air valve 41114 communicating with the top of the air pressure chamber 41111, and a lower air valve 41115 communicating with the bottom of the air pressure chamber 41111; a rod body 4112 inserted into the A baffle 41121 that will not separate from the air pressure chamber 41111 is provided in the middle section of the rod body 4112 between the upper through hole 41112, the air pressure chamber 41111 and the lower through hole 41113 of the cylinder body 4111. When measuring the floor height, the rod body 4112 moves up and down in the air pressure chamber 41111 according to the different thickness of the floor. A laser rangefinder 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.

[0041] The fixing base 412 is fixed to the top of the pneumatic cylinder 411 and has an accommodating space 4121 . The laser ranging piece 41122 is disposed in the accommodating space 4121 so that the laser ranging piece 41122 can move up and down in the accommodating space 4121 of the fixing base 412 .

[0042] 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 the laser rangefinder 413 and the laser rangefinder sheet 41122 .

[0043] Before using the foot height measuring device 41 for measurement, a sample plate of standard dimensions is first zeroed. 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 the sample plate downward. The laser rangefinder 413 is then used to measure the distance between the laser rangefinder 413 and the laser rangefinder plate 41122, which is zero. This is the zeroing process. Next, 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 tested floor unit 101 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 four foot height measurements exceed ± 0.1 mm, the foot height is deemed unqualified. Conversely, if the four foot height measurements are within ± 0.1 mm, the foot height is deemed acceptable. Therefore, it is possible to accurately calculate whether the heights of the four legs of the floor unit 101 are qualified, and further to quickly complete the measurement of whether the leg heights of the tested floor unit are within the tolerance range.

[0044] 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 the top surface, thereby ensuring the accuracy of the measured foot height value.

[0045] In addition, a corner spacer 12 can be provided on the first platform 1 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 8 With the floor shown, the corner spacers 12 may not be used.

[0046] like Figure 10As 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.

[0047] The above embodiments of the present invention are only provided for the purpose of explanation and should not be used to limit the meaning of the present invention. That is, all kinds of modified designs based on the present invention should be included in the patent scope of the present invention.
