DETAILED DESCRIPTION

[0030] like Figures 1 to 10As shown, the measuring device 100 of the floor unit of the elevated floor of the utility model comprises: a first platform 1; a clamping mechanism 2, which is arranged on the first platform 1 and clamps 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; the front edge 1011 of the floor unit 101 overlaps with the front reference line L11, and at least the left edge 1012 of the floor unit The first side length measuring device to the sixth side length measuring device 31, 32, 33, 34, 35, 36 are located in the same plane and arranged on the left, rear and right sides of the floor unit 101. Since there is a front reference line L11 at the front edge, it is not necessary to set a side length measuring device on the front side. The clamping mechanism 2 cooperates with the first side length measuring device to the sixth side length measuring device 31, 32, 33, 34, 35, 36 to accurately know the lengths of the four sides of the floor unit 101 under test. This will be described in detail below.

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

[0032] The front positioning structure 21 of the clamping mechanism 2 may be composed of two front fixed roller seats 211. The two front fixed roller seats 211 form a front reference line L11. The front edge 1011 of the floor unit 101 leans against the two front fixed roller seats 211, thereby overlapping with the front reference line L11. In addition, the left positioning structure 22 may be composed of two left fixed roller seats 221, and the two left fixed roller seats 221 form a left reference line L12 perpendicular to the front reference line L11. The left edge 1012 of the floor unit 101 at least leans against one left fixed roller seat 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 utility model can ensure the delivery quality of the floor unit, so it is assumed before measurement that the floor unit to be tested is not necessarily square, so there is a situation that the left edge 1012 of the floor unit to be tested is not necessarily perpendicular to the front edge 1011. Therefore, the clamping mechanism 2 is designed to make at least one point on the left edge 1012 of the floor unit 101 overlap with the left reference line L12 when the floor unit is positioned by the clamping mechanism 2. Of course, if the left edge 1012 of the floor unit to be tested is perpendicular to the front edge 1011, the front edge 1011 and the left edge 1012 of the floor unit to be tested will overlap with the front reference line L11 and the left reference line L12 respectively.

[0034] The utility model is applicable to floor units of elevated floors of various sizes. Before measurement, a sample plate that meets the standard size is taken to perform zeroing operations on the first to sixth side length measuring devices 31, 32, 33, 34, 35, 36. In order to conveniently explain the basic values, measurement values ​​and calculation methods of the first to sixth side length measuring devices 31, 32, 33, 34, 35, 36, a sample plate with four sides of 600x600±0.1mm is used as an example for explanation as follows. After the sample plate is reset to zero, the sample plate is removed and replaced with the plate to be tested. If the measured values ​​of the four sides exceed ±0.1mm, the four sides are judged to be unqualified. On the contrary, if the measured values ​​of the four sides are within ±0.1mm, the four sides are judged to be qualified. For example, the first side length measuring device 31 measures +0.03mm, and the second side length measuring device 32 measures -0.01mm. The sum of the two is +0.02, which is judged to be qualified. The measured values ​​of the remaining third and fourth side length measuring devices and the fifth and sixth side length measuring devices are also added in the same way to determine whether the side length is qualified. Therefore, it is possible to accurately measure whether the four sides of the floor unit 101 are qualified, and then quickly complete the measurement of whether the four sides of the tested floor unit are within the tolerance range.

[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, and the right pushing mechanism 24 may be composed of a right sliding roller seat 241. With this structure, it is possible to ensure 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, and the floor unit 101 is fixed for measurement, and the floor unit 101 to be measured can also be easily replaced.

[0036] like Figure 5-6 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 side length measuring device to the sixth side length measuring device 31, 32, 33, 34, 35, 36 are of the same structure and are respectively arranged at different positions on the first platform 1. Figure 5-6 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 disposed 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 disposed on the sliding rail base, a roller 2314, 2414 rotatably disposed on the sliding base, and a pneumatic cylinder 2315, 2415 driving the sliding base 2313, 2413 along the sliding rail 2312, 2412 of the sliding rail base 2311, 2411 to approach or move away from the floor unit 101. With this structure, when the clamping mechanism 2 pushes the floor unit 101, the friction damage around 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 have: 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 disposed on the slide rail of the side length base; 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 Figure 7 to Figure 9 As shown, a four-legged height measuring device 41 may be provided on the first platform 1 . Figure 8 for Figure 7, wherein the front clamping structure is omitted, which is the same as the clamping mechanism 2 for convenience of illustration. When measuring the four-leg height, after the four sides are measured, the first to sixth side length measuring devices 31, 32, 33, 34, 35, 36 can be reset respectively. At this time, the clamping mechanism 2 still positions and fixes the floor unit 101 to continue to measure the four-leg height at the same station. The four-leg height measuring device 41 is suspended above the four corners of the floor unit 101 to measure the leg height H1 of the four corners of the floor unit 101 to obtain the four-leg height measurement value. Furthermore, in order to facilitate the measurement and replacement of the floor unit 101, the first platform 1 may be further provided with: four cantilever support seats 42, which are provided on the first platform 1 and are 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 being rotatably provided on the four cantilever support seats 42, so that the suspension ends 432 of the four cantilevers 43 can swing between the four corners of the floor unit 101 and the outside of the floor unit 101; four swinging pneumatic cylinders 44, which respectively drive the four cantilevers 43 to swing; and a four-leg height measuring device 41 provided at the suspension ends 432 of the four cantilevers 43. In addition, the four-leg height measuring device 41 may use a laser rangefinder 413 or a displacement meter (not shown) as a measuring device, and the laser rangefinder 413 is taken as an example for explanation as follows. The four-legged height measuring device 41 has a pneumatic cylinder 411 , a fixing base 412 and a laser distance meter 413 .

[0040] The pneumatic cylinder 411 comprises: a cylinder body 4111 fixed on the suspension end 432 of the cantilever, having a pneumatic chamber 41111 inside thereof, 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 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 of the cylinder body 4111, the air pressure chamber 41111 and the lower through hole 41113. 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 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 seat 412 is fixed on the top of the pneumatic cylinder 411 and has a containing space 4121 . The laser distance measuring piece 41122 is arranged in the containing space 4121 , so that the laser distance measuring piece 41122 can move up and down in the containing space 4121 of the fixing seat 412 .

[0042] The laser distance meter 413 is disposed at the top of the accommodating space 4121 of the fixing seat 412 , and can measure the distance H2 between the laser distance meter 41122 and the laser distance meter sheet 41122 .

[0043] Before using the foot height measuring device 41 for measurement, a sample plate that meets the standard size is first taken for zeroing. That is, after positioning the sample plate with the clamping mechanism 2, the pneumatic cylinder 411 is started so that the floor fixing plate 41123 presses the sample plate downward. At this time, the laser rangefinder 413 is used to measure the distance between the laser rangefinder 413 and the laser rangefinder plate 41122 to be zero, which is the zeroing operation. Then, after replacing the floor unit 101 to be tested, the distance between the laser rangefinder 413 and the laser (laser) rangefinder plate 41122 is measured again to determine whether the foot height of the floor unit 101 to be tested is qualified. Now, take the sample plate with a foot height of 60±0.1mm as an example to explain as follows. After completing the zeroing with the sample plate, remove the sample plate and replace it with the board to be tested. If the four foot height measurement values ​​obtained by measurement exceed ±0.1mm, the foot height is judged to be unqualified. On the contrary, if the four foot height measurement values ​​obtained by measurement are within ±0.1mm, the foot height is judged to be qualified. 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 floor unit under test 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 on the top surface, thereby ensuring the accuracy of the measured foot height value.

[0045] In addition, on the first platform 1, a corner gasket 12 can be respectively provided corresponding to the positions of the four corners of the groove floor unit 101, so that the positions of the four corners of the floor unit 101 are all located on the same horizontal plane of the platform when measuring the floor. The corner gasket 12 can adopt a variety of different groove floor units 101 to adapt to floor units of different heights. In addition, the top surface 121 of the corner gasket 12 can be a smooth surface to avoid the wear of the bottom of the floor unit 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 need not be used.

[0046] like Fig.10As shown, in order to save manpower, the utility model can further have: a second platform 5, arranged in front of the first platform 1; a third platform 6, arranged behind the first platform 1; a transport mechanism 7, the transport mechanism 7 further includes: a support frame 71, a transport track 72 is set above the first platform 1, the second platform 5 and the third platform 6; at least one grabbing mechanism 73, arranged on the transport track 72, can move along the transport track 72, and can grab and transport the floor unit 101 between the first platform 1, the second platform 5 and the third platform 6. In this embodiment, two grabbing mechanisms 73 are used. When the first grabbing mechanism 73 transports the measured floor unit to the third platform 6, the second grabbing mechanism 73 can simultaneously transport the floor unit to be tested on the second platform 5 to the first platform 1, which can not only reduce the standby time of the measuring equipment to increase the overall work efficiency, but also facilitate automated operations.

[0047] The above embodiments of the present invention are only provided for the convenience of explanation and should not be used to limit the significance 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.
