DETAILED DESCRIPTION

[0027] like Figures 1 to 9 As shown, the foot height 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, 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; the 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; four-foot height measuring devices 41 are 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, so that the four-foot heights of the measured floor unit 101 can be accurately known. The following will be described in detail.

[0028] The first platform 1 can be a steel frame structure. Figure 2 to Figure 7 It is simply illustrated with a flat plate.

[0029] 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.

[0030] 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.

[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 the 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. 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, and the tested floor unit 101 can be easily replaced.

[0032] 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 are respectively arranged at different positions on the first platform 1. Figure 5-6 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 disposed 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 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.

[0034] like Figure 2 and Figure 7 As shown, the four-leg height measuring device 41 is arranged 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, 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 arranged 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 are rotatably arranged 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 the four-leg height measuring device 41 is arranged at the suspension ends 432 of the four cantilevers 43. In addition, the four-leg height measuring device 41 can use a laser rangefinder 413 or a displacement meter (not shown) as a measuring device, and the laser rangefinder 413 is used as an example for the following description. The four-leg height measuring device 41 has a pneumatic cylinder 411, a fixing seat 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, having a pneumatic chamber 41111 inside thereof, and having an upper through hole 41112 connected to the center of the top of the pneumatic chamber 41111, a lower through hole 41113 connected to the center of the bottom of the pneumatic chamber 41111, an upper air valve 41114 connected to the top of the pneumatic chamber 41111, and a lower air valve 41115 connected to 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.

[0036] 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.

[0037] 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 it and the laser distance measuring piece 41122 .

[0038] Before using the foot height measuring device 41 for measurement, first take a sample plate that meets the standard size for zeroing. That is, after positioning the sample plate with the clamping mechanism 2, start the pneumatic cylinder 411 so that the floor fixing plate 41123 presses the sample plate downward. At this time, the laser (laser) distance meter 413 is used to measure the distance between the laser (laser) distance meter 413 and the laser (laser) distance meter plate 41122 to zero, which is the zeroing operation. Then, after replacing the floor unit 101 to be tested, measure the distance between the laser (laser) distance meter 413 and the laser (laser) distance meter plate 41122 to determine whether the foot height of the floor unit 101 to be tested is qualified. The following is an example of a sample plate with a foot height of 60±0.1mm. 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-foot height exceed ±0.1mm, the foot height is judged to be unqualified. On the contrary, if the measured values ​​of the four-foot height are within ±0.1mm, the foot height is judged to be qualified. Therefore, it is possible to accurately calculate whether the four-foot height of the floor unit 101 is qualified, and then quickly complete the measurement of whether the foot height of the tested floor unit is within the tolerance range.

[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 floor unit 101 is pressed down with the floor fixing plate 41123 and then the laser rangefinder plate 41122 is measured. This ensures 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, corresponding to the positions of the four corners of the groove floor unit 101, a corner gasket 12 can be respectively provided, so that when measuring the floor, the positions of the four corners of the floor unit 101 are all located on the same horizontal plane of the platform. 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 7 With the floor shown, the corner spacers 12 need not be used.

[0041] like Fig. 9 As 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.

[0042] The above-mentioned embodiments of the present invention are only for the purpose 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.
