The raised floor generally includes at least four legs, at least four cross beams and at least one floor unit, which has the functions of forming a high flatness plane above the ground, facilitating the arrangement of pipelines and the control of cleanliness level. The floor unit is one of the main structures of the entire factory building and is very important. However, the conventional floor unit measurement method mostly uses manual measurement, which is not only time-consuming but also very costly.

Detailed Implementation

[0035] like Figures 1-17 As shown, this utility model provides an improved measuring device 100 for a raised floor unit, comprising: a first platform 1; a clamping mechanism 2 disposed 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 mutually perpendicular front reference line L11 and a left reference line L12; a first side length measuring device to a sixth side length measuring device 31, 32, 33, 34, 35, 36, located on the same plane and arranged on the left, rear, and right sides of the floor unit 101; a side length measuring means and a squareness measuring means, which can respectively measure the side length and squareness of the floor unit through the clamping mechanism 2 in different clamping methods. This will be described in detail below.

[0036] This utility model can be used to measure, for example, honeycomb floor units (not shown in the figure), grid floor units (not shown in the figure), window floor units (not shown in the figure), blind floor units (hereinafter referred to as blind plates, this utility model takes blind plates as an example) and other types of floor units 101.

[0037] The first platform 1 can be a steel frame structure. Figures 2-9 and Figure 17 The image is simply illustrated with a flat panel.

[0038] like Figures 1-2 As shown, the front positioning structure 21 of the clamping mechanism 2 can be composed of two front fixed roller seats 211. The two front fixed roller seats 211 form the front reference line L11. In addition, the left positioning structure 22 can 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.

[0039] like Figure 3 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. These mechanisms can push the floor unit 101 from the rear and right sides respectively, causing the front edge 1011 and left edge 1012 of the floor unit to rest against the two front fixed roller seats 211 and the two left fixed roller seats 221, thereby fixing the floor unit 101 for measurement. After measurement, the rear pushing mechanism 23 and the right pushing mechanism 24 can be returned to their original positions for easy replacement of the floor unit 101 under test.

[0040] like Figures 3-5 As shown, the two front fixed roller seats 211 and the two left fixed roller seats 221 have the same structure. Taking the front fixed roller seat 211 as an example, it can be composed of a base 2111 and a roller 2112 rotatably mounted on the base.

[0041] The rear sliding roller seat 231 and the right sliding roller seat 241 have the same structure. Taking the right sliding roller seat 241 as an example, it can be composed of a slide rail base 2411 with a slide rail 2412 on the top, a sliding base 2413 slidably mounted on the slide rail base, a roller 2414 rotatably mounted on the sliding base, and a pneumatic cylinder 2415 that drives the sliding base 2413 to move closer to or away from the floor unit 101 along the slide rail 2412 of the slide rail base 2411. With this structure, friction damage to the perimeter of the floor unit 101 can be avoided when the clamping mechanism 2 pushes the floor unit 101.

[0042] The first to sixth edge length measuring devices 31, 32, 33, 34, 35, 36 are of the same structure. Taking the fifth edge length measuring device 35 as an example, each of the first to sixth edge length measuring devices 31, 32, 33, 34, 35, 36 can have an edge length base 351 fixed on the first platform 1, an edge length displacement meter 353 slidably arranged on a slide rail 352 of the edge length base 351, and an edge length pneumatic cylinder 354 for driving the edge length displacement meter to move towards or away from the floor unit along the slide rail.

[0043] The front side edge 1011 of the floor unit 101 overlaps with the front reference line and serves as the main reference for measurement, so no edge length measuring device is needed to be arranged on the front side. The first to sixth edge length measuring devices 31, 32, 33, 34, 35, 36 can be arranged on the left side, the rear side and the right side of the floor unit to complete the measurement. For example, the first edge length measuring device 31 measures the position of the left side edge of the floor unit close to the front side, the second edge length measuring device 32 measures the position of the left side edge of the floor unit close to the rear side, the third edge length measuring device 33 measures the position of the rear side edge of the floor unit close to the left side, the fourth edge length measuring device 34 measures the position of the rear side edge of the floor unit close to the right side, the fifth edge length measuring device 35 measures the position of the right side edge of the floor unit close to the front side, and the sixth edge length measuring device 36 measures the position of the right side edge of the floor unit close to the rear side.

[0044] The improved measurement device 100 for the floor unit of the raised floor can further have a controller. The controller can be, for example, a computer or a programmable logic controller (PLC) (not shown in the figure) for controlling the clamping mechanism 2, the first to sixth edge length measuring devices 31, 32, 33, 34, 35, 36 and other components.

[0045] The edge length measuring means can be a program code recorded in the controller, which obtains the lengths of the front side edge 1011, the left side edge 1012, the rear side edge 1013 and the right side edge 1014 of the floor unit according to the measurement results of the third to sixth edge length measuring devices 33, 34, 35, 36. According to this structure, the present application further discloses an improved measurement method for the floor unit of the raised floor. The improved measurement method for the floor unit of the raised floor of the present application at least includes the following steps S10) to S15).

[0046] The present application can be used to measure floor units of various sizes by clamping the floor unit 101 by the clamping mechanism 2, so that a sample plate of a standard size can be used to perform zero setting when measuring floor units of the same size.

[0047] S10) The front side edge 1011 of the floor unit 101 is overlapped with a front reference line L11 by the clamping mechanism 2. Step S10) can push the floor unit 101 by the two rear side sliding roller seats 231 so that the front side edge 1011 of the floor unit 101 leans against the two front side fixed roller seats 211, and then the front side edge 1011 is overlapped with the front reference line L11.

[0048] S11) The position of the rear side edge 1013 of the floor unit 101 close to the left side is measured by a third edge length measurer 33 to obtain a first edge length measurement information, and the position of the rear side edge 1013 of the floor unit 101 close to the right side is measured by a fourth edge length measurer 34 to obtain a second edge length measurement information. As shown in Figure 6 , step S11) can drive the edge length displacement meter close to the floor unit by the edge length pneumatic cylinders of the third to fourth edge length measurers 33, 34, so as to complete the measurement.

[0049] S12) The length of the left side edge 1012 of the floor unit is obtained according to the first edge length measurement information and the front reference line, and the length of the right side edge 1014 of the floor unit is obtained according to the second edge length measurement information and the front reference line; the clamping mechanism 2, the third edge length measurer 33 and the fourth edge length measurer 34 return to the original position (as shown in Figure 3 ).

[0050] S13) The left side edge 1012 of the floor unit 101 is overlapped with a left reference line L12 by the clamping mechanism 2. Step S13) can push the floor unit 101 by the right side sliding roller seat 241 so that the left side edge 1012 of the floor unit 101 leans against the two left side fixed roller seats 221, and then the left side edge 1012 is overlapped with the left reference line L12.

[0051] S14) The position of the right side edge 1014 of the floor unit close to the front side is measured by a fifth edge length measurer 35 to obtain a third edge length measurement information, and the position of the right side edge 1014 of the floor unit close to the rear side is measured by a sixth edge length measurer 36 to obtain a fourth edge length measurement information. As shown in Figure 7 , step S14) can drive the edge length displacement meter close to the floor unit by the edge length pneumatic cylinders of the fifth to sixth edge length measurers 35, 36, so as to complete the measurement.

[0052] S15) The length of the front side edge 1011 of the floor unit is obtained according to the third edge length measurement information and the left reference line, and the length of the rear side edge 1013 of the floor unit is obtained according to the fourth edge length measurement information and the left reference line; the clamping mechanism 2, the fifth edge length measurer 35 and the sixth edge length measurer 36 return to the original position (as shown in Figure 3 ).

[0053] As described in steps S10) to S15), when measuring the length of the front side edge 1011 and the rear side edge 1013 of the floor unit 101, the left side edge 1012 and the left reference line L12 are used as the basis, and when measuring the length of the left side edge 1011 and the right side edge 1013 of the floor unit 101, the front side edge 1011 and the front reference line L11 are used as the basis, which can reduce the error caused by possible poor squareness, and further obtain more accurate edge length of the floor unit 101. Further, when measuring the edge length, first push the floor unit to the front side fixed roller seat 211 by the two rear side sliding roller seats 231, so that the front side edge 1011 overlaps the front reference line L11, and then subtract the measurement information obtained by the third edge length measurer 33 and the fourth edge length measurer 34 to obtain the error data of the edge length. Then, make the rear side sliding roller seat 231, the third edge length measurer 33 and the fourth edge length measurer 34 return to the original position, and then push the floor unit to the left side fixed roller seat 221 by the right side sliding roller seat 241, so that the left side edge 1012 overlaps the left reference line L12, and then subtract the measurement information obtained by the fifth edge length measurer 35 and the sixth edge length measurer 36 to obtain the error data of the edge length. Then, make the right side sliding roller seat 241, the fifth edge length measurer 35 and the sixth edge length measurer 36 return to the original position, so as to facilitate subsequent measurement. For example, taking a floor unit with a standard size of 600*600mm as an example. Before measurement, first perform zero setting operation on a sample board with four edge lengths of 600*600mm, and then start measurement. Taking a measured floor unit as an example, if the measurement information obtained by the third edge length measurer 33 and the fourth edge length measurer 34 is 0.05, -0.05 and 0.05-(-0.05)=0.1mm respectively, then the side length of the measured floor unit is 600-0.1=599.9mm. The same edge length determination means can determine whether the edge length of the measured floor unit is qualified within a tolerance range of, for example, 600*600±0.1mm, and both sides need to be qualified.

[0054] The utility model discloses can ensure the delivery quality of floor unit, so before measurement, suppose that the measured floor unit is not necessarily square, so there is the left side edge 1012 of measured floor unit 101 not necessarily with front side edge 1011 vertical situation. If the left side edge 1012 of measured floor unit 101 is vertical with front side edge 1011, then the front side edge 1011 and left side edge 1012 of measured floor unit 101 will overlap with front reference line L11 and left reference line L12 respectively. Therefore, the clamping mechanism 2 is designed to overlap at least one point on the left side edge 1012 of the floor unit 101 with the left reference line L12 when positioning the floor unit with the clamping mechanism 2, thereby facilitating the measurement of the squareness of the floor unit.

[0055] The squareness measuring means can be program code recorded in the controller, which obtains the squareness of the left side edge 1012, the rear side edge 1013 and the right side edge 1014 of the floor unit 101 according to the measurement results of the first to sixth edge length measuring devices 31, 32, 33, 34, 35, 36. In this way, the improved measurement method of the floor unit of the raised floor can further include the following steps S20) to S22).

[0056] S20) The floor unit is first pushed to the front fixed roller seat 211 by the two rear side sliding roller seats 231, so that the front side edge 1011 overlaps the front reference line L11, and then the floor unit is pushed to the left fixed roller seat 221 by the right side sliding roller seat 241, so that at least one point on the left side edge 1012 overlaps the left reference line L12 (as shown in Figure 8 ).

[0057] S21) The first squareness measuring device 31 is used to measure the position of the left side edge of the floor unit close to the front side to obtain a first squareness measurement information, the second squareness measuring device 32 is used to measure the position of the left side edge of the floor unit close to the rear side to obtain a second squareness measurement information, the third squareness measuring device 33 is used to measure the position of the rear side edge of the floor unit close to the left side to obtain a third squareness measurement information, the fourth squareness measuring device 34 is used to measure the position of the rear side edge of the floor unit close to the right side to obtain a fourth squareness measurement information, the fifth squareness measuring device 35 is used to measure the position of the right side edge of the floor unit close to the front side to obtain a fifth squareness measurement information, and the sixth squareness measuring device 36 is used to measure the position of the right side edge of the floor unit close to the rear side to obtain a sixth squareness measurement information (as shown in Figure 9 ).

[0058] S22) The squareness measuring means obtains the squareness of the left side edge 1012 of the floor unit according to the first squareness measurement information, the second squareness measurement information and the front reference line, obtains the squareness of the rear side edge 1013 of the floor unit according to the third squareness measurement information, the fourth squareness measurement information and the front reference line, and obtains the squareness of the right side edge 1014 of the floor unit according to the fifth squareness measurement information, the sixth squareness measurement information and the front reference line; the clamping mechanism 2 and the first to sixth edge length measuring devices 31, 32, 33, 34, 35, 36 return to the original position (as shown in Figure 3 ).

[0059] As described in steps S20) to S22), when measuring the squareness of the floor unit 101, the squareness of the left side edge 1012, the back side edge 1013 and the right side edge 1014 of the floor unit 101 relative to the right side edge, the front side edge and the left side edge can be obtained based on the front side edge 1011 and the front reference line L11 and the left side edge 1012 and the left reference line L12, and then the measured floor unit can be accurately determined whether it is qualified. Further, before measuring the squareness, the standard block (the standard block can be a 60x60cm floor unit) is first pushed to the front fixed roller seat 211 by the two back side sliding roller seats 231 so that the front side edge 1011 overlaps the front reference line L11, and then the standard block is pushed to the left fixed roller seat 221 by a right side sliding roller seat 241 so that the left side edge 1012 overlaps the left reference line L12 (the standard block is a square, so its left side edge can overlap the left reference line. Conversely, the subsequent measured floor unit is not necessarily square, so only at least one point on the left side edge of the floor unit is overlapped with the left reference line when positioning), the first to sixth edge length measuring devices are zeroed, and then the back side sliding roller seat 231, the right side sliding roller seat 241 and the first to sixth edge length measuring devices 31, 32, 33, 34, 35, 36 are returned to the original position, so as to facilitate subsequent measurement of the squareness of the floor unit. Then, the squareness of the left side edge corresponding to the right side edge can be obtained by subtracting the second edge length measuring device 32 from the first edge length measuring device 31, the squareness of the back side edge corresponding to the front side edge can be obtained by subtracting the fourth edge length measuring device 34 from the third edge length measuring device 33, and the squareness of the right side edge corresponding to the left side edge can be obtained by subtracting the sixth edge length measuring device 36 from the fifth edge length measuring device 35. Then, the utility model can further have a squareness determination means, which can determine whether the squareness of the measured floor unit is qualified, and the left side edge, the back side edge and the right side edge all need to be qualified.

[0060] Figure 10 The second platform and the four-foot height measuring device of the utility model are shown in the schematic view, and the reinforcing ribs in the bottom frame of the floor unit are omitted for convenience. Figure 10 Figures 10-11 ​As shown, the utility model also can have a second platform 10; The second platform 10 is arranged in the first platform 1 side, and four high measuring devices 41 can be set on the second platform 10. In this case, after the floor unit 101 is measured on the first platform 1, the floor unit 101 can be placed on the second platform 10, to measure the four high of floor unit. In addition, the floor unit 101 can be composed of a floor body 1015 and a surface material 1016. Floor body 1015 can be made of materials such as aluminum alloy, and surface material 1016 can be made of various materials. Because some surface materials 1016 will have higher elasticity, the floor unit 101 can be placed on the second platform 10 with the surface material 1016 facing down and the corner bottom 1017 facing up, to prevent the surface material 1016 from deforming and affecting the accuracy of measuring the four high.

The foot height measuring structure can be program code recorded in the controller, which obtains the foot heights of the four corners of the floor unit according to the measurement results of the four-foot height measuring device 41. According to this structure, the improved measurement method of the floor unit of the raised floor of the utility model can further include the following steps S30) to S32).

[0066] S30) first place the floor unit with the surface material facing down and the corner bottom facing up, respectively rotate the four cantilevers 43 arranged on the four cantilever support seats 42, so that the four-foot height measuring device 41 is located above the four corners of the floor unit 101 (as shown in Figure 14

[0067] S31) make the floor fixing sheet 41123 of the four-foot height measuring device 41 press down the floor unit 101 (as shown in Figure 15

[0068] ​​S32) The distance between the laser range finder 413 and the laser range sheet 41122 is measured by the laser range finder 413 of the four-foot height measurer 41, and the height of the four corners of the floor unit 101 is obtained; the floor fixing sheet 41123 is returned to the original position, and then the four cantilever arms 43 are returned to the original position (as shown in Figure 10

[0069] As described in steps S30) to S32), before measuring the foot height, the four-foot height measurer 41 is placed outside the placement position of the floor unit 101, which facilitates the placement of the floor unit 101; when measuring the foot height, the four-foot height measurer 41 is placed above the four corners of the floor unit 101, so as to obtain the four-foot height of the floor unit; after measuring the foot height, the four-foot height measurer is returned to the original position, which facilitates the replacement of another floor unit.

In this embodiment, two grabbing mechanisms 73 are used, which can carry the measured floor unit to the second platform 10 by the first grabbing mechanism 73 while carrying the floor unit to be tested on the third platform 5 to the first platform 1 by the second grabbing mechanism 73 at the same time. This not only reduces the standby time of the measuring equipment and thus increases the overall work efficiency, but also facilitates automated operation.

[0072] As shown in Figure 17 ​As shown, a floor sensor 13 and / or a floor automatic scanning machine 14 can also be provided on the first platform 1 and face the floor units 101. The floor sensor 13 is used to start the improved measurement method of the raised floor floor unit when it senses that the first platform 1 has been provided with the floor units 101. In addition, a floor code (not shown in the figure) can be provided on the predetermined position of the floor unit 101 for each floor unit 101, so that the information such as the length, squareness and height of the four feet obtained by the measurement can be stored together with the corresponding floor code, and the subsequent work is facilitated.
