Description

Automated measuring devices for raised floors Technical Field

[0001] This invention relates to an automated measuring device for raised floors; more particularly to an automated measuring device for raised floors that can not only measure the four sides and squareness of the raised floor, but also measure the height of the four legs of the raised floor when the raised floor is pressed flat. Prior Technology

[0002] Raised floors are now widely used in computer rooms, clean rooms, and other similar spaces. A raised floor typically consists of at least four legs, at least four crossbeams, and at least one raised floor panel. It provides a highly flat surface above the ground, facilitates the installation of piping, and allows for easy control of cleanliness levels. Raised floors are a crucial structural element of the entire factory building. However, conventional methods for measuring raised floors mostly rely on manual measurement, which is not only time-consuming but also very costly.

[0003] To address the aforementioned issues, the inventors disclosed various measuring devices for raised floors in Republic of China patents I875568, I875567, and I875566. However, after heat treatment, raised floors may deform due to residual thermal stress, resulting in unevenness. Placing an uneven raised floor on the platform of the measuring device can cause the bottom of some sections of the raised floor to warp, thus introducing errors when measuring foot height.

[0004] In light of this, the creator pondered deeply, conducted extensive research, and, drawing upon years of experience in related product research, through continuous experimentation and improvement, finally developed this creation. Summary of the Invention

[0013] Preferably, the clamping mechanism has a front positioning structure and a left positioning structure to define a front reference line and a left reference line that are perpendicular to each other; the clamping mechanism also has a rear pushing mechanism and a right pushing mechanism to push the raised floor against the front positioning structure and the left positioning structure, wherein the front positioning structure is composed of two front fixed roller seats, the left positioning structure is composed of two left fixed roller seats; the rear pushing mechanism is composed of two rear sliding roller seats, and the right pushing mechanism is composed of a right sliding roller seat, which can facilitate clamping and fixing the raised floor.

[0014] Preferably, a standard component is first used on the first platform to simultaneously zero the measuring devices for the four sides, squareness, and four feet height of the raised floor. After the zeroing operation is completed, the standard component is removed, and the raised floor is picked up and placed on the first platform, while the four sides, squareness, and four feet height of the raised floor are measured simultaneously.

[0015] Preferably, a standard part is first zeroed out before measuring the raised floor. During measurement, the raised floor is first pushed by the right sliding roller seat so that the left edge overlaps with the left baseline. Then, the fifth and sixth side length measuring instruments are used for measurement. After that, the right sliding roller seat, the fifth side length measuring instrument, and the sixth side length measuring instrument return to the origin. Then, the two rear sliding roller seats are pushed by the raised floor so that the front edge overlaps with the front baseline. Then, the third and fourth side length measuring instruments are used for measurement. After that, the two rear sliding roller seats, the third side length measuring instrument, and the fourth side length measuring instrument return to the origin.

[0038] As shown in Figures 1-16, the automated measuring device 100 for raised floor of this invention includes: a first platform 1; a clamping mechanism 2, disposed on the first platform 1, clamping a raised floor 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; the first side length measuring device to the sixth side length measuring device 31, 32, 33, 34, 35, 36 are located on the same plane and arranged on the... The left, rear, and right sides of the raised floor 101 allow for the measurement of its four sides and squareness; at least one pressing mechanism 8, located on the first platform 1 and outside the raised floor 101, can press the raised floor 101 flat; four-leg height measuring devices 41, positioned above the four corners of the first platform 1, can measure the height of the four legs of the raised floor 101. This structure allows for the measurement of not only the four sides and squareness of the raised floor, but also the height of the four legs while the raised floor is pressed flat. This will be explained in detail below.

[0039] This invention can be used to measure, for example, honeycomb raised floors (not shown in the figure), grid raised floors (not shown in the figure), window raised floors (not shown in the figure), blind raised floors (abbreviated as blind panels, this invention takes blind panels as an example) and other types of raised floors 101.

[0040] The first platform 1 can be a steel frame structure, which is simply illustrated as a flat plate in Figures 2-4.

[0041] As shown in Figures 1 and 2, 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.

[0042] As shown in Figures 2-3, 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 raised floor 101 from the rear and right sides respectively, causing the front edge 1011 and left edge 1012 of the raised floor to rest against the two front fixed roller seats 211 and the two left fixed roller seats 221, thereby fixing the raised floor 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 raised floor 101 under test.

[0043] The front edge 1011 of the raised floor 101 overlaps with the front reference line, serving as the primary reference for measurement. Therefore, it is not necessary to install a side length measuring device on the front side. Measurements can be completed simply by installing the first to sixth side length measuring devices 31, 32, 33, 34, 35, and 36 on the left, rear, and right sides of the raised floor. For example, the first side length measuring device 31 measures the left edge of the raised floor near the front; the second side length measuring device 32 measures the left edge of the raised floor near the rear; the third side length measuring device 33 measures the rear edge of the raised floor near the left; the fourth side length measuring device 34 measures the rear edge of the raised floor near the right; the fifth side length measuring device 35 measures the right edge of the raised floor near the front; and the sixth side length measuring device 36 measures the right edge of the raised floor near the rear. In addition, for ease of explanation, the raised floor 101 clamped by the clamping mechanism 2 is used as a reference, and the length (front edge 1011), width (left edge 1012) and height of the raised floor 101 are defined as the X-axis, Y-axis and Z-axis directions.

[0044] The automated measuring device 100 for raised floors may further include a controller. The controller may be, for example, a computer or a programmable logic controller (PLC) (not shown in the figure), for controlling the clamping mechanism 2, the first side length measuring devices to the sixth side length measuring devices 31, 32, 33, 34, 35, 36 and other components.

[0045] The automated measuring device 100 for raised floors may also have a side length measuring means and a squareness measuring means, which can measure the side length and squareness of the raised floor through the clamping mechanism 2 in different clamping methods.

[0046] The side length measurement method can be a program code recorded in the controller, which obtains the lengths of the front edge 1011, left edge 1012, rear edge 1013 and right edge 1014 of the raised floor based on the measurement values ​​of the third to sixth side length measuring devices 33, 34, 35 and 36.

[0047] Before measurement, a standard piece is used for zeroing. Then, the raised floor is measured. This means that the measuring instruments for the four sides, squareness, and leg height of the raised floor are simultaneously zeroed on the first platform 1. After zeroing, the standard piece is removed, and the raised floor to be measured is picked up and placed on the first platform 1. The four sides, squareness, and leg height of the raised floor are then measured simultaneously. A standard marble slab can be used as the standard piece, with dimensions identical to the length, width, and height of a standard raised floor.

[0048] During measurement, firstly, the right-side sliding roller seat 241 pushes the raised floor 101 so that the left edge 1012 overlaps with the left baseline L12. Then, the fifth side length measuring device 35 and the sixth side length measuring device 36 are used for measurement. Afterward, the right-side sliding roller seat 241, the fifth side length measuring device 35, and the sixth side length measuring device 36 return to their original positions. Next, the two rear-side sliding roller seats 231 push the raised floor 101 so that the front edge 1011 overlaps with the front baseline L11. Then, the fifth side length measuring device 35 and the sixth side length measuring device 36 are used for measurement. The three-sided length measuring device 33 and the fourth-sided length measuring device 34 are used for measurement. Then, the two rear sliding roller seats 231, the third-sided length measuring device 33 and the fourth-sided length measuring device 34 are returned to the origin. The lengths of the front edge 1011, rear edge 1013, left edge 1012 and right edge 1014 of the raised floor 101 are the dimensions of the standard part minus the measured values ​​of the fifth-sided length measuring device 35, the sixth-sided length measuring device 36, the third-sided length measuring device 33 and the fourth-sided length measuring device 34.

[0049] For example, take a standard part with dimensions of 600x600x60mm. Before measurement, first zero the standard part with all four sides being 600mm, and then begin the measurement.

[0050] Taking a raised floor under test as an example, after measurement, the fifth side length measuring device 35 measured a value of 0, so the length of the front edge 1011 is 600-0=600mm. The sixth side length measuring device 36 measured a value of -0.05, so the length of the rear edge 1013 is 600-(-0.05)=600.05mm. The third side length measuring device 33 measured a value of 0, so the length of the left edge 1012 is 600-0=600mm. The fourth side length measuring device 34 measured a value of 0.05, so the length of the right edge 1014 is 600-0.05=599.95mm.

[0051] In addition, the side length of the tested standard part can be determined to be within a tolerance range of, for example, 600x600±0.1mm by using a side length determination method.

[0052] The squareness measurement method can be a program code recorded in the controller, which obtains the squareness of the left edge 1012, rear edge 1013 and right edge 1014 of the raised floor 101 based on the measurement values ​​of the first side length measuring device to the sixth side length measuring device 31, 32, 33, 34, 35 and 36.

[0053] Before measurement, a standard part is used to perform zeroing operations, and then the raised floor is measured.

[0054] During measurement, the two rear sliding roller seats 231 are first used to push the raised floor 101 so that the front edge 1011 overlaps with the front reference line L11. Then, the right sliding roller seat 241 is used to make at least one point on the left edge 1012 overlap with the left reference line L12. Then, the first to sixth side length measuring instruments 31, 32, 33, 34, 35, and 36 are used for measurement. Then, the two rear sliding roller seats 231, the right sliding roller seat 241, and the sixth side length measuring instruments 35 and 36 are used for measurement. The length measuring devices 31, 32, 33, 34, 35, and 36 of the first side length measuring device return to their original positions. The squareness of the left edge 1012, rear edge 1013, and right edge 1014 of the raised floor 101 are respectively the measured value of the first side length measuring device 31 minus the measured value of the second side length measuring device 32, the measured value of the third side length measuring device 33 minus the measured value of the fourth side length measuring device 34, and the measured value of the fifth side length measuring device 35 minus the measured value of the sixth side length measuring device 36.

[0055] For example, take a standard part with dimensions of 600x600x60mm. Before measurement, first zero the standard part with four sides of 600mm, and then begin the measurement.

[0056] Taking a raised floor under test as an example, after measurement, the first side length measuring device 31 measured 0, the second side length measuring device 32 measured 0, so the squareness of the left edge 1012 is 0-0=0. The third side length measuring device 33 measured 0, the fourth side length measuring device 34 measured 0.05, so the squareness of the rear edge 1013 is 0-0.05=-0.05. The fifth side length measuring device 35 measured 0, the sixth side length measuring device 36 measured -0.05, so the squareness of the right edge 1014 is 0.05-(-0.05)=0.05.

[0057] In addition, a squareness determination method can be used to determine whether the squareness of the tested raised floor is up to standard.

[0058] After the four sides and squareness of the raised floor are measured, the clamping mechanism 2 and the first to sixth side length measuring devices 31, 32, 33, 34, 35, and 36 are all returned to their original positions so that the foot height of the raised floor can be measured later.

[0059] As shown in Figures 1-3 and Figure 9, before measuring the foot height, at least one pressing mechanism 8 is used to press the raised floor 101 from the Z-axis direction. In this embodiment, two pressing mechanisms 8 are provided as an example. The two pressing mechanisms 8 are respectively provided on the first platform 1 and located on the outside of the opposite two sides (e.g., left and right sides or front and rear sides) of the raised floor 101. The pressing head 843 of the pressing mechanism 8 can be moved to the top of the raised floor 101 and then moved downward to press the raised floor 101 flat.

[0060] As shown in Figures 4-9, the pressing mechanism 8 further includes a pressing base 81, a pressing sliding seat 82, a first pneumatic cylinder 83, and at least a second pneumatic cylinder 84.

[0061] The pressing base 81 is disposed on the first platform 1 and located on the outside of one side of the raised floor 101, and is used to guide the sliding direction of the pressing slide 82.

[0062] The pressing sliding seat 82 is slidably disposed on the pressing base 81; the pressing sliding seat 82 has a suspension part 821 at the position facing the raised floor 101, the suspension part 821 is used to support the second pneumatic cylinder 84; after the pressing sliding seat 82 slides towards the raised floor 101, the suspension part 821 is located above the raised floor 101 (as shown in Figures 8-9), which facilitates the second pneumatic cylinder 84 to press the raised floor 101.

[0063] The first pneumatic cylinder 83 is used to drive the sliding block 82 to slide.

[0064] The second pneumatic cylinder 84 has a cylinder body 841, a piston rod 842, and a pressure head 843 disposed at the end of the piston rod 842 of the second pneumatic cylinder 84; the cylinder body 841 of the second pneumatic cylinder 84 is disposed on the suspension part 821 of the pressing sliding seat 82; when the suspension part 821 of the pressing sliding seat 82 is placed above the raised floor 101, the piston rod 842 of the second pneumatic cylinder 84 can slide downward to make the pressure head 843 press the raised floor 101.

[0065] As shown in Figure 4, the pressing base 81 may include a first plate 811 and at least one first track 812. The first track 812 is located on the top of the first plate 811. In this embodiment, two first tracks 812 are provided as an example.

[0066] As shown in Figure 6, the pressing slide seat 82 may include a second plate 822 and at least one second track 823. In this embodiment, two second tracks 823 are provided as an example. The second track 823 is located at the bottom of the second plate 822 and is connected to the first track 812, thereby facilitating the sliding of the pressing slide seat 82 and the second pneumatic cylinder 84, so that the second plate 822 of the pressing slide seat 82 can slide along the first track 812 toward the raised floor 101 (as shown in Figure 8) or return to the origin (as shown in Figure 7). In addition, the second pneumatic cylinder 84 has a retracted state (as shown in Figure 8) and an extended state (as shown in Figure 9). As shown in Figure 8, when the second pneumatic cylinder 84 is in the retracted state, the bottom 8431 of the pressure head 843 of the second pneumatic cylinder 84 is higher than the top of the raised floor 101. With this structure, before measurement, the first pneumatic cylinder 83 pushes the pressing sliding seat 82 together with the second pneumatic cylinder 84 along the X-axis to above the raised floor 101. After measurement, the first pneumatic cylinder 83 then moves the pressing sliding seat 82 together with the second pneumatic cylinder 84 back along the X-axis away from above the raised floor 101, which makes it easy to return the pressing mechanism 8 to its origin (as shown in Figure 7), thereby clearing the space above the raised floor 101, so that the gripping mechanism 73 (as shown in Figure 13) can grip the raised floor 101 and leave from the Z-axis.

[0067] As shown in Figure 4, the first track 812 may include: a track body 8121, located on the top of the first plate 811; and two upper wing plates 8122, located on the upper sections of the two sides of the track body 8121.

[0068] As shown in Figure 6, the second track 823 may include: a top plate 8231, disposed at the bottom of the second plate 822; two side plates 8232, disposed on the two sides of the bottom of the top plate 8231; and two inner flanges 8233, extending inward from the bottom of the opposite inner side of the two side plates 8232 for a predetermined length, with an opening between the two side plates 8232 larger than the track body 8121.

[0069] As shown in Figures 3-6, the two side plates 8232 of the second track 823 cover the two upper flanges 8122 of the first track 812, and the two inner flanges 8233 are engaged with the bottom of the two upper flanges 8122. With this structure, the cooperation between the first track 812 and the second track 823 can not only guide the pressing sliding seat 82, but also withstand upward and downward pressure, so as to serve as a support base when the pressure head 843 of the second pneumatic cylinder 84 presses the raised floor 101.

[0070] As shown in Figure 4, the first pneumatic cylinder 83 has a cylinder body 831 and a piston rod 832. The cylinder body 831 of the first pneumatic cylinder 83 is located at the top of the first plate 811, and the piston rod 832 of the first pneumatic cylinder 83 is connected to the bottom of the second plate 822. A connecting member 8321 may be provided on the piston rod 832, and the second plate 822 is locked to the connecting member 8321 with at least one screw (not shown in the figure). In addition, as mentioned above, this embodiment may provide two first tracks 812 and two second tracks 823. The two first tracks 812 may be respectively provided on the two sides of the top of the first plate 811, and the two second tracks 823 may be respectively provided on the two sides of the bottom of the second plate 822. The cylinder body 831 is located in the middle section of the top of the first plate 811, thereby increasing the stability of the sliding seat 82 when it slides.

[0071] As shown in Figure 8, when the second pneumatic cylinder 84 is in the retracted state, the bottom 8431 of the pressure head 843 of the second pneumatic cylinder 84 is higher than the top of the raised floor 101. In order to ensure the height of the bottom 8431 of the pressure head 843 when the second pneumatic cylinder 84 is in the retracted state, several supports 813 may be provided at the bottom of related structures such as the pressing base 81 to increase the height.

[0072] As shown in Figures 10-11, the four-leg height measuring device 41 is positioned above the four corners of the first platform 1 to measure the four-leg height H1 of the raised floor 101, thereby obtaining the measured value of the four-leg height. Furthermore, to facilitate the measurement and replacement of the raised floor 101, the first platform 1 may be further provided with: four cantilever support seats 42, positioned on the first platform 1 and located on the outer side of the four corners of the raised floor 101; four cantilever arms 43, each having a pivot end 431 and a suspension end 432, the pivot end 431 of the four cantilever arms 43 being rotatably mounted on the four cantilever support seats 42, so that the suspension end 432 of the four cantilever arms 43 can swing between the four corners of the raised floor 101 and the outer side of the raised floor 101; four swinging pneumatic cylinders 44, each driving the four cantilever arms 43 to swing; and the four-leg height measuring device 41 is positioned at the suspension end 432 of the four cantilever arms 43, which facilitates the measurement of the leg height at the four corners of the raised floor.

[0073] The four-leg height measuring device 41 can operate in conjunction with a single-leg height measuring method. The leg height measuring method can be a program code recorded in the controller, which obtains the leg height of the four corners of the raised floor based on the measurement values ​​of the four-leg height measuring device.

[0074] After measuring the length and squareness of the four sides, the foot height can be measured. Before measurement, a standard part is used for zeroing, and then the raised floor is measured. As shown in Figures 7 and 12, before measuring the foot height, the four-leg height measuring device 41, the four cantilever arms 43 and the pressing mechanism 8 are located at the origin. The foot height measurement steps are explained in sections below.

[0075] As shown in Figures 3 and 8, the first pneumatic cylinder 83 first pushes the pressing sliding seat 82 together with the second pneumatic cylinder 84 along the X-axis direction to the top of the raised floor 101.

[0076] As shown in Figures 3 and 9, the second pneumatic cylinder 84 then pushes the pressure head 843 along the Z-axis to the top surface of the raised floor 101, thereby pressing the raised floor 101 flat.

[0077] As shown in Figures 10-11, rotate the four cantilever 43 on the four cantilever support 42 so that the four-leg height measuring device 41 is located above the four corners of the raised floor 101, and then use the four-leg height measuring device 41 to make a measurement.

[0078] As shown in Figures 7 and 12, after the measurement is completed, the four-legged height measuring device 41 first returns to the origin, and then the four cantilever 43 and the pressing mechanism 8 return to the origin.

[0079] As shown in Figures 13-14, the four-leg height measuring device 41 can also use a laser rangefinder or displacement meter (not shown in the figure) as the measuring device. The following is an example of the laser rangefinder 413. The four-leg height measuring device 41 can have a pneumatic cylinder 411, a fixed base 412 and a laser rangefinder 413.

[0080] The pneumatic cylinder 411 comprises: a cylinder body 4111 fixed to the suspension end 432 of the cantilever, having an internal pneumatic chamber 41111, and having 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; and a rod body 4112 inserted into the cylinder body. Between the upper through hole 41112, the air pressure chamber 41111, and the lower through hole 41113 of the cylinder body 4111, a baffle 41121 that will not detach from the air pressure chamber 41111 is provided in the middle section of the rod body 4112. When measuring the floor height, the rod body 4112 moves up and down in the air pressure chamber 41111 according to the floor thickness. A laser rangefinder 41122 is provided at the top of the rod body 4112, and a floor fixing plate 41123 is provided at the bottom of the rod body 4112. When the rod body 4112 of the four-legged height measuring device 41 drives the floor fixing plate 41123 to press down, the floor fixing plate 41123 of the four-legged height measuring device 41 presses against the four corners of the top surface 1018 of the raised floor 101.

[0081] The fixed base 412 is fixed to the top of the pneumatic cylinder 411 and has a receiving space 4121. The laser rangefinder 41122 is disposed in the receiving space 4121, so that the laser rangefinder 41122 can move up and down in the receiving space 4121 of the fixed base 412.

[0082] The laser rangefinder 413 is a conventional technology, therefore its internal structure is not shown in the cross-sectional view. The laser rangefinder 413 is located at the top of the housing space 4121 of the mounting base 412 and can measure the distance H2 between itself and the laser rangefinder plate 41122. After the four-legged height measuring device 41 is zeroed, this distance H2 becomes the standard height, used for comparison when the laser rangefinder 413 measures the height of the raised floor 101.

[0083] For example, consider a standard part with dimensions of 600x600x60mm. Before measurement, zero the standard part with all four legs 60mm high, and then begin the measurement. In the zeroing process for measuring the leg height, the step of flattening the raised floor using a pressing mechanism can be omitted.

[0084] Furthermore, during the zeroing process for measuring leg height, as shown in Figure 13, the zero position is when the floor fixing plate 41123 is not extended. As shown in Figure 14, when the floor fixing plate 41123 extends to the raised floor 101, it can be considered a relative zero position, which can be set as the leg height of the standard component, i.e., 60mm. This ensures that the leg heights of the four legs of the raised floor are measured by the leg height measuring device 41. In this state, taking a tested raised floor as an example, after measurement, the measured values ​​of the four leg height measuring devices 41 are all 60mm, therefore the leg heights of the raised floor are all 60mm. Additionally, a leg height judgment method can be used to determine whether the leg height of the tested raised floor is acceptable within a tolerance range of, for example, 60±0.1mm.

[0085] In summary, after zeroing out a standard component, we can begin measuring each raised floor individually, and for each raised floor to be measured, we need to measure the length of its four sides, its squareness, and its leg height in sequence.

[0086] Additionally, the raised floor 101 may consist of a floor body 1015 and a panel 1016. The floor body 1015 may be made of materials such as aluminum alloy. The raised floor 101 is placed on the first platform 1 with the panel 1016 facing upwards and the corner bottoms facing downwards. When the floor fixing piece 41123 is pressed down, it will press on the panel 1016 of the raised floor 101.

[0087] As shown in Figures 15-16, to save manpower, this 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 that holds a transport track 72 above the first platform 1, the second platform 5, and the third platform 6; and at least one gripping mechanism 73 located on the transport track 72, capable of moving along the transport track 72 and gripping and transporting the raised floor 101 between the first platform 1, the second platform 5, and the third platform 6. This embodiment uses two gripping mechanisms 73 as an example, and a connecting rod 731 is provided between the two gripping mechanisms 73, allowing the two gripping mechanisms 73 to move synchronously. Thus, when the first gripping mechanism 73 transports the measured raised floor to the third platform 6, the second gripping mechanism 73 simultaneously transports the raised floor to be tested on the second platform 5 to the first platform 1. This not only reduces the standby time of the measuring equipment and thus increases overall work efficiency, but also facilitates automated operation. In addition, the second platform 5 may be provided with several positioning blocks 51. In this embodiment, three positioning blocks 51 are provided as an example, which can facilitate the initial positioning of the raised floor 101 when it is placed on the second platform 5, thereby facilitating the gripping mechanism 73 to grip the raised floor 101.

[0088] The above are examples of embodiments provided in this work for illustrative purposes only and should not be construed as limiting the scope of this work. In other words, all variations and designs made in accordance with the scope of the listed patent applications should be included within the scope of this work.
