Description

Technical Field

[0001] This utility model relates to an automated four-leg height measuring device for raised floors; in particular, it relates to an automated four-leg height measuring device for raised floors that can measure the height of the four legs of the raised floor when the raised floor surface is facing down and the raised floor is pressed flat. Background 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 both time-consuming and costly.

[0003] To address the aforementioned issues, the designers of this case disclosed various measuring devices for raised floors in Taiwanese patents TWI875568, TWI875567, and TWI875566. 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 some of the raised floor's bottom to warp, leading to errors in measuring foot height. Furthermore, the surface material of the raised floor may be too soft, indicating room for improvement.

[0004] In view of this, the designer of this case pondered deeply, actively researched, and combined with many years of experience in related product research, and through continuous experimentation and improvement, finally developed this utility model. Utility Model Content

Detailed Implementation

[0037] like Figures 1 to 17As shown, this utility model provides an automated four-leg height measuring device 100 for raised floors, comprising: a first platform 1 on which a raised floor 101 is placed with its surface facing down and corner bottoms 1017 facing up; at least one pressing mechanism 8 disposed on the first platform 1 and located outside the raised floor 101, capable of pressing the raised floor 101 flat; and four leg height measuring devices 41 disposed above the four corners of the first platform 1, capable of measuring the four leg heights of the raised floor 101. With this structure, the four leg heights of the raised floor can be measured while the raised floor is pressed flat. A detailed description follows.

[0038] This utility model can be used to measure various types of raised floors, such as 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 (hereinafter referred to as blind panels) and other types of raised floors 101. This utility model takes a standard part with a size of 600×600×60mm as an example.

[0039] Raised floor 101 can be composed of a floor body 1015 and a surface material 1016 (e.g.) Figure 9 (As shown). The floor body 1015 can be made of materials such as aluminum alloy, while the surface material 1016 can be made of various materials. Furthermore, some surface materials 1016 have high elasticity. In this case, if the surface material 1016 of the raised floor 101 is placed on the first platform with the raised floor 101 facing upwards, the surface material 1016 may deform due to the downward pressure of, for example, the floor fixing piece 41123 or the pressure head 843, thus affecting the accuracy of the foot height measurement. Therefore, this invention places the raised floor 101 on the first platform 1 with the surface material 1016 facing downwards and the corner bottom 1017 facing upwards, in order to accurately measure the foot height of the raised floor 101.

[0040] The first platform 1 can be a steel frame structure. Figure 2 and Figures 5-7 The image is simply illustrated with a flat panel.

[0041] For ease of explanation, the raised floor 101 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, respectively.

[0042] The automated four-leg height 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 pressing mechanism 8, the leg height measuring device 41, and other components.

[0043] like Figures 1-2 and Figure 7As shown, 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 used as an example. The two pressing mechanisms 8 are respectively set on the first platform 1 and located outside the two opposite sides of the raised floor 101 (e.g., the left edge 1012, the right edge 1014, or the front edge 1011, the rear edge 1013). 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.

[0044] like Figures 2-7 As shown, 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.

[0045] 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.

[0046] 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 (e.g., Figures 6-7 As shown), the second pneumatic cylinder 84 can easily press the raised floor 101.

[0047] The first pneumatic cylinder 83 is used to drive the sliding block 82 to slide.

[0048] 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.

[0049] like Figure 2 As shown, the pressing base 81 may include a first plate 811 and at least one first track 812. The first track 812 is disposed on the top of the first plate 811. In this embodiment, two first tracks 812 are provided as an example.

[0050] like Figures 3-4As shown, the pressing slide seat 82 may include a second plate 822 and at least one second track 823. This embodiment uses two second tracks 823 as an example. The second track 823 is located at the bottom of the second plate 822 and connects to the first track 812, thereby facilitating the sliding of the pressing slide seat 82 and the second pneumatic cylinder 84, allowing the second plate 822 of the pressing slide seat 82 to slide along the first track 812 towards the raised floor 101 (e.g., ...). Figure 6 (as shown) or return to the origin (as shown) Figure 5 (As shown). Furthermore, the second pneumatic cylinder 84 has a retracted state (as shown). Figure 6 (as shown) and an extended state (such as) Figure 7 As shown). Figure 6 As shown, 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 along with the second pneumatic cylinder 84 above the raised floor 101 along the X-axis. After measurement, the first pneumatic cylinder 83 then retracts the pressing sliding seat 82 along with the second pneumatic cylinder 84 away from above the raised floor 101 along the X-axis, facilitating the return of the pressing mechanism 8 to its original position (e.g., ...). Figure 7 As shown), this clears the space above the raised floor 101, facilitating the gripping mechanism 73 (as shown). Figure 16 (As shown) After grabbing the raised floor 101, it can leave from the Z-axis direction.

[0051] like Figure 2 As shown, 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.

[0052] like Figure 4 As shown, 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.

[0053] like Figures 2-4 As shown, 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 engage 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.

[0054] like Figure 2 As shown, 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 located on the two sides of the top of the first plate 811, and the two second tracks 823 may be respectively located 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.

[0055] like Figure 6 As shown, 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.

[0056] like Figures 8-9 As shown, four foot height measuring devices 41 are positioned above the four corners of the first platform 1 to measure the foot height H1 of the raised floor 101, thereby obtaining the foot height measurement values. Furthermore, to facilitate 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 sides 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 ends 431 of the four cantilever arms 43 being rotatably mounted on the four cantilever support seats 42, allowing the suspension ends 432 of the four cantilever arms 43 to swing between the four corners of the raised floor 101 and the outer sides of the raised floor 101; four swinging pneumatic cylinders 44, each driving the four cantilever arms 43 to swing; and four foot height measuring devices 41 positioned on the suspension ends 432 of the four cantilever arms 43, facilitating the measurement of the foot height at the four corners of the raised floor.

[0057] The four foot height measuring devices 41 can operate in conjunction with a foot height measuring method. The foot height measuring method can be a program code recorded in the controller, which obtains the foot height of the four corners of the raised floor based on the measurement values ​​of the four foot height measuring devices.

[0058] Before measurement, zero the system using a standard component, then measure the raised floor. Standard marble can be used as the standard component; its dimensions (length, width, and height) must match those of a standard raised floor. Figure 5 and Figure 10As shown, before measuring foot height, the four foot height measuring devices 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.

[0059] like Figure 2 and Figure 6 As shown, 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.

[0060] like Figure 2 and Figure 7 As shown, the second pneumatic cylinder 84 then pushes the pressure head 843 along the Z-axis to the top of the raised floor 101, thereby pressing the raised floor 101 flat.

[0061] like Figures 8-9 As shown, the four cantilever 43s mounted on the four cantilever support seats 42 are rotated so that the four foot height measuring devices 41 are located above the four corners of the raised floor 101, and then the four foot height measuring devices 41 are used to make measurements.

[0062] like Figure 5 and Figure 10 As shown, after the measurement is completed, the four foot height measuring devices 41 first return to the origin, and then the four cantilever arms 43 and the pressing mechanism 8 return to the origin.

[0063] like Figures 11-12 As shown, the four foot height measuring devices 41 can be laser rangefinders or displacement meters (not shown in the figure) as measuring devices. The following is an example using a laser rangefinder 413. Each of the four foot height measuring devices 41 can have a pneumatic cylinder 411, a fixed base 412, and a laser rangefinder 413.

[0064] 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 different thicknesses of the floor. 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 foot height measuring devices 41 drives the floor fixing plate 41123 to press down, the floor fixing plates 41123 of the four foot height measuring devices 41 press against the four corners of the raised floor 101 respectively.

[0065] 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.

[0066] The laser rangefinder 413 is a conventional technology, so its internal structure is not shown in the cross-sectional view. The laser rangefinder 413 is located at the top of the accommodating space 4121 of the mounting base 412 and can measure the distance H2 between it and the laser rangefinder plate 41122.

[0067] For example, consider a standard part with dimensions of 600×600×60mm. Before measurement, zero the sample using a standard part where all four legs are 60mm high, and then begin the measurement. In the zeroing process for measuring the leg height, the step of flattening the raised floor with a pressing mechanism can be omitted.

[0068] Additionally, during the zeroing process for measuring foot height, such as Figure 11 As shown, the floor fixing plate 41123 is in the zero position when it is not extended. (The last sentence appears to be incomplete and possibly refers to another part of the text.) Figure 12As shown, when the floor fixing piece 41123 extends to the raised floor 101, it can be at a relative zero position, which can be set as the leg height of the standard part, i.e., 60mm. This makes the four leg heights of the raised floor the measured values ​​of the four leg height measuring instruments 41. In this state, taking a tested raised floor as an example, after measurement, the measured values ​​of the four leg height measuring instruments 41 are all 60mm, so the four leg heights of the raised floor are all 60mm. In addition, a leg height judgment method can be used to determine whether the leg height of the tested raised floor is qualified within a tolerance range of, for example, 60±0.1mm.

[0069] By cooperating with the air pressure chamber 41111 of the cylinder 4111 and the baffle 41121 of the rod 4112, the vertical movement range of the rod 4112 and the floor fixing plate 41123 is limited. In addition to making it convenient to return the foot height measuring device 41 to the origin after the foot height measurement is completed, it can also be conveniently used to measure raised floors of different heights.

[0070] The following further explains the features of raised floors that facilitate measurement at different heights. For example... Figure 11 and Figure 13 As shown, when the baffle 41121 and the floor fixing plate 41123 are located at the top dead center, the distance between the floor fixing plate 41123 and the first platform 1 is the first gap H3. Figure 11 and Figure 14 As shown, when the baffle 41121 and the floor fixing plate 41123 are at the bottom dead center, the distance between the floor fixing plate 41123 and the first platform 1 is the second distance H4. The first distance H3 is the upper limit of the height of the raised floor being tested, and the second distance H4 is the lower limit of the height of the raised floor being tested. That is to say, the height of the raised floor being tested (i.e., the foot height H1 as described in this utility model, such as...) Figure 15 (As shown) It must be at least lower than the first spacing H3 and higher than the second spacing H4. The difference between the first spacing H3 and the second spacing H4 represents the permissible height range of the raised floor to be measured. Therefore, this invention can conveniently measure raised floors of different heights. Furthermore, it is possible to increase the length of the air chamber 41111 of the cylinder 4111, and increase the length of corresponding components such as the rod 4112 and the fixing base 412, thereby increasing the vertical movement range of the rod 4112 and the floor fixing plate 41123, and thus increasing the permissible height range of the raised floor to be measured.

[0071] As mentioned above, since this case considers that the surface material 1016 may have high elasticity, the raised floor 101 is placed on the first platform 1 with the surface material 1016 facing down. Therefore, the raised floor 101 can be placed directly on the first platform 1 without using, for example, conventional corner pads (corner pads are not shown in the figure), so as to avoid the situation where pressure concentration causes deformation of the surface material and thus affects the measurement accuracy.

[0072] like Figures 16-17 As shown, to save manpower, this utility model 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; a transport mechanism 7, which further includes: a support frame 71, which supports 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, which can move along the transport track 72 and grip and transport the raised floor 101 between the first platform 1, the second platform 5, and the third platform 6. This embodiment takes the presence of two gripping mechanisms 73 as an example, and a connecting rod 731 is provided between the two gripping mechanisms 73 so that the two gripping mechanisms 73 can 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.

[0073] The above-described embodiments are for illustrative purposes only and should not be construed as limiting the scope of this utility model. All variations and designs made in accordance with this utility model should be included within the patent scope of this utility model.
