Detailed Implementation

[0025] like Figures 1 to 7As shown, this utility model provides a four-leg height measuring device 100 for a raised floor unit, comprising: a first platform 1; a four-leg height measuring device 41, disposed above the four corners of the first platform 1, for measuring the leg height of the four corners of the floor unit 101 to obtain the leg height measurement value; and a leg height measuring means for obtaining the leg height of the four corners of the floor unit based on the measurement result of the four-leg height measuring device. The following will describe this in detail.

[0026] This invention can be used to measure various floor units 101, such as honeycomb floor units (not shown), grid floor units (not shown), window floor units (not shown), blind floor units (hereinafter referred to as blind panels, this invention uses blind panels as an example), and others. The floor unit 101 can consist of a floor body 1015 and a surface material 1016. The floor body 1015 can be made of materials such as aluminum alloy; the floor unit 101 of this invention has a size of 60×60 cm as an example, while the surface material 1016 can be made of various materials. Some surface materials 1016 have high elasticity. In this case, if the surface material 1016 of the floor unit 101 is deformed due to the downward pressure of the floor fixing plate 41123 when measuring the height of the four legs, the floor unit 101 can be placed with the surface material 1016 facing down and the bottom corner 1017 facing up before measuring the height of the four legs. This will allow the downward pressure of the floor fixing plate 41123 to press on the bottom corner 1017 of the floor unit 101, thereby preventing the surface material 1016 from deforming and affecting the accuracy of the measurement of the height of the four legs.

[0027] The first platform 1 can be a steel frame structure. Figure 4 The image is simply illustrated with a flat panel.

[0028] The four-leg height measuring device 100 of the raised floor unit 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 four-leg height measuring device 41 and other components.

[0029] like Figures 3-6As shown, the four-leg height measuring device 41 is suspended above the four corners of the floor unit 101 to measure the leg height H1 at the four corners of the floor unit 101 to obtain the leg height measurement value. Furthermore, to facilitate the measurement and replacement of the floor unit 101, the first platform 1 may be further provided with: four cantilever support bases 42, which are provided on the first platform 1 and located on the outside of the four corners of the floor unit 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 provided on the four cantilever support bases 42, so that the suspension end 432 of the four cantilever arms 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 drive the four cantilever arms 43 to swing respectively; and the four-leg height measuring device 41 is provided on the suspension end 432 of the four cantilever arms 43. In addition, the four-leg height measuring device 41 can use a laser rangefinder 413 or a 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 has a pneumatic cylinder 411, a fixed base 412 and a laser rangefinder 413.

[0030] The pneumatic cylinder 411 comprises: a cylinder body 4111 fixed to the suspension end 432 of the cantilever, having a pneumatic chamber 41111 inside, 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. Between the upper through hole 41112, the air pressure chamber 41111 and the lower through hole 41113 of the rod 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.

[0031] The fixed base 412 is fixed on 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.

[0032] The laser rangefinder 413 is located on top of the accommodating space 4121 of the fixed base 412 and can measure the distance H2 between it and the laser rangefinder 41122.

[0033] The four-leg height measuring device 41 can operate in conjunction with the one-leg height measuring means. The leg height measuring means obtains the leg height of the four corners of the floor unit based on the measurement results of the four-leg height measuring device 41. The leg height measuring means can be program code recorded in the controller, which obtains the leg height of the four corners of the floor unit based on the measurement results of the four-leg height measuring device; according to this structure, the four-leg height measurement method of the raised floor unit of this utility model can further include the following steps S30) to S32).

[0034] S30) Rotate the four cantilever 43 mounted on the four cantilever support 42 respectively, so that the four-leg height measuring device 41 is located above the four corners of the floor unit 101 (e.g., Figure 5 (As shown).

[0035] S31) causes the floor fixing piece 41123 of the four-legged height measuring device 41 to press down on the floor unit 101 (e.g., Figure 6 (As shown).

[0036] (S32) The distance between the laser rangefinder 413 and the laser rangefinder plate 41122 is measured using the laser rangefinder 413 of the four-leg height measuring device 41 to obtain the height of the four corners of the floor unit 101; the floor fixing plate 41123 returns to the origin, and then the four cantilever 43 returns to the origin (e.g., Figure 1 (As shown).

[0037] As described in steps S30) to S32), before measuring the leg height, the four-leg height measuring device 41 is placed outside the placement position of the floor unit 101 to facilitate the placement of the floor unit 101; when measuring the leg height, the four-leg height measuring device 41 is placed above the four corners of the floor unit 101 to obtain the leg height of the floor unit; after measuring the leg height, the four-leg height measuring device is returned to its original position to facilitate the replacement of another floor unit.

[0038] This utility model may also include a foot height determination method, which may be a program code recorded in the controller, thereby determining whether the tested floor unit meets the tolerance range.

[0039] like Figure 7 As shown, a floor sensor 13 and / or an automatic floor barcode scanner 14 may also be provided on the first platform 1, facing the floor unit 101. The floor sensor 13 is used to activate the aforementioned method for measuring the four-leg height of the raised floor unit only when it senses that a floor unit 101 has been installed on the first platform 1. In addition, a floor code (not shown in the figure) for each floor unit 101 may be provided at a predetermined position on the floor unit 101, so as to facilitate the storage of measured information such as the four-sided length, squareness, and four-leg height together with the corresponding floor code for subsequent work.

[0040] When the floor unit 101 is placed with the surface material 1016 facing down and the corner bottom 1017 facing up, the surface material 1016 of the floor unit 101 can be placed directly on the first platform 1 (not shown in the figure). At this time, the contact area between the first platform 1 and the surface material 1016 is larger than the area of ​​the bottom of the floor fixing piece 41123, thus effectively distributing the pressure applied to the surface material 1016 and preventing deformation of the surface material 1016. In addition, as Figure 5 As shown, four corner pads 12 can be provided on the first platform 1. The four corner pads 12 correspond to the four corners of the floor unit 101. The area of ​​the top of the corner pad 12 can be larger than the area of ​​the bottom of the floor fixing piece 41123. In this case, when the floor unit 101 is placed with the surface material 1016 facing down and the corner bottom 1017 facing up, the four corners of the surface material 1016 are placed on the four corner pads 12, which can effectively distribute the pressure applied to the surface material 1016 and prevent the surface material 1016 from deforming.

[0041] The above description is merely a preferred embodiment of the present utility model and is provided for ease of explanation only. It should not be construed as limiting the significance of the present utility model. All variations and designs made based on the present utility model should be included within the patent scope of the present utility model.
