Description

Technical Field

[0001] This utility model relates to a measuring device and a lifting mechanism, and in particular to a lifting mechanism and a device for measuring the flatness of a raised floor. Background Technology

[0002] Raised floor is a flooring system widely used in semiconductor factories, offices, computer rooms, and other similar locations. It essentially consists of a supporting frame and multiple height-adjustable floor panels. These panels are raised above the ground, creating a space for the installation of electrical wires, cables, pipes, and other wiring, while also improving airflow and providing heat dissipation.

[0003] To ensure the flatness of the entire raised floor surface, it is necessary to check the flatness of the raised floor to avoid errors or structural problems after assembly. Methods for measuring the flatness of raised floors typically involve visually inspecting the horizontal line, requiring comparison at two or more points. Alternatively, a ruler or measuring rod can be used. The ruler is placed on the raised floor at different locations to check if it touches the ground; any unevenness indicates a problem with flatness. However, these methods are often labor-intensive, rely heavily on the experience and judgment of on-site engineers, and reduce overall project efficiency. Utility Model Content

[0055] Figure 1 This is a three-dimensional schematic diagram of the flatness measuring device for raised floors according to the present invention. Figure 2 This is a perspective view of an embodiment of the raised floor according to the present invention. Figure 3 This is a partial perspective view of the raised floor flatness measuring device according to the present invention, wherein... Figure 3 Measuring device 52 is omitted to show positioning device 53 and lifting device 54 of raised floor; please refer to [link to relevant documentation]. Figures 1 to 3 The raised floor flatness measuring device 50 of this utility model is provided along a conveying direction LA and includes a waiting station LA1, a measuring station LA2 and an output station LA3. The measuring station LA2 is located between the waiting station LA1 and the output station LA3.

[0056] For example, the raised floor flatness measuring device 50 is suitable for transmitting data such as... Figure 2 The raised floor 40 is shown, and the flatness of the top plate 42 of the raised floor 40 is measured. The raised floor 40 is input from the waiting station LA1 to the measuring station LA2, where the flatness of the top plate 42 of the raised floor 40 is measured. After the flatness is measured, the raised floor 40 is then transmitted to the output station LA3.

[0057] It should be noted that the raised floor 40 of this utility model has a rectangular shape and has a top panel 42 and four side panels 44. These side panels 44 are vertically connected to the four sides of the top panel 42. The dimensions of the raised floor 40 of this utility model are, for example, 600 mm × 600 mm × 60 mm, and it is made of, for example, die-cast aluminum alloy.

[0058] The raised floor flatness measuring device 50 includes a conveying device 51, a measuring device 52, a positioning device 53, a raised floor lifting device 54, and selectively configured multiple limiting devices 55 and at least one removal positioning element 56, wherein the conveying device 51 is used to convey the raised floor along the conveying direction LA. Figure 2 The raised floor 40 shown includes a conveying device 51 comprising a first frame 511, a second frame 512, and a conveying structure 514.

[0059] The conveying structure 514 in the conveying device 51 has a conveying direction LA, and along the conveying direction LA, it may include a waiting station LA1, a measuring station LA2, and an output station LA3. The first frame 511 and the second frame 512 are respectively located under the conveying structure 514. The first frame 511 is located at the waiting station LA1 in the conveying structure 514, and the second frame 512 is located at the output station LA3 in the conveying structure 514.

[0060] The measuring device 52, positioning device 53, and lifting device 54 of the raised floor are all located at measuring station LA2 in the conveying structure 514, such that the measuring device 52, positioning device 53, and lifting device 54 of the raised floor are all located between the first frame 511 and the second frame 512. Thus, the conveying structure 514 can transport... Figure 2 The raised floor 40 shown is transferred from the first frame 511 located at the waiting station LA1 to the second frame 512 at the output station LA3.

[0061] In one embodiment, the conveying structure 514 may be a chain transmission drive structure, which includes a main body 5142, a chain assembly 5144, a plurality of gear assemblies including a first gear assembly 5146A and a second gear assembly 5146B, and a drive motor 5148. The main body 5142 is, for example, a frame, with a first frame 511 and a second frame 512 respectively located below the main body 5142. The first gear assembly 5146A and the second gear assembly 5146B are respectively located at both ends of the main body 5142, and the chain assembly 5144 is connected to the first gear assembly 5146A and the second gear assembly 5146B respectively. The drive motor 5148 is connected to the second gear assembly 5146B.

[0062] When the drive motor 5148 drives the second gear assembly 5146B, the first gear assembly 5146A and the second gear assembly 5146B rotate synchronously. At the same time, the first gear assembly 5146A and the second gear assembly 5146B can drive the chain assembly 5144 to move, so that the chain assembly 5144 can move along the conveying direction LA.

[0063] In one embodiment, such as Figure 2 The rear side 46 of the raised floor 40 shown can be placed on the chain assembly 5144, and the raised floor 40 is transported from the waiting station LA1 to the output station LA3 by the chain assembly 5144. The rear side 46 refers to the side opposite to the top plate 42, that is, the top plate 42 of the raised floor 40 does not contact the chain assembly 5144. When the raised floor 40 is transported to the measuring station LA2 by the chain assembly 5144, the raised floor 40 is located between the chain assembly 5144 and the measuring device 52, that is, the top plate 42 of the raised floor 40 will be located below the measuring device 52.

[0064] The first gear assembly 5146A and the second gear assembly 5146B of this invention are, for example, two gears, and are disposed at both ends of the main body 5142. The two chain assemblies 5144 are respectively disposed on the main body 5142. The chain assembly 5144 may include a chain, guide groove, rollers, etc., but this invention does not limit the structure of the chain assembly 5144. The drive motor 5148 may include a chain to connect to the second gear assembly 5146B, so that the drive motor 5148 drives the second gear assembly 5146B to rotate. Simultaneously, when the second gear assembly 5146B rotates, it drives the chain assembly 5144 to rotate. The rotation of the chain assembly 5144 drives the first gear assembly 5146A to rotate, so that the first gear assembly 5146A and the second gear assembly 5146B can rotate synchronously, achieving the purpose of the conveying device 51 being able to carry at least one raised floor 40 and convey the raised floor 40 along the conveying direction LA.

[0065] Furthermore, in one embodiment, the raised floor flatness measuring device 50 can be selectively equipped with a limiting device 55 to... Figure 1 For example, two limiting devices 55 are located at the waiting station LA1, and these two limiting devices 55 are respectively set on both sides of the conveying structure 514, and the setting height of these two limiting devices 55 can be higher than the setting height of the chain assembly 5144.

[0066] The limiting device 55 ensures that the raised floor 40 is restrained and positioned above the chain assembly 5144, allowing the raised floor 40 to operate normally on the conveyor 51. The limiting device 55 is, for example, a plate, and can be positioned at any location on the conveyor 51, depending on the actual situation. That is, in addition to the example of setting the limiting device 55 at the waiting station LA1, it can also be set at the measuring station LA2 or the output station LA3.

[0067] In one embodiment, the conveying device 51 further includes a support frame 513 located between the first frame 511 and the second frame 512, and the support frame 513 is located at the measuring station LA2 in the conveying structure 514. The measuring device 52, the positioning device 53, and the lifting device 54 of the raised floor are all respectively disposed above the support frame 513, such that the measuring device 52, the positioning device 53, and the lifting device 54 of the raised floor are all located above the chain assembly 5144 in the conveying structure 514, and the measuring device 52 is disposed above the positioning device 53 and the lifting device 54 of the raised floor.

Figure 5 This is a perspective view of a reverse embodiment of the measuring device according to the present invention. Figure 6A This is a side view of an embodiment of the measuring device according to the present invention. Figure 6B This is a side view of another embodiment of the measuring device according to the present invention. Please refer to... Figure 1 , Figures 4 to 6B The measuring device 52 of this invention is located at measuring station LA2 in the conveying structure 514, and the measuring device 52 is mounted on the chain assembly 5144. For example, as Figure 1 As shown, four connecting columns 5132 are connected to the support frame 513, and the bottom of the measuring device 52 is connected to these four connecting columns 5132 respectively, so that the measuring device 52 is located above the support frame 513. In addition, in one embodiment, both ends of each crossbar 5134 are connected and fixed to the support frame 513 to stabilize the position of the support frame 513.

[0069] The measuring device 52 includes a sensor mounting plate 522, multiple sensors 524, multiple probes 526, and four plate zero-point positioning blocks 528. The sensor mounting plate 522 is a plate body containing a receiving portion S1 and a detection surface S2. The multiple sensors 524, such as 37 sensors 524, are respectively disposed at different positions in the receiving portion S1. Five sensors 524 are arranged around the perimeter, totaling 25 sensors 524. Within these 25 perimeter sensors 524, 17 additional sensors 524 are arranged to measure and simulate... Figure 2 The ceiling panels 42 of the raised floor 40 shown are evenly distributed at different locations. And, as... Figure 4 As shown, different areas can be set within the accommodating part S1, and an appropriate number of sensors 524 can be installed accordingly, depending on the actual situation. Of course, the number of sensors 524 can be adjusted according to the actual size or requirements of the ceiling 42 of the raised floor 40 being measured.

[0070] The number of probes 526 is the same as the number of sensors 524. Each probe 526 is connected to a sensor 524, meaning the position of each probe 526 corresponds to the position of the sensor 524, and one end of each probe 526 protrudes from the detection surface S2 of the sensor mounting plate 522. These probes 526 face the surface used for contacting... Figure 2 The data obtained by the probes 526 on the ceiling 42 of the raised floor 40 shown is received by the corresponding sensors 524. These sensors 524 can receive this data and display it through a back-end control platform (not shown). The data of each probe 526 is recorded so that it can be determined where there is unevenness in the ceiling 42 of the raised floor 40.

[0071] In one embodiment, the sensor 524 and its corresponding probe 526 are arranged in an array, such that the probe 526 can be arranged in a specific manner, such as by row, column, or other specified order. In a further embodiment, five sensors 524 and five corresponding probes 526 are arranged around the perimeter. Within these perimeter probes, three rows are arranged: the first and third rows each contain six probes 526, arranged in two rows, and the second row contains five probes 526. For example, by using these probes 526 to detect data at different positions of the ceiling 42 of the raised floor 40, the flatness deviation of the ceiling 42 of the overall raised floor 40 is calculated. The worst data at a certain position is taken as the flatness of that ceiling 42. The data must be within the standard value to be considered acceptable; for example, the standard error is ±2 / 10 mm. A deviation exceeding ±2 / 10 mm is considered unacceptable.

[0072] These four zero-point positioning blocks 528 are respectively located at the four corners of the detection surface S2 of the sensor mounting plate 522. For ease of explanation, the zero-point positioning blocks 528 at different positions are referred to as the first zero-point positioning block SP1, the second zero-point positioning block SP2, the third zero-point positioning block SP3, and the fourth zero-point positioning block SP4. The first zero-point positioning block SP1, the second zero-point positioning block SP2, the third zero-point positioning block SP3, and the fourth zero-point positioning block SP4 are located at the four corners of these probes 526, so that the size range formed by the first zero-point positioning block SP1, the second zero-point positioning block SP2, the third zero-point positioning block SP3, the fourth zero-point positioning block SP4, and these probes 526 can cover the following... Figure 2 The ceiling 42 of the raised floor 40 shown.

[0073] Furthermore, the detection surface S2 of the sensor mounting plate 522 can be provided with four fixing parts B1. These four fixing parts B1 can be, for example, through holes for locking elements, to accommodate... Figure 1 or Figure 3 The connecting posts 5132 shown are connected together.

[0074] Figure 7 This is a perspective view of the positioning device and the lifting device for the raised floor according to the present invention. Figure 8 This is a top view of the positioning device and the lifting device for the raised floor according to the present invention. Figure 9 This is a side view of the positioning device and the lifting device for the raised floor according to this utility model. Please refer to... Figure 2 , Figure 3 , Figures 7 to 9 The conveying device 51 is used to convey the raised floor 40 to the measuring station LA2 along the conveying direction LA. The positioning device 53 is used to position the side plate 44 of the raised floor 40 so that the position of the top plate 42 can be positioned on the measuring device 52 so that the position of the top plate 42 corresponds to the position of the detection surface S2 of the sensor mounting plate 522.

[0075] The positioning device 53 of this utility model is located at measuring station LA2. The positioning device 53 includes a first positioning element T1, a second positioning element T2, a third positioning element T31, a fourth positioning element T32, a fifth positioning element T4, a first push cylinder T11, and a second push cylinder T21. The first positioning element T1, the first push cylinder T11, the second positioning element T2, and the second push cylinder T21 are arranged along the conveying direction LA. The first push cylinder T11 is connected to the first positioning element T1, and the second push cylinder T21 is connected to the second positioning element T2. At least one positioning element is arranged on each side of the conveying direction LA to... Figure 3For example, two positioning elements, the third positioning element T31 and the fourth positioning element T32, are set on the left side of the conveying direction LA, and a fifth positioning element T4 is set on the right side of the conveying direction LA. It also functions as a push cylinder, which can push the raised floor 40 toward the third positioning element T31 and the fourth positioning element T32 for positioning.

[0076] The first positioning element T1, the second positioning element T2, the first push cylinder T11, and the second push cylinder T21 are all located between the two chain assemblies 5144 in the conveying structure 514. The third positioning element T31 and the fourth positioning element T32 are located on one side of the two chain assemblies 5144 in the conveying structure 514, while the fifth positioning element T4 is located on the other side of the two chain assemblies 5144 in the conveying structure 514. That is, the third positioning element T31, the fourth positioning element T32, and the fifth positioning element T4 are located on opposite sides of the first positioning element T1 and the second positioning element T2.

[0077] Along the conveying direction LA, the second positioning element T2 and its connected second push cylinder T21 are adjacent to the waiting station LA1, and the first positioning element T1 and its connected first push cylinder T11 are adjacent to the output station LA3. That is to say, when the raised floor 40 is conveyed to the measuring station LA2 by the chain assembly 5144, the raised floor 40 will first be conveyed by the second positioning element T2 and its connected second push cylinder T21, and then by the first positioning element T1 and its connected first push cylinder T11. During the process of the raised floor 40 being conveyed from the second positioning element T2 to the first positioning element T1, the third positioning element T31, the fourth positioning element T32 and the fifth positioning element T4 are located on both sides of the raised floor 40, and the measuring device 52 is located on the upper side of the top plate 42 of the raised floor 40.

[0078] Please see Figure 3 , Figure 7 , Figure 9 The third positioning element T31, the fourth positioning element T32, and the fifth positioning element T4 are positioned at a higher height than the chain assembly 5144, so that the conveyed object (such as...) Figure 2 When the elevated floor 40 passes through, the third positioning element T31, the fourth positioning element T32 and the fifth positioning element T4 on both sides of the chain assembly 5144 can be positioned on the conveyed object (such as... Figure 2 The left and right sides of the raised floor (40).

[0079] The height of the first push cylinder T11 and the second positioning element T2 is not higher than the height of the chain assembly 5144, so that the conveyed object (such as...) Figure 2When the elevated floor 40 passes under the chain assembly 5144, it will not collide with the first push cylinder T11 or the second positioning element T2. However, driven by the first push cylinder T11 and the second push cylinder T21 by the second positioning element T2, the first positioning element T1 and the second positioning element T2 can protrude from the set height position of the chain assembly 5144, so that the first positioning element T1 and the second push cylinder T21 can be positioned at the location of the conveyed object (such as...). Figure 2 The raised floor 40 is positioned on the front and rear sides, allowing the first positioning element T1 and the second push cylinder T21 to not protrude beyond the set height of the chain assembly 5144, thus providing space for the conveyed object (such as...) Figure 2 The elevated floor 40) is measured at station LA2.

[0080] Specifically, the first positioning element T1 includes a positioning plate 532, a rack 533, and a circular gear 534, wherein, as shown in the figure... Figure 9 As shown, one end of the rack 533 is connected to the first push cylinder T11, and the other end of the rack 533 is connected to the circular gear 534. The circular gear 534 is connected to the positioning plate 532. With this structure, the first push cylinder T11 pushes the rack 533, causing the rack 533 to drive the circular gear 534 to rotate, thereby positioning the positioning plate 532. Figure 9 The indicated positioning position or retracted position (e.g.) Figure 9 The dotted line indicates the positioning plate 532), and the positioning plate 532 is located at... Figure 3 The positioning position shown is set at a height higher than the setting height of the chain assembly 5144, and is used to contact the conveyed object (such as...). Figure 2 One side of the raised floor 40) blocks its advance for positioning purposes; conversely, if it is as follows... Figure 9 The dashed line indicates the positioning plate 532. Figure 9 The dashed line indicates that the setting height of the positioning plate 532 is not higher than the setting height of the chain assembly 5144.

[0081] like Figure 3 As shown, the second push cylinder T21 is positioned no higher than the height of the chain assembly 5144. In one embodiment, as... Figure 9 As shown, driven by the second positioning element T2, the second push cylinder T21 can move up and down in a lifting direction LB, so that the second push cylinder T21 can be positioned as shown. Figure 3In addition to the origin position shown, the second push cylinder T21 can also protrude beyond the setting position of the chain assembly 5144, such that the setting height of the second push cylinder T21 is higher than the setting height of the chain assembly 5144. In one embodiment, the second push cylinder T21 includes two contact members 538, which are used to contact the conveyed object (such as...) when the setting height of the second push cylinder T21 is higher than the setting height of the chain assembly 5144. Figure 2 On the other side of the raised floor 40, it is used for positioning.

[0082] The third positioning element T31, the fourth positioning element T32, and the fifth positioning element T4 are located on both sides of the two chain assemblies 5144 in the conveying structure 514. Taking the third positioning element T31 as an example, the third positioning element T31 includes a push cylinder 535 and a circular roller 536. The push cylinder 535 is connected to the circular roller 536. The fourth positioning element T32 and the fifth positioning element T4 have the same structure as the third positioning element T31, and also include a push cylinder 535 and a circular roller 536. In this structure, the push cylinder 535 pushes the circular roller 536, so that the circular roller 536 can move towards the chain assembly 5144. The circular roller 536 is used to contact the conveyed object (such as...). Figure 2 The raised floor 40) is located on the left and right sides for positioning purposes.

[0083] In addition, such as Figure 1 As shown, in addition to the positioning mechanism located at the measuring station LA2, in one embodiment, the positioning element 56 is located at the output station LA3, which can be used to locate the transported object (such as...). Figure 2 The raised floor 40) is used for positioning when it is removed. The structure of the positioning element 56 can be the same as that of the aforementioned third positioning element T31.

[0084] Please refer to the following: Figure 3 , Figures 7 to 9 The lifting device 54 of the elevated floor of this utility model is located at the measuring station LA2 and is used to lift such as Figure 2 The raised floor 40 is shown. The lifting device 54 of the raised floor includes four lifting mechanisms 100 and a drive motor GM. The lifting mechanisms 100 are used to support and lift the floor as shown. Figure 2 The raised floor 40 shown has a rear side 46, where a support base 57 is located above the support frame 513. A drive motor GM is fixed to the support base 57. The drive motor GM drives the four lifting mechanisms 100 to move synchronously along the lifting direction LB, so as to... Figure 2 The raised floor 40 shown moves along the lifting direction LB to move the raised floor 40 away from the... Figure 1The chain assembly 5144 is shown and is located near the measuring device 52. Since the four lifting mechanisms 100 are supported at the four corners of the raised floor 40, they can be raised and lowered smoothly. In other embodiments, each of the four lifting mechanisms 100 may have its own drive mechanism, which, by setting the torque, allows the four lifting mechanisms 100 to be simultaneously raised to a predetermined position.

[0085] Figure 10 This is a perspective view of an embodiment of the raised floor lifting device according to the present invention. Please refer to... Figure 10 The raised floor lifting device 54 of this utility model includes four lifting mechanisms 100, a drive motor GM, a belt 542, two first support plates 544, and two second support plates 545. The two ends of the two first support plates 544 are respectively connected to the two second support plates 545. The two first support plates 544 and the two second support plates 545 are connected to form a square frame, which moves synchronously upwards and downwards in a linear motion with four screws G13. This allows the screws G13 in the four lifting mechanisms 100 to synchronously drive the contact blocks D12 of the raised floor lifting device 54 to contact the four corners of the raised floor synchronously. The positions of the four lifting mechanisms 100 can correspond to... Figure 5 The positions of the first plate zero-point positioning block SP1, the second plate zero-point positioning block SP2, the third plate zero-point positioning block SP3, and the fourth plate zero-point positioning block SP4 in the measuring device 52 shown are such that the four lifting mechanisms 100 synchronously move the raised floor 40 along the lifting direction LB and contact the first plate zero-point positioning block SP1, the second plate zero-point positioning block SP2, the third plate zero-point positioning block SP3, and the fourth plate zero-point positioning block SP4.

[0086] The drive motor GM is located between two of the lifting mechanisms 100. A belt 542 is wound around the drive pulleys 151 of these four lifting mechanisms 100 and the drive motor GM to form a synchronous drive mechanism. The contact blocks D12 of these four lifting mechanisms 100 correspond to... Figure 5 The positions of the first plate zero-point positioning block SP1, the second plate zero-point positioning block SP2, the third plate zero-point positioning block SP3, and the fourth plate zero-point positioning block SP4 in the measuring device 52 shown.

[0087] In this way, the drive motor GM can drive the belt 542 to rotate, and the belt 542 can drive the transmission pulleys 151 of the four lifting mechanisms 100, so that the contact blocks D12 of the four lifting mechanisms 100 can perform lifting actions. Since the four lifting mechanisms 100 are driven by the same drive source (drive motor GM) and transmission structure (belt 542) to perform lifting actions synchronously, the contact blocks D12 can be raised or lowered to a predetermined position, thus avoiding the generation of position differences in the upward movement of the four lifting mechanisms 100.

[0088] In one embodiment, the lifting mechanism 100 may include two independent lifting modes: a fast lifting module G1, G2, G3, G4 and a slow lifting module D1, D2, D3, D4. Besides synchronously executing the lifting actions of these four lifting mechanisms 100, the fast lifting modules G1, G2, G3, G4 can simultaneously and rapidly raise the height of these four lifting mechanisms 100. Furthermore, the slow lifting modules D1, D2, D3, D4 can supplement the fast lifting modules G1, G2, G3, G4 to enhance the fit against the four corners of the raised floor 40.

[0089] Figure 11 This is a schematic diagram of an embodiment of the lifting device for raised floors according to the present invention in the lifting position. It illustrates that the lifting device 54 of the raised floor is in the lifting position P1 to raise the height of the raised floor 40. The lifting position P1 includes the lifting position P11 of the fast lifting modules G1, G2, G3, G4 and the lifting position P12 of the slow lifting modules D1, D2, D3, D4. Figure 12 This is a schematic diagram of an embodiment of the lifting device for raised floors according to the present invention at the origin position. It illustrates the origin position P2 of the raised floor 40 before it is lifted by the lifting device 54. The origin position P2 includes the origin position P21 of the fast lifting modules G1, G2, G3, and G4 and the origin position P22 of the slow lifting modules D1, D2, D3, and D4.

[0090] Please see Figure 11 and Figure 12 Each slow lifting module D1, D2, D3, D4 of this invention is connected to and positioned above the corresponding fast lifting modules G1, G2, G3, G4 of the lifting mechanism 100. The fast lifting module G1 includes a T-nut connector G11, a connecting flange G12, and a screw G13. One end of each of the four screws G13 is fixed to one end of the first support plate 544. In this way, the aforementioned belt 542 drives the transmission wheel 151 to rotate, synchronously driving the inner transmission wheel connector 152 of the transmission wheel 151 and its connected T-nut 153 (e.g., ...). Figure 15A( ) Rotation. At this time, since the first support plate 544 and the second support plate 545 at the bottom of the four screws G13 are fixed ends, the screws G13 cannot be rotated. The transmission wheel 151 synchronously drives the transmission wheel connector 152 and its connected T-nut 153 to rotate. The T-nut 153 can drive the screws G13 to make up-down linear motion, such as Figure 11 The lifting position P11 shown drives the slow lifting modules D1, D2, D3, and D4 and their connected contact block D12 to raise their height, thereby raising the raised floor 40 to its height position. The transmission wheel 151 synchronously drives the transmission wheel connector 152 and its connected T-nut 153 to rotate. The T-nut 153 drives the screw G13 to move vertically, rapidly driving the screw G13 to rise linearly. In other words, the rotational motion of the T-nut 153 is converted into the linear motion of the screw G13 to quickly achieve the raised position. In conjunction with the aforementioned method of simultaneously driving these four lifting mechanisms 100 through a single power source (drive motor GM), the elevated floor 40 is raised to a predetermined height in a synchronized and rapid manner. This avoids positional differences caused by the different lifting positions of the four lifting mechanisms 100, thereby ensuring that all four corners of the elevated floor 40 can be raised smoothly by these four lifting mechanisms 100, avoiding height differences at the four corners of the elevated floor 40, and preventing the elevated floor 40 from slipping during the lifting process.

[0091] Conversely, such as Figure 12 As shown, it can be used in conjunction with the aforementioned transmission wheel 151 to synchronously drive the transmission wheel connector 152 and its connected T-nut 153 to rotate in the opposite direction, so that the protruding end 142 of the screw G13 and its pivotally connected connecting flange G12 are reset to the position shown. Figure 12 The origin position P21 shown is used to drive the slow lifting modules D1, D2, D3, D4 and their connected contact block D12 to reset to their height position.

[0092] In addition to the aforementioned rapid lift modules G1, G2, G3, and G4, please refer to [link to other modules]. Figure 11 and Figure 12The slow-speed lifting modules D1, D2, D3, and D4 of this invention include a contact block D12 and a cylinder power source D11. The cylinder power source D11 is connected to the contact block D12, and a gasket 111 is fixed to the contact block D12. The other end of the cylinder power source D11 is connected to the fast-speed lifting modules G1, G2, G3, and G4. The function of the slow-speed lifting modules D1, D2, D3, and D4 of this invention is to compensate for the gaps generated between the components of the fast-speed lifting modules G1, G2, G3, and G4, the thickness tolerances generated during the processing of the four corners of the raised floor 40, and the total errors caused by various factors including but not limited to measuring tools. As a result, the four corner surfaces of the raised floor 40 cannot completely fit the positions of the first plate zero-point positioning block SP1, the second plate zero-point positioning block SP2, the third plate zero-point positioning block SP3, and the fourth plate zero-point positioning block SP4 in the measuring device 52. Utilizing the controllability of the air pressure of the cylinder power source D11, the cylinder power source D11 drives the contact block D12 to move, thereby adjusting the height position of the raised floor 40.

[0093] Because the cylinder output can be adjusted according to the weight of the raised floor 40, and by utilizing air pressure regulation control and the limited infinite position function of the cylinder, the raised floor 40 can be lifted with the most appropriate force so that the four corner surfaces of the raised floor 40 are completely in contact with the positions of the first plate zero-point positioning block SP1, the second plate zero-point positioning block SP2, the third plate zero-point positioning block SP3, and the fourth plate zero-point positioning block SP4 in the measuring device 52, thereby achieving the effectiveness and accuracy of the flatness measurement value.

[0094] To ensure the probe 526 of the measuring device 52 returns to its original position, a zeroing calibration is performed on the probe 526 before measuring the flatness of the raised floor. The following example illustrates the zeroing calibration process for the automatic flatness measurement of the raised floor according to this invention: First, a high-precision gauge block is selected, with dimensions, for example, 600mm × 600mm × 60mm. In one embodiment, the structure and dimensions of the high-precision gauge block are as follows... Figure 2 The raised floor 40 shown is the same. Place the high-precision gauge block into the... Figure 1 The waiting station LA1 shown uses the chain assembly 5144 in the conveying device 51 to move the high-precision gauge block to the measuring station LA2, so that the high-precision gauge block is located below the measuring device 52.

[0095] Next, when the front side of the high-precision gauge block touches... Figure 3When the positioning plate 532 in the first positioning element T1 is activated, the chain assembly 5144 stops conveying the high-precision gauge block. Then, the third positioning element T31, the fourth positioning element T32, and the fifth positioning element T4 located on both sides of the chain assembly 5144 begin to operate. The circular gears 536 of the third and fourth positioning elements T31 and T32 extend and move towards the high-precision gauge block to position its left side. The circular gear 536 of the fifth positioning element T4 extends and moves towards the right side of the high-precision gauge block (i.e., towards the third and fourth positioning elements T31 and T32) to push the high-precision gauge block towards the third and fourth positioning elements T31 and T32, allowing it to come into close contact with them. In other words, the left and right sides of the high-precision gauge block are positioned by the third, fourth, and fifth positioning elements T31 and T32. Finally, the second positioning element T2 drives the second push cylinder T21 to move, causing the second push cylinder T21 to protrude from the setting position of the chain assembly 5144 and move towards the high-precision gauge block, that is, towards the first positioning element T1. The contact member 538 of the second push cylinder T21 contacts the high-precision gauge block, so that the high-precision gauge block can be pushed towards and close to the positioning plate 532 in the first positioning element T1. In this way, the high-precision gauge block is positioned by the first positioning element T1, the second push cylinder T21, the third positioning element T31, the fourth positioning element T32 and the fifth positioning element T4 in the positioning device 53, so as to complete the positioning of the high-precision gauge block.

[0096] Next, as Figure 9 As shown, the rack 533 is pushed by the first push cylinder T11, causing the rack 533 to drive the circular gear 534 to rotate, thereby positioning the positioning plate 532. Figure 9 The indicated positioning position is rotated back to the retracted position (e.g., Figure 9 The positioning plate 532 is indicated by the dashed line; on the other hand, the second push cylinder T21 is retracted to the original position by the second positioning element T2, that is, the setting height position of the second positioning element T2 is not higher than the setting height position of the chain assembly 5144; in addition, the third positioning element T31, the fourth positioning element T32 and the fifth positioning element T4 located on both sides of the chain assembly 5144 start to operate, retract to the original position, so as to move away from the high-precision gauge block, so as to complete the reset action of all positioning devices 53.

[0097] Next, as Figure 10As shown, the drive motor GM is actuated, which drives the belt 542 to rotate. The belt 542 drives the transmission wheel 151 of each lifting mechanism 100, so that the rapid lifting modules G1, G2, G3 and G4 in each lifting mechanism 100 can synchronously and rapidly raise the height of the four lifting mechanisms 100, so that the high-precision gauge block can be lifted to a predetermined height by the four lifting mechanisms 100.

[0098] After the high-precision gauge block is lifted to a predetermined height by the rapid lifting modules G1, G2, G3, and G4, it is then lifted by the slow lifting modules D1, D2, D3, and D4 to bring its upper surface into contact with the positions of the first plate zero-point positioning block SP1, the second plate zero-point positioning block SP2, the third plate zero-point positioning block SP3, and the fourth plate zero-point positioning block SP4 in the measuring device 52. At this time, the first plate zero-point positioning block SP1, the second plate zero-point positioning block SP2, the third plate zero-point positioning block SP3, and the fourth plate zero-point positioning block SP4 are located at the four corners of these probes 526. Therefore, when the upper surface of the high-precision gauge block contacts the first plate zero-point positioning block SP1, the second plate zero-point positioning block SP2, the third plate zero-point positioning block SP3 and the fourth plate zero-point positioning block SP4 in the measuring device 52, the probe 526 in the measuring device 52 will also touch the upper surface of the high-precision gauge block.

[0099] Finally, after confirming that all probes 526 have touched the upper surface of the high-precision gauge block, the data obtained by these probes 526 is received by the corresponding sensors 524. These sensors 524 can receive this data and display it through a back-end control platform (such as a BCS display), and reset all the data obtained by the probes 526 to zero, so as to complete the zeroing correction action of the automatic measurement of the flatness of the raised floor.

[0100] Subsequently, the slow lifting modules D1, D2, D3, D4 and the fast lifting modules G1, G2, G3, G4 are reset, so that the high-precision gauge block is once again located in the two chain assemblies 5144 of the conveying structure 514. Then, the high-precision gauge block is transported from the measuring station LA2 to the output station LA3 via the chain assembly 5144. Then, the first push cylinder T11 pushes the rack 533, causing the rack 533 to drive the circular gear 534 to rotate, so as to place the positioning plate 532 in... Figure 9 The retracted position shown is rotated back to the positioning position (e.g., Figure 9 The solid line indicates the positioning plate 532, which is used to receive the next calibration work.

[0101] After the aforementioned zeroing correction action of the automatic flatness measurement of the raised floor, the position data of the probe 526 in the measuring device 52 is zero, which serves as the reference for the flatness of the subsequent raised floor ceiling. The following example illustrates the automatic measurement action of the raised floor surface flatness of this invention: First, the… Figure 2 The raised floor 40 shown is placed in, as... Figure 1 The waiting station LA1, as shown, uses a chain assembly 5144 in the conveyor 51 to move the raised floor 40 to the measuring station LA2, so that the raised floor 40 is located below the measuring device 52, and the top plate 42 faces the detection surface S2 of the measuring device 52. The probes 526 face the surface used for contact with... Figure 2 The ceiling 42 of the raised floor 40 shown.

[0102] Next, when the front side of the raised floor 40 touches... Figure 3 When the positioning plate 532 in the first positioning element T1 is activated, the chain assembly 5144 stops conveying the raised floor 40. Then, the third positioning element T31, the fourth positioning element T32, and the fifth positioning element T4 located on both sides of the chain assembly 5144 begin to operate. The circular rollers 536 of the third and fourth positioning elements T31 and T32 extend and move towards both sides of the raised floor 40 to position the left side of the raised floor 40. The circular roller 536 of the fifth positioning element T4 extends and moves towards the right side of the raised floor 40 (i.e., towards the third and fourth positioning elements T31 and T32) to push the raised floor 40 towards the third and fourth positioning elements T31 and T32, so that the raised floor 40 is close to the third and fourth positioning elements T31 and T32. In other words, the left and right sides of the raised floor 40 are positioned by the third, fourth, and fifth positioning elements T31 and T32. Finally, the second positioning element T2 drives the second push cylinder T21 to move, causing the second push cylinder T21 to protrude from the setting position of the chain assembly 5144 and move towards the raised floor 40, that is, towards the first positioning element T1. The contact member 538 of the second push cylinder T21 contacts the raised floor 40, so that the raised floor 40 can be pushed towards and close to the positioning plate 532 in the first positioning element T1. In this way, the raised floor 40 is positioned by the first positioning element T1, the second push cylinder T21, the third positioning element T31, the fourth positioning element T32 and the fifth positioning element T4 in the positioning device 53, so as to complete the positioning of the raised floor 40.

[0103] Next, as Figure 9 As shown, the rack 533 is pushed by the first push cylinder T11, causing the rack 533 to drive the circular gear 534 to rotate, thereby positioning the positioning plate 532. Figure 9The indicated positioning position is rotated back to the retracted position (e.g., Figure 9 The positioning plate 532 is indicated by the dashed line; on the other hand, the second push cylinder T21 is retracted to the original position by the second positioning element T2, that is, the setting height of the second positioning element T2 is not higher than the setting height of the chain assembly 5144; in addition, the third positioning element T31, the fourth positioning element T32 and the fifth positioning element T4 located on both sides of the chain assembly 5144 start to operate, retract to the original position, and move away from the raised floor 40 to complete the reset action of all positioning devices 53.

[0104] Next, as Figure 10 and Figure 11 As shown, the drive motor GM is actuated, which drives the belt 542 to rotate. The belt 542 drives the transmission wheel 151 of each lifting mechanism 100, so that the rapid lifting modules G1, G2, G3 and G4 in each lifting mechanism 100 can synchronously and rapidly raise the height of the four lifting mechanisms 100, so that the raised floor 40 can be lifted to a predetermined height by the four lifting mechanisms 100.

[0105] After the raised floor 40 is lifted to a predetermined height by the rapid lifting modules G1, G2, G3, and G4, the slow lifting modules D1, D2, D3, and D4 then lift the top plate 42 of the raised floor 40 to contact the positions of the first plate zero-point positioning block SP1, the second plate zero-point positioning block SP2, the third plate zero-point positioning block SP3, and the fourth plate zero-point positioning block SP4 in the measuring device 52. At this time, the first plate zero-point positioning block SP1, the second plate zero-point positioning block SP2, the third plate zero-point positioning block SP3, and the fourth plate zero-point positioning block SP4 are located at the four corners of these probes 526. Therefore, when the top plate 42 of the raised floor 40 contacts the first plate zero-point positioning block SP1, the second plate zero-point positioning block SP2, the third plate zero-point positioning block SP3 and the fourth plate zero-point positioning block SP4 in the measuring device 52, the probe 526 in the measuring device 52 will also touch the top plate 42 of the raised floor 40.

[0106] Finally, the data obtained by these probes 526 is received by the corresponding sensors 524. These sensors 524 can receive this data and display it through a back-end control platform (such as a BCS display) to complete the automatic measurement of the flatness of the raised floor surface, calculate the flatness deviation of the roof panel 42 of the overall raised floor 40, and the worst data at a certain location can be used as the flatness of that roof panel 42.

[0107] Subsequently, the slow lifting modules D1, D2, D3, D4 and the fast lifting modules G1, G2, G3, G4 are reset, so that the elevated floor 40 is once again located in the two chain assemblies 5144 of the conveying structure 514. Then, the elevated floor 40 is transported from the measuring station LA2 to the output station LA3 via the chain assemblies 5144. Then, the first push cylinder T11 pushes the rack 533, so that the rack 533 drives the circular gear 534 to rotate, thereby positioning the positioning plate 532. Figure 9 The retracted position shown is rotated back to the positioning position (e.g., Figure 9 The solid line indicates the positioning plate 532, which is used to receive the next measurement.

Figure 15A This is a cross-sectional schematic diagram of an embodiment of the lifting mechanism according to the present invention in the lifting position. Figure 15B This is a cross-sectional schematic diagram of an embodiment of the lifting mechanism according to this utility model at the origin position. Please refer to... Figures 13A to 15B ,in Figure 13A , Figure 15A The lifting position P1 of the lifting mechanism 100 can correspond to Figure 11 The lifting mechanism 100 in the middle has a lifting position P1 including the lifting positions P11 of the fast lifting modules G1, G2, G3, and G4 and the lifting positions P12 of the slow lifting modules D1, D2, D3, and D4. Figure 13B , Figure 15B The origin position P2 can be mapped to Figure 12 The lifting mechanism 100 in the middle has an origin position P2 that includes the origin positions P21 of the fast lifting modules G1, G2, G3, and G4 and the origin positions P22 of the slow lifting modules D1, D2, D3, and D4.

[0109] The lifting mechanism 100 includes a fast lifting module G1, a slow lifting module D1, and a T-shaped connector E1. The lifting mechanism 100 includes two independent lifting modes: a fast lifting module G1 and slow lifting modules D1, D2, D3, and D4. The fast lifting modules G1, G2, G3, and G4 can quickly lift to a predetermined height. The slow lifting modules D1, D2, D3, and D4 are fixed above the fast lifting modules G1, G2, G3, and G4, and lift synchronously with them. The fast lifting module G1 includes a T-shaped nut connector G11, a connecting flange G12, and a screw G13. The slow lifting module D1 includes a cylinder power source D11, a contact block D12, and a T-shaped connector E1.

[0110] The T-nut connector G11 includes a drive wheel 151, a drive wheel connector 152, a T-nut 153, a bearing housing 154, at least one bearing 155, a nut 156, a retainer 157, a C-ring 158, and two deep groove bearings 159. The number of bearings 155 can be adjusted according to the structural configuration.

[0111] A transmission wheel connector 152 is provided inside the transmission wheel 151. One side of the T-nut 153 is connected to the transmission wheel connector 152. The T-nut 153 can be fixed together with the transmission wheel 151 and rotate synchronously through the transmission wheel connector 152.

[0112] In one embodiment, a T-nut 153 is placed inside the bearing housing 154. The T-nut 153 is an elongated through-hole with an external thread at its upper end, and its lower end is connected and fixed to the drive wheel 151 for rotation. For example, when assembling the T-nut connector G11, the shaft of the drive wheel connector 152 is first fitted into the central hole of the drive wheel 151, and the shaft of the T-nut 153 is fitted upwards into the central hole of the bearing housing 154. Then, at least one fixing screw SC is sequentially inserted into the through hole H1 of the drive wheel 151, the through hole H2 of the drive wheel connector 152, and the through hole H3 of the T-nut 153 to lock the drive wheel 151, the drive wheel connector 152, and the T-nut 153 into a single unit, thereby connecting and fixing the drive wheel 151 and the T-nut 153 into a single unit.

[0113] The bearing housing 154 houses the bearing 155, which is located between the T-nut 153 and the bearing housing 154. The nut 156 is locked onto the external thread at the upper end of the T-nut 153 to fix the position of the bearing 155.

[0114] A C-ring clip 158, two deep groove bearings 159, and a retainer 157 are inserted around the outer periphery of the T-nut 153. A deep groove bearing 159 is positioned at each of the upper and lower ends of the retainer 157, which secures the positions of the two deep groove bearings 159. The C-ring clip 158, also known as a circlip or retainer, is an elastic fastener used to secure parts or bearings within a shaft or hole. It typically has a C-shaped or nearly circular structure with openings at both ends. After installation, its elastic force firmly fixes the parts in a predetermined position. In this embodiment, the C-ring clip 158 is located between a deep groove bearing 159 and a bearing 155 to reinforce and secure the position of the bearing 155.

[0115] It should be noted that the Deep Groove Ball Bearing 159 is a type of rolling bearing, characterized by deep, rounded grooves in the raceways of its inner and outer rings, which can withstand radial loads and a certain amount of axial loads.

[0116] The connecting flange G12 includes an upper connecting flange 162 connected to a lower connecting flange 161, with the upper connecting flange 162 positioned above the lower connecting flange 161. In one embodiment, bolts (not shown) are used to pass through through hole H4 to lock the upper connecting flange 162 and the lower connecting flange 161 together.

[0117] The upper end of the screw G13 is fixed to the lower connecting flange 161. The lower end of the screw G13 is sequentially inserted through a nut 156, a T-nut 153, a bearing 155, a drive wheel connector 152, and a drive wheel 151. A first bolt 145 and a bolt head 146 are provided above the T-nut connector G11. In one embodiment, the screw G13 includes an extended end 142. The upper end of the screw G13 is connected and fixed to the lower end of the first bolt 145. The upper end of the first bolt 145 is a bolt head 146. The first bolt 145 passes through a countersink hole 161A in the lower connecting flange 161 and is locked in the screw hole at the upper end of the screw G13 to fix the screw G13 and the lower connecting flange 161 into one unit. The bolt head 146 is fixedly connected to the countersink hole 161A of the lower connecting flange 161. Therefore, the first bolt 145 is fixed to the lower connecting flange 161 by the bolt head 146 at the upper end of the first bolt 145, and the protruding end 142 of the screw G13 is fixed to the lower connecting flange 161 by the first bolt 145. The first bolt 145 and its bolt head 146 are integrally formed into a bolt. Other fasteners can also be used to replace the first bolt 145 and its bolt head 146. This utility model uses a first bolt 145 for fixing.

[0118] In one embodiment, such as Figure 14B As shown, a countersunk hole 161A is provided inside the lower connecting flange 161. The first bolt 145 passes through and is located in the countersunk hole 161A. The countersunk hole 161A is a hole machined into the material surface. Its characteristic is that there is a tapered enlargement at the opening to accommodate the head of the countersunk screw (such as the first bolt 145), so that the head of the first bolt 145 can be flush with or slightly lower than the surface of the lower connecting flange 161. The design of the countersunk hole 161A is mainly for aesthetics and functionality. For example, it avoids the head of the first bolt 145 from protruding, which would affect the flatness or aesthetics of the lower connecting flange 161. In addition, the lower connecting flange 161 with a flat upper surface can be connected and fixed together with the upper connecting flange 162.

[0119] The screw G13 is sequentially threaded through the nut 156, the T-nut 153, and the drive wheel connector 152 on the drive wheel 151. The aforementioned T-nut connector G11, connecting flange G12, and screw G13 constitute a fast lifting module G1. The slow lifting module D1 includes a cylinder power source D11 and a contact block D12, with the contact block D12 connected to the cylinder power source D11.

[0120] One end of the T-connector E1 is connected to the upper connecting flange 162, and the other end of the T-connector E1 is provided with a fixed base 148. The upper connecting flange 162 and the fixed base 148 at both ends of the T-connector E1 are respectively connected and fixed to the fast lifting module G1 and the slow lifting module D1. That is, one end of the T-connector E1 is connected and fixed to the fast lifting module G1 through the upper connecting flange 162, and the other end of the T-connector E1 is connected and fixed to the slow lifting module D1 through the fixed base 148.

[0121] One end of the T-shaped connector E1 is provided with a fixed base 148, and the other end of the T-shaped connector E1 is connected to an upper connecting flange 162. A second bolt 143 is connected to the fixed base 148. The upper end of the T-shaped connector E1 is a fixed base 148. The lower end of the T-shaped connector E1 is an upper connecting flange 162. The upper end of the T-shaped connector E1 is connected and fixed to the bottom of the cylinder power source D11 by the second bolt 143 and the fixed base 148. The second bolt 143 is fixed in the same way as the first bolt 145, that is, the fixed base 148 of the T-shaped connector E1 is provided with a second bolt 143, which is inserted into the bottom of the cylinder power source D11 and locked in the screw hole of the fixed base 148 to connect and fix the cylinder power source D11 to the fixed base 148. Therefore, the bottom of the cylinder power source D11 is connected and fixed to the fixed base 148 on the upper end of the T-shaped connector E1 by the second bolt 143, so that the connecting flanges 162 and the fixed base 148 on both ends of the T-shaped connector E1 are respectively connected and fixed to the fast lifting module G1 and the slow lifting module D1. Other fasteners can also be used to replace the second bolt 143, but this utility model uses the second bolt 143 for fixing.

[0122] When the drive transmission wheel 151 rotates, it synchronously drives the transmission wheel connector 152 inside the transmission wheel 151 and the T-nut 153 connected to it to rotate. The T-nut 153 is fixed inside the transmission wheel 151. When the T-nut 153 rotates, because the screw hole 149 at the bottom end of the screw G13 uses a screw (not shown), it can be fixed to both ends of the support plate 544 (e.g., Figures 10 to 12 As shown), the bottom end of the screw G13 is fixed, preventing it from rotating. The T-nut 153 drives the screw G13 to move vertically. This vertical linear motion (or vertical movement) refers to the movement of the screw G13 along a straight line in the vertical direction. The direction of movement of the screw G13 is up and down, and the movement is along a straight line. Figure 13A or Figure 15A The lifting position P11 shown drives the slow lifting module D1 and its connected contact block D12 to raise its height. The transmission wheel 151 drives the transmission wheel connector 152 and its connected T-nut 153 to rotate, thereby quickly driving the screw G13 to rise linearly, that is, converting the rotational motion into linear motion to quickly achieve the purpose of lifting.

[0123] Conversely, such as Figure 13B or Figure 15B As shown, the T-nut 153 connected to the aforementioned transmission wheel 151 and transmission wheel connector 152 can rotate in the opposite direction, causing the protruding end 142 of the screw G13 and its pivotally connected connecting flange G12 to return to their original positions. Figure 13B or Figure 15B The origin position P21 shown is used to drive the slow lifting module D1 and its connected contact block D12 to reset or lower back to their height position.

[0124] The cylinder power source D11 includes a cylinder body 132, a piston 134, at least one through hole 135, at least one intake and exhaust port 136, and multiple fixed rods 137. The piston 134 is movable within the cylinder body 132. The piston 134 includes a protruding end 134A and a top 134B. The protruding end 134A is connected to the top 134B, and the top 134B is fixed to the bottom of the contact block D12, allowing the cylinder power source D11 to slowly raise and lower the corresponding contact block D12 to adjust the height of the contact block D12. One end of the fixed rod 137 passes through the cylinder body 132, and the other end of the fixed rod 137 is connected to the top 134B, allowing the piston 134 to evenly and balancedly lift the contact block D12 on the multiple fixed rods 137, making slow up-and-down movements. The piston 134 is also linked to the contact block D12 with the fixed rods 137.

[0125] In one embodiment, the cylinder body 132 is fixed to the bottom of the cylinder body 132 by a bolt (not shown) passing through a through hole 135, and at least one intake and exhaust hole 136 is provided on the cylinder body 132.

[0126] The aforementioned cylinder power source D11, contact block D12, and T-shaped connector E1 constitute a slow-speed lifting module D1. Utilizing the controllable air pressure of the cylinder power source D11, the cylinder power source D11 drives the contact block D12 to move, allowing the piston 134 to move within the cylinder body 132. This enables the protruding end 134A of the piston 134 and its connected top 134B to drive the contact block D12 to slide on the fixed rod 137, thereby changing its height position and raising it to the desired height. Figure 13A or Figure 15A The lifting position P12, or the protruding end 134A of the piston 134, can drive the contact block D12 to change its height position to reset or lower it as shown. Figure 13B or Figure 15B The origin point is located at P22.

[0127] In one embodiment, the lifting mechanism 100 includes a gasket 111 disposed on the contact block D12. The contact block D12 is secured to the gasket 111 by a bolt (not shown) passing through a through hole 111A.

[0128] Therefore, the lifting mechanism 100 can include two independent lifting modes: a fast lifting module G1 and a slow lifting module D1. The function of the slow lifting module D1 of this invention is to supplement the fast lifting module G1. It can accommodate gaps caused by the assembly of components or tolerances caused by measuring tools. Since the cylinder output can be adjusted according to the weight of the object being lifted, and by utilizing air pressure regulation control and the limited unlimited position function of the cylinder, the object being lifted can be lifted with the most appropriate force, so that the object being lifted can be completely pressed against the surface of another object.

[0129] In summary, this utility model measures the flatness of the raised floor during transmission, improves measurement accuracy, reduces and avoids errors or structural problems after assembly, and improves overall engineering efficiency.

[0130] Furthermore, the number of probes and sensors in this invention can be adjusted according to the actual size or requirements of the roof of the elevated floor being measured, so as to improve the accuracy of the measurement flatness.

[0131] In addition, this utility model uses a zero-point positioning block on the plate to fix and confirm the position of the measuring device and the four corners of the ceiling of the raised floor, so as to ensure the relative position of the probe and the ceiling.

[0132] In addition, during the transmission process, this utility model uses a positioning device to position the four sides of the raised floor to ensure the relative position of the raised floor and the measuring device, thereby ensuring the accuracy of subsequent measurements.

[0133] Furthermore, this utility model uses the lifting device of the raised floor to form a synchronous drive mechanism for the four lifting mechanisms to perform lifting actions synchronously, so that the raised floor can be raised or lowered to a predetermined position, thus avoiding the generation of positional differences in the upward movement of the four lifting mechanisms.

[0134] Furthermore, the lifting mechanism of this utility model has two independent fast lifting modules and slow lifting modules. In addition to being able to quickly raise the predetermined height through its fast lifting module, it can also compensate for fitting errors through air pressure regulation of the slow lifting module.

[0135] Although the present invention has been disclosed above by the above embodiments, it is not intended to limit the present invention. Any person skilled in the art should be able to make some modifications and refinements without departing from the spirit and scope of the present invention, but all such modifications and refinements shall fall within the protection scope of the present invention.
