The elevated floor elevating device 54 disclosed in the inventionis used to elevate the elevated floor 40. The elevated floor elevating device 54 includes four elevating mechanisms 100 and a driving motor GM wherein the elevating mechanisms 100 are used to carry and elevate the elevated floor 40. and the driving motor GM is used to drive the four elevating mechanisms 100 to move along the elevating direction LB so as to move the elevated floor 40 along the elevating direction LB.

It should be noted that the elevated floor 40 disclosed herein has a rectangular shape, and the size of the elevated floor 40 disclosed herein is, for example, 600 mm×600 mm×60 mm, and is made of materials such as aluminum alloy die-casting.

Since the four elevating mechanisms 100 are supported at four corners of the elevated floor 40 respectively, they can be elevated and lowered smoothly. In other embodiments, the four elevating mechanisms 100 can each have a driving mechanism that sets torque to achieve the purpose of synchronously elevating the four elevating mechanisms 100 to a predetermined position at the same time.

In one embodiment, the elevating device 54 of the elevated floor disclosed includes four elevating mechanisms 100, a driving motor GM, a belt 542, two first support plates 544 and two second support plates 545.

Both ends of the first support plate 544 are connected to the two second support plates 545 respectively, and a square frame is formed by connecting the two first support plates 544 and the two second support plates 545, and can synchronously performing ascending and descending linear motions making the screws G13 in the four elevating mechanisms 100 can synchronously drive the contact blocks D12 of the elevating device 54 of the elevated floor to synchronously contact the four corners of the elevated floor.

The driving motor GM is fixed between two of the elevating mechanisms 100. The belt 542 is wound around the transmission wheels 151 of the four elevating mechanisms 100 and the driving motor GM to constitute a synchronous driving mechanism. In this way, the driving motor GM can drive the belt 542 to rotate, and the belt 542 can drive the transmission wheel 151 of each elevating mechanism 100 so as to make the contact block D12 of each elevating mechanism 100 execute a elevating action. Since the four elevating mechanisms 100 are driven by the same driving source (driving motor GM) and transmission structure (belt 542) to synchronously execute elevating action making the contact block D12 can be elevated or lowered to a predetermined position, thereby it can avoid the generation of position difference in the elevating action of the four elevating mechanisms 100.

In one embodiment, the elevating mechanism 100 may include two independent elevating modes which are a fast elevating module G1, G2, G3, G4 and a slow elevating module D1, D2, D3, D4. In addition to the aforementioned synchronous execution of the elevating actions of the four elevating mechanisms 100, the heights of the four elevating mechanisms 100 can be synchronously and quickly raised by the fast elevating modules G1, G2, G3, G4. In addition, the slow elevating modules D1, D2, D3, D4 can be used to supplement the fast elevating modules G1, G2, G3, G4 to strengthen the fitness on the four corners of the elevated floor.

Please continue to refer to FIG. 6 and FIG. 7. The fast lifting modules G1, G2, G3, and G4 of each lifting mechanism 100 of the present disclosure are connected to the slow lifting modules D1, D2, D3, and D4. The fast lifting module G1 includes a T-nut connector G11, a connecting flange G12, and a screw G13. One end of the four screws G13 is respectively fixed to the two ends of the first support plate 544. The aforementioned belt 542 drives the transmission wheel 151 to rotate, so as to synchronously drive the transmission wheel connecting member 152 inside the transmission wheel 151 and the T-nut 153 (as shown in FIG. 4) connected thereto to rotate. At this time, since the first support plate 544 and the second support plate 545 at the bottom of the four screw rods G13 are fixed ends, the screw rods G13 cannot be rotated, and the transmission wheel 151 synchronously drives the transmission wheel connecting member 152 and the T-nut 153 connected thereto to rotate, and the T-nut 153 can drive the screw rod G13 to perform vertical linear motion, such as the lifting position P11 shown in FIG. 6, so as to drive the slow lifting modules D1, D2, D3, D4 and the contact block D12 connected thereto to raise their height position, thereby raising the height position of the elevated floor 40. The transmission wheel 151 synchronously drives the transmission wheel connector 152 and the connected T-nut 153 to rotate, and the T-nut 153 drives the screw G13 to move up and down linearly, and quickly drives the screw G13 to rise linearly, that is, the rotational motion of the T-nut 153 is converted into the linear motion of the screw G13, so as to quickly reach the purpose of rising position. In conjunction with the aforementioned method of simultaneously driving the four lifting mechanisms 100 through a single power source (driving motor GM), the elevated floor 40 is lifted synchronously and quickly to a predetermined height, and the position difference caused by the different rising positions of the four lifting mechanisms 100 can be avoided, thereby ensuring that the four corners of the elevated floor 40 can be smoothly lifted by the four lifting mechanisms 100, avoiding the height difference of the four corners of the elevated floor 40, and preventing the elevated floor 40 from slipping during the lifting process.

On the contrary, as shown in FIG. 7, the transmission wheel 151 can be used to synchronously drive the transmission wheel connector 152 and the T-type nut 153 connected thereto to rotate in the opposite direction making the protruded end 142 of the screw G13 and the connecting flange pivotally connected thereto reset to the origin position P21 as shown in FIG. 7 so as to drive the slow elevating modules D1, D2, D3, D4 and the contact block D12 connected thereto to be reset to their height positions.

In addition to the above-mentioned fast elevating modules G1, G2, G3, G4, the slow elevating modules D1, D2, D3, D4 disclosed in the invention include a cylinder power source D11, a contact block D12, and a T-shaped connector E1. Both ends of the T-shaped connector E1 are respectively connected and fixed to the upper connecting flange 162 and the cylinder power source D11 i.e. by the use of the T-shaped connector E1 is connected to the fast elevating module G1. The cylinder power source D11 is connected to the contact block D12, the gasket 111 is fixed on the contact block D12. The other end of the cylinder power source D11 is connected to the fast elevating modules G1, G2, G3, G4. The function of the slow elevating modules D1, D2, D3, D4 disclosed in the invention is to supplement the fast elevating modules G1, G2, G3, G4. The gaps between the components are formed by the thickness of the four corners of the elevated floor 40. Since the thickness tolerance generated during processing and the total error caused by various factors including but not limited to measuring tools make it impossible for the four corner surfaces of the elevated floor 40 to completely fit the fitting body. By the use of the controllability of the air pressure of the cylinder power source D11, the cylinder power source D11 drives the contact block D12 to move so as to adjust the height position of the elevated floor 40.

Since the cylinder output can be adjusted according to the weight of the elevated floor 40, and the air pressure is controlled by the air pressure regulation, and the limited cylinder's infinite function, the elevated floor 40 can be elevated with the most appropriate force so that the surfaces of the four corners of the elevated floor 40 are completely fit to the position of the object, so as to achieve the effectiveness and accuracy of flatness measurement.

To summarize the above description, the elevating mechanism in the invention has two independent fast elevating modules and slow elevating modules. In addition to being able to quicklyelevate to a predetermined height of the fast elevating module, it further can use the air pressure regulation of the slow elevating module to compensate for the fitting error.

Furthermore, through the elevating device of the elevated floor, the present disclosure has the disposed the four elevated mechanisms constitute a synchronized driving mechanism so as to execute synchronized action making the elevated floor can be elevated or lowered to a predetermined position, so that the elevated floor can thus avoid the problem generated by the rising action position difference of the four elevating mechanisms.
