Description

Technical Field

[0001] The present invention relates to a lifting mechanism and a lifting device, and particularly to a lifting mechanism and a lifting device for a raised floor.

Background Art

[0002] A raised floor is a floor system widely used in semiconductor factories, offices, computer rooms, etc., and is basically composed of a support frame and a plurality of floor panels with adjustable height. These floor panels are raised from the ground to form a space for arranging equipment such as electric wires, cables, pipes, etc., and can assist in improving ventilation and heat dissipation.

[0003] The lifting of the raised floor can be used for measurement, processing or related operations. Due to the position difference caused by the difference in the lifting operation position of the raised floor, the lifting of the raised floor becomes unstable, a difference occurs in the height of the four corners of the raised floor, and furthermore, the raised floor may slip down during the lifting process.

[0004] Furthermore, conventional lifting mechanisms only provide a lifting function and do not have a function of finely adjusting the lifting in consideration of the tolerances of joining and measuring tools, and cannot guarantee that the workpiece to be joined is completely joined or close to the joining object.

[0029] The terms "includes," "equipped with," and "possess" used in this invention are all open terms, meaning that they "include but are not limiting."

[0030] In the description of each embodiment, when a component is described using terms such as "first," "second," "third," and "fourth," these terms are used solely to distinguish the components from one another and do not restrict the order or importance of these components.

[0031] In the description of each embodiment, the so-called "combination" or "connection" may refer to two or more elements making direct physical or electrical contact with each other, or indirect physical or electrical contact with each other, and may also refer to two or more elements operating or acting with each other.

In other embodiments, the so-called "module" may also refer to a combination of a hardware module and a software module, meaning that the "module" may include a software program in addition to the hardware component.

[0033] In the description of each embodiment, the so-called "Fast Lifting Module" is generally defined as a mechanical module designed to perform lifting operations quickly and efficiently. Because this type of fast lifting module can complete lifting motions in a shorter time compared to general lifting systems, it is typically used in applications where lifting or repositioning of objects is required in a short amount of time.

[0034] In the description of each embodiment, the so-called "Slow Lifting Module" is a mechanical module designed to perform slower and more stable lifting operations. This type of module is typically used in applications where there are specific requirements for lifting speed, particularly when more precise control is needed or when it is necessary to protect objects from impact.

[0035] In the description of each embodiment, the term "T-shape" refers to a structure or shape resembling the letter "T". A T-shaped structure consists of two parts: a vertically elongated strip (called the main body or beam) and a horizontal section (called the crossbar or crossbeam) connected perpendicularly to it. This shape, being "T" shaped, is often used in support frames or connecting members because it can provide greater structural stability.

[0036] In the description of each embodiment, the so-called "drive wheel" is a wheel used to transmit power and motion in a mechanical system, which can transmit power to other components via friction, gears, or belts to enable the operation of a mechanical device.

[0037] In the description of each embodiment, the so-called "connecting flange" is a mechanical element used to connect two members. Connecting flanges are usually made up of circular or polygonal metal plates (flanges), and the two flanges are fixed together with bolts, screws, welds, etc., to achieve a structural connection.

[0038] In the description of each embodiment, the so-called "cylinder power source" refers to a device that drives piston motion using a pneumatic or hydraulic system. Cylinders are typically power conversion elements in mechanical systems, converting the energy of compressed gas or liquid into linear motion.

Figure 2 is an explanatory diagram of one embodiment of the origin position of the lifting mechanism according to the present invention.

Figure 5 is a cross-sectional view of one embodiment of the origin position of the lifting mechanism according to the present invention. Refer to Figures 1 to 5. The lifting mechanism 100 includes a high-speed lifting module G1, a low-speed lifting module D1, and a T-type connector E1, and the lifting mechanism 100 includes two independent lifting modes, the high-speed lifting module G1 and the low-speed lifting module D1, the high-speed lifting module G1 can be quickly raised to a predetermined height, the low-speed lifting module D1 is fixed above the high-speed lifting module G1, and the low-speed lifting module D1 and the high-speed lifting module G1 lift up and down synchronously. The high-speed lifting module G1 includes a T-type nut connector G11, a connecting flange G12, and a screw G13, while the low-speed lifting module D1 includes a cylinder power source D11 and a contact block D12.

[0040] The T-type nut connector G11 includes a transmission wheel 151, a transmission wheel connector 152, a T-type nut 153, a bearing seat 154, at least one bearing 155, a nut 156, a retaining structure 157, a C-type mating ring 158, and two deep groove bearings 159. The number of bearings 155 can be adjusted according to the structural arrangement.

[0041] A transmission wheel connector 152 is installed inside the transmission wheel 151, and one side of a T-nut 153 is connected to the transmission wheel connector 152. The T-nut 153 is fixed together with the transmission wheel 151 by the transmission wheel connector 152 and can rotate synchronously.

[0042] In one embodiment, a T-shaped nut 153 is housed within a bearing seat 154. The T-shaped nut 153 has a long through-hole, and its upper end has a male thread. The lower end of the T-shaped nut 153 is connected to and fixed with the transmission wheel 151, allowing them to rotate as a single unit. For example, when assembling the T-shaped nut connector G11, first the shaft portion of the transmission wheel connector 152 is fitted into the central hole of the transmission wheel 151, and the shaft portion of the T-shaped nut 153 is fitted upward into the central hole of the bearing seat 154. Then, at least one fixing screw SC is used to pass through the through-hole H1 of the transmission wheel 151, the through-hole H2 of the transmission wheel connector 152, and the through-hole H3 of the T-shaped nut 153 in sequence, thereby fixing the transmission wheel 151, transmission wheel connector 152, and T-shaped nut 153 as a single unit, and connecting and fixing the transmission wheel 151 and the T-shaped nut 153 as a single unit.

[0043] The bearing 155 is housed within the bearing seat 154, and the bearing 155 is positioned between the T-nut 153 and the bearing seat 154. The nut 156 is fixed to the outer teeth of the upper end of the T-nut 153, fixing the position of the bearing 155.

[0044] The C-shaped fitting ring 158, the two deep groove bearings 159, and the retaining structure 157 are positioned on the outer circumference of the T-shaped nut 153, and the deep groove bearings 159 are positioned at the upper and lower ends of the retaining structure 157, with the retaining structure 157 fixing the positions of the two deep groove bearings 159. The C-shaped fitting ring (C-Ring Clip) 158, also called an elastic fitting ring (Circlip) or retaining ring, is an elastic fastener used to fix a part or bearing to a shaft or hole. It usually has a C-shaped or nearly circular structure with openings at both ends, and after installation, it can firmly fix the part in place by elastic force. Taking this embodiment as an example, the C-shaped fitting ring 158 is positioned between one deep groove bearing 159 and bearing 155, reinforcing and fixing the position of bearing 155.

[0045] The Deep Groove Ball Bearing 159 is a roller bearing characterized by having deep, arc-shaped grooves in the raceways of its inner and outer rings, allowing it to withstand radial loads and a constant axial load.

[0046] The connecting flange G12 includes a lower connecting flange 161 and an upper connecting flange 162 connected to the lower connecting flange 161, the upper connecting flange 162 being installed above the lower connecting flange 161. In one embodiment, bolts (not shown) are used to fasten the upper connecting flange 162 and the lower connecting flange 161 together through a through hole H4.

[0047] The upper end of screw G13 is fixed to the lower connecting flange 161, and the lower end of screw G13 passes through the nut 156, T-nut 153, bearing 155, transmission wheel connector 152, and transmission wheel 151 in that order. The first bolt 145 and bolt head 146 are installed above the T-nut connector G11. In one embodiment, the screw G13 includes an extended end 142, the T-type connector E1 is installed above the extended end 142, the extended end 142 is the upper end of the screw G13, the upper end of the screw G13 is connected to and fixed to the lower end of the first bolt 145, the upper end of the first bolt 145 is the bolt head 146, the first bolt 145 is inserted into the countersink hole 161A of the lower connecting flange 161 and fixed to the screw hole at the upper end of the screw G13, thereby fixing the screw G13 and the lower connecting flange 161 together, and the bolt head 146 is fixedly connected to the countersink hole 161A of the lower connecting flange 161. As can be seen from this, the first bolt 145 is fixed to the lower connecting flange 161 using the bolt head 146 at the upper end of the first bolt 145, and the extended 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 may be integrally molded with the bolt, and other fixing members may be used to replace the first bolt 145 and its bolt head 146. In this invention, the first bolt 145 is used for fixing.

[0048] In one embodiment, as shown in Figure 3B, a countersunk hole 161A is provided within the lower connecting flange 161, and 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 and has a single conical expansion hole at its opening for accommodating the head of a countersunk screw (such as the first bolt 145). The head of the first bolt 145 can be flush with the surface of the lower connecting flange 161 or slightly lower than the surface. The design of the countersunk hole 161A mainly emphasizes aesthetics and functionality. For example, the head of the first bolt 145 does not protrude and affect the flatness and aesthetics of the lower connecting flange 161. The lower connecting flange 161, with its flattened upper surface, can be coupled and fixed with the upper connecting flange 162.

[0049] The screw G13 is sequentially provided with a nut 156, a T-type nut 153, and a transmission wheel connector 152 on the transmission wheel 151. The aforementioned T-type nut connector G11, connecting flange G12, and screw G13 constitute the high-speed lifting module G1. The low-speed lifting module D1 includes a cylinder power source D11 and a contact block D12, the contact block D12 being connected to the cylinder power source D11.

[0050] One end of the T-type connector E1 is connected to the upper connecting flange 162, and the other end of the T-type connector E1 is provided with a fixing base 148. The upper connecting flange 162 and the fixing base 148 at both ends of the T-type connector E1 are connected and fixed to the high-speed lifting module G1 and the low-speed lifting module D1, respectively. In other words, one end of the T-type connector E1 is connected and fixed to the high-speed lifting module G1 via the upper connecting flange 162, and the other end of the T-type connector E1 is connected and fixed to the low-speed lifting module D1 via the fixing base 148.

[0051] One end of the T-type connector E1 is mounted on the fixed base 148, and the other end of the T-type connector E1 is connected to the upper connecting flange 162. The second bolt 143 is connected to the fixed base 148, and the upper end of the T-type connector E1 is the fixed base 148. The lower end of the T-type connector E1 is the upper connecting flange 162, and the upper end of the T-type connector E1 is connected and fixed to the bottom of the cylinder power source D11 via the second bolt 143 and the fixed base 148. The method of fixing the second bolt 143 and the aforementioned first bolt 145 is the same; that is, the fixed base 148 of the T-type connector E1 is passed through the bottom of the cylinder power source D11 using the second bolt 143 and fixed to the screw hole of the fixed base 148, thereby connecting and fixing the cylinder power source D11 to the fixed base 148. As can be seen from this, the bottom of the cylinder power source D11 is connected and fixed to the fixing base 148 at the upper end of the T-type connector E1 via the second bolt 143, and the upper connecting flanges 162 and fixing bases 148 at both ends of the T-type connector E1 are connected and fixed to the high-speed lifting module G1 and the low-speed lifting module D1, respectively. The second bolt 143 may be replaced with other fixing members, but the present invention employs the second bolt 143 for fixing.

[0052] The rotation of the transmission wheel 151 is driven, causing the transmission wheel connector 152 inside the transmission wheel 151 and the T-shaped nut 153 connected thereto to rotate synchronously. The T-shaped nut 153 is fixed to the transmission wheel 151, and as the T-shaped nut 153 rotates, the screw hole 149 at the bottom end of the screw G13 can be fixed to both ends of the first support plate 544 using screws (not shown) (as shown in Figures 6 to 8), fixing the bottom end of the screw G13 as a fixed end and preventing the screw G13 from rotating. The T-shaped nut 153 drives the screw G13 to move up and down linearly. The up and down linear motion (or vertical motion) of the screw G13 refers to the movement of the screw G13 along a straight line in the vertical direction. The direction of motion of the screw G13 is up and down, and the motion is along a straight line, driving the low-speed lifting module D1 and the contact block D12 connected thereto to raise its height position, as shown in the lifting position P11 in Figure 1 or Figure 4. The transmission wheel 151 rotates the transmission wheel connector 152 and the T-shaped nut 153 connected thereto, quickly driving the linear upward movement of the screw G13, that is, converting rotational motion into linear motion and quickly reaching the raised position.

[0053] Conversely, as shown in Figure 2 or Figure 5, the transmission wheel 151 can rotate in the opposite direction to the transmission wheel connector 152 and the T-shaped nut 153 connected thereto, returning the extended end 142 of the screw G13 and the connecting flange G12 pivotally attached thereto to the origin position P21 as shown in Figure 2 or Figure 4, and returning or lowering the low-speed lifting module D1 and the contact block D12 connected thereto to their height position.

[0054] The cylinder power source D11 includes a cylinder body 132, a piston 134, at least one through hole 135, at least one air intake / exhaust hole 136, and a plurality of fixed rods 137. The piston 134 can move within the cylinder body 132 and includes a protruding end 134A and an upper part 134B. The protruding end 134A is connected to the upper part 134B, which is connected and fixed to the bottom of the contact block D12. The cylinder power source D11 can raise and lower the contact block D12 at a low speed to adjust its height. 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 upper part 134B. The piston 134 is able to lift the contact block D12 evenly and in a balanced manner using the plurality of fixed rods 137, causing it to move up and down at a low speed, and the fixed rods 137 can be linked to the contact block D12.

[0055] In one embodiment, the cylinder body 132 is fixed to the bottom of the cylinder body 132 by passing through a through hole 135 using bolts (not shown), and at least one air intake / exhaust hole 136 is provided in the cylinder body 132.

[0056] The aforementioned cylinder power source D11, contact block D12, and T-type connector E1 constitute a low-speed lifting module D1. By utilizing the pneumatic controllability of the cylinder power source D11, the cylinder power source D11 moves the contact block D12, allowing the piston 134 to move within the cylinder body 132. As a result, the protruding end 134A of the piston 134 and the upper part 134B connected thereto slide the contact block D12 on the fixed rod 137, changing its height position to raise it to the lifting position P12 as shown in Figure 1 or Figure 4, or the protruding end 134A of the piston 134 drives the contact block D12, changing its height position to return it to or lower it to the origin position P22 as shown in Figure 2 or Figure 5.

[0057] In one embodiment, the lifting mechanism 100 includes a gasket 111, which is mounted on a contact block D12. The contact block D12 is secured to the gasket 111 by bolts (not shown) passing through holes 111A.

[0058] As can be seen from this, the lifting mechanism 100 includes two independent lifting modes: a high-speed lifting module G1 and a low-speed lifting module D1. The function of the low-speed lifting module D1 of the present invention complements the high-speed lifting module G1 and can accommodate gaps in combinations between members or tolerances of measuring tools. The cylinder output uses pneumatic adjustment control according to the weight of the object being lifted, and the cylinder has no finite position restriction function, allowing the object to be lifted with the most appropriate force and to be perfectly joined to the surface of another object.

[0059] Figure 6 is a perspective view of one embodiment of the lifting device for a raised floor according to the present invention. Figure 7 is an explanatory diagram of one embodiment of the lifting position of the lifting device for a raised floor according to the present invention. Figure 8 is an explanatory diagram of one embodiment of the origin position of the lifting device for a raised floor according to the present invention. Referring to Figures 6 to 8, the lifting modules G2, G3, G4 and the low-speed lifting modules D2, D3, D4 shown in Figures 6 to 8 have the same configuration as the high-speed lifting module G1 and the low-speed lifting module D1 shown in Figures 1 to 5.

[0060] The lifting position P1 of the lifting mechanism 100 in Figures 1 and 4 can correspond to the lifting position P1 of the lifting mechanism 100 in Figure 7, and the lifting position P1 includes the lifting positions P11 of the high-speed lifting modules G1, G2, G3, and G4 and the lifting positions P12 of the low-speed lifting modules D1, D2, D3, and D4. The origin position P2 in Figures 2 and 5 corresponds to the lifting mechanism 100 in Figure 8, and the origin position P2 includes the origin positions P21 of the high-speed lifting modules G1, G2, G3, and G4 and the origin positions P22 of the low-speed lifting modules D1, D2, D3, and D4.

[0061] The floor lifting device 54 of the present invention is used to raise and lower the floor 40. The floor lifting device 54 includes four lifting mechanisms 100 and a drive motor GM. The lifting mechanisms 100 are used to place and raise the floor 40, and the drive motor GM is used to move the four lifting mechanisms 100 along the lifting direction LB and to move the floor 40 along the lifting direction LB.

[0062] Furthermore, the raised floor 40 of the present invention has a rectangular shape, and its dimensions are, for example, 600 mm × 600 mm × 60 mm, and it is made of a material such as aluminum alloy die-cast.

[0063] These four lifting mechanisms 100 each support one of the four corners of the raised floor 40 and can be raised and lowered smoothly. In another embodiment, the drive mechanism of each of the four lifting mechanisms 100 can achieve the objective of synchronously lifting the four lifting mechanisms 100 to a predetermined position by setting the torque.

[0064] In one embodiment, the floor lifting device 54 of the present invention includes four lifting mechanisms 100, a drive motor GM, a belt 542, two first support plates 544, and two second support plates 545. The ends of the two first support plates 544 are each connected to the two second support plates 545, and the connection of the two first support plates 544 and the two second support plates 545 forms a rectangular frame, which performs linear lifting motion in synchronization with four screws G13, and the contact block D12 of the floor lifting device 54 is driven in synchronization with the screws G13 of the four lifting mechanisms 100, and contacts the four corners of the floor in synchronization.

[0065] The drive motor GM is fixed between the two lifting mechanisms 100. The belt 542 is wrapped around the drive motor GM and the transmission wheels 151 of the four lifting mechanisms 100, forming a synchronous drive mechanism. In this way, the drive motor GM drives the rotation of the belt 542, which in turn drives the transmission wheels 151 of the four lifting mechanisms 100, enabling the contact blocks D12 of the four lifting mechanisms 100 to perform lifting movements. Since the four lifting mechanisms 100 are driven by the same drive source (drive motor GM) and transmission structure (belt 542), they can perform lifting movements synchronously, raising and lowering the contact blocks D12 to predetermined positions and avoiding positional differences in the lifting movements of the four lifting mechanisms 100.

[0066] In one embodiment, the lifting mechanism 100 may include two independent lifting modes: high-speed lifting modules G1, G2, G3, G4 and low-speed lifting modules D1, D2, D3, D4. In addition to the synchronous execution of the lifting operations of the four lifting mechanisms 100 described above, the high-speed lifting modules G1, G2, G3, G4 allow the heights of the four lifting mechanisms 100 to be raised synchronously and quickly. Furthermore, by supplementing the high-speed lifting modules G1, G2, G3, G4 with the low-speed lifting modules D1, D2, D3, D4, the adhesion to the four corners of the raised floor can be enhanced.

[0067] Continuing with reference to Figures 6 and 7, the high-speed lifting modules G1, G2, G3, and G4 of each lifting mechanism 100 of the present invention are connected to the low-speed lifting modules D1, D2, D3, and D4. The high-speed lifting module G1 includes a T-nut connector G11, a connecting flange G12, and screws G13, with one end of each of these four screws G13 fixed to both ends of the first support plate 544. The aforementioned belt 542 drives the rotation of the transmission wheel 151, thereby synchronously rotating the transmission wheel connector 152 within the transmission wheel 151 and the T-nut 153 connected thereto (as shown in Figure 4). 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 rotate, and the transmission wheel 151 rotates the transmission wheel connector 152 and the T-shaped nut 153 connected thereto in synchronous motion. The T-shaped nut 153 drives the screws G13 to perform vertical linear motion, and the lifting position P11 shown in Figure 6 drives the low-speed lifting modules D1, D2, D3, D4 and the contact block D12 connected thereto to raise their height positions, and further raises the height position of the raised floor 40. The transmission wheel 151 rotates the transmission wheel connector 152 and the T-shaped nut 153 connected thereto in synchronous motion, and the T-shaped nut 153 drives the screws G13 to perform vertical linear motion, quickly driving the linear upward movement of the screws G13, that is, converting the rotational motion of the T-shaped nut 153 into the linear motion of the screws G13, and quickly achieving the objective of raising the position. By combining the aforementioned method of simultaneously driving the four lifting mechanisms 100 with a single power source (drive motor GM), the raised floor 40 can be quickly raised to a predetermined height in synchronous motion, avoiding positional differences due to differences in the lifting positions of the four lifting mechanisms 100, and the four corners of the raised floor 40 can be stably raised by the four lifting mechanisms 100, avoiding differences in the height of the four corners of the raised floor 40 and preventing the raised floor 40 from sliding down during the lifting process.

[0068] Conversely, as shown in Figure 7, the aforementioned transmission wheel 151 can be used to synchronously drive the transmission wheel connector 152 and the T-shaped nut 153 connected thereto to rotate in opposite directions, returning the extended end 142 of the screw G13 and the connecting flange G12 connected thereto to the origin position P21 shown in Figure 7, and returning the low-speed lifting modules D1, D2, D3, D4 and the contact block D12 connected thereto to their respective height positions.

[0069] In addition to the high-speed lifting modules G1, G2, G3, and G4 described above, the low-speed lifting modules D1, D2, D3, and D4 of the present invention include a cylinder power source D11, a contact block 12, and a T-type connector E1. Both ends of the T-type connector E1 are connected and fixed to the upper connecting flange 162 and the cylinder power source D11, i.e., connected to the high-speed lifting module G1 by the T-type connector E1. The cylinder power source D11 is connected to the contact block D12, the gasket 111 is fixed to the contact block D12, and the other end of the cylinder power source D11 is connected to the high-speed lifting modules G1, G2, G3, and G4. The function of the low-speed lifting modules D1, D2, D3, and D4 of the present invention is to complement the high-speed lifting modules G1, G2, G3, and G4, as the four corner surfaces of the raised floor 40 cannot be perfectly joined to the joining object due to various factors such as gaps in the combination of members, tolerances during processing of the thickness of the four corners of the raised floor 40, and total errors caused by measuring tools. By utilizing the pneumatic controllability of the cylinder power source D11, the cylinder power source D11 moves the contact block D12 to adjust the height position of the raised floor 40.

[0070] The cylinder output utilizes pneumatic adjustment control according to the weight of the raised platform 40 and a finite position-unrestricted function of the cylinder, enabling the raised platform 40 to be lifted with the most appropriate force, perfectly joining the four corner surfaces of the raised platform 40 to the position of the joining object, and achieving the effectiveness and accuracy of the flatness measurement.

[0071] In summary, the lifting mechanism of the present invention has two independent high-speed lifting modules and low-speed lifting modules. In addition to the high-speed lifting module being able to lift a predetermined height at high speed, the low-speed lifting module can correct joint errors by adjusting the air pressure.

[0072] Furthermore, the present invention configures the four lifting mechanisms installed on the raised floor as a synchronous activation mechanism using a floor lifting device, allowing them to perform the lifting and lowering operations synchronously, raising and lowering the raised floor to a predetermined position, and avoiding positional differences in the upward movement of the four lifting mechanisms.

[0073] Although the present invention has been disclosed by embodiments as described above, this does not limit the invention, and those skilled in the art can make some modifications and alterations without departing from the spirit and scope of the invention. Therefore, the scope of protection of the present invention shall be based on the claims defined below. [Explanation of Symbols]
