Detailed Description
The invention will be further described with reference to the accompanying drawings.
As shown in fig. 1-9, according to a first aspect of the present invention, the present invention provides a stabilization apparatus 200 for a tower plant for maintaining normal and stable operation of the tower plant. Wherein the tower device may be, for example, a 3D printer 100.
The following describes the 3D printer 100 as an example.
As shown in fig. 1, the 3D printer 100 generally includes a column 140, and first and second arms 110 and 120 disposed at both sides of the column 140, respectively, each of the first and second arms 110 and 120 being rotatable along an axis of the column 140. Further, the 3D printer 100 further includes a 3D print head 130 for executing a print job, which is movably provided on the rotatable first arm 110.
Since the first arm 110 is connected to the column 140 to form a cantilever, a stable operation of the first arm 110 must be ensured to uniformly discharge the discharge end of the 3D printhead 130, so that the printing material flowing out of the discharge end can be formed in a layer-by-layer stacked manner in a desired building form. The stabilizing device 200 of the present invention can ensure the stable operation of the first arm 110.
Specifically, as shown in fig. 1 and 2, the stabilization device 200 of the present invention includes an adjustable bracket 210 and an adjustable rail 220 positioned on the ground. Wherein a first end (e.g., an upper end) of the adjustable bracket 210 is coupled to the first arm 110 and a second end (e.g., a lower end) of the adjustable bracket 210 is coupled to the adjustable rail 220 such that the adjustable bracket 210 can move on the adjustable rail 220 as the first arm 110 rotates.
Since the adjustable rail 220 is located on the ground, the adjustable bracket 210 can support the first arm 110 such that the first arm 110 no longer operates in a cantilever manner, thereby ensuring the stability of its operation.
Further, by adjusting the height of the adjustable bracket 210 and/or the height of the adjustable rail 220, the second end of the adjustable bracket is positioned in the same horizontal plane as the discharge end of the 3D printhead 130. As described above, the 3D printhead 130 prints in a layer-by-layer manner, so that after printing one layer of the structure 300 (as shown in fig. 8), the height of the 3D printhead 130 from the ground is increased by a distance (i.e. the height of "one layer of the structure") to start printing the next layer of the structure 300. Thus, by continuously increasing the ground clearance of the 3D printhead 130, the printed structures 300 are layered, so that a desired building shape can be formed. To accommodate the increasing height of the 3D printhead 130, the height of the adjustable bracket 210 and the height of the adjustable rail 220 may be adjusted.
For example, as the elevation of the 3D printhead 130 increases, the adjustable bracket 210 is extended to ensure that the second end of the adjustable bracket 210 is always in contact with the adjustable rail 220, thereby providing support for the first arm 110. Or as the elevation of the 3D printhead 130 increases, the elevation of the adjustable rail 220 increases, it is also ensured that the second end of the adjustable bracket 210 is always in contact with the adjustable rail 220, thereby providing support for the first arm 110. It will be appreciated that contact between the adjustable bracket 210 and the adjustable rail 220 may also be ensured by extending the two and increasing the height of the adjustable rail.
In addition, when the 3D print head 130 forms a certain layer of the structure 300, the first arm 110 drives the 3D print head 130 to rotate around the upright 140, and the 3D print head 130 moves on the first arm 110 as required, so that the structure 300 conforms to the contour of the building. Therefore, when the first arm 110 rotates, the adjustable bracket 210 is also driven to rotate, and the second end of the adjustable bracket 210 is provided with the walking device 230 to ensure that the first arm 110 can still be stably supported during the rotation process.
Specifically, running gear 230 includes a drop-off prevention roller 231 disposed on adjustable track 220 and a connecting frame 232. One end of the connection frame 232 is connected with the anti-drop roller 231, and the other end is rotatably connected with the second end of the adjustable bracket 210, so that the running track of the anti-drop roller 231 conforms to the shape of the adjustable rail 220.
As shown in fig. 3a, the link 232 includes a support plate 2321 and a link post 2322 disposed on the support plate 2321, and the link post 2322 is rotatably connected to the second end of the adjustable bracket 210 through a bearing 238, so that when the anti-falling roller 231 walks on the adjustable track 220, the angle of the anti-falling roller 231 can be flexibly adjusted (for example, 360-degree rotation can be performed), and thus the walking track of the anti-falling roller 231 conforms to the shape of the adjustable track 220.
As shown in fig. 3a and 4, the escape prevention roller 231 includes a pressure wheel 233 and an escape prevention wheel 234. The pressure wheel 233 is used to travel on the adjustable track 220, and the pressure wheel 233 is rotatably connected to a pressure wheel baffle 235 below the link 232. The anti-drop wheel 234 is used for preventing the pressure wheel 233 from being separated from the adjustable rail 220, and the anti-drop wheel 234 is located in a recess of the adjustable rail 220 and is connected with a baffle plate of the pressure wheel 233.
As shown in fig. 3a, the pressure wheel barrier 235 includes a first barrier 236 and a second barrier 237 respectively located at left and right sides below the link 232, wherein the first barrier 236 has a longer length and the second barrier 237 has a shorter length, which covers the pressure wheel 233 only in a radial direction. The pressure wheel 233 is rotatably disposed between the first bezel 236 and the second bezel 237. The drop-off preventing wheel 234 is connected to the first baffle 236 and is located below the pressure wheel 233, and the drop-off preventing wheel 234 is disposed in the recess 221 of the adjustable rail 220, so that when the pressure wheel 233 has a tendency to float upward with the upper surface of the adjustable rail 220 being separated from the upper surface of the adjustable rail 220 by the first arm 110, the drop-off preventing wheel 234 is caught in the recess 221 of the adjustable rail 220, preventing the pressure wheel 233 from being separated from the adjustable rail 220, thereby preventing the first arm 110 from floating upward; conversely, when first arm 110 has a tendency to float downward, it will move pressure wheel 233 downward, so that adjustable rail 220 supports pressure wheel 233, thereby preventing first arm 110 from floating downward, and thus ensuring the balance of first arm 110 and second arm 120 on the left and right sides of upright 140, so as to reduce the force applied to upright 140 by tilting to one side.
As can be seen from the above, the walking device 230 of the present invention can move the adjustable bracket 210 along with the rotation of the first arm 110, and can prevent the first arm 110 from floating up and down, so as to stabilize the first arm 110 during the rotation of the first arm 110.
It will be appreciated that as shown in fig. 5, the first arm 110 has a first rail 150,3D on which the print head 130 is disposed, and moves on the first rail 150.
The stabilization device 200 of the present invention also includes a sensing device 240 and a movable weight 250. The sensing device 240 is disposed on the connecting frame 232, and the sensing device 240 is used for detecting a compressive force or a tensile force applied to the adjustable bracket 210 when the 3D printhead 130 moves on the first arm 110.
Because the conventional track and running gear are generally in a linear configuration, and the rotation track of the first arm 110 of the present invention is circular, the action resistance forms an unstable factor when the adjustable bracket 210 is driven to run; furthermore, as the 3D printhead 130 moves over the first arm 110 or the printing material in the 3D printhead 130 changes, the first arm 110 may exert different forces on the adjustable bracket 210, thereby risking an imbalance between the first arm 110 and the second arm 120. For example, when the 3D printhead 130 moves toward the front end on the first arm 110, or when the printing material in the 3D printhead 130 increases (loads), the first arm 110 may generate pressure on the adjustable bracket 210; the first arm 110 may exert a pulling force on the adjustable bracket 210 as the 3D printhead 130 moves back on the first arm 110, or as the printed material in the 3D printhead 130 increases and decreases (discharges).
The sensing device 240 and the movable weight 250 of the present invention can solve the above two problems, namely, can reduce instability caused by movement resistance and ensure the balance of the first arm 110 and the second arm 120.
As shown in fig. 1, the movable weight 250 is disposed on the second arm 120 of the 3D printer 100, the movable weight 250 is connected to the sensing device 240 on the connecting frame 232, and the movable weight 250 moves toward the 3D printhead 130 or away from the 3D printhead 130 according to the pressure or the tensile force detected by the sensing device 240, so that the first arm 110 and the second arm 120 maintain balance.
Specifically, as shown in fig. 3a, 3b and 4, the sensing device 240 includes a spring 241 and a contact switch 242. The spring 241 is disposed on the outer wall of the connection post 2322 of the connection frame 232, and the upper end of the connection post 2322 extends into the adjustable bracket 210 from the lower end of the adjustable bracket 210, and the two are relatively slidable. As shown in fig. 3a and 3b, a clamping table 2323 is disposed at an upper end of the connection post 2322, the clamping table 2323 is disposed inside the adjustable bracket 210, and as shown in fig. 3b, the clamping table 2323 and a part of an upper end of the connection post 2322 are shown by dotted lines.
The radial dimension of the catch 2323 is greater than the lower radial dimension of the adjustable bracket 210 and less than the inner radial structure of the adjustable bracket 210, and therefore, the catch 2323 can move inside the adjustable bracket 210 without escaping from the bottom of the adjustable bracket 210. And when the adjustable bracket 210 moves up to the first limit position relative to the connection post 2322, the clamping table 2323 clamps the bottom end of the adjustable bracket 210 with the connection post 2322, so that the adjustable bracket 210 can drive the connection post 2322 to move together.
The lower end of the adjustable bracket 210 is connected with a pressing plate 2324, and the pressing plate 2324 is contacted with the upper end of the spring 241. As the 3D printhead 130 moves on the first arm 110 in a direction toward the adjustable bracket 210, the weight of the front end of the first arm 110 increases, which has a tendency to float downward, the adjustable bracket 210 receives its pressure and transfers the pressure to the platen 2324, so that the platen 2324 may compress the springs 241.
Conversely, when the 3D printhead 130 moves on the first arm 110 in a direction away from the adjustable bracket 210, the weight of the front end of the first arm 110 decreases, which has a tendency to float upward, and the adjustable bracket 210 receives its pulling force, thereby driving the platen 2324 to move upward, and the spring 241 is reset. And when the adjustable bracket 210 continues to move upwards, the clamping table 2323 clamps the bottom end of the adjustable bracket 210 with the connection post 2322, so that the adjustable bracket 210 drives the connection post 2322, the pressure wheel baffle 235, the first baffle 236 and the anti-drop wheel 234 to move upwards together.
The contact switch 242 is disposed on the connection post 2322 of the connection frame 232, the contact switch 242 is in signal connection with the movable counterweight 250, when the adjustable bracket 210 moves to the limit position, the contact switch 242 outputs corresponding signals, and the movable counterweight 250 moves in a direction away from the 3D print head 130 or a direction close to the 3D print head 130 according to the signals output by the contact switch 242.
Specifically, the contact switch 242 includes a first contact switch 244 and a second contact switch 245. As shown in fig. 3a, a first contact switch 244 is connected to the link 232, and in particular, the first contact switch 244 is disposed on the platen 2324, and the first contact switch 244 is in signal connection with the movable counterweight 250. When the adjustable bracket 210 moves downward, the pressure plate 2324 is driven downward, thereby compressing the spring 241. At the same time, the pressing plate 2324 also moves the first contact switch 244 downward, and the lower end of the first contact switch 244 may contact the support plate 2321. When the first arm 110 moves downward to the first limit position, the spring 241 is compressed to the limit position (indicating that the pressure applied to the adjustable bracket 210 has reached its limit value), the lower end of the first contact switch 244 contacts the support plate 2321, so that the first contact switch 244 is closed, and a signal is output, and the movable weight 250 moves in a direction away from the 3D printhead 130 according to the signal output by the first contact switch 244.
The second contact switch 245 is connected to the connection frame 232, specifically, the second contact switch 245 is disposed on the first shutter 236, and an upper end of the second contact switch 245 is located inside the adjustable rail 220. As shown in fig. 3a, the upper end of the second contact switch 245 is located at the lower side of the inner wall 2221 of the frame structure 222. The second contact switch 245 is also in signal connection with the movable weight 250. When the adjustable bracket 210 moves upward and drives the connection post 2322, the pressure wheel baffle 235, the first baffle 236 and the anti-drop wheel 234 to move upward together, the first baffle 236 drives the second contact switch 245 to move upward, and then the upper end of the second contact switch 245 can be in contact with the inner wall of the frame structure 222. When the first arm 110 moves up to the second limit position, the anti-drop wheel 234 moves to contact with the inner wall 2221 of the frame structure 222 (at this time, the tensile force applied by the adjustable bracket 210 is indicated to reach the limit value), the upper end of the second contact switch 245 contacts with the inner wall 2221, the second contact switch 245 is closed, a signal is output, and the movable balance block 250 moves towards the direction approaching the 3D print head 130 according to the signal output by the second contact switch 245.
The movable weight 250 is movable on the second arm 120 by a motor (not shown) in signal communication with the first contact switch 244 and the second contact switch 245, respectively. The motor drives the movable weight 250 to move according to the signals sent by the two contact switches.
Specifically, when the signal output by the first contact switch 244 meets the predetermined requirement, the pressure applied to the adjustable bracket 210 reaches its limit value, so that the motor drives the movable weight 250 to move away from the adjustable bracket 210, thereby increasing the weight of the rear end to counteract the tendency of the first arm 110 to float down, and thus maintain the balance of the first arm 110 and the second arm 120.
Conversely, when the signal output by the second contact switch 245 meets the predetermined requirement, it indicates that the tension applied to the adjustable bracket 210 has reached its limit value, so that the motor drives the movable weight 250 to move toward the adjustable bracket 210, thereby reducing the weight of the rear end to counteract the tendency of the first arm 110 to float, and thus maintain the balance of the first arm 110 and the second arm 120.
Further, as shown in fig. 5 and 8, the second arm 120 is provided with a second slide rail 160, and the movable weight 250 is provided on the second slide rail 160 and movable thereon.
As shown in fig. 5, the 3D printhead 130 is in a B segment on the first arm 110 (approximately in the middle portion of the first arm 110), and the movable weight 250 is in an E segment on the second arm 120 (approximately in the middle portion of the second arm 120), so that the first arm 110 and the second arm 120 are in a balanced state, and the first arm 110 is maintained in a stable operating state by the supporting action of the adjustable bracket 210 and the adjustable rail 220.
As shown in fig. 6, when the 3D printhead 130 is moved from the B-stage to the a-stage on the first arm 110 (located at about the front end portion of the first arm 110), the front end of the first arm 110 increases in weight, thereby generating pressure on the adjustable bracket 210, and at this time, the movable weight 250 is moved to the F-stage of the second arm 120 (located at about the rear end portion of the second arm 120) by the motor according to the action of the first contact switch 244, thereby putting the first arm 110 and the second arm 120 in a balanced state.
As shown in fig. 7, when the 3D printhead 130 is moved from the B-section to the C-section (located at about the rear end portion of the first arm 110) of the first arm 110, the front end of the first arm 110 is reduced in weight, thereby generating a pulling force on the adjustable bracket 210, and at this time, the movable weight 250 is moved to the D-section (located at about the front end portion of the second arm 120) of the second arm 120 by the motor according to the action of the second contact switch 245, thereby putting the first arm 110 and the second arm 120 in a balanced state.
In addition, the sensing device 240 may be a pressure sensor, and the pressure sensor detects the pressure and the tensile force applied to the adjustable bracket 210 and transmits the pressure and the tensile force to the motor, so as to control the movement of the movable weight 250.
As shown in fig. 2, the adjustable bracket 210 includes a first bracket 211 and a second bracket 212 that are detachably connected, the first bracket 211 is further connected to the first arm 110, and the second bracket 212 is further connected to the adjustable rail 220. As shown in fig. 2, the first bracket 211 and/or the second bracket 212 may be connected by fastening means 213.
Wherein the height of the first bracket 211 and/or the second bracket 212 is adjustable. For example, the first bracket 211 and/or the second bracket 212 may each be configured as an electric cylinder.
In adjusting the height of the adjustable bracket 210, the height adjustment thereof may be accomplished by extending the second bracket 212. The height of each extension of the second bracket 212 is the same as the height of the 3D printhead 130 lifted, i.e., the same as the height of each layer structure 300.
The height of the 3D printer 100 may be raised without limitation, but the height of the adjustable bracket 210 needs to be maintained within a certain range. Otherwise, too high a height of the adjustable bracket 210 is detrimental to the stability of the first arm 110. Thereby being adaptable to the further raised 3D print head 130 by adjusting the height of the adjustable rail 220.
The second bracket 212 may be selectively removed while only the first bracket 211 remains when the height of the adjustable rail 220 is adjusted.
As described above, the height of the adjustable rail 220 can be adjusted, and the height of the adjustable rail 220 can be adjusted by installing a plurality of fixing brackets on the ground to continuously raise the same, or by extending supports on a printed building to install the adjustable rail 220, thereby achieving the purpose of adjusting the height of the adjustable rail 220.
It will be appreciated that the support extending over the building may also be an electrical cylinder which may be extended a certain length at a time.
The adjustable track 220 is configured to be identical to the rotational trajectory of the first arm 110. The rotation track of the first arm 110 may be a circle with the upright 140 as a rotation center and the length of the first arm 110 as a radius. The adjustable track 220 may thus be configured as an annular structure as shown in fig. 8, with a radial cross-section configured as a frame structure 222 with a recess 221, as shown in fig. 9. The frame structure 222 may be, for example, an "I" shaped, an "inverted" C "shaped, or the like. The upper surface of the frame structure 222 is used for contacting with the pressure wheel 233, and the recess 221 is used for accommodating the drop-proof wheel 234 to prevent the pressure wheel 233 from dropping off from the frame structure 222.
It should be noted that, the front end of the first arm 110 refers to an end near the adjustable bracket 210, and the rear end refers to an end near the upright 140. The front end of second arm 120 refers to the end proximal to upright 140 and the rear end refers to the end distal from upright 140.
According to a second aspect of the present invention, the present invention provides a method for stabilizing a tower apparatus, and more particularly, to a method for stabilizing a 3D printer 100, comprising the following operation steps.
In a first step, a first end of the adjustable bracket 210 is coupled to the first arm 110 of the 3D printer 100.
In a second step, an adjustable track 220 is provided on the ground. The adjustable track 220 may be an annular structure centered on the upright 140 and having a radius that is the length of the first arm 110.
The pressure wheel 233 at the second end of the adjustable bracket 210 is brought into contact with the adjustable rail 220, and the drop-off preventing wheel 234 is disposed in the recess 221 of the adjustable rail 220.
During operation of the 3D printer, first arm 110 rotates about upright 140, and thus adjustable bracket 210 will move on adjustable track 220 as first arm 110 rotates.
In a third step, when the elevation of the discharge end of the 3D printhead 130 is changed, the elevation of the adjustable bracket 210 and/or the adjustable rail 220 is adjusted such that the second end of the adjustable bracket is located in the same horizontal plane as the discharge end of the 3D printhead 130.
Fourth, when the 3D printhead 130 moves on the first arm 110 toward the front end of the first arm 110, the movable weight 250 on the second arm 120 of the 3D printer 100 is controlled to move away from the 3D printhead 130 according to the pressure borne by the adjustable bracket 210, so that the first arm 110 and the second arm 120 remain balanced.
When the 3D printhead 130 moves on the first arm 110 toward the rear end of the first arm 110, the movable weight 250 on the second arm 120 of the 3D printer 100 is controlled to move toward the 3D printhead 130 according to the tension applied by the adjustable bracket 210, so that the first arm 110 and the second arm 120 remain balanced.
It should be noted that the 3D printer 100 of the present invention may employ a tower type 3D printer of the prior art, such as printers disclosed in chinese patent CN105715052B and chinese patent CN109386135B, which are incorporated herein by reference in their entirety.
