Description
Technical Field
[0001] The invention relates to the technical field of conveying devices, in particular to an automatic conveying device for a coiled scaffolding upright. Background Art
[0002] Scaffolding is a working platform set up to ensure the smooth progress of each construction process. Among them, disc scaffolding is a new type of scaffolding, which is mainly composed of vertical poles with disc buckles, cross bars and connecting sleeves. The two ends of the cross bar are respectively connected to the disc buckles on the two adjacent vertical poles. The connecting sleeve is located at the end of the vertical pole and is used to connect the adjacent vertical poles.
[0003] In the related art, in the production process of vertical poles with disc buckles, a conveying assembly is usually used to convey the vertical poles to the welding station. The conveying assembly mainly includes a transfer rack connected to the finished product rack equipped with the vertical poles, a moving part for moving the vertical poles and a conveying rack. The vertical poles are rolled from the finished product rack to the transfer rack. There is a height difference between the transfer rack and the conveying rack. The moving part is located on the transfer rack and conveys the vertical poles to the conveying rack, so that the conveying part on the conveying rack can convey the vertical poles to the welding station for processing.
[0004] The pole rolls from the finished product rack to the transfer rack under its own gravity. During the rolling process of the pole, the moving track is prone to deviation, so that the pole is not facing the moving part, which can easily cause the pole to fall during the process of moving from the transfer rack to the conveying rack, thereby affecting the efficiency of the conveying device to transport the pole, so it needs to be improved.

[0038] like Figure 1 to Figure 10 As shown, a temporary expansion unit 7 is provided under the main beam 3, and the temporary expansion unit 7 includes a central support 701, a pump 702 and an airbag 703.

[0040] like Figure 1 to Figure 10 As shown, two lower diameter-changing units 5 and two upper driving units 6 are symmetrically arranged front to back.
[0041] When used specifically, according to the working conditions on site, the upper frame 1 is positioned and supported. The conveying assembly 4 and the foreign matter cleaning bucket 9 below the upper frame 1 clean the floating dust and large pieces of bonded foreign matter on the vertical pole with the buckle respectively.
[0042] The working principle of the conveying assembly 4 to clean the floating dust on the upright pole is as follows: the driving motor 602 drives the belt 401 and the shovel blade 402 to rotate through the driving wheel 603, and the shovel blade 402 shovels up the floating dust. After being shoveled up, the floating dust approaches the wide-mouth suction head 405, and is sucked into the negative pressure suction device 403 through the suction pipe 404 under the action of negative pressure.
[0043] The working principle of the conveying component 4 for identifying large foreign objects is as follows: the shielding net 406 under the wide-mouth suction head 405 has the function of blocking large and compact foreign objects, thereby preventing large and compact foreign objects from blocking the suction pipe 404. When large and compact foreign objects are thrown up by the shovel blade 402 and hit the shielding net 406, the vibration sensor 407 on the shielding net 406 can detect a large vibration amount and transmit a signal of "the shielding net 406 collides with the large and compact foreign object" to the controller 11.
[0044] After the controller 11 receives the signal that "the shielding net 406 collides with a large and compact foreign object", the conveying component 4 remains in place to continue to perform the floating dust shoveling and negative pressure suction work for a certain period of time. One purpose of maintaining the floating dust shoveling and negative pressure suction work for a certain period of time is to avoid a large amount of floating dust being thrown up to the shielding net 406 by the shovel blade 402 at the same time, causing the vibration sensor 407 to report a false signal. Another purpose of maintaining the floating dust shoveling and negative pressure suction work for a certain period of time is that before the large and compact foreign objects are processed separately later, the continuous work of the negative pressure suction device 403 can absorb as much floating dust as possible, avoiding the immediate suspension of the negative pressure suction device 403, which causes a large amount of floating dust to escape and affect the collection accuracy.
[0045] Then the driving motor 602 and the negative pressure suction device 403 in the conveying assembly 4 are stopped, and the lower diameter reducing unit 5 begins to adjust the effective wheel diameter at the bottom of the belt 401, avoiding large and compact foreign objects by reducing the effective wheel diameter. Specifically, the lifting electric push rod 516 is extended, so that the tilted parking shaft 511 is in a horizontal state under normal conditions (while the parking shaft 511 tends to be horizontal, the top of the lifting electric push rod 516 slides along the bottom of the main beam 3 to adapt to the position change of the outer end connecting plate 514). After the electric push rod 506 is retracted and the fork 507 is driven to rise, the electric control trolley 505 moves in the direction toward the support arm 501. Then the fork 507 falls again and contacts a transmission disk 509. At this time, the electric control trolley 505 moves in the direction away from the support arm 501, thereby driving the transmission disk 509 below to move from the lower shaft 502 to the horizontal parking shaft 511 through the universal coupling 510. The parking electric push rod 512 in the parking slot 5111 drives the blocking piece 513 to extend and abut against the transmission disc 509 pushed onto the parking shaft 511. Subsequently, the electric control trolley 505 and the shifting electric push rod 506 move the shift fork 507 to the initial position, so that the ball 508 on the shift fork 507 fits with the transmission disc 509 at the end of the lower shaft 502. At this time, the lifting electric push rod 516 retracts back to the original position, so that the parking shaft 511 and the part of the transmission disc 509 suspended on the parking shaft 511 remain in a tilted state.
[0046] The bottom of the belt 401 is only in contact with the transmission disc 509 at the end of the lower shaft 502. Since the transmission disc 509 at the end of the lower shaft 502 has a smaller diameter, the bottom support force of the belt 401 is insufficient, causing the belt 401 to relax as a whole. The upper elastic telescopic rod 601 in the upper drive unit 6 is extended to maintain the tension of the belt 401. At this time, the effective radius of the top of the belt 401 remains unchanged, while the effective radius of the bottom is reduced, and a certain gap is exposed between the belt 401 and the bottom of the shovel blade 402.
[0047] When the effective radius at the bottom of the belt 401 decreases, the foreign matter cleaning electric push rod 8 extends, so that the foreign matter cleaning bucket 9 is close to the vertical pole. The staff controls and pushes the upper frame 1 forward for a certain distance, and the large and compact foreign matter is not crushed due to the gap between the belt 401 and the bottom of the shovel blade 402, and can be collected in the foreign matter cleaning bucket 9.
[0048] At this time, part of the floating dust cleaning and large-volume and tight foreign matter cleaning are completed, and the lower variable diameter unit 5 restores the previous bottom effective wheel diameter to adapt to the subsequent floating dust cleaning operation. Specifically, the lifting electric push rod 516 is extended to make the parking shaft 511 horizontal again, and the blocking piece 513 is retracted by the parking electric push rod 512. The pump 702 in the temporary expansion unit 7 inflates the airbag 703 so that the airbag 703 props up the bottom center of the belt 401. Because the belt 401 is fixed with multiple rigid shovels 402, when the bottom center of the belt 401 is supported, the bottom edge of the belt 401 is also expanded synchronously and the effective wheel diameter is temporarily expanded. Subsequently, the electric control trolley 505 and the electric push rod 506 drive the fork 507 to push the transmission disk 509 previously moved to the parking shaft 511 back to the lower shaft 502. Under the expansion effect of the airbag 703 on the belt 401, the transmission plate 509 can enter the inner side of the belt 401 from the expanded edge of the belt 401, and finally stay at the end of the lower shaft 502, completing the operation of restoring the effective wheel diameter of the belt 401.
[0049] It is worth pointing out that: keys are fixedly provided on the parking shaft 511 and the lower shaft 502, and a keyway adapted to the key is provided in the transmission disc 509. The cooperation between the keyway and the key helps to maintain a good power transmission relationship between the transmission disc 509 and the lower shaft 502. At the same time, the part of the lower end of the shift fork 507 that contacts the transmission disc 509 is magnetic, so that when the transmission disc 509 moves between the parking shaft 511 and the lower shaft 502 through the universal coupling 510, the transmission disc 509 that contacts the shift fork 507 only moves horizontally and does not rotate arbitrarily, so that the transmission disc 509 can maintain a sliding plug-in relationship with the key after passing through the universal coupling 510.
[0050] The lower variable diameter unit 5 can not only be used to avoid large and compact foreign objects, but also has the function of adjusting the strength of light floating ash throwing. Specifically, when the throwing strength needs to be adjusted, the lower variable diameter unit 5 is executed according to the above process to reduce the effective wheel diameter at the bottom of the belt 401, while the height-adjusting electric push rod 2 is extended, so that the main beam 3 and the conveying assembly 4 move downward synchronously. At this time, the belt 401 and the shovel blade 402 with the reduced effective wheel diameter at the bottom are in contact with the vertical pole again. When the output power of the drive motor 602 remains unchanged, the bottom of the belt 401 with the reduced effective wheel diameter has a higher rotational linear velocity, and the shovel blade 402 has a stronger throwing ability for the floating ash in contact.
[0051] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
