Description

Technical Field

[0001] The invention belongs to the technical field of galvanizing automation, and in particular relates to an automatic hanging turntable mechanism for galvanizing a disc-type scaffolding crossbar. Background Art

[0002] The disc-type scaffolding is an upgraded version of the traditional scaffolding. As a new type of building support system, it can be composed of different shapes and load-bearing capacities according to different construction requirements to carry out single, group size, double row scaffolding and support frames and other multi-functional construction equipment, including vertical poles, cross bars, diagonal bars, bases, standard bases, top supports and other main components. Among them, the link node of the disc-type socket scaffolding is a disk fixed to the vertical pole, and there are several socket holes on the disk, such as Figure 1 As shown, a disc slot 11 is provided at the end of the cross bar 1, and a through hole 12 is passed through the groove wall of the disc slot 11. The through hole 12 on one side of the disc slot 11 is a pin hole 121, and the other side is a avoidance hole 122. A wedge-shaped pin 13 is provided in the pin hole 121, and the tip of the wedge-shaped pin 13 is provided with an anti-slip block 131. The anti-slip block 131 is located at the disc slot 11, and the outline of the anti-slip block 131 is larger than the diameter of the pin hole 121, which can effectively prevent the pin 13 from falling off or even being lost from the pin hole 121. The tail size of the wedge-shaped pin 13 is larger than the diameter of the pin hole 12. When mating, the pin 13 is pulled to one side of the pin hole 121, the disc slot 11 is matched with the disc of the vertical rod, and the pin 13 is inserted into the socket hole of the disc. The tail of the pin 13 and the wall of the pin hole 121 are fully squeezed to generate static friction to achieve a fixed connection.

[0003] In order to make the surface of the crossbar 1 uniform, corrosion-resistant and wear-resistant, and more beautiful in appearance and extend its service life, it is generally necessary to perform hot-dip galvanizing treatment. Since the end structure of the cross bar 1 is relatively complex, only the through hole 12 can be used as the hanging hole of the galvanized hanger 6. The anti-slip block 131 of the latch 13 itself is mostly riveted and cannot be easily disassembled. The position of the latch 13 in the through hole 12 is not fixed, which increases the difficulty of matching the through hole 12 with the galvanized hanger. For this reason, most companies use pure manual galvanizing or remove the latch 13 before hot-dip galvanizing. The inventor believes that pure manual operation has high labor intensity, poor working environment, unstable work efficiency, and cannot meet production needs. Forcibly removing the latch 13 before hot-dip galvanizing not only adds a removal process, but also requires the latch 13 to be hot-dip galvanized separately to ensure consistent appearance. After treatment, it needs to be assembled with the latch hole 121 again, which undoubtedly increases a lot of operating costs and time costs for manufacturers. For this reason, it is necessary to design an automatic hanging turntable mechanism for galvanizing the disc-type scaffold cross bar.

[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance understanding of the background of the present disclosure and therefore may contain information that does not constitute prior art. Summary of the Invention

[0005] Through research, the inventor found that the position of the pin in the through hole is not fixed, which increases the difficulty of matching the through hole with the galvanized hanger, resulting in the through hole being unable to achieve automatic hooking with the galvanized hanger, and thus unable to achieve automatic galvanizing of the disc-type scaffolding crossbar.

[0024] In order to better understand the purpose, structure and function of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0025] The serial numbers assigned to the components herein are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" mentioned in this disclosure, unless otherwise specified, includes both direct and indirect "connections". In the description of this application, it should be understood that the orientation or positional relationship indicated by the directional terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and brief description, and does not indicate or imply that the device or unit referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation to this application.

[0026] As shown in the attached figure Figures 2 to 5 As shown, an automatic hanging turntable mechanism for galvanizing the crossbar of a disc-type scaffold is designed, comprising a disc 2, wherein the disc 2 is equipped with a rotating power source, and several articulated arms 3 are evenly distributed along the outer edge of the disc 2. The articulated arms 3 are vertically articulated to the disc 2, and a concave magnetic member 31 is provided at the outer end of the articulated arm 3. The pointing trajectory of the concave surface of the magnetic member 31 coincides with a radial ray of the disc 2. A vertically articulated piston cylinder 4 is provided on the vertical plane where the articulated arm 3 moves, and the piston rod of the piston cylinder 4 is connected to a concave magnetic member 41. A rotary alignment mechanism is provided above the magnetic member 31, and the rotary alignment mechanism comprises a rotating motor, which is vertically connected to a shift fork 5 through a reducer. The rotary alignment mechanism is equipped with an alignment sensor, and the disc 2 is provided with a plug-in pin electromagnet 21 on the inner side of the articulated arm 3, and the height position of the plug-in pin electromagnet 21 is higher than the height position of the articulated arm 3.

[0027] When in use, the crossbar 1 to be galvanized can be vertically held by the arrangement of the magnetic member 31 and the magnetic member 41, the alignment sensor senses the angle of the crossbar 1, the fork 5 is inserted into the gap at the upper end of the crossbar 1 and rotated until the alignment sensor issues an instruction that the position is correct, and the fork 5 can be withdrawn, thereby automatically realizing the rotation alignment of the crossbar 1. Figure 4 As shown, after the pin pulling electromagnet 21 pulls the pin 13 to one side, it can ensure that there is no obstacle in the avoidance hole 122. After the disc 2 continues to rotate until the magnetic element 31 is close to the hanger 6, as shown in FIG. Figure 3 As shown, the angle of the cross bar 1 can be adjusted by contracting and extending the piston rod of the piston cylinder 4, so that the avoidance hole 122 and the hanger 6 can be automatically hooked and matched, thereby solving the problem that the position of the pin 13 in the through hole 12 is not fixed, which increases the difficulty of matching the through hole 12 with the galvanized hanger 6, resulting in the through hole 12 being unable to achieve automatic hooking and matching with the hanger 6.

[0028] In the above implementation, three embodiments are listed to implement the above technical solution:

The articulated arms 3 are vertically articulated to the disc 2, and a concave magnetic member 31 is provided at the outer end of the articulated arm 3.

[0031] Wherein, the rotating power source includes a motor, and the motor is equipped with a disc feeder, which is connected to the middle of the disc 2. When the motor is turned on, the motor drives the disc feeder, and the disc feeder acts as a decelerator to link the disc 2; the articulated arm 3 is hinged to the upper surface of the disc 2, and the piston cylinder 4 is hinged to the lower surface of the disc 2; the disc 2 is provided with a avoidance notch 22 on the outside of the projection of the articulated arm 3, which can shorten the rotation radius of the magnetic element 31 and the cross bar 1, effectively reduce the centrifugal force, and at the same time, avoid the edge of the disc 2 from interfering with the outer side of the cross bar 1, affecting the galvanizing effect; the magnetic element 31 is an electric The magnet, the magnetic member 31 is a V-shaped structure; the plug-in pin electromagnet 21 is cylindrical, the plug-in pin electromagnet 21 is fixed to the connecting plate, the connecting plate is fixed to the upper surface of the disc 2, and the axis of the plug-in pin electromagnet 21 is aligned with the center line of the magnetic member 31, which can make it easier to pull out the pin 13; the magnetic member 41 is an electromagnet; the magnetic member 41 is a V-shaped structure; the V-shaped structure can be V-shaped, asymmetric V-shaped, approximate V-shaped with an arc surface, etc., so as to achieve at least two surfaces in contact with the side surface of the cross bar 1, which can effectively prevent the cross bar 1 from falling off when the fork 5 rotates the cross bar 1.

[0032] Example 2

[0033] like Figure 5 As shown, this embodiment discloses an automatic hanging turntable mechanism for galvanizing the disc-type scaffolding crossbar. The difference between this embodiment and Example 1 is that the outer end of the piston rod of the piston cylinder 4 is also connected to an articulated arm 3, and the outer end of the articulated arm 3 is connected to the magnetic member 41. Through the second-level articulation, the magnetic member 41 can obtain a larger range of motion, thereby providing a larger range of rotation angles for the crossbar 1, which is convenient for cooperation with the hanger 6.

[0034] Furthermore, the hinge at the root of the piston cylinder 4 and the hinge at the outer end of its piston rod are both provided with limit stops to control the movable angle of the hinge within 30 degrees, so as to facilitate automatic coordination with the hanger 6.
