Description

A galvanized automatic hanger process for the buckle-type scaffolding cross-bar

technical field

The invention belongs to the technical field of galvanizing intelligent manufacturing, and in particular relates to a galvanized automatic pendant technology for a coil-type scaffold cross-bar.

Background technique

As a new type of building support system, the buckle-type scaffolding can be composed of different shapes and load-bearing capacities according to different building construction requirements, and can be used as construction equipment with various functions such as single, group size, double-row scaffolding and support frames. Including vertical rods, horizontal rods, inclined rods, bases, standard bases, jacking and other components. Among them, the link node of the disc buckle socket scaffold is a disc fixed on the vertical pole, and several socket holes are arranged on the disc, as shown in Figure 1, the end of the cross bar 1 is provided with a disc slot 11, and the disc slot 11 is arranged on the disc. The groove wall of the disc slot 11 runs through a through hole 12, and the through hole 12 part on one side of the disc slot 11 is a bolt hole 121, and the other side is an escape hole 122, and a wedge-shaped latch is arranged in the bolt hole 121. 13. The tip of the wedge-shaped bolt 13 is provided with an anti-off block 131, which is located at the disc slot 11. The outline of the anti-off block 131 is larger than the caliber of the pin hole 121, which can effectively prevent the bolt 13 from slipping The hole 121 falls off or even gets lost. The size of the tail of the wedge-shaped latch 13 is larger than the diameter of the latch hole 12. When mating, the latch 13 is pulled to one side of the latch hole 121, and the disc slot 11 is paired with the disc of the vertical rod. The latch 13 stretches into the socket hole of the disc, and the afterbody of the latch 13 is fully extruded with the wall of the latch hole 121 to generate static friction to realize a fixed connection.

Regardless of whether the new crossbar 1 or the old crossbar 1 is recycled and reused, in order to make the crossbar 1 have a uniform surface texture, anti-corrosion and wear resistance, and a more beautiful appearance, and prolong its service life, it is generally necessary to hot-dip galvanize the crossbar 1 . Because the structure of the end of the cross bar 1 is relatively complicated, only the through hole 12 can be used as the hanging hole of the galvanized hanger 6. The anti-off block 131 of the bolt 13 itself is mostly riveted and cannot be easily disassembled. The bolt 13 is in the through hole 12. The central position is not fixed, which increases the difficulty for the cooperation of the through hole 12 and the galvanized hanger. For this reason, enterprises often use purely manual galvanizing or remove the pin 13 before hot-dip galvanizing. The inventor believes that purely manual operation The labor intensity is high, the working environment is harsh, and the work efficiency is unstable, which cannot meet the needs of production. The bolt 13 is forcibly removed before hot-dip galvanizing. After the hot-dip galvanizing treatment, it is necessary to realize the assembly with the pin hole 121 again, which will undoubtedly increase a lot of operating costs and time costs for the manufacturer. Therefore, it is necessary to design a ring-type scaffolding cross-bar galvanized automatic pendant craft.

It should be noted that the information disclosed in the above Background section is only for enhancement of understanding of the background of the disclosure and therefore it may contain information that does not constitute prior art.
