Amusement equipment disassembly and maintenance minor problem solving skills 212 times , It is necessary for the on-site maintenance personnel to disassemble and overhaul the internal parts. During the disassembly process, some small problems with screws and nuts will be encountered. Let me tell you some tips to solve it.
1. Disassembly of the broken screw< br />Drill holes on the screws, drive into the multi-stone hardened steel cones, and unscrew the screws. Pay attention to the impact force not to be too strong to prevent damage to the female thread. If the screw is broken in the center of the broken end below the surface of the machine, tap the counter-rotating thread in the hole and use the corresponding counter-rotating screw or tap to unscrew it; if the screw is broken above the surface of the machine, add it to the broken head. Weld the screw out, or use a hacksaw to cut a groove on the protruding broken end, and then screw it out with a screwdriver. Use a drill to drill out the entire amusement park equipment screw, replace the screw with a slightly larger diameter than the original screw, and select the corresponding nut.

2. Disassembly of rusty screws
Knock the sides of the screws (screws, bolts, nuts, etc.) with your hands to shake the rust layer, and then unscrew it; you can slightly tighten it in the tightening direction first Move it a little, and then twist it in the opposite direction, so that it is screwed out in reverse steps; pour some kerosene around the screw, or put cotton yarn dipped in kerosene, soak it for about 20 minutes, use the strong penetrating force of kerosene to penetrate into the rust layer, and gradually Unscrew the thread after loosening it.

If the above methods are all invalid, if the playground equipment parts are permitted, a blowtorch can be used to quickly heat the nut or thread around to expand the part or nut, and then quickly screw it

3, Disassembly of group threaded connection
In addition to the removal of a single thread, the following points must be done: First, loosen each bolt 1~2, and then follow the regulations After four weeks, the diagonals in the middle are disassembled one by one, so as not to concentrate on the latter screw body after the force, which may cause difficult disassembly or deformation and damage of parts. The parts that are difficult to dismantle should be dismantled first.
