[0002] Square tube is a name for square tube and rectangular tube, that is, steel tube with equal and unequal side lengths. It is made by rolling steel strip after processing. Galvanizing is to coat a layer of zinc on the surface of steel to protect the steel from corrosion. It can increase the corrosion resistance of steel to a certain extent and make it have a longer service life.

[0003] At present, when square tubes are galvanized, the lifting mechanism fixes them by chains and then lifts them into the galvanizing pool. However, the positioning method of the chain is cumbersome and not stable enough, which can easily lead to problems such as displacement of the square tubes. Therefore, a lifting mechanism for galvanized square tubes is proposed, which replaces the chain fixation by extrusion clamping and is more stable. Summary of the invention

[0004] In view of the problems in the prior art, the utility model provides a galvanized square tube hoisting mechanism, which replaces chain fixation by extrusion clamping and is more stable.

[0008] When the positioning tube A and the positioning tube B are located inside the openings at both ends of the square tube, extend the telescopic rods A, B, C and D respectively to contact the inner walls of the square tube respectively, thereby achieving the extrusion positioning effect, and then rotate the corresponding tightening bolts A, B, C and D respectively to squeeze the corresponding telescopic rods for fixing. The extrusion clamping method replaces the chain fixation, which is more stable.

[0009] Specifically, a hook block is provided on the top of the hanger, and a hanging hole is opened on the top of the surface of the hook block.

[0010] By adopting the above technical solution, the hook block is used to facilitate the hooking connection of the lifting mechanism.

[0011] Specifically, the L-shaped bracket A and the L-shaped bracket B are slidably connected to the top slide rail A and the slide rail B through sliders, and the driving ends of the electric push rod A and the electric push rod B are connected to the L-shaped bracket A and the L-shaped bracket B, respectively.

[0012] By adopting the above technical solution, the slide rails A and B cooperate with the L-shaped brackets A and B to slide smoothly.

[0013] Specifically, a tightening bolt A and a tightening bolt B are respectively penetrated through the top and bottom of one side of the positioning tube A through reserved threaded holes.
