The auxiliary device for hoisting the oil drum gas cylinders solves the problems that the traditional auxiliary device for hoisting the oil drum gas cylinders usually adopts a mode of matching a chain with a limiting groove to fix the oil drum gas cylinders in different sizes, and when the auxiliary device is hoisted, the edge of the end plate is provided with a lifting lug, and when the auxiliary device is hoisted, a lifting hook of a sling can be directly hung on the lifting lug for hoisting.

Further, the connecting rod is detachably connected with the end plate. Part of the connecting rod can be removed when the oil drum gas cylinder is loaded or unloaded.

Further, the end plate is provided with a slot hole with the center pointing to the edge, a plurality of concave reaming holes are arranged on the outer side of the slot hole, and the reaming center is positioned on the center line of the slot hole. The reaming is used as a limiting hole, the connecting rod is positioned at the outer side part of the end plate and is sleeved with a limiting gasket, the gasket is embedded into the reaming to play a limiting role on the connecting rod, and the diameter of the hollow cage can be adjusted so as to be suitable for oil drum gas cylinders with different diameters.

Furthermore, the connecting rod adopts double nuts at the joint of the connecting rod and the unilateral end plate, so that on one hand, the short plate is fixed, and on the other hand, the length of the hollow cage can be adjusted, so that the hollow cage is suitable for oil drum gas cylinders with different heights. And a limiting bulge is arranged on the inner side of the joint of the connecting rod and the end plate.

Further, the connecting rod is fixed on the end plate through a nut, the connecting rod is disassembled in a screwing mode, and the connecting rod can be fixed in a replaced mode through a pin locking hole.

The beneficial effects of the utility model are as follows: the cage type lifting appliance formed by the end plates and the connecting rods greatly reduces the use of raw materials, lightens the dead weight of the lifting appliance, reduces the lifting load and has a strong safety anti-falling effect; compared with the simple structure, the utility model is more suitable for lifting a single oil drum gas cylinder; the setting of slotted hole and indent reaming (spacing hole) on the end plate can realize the regulation of cage body diameter, and the connecting rod adopts the fixed setting of double nut with unilateral end plate can realize the regulation of cage body length, is applicable to the oil drum gas cylinder handling of different diameters different co-altitude.
