Description

Technical Field

[0001] The invention relates to a beam type hanging device and an operating method. Background Art

[0002] In the metallurgical area, there are many heavy equipment such as large motors installed in some narrow indoor places. Indoor places (such as hydraulic stations) are generally equipped with electric hoists with fixed path beams on the roof to dismantle or install equipment on the ground. The manual operation of the electric hoist button box can hang the electric hoist on the fixed beam and move it above the equipment. Then, the hook on the electric hoist is lowered to the equipment through operation, and the wire rope sling is put on the equipment to lift the equipment, and then it is lifted to the hand-pushed flatbed truck through the fixed beam. However, some equipment is not directly below the fixed beam of the electric hoist. If it is lifted, it will be tilted and tilted, which is not allowed according to safety requirements. This method of lifting equipment, especially lifting heavy equipment, will cause damage to surrounding equipment or personnel due to the swing inertia of the equipment during the lifting process. Serious safety accidents will occur.

[0003] We need a hanging device that can safely dismantle heavy equipment in narrow areas of the factory. At the same time, the device can also use a crane to lift the equipment in a spacious factory, not limited to narrow areas.

[0004] The prior art discloses two types of lifting devices:

[0005] 1. A hanging device (CN201611114994.5): This invention relates to the field of aviation assembly. The hanging device connects products in a zero-gravity adjustment system to realize the final assembly of products in a zero-gravity environment and corresponding testing devices. It belongs to a device for tightly installing and debugging equipment in the aviation field. The device is complex to manufacture and is not suitable for the requirements of lifting equipment in narrow areas of the metallurgical industry.

[0006] 2. A spring crossbeam hanging assembly (CN201520571617.9): This invention relates to a spring crossbeam hanging assembly, which belongs to the field of aircraft assembly. The hanging device is usually composed of a hanging chain, a crossbeam, a secondary beam hanging chain, a secondary beam and a lifting belt, etc., which are used to tie up the aircraft fuselage. Due to the different structures of different models or the different diameters of different fuselage parts, the crossbeam sizes of the hanging devices to be used are also different. If a fixed-size crossbeam is used, different hanging devices are often required when hanging fuselages of different specifications. This device is not suitable for the requirements of lifting equipment in narrow areas of the metallurgical industry.

[0007] Conclusion: ①. Both of the above patents belong to large-scale precision equipment assembly and debugging devices in the aviation field. They are complex to manufacture and are not suitable for use in the metallurgical industry; ②. The above two patents are not suitable for use in narrow areas of metallurgical factories; ③. Both of the above patents cannot meet the safety requirements for lifting equipment; ④. The above two patents cannot lift two sets of equipment at the same time.
