Technical background: At present, the widely used steel hoists in the country are used. The main raw materials for steel chain hoists are carbon steel. Technical background: At present, the common steel hoists and steel chain hoists are widely used in China. The main raw materials for manufacturing are carbon steel. The tool and equipment of this material naturally generate mechanical sparks through internal friction during operation. It works in flammable and explosive gas places, and naturally detonates the gas to explode. Therefore, it is operated by using this tool. Can not effectively prevent the occurrence of fire. At present, the widely used steel hoists are made in China. The main raw materials for steel chain hoists are carbon steel. The tools and equipment of this material naturally generate mechanical sparks through internal friction during operation, which is flammable and explosive. Working in a gas field will naturally cause the gas to explode, so using this tool for operation cannot effectively prevent the fire from happening.
The explosion-proof chain hoist is made of copper alloy, and the friction parts are made of beryllium bronze and aluminum bronze alloy. In the production of aluminum bronze and beryllium bronze explosion-proof tool blanks, the same raw materials are also used, and the blanks of the force-bearing friction parts of the chain hoists are smelted, such as the lifting wheel, the bracelet wheel, the wall plate, the hook, the gear, The gear shaft is processed and integrated by the machine tool according to the technical requirements. The outer casing is made of H62 copper alloy material. The explosion-proof chain hoist of the invention is suitable for flammable and explosive gas places such as petroleum, chemical industry, oil refining, gas production, oil transportation, mine operation and the like. In the operation, the products will not produce mechanical sparks when they collide with each other, and do not detonate gas in flammable and explosive places, effectively prevent fire accidents and ensure national property and personal safety. The positive effects of the present invention are as follows: The present invention is made of a copper alloy, and the friction members are made of beryllium bronze and aluminum bronze alloy.
