Advantages and improvement measures of new mobile power supply device for bridge crane

bridge crane is an important tool and equipment to realize mechanization and automation of production process in modern industrial production and lifting transportation. Therefore, the bridge can not allow the existence of air holes. The crane has been widely used in indoor and outdoor industrial and mining enterprises, iron and steel chemical industry, railway transportation, port terminals, logistics turnover and other departments and places. In the process of using the bridge crane, new problems will be encountered continuously. Engineers will constantly transform and improve the lifting machinery according to the problems reflected by the users

use and improvement of bridge crane safety sliding contact wire is a new type of mobile power supply device, which gradually replaces the old bare angle iron and copper bar sliding contact wire with its superior performance of insulation, safety, temperature resistance, vibration resistance and energy saving. The safety sliding contact line is composed of a smooth and flat T2 copper bar or an aluminum profile embedded with a wear-resistant conductor filled in an engineering plastic pipe or groove plate as the carrier fluid, and is combined into a transmission pipe. There is an open groove under the pipe to facilitate the operation of the collector, and the high wear-resistant copper based graphite brush of the collector guides the electric force to the working appliance

the overhead crane is easy to cut off power during use, sometimes sparks are generated in the transmission conduit, and in serious cases, the collector is replaced too frequently, affecting production. To this end, the following changes have been made:

1. Increase the strength and elasticity of the spring between the two relative brushes of the collector to ensure that the spring can recover freely

2. Increase the chamfer of collector brush and polish it smooth

3. Deepening. Reinforce the spring seat in the collector to ensure that the recovery spring of the brush is not easy to string in operation

4. The connecting block at the connection of two sections of safety sliding contact wire shall be chamfered to ensure the smooth transition of the collector. At the same time, the structural capacity is generally 1000 lb. in order to ensure the normal use of the safe sliding contact line, the standardized operation of the crane operator, the regular maintenance and regular inspection of the repairman are also essential
