Description

Technical Field

[0001] The utility model relates to the technical field of coal-fired unit transportation, in particular to a transfer device for coal-fired unit transportation. Background Technique

[0002] A coal-fired power generation unit is a mechanical device that converts the chemical energy of fossil fuels such as coal into electrical energy. A coal-fired power generation unit mainly consists of a combustion system (with a boiler as the core), a steam-water system (mainly composed of various pumps, feedwater heaters, condensers, pipelines, water-cooled walls, etc.), an electrical system (mainly including a steam turbine generator, a main transformer, etc.), and a control system. The first two generate high-temperature and high-pressure steam; the electrical system realizes the conversion from thermal energy and mechanical energy to electrical energy; the control system ensures the safe, reasonable, and economical operation of each system. As a traditional power generation method, coal-fired power generation also has its drawbacks and deficiencies. For example, the emissions of acidic gases such as SO2 and NOX directly emitted by coal combustion are increasing, resulting in an increase in acid rain in China, and the dust pollution has an adverse impact on people's lives and the growth of plants. Therefore, it is necessary to continuously improve the process of coal-fired power generation and use various technologies to improve power generation efficiency and reduce environmental pollution. For example, desulfurization and dust removal treatment are carried out on soot or natural gas is burned instead. When transporting the parts of a coal-fired unit, a transfer device is needed to transfer them to a transport vehicle such as a truck. The coal-fired unit parts fixedly placed on the traditional transfer device are inconvenient to transfer and require the assistance of a crane to achieve the transfer of the parts. For this reason, we propose a transfer device for coal-fired unit transportation. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the existing defects and provide a transfer device for coal-fired unit transportation. By starting the electric telescopic rod to make the conveying roller snap into the inside of the through groove, and cooperating with the pushing plate, the placed coal-fired unit parts can be pushed, and the height of the transfer frame can be adjusted by cooperating with the hydraulic rod, so as to facilitate subsequent transfer, and the problems in the background technique can be effectively solved.

[0010] Furthermore, it further includes a main linear motor and a pushing plate. There are two main linear motors, which are respectively fixed on the left and right side surfaces inside the transfer rack. The inner side surface of the moving sub-base of the main linear motor is connected to the end of the pushing plate.
