The invention belongs to the technical field of sliding contact line defrosting, and particularly discloses a door type travelling crane sliding contact line defrosting device which comprises a base and a heating bin, connecting blocks are arranged on the two sides of the base, protruding blocks are arranged on the two sides of the bottom of the heating bin, the connecting blocks are in bolted connection with the protruding blocks, openings are formed in the two ends of the heating bin, and a power receiving wheel is rotationally connected to the opening in one end of the heating bin. A hot air gun is arranged in the heating bin, an adjusting assembly used for adjusting the height of the heating bin is arranged on the base, and the hot air gun is provided with a control assembly used for turning on and off the hot air gun regularly. The problems that a travelling crane cannot be used normally due to the fact that frost layers can be formed on exposed metal surfaces of a sliding contact line, a pantograph and the like, abrasion of a power receiving wheel is aggravated by the frost layers, and the maintenance cost is increased are solved. The sliding contact line is defrosted by arranging the hot air gun and the heating bin, and the hot air gun and the heating bin are opened and closed regularly, so that the sliding contact line can be prevented from being frozen or frosted, the smoothness of electrical connection is guaranteed, the problem of unstable current is reduced, energy is saved, and the maintenance frequency is reduced.

    本发明属于滑触线除霜技术领域,具体公开了一种门式行车滑触线除霜装置,包括底座和加热仓,底座的两侧设有连接块,加热仓的底部两侧设有凸块,连接块与凸块螺栓连接,加热仓的两端设有开口,加热仓的一端开口上转动连接有受电轮,加热仓内设有热风枪,底座上设有用于调节加热仓高度的调节组件,热风枪设有用于定时开关热风枪的控制组件。针对滑触线、集电弓等裸露金属表面会形成霜冻层,导致行车不能正常使用,并且霜冻层加剧受电轮的磨损,增加维护成本的问题。本发明通过设置热风枪以及加热仓对滑触线除霜,并且定时开启和关闭,可以防止滑触线结冰或结霜,从而保障电气连接的畅通,减少电流不稳定的问题,节约能源,并且减少维护频率。
