The invention discloses a dustproof device for a side bearing of a railway wagon. The device comprises an adjusting base plate and a wearing plate which are arranged at the lower end of an upper side bearing body assembly, and an upper mounting seat is clamped between the adjusting base plate and the wearing plate; a lower mounting seat with the same shape as the bottom end surface of the lower side bearing body assembly is movably mounted between the lower side bearing body assembly and the swing bolster; a dust cover is communicated between the upper mounting seat and the lower mounting seat, an upper interface of the dust cover is clamped in the clamping groove of the upper mounting seat, and a lower interface of the dust cover is clamped in the clamping groove of the lower mounting seat; the dustproof cover is of a variable cross-section structure from top to bottom, and a variable cross-section telescopic corrugated structure is arranged on the lower middle portion of the dustproof cover. When vertical or longitudinal displacement occurs between the upper side bearing body assembly and the lower side bearing body assembly, the telescopic corrugated structure can be shrunk or expanded along with deformation. No wind and sand enter the dustproof device, and abrasion and corrosion of components in the upper side bearing structure and the lower side bearing structure caused by the wind and sand can be avoided to the maximum extent.
本发明公开了一种铁路货车旁承防尘装置。该装置包括:所述上旁承体组成下端的调整垫板和磨耗板,调整垫板和磨耗板之间夹持有上部安装座;所述下旁承体组成与摇枕之间活动安装有与下旁承体组成底端面形状相同的下部安装座;上部安装座和下部安装座之间连通有防尘罩,所述防尘罩上接口卡紧于上部安装座卡槽内,下接口卡紧于下部安装座卡槽内;所述防尘罩由上至下为变截面结构,且防尘罩中下部设置有变截面可伸缩波纹结构;当上旁承体组成和下旁承体组成之间发生垂向或纵向位移时,可伸缩波纹结构能够随着形变缩小或扩大。本发明防尘装置内部无风沙进入,能最大程度避免风沙造成上、下旁承结构内部构件的磨损和腐蚀。
