The invention discloses a special hoisting device for hoisting an assembly type high-voltage line protective shed and a using method, and belongs to the technical field of hoisting of assembly type high-voltage line protective shed prefabricated parts. The special hoisting device comprises a main beam truss and a hoisting trolley, the main beam truss is of a double-truss structure and is composed of a plurality of main beams, and the hoisting trolley is of a double-truss structure; connecting holes are formed in the ends of the main beams, every two adjacent main beams are fixedly connected through a connecting beam, a rail is fixedly installed on the upper plane of a truss of the main beams, the lifting trolley is arranged on the rail, and a movable pulley is arranged on the lifting trolley and matched with the rail. Through the arrangement of the double trusses, the double lifting trolleys, the winches and the lifting appliances, when the prefabricated parts of the assembly type high-voltage line protective shed are lifted, the lifting appliances for lifting the prefabricated parts can be lifted into the special trusses through the double lifting trolleys and the winches by the special trusses, the lifting height is guaranteed, and therefore the height of the gantry crane structure is reduced; and the safety distance with the high-voltage line is increased.
本发明公开了装配式高压线防护棚预制构件吊装技术领域的一种用于装配式高压线防护棚吊装的专用起吊装置及使用方法,包括主梁桁架和起吊小车,所述主梁桁架为双桁架结构,所述主梁桁架由多条主梁组成,主梁的端头位置设置有连接孔,相邻的两主梁之间通过连系梁进行固定连接,所述主梁桁架的上平面上固定安装有轨道,所述轨道上设置有所述起吊小车,所述起吊小车上设置有移动滑轮与所述轨道相互配合。本发明通过设置的双桁架、双起吊小车、卷扬机、吊具,使得装配式高压线防护棚预制构件吊装时,专用桁架可以将吊装预制构件的吊具通过双起吊小车卷扬机提升至专用桁架内部,保证提升高度,从而降低龙门吊结构高度,增大与高压线的安全距离。
