The invention belongs to the technical field of cranes, and particularly discloses a tower type attachment crane for bridge construction. The tower type attachment crane for bridge construction comprises a crane body, a bridge and an attachment mechanism. The tower type attachment crane for bridge construction is convenient for a crane body to be connected or detached and is applicable to attachment action of crane bodies of different sizes. Because of cooperation among outer sleeves, adjusting rods, clamping rings, limiting sliding strips, adjusting racks, supporting frames, adjusting bolts and engagement tooth heads, the distance between one outer sleeve and the corresponding adjusting rod can be adjusted so that the crane can adapt to connection between the crane body and bridges with different distances away, the fastening performance is good after adjustment, and looseness is not prone to happening; and because of cooperation among supporting rods, hollow supporting pipe bodies, sliding blocks and supporting springs, the supporting rods and the hollow supporting pipe bodies can move relatively, and furthermore, under the elastic supporting action of the supporting springs, thesupporting rods and the hollow supporting pipe bodies have the elastic supporting effect on each other, and a certain buffer effect is achieved.
本发明公开的属于起重机技术领域,具体为一种桥梁施工用塔式附着起重机,包括起重机本体、桥梁和附着机构,方便对起重机本体连接和拆卸的作用,适用于不同尺寸的起重机本体附着作用;通过外套管、调节杆、夹持圈、限位滑条、调节齿条、支撑框、调节螺栓、啮合齿头的配合作用,使得外套管、调节杆之间的长度可以调节,从而能够适用于不同距离起重机本体、桥梁之间的连接作用,且调节后紧固性较好,不容容易出现松脱的情况;通过支杆、中空支撑管体、滑动块、支撑弹簧之间的配合作用,使得支杆、中空支撑管体能够相对移动,且在支撑弹簧的弹力支撑作用下,使得支杆、中空支撑管体之间具有弹性支撑的作用,具有一定的缓冲效果。
