The invention discloses a lifting support rod capable of being steplessly adjusted in the length direction, which comprises a support rod jacket, a fixed lifting lug in bolted connection with a left end flange of the support rod jacket and a hydraulic rod flange of a hydraulic cylinder, and a movable lifting lug which penetrates through a plugging flange, is inserted into the plugging flange from the right end of the support rod jacket and is welded and fixed with an end cover flange of the hydraulic cylinder, the friction plate is plugged into the inner wall of the right end of the supporting rod jacket in the circumferential direction; the movable lifting lug comprises a movable lifting lug main plate, two movable lifting lug reinforcing semicircular pipes are fixed to the front side wall and the rear side wall of the movable lifting lug main plate respectively, lifting lug holes are formed in the upper side wall and the lower side wall of the right end of the movable lifting lug main plate respectively, lug hole reinforcing plates are arranged, the two movable lifting lug reinforcing semicircular pipes form a circular pipe shape, and an integral cavity is formed in the left portion of the circular pipe. A hydraulic cylinder is installed. The overall length of the supporting rod can be adjusted by controlling the telescopic length of the hydraulic rod of the hydraulic cylinder; the problem that the application range of an existing supporting rod is limited is solved. And meanwhile, the matching efficiency of the supporting rod and the hoisting rigging is improved, the number of supporting rods with different specifications is reduced, and the construction cost is reduced.

    本发明公开了一种长度方向无级可调的吊装撑杆,包括一撑杆外套,与撑杆外套左端法兰连同液压缸液压杆法兰一起螺栓连接的固定吊耳,穿过封堵法兰后,由撑杆外套右端插入其内部并与液压缸端盖法兰焊接固定的活动吊耳,塞入撑杆外套右端内壁圆周方向的摩擦片;其中,活动吊耳包括活动吊耳主板,两个活动吊耳加强半圆管分别固定在活动吊耳主板的前后侧壁上,活动吊耳主板右端的上下侧壁上分别开有吊耳孔,并设有耳孔加强板,所述的两个活动吊耳加强半圆管组成圆管形且左部具有整体空腔,用来安装液压缸。本发明能通过控制液压缸液压杆的伸缩长度,调整撑杆的整体长度;解决了现有撑杆适用范围受限的问题;同时,提高了撑杆与吊装索具的匹配效率,减少了不同撑杆规格的数量,降低了施工成本。
