The invention relates to the technical field of floor derricks, in particular to an adjustable telescopic floor derrick device suitable for narrow space, which comprises a plurality of first standard knots, a plurality of second standard knots and two conical tables, the plurality of first standard knots are vertically fixed to form an outer derrick, and the plurality of second standard knots are vertically fixed with connecting blocks at intervals; the second standard knots and the connecting blocks jointly form an inner holding pole, the outer holding pole is arranged on the outer side of the inner holding pole in a sleeving mode, one conical table is fixed to the top end of the outer holding pole, and the other conical table is fixed to the bottom end of the inner holding pole. By arranging the inner holding pole and the outer holding pole, the outer holding pole can slide on the outer side of the inner holding pole, so that the whole assembled holding pole can be shrunk and extended, the whole holding pole is in a shrunk state before the holding pole stands up, at the moment, the whole holding pole is short, and the needed standing construction space is small; and therefore, the assembled derrick can be erected integrally in a narrow space.

    本发明涉及落地抱杆技术领域,尤其是一种适用于狭小空间的可调节伸缩落地抱杆装置,包括若干个第一标准节、若干个第二标准节和两个锥形台,若干个第一标准节竖直固定组成外抱杆,若干个第二标准节竖向间隔固定有连接块,若干个第二标准节和若干个连接块共同组成内抱杆,外抱杆套设在内抱杆的外侧,其中一个锥形台固定在外抱杆的顶端,另一个锥形台固定在内抱杆的底端。本发明通过设置内抱杆和外抱杆,使外抱杆能在内抱杆的外侧进行滑动,使得组装完成后的抱杆整体,能进行收缩和伸长,在抱杆起立前,使抱杆整体处于收缩状态,此时抱杆整体长度较短,需要的起立施工空间较小,进而有利于在狭小空间内对组装完成的抱杆整体进行起立。
