The invention discloses a derrick track for a foundation-pit-free elevator. The derrick track comprises longitudinal beams and cross beams; fixing grooves are formed in both ends of each cross beam, the cross beams are provided with two in total, one side of each of the two longitudinal beams is positioned at the inner sides of the two fixing grooves, fixing bolts are arranged at the joints of thetwo fixing grooves and the two longitudinal beams, first connecting blocks are arranged at the connecting included angles of the cross beams and the two longitudinal beams, a first locking bolt is arranged at one end of the inner side of each first connecting block, and one end of each first locking bolt penetrates through the inner walls of the first connecting blocks and the longitudinal beams.Compared with the prior art, the derrick track for the foundation-pit-free elevator has the beneficial effects that the first connecting blocks are additionally arranged at the joints of the longitudinal beams and the cross beams, and each first connecting block is in a triangle body structure, so that the stability is high; and reinforcing ribs are arranged on the inner sides of the first connecting blocks, so that the intensity of the first connecting blocks is further improved, the condition of deformation does not appear, and the longitudinal beams and the cross beams are connected more stably.
本发明公开了一种用于无基坑电梯的井架轨道,包括纵梁与横梁,所述横梁两端均开设有固定槽,所述纵梁的数量共设置有两个,两个所述纵梁一侧均处于两个所述固定槽内侧,两个所述固定槽与两个所述纵梁的连接处均设置有固定螺栓,所述横梁与两个所述纵梁连接夹角处设置有第一连接块,所述第一连接块内侧一端设置有第一锁紧螺栓,所述第一锁紧螺栓一端贯穿第一连接块与纵梁的内壁;与现有技术相比,本发明的有益效果是:通过纵梁与横梁连接处加装了第一连接块,第一连接块为三角体结构,稳定性高,通过第一连接块内侧设有加强筋,进一步提高第一连接块的强度,不会产生变形的情况,使纵梁与横梁连接更加稳定。
