Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Embodiment：
Fig. 1 and Fig. 2 are referred to, the utility model provides a kind of technical scheme：A kind of building-construction lifting machine safety device,
It is arranged on including limiter of speed 1, cage hoisting frame 2, tie rod 3 and driving steel wire rope 4, the limiter of speed 1 on cage hoisting frame 2, institute
Stating limiter of speed 1 includes shell 5 and two centrifugal-blocks 6, and the centrifugal-block 6 described in two is be hinged by pull bar 7, and the shell 5 is by interior
Justify shell 8 and cylindrical shell 9 forms, sideboard 10 and fixed dam 11 are installed on the inner circle shell 8, consolidated on the cylindrical shell 9
Dingan County is equipped with cantilevered axle 12, and one end of the tie rod 3 is connected with limiter of speed 1, and the other end is connected with transverse axis 13, the transverse axis 13
It is fixed on cage hoisting frame 2, and the both ends of transverse axis 13 are respectively connected with voussoir 14, one end of the driving steel wire rope 4 is fixed on
