Fig. 2 is schematic diagram when the present invention is in working position in elevator device；
Fig. 3 is the structural schematic diagram of lower mechanical preventing device of elevator in Fig. 1；
Fig. 4 is the schematic diagram of another angle of Fig. 3；
Fig. 5 is the structural schematic diagram of lower mechanical preventing device of elevator in Fig. 2；
Fig. 6 is the schematic diagram of another angle of Fig. 5.
Specific embodiment
The technical scheme of the invention is described in detail through specific implementation examples.
As shown in Figures 1 to 6, lower mechanical preventing device of elevator includes the support column 1 being vertically arranged, connects on support column 1
Rotating arm 2,2 one end of rotating arm hinge 3, hinge 3 has the shaft 30 that extends along the vertical direction of axis, in use, hinge 3 is solid
It is scheduled on mounting plate 4, support column 1 30 can rotate around the shaft, and support column 1 has the working position for being in 9 lower section of carriage and is located at
Inoperative position except 9 planimetric area of carriage.It is fixed with vertical overhanging plate 5 on mounting plate 4, overhanging plate 5 and 3, hinge
In the tow sides of mounting plate 4.First positioning hole 51 and second location hole 52 are offered on overhanging plate 5, the end of rotating arm 2 is set
It is parallel to the positioning plate 21 of overhanging plate, positioning plate 21 is equipped with aperture.When support column is located at working position, first positioning hole 51
Alignment apertures are locked using positioning bolt 6, form the first locking structure, support column is locked in working position；When support column is located at
When inoperative position, 52 alignment apertures of second location hole are locked using positioning bolt 6, form the second locking structure, support column is locked
