Detailed description of the invention
Below, by reference to the accompanying drawings the utility model is described in detail.
As shown in Figures 1 to 5, the present embodiment provides a kind of elevator vertical lift device, and this device comprises: motor (not identifying in figure), drive wheel (not identifying in figure), drive link 1, spiral lifting assembly 2 and track nut pipe 3.
Wherein, be provided with on slip bolt 22 surfaces of spiral lifting assembly 2 corresponding with spiral slide 31 on track nut pipe 3 inwalls can intermeshing spiral slide 23, spiral lifting assembly 2 is embedded in track nut pipe 3, drive link 1 end is provided with the first crowngear 11, this crowngear 11 engages with the second crowngear 24 that is arranged on slip bolt 22 ends in spiral lifting assembly 2, to drive slip bolt 22 along its axle rotation, the axle 21 of slip bolt 22 with for spiral lifting assembly 2 is connected with the fixation kit 4 of being fixed by lifting thing, when electric machine rotation, pass through drive wheel, drive link 1 and the first crowngear 11 are passed to the second crowngear 24 by power and are driven slip bolt 22 to rotate, drive spiral lifting assembly 2 along track nut screwed pipe 3 spiral vertical lifts.
When work, driven by motor drive wheel rotates, and by drive link 1, power is passed to the first crowngear 11, the first crowngears 11 and drive the second crowngear 24 to rotate, and then drives spiral lifting assembly 2 along track nut pipe 3 spiral vertical lifts.
