With preventing cover body 4 from rocking.
With reference to as shown in Figure 3-4, lowering or hoisting gear includes upper air intake duct 120, skeleton 207, motor 222, ball screw
216 and ball nut 218, upper air intake duct upper flange 110 is fixedly connected with the lower flange of air intake duct 1, and the lower end of upper air intake duct 120 passes through
Upper flange 203 is arranged on skeleton 207；Upper flange 203 is fixed with motor mount 220, and motor 222 passes through decelerator
Vertically it is fixedly mounted on motor mount 220 with yielding coupling 221, motor 222 can be using direct current generator or alternating current generator.
The output end of motor 222 is connected with ball screw 216；Fall way 209 is provided with skeleton 207, empty set dress in fall way 209
Upper air intake duct 120, and can do along the outer wall of upper air intake duct 120 and vertically move up and down, the lower flange 213 of fall way 209 and cover body
Adpting flange 41 is connected, and on the excircle of fall way 209 telescoping tube upper flange 206 is welded with；Ball nut is fixed with thereon
218, ball screw 216 is connected through telescoping tube upper flange 206 with ball nut 218, forms transmission, and motor 222 is transported
When dynamic, ball screw 216 is driven to rotate, ball nut 218 is driven on cover body 4 so as to drive fall way 206 to move up and down
Lower movement, the automatic arbitrary height for realizing cover body 4 is adjusted.Telescoping tube upper flange 206 is along the circumferential direction gone up and is symmetrically fixed
Multiple guide pin bushings 219 are provided with, the guide rod 217 that can be moved up and down along guide pin bushing 219 is mounted in each guide pin bushing 219, guide rod is about 217
Two ends are fixed on upper flange 203 and lower positioning disk 214, can effectively play the guide effect for moving up and down.
The lower end of skeleton 207 is provided with the lower positioning disk 214 being fixedly connected with fall way 209, and lower positioning disk 214 is along the circumferential direction
On be uniformly and symmetrically distributed multiple centering wheels 215, the rolling surface of each centering wheel 215 acts against the periphery of fall way 209
On so that fall way 209 is more steady when moving.
In order to control and adjusting the stroke that cover body 4 is moved up and down, it is to avoid beyond range of vertical motion and and collide and damage
Equipment, can be realized using following two scheme：When motor 222 is driven using common asynchronous moter, in lower positioning disk 214
Proximity switch 210 is provided with, proximity switch 201 is provided with upper flange 203, by the position for detecting fall way 209, so as to control
The distance that whole cover body 4 is moved up and down is made, this mode can save integral device cost；Motor 222 using stepper motor or
