A support cylinder 103 is fixedly provided on the bottom plate 4, and a first support sliding block 104 is rotatably provided on the output shaft of the support cylinder 103. The safety friction disc 306 is made of rubber material, and anti-skid particles are provided on the safety friction disc 306.

[0034] The present invention discloses a lifting machine, whose working principle is: the personnel or goods to be lifted are transferred to the supporting top plate 101, and the supporting cylinder 103 is started. The supporting cylinder 103 pushes the supporting sliding block 104 to slide. The sliding of the supporting sliding block 104 drives the supporting plate 2 107 to rotate. The rotation of the supporting plate 2 107 makes the supporting top plate 101 slide upward, thereby lifting the personnel or goods.

[0035] like Figure 1 As shown, when the supporting top plate 101 is at the highest point, the elastic potential energy of the return spring 208 pulls the auxiliary link 203 through the auxiliary slide bar 207, and the auxiliary link 203 pulls the auxiliary slide plate 204, so that the auxiliary slide plate 204 slides on the supporting top plate 101 toward the center of the supporting top plate 101, thereby making the auxiliary gear 205 move away from the supporting gear column 102, and at the same time, the elastic potential energy of the return spring 208 is transmitted to the supporting top plate 101 through the auxiliary link 203 and the auxiliary slide plate 204, making the supporting top plate 101 more stable.

[0036] When the device fails, the support top plate 101 falls rapidly. When the support top plate 101 falls downward, under the action of the auxiliary connecting rod 1 202 and the auxiliary connecting rod 203, the auxiliary slide plate 204 slides to the two sides of the support top plate 101 and approaches the support gear column 102. When the auxiliary slide plate 204 slides to the predetermined position, the auxiliary gear 205 contacts and meshes with the support gear column 102, and the support top plate 101 continues to fall. The auxiliary gear 205 rotates to drive the auxiliary shaft 209. The auxiliary shaft 209 rotates to drive the safety rotating shaft 305 to rotate through the safety belt 313. The safety rotating shaft 305 rotates rapidly to drive the safety gravity block 1 307, the safety gravity block 2 308, and the safety movable disk 315 to rotate. When the rotation speed reaches the predetermined value, under the action of centrifugal force, the safety gravity block 1 307 and the safety gravity block 2 308 pull the safety movable disk 31 5 slides in the direction of the safety friction disk 306. At this time, the safety movable disk 315 pushes the safety self-locking rod 301 to slide. The sliding of the safety self-locking rod 301 pushes the safety movable rod 310 to rotate. The rotation of the safety movable rod 310 drives the safety disk 312 to slide, so that the safety disk 312 rubs against the safety friction disk 306, thereby reducing the rotation speed of the safety rotating shaft 305. When the safety disk 312 contacts the safety friction disk 306, the elastic force of the safety spring piece 303 causes the safety locking block 304 and the safety bracket 314 to be stuck. At this time, the safety self-locking rod 301 is locked, and the safety disk 312 is pressed against the safety friction disk 306 to slow down the safety rotating shaft 305, thereby slowing down the auxiliary gear 205. The auxiliary gear 205 rotates and slows down, thereby reducing the speed of the supporting top plate 101 falling process, thereby protecting people or objects on the supporting top plate 101.

[0037] After the fault is eliminated, the maintenance personnel manually push the safety spring 303, causing the safety locking block 304 to rotate and disengage from the safety bracket 314. Under the action of the safety reset spring 302, the safety self-locking rod 301 is reset, thereby causing the safety friction disk 306 to disengage from the safety disk 312 and return to its initial position, thereby preparing for protection against the next possible danger.
