Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] like Figures 1 to 14As shown, a hoist includes a base plate 4, a support part 1, an auxiliary part 2, and a safety part 3. The support part 1 is fixedly mounted on the base plate 4, the auxiliary part 2 is fixedly mounted on the base plate 4, and the safety part 3 is fixedly mounted on the auxiliary part 2.

[0031] A safety rotating shaft 305 is rotatably mounted on the safety bracket 314. A safety movable disc 315 is connected to the safety rotating shaft 305 via a spline. A safety gravity block 1 307 and a safety gravity block 2 308 are fixedly mounted on the safety movable disc 315. The other ends of the safety gravity blocks 1 307 and 2 308 are fixedly mounted on the safety rotating shaft 305. A safety friction disc 306 is fixedly mounted on the safety rotating shaft 305. The safety friction disc 306 is in sliding engagement with the safety disc 312. The safety disc 312 rotates... The safety slider 311 is slidably mounted on the safety movable rod 310. The safety movable rod 310 is slidably engaged with the safety self-locking rod 301. The safety movable rod 310 is rotatably mounted on the safety bracket 314. A safety spring 309 is sleeved on the safety rotating shaft 305. One end of the safety spring 309 is mounted on the safety movable disc 315, and the other end of the safety spring 309 is fixedly mounted on the safety rotating shaft 305. The safety rotating shaft 305 is connected to the auxiliary part 2 through the safety belt 313.

[0032] The auxiliary part 2 includes an auxiliary shaft 209 connected to the safety belt 313. An auxiliary gear 205 is fixedly mounted on the auxiliary shaft 209 and meshes with a support gear column 102. The auxiliary shaft 209 is rotatably mounted on an auxiliary slide plate 204. An auxiliary connecting rod 1 202 and an auxiliary connecting rod 203 are rotatably mounted on the auxiliary slide plate 204. The other ends of the auxiliary connecting rods 1 202 and 203 are rotatably mounted on an auxiliary bracket 201. The auxiliary bracket 201 is fixedly mounted on the base plate 4. An auxiliary rotating block 206 is rotatably mounted on the auxiliary bracket 201. An auxiliary sliding rod 207 is slidably mounted inside the auxiliary rotating block 206. One end of the auxiliary sliding rod 207 is rotatably mounted on the auxiliary connecting rod 203, and the other end of the auxiliary sliding rod 207 is equipped with a return spring 208. One end of the return spring 208 is fixedly mounted on the auxiliary sliding rod 207, and the other end of the return spring 208 is fixedly mounted on the auxiliary rotating block 206.

[0033] A second support plate 107 is rotatably mounted on the top support plate 101. The other end of the second support plate 107 is rotatably mounted on a first support sliding block 104, which is slidably mounted on the bottom plate 4. A second support sliding block 105 is slidably mounted on the top support plate 101. A first support plate 106 is rotatably mounted on the second support sliding block 105. The other end of the first support plate 106 is rotatably mounted on the bottom plate 4. The first support plate 106 is rotatably mounted on the second support plate 107. A support cylinder 103 is fixedly mounted on the bottom plate 4. The first support sliding block 104 is rotatably mounted on the output shaft of the support cylinder 103. The safety friction disc 306 is made of rubber and has anti-slip particles.

[0034] The lifting machine disclosed in this invention works as follows: the personnel or goods to be lifted are transferred to the support top plate 101, the support cylinder 103 is activated, the support cylinder 103 pushes the support sliding block 104 to slide, the support sliding block 104 drives the support plate 107 to rotate, the support plate 107 rotates and causes the support top plate 101 to slide upward, thereby lifting the personnel or goods.

[0035] like Figure 1 As shown, when the supporting top plate 101 is at its highest point, the elastic potential energy of the return spring 208 pulls the auxiliary connecting rod 203 through the auxiliary sliding rod 207. The auxiliary connecting rod 203 pulls the auxiliary sliding plate 204, causing the auxiliary sliding plate 204 to slide towards the center of the supporting top plate 101. This causes the auxiliary gear 205 to move away from the supporting gear column 102. At the same time, the elastic potential energy of the return spring 208 is transferred to the supporting top plate 101 through the auxiliary connecting rod 203 and the auxiliary sliding plate 204, making the supporting top plate 101 more stable.

[0036] When this device malfunctions, the support top plate 101 falls rapidly. As the support top plate 101 falls, the auxiliary sliding plate 204 slides towards both sides of the support top plate 101 and approaches the support gear column 102 under the action of auxiliary connecting rod 1 202 and auxiliary connecting rod 203. When the auxiliary sliding plate 204 slides to the predetermined position, the auxiliary gear 205 contacts and meshes with the support gear column 102. The support top plate 101 continues to fall, and the rotation of the auxiliary gear 205 drives the auxiliary shaft 209. The rotation of the auxiliary shaft 209 drives the safety rotating shaft 305 to rotate through the safety belt 313. The rapid rotation of the safety rotating shaft 305 drives the safety gravity block 1 307, the safety gravity block 2 308, and the safety movable disc 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 disc 315. 5. Slide towards the safety friction disc 306. At this time, the safety movable disc 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 disc 312 to slide, so that the safety disc 312 rubs against the safety friction disc 306, thereby reducing the rotation speed of the safety rotating shaft 305. When the safety disc 312 contacts the safety friction disc 306, the safety locking block 304 and the safety bracket 314 are locked under the elastic force of the safety spring 303. At this time, the safety self-locking rod 301 is locked. The safety disc 312 is pressed against the safety friction disc 306, which slows down the safety rotating shaft 305, thereby slowing down the auxiliary gear 205. The rotation of the auxiliary gear 205 slows down, thereby reducing the speed of the support top plate 101 during the fall, thus achieving the protection of people or objects on the support top plate 101.

[0037] After troubleshooting, 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 resets, thereby causing the safety friction disc 306 to disengage from the safety disc 312 and return to its initial position, thus preparing for the next possible danger.
