[0022] The present utility model will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0023] As Figure 1 shown, the high-efficiency multi-stage elevator provided by an embodiment of the present utility model on the one hand includes a base 6, a first lifting part and a second lifting part. Both the first lifting part and the second lifting part include a conveyor 3, a driving structure 4 and a counterweight device 5. The first lifting part further includes a first bracket 1, and the second lifting part includes a second bracket 2. The height of the first bracket 1 is higher than that of the second bracket 2. The first bracket 1 and the second bracket 2 are installed side by side on the base 6. Two conveyors 3 are respectively installed in the middle of the first bracket 1 and the second bracket 2. The driving structures 4 are respectively fixedly installed on the tops of the first bracket 1 and the second bracket 2. The counterweight devices 5 are respectively arranged in the rectangular tubes on both sides of the first bracket 1 and the second bracket 2. The power output end of the driving structure 4 is connected to a chain. One end of the chain is connected to the conveyor 3, and the other end is connected to the counterweight device 5.

[0024] In this application, when in use, the glass products to be transported are placed on the conveyor of the second bracket. The driving structure of the second bracket drives the conveyor to move upward, and the counterweight device moves downward accordingly. At this time, the glass products are lifted to the highest point. At this time, the conveyor on the second bracket is flush with the conveyor on the first bracket. At this time, the glass products are transported to the conveyor on the first bracket, and the driving mechanism of the first bracket continues to lift, realizing the multi-stage lifting and transportation of the glass products.

[0025] As Figure 3 shown, the driving structure 4 includes a driving motor 401, a cross bar 402 and a driving sprocket 403. The driving motor 401 is installed on the cross bar 402. The cross bar 402 is fixedly installed on the tops of the first bracket 1 and the second bracket 2. A driving sprocket 403 is respectively arranged at both ends of the cross bar 402. The power output end of the driving motor 401 is connected to the driving sprocket 403. The driving sprocket 403 meshes with the chain. One end of the chain is connected to the conveyor 3, and the other end is connected to the counterweight device 5. The driving structure 4 further includes a safety rope wheel 404. The safety rope wheel 404 is installed outside the driving sprocket 403. The safety rope wheel 404 is connected to a safety rope. One end of the safety rope is connected to the conveyor 3, and the other end is connected to the counterweight device 5.

[0026] When lifting, the driving motor drives the driving sprockets at both ends of the crossbar to rotate. The chains meshing with the sprockets move up and down, and the conveyor and the counterweight device fixed on the chains also move up and down accordingly. By balancing the force on the driving sprockets with the counterweight, the stability of the bracket is improved. This application also provides a safety rope wheel. The safety rope is a steel wire rope, and both ends of the steel wire rope are also connected to the conveyor and the counterweight device. When the chain suddenly breaks, the safety rope can provide backup tension to prevent the conveyor from falling.

[0027] As Figure 5 shown, the counterweight device 5 is provided with a slider 501. The slider 501 is made of nylon. When the counterweight structure moves up and down in the rectangular tube, the slider can prevent the counterweight structure from rubbing against the rectangular tube and damaging the equipment.

[0028] As Figure 4 shown, a guide tube 301 is provided outside the rectangular tubes on one side of the first bracket 1 and the second bracket 2. The conveyor 3 includes a frame 302 and a lateral driving device 303. A lateral driving device 303 is provided in the middle of the frame 302. Guide structures are provided at both ends of the frame 302. The guide structures roll up and down along the guide tube 301. As Figure 6 shown, the guide structure includes a base 3031, two longitudinal rollers 3032 provided at both ends of the base 3031, and a transverse roller 3033 provided above the longitudinal rollers. In this application, the lateral driving device of the conveyor can be a lateral driving motor, a lateral wheel, and a lateral conveyor belt. When it is necessary to horizontally transport glass products, the lateral driving motor drives the lateral wheel to rotate, and the glass products on the lateral conveyor belt are transported horizontally. When lifting, the upper and lower longitudinal rollers of the guide structure roll along the guide tube, and at the same time, the transverse roller 3033 is in lateral contact with the guide tube, so that the conveyor is in close contact with the guide tube when lifting.

[0029] Obviously, the above embodiments are only examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
