Abstract

Provided is a load-adaptive hoisting mechanism, including a bracket and roofs, wherein the roofs are arranged above the bracket, upright columns are arranged between the bracket and the roofs, through holes corresponding to the upright columns are formed in the roofs, the upright columns are arranged in the through holes, and the lower ends of the upright columns are connected with the bracket; springs sleeve the upright columns between the bracket and the roofs; roof pulleys arranged on the side surfaces of the roofs, bracket pulleys arranged on the side surfaces of the bracket, and the side surfaces of the roofs corresponding to the side surfaces of the bracket; a truncated conical roller arranged in the center above the bracket.

First claim

What is claimed is:

1. A load-adaptive hoisting mechanism, comprising: a bracket and roofs, wherein the roofs are arranged above the bracket, upright columns are arranged between the bracket and the roofs, through holes corresponding to the upright columns are formed in the roofs, the upright columns are arranged in the through holes, and the lower ends of the upright columns are connected to the bracket; first springs sleeving the upright columns between the bracket and the roofs; roof pulleys arranged on the side surfaces of the roofs, bracket pulleys arranged on the side surfaces of the bracket, wherein the side surfaces of the roofs correspond to the side surfaces of the bracket; a roller arranged in the center above the bracket and being a truncated conical type, wherein the lower end of the roller is the end with smaller diameter, and is connected to a power input shaft of the hoisting mechanism; the upper part of the roller is provided with tensioning cables, one ends of the tensioning cables are fixed to the upper part of the roller, and the other ends are connected to loads sequentially through the roof pulleys and the bracket pulleys.

2. The load-adaptive hoisting mechanism of claim 1 , wherein four columns are symmetrically arranged on two sides of the roller, and the corresponding bracket and the roofs both adopt symmetrical structures.

3. The load-adaptive hoisting mechanism of claim 2 , wherein two roof pulleys and two bracket pulleys are arranged.

4. The load-adaptive hoisting mechanism of claim 1 , wherein two upright columns are arranged on the same side of the bracket, and the corresponding roof adopts the unilateral structure.

5. The load-adaptive hoisting mechanism of claim 4 , wherein one roof pulley and one bracket pulley are arranged.

6. The load-adaptive hoisting mechanism of claim 4 , wherein a fixing frame is arranged above the roofs, and the upper ends of the upright columns penetrate through the through holes in the roofs and are connected with the fixing frame; and the center of the larger-diameter end of the roller is provided with a roller shaft which is arranged on the fixing frame via a bearing.

7. The load-adaptive hoisting mechanism of claim 1 , wherein the load-adaptive hoisting mechanism adopts a motor as a power source.

8. A load-adaptive hoisting mechanism, used for transmitting torque power, comprising: a bracket and roofs, wherein the roofs are arranged above the bracket, upright columns are arranged between the bracket and the roofs, through holes corresponding to the upright columns are formed in the roofs, the upright columns are arranged in the through holes, and the lower ends of the upright columns are connected with the bracket; first springs sleeving the upright columns between the bracket and the roofs; two roof pulleys arranged on the roofs; a roller is arranged in the center above the bracket, being a truncated conical type, and fixedly mounted on the power input shaft in a sleeving manner, wherein the power input shaft is arranged on the bracket via a bearing; transmission wheels arranged at the lower part of one side on the bracket corresponding to the roof pulleys; tensioning cables arranged between the transmission wheels and the roller, wherein the tensioning cables in the form of a closed ring wind around the two roof pulleys; a cable tensioning mechanism arranged on the tensioning cables between the cable sending side of the roller and the cable winding sides of the transmission wheels when the mechanism works.

9. The load-adaptive hoisting mechanism of claim 8 , wherein the cable tensioning mechanism comprises a cable binding reel and a cable pushing reel, wherein the cable binding reel is fixedly arranged on the bracket, and the cable pushing reel is provided with a second spring; the cable binding reel and the cable pushing reel are respectively arranged on two sides of the tensioning cables; and the second spring is a thrust spring and is arranged on the opposite sides against the corresponding tensioning cable.

10. The load-adaptive hoisting mechanism of claim 9 , wherein four upright columns are symmetrically arranged on two sides of the roller; two roofs, two roof pulleys, two tensioning cables, two transmission wheels and two cable tensioning mechanisms are respectively and symmetrically arranged on two sides of the bracket; the inner side of each of the transmission wheels is coaxially provided with a small bevel gear; the lower part of the bracket is provided with a power output shaft fixedly provided with a large bevel gear in a sleeving manner, and the large bevel gear is meshed with the two small bevel gears respectively.

11. The load-adaptive hoisting mechanism of claim 8 , wherein four upright columns are symmetrically arranged on two sides of the roller; two roofs, two roof pulleys, two tensioning cables, two transmission wheels and two cable tensioning mechanisms are respectively and symmetrically arranged on two sides of the bracket; the inner side of each of the transmission wheels is coaxially provided with a small bevel gear; the lower part of the bracket is provided with a power output shaft fixedly provided with a large bevel gear in a sleeving manner, and the large bevel gear is meshed with the two small bevel gears respectively.
