[0025] Referring to Figures 1-5 , the embodiment of the present application is proposed, the double-layer car lifting system of the embodiment comprises:

[0026] A main car frame (not shown in the drawing) is provided with a movable car frame 10, the car frame 10 is connected with a lifting mechanism (not shown in the drawing), and the car frame 10 is lifted on the main car frame through the lifting mechanism;

[0027] A lower layer car 20 is installed on the car frame 10 and has a plurality of interval distributed lower conveying rollers 21;

[0028] An upper layer car 30 is installed on the car frame 10 through a first lifting buffer mechanism 40 and located above the lower layer car 20, the upper layer car 30 has a plurality of interval distributed upper conveying rollers 31, and the plurality of lower conveying rollers 21 and the plurality of upper conveying rollers 31 are horizontally staggered, and the lifting buffer mechanism can drive the upper layer car 30 to descend to make the upper conveying rollers 31 and the lower conveying rollers 21 level.

[0029] The lifting mechanism drives the car frame 10 to lift along the main car frame, referring to the drawing, Figure 3 When the lower layer car 20 is level with the external car, the material carried on the lower layer car 20 is sent out to the external car first, referring to the drawing, Figure 4As shown, the first lifting buffer mechanism 40 drives the upper layer of the car 30 to descend to make the upper conveying roller 31 and the lower conveying roller 21 level, and then sends the material carried by the upper layer of the car 30 to the outside car. Figure 5

[0030] The lifting machine is designed with upper and lower double-layer cars. When the lifting machine is used, different articles can be placed on the upper and lower double-layer cars according to the needs. For example, the upper layer of the car 30 is used to place light and high turnover materials, and the lower layer of the car 20 is used to carry heavy and large articles. This facilitates workers to load different types of articles and is beneficial to orderly stacking of different articles. Therefore, the utilization rate of the vertical space in the car frame 10 is improved by the double-layer design of the upper and lower cars 20, which is beneficial to improve the loading capacity of the lifting machine in a single lifting, thereby improving the material turnover speed and meeting the high-yield production demand.

[0031] The lifting mechanism includes a traction sheave installed at the top of the main car frame. The traction machine is equipped with a special frequency conversion motor, which can accurately control the lifting speed of the car and adapt to different conveying conditions. The traction sheave is equipped with a high-strength steel wire rope, one end of which is connected to the top of the car frame 10, the other end of which passes through the traction sheave of the traction machine, and is connected to a counterweight, forming a stable traction system to ensure the stable lifting of the car.

[0032] As shown in the drawings, the lower layer of the car 20 is installed on the car frame 10 through the second lifting buffer mechanism 50. The first lifting buffer mechanism 40 and the second lifting buffer mechanism 50 are both hydraulic machines, which can drive the upper layer of the car 30 to lift and ensure the stability of the lifting process, reducing impact and vibration.

[0033] The upper layer of the car 30 and the lower layer of the car 20 are respectively arranged on opposite sides of the car frame 10, so that the upper conveying roller 31 and the lower conveying roller 21 can be staggered and leveled or staggered up and down under the action of the lifting buffer mechanism.

[0034] The main car frame can be welded by high-strength steel to ensure the overall rigidity. The main car frame is provided with lifting rails on both sides of the car frame 10. The upper layer of the car 30 and the lower layer of the car 20 are respectively provided with lifting guide wheels matched with the lifting rails. The rails are precisely milled and polished, with high surface smoothness, to reduce the friction of the car lifting, prevent the car from running off and shaking, and ensure the stable up and down operation of the car frame 10, which is beneficial to improve the positioning accuracy.

[0035] ​The material of the lifting guide wheel is high-strength polyurethane material, which is wear-resistant and mute, precisely embedded into the lifting track, prevents deviation and shaking when the car runs, and improves positioning accuracy. In the embodiment, the car frame 10 further comprises a connecting rod 11, which is arranged between and connected to the upper car 30 and the lower car 20, and the first lifting buffer mechanism 40 is installed on the connecting rod 11. The connecting rod 11 is arranged between and connected to the upper car 30 and the lower car 20, and both the first lifting buffer mechanism 40 and the second lifting buffer mechanism 50 are installed on the connecting rod 11, so that the upper car 30 and the lower car 20 are connected to each other through the connecting rod 11, the first lifting buffer mechanism 40 and the second lifting buffer mechanism 50, ensuring the structural stability.
