A group of inclined cables 6 are fixedly connected between the bottom end of the wire rope 4 and the fixed rod 7, and the cables 6, the wire rope 4 and the fixed rod 7 form a right-angle triangle structure;
[0026] Specifically, Figure 1 and Figure 2 As shown, the lifting device drives the driving shaft 21 to rotate through a group of servo motors 20. The driving shaft 21 rotates a fixed number of circles, and the active winch disc 3 rotates accordingly, and the driven winch discs 5 on the left and right sides are driven to rotate through the wire rope 4. When the driving shaft 21 rotates forward, the lifting shelf 16 is lifted, and when the driven shaft 22 rotates reversely, the lifting shelf 16 is lowered. The lifting and lowering is achieved by the linkage of a group of motors and multiple groups of winch discs.
[0027] Embodiment 2: Four groups of columns 18 are vertically arranged on the inner wall of the gantry 1, and the outer side of the columns 18 is equipped with a guide rail 19, and the lifting seat 10 is sleeved on the outer side of the guide rail 19 for movement. The four groups of bracket side walls of the gantry 1 are respectively provided with tracks 9, and the lifting seat 10 is equipped with two groups of pulleys 8 on the side close to the track 9, and the pulleys 8 are embedded in the track 9 and form a rolling connection with the track 9;
[0028] Specifically, Figure 1 and Figure 4As shown, when the lifting shelf 16 is lifted or lowered, the pulley 8 on one side of the lifting seat 10 is embedded in the track 9 on the inner wall of the gantry 1 and rolls upward or downward, ensuring that the entire lifting shelf 16 is lifted and lowered smoothly, while converting the moving friction into rolling friction, reducing friction loss and improving the smoothness of lifting.
[0029] Embodiment 3: A stacking rack 17 is placed on the top of the lifting shelf 16, and a supporting plate 11 is arranged below the lifting shelf 16. A group of supporting legs 24 are hinged at the four corners of the bottom end of the supporting plate 11, and the bottom ends of the supporting legs 24 are respectively sleeved with spring seats 14. Strong springs 25 are fixedly connected between the bottom end of the spring seat 14 and the top end of the supporting legs 24. An inner groove 23 is opened inside the supporting plate 11, and a removable loading and unloading plate 12 is assembled in the inner groove 23. A group of handles 13 are installed on both sides of the bottom end of the loading and unloading plate 12. When the loading and unloading plate 12 is fully pulled out, it is tilted and supported on the ground;
[0030] Specifically, Figure 1 , Figure 3 and Figure 4 As shown, when the lifting shelf 16 is lowered as a whole, its bottom first touches the supporting plate 11, and the four sets of supporting legs 24 are squeezed, applying vertical force to the spring seat 14 below, so that the supporting plate 11 is compressed by the internal strong spring 25 to realize the falling of the supporting plate 11, and the loading and unloading plates 12 are pulled out from the inner groove 23, and the handle 13 is supported on the ground.

[0031] Working principle: beer bottles are placed on the stacking rack 17 and placed on the lifting shelf 16. A set of servo motors 20 drives the driving shaft 21 to rotate. The driving shaft 21 rotates a fixed number of circles, and the active winch disc 3 rotates accordingly. The driven winch discs 5 on the left and right sides are driven to rotate through the wire rope 4. When the driving shaft 21 rotates forward, the lifting shelf 16 is lifted, and when the driven shaft 22 is reversed, the lifting shelf 16 is lowered. The lifting is achieved by a set of motors and multiple sets of winch discs. When the lifting shelf 16 is lifted or lowered, the pulley 8 on one side of the lifting seat 10 is embedded in the track 9 on the inner wall of the gantry 1 and rolls up or down to ensure that the entire lifting shelf 16 is in a flat position. The lifting and lowering can be stabilized, and the moving friction force is converted into rolling friction force, which reduces friction loss and improves the lifting smoothness. When the lifting shelf 16 is lowered as a whole, its bottom touches the supporting plate 11 first, and the four sets of supporting feet 24 are squeezed, and a vertical force is applied to the spring seat 14 below, so that the supporting plate 11 is compressed by the internal strong spring 25 to realize the falling of the supporting plate 11, and the loading and unloading plates 12 are pulled out from the inner groove 23, and the handle 13 is supported on the ground. The loading and unloading plates 12 are tilted at a certain angle to facilitate the loading and unloading of goods. When the lifting shelf 16 is lifted, the strong spring 25 is extended and reset again. This structure not only reduces the impact force of the lifting shelf 16 landing, but also facilitates unloading.
