[0048] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0049] This application provides a rotary elevator for loading and unloading vehicles, see reference. Figures 1 to 18 It includes: equipment base 1, rotating mechanism 2, rotating column 3, lifting mechanism 4, connecting frame 5, and car 6. See attachment. Figure 1 , Figure 2 and Figure 3 .

[0050] The rotating mechanism 2 is disposed on the upper end of the equipment base 1;

[0051] The rotating mechanism 2 includes a slewing bearing 7, a reduction motor 9, and a gear 10. The outer ring of the slewing bearing 7 is connected to the upper end of the equipment base 1, and the inner gear ring of the slewing bearing 7 is connected to the rotating column 3. The gear 10 is mounted on the output shaft of the reduction motor 9 and meshes with the inner gear ring of the slewing bearing 7.

[0052] The lifting mechanism 4 is mounted on the rotating column 3. The lifting mechanism 4 includes a hollow shaft reduction motor 12, a trapezoidal lead screw 13, a trapezoidal lead screw nut 14, a linear guide rail 17, and a linear guide rail slider 20.

[0053] The hollow shaft reduction motor 12 is mounted on the upper end of the rotating column 3. The rotating shaft of the hollow shaft reduction motor 12 is connected to the upper end of the trapezoidal lead screw 13. The lower end of the trapezoidal lead screw 13 extends downward along the length of the rotating column 3. The trapezoidal lead screw nut 14 is sleeved on the trapezoidal lead screw 13 and threadedly connected to the trapezoidal lead screw 13. At least two linear guide rails 17 are provided. The linear guide rails 17 are mounted on the side wall of the rotating column 3 and are arranged parallel to the trapezoidal lead screw 13. The linear guide rail slider 20 is slidably connected to the linear guide rail 17.

[0054] The connecting frame 5 is connected to the linear guide slider 20;

[0055] The side of the car 6 is connected to the connecting frame 5.

[0056] Specifically, the rotary elevator is used in the following scenarios: the equipment is installed indoors to load goods from indoors to outdoor freight cars, or to unload goods from freight cars to indoors. After loading or unloading is complete, the elevator car is rotated indoors, and the roller shutter door next to the equipment can be closed. See attached document. Figure 4 .

[0057] In some embodiments, the upper surface of the equipment base 1 is provided with mounting holes for the slewing bearing 7 and the geared motor mounting seat 8, and the outer ring of the slewing bearing 7 and the bottom surface of the geared motor mounting seat 8 are connected to the equipment base 1 through the mounting holes.

[0058] The geared motor 9 is connected to the equipment base 1 via the geared motor mounting bracket 8.

[0059] Specifically, the equipment base 1 is mainly composed of welded profiles and plates, and serves as the load-bearing component of the entire equipment. (See attached document) Figure 5 and Figure 6 .

[0060] Specifically, the rotating mechanism mainly consists of a slewing bearing, a geared motor, a geared motor mounting base, and gears. The outer ring of the slewing bearing is connected to the equipment base, and the inner gear ring is connected to the rotating column. The bottom surface of the geared motor mounting base is mounted on the equipment base, and the geared motor is mounted on its upper surface. The rotation of the geared motor drives the gears to rotate, which in turn drives the inner gear ring of the slewing bearing to rotate, ultimately rotating the rotating column. See attached diagram. Figure 7 .

[0061] In some embodiments, the rotating column 3 has an internal cavity, and the side wall of the rotating column 3 opposite to the lifting mechanism 4 has an installation and maintenance port, and the installation and maintenance port has a hinged inspection door 21.

[0062] Specifically, the rotating column 3 is mainly constructed from welded sheet metal. The bottom of the rotating column is connected to the slewing bearing, and a lifting mechanism is installed on the side of the rotating column. A lifting counterweight guide is provided inside the column cavity, and an installation and maintenance port is located opposite the installation of the lifting mechanism 4. (See attached document) Figure 8 , Figure 9 , Figure 10 .

[0063] In some embodiments, the lifting mechanism 4 further includes:

[0064] The double-row tapered roller bearing 15 and the mounted bearing 16 are respectively sleeved on the upper and lower ends of the trapezoidal lead screw 13. The double-row tapered roller bearing 15 is disposed on the upper end of the rotating column 3, and the mounted bearing 16 is disposed on the lower end of the rotating column 3.

[0065] In some embodiments, the lifting mechanism 4 further includes:

[0066] The counterweight 18 and the counterweight fixed pulley 19 are provided. The counterweight 18 is disposed in the inner cavity of the rotating column 3, and the counterweight fixed pulley 19 is disposed at the upper end of the rotating column 3. The counterweight connecting belt 22 passes around the counterweight fixed pulley 19 and connects the connecting frame 5 and the counterweight 18 respectively.

[0067] In some embodiments, the counterweight connecting belt 22 is coated with an antistatic coating on both sides to prevent static electricity from being generated between it and the fixed pulley. The lifting counterweight moves up and down in the opposite direction as the connecting frame moves up and down.

[0068] In some embodiments, the trapezoidal lead screw 13 and the trapezoidal lead screw nut 14 have a mechanical self-locking structure, while the hollow shaft geared motor 12 has a brake structure to ensure that there is no risk of cargo falling.

[0069] Specifically, the linear guide slider is connected to the connecting frame 5 for guiding the lifting and lowering of the connecting frame. The hollow shaft geared motor drives the trapezoidal lead screw to rotate, thereby causing the trapezoidal lead screw nut to move up and down. The trapezoidal lead screw nut, connected to the connecting frame, ultimately drives the connecting frame to move up and down. (See attached diagram) Figure 11 , Figure 12 , Figure 13 .

[0070] In some embodiments, the car 6 is welded from profiles and plates, and the sides of the car are bolted to the connecting frame, moving with the movement of the connecting frame. Hinged tilting railings 23 are provided at both ends of the car 6. After the transfer trolley enters the car, the tilting railings close to prevent the transfer trolley from falling out of the car during rotation and lifting, thus preventing a safety accident. A cushioning rubber sponge layer 24 is provided at the bottom of the car 6 to prevent the car from directly impacting the ground when descending to near the ground, thus preventing sparks and potential dust combustion and explosion safety accidents. See Appendix. Figure 14 and Figure 15 .

[0071] This application provides an introduction to the explosion-proof safety features of the rotary elevator equipment:

[0072] 1. The entire equipment is grounded against static electricity: This is the most important part of static electricity protection, as it is used to prevent the harmful effects of static electricity and to discharge it.

[0073] 2. All electrical components used in this equipment, including motors, are explosion-proof. The entire electrical control box is also explosion-proof.

[0074] 3. Ensure that there is no hard mechanical collision between steel and steel throughout the entire equipment.

[0075] 4. The moving parts of the equipment are protected by dustproof seals.

[0076] In some embodiments, the lifting mechanism 4 is surrounded by an upper U-shaped accordion cover 25 and a lower U-shaped accordion cover 26, both made of fireproof cloth. One end of the upper U-shaped accordion cover is connected to the top plate of the rotating column 3 via a flange, and the other end is connected to the upper end of the connecting frame 5 via a flange. One end of the lower U-shaped accordion cover is connected to the upper end of the connecting frame 5 via a flange, and the other end is connected to the bottom plate of the rotating column 3 via a flange. The accordion cover contracts or extends with the movement of the connecting frame. The entire linear guide rail assembly and trapezoidal lead screw are enclosed within the U-shaped accordion cover, significantly improving the isolation between the moving parts and the powder layer. (See attached image) Figure 16 , Figure 17 , Figure 18 .

[0077] In some embodiments, a cover 27 and a first sealing strip 28 are provided on the top of the rotating column 3; a second peripheral sealing strip 11 is provided on the side of the hinged access door to ensure that the inner cavity of the rotating column is isolated from dust.

[0078] Working principle:

[0079] The technical solution in this application is specifically designed based on user needs and scenarios (explosion-proof requirements for powder coating). The rotary elevator equipment is installed indoors to realize the transfer function between the outdoor truck bed and the indoor area. After the transport truck arrives at the designated location at the entrance of the outdoor workshop, the rotary elevator is raised from its initial position and rotated 90° until the elevator car is level with and connected to the transport truck. Then, the goods in the truck bed are manually moved onto the transfer trolley inside the rotary elevator car. The rotary elevator then rotates 90° in the opposite direction and descends to the designated height on the ground. The transfer trolley is then pushed out of the rotary elevator car and placed in the designated location in the workshop. The loading function can be achieved by reversing these actions.

[0080] Note that, unless otherwise explicitly stated, all features disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by alternative features for achieving the same, equivalent, or similar purpose. Therefore, unless explicitly stated otherwise, each disclosed feature is merely one example of a set of equivalent or similar features. Where used, "further," "preferably," "even further," and "more preferably" are simple starting points for describing another embodiment based on the foregoing embodiments, the combination of which with the foregoing embodiments constitutes the complete configuration of another embodiment. Any combination of several "further," "preferably," "even further," or "more preferably" settings following the same embodiment constitutes yet another embodiment.

[0081] In the implementation of functions and steps, the corresponding functions and steps in the various embodiments may occur in a different order than those shown. For example, two consecutive functions and steps may actually be executed or implemented substantially in parallel, and they may sometimes be executed or implemented in reverse order, depending on the functions involved.

[0082] Although this application has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of this application fall within the scope of protection claimed in this application.
