DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following is combined with the attached Figure 1 - Figure 4A further detailed description of the present application is provided.

[0020] Embodiment 1:

[0021] A lifting frame for a refrigeration unit includes a base 1. Above the base 1, a lifting platform 6 is provided. An elevating assembly is arranged between the base 1 and the lifting platform 6. Through the elevating assembly, it is convenient to lift the lifting platform 6, realizing the lifting of the refrigeration unit, thereby facilitating subsequent maintenance. An installation groove 7 adapted to the size of the refrigeration unit is formed on the outer wall of the lifting platform 6. Through the installation groove 7, it is convenient to place the refrigeration unit. Outer grooves 10 are formed at the four corners of the installation groove 7, and sliding rods 11 are fixedly connected to the outer walls of the outer grooves 10. Moving seats 20 are slidably connected to the outer walls of the sliding rods 11. Threaded fixing bolts 13 are threadedly connected to the outer walls of the moving seats 20. By sliding the moving seats 20 along the tracks of the sliding rods 11, it is convenient for the subsequent movement of the right-angle stabilizing frame 8. By rotating the threaded fixing bolts 13, the bottoms of the threaded fixing bolts 13 are in contact with the sliding rods 11, thereby facilitating the fixing of the moving seats 20. A connecting frame 12 is fixedly connected to the outer wall of the moving seat 20, and a right-angle stabilizing frame 8 is fixedly connected to the outer wall of the connecting frame 12, so that the moving seat 20 drives the right-angle stabilizing frame 8 to engage with the base of the refrigeration unit through the connecting frame 12, thereby facilitating the stabilization of the refrigeration unit.

[0022] Referring to Figure 1 and Figure 2 As shown in FIGS.

[0023] Referring to Figure 3, a drive box 9 is fixedly connected to the outer wall of the base 1. Two bidirectional lead screws 2 rotate through the bracket 3 to the inside of the drive box 9 and are fixedly connected with two first bevel gears 17. Two second bevel gears 18 are rotatably connected to the outer wall of the drive box 9. The two second bevel gears 18 are engaged with the two first bevel gears 17. The two second bevel gears 18 are provided with transmission shafts. Through the synchronous and same-direction rotation of the two second bevel gears 18, the two second bevel gears 18 drive the two first bevel gears 17 to rotate synchronously and in the same direction, so as to complete the synchronous drive of the two bidirectional lead screws 2.

[0024] Refer to Figure 3 , a servo motor 19 is fixedly connected to the side outer wall of the drive box 9, and the output shaft of the servo motor 19 is fixedly connected to the two second bevel gears 18. By starting the servo motor 19 through an external power supply, the output shaft of the servo motor 19 drives the two second bevel gears 18 to rotate.

[0025] Refer to Figure 1 , grooves 21 are formed on the outer walls of the base 1 and the lifting platform 6, which is convenient for the maintenance of the refrigeration unit through the grooves 21.

[0026] The implementation principle of a refrigeration unit lifting frame in an embodiment of this application is as follows: First, place the refrigeration unit on the installation groove 7 to ensure that the refrigeration unit is clamped with the installation groove 7. Then move the right-angle stabilizers 8 at the four corners of the base 1. Loosen the fixation of the moving seat 20 by rotating the threaded fixing bolt 13, so that the moving seat 20 moves along the track of the sliding rod 11, ensuring that the moving seat 20 drives the right-angle stabilizers 8 through the connecting frame 12 to engage with the four corners of the base of the refrigeration unit. By rotating the threaded fixing bolt 13, the threaded fixing bolt 13 fixes the moving seat 20 on the sliding rod 11 to realize the stability of the refrigeration unit on the lifting platform 6. Secondly, when performing maintenance and lifting, start the servo motor 19 through an external power switch, so that the output shaft of the servo motor 19 drives the two second bevel gears 18 to rotate synchronously and in the same direction. Thus, the two second bevel gears 18 drive the two first bevel gears 17 to rotate synchronously and in the same direction. Through the synchronous rotation of the two bidirectional lead screws 2, due to the design that the thread opening directions on both sides of the two bidirectional lead screws 2 are opposite, the two bidirectional lead screws 2 drive the driving seats 4 on both sides to move towards each other. Thus, the two driving seats 4 drive the two connecting seats 16 to move synchronously and towards each other along the track of the sliding rail 15 through the lifting frame 5. And due to the cross-hinged design of the lifting frame 5, the lifting frame 5 drives the lifting platform 6 to rise, realizing the lifting of the refrigeration unit and facilitating the subsequent maintenance of the refrigeration unit.

However, those skilled in the art can understand that, without departing from the concept of the present disclosure, various modifications and variations can be made to the above specific embodiments, and various combinations can be made to the various technical features and structures proposed by the present disclosure, without exceeding the protection scope of the present disclosure.
