[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-4 The utility model provides a technical solution: a cargo anti-falling mechanism for a lift, comprising:

[0026] A lift body 1 and a lifting frame 2 arranged on the surface of the lift body 1;

[0027] A fence 3 is installed on the top of the lifting frame 2 to prevent the goods from falling off;

[0028] An elastic member 4 for preventing cargo from falling is provided at the bottom of the lift body 1;

[0029] The fence member 3 includes a frame 31 fixedly mounted on the top of the lifting frame 2, with swing plates 32 hinged on both sides of the frame 31, two hooks 33 fixedly mounted on the top of the two swing rods, and a driving member 30 for rotating and storing the two swing plates 32 installed on the surface of the frame 31.

[0030] The driving member 30 includes two motors 301 fixedly mounted inside a frame 31. A rotating rod 302 is mounted on the output end of each motor 301. Two driving wheels 303 are fixedly mounted on the surface of the rotating rod 302. A storage rope 304 is fixedly mounted on the top of each driving wheel 303 and the bottom of the other driving wheel 303. The other end of the storage rope 304 is fixedly mounted on the surface of a hook 33.

[0031] In this embodiment, the goods are placed on the frame 31, and the two motors 301 are started to drive the rotating rod 302 to rotate. The rotating rod 302 drives the two driving wheels 303 on the surface to rotate, and the surface of the driving wheel 303 is fixedly installed with a storage rope 304, which drives the storage rope 304 to move, thereby pulling the two swing plates 32 to rotate for storage, and preventing the goods from falling off the frame 31. The two motors 301 are synchronous servo motors 301, and on the same rotating rod 302, one end of the storage rope 304 is fixedly installed on the top of one driving wheel 303, and another end of the storage rope 304 is fixedly installed on the bottom of the other driving wheel 303. As the two driving wheels 303 rotate, it is sufficient to achieve the simultaneous movement of the two storage ropes 304 to adjust the rotation of the swing plate 32;

[0032] The servo motor 301 is a closed-loop control system capable of very precise control of position, speed, and acceleration. A controller receives commands from a host computer and precisely controls the movement of the servo motor 301. For synchronous applications, the controller can simultaneously process control commands for both motors 301, ensuring they operate at the same speed, position, or acceleration, achieving synchronization between the two servo motors 301.

[0033] The frame 31 is provided with a roller member 5 for limiting and guiding the storage rope 304. The roller member 5 includes two rods 51 rotatably mounted on the frame 31. Auxiliary wheels 52 are fixedly mounted on the surfaces of the two rods 51. The storage rope 304 is arranged between adjacent sides of the two auxiliary wheels 52.

[0034] Specifically, two auxiliary wheels 52 are provided at the top and bottom of the storage rope 304 to serve as a limit guide for the movement of the storage rope 304 .

[0035] In order to prevent the storage rope 304 from easily falling off the auxiliary wheel 52, an annular reserved groove 6 is provided for placing the storage rope 304. The surface of the auxiliary wheel 52 is provided with an annular reserved groove 6 for the movement of the storage rope 304.

[0036] The elastic member 4 includes two long plates 41 fixedly mounted inside the elevator body 1. Anti-fall frames 42 are hingedly connected to opposite sides of the two long plates 41. Anti-fall nets 43 are installed inside the two anti-fall frames 42.

[0037] Among them, anti-fall frames 42 with anti-fall nets 43 are installed on both sides of the bottom of the elevator body 1, which can have a buffering effect on falling tools and protect the tools.

[0038] The bottoms of the two anti-fall frames 42 are hinged with two upper seats 11, and the bottoms of the two upper seats 11 are rotatably mounted with mounting cylinders 7. One side of the two long plates 41 is hinged with two lower seats 8, and the tops of the two lower seats 8 are rotatably mounted with threaded rods 9, and the tops of the threaded rods 9 are mounted with the internal threads of the mounting cylinders 7.

[0039] Specifically, by adjusting the threaded rod 9 to swing on the lower seat 8, and the mounting tube 7 to swing on the upper seat 11, and installing the threaded rod 9 and the internal thread of the mounting tube 7, the anti-fall frame 42 is supported and lifted, and the anti-fall frame 42 can also be stored when not in use.

[0040] In order to facilitate the pulling of the two swings, a metal handle is set on the surface of the swing plate 32, which also serves to enhance the counterweight to prevent the swing plate 32 from being unable to fall and rotate naturally. A handle 10 is fixedly installed at the bottom of the two swing plates 32, and both handles 10 are set as metal handles 10.

[0041] The present invention places goods on the frame 31, starts the two motors 301 to drive the rotating rod 302 to rotate, and the rotating rod 302 drives the two driving wheels 303 on the surface to rotate, and the surface of the driving wheel 303 is fixedly installed with a storage rope 304, driving the storage rope 304 to move, thereby pulling the two swing plates 32 to rotate for storage, and preventing the goods on the frame 31 from falling off. The two motors 301 are synchronous servo motors 301, and one end of the storage rope 304 is fixedly installed on the top of one driving wheel 303 on the same rotating rod 302, and the other end of the storage rope 304 is fixedly installed on the bottom of the other driving wheel 303. With the rotation of the two driving wheels 303, it is sufficient to achieve the simultaneous movement of the two storage ropes 304 to adjust the rotation of the swing plate 32, by adjusting the threaded rod 9 to swing on the lower seat 8, and the mounting cylinder 7 to swing on the upper seat 11, and the threaded rod 9 is installed with the internal thread of the mounting cylinder 7 to support and lift the anti-fall frame 42, and the anti-fall frame 42 can also be stored when not in use.

[0042] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
