The hollow bearing is arranged to limit the outer gear ring 5, improving the stability of the outer gear ring 5 during rotation. As an embodiment of the present application, the lead screw sliding table 113 is provided in two groups, and the two groups of lead screw sliding tables 113 are respectively located above the left side and below the right side of the plug-in arm type elevator body 1. The adjusting assembly 11 also has a spring connected to one side of the transmission disc 112, and the other end of the spring is connected with the inner wall of the groove of the inner ring 4. The transmission disc 112 is slidably connected with a guide rod, and the guide rod is connected with the groove of the inner ring 4 and passes through the hole formed in the center of the spring.

By setting the two groups of pressing rods, the goods can be limited up and down, reducing the shaking of the goods during lifting and conveying.

[0023] Working principle: first, when the goods need to be conveyed, the plug-in arm type elevator body 1 is started, the plug-in arm type elevator body 1 works, the inner chain slider drives the mounting frame 2 to rise, the movement of the mounting frame 2 drives the support frame 7 to move, the movement of the support frame 7 lifts the goods and separates them from the conveying belt. The mounting frame 2 will also drive the outer gear ring 5 to move during the rising process. The outer gear ring 5 will mesh with the rack of the lead screw sliding table 113 during the rising process and then rotate. The rotation of the outer gear ring 5 drives the semicircular protrusion 6 to rotate. The rotation of the semicircular protrusion 6 drives the inclined block 13 to rotate. The rotation of the inclined block 13 drives the inner ring 4 to rotate. The rotation of the inner ring 4 drives the rotating rod 3 to rotate. The rotating rod 3 rotates under the influence of the synchronous belt and drives the first threaded rod 8 to rotate. Since the first threaded rod 8 is in threaded connection with the sliding frame 9, and the sliding frame 9 is in sliding connection with the support frame 7, the first threaded rod 8 can drive the sliding frame 9 to move horizontally to the side of the mounting frame 2 under the influence of the thread during rotation. The sliding frame 9 will drive the limiting rod 10 to move during the movement process. Since the guide wheels 14 on both sides of the limiting rod 10 are embedded in the guide groove of the support frame 7, the limiting rod 10 will also move upward during the horizontal movement process. The automatic expansion of the limiting rod 10 is completed. The horizontal movement of the limiting rod 10 will gradually fit to the goods, calibrate and limit the position of the goods; Secondly, the rotating rod 3 will also drive the first bevel gear 121 to rotate during the rotation process. Since the first bevel gear 121 is in meshing connection with the second bevel gear 123, the rotation of the first bevel gear 121 will drive the second bevel gear 123 to rotate. The rotation of the second bevel gear 123 drives the second threaded rod 122 to rotate. Since the limiting frame 124 is in threaded connection with the second threaded rod 122, and the limiting frame 124 is in sliding connection with the mounting frame 2, the rotation of the second threaded rod 122 will drive the limiting frame 124 to move downward. The downward movement of the limiting frame 124 limits the upper part of the goods. By cooperating the limiting frame 124 with the limiting rod 10, the goods are limited, reducing the shaking of the goods during the rising process; Then, the outer gear ring 5 rises to the position of the first group of inclined plates 111, the inclined surface of the transmission disc 112 will be in contact with the inclined plate 111 and then move, the transmission disc 112 moves horizontally to push the inclined block 13 to move, the inclined block 13 moves away from the semicircular block 6, so that the outer gear ring 5 rotates and cannot drive the rotating rod 3 to rotate, thereby limiting the movement distance of the limiting rod 10 and the limiting frame 124, avoiding the situation that the limiting rod 10 and the limiting frame 124 extrude and damage the goods, the transmission disc 112 will be separated from the first group of inclined plates 111 during vertical movement, the spring in the groove of the inner ring 4 will push the transmission disc 112 to return to the initial position, since the inclined block 13 and the semicircular block 6 are both inclined surfaces, the inclined block 13 will re-enter the gap of the semicircular block 6 under the action of the spring, when the rotating rod 3 moves to the position of the second group of lead screw slides 113, the outer gear ring 5 will mesh with the gear outside the second group of lead screw slides 113 and rotate in the opposite direction, the outer gear ring 5 rotates in the opposite direction so that the limiting rod 10 and the limiting frame 124 are separated from the goods, thereby releasing the limiting of the goods, the goods can be conveyed through the conveying structure above the plug-in arm type elevator body 1. Finally, when it is necessary to adjust the movement distance of the limiting rod 10, the lead screw slide 113 is started, the lead screw slide 113 drives the inclined plate 111 to move vertically, the position of the lead screw slide 113 is adjusted, thereby adjusting the movement distance of the limiting rod 10 and the limiting frame 124, so that different size goods can be limited.

[0024] Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can modify the technical solutions described in the foregoing embodiments, or make equivalent replacements to part of the technical features, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
