[0038] like Fig.11 As shown, the outer ends of the main limit barrier vertical plates 18 are evenly fixed with control switches 44, and there are four control switches 44. The side ends of the four control switches 44 are fixedly connected with controllers 43, which can ensure that the four control switches 44 operate independently and stably. If one control switch fails, the entire device can still operate stably.

[0039] The first sliding adjustment limit plate 31 and the second sliding adjustment limit plate 38 are slidably clamped on the hoisting and placing platform 7, the bottom end of the main limit barrier vertical plate 18 is fixedly connected to the hoisting and placing platform 7, and the side sliding protection plate 8 is slidably clamped in the sliding adjustment slot 20 through the sliding limit clamping plate 17, which plays a role in sliding limit stability.

[0041] The working principle of embodiment 1 is as follows: the hoisted object is placed on the hoisting placement table 7, and then the second motor 36 is started, the second motor 36 drives a rotating adjustment wheel 35 to rotate, the rotating rotating adjustment wheel 35 can realize synchronous rotation through the synchronous belt 39, the synchronously rotating rotating adjustment wheel 35 can drive the driving adjustment gear plate 32 to rotate synchronously, and the rotating driving adjustment gear plate 32 can synchronously drive the first sliding adjustment limit plate 31 and the second sliding adjustment limit plate 38 to slide on the hoisting placement table 7 through the first moving control gear plate 30 and the second moving control gear plate 37, so as to adjust the objects placed on the hoisting placement table 7. The bottom squeeze limit adjustment of the object allows the hoisted object to be placed centrally on the hoisting platform 7, and the bottom of the object can be clamped and limited. When the bottom of the object is limited, the second electric push rod 29 is started to make the detection auxiliary limit frame 26 rise from the bottom of the hoisting platform 7. The raised detection auxiliary limit frame 26 plays the role of auxiliary barrier limit for the bottom of the object during the hoisting process, and the third laser distance measuring sensor 28 evenly distributed on the detection auxiliary limit frame 26 can detect the distance between the object and the hoisting object in real time during the hoisting process, so as to judge whether the hoisted object is displaced and shaken;

[0042] By starting the symmetrically arranged first motor 10, the driving control gear 13 at the bottom can be driven to rotate through the first motor 10, and then the two driving control gears 13 can be driven to rotate through the driving rod 11. The rotating driving control gear 13 can drive the side sliding protection plate 8 to slide open and close horizontally through the second adjusting control gear plate 12 and the first adjusting control gear plate 9, so that the hoisted objects can be conveniently placed on the hoisting placement table 7, and the objects can be fully protected on all sides during the hoisting process.

The extrusion limit adjustment disk 22 can be used to adjust the extrusion fixed area of ​​the object. The extrusion limiters on both sides of the upper end allow the bottom and top of the article to be limited, making the lifting process safe and stable. The second laser ranging sensor 19 set on the main limit baffle plate 18 and the first laser ranging sensor 16 on the side sliding protection plate 8 can detect whether the article is moving. The symmetrically arranged pressure sensors 24 can also assist in detecting whether the article is stably lifted. When the difference in the extrusion pressure on both sides is too large, it means that the article is tilted. The corresponding side 25 can be controlled to provide strong support to maintain balance. Four control switches 44 are set in this device, and controllers 43 are set at the side ends of the four control switches 44. The four control switches 44 can all operate independently, ensuring that the device can operate stably during lifting and use, ensuring the safety of lifting. The hook-type sensor 3 set can determine the gravity change during lifting, and can assist in adjusting and controlling the lifting speed.

[0045] When implementing this embodiment, when the goods placed on the upper end of the hoisting placement table 7 are relatively small, each third motor 41 is started to drive the side protection support plate 42 to rotate inside the outer end of the fixed installation limit frame 40 to adjust the angle of use, forming a protective barrier device, and when the hoisted larger volume items are detected to be deflected to one side, the side protection support plate 42 at the specified position is rotated outward to open, so as to achieve the ability of balancing and adjustment, and the side protection support plate 42 can be replaced with a protective barrier net according to the needs of use, and the side switch protection device 2 is easy to disassemble and fix as a whole, and can be conveniently disassembled and removed when not in use.
