[0020] like Figure 1As shown, the bracket 2 is slidably mounted on the bracket 1 and can slide along the bracket 1 driven by the driving mechanism 3. One side of the upper bracket 101 and one side of the lower bracket 102 are hinged. When disassembly is required, the latch 106 is pulled out to reverse the upper bracket 101 by 180 degrees, and the upper bracket 101 and the lower bracket 102 are folded together to reduce the occupied space for easy transportation of the lifting device. It is also convenient during installation. Only the upper bracket 101 needs to be reversed and fixed with the latch 106. When the support frame 4 is no longer in use, it can be removed from the bracket 1 for easy storage. When in use, the goods or the trolley are placed on the bracket 2, and the driving mechanism 3 drives the bracket 2 to slide along the bracket 1, so as to transport the goods to a high place for unloading. In this embodiment, according to actual conditions, the bracket 1 can also be used without the support frame 4 and be used against a wall or a high railing of a carriage.

[0021] The driving mechanism 3 includes a first pulley 301, a driving motor 302 and a first traction rope 303. The first pulley 301 is rotatably mounted on the upper bracket 101, and the driving motor 302 is detachably mounted on the lower bracket 102. A winding drum is installed at the output end of the driving motor 302. One end of the first traction rope 303 is connected to the winding drum, and the other end of the first traction rope 303 passes through the first pulley 301 and is connected to the bracket 2.

[0022] like Figure 2 As shown, one end of the first traction rope 302 is hung on the bracket 2, and the driving motor 302 is started. The winding drum 302 on the driving motor 302 rotates to reel in the first traction rope 303, and the first traction rope 303 pulls the bracket 2 to move upward along the support 1.

[0023] Slide grooves 107 are provided on both inner walls of the upper bracket 101 and the lower bracket 102 . A plurality of support rods 201 are provided at the bottom of the bracket 2 . Both ends of the support rods 201 are connected with movable wheels 202 . The movable wheels 202 are arranged in the slide grooves 107 .

[0024] like Figure 1 As shown, when the upper bracket 101 and the lower bracket 102 are in use, the slide groove 107 on the upper bracket 101 and the slide groove 107 on the lower bracket 102 are connected to each other, so that the movable wheel 202 can move from the slide groove 107 of the lower bracket 101 to the slide groove 107 of the lower bracket 102, and the movable wheel 202 moves along the slide groove 107 to drive the cart or cargo on the bracket 2 to slide, and the bracket 2 can slide out along the slide groove 107 of the lower bracket 102, and can slide out of the slide groove 107 when not in use for easy storage.

[0025] The support frame 4 includes an upper support frame 401 and a lower support frame 402. The upper part of the upper support frame 401 is hinged to the upper part of the upper bracket 101 through a pin shaft, and the two sides of the lower part of the upper support frame 401 are connected to the two sides of the lower part of the upper bracket 101 through a connecting rod 403. The upper support frame 401 is mounted on the lower support frame 402, and a plurality of cross bars 404 are fixedly connected to the upper support frame 401. The lower support frame 402 is equipped with a support rod 405, and a second pulley 406 is rotatably installed on the top of the support rod 405. A wire reel 407 is installed at the lower part of the lower support frame 402, and a second traction rope 408 is wound around the wire reel 407. One end of the second traction rope 408 passes through the second pulley 406 and is connected to the cross bar 404 close to the side of the lower support frame 402.

[0026] like Figure 1 As shown, the height of the support frame 4 is determined according to the height to which the goods need to be lifted, that is, the second traction rope 408 is wound by the reel 407, and under the action of the second pulley 406, the cross bar 404 is pulled to drive the upper support frame 401 to move up along the lower support frame 402, and the upper support frame 401 is lifted to a suitable position, and the opening angle of the support frame 4 and the bracket 1 is fixed by the connecting rod 403, wherein both ends of the connecting rod 403 are detachably mounted on the upper support frame 401 and the upper bracket 101 by bolts.

[0027] A short rod 5 is fixedly connected to one side of the lower bracket 102 , and universal wheels 6 are installed on one end of the short rod 5 away from the lower bracket 102 and the bottom of the support frame 4 .

[0028] like Figure 1 As shown, the lifting device can be moved to a suitable position at will through the universal wheels 6.

[0029] The lower part of the upper bracket 101 is a vertical structure, and the upper part of the upper bracket 101 is an arc structure.

[0030] like Figure 1 As shown, the arc-shaped structure portion is used to tip the trolley so that the goods in the trolley can be poured out.

[0031] Principle of use: Before use, the lifting device is installed first. First, the folded upper bracket 101 is opened so that it is on the same plane as the lower bracket 102, and then fixed by the pin 106, and then the drive motor 302 is installed on the lower bracket 102, and then the support frame 4 is installed on the upper part of the upper bracket 101, and the reel 407 is rotated according to the required lifting height to raise the height of the upper support frame 401. After the height adjustment is completed, it is fixed by the connecting rod 403 and transferred to the required place under the action of the universal wheel 6; when in use, the trolley is hung on the bracket 2 and the drive motor 302 is started. The bracket 2 is driven to move up along the bracket 1 through the first pulley 301 and the first traction rope until the goods on the bracket 2 rise to the arc structure of the upper bracket 101. Under the action of the arc structure, the goods in the trolley or the bracket 2 are dumped down, and then the drive motor 302 rotates in the opposite direction to make the bracket 2 slide downward along the slide groove 107.
