[0022] As shown in Figure 2 , lifting mechanism 3 includes first hydraulic cylinder 31, the number of first hydraulic cylinder 31 is four, four first hydraulic cylinders 31 are fixedly equipped at the four corners of base 1, and the output end of first hydraulic cylinder 31 is fixedly connected to the bottom of lifting frame 4, the height position of lifting frame 4 can be adjusted by the action of the output end of first hydraulic cylinder 31, so as to adjust the height position of placing table 6, the middle part of base 1 is fixedly equipped with oil tank 32, the top of oil tank 32 is fixedly equipped with first oil pump 33, oil tank 32 is used to store hydraulic oil, the input end of first oil pump 33 is inserted into oil tank 32, and the output end of first oil pump 33 is connected to the input end of first hydraulic cylinder 31 through a connecting pipe, the output end of first hydraulic cylinder 31 can act by setting first oil pump 33 to supply hydraulic oil from oil tank 32 to first hydraulic cylinder 31.

[0023] As shown in Figure 2As shown in the figure, the top of the lifting frame 4 is equipped with a limiting assembly 7. The rotating shaft 5 can be clamped and fixed by the limiting assembly 7. When the relative rotation between the placing table 6 and the lifting frame 4 is not needed, the placing table 6 can be limited by clamping the rotating shaft 5 by the limiting assembly 7, so as to keep the position of the placing table 6 stable during the brick unloading process.

[0024] The limiting assembly 7 includes a second hydraulic cylinder 71 and a second oil pump 74. The number of the second hydraulic cylinder 71 is two, and the two second hydraulic cylinders 71 are fixed and assembled at the top of the lifting frame 4 in left-right symmetry. The inner cavity side wall of the connecting groove 41 is provided with left-right symmetrically distributed clamping grooves 72. Each clamping groove 72 is equipped with a clamping block 73. The output end of the second hydraulic cylinder 71 penetrates into the clamping groove 72 and is fixedly connected with the side wall of the clamping block 73. The action of the clamping block 73 driven by the second hydraulic cylinder 71 can clamp and fix the side wall of the rotating shaft 5. The clamping block 73 is made of rubber material, which can increase the friction between the clamping block 73 and the side wall of the rotating shaft 5, thereby enhancing the limiting and fixing effect of the rotating shaft 5. The second oil pump 74 is fixedly assembled on the side wall of the oil storage tank 32. The output end of the second oil pump 74 is inserted into the oil storage tank 32. The output end of the second oil pump 74 is connected with the output end of the two second hydraulic cylinders 71 through the connecting pipe.

The first oil pump 33 and the second oil pump 74 are respectively electrically connected with a control switch, which is fixedly assembled on the side wall of the lifting frame 4. The control switch controls the oil supply of the first oil pump 33 and the second oil pump 74.

[0026] As shown in Figure 1 The surface of the placing table 6 is fixedly assembled with a non-slip pad 8. The non-slip pad 8 increases the friction between the bricks and the placing table 6 after the bricks are placed, so as to avoid the bricks from sliding off the surface of the placing table 6 during the movement of the platform.

[0027] As shown in Figure 4 The limiting frame 10 is detachably fixedly assembled at the four corners of the placing table 6 by the fixed bolts 9. The limiting frame 10 further improves the stability of the bricks during the transportation process after the bricks are placed on the placing table 6. The top of the fixed bolt 9 is fixedly connected with a handle ring 11. The handle ring 11 facilitates the screwing of the fixed bolt 9.

[0028] Working principle: as Figure 1 and Figure 5 As shown in the platform in use will be placed neatly in the surface of the placing table 6, and then through the screw fixing bolt 9 for assembly and fixation of the limiting frame 10, in the process of transfer of the stone through the limiting frame 10 to increase the stability of the stone on the surface of the placing table 6, through the universal wheel 2 to move the stone to the designated unloading position after the universal wheel 2 is locked, the overall position of the platform is fixed, then the limiting frame 10 is disassembled and the unloading operation can be carried out, when the workers unload the bricks, according to the actual situation of unloading the bricks, the second hydraulic cylinder 71 is controlled to act, so that the clamping block 73 no longer clamps and fixes the rotating shaft 5, the placing table 6 is rotated, which is convenient for the workers to unload the bricks on the surface of the placing table 6 to the designated position, and at the same time, according to the height of the bricks placed on the surface of the placing table 6 during the unloading process, the height of the lifting frame 4 and the placing table 6 can be adjusted through the lifting mechanism 3. Raising the height of the placing table 6 helps workers to unload the bricks more conveniently, reduces the degree of bending over in the process of unloading the bricks, and thus reduces the labor intensity of the workers.
