[0040] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. The described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0041] like Figures 1-3 As shown, a lifting steel plate unloading device includes a lifting platform 1 and a lifting support 2 arranged vertically and parallel to each other, and a folding bracket assembly 3 is provided between the lifting platform 1 and the lifting support 2.

[0042] The folding bracket assembly 3 includes an inner support arm 301 and an outer support arm 302 that are hinged together to form an X shape. The top end of the inner support arm 301 is hinged to the bottom of the lifting platform 1, and a roller 303 is provided at the bottom end of the inner support arm 301. The roller 303 contacts the roller area 15 provided on the lifting support 2.

[0043] The top end of the outer support arm 302 is movably connected to the bottom of the lifting platform 1, and the bottom end of the outer support arm 302 is hinged to the lifting support 2.

[0044] The inner support arm 301 is equipped with a hydraulic cylinder 7, and the piston end of the hydraulic cylinder 7 is connected to a pull rod 8. The other end of the pull rod 8 is connected to a piston joint 9 provided on the outer support arm 302.

[0045] Working principle:

[0046] like Figure 4 and Figure 5As shown, in this embodiment, when using the lifting steel plate unloading device, it is necessary to first dig out a groove 11 on the bottom surface directly below the discharge rack device 10 to accommodate the device, and to fix the lifting support 2 in a stable manner to ensure that it will not shift during operation.

[0047] The operation of the hydraulic cylinder is controlled by an external system. The piston of the hydraulic cylinder 7 drives the connecting rod 8 to move the outer support arm 302 in the opposite direction to the inner support arm 301, wherein:

[0048] When moving towards each other, the angle between the inner support arm 301 and the outer support arm 302 gradually decreases, thereby driving the lifting platform 1 to rise, and thus being able to stably receive the steel plate released by the material discharge rack device 10 at a higher position.

[0049] When moving in opposite directions, the angle between the inner support arm 301 and the outer support arm 302 gradually increases, thereby driving the lifting platform 1 to descend, which in turn lowers the steel plate to a lower position, making it easier to remove it to the outside via the steel plate pallet trolley.

[0050] like Figure 1 and Figure 2 As shown, the lifting support 2 in this embodiment includes a support frame 201 and a first base plate 202 and a second base plate 203 disposed on the left and right sides of the bottom of the support frame 201. The surface of the first base plate 202 constitutes the roller area 15.

[0051] The roller region 15 is blocked on three sides by the support frame 201, thereby effectively limiting the roller 303.

[0052] like Figure 1 and Figure 2 As shown, as an optimization of the inner support arm 301 and the outer support arm 302 in this embodiment, the inner support arm 301 includes a first inner support arm 306 and a second inner support arm 307 symmetrically arranged, and the outer support arm 302 includes a first outer support arm 308 and a second outer support arm 305 symmetrically arranged. The first inner support arm 306 and the second inner support arm 307, as well as the first outer support arm 308 and the second outer support arm 305, are connected by a connecting plate 304.

[0053] In this embodiment, the inner support arm 301 and the outer support arm 302 are configured as a double support arm structure, which can further increase the strength of the folding bracket assembly 3, so that it can better provide longitudinal support for the lifting platform 1 and the lifting support 2, and thus better withstand the weight of the multi-layer steel plates.

[0054] The two rollers 303 are arranged at the bottom ends of the first inner support arm 306 and the second inner support arm 307, and the bottom ends of the first inner support arm 306 and the second inner support arm 307 can slide in the roller area 15 through the two rollers 303.

[0055] As shown in Figure 1 and Figure 2 In this embodiment, the left end of the bottom of the lifting platform 1 is symmetrically provided with an outer arm hinge seat 4, and the right end of the bottom of the lifting platform 1 is symmetrically provided with an inner support arm hinge seat 5; the two outer arm hinge seats 4 are respectively used for hinging with the top ends of the first outer support arm 308 and the second outer support arm 305; and the two inner support arm hinge seats 5 are respectively used for hinging with the top ends of the first inner support arm 306 and the second inner support arm 307.

[0056] As shown in Figure 2 The first outer support arm 308 and the first inner support arm 306 are provided with a first hinge position 13 at the middle segments, and the second outer support arm 305 and the second inner support arm 307 are provided with a second hinge position 14 at the middle segments, and the first hinge position 13 and the second hinge position 14 are both pin shaft hinges.

[0057] In this embodiment, the first hinge position 13 and the second hinge position 14 are symmetrically arranged with each other, and through this structure, stable hinging between the inner support arm 301 and the outer support arm 302 can be realized.

[0058] The two outer arm hinge seats 4 are respectively provided with a plurality of symmetric pin shaft through holes 401, and each pin shaft through hole 401 is horizontally arranged.

[0059] In this embodiment, through the horizontally arranged pin shaft through holes 401, the intersection position of the top end of the outer support arm 302 and the outer arm hinge seat 4 can be hinged.

[0060] Under this structure, if the top end of the outer support arm 302 is hinged with the two innermost pin shaft through holes 401, the highest lifting position of the device can be improved; and if the top end of the outer support arm 302 is hinged with the two outermost pin shaft through holes 401, the highest lifting position of the device can be reduced.

[0061] Through this structure, the highest position of the device can be freely adjusted.

[0062] As shown in Figure 1As shown, the inner wall of the support frame 201 corresponding to the second bottom plate 203 in the embodiment is symmetrically provided with an outer support arm bottom end hinged seat 6 for hinging the first outer support arm 308 and the second outer support arm 305, and the second bottom plate 203 can effectively protect the joint position and prevent the bottom end of the first outer support arm 308 and the second outer support arm 305 from being affected by the groove 11 ground.

[0063] As shown in the drawings, the oil cylinder 7 is connected with the first inner support arm 306, and the piston joint 9 is connected with the first outer support arm 308. Figure 3

[0064] Specifically, the oil cylinder 7 is hinged with the first inner support arm 306 through a pin shaft via an oil cylinder joint 12, and the piston joint 9 is hinged with the first outer support arm 308 through a pin shaft. In this way, the oil cylinder 7 can always keep horizontal during the working process, thereby avoiding collision with the lifting platform 1 and the lifting support 2.

[0065] The above only describes the embodiments of the utility model, and is not used for limiting the utility model. For those skilled in the art, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.​
