[0036] In the above, the tilting support plate 5 is arranged on the main bearing plate 1. Further, the bottom surface of the tilting support plate 5 is provided with an inner support foot 18.

[0037] In the above, side baffles 6 are vertically installed on the opposite side edges of the main bearing plate 1, and there are second mounting holes 8 and first mounting holes 9 on the side baffles 6. Correspondingly, there is a third mounting hole 13 on the upper end of the auxiliary bearing frame 16. The transverse tie rod 7 is passed through the second mounting holes 8 on the two sides, and the pull bar 10 is connected between the first mounting hole 9 and the third mounting hole 13.

[0038] In the above description, the auxiliary support plate 14 is installed in the middle of the auxiliary support frame 16 .

[0039] In the above, a locking structure is installed on the hinge seat 17.

[0040] In the embodiment of the utility model, the auxiliary pull frame 3 and the main pull frame 11 adopt a convenient plug-in installation structure.

[0041] In the embodiment of the utility model, a locking structure is installed on the first load-bearing wheel 4 and the second load-bearing wheel 15 .

[0042] Preferably, a counterweight device is installed on the auxiliary pulling frame 3 or the main pulling frame 11 .

[0043] Preferably, the tilting support plate 5, the side baffle plate 6, the transverse tie rod 7 and the pulling bar 10 all adopt a convenient disassembly and assembly structure.

[0044] Preferably, the main load-bearing plate 1, the tilting support plate 5, the auxiliary support plate 14, the auxiliary load-bearing frame 16, and the inner support foot 18 are all made of heavy-load anti-corrosion materials; the side baffle 6, the transverse tie rod 7, and the pull bar 10 can be a rigid structure or a flexible structure; the first load-bearing wheel 4, the second load-bearing wheel 15, and the articulated seat 17 are all made of wear-resistant heavy-load anti-corrosion bearings.

[0045] In the embodiment of the utility model, the auxiliary support frame 16 and the main support plate 1 can be turned over and folded against each other for easy storage.

[0046] The implementation principle of this embodiment is: when it is necessary to feed workpieces and tooling, according to the structural characteristics and dead weight of the workpieces and tooling, they are stacked one by one horizontally or vertically on the tilting support plate 5, and leaned against the auxiliary support plate 14 and the auxiliary bearing frame 16. In order to keep the adjustable stacking frame stable and not overturned, a counterweight device is installed on the auxiliary pull frame 3; then, according to the stacking posture of the workpieces and tooling on the tilting support plate 5, the pull strips 10 and the horizontal pull rods 7 are connected and installed at appropriate positions to clamp and fix the stacked workpieces and tooling relatively; then, according to the needs of further processing or storage and transportation, either the main pull rod 12 is directly pushed and pulled by hand to move under the rolling support of the first bearing wheel 4, or the counterweight device originally installed on the auxiliary pull frame 3 is transferred to the main pull frame 11; then the material is pried with an auxiliary lever that is easy to find. Insert the tilting support plate 5, tilt the tilting support plate 5 and the workpiece and tooling as a whole, so that the tilting support plate 5 and the auxiliary bearing frame 16 are flipped with the hinge seat 17 as the fulcrum, and the auxiliary bearing frame 16 drives the main bearing plate 1 to flip until the auxiliary bearing frame 16 lands on the ground with the second bearing wheel 15 for support. In this process, due to the clamping effect of the side baffle 6, the transverse tie rod 7 and the pulling bar 10, the workpiece and tooling are easy to keep stable during the flipping process. At this time, the auxiliary support plate 14 bears the necessary supporting load; subsequently, when the workpiece and tooling need to be taken, the side baffle 6, the transverse tie rod 7 and the pulling bar 10 are first disassembled and opened.

[0047] In the embodiment of the utility model, an inner support leg 18 is provided. On the one hand, it is beneficial to keep the workpieces and tooling clean. On the other hand, when the connection between the tilting support plate 5 and the hinged seat 17 is released, the forklift's plug plate can be inserted under the tilting support plate 5 to move and transfer the workpieces and tooling on the adjustable stacking rack as a whole.

[0048] Based on the above embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention, so as to avoid exhaustively listing all implementation methods that are unnecessary and impossible to list comprehensively.
