[0003] The above-mentioned stacking device needs to use a clamping cylinder as a power to drive the clamping frame for clamping and the clamping force needs to be maintained during the lifting process. The clamping cylinder needs to be driven by a hydraulic station, and the hydraulic station consumes electricity when working to maintain the hydraulic energy provided to the clamping cylinder during the lifting process, which will increase the production cost. Therefore, it is necessary to redesign a simple lifting fixture for autoclaved aerated concrete panels to solve the above problems. Summary of the invention

[0018] The simple lifting fixture of the autoclaved aerated concrete slab is composed of a support frame 1 and a clamping frame 2. A plurality of clamping frames 2 are movably installed on both sides of the support frame 1 through pins, so that the clamping frames 2 can clamp the two sides of the autoclaved aerated concrete slab, and the autoclaved aerated concrete slab is clamped and fixed between the clamping frames 2, so that the autoclaved aerated concrete slab can be lifted in the process of pulling the clamping frames 2 upward. A load-bearing beam 3 is arranged above the middle of the support frame 1; the top end of the clamping frame 2 extends above the support frame 1, and the end of the clamping frame 2 extending above the support frame 1 is connected to a connecting rod 4 through a pin, and the end of the connecting rod 4 is connected to the load-bearing beam 3 through a pin. The length of the connecting rod 4 is greater than the distance from the clamping frame 2 to the middle position of the end of the support frame 1. The load-bearing beam 3 is connected to the crane, which can pull the load-bearing beam 3 to move horizontally and up and down. During the translation or up and down process, the load-bearing beam 3 can drive the clamping frame 2 to move horizontally or up and down through the connecting rod 4, thereby driving the autoclaved aerated concrete slab clamped and fixed between the clamping frames 2 to move up and down or translate. Since the length of the connecting rod 4 is greater than the distance between the clamping frame 2 and the middle position of the end of the support frame 1, during the process of the load-bearing beam 3 rising relative to the clamping frame 2, when the load-bearing beam 3 rises from a position lower than the top end of the clamping frame 2 to a position level with the top end of the clamping frame 2, the load-bearing beam 3 can push the top end of the clamping frame 2 to move outward through the connecting rod 4, thereby causing the clamping frame 2 to rotate around the pin connecting the clamping frame 2 and the support frame 1 as the axis, thereby causing the bottom end of the clamping frame 2 to move inward, thereby causing the clamping frame 2 to be clamped and fixed on both sides of the autoclaved aerated concrete slab. During the lifting process of the load-bearing beam 3, the clamping frame 2 offsets the gravity of the autoclaved aerated concrete plate through friction. The greater the gravity of the autoclaved aerated concrete plate, the greater the force between the clamping frame 2 and the load-bearing beam 3 through the connecting rod 4, so that the reaction force of the load-bearing beam 3 on the clamping frame 2 through the connecting rod 4 is greater, and then the clamping force of the clamping frame 2 on the autoclaved aerated concrete plate is greater. When the friction coefficient between the clamping frame 2 and the autoclaved aerated concrete plate is large enough, the clamping frame 2 can completely offset the gravity of the autoclaved aerated concrete plate through friction, and self-locking can be formed between the clamping frame 2 and the autoclaved aerated concrete plate, thereby ensuring the lifting of the autoclaved aerated concrete plate.

[0019] A support plate 5 is provided on the inner side of the bottom end of the clamping frame 2, so that when the clamping frame 2 clamps the autoclaved aerated concrete plate, the support plate 5 is inserted into the bottom of the autoclaved aerated concrete plate to support the autoclaved aerated concrete plate, thereby enhancing the support of the clamping frame 2 for the autoclaved aerated concrete plate, so that the autoclaved aerated concrete plate is not easily separated from the clamping frame 2.

[0020] The two ends of the support frame 1 are respectively provided with limit wheels 6 movably mounted through pins. The two ends of the load-bearing beam 3 are respectively provided with hooks 7 movably mounted through pins, and the hooks 7 are engaged with the limit wheels 6. The function of the hooks 7 is to lock the relative position of the load-bearing beam 3 and the support frame 1 through the hooks 7 and the limit wheels 6, thereby ensuring that the load-bearing beam 3 will not push the clamping frame 2 to move inward through the connecting rod 4 during the process of pulling the load-bearing beam 3 upward, thereby maintaining the open state of the clamping frame 2, so that the clamping frame 2 can be easily separated from the autoclaved aerated concrete board. The limit wheels 6 can rotate, and the rotation of the limit wheels 6 can facilitate the engagement or disengagement of the hooks 7 and the limit wheels 6.

[0021] Guide rings 8 are respectively provided on the clamping frame 2 behind the hook 7. A pull rope 9 is connected to the back of the hook 7 at one end of the load-bearing beam 3, and the end of the pull rope 9 passes through the guide ring 8 and is fixedly connected to the back of the hook 7 at the other end of the load-bearing beam 3. The function of the guide ring 8 is to guide the movement of the pull rope 9 through the guide ring 8. Since the guide ring 8 is provided on the clamping frame 2 behind the hook 7, it can ensure that when the pull rope 9 is pulled in any direction, the pull rope 9 can pull the hook 7 to move in a direction away from the limiting wheel 6 through the guidance of the guide ring 8, thereby ensuring that the hook 7 is separated from the limiting wheel 6.

[0022] Before the simple lifting fixture of the autoclaved aerated concrete slab is lifted, the hook 7 should be engaged with the limiting wheel 6.

[0023] When the simple lifting fixture of the autoclaved aerated concrete slab is lifted, the lifting fixture is transferred to the top of the autoclaved aerated concrete slab to be lifted by the crane. After the transfer is in place, the crane lowers the lifting fixture, and the clamping frame 2 is mounted on both sides of the autoclaved aerated concrete slab, so that the support plate 5 at the bottom end of the clamping frame 2 moves to the bottom of the autoclaved aerated concrete slab. After the clamping frame 2 and the support plate 5 are lowered into place, the pull rope 9 is pulled to disengage the hooks 7 at both ends of the load-bearing beam 3 from the limiting wheels 6 respectively. After the hooks 7 are unhooked, the clamping frame 2 and the support frame 1 move downward under the action of their own gravity, so that the load-bearing beam 3 moves upward relative to the clamping frame 2 and the support frame 1. During the relative upward movement of the load-bearing beam 3, the load-bearing beam 3 pushes the clamping frame 2 to move through the connecting rod 4, so that the clamping frame 2 is clamped on both sides of the autoclaved aerated concrete slab, and the support plate 5 is inserted into the bottom of the autoclaved aerated concrete slab. After the clamping frame 2 is clamped on both sides of the autoclaved aerated concrete plate, the crane pulls up the load-bearing beam 3. In the process of pulling up the load-bearing beam 3, under the action of the pulling force of the crane and the gravity of the autoclaved aerated concrete plate, the clamping frame 2 clamps and fixes the autoclaved aerated concrete plate, so that the load-bearing beam 3 can be pulled up by the connecting rod 4 and the clamping frame 2 in turn, and the autoclaved aerated concrete plate is lifted.

[0024] After the autoclaved aerated concrete slab is hoisted into place, the autoclaved aerated concrete slab is lowered for stacking. After the stacking is completed, the hook 7 is pulled by the pull rope 9 to make the hook 7 rise backward, and the load-bearing beam 3 is lowered again so that the end of the hook 7 moves below the limiting wheel 6. After the hook 7 is lowered, the pull rope 9 is released so that the hook 7 is clamped on the limiting wheel 6. In the process of lowering the load-bearing beam 3, the load-bearing beam 3 pulls the connecting rod 4 by its own gravity, and then pulls the clamping frame 2 to open, and at the same time, the support plate 5 is pulled out from the bottom of the autoclaved aerated concrete slab. After the hook 7 is clamped with the limiting wheel 6, the load-bearing beam 3 is pulled upward, and the load-bearing beam 3 drives the clamping frame 2 upward through the hook 7, the limiting wheel 6, and the support frame 1 in turn, so that the clamping frame 2 is separated from the autoclaved aerated concrete slab, and the stacking is completed.

[0025] The simple lifting fixture of the autoclaved aerated concrete plate can push the clamping frame 2 to automatically retract inward, and the clamping frame 2 can maintain the clamping of the autoclaved aerated concrete plate by the weight of the autoclaved aerated concrete plate. Since the autoclaved aerated concrete plate can be clamped without external force, the energy consumption in the lifting process can be effectively reduced, and the production cost can be greatly reduced. The problem that the existing stacking device needs to be clamped by hydraulic pressure, resulting in energy consumption and increased production cost is solved.
