Description

Technical Field

[0001] The utility model relates to the technical field of plate processing, in particular to a multi-layer placement rack. Background Art

[0002] Cement board, as the name implies, is a kind of building flat plate processed and produced with cement as the main raw material. It is a kind of building product between gypsum board and stone, which can be freely cut, drilled and carved. It has become a widely used building material in the construction industry because of its fireproof, waterproof, anti-corrosion, insect-proof and sound-insulating properties that are superior to gypsum board and wood board and its price is much lower than stone. Prestressed floor refers to the application of tensile stress to the stressed steel bars during the production process to prevent the concrete in the tensile part of the board from cracking during operation, while also giving full play to the role of the tensile steel bars and saving steel. Cement boards, prestressed boards, etc. need to be placed on racks for maintenance after production. Since these types of building boards have a certain weight, it is more difficult to place the boards on the racks. For this reason, we propose a multi-layer placement rack. Utility Model Content

[0028] The inner side of the rotating support block 203 is provided with an inclined surface matching with the top end of the top seat 6;

[0029] The upper end of the rotating support block 203 is provided with a receiving groove, and rollers 8 are installed equidistantly in the receiving groove; the rollers 8 are arranged at the upper end of the rotating support block, and the rollers 8 are in contact with the loading tray 3, which is conducive to the sliding separation of the loading tray 3 and the tray support seat 2;

[0030] The side of the frame 1 is also provided with a tray placer for driving the loading tray 3 to rise and fall. The tray placer includes a tray lifting mechanism 5, a top seat 6 and a support block stopper 7. The tray lifting mechanism 5 is installed on the outside of the frame 1. There are two top seats 6, which are respectively placed at the movable ends of the tray lifting mechanism 5. The top seats 6 are located below the loading tray 3 and correspond to the tray support seat 2 one by one. The loading tray 3 with the building board can be raised and lowered by the tray placer, so that the tray is stuck on the upper side of the tray support seat 2, or unloaded from the tray support seat 2, which reduces manual assistance and improves efficiency.

[0031] The tray lifting mechanism 5 includes a nut sliding seat 501, a driving motor 502 and a lead screw 503. The nut sliding seat 501 is slidably arranged on the outer side of the frame 1. The frame 1 is provided with a vertical lead screw 503 and a driving motor 502 whose output end is fixedly connected to the lead screw 503. The lead screw 503 is threadedly matched with a threaded hole of the nut sliding seat 501. In the specific working process of the tray lifting mechanism 5: the driving motor 502 drives the lead screw 503 to rotate, and when the lead screw 503 rotates, it drives the nut sliding seat 501 threadedly matched with it to slide along the vertical direction of the frame 1;

[0032] The support block stopper 7 includes an electric telescopic rod 701 and a push plate 702. A notch is provided on one side of the top of the top seat 6 close to the rotating support block 203, and a push plate 702 is provided at the notch for horizontal sliding. The electric telescopic rod 701 is horizontally fixed at the upper end of the top seat 6, and the telescopic arm of the electric telescopic rod 701 is fixedly connected to the push plate 702.

[0033] A controller is also provided, the input end of the controller is connected to an external power source, and the output end of the controller is electrically connected to the input ends of the drive motor 502 and the electric telescopic rod 701 respectively.

[0034] The working principle of a multi-layer placement rack provided by the utility model is as follows:

[0035] When it is necessary to stack building boards on the frame 1: the building boards are on the loading tray 3 and are transported to the inner bottom of the frame 1 by the transfer trolley. The trolley is moved so that the lower sides of both ends of the loading tray 3 are clamped on the upper side of the top seat 6. The tray lifting mechanism 5 drives the loading tray 3 and the building boards thereon to move upward.

[0036] In the natural state, under the action of the return spring 204 of the tray support seat 2, the rotating support block 203 is in an oblique inner position (such as Figure 4As shown in the position, the loading tray 3 pushes the rotating support block 203 to make it rotate outward around the rotating shaft 202 during the upward movement, and the return spring 204 is compressed at this time; in the process of passing over the tray support seat 2 on the lower side, the push plate 702 of the support block stopper 7 is at the farthest end of the stroke, blocking the rotating support block 203 on the outside of the loading tray 3;

[0037] The tray lifting mechanism 5 drives the loading tray 3 to move upward to the top and then starts to place it. At this time, the loading tray 3 falls on the upper side of the two tray support seats 2, and the push plate 702 shrinks to the closest end of the stroke. At this time, under the action of the return spring 204, the upper end of the rotating support block 203 rotates inward to the lower side of the loading tray 3, thereby supporting the loading tray 3 with the building board. The tray lifting mechanism 5 drives the top seat 6 to descend to the lower side, and the building board is lifted in turn, and fixed on the tray support seat 2 from top to bottom;

[0038] When the cured building panels need to be lowered or lowered from the frame 1, the tray lifting mechanism 5 removes the loading tray 3 from bottom to top in sequence. During this process, the push plate 702 pushes the rotating support block 203 outward to separate the rotating support block 203 from the loading tray 3, and then it can be lowered along with the top seat 6.

[0039] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
