Description

Technical Field

[0002] Concrete slabs refer to a type of plate-like concrete product commonly used in the construction field. They are usually used in floors, wall panels, roofs and other structures. Concrete slabs are widely used in various types of building structures in the construction industry, such as residential buildings, commercial buildings, industrial plants, bridges, tunnels, etc. They are an important building material. After production, concrete slabs are generally stored in stacks, but concrete slabs are heavy and not convenient for stacking at high positions.

A stacking device for concrete slab production includes a bottom plate, and the bottom four corners of the bottom plate are fixed with feet, wheels are fixed under the feet, an upper plate is fixed above the bottom plate, a support plate is arranged on one side of the upper plate, a plurality of plate sliding holes are provided on one side of the support plate, a plurality of ball bearings are rotatably connected in the plate sliding holes, a sliding hole is provided on the upper plate, a slide plate is fixed on one side of the support plate, one end of the slide plate passes through the sliding hole and extends outward, and bearings are fixed on both side walls of the sliding hole. The stacking device places the concrete slabs to be stacked on the support plate, and the rotating mechanism can drive the threaded rod to rotate, and the rotation of the threaded rod can drive the support plate to move upward. When the support plate moves to a suitable position, the electric telescopic rod is activated to push the concrete slab down from the top of the support plate through the baffle, so that stacking can be performed.

[0037] Reference Figure 1 , Figure 3 The buffer assembly includes a hollow rod 61, a circular hole 601 is opened on the right surface of the hollow rod 61, and the aperture of the circular hole 601 is small, which can limit the flow rate of air. The inner wall of the hollow rod 61 is elastically connected to the sliding rod 63 through the connecting spring 64, and the lower surface of the sliding rod 63 is provided with a universal wheel 62. When the sliding rod 63 moves, it will drive the universal wheel 62 to move synchronously.

When the sliding rod 63 moves upward, it will squeeze the connecting spring 64 to generate a reaction force. The upper surface of the sliding rod 63 is made of rubber. The piston of the sliding rod 63 is connected to the inner wall of the hollow rod 61. When the sliding rod 63 moves upward, it will also squeeze the air inside the hollow rod 61 to be discharged from the circular hole 601. The upper surface of the hollow rod 61 is fixedly connected to the lower surface of the bottom plate 1.

[0039] Working principle: When the device is used, firstly, the concrete slabs to be stacked are placed on the support plate 35, and then the electric push rod 55 is started to shorten the electric push rod 55. When the electric push rod 55 is shortened, the connecting block 56 will move closer to the fixing ring 52, and the connecting plate 54 will be squeezed and rotated. The rotating connecting plate 54 will drive the rotating plate 53 to rotate, and the rotating rotating plate 53 will drive the connecting plate 54 on the other side to rotate and the connecting block 56 on the other side to move. When the connecting block 56 moves closer to the fixing ring 52, the fixing plate 57, the compression spring 58 and the clamping plate 59 will move toward the center of the support plate 35 to clamp and fix the concrete slab. When clamping, the clamping plate 59 will first contact the concrete slab. When the clamping force is too large, the compression spring 58 will shrink, which can prevent the clamping force from being too large and the concrete slab from being broken due to its own rigidity.

[0040] After the fixation is completed, push the push handle 2 to move the device to the position where it needs to be stacked. During the movement of the device, road bumps will cause the slide bar 63 to slide upward to squeeze the connecting spring 64 to generate a reaction force, and will squeeze the air inside the hollow rod 61 to be discharged from the circular hole 601. Since the aperture of the circular hole 601 is small, the air flow rate can be limited, so the speed of pressure transmission can be slowed down, thereby alleviating the frequency of the device shaking due to bumps and enhancing the stability of the device. After the device is stable, the reaction force of the connecting spring 64 will push the slide bar 63 to move downward to the initial position. During the resetting process of the slide bar 63, the external air will be sucked into the hollow rod 61 from the circular hole 601 to maintain stable air pressure.

[0041] When reaching the designated position, the movement is stopped, and the motor 32 is started to drive the threaded rod 33 to rotate. The rotating threaded rod 33 will drive the slider 34, the support plate 35 and the concrete plate to move upward. When moving to a suitable height, the motor 32 is turned off and the electric push rod 55 is started to extend the electric push rod 55. When the electric push rod 55 is extended, it will drive the rotating plate 53 and the connecting plate 54 to rotate in the opposite direction. The connecting plate 54 rotating in the opposite direction will drive the connecting blocks 56, the fixing plate 57, the compression spring 58 and the clamping plate 59 on both sides to rotate and open, thereby releasing the clamping of the concrete plate. Then the hydraulic push rod 37 is started to push the concrete plate on the support plate 35 down to complete the stacking work.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
