Description
Technical Field
[0001] The utility model belongs to the technical field of curb stones, and particularly relates to a discharging and stacking device for processing concrete curb stones. Background Art
[0002] A curb stone is a marking stone set between a road surface and other structures. Curb stones are generally required to be set between the median strip and the road surface of urban roads, and between the sidewalk and the road surface. Curb stones are often required to be set at the edge of the central median strip of highways, the right edge of the driving lane or the outer edge of the road shoulder. Curb stones can be prepared from natural stones or concrete. After the concrete curb stones are cast and formed, they need to be polished (usually two surfaces and bevel angles). After processing, they need to be discharged from the corresponding polishing equipment and stacked.
[0003] For example, the patent with the application number CN202011151936.6 discloses a clamping and stacking tool for concrete blocks, including a concrete block clamp, a lifting device, and a gantry. The concrete block clamp includes a rectangular frame for installing various components. Double swing arms are hinged on both sides of the bottom of the rectangular frame. A first connecting rod is arranged on the upper part of the double swing arms. The lower ends of the double swing arms are hinged with clamping plates. A V-shaped frame is fixedly connected to the middle of the rectangular frame. A second connecting rod is arranged in the middle of the V-shaped frame. A hydraulic rod device is hinged between the first connecting rod and the second connecting rod. A first connecting plate is fixedly connected to the middle of the bottom of the rectangular frame. A control box is arranged above the first connecting plate. A control device and a sensor group are arranged in the control box. Through holes adapted to the sensor group are opened in the first connecting plate. A rotating box is fixedly connected to the top of the control box. A rotating cylinder is rotatably connected to the top of the rotating box. A second connecting plate is fixedly connected above the rotating cylinder. The second connecting plate is fixedly connected to the lifting device. The hydraulic rod device, the sensor group and the control device are electrically connected.
