Self-gravity reciprocating conveying mechanism

The utility model discloses a self-gravity reciprocating conveying mechanism which is used for conveying workpieces and comprises an inclined beam body, a counterweight sliding assembly, a hanging sliding assembly and a steel wire rope. The upper surface of the inclined beam body is provided with an upper rail arranged in the axial direction of the inclined beam body, the lower surface of the inclined beam body is provided with a lower rail arranged in the axial direction of the inclined beam body, the lower portion of the balance weight sliding assembly is located on the upper rail, the upper portion of the hanging sliding assembly is located on the lower rail, and the steel wire rope is connected with the balance weight sliding assembly and the hanging sliding assembly. The hanging sliding assembly is used for driving the balance weight sliding assembly to slide in a reciprocating mode so that the hanging sliding assembly can reach the lower end from the upper end of the inclined beam body. The counterweigh
