Abstract

The invention provides a high-safety-performance large goods elevator. The high-safety-performance large goods elevator comprises a lifting device and two safety gears, wherein each safety gear comprises a shell, a clamping block, a second spring, a moving seat and a connecting block, the shells are fixed relative to an elevator car, the clamping blocks are arranged in the shells, one ends of theclamping blocks are used for clamping a guide rail in an elevator shaft, the other ends of the clamping blocks act on the moving seats, the ends, acting on the moving seats, of the clamping blocks areof trapezoidal structures, second springs are connected between the clamping blocks and the inner walls of the shells and used for keeping the clamping blocks away from the guide rail in the elevatorshaft, and connecting blocks are installed in the movable seats, the lifting device comprises a first brake rod and a second brake rod, the first brake rod is hinged to the connecting block of one safety gear, and the second brake rod is hinged to the connecting block of the other safety gear. The high-safety-performance large goods elevator solves the problem that in the prior art, safety gearscannot be driven by the end of the first brake rod and the end of the second brake rod.
