Abstract
The utility model discloses a high-strength single-stage current collector in the field of mobile power supply equipment. The high-strength single-stage current collector comprises a current collector clamp and a current collector brush which are connected by a supporting arm. The supporting arm comprises upper connecting rods in parallel and lower connecting rods in parallel. The upper connecting rods and the lower connecting rods are connected by a tension spring and a position-limiting plate which are arranged in a staggered manner. One ends of the upper connecting rods are hinged to one end of a first supporting shaft while one ends of the lower connecting rods are hinged to the other end of the first supporting shaft. The first supporting shaft is mounted on the current collector clamp. The other ends of the upper connecting rods are hinged to one end of a second supporting shaft, while the other ends of the lower connecting rods are hinged to the middle of the second supporting shaft. The other end of the second supporting shaft is connected with the current collector brush. The supporting arm with parallelogram structure achieves simple structure, low production cost, and highly stable and reliable structure. The high-strength single-stage current collector can be used for supplying power to hoisting equipment.
