Carbon-free trolley capable of walking in closed '8'-shaped track

Abstract

The invention relates to a carbon-free trolley capable of walking in a closed '8'-shaped track. The carbon-free trolley comprises a bottom plate, stand columns, a front wheel and rear wheels, whereinthe stand columns are vertically positioned on the bottom plate; the front wheel is connected to the middle position of the front end of the bottom plate in a swinging manner through an adjusting frame, and a steering mechanism for enabling the front wheel to steer by pushing the adjusting frame to swing is arranged at the position, corresponding to the adjusting frame, of the bottom plate; two rear wheels are arranged, and the two rear wheels are mounted at two sides of the rear end of the bottom plate through a rear axle; a driving device for driving the rear wheels to rotate through gravitational potential energy and driving the front wheel to steer through the steering mechanism so that the carbon-free trolley walks in the closed '8'-shaped track is arranged on the stand columns. The carbon-free trolley capable of walking in the closed '8'-shaped track has the beneficial effects that the structure is simple, the cost is low, and the processing and the assembly are easy; only a fewkinematic pairs are adopted, so that the resistance is small, the energy consumption is low, the carbon-free trolley can walk out many 8 shapes, meanwhile, the walking process is stable, the adjustingfunction is convenient, and many pile-passing tracks can be generated.

Description

technical field [0001] The invention relates to the field of carbon-free trolleys, in particular to a carbon-free trolley capable of walking in a closed "8" shape. Background technique [0002] The carbon-free trolley is a three-wheeled rear-drive trolley with continuous obstacle avoidance function that only uses gravitational potential energy as driving energy. Facing the reduction of coal resources, the concept of carbon-free has been paid more and more attention. The principle is to raise the weight to a specified height, and the weight will fall by itself under the action of gravity. The weight is connected to a flexible wire, and the direction of the pulling force is changed through a movable pulley. The other end of the flexible wire is connected to the drive shaft of the trolley to convert potential energy into mechanical energy , so as to drive the car forward to avoid obstacles and get out of the "8" pattern. Since the gravitational potential energy is the only en...
