Self-control obstacle-crossing trolley driven by gravity potential energy

Abstract

The invention discloses a self-control obstacle-crossing trolley driven by gravity potential energy and belongs to the technical field of trolleys. The self-control obstacle-crossing trolley driven bythe gravity potential energy mainly solves the problem that single winding wheels of existing carbon-free trolleys cannot provide different speeds for the trolleys. The self-control obstacle-crossingtrolley is mainly characterized by comprising a trolley frame, a prime movement mechanism, a transmission mechanism, a driving mechanism, an electric control mechanism and a braking mechanism. The prime movement mechanism includes a weight, a rope, a fixed pulley, a fixed pulley shaft and supporting rods; the transmission mechanism includes a winding wheel, a winding wheel shaft, a large gear anda small gear, the winding wheel is integrally formed by three wheels different in radius, the weight is fixedly connected to one end of the rope, and the other end of the rope passes by the fixed pulley to be wrapped around the winding wheel; the driving mechanism includes a driving wheel shaft and driving wheels. According to the self-control obstacle-crossing trolley driven by the gravity potential energy, a driving force is changed by changing different positions of the rope on the winding wheel, so that various functions that the trolley moves smoothly on the flat ground, accelerates whengoing uphill and decelerates when going downhill are achieved.

Description

technical field [0001] The invention relates to the field of trolley technology, in particular to a self-controlled obstacle-crossing trolley driven by gravity potential energy. Background technique [0002] In the existing carbon-free trolleys, the traction wire is usually wound directly on the wheel axle on the prime mover, resulting in a small driving torque, and the trolley is not easy to start. The steering mechanism often uses a cam to control the steering of the trolley, which leads to high processing costs and increases Fine-tuning is difficult and difficult to control; at present, self-controlled obstacle-crossing vehicles driven by gravity potential energy are mainly composed of a frame, a prime mover, a transmission mechanism, a drive mechanism, an electronic control mechanism, and a brake mechanism. The prime mover usually adopts a wire wheel structure , However, a single winding wheel cannot provide different speeds for the trolley, and cannot guarantee that the...
