Carbon-free trolley adaptable to S-shaped path with rods spaced from one another by different distances

Abstract

The invention relates to a carbon-free trolley adaptable to an S-shaped path with rods spaced from one another by different distances. According to the carbon-free trolley adaptable to the S-shaped path with the rods spaced from one another by different distances, an adjustment gear is adopted by a pitch control mechanism to be matched with a driving gear and a driven gear, a main gear with an eccentric ejecting column is adopted by a steering mechanism, a front ejecting rod is made to drive a front axle to swing through the linkage of the eccentric ejecting column and a push rod, and springs are used for making the front ejecting rod be kept in good contact with the front axle and a rear ejecting rod be kept in good contact with the eccentric ejecting column. The carbon-free trolley adaptable to the S-shaped path with the rods spaced from one another by different distances is reasonable in design, simple in structure, convenient to disassemble and assemble, convenient to debug, stable in operation, stable in traveling and reliable in steering, the energy utilization rate is high, it is guaranteed that a competition can be completed smoothly and a good result is obtained, and the trolley is also suitable for automatic barrier-avoidance traveling under the condition that no energy supply is available so as to fulfill a specific task.

Description

technical field [0001] The invention relates to a carbon-free trolley, in particular to a carbon-free trolley which can adapt to S-shaped paths with different pole distances. Background technique [0002] The carbon-free trolley is a three-wheeled trolley that uses the potential energy of gravity as the only energy and has the function of continuous obstacle avoidance. Its principle is to lift the weight to a specified height, and the weight will fall by itself under the action of gravity. The flexible rope tied to the weight changes the direction of the pulling force through the pulley installed on the pulley seat, and the other end of the rope is wound on the drive. On the mechanism, the motion is transmitted to the rear wheel shaft through the transmission mechanism, and the rear wheel is driven to rotate, thereby completing the forward movement of the trolley; the steering mechanism is used to make the front wheel turn left or right according to the sinusoidal cycle, so ...

AI Technical Summary

Problems solved by technology

[0004] In order to adapt to the different single-cycle lengths of the S-shaped path, that is, the pole distance, the above-mentioned S-shaped path-shifting carbon-free trolley needs to shift gears when changing the transmission ratio, so a shifting device must be provided; To realize the stable steering of the trolley due to the different rotational speeds of the side wheels, it is necessary to use a differential, so the structure of the above-mentioned prior art is relatively complicated.
