Gear shifting and displacement carbon-free trolley walking in S-shaped path mode

Abstract

The invention discloses a gear shifting and displacement carbon-free trolley walking in an S-shaped path mode. The trolley comprises a trolley frame, a drive mechanism, a transmission mechanism, a steering mechanism and a gear shifting and displacement mechanism, wherein the drive mechanism, the transmission mechanism, the steering mechanism and the gear shifting and displacement mechanism are arranged on the trolley frame. Different from the prior art, the drive mechanism is connected with the transmission mechanism through a flexible cotton rope, the transmission mechanism is fixed to the trolley frame through a bearing block and connected with the steering mechanism through a drum shaft, front wheels of the trolley are supported unilaterally, and an angle fine-adjustment mechanism is in rigid connection with the steering mechanism. The gear shifting and displacement carbon-free trolley walking in the S-shaped path mode can walk in the S-shaped path mode when the distance between two barriers is within 700-1300 mm, and adjustable large-displacement walking can be achieved. The front wheels of the trolley are unique in design and good in removability; the front wheels are provided with axial positioning units, so that the running tracks of the trolley are uniform, symmetrical and high in precision.

Description

Technical field [0001] The invention relates to a carbon-free trolley, in particular to a gear-shifting and variable-pitch carbon-free trolley running on an S-shaped path. Background technique [0002] The current carbon-free cars are all designed and manufactured based on the propositions of the National College Student Engineering Training Comprehensive Ability Competition. The proposition requirements of the fourth competition: design a three-wheeled trolley, and the energy to drive it to walk and turn is obtained by the conversion of the given gravitational potential energy according to the principle of energy conversion. The energy required for the trolley to complete all actions in the walking process is converted from the given gravitational potential energy, and no other sources of energy can be used. The trolley is required to have a steering control mechanism, and the steering control mechanism has an adjustable function to adapt to the competition field with obstacles...

Problems solved by technology

If you only rely on the rocker fine-tuning mechanism for adjustment, the adjustable distance is small

Moreover, the front wheel of this utility model trolley has poor detachability. After the front wheel is unloaded in the competition, the front wheel processed on site is replaced for a new race. The front wheel has no axial positioning, and the bearing is easy to loosen and yaw. The problem makes the running track of the trolley change, and the running accuracy is greatly reduced
