Obstacle-crossing carbon-free trolley running in S-shaped mode

Abstract

The invention relates to an obstacle-crossing carbon-free trolley running in an S-shaped mode. A wire wheel support 3 and a secondary fixed pulley 1 are mounted on a potential energy support 4 through a wire wheel shaft 14. A front wheel 7 is mounted on a front wheel support 6 through a front wheel steering shaft. A driving wheel 20, a driven wheel 11 and a pinion 12 are mounted on a driving shaft 16. A bull gear 13 and a small belt pulley 17 are mounted on a bobbin 14. A large belt pulley 18 is mounted on a shaft connected to a crank connecting rod 9. The pinion 12 is engaged with the bull gear 13. The small belt pulley 17 is connected to the larger belt pulley 18 through a belt 19. One end of a rope 22 is connected to a potential energy block 2, the rope 22 bypasses the secondary fixed pulley 1 and is wound in a wire winding groove 15, and the other end of the rope 22 is positioned through a wire hole in the secondary fixed pulley 1. According to the invention, the potential energy generated by the falling of the potential energy block is converted into the kinetic energy of the trolley, the trolley can periodically avoid obstacles from a long distance based on a preset track and through gear engaging and belt transmission, and the trolley is simple in structure and convenient to use.

Description

technical field [0001] The invention relates to a carbon-free trolley, in particular to an obstacle-free carbon-free trolley that travels in a "∽" shape. Background technique [0002] Such as figure 1 As shown, it is required to give a gravitational potential energy, according to the principle of energy conversion, design a mechanical device that can convert the gravitational potential energy (drop height 400mm) into mechanical energy and can be used to drive the trolley to walk and turn. The carbon-free car adopts a stable structure with three wheels, which can automatically avoid obstacles on the road ahead when moving forward. (The distance between two obstacle stakes is 700-1300mm, and the specific distance is determined by lottery at the competition site). The biggest advantage of the carbon-free car is that it uses gravitational potential energy as the only energy, realizing carbon-free in the true sense.

Problems solved by technology

[0003] The driving mechanism of some trolleys is to wind the traction rope directly on the drive shaft, so its starting torque is small, which is not conducive to the start of the trolley, and the distance traveled by the trolley is controlled; some trolley wheels use fixed pulleys, so that heavy objects The fall is relatively fast, and the trolley is easy to overturn when turning; some trolleys are not very accurate in adjustment and cannot meet the requirements of cycle and amplitude; some mechanisms are relatively heavy, which not only increases the mass of the trolley itself, but also increases energy during the movement process. attrition, making it impossible to complete the race
