Description

Carbon-free trolley

Technical field

The present invention relates to a kind of carbon-free trolleys, belong to field of mechanical technique.

Background technique

A kind of contest class carbon-free trolley, it is desirable that: design is driven voluntarily small with direction controlling function with gravitional force Vehicle, it is desirable that thus energy needed for trolley completes everything in the process of walking gives gravitional force conversion and obtains, can not To use the energy in any other source.It is required that trolley has course changing control mechanism, and this course changing control mechanism is with adjustable Function, to adapt to be placed with the competition venue of different spacing barriers.It is required that trolley is tricycle structure.This gives gravitional force The standard test weight of 1Kg obtains, it is desirable that counterweight can falling head be 400 ± 2mm.Racing track width be 2 meters, set out end line away from First spacing between obstacle and obstacle and obstacle is all the same.Contest trolley can automatically bypass on racing track when forward to be arranged Barrier, barrier is the pole of diameter 20mm, high 200mm, is put along racing track middle line is equidistant.Trolley effectively around Barrier method are as follows: after trolley crosses an obstacle from racing track side, integrally cross racing track middle line and barrier is not knocked down or released Barrier setting circle；Continuous operation, until trolley stops.The effective range ability of trolley are as follows: when stopping trolley distalmost end with Vertical range between outbound track.Current existing contest class carbon-free trolley has many less perfect places.First, trolley Driving device is directly wound in traction rope on wheel drive shaft, causes the staring torque of trolley smaller, is unfavorable for rising for trolley Step, while the operating range of trolley being made to be affected.Second, when debugging trolley, by winding position and traction rope length It influences, nose wheel angle can not accurately be adjusted, cause debugging inconvenient, influence the obstacle detouring traveling of trolley.Third, in trolley body not With variable pitch device, the competition venue of different spacing obstacles is not adapted to.Fourth, trolley components are excessively complicated, processing cost It is higher, less meet the requirement that trolley is carbon-free, inexpensive.
