The invention provides a small-radius turning climbing overhead rail type robot driven by an external chain. Comprising a profile steel guide rail, a chain with a shifting block, a supporting chain wheel module, a first driving module, a U-shaped base, a second driving module, a pre-pressing mechanism and a steering auxiliary mechanism. Two different driving modes of the friction wheel and the external driving chain can be utilized, so that the track inspection device can smoothly turn and go uphill and downhill. When the vehicle runs on a flat road, only the rubber-coated power friction wheel motor reducer works, and the pre-pressing mechanism enables the driving mechanism to be firmly fixed on the guide rail under the action of the torsion spring, so that the driving mechanism cannot deviate or incline. When encountering an up-and-down ramp, the climbing damping spring can adjust the longitudinal displacement change of the friction wheel to avoid jamming. During turning, the auxiliary wheel carrier can deflect along with the guide rail, the steering auxiliary wheel of the steering auxiliary mechanism can keep abutting against the web plate of the profile guide rail under the action of the turning damping spring, and the dislocation phenomenon is prevented.
本发明提供了一种小半径转弯的外置链条驱动爬坡吊轨式机器人。包括型钢导轨,带有拨块的链条,支撑链轮模组,第一驱动模组,U型底座,第二驱动模组,预压机构,转向辅助机构。本发明可以利用摩擦轮与外置驱动链条的两种不同的驱动方式,实现轨道巡检装置顺利过弯、上下坡。在平道行驶时,只有包胶动力摩擦轮电机减速机工作,在扭簧的作用下预压机构使驱动机构能够牢牢固定在导轨上,不会使驱动机构发生偏移或倾斜。当遇到上下坡道时,爬坡阻尼弹簧可以调节摩擦轮的纵向位移变化,避免卡死。转弯时,辅助轮架会随导轨偏摆,转向辅助机构的转向辅助轮在转弯阻尼弹簧的作用下,能保证与型材导轨的腹板保持抵接,防止出现错位的现象。
