Powered double-rod type telescopic device for inspection robot

Abstract

The invention discloses a powered double-rod type telescopic device for an inspection robot. The powered double-rod type telescopic device comprises a mounting rack, a rotating shaft, a roller, two telescopic rods, belts, a mounting platform and a driving device, wherein the rotating shaft is arranged on the mounting rack; the mounting platform is fixed at the lower end of the telescopic rods; thedriving device is used for driving the roller; the roller and a power supply are arranged at the upper end of the mounting rack; the two telescopic rods are fixed at the lower end of the mounting rack in parallel; the axial direction of the rotating shaft is parallel to the axial direction of the roller; one ends of the belts are connected with the roller, and the other ends of the belts pass through the rotating shaft and then stretch into the telescopic rods; the belts are located in the centers of the telescopic rods and connected with a telescopic rod bottom plate; the two telescopic rodsare respectively connected with the roller by virtue of a belt; the driving device drives the roller to rotate, the roller drives the belts, the rotating shaft transforms rotation of the belts alongthe roller into vertical up-and-down motion, and the belts further drive the telescopic rods to stretch up and down so as to drive the mounting platform to move up and down. According to the device disclosed by the invention, the synchronism of the two telescopic rods during movement is ensured, and an encoder is increased to accurately control the telescopic height.

Description

technical field [0001] The invention belongs to the field of electric power technology, and in particular relates to a power double-rod expansion device for an inspection robot. Background technique [0002] As a telescopic rod mechanism for vertical up and down movement, it is widely used in various occasions such as detection, shooting, and transportation. At present, the commonly used telescopic rods mostly adopt a single-rod or double-rod structure. When a single-rod telescopic rod is used to hang heavy objects, the movement in the horizontal direction will cause the telescopic rod to swing back and forth seriously, which is not conducive to hanging and transportation; The two-rod telescopic rod will have different lengths when the telescopic rods move due to the asynchrony of the two movements. When asynchrony occurs, the load moment of the power device of the telescopic rod will increase and the situation will be stuck; At the same time, the double telescopic rods do ...
