Embodiment

[0024] 1. First, introduce the mechanical device of the present invention: the present invention relates to a pinch wheel device for an overhead high-voltage transmission line patrol robot, including a pinch wheel part and a pinch wheel transmission part; Wheel support 17 is connected as a whole. The pinch wheel components include pinch wheel seat 3, pinch wheel 1, pinch wheel shaft 12, rolling bearing 13, pinch wheel seat cap 2, baffle 6, baffle joint 5, Hall sensor 8, magnetic steel 4. The pinch wheel seat 3 supports the pinch wheel shaft 12 and the pinch wheel 1 nested thereon through rolling bearings, and the two ends of the pinch wheel shaft 12 are axially positioned by the pinch wheel seat cap 2 . The pinch wheel 1 can rotate around its own axis, and four magnetic steels 4 are evenly distributed on the circumference of the pinch wheel 1 , correspondingly, Hall sensors 8 are installed at the corresponding positions of the pinch wheel seat 3 . One end of the baffle 6 is ...

Abstract

The invention provides a press wheel device for an inspection robot of an overhead high-voltage power transmission line. The press wheel device comprises a press wheel part and a press wheel transmission part, wherein the two parts are connected into a whole by a press wheel support, the press wheel part can rotate around the axial line of the press wheel support so as to be adaptive to the power transmission lines at different dip angles, two Hall sensors are arranged on the press wheel part, one of the two Hall sensors is used with magnetic steel on a press wheel in a matching way, is used for detecting whether a travelling wheel slips or not and also can be used for measuring the travelling distance of the robot, and the other Hall sensor is used with magnetic steel on a baffle plate in a matching way and used for detecting an obstacle on the power transmission line in a touch way. In the press wheel transmission part, a press mechanism spring is used for increasing a press force of the press wheel on the power transmission line, so that the travelling wheel is effectively prevented from slipping; the whole press wheel device is driven by a single independent motor, a screw nut is used for transmission, and thus, the press wheel device is simple and reliable in structure, high in efficiency and high in practicability.

Description

technical field [0001] The invention relates to a pinch wheel device, in particular to a pinch wheel device for an overhead high-voltage transmission line patrol robot. Background technique [0002] The overhead high-voltage transmission line inspection robot is a mobile robot that inspects overhead high-voltage transmission lines. The inspection robot contacts the line through the walking wheel, and when the walking wheel rotates, the friction between it and the line is used to drive the robot to move. However, due to the influence of different lines, different sections of the same transmission line, different inspection environments, and different surface conditions of the line, the walking wheel often slips during the line inspection process, which greatly reduces the inspection efficiency of the inspection robot. , waste the energy of the inspection robot, and accelerate the loss of parts of the inspection robot. Traditionally, manual control is used to solve the slipp...
