Driving roller

Abstract

The invention discloses a driving roller. The driving roller comprises an outer cylinder and an inner cylinder arranged inside the outer cylinder, a motor is fixedly arranged inside the inner cylinder, the output shaft of the motor sleeves with a first rotating piece, and the outer peripheral surface of the first rotating piece is fixedly connected with the inner wall of the outer cylinder in a sealing mode; and the other end of the inner cylinder is provided with a second connecting piece, and the inner cylinder and the outer cylinder are rotationally connected together through the second connecting piece, wherein the second connecting piece is hermetically connected with the inner cylinder and the outer cylinder correspondingly. The driving roller has the beneficial effects that the motor is fixedly arranged inside the inner cylinder in a sealing mode, so that the waterproof performance is good; the inner cylinder and the outer cylinder are enabled to be connected rotationally through the first connecting piece and the second connecting piece, the outer cylinder is sleeved with the shell with spiral blades, when the roller of the robot is in contact with the inner wall or the sludge of the pipeline, friction is carried out by rotating of a spiral roller to the inner wall of the pipeline or the sludge to drive the pipeline robot to move forward, so that the contact area is large, and slipping is avoided; and when the roller of the robot is suspended in water, the spiral roller is equivalent to a propeller, the spiral roller rotates to be drained away water backwards and drives the pipeline robot to move forwards.

Description

technical field [0001] The invention relates to a driving drum. Background technique [0002] The environment of municipal pipelines is very harsh, and after long-term use, it is prone to corrosion, fatigue damage, or potential internal defects of the pipeline to develop into damage and cause leakage accidents, etc., especially for water pipelines, which are also prone to blockage and other accidents. Therefore, the in-pipe detection and desilting of pipelines is a very important practical project. At present, most of the in-pipe detection and decontamination are performed manually, which is limited by factors such as the size of the pipeline and the harsh environment, resulting in high work intensity and low work efficiency. The problem currently arises with pipeline bots. The robot needs enough friction to provide forward power to walk in the pipeline, and it works underwater, so waterproof is very important. Most of the existing pipeline robots are roller-type, and the d...
