Abstract

The invention relates to a diameter-variable support mechanism for a pipe section. The diameter-variable support mechanism comprises a main connection plate, a connection plate, a motor, a driving gear, n driven gears and n same diameter-variable mechanisms. The main connection plate and the connection plate are all round plates and are fixed on an external machine base in an eccentric and parallel mode. The n diameter-variable mechanisms are circumferentially and evenly distributed along the main connection plate and the connection plate and are radially installed among the inner wall of a support pipe section, the main connection plate and the connection plate. Inner ends of the n diameter-variable mechanisms are positioned and installed between the main connection plate and the connection plate and are connected with the motor through the n driven gears and the driving gear, and the outer ends of the n diameter-variable mechanisms support the inner wall of the pipe section through an auxiliary wheel in a rolling contact mode. The diameter-variable support mechanism can automatically adjust the center to adapt to the pipe section, is large in pipe section diameter adaption range, can achieve underactuation, and has good position and support functions.

Description

technical field [0001] The invention relates to a pipe section variable diameter support mechanism. Background technique [0002] The variable diameter support mechanism of the pipe section is a kind of change of the diameter of the support mechanism through stretching and bending. It generally includes a variable diameter drive unit, a variable diameter transmission unit, an actuator, and a supporting component. [0003] The pipe section variable diameter support mechanism is a pipe section support that can be applied to pipe diameter changes, especially in boiler plants and power plants. The inner wall of the pipe section with a large diameter needs to be welded, welded, repaired, painted, and inspected. It is required that the variable diameter support mechanism of the pipe section installed on the robot can play a role in positioning and supporting the pipe section and automatically adjusting the center. [0004] Looking at the existing data, people use many ways to ad...
