Problems solved by technology

[0003] The present invention aims to solve the problem that the expansion joint structure is adopted between the piping pipe and the header of the existing naval boiler. Due to the narrow space in the header and the harsh working conditions, it is very inconvenient to manually expand the joint operation, and further proposes a small space Automatic Tube Expansion Robot

Abstract

The invention relates to an automatic tube expansion robot, in particular to a small-space automatic tube expansion robot. The problems that an expanded connection structure is adopted between pipelines and headers of existing ship boilers, and due to the fact that space in the headers is narrow and work conditions are severe, manual expanded connection operation is quite inconvenient are solved. The small-space automatic tube expansion robot comprises a robot body, a walking driving shaft, a walking driven shaft, a walking hydraulic motor, a gearbox, a tube expander connecting mechanism, two walking driving wheels, two walking driven wheels and three fixed supporting air cylinders. The walking driving shaft and the walking driven shaft are sequentially arranged on the robot body from front to back side by side in parallel, the axis of the walking driving shaft and the axis of the walking driven shaft are perpendicular to the center line, in the length direction, of the robot body, the two ends of the walking driving shaft are each provided with one corresponding walking driving wheel, and the two ends of the walking driven shaft are each provided with one corresponding walking driven wheel. The small-space automatic tube expansion robot is used for tube expansion.

Description

technical field [0001] The invention relates to an automatic tube expanding robot, in particular to an automatic tube expanding robot in a small space, which belongs to the field of boilers. Background technique [0002] Ship boilers with a displacement of more than 10,000 tons are compact in structure and small in space. The boiler tube and header adopt an expansion joint structure, and the inner space of the header can only allow one person to drill in. The working conditions were very poor. Existing expansion joint machines in small spaces and headers use external power heads to transmit power to the transmission box inside the equipment through the transmission rod, and people hold the transmission box with their hands for expansion. Due to the narrow space inside the equipment, the working environment for people inside the equipment is very harsh. The transmission box weighs 7 kilograms, and each person can only insist on expanding and connecting about 5 pipes. If th...
