Pipe grinding robot rotary fast card device

Abstract

The invention discloses a rotary fast clamping device for a pipeline grinding robot, which is specially used for fast clamping of a non-detachable pipeline of a pipeline grinding robot or other grinding equipment at a construction site. The device is composed of a frame part, a rotary feed part, a brake mechanism, a coaxial rotary joint, and a plug-in mechanism; the coaxial rotary joint and the plug-in mechanism can open and close the entire device, and the device cannot be placed on the construction site. on the disassembled pipe. T-shaped feed rod, one part is constrained by the linear slider on the frame part, and the other part passes through the arc-through slot on the rotary feed member and is tangentially constrained, and rotates the rotary feed part under the action of external force, several shapes Consistent arc through grooves push several feed rod groups towards the pipe to be polished at the same speed at the same time to achieve clamping, ensuring that the axis of the pipe grinding robot coincides with the axis of the pipe and the force on the feed rod is uniform and safe. The sanding robot's sanding work lays a solid foundation. The braking mechanism is maintained.

Description

technical field [0001] The invention relates to a rotary fast card device for a pipe grinding robot [0002] technical background [0003] According to the "Pressure Pipeline Safety and Supervision Regulations", industrial pressure pipelines must be inspected regularly. There are a large number of pressure pipes in petrochemical, thermal power plants, boilers and other places. There are more than 270 thermal power plants affiliated to the five major power generation companies alone, and each thermal power plant has a large number of pipelines that need to be cleaned and polished every year. At present, the vast majority of pipes are manually polished on the market, but the working environment for polishing is harsh and harsh. Workers have to stand on high scaffolding and continue to polish the work. Fatigue, noise, vibration and dust will all cause harm to the workers, and when grinding the pressure pipeline, once an accident occurs, it is very easy to cause casualties. T...

Problems solved by technology

As the first step in the grinding work of the external pipe grinding robot, the importance of the installation of the robot is particularly prominent. If the axis of the grinding area of ​​the grinding robot does not coincide with the axis of the pipe, the grinding will be uneven, affecting the grinding accuracy and poor safety.
