Rotary type quick clamping device of pipeline grinding robot

Abstract

The invention discloses a rotary type quick clamping device of a pipeline grinding robot. The rotary type quick clamping device is special for quickly clamping a non-detachable pipeline on a construction site for the pipeline grinding robot or other grinding equipment. The rotary type quick clamping device comprises a machine frame part, a rotary feeding part, a braking mechanism, a coaxial rotating joint and a plugging and unplugging mechanism. By means of the coaxial rotary joint and the plugging and unplugging mechanism, the whole device can be opened or closed and is placed on the non-detachable pipeline on the construction site. One sections of T-shaped feeding rods are restrained by linear sliders on the machine frame part, and the other sections of the T-shaped feeding rods penetrate through arc through grooves in the rotary feeding part and are tangential to and restrained by the arc through grooves. The rotary feeding part is rotated under the action of external force, the plurality of feeding rods in a group are pushed by the plurality of arc through grooves with consistent appearance to be fed synchronously at the same speed towards the to-be-ground pipeline at the sametime to clamp the pipeline, it is ensured that the axis of the pipeline grinding robot coincides with the axis of the pipeline and meanwhile the feeding rods are uniform in stress and high in safety,and a reliable basis is laid for the subsequent grinding work of the pipeline grinding robot. The braking mechanism performs keeping.

Description

Technical field [0001] The invention relates to a rotary quick clamping device of a pipe polishing robot [0002] technical background [0003] According to the "Regulations on Safety and Supervision of Pressure Pipelines", industrial pressure pipelines must be inspected regularly. There are a large number of pressure pipelines in petrochemical, thermal power plants, boilers and other places. There are more than 270 thermal power plants under the five major power generation companies, and each thermal power plant has a large number of pipelines to be cleaned and polished every year. At present, manual polishing of pipelines accounts for the vast majority of the market, but the polishing work environment is difficult and harsh. Workers must stand on high scaffolds and continue to polish their work. Fatigue, noise, vibration, and dust can cause physical injury to workers, and when grinding pressure pipes, accidents can easily cause casualties. The use of more mature polishing and...

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.
