Abstract

The invention relates to a bottom hole three-jaw centering mobile platform applied to a special environment, and belongs to the field of special environment cleaning. The bottom hole three-jaw centering mobile platform is characterized in that a lifting support assembly is fixedly connected on a vehicle body, a centering structure is fixedly connected on the lifting support assembly, the vehicle body is structurally characterized in that four Mecanum wheels with servo motors are connected to a vehicle body portion, the bottom surfaces of two motor supports are fixed on the vehicle body portion, the vertical surfaces of the motor supports are used for fixing the motors, output shafts of the motors are connected with lead screws through couplers, a bearing is arranged at each of the two endsof each lead screw and used for fixing and limiting, two mirror-image guide plates are arranged on the vehicle body portion, the bottom surfaces of the guide plates are connected with the vehicle body portion, and the inner sides of the vertical surfaces make contact with a guide cylinder of the lifting support assembly. The bottom hole three-jaw centering mobile platform has the advantages thatthe structure is novel, abrasion to the using environment is reduced, a better centering effect is achieved, and the functions of accurate grinding cleaning, positioning observation and the like can be achieved.

Description

technical field [0001] The invention belongs to the field of special environment cleaning, and in particular relates to a three-claw centering mobile platform for holes on the bottom surface used in special environments. Background technique [0002] For special environments that are difficult for many workers to reach, such as the area where thermocouples are installed in nuclear power plant spent fuel pools, it is often necessary to carry out accurate alignment inspections on a regular basis. In this working environment, the damage to the working environment by each component should be minimized as much as possible, and at the same time, it must be ensured Relatively high centering accuracy, so that it is convenient for the staff to detect and clean. The current common concentric centering mechanism usually damages the centering parts greatly, and is not suitable for many special environments that need to reduce debris generated by wear as much as possible. At the same time...
