Detailed Description

To make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the embodiments of the present invention are combined to clearly and completely describe the technical solution in the embodiments of the present invention, and obviously, the described embodiments are some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

In this embodiment, each driving part of the air bag plugging robot includes a servo motor 51 and a speed reducer 52, and water may exist in the pipeline along with the entry of the robot into the pipeline, so that the waterproof design of the driving part is very important. In this embodiment, each driving member is fixed in the waterproof housing, as shown in fig. 1 and 2, the specific structure is as follows:

comprises a sealing shell 53, a sealing cover 54, a waterproof joint 55 and an inflation joint 56; one end of the sealing shell 53 is open and is fixed with the sealing cover 54 in a sealing way, the other end is provided with a through hole for the output end of the speed reducer 52 to penetrate out, and the sealing shell 53 is provided with a waterproof joint 55 and an inflation joint 56.

The sealing housing 53 is formed by welding a stainless steel plate and a sealing flange, and a sealing groove is formed on the flange surface for mounting an O-ring 57. The sealed housing 53 closely fits the exterior of the reduction motor and has a step, and the waterproof connector 55 and the air charging connector 56 are provided on the vertical face of the step, so that the overall size is compact. The sealing cover 54 is a stainless steel finish-machined part, and ensures that the O-shaped sealing ring 57 is uniformly pressed in the sealing groove in the process of pressing the O-shaped sealing ring 57. The O-shaped sealing ring is mainly used for waterproof sealing, and water leakage at the end face is avoided. The waterproof joints 55 are provided with a plurality of outlets for cables and network cables to ensure that the outlet does not leak water, and the inflation joint 56 is mainly used for inflating the sealing shell 53 to ensure that the inside of the shell has certain air pressure to ensure the sealing performance of the shell.

The motor 51 and the speed reducer 52 are fixed together by screws, an O-shaped sealing ring is sleeved at the front end seam allowance position of the combined speed reducer motor, the speed reducer motor is fixed on the motor sealing shell 53 by screws, a silica gel gasket and a pressure pad, the O-shaped sealing ring is sleeved in a sealing flange groove at the rear end of the motor sealing shell 53, and the sealing cover 54 is fixed on the motor sealing shell 53 by screws, the silica gel gasket and the pressure pad. The waterproof connector 55 is attached to the motor sealing case 53 by a nut. The air charging connector 56 is attached to the motor seal housing 53 by a nut.
