Description

High-temperature-resistant shaft insulation structure

Technical field

The invention belongs to the technical field of robots, and particularly relates to a high-temperature-resistant shaft insulation structure for fire-fighting robots and special robots.

Background technique

Fire-fighting robots, as a type of special robots, play an increasingly important role in fire fighting and rescue. Various large-scale petrochemical enterprises, tunnels, subways, etc. are constantly increasing, and oil and gas, poisonous gas leaks and explosions, tunnels, subways and other disasters are increasing. Fire-fighting robots can replace fire-fighting rescue personnel to enter the scene of dangerous accidents such as flammable and explosive, toxic, anoxic, and dense smoke for data collection, processing, and feedback.

Fire-fighting robots need to work in high-temperature environments, and the shafting needs to be able to work normally in high-temperature conditions to ensure the normal movement function of the robot in high-temperature environments. The large load ensures that the robot can move normally in the fire. In the prior art, the shafting structure is used in a case where the ambient temperature is low, and when the ambient temperature is high, it is easy to damage and fail, thereby affecting the motion function of the robot.

Summary of the Invention

In order to solve the shortcomings of the prior art, an object of the present invention is to provide a heat-resistant shafting heat-insulating structure. The thermal layer is thermally insulated, so that the shafting structure can still work normally in a high temperature environment above 1000 ° C.

In order to achieve the above object, the present invention provides a high-temperature-resistant shaft insulation structure including a bearing assembly, a high-temperature shaft, a heat-insulating layer, a low-temperature shaft, and a motor reducer.

One end of the low temperature shaft is connected to the motor reducer, and the other end thereof is connected to one end of the high temperature shaft through the heat insulation layer;

The other end of the high temperature shaft is connected to the bearing assembly.

Further, the thermal insulation layer is an axial thermal insulation layer, and the material thereof is an aerogel felt.

Further, the high-temperature shaft is connected to the shaft of the bearing assembly through a D-shaped hole. Further, the low-temperature shaft is connected to an output shaft of the motor reducer through a D-shaped hole.

Furthermore, the high temperature shaft and the low temperature shaft are hollow shafts.

The high-temperature-resistant shaft insulation structure provided by the present invention divides the shaft into a high-temperature shaft and a low-temperature shaft, and an axial heat insulation layer is provided between the high-temperature shaft and the low-temperature shaft, thereby reducing the heat transmitted to each component on the shaft, thereby The components of the shafting system can keep working normally even when the external temperature is high. The technical effect is that when the robot works in a high temperature environment, its motion function can be used normally.

Other features and advantages of the present invention will be explained in the following description, and partly become apparent from the description, or be understood by implementing the present invention.
