Piston type pneumatic motor for emergency rescue

Abstract

The invention relates to the technical field of pneumatic motors, in particular to a piston type pneumatic motor for emergency rescue. According to the technical scheme, the device comprises a fixing seat and a body, buffer columns are installed at the four corners of the top of the fixing seat, a supporting seat is installed on the outer surfaces of the buffer columns and located on the top of the fixing seat, the body is installed on the top of the supporting seat, and a driving shaft is installed in the middle of the interior of the body; buffering springs are installed on the outer surfaces of the buffering columns and located at the gap positions of the supporting seat and the base, and spring seats are installed on the tops of the buffering columns and located on the upper surface of the supporting seat. The problems that a driving shaft of an existing device continuously rotates under the inertia effect after air inlet is closed, the driving shaft cannot be stopped immediately, the rescue effect during rescue is affected, the use safety is poor, a piston type pneumatic motor is large in vibration force in the operation process, the piston type pneumatic motor cannot be buffered, and the use stability of the motor is poor are solved. And the stop speed of the driving shaft is increased, so that the use safety of the pneumatic motor is improved.

Description

technical field [0001] The invention relates to the technical field of air motors, in particular to a piston-type air motor for emergency rescue. Background technique [0002] Pneumatic motors, also known as wind motors, refer to devices that convert the pressure energy of compressed air into rotational mechanical energy. Generally used as a source of rotational power for more complex devices or machines. According to the structure, air motors are classified into: vane air motors, piston air motors, compact vane air motors, and compact piston air motors. Air motors are devices that convert the pressure energy of compressed air into rotational mechanical energy. Its function is equivalent to that of an electric motor or a hydraulic motor, that is, the output torque is used to rotate the drive mechanism. [0003] In the existing air motor, the drive shaft continues to rotate under the action of inertia after the air intake is closed, and it cannot be stopped immediately, whi...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a piston-type air motor for emergency rescue, which has the advantage of high stability in use, and solves the problem that the drive shaft of the existing device continues to rotate under the action of inertia after the air intake is closed, and cannot be stopped immediately, which affects the The rescue effect during rescue is poor in use safety, and the piston air motor has a large vibration force during operation, which cannot be buffered, poor stability of the motor, and poor service life.
