Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic motors, in particular to a safety braking device for pneumatic motors. Background Art

[0002] A pneumatic motor, also known as a wind motor, is a device that converts the pressure energy of compressed air into rotational mechanical energy. It is generally used as a rotational power source for more complex devices or machines. Pneumatic motors are classified according to their structure into: vane-type pneumatic motors, piston-type pneumatic motors, compact vane-type pneumatic motors, and compact piston-type pneumatic motors. The brake of a pneumatic motor is a braking system that uses air pressure. The principle is to use compressed air through a cylinder to act on the brake pads and prevent the motor from rotating. The air brake system consists of brake pads, cylinders, air valves, and pipes. When the system is connected to the air source, high-pressure air enters the cylinder, causing the piston to move to the right, pressing the brake pads and preventing the motor from continuing to rotate.

[0003] In the prior art, the output end of the motor is braked by pushing the brake pad into contact with the output end of the motor through gas, resulting in severe friction between the brake pad and the output end. The life of the brake pad and the output end is limited, the braking time is long, and the braking efficiency is low. Utility Model Content

[0011] The utility model provides a safety brake device for a pneumatic motor, which has the following beneficial effects:

[0012] (1) The utility model provides a cylinder, an air inlet, an air outlet and a connecting port, and respectively connects the air inlet, the air outlet and the connecting port to an air source through a connecting pipe and an electromagnetic valve. When the motor needs to be braked, the air intake from the connecting port into the motor is reduced, and at the same time, air is taken into the cylinder through the air inlet, thereby assisting the sliding of the push plug until the push plug pushes the first brake pad toward the output end of the motor. The pneumatic motor is braked from two aspects at the same time, thereby accelerating the braking speed, reducing the loss caused by the friction between the output end of the motor and the brake pad, and extending the service life of the motor and the brake device.

[0013] (2) The utility model provides a first mounting tube, a second mounting tube, a first piston rod, a second piston rod, a slide, and a second brake pad, etc., so that when the first brake pad cannot completely brake the motor, the second brake pad is used to assist the first brake pad to brake the motor output end at the same time, thereby ensuring the braking effect of the braking device and avoiding braking failure; when air is introduced into the cylinder barrel through the air inlet and the air outlet, the push plug is pushed forward, and the first brake pad is pushed so that the first brake pad fits with the motor output end. If the motor is not completely braked, air is continuously ventilated into the cylinder barrel through the air inlet and the air outlet. The relatively high air pressure in the cylinder barrel pushes the first piston rod upward until the second mounting tube is exposed. Air is continuously ventilated, and the air pressure pushes the second piston rod to slide. The second piston rod pushes the slide to slide to the right, driving the second brake pad connected to the slide to approach the motor output end until it also fits with the motor output end, and cooperates with the first brake pad to brake the motor. This braking method ensures that the braking device still has a braking effect after the first brake pad fails after long-term use. BRIEF DESCRIPTION OF THE DRAWINGS
