Braking device

A braking device for braking a belt of a belt conveyor, the belt comprising a first belt surface and a second belt surface opposite to each other, and the braking device comprising:

• a first clamping plate;
• and
• a second clamping plate;
• wherein the first clamping plate is provided on a side of the first belt surface away from the second belt surface;
• the second clamping plate is provided on a side of the second belt surface away from the first belt surface;
• the first clamping plate and the second clamping plate are configured to move toward each other such that the second clamping plate abuts against the second belt surface and the first clamping plate abuts against the first belt surface, thereby clamping the belt to brake the belt;
• the first clamping plate and the second clamping plate are further configured to move away from each other to release the belt;
• the second clamping plate is configured to move toward or away from the first clamping plate to clamp the belt, or release the belt;
• the braking device further comprises a drive component;
• the drive component is connected to the second clamping plate, and configured to drive the second clamping plate to move toward or away from the first clamping plate;
• the braking device further comprises a box;
• two ends of the box in a lengthwise direction or a widthwise direction are each provided with an opening;
• the first clamping plate is provided inside the box;
• the second clamping plate is slidably provided in the box;
• the second clamping plate is configured to move toward or away from the first clamping plate along a height direction of the box;
• the belt is configured to pass between the first clamping plate and the second clamping plate through the opening;
• the braking device further comprises a first airbag;
• the first airbag is connected to a side of the first clamping plate away from the belt, and configured to provide cushion between the first clamping plate and the belt;
• and/or
• the braking device further comprises a second airbag connected to a side of the second clamping plate away from the belt, and the second airbag is configured to provide cushion between the second clamping plate and the belt.
