1. Overview
The pneumatic vehicle blocking beam is a device used to prevent rolling stock during mine inclined tunnel transportation. The device uses gas power to lift the blocking beam, which is labor-saving, smooth, safe and reliable, and provides safe protection for inclined lane transportation. This product is exported to coal mining enterprises all over the country and has broad promotion prospects.
2. Working Principle
This product is mainly composed of a cylinder, a car blocking beam, a pneumatic control box, etc. The pneumatic blocking beam is a normally closed blocking device. When a mine car passes, the reversing valve is operated to make the cylinder The piston rod contracts, and the wire rope pulls the blocking beam to rise. After the mine car passes, the manual reversing valve is operated. The compressed air enters the working chamber of the cylinder through the pipeline to extend the piston rod. The blocking beam falls back to the closing position of the blocking beam under the action of its own weight. Location.
