DESCRIPTION

The barb of bolt tray can be positioned in the drilled hole, and the rod body is well centered. The bolt tray is one of the parts of the pipe joint bolt, its material is made of welded ring and rolled head, and the ring cutting is made to make the retaining ring. The cutting plate, punching type and punching hole are made for the tray, the rod body and the retaining ring. There are many types of anchor trays, and there are mainly butterfly trays and plate trays in the mine. The effect of the butterfly is better than the flat tray.
Application: As an important part of the bolt support system, the bolt pallet has a direct effect on the supporting effect of the bolt. Tray is the role of the lock nut tightening torque generated by the thrust is transmitted to help, at the beginning of the anchor force, at the same time, the pressure of the roadway roof will help to anchor, working resistance, common reinforcement of surrounding rock, prevent displacement of the roadway roof to help. So when choosing a tray, the first is to satisfy the match of the bolt and the bolt body on the strength, to avoid the bolt hole caused by the insufficient strength of the bolt tray. The second is to satisfy the bolt and anchor rod on the supporting structure of the match, avoid the anchor rod body with the tray on the supporting structure caused by the mismatch anchor rod body and the nut uneven, influence of roadway supporting effect.
Material: Q235, Q345
Specification: 150*150*10, 150*150*8, 140*140*10, 140*140*8, 120*120*8, 120*120*10.
Characteristic: The product is a supporting plate for mine roadway and tunnel, especially in coal mine roadway. The center of the pallet has holes for the bolt to pass through, the central part is a hollow spherical bulge, there is a platform at the top of the dome, pallets can be made of steel or cast iron, and cast iron brackets can be reinforced around the ball. The high quality ore tray improves the internal stress state of the anchor plate, which has the advantages of strong bearing capacity and saving material.
