Anchor tray product role

As an important part of the anchor support system, the performance of the anchor tray directly affects the support effect of the anchor. The role of the tray is to transfer the thrust force generated by the nut locking torque to the top gang to produce the initial anchor force, and at the same time, the pressure of the roadway top gang is transferred to the anchor rod to produce the working resistance, which jointly reinforces the surrounding rock and prevents the displacement of the roadway top gang. Therefore, when selecting the tray, firstly, it is necessary to satisfy the matching of the anchor tray and the anchor rod body in terms of strength, so as to avoid the phenomenon of anchor perforation caused by the insufficient strength of the anchor tray. The second is to meet the matching between the anchor tray and the anchor rod body in the support structure, to avoid the uneven force on the anchor rod body and nut due to the mismatch between the anchor rod body and the tray in the support structure, which affects the support effect of the roadway.
