Anchor rod trolley and anchor rod mechanism thereof

Abstract

The invention discloses an anchor rod mechanism of an anchor rod trolley. The anchor rod mechanism comprises an anchor rod unit, wherein the anchor rod unit comprises a propelling beam, a rotating shaft, a drilling assembly, a grouting assembly and an anchor rod assembly; the propelling beam is rotatably arranged on the rotating shaft, the rear end of the propelling beam is used for being connected with an arm frame of the anchor rod trolley, and the arm frame can drive the propelling beam to rotate around the axis of the rotating shaft in a fixed-axis mode; a center structure is arranged at the front end of the rotating shaft, located at the foremost end of the working face of the anchor rod unit and used for being pressed and located on the tunnel face of an anchor rod hole to be constructed; and the axis of a drill rod of the drilling assembly, the axis of a grouting pipe of the grouting assembly and the axis of an anchor rod of the anchor rod assembly are parallel to the axis of the rotating shaft at equal intervals. According to the anchor rod mechanism, drilling operation, grouting operation and anchor rod inserting operation are all automatically completed by the anchor rod mechanism, and participation of operators is reduced, so that the operation safety risk is greatly reduced, and the construction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a bolt trolley and a bolt mechanism thereof. Background technique [0002] Bolt support is a reinforcement and support method used in the construction of underground spaces such as tunnels and stopes. The mechanical state of the surrounding rock itself is changed by the bolt driven into the surrounding rock, and an integral and stable rock belt is formed. , using the joint action of the anchor rod and the surrounding rock to achieve the purpose of maintaining the stability of the roadway. Most of the existing rock bolt trolleys have realized the integration of drilling, anchoring and grouting, but they generally need manual operation to find holes during the construction process. This method not only takes a long time to find holes, but also cannot guarantee the safety of operators. Therefore, , in the actual working process of the current bolt mechanism, there ar...
