Three-row anchor rod construction marking system for double-arm hydraulic anchor rod drill carriage

Abstract

The invention relates to a three-row anchor rod construction marking system for a double-arm hydraulic anchor rod drill carriage. The system comprises a marking assembly, the marking assembly is used for spraying cross marks on the surfaces of a roadway top plate and two sides, the marking assembly comprises a first telescopic arm, a swing arm assembly and a spraying assembly, one end of the first telescopic arm is mounted on the upper surface of the front part of a working platform, the other end of the first telescopic arm is provided with a swing arm assembly, the swing arm assembly is adjusted in a 180-degree vertical plane in a reciprocating swing mode, the end of the first telescopic arm is provided with a gear box, the gear box is used for adjusting the pitching angle of a second telescopic arm in the longitudinal vertical plane, and the surface of the working platform is further provided with a controller, a control valve body and a hydraulic pump. According to the system, the control valve body is automatically controlled through the controller, a first hydraulic rotor, a second hydraulic rotor, a rotating oil cylinder, the first telescopic arm and the second telescopic arm are further automatically controlled by the controller, and construction marking of three rows of anchor rods on the roadway top plate and two sides can be achieved.

Description

technical field [0001] The invention relates to the field of bolt construction, in particular to a three-row bolt construction marking system for a double-arm hydraulic rock bolt drilling vehicle. Background technique [0002] In modern coal mine bolting operations, in order to reduce labor intensity, reduce potential safety hazards, and improve tunneling efficiency, double-arm hydraulic bolting rigs have been widely used in modern coal mine operations, while manual operations are carried out through pneumatic bolting rigs. The operation method of support and anchoring has gradually become an auxiliary operation for coal mine bolting operations. The double-arm hydraulic rock bolter can realize 360° drilling without dead angle through the rotating cylinder, which meets the needs of all-round drilling operations in the roadway. The double-arm hydraulic The parking position of the anchor drilling rig is not very demanding. The relative position can be adjusted through the two d...
