Problems solved by technology

Existing open-type roadheaders only have functions such as section monitoring, and have not really realized automatic cutting footage and support, which will seriously affect the speed of excavation footage. The slow support has always been the main factor affecting the excavation footage. It is almost Occupies 2 / 3 of the tunnel footage time

Abstract

The invention discloses an automatic drilling bolt mechanical arm device mounted on a roadheader. It is hinged with the fixed support, and the auxiliary manipulator is fixedly connected to the main manipulator. The auxiliary manipulator includes two slide rails, a drilling rig hydraulic rod and a chute. The two slide rails are arranged on both sides of the auxiliary manipulator arm. There is a feeding mechanism on the top, the chute is set at the upper end of the auxiliary mechanical arm, the hydraulic rod of the drilling rig is fixed at the end of the chute, the bolting rig is fixed on the drilling rig trolley, and the bottom of the drilling rig trolley is provided with a pulley, and the pulley is slidably arranged on the slide. In the groove, the hydraulic rod of the drilling rig is connected with the trolley of the drilling rig. Several anchor rods are placed in the anchor rod storehouse. The anchor rod storehouse is fixed above the chute, and the gap between the anchor rod storehouse and the anchor rod drilling rig is set. The automatic drilling anchor rod of this scheme The robotic arm device has a high degree of automation, which can significantly speed up the tunnel support.

Description

technical field [0001] The invention relates to the field of bolt construction, in particular to an automatic drilling and bolt mechanical arm device mounted on a boring machine. Background technique [0002] The new Austrian method is to carry out full-section excavation construction on the premise of utilizing the bearing capacity of the surrounding rock itself, and build the tunnel body by forming a composite inner and outer two-layer lining, that is, using shotcrete and bolt support , steel mesh, steel support, etc. are the outer support forms, called the initial support, which must be carried out immediately after the excavation of the cave body. Because the ground stress hidden in the mountain is redistributed due to the excavation into holes, the tunnel space is kept stable by the cavitation effect, that is to say, the surrounding rock mass itself mainly bears the ground stress, and the primary sprayed anchor flexible support The role of the second lining is to maxim...
