Embodiment Construction

[0014] The dual shaft drilling rig of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation.

[0015] refer to figure 1 As shown in , the duplex shaft drilling rig includes two drill stands 2, connecting mechanism 3, rock drilling mechanism 4, hydraulic pressure and air supply system.

[0016] The duplex shaft drilling rig is rigidly connected to the other drilling frame 2 through a liftable connection mechanism 3 installed on one of the drilling frames 2 . The drill frame 2 supports and connects a rock drilling mechanism 4, and is driven by the power of the hydraulic system to move the rock drilling mechanism 4 in parallel. Described drill frame 2 comprises column 22, the swing frame 21 that is installed on this column 22 movably, one end is connected with swing frame 21, and the other end is then connected with the swing arm 5 of rock drilling mechanism 4, and one end is installed on column ...

Abstract

The invention relates to a dual shaft-well drill which comprises two drilling rigs, a connection mechanism for connecting the two drilling rigs, a rock drilling mechanism and a hydraulic and air supply system connected with each drilling rig. The drilling rig comprises an upright column, a swing frame movably mounted on the upright column, a movable arm with one end mounted on the swing frame and the other end mounted on the rock drilling mechanism, and a support arm with one end mounted on the upright column; the rock drilling mechanism comprises a sliding frame, a compensation frame mounted on the sliding frame, a rock driller mounted on the sliding frame, and a drilling tool mounted on the rock driller. During operation, the two drilling rigs are in rigid connection with each other, and then the support arm of each drilling rig extends out to support the shaft wall and ensures the drilling rigs to be stabilized in the well, the rock drilling mechanism moves to the drill pore position in translation manner along with the movable arms and is driven by the auxiliary hydraulic system and air supply to drill rock. The dual shaft-well drill has the advantages that: the construction demands of large diameter shaft well are met, the moving speed is high, the productivity is high and the work intensity is greatly reduced for workers.

Description

technical field [0001] The invention relates to a drilling rig, in particular to a duplex drilling rig suitable for large-diameter shaft construction. Background technique [0002] With the rapid development of the national economy, the demand for metal materials in various industries across the country is increasing day by day. And because a large amount of metal mine engineering volume has been transferred from open pit to underground mining, the engineering volume of metal mine shaft construction is also growing rapidly. Although the engineering volume of metal mine shaft construction is increasing, the rock drilling equipment used for metal mine shaft construction has not been updated in time with the increase in shaft construction engineering volume, and its equipment technology is still relatively backward. [0003] At present, domestic metal mine shaft rock drilling construction mostly adopts pneumatic rock drill as the shaft drilling rig of drilling machinery. Comp...
