Embodiment Construction

[0045] Such as figure 1 , 3 , 5, an automatic rod changing device for a drilling rig, comprising a drill rod box 10, the wall of the drill rod box 10 is provided with a rod sending motor A50, a rod sending motor B60, a delivery cylinder 20, a rod receiving cylinder A40, a rod receiving Cylinder B70.

[0046] Such as figure 2 , the interior of the drill rod box 10 is divided into a normal warehouse 11 and a turnover warehouse 12 that are connected to each other. A discharge bracket 131 is fixed on the wall of the drill rod box 10. The space wrapped by the discharge bracket 131 is the delivery warehouse 13, the turnover warehouse 12 communicates with the delivery bin 13. The meaning of the connection is "the drill pipe can be moved from one bin to another bin". The normal bin 11 is provided with multiple rows of drill pipes 90 parallel to the turnover bin 12, and each row of drill pipes 90 includes There are a plurality of drill pipes 90 , the turnover bin 12 is a single row...

Abstract

The invention provides an automatic rod changing device for a drill carriage. The automatic rod changing device comprises a drill rod box, wherein a rod feeding motor A, a rod feeding motor B, a conveying oil cylinder, a rod collecting oil cylinder A and a rod collecting oil cylinder B are arranged on the box wall of the drill rod box; the inner part of the drill rod box is divided into a normal bin and a turnover bin which are communicated with each other; a discharging bracket is fixed on the box wall of the drill rod box; a space wrapped by the discharging bracket is a conveying bin; the turnover bin is communicated with the conveying bin; a plurality of rows of drill rods parallel to the turnover bin are arranged in the normal bin; each row of drill rods comprises a plurality of drill rods. Compared with the prior art, the automatic rod changing device has the technical effects that the drill rod box capable of synchronously rotating with a drilling machine frame is arranged, and the automatic rod changing device does not depend on the gravity of the drill rods but depends on power equipment for feeding and collecting the rods, so that the rod feeding and collecting operation of the drill rod box can be realized at any angle, a drill rod inclination angle adjusting part is not needed, and the rod changing operation is facilitated.

Description

technical field [0001] The invention relates to an automatic rod changing device for a drilling rig and methods for sending and receiving rods. Background technique [0002] At present, during the drilling process, drilling equipment such as drilling rigs and drilling trucks need to replenish new drill pipes in a timely and rapid manner due to their continuous penetration into the ore seam. At this time, the rod changing device is required to continuously provide new drill pipes. [0003] During the drilling process, the drilling angle is also uncertain (the angle of each drilling is different), the opening direction of the drill pipe box is upward, and generally does not rotate synchronously with the drilling rig frame. Slips inside the rod box. [0004] Therefore, when the rod changing device replaces the drill rods, the inclination angle of the drill rods needs to be adjusted once after the drill rods are taken out of the drill rod box, so that the drill rods can be alig...
