specific Embodiment approach

[0024] Referring to the accompanying drawings, the specific implementation is as follows:

[0025] The invention provides a method for adding rods in the middle of a guide rail type drilling device. The guide rail type drilling device includes a section of guide rail 1, on which a power head 2 for clamping a drill pipe 5 is installed, and the power head 2 is far away from the hole to be drilled. A cooling water input device 3 is installed on one side of the wall. When the stroke of the power head 2 moving on the guide rail 1 is less than the length of the drill rod 5, it is difficult to add intermediate rods to the drill rod 5. In this embodiment, the intermediate rod addition to the drill rod 5 can be realized through the following method steps:

[0026] Step 1. Drill pipe installation

[0027] Such as Figure 1-2 As shown, the holder 4 is pre-installed between the guide rail 1 of the drilling device and the wall to be drilled, usually the holder 4 is directly placed on the...

Abstract

The invention discloses a middle rod adding method of a guide rail type drilling device. The method comprises the steps that a clamp holder is installed between a guide rail and a wall surface of thedrilling device, a common rod is clamped to a power head of the drilling device, then the tail of a drill rod is connected with the head of the common rod, and then the power head moves to be close tothe wall surface to be drilled; the drill rod is driven by the power head to rotate, and after penetrating through the clamping hole of the clamp holder, the head of the drill rod starts to drill a hole in the wall surface; after the power head moves to the limit position close to the wall surface, the power head stops driving the drill rod to rotate, then the clamp holder clamps the drill rod, the power head loosens the common rod, then the power head reversely moves along the guide rail and is far away from the drilled wall surface, then the tail of the common rod is clamped through the power head, and the clamp holder loosens the drill rod; and then the power head moves again to be close to the wall face to be drilled, the drill rod is continuously driven to rotate through the power head, the drill rod continuously drills into the wall face, and therefore the effect of adding the rod in the middle when the pushing stroke of the power head is smaller than the length of the drill rodis achieved.

Description

technical field [0001] The invention relates to the field of drilling methods of a guide rail type drilling device, in particular to a middle rod adding method of a guide rail type drilling device. Background technique [0002] Most of the conventional rail-type drilling devices use a rear reducer to add rods, and the drill rod passes through the inside of the reducer power head, and the drill rod is clamped by the power head to rotate and advance to realize the drilling of the equipment. This method of adding rods is simple and practical, but when adding drill pipes, the water delivery device at the end of the drill pipe needs to be frequently disassembled, and when the space at the end of the guide rail is limited, the requirements for installing drill pipes cannot be met. The middle adding method of placing the drill pipe between the power head and the drilling wall. [0003] However, the method of adding rods in the middle is limited by the stroke of the guide rail, tha...
