Background
Most of conventional guide rail type drilling devices adopt a rear speed reducer to add a rod, a drill rod penetrates through a power head of the speed reducer, and the drill rod is clamped by the power head to be rotationally pushed, so that drilling of equipment is realized. The rod adding method is simple and practical, but the tail end water feeding device of the drill rod needs to be frequently disassembled and assembled when the drill rod is added and connected, and the requirement of adding the drill rod cannot be met when the space at the tail end of the guide rail is limited, so that a middle rod adding mode of placing the drill rod between a power head of the speed reducer and a drilling wall surface can be adopted.
However, the mode of adding the rod in the middle is limited by the travel of the guide rail, namely, the total length of the rod extending out of the power head of the speed reducer after the drill rod is clamped cannot exceed the travel of the power head of the speed reducer on the guide rail, and if the length of the drill rod exceeds the travel of the guide rail, a space for placing the drill rod is difficult to reserve between the power head of the speed reducer and the wall surface of a drill hole. Therefore, the prior art lacks a method for realizing the middle rod adding of the drill rod when the propelling stroke of the power head is less than the length of the drill rod.

Detailed Description
Referring to the drawings, the specific embodiments are as follows:
the invention provides a middle rod adding method of a guide rail type drilling device, wherein the guide rail type drilling device comprises a section of guide rail 1, a power head 2 for clamping a drill rod 5 is arranged on the guide rail 1, and a cooling water input device 3 is arranged on one side, far away from a wall surface to be drilled, of the power head 2. When the travel 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 perform intermediate rod adding on the drill rod 5, and the present embodiment can perform intermediate rod adding on the drill rod 5 by the following method steps:
step one, drill rod installation
As shown in fig. 1-2, a holder 4 is previously installed between a guide rail 1 of a drilling apparatus and a wall surface to be drilled, and the holder 4 is generally directly placed on the ground between the guide rail 1 and the wall surface; clamping a public rod 6 to a power head 2 of a drilling device, ensuring that the tail of the public rod 6 extends into the power head 2 and clamping the public rod 6 through the power head 2, sleeving a baffle 7 on the public rod 6, enabling the baffle 7 to be close to the head of the public rod 6, and limiting the distance of the tail of the public rod 6 extending into the power head 2 through the baffle 7; and then the tail part of the drill rod 5 is connected with the head part of the common rod 6, so that the axis of the drill rod 5 is coincident with the axis of the common rod 6.
Step two, one-time feeding
As shown in fig. 3, after the drill rod 5 is installed, the power head 2 is moved along the guide rail 1 and is close to a wall surface to be drilled, the power head 2 drives the common rod 6 and the drill rod 5 to rotate, the head of the drill rod 5 firstly passes through the clamping hole of the clamp 4 during feeding, and then drilling is started on the wall surface until the power head 2 moves to the limit position close to the wall surface along the guide rail 1, namely the position of the power head 2 in fig. 3.
Step three, returning and re-clamping
As shown in fig. 4, after the power head 2 moves to the extreme position close to the wall surface along the guide rail 1 shown in fig. 3, the power head 2 stops moving and stops driving the common rod 6 and the drill rod 5 to rotate, then the clamping hole of the clamp holder 4 clamps the drill rod 5, the power head 2 loosens the common rod 6, then the power head 2 moves reversely along the guide rail 1 and keeps away from the drilled wall surface, when the reverse movement of the power head 2 stops, the tail of the common rod 6 is still positioned inside the power head 2, then the tail of the common rod 6 is clamped by the power head 2, the clamp holder 4 loosens the drill rod 5, the power head 2 reversely returns after once feeding, and then the drill rod 5 is clamped again.
Step four, feeding again
As shown in fig. 5, after the common rod 6 is clamped again, the power head 2 is driven to move along the guide rail 1 and is close to the wall surface to be drilled again, the power head 2 continues to drive the common rod 6 and the drill rod 5 to rotate, the drill rod 5 continues to drill into the wall surface, and compared with the position in fig. 3, the length of the drill rod 5 extending out of the power head 2 can be increased inevitably, so that the middle rod adding of the drill rod 5 is realized, the condition that the middle rod adding of the drill rod 5 cannot be carried out due to the short stroke of the guide rail 1 is avoided, the operation is simple and convenient, and the popularization and the application are facilitated.
