A drilling machine according to an embodiment of the present invention is described hereinafter with reference to FIG. 1 to FIG. 10. The drilling machine mentioned in the present invention may be a down-the-hole drilling machine or other common drilling machines needing to use a drill pipe.

A drilling machine according to an embodiment of the present invention, as shown in FIG. 1 to FIG. 10, comprises a machine body 100, a drill pipe warehouse 200, a propeller 300, a drill pipe temporary placing mechanism 400, a drill pipe carrying mechanism 500 and a drill pipe loading and unloading mechanism 600. The machine body 100 is provided with a drill boom 101, the drill pipe warehouse 200 is arranged on the machine body 100 and used for storing a drill pipe, the propeller 300 is arranged at a tail end of the drill boom 101, the propeller 300 is provided with a power head 301 capable of rotating and moving in an aXial direction, the drill pipe temporary placing mechanism 400 is arranged on the propeller 300 or the tail end of the drill boom 101 and used for temporarily placing the drill pipe, the drill pipe carrying mechanism 500 is arranged on the drill boom 101 or the machine body 100 and used for carrying the drill pipe, and the drill pipe loading and unloading mechanism 600 is arranged on the propeller 300 or the tail end of the drill boom 101 and used for _7_ transferring the drill pipe to a moving path of the power head 301 and centering the drill pipe to the power head 301. When the drill pipe needs to be mounted, the drill pipe is removed from the drill pipe Warehouse 200 and placed on the drill pipe carrying mechanism 500, then the drill pipe is carried to the vicinity of the propeller 300 through the drill pipe carrying mechanism 500, and the drill pipe is finally mounted on the power head 301 of the propeller 300 through the drill pipe loading and unloading mechanism 600.

In the prior art, when the drill pipe needs to be mounted on the power head 301, the drill pipe is generally manually transferred to the moving path of the power head 301 and centered to the power head 301. Because the drill pipe is heavy and it is difficult to center the drill pipe to the power head 301 during manual operation, the mounting and disassembly processes are complicated, the workload and labor intensity are high, the operation efficiency is low, and the manual operation has great safety hazards. In the embodiment, the drill pipe loading and unloading mechanism 600 is provided. When the drill pipe needs to be mounted, the drill pipe is placed on the drill pipe loading and unloading mechanism 600, and then the drill pipe loading and unloading mechanism 600 is operated, so that the drill pipe loading and unloading mechanism 600 may transfer the drill pipe to the moving path of the power head 301 and center the drill pipe to the power head 301, and then the power head 301 is moved forward and rotated, so that the power head 301 may be threadedly connected with the drill pipe, thus mounting the drill pipe. Correspondingly, when the drill pipe is disas sembled, the drill pipe may also be removed from the moving path of the power head 301 through the drill pipe loading and unloading mechanism 600. Compared with manual mounting and disassembly of the drill pipe, the process is simpler, then the workload and the labor intensity are lower, the machining efficiency is higher, and the safety is better.

In addition, the drill pipe to be added may be carried to the vicinity of the drill pipe temporary placing mechanism 400 through the drill pipe carrying mechanism 500 during drilling, and the drill pipe may be placed on the drill pipe temporary placing mechanism 400. When the drill pipe needs to be added, it is only necessary to remove the drill pipe on the drill pipe temporary placing mechanism 400 and mount the drill pipe on the power head 301 through the drill pipe loading and unloading mechanism 600. Because the drill pipe temporary placing mechanism 400 is close to the power head 301, compared with temporarily carrying the drill pipe from the drill pipe warehouse 200, the time required for adding the drill pipe is shorter, and then the operation of the power head 301 is stopped for a shorter time, thus further improving the machining efficiency.

It should be noted that, in the prior art, the drill pipe warehouse 200 is mounted on the propeller 300 in some drilling machines to reduce carrying, but the mounting of the drill pipe warehouse 200 on the propeller 300 may lead to forward displacement of a whole center of gravity of the drilling _g_ machine. Therefore, in order to avoid the overturning of the drilling machine, not only the drill boom 101 is short, but also the drill pipe Warehouse 200 is small in Volume and can only store a few of drill pipes. According to the present invention, the drill pipe Warehouse 200 is arranged on the machine body 100, Which can avoid the above problem. The drill pipe Warehouse 200 is an equipment used for storing the drill pipe, and the drill pipe Warehouse 200 is not improved in the present invention, therefore a structure and a Working principle of the drill pipe Warehouse 200 are not repeated herein. The drill pipe temporary placing mechanism 400 may be arranged on the propeller 300 or a tail end of the drill boom 101, and What is only required is that the drill pipe on the drill pipe temporary placing mechanism 400 needs to be close to the poWer head 301. The poWer head 301 is a component used for controlling the movement and rotation of the drill pipe, the poWer head 301 is capable of moving along a rotating axis of the poWer head itself, and the moving path of the poWer head is generally no less than a length of the drill pipe. When the drill pipe is mounted, the poWer head 301 may be located in an initial position, and then the drill pipe is located on the moving path of the poWer head 301 and centered to the poWer head 301, that is, an axis of the drill pipe coincides With a rotating center of the poWer head 301. One end of the drill pipe close to the poWer head 301 is generally provided With an external thread, the poWer head 301 is generally correspondingly provided With a threaded hole, and then the threaded hole in the poWer head 301 may be connected With the extemal thread on the drill pipe by moving forWard and rotating the poWer head 301, so that the drill pipe is capable of being mounted on the poWer head 301. When the drill pipe needs to be disassembled, the drill pipe is temporarily fixed, and then the drill pipe is capable of being prevented from rotating along With the poWer head 301, and When the poWer head 301 is moved backWard and rotated reversely, the threaded hole in the poWer head 301 may be separated from the external thread on the drill pipe, so that the drill pipe is disassembled from the poWer head 301. The drill pipe carrying mechanism 500 may be arranged on the drill boom 101 or the machine body 100, as long as the drill pipe can be carried from the vicinity of the drill pipe Warehouse 200 to the vicinity of the propeller 300 or from the vicinity of the propeller 300 to the vicinity of the drill pipe Warehouse 200. The drill pipe loading and unloading mechanism 600 may be arranged on the propeller 300 or the tail end of the drill boom 101, as long as the drill pipe can be transferred to the moving path of the poWer head 301 and centered to the poWer head 301.

In some embodiments of the present invention, as shoWn in FIG. 2 to FIG. 5, the drill pipe loading and unloading mechanism 600 comprises a rotating shaft 601 and several loading and unloading jaWs 602. The rotating shaft 601 is arranged on the propeller 300, and the rotating shaft 601 is located on one side of the moving path of the poWer head 301 and parallel to a rotating axis of the poWer head 301. The loading and unloading jaW 602 is arranged on the rotating shaft 601, the _9_ loading and unloading jaw 602 is used for clamping the drill pipe, and during movement of the loading and unloading jaw 602 around an axis of the rotating shaft 601, the loading and unloading jaw can drive the drill pipe to move to the moving path of the power head 301 and centers the drill pipe to the power head 301. The propeller 300 may be provided with a second mounting frame 302, the rotating shaft 601 may be rotatably mounted on the second mounting frame 302, after the drill pipe is clamped by the loading and unloading jaw 602, the drill pipe is parallel to the rotating shaft 601, and a distance between the axis of the drill pipe and the axis of the rotating shaft 601 is approximately equal to a distance between the moving path of the power head 301 and the axis of the rotating shaft 601. Therefore, when the rotating shaft 601 is rotated, the loading and unloading jaw 602 can just drive the drill pipe to move to the moving path of the power head 301 and center the drill pipe to the power head 301, thus being simple in structure and convenient to operate. It should be noted that the rotating shaft 601 may also be arranged at the tail end of the drill boom 101. In addition, the drill pipe loading and unloading mechanism 600 may also be other structures, such as a sliding frame slidably mounted on the propeller 300, wherein the sliding frame is provided with a jaw used for clamping the drill pipe, and the sliding frame may drive the drill pipe to move to the moving path of the power head 301 and center the drill pipe to the power head 301 by sliding the sliding frame. The second mounting frame 302 may also be provided with a swinging oil cylinder or a driving motor, an output shaft of the swinging oil cylinder or the driving motor is in transmission connection with the rotating shaft 601, and the rotating shaft 601 may be driven to rotate by starting the swinging oil cylinder or the driving motor. One or more loading and unloading jaws 602 may be provided, for example, two loading and unloading jaws may be provided. When a plurality of loading and unloading jaws 602 are provided, the plurality of loading and unloading jaws 602 are arranged on the rotating shaft 601 in the axial direction of the rotating shaft 601 and located on the same side of the rotating shaft 601, and the plurality of loading and unloading jaws 602 are coordinated to clamp the drill pipe. When one loading and unloading jaw 602 is provided, a contact area between the loading and unloading jaw 602 and the drill pipe may be large, so that the drill pipe can be tightly clamped. The loading and unloading jaw 602 may comprise a fixed clamping portion, a movable clamping portion and a control oil cylinder. The fixed clamping portion is arranged on the rotating shaft 601, the movable clamping portion is rotatably mounted on the fixed clamping portion, a first clamping space 603 capable of being opened and closed is formed between the fixed clamping portion and the movable clamping portion, and the control oil cylinder is arranged between the fixed clamping portion and the movable clamping portion to control the movable clamping portion to rotate. Certainly, the loading and unloading jaw 602 may also be other common jaw structures capable of clamping the drill pipe. The second mounting frame 302 may be provided with a restricting member 303, when the loading and _10- unloading jaw 602 drives the drill pipe to move to the moving path of the power head 301 and centers the drill pipe to the power head 301, the restricting member 303 abuts against a front end of a moving direction of the loading and unloading jaw 602, and then the drill pipe can be prevented from moving continuously, so that not only the drill pipe can be kept in a state of being centered to the power head 301, but also the drill pipe can be prevented from colliding with the propeller 300 to cause damage.

In some embodiments of the present invention, as shown in FIG. 2 and FIG. 5, the drill pipe temporary placing mechanism 400 comprises several clamps 401 arranged on the propeller 300, the clamp 401 is used for clamping the drill pipe, and when the loading and unloading jaw 602 moves around the aXis of the rotating shaft 601 to a set position, the drill pipe clamped by the clamp 401 can be located in the loading and unloading jaw 602. With the progress of drilling, new drill pipes need to be added periodically to increase a drilling depth. Specifically, when the drill pipe needs to be added, the power head 301 is moved backward and rotated reversely, so that the power head 301 is separated from the drill pipe and moved to an initial position, and then the new drill pipe is mounted between the power head 301 and the drill pipe closest to the power head 301. In the embodiment, the drill pipe to be added may be clamped by the clamp 401 in advance during drilling. When the drill pipe needs to be added, the rotating shaft 601 is rotated, so that the loading and unloading jaw 602 moves around the aXis of the rotating shaft 601 to the set position, and the new drill pipe clamped by the clamp 401 may be located in the loading and unloading jaw 602. Then, the new drill pipe is released by the clamp 401, and clamped by the loading and unloading jaw 602, and then the rotating shaft 601 is rotated, so that the loading and unloading jaw 602 may drive the new drill pipe to move to the moving path of the power head 301 and center the new drill pipe to the power head 301. Finally, the new drill pipe can be added, thus being convenient to operate and saving time and labor. It should be noted that the drill pipe temporary placing mechanism 400 may also be other structures, such as a placing frame arranged on the propeller 300 or the tail end of the drill boom 101, wherein the placing frame is provided with a placing groove for temporarily placing the drill pipe. The clamp 401 may also be arranged on the second mounting frame 302, and one or more clamps 401 may be provided, for example, two clamps may be provided. When a plurality of clamps 401 are provided, the plurality of clamps 401 may be arranged in a straight line, with an arrangement direction parallel to an arrangement direction of the plurality of loading and unloading jaws 602, and the plurality of clamps 401 are coordinated to clamp the drill pipe. When one clamp 401 is provided, a contact area between the clamp 401 and the drill pipe may be large, so that the drill pipe can be tightly clamped. After the drill pipe is clamped by the clamp 401, the drill pipe may be parallel to the rotating shaft 601, a distance between the aXis of the drill pipe and the aXis of the rotating shaft 601 may be approximately equal to a distance between the first clamping space 603 of the loading and unloading jaw 602 and _11- the aXis of the rotating shaft 601, and the loading and unloading jaw 602 moves around the aXis of the rotating shaft 601 to the set position, that is, the loading and unloading jaw moves to a position where the drill pipe clamped by the clamp 401 can be located in the first clamping space 603.

In some embodiments of the present invention, as shown in FIG. 5, the loading and unloading jaw 602 is provided with the first clamping space 603, the first clamping space 603 is provided with a first opening 604 for the drill pipe to enter and withdraw. When the first clamping space 603 moves around the aXis of the rotating shaft 601, the first opening 604 is located at a front end or a back end of a moving direction of the first clamping space 603. The clamp 401 is provided with a second clamping space 402, the second clamping space 402 is provided with a second opening 403 for the drill pipe to enter and withdraw, and the second opening 403 is located on a moving path of the drill pipe clamped by the loading and unloading jaw 602 around the aXis of the rotating shaft 601. Specifically, when the rotating shaft 601 is rotated to drive the loading and unloading jaw 602 to be far away from the moving path of the power head 301, the first opening 604 is located at the back end of the moving direction of the first clamping space 603. In this case, the drill pipe mounted on the power head 301 can just be separated from the first clamping space 603 of the loading and unloading jaw 602 through the first opening 604, thus mounting the drill pipe, and being simple in process and convenient to operate. When the rotating shaft 601 is rotated reversely to drive the loading and unloading jaw 602 to be close to the moving path of the power head 301, the first opening 604 is located at the front end of the moving direction of the first clamping space 603. In this case, the drill pipe mounted on the power head 301 can just enter the first clamping space 603 through the first opening 604, and then the drill pipe is tightly clamped by the loading and unloading jaw 602, so that the power head 301 may be conveniently separated from the drill pipe subsequently, thus being simple in process and convenient to operate. In addition, when the drill pipe is released by the clamp 401, and the drill pipe is tightly clamped by the loading and unloading jaw 602, the rotating shaft 601 is rotated, so that the rotating shaft 601 drives the loading and unloading jaw 602 to move, the loading and unloading jaw 602 drives the drill pipe to move, and the drill pipe may be withdrawn from the second clamping space 402 of the clamp 401 through the second opening 403, thus facilitating the addition of the drill pipe and being simple to operate. It should be noted that the first clamping space 603 is a space of the loading and unloading jaw 602 for accommodating the drill pipe, and when the drill pipe is located in the first clamping space 603, the first opening 604 is located on one side of the drill pipe.
