[0025] like Figures 2 to 4 As shown, the rotary drilling rig for railway piles includes a frame 11 and an upper vehicle 13 of the rotary drilling rig, the frame 11 includes a bottom frame 111, a train wheel 112 and a first slewing support flange 113, the train wheel 112 is connected to a side of the bottom frame 111 close to the ground, the train wheel 112 can make the frame 11 move on the rail 14 of the railway, the first slewing support flange 113 is fixedly connected to a side of the bottom frame 111 away from the ground, the bottom frame 111 is provided with a mounting groove, and the first slewing support flange 113 is arranged in the mounting groove The first slewing support flange 113 is welded on the base frame 111, and the upper car 13 is provided with a second slewing support flange 131. The first slewing support flange 113 cooperates with the second slewing support flange 131 to make the upper car 13 detachably connected to the frame 11, so that the upper car 13 can be switched between the track frame 21 and the frame 11. When it is not necessary to perform construction work on the railway, the upper car 13 is disassembled from the frame 11 and installed on the track frame 21, and the construction function can be performed under normal working conditions. The first slewing support flange 113 and the second slewing support flange 131 in the present invention are connected by bolts. Because the force at the slewing support is large, the reliability of bolt connection is higher. There are four train wheels 112 or eight train wheels 112. When there are four train wheels 112, the rotary drilling rig can be used in the 20-ton class. When there are eight train wheels 112, the rotary drilling rig can be used in the 40-ton class or 60-ton class.

[0026] The frame 11 of the rotary drilling rig of the present invention is connected to the second swivel support flange 131 of the upper car 13 through the first swivel support flange 113, so as to realize the connection between the frame 11 and the upper car 13. The frame 11 is provided with train wheels 112, so that the rotary drilling rig can move on the rail 14 of the railway, and use the idle period of the railway train to carry out pile work, so as to meet the requirements of pile construction along the railway. When the train passes normally, the rotary drilling rig can be moved to the ramp to give way to the train. In addition, when the rotary drilling rig of the present invention is not used in railway working conditions, the first swivel support flange 113 and the second swivel support flange 131 are disassembled, and the second swivel support flange 131 of the upper car 13 is connected to the crawler frame 21, so that it can be used in conventional working conditions. It has a simple structure, is easy to switch, has strong versatility, and can meet the needs of different products or different working conditions.

[0027] Preferably, the frame 11 also includes an outrigger cylinder 116, which is connected to the base frame 111. When the rotary drilling rig is in a transport state, the outrigger cylinder 116 is retracted. When the rotary drilling rig needs to work or reaches its destination, the outrigger cylinder 116 is lowered to make the outrigger cylinder 116 contact the ground. The outrigger cylinder 116 supports the base frame 111 to make the train wheels 112 leave the track 14, so that the rotary drilling rig can temporarily leave the track 14. Since the supporting surface of the conventional crawler frame 21 is large, when it is replaced with the train frame 11, its supporting surface is smaller than the supporting surface of the crawler frame 21. Therefore, the outrigger cylinder 116 is needed to support the upper vehicle 13 so that the outrigger cylinder 116 can provide a stable working base surface for the upper vehicle 13. There are four outrigger oil cylinders 116, each of which is arranged close to the first swivel support flange 113, and each of which is fixedly connected to a side of the base frame 111 close to the ground. After the first swivel support flange 113 is connected to the second swivel support flange 131, the swivel support exerts a greater force on the upper vehicle 13. Therefore, the outrigger oil cylinders 116 are arranged around the first swivel support flange 113 to increase the force stability of the frame 11.

[0028] Preferably, the frame 11 further includes a first coupler 114, which is connected to one end of the base frame 111 and can be detachably connected to the power locomotive head. When the rotary drilling rig is in a transport state, the first coupler 114 is connected to the power locomotive head, which is generally driven directly or through a transmission device by a power machine such as a steam engine, a diesel engine, a gas turbine, or a traction motor, and the power locomotive head can drive the frame 11 to drive the upper vehicle 13 to move on the track 14. The frame 11 further includes a second coupler 115, which is connected to the other end of the base frame 111 and can be detachably connected to the power locomotive head. In this embodiment, the power locomotive is connected to the first coupler 114 or the second coupler 115 according to the different driving directions, that is, the driving direction when the power locomotive is connected to the first coupler 114 is opposite to the driving direction when the power locomotive is connected to the second coupler 115. Since the frame 11 does not have a power device, the rotary drilling rig needs to be driven by the power locomotive to move on the track 14.

[0029] Preferably, the upper vehicle 13 also includes a mast assembly 132, and the mast assembly 132 is connected to the rotating platform of the upper vehicle 13. When the rotary drilling rig moves on the track 14, the mast assembly 132 can move with the upper vehicle 13, that is, the rotary drilling rig can be transported with the rod, and there is no need to hang the drill rod. When the rotary drilling rig needs to enter the working state, it only needs to erect the mast assembly 132 and adjust the mast amplitude to enter the working state. At the same time, the mast assembly 132 can also be quickly folded up at any time, and moved to the ramp by the power locomotive head to make way for normal trains, thereby improving the convenience of operation and improving work efficiency.

[0030] Preferably, the frame 11 in this embodiment retains the universality of the connection with the underframe 111, and the structure of the first slewing support flange 113 has the same flange as the track frame 21, so it is more convenient and quick to switch the upper vehicle 13 from the train frame 11 to the track frame 21, so that the upper vehicle 13 can be operated in conjunction with different underframes 111.

[0031] The present invention also relates to an operating method of a rotary drilling rig for the above-mentioned railway piles, the operating method comprising: The upper vehicle 13 of the rotary drilling rig is disassembled from the crawler frame 21 ; that is, the bolts of the slewing support between the upper vehicle 13 and the crawler frame 21 are disassembled.

[0032] The upper vehicle 13 of the rotary drilling rig is connected to the first swivel support flange 113 of the vehicle frame 11 through the second swivel support flange 131; the first swivel support flange 113 and the second swivel support flange 131 are connected by bolts.

[0033] The power locomotive is connected to the first coupler 114 or the second coupler 115 so that the power locomotive drives the rotary drilling rig to move to the destination on the track 14 .

[0034] The outrigger cylinders 116 are deployed to support the train wheels 112 of the rotary drilling rig to leave the track 14 , thereby providing a stable working base surface for the vehicle 13 .

[0035] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
