The sliding arm 10 is movably connected to the vehicle frame 1 along the first direction, and the two sliding arms 10 are respectively provided on both sides of the vehicle frame 1 along the first direction. Each group of support arms 5 is respectively connected to one sliding arm 10. The driving component includes a moving part 7 and two connecting arms 8. The two connecting arms 8 are respectively provided on both sides of the moving part 7 along the first direction. The two connecting arms 8 are respectively connected to the two sliding arms 10.

[0027] The first direction may be the direction shown by the X-axis in the figure, and the second direction may be the direction shown by the Y-axis in the figure. The first direction and the second direction may be parallel to the horizontal direction.
[0028] The support arm 5 is used for installing and setting the lifting arm 9, and the lifting arm 9 is used for jacking up the vehicle frame 1.
[0029] A plurality of support arms 5 are respectively arranged on both sides of the vehicle frame 1 along the first direction, and in each group of support arms 5, each support arm 5 is arranged along the second direction, so that under the combined action of the lifting arms 9 of the plurality of support arms 5, the vehicle frame 1 can be stably jacked up.
[0030] The plurality of support arms 5 are movably connected to the vehicle frame 1 along the first direction, so that the position of the lifting arm 9 arranged on the support arm 5 relative to the vehicle frame 1 can be adjusted. During the drilling operation, it can be adjusted according to the terrain, increasing the adaptability of the drilling device in the embodiment of the present application.
[0031] Each group of support arms 5 is respectively connected to a sliding arm 10, so that one sliding arm 10 can drive the plurality of support arms 5 to move, simplifying the structure and facilitating the simultaneous driving of the plurality of support arms 5 to move.
[0032] When the driving part 7 is driven to move along the second direction, the connecting arm 8 rotates relative to the driving part 7, and then under the action of the connecting arm 8, the two sliding arms 10 can move along the first direction, so that the plurality of support arms 5 can be driven by one power source, which not only reduces the cost, but also simplifies the structure and can drive the plurality of support arms 5 to move synchronously.
[0033] In the embodiment of the present application, the specific structures of the support arm 5 movably connected to the vehicle frame 1 and the sliding part movably connected to the vehicle frame 1 can be selected from existing structures. For example, the sliding part can be movably connected to the vehicle frame 1 through a sliding groove 13.

The first hydraulic cylinder 14 is arranged on the vehicle frame 1, and the telescopic end 15 of the first hydraulic cylinder 14 moves along the second direction, and the telescopic end 15 is connected to the driving part 7.
[0035] When the telescopic end 15 of the first hydraulic cylinder 14 moves along the second direction, the telescopic end 15 can drive the driving part 7 to move along the second direction, and then the driving part 7 can drive the connecting arm 8 to rotate.
[0036] The structure and working principle of the hydraulic cylinder are well-known to those skilled in the art and will not be elaborated here.
[0037] In some embodiments, the moving part 7 includes two wall parts 17 oppositely arranged along the first direction, the telescopic end 15 is arranged between the two wall parts 17, and pin holes are respectively arranged on the telescopic end 15 and the two wall parts 17, and a pin 16 is inserted through the pin holes.
[0038] Under the action of the pin 16, the telescopic end 15 can be detachably connected to the wall part 17, that is, when the pin 16 is inserted through the pin holes of the wall part 17 and the telescopic end 15, the telescopic end 15 can be connected to the wall part 17. On the contrary, when the pin 16 is taken out from the pin hole, the telescopic end 15 can be removed from the moving part 7.

[0048] When the shaft body 12 is inserted into the shaft hole, since the cross-sections of the shaft body 12 and the shaft hole are both polygonal, the position of the second arm 4 relative to the first arm 3 is locked at this time. When the shaft body 12 is taken out of the shaft hole, the second arm 4 can rotate relative to the first arm 3.
[0049] The cross-sectional shapes of the shaft body 12 and the shaft hole can be set as needed. For example, they can be a regular hexagon, a regular octagon, or a regular hexadecagon, etc.
[0050] In some embodiments, the second arm 4 includes two support portions 6 arranged oppositely along the third direction, and the first arm 3 is arranged between the two support portions 6.
[0051] The first arm 3 is arranged between the two support portions 6, and the two support portions 6 increase the connection strength between the second arm 4 and the first arm 3.

[0053] The leg portion 20 can be movably connected to the fixing portion 19 along the third direction.
[0054] The leg portion 20 is used to contact the ground. When the leg portion 20 moves away from the fixing portion 19, the vehicle frame 1 can be lifted.
[0055] In some embodiments, a second hydraulic cylinder 23 is detachably arranged on the fixing portion 19. The second hydraulic cylinder 23 is detachably connected to the fixing portion 19, and the telescopic portion of the second hydraulic cylinder 23 is detachably connected to the leg portion 20.
[0056] When the telescopic portion of the second hydraulic cylinder 23 extends or retracts, the leg portion 20 can move under the drive of the telescopic portion to lift or lower the vehicle frame 1.
[0057] The telescopic portion of the second hydraulic cylinder 23 is detachably connected to the leg portion 20, and the second hydraulic cylinder 23 is detachably connected to the fixing portion 19, so that the second hydraulic cylinder 23 can be detached from the lifting arm 9, which is convenient for maintaining the second hydraulic cylinder 23.
