[0030] The usage method and advantages of the present utility model: When this kind of vehicle-mounted double-arm drill is in use, the working process is as follows:

[0031] As shown in the accompanying drawings of the specification Figures 1 to 6 shown, when the second hydraulic cylinder 5 expands and contracts, it will cause the transverse moving assembly 4 and the second connecting seat 3 to move back and forth around the first connecting seat 2;

[0032] As shown in the accompanying drawings of the specification Figure 3 As shown, the operation of the first hydraulic cylinder 42 will cause the output end of the first hydraulic cylinder 42 to drive the first transverse movement frame 41 and the second transverse movement frame 43 to move left and right. The connecting piece on the first transverse movement frame 41 will cause the limiting frame 70, the lifting frame 7, the hydraulic motor 13, and the core drill bit 14 to swing left and right around the center of the connecting piece on the output end of the third hydraulic cylinder 6; when the output ends of both the first hydraulic cylinder 42 and the third hydraulic cylinder 6 extend from the input ends for operation, it will cause the limiting frame 70, the lifting frame 7, the hydraulic motor 13, and the core drill bit 14 to undergo transverse movement. The swinging principle of the pile driver 15 here is the same as the above description and will not be elaborated further here;

[0033] When the output end of the fourth hydraulic cylinder 8 outputs from the input end, it causes the connecting piece on the fourth hydraulic cylinder 8 to jack up upwards, and at the same time drives the lifting frame 7, the hydraulic motor 13, and the core drill bit 14 to jack up synchronously. Through the lifting of the fourth hydraulic cylinder 8, the lifting of the hydraulic motor 13 and the core drill bit 14 is completed. The lifting principle of the pile driver 15 here is the same as the above description and will not be elaborated further here;

[0034] Turn on the fifth hydraulic cylinder 9. The operation of the fifth hydraulic cylinder 9 causes the chain 11 to work around the chain sprocket 10. The sliding block 12 on the chain 11 will drive the hydraulic motor 13 and the core drill bit 14 to descend. When the switch of the hydraulic motor 13 is started to rotate the core drill bit 14, core sampling of the road surface is achieved. The pile driving principle of the pile driver 15 here is the same as the above description and will not be elaborated further here;

[0035] Through the above description, the two lifting frames 7 are arranged in a symmetrical structure, enabling the transverse movement assembly 4 and the two lifting frames 7 to form an "H"-shaped gantry, making its stability better. At the same time, the core drill bit 14 and the pile driver 15 can each achieve the working strokes of swinging left and right and moving up and down, making them non-interfering with each other. At the same time, double operations of pile driving and core sampling can be achieved;

[0036] When the core drill bit 14 needs to perform core sampling operations, the staff can turn on the submersible pump in the water tank 18, and then pull out the nozzle on the water pipe 180 and aim it at the core sampling area of the core drill bit 14 to spray atomized water mist, enabling the core drill bit 14 to play a role in dust reduction and lubrication, that is, reducing the dust raising at the operation site and at the same time increasing the service life of the core drill bit 14.
