[0023] Refer to Figures 1-4, an embodiment provided by the present utility model: a novel bridge exploration drilling device, including a base 1. A hydraulic cylinder 2 is fixedly arranged on the top of the base 1. There are two groups of hydraulic cylinders 2 symmetrically arranged left and right. The output end of the hydraulic cylinder 2 is connected to a hydraulic push rod 3. A buffer member 4 is arranged at the top of the hydraulic push rod 3. The buffer member 4 can reduce the vibration generated during drilling. A moving plate 5 is installed on the top of the buffer member 4. Slide rods 10 are penetrated through both ends of the moving plate 5. The upper ends of the slide rods 10 are installed on a fixed frame 7, and the lower ends of the slide rods 10 are connected to the base 1. The moving plate 5 moves along the slide rods 10, making the movement of the moving plate 5 more stable. A drilling assembly 6 is arranged in the middle of the moving plate 5. A fixed frame 7 is arranged above the base 1. An adjusting assembly 8 is connected to the upper side of the moving plate 5. The depth of drilling can be controlled through the adjusting assembly 8 to achieve efficient drilling work;

[0024] The adjusting assembly 8 includes a connection box 81 slidably arranged inside the fixed frame 7. There are two groups of connection boxes 81 symmetrically arranged left and right. A driving gear 82 is arranged inside the connection box 81. A rotating rod 83 is penetrated through the inside of the driving gear 82. Both ends of the rotating rod 83 are rotatably arranged on the connection box 81, and one end thereof penetrates through the connection box 81 and extends outside the connection box 81. A crank 84 is arranged at the outer end of the rotating rod 83. A gear rack 85 is arranged on one side of the driving gear 82. The driving gear 82 meshes with the gear rack 85 on one side. The gear rack 85 slides inside the connection box 81. A scale line is arranged on the gear rack 85 for adjusting the drilling depth. An opening 86 is opened at the top of the connection box 81. The upper end of the gear rack 85 passes through the opening 86 and extends above the connection box 81. A limiting plate 87 is arranged at the upper end of the gear rack 85. A positioning rod 88 is installed on the fixed frame 7 below the limiting plate 87. By rotating the crank 84 to control the rotating rod 83 to drive the driving gear 82 to rotate, the gear rack 85 moves up and down to adjust the height of the limiting plate 87. When drilling, the hydraulic cylinder 2 controls the hydraulic push rod 3 to pull the moving plate 5 downward to drill, and at the same time the moving plate 5 pulls the connection box 81 to slide down until the limiting plate 87 abuts against the positioning rod 88. At this time, the depth of the drilled hole meets the adjusted depth, making the drilling work more efficient.

[0025] Activity grooves 11 are symmetrically opened at the bottom of the base 1 left and right. Electric telescopic rods 12 are arranged inside the activity grooves 11. The lower ends of the electric telescopic rods 12 are connected to universal wheels 13. The universal wheels 13 are movably arranged inside the activity grooves 11. When it is necessary to move the drilling device, the electric telescopic rods 12 push the universal wheels 13 to extend out of the activity grooves 11, and the device can be conveniently moved to a suitable position through the universal wheels 13.

[0026] The buffer member 4 includes a mounting block 41 fixedly arranged at the top end of the hydraulic push rod 3. A shock-absorbing spring 42 is arranged on the top of the mounting block 41. The upper end of the shock-absorbing spring 42 is connected with a rubber pad 43. The rubber pad 43 is fixedly connected with the moving plate 5. When drilling, the vibration generated by the drill bit 63 contacting the ground is transmitted to the shock-absorbing spring 42 through the moving plate 5. The shock-absorbing spring 42 is compressed by the force to dissipate the vibration, avoiding damage to the hydraulic push rod 3 caused by the vibration.

[0027] The drilling assembly 6 includes a motor 61 installed on the upper side of the moving plate 5. The output end of the motor 61 is connected with a rotating shaft 62. The rotating shaft 62 passes through the moving plate 5 through a bearing. A drill bit 63 is arranged at the lower end of the rotating shaft 62. A through groove 14 is arranged through the middle of the base 1. The drill bit 63 passes through the through groove 14 and contacts the ground. The motor 61 controls the rotating shaft 62 to drive the drill bit 63 to rotate for drilling.

[0028] On the inner walls of the connecting boxes 81 on both sides of the gear rack 85, sliding grooves 9 are formed. Inside the sliding grooves 9, sliding blocks 91 are movably arranged. The sliding blocks 91 are connected to the gear rack 85. When the gear rack 85 moves, the sliding blocks 91 move along the sliding grooves 9 to limit the gear rack 85 and ensure the smoothness of its operation.

[0029] Working principle: First, move the drill bit 63 to a suitable position through the universal wheels 13. The electric telescopic rod 12 drives the universal wheels 13 to retract into the movable groove 11 to keep the drill bit 63 stable. By rotating the hand crank 84, control the rotating rod 83 to drive the driving gear 82 to rotate, drive the gear rack 85 to move up and down, and adjust the height of the limiting plate 87. When drilling, the motor 61 controls the rotating shaft 62 to drive the drill bit 63 to rotate, and the hydraulic cylinder 2 controls the hydraulic push rod 3 to pull the moving plate 5 to move downward for drilling. At the same time, the moving plate 5 pulls the connecting box 81 to slide down until the limiting plate 87 abuts against the positioning rod 88. At this time, the depth of the drilled hole meets the adjusted depth, making the drilling work more efficient.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
