DETAILED DESCRIPTION

[0021] The following embodiments are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0022] Example

[0023] like Figure 1 As shown, the utility model of a highway bridge construction drilling platform includes a frame structure, which includes a bottom plate 1, a vertical plate 2 and a horizontal plate 3, wherein two vertical plates 2 are respectively connected to the bottom plate 1 and the horizontal plate 3. Screw holes 4 for fixing are provided around the inner surface of the bottom plate 1, and a through groove 5 is provided in the middle of the inner surface of the bottom plate 1.

[0024] like Figure 2 As shown, a cylinder 6 is installed on the horizontal plate 3, and an adjustment plate 7 is fixedly connected to the output end of the cylinder 6, which can drive the adjustment plate 7 to move in the vertical direction. Both ends of the adjustment plate 7 are respectively connected to a slide bar 9, and the outer side of the slide bar 9 is slidably connected to a longitudinal slide groove 10 opened on the inner side of the vertical plate 2.

[0025] like Figure 2 and Figure 3 As shown, an adjusting box 8 is fixedly connected below the adjusting plate 7. A screw 12 placed in the horizontal direction is installed inside the adjusting box 8, and a servo motor 11 is fixedly connected to the right side of the adjusting box 8. The output end of the servo motor 11 is connected to the screw 12, and can drive the screw 12 to rotate. A screw sleeve 13 is threadedly connected to the surface of the screw 12, and a slider 20 is fixedly connected above the screw sleeve 13, and a connecting rod 14 is fixedly connected below. The slider 20 can slide in the transverse slide groove 19 processed on the top of the adjusting box 8. The connecting rod 14 extends downward from the guide groove 21 processed at the bottom of the adjusting box 8 and is fixedly connected to the buffer box 15, and the buffer box 15 is used to install the drilling motor 17 and the drill bit 18.

[0026] In this embodiment, the output end of the servo motor 11 drives the screw 12 to rotate, the screw 12 uses the action of the thread to drive the screw sleeve 13 to move horizontally, the screw sleeve 13 drives the connecting rod 14 to move horizontally, and the connecting rod 14 drives the buffer box 15, the drilling motor 17 and the drill bit 18 to move horizontally, so that the drilling position of the drill bit 18 can be adjusted laterally without moving the whole, thereby improving the overall convenience; by setting the transverse slide groove 19, the slider 20 and the guide groove 21, the stability of the screw sleeve 13 during the horizontal movement can be effectively improved.

[0027] like Figure 2 and Figure 4 As shown, a plurality of damping shock absorbers 22 are fixedly connected to the top of the inner cavity of the buffer box 15, and a buffer spring 23 is sleeved on the surface of the damping shock absorber 22. The bottom of the damping shock absorber 22 is fixed on the movable plate 24. The two ends of the movable plate 24 are movably installed in the guide grooves 25 processed on both sides of the buffer box 15. The bottom of the movable plate 24 is fixedly connected to the support frame 16, and the inner side of the support frame 16 is fixedly connected to the drilling motor 17, and the output end of the drilling motor 17 is fixedly connected to the drill bit 18. The drill bit 18 can pass through the through groove 5. The drill bit 18 generates vibrations during the drilling process, causing the movable plate 24 to move upward along the inner cavity of the guide groove 25, and then causing the damping shock absorber 22 and the buffer spring 23 to deform and squeeze upward. Through the above-mentioned adjustment structure, the vibration generated by the drill bit 18 can be buffered, which can effectively reduce noise and increase the service life of the drill bit 18.

[0028] In this embodiment, when the output end of the cylinder 6 drives the adjustment plate 7 and the adjustment box 8 to move downward, the drilling depth of the drill bit 18 can be adjusted.

At the same time, since the drill bit 18 vibrates during the drilling process, the movable plate 24 moves upward along the inner cavity of the guide groove 25, and then the damping shock absorber 22 and the buffer spring 23 are deformed and squeezed upward, which can buffer the vibration generated by the drill bit 18, effectively reduce noise, and at the same time increase the service life of the drill bit 18.
