DETAILED DESCRIPTION OF THE INVENTION DETAILED DESCRIPTION OF THE INVENTION

[0027] The following further describes the present utility model in detail in conjunction with embodiments:

[0028] Embodiment 1

[0029] As Figures 1-5 shown, the present utility model provides a bridge survey and drilling device for bridge engineering that is convenient for fixing, including a support base 1; a drilling unit 2 provided on the outer surface of the support base 1 for drilling; and a driving unit 3 provided on the top of the drilling unit 2 for traction. The drilling unit 2 includes a limiting component provided on the outer surface of the support base 1 and a drilling component provided inside the limiting component. The driving unit 3 includes a traction component provided on the outer surface of the drilling unit 2 and a clamping component provided on the outer surface of the traction component. The limiting component includes a limiting groove body 21. A fixing plate 23 is fixedly connected to the outer surface of the limiting groove body 21. A clamping groove 24 is fixedly connected to the upper surface of the fixing plate 23. A limiting rod 25 is detachably connected to the inner wall of the clamping groove 24. The drilling component includes a lifting plate 22. The outer surface of the lifting plate 22 is slidably connected to the inner wall of the limiting groove body 21. A driving motor 1 26 is detachably connected to the top of the lifting plate 22. The driving end of the driving motor 1 26 is rotatably connected to a limiting plate 27 that is detachably connected to the bottom surface of the lifting plate 22. The driving end of the driving motor 1 26 is detachably connected to a sampling drill bit 28. A discharge plate 281 is slidably connected to the inner wall of the sampling drill bit 28. When using the bridge survey and drilling device, first remove the limiting rod 25 from the inside of the clamping groove 24, and then start the driving unit 3 to drive the lifting plate 22 to lift and lower under the limitation of the limiting groove body 21. While the lifting plate 22 is descending, by starting the driving motor 1 26, the driving end of the driving motor 1 26 drives the sampling drill bit 28 to rotate under the limitation of the limiting plate 27, thereby sampling the soil. After the sampling is completed, insert the limiting rod 25 into the inside of the clamping groove 24, and then start the driving unit 3 to drive the sampling drill bit 28 to rise. When the discharge plate 281 contacts the limiting rod 25, due to the blocking effect of the limiting rod 25, the discharge plate 281 will push out the soil sample inside the sampling drill bit 28, thus facilitating the sampling of the sample.

[0030] Embodiment 2

[0031] As Figures 1-5As shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, the traction assembly includes a load-bearing plate 31. The bottom surface of the load-bearing plate 31 is fixedly connected to the top of the limit groove body 21. The upper surface of the load-bearing plate 31 is detachably connected to a second driving motor 32. The driving end of the second driving motor 32 is detachably connected to a winch 33 that is detachably connected to the upper surface of the load-bearing plate 31. A steel cable is wound around the outer surface of the winch 33. The bottom surface of the load-bearing plate 31 is fixedly connected to a socket plate 37 that is slidably connected to the outer surface of the steel cable. The clamping assembly includes a hydraulic cylinder 34. The outer surface of the hydraulic cylinder 34 is detachably connected to the outer surface of the winch 33. The telescopic end of the hydraulic cylinder 34 is detachably connected to a limit block 35. The outer surface of the limit block 35 is movably clamped to a limit gear 36 that is fixedly connected to the rotating shaft of the winch 33. When it is necessary to drive the drilling unit 2 to move in the vertical direction, by starting the second driving motor 32, the driving end of the second driving motor 32 drives the winch 33 to rotate, and then drives the steel cable on the outer surface of the winch 33 to pull the lifting plate 22 upward. If it is necessary to limit the height of the lifting plate 22, the hydraulic cylinder 34 can be started to drive the limit block 35 to descend, so as to clamp the outer surface of the limit gear 36, complete the limit of the winch 33, and prevent the lifting plate 22 from moving.

[0032] Next, specifically describe the working principle of the bridge survey and drilling device for bridge engineering that is easy to fix. As

[0033] Figures 1-5 shown, when using the bridge survey and drilling device, first move the limit rod 25 out of the inside of the clamping groove 24, and then start the driving unit 3 to drive the lifting plate 22 to lift and lower under the limit of the limit groove body 21. While the lifting plate 22 is descending, by starting the first driving motor 26, the driving end of the first driving motor 26 drives the sampling drill bit 28 to rotate under the limit of the limit plate 27, so as to sample the soil. After the sampling is completed, insert the limit rod 25 into the inside of the clamping groove 24, and then start the driving unit 3 to drive the sampling drill bit 28 to rise. When it is necessary to drive the drilling unit 2 to move in the vertical direction, by starting the second driving motor 32, the driving end of the second driving motor 32 drives the winch 33 to rotate, and then drives the steel cable on the outer surface of the winch 33 to pull the lifting plate 22 upward. If it is necessary to limit the height of the lifting plate 22, the hydraulic cylinder 34 can be started to drive the limit block 35 to descend, so as to clamp the outer surface of the limit gear 36, complete the limit of the winch 33, and prevent the lifting plate 22 from moving. When the discharge plate 281 contacts the limit rod 25, due to the blocking effect of the limit rod 25, the discharge plate 281 will push out the soil sample inside the sampling drill bit 28, thereby facilitating the sampling of the sample.

[0034] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made to it, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements that do not depart from the spirit of the present utility model are within the protection scope of the present utility model.
