DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0029] like Figure 1-6 As shown, the embodiment of the present application discloses an anti-dumping device for geotechnical engineering survey and drilling, including a top plate 10, a bottom plate 20, a mounting seat 11, a support arm 30, and a support assembly 40. The top plate 10 and the bottom plate 20 are arranged at intervals in the upper and lower parts, and a plurality of support columns 21 are arranged between the top plate 10 and the bottom plate 20 for stably connecting the top plate 10 and the bottom plate 20. The mounting seat 11 is arranged in the middle of the top plate 10 for installing a drilling device. A through hole 22 is arranged in the middle of the top plate 10 and the bottom plate 20 for the drill bit of the drilling device to pass through and drill into the soil layer. Connecting columns 12 are vertically arranged at the corners of the top plate 10, and the support arm 30 is rotatably arranged on the connecting column 12. The support assembly 40 is arranged at the end of the support arm 30 away from the connecting column 12. The support assembly 40 and the support arm 30 provide supporting force for the top plate 10, ensuring the stability of the top plate 10, thereby ensuring the stability of the drilling device, and the rotation adjustment of the support arm 30 can avoid obstacles in the surrounding environment, and can also be used in complex environments, which is more convenient.

[0030] Specifically, the lower end of the connecting column 12 passes through the top plate 10 and extends downward and is fixedly connected to the bottom plate 20, so that the structural strength of the connecting column 12 is higher. An arc groove 13 centered on the connecting column 12 is provided on the top plate 10, and the arc radius of the arc groove 13 is less than half the width of the support arm 30, so that the support arm 30 blocks the arc groove 13 to prevent soil or debris from entering between the top plate 10 and the bottom plate 20 from the arc groove 13. A threaded rod 31 is rotatably provided on the support arm 30, and the lower end of the threaded rod 31 passes through the arc groove 13 and is spirally provided with a nut 32. A limiting mechanism 50 for limiting the rotation of the nut 32 is also provided at the lower part of the top plate 10. The threaded rod 31 is screwed to lock the nut 32, so that the threaded rod 31 and the nut 32 clamp the support arm 30 and the top plate 10, thereby fixing the support arm 30 and ensuring the stability of the support arm 30 supporting the top plate 10. The arc of the arc groove 13 is two-thirds of a circle, so that the rotation adjustment range of the support arm 30 is larger and more convenient.

[0031] When set, the limiting mechanism 50 includes an annular groove 51 provided at the bottom of the top plate 10, a slider 52 is slidably provided in the annular groove 51, and the slider 52 is connected to the nut 32. The nut 32 is limited by the annular groove 51 and the slider 52 to prevent the nut 32 from rotating when the threaded rod 31 rotates, thereby making it impossible for the nut 32 to be locked. The annular groove 51 is arranged concentrically with the arc groove 13, so that the support arm 30 and the threaded rod 31 rotate around the connecting column 12, and when the nut 32 rotates, the slider 52 slides in the arc groove and is always connected to the nut 32. A baffle 33 is provided at the lower end of the threaded rod 31 to limit the stroke of the nut 32 moving up and down, so as to prevent the threaded rod 31 from rotating too much when the threaded rod 31 is rotated to loosen the nut 32, causing the nut 32 to be separated from the threaded rod 31. When the nut 32 is locked, the distance from the top surface of the baffle 33 to the bottom surface of the nut 32 is smaller than the height of the slider 52, so that when the nut 32 is at the lowest position, the top of the slider 52 is still located in the annular groove 51, preventing the top of the slider 52 from escaping from the annular groove 51 so that the slider 52 cannot limit the rotation of the nut 32.

[0032] In the specific setting, the support assembly 40 includes a vertically arranged threaded column 41, the support arm 30 is screwed with the threaded column 41 through a threaded hole, the upper end of the threaded column 41 is provided with a rotating handle 42, and the lower end is provided with a supporting plate 43. Turning the rotating handle 42 drives the threaded column 41 to rotate, and the threaded column 41 moves upward or downward while rotating, driving the supporting plate 43 to move up and down, so that the height of the supporting plate 43 can be adjusted according to the height of the ground to obtain better supporting force. A nail column 44 is vertically arranged at the bottom of the supporting plate 43, and the nail column 44 is used to pierce the soil to further fix the position of the supporting plate 43.

[0033] A panel 23 is provided between the outer edge of the top plate 10 and the outer edge of the bottom plate 20, a round tube 14 is provided in the through hole 22 of the top plate 10, and the lower end of the round tube 14 is connected to the through hole 22 of the bottom plate 20 to prevent dirt or debris from entering between the top plate 10 and the bottom plate 20 and making cleaning inconvenient.

[0034] The use principle of an anti-dumping device for geotechnical engineering survey and drilling in the present embodiment is: first adjust the support arm 30 to a suitable position, then screw the threaded rod 31 to lock the nut 32, so that the threaded rod 31 and the nut 32 clamp the support arm 30 and the top plate 10, fix the support arm 30, and then turn the rotating handle 42 to drive the threaded column 41 to rotate. When the threaded column 41 rotates, it simultaneously descends and drives the support plate 43 to descend until it contacts the ground, so that the support arm 30 provides support force for the top plate 10, and the rotation adjustment of the support arm 30 can avoid obstacles in the surrounding environment. It can also be used in complex environments, which is more convenient.

[0035] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments.
