[0003] A Chinese patent with the authorization announcement number CN 209976456 U discloses a stable drilling device for building foundation construction, which solves the shortcomings of the prior art that sand and stones splash when drilling and the height of the machine is difficult to adjust. It includes an upper seat, a lower seat, an electric cylinder and a drill bit. The bottom of the upper seat is connected and fixed to the lower seat through a fixing column, and electric cylinders are welded on both sides of the bottom of the lower seat. Threaded rods are installed on both sides of the bottom of the upper seat through a rotating motor, and the outer wall of the threaded rod is threadedly connected to an adjustment seat, and a drill bit is installed on the bottom of the adjustment seat through a rotating motor. However, the above technical solution still has the following shortcomings in actual use: the performance is relatively single, the stability is poor, and it can usually only be used for drilling, which is time-consuming and labor-intensive, and the drilling efficiency is low, and dust suppression cannot be performed, and there are certain limitations in use. Summary of the invention

[0004] The purpose of the present invention is to provide a drilling device for building foundation construction with controllable drilling position to solve the problems raised in the above background technology. To achieve the above purpose, the present invention provides the following technical solutions:

[0005] A drilling device for building foundation construction with controllable drilling position, comprising a water tank fixedly arranged on a support base, wherein four corners of the lower surface of the support base are provided with moving wheels to facilitate moving the entire drilling device to a designated position;

[0006] A height adjustment component for adjusting the height of the lifting column in the vertical direction is arranged on the upper surface of one side of the support base; a swing beam is rotatably arranged on the top of the lifting column, a support cover is fixedly arranged at the bottom of one end of the swing beam, a rotating disk is sealed and rotatably arranged at the bottom open end of the support cover, and an atomizing nozzle is arranged on one side of the rotating disk, and the atomizing nozzle is used to spray out the clean water in the inner cavity of the support cover in atomized form;

[0007] A drill rod is coaxially and sealingly arranged on the rotating disk for rotation, and a second servo motor for driving the drill rod to rotate is installed on the swing beam;

[0008] A third servo motor for driving the rotating disk to rotate is provided on one side of the support cover. Therefore, the third servo motor connected to a power source and started can drive the rotating disk to rotate. The rotating rotating disk can make the mist sprayed by the atomizing nozzle evenly cover the drilling position, which can effectively suppress dust.

[0009] A supporting crossbar is fixedly installed on the upper part of the lifting column, and a swing mechanism for swinging the swinging crossbar is arranged at one end of the supporting crossbar; a water supply component is also arranged in the water tank;

[0010] The swing mechanism includes a lifting sleeve that rotates and passes through the end of the supporting cross bar, a turntable is coaxially fixed on the top of the lifting sleeve, a guide column is fixed on the upper surface of one side of the turntable, one end of the swing beam is slidably sleeved on the guide column through a strip through hole opened thereon, and anti-slip nuts are detachably installed on the guide columns on the upper and lower sides of the swing beam to prevent the guide columns from slipping out of the strip through holes.

[0011] As a further limitation of the technical solution of the embodiment of the present invention, the swing mechanism also includes a fourth servo motor for driving the turntable to rotate, and the fourth servo motor is fixedly arranged on the top plate of the water tank.

[0012] As a further limitation of the technical solution of the embodiment of the present invention, the output shaft of the fourth servo motor is driven and connected with a driving shaft, and the upper part of the driving shaft radially slides and extends into the lifting sleeve. Therefore, when the fourth servo motor is used to drive the driving shaft to rotate, the rotating driving shaft can drive the lifting sleeve to rotate, thereby achieving the effect of driving the turntable to rotate, and the lifting sleeve can move downward relative to the driving shaft, which facilitates the height adjustment component to adjust the height position of the drill rod without interference.

[0013] As a further limitation of the technical solution of the embodiment of the present invention, the water supply assembly includes a U-shaped rod rotatably arranged in the water tank, a push-pull sleeve is slidably sleeved on the U-shaped rod, a push-pull rod is fixedly installed on one side of the push-pull sleeve, and the water supply assembly also includes a first servo motor for driving the U-shaped rod to rotate, and the first servo motor is fixedly installed on the support base.

Therefore, when the first servo motor is used to drive the U-shaped rod to rotate, the rotating U-shaped rod can push the push-pull sleeve to reciprocate in the horizontal direction, and then under the linkage action of the push-pull rod, the piston is pushed to reciprocate in the liquid cylinder, thereby achieving the effect of continuously delivering the clean water in the water tank to the support cover, and the clean water entering the support cover is atomized and sprayed out through the atomizing nozzle, thereby achieving the effect of dust reduction.

[0015] As a further limitation of the technical solution of the embodiment of the present invention, the height adjustment component includes a fixed cylinder fixedly set on the support base, a height adjustment screw rod is rotatably arranged in the fixed cylinder, and the height adjustment component also includes a forward and reverse motor for driving the height adjustment screw rod to rotate, wherein the forward and reverse motor is fixedly mounted on the support base.

[0016] As a further limitation of the technical solution of the embodiment of the present invention, the lifting column is sleeved on the height adjustment screw rod by a threaded connection, so the height of the lifting column in the vertical direction can be adjusted by controlling the rotation direction of the height adjustment screw rod;

[0017] The top end of the fixed cylinder is connected to the supporting cross bar by a supporting spring sleeved on the lifting column. The provided supporting spring can prevent the swinging cross beam from falling suddenly during the lifting process and causing damage to the drill rod part, thereby effectively ensuring the service life of the drilling device.

[0018] Compared with the prior art, in the drilling device provided in the embodiment of the present invention, a fourth servo motor is used. Therefore, when the rotating lifting sleeve drives the turntable to rotate, the guide column performs a circular motion, thereby being able to push the swing beam to rotate a certain angle around the top end of the supporting crossbar, so as to achieve flexible adjustment of the drilling position; and by setting the moving wheel, the flexibility of the use of the drilling device is further improved;

[0019] When the first servo motor is used to drive the U-shaped rod to rotate, the rotating U-shaped rod can push the push-pull sleeve to reciprocate in the horizontal direction, and then under the linkage action of the push-pull rod, the piston is pushed to reciprocate in the cylinder, thereby achieving the effect of continuously sending the clean water in the water tank to the support cover, and the clean water entering the support cover is sprayed out through the atomizing nozzle to achieve the effect of dust reduction;

[0020] The third servo motor connected to the power supply and started can drive the rotating disk to rotate. The rotating rotating disk can make the mist water sprayed by the atomizing nozzle evenly cover the drilling position, which can effectively suppress dust. BRIEF DESCRIPTION OF THE DRAWINGS
