[0002] Drilling refers to the operation of using tools to drill holes and take samples to determine the geological conditions of the strata. It is an important technical means in geological exploration work. A drill rig is used to drill downward from the ground surface to form a cylindrical hole in the strata to identify and divide the strata. Cores, ore samples, and soil samples can be obtained from different depths in the drill hole for analysis and research to measure the physical and mechanical properties and indexes of rocks and soil layers and provide the design requirements. Before the construction of architectural engineering, drilling detection is required to determine the geological conditions of the soil, and generally a rotary drilling device is used for drilling.

[0003] Some existing rotary drilling devices do not have a buffer protection function for the drill bit. When the drill bit drills into a relatively hard object, the drill bit will get stuck. Under the continuous power supply of the drill bit power device, the drill bit will be damaged.

[0004] Therefore, those skilled in the art have provided a drilling device for architectural engineering planning and design to solve the problems raised in the above background technique. Content of the Utility Model

When the drill rod 9 is stuck, the drill rod 9 drives the connector 8 to stop rotating, and the motor 6 drives the runner 7 to continue rotating, which can retract the push rod 11 from the slot 13 to the active chamber 10. When the push rod 11 is completely out of the slot 13, the runner 7 can continue to drive the push rod 11 to slide on the inner wall of the connector 8 and enter the next slot 13. By analogy, the push rod 11 can continuously move in and out of the slot 13, and the torque of the motor 6 is partially released during this period, which can protect the drill rod 9.

The limiting rods 17 are slidably connected with the limiting sleeves 16. When the hydraulic rod 4 drives the fixing plate 5 to move up and down, the limiting rods 17 and the limiting sleeves 16 can ensure the stable lifting of the fixing plate 5 and the stable up and down movement of the drill rod 9 driven by the motor 6.

[0029] On the basis of the above embodiments, more specifically, a plurality of support rods 18 are provided at the bottom of the support base 1. A support leg 19 is slidably connected to the support rods 18. A plurality of adjustment holes 20 are opened on the support leg 19, and a positioning hole 21 is opened on the support rod 18. A plug pin 22 is provided between the adjustment hole 20 and the positioning hole 21. A clamping block 23 is provided on the support rod 18, and a bent handle 24 is provided on the plug pin 22. The support rods 18 are respectively fixedly installed at the four corners of the bottom of the support base 1 and can support the support base 1. The support leg 19 is slidably connected inside the support rod 18. When the ground is uneven, the extended length of the support leg 19 is adjusted, and the levelness of the support base 1 can be adjusted, which can ensure the safety of the drilling operation. A plurality of adjustment holes 20 are equidistantly opened on the outer wall of the support leg 19, and the positioning hole 21 is opened on the outer wall of the support rod 18. The plug pin 22 is inserted through the positioning hole 21 into different adjustment holes 20 to facilitate fixing the extended length of the support leg 19. The clamping block 23 is fixedly installed on the outer wall of the support leg 19, and the bent handle 24 is integrally formed at one end of the plug pin 22. After the plug pin 22 is inserted into the positioning hole 21 and the adjustment hole 20, the bent handle 24 is stuck on the clamping block 23, which can prevent the plug pin 22 from falling out of the positioning hole 21 and the adjustment hole 20.

[0030] In use, first, according to the flatness of the ground at the drilling position, adjust the extended length of the support leg 19 so that the support base 1 is placed stably. Subsequently, insert the pin 22 into the positioning hole 21 and the corresponding adjustment hole 20, and clamp the bent handle 24 on the clamping block 23. Then, start the motor 6 and the hydraulic rod 4. As the hydraulic rod 4 moves, the fixed plate 5 drives the motor 6 to move downward.

At the same time, the fixed plate 5 drives the limit rod 17 to slide downward in the limit sleeve 16. Meanwhile, under the action of the motor 6, the rotating wheel 7 drives the ejector rod 11 to rotate. The ejector rod 11 drives the connector 8 to rotate through the card slot 13. At the same time, the connector 8 drives the drill pipe 9 to rotate. As the hydraulic rod 4 extends, the drill pipe 9 contacts the ground and gradually drills. When the drill pipe 9 gets stuck and stops rotating, the drill pipe 9 drives the connector 8 to stop rotating. The motor 6 continues to drive the rotating wheel 7 to rotate. The torque of the motor 6 causes the ejector rod 11 to retract from the card slot 13 into the movable cavity 10. When the ejector rod 11 completely disengages from the card slot 13, the rotating wheel 7 continues to drive the ejector rod 11 to slide on the inner wall of the connector 8 and makes the ejector rod 11 enter the next card slot 13, and so on. The ejector rod 11 continuously enters and exits the card slot 13, and part of the torque of the motor 6 is released during this period. After the drilling is completed, control the hydraulic rod 4 to drive the fixed plate 5 to rise. At the same time, the fixed plate 5 drives the motor 6 and the drill pipe 9 to rise. When the drill pipe 9 leaves the ground and rises to the specified height, turn off the motor 6 and the hydraulic rod 4.
