Description

Technical Field

[0001] This utility model relates to the field of engineering geological drilling technology, and in particular to a drilling straightening mechanism for green engineering geological drilling. Background Technology

[0002] A search revealed that application number 202323208083.7 discloses a drilling straightening mechanism for engineering geological drilling, including a base, multiple sets of legs fixedly installed on the side of the base, and an inner column fixedly installed at the top. Two sets of connecting plates are fixedly installed on the outer circumference of the inner column, multiple sets of ball bearings are embedded in the side of the connecting plates, and multiple sets of fixing holes are opened at the top of the side. An outer column is slidably installed on the outer circumference of the inner column, and multiple sets of through holes are opened on the side of the outer column. A handle is fixedly installed on the side, and a threaded rod is threaded through the side of the base.

[0003] The drilling straightening mechanism for engineering geological drilling described in this patent application extends the outer column by sliding it on the outer circumference of the inner column, facilitating height adjustment and making it suitable for straightening drilling devices of different heights. However, in this process, the device uses bolts to connect the through holes and fixing holes to achieve fixed installation between the outer and inner columns. The fixing holes are located on the connecting plate and are fixed in position, which limits the height adjustment of the device and reduces its adaptability. Therefore, we propose a drilling straightening mechanism for green drilling in engineering geology. Utility Model Content

[0004] The present invention aims to solve the technical problems existing in the prior art and provide a drilling straightening mechanism for green drilling in engineering geology.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a drilling straightening mechanism for green drilling in engineering geology, comprising an equipment base, an inner support column fixedly installed on the top of the equipment base, and an outer support column sleeved on the outside of the inner support column. A connecting plate is fixedly installed on the side of the inner support column, and fixing holes are arranged on the side of the outer support column. Through holes are arranged on the side of the connecting plate. An adjustment mechanism is provided at the top of the outer support column. The adjustment mechanism includes an adjusting outer column threadedly connected to the top of the inner support column and a telescopic outer column threadedly connected to the top of the outer wall of the adjusting outer column. A limiting mechanism is provided between the outer support column and the telescopic outer column. The limiting mechanism includes a limiting slider fixedly connected to the top of the outer wall of the outer support column and a connecting block fixedly connected to the bottom of the outer wall of the telescopic outer column. A limiting slide rod fixedly connected to the bottom end of the connecting block is slidably connected to the end of the limiting slider away from the outer support column.

[0006] Furthermore, the side of the connecting plate is equipped with ball bearings that roll in contact with the inner wall of the outer support column.

[0007] Furthermore, the outer circumferential wall of the adjusting column is provided with two adjusting external threads in opposite directions at its upper and lower ends.

[0008] Furthermore, the top of the inner cavity sidewall of the supporting outer column and the bottom of the inner cavity sidewall of the telescopic outer column are provided with two adjusting internal threads that are adapted to the two adjusting external threads.

[0009] Furthermore, the upper and lower ends of the adjusting outer column are respectively threaded to the top of the inner cavity of the supporting outer column and the bottom of the inner cavity of the telescopic outer column.

[0010] Furthermore, an adjusting ring is fitted at the middle position of the outer wall surface of the adjusting outer column.

[0011] Furthermore, a connecting rod is uniformly fixedly installed between one end of the inner side of the adjusting ring and the middle of the outer wall of the adjusting outer column.

[0012] Furthermore, two fastening bolts are threaded onto the outer wall surfaces of the two limiting sliders.

[0013] Furthermore, the ends of the two fastening bolts respectively press against the outer wall surfaces of the two limiting slide bars at corresponding positions.

[0014] This utility model provides a drilling straightening mechanism for green drilling in engineering geology. It has the following beneficial effects:

[0015] 1. This drilling straightening mechanism for green drilling in engineering geology, through the setting of an adjustment mechanism, allows for initial adjustment of the overall height of the equipment by first adjusting the outer support column to a suitable position along the outer side of the inner support column. Bolts are then inserted through the through holes and threaded into the fixing holes to secure the inner and outer support columns. Next, rotating the adjustment ring drives the outer adjustment column to rotate. Since the upper and lower ends of the outer adjustment column are threaded to the top of the inner cavity of the outer support column and the bottom of the inner cavity of the telescopic outer column, respectively, the outer support column and the telescopic outer column move closer to or further away from each other along the outer wall of the outer adjustment column. This allows for the telescopic adjustment of the outer support column, the telescopic outer column, and the outer adjustment column, achieving precise adjustment of the overall height of the equipment. The operation is simple and practical, the structure is reasonable and compact, enabling convenient and precise adjustment of the overall height of the equipment and improving its practicality.

[0016] 2. This drilling straightening mechanism for green drilling in engineering geology features a limiting mechanism. The limiting slide rod is slidably connected to the limiting slider, creating a limiting and guiding effect between the supporting outer column and the telescopic outer column. By tightening the fastening bolts and pressing them against the outer wall of the limiting slide rod, the position between the supporting outer column and the telescopic outer column is fixed, improving the overall structural stability of the equipment. Furthermore, the supporting outer column, the telescopic outer column, and the connecting block cooperate to form a handle structure on the outside of the equipment, facilitating the adjustment of the position of the supporting outer column and further enhancing the practicality of the equipment.

A connecting plate 13 is fixedly installed on the side of the inner support column 11. Fixing holes 14 are arranged on the side of the outer support column 12, and through holes 15 are arranged on the side of the connecting plate 13. An adjustment mechanism is provided at the top of the outer support column 12. The adjustment mechanism includes an adjusting outer column 18 threadedly connected to the top of the inner end of the outer support column 12 and a telescopic outer column 17 threadedly connected to the top of the outer wall of the adjusting outer column 18. A limit mechanism is provided between the outer support column 12 and the telescopic outer column 17. The limit mechanism includes a limit slider 24 fixedly connected to the top of the outer wall of the outer support column 12 and a connecting block 23 fixedly connected to the bottom of the outer wall of the telescopic outer column 17. The end of the limit slider 24 away from the outer support column 12 is slidably connected to the bottom end of the connecting block 23. The connecting plate 13 has a ball bearing 16 installed on the side of the connecting plate 13, which rolls in contact with the inner wall of the outer support column 12. The outer circumferential wall of the adjusting column 18 has two adjusting external threads 19 with opposite directions at its upper and lower ends. The top of the inner wall of the outer support column 12 and the bottom of the inner wall of the telescopic column 17 have two adjusting internal threads 20 that are adapted to the two adjusting external threads 19. The upper and lower ends of the adjusting column 18 are threadedly connected to the top of the inner cavity of the outer support column 12 and the bottom of the inner cavity of the telescopic column 17, respectively. An adjusting ring 21 is sleeved at the middle of the outer wall of the adjusting column 18.

Next, rotate the adjusting ring 21 to drive the adjusting outer column 18 to rotate. Since the upper and lower ends of the adjusting outer column 18 are respectively threaded to the top of the inner cavity of the outer support column 12 and the bottom of the inner cavity of the telescopic outer column 17, the outer support column 12 and the telescopic outer column 17 move closer to or further away from each other along the outer wall of the adjusting outer column 18, realizing the extension and retraction of the outer support column 12, the telescopic outer column 17, and the adjusting outer column 18. The adjustment allows for precise adjustment of the overall height of the equipment. The operation is simple and practical, and the structure is reasonable and compact, enabling convenient and precise adjustment of the overall height and improving the equipment's usability.
