[0002] Hole expansion is a crucial technical link in many fields such as oil drilling, geological exploration and construction. Hole expansion refers to a special technical means adopted during the drilling process to increase the diameter of the borehole and improve the drilling efficiency and quality. Through hole expansion, the size of the borehole can be effectively expanded, thereby providing more spacious space for subsequent exploration, mining or construction. It can help drillers obtain underground oil and gas resources more smoothly and improve mining efficiency. In geological exploration, hole expansion also helps geologists to more accurately analyze and judge the distribution of underground rocks and mineral deposits.

[0023] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. For those skilled in the art, the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is only intended to provide a better understanding of the present invention by illustrating examples of the present invention.

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention provides a technical solution for a hole-reaming screw drill device: comprising a mobile body 1, a drill frame 2 is installed on the mobile body 1, a lifting module 21 is arranged on the drill frame 2, a drill seat 22 is connected to the moving end of the lifting module 21, a drill driver 23 is installed on the top of the drill seat 22, specifically, the drill driver 23 adopts advanced variable frequency speed regulation technology, and can adjust the speed and torque of the drill according to different drilling requirements, a drill screw 24 is connected to the output end of the drill driver 23, and a drill head mechanism 3 is arranged at the tail end of the drill screw 24;

[0025] The drill bit mechanism 3 includes an assembly square column 34 installed at the bottom of the drill screw 24, a guide cylinder 33 is installed at the bottom of the assembly square column 34, an extension seat 32 is installed at the bottom of the guide cylinder 33, a drill bit end 31 is installed on the extension seat 32, multiple groups of drill arms 35 are arranged around the extension seat 32, and are movably connected to the drill arms 35 through a pin shaft 39, a drill arm sleeve 351 is arranged at the rear end of the drill arm 35, and a support arm 36 is movably connected to the drill arm sleeve 351 through a pin shaft 39, the assembly square column 34 is outer-shaped with a square column guide sleeve 37, and a support seat 38 is arranged around the square column guide sleeve 37, a support arm 38 is arranged at the rear end of the support arm 36, and the support seat 38 and the support arm sleeve 361 are movably connected through a pin shaft 39.

[0026] In the above embodiment, the drill mechanism 3 can be flexibly extended and retracted to meet the drilling requirements of holes with different diameters. The drill driver 23 can provide sufficient power to drive the drill screw 24 to rotate, thereby driving the drill end 31 to perform drilling operations. The lifting module 21 can realize the up and down movement of the drill seat 22 to adjust the drilling position.

[0027] Furthermore, a sleeve 41 is mounted on the outer surface of the guide cylinder 33, and the sleeve 41 is connected to the extension seat 32 through two groups of hydraulic cylinders 43 symmetrically distributed. A secondary support arm 42 is arranged between the sleeve 41 and the drill arm 35, and both ends of the secondary support arm 42 are movably connected to it through a pin shaft 39.

[0028] In the above embodiment, when in use, the hydraulic cylinder 43 can control the extension and retraction of the sliding sleeve 41, thereby adjusting the distance between the square column guide sleeve 37 and the extension seat 32, so as to achieve precise adjustment of the drill mechanism 3. The deployment range of the drill arm 35 is controlled, and the setting of the secondary support arm 42 further enhances the stability of the drill arm 35, ensuring the stability and accuracy of the drill end 31 during the drilling operation.

[0029] Furthermore, a limit seat 40 is provided on the assembly square column 34 , and the limit seat 40 cooperates with the square column guide sleeve 37 .

[0030] In the above embodiment, the limiting seat 40 can limit the square column guide sleeve 37 to ensure the stability of the drill mechanism 3 during use.

[0031] Furthermore, a plurality of recesses 44 are disposed on the surface of each drill arm 35 , and a saw gear 45 is rotatably connected in each recess 44 .

[0032] In the above embodiment, efficient drilling can be achieved through the rotation of the saw gear 45, so that the drill bit end 31 can more accurately adapt to the hole expansion requirements under different geological conditions during the drilling process.

[0033] Furthermore, multiple sets of driving wheels 11 are arranged on both sides of the mobile body 1, a fixed frame 12 is installed on the mobile body 1, and the fixed frame 12 is movably connected to the drilling tool frame 2 through a pin shaft 39, an opening and closing hydraulic cylinder 13 is installed on the mobile body 1, the output end of the opening and closing hydraulic cylinder 13 is movably connected to the drilling tool frame 2 through a pin shaft 39, and the tail end of the opening and closing hydraulic cylinder 13 is movably connected to the mobile body 1 through a pin shaft 39.

[0034] In the above embodiment, the driving wheels 11 on both sides of the mobile body 1 can ensure the mobility of the device under different terrains, and the fixed frame 12 is movably connected to the drilling tool frame 2 through a pin shaft, so that the entire device remains stable during movement. The opening and closing hydraulic cylinder 13 allows the drilling tool frame 2 to be easily opened and closed, which is convenient for transportation and storage.

[0035] Furthermore, a control device 14 is installed on the mobile body 1 , a visual camera 26 is installed on the drill seat 22 , the control device 14 is connected to the visual camera 26 , and is control-connected to the drill driver 23 , the hydraulic cylinder 43 , and the opening and closing hydraulic cylinder 13 .

[0036] During the drilling operation, the visual camera 26 on the drill bit seat 22 can monitor the drilling situation in real time. By receiving the signal from the visual camera 26 through the control device 14, the operator can timely understand the drilling progress and geological conditions, and then adjust the speed and torque of the drill bit driver 23, as well as the moving speed and position of the lifting module 21 to ensure the smooth progress of the drilling operation.

[0037] Furthermore, a guide frame 25 is provided at the bottom of the drilling tool seat 22 , and the guide frame 25 is sleeved outside the drilling tool screw 24 .

[0038] In the above embodiment, the guide frame 25 is used to ensure that the drill screw 24 maintains the correct direction during the drilling process to prevent the drilling from deviating from the predetermined trajectory. The cooperation between the guide frame 25 and the drill screw 24 can reduce vibration during the drilling process and improve drilling accuracy.

[0039] The working principle of the present invention is as follows: when in use, the operator starts the driving wheel 11 of the mobile body 1 through the control device 14 to move the device to the predetermined drilling position. Then, the operator uses the control device 14 to start the opening and closing hydraulic cylinder 13 to expand the drilling tool frame 2 to the working state. Then, the operator starts the drilling tool driver 23, and the variable frequency speed regulation technology makes the drilling tool screw 24 rotate at an appropriate speed and torque, thereby driving the drill head 31 to start the drilling operation.

[0040] During the drilling process, the hydraulic cylinder 43 is started to control the extension and retraction of the sliding sleeve 41, adjust the distance between the square column guide sleeve 37 and the extension seat 32, and then control the expansion of the drill arm 35, the support arm 36 and the secondary support arm 42. The extension and retraction function of the drill mechanism 3 enables it to adapt to the needs of different apertures. Through the visual camera 26 to monitor the drilling situation in real time, the operator can adjust the parameters of the drill driver 23 in time to ensure the smooth progress of the drilling operation. At the same time, the up and down movement function of the lifting module 21 enables the drill seat 22 to adjust the drilling position to meet the drilling needs of different depths.

[0041] When the drilling reaches the predetermined depth, the operator stops the operation of the drilling tool driving machine 23 through the control device 14, and the operator activates the opening and closing hydraulic cylinder 13 through the control device 14 to retract the drilling tool frame 2 to the transportation state. The driving wheel 11 of the mobile body 1 is started again to move the device to the next drilling position or return to the base for maintenance and repair.

[0042] The hole-expanding screw drill device of the present invention can efficiently and accurately complete the drilling operation and is suitable for drilling needs under various geological conditions.
