Description

Technical Field

[0001] The utility model relates to the field of drilling devices, in particular to an accurate positioning directional drilling device which is easy to adjust. Background Art

[0002] In the process of geological exploration, the main special mechanical equipment that drives the drill to drill physical geological data, cores, ore cores, cuttings, liquid samples, gas samples, etc. from underground is called a drilling rig for short.

[0003] The drilling rig mainly includes a body, power components, hydraulic components, drill rods, drill bits, gears, and various shafts, rods, sleeves, friction plates, and brake band components. When in use, it mainly drives the drill rod and drill bit to descend, and the drill rod and drill bit can rotate and drill into the ground. However, most of the existing drill rods and drill bits are vertically directional and can only perform vertical lifting and drilling. It is impossible to adjust the angle of the drill rod and drill bit according to different terrains.

[0004] Therefore, it is necessary to invent a precise positioning directional drilling device that is easy to adjust. Utility Model Content

[0005] The purpose of the utility model is to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a precisely positioned directional drilling device that is easy to adjust, comprising a machine body and a lifting assembly, the lifting assembly is installed inside the machine body, a connecting seat is arranged outside the lifting assembly, a positioning assembly is installed on the front of the connecting seat, a drilling assembly is installed on the lower end of the positioning assembly, a connecting shaft and a protractor are installed on the lower end of the front of the machine body, the connecting shaft is located in the middle of the protractor, a directional sleeve is installed on the end of the connecting shaft away from the machine body, and the drilling assembly movably passes through the directional sleeve;

[0007] A fixing sleeve is fixedly installed on the outside of the connecting shaft, a fingerboard is fixedly installed on the lower end of the fixing sleeve, and the fingerboard is located on the surface of the protractor.

[0008] Based on the above features: the lifting assembly is used to drive the connecting seat, the positioning assembly and the drilling assembly to descend, and the drilling assembly can be started to rotate at the same time, so that the descending drilling assembly can drill into the ground. During this process, the drilling assembly will pass through the fixed sleeve guide to enable the drilling assembly to achieve vertical directional drilling. When the drilling angle needs to be changed, the positioning assembly can be driven to rotate left or right. At this time, the positioning assembly will drive the drilling assembly to rotate and tilt. During this process, the fixed sleeve will also rotate through the connecting shaft to keep consistent with the drilling assembly. At the same time, the connecting shaft will drive the finger plate to rotate and tilt through the fixed sleeve. During the movement of the finger plate, it can be aligned with the scale on the surface of the protractor, so as to conveniently and accurately measure the inclination angle of the drilling assembly in a timely manner. Finally, it is only necessary to drive the inclined drilling assembly downward, and the fixed sleeve will remain stationary. The drilling assembly will pass through the inside of the fixed sleeve, and then the drilling assembly can be rotated to drill into the ground.

[0009] Preferably, guide grooves are symmetrically provided on the inner walls on both sides of the body, an arc groove is provided on the lower end of the front side of the body, and one end of the connecting shaft away from the directional sleeve is slidably connected to the arc groove.

[0010] Based on the above features: the connecting seat is guided and limited by the guide groove, so that the connecting seat, positioning assembly and drilling assembly maintain vertical movement, and one end of the connecting shaft is slidably connected to the machine body through an arc groove, so that the connecting shaft can drive the directional sleeve to rotate with the positioning assembly.

[0011] Preferably, the lifting assembly includes a lifting screw and a driving motor arranged at the upper end of the lifting screw, the external thread of the lifting screw is connected with a movable nut, and the connecting seat is fixedly installed on the outside of the movable nut.

[0012] Based on the above characteristics: when the driving motor is started to make the lifting screw rod rotate forward, the movable nut can drive the connecting seat to move downward, and when the lifting screw rod is reversed, the movable nut can drive the connecting seat to move upward.

[0013] Preferably, guide connecting rods are symmetrically installed on both sides of the connecting seat, a base is installed at the lower end of the connecting seat, a rotating motor is installed inside the base, and a rotating shaft is connected to the output end of the rotating motor.

[0014] Based on the above features: when the rotary motor is started, the positioning assembly and the drilling assembly can be driven to rotate through the rotating shaft.

[0015] Preferably, the positioning assembly includes a portal frame and through slots symmetrically opened on both sides of the portal frame, rodless cylinders are symmetrically installed on both sides of the outer ends of the portal frame, a movable slider is installed on one side of the rodless cylinder, a positioning slider is installed on one end of the movable slider, and the positioning slider moves through the through slot.

[0016] Based on the above features: when the positioning assembly and the drilling assembly are driven to rotate, the rodless cylinder can drive the drilling assembly to move up and down by moving the slider and the positioning slider, so that the drilling assembly can be moved and adjusted to perform drilling operations when it is not tilted.

[0017] Preferably, the drilling assembly comprises a top seat and a drilling motor mounted on the upper end of the top seat, a drilling rod is mounted on the lower ends of the top seat and the drilling motor, and a drill bit is mounted on the lower end of the drilling rod.

[0018] Based on the above characteristics: when the drilling motor is started, the drilling rod and the drill bit can be driven to rotate.

[0019] Preferably, the inner wall of the directional sleeve is provided with an annular array of anti-drop holes, and balls are arranged inside the anti-drop holes.

[0020] Based on the above features: the drilling rod can be oriented by passing through the directional sleeve, and the outer wall of the drilling rod can contact the ball, so that the two form rolling friction, which not only avoids the displacement of the drilling rod and the drill bit during vertical drilling or inclined drilling, but also avoids damage caused by direct friction with the inner wall of the directional sleeve when the drilling rod moves downward and rotates.

[0021] The beneficial effects of the utility model are:

[0022] 1. It is convenient to accurately position and adjust the angle of the drilling assembly. When vertical drilling is required, the drilling rod and the directional sleeve are kept in a vertical state, and the finger plate will be located in the middle position of the protractor. When the angle of the drilling rod and the drill bit needs to be adjusted, the rotating motor can drive the positioning assembly and the drilling assembly to rotate through the rotating shaft. During this process, the fixed sleeve will also rotate through the connecting shaft to keep consistent with the drilling assembly. At the same time, the connecting shaft will drive the finger plate to rotate and tilt through the fixed sleeve. During the movement of the finger plate, it can be aligned with the scale on the surface of the protractor to accurately measure the inclination angle of the drilling assembly, so that the drilling assembly can be accurately positioned.

[0023] 2. The directional sleeve is a hollow cylindrical structure with openings at both ends. When the drilling rod moves downward, the drilling rod can pass through the directional sleeve for orientation. At the same time, the outer wall of the drilling rod can contact the ball, so that the two form rolling friction. This not only avoids the displacement of the drilling rod and the drill bit during vertical drilling or inclined drilling, but also avoids damage caused by direct friction with the inner wall of the directional sleeve when the drilling rod moves downward and rotates.
