Description

Technical Field

[0001] This utility model relates to the field of directional drilling technology, and in particular to a feeding device for a directional drilling rig. Background Technology

[0002] Directional drilling rigs for coal mines are currently the main drilling equipment used in underground coal mines. They are high-torque directional drilling rigs suitable for large-diameter, near-horizontal, deep-hole composite directional drilling, capable of drilling 2000m long directional boreholes to meet the needs of high-level gas drainage drilling in coal seams and roofs. They are mainly used for drilling large-diameter gas drainage boreholes and other types of engineering boreholes in underground coal mines.

[0003] For example, the utility model application with application number CN202420723037.6 discloses a tracked directional drilling rig for coal mines, including a main unit and a tracked vehicle body. The main unit consists of a rotary head, a feeding device, a clamping device and an angle adjustment device. The tracked vehicle body is also equipped with an operating console and a pump station.

[0004] However, when in use, the aforementioned angle adjustment device relies on hydraulic cylinders to directly lift the main unit, lacking a lateral linkage mechanism. This can easily cause the rotary head to shift during lifting, increasing the drilling angle error. In addition, the frame stability is insufficient during feeding, which may cause the drill rod to shift. After a long period of operation, the guide rail needs to be replaced. Traditional guide rail replacement takes a long time, indicating room for improvement.

[0005] Therefore, this application proposes a feeding device for a directional drilling rig. Utility Model Content

[0006] The present invention aims to solve the technical problems existing in the prior art and provide a feeding device for a directional drilling rig.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] A feeding device for a directional drilling rig includes a frame, a mounting base on the left side of the frame, a column on the right side of the frame, an angle-adjusting cylinder for lifting at the bottom of the frame, a slide plate at the top of the frame, and a feeding cylinder for pushing the slide plate inside the frame cavity. There are two sets of sliding rods and columns. An auxiliary stabilizing assembly includes a second stabilizing frame positioned between the two sets of sliding rods and a first stabilizing frame positioned between the two sets of columns. A guide rail assembly is positioned between the frame and the slide plate, and includes a base plate and two sets of wear-resistant guide rails mounted together on the base plate.

[0009] According to the feeding device of the directional drilling rig, the bottom ends of the two sets of slide rods are movably mounted with mounting bases, and two sets of first clamps are fixedly mounted on the side of the frame near the slide rods, with the slide rods moving through the corresponding first clamps.

[0010] According to the feed device of the directional drilling rig, a crossbeam is fixedly installed between the two sets of first clamps, and a second clamp is fixedly installed on the outer wall of both sets of slide rods. The second stabilizing frame is U-shaped, and the two ends of the second stabilizing frame are fixedly connected to the two sets of second clamps respectively. The two sets of slide rods are in a parallel state to each other.

[0011] According to the feeding device of the directional drilling rig, a protrusion is fixedly connected to one end of the frame near the column, and a rotating shaft is fixedly installed between the two sets of columns. The rotating shaft moves through the protrusion at one end of the frame. The first stabilizing frame is U-shaped and is fixedly installed on the outer wall of the two sets of columns. The two sets of columns are parallel to each other.

[0012] According to the feeding device of the directional drilling rig, two sets of base plates are provided at the top of the frame, and the two sets of base plates are welded and fixed to both sides of the top of the frame.

[0013] According to the feeding device of the directional drilling rig, the top of the base plate has multiple sets of threaded mounting holes, and the wear-resistant guide rail has multiple sets of mounting holes. Bolts can be moved through the corresponding mounting holes and threaded mounting holes.

[0014] According to the feeding device of the directional drilling rig, rectangular grooves are provided on both sides of the bottom end of the slide plate. The slide plate and the wear-resistant guide rail are in a movable engagement relationship. Limiting plates are fixed to the bottom ends of the outer walls on both sides of the slide plate by bolts. The limiting plates are in contact with the bottom end of the wear-resistant guide rail. The cross-section of the wear-resistant guide rail and the bottom plate is "Z" shaped.

[0015] This utility model provides a feeding device for a directional drilling rig, which has the following advantages:

[0016] (1) By setting slide rods and columns on both sides of the frame, the angle adjustment cylinder, together with the slide rod and the first clamp, lifts one end of the frame to achieve the adjustment of the tilt angle, adapting to the directional drilling needs of complex formations downhole. By setting auxiliary stabilizing components, the first stabilizing frame and the second stabilizing frame improve the stability of the frame, making construction safer and more reliable, suppressing displacement caused by operational vibration. By setting the guide rail assembly and the feed cylinder to adopt a split design, it is convenient to quickly replace the wear-resistant guide rail.

[0017] (2) By installing mounting bases at the bottom of both sets of slide rods, and fixing the mounting bases and the bottom of the columns on the tracked vehicle body, two sets of first clamps are fixedly installed on the side of the frame near the slide rod. The slide rod moves through the corresponding first clamp. When the angle adjustment cylinder works, one end of the frame is lifted, the slide rod tilts, and the first clamp slides on the slide rod. The sliding fit structure between the slide rod and the first clamp forms a self-adjusting support mechanism, which suppresses vibration and displacement during the tilting or advancing of the drilling rig and prevents the drill rod from deviating. This is crucial for directional drilling in complex strata, ensuring the stability of the hole and the safety of the operation.

[0018] (3) Two sets of base plates are welded and fixed to the top of the frame on both sides, and multiple sets of threaded mounting holes are opened on the base plates. Multiple sets of mounting holes are opened on the wear-resistant guide rails. The two wear-resistant guide rails are installed on the top of one base plate, which makes it easy to replace the wear-resistant guide rails individually and makes maintenance simple and convenient. Rectangular grooves are opened on both sides of the bottom end of the slide plate. The slide plate and the wear-resistant guide rail are in a movable engagement relationship, which restricts the horizontal degree of freedom. The cross section of the wear-resistant guide rail and the base plate is "Z". The bottom end of the outer wall on both sides of the slide plate is fixed with a limit plate by bolts. The limit plate contacts the bottom end of the wear-resistant guide rail to form a vertical mechanical stop. The double limit suppresses the offset caused by the operation vibration and ensures the high precision and stability of the movement. Attached Figure Description
