Description

Technical Field

[0001] The utility model relates to the technical field of drilling equipment, in particular to a high-efficiency drilling device used in mining. Background Art

[0002] A mine refers to an independent production and operation unit that mines ores with a certain mining area. A mine mainly includes one or more mining workshops (also called pits, mines, open pits, etc.) and some auxiliary workshops. Most mines also include ore dressing plants.

[0003] In the process of mining, a drilling device is usually used to drill a hole in the geological layer. When the existing mining drilling machine is drilling, when the drill rod encounters greater resistance, the drill rod is prone to vibration, and the inner diameter of the hole increases with the vibration. At this time, if the drilling continues, the drill rod is prone to shaking in the hole. At this time, the horizontal shaking of the drill rod weakens the drilling effect of the drill rod, so that the drilling force cannot be fully applied in the drilling direction, thereby affecting the drilling efficiency.

[0026] See also Figure 1-5 The utility model provides an efficient drilling device for mining, comprising a lifting frame 1, a chain 2 is arranged inside the lifting frame 1, and a fixing frame 3 is fixedly connected to the outer wall of the chain 2.

[0027] Among them, a conveying motor 101 is fixedly connected to one side of the outer wall of the lifting frame 1, and the driving shaft of the conveying motor 101 passes through the lifting frame 1 and is fixedly connected to the first sprocket 102. The top bearing inside the lifting frame 1 is connected to the second sprocket 103. The outer walls of the first sprocket 102 and the second sprocket 103 are both meshed and connected with the chain 2. The first sprocket 102 is driven to rotate by the conveying motor 101, and the movement of the chain 2 is used to drive the fixed frame 3 and the drill rod mechanism to rise and fall for drilling.

[0028] A driving motor 4 is fixedly connected to the top of the fixing frame 3 . The driving shaft of the driving motor 4 passes through the fixing frame 3 and is provided with a drill rod assembly 5 . A limiting mechanism 6 is provided outside the drill rod assembly 5 .

[0029] The limiting mechanism 6 includes a base 7, anchor rods 10 are arranged on both sides of the base 7, and positioning holes 11 are opened at both ends of the base 7. The anchor rods 10 pass through the positioning holes 11 and extend underground. The base 7 is easily positioned through the anchor rods 10, so that the drill rod assembly 5 is limited by the base 7 when drilling, thereby improving the stability of the drilling angle and position, and making it less likely to deviate during drilling.

[0030] An annular groove 16 is provided at the center of the base 7 , and adjusting rods 8 are provided at both ends of the top of the base 7 , and a positioning plate 9 is provided on the top of the two adjusting rods 8 .

[0031] Among them, the adjusting rod 8 includes a sleeve 801 fixedly connected to the top of the base 7, and a movable rod 802 fixedly connected to the positioning plate 9 is slidably connected inside the sleeve 801. A latch 803 is provided on the outer wall of the sleeve 801. The latch 803 passes through the sleeve 801 and is plugged into the movable rod 802. A pin hole 804 corresponding to the latch 803 is provided on the outer wall of the sleeve 801. The movable rod 802 can be raised and lowered and slid in the sleeve 801 and fixed by the latch 803 to limit the height of the positioning plate 9.

[0032] An electric push rod 12 is fixedly connected to the side of the positioning plate 9 away from the lifting frame 1. The driving end of the electric push rod 12 passes through the positioning plate 9 and is fixedly connected to a limiting frame 13. A sliding groove 14 is opened inside the positioning plate 9. The limiting frame 13 is slidably connected to the sliding groove 14. Through the movable limiting frame 13, the two fan-shaped grooves 15 can be enclosed to limit the drill rod.

[0033] A fan-shaped groove 15 is provided on the opposite side of the positioning plate 9 and the limiting frame 13, and balls 17 are embedded in the inner walls of the fan-shaped groove 15 and the annular groove 16. There are a plurality of balls 17, which are evenly distributed on the inner walls of the fan-shaped groove 15 and the annular groove 16, so as to facilitate the limiting support of the drill rod in the groove from multiple angles.

[0034] In this embodiment, a slider 18 is slidably connected to the inner walls of the fan-shaped groove 15 and the annular groove 16. A ball groove corresponding to the ball 17 is opened inside the slider 18. A spring 19 is fixedly connected to the side of the slider 18 away from the ball 17. When the drill rod collides with the ball 17, the ball 17 can roll in the ball groove to reduce the friction on the drill rod. At the same time, the elasticity of the spring 19 is used to buffer the impact force.

[0035] During installation, the lifting frame 1 is attached to and fixedly connected to the mechanical arm of the external excavator, and can be moved along with the operation of the mechanical arm. When drilling, the mechanical arm can drive the lifting frame 1 to form a hole. Figure 5 The states shown and the specific operation procedures of the excavator and its attached mechanical arm are all prior art and will not be described in detail here.

[0036] When in use, the conveying motor 101, the driving motor 4 and the electric push rod 12 in the device are connected to an external power supply, and the conveying motor 101 drives the first sprocket 102 to rotate, drives the chain 2 to move, drives the fixed frame 3 and the drill rod assembly 5 to descend, and starts the driving motor 4 to drive the drill rod to rotate, and shallowly drill into the mine.

[0037] After that, the drill rod assembly 5 is lifted up, and based on the position of the hole, the limiting mechanism 6 is fixed on its top. After the anchor rod 10 penetrates the positioning hole 11, the base 7 is fixed on the top of the drill hole. Then, the drill rod assembly 5 is lowered and drilled into the hole again. The electric push rod 12 is started to drive the limiting frame 13 to be retracted, so that the two fan-shaped grooves 15 are surrounded and positioned together outside the drill rod.

[0038] At this time, the ball 17 fits smoothly with the outer wall of the drill rod. When the drill rod is lowered to drill a hole, the annular groove 16 and the two combined fan-shaped grooves 15 facilitate forming two-point positioning outside the drill rod, and limit the outside of the drill rod so that the drill rod can drill vertically, which greatly reduces the vibration generated when the drill rod encounters resistance during drilling, improves the stability of the drill rod when drilling, and makes the drilling force act in the drilling direction as much as possible, making the drilling more efficient.

[0039] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
