Description

Technical Field

[0001] This utility model relates to the field of underground mining engineering machinery, and in particular to a device for rock drilling in medium and deep hole drilling rigs. Background Technology

[0002] Medium and deep hole drilling rigs are specialized equipment used for geological exploration and mineral mining. They are driven by hydraulic or electric systems to drill cores, mineral cores, rock cuttings, and other samples for analyzing underground geological structures or mineral resource distribution.

[0003] In existing deep-hole drilling operations in underground mines, drill rod replacement mainly relies on manual operation. Due to the large length and weight of drill rods, and the narrow working space, each manual rod replacement requires stopping the machine, disassembling, transporting the new drill rod, and repositioning it. Workers must operate under the drill arm and are also vulnerable to injury from falling rock cuttings or impacts from the swinging drill rod. Furthermore, existing automatic rod changing devices mostly use robotic arm structures, which can only be used on large, vehicle-mounted medium-deep-hole drilling rigs. These devices are not only heavy but also cannot be deployed in narrow mine tunnels. Therefore, a device for medium-deep-hole drilling rigs is proposed to solve the above problems.

A mounting seat 4 for driving the drive component 7 is slidably connected to the inner wall of the drive frame 2. The drive component 7 is fixedly connected to the outer wall of the mounting seat 4. The drive component 7 is a drive device for drilling holes with the drill rod, which is existing technology. A drill rod replacement mechanism is mounted on the lower surface of the drive frame 2, enabling drill rod replacement without manual intervention. The drill rod replacement mechanism includes a drill rod placement assembly 5, which includes a mounting shell 51 for housing and protecting the drill rod. The mounting shell 51 is fixedly connected to the outer wall of the drive frame 2 and is controlled by the drive frame. 2. Support is provided. A motor 52 for driving the rotating rod 53 to rotate is installed on the outer wall of the mounting shell 51. The output shaft of the motor 52 is fixedly connected to the rotating rod 53 for driving the telescopic rod 54 to rotate. The outer wall of the rotating rod 53 is fixedly connected to the telescopic rod 54, which is two sleeved square long rods. The telescopic rod 54 is used to push the drill rod upward out of the mounting shell 51. The telescopic rod 54 is elastic and maintains an inward pulling force when it is retracted into the mounting shell 51. The top of the telescopic rod 54 is provided with a U-shaped groove. The limiting block 55 is set at the U-shaped groove of the telescopic rod 54. The U-shaped groove is used to squeeze and fix the drill rod. The inner wall of the telescopic rod 54 is slidably connected to the limiting block 55 for pressing the drill rod. The outer wall of the telescopic rod 54 is slidably connected to the pushing block 56 for driving the limiting block 55 to move. The outer wall of the telescopic rod 54 is fixedly connected to the moving rod 57 for pushing the pushing frame 63 upward to stretch the telescopic rod 54.

[0033] Reference Figure 3 , Figure 4 and Figure 5The drill pipe replacement mechanism also includes a drill pipe retraction assembly 6, used to remove the drill pipe from the telescopic rod 54. The drill pipe retraction assembly 6 includes an electric push rod 61 and an air pump 62. The electric push rod 61 is used to push the push frame 63 to move. Both the electric push rod 61 and the air pump 62 are mounted on the outer wall of the mounting housing 51 and supported and fixed by the mounting housing 51. The output shaft of the electric push rod 61 is fixedly connected to the push frame 63 for driving other components to move. The upper surface of the push frame 63 is fixedly connected to a push block 5 for driving the protective housing 65 to push. The airbag 64 of the 6 has a protective shell 65 fixedly connected to its outer wall for protection. The pusher 63 is U-shaped and can move both sides of the drill rod together. The pusher 63 is slidably connected to the inner wall of the mounting shell 51 and is supported and fixed by the mounting shell 51. The air pump 62 is fixedly connected to the airbag 64 through a connecting pipe. The air pump 62 controls the expansion and contraction of the airbag 64. The upper surface of the protective shell 65 is fixedly connected to a pull plate 8 for causing the airbag 64 to contract and drive the pusher block 56 to move downward.

[0034] Reference Figure 3 , Figure 5 and Figure 6 The rotating rod 53 is rotatably connected to the inner wall of the mounting shell 51, and is supported and restricted by the mounting shell 51. The pushing block 56 is slidably connected to the outer wall of the restricting block 55, and is used to push the restricting block 55 to move. Multiple sets of telescopic rods 54 are provided, and the multiple sets of telescopic rods 54 are arranged in a rotating array around the center line of the rotating rod 53 as the rotation axis, which can store multiple sets of drill rods. When in use, the drill rods can be sent out one by one. The restricting block 55 is trapezoidal in shape. When the pushing block 56 pushes, the vertical force is converted into a lateral compressive force. The outer wall of the restricting block 55 is fixed. A friction pad 9 is connected to ensure that the drill rod is secured when the limiting block 55 moves. The upper surface of the push block 56 is provided with an inclined surface, which can cooperate with the limiting block 55 to fix the drill rod when it moves upward. The shape of the push block 56 is set as L-shaped. When it moves between the pull plate 8 and the protective shell 65, the position of the push block 56 is controlled by the air bag 64. Multiple sets of limiting blocks 55 and push blocks 56 are provided. The multiple sets of limiting blocks 55 and push blocks 56 are symmetrically arranged with the center line of the telescopic rod 54 as the axis of symmetry, so that the limiting block 55 can squeeze and fix the drill rod from both sides to the middle.

[0035] Working principle: In use, the drive frame 2 first rotates around the inner wall of the rotating disk 1, causing the mounting base 4 and drive component 7 to deflect as a whole, positioning the drill rod at the required angle. Then, the drive component 7 is started, driving the drill rod to rotate and advance for rock drilling. When the current drill rod reaches its usage limit and a new drill rod is needed, the drive component 7 disengages from the current drill rod and retracts to its initial position. The motor 52 is started to drive the rotating rod 53 to rotate, causing the telescopic rod 54 corresponding to the target drill rod to rotate to the working position. Then, the air pump 62 is started, inflating the air bag 64 and pushing the push block 56 above the protective shell 65, causing the push block 56 to move along the telescopic rod 54. The drill rod slides up the wall, and the inclined surface of the push block 56 interacts with the trapezoidal inclined surface of the limiting block 55, forcing the symmetrically arranged limiting blocks 55 to slide towards the center of the telescopic rod 54. The friction pad 9 presses the drill rod to achieve temporary fixation. Then, the electric push rod 61 is activated. The electric push rod 61 drives the push frame 63 to extend the telescopic rod 54 upward. Then, the drive component 7 is inserted into the drill rod, and the airbag 64 extends and retracts. The limiting block 55 is released from compression and fixation, and the replacement of the drill rod is completed. To retract the drill rod, the above steps can be repeated in reverse. At the same time, the drill rod placement component 5 can pre-store various specifications of drill rods, which can be quickly called up as needed by rotating the rotating rod 53.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
