Description

Technical Field

[0001] This utility model relates to the field of rock drill rod positioning technology, and in particular to a rock drill rod positioning device. Background Technology

[0002] Currently, the rock drills typically used by on-site construction workers only have rear supports. The excessively long drill rods require support from the workers, and the intense vibrations from prolonged drilling directly impact their bodies, causing fatigue, exhaustion, and harm to their health. If workers leave immediately after aligning the drill rod with the blast hole marking point, the vibrations during drilling can easily cause the drill rod to swing, resulting in drilling errors and increasing the difficulty of operating the rock drill.

[0003] Most existing technologies use positioning devices to position the drill rod, thereby reducing the fatigue of personnel. However, these devices require multiple bolts to lock their position, which means that when the rock drill is drilling holes in multiple directions, the personnel need to constantly change the position of the positioning device, resulting in a long positioning time and a significant reduction in work efficiency. Utility Model Content

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a rock drill rod positioning device, including a fixed base, a first turntable rotatably mounted on the top of the fixed base, an installation box fixedly mounted on the top of the first turntable, a movable frame slidably mounted on the inner side of the installation box, and a drill rod positioning component provided on the movable frame;

[0005] The drill pipe positioning assembly includes a fixed cylinder, a sliding cylinder, a first threaded hole, a fixing bolt, and a mounting base. The fixed cylinder is fixedly installed on the top of the movable frame, and the sliding cylinder is slidably installed on the inner side of the fixed cylinder. The first threaded hole is formed on the fixed cylinder and the sliding cylinder. The fixing bolt is threaded on the inner side of the first threaded hole, and the mounting base is fixedly installed on the top of the sliding cylinder.

[0006] Preferably, a fixing plate is fixedly installed on the top of the fixing base, and a drill rod adjustment assembly is provided on the fixing base, the first turntable and the fixing plate.

[0007] Preferably, the drill pipe positioning assembly further includes a rotating shaft, a second turntable, a positioning pin, a first spring, and positioning holes. The rotating shaft is rotatably mounted on the top of the mounting base, the second turntable is fixedly mounted on the top of the rotating shaft, the positioning pin is slidably mounted on the top of the second turntable, one end of the first spring is fixedly mounted on the top inner wall of the positioning pin, and the other end of the first spring is fixedly mounted on the top of the second turntable. A plurality of positioning holes are formed on the top of the mounting base, and the positioning pin fits into the positioning holes.

[0008] Preferably, the drill pipe positioning assembly further includes a fixing box, an insertion block, a second threaded hole, a locking bolt, and a positioning bearing. The fixing box is fixedly installed on the top of the second turntable, the insertion block is disposed inside the fixing box, the second threaded hole is opened on one side of the insertion block and the fixing box, the locking bolt is threadedly installed inside the second threaded hole, and the positioning bearing is fixedly installed on the top of the insertion block.

[0009] By adopting the above technical solution, the length of the drill rod can be controlled by personnel during the rotation process when drilling. Therefore, the positioning bearing can only be positioned in one position and can help reduce the rotational friction. The drill rod is existing technology, so it is not described in detail in this article.

[0010] Preferably, the drill pipe adjusting assembly includes an insertion block comprising a ratchet, a pawl, a slide bar, a second spring, and a pull handle. The ratchet is fixedly mounted on the outer side of the first turntable, the plurality of slide bars are slidably mounted on the inner side of the fixed plate, the pawl is fixedly mounted on one side of the slide bar, one end of the second spring is fixedly mounted on one side of the pawl, the other end of the second spring is fixedly mounted on one side of the fixed plate, and the pull handle is fixedly mounted on the other side of the slide bar.

[0011] Preferably, the drill pipe adjusting assembly further includes a lead screw and a knob, the lead screw is rotatably mounted inside the mounting box, the knob is fixedly mounted on the outside of one end of the lead screw, and the movable frame is threadedly mounted on the inside of the lead screw.

[0012] Preferably, the top of the fixed cylinder has a through hole, and the sliding cylinder fits into the through hole.

[0013] By adopting the above technical solution, the through hole facilitates the sliding cylinder to slide above the fixed cylinder, thereby allowing the height of the positioning bearing to be adjusted.

[0014] Preferably, a limiting groove is provided on one side of the mounting box, and the movable frame is slidably installed inside the limiting groove. The movable frame is L-shaped.

[0015] By adopting the above technical solution, the limiting slide groove facilitates the guidance of the moving frame and makes the moving frame slide more stably. During the sliding process of the moving frame, the lead screw can be kept in a sealed state to prevent the waste chips generated during the drilling process from entering the surface of the lead screw.

[0016] Preferably, the top of the fixed box is provided with an insertion slot, and the insertion block fits into the insertion slot.

[0017] By adopting the above technical solution, the insertion slot can assist in the positioning and installation of the insertion block, making it easier and faster to insert the insertion block into the top of the fixed box.

[0018] Preferably, a sliding hole is provided on one side of the fixing plate, and the sliding rod is slidably installed inside the sliding hole.

[0019] By adopting the above technical solution, the sliding hole facilitates the limiting of the sliding rod, allowing the sliding rod to slide only in a designated position, and also allows the sliding rod to provide auxiliary support for the pawl.

[0020] The beneficial effects of this utility model are:

[0021] 1. This utility model, through the drill rod positioning component, allows the sliding cylinder to slide inside the fixed cylinder, adjusts the height of the positioning bearing, and fixes the position of the sliding cylinder by screwing the fixing bolt into the first threaded hole. The positioning bearing is inserted into the fixed box through the insertion block, and the locking bolt can be controlled to enter the second threaded hole to lock the insertion block. The second turntable in front of the drill rod can be controlled to rotate around the rotating axis. After rotating to a specified angle, the first spring can drive the positioning pin to slide into the positioning hole above the mounting base, so that the positioning bearing will not rotate during the auxiliary positioning process. This makes the device have a large adjustment angle, high stability, and is easy to operate.

[0022] 2. This utility model uses a drill rod adjustment assembly to install the fixed base in a designated position using bolts. When drill rod processing is required, pulling the handle moves the sliding rod and pawl, allowing the pawl to disengage from the ratchet. This controls the rotation of the mounting box above the first turntable, adjusting the positioning angle of the device. After adjustment, releasing the handle allows the second spring to move the pawl, thus locking the pawl against the ratchet. The sliding rods on both sides provide lateral support to the pawl, preventing it from loosening or shifting during locking, resulting in a better locking effect. The control knob rotates the lead screw, which, through threaded engagement, moves the movable frame. Attached Figure Description

[0031] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a rock drill rod positioning device, including a fixed base 3, a first turntable 4 rotatably mounted on the top of the fixed base 3, an installation box 5 fixedly mounted on the top of the first turntable 4, a movable frame 6 slidably mounted on the inner side of the installation box 5, and a drill rod positioning component 1 provided on the movable frame 6.

[0032] The drill pipe positioning assembly 1 includes a fixed cylinder 11, a sliding cylinder 12, a first threaded hole 13, a fixing bolt 14, and a mounting base 15. The fixed cylinder 11 is fixedly installed on the top of the movable frame 6, the sliding cylinder 12 is slidably installed on the inner side of the fixed cylinder 11, the first threaded hole 13 is formed on the fixed cylinder 11 and the sliding cylinder 12, the fixing bolt 14 is threaded on the inner side of the first threaded hole 13, and the mounting base 15 is fixedly installed on the top of the sliding cylinder 12.

[0033] In this embodiment, a fixing plate 32 is fixedly installed on the top of the fixing base 3, and a drill rod adjustment assembly 2 is provided on the fixing base 3, the first turntable 4 and the fixing plate 32.

[0034] In this embodiment, the drill pipe positioning assembly 1 further includes a rotating shaft 16, a second turntable 17, a positioning pin 18, a first spring 19, and positioning holes 25. The rotating shaft 16 is rotatably mounted on the top of the mounting base 15, the second turntable 17 is fixedly mounted on the top of the rotating shaft 16, the positioning pin 18 is slidably mounted on the top of the second turntable 17, one end of the first spring 19 is fixedly mounted on the top inner wall of the positioning pin 18, and the other end of the first spring 19 is fixedly mounted on the top of the second turntable 17. Multiple positioning holes 25 are formed on the top of the mounting base 15, and the positioning pin 18 fits into the positioning holes 25.

[0035] In this embodiment, the drill pipe positioning assembly 1 further includes a fixing box 20, an insertion block 21, a second threaded hole 22, a locking bolt 23, and a positioning bearing 24. The fixing box 20 is fixedly installed on the top of the second turntable 17. The insertion block 21 is disposed inside the fixing box 20. The second threaded hole 22 is opened on one side of the insertion block 21 and the fixing box 20. The locking bolt 23 is threadedly installed inside the second threaded hole 22. The positioning bearing 24 is fixedly installed on the top of the insertion block 21.

[0036] In this embodiment, the drill rod adjustment assembly 2 includes an insertion block 21 comprising a ratchet 30, a pawl 31, a slide bar 33, a second spring 34, and a pull handle 35. The ratchet 30 is fixedly installed on the outer side of the first turntable 4, and multiple slide bars 33 are slidably installed on the inner side of the fixing plate 32. The pawl 31 is fixedly installed on one side of the slide bar 33, one end of the second spring 34 is fixedly installed on one side of the pawl 31, and the other end of the second spring 34 is fixedly installed on one side of the fixing plate 32. The pull handle 35 is fixedly installed on the other side of the slide bar 33. The fixing base 3 is installed in a designated position by bolts. When drill rod processing is required, pulling the pull handle 35 moves the slide bar 33 and the pawl 31, allowing the pawl 31 to disengage from the ratchet 30. This controls the rotation of the mounting box 5 above the first turntable 4, and allows adjustment of the device's positioning angle.

[0037] In this embodiment, the drill rod adjustment assembly 2 also includes a lead screw 36 and a knob 37. The lead screw 36 is rotatably mounted inside the mounting box 5, and the knob 37 is fixedly mounted on the outside of one end of the lead screw 36. The movable frame 6 is threadedly mounted inside the lead screw 36.

[0038] In this embodiment, a through hole is provided at the top of the fixed cylinder 11, and the sliding cylinder 12 fits into the through hole; by allowing the sliding cylinder 12 to slide inside the fixed cylinder 11, the height of the positioning bearing 24 can be adjusted, and the fixing bolt 14 can be screwed into the first threaded hole 13 to fix the position of the sliding cylinder 12.

[0039] In this embodiment, a limiting groove is provided on one side of the mounting box 5, and the movable frame 6 is slidably installed inside the limiting groove. The movable frame 6 is L-shaped. The control knob 37 drives the lead screw 36 to rotate, and the movable frame 6 can be moved to a different position through the threaded engagement.

[0040] In this embodiment, the top of the fixed box 20 is provided with an insertion groove, and the insertion block 21 fits into the insertion groove. The positioning bearing 24 is inserted into the interior of the fixed box 20 through the insertion block 21. The locking bolt 23 can be controlled to enter the second threaded hole 22 to lock the insertion block 21. The second turntable 17 can be controlled to rotate around the rotating shaft 16 in front of the drill rod. After rotating to a specified angle, the first spring 19 can drive the positioning pin 18 to slide into the positioning hole 25 above the mounting base 15. This prevents the positioning bearing 24 from rotating during the auxiliary positioning process, so that the device can adjust a large angle while maintaining high stability and being easy to operate.

[0041] In this embodiment, a sliding hole is provided on one side of the fixing plate 32, and the sliding rod 33 is slidably installed inside the sliding hole. After adjusting the position of the mounting box 5, the control of the pull handle 35 can be released, which allows the second spring 34 to drive the pawl 31 to move, thereby allowing the pawl 31 to limit and lock the ratchet 30. The sliding rods 33 on both sides can provide lateral support force for the pawl 31, which can prevent the pawl 31 from loosening or displacing when it is limited, so that the locking effect is better.

[0042] The specific operation is as follows: the fixed base 3 is installed in the designated position with bolts. When drilling is required, pulling the handle 35 moves the slide bar 33 and pawl 31, allowing the pawl 31 to disengage from the ratchet 30. This allows the mounting box 5 above the first turntable 4 to rotate, adjusting the positioning angle of the device. After adjustment, releasing the handle 35 allows the second spring 34 to move the pawl 31, thus limiting and locking the pawl 31 against the ratchet 30. The slide bars 33 on both sides provide lateral support to the pawl 31, preventing it from loosening or shifting during the limiting process, resulting in a better locking effect. The control knob 37 rotates the lead screw 36, which, through the threaded engagement, moves the moving frame 6 to different positions. The sliding cylinder 12 slides inside the fixed cylinder 11, allowing the height of the positioning bearing 24 to be adjusted. The fixing bolt 14 is screwed into the first threaded hole 13 to fix the position of the sliding cylinder 12. The positioning bearing 24 is inserted into the fixed box 20 through the insertion block 21, and the locking bolt 23 is controlled to enter the second threaded hole 22 to lock the insertion block 21. The second turntable 17 can be controlled to rotate around the rotating shaft 16 in front of the drill rod. After rotating to a specified angle, the first spring 19 can drive the positioning pin 18 to slide into the positioning hole 25 above the mounting base 15, so that the positioning bearing 24 will not rotate during the auxiliary positioning process. This makes the device have a large adjustment angle, high stability, and is easy to operate.
