Technical Field
[0001] This utility model relates to the field of rock drill chain technology, specifically a lubrication oil injection structure for a rock drill chain propulsion system. Background Technology
[0002] As an essential piece of equipment in tunnel and rock mining, the chain plays a crucial role in the transmission system of a rock drill. The performance of the chain directly affects the working efficiency and service life of the rock drill. Different types of chains have different lubrication requirements. For example, closed chains may be more suitable for dry lubrication, while open chains usually use lubricating oil or grease.
[0003] During the installation of lubrication equipment, commonly used clamping and mounting mechanisms often suffer from insufficient angle adjustment capabilities. This makes it difficult to quickly and accurately adapt to mounting components of varying shapes and sizes, significantly reducing the equipment's installation efficiency and flexibility. Furthermore, due to the lack of an effective limiting mechanism, the clamping and mounting mechanism is prone to accidental rotation during operation. This not only affects the stability of the clamping but may also damage the equipment or pose safety hazards. Therefore, we provide a lubrication injection structure for a rock drill chain propulsion system to address these issues. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a lubrication oil injection structure for a rock drill chain propulsion system.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a lubricating oil injection structure for a rock drill chain propulsion system, comprising a chain body, two cleaning brushes respectively attached to both sides of the chain body, and a working box rotatably connected to both ends of the cleaning brushes, with an oil injection mechanism rotatably connected inside the working box. A set of symmetrical support columns is fixedly connected to the top surface of the oil injection mechanism, and a threaded rod is rotatably connected inside the support columns. A bevel gear one is fixedly connected to the outer wall of the threaded rod, and a drive rod is rotatably connected to the outer side of the support columns. A bevel gear two is fixedly connected to one end of the drive rod, and the bevel gear two meshes with the bevel gear one. A lifting column is threadedly connected to the outer wall of the threaded rod, and a limit mechanism is rotatably connected to the top of the lifting column.
[0006] The aforementioned limiting mechanism includes a rotating rod, a gear, a locking rod, a T-shaped rod, and a spring. The outer wall of the rotating rod is fixedly connected to the inside of the gear, and one end of the locking rod is engaged with the tooth angle of the gear. The other end of the locking rod is fixedly connected to one end of the T-shaped rod, and one end of the spring is fixedly connected to one end of the locking rod.
[0007] As described above, the bottom end of the rotating rod is rotatably connected to the top end of the lifting column, and the end of the spring away from the locking rod is fixedly connected to the inner wall of the lifting column.
[0008] As described above, the bottom end of the clamping rod is slidably connected to the inside of the lifting column, the top end of the rotating rod is fixedly connected to a support plate, and the top end of the support plate is slidably connected to two clamping blocks, one end of which is fixedly connected to a pull rod.
[0009] As described above, two support blocks are fixedly connected to the top of the support plate, and springs are fixedly connected to the opposite sides of the support blocks and clamping blocks. The outer wall of the pull rod is movably connected to the inside of the support block.
[0010] The aforementioned oil injection mechanism includes an oil injection wheel, a rotating rod II, a fixed block, a guide block, and an oil guide pipe. The interior of the oil injection wheel is fixedly connected to the outer wall of the rotating rod II, and the outer wall of the rotating rod II is fixedly connected to the interior of two fixed blocks respectively. The inner wall of the oil injection wheel is fixedly connected to the bottom end of two guide blocks respectively. An oil guide groove is provided inside the rotating rod II, and the inlet of the oil guide groove is fixedly connected to the outlet of the oil guide pipe. The outlet of the oil guide groove faces upward towards the guide block.
[0011] As described above, one end of each of the two fixed blocks is fixedly connected to the inside of the working box, both ends of the second rotating rod are rotatably connected to the inside of the working box, an oil storage tank and an oil pump are fixedly connected to the top surface of the working box respectively, and the oil inlet of the oil guide pipe is fixedly connected to the oil outlet of the oil pump.
[0012] Compared with existing technologies, the lubrication oil injection structure of this rock drill chain propulsion system has the following advantages:
[0013] I. This utility model, through the setting of a limiting mechanism, rotates the first rotating rod, causing the clamping block on the support plate to rotate to an appropriate angle. Then, the pull rod is released, and the rebound force of the second spring causes the clamping block to automatically reset, thereby firmly clamping the frame of the rock drill. At the same time, the T-shaped rod is released, and the rebound force of the first spring accurately rebounds the clamping rod to the tooth angle of the gear, reliably limiting the first rotating rod and preventing its accidental rotation. This not only allows the clamping block to easily adapt to the needs of different installation parts, but also effectively prevents the clamping block from shifting due to uncontrolled rotation through a reliable limiting mechanism, thereby improving the stability of the clamping and installation of the oil injection equipment.
[0014] II. This utility model, through its oil injection mechanism, uses a controller to start an oil pump, drawing lubricating oil from the oil storage tank into the oil guide pipe, and then guiding it through the oil guide groove to the guide block. The lubricating oil drips along the oil injection wheel into the chain body, while simultaneously starting the chain body to rotate, achieving automatic lubrication and maintenance. During this process, a dust removal brush cleans the chain body, ensuring that the lubricating oil is quantitatively and evenly delivered to the chain body, avoiding the unevenness and leakage problems of manual lubrication, and reducing improper lubrication caused by human error, further improving the operating efficiency and reliability of the equipment.

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] like Figure 1-6 As shown, this utility model provides a technical solution: a lubricating oil injection structure for a rock drill chain propulsion system, including a chain body 1, two cleaning brushes 2 respectively attached to both sides of the chain body 1, and a working box 3 rotatably connected to both ends of the cleaning brushes 2, and an oil injection mechanism 5 rotatably connected inside the working box 3, a set of left and right symmetrical support columns 6 fixedly connected to the top surface of the oil injection mechanism 5, and a threaded rod 7 rotatably connected inside the support column 6, a bevel gear 8 fixedly connected to the outer wall of the threaded rod 7, and a drive rod 9 rotatably connected to the outer side of the support column 6, a bevel gear 10 fixedly connected to one end of the drive rod 9, the bevel gear 10 meshing with the bevel gear 8, a lifting column 11 threadedly connected to the outer wall of the threaded rod 7, and a limit mechanism 4 rotatably connected to the top of the lifting column 11.
[0025] First, place the chain body 1 into the work box 3. Then, adjust the height of the lifting column 11 according to the position of the rock drill frame. Next, rotate the drive rod 9 to drive the bevel gear 10 to rotate, which in turn causes the bevel gear 8 meshing with it to drive the threaded rod 7 to rotate, realizing the lifting movement of the lifting column 11 within the support column 6. This allows for adjustment of the height of the lifting column 11, effectively adapting to the positional requirements of different rock drill frames and improving the adaptability and flexibility of the equipment. Second, rotate the rotating rod 401 to drive the clamping block 13 on the support plate 12 to rotate to an appropriate angle. Then, release the pull rod 14, and the rebound force of the spring 2 causes the clamping block 13 to automatically return to its original position, thus firmly clamping the rock drill frame. At the same time, release the limiting mechanism 4, causing the limiting mechanism 4 to lock the clamping block 11. 3. Limiting the movement prevents accidental rotation. This not only allows the clamping block 13 to easily adapt to the needs of different installation parts, but also reduces the displacement of the clamping block 13 due to uncontrolled rotation through the reliable limiting mechanism 4, thereby improving the stability of clamping installation. Finally, the oil pump 19 is started by the controller to draw the lubricating oil in the oil tank 18 into the oil injection mechanism 5, so that the lubricating oil drips onto the chain body 1 along the oil injection mechanism 5. At the same time, the chain body 1 is started to rotate, realizing automatic lubrication and maintenance of the lubricating oil. During this process, the dust removal brush 2 cleans the chain body 1 along with the chain body 1, ensuring that the lubricating oil can be delivered quantitatively and evenly into the chain body 1, avoiding the unevenness and omission problems of manual lubrication, and reducing improper lubrication caused by human operation errors.
[0026] like Figure 1-4As shown, the limiting mechanism 4 includes a rotating rod 401, a gear 402, a locking rod 403, a T-shaped rod 404, and a spring 405. The outer wall of the rotating rod 401 is fixedly connected to the inside of the gear 402, and one end of the locking rod 403 engages with the tooth angle of the gear 402. The other end of the locking rod 403 is fixedly connected to one end of the T-shaped rod 404. One end of the spring 405 is fixedly connected to one end of the locking rod 403. The bottom end of the rotating rod 401 is rotatably connected to the top end of the lifting column 11, and the spring 405 is away from the locking rod 405. One end of 03 is fixedly connected to the inner wall of the lifting column 11. The bottom end of the clamping rod 403 is slidably connected to the inside of the lifting column 11. The top end of the rotating rod 401 is fixedly connected to the support plate 12, and the top end of the support plate 12 is slidably connected to two clamping blocks 13. One end of the clamping block 13 is fixedly connected to the pull rod 14. The top end of the support plate 12 is fixedly connected to two support blocks 15. The opposite sides of the support block 15 and the clamping block 13 are fixedly connected to the spring 16. The outer wall of the pull rod 14 is movably connected to the inside of the support block 15.
[0027] Rotating the first rotating rod 401 causes the clamping block 13 on the support plate 12 to rotate to an appropriate angle. Then, releasing the pull rod 14 causes the clamping block 13 to automatically reset due to the rebound force of the second spring, thus firmly clamping the frame of the rock drill. At the same time, releasing the T-shaped rod 404 causes the rebound force of the first spring 405 to accurately return the clamping rod 403 to the tooth angle of the gear 402, reliably limiting the first rotating rod 401 and preventing it from rotating accidentally. This not only allows the clamping block 13 to easily adapt to the needs of different installation parts, but also reduces the displacement of the clamping block 13 due to uncontrolled rotation through the reliable limiting mechanism 4, thereby improving the stability of the clamping installation.
[0028] like Figure 1 , Figure 2 Figure 5 and Figure 6 As shown, the oil injection mechanism 5 includes an oil injection wheel 501, a rotating rod 502, a fixed block 503, a guide block 504, and an oil guide pipe 505. The interior of the oil injection wheel 501 is fixedly connected to the outer wall of the rotating rod 502, and the outer wall of the rotating rod 502 is fixedly connected to the interior of the two fixed blocks 503 respectively. The inner wall of the oil injection wheel 501 is fixedly connected to the bottom end of the two guide blocks 504 respectively. An oil guide groove 17 is provided inside the rotating rod 502, and the inlet of the oil guide groove 17 is fixedly connected to the outlet of the oil guide pipe 505. The outlet of the oil guide groove 17 faces upward towards the guide block 504. One end of each of the two fixed blocks 503 is fixedly connected to the interior of the working box 3. Both ends of the rotating rod 502 are rotatably connected to the interior of the working box 3. An oil storage tank 18 and an oil pump 19 are fixedly connected to the top surface of the working box 3 respectively. The oil inlet of the oil guide pipe 505 is fixedly connected to the oil outlet of the oil pump 19.
[0029] The oil pump 19 is started by the controller, which draws the lubricating oil in the oil tank 18 into the oil guide pipe 505, and then guides it into the guide block 504 through the oil guide groove 17. The lubricating oil drips onto the chain body 1 along the oil injection wheel 501. At the same time, the chain body 1 is started to rotate, realizing automatic lubrication and maintenance of the lubricating oil. During this process, the dust cleaning brush 2 cleans the chain body 1, ensuring that the lubricating oil can be delivered quantitatively and evenly into the chain body 1, avoiding the unevenness and leakage problems of manual lubrication.
[0030] Working principle: First, place the chain body 1 into the work box 3. Then, adjust the height of the lifting column 11 according to the position of the rock drill frame. Next, by rotating the drive rod 9, the bevel gear 10 is rotated, which in turn causes the bevel gear 8 meshing with it to rotate the threaded rod 7, realizing the lifting movement of the lifting column 11 within the support column 6, thereby adjusting the height of the lifting column 11. Next, rotate the rotating rod 401 to rotate the clamping block 13 on the support plate 12 to an appropriate angle. Then, release the pull rod 14, and the rebound force of the spring 2 causes the clamping block 13 to automatically return to its original position, thus firmly clamping the rock drill frame. At the same time, release the T-shaped rod. 404, the rebound force of spring 405 accurately rebounds the lever 403 to the tooth angle of gear 402, reliably limiting the rotation of lever 401 and preventing it from rotating accidentally. Finally, the controller starts the oil pump 19 to draw the lubricating oil in the oil tank 18 into the oil guide pipe 505, and then guides it to the guide block 504 through the oil guide groove 17. The lubricating oil drips along the oil injection wheel 501 onto the chain body 1, and at the same time starts the chain body 1 to rotate, realizing the automatic lubrication and maintenance of the lubricating oil. During this process, the dust cleaning brush 2 cleans the chain body 1, ensuring that the lubricating oil can be quantitatively and evenly delivered into the chain body 1.
