Description

Technical Field

[0001] This invention relates to the field of coal mine lighting equipment technology, and in particular to a mine tunnel light used in coal mine operations. Background Technology

[0002] In the process of mining deep coal mines, it is often necessary to excavate tunnels. Since coal mine tunnels are generally very deep underground, very dark, long and narrow, and the height of the tunnels is not completely consistent, with many bends, appropriate lighting devices need to be installed on the inside of the tunnels so that coal miners can work normally inside the tunnels.

[0003] In existing technologies, coal mine roadways have many bends. When miners work in the roadways, they need to frequently switch work faces. Since the fixed lighting fixtures cannot be moved, there are situations where work needs to be stopped and wait due to insufficient lighting, making continuous work impossible and reducing work efficiency. In addition, when installing the lighting fixture brackets at the corners of the roadways, manual tools are required to fix the bolts to both sides of the corners on the inner wall of the roadway. However, repeatedly retrieving and using tools takes a lot of time, making it impossible to quickly install the lighting fixture brackets on both sides of the corners on the inner wall of the roadway, thus affecting the installation efficiency of the lighting fixture brackets. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the prior art by proposing a mine tunnel light for coal mining.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a mine tunnel light for coal mining, comprising a coal mine roadway, wherein an irregularly shaped track is connected to the inner wall of the coal mine roadway via a quick-assembly mechanism, a moving rod is connected to the irregularly shaped track via a position adjustment mechanism, a lamp housing is connected to the moving rod via a buffer protection mechanism, a lamp shade is fixedly connected to the bottom end of the lamp housing, and a pneumatic cleaning mechanism for cleaning the outer surface of the lamp shade is provided on the lamp housing.

[0006] The quick-installation mechanism is used to quickly install irregularly shaped tracks on the inner wall of coal mine roadways;

[0007] The position adjustment mechanism includes fixed side plates fixedly connected to both ends of the irregular track. A drive shaft is rotatably connected to each of the two fixed side plates. A winding drum is fixedly connected to the outer wall of each of the two drive shafts. A steel wire rope is wound around each of the two winding drums. The two steel wire ropes are fixedly connected to a moving rod. One winding drum is used for winding and the other is used for unwinding, thereby moving the lamp housing back and forth and changing the position of the lamp.

[0008] The buffer protection mechanism is used to buffer the vibration force generated when the lamp changes position.

[0009] Preferably, the quick-installation mechanism includes a first installation slot and a second installation slot formed on both sides of the inner wall of the coal mine roadway, and further includes a limiting post and a fixing sleeve fixedly connected to both sides of one end of the irregular track. The limiting post and the second installation slot are adapted to each other. The top of the fixing sleeve is provided with a square hole, and a sliding pushing block is provided on the inner wall of the square hole. The bottom end of the pushing block is fixedly connected with a telescopic post. The telescopic post and the first installation slot are adapted to each other. A telescopic spring is fixedly connected between the telescopic post and the fixing sleeve.

[0010] Preferably, the position adjustment mechanism further includes an irregular groove formed at one end of the outer side of the irregular track. Two guide grooves are formed on the upper and lower sides of the inner wall of the irregular groove. Guide columns are provided on the inner walls of both sets of guide grooves. Both sets of guide columns are fixedly connected to the moving rod. Motors are fixedly connected to one end of the two fixed side plates on one side. The two motors and two drive shafts are fixedly connected respectively.

[0011] Preferably, the buffer protection mechanism includes a circular groove formed at the bottom end of the movable rod, with sliding grooves connected to the four sides of the inner wall of the circular groove, and sliders provided on the inner walls of the four sliding grooves. A circular column is fixedly connected between the four sliders, and the circular column is fixedly connected to the lamp housing.

[0012] Preferably, two damping devices B and two damping springs B are fixedly connected to the bottom ends of the four grooves respectively. The two damping devices B and the two damping springs B are symmetrically distributed. The two damping devices B and the two damping springs B are all fixedly connected to the slider. Two damping devices A and two damping springs A are fixedly connected between the circular column and the circular groove respectively. The two damping devices A and the two damping springs A are symmetrically distributed.

[0013] Preferably, the pneumatic cleaning mechanism includes air vents passing through both sides of the outer wall of the lamp housing, with the two air vents symmetrically distributed. A rotating shaft is rotatably connected to the top of the inner wall of the lamp housing, and multiple fan blades are fixedly connected to the bottom of the outer wall of the rotating shaft. A synchronous pulley B is fixedly connected to the top of the outer wall of the rotating shaft.

[0014] Preferably, a fixing plate is fixedly connected to both the upper and lower sides of the outer wall of the lamp housing, and a drive shaft is rotatably connected to the fixing plate. A synchronous pulley A is fixedly connected to the top of the outer wall of the drive shaft, and the synchronous pulley A and the synchronous pulley B are connected by a synchronous belt.

[0015] Preferably, a rotating ring is rotatably connected to the bottom end of the lamp housing corresponding to both sides of the lampshade. A toothed ring is fixedly connected to the outer wall of the rotating ring. A gear is meshed with the outer diameter of the toothed ring. The gear and the transmission shaft are fixedly connected. A cleaning plate is fixedly connected to the bottom end of the rotating ring. A cleaning sponge is fixedly connected to the end of the cleaning plate near the lampshade.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. Through the set quick-installation mechanism, the limiting post can be inserted into the second installation slot first. Since the limiting post and the second installation slot are square, the irregular guide rail can be limited. Then, the telescopic post is inserted into the first installation slot to limit the irregular guide rail again. Thus, the irregular guide rail can be quickly installed on both sides of the corner of the inner wall of the tunnel, improving the installation efficiency.

[0018] 2. Through the set position adjustment mechanism, the motors on both sides can be controlled to rotate synchronously. At this time, the wire rope on one side is in the winding state and the wire rope on the other side is in the unwinding state, thereby changing the position of the moving rod. Therefore, the position of the lamp can be adjusted as needed to move the lamp to a new work point, reduce downtime due to insufficient lighting, enable continuous operation, and improve work efficiency.

[0019] 3. Through the set buffer protection mechanism, the vibration force generated when the lamp moves can be buffered by the cooperation of damper A, damper spring A, damper B and damper spring B, protecting the electronic components inside the lamp and thus extending its service life.

[0020] 4. The pneumatic cleaning mechanism allows air to pass through the vents when the lamp moves. This airflow drives the fan blades and transmits power to the cleaning plate via a transmission mechanism. The cleaning plate rotates around the center of the lampshade, allowing the cleaning sponge on the plate to clean the outer surface of the lampshade, preventing coal dust from falling onto it and ensuring the brightness of the lamp. At the same time, the internal temperature of the lamp can be cooled by air cooling to prevent excessive internal temperature and extend the lifespan of the internal electronic components.

[0034] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0035] like Figures 1-12The diagram shows a mine tunnel light for coal mining, comprising a coal mine roadway 1. A shaped track 3 is connected to the inner wall of the roadway 1 via a quick-installation mechanism. A moving rod 15 is connected to the shaped track 3 via a position adjustment mechanism. A lamp housing 17 is connected to the moving rod 15 via a buffer protection mechanism. A lamp shade 31 is fixedly connected to the bottom of the lamp housing 17. The lamp housing 17 is equipped with a pneumatic cleaning mechanism for cleaning the outer surface of the lamp shade 31. The quick-installation mechanism is used to quickly install the shaped track 3 onto the inner wall of the coal mine roadway 1. The position adjustment mechanism includes… Fixed side plates 6 are fixedly connected to both ends of the irregular track 3. A drive shaft is rotatably connected to each of the two fixed side plates 6. A winding drum 7 is fixedly connected to the outer wall of each of the two drive shafts. A steel wire rope 8 is wound around each of the two winding drums 7. The two steel wire ropes 8 are fixedly connected to the moving rod 15. The steel wire rope 8 passes through the irregular track 3. One winding drum 7 is used for winding and the other for unwinding, thereby moving the lamp housing 17 back and forth and changing the position of the lamp. The buffer protection mechanism is used to buffer the vibration force generated when the lamp changes position.

[0036] like Figure 11 , Figure 12 As shown, the quick-installation mechanism includes a first mounting slot 36 and a second mounting slot 37 located on both sides of the inner wall of the coal mine roadway 1. It also includes a limiting post 5 and a fixing sleeve 2 fixedly connected to both sides of one end of the irregularly shaped track 3. The limiting post 5 and the second mounting slot 37 are shaped to match each other. A square hole 10 is provided at the top of the fixing sleeve 2, and a sliding push block 11 is provided on the inner wall of the square hole 10. A telescopic post 4 is fixedly connected to the bottom of the push block 11. The telescopic post 4 is shaped to match the first mounting slot 36, and a telescopic spring 12 is fixedly connected between the telescopic post 4 and the fixing sleeve 2. The first mounting slot 36 and the second mounting slot 37 are located on both sides of the corner of the coal mine roadway 1, and are set at a 90-degree angle. The irregularly shaped track 3 consists of one arc-shaped section and two straight sections, with the arc-shaped section at a 90-degree angle. Therefore, the lamp can move back and forth on both sides of the corner of the coal mine roadway 1. The push block 11 can be limited by the square hole 10.

[0037] like Figure 3 , Figure 5 As shown, the position adjustment mechanism also includes a shaped groove 13 located at one end of the outer side of the shaped track 3. Two guide grooves 14 are respectively formed on the upper and lower sides of the inner wall of the shaped groove 13. Guide posts 16 are provided on the inner walls of both sets of guide grooves 14, and both sets of guide posts 16 are fixedly connected to the moving rod 15. Motors 9 are fixedly connected to one end of each of the two fixed side plates 6 on one side, and the two motors 9 are fixedly connected to the two drive shafts respectively. The motors 9 on both sides are controlled by a synchronous controller to rotate synchronously, thus synchronously rotating the drive shafts. Due to the cooperation of the guide grooves 14 and guide posts 16, the moving rod 15 can be limited to prevent deflection during movement and avoid affecting the movement.

[0038] like Figure 6 , Figure 7 As shown, the buffer protection mechanism includes a circular groove 20 at the bottom of the movable rod 15. The inner walls of the circular groove 20 are connected to four sliding grooves 22. Each of the four sliding grooves 22 has a slider 23 on its inner wall. A circular column 18 is fixedly connected between the four sliders 23. The circular column 18 is fixedly connected to the lamp housing 17. Two damping devices B38 and two damping springs B39 are fixedly connected to the bottom of each of the four sliding grooves 22. The two damping devices B38 and two damping springs B39 are symmetrically distributed. Both damping devices B38 and two damping springs B39 are fixedly connected to the sliders 23. Two damping devices A19 and two damping springs A21 are fixedly connected between the circular column 18 and the circular groove 20. The two damping devices A19 and two damping springs A21 are symmetrically distributed. With the cooperation of damper A19, damping spring A21, damper B38 and damping spring B39, the vibration generated when the lamp moves can be buffered, preventing the vibration from acting directly on the lamp. Therefore, the internal electronic components of the lamp can be protected and the service life of the lamp can be extended. The sliding groove 22 and slider 23 can limit the circular column 18 to prevent rotation during buffering.

[0039] like Figure 6 , Figure 8 , Figure 9 , Figure 10 As shown, the pneumatic cleaning mechanism includes air vents 27 extending through both sides of the outer wall of the lamp housing 17. Filter plates are fixedly connected to the inner walls of both air vents 27. These filters block coal dust, preventing it from entering the lamp. The filter plates are made of polyurethane screens, which are high-strength, high-toughness, wear-resistant, and oil-resistant. Their surface adhesion reduces particle accumulation and clogging. The two air vents 27 are symmetrically distributed. A rotating shaft 34 is rotatably connected to the top of the inner wall of the lamp housing 17. Multiple fan blades 33 are fixedly connected to the bottom of the outer wall of the rotating shaft 34. A synchronous pulley B35 is fixedly connected to the top of the outer wall of the rotating shaft 34. Fixed plates 28 are fixedly connected to both the top and bottom sides. A drive shaft 25 is rotatably connected to the fixed plates 28. A synchronous pulley A24 is fixedly connected to the top of the outer wall of the drive shaft 25. The synchronous pulley A24 and the synchronous pulley B35 are connected by a synchronous belt. Rotating rings 30 are rotatably connected to the bottom of the lamp housing 17 corresponding to the two sides of the lamp cover 31. A toothed ring 29 is fixedly connected to the outer wall of the rotating ring 30. A gear 26 is meshed with the outer diameter of the toothed ring 29. The gear 26 is fixedly connected to the drive shaft 25. A cleaning plate 32 is fixedly connected to the bottom of the rotating ring 30. A cleaning sponge is fixedly connected to the end of the cleaning plate 32 near the lamp cover 31.

[0040] Working principle: First, during installation, the telescopic column 4 is retracted into the fixed sleeve 2. Then, the limiting column 5 is inserted into the second mounting groove 37. Since the limiting column 5 and the second mounting groove 37 are square, they can initially limit the irregular track 3. The telescopic column 4 is aligned with the first mounting groove 36. Then, the control of the telescopic column 4 is released, and the telescopic column 4 is locked into the first mounting groove 36 by the telescopic spring 12. This allows for the quick completion of the installation of the irregular track 3, thereby improving installation efficiency.

[0041] In use, the synchronous controller controls the motors 9 on both sides to rotate synchronously. Therefore, the drive shafts on both sides rotate synchronously in a clockwise or counterclockwise direction. Thus, the wire rope 8 on one side of the winding drum 7 is in the unwinding state, while the wire rope 8 on the other side of the winding drum 7 is in the winding state. At the same time, due to the cooperation of the guide groove 14 and the guide column 16, the moving rod 15 moves back and forth and adjusts the position of the lamp as needed, so that the lamp is adjusted to a new working point, reducing downtime due to insufficient lighting, enabling continuous operation and improving work efficiency.

[0042] When the lamp moves, it vibrates. The vibration is buffered by the combined action of damper A19, damping spring A21, damper B38, and damping spring B39, preventing the vibration from acting on the lamp, protecting the internal electronic components, and extending the lamp's lifespan. During movement, air enters the lamp through a filter on one side and exits through another, creating airflow inside the lamp. This airflow drives the fan blades 33, causing the shaft 34 to rotate. Since the synchronous pulley B35 is fixedly connected to the shaft 34, it will... The synchronous wheel B35 rotates, while the synchronous wheel A24 rotates synchronously via a synchronous belt. The diameter of the synchronous wheel A24 is larger than that of the synchronous wheel B35, which can reduce speed. The synchronous wheel A24 drives the drive shaft 25 and gear 26 to rotate, and the gear 26 drives the gear ring 29 and rotating ring 30 to rotate, causing the cleaning plate 32 to rotate around the center of the lamp cover 31. Therefore, the outer surface of the lamp cover 31 can be cleaned to ensure the brightness of the lamp. The filter plate can filter coal dust to prevent coal dust from entering the lamp and protect the electronic components inside the lamp.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
