Description

Technical Field

[0001] The invention relates to the technical field of monorail cranes, and in particular to an automatic lubrication and wear monitoring device for a monorail crane in a coal mine tunnel. Background Art

[0002] Coal mine tunnel monorail crane is a kind of transportation equipment specially designed for transporting coal, materials and personnel underground in coal mines. It is mainly composed of motors, transmission devices, suspension devices, running wheels, tracks and control devices. Monorail cranes are widely used in coal mine tunnels because of their small footprint, easy installation and smooth operation. When the monorail crane moves on the track, in order to keep the wheels running safely and efficiently, it is usually necessary to lubricate and monitor the wear of the monorail crane track. However, due to the existing lubrication and wear monitoring of the monorail crane track in coal mine tunnels, the staff needs to use a track lubricator to spray the lubricant on the track and apply it to lubricate the monorail crane track, and monitor the wear of the track through the wear detector. The operation is time-consuming and labor-intensive, and the lubricant is easily splashed and wasted when sprayed on the track, resulting in low maintenance efficiency and quality of the monorail crane track.

[0003] Therefore, an automatic lubrication and wear monitoring device for a coal mine tunnel monorail crane has been developed, which can lubricate and monitor the track wear through the movement of the monorail crane, evenly apply the lubricant, and isolate and recover the splashed lubricant. Summary of the invention

[0004] In order to overcome the shortcomings of existing lubrication and wear monitoring of monorail crane tracks in coal mine tunnels, which are time-consuming and labor-intensive operation, and lubricant is easily splashed and wasted when sprayed on the track, resulting in low lubrication and maintenance efficiency and quality of the monorail crane track, the present invention provides an automatic lubrication and wear monitoring device for monorail cranes in coal mine tunnels, which can lubricate and monitor the wear of the track by moving the monorail crane, can evenly apply the lubricant, and can isolate and recover the splashed lubricant.

[0005] The technical solution is: an automatic lubrication and wear monitoring device for a monorail crane in a coal mine tunnel, comprising a track, a mounting frame, a connecting frame, a movable frame, a monitoring mechanism, a uniform mechanism and a collecting mechanism. The mounting frame is located below the track, and the left and right parts of the mounting frame are connected to two front and rear connecting frames, and the upper sides of the left and right parts of the mounting frame are connected to movable frames, and the movable frames are slidably matched with the mounting frame. The mounting frame is provided with a monitoring mechanism capable of monitoring and lubricating the track wear, the monitoring mechanism is provided with a uniform mechanism capable of evenly applying the lubricant, and the uniform mechanism is provided with a collecting mechanism capable of recovering excess lubricant.

[0006] In one of the embodiments, the monitoring mechanism includes a fixed frame, a supporting frame, a wear detector, a material storage barrel, a discharge pump, a material guide pipe and a nozzle. The left side of the mounting frame is connected to the fixed frame, the left part of the fixed frame is connected to the supporting frame, the upper side of the supporting frame is connected to the wear detector, the wear detector is engaged with the track, the middle part of the fixed frame is connected to the material storage barrel, the front and rear sides of the lower part of the material storage barrel are connected to the discharge pump, the discharge pump is connected to the material guide pipe, and the material guide pipe is connected to the nozzle. When the mounting frame moves, it drives the fixed frame to move, the supporting frame moves, so that the wear detector moves on the track, and the track is detected for wear. When the fixed frame moves, the discharge pump is started, so that the lubricant in the material storage barrel enters the material guide pipe and is then sprayed from the nozzle onto the track.

[0007] In one of the embodiments, a feeding pipe is provided on the front side of the storage barrel.

[0008] In one embodiment, the material guide tubes are all made of hose material.

[0009] In one of the embodiments, the uniformity mechanism includes a fixed block, an electric push rod, a connecting plate and an isolation cover. The fixed block is connected to the upper right side of the fixed frame, the electric push rod is connected to the fixed block, the connecting plate is connected to the telescopic end of the electric push rod, the front and rear parts of the connecting plate are connected to isolation covers, the nozzles are connected to adjacent isolation covers, and the isolation covers are engaged with the track. The electric push rod on the fixed block is started to push the connecting plate to move left and right, so that the isolation cover drives the nozzle to move left and right. When the nozzle sprays lubricant, the splashing lubricant is blocked by the isolation cover.

[0010] In one of the embodiments, a collecting mechanism is also included, which includes a guide rod, a scraper, a first pressure spring, a connecting pipe, a collecting box and a top frame. The left and right parts of the isolation cover are connected to the guide rods, and the scrapers are slidably connected between the two adjacent guide rods. The scrapers pass through the adjacent isolation covers, and the scrapers are connected to the first pressure springs between the connected guide rods. The lower sides of the isolation covers are connected to connecting pipes, and the collecting boxes are connected between the connecting pipes. The collecting boxes are connected to the fixed frame, and the top frames are connected to the front and rear sides of the left part of the fixed frame. The top frames are squeezed and matched with the adjacent scrapers. When the isolation cover moves left and right, the scrapers are driven to move left and right. When the scrapers contact the top frame, the top frame squeezes the scrapers to move outward, and the first pressure spring is squeezed and contracted. After the scrapers are separated from the top frame, the first pressure spring rebounds, causing the scrapers to reset, and then the scrapers move back and forth in the isolation cover to scrape off the lubricant attached to the isolation cover, and then the lubricant enters the collecting box from the connecting pipe.

[0011] In one of the embodiments, a smoothing mechanism is also included, which includes a support plate, a telescopic rod, a second pressure spring and a smoothing block. The front and rear sides of the right part of the fixed frame are connected to the support plates, the upper part of the support plates is connected to the telescopic rod, and the telescopic ends of the telescopic rods are connected to the smoothing blocks. The second pressure spring is connected between the smoothing blocks and the connected telescopic rods. The force of the second pressure spring ensures that the smoothing blocks on the telescopic rods always keep in contact with the track. When the lubricant is sprayed onto the track, the smoothing blocks spread the lubricant evenly.

[0012] In one of the embodiments, a protection mechanism is also included, which includes a guide frame, a sliding frame and a cleaning block. The guide frames are connected to the front and rear sides of the left part of the support frame. The sliding frames are slidably connected to the guide frames. The sliding frames are connected to adjacent isolation covers. The cleaning blocks are connected to the left sides of the sliding frames. The cleaning blocks are in contact with the tracks. When the isolation covers move left and right, the sliding frames are driven to move left and right on the guide frames, so that the cleaning blocks move left and right on the tracks.

[0013] In one of the embodiments, a cleaning mechanism is also included, which includes a fixed part, a rotating plate, a torsion force and a cleaning wheel. The upper and lower sides of the cleaning block are connected to fixed parts, and a rotating plate is rotatably connected between two adjacent fixed parts. Torsion springs are connected between the rotating plates and the connected fixed parts, and cleaning wheels are rotatably connected to the rotating plates. The cleaning wheels on the rotating plates are always kept in contact with the track by the force of the torsion springs, and the cleaning wheels are driven to move on the track when the cleaning block moves.

[0014] In one embodiment, the cleaning wheels are provided with bristles.

[0015] The beneficial effects are: 1. The present invention drives the movement of the fixed frame and the support frame while the mounting frame moves, so that the wear detector moves on the track to detect the wear of the track. When the fixed frame moves, the discharge pump is started to allow the lubricant in the storage barrel to enter the guide pipe and then be sprayed from the nozzle onto the track, thereby achieving the effect of being able to lubricate and monitor the wear of the track by moving the monorail crane, saving manpower and improving the efficiency of track maintenance.

[0016] 2. The present invention starts the electric push rod on the fixed block to push the connecting plate to move left and right, so that the isolation cover drives the nozzle to move left and right. When the nozzle sprays lubricant, the splashing lubricant is blocked by the isolation cover, so that the lubricant can be evenly sprayed onto the track, and the lubricant can be isolated to avoid splashing of the lubricant.

[0017] 3. The present invention scrapes off the lubricant attached to the isolation cover by reciprocating movement of the scraper in the isolation cover, and then the lubricant enters the collection box from the connecting pipe, thereby achieving the effect of being able to collect the lubricant in the isolation cover and reducing lubricant waste.

[0018] 4. The present invention uses the force of the second pressure spring to ensure that the smearing block on the telescopic rod always keeps in contact with the track. When the lubricant is sprayed onto the track, the smearing block smears the lubricant evenly, thereby achieving the effect of being able to spread the lubricant evenly on the track and ensuring that the lubricant is applied in place.

[0019] 5. The present invention drives the sliding frame to move left and right on the guide frame while the isolation cover moves left and right, so that the cleaning block moves left and right on the track, thereby achieving the effect of cleaning the track and avoiding affecting the normal operation of the monorail crane.

[0020] 6. The present invention uses the force of the torsion spring to keep the cleaning wheel on the rotating plate in contact with the track at all times. When the cleaning block moves, it drives the cleaning wheel to move on the track, thereby achieving the effect of cleaning the track and preventing dust from accumulating on the track.

The left side of the mounting frame 1 is connected to the fixed frame 41, the left part of the fixed frame 41 is connected to the support frame 42, the upper side of the support frame 42 is connected to the wear detector 43, the wear detector 43 is engaged with the track 0, the middle part of the fixed frame 41 is connected to the storage barrel 44, the front and rear sides of the lower part of the storage barrel 44 are connected to the discharge pump 45, the front side of the storage barrel 44 is provided with a feed pipe for adding materials, the discharge pump 45 is connected to the guide pipe 46, the guide pipe 46 is made of hose material and can be bent into different shapes, and the guide pipe 46 is connected to the nozzle 47.

[0035] like Figure 1 , Figure 4 and Figure 5As shown, the uniform mechanism 5 includes a fixed block 51, an electric push rod 52, a connecting plate 53 and an isolation cover 54. The fixed block 51 is connected to the upper right side of the fixed frame 41, the electric push rod 52 is connected to the fixed block 51, the connecting plate 53 is connected to the telescopic end of the electric push rod 52, the front and rear parts of the connecting plate 53 are connected to the isolation cover 54, the nozzles 47 are connected to the adjacent isolation covers 54, and the isolation covers 54 are snap-fitted with the track 0.

[0036] like Figure 1 , Figure 6 and Figure 7 As shown, it also includes a collecting mechanism 6, which includes a guide rod 61, a scraper 62, a first pressure spring 63, a connecting pipe 64, a collecting box 65 and a top frame 66. The left and right parts of the isolation cover 54 are connected to the guide rod 61, and the scraper 62 is slidably connected between two adjacent guide rods 61. The scraper 62 passes through the adjacent isolation covers 54. The first pressure spring 63 is connected between the scraper 62 and the connected guide rods 61. The lower side of the isolation cover 54 is connected to a connecting pipe 64, and the collecting box 65 is connected between the connecting pipes 64.

The front and rear sides of the left part of the fixed frame 41 are connected to the top frame 66, and the top frame 66 is squeezed and matched with the adjacent scrapers 62.

[0037] When using the present invention, firstly, the track 0 is installed in the driving area of ​​the monorail crane, and then the monorail crane is installed on the mounting frame 1 through the connecting frame 2, and then the moving frame 3 moves on the track 0 to drive the mounting frame 1 to move, so that the monorail crane runs. When the mounting frame 1 moves, it drives the fixed frame 41 to move, and the support frame 42 moves, so that the wear detector 43 moves on the track 0 to detect the wear of the track 0. When the fixed frame 41 moves, the discharge pump 45 is started, so that the lubricant in the storage barrel 44 enters the guide pipe 46, and then is sprayed from the nozzle 47 to the track 0, thereby achieving the effect of lubricating and monitoring the wear of the track 0 by moving the monorail crane, saving manpower, and improving the maintenance efficiency of the track 0. By using the uniform mechanism 5 of the device, the lubricant can be evenly sprayed onto the track 0. The electric push rod 52 on the fixed block 51 is started to push the connecting plate 53 to move left and right, so that the isolation cover 54 drives the nozzle 47 to move left and right. When the nozzle 47 sprays the lubricant, the splashing lubricant is blocked by the isolation cover 54, thereby achieving the effect of being able to spray the lubricant evenly onto the track 0 and isolating the lubricant to prevent the lubricant from splashing. By using the collecting mechanism 6 of the present device, the lubricant in the isolation cover 54 can be collected. When the isolation cover 54 moves left and right, the scraper 62 is driven to move left and right. When the scraper 62 contacts the top frame 66, the top frame 66 squeezes the scraper 62 to move outward, and the first pressure spring 63 is squeezed and contracted. After the scraper 62 is separated from the top frame 66, the first pressure spring 63 rebounds, causing the scraper 62 to reset, thereby causing the scraper 62 to move back and forth in the isolation cover 54, scraping off the lubricant attached to the isolation cover 54, and then the lubricant enters the collection box 65 from the connecting pipe 64, thereby collecting the lubricant in the isolation cover 54 and reducing the waste of lubricant.

[0039] The lubricant can be evenly spread by using the smearing mechanism 7 of the device. The smearing block 74 on the telescopic rod 72 is always kept in contact with the track 0 through the force of the second pressure spring 73. When the lubricant is sprayed onto the track 0, the smearing block 74 smears the lubricant evenly, thereby spreading the lubricant evenly on the track 0 and ensuring that the lubricant is applied in place.

[0040] like Figure 1 and Fig. 9As shown, a protection mechanism 8 is also included, and the protection mechanism 8 includes a guide frame 81, a sliding frame 82 and a cleaning block 83.

The sliding frames 82 are connected to the adjacent isolation covers 54. The cleaning blocks 83 are connected to the left sides of the sliding frames 82, and the cleaning blocks 83 are in contact with the track 0.

[0041] By using the protection mechanism 8 of the device, the track 0 can be cleaned. When the isolation cover 54 moves left and right, it drives the sliding frame 82 to move left and right on the guide frame 81, so that the cleaning block 83 moves left and right on the track 0, thereby cleaning the track 0 and avoiding affecting the normal operation of the monorail crane.

[0042] like Figure 1 and Fig.10 As shown, a cleaning mechanism 9 is also included, and the cleaning mechanism 9 includes a fixing member 91, a rotating plate 92, and a torsion and cleaning wheel 94. The cleaning block 83 is connected to fixing members 91 on both sides, and a rotating plate 92 is rotatably connected between two adjacent fixing members 91.
