Description

Technical Field

[0001] This invention relates to a mining machine and its grease cleaning system and method of use, belonging to the field of mining machinery. Background Technology

[0002] Mining excavators use large slewing bearings to rotate the equipment. Due to the size of the equipment, the amount of grease required for rotation is huge. More and more manufacturers are abandoning the traditional oil bath structure and using small independent motor lubrication covers to store the grease in the independent covers.

[0003] This type of structure is lightweight and independent, and the grease is not easily contaminated. However, because it lacks a sealed oil sump, grease will continuously drip down onto the lower frame during use, requiring manual cleaning after long-term accumulation. For equipment with a relatively low overall height, manual cleaning is relatively easy, but for equipment with a high frame, even exceeding 2 meters, manual cleaning becomes more difficult. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a mining machinery and its grease cleaning system and method, enabling service personnel to easily clean the grease from high-rise mining equipment without the aid of tools.

[0011] In some embodiments, the handrail includes a single handrail and a two-way handrail. The single handrail is fixed to the middle of the side of the adjustment plate, with a gap between the single handrail and the side of the adjustment plate to achieve side gripping. The two-way handrail is arranged at the lower part of the adjustment plate and is fixed together with the pulley seat and the adjustment plate.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0024] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0025] For equipment with a relatively low overall height, manual cleaning is relatively easy. However, for equipment with a high frame, even exceeding 2 meters in height, manual cleaning becomes much more difficult. Therefore, as... Figure 1 , Figure 2As shown, the present invention provides a grease cleaning system for mining machinery, which allows service personnel to easily clean grease from high-altitude mining equipment without the aid of tools.

[0026] The grease cleaning system 1 includes a grease collection chamber 7, an adaptive adjustment cleaning device, a guide assembly 3, a connecting base 13, and a handle 14. The grease collection chamber 7 is an annular groove structure located below the rotary motor to collect and store grease dripping from the upper rotary motor lubrication cover 2. The grease collection chamber 7 has at least one oil drain channel. The adaptive adjustment cleaning device includes a scraper 11 and an adaptive adjuster 12 mounted together. The scraper 11 is disposed in the grease collection chamber 7, and the scraper 11 moves within the grease collection chamber 7. The grease in the cavity is pushed towards the oil drain channel; the adaptive adjuster 12 has a height self-adjustment function to adapt to the grease scraper 11 at different heights; the guide assembly 3 is set on the grease collection cavity 7 and has a path guiding function; the connecting base 13 is set on the guide assembly 3, and the two form a kinematic pair; the connecting base 13 is connected to the adaptive adjuster 12 and the handle 14, and pushing the handle 14 drives the connecting base 13 to move on the guide assembly 3, thereby driving the grease scraper 11 to move, pushing the grease in the cavity towards the oil drain channel, and the grease is discharged out of the frame through the oil drain channel.

[0027] As can be seen from the above, this invention is mainly applied to mining machinery and equipment with high frame height. It makes full use of the frame structure to construct a grease collection space, and adopts an adaptive adjustment cleaning device, guide components and handles to achieve adaptive adjustment cleaning of grease, which makes it convenient for service personnel to quickly clean grease, improves maintenance and cleaning efficiency, and reduces the risk of pipeline oil contamination.

[0028] The following provides a further explanation of the specific structure of the grease collection chamber described above.

[0029] like Figure 1 , Figure 2 As shown, the grease collection chamber 7 is located below the rotary motor and is formed by the frame top plate 6, the frame rotary seat 5 fixed to the outer ring of the frame top plate 6, and the grease baffle 4 fixed to the inner ring of the frame top plate 6. The frame top plate 6 has multiple oil drain holes I8 located on the same circumference along its entire circumference, and the inner side upright plate of the frame has multiple oil drain holes II9. Each oil drain hole II9 corresponds to one oil drain hole I8, and a drain channel is formed between the two holes through a pipeline connection.

[0030] It should be noted that the location of the oil drain hole is not unique and can be determined according to actual needs.

[0031] The following provides a further explanation of the specific structure of the aforementioned guidance components.

[0032] like Figure 3 As shown, the guide assembly 3 includes a bearing seat 31 and a guide slide rail 32. The guide slide rail 32 is fixed to the top surface of the grease baffle 4 and extends circumferentially along the top surface of the grease baffle 4 to form an annular slide rail. The bearing seat 31 is snapped onto the guide slide rail 32, and a sliding pair is formed between the two. The connecting base 13 is installed on the bearing seat 31. Pushing the handle 14 causes the connecting base 13 to slide on the guide slide rail 32, thereby causing the grease scraper 11 to rotate circumferentially.

[0033] The following is a further explanation of the specific structure of the aforementioned grease scraper.

[0034] like Figure 4 As shown, the grease scraper 11 includes a scraper plate 102, an outer guide plate 101, and an inner guide plate 103. The scraper plate 102 is disposed on the top plate 6 of the frame between the frame swivel seat 5 and the grease baffle 4. The scraper plate 102 is connected to the adaptive adjuster 12. The outer guide plate 101 is fixed to the outer end of the scraper plate 102 and fits with the inner circumferential side of the frame swivel seat 5. The inner guide plate 103 is fixed to the inner end of the scraper plate 102 and fits with the outer circumferential side of the grease baffle 4. The inner and outer guide plates 101 and 103 assist in guiding the scraper plate 102 to slide along the annular cavity.

[0035] The following provides a further explanation of the specific structure of the adaptive regulator described above.

[0036] like Figure 5 As shown, the adaptive adjuster 12 includes a connecting plate 201 at the top, a pressure plate 202 in the middle, multiple adjusting components between the connecting plate 201 and the pressure plate 202, and two clamping plates 203 at the bottom. The connecting plate 201 is used to connect to the connecting base 13. The two clamping plates 203 are fixed opposite to each other on the bottom surface of the pressure plate 202, forming a U-shaped installation space between the two clamping plates 203 and the pressure plate 202. Anti-wear pads 204 and 205 are installed on the top and side surfaces of the U-shaped installation space. All anti-wear pads 204 and 205 fit with the scraper plate 102 in the scraper 11, thereby clamping the scraper plate 102 and driving the scraper 11 to slide.

[0037] Further options, such as Figure 6 As shown, the adjustment component includes an inner adjuster 206 and an adjustment limiter 207. The inner adjuster 206 is connected to the connecting plate 201, and the adjustment limiter 207 is connected to the pressure plate 202. The inner adjuster 206 is inserted into the adjustment limiter 207. Each of the two opposite side plates of the adjustment limiter 207 is provided with a vertically extending limit groove. Each of the two opposite side plates of the inner adjuster 206 is fixed with a limit ear at the bottom. The limit ear is inserted into the corresponding limit groove and can slide in the limit groove to adaptively adjust according to the height of the scraper plate 102.

[0038] In a preferred embodiment, a spring can be installed between the inner adjuster 206 and the adjustment limiter 207. The spring force can make the scraper plate 102 fit more firmly with the frame top plate 6.

[0039] The following provides a further explanation of the specific structure of the aforementioned connecting base.

[0040] like Figure 1 , Figure 2 , Figure 7 As shown, the connecting base 13 is the main hub, with a fixed adaptive adjustment device connected to one side and a fixed handle 14 connected to the other side. It is fixed to the bearing seat 31 by the central fixing plate 303 and slides along the guide rail 32 with the bearing seat 31.

[0041] like Figure 7 As shown, the connecting base 13 includes a central fixing plate 303, a limiting connecting plate 301, a center beam 302, and a fixing seat 304. The central fixing plate 303 overlaps the guide assembly 3, and the horizontal inner end of the central fixing plate is fixed to the bearing seat 31 in the guide assembly 3. The downwardly inclined outer end of the central fixing plate 303 is provided with a rectangular groove extending inward. The limiting connecting plate 301 is located between the central fixing plate 303 and the adaptive adjuster 12, and is connected to the adaptive adjuster 12. The positioning beam 302 passes through the rectangular groove and connects the fixed limiting connecting plate 301 and the central fixing plate 303. The rectangular groove and the positioning beam 302 form a V-shaped bevel. The positioning beam 302 continues to extend inward to the bottom of the central fixing plate 303, forming a triangular fixing structure. The fixing seat 304 is fixed to the horizontal inner end of the central fixing plate 303. The fixing seat 304 is provided with multiple threaded holes, which are connected to the elongated hole of the adjusting plate 401 of the handle 14. The bolt can slide up and down in the elongated hole to adjust the height of the handle 14 in real time.

[0042] The following is a further explanation of the specific structure of the handle described above.

[0043] like Figure 1 , Figure 2 , Figure 8 As shown, the handle 14 includes an adjustment plate 401, a pulley seat 403, a universal roller 402, and a handrail. The adjustment plate 401 is arranged in the inner ring of the grease baffle 4, and the upper part of the adjustment plate 401 is connected to the connecting base 13. The pulley seat 403 is arranged below the frame top plate 6 and fixed to the lower part of the adjustment plate 401. The universal roller 402 is installed on the top surface of the pulley seat 403 and fits against the bottom surface of the frame top plate 6, forming a rolling pair between the two. The handrail is fixed on the adjustment plate 401, and the connecting base 13 and the adaptive adjustment cleaning device can be moved by holding the handrail.

[0044] Further options, such as Figure 8As shown, the handrail includes a single handrail 405 and a two-way handrail 404. The single handrail 405 is fixed to the middle of the side of the adjusting plate 401, and a gap is left between the single handrail 405 and the side of the adjusting plate 401 to achieve side gripping. The two-way handrail 404 is arranged at the lower part of the adjusting plate 401 and is fixed together with the pulley seat 403 and the adjusting plate 401. A gap is left between the two-way handrail 404 and the side of the adjusting plate 401 and the bottom surface of the pulley seat 403 to achieve bottom and side gripping, adapting to different frame heights and personnel. The upper part of the adjusting plate 401 is provided with an elongated hole, which is connected to the connecting base 13 by bolts. After loosening the bolts, the height of the handle 14 can be adjusted through the elongated hole, thereby adjusting the universal roller 402 to fit against the bottom surface of the frame top plate 6.

[0045] Cleaning process: By pushing the universal handle 14 by hand, the bearing seat 31 slides on the slide rail 32. The bearing seat 31 drives the connecting base 13 to slide, and the connecting base 13 drives the grease scraper 11 to slide. The grease scraper 102 pushes the grease towards the drain hole, and the accumulated grease is discharged from the drain channel to the frame.

[0046] In summary, this invention provides a grease cleaning system for mining machinery, achieving the following functions and effects: The grease collection chamber is located below the rotary motor. It is an annular oil storage space formed by the frame rotary seat, the grease baffle and the frame top plate. It is used to collect and store the grease that drips from the upper rotary motor lubrication cover.

[0047] The adaptive adjustment cleaning device, including a grease scraper and an adaptive adjuster, is fixed to the guide assembly via a connecting base. The grease scraper is placed inside the grease collection chamber, occupying the entire chamber space laterally, and slides along a rail. Its scraping plate pushes the grease inside the chamber towards the drain hole, where it is discharged outside the frame through the drain channel. The adaptive adjuster is connected to the connecting base at the top, and clamps on both sides of the lower part of the adaptive adjuster hold the grease scraper in place, restricting its forward and backward movement. The adaptive adjuster achieves vertical self-adjustment in height via an internal adjuster and an adjustment limiter, accommodating grease scrapers of different heights.

[0048] The upper part of the handlebar is fixed to the guide assembly via a connecting base, while the lower part of the handlebar is placed in a universal caster to fit against the bottom of the frame top plate and slides along the rail. The bottom two-way handrail allows for bottom and side gripping, while the middle side single handrail allows for side gripping, accommodating different frame heights and riders. The handlebar height can be adjusted via an elongated hole on the adjustment plate.

[0049] The base is the main hub, with a fixed adaptive adjustment cleaning device connected to one side and a fixed handle connected to the other side. It is fixed to the slide rail bearing seat by the central fixing plate and slides along the slide rail with the bearing seat, thus driving the adaptive adjustment cleaning device to operate.

[0050] The guide assembly consists of a bearing housing and a guide rail. The guide rail is fixed to the upper end of the grease baffle. The adaptive adjustment cleaning device cleans the grease by sliding in an annular motion through the bearing housing.
