Description

A bridge crane with a metal dust cleaning device Technical Field

[0001] This utility model relates to the field of metal dust cleaning technology, and in particular to a bridge crane with a metal dust cleaning device. Background Technology

[0002] In industries such as metallurgy and casting, bridge cranes operate in high-dust environments for extended periods. The accumulation of metal dust, in particular, not only affects the stability of equipment operation but can also lead to safety hazards such as short circuits and accelerated track wear. Currently, conventional bridge cranes primarily handle metal dust through periodic manual cleaning or simple negative pressure dust collection devices. However, existing technologies have significant shortcomings: manual cleaning is inefficient and carries high risks due to working at heights, while traditional dust collection devices often suffer from insufficient power or improper layout, making it difficult to thoroughly remove accumulated dust from critical components such as tracks, contact lines, and electrical cabinets. Furthermore, they cannot achieve real-time cleaning during operation. These technical deficiencies cause metal dust to continuously affect the equipment's conductivity, accelerate the wear of mechanical parts, and increase the risk of fire and explosion. Therefore, there is an urgent need to develop an integrated, efficient, automated metal dust cleaning system that can adapt to complex working conditions.

[0003] Existing technologies, such as the Chinese utility model patent with publication number CN202421159754.7, only allow cleaning of one side of the conductor rail, failing to clean the guide rail itself or perform lubrication maintenance during the cleaning process. During construction, due to equipment structural limitations, only unidirectional cleaning of the conductor rail surface is possible, making comprehensive cleaning of the guide rail impossible. Furthermore, existing technologies cannot simultaneously lubricate and maintain the guide rail during cleaning, resulting in the guide rail remaining in a state of dry friction for extended periods, accelerating component wear. Therefore, we propose a bridge crane with a metal dust cleaning device. Summary of the Invention

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a bridge crane with a metal dust cleaning device to solve the technical problems that can only clean one side of the sliding contact line, cannot clean the slide rail, and cannot achieve lubrication and maintenance during the cleaning process.

[0031] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0032] A bridge crane with a metal dust cleaning device includes a slide rail 3, a mobile device 2 slidably fitted around the periphery of the slide rail 3, a lifting device 1 slidably fitted at the top of the mobile device 2, a first motor 201 mounted on one side of the mobile device 2, the output end of the first motor 201 passing through the mobile device 2 and connected to a roller, a rotating wheel 7 mounted on one side of one end of the mobile device 2, the rotating wheel 7 cooperating with the roller, a connecting rod 701 provided on one side of the rotating wheel 7, and cleaning components provided at both ends of the mobile device 2, the cleaning components cooperating with the periphery of the slide rail 3; the cleaning components include a U-shaped frame 4 mounted at the end of the mobile device 2. A fixing block 702 is installed on one side of the U-shaped frame 4. A sliding rod 704 is slidably fitted inside the fixing block 702. One end of the sliding rod 704 is connected to one end of the connecting rod 701, and the other end of the sliding rod 704 is fitted with a T-shaped connecting rod 703. A sliding block 8 is slidably fitted on one side of the U-shaped frame 4. One end of the sliding block 8 is slidably fitted with the T-shaped connecting rod 703, and the other end of the sliding block 8 is fitted with a brush 801. A through groove is formed on the upper and lower sides of one end of the U-shaped frame 4. An oil tank 9 is installed in the through groove. A push rod 903 is installed on one side of the sliding block 8. One end of the push rod 903 passes through the oil tank 9 and is fitted with a compression device. Block 902, oil tank 9 has multiple nozzles 901 on one side facing the slide rail 3, and oil is sprayed out from the nozzles 901 by making the extrusion block 902 slide in the oil tank 9; one end of the U-shaped frame 4 has a cavity near the mobile device 2, the cavity is a dust collection box 10, a dust collection component is provided on one side of the dust collection box 10, and a feeding component 6 is provided between the dust collection box 10 and the dust collection component; the beneficial effect of this utility model is that by optimizing and improving the metal dust cleaning device of the bridge crane, a cleaning mechanism is added to the end of the mobile device 2, and the roller is rotated by the drive motor 201, which not only realizes the cleaning of the metal dust of the bridge crane, but also improves the cleaning of the metal dust of the bridge crane. The sliding block 8 moves and, through the linkage of the rotating wheel 7, connecting rod 701, and sliding rod 704, drives the brush 801 to clean the slide rail 3. At the same time, the dust collection component uses negative pressure to adsorb the cleaned metal dust and transports it to the unloading component 6 for centralized processing, effectively avoiding secondary dust pollution. In addition, the reciprocating motion of the sliding block 8 also drives the extrusion block 902 to slide in the oil tank 9 through the push rod 903, evenly spraying lubricating oil onto the surface of the slide rail 3, realizing simultaneous cleaning and lubrication, ensuring the rust prevention ability and smooth operation of the slide rail, and extending the service life of the equipment. This design integrates cleaning, lubrication, and collection functions.

[0033] Specifically, a plurality of sliding contact lines 301 are installed on one side of the slide rail 3, and the dust collection component slides and engages with the periphery of the sliding contact line 301 through the U-shaped frame 4; through the direct contact between the dust collection component and the sliding contact line 301, this utility model can effectively remove dust, oil and metal debris accumulated on the surface of the sliding contact line 301 while cleaning the slide rail 3, effectively avoiding the risk of poor conductivity or short circuit.

[0034] Furthermore, the dust collection component includes a frame 5 mounted on one side of the mobile device 2. A fan 501 is fixedly connected inside the frame 5. The air intake of the fan 501 is equipped with a pipe 502. One end of the pipe 502 extends through one end of the U-shaped frame 4 and cooperates with a cavity opened inside the U-shaped frame 4. A suction nozzle 1001 that cooperates with the periphery of the sliding contact line 301 is installed on one side of the cavity inside the U-shaped frame 4. A material discharge component 6 is provided at part of the pipe 502. Through the negative pressure suction generated by the fan 501, combined with the synergistic effect of the pipe 502 and the dust collection box 10, metal dust generated when the brush 801 cleans the slide rail 3 can be collected, reducing the accumulation of metal dust and its impact on equipment operation. At the same time, the suction nozzle 1001 can also clean the sliding contact line 301 simultaneously, keeping the conductive contact surface clean.

[0035] It is worth noting that a filter screen 503 is installed inside the pipe 502, and an electric push rod 504 is installed on one side of the pipe 502. The output end of the electric push rod 504 passes through one side of the pipe 502 and squeezes and cooperates with one side of the filter screen 503, causing the filter screen 503 to vibrate. A hopper 505 is installed on the other side of the pipe 502, corresponding to one side of the filter screen 503. A feeding component 6 is installed on one side of the U-shaped frame 4, and the feeding component 6 and the feeding hopper 505 are raised and lowered in cooperation. The beneficial effects of this utility model are: by installing a filter screen 503 inside the pipe 502, metal dust can be effectively intercepted and allowed to enter the feeding hopper 505 for centralized collection under negative pressure. At the same time, the electric push rod 504 can periodically push the filter screen 503 to vibrate, thereby reducing the accumulation of metal dust on the surface of the filter screen, preventing blockage, and reducing the frequency of manual cleaning.

[0036] It is worth mentioning that the unloading component 6 includes an L-shaped plate 601 fixedly connected to one side of the U-shaped frame 4. Two winding shafts 602 are rotatably connected between the L-shaped plate 601 and the U-shaped frame 4. Lifting ropes are wound around the periphery of each winding shaft 602, and the other end of each rope is connected to the unloading hopper 505. One end of each winding shaft 602 passes through one side of the L-shaped plate 601. A second motor 604 is installed at one end of one winding shaft 602, and a transmission gear 603 is installed at the end of each winding shaft 602. The gears 603 mesh with each other; this utility model sets up two synchronously linked winding shafts 602. After the metal dust is collected, the second motor 604 is started to drive one of the winding shafts 602 to rotate. The meshing transmission gears 603 drive the other winding shaft 602 to rotate synchronously, so that the lifting rope is lowered smoothly, thereby controlling the hopper 505 to descend slowly and realize the discharge of metal dust. This reduces tilting or jamming caused by unilateral force. Moreover, the double winding shaft design enhances the load-bearing capacity and safely unloads metal dust.

[0037] It is worth noting that the sliding block 8 is slidably fitted in the groove 802 opened on one side of the U-shaped frame 4. One end of the sliding block 8 extends out of the U-shaped frame 4 and is located between the T-shaped connecting rod 703 and the oil tank 9. The other end of the sliding block 8 located in the U-shaped frame 4 is concave. A brush 801 is installed on one side of the concave block. The brush 801 is slidably fitted with one side of the slide rail 3. By limiting the sliding block 8 to slide back and forth in the groove 802, the movement trajectory of the brush 801 is ensured to be stable, thereby cleaning the surface of the slide rail 3 evenly and avoiding cleaning dead corners.

[0038] It is worth noting that the extrusion block 902 is a half-extrusion block connected to one side of the sliding block 8 via the push rod 903. The extrusion block 902 and the push rod 903 are slidably fitted in the oil tank 9. An oil outlet is provided on one side of the oil tank 9, and an oil hopper 904 is provided on the side of the oil outlet. This utility model uses the reciprocating motion of the sliding block 8 to drive the extrusion block 902 to slide synchronously in the oil tank 9. The movement of the extrusion block 902 creates pressure changes inside the oil tank, thereby evenly spraying the lubricating oil through the nozzle 901 onto the surface of the slide rail 3. This synchronously sprays the lubricating oil during cleaning and avoids the problem of uneven application by manual application.

[0039] Working Principle: When using this utility model, the drive motor 201 is first started, and its rotation drives the roller to rotate. On the one hand, it drives the entire mobile device 2 to move, and on the other hand, it drives the rotating wheel 7 and the connecting rod 701 to rotate. The connecting rod 701 drives the sliding rod 704 to reciprocate within the fixed block 702. The sliding rod 704, through the T-shaped connecting rod 703, links the sliding block 8 to slide within the slide groove 802 of the U-shaped frame 4, driving the brush 801 to clean the slide rail 3. Simultaneously, the sliding block 8, through the push rod 903, drives the extrusion block 902 to reciprocate within the oil tank 9. The resulting hydraulic pressure propels the lubricating oil through the nozzle. 901 is evenly sprayed onto the slide rail 3, while the lower oil hopper 904 provides an oil replenishment channel for the oil tank. During the cleaning process, the vacuum cleaner, through the negative pressure generated by the fan 5, causes the metal dust swept by the brush 801 to enter the dust collection box 10 through the pipe 502. At the same time, the suction nozzle 1001 can also clean the sliding contact line 301 synchronously. After being intercepted by the filter screen 503, the dust falls into the discharge hopper 505. The electric push rod 504 periodically vibrates the filter screen to prevent clogging. Finally, the second motor 604, through the transmission gear 603, links the double winding shaft 602 to release the hanging rope, causing the discharge hopper 505 to descend and complete the dust discharge, realizing cleaning-lubrication-collection.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
