Description

Technical Field

[0001] This utility model relates to the field of single-girder bridge crane technology, and in particular to a high-performance electric single-girder bridge crane. Background Technology

[0002] A high-performance electric single-girder bridge crane is a lifting device featuring an electric drive system and a single-girder structure. It achieves efficient material handling in industrial production through a bridge-rail system. This crane is compact in design, easy to operate, and suitable for environments with limited space. Its high performance refers to its strong load-bearing capacity, precise lifting control, and low energy consumption, enabling it to improve work efficiency while ensuring safety. It is widely used in warehouses, workshops, ports, and other similar locations.

[0003] In the existing technology for the design of single-girder cranes, such as the technical solution provided by Chinese utility model patent with publication number CN222410763U, existing electric single-girder bridge cranes lack track cleaning functions. During long-term operation, dust, oil stains or metal debris easily accumulate, leading to increased track friction resistance, aggravated wheel wear, and even problems such as slippage and rail jamming, affecting operational accuracy and safety.

[0004] Meanwhile, without a self-cleaning brush device, residual dirt from cleaning tools can secondary contaminate the tracks or reduce cleaning efficiency, increasing the frequency of manual maintenance and downtime, ultimately raising operating costs and shortening equipment lifespan. Therefore, we propose a high-performance electric single-girder bridge crane. Summary of the Invention

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a high-performance electric single-girder bridge crane to solve the technical problems that current cranes do not have track cleaning function and cannot clean cleaning tools.

[0006] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: A high-performance electric single-girder bridge crane is designed, comprising an I-beam, a U-shaped plate slidably connected to the lower part of the I-beam, spur gears rotatably connected to both sides of the U-shaped plate facing the I-beam, a rack fixedly connected to the upper part of the inner wall of the I-beam, with the spur gears meshing with the rack, a guide rail fixedly connected to the lower part of the I-beam, and a slider slidably connected to the guide rail fixedly connected to the inner side of the U-shaped plate; fixed boxes fixedly connected to both sides of the U-shaped plate, rotating rods rotatably connected to both sides of the fixed boxes, a brush fixedly connected to the first end of the rotating rod, and a rotating assembly inside the fixed box, which drives the rotating rods and spur gears when rotating; air cylinders fixedly connected to both ends of the top of the I-beam, and a moving assembly for driving two sets of air cylinders to move in the middle; and an air blowing assembly for blowing air onto the brush inside the air cylinder.

[0007] Preferably, the rotating assembly includes a motor fixedly connected to one side of one of the fixed boxes, a first bevel gear fixedly connected to the output end of the motor, a transmission shaft fixedly connected to the middle of the first bevel gear passing through the U-shaped plate and fixedly connected to the spur gear, and a second bevel gear located inside the fixed box and meshing with the first bevel gear fixedly connected to the opposite ends of the two rotating rods.

[0008] Preferably, the movable component includes a fixed plate, a connecting block is fixedly connected to the lower part of the fixed plate, a connecting rod is fixedly connected to the bottom of the connecting block, a sliding plate is fixedly connected to the bottom of the connecting rod, and a groove is provided on the top of the I-beam for sliding connection with the sliding plate.

[0009] Preferably, the air blowing assembly includes a slide rod that is slidably connected to the inside of the air cylinder, a piston is fixedly connected to one end of the slide rod, a telescopic spring is fixed to the periphery of the slide rod at one end of the air cylinder, and air blowing ports for blowing air onto the brush are provided on both sides of one end of the air cylinder.

[0010] Preferably, the bottom ends of the I-beam are fixedly connected to brackets.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model uses a starting motor to drive the rotation of a rotating component, which in turn drives the brush to rotate. Through the cooperation of the guide rail and slider, as well as the cooperation of the spur gear and rack, the U-shaped plate and hook lock move left and right. During the movement of the U-shaped plate, the rotating component drives the brush to rotate, thereby cleaning the surface of the track and rack, removing dust, debris and oil stains from the track, reducing frictional wear between the spur gear and rack, reducing running resistance, extending equipment life, preventing slippage or jamming, improving operational stability and safety, reducing maintenance frequency and downtime, and ensuring production efficiency.

[0013] 2. In this utility model, the movement of the U-shaped plate drives the left and right movement of the top fixed plate, which in turn drives the slide rod to apply pressure inside the air cylinder. When the cleaning brush reaches the left or right side, the air cylinder blows dust off the brush through the air nozzle. The U-shaped plate, in conjunction with the slide rod, applies pressure, and the air cylinder blowing function can automatically remove dust from the brush, maintain cleaning efficiency, reduce manual intervention, avoid clogging, extend brush life, and improve cleaning effect and system stability. It is suitable for high-frequency cleaning scenarios. Attached Figure Description

This invention achieves stable movement through the sliding connection between a U-shaped plate and an I-shaped steel section, as well as the meshing of gears and racks. The rotating components within the fixed box synchronously drive the brush and spur gear, ensuring synchronized cleaning and movement. Guide rails and sliders enhance operational stability. An air-blowing component automatically removes dust from the brush, reducing manual maintenance. The overall design features efficient linkage, improving track cleaning effectiveness, extending equipment lifespan, and is suitable for automated cleaning scenarios.

[0024] Specifically, the rotating assembly includes a motor 6 fixedly connected to one side of one of the fixed boxes 3, a first bevel gear 7 fixedly connected to the output end of the motor 6, a transmission shaft 11 fixedly connected to the middle of the first bevel gear 7 passing through the U-shaped plate 2 and fixedly connected to the spur gear 12, and a second bevel gear 8 located inside the fixed box 3 and meshing with the first bevel gear 7, fixedly connected to the opposite ends of the two rotating rods 9. This invention uses a motor to drive the first bevel gear, which synchronously drives the spur gear and the track to move via the transmission shaft. Simultaneously, the first bevel gear meshes with the second bevel gear to drive the brush to rotate, achieving integrated movement and cleaning. The structure is compact, the transmission is efficient, reducing additional power sources and lowering energy consumption; the gear meshing ensures precise and synchronized movements, improving cleaning efficiency, while simplifying maintenance, making it suitable for automated track cleaning systems.

[0025] Furthermore, the moving component includes a fixed plate 13, a connecting block 17 fixedly connected to the lower part of the fixed plate 13, a connecting rod 16 fixedly connected to the bottom of the connecting block 17, and a sliding plate 18 fixedly connected to the bottom of the connecting rod 16. A groove 19 is provided on the top of the I-beam 1, which slides smoothly along the groove on the top of the I-beam 1. This invention, through the linkage design of the fixed plate, connecting block, and sliding plate, allows the air cylinder to move smoothly along the groove on the top of the I-beam. The structure is simple and reliable, the sliding is smooth, ensuring that the air blowing component accurately aligns with the brush for cleaning, improving automation, reducing manual intervention, and enhancing overall cleaning efficiency.

[0026] It is worth noting that the air blowing assembly includes a slide rod 15 that is slidably connected to the inside of the air cylinder 14. A piston 21 is fixedly connected to one end of the slide rod 15, and a telescopic spring 22 fixed to the periphery of the slide rod 15 is provided at one end of the air cylinder 14. Air blowing ports 20 for blowing air onto the brush 10 are provided on both sides of one end of the air cylinder 14. This utility model uses the slide rod to drive the piston to compress the telescopic spring, and uses the air pressure difference to automatically spray air from the air blowing port, effectively removing dust accumulated on the brush. The structure is simple and reliable, the spring return ensures continuous operation, no additional power is required, it is energy-saving and environmentally friendly, significantly improves the cleaning effect and reduces the maintenance frequency.

[0027] It is worth mentioning that both ends of the bottom of the I-beam 1 are fixedly connected to brackets 23. The brackets 23 enhance the stability and load-bearing capacity of the I-beam 1, ensuring that the overall structure is solid and reliable.

[0028] Working principle: In use, the motor 6 drives the first bevel gear 7, which in turn drives the spur gear 12 to move along the internal rack of the I-beam 1 via the transmission shaft 11. Simultaneously, the first bevel gear 7 meshes with the second bevel gear 8, causing the brush 10 to rotate and clean the track. The moving component drives the sliding plate 18 to move along the slide groove 19. When the brush 10 reaches its limit position, the slide rod 15 compresses the spring 22, triggering the air cylinder 14 to blow air, automatically removing the dust accumulated on the brush. The entire system achieves fully automated linkage of movement, cleaning, and dust removal, resulting in high efficiency and energy saving.
