Description

Technical Field

[0001] This utility model belongs to the field of gantry cranes, specifically a gantry crane that facilitates the cleaning of the slide rails. Background Technology

[0002] Gantry cranes, as an important logistics handling equipment, are widely used in various industrial settings, especially in places where material handling and operations need to be carried out over a large area. Through the horizontal movement and vertical lifting of goods, they greatly improve work efficiency and operational safety.

[0003] Traditional gantry cranes mainly consist of a metal frame, hoisting mechanism, traveling mechanism, and electrical control system. During operation, the hoisting mechanism is responsible for the vertical lifting and lowering of goods, while the traveling mechanism ensures that the crane can move smoothly on predetermined tracks. The crane, through the cooperation of slide rails and sliding lifting devices, moves goods from one place to another, achieving efficient logistics operations. However, in actual use, the working environment of gantry cranes is often quite harsh, which easily leads to the accumulation of dust and other impurities on the slide rails. These impurities increase the frictional resistance between the slide rails and the lifting device, thus affecting its operating efficiency. Traditional slide rail cleaning methods often require stopping the machine for manual cleaning, which is not only time-consuming and labor-intensive but also poses safety hazards, thus increasing the difficulty of slide rail cleaning.

[0004] In summary, this utility model provides a gantry crane that facilitates the cleaning of the slide rails, thereby solving the above-mentioned problems. Utility Model Content

[0022] Example 1

[0023] like Figure 1-4 As shown, this is the first embodiment of the present invention, which provides a gantry crane that facilitates cleaning of the slide rails, including...

[0024] The support mechanism 100 includes two support frames 110, a crossbeam 120 fixedly connected to the front and rear ends of the top of the support frame 110, and a slide rail 130 fixedly connected to the top of the crossbeam 120.

[0025] The lifting unit 200 includes a running component 210, a lifting component 220 disposed in the middle of the running component 210, and a cleaning component 230 disposed on the surface of the running component 210;

[0026] The running component 210 includes two connecting plates 211, a cover 212 fixedly connected to both ends of the connecting plates 211, pulleys 213 movably connected to both sides of the inner cavity of the cover 212 via bearings, and a first motor 214 fixedly connected to one side of the cover 212 and whose output shaft is drivenly connected to the pulley 213 on one side.

[0027] The cleaning assembly 230 includes a centrifugal fan 231, a splitter pipe 232 connected to the air outlets on both sides of the centrifugal fan 231 for splitting the airflow, a high-pressure nozzle 233 connected to the front and rear ends of one side of the splitter pipe 232 for blowing away dust and impurities on the surface of the slide rail 130, and a brush plate 234 fixedly connected to the bottom of the splitter pipe 232 for sweeping away dust and impurities on the surface of the slide rail 130.

[0028] like Figure 1-4 As shown, the support frame 110 and the cross frame 120 can provide stable support for the lifting unit 200, and the slide rail 130 can limit the movement of the running component 210. By integrating the cleaning component 230 with the running component 210 of the lifting unit 200, the slide rail 130 can be cleaned at the same time as the lifting operation, which improves the automation of the cleaning operation. When the centrifugal fan 231 is started, air is drawn in and the airflow is diverted to the high-pressure nozzle 233 through the diversion pipe 232. The high-pressure nozzle 233 sprays the airflow at high speed onto the surface of the slide rail 130, blowing away dust and other impurities. At the same time, the brush plate 234 brushes the surface of the slide rail 130 as the running component 210 moves, further removing impurities, thereby keeping the slide rail 130 clean, reducing frictional resistance, and improving the operating efficiency during lifting.

[0029] Example 2

[0030] Reference Figure 2 and 3 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0031] In this embodiment, the lifting assembly 220 includes a support plate 221, a second motor 222 fixedly connected to the bottom of the support plate 221, a winding roller 223 drivenly connected to the output shaft of the second motor 222, a wire rope 224 disposed on the surface of the winding roller 223, and a lifting device 225 disposed at one end of the wire rope 224. Both the second motor 222 and the first motor 214 are geared motors.

[0032] The bottom of the support plate 221 is fixedly connected to the top of the cover 212, and the bottom of the centrifugal fan 231 is fixedly connected to the top of the support plate 221. Limiting frames are fixedly connected to both sides of the bottom of the support plate 221. The winding roller 223 passes through the inner cavity of the limiting frame and is movably connected to the inner cavity of the limiting frame through a bearing.

[0033] like Figure 2 and 3As shown, the second motor 222 provides powerful force, which, through the transmission of the winding roller 223 and the wire rope 224, enables the lifting device 225 to stably lift and move the cargo, thereby improving work efficiency. The support plate 221, as the supporting structure of the lifting assembly 220, not only connects the second motor 222 and the winding roller 223, but also positions and supports the winding roller 223 through the limit frame, ensuring its stability and safety during operation.

[0034] Example 3

[0035] Reference Figure 1 and 2 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0036] In this embodiment, pulley 213 is located on the surface of slide rail 130 and is slidably connected to the surface of slide rail 130. One end of connecting plate 211 is fixedly connected to diverter pipe 232. The air inlet end of centrifugal fan 231 is connected to filter cartridge, and the inner cavity of filter cartridge is provided with interception net.

[0037] The bottom of the support frame 110 is movably connected to a caster wheel 111, and the surface of the caster wheel 111 is provided with a brake pad.

[0038] like Figure 1 and 2 As shown, the sliding connection between pulley 213 and slide rail 130 ensures that the running component 210 can move smoothly on slide rail 130. The fixing of connecting plate 211 and diverter pipe 232 ensures the stability of diverter pipe 232 during use. The design of caster wheel 111 and brake pad at the bottom of support frame 110 is intended to improve the mobility and stability of gantry crane, while ensuring that it can stop quickly and reliably when needed, so that it can move flexibly between different positions and adapt to different working environments.

[0039] In use, the support frame 110, in conjunction with the crossbeam 120, provides stable support for the lifting unit 200. When lifting operations are required, the first motor 214 is started, driving the pulley 213 to slide on the slide rail 130. This causes the running component 210 to move the lifting component 220 and the cleaning component 230 together along the slide rail 130 until the lifting component 220 reaches the desired position. Then, the lifting device 225 is used to lift the goods, and the second motor 222 is started, driving the winding roller 223 to rotate through the transmission mechanism, thereby winding up the goods. Alternatively, the wire rope 224 can be lowered to lift and raise the cargo. During the lifting operation, the cleaning component 230 starts working, the centrifugal fan 231 starts, draws in air and diverts the airflow to the high-pressure nozzle 233 through the diversion pipe 232. The high-pressure nozzle 233 sprays the airflow at high speed onto the surface of the slide rail 130, blowing away dust, oil and other impurities. At the same time, the brush plate 234 brushes the surface of the slide rail 130 as the running component 210 moves, further removing impurities, thereby keeping the slide rail 130 clean, reducing frictional resistance and improving the operating efficiency during lifting.
