[0034] During the aluminum electrolysis process, the electrolyzed aluminum needs to be transported out by an overhead crane, which moves along a track. With the long-term use of the overhead crane, dust is easily accumulated on the tracks of the overhead crane, affecting the operation of the overhead crane, so dust removal is required frequently. Some related technologies use soot blowing for cleaning, however, the cleaning effect is not thorough, and manual cleaning is still required in some cases, which is inefficient and easily affects the safety of the operation.

[0035] In order to solve the above problems, an embodiment of the present application proposes an overhead travelling crane structure 100 .

[0036] Please refer to Figure 1 and Figure 2 The overhead crane structure 100 proposed in the embodiment of the present application includes a track 10, a car body 30 and a cleaning device 50. Among them, the track 10 includes a connecting beam 13 and at least two guide rails 11 arranged side by side, and the connecting beam 13 is connected to the at least two guide rails 11. The car body 30 is connected to the guide rail 11. Specifically, the car body 30 is provided with a running wheel 31, and the running wheel 31 can be driven to rotate so that the car body 30 moves along the extension direction of the guide rail 11 to perform operations such as transportation or loading and unloading. The cleaning device 50 includes an air outlet 51, which is connected to the car body 30 and has an air outlet 51a. It can be understood that the air outlet 51a is arranged below the car body 30, and the cleaning device 50 can blow out air through the air outlet 51a. In the embodiment of the present application, the air outlet 51a can swing relative to the car body 30 so that the air outlet 51a blows air at least toward the inner side of the connecting beam 13 and the guide rail 11.

[0037] For the convenience of description, the overhead crane structure 100 is defined as having a front-to-back direction XX, a left-to-right direction YY, and an up-to-down direction ZZ, wherein the front-to-back direction XX, the left-to-right direction YY, and the up-to-down direction ZZ are mutually perpendicular, and the guide rail 11 is extended along the front-to-back direction XX, the width direction of the vehicle body 30 is arranged along the left-to-right direction YY, and the height direction of the vehicle body 30 is extended along the up-to-down direction ZZ. It should be noted that, in some embodiments, the front-to-back direction XX and the left-to-right direction YY are both arranged horizontally, and the up-to-down direction ZZ is arranged along the vertical direction.

[0038] Exemplarily, the air outlet member 51 can rotate around an axis parallel to the up-down direction ZZ, and the air outlet 51a is arranged toward one side of the axis. During the rotation of the air outlet member 51, the direction of the air outlet 51a can swing between the connecting beam 13 and the guide rail 11, and the wind flowing out of the air outlet 51a blows toward the connecting beam 13 and the guide rail 11, thereby achieving the cleaning of the dust inside the connecting beam 13 and the guide rail 11. Of course, the air outlet member 51 can be swung around an axis along the front-to-back direction XX or the left-to-right direction YY. Furthermore, the air outlet member 51 can swing in two directions. The air outlet member 51 can swing around an axis parallel to the up-down direction ZZ, and can swing around an axis extending along the front-to-back direction XX, so that the air outlet member 51 is more flexible and can clean the track 10 at more angles.

[0039] In the embodiment of the present application, a cleaning device 50 is provided on the vehicle body 30, and the cleaning device 50 is provided with an air outlet 51, which can blow air to clean the track 10 with the movement of the vehicle body 30, so as to achieve a relatively large range of sweeping of the track 10. The air outlet 51 in the embodiment of the present application can swing relative to the vehicle body 30 to change the direction of the air outlet 51a, expand the sweeping range, and enable the air outlet 51 to sweep the track 10 at multiple angles, and can at least blow and clean the inner side of the guide rail 11, so that the cleaning is more thorough, thereby ensuring a good cleaning effect, reducing or avoiding manual cleaning, improving work efficiency and reducing safety hazards.

[0040] In the embodiment of the present application, the air outlet member 51 may be a blower and may be driven to swing as a whole. Alternatively, in one embodiment, the cleaning device 50 includes an air pump 55 and at least two air outlet members 51, the air pump 55 is connected to the vehicle body 30, and is connected to the at least two air outlet members 51 in a one-to-one correspondence through at least two air pipes. In this way, the air outlet of multiple air outlet members 51 can be easily controlled through a unified air pump 55, and the air outlet is stable with a higher air outlet pressure, the cleaning range is larger, and the cleaning effect is more thorough.

[0041] Please refer to Figure 2In one embodiment, the air outlet member 51 includes a fixed portion 511 and a swing portion 513. The fixed portion 511 is connected to the vehicle body 30. In this embodiment, the fixed portion 511 is arranged at the bottom of the vehicle body 30 and can be connected to the vehicle body 30 by screw connection or welding to improve stability and structural strength. The vehicle body 30 and the connecting beam 13 are arranged at intervals to form a purge gap. At least part of the swing portion 513 is located between the vehicle body 30 and the connecting beam 13, and penetrates into the purge gap to be able to blow air to the track 10 part at the bottom of the vehicle body 30. Among them, the swing portion 513 is movably connected to the fixed portion 511, so that the swing portion 513 can swing relative to the fixed portion 511, so that the air outlet 51a is arranged toward the guide rail 11 and / or the connecting beam 13. In this embodiment, by setting the fixed portion 511 at the bottom of the vehicle body 30, the air outlet member 51 is prevented from swinging in a large range, which is conducive to improving the swing stability.

[0042] In the embodiment of the present application, the swing part 513 can be extended and arranged obliquely toward the track 10 relative to the fixed part 511, so that the air outlet 51a can be arranged obliquely toward the connecting beam 13 or the guide rail 11, so as to be able to clean the larger connecting beam 13 part and the inner side of the guide rail 11. As shown in the figure, in some other embodiments, the swing part 513 is arranged in a tubular shape, one end of the swing part 513 is connected to the fixed part 511, and the other end extends away from the vehicle body 30 in the vertical direction (up and down direction ZZ). The air outlet 51a is arranged at one end of the swing part 513 away from the vehicle body 30, and the end of the swing part 513 away from the vehicle body 30 is bent so that the direction of the air outlet 51a is arranged at an angle with the vertical direction. By extending the swing part 513 in a direction away from the vehicle body 30, the air outlet 51a is as close to the track 10 as possible while occupying less space, thereby improving the cleaning effect. By setting the direction of the air outlet 51a at an angle to the vertical direction, the wind blown out of the air outlet 51a can be blown obliquely to a farther part of the surface of the track 10, and the sweeping range is larger.

[0043] In order to enable the air outlet member 51 to swing, the cleaning device further includes a swinging drive member 53. In one embodiment, the swinging drive member 53 is connected to the vehicle body 30, and the output end of the swinging drive member 53 is connected to the air outlet member 51, so as to at least drive the air outlet member 51 to swing along an axis perpendicular to the extension direction of the guide rail 11. In this embodiment, the guide rail 11 extends along the front-to-back direction XX, and the swinging drive member 53 can drive the air outlet member 51 to swing around an axis extending along the up-down direction ZZ, so that the air outlet 51a can sweep the inner side of the connecting beam 13 and the guide rail 11 from left to right or from right to left, thereby improving the cleaning effect.

[0044] Specifically, the swing drive component 53 can be connected to the fixed part 511 or directly connected to the vehicle body 30, which can be selected as a motor. The output end of the swing drive component 53 can be directly connected to the swing part 513. When the output end of the swing drive component 53 rotates, the swing part 513 rotates accordingly. The structure is simple and easy to implement.

[0045] Furthermore, if Figure 2 and Figure 3 As shown, for the convenience of structural arrangement, the swinging wind driving member 53 is connected to the air outlet member 51 by transmission. Exemplarily, the air outlet member 51, specifically the swinging wind part 513, is provided with a first gear 5131, and the swinging wind driving member 53 includes a driving source 531 and a transmission member 533, the driving source 531 can be selected as a motor, the driving source 531 is connected to the vehicle body 30, and is spaced apart from the air outlet member 51 for easy assembly. The output end of the driving source 531 is provided with a second gear 5311, and the transmission member 533 connects the output end of the driving source 531 and the air outlet member 51, which can be selected as a transmission belt or a transmission rod slidably connected to the vehicle body 30. The transmission member 533 is provided with a transmission tooth, and the transmission tooth is meshed and connected with the first gear 5131 and the second gear 5311, so as to drive the first gear 5131 to rotate when the second gear 5311 rotates, thereby causing the swinging wind part 513 to swing. This embodiment is transmitted by means of gear meshing, which is more accurate and controllable, and has high reliability. The swing drive member 53 and the air outlet member 51 can be arranged at intervals by transmission, thereby reducing the difficulty of assembly and structural arrangement.

[0046] Of course, in other embodiments of the present application, the swing drive member 53 may also be driven by other means such as a connecting rod mechanism, and the present application embodiment does not limit this. In addition, when the cleaning device 50 is provided with at least two air outlet members 51, the driving source 531 may be connected to the at least two air outlet members 51 by a transmission connection to synchronously drive the at least two air outlet members 51 to swing, thereby ensuring the movement synchronization of the at least two air outlet members 51 and reducing the material cost.

[0047] Please refer to Figure 2 In one embodiment, the cleaning device 50 is provided with at least two air outlets 51, and the at least two air outlets 51 are provided on both sides of the vehicle body 30. It can be understood that the at least two air outlets 51 can swing synchronously or asynchronously to clean the rails 10 in different areas. In this embodiment, by providing at least one air outlet 51 on both sides of the vehicle body 30, the at least two air outlets 51 can respectively sweep the rails 10 near the left and right sides of the vehicle body 30, so that the rails 10 on both sides can be cleaned more thoroughly to ensure the cleaning effect.

[0048] like Figure 4As shown, in one embodiment, the cleaning device 50 is provided with at least two air outlets 51, and the at least two air outlets 51 are provided on one side of the vehicle body 30, and the at least two air outlets 51 are provided at intervals along the extension direction of the guide rail 11. That is to say, at least two air outlets 51 can be provided on one side of the vehicle body 30 in the present application, and during the movement of the vehicle body 30, at least two air outlets 51 successively clean the track 10 part, so that the track 10 part on one side of the vehicle body 30 can be cleaned more thoroughly, further ensuring the cleaning effect, and can also effectively avoid repeated cleaning, thereby improving the cleaning efficiency.

[0049] It is understandable that the air outlets 51a of at least two air outlets 51 on one side of the vehicle body 30 can be oriented in the same direction and swing synchronously to ensure that the track 10 within the swing range can be thoroughly cleaned. In another embodiment, the air outlets 51a of at least two air outlets 51 are oriented at an angle. For example, when the air outlet 51a of one air outlet 51 is oriented toward the connecting beam 13, the air outlet 51a of the other air outlet 51 is oriented toward the inner side of the guide rail 11; or, when the air outlet 51a of one air outlet 51 is oriented toward the inner side of the guide rail 11, the air outlet 51a of the other air outlet 51 is oriented toward the outer side of the guide rail 11. In this way, by staggering the air outlets 51a of the two air outlets 51, during the movement of the vehicle body 30, at least two air outlets 51 can clean the track 10 at more angles, cover a larger sweeping range, and improve the cleaning effect.

[0050] At least two air outlet members 51 can be driven one by one through at least two swinging wind driving members 53, so that the start and stop and the rotation angle of any air outlet member 51 can be controlled individually to form a variety of cleaning modes and cleaning ranges. In another embodiment, at least two air outlet members 51 are transmission connected. Optionally, at least two air outlet members 51 can be transmission connected to the driving source 531 through the same transmission member 533, for example, the driving source 531 can synchronously drive at least two air outlet members 51 to move through a transmission belt; or the driving source 531 can be connected to one of the air outlet members 51, and the remaining air outlet members 51 are transmission connected to the air outlet member 51 connected to the driving source 531. In this way, by making at least two air outlet members 51 transmission connected, on the one hand, the synchronization of movement can be guaranteed, and on the other hand, while improving the cleaning effect, the number of swinging wind driving members 53 can be reduced, thereby reducing material costs.

[0051] The above is an explanation of the optional specific implementation of the overhead crane structure 100 in the embodiment of the present application. It can be understood that the operating system using the above-mentioned overhead crane structure 100 has at least all the beneficial effects brought by the technical solutions of all the above-mentioned embodiments because it adopts all the technical solutions of all the above-mentioned embodiments, which will not be repeated here one by one.
