Description

Technical Field

[0001] This application relates to conveying equipment, and more particularly to an overhead crane device. Background Technology

[0002] In the anodizing process, workpieces need to be placed sequentially into different anodizing tanks to achieve cleaning, oxidation, and coloring. Currently, the transfer of workpieces between different anodizing tanks is mostly achieved using an overhead crane. Multiple workpieces are first mounted on a fixture, which is then suspended on an overhead crane. The crane slides along a track, thus positioning the workpieces in different anodizing tanks. During the anodizing process, the heated reagents produce corrosive gases, and in this environment, the track is easily corroded and damaged. Utility Model Content

[0003] In view of this, this application provides a crane device that helps prevent track corrosion.

[0004] This application provides a crane device, including a track, a crane, a jetting device, and a protective gas supply device. The crane is slidably mounted on the track for movement along the track. The jetting device is installed on the track and is used to spray protective gas around the track. The protective gas supply device is connected to the jetting device and is used to supply protective gas to the jetting device.

[0005] In the overhead crane device of this application, the protective gas ejected by the jetting device blows away the corrosive gas located around the track, which helps to prevent the corrosive gas from contacting the track, thereby preventing the track from being corroded and giving the overhead crane device a better anti-corrosion effect; and the track can be in the protective gas environment output by the protective gas supply device, which helps to enhance the protective effect of the track.

[0006] In some possible implementations, the track includes a bearing surface and a mounting surface, which are arranged opposite to each other along the length of the track. The overhead crane is mounted on the bearing surface, and the jetting device is mounted on the mounting surface. Positioning the jetting device on the mounting surface helps prevent it from obstructing the crane's movement; furthermore, the jetting device, located below the track and the oxidation tank, allows the protective gas emitted by the jetting device to quickly blow the corrosive gases generated by heating in the oxidation tank away from the track, thus enhancing the protective effect.

[0007] In some possible implementations, there are multiple jet devices, which are evenly spaced along the length of the track on the mounting surface. This helps the jet devices to blow away corrosive gases flowing to various locations on the track, thereby enhancing the protective effect.

[0008] In some possible implementations, the overhead crane device includes a gas sensor and a controller, the controller being connected to the gas sensor, an air jet device, and a protective gas supply device; when the gas sensor detects that the concentration of corrosive gas reaches a preset value, the controller controls the air jet device to eject air; when the gas sensor detects that the concentration of corrosive gas is lower than the preset value, the controller controls the air jet device to reduce the airflow rate; when the gas sensor detects that the concentration of corrosive gas is higher than the preset value, the controller controls the air jet device to increase the airflow rate, or the controller controls the protective gas supply device to output protective gas to the air jet device and controls the air jet device to eject the protective gas output by the protective gas supply device at the maximum airflow rate.

[0009] In some possible implementations, the gas sensor is positioned on the bearing surface. With the gas sensor positioned above the guide rail, the corrosive gases generated by heating in the oxidation tank below the guide rail are blocked from flowing directly to the gas sensor, which helps improve the gas sensor's accuracy in sensing the concentration of corrosive gases around the guide rail.

[0010] In some possible implementations, the bearing surface is provided with a groove that extends along the length of the track, and the overhead crane is slidably disposed in the groove.

[0011] In some possible implementations, the overhead crane is equipped with rollers, and the overhead crane is slidably positioned in a groove via the rollers.

[0012] In some possible implementations, the jetting device includes a blower and a jet hood, with the blower disposed inside the jet hood.

[0013] In some possible implementations, the surface of the track is provided with a lubricating layer. This lubricating layer helps reduce wear on the track and also prevents corrosive gases from contacting the track, thus preventing corrosion.

[0014] In some possible implementations, the overhead crane assembly includes an air pipe, through which a protective gas supply device is connected to a jetting device. Attached Figure Description

When a component is considered to be "located" on another component, it can be directly located on the other component or may also have an intervening component.

[0021] It is worth noting that when there is an "electrical connection" between two components or parts, electrical conduction can be achieved through methods such as direct contact, welding, or adhesive bonding. The term "and / or" includes any and all combinations of one or more of the related listed items.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.

[0023] Some embodiments of this application will now be described with reference to the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0024] Please see Figure 1 and Figure 2 This application provides a crane device 1, which can be applied in anodizing processes. The crane device 1 includes a crane 10, a track 20, and a jetting device 30. The crane 10 is slidably mounted on the track 20 to move along it. The jetting device 30 is installed on the track 20 and sprays protective gas around the track 20 to blow away corrosive gases, thus preventing corrosive gases from contacting the track 20 and preventing corrosion. The protective gas sprayed by the jetting device 30 can be air, inert gas, etc. In this embodiment, there are two tracks 20 arranged in parallel, and the crane 10 is mounted on both tracks 20.

[0025] Please see Figure 4 In some embodiments, the jet device 30 includes a blower 32 disposed on the surface of the track 20, the blower 32 being used to generate airflow. It is understood that the jet device 30 may utilize other airflow generating devices, such as a vacuum pump.

[0026] Please see Figure 4 In some embodiments, the jetting device 30 includes a jet shroud 31 disposed on the surface of the track 20, and a blower 32 disposed inside the jet shroud 31. The jet shroud 31 is used to protect the blower 32. The jet shroud 31 has a through-hole 311 communicating between the interior and exterior of the jet shroud 31. The shape of the jet shroud 31 can be hemispherical. It can be understood that by adjusting the size and shape of the jet shroud 31 and the arrangement of the through-hole 311 on the jet shroud 31, the jetting device 30 can spray protective gas toward the lower, left, right and / or upper sides of the track 20.

[0027] Please see Figure 1 and Figure 2 Each track 20 includes a bearing surface 21 and a mounting surface 22. The bearing surface 21 and the mounting surface 22 are arranged opposite to each other along the length of the track 20. The overhead crane 10 is mounted on the bearing surface 21. The jetting device 30 is mounted on the mounting surface 22. The jetting device 30 is mounted on the mounting surface 22, which helps to prevent the jetting device 30 from obstructing the movement of the overhead crane 10; and since the jetting device 30 mounted on the mounting surface 22 is located below the track 20, and the oxidation tank is also located below the track 20, the protective gas ejected by the jetting device 30 can quickly blow away the corrosive gas generated by heating in the oxidation tank from the track 20, which helps to enhance the protective effect. Each track 20 also includes two first side surfaces 23 and two second side surfaces 24. The two first side surfaces 23 are arranged opposite to each other along the length of the track 20, and the two second side surfaces 24 are arranged opposite to each other along the width of the track 20. In another embodiment, the jetting device 30 can be mounted on the two second side surfaces 24.

[0028] Please see Figure 2 The number of jet devices 30 is multiple, and the multiple jet devices 30 are evenly spaced along the length of the track 10 on the mounting surface 22. The multiple jet devices 30 evenly spaced are beneficial to blowing away corrosive gases flowing to various positions of the track 20, thereby enhancing the protective effect.

[0029] Please see Figure 1 and Figure 2 The bearing surface 21 is provided with a groove 211. The groove 211 is recessed from the bearing surface 21 toward the rail 20. The groove 211 extends along the length of the rail 20. The overhead crane 10 is slidably disposed in the groove 211 and protrudes from the bearing surface 21.

[0030] Please see Figure 2The overhead crane 10 is equipped with rollers 11, which slide within the grooves 211. In this embodiment, the overhead crane 10 has two rollers 11, each housed in a groove 211 of one of the two tracks 20. In another embodiment, the overhead crane 10 may have multiple rollers 11, arranged in two groups on both sides of the overhead crane 10, with each group of rollers 11 housed in a groove 211.

[0031] In some embodiments, the groove 211 extends through both first side surfaces 23 to facilitate the assembly of the roller 11 with the groove 211.

[0032] In some embodiments, the groove 211 is provided with blocking members (not shown) at both ends of the track 20 along its length, the blocking members being used to prevent the roller 11 from sliding out of the groove 211.

[0033] Please see Figure 1 and Figure 2 The overhead crane device 1 includes a protective gas supply device 40, which is connected to a jetting device 30 via a gas pipe 50. The protective gas supply device 40 supplies protective gas to the jetting device 30. This protective gas can be ejected through the jetting device 30 to blow away corrosive gases surrounding the track 20, thus placing the track 20 in a protective gas environment and enhancing its protective effect. In this embodiment, the protective gas supply device 40 supplies inert gas to the jetting device 30.

[0034] In this embodiment, each jet device 30 installed on each track 20 is equipped with two protective gas supply devices 40. The two protective gas supply devices 40 are located on opposite sides of the track 20 in its length direction. One jet device 30 is connected to a portion of the jet devices 30 installed on one track 20 through a pipe 50, and the other jet device 30 is connected to another portion of the jet devices 30 installed on the same track 20 through another pipe 50.

[0035] In some embodiments, the air tube 50 can be fixed to the mounting surface 22 of the track 20, which helps to prevent the air tube 50 from getting tangled.

[0036] Please see Figure 1 and Figure 2The overhead crane device 1 includes a gas sensor 60, which is installed on the track 20 and used to detect the concentration of corrosive gas. When the gas sensor 60 detects that the concentration of corrosive gas reaches a preset value, the jetting device 30 is activated and the protective gas supply device 40 is deactivated. The air ejected by the jetting device 30 blows away the corrosive gas around the track 20. The preset value can be the concentration of corrosive gas at which corrosion may occur in a corrosive gas environment. When the concentration of corrosive gas is lower than the preset value, the track 20 is less likely to be corroded by the corrosive gas. When the gas sensor 60 detects that the concentration of corrosive gas is lower than the preset value, the airflow rate of the jetting device 30 can be reduced, or the jetting device 30 can be turned off. When the gas sensor 60 detects that the concentration of corrosive gas is higher than the preset value, the airflow rate of the jetting device 30 can be increased. When the air ejected by the jet device 30 reaches its maximum flow rate, the protective gas supply device 40 can be activated simultaneously, causing the jet device 30 to eject the protective gas (such as inert gas) output by the protective gas supply device 40. In other words, the jet device 30 can eject the protective gas output by the protective gas supply device 40 at its maximum flow rate.

[0037] In this embodiment, the gas sensor 60 is disposed on the bearing surface 21 of the guide rail 20. The gas sensor 60, located on the bearing surface 21, is situated above the guide rail 20. Corrosive gases generated during heating in the oxidation tank below the guide rail 20 are blocked by the guide rail 20 and do not flow directly to the gas sensor 60, which helps improve the accuracy of the gas sensor 60 in sensing the concentration of corrosive gases around the guide rail 20. In other embodiments, the gas sensor 60 may be disposed on the mounting surface 22, the first side surface 23, and / or the second side surface 24.

[0038] In this embodiment, there are four gas sensors 60, with two gas sensors 60 provided on each guide rail 20, located at opposite ends of the guide rail 20. In other embodiments, the number of gas sensors 60 may be one, two, three, or more than four, and this application does not impose any limitations.

[0039] Please see Figure 3The overhead crane device 1 includes a controller 70, which is connected to a gas sensor 60, an air jet device 30, and a protective gas supply device 40. The controller 70 receives sensing information from the gas sensor 60 and controls the activation of the air jet device 30 and the protective gas supply device 40. The controller 70 also controls the air jet device 30 to regulate the flow rate of the protective gas. When the gas sensor 60 detects that the concentration of corrosive gas reaches a preset value, the controller 70 activates the air jet device 30 and deactivates the protective gas supply device 40, causing the air jet from the air jet device 30 to blow away the corrosive gas around the track 20. When the gas sensor 60 detects that the concentration of corrosive gas is lower than the preset value, the controller 70 controls the air jet device 30 to reduce the flow rate of the air jet or shuts it off. When the gas sensor 60 detects that the concentration of corrosive gas is higher than the preset value, the controller 70 controls the jet device 30 to increase the flow rate of the ejected air, or controls the protective gas supply device 40 to start to deliver protective gas to the jet device 30 and controls the jet device 30 to eject the protective gas delivered by the jet device 30 at the maximum airflow rate.

[0040] In some embodiments, a lubricating layer is provided on the surface of the track 20. The lubricating layer covers the bearing surface 21, the mounting surface 22, the first side surface 23, the second side surface 24, and the groove wall of the groove 211; that is, the lubricating layer 21 covers the entire track 20. The lubricating layer can be applied to the surface of the track 20 by means of adhesion or coating. The lubricating layer can be a lubricating oil film or the like. Providing a lubricating layer helps reduce wear on the track 20 from the roller 11, and the lubricating layer also prevents corrosive gases from contacting the track 20, thus preventing corrosion of the track 20.

[0041] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and modifications made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
