A multi-functional cantilever crane

Abstract

This utility model relates to the technical field of cantilever cranes, and in particular to a multi-functional cantilever crane, comprising: a frame body one with a plate body one fixedly connected to its side; a slide rail fixedly connected to the top of the plate body one; a plate body two fixedly connected to one side of the frame body; an adjustment mechanism one disposed on the plate body one; and a frame body two disposed on the adjustment mechanism one. By adjusting the mechanism one, the aluminum alloy workpiece can be rotated 45 or 60 degrees to discharge the residual chemicals. Compared with the vertical lifting of a gantry crane, this reduces the residual time and amount of chemicals on the workpiece. Moreover, the movement path and direction of the workpiece during lifting are relatively flexible, allowing the workpiece to be lifted out of the tank at a more suitable angle and trajectory, so that the chemicals can drip back into the original tank more smoothly. This avoids the situation where chemicals may flow disorderly due to the swinging of the workpiece during the lifting process of a gantry crane, causing them to drip into other tanks or the ground and cause pollution.

Description

Technical Field

[0001] This utility model relates to the technical field of cantilever cranes, and in particular to a multifunctional cantilever crane. Background Technology

[0002] Aluminum alloy anodizing is an electrochemical surface treatment process that involves applying current to an aluminum alloy as the anode in an acidic electrolyte, forming a dense alumina film on its surface to improve the material's corrosion resistance, wear resistance, insulation, and aesthetics. During processing, the aluminum alloy is placed in an electrolyte (such as sulfuric acid or oxalic acid) as the anode. Upon the application of current, an oxidation reaction occurs, where aluminum atoms combine with the released oxygen to form an alumina (Al₂O₃) film. The cathode, typically made of inert materials such as lead, is primarily responsible for conductivity. The growth of the oxide film is dynamically balanced with the chemical dissolution in the electrolyte; initially, the film thickness increases rapidly, then stabilizes due to increased resistance, ultimately forming a porous honeycomb structure.

[0003] Currently, the production of aluminum alloy anodizing in the market includes the following key stages:

[0004] Preparation: Clean the aluminum alloy surface to remove oil and impurities, ensuring a smooth and clean surface.

[0005] Electrolytic oxidation: An aluminum alloy is immersed in an electrolyte solution, with direct current or alternating current applied as the anode. The voltage (typically 5–25V), temperature (below 25°C), and electrolysis time are controlled to form an oxide film. The film thickness can reach 10–200μm.

[0006] Dyeing: Utilizing the porosity of the oxide film, colors (such as black, gold, etc.) are added through electrolytic coloring.

[0007] Sealing treatment: Use hot water or chemical agents to seal the pores, thereby enhancing the corrosion resistance and insulation of the film.

[0008] When immersing the aluminum alloy in the electrolyte, a cantilever crane is required. Related technologies involve installing a crossbar on a gantry crane, with a telescopic structure and mounting frame at the bottom of the crossbar. The telescopic structure changes the angle of the mounting frame, and the gantry crane changes the height of the crossbar. This allows the mounting frame to be horizontal during processing, with the aluminum alloy workpiece submerged in the electrolyte. Conversely, raising the crossbar and extending the telescopic structure tilts the aluminum alloy workpiece, causing it to rise from the electrolyte for easy drainage of residual liquid. However, in practical use, the angle adjustment range is limited, resulting in low drainage efficiency. If residual chemicals in the aluminum alloy workpiece cannot be drained in time, cross-contamination can occur during the next step, causing inconvenience. Furthermore, the structure is complex and makes it difficult to clean residual chemicals from the crane, thus presenting certain limitations. Utility Model Content

[0012] Optionally, the aluminum alloy workpiece is connected to the mounting bracket via a clamp.

[0013] Optionally, the adjustment mechanism includes: a housing slidably connected to the plate; a motor fixedly connected to one side of the housing; a guide wheel rotatably connected to the inside of the housing, and the output end of the motor is fixedly connected to the guide wheel, the guide wheel being inserted into the slide rail; and the frame is fixedly connected to the housing.

[0014] Optionally, the motor and the guide wheel are a set, and multiple sets are provided on the housing.

[0015] Optionally, the second adjustment mechanism includes: a second motor fixedly connected to the second frame; a first take-up roller rotatably connected to one side of the second frame; a steering mechanism disposed on one side of the second frame, the output end of the second motor being connected to one end of the first take-up roller via the steering mechanism, and one end of the connecting belt being wound around the outside of the first take-up roller.

[0016] Optionally, a fixing plate is fixedly connected to two sides of the frame, a motor is fixedly connected to the fixing plate, a take-up roller is rotatably connected to the top of the fixing plate, the output end of the motor is connected to one end of the take-up roller through a right-angle deflector, a sliding groove is provided on the inner side of the frame, a guide wheel is provided on the mounting block, the guide wheel is slidably connected to the sliding groove, the top of the mounting block is connected to the take-up roller through a connecting belt, and one end of the connecting belt is wound on the take-up roller.

[0017] Optionally, the second guide wheel is rotatably connected to the mounting block.

[0018] Optionally, the first connecting belt and the second connecting belt are belts.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. Adjusting the position of frame two via adjustment mechanism one simultaneously moves the aluminum alloy workpiece back and forth. Then, activating adjustment mechanism two causes the aluminum alloy workpiece to rotate clockwise until it is submerged in the chemical solution for oxidation treatment. Conversely, by driving adjustment mechanism two to rotate the aluminum alloy workpiece 45 or 60 degrees, the residual chemical solution can be discharged. Compared to vertical lifting by a gantry crane, this method reduces the residual time and amount of chemical solution on the workpiece. Furthermore, the movement path and direction during workpiece lifting are relatively flexible, allowing the workpiece to be lifted from the tank at a more suitable angle and trajectory, enabling the chemical solution to drip back into the original tank more smoothly. This avoids the situation where, during gantry crane lifting, the chemical solution may flow disorderly due to workpiece swaying, causing it to drip into other tanks or the ground and cause pollution.

[0021] 2. The working area covered by this application is relatively small and more targeted, unlike gantry cranes which may need to move over a large area above multiple different functional tanks. This makes the hoisting operations above each tank relatively independent, reducing the risk of chemicals splashing from one tank to another during hoisting and effectively reducing cross-contamination between different chemicals. Furthermore, the cantilever tilting crane causes relatively little disturbance to the surrounding air during operation. Due to its larger structure, a gantry crane may cause significant airflow during operation, leading to fluctuations or even splashing of chemicals on the surface of the tank. In contrast, the air disturbance generated by the cantilever tilting crane is minimal, thus reducing the possibility of chemical droplets splashing into other tanks and causing contamination due to airflow.

[0022] 3. Compared to gantry cranes, cantilever tilting cranes have a simpler structure, lacking the complex crossbeams and trolley traveling mechanisms of gantry cranes. This makes cleaning residual chemicals adhering to the crane easier, allowing for timely removal of any potentially carried residual chemicals and further reducing the risk of contaminating chemicals in other tanks. Due to the relatively smaller structure of the cantilever tilting crane, local protective devices can be more easily installed, such as drip trays or protective curtains installed under the cantilever. These protective facilities effectively catch dripping chemicals during lifting, preventing them from scattering and reducing contamination of the surrounding environment and chemicals in other tanks.

[0034] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use, or the orientation or positional relationship commonly understood by those skilled in the art. They are only used to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0035] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0036] In current technology, a horizontal bar is installed on a gantry crane, with a telescopic structure and mounting frame at the bottom. The angle of the mounting frame is changed by the telescopic structure, and the height of the horizontal bar is changed by the gantry crane. This allows the mounting frame to be horizontal during processing, with the aluminum alloy workpiece on the mounting frame submerged in the bath. Conversely, when the horizontal bar is raised, the telescopic structure extends, causing the aluminum alloy workpiece to tilt and rise from the bath, facilitating the drainage of residual liquid from the inside of the aluminum alloy. However, in actual use, the angle adjustment range is small, resulting in low drainage efficiency. If the residual chemicals in the aluminum alloy workpiece cannot be drained in time, cross-contamination can occur when proceeding to the next step, causing inconvenience in practical use. Furthermore, the structure is relatively complex and inconvenient for cleaning residual chemicals on the crane, thus having certain limitations.

[0037] like Figure 1-4 As shown, this utility model embodiment provides a multi-functional cantilever crane, including: a frame 10 with a plate 11 fixedly connected to its side; a slide rail 12 fixedly connected to the top of the plate 11; a plate 13 fixedly connected to one side of the frame 10; an adjustment mechanism 20 disposed on the plate 11; a frame 21 disposed on the adjustment mechanism 20, the adjustment mechanism 20 being used to adjust the front and rear positions of the frame 21; and a mounting block 22 disposed on the inner side of the frame 21. A horizontal plate 23 is rotatably connected to the side of the mounting block 22; a connecting strap 24 is disposed on the top of the horizontal plate 23; an adjustment mechanism 25 is mounted on the frame 10, and the other end of the connecting strap 24 is connected to the adjustment mechanism 25. The adjustment mechanism 25 and the connecting strap 24 are used to adjust the angle of the horizontal plate 23; a limiting plate 26 is fixedly connected to the bottom of the horizontal plate 23; a mounting bracket 27 is inserted into the limiting plate 26; and an aluminum alloy workpiece 28 is disposed on the mounting bracket 27.

[0038] The aluminum alloy workpiece 28 to be processed is clamped onto the mounting frame 27 using a fixture. Then, the mounting frame 27 is inserted into the limiting plate 26 via a plug-in connection, thus installing the aluminum alloy workpiece 28. Next, the first adjustment mechanism 20 is activated to adjust the position of the second frame 21. As the second frame 21 moves back and forth, it also moves the horizontal plate 23, the limiting plate 26, and the aluminum alloy workpiece 28 back and forth until the aluminum alloy workpiece 28 is positioned directly above the designated chemical tank. At this point, the horizontal plate 23 is tilted. The second adjustment mechanism 25 is then activated, allowing the connecting belt 24 to unwind from the second adjustment mechanism 25. Simultaneously, the aluminum alloy workpiece 28, through the mounting frame 27, the limiting plate 26, and the horizontal plate 23, rotates clockwise under its own weight. Pull the connecting belt 24 to keep it taut until the horizontal plate 23 rotates to a horizontal position. The aluminum alloy workpiece 28 is then immersed in the chemical solution for oxidation treatment. Next, the adjusting mechanism 25 is driven again to rotate the aluminum alloy workpiece 28 counterclockwise until it reaches 45 or 60 degrees. The adjusting mechanism 25 is then closed, and the remaining chemical solution in the aluminum alloy workpiece 28 flows out from its side and falls back into the chemical tank. The adjusting mechanism 20 is then driven to slide on the slide rail 12, adjusting the front and rear position of the frame 21 again. This moves the aluminum alloy workpiece 28 to the next chemical tank, and the above steps are repeated for another immersion treatment. (Direction reference) Figure 1 ).

[0039] Furthermore, the aluminum alloy workpiece 28 is connected to the mounting frame 27 via a clamp, which facilitates the installation and disassembly of the aluminum alloy workpiece 28. The clamp is a spring clamp or a lead screw clamp.

[0040] Furthermore, the adjustment mechanism 20 includes: a housing 201 slidably connected to the plate 11; a motor 202 fixedly connected to one side of the housing 201; a guide wheel 203 rotatably connected to the inside of the housing 201, and the output end of the motor 202 is fixedly connected to the guide wheel 203, the guide wheel 203 is inserted into the slide rail 12, and the frame 21 is fixedly connected to the housing 201.

[0041] When motor 202 is turned on, its output end drives guide wheel 203 to rotate inside housing 201. Then, through the contact between guide wheel 203 and slide rail 12, guide wheel 203 slides back and forth along slide rail 12, thereby causing housing 201 to slide back and forth, thus adjusting the position of frame 21 (direction reference). Figure 1 ).

[0042] Furthermore, the motor 202 and the guide wheel 203 are a set, and multiple sets are provided on the housing 201, so that multiple guide wheels 203 work at the same time, so that the housing 201 is subjected to uniform force, thereby making its sliding more stable.

[0043] Furthermore, the second adjustment mechanism 25 includes: a second motor 251 fixedly connected to the second frame 21; a first take-up roller 253 rotatably connected to one side of the second frame 21; a steering device 252 disposed on one side of the second frame 21, the output end of the second motor 251 being connected to one end of the first take-up roller 253 via the steering device 252, and one end of the connecting belt 24 being wound around the outside of the first take-up roller 253.

[0044] When motor 251 is turned on, its output end drives take-up roller 253 to rotate through steering gear 252, and then the connecting belt 24 is wound around take-up roller 253, thereby pulling the cross plate 23 to rotate on the mounting block 22, so as to adjust the angle of the cross plate 23 and the aluminum alloy workpiece 28.

[0045] Furthermore, a fixing plate 30 is fixedly connected to the side of the frame 21, a motor 31 is fixedly connected to the fixing plate 30, and a take-up roller 32 is rotatably connected to the top of the fixing plate 30. The output end of the motor 31 is connected to one end of the take-up roller 32 through a right-angle deflector. A sliding groove 33 is provided on the inner side of the frame 21, and a guide wheel 34 is provided on the mounting block 22. The guide wheel 34 is slidably connected to the sliding groove 33. The top end of the mounting block 22 is connected to the take-up roller 32 through a connecting belt 35, and one end of the connecting belt 35 is wound on the take-up roller 32.

[0046] When the initial height of the horizontal plate 23 needs to be adjusted, the motor 31 is turned on, and its output end drives the take-up roller 32 to rotate on the fixed plate 30. At the same time, the connecting belt 35 is wound around the outside of the take-up roller 32, and the mounting block 22 and the guide wheel 34 are pulled to slide in the slide groove 33. Then, the mounting block 22 drives the horizontal plate 23 to move upward, thereby adjusting the height of one end of the horizontal plate 23. Then, by turning on the adjustment mechanism 25, the height of the other end of the horizontal plate 23 is adjusted, thereby adjusting the overall height of the horizontal plate 23. This method is suitable for soaking aluminum alloy workpieces 28 of different heights.

[0047] Furthermore, the second guide wheel 34 is rotatably connected to the mounting block 22, so that the water flow causes the second guide wheel 34 to slide upward in the groove 33, and the second guide wheel 34 to rotate in the mounting block 22, reducing friction and making the up-and-down sliding of the mounting block 22 more stable.

[0048] Furthermore, the connecting belt 24 and the connecting belt 35 are belts, and the angle and height of the cross plate 23 can be adjusted by winding and unwinding the belts.

[0049] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
