Description

Technical Field

[0001] This utility model relates to the field of transfer vehicle technology, specifically to an RGV vehicle for transferring wires used in surface treatment. Background Technology

[0002] In industries such as metal processing and wire and cable manufacturing, surface treatment of wires, such as galvanizing, spraying, and heat treatment, are key processes for ensuring product quality. The efficiency of wire transfer between these processes directly affects the smoothness of the overall production flow and the final product quality. Currently, the industry relies heavily on manual handling or simple mechanical equipment for wire transfer, which has many shortcomings that make it difficult to adapt to the demands of modern production.

[0003] The primary problem with manual handling or using simple mechanical equipment is low transfer efficiency. Limited by the speed and physical strength of manual operation, it's difficult to match the rhythm of continuous production line operation. Furthermore, during handling, wires are prone to slipping and collisions, potentially causing injuries to operators and resulting in scratches and deformation on the wire surface, damaging its original state and affecting subsequent surface treatment results. Moreover, surface treatment workshops, due to the nature of the processes, are generally filled with corrosive gases, have high temperatures, and are contaminated with dust. Long-term work in this environment, even with protective equipment, can easily lead to occupational health problems such as respiratory discomfort and skin irritation.

[0004] To address this, a wire transfer RGV vehicle for surface treatment is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a wire transfer RGV vehicle for surface treatment to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wire transfer RGV vehicle for surface treatment, comprising a main body of a hanging rail, the main body of the hanging rail being a long strip-shaped steel structure, the top of which is fixedly connected to a pre-set load-bearing beam or bracket in the workshop, a trolley of the hanging rail being mounted on the main body of the hanging rail, a frame being mounted on the bottom of the trolley of the hanging rail, and a base frame being mounted on the bottom of the frame.

[0007] The base frame has guide rails symmetrically installed on both sides of its bottom. A lifting frame is slidably connected to the guide rails. A hook for suspending cables is installed in the middle of the lifting frame. A lifting mechanism for controlling the up and down movement of the lifting frame is installed inside the frame.

[0008] Preferably, the lifting frame has two pulleys symmetrically rotatably connected, and the outer ring of the two pulleys is provided with an arc-shaped groove adapted to the steel wire rope.

[0009] Preferably, the lifting mechanism includes a spool installed inside the frame; two sets of steel wire ropes are symmetrically wound around the outside of the spool, and circular limiting plates are provided at both ends of the spool to prevent the steel wire ropes from falling off. The diameter of the circular limiting plates is larger than the diameter of the spool, and the two sets of steel wire ropes are respectively wound around the outside of two pulleys.

[0010] Preferably, the lifting mechanism further includes a drive motor and a wire clamp; the drive motor is installed on the outside of the frame, and the output shaft of the drive motor is connected to one end of the wire drum through a reducer. The reducer is a gear reducer or a worm gear reducer, the input end of which is connected to the output shaft of the drive motor, and the output end is connected to the end of the wire drum.

[0011] Preferably, the wire clamp is a U-shaped metal clamp, which is installed on the lower surface of the frame and is fixedly connected to one end of the wire rope.

[0012] Preferably, the hook is equipped with an anti-detachment protrusion to prevent the wire from falling off. The anti-detachment protrusion is integrally cast or welded to the hook and is installed at the opening of the hook.

[0013] Preferably, the frame of the overhead rail trolley is made of high-strength, corrosion-resistant material, such as 1.4652 alloy, 725LN stainless steel, or 3J01 elastic alloy.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the mechanized transfer mode of using a trolley and lifting mechanism greatly improves the efficiency of wire transfer, reduces labor costs, and avoids manual operation in the corrosive gas, high temperature and dust environment of the surface treatment workshop, reducing occupational health risks such as respiratory diseases and skin burns, and eliminating the need to rely on complex manual protective equipment.

[0015] The hook opening is equipped with an anti-slip protrusion, which can effectively prevent the wire from slipping off the hook during transportation, avoiding damage to the wire or safety accidents. The lifting mechanism is driven by symmetrical steel wire ropes, pulleys and reducers to ensure that the lifting frame is evenly stressed and the lifting is smooth, preventing the wire from tilting and bumping, ensuring the integrity of the wire surface and not affecting the quality of subsequent surface treatment processes such as galvanizing and spraying.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a wire transfer RGV vehicle for surface treatment, including a hanging rail body 1. The hanging rail body 1 is a long strip-shaped steel structure, and its top is fixedly connected to a pre-set load-bearing beam or bracket in the workshop, serving as the basic load-bearing structure of the entire RGV vehicle to stably fix the entire equipment in the workshop space. A hanging rail trolley 2 is installed on the hanging rail body 1. The hanging rail trolley 2 can move along the extension direction of the hanging rail body 1 to realize the horizontal position adjustment of the entire transfer structure, providing a horizontal movement foundation for wire transfer. A frame 3 is installed at the bottom of the hanging rail trolley 2, and the frame 3 is fixedly connected to the hanging rail trolley 2, providing a supporting carrier for the subsequently installed base frame 5 and lifting mechanism 4.

[0023] A base frame 5 is installed at the bottom of frame 3. Guide rails 6 are symmetrically installed on both sides of the bottom of base frame 5 to guide the movement of lifting frame 7. Lifting frame 7 is slidably connected to guide rails 6, and can slide up and down along the vertical direction of guide rails 6 to adjust its height. A hook 9 for suspending cables is installed in the middle of lifting frame 7, used to hang cables and bear the weight of the cables. A lifting mechanism 4 is installed inside frame 3 to control the up and down movement of lifting frame 7. Lifting mechanism 4 cooperates with lifting frame 7, driving lifting frame 7 to slide along guide rails 6 through its own movement, thereby adjusting the height of the cables suspended on hook 9.

[0024] like Figure 1 and Figure 2 As shown: Two pulleys 8 are symmetrically rotatably connected to the lifting frame 7. Each pulley 8 is connected to the lifting frame 7 via a rotating shaft, and their symmetrical arrangement ensures balanced force distribution. The outer ring of each pulley 8 has an arc-shaped groove adapted to accommodate the wire rope. This groove matches the shape of the wire rope, accommodating it and preventing it from detaching from the pulleys 8 during transmission. Simultaneously, the rotation of the pulleys 8 converts the sliding friction of the wire rope into rolling friction, reducing wear and improving transmission efficiency.

[0025] like Figure 1 and Figure 2As shown: The lifting mechanism 4 includes a spool 41; both ends of the spool 41 are provided with circular limiting plates to prevent the wire rope from falling off. The circular limiting plates are fixedly connected to the spool 41 and limit the wire rope wound around the outside of the spool 41, preventing the wire rope from slipping off the end of the spool 41 during winding or release. Two sets of wire ropes are symmetrically wound around the outside of the spool 41. One end of each set of wire ropes is fixedly connected to the spool 41, and the other end is wound around the outside of two pulleys 8 respectively. The pulleys 8 change the direction of force on the wire ropes, so that the two sets of wire ropes can apply tension or thrust to the lifting frame 7 simultaneously, ensuring the force balance of the lifting frame 7 during the lifting process and preventing the lifting frame 7 from tilting.

[0026] like Figure 1 and Figure 2 As shown: The lifting mechanism 4 also includes a drive motor 42 and a wire clamp 43; the drive motor 42 is installed on the outside of the frame 3 and provides power output to the lifting mechanism 4. The output shaft of the drive motor 42 is connected to one end of the wire drum 41 through a reducer. The reducer is a gear reducer or a worm gear reducer. Its input end is connected to the output shaft of the drive motor 42 to receive the power output by the drive motor 42, and its output end is connected to the end of the wire drum 41 to transmit the power after reduction and torque amplification to the wire drum 41, driving the wire drum 41 to rotate stably and ensuring the smoothness of wire rope winding and release.

[0027] like Figure 2 As shown: The wire clamp 43 is a U-shaped metal clamping component with good structural strength. The wire clamp 43 is installed on the lower surface of the frame 3. The wire clamp 43 is fixedly connected to one end of the wire rope, and fixes the position of one end of the wire rope through clamping action. This allows the wire rope to be adjusted in length with the wire clamp 43 as the fixed end when it rotates with the spool 41, thereby stably pulling or pushing the lifting frame 7 to move.

[0028] like Figure 3 As shown: The hook 9 is equipped with an anti-detachment protrusion 91 to prevent the wire from slipping off. The anti-detachment protrusion 91 and the hook 9 are integrally cast or welded together. The anti-detachment protrusion 91 is installed at the opening of the hook 9, forming a blocking structure at the opening of the hook 9. When the wire is hooked on the hook 9, it can prevent the wire from slipping off the opening of the hook 9, thus improving the safety of the wire during transportation.

[0029] like Figure 1As shown, the frame of the overhead trolley 2 is made of high-strength, corrosion-resistant material, specifically 1.4652 alloy, 725LN stainless steel, or 3J01 elastic alloy. This frame, as the core load-bearing component of the overhead trolley 2, must support the total weight of the frame 3, base frame 5, lifting mechanism 4, and wiring. The high-strength material ensures that the frame is not easily deformed or damaged during load-bearing. Furthermore, the surface treatment workshop may contain corrosive environments; the corrosion-resistant material effectively enhances the frame's corrosion resistance, extends the service life of the overhead trolley 2, and ensures its long-term stable operation.

[0030] Working principle: The main body 1 of the lifting rail is pre-fixed on the workshop's load-bearing beam or bracket, serving as the fixed load-bearing foundation for the entire equipment. When the transfer position needs to be adjusted, the lifting rail trolley 2 moves along the extension direction of the main body 1, simultaneously driving the connected frame 3, base frame 5, and subsequent components to move as a whole until the hook 9 moves directly above the wire to be transferred, completing the horizontal position calibration.

[0031] Start the drive motor 42, which drives the spool 41 to rotate. Since one end of the wire rope is clamped and fixed by the wire clamp 43, the rotation of the spool 41 releases the two sets of wire ropes wound on it. The wire ropes move along the outside of the pulley 8, causing the lifting frame 7 to slide vertically down along the guide rails 6 on both sides of the base frame 5. This causes the hook 9 in the middle of the lifting frame 7 to descend synchronously until the hook 9 reaches the location of the wire to be transferred. After the wire is hooked onto the hook 9, the drive motor 42 switches its rotation direction, and the spool 41 begins to wind the two sets of wire ropes. During the winding process, the wire ropes apply an upward pulling force to the lifting frame 7, causing the lifting frame 7 to slide vertically up along the guide rails 6. The hook 9 rises synchronously with the wire. During this process, the anti-detachment protrusion 91 on the hook 9 prevents the wire from slipping off the opening of the hook 9, ensuring the stability of the wire hoisting.

[0032] After the wire is raised to a safe height, the trolley 2 moves along the main body 1 again to transfer the wire to the target position required for the surface treatment process.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
