Description

Technical Field

[0001] This utility model relates to the field of railway parts painting processing, specifically a suspended conveying device for railway parts painting. Background Technology

[0002] After production, railway parts need to be painted. To improve painting efficiency and reduce painting costs, railway parts are usually suspended on a suspended conveyor chain that runs through the painting area, so that multiple railway parts pass through the painting area in sequence for automatic painting. However, in actual use, it has been found that railway parts need to be manually suspended on the conveyor chain. Especially for heavy railway parts, the suspension operation is quite laborious and has a large workload. The efficiency of the operators after continuous suspension operation is greatly reduced, which affects the continuity of the railway parts painting process. Utility Model Content

[0003] The purpose of this utility model is to provide a suspended conveying device for painting railway parts. It can solve the technical problems of large workload and low efficiency when manually suspending railway parts. It uses a lifting platform to lift the railway parts to the suspension height, and the railway parts are not easy to rub against the lifting platform after suspension, which greatly improves the efficiency and convenience of railway parts suspension and reduces the difficulty and workload of manual operation.

[0004] To achieve the above objectives, this utility model employs the following technical solution: A suspended conveying device for painting railway parts includes a lifting platform and a painting area disposed below a support rail. The support rail is provided with multiple suspension parts, and a drive chain is provided below the support rail to drive the multiple suspension parts to move simultaneously along the support rail. The bottom of each suspension part is rotatably connected to a gear, and the bottom of the gear is provided with a hook. The painting area is provided with a toothed plate that meshes with the gear. The top of the lifting platform is slidably connected to a placement platform for carrying railway parts, and the railway parts are provided with a hanging ring that cooperates with the hook.

[0005] Furthermore, the top of the lifting platform is provided with multiple guide grooves, and the bottom of the placement platform is rotatably connected with multiple rollers, which are rolled within the guide grooves.

[0006] Furthermore, a pit is provided below the support rail, and the lifting platform is slidably connected to the pit in the vertical direction. A power component that drives the lifting platform to move vertically is provided in the pit. After the lifting platform is lowered, the top of the placement platform is at the same height as the top of the pit.

[0007] Furthermore, the sidewall of the pit is provided with multiple guide rings, and the bottom of the lifting platform is provided with multiple sliding rods, which are slidably connected inside the guide rings.

[0008] Furthermore, the power unit is a scissor lift.

[0009] Furthermore, the longitudinal section of the support track is I-shaped, and the two sides of the suspension part are in contact with the two sides of the I-shape respectively.

[0010] Furthermore, the two sides of the suspension are symmetrically connected to contact wheels, which make rolling contact with the two sides of the I-shaped part.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The structure of this utility model has multiple suspension parts that can move relative to the support rail on the support rail. The suspension parts move relative to the support rail by means of a drive chain, and a gear is rotatably connected to the bottom of the suspension part. The bottom of the gear is provided with a hook. The spraying area is provided with a toothed plate that meshes with the gear. When the drive chain drives the multiple suspension parts to move along the support rail, when they pass through the spraying area, the gear at the bottom of the suspension part meshes with the toothed plate, thereby driving the gear to rotate along the toothed plate. This causes the railway parts suspended at the bottom of the suspension parts to rotate and move forward in the spraying area, thereby performing a more uniform spraying operation on all parts of the railway parts, greatly improving the efficiency and uniformity of the spraying. 2. A lifting platform is installed below the support rail. When suspending railway parts, they are manually dragged onto the lifting platform. Then, the lifting platform is used to raise the railway parts to the suspension height. When the suspension part passes, the hook at the bottom of the suspension part is hooked onto the hanging ring of the railway parts. It is not necessary to manually lift the railway parts for suspension. Especially for heavy railway parts, this greatly improves the convenience of suspension operation, reduces the workload of suspension operation, ensures the efficiency of continuous suspension operation, and ensures the continuity of painting process. 3. A placement platform for carrying railway components is slidably connected to the lifting platform along the horizontal direction. In this structure, after the hook at the bottom of the suspension part is connected to the hanging ring on the railway component, the drive chain drives the railway component to move horizontally continuously. When the lifting platform does not descend in time, the placement platform carrying the railway component moves horizontally relative to the lifting platform until the lifting platform descends and the railway component separates from the placement platform. During this process, the railway component will not rub against the lifting platform when it is dragged by the drive chain, avoiding possible scratches and wear on the railway component and ensuring the integrity of the railway component during the suspension process.

Detailed Implementation

[0017] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0018] Reference Figure 1 and Figure 2This utility model describes a suspended conveying device for painting railway parts. The main structure includes a lifting platform 2 and a painting area 3 located below a support rail 1. The support rail 1 is fixed to the top of the workshop by welding or anchor bolts, providing support for the suspension of the railway parts 9 and guiding their movement. The lifting platform 2 is driven by any existing power structure for its up-and-down movement. A painting robot, as used in the prior art, is installed in the painting area 3 to perform painting processing on the passing railway parts 9. This part is not modified; specifically, a painting robot of model RDPT01 manufactured by Shenzhen Rongde Robotics Technology Co., Ltd. can be used. The specific structure is not described in detail here. Multiple suspension parts 4 are provided on the support rail 1. Part 4 is used to suspend railway accessories 9. Below the supporting rail 1, a drive chain 5 is provided to drive multiple suspension parts 4 to move simultaneously along the supporting rail 1. The drive chain 5 is driven by a motor, specifically a drive gear 6 is provided on the output shaft of the motor. The drive gear 6 meshes with the drive chain 5 to achieve continuous motion drive of the drive chain 5. The suspension parts 4 are fixed to the drive chain 5 by welding or bolts, enabling simultaneous movement drive of multiple suspension parts 4. The bottom of each suspension part 4 is rotatably connected to the gear 6 via a bearing. The bottom of the gear 6 is provided with a hook 7. Specifically, a fixing ring is fixed to the bottom of the gear 6 by welding or integral molding, and the hook 7 is suspended on the fixing ring. Within the spraying area 3, teeth that mesh with the gear 6 are fixed by welding or bolts. In this structure, when the drive chain 5 drives the suspension part 4 through the spraying area 3, the gear 6 on the suspension part 4 meshes with the gear plate 8, thereby driving the suspension part 4, which suspends the railway accessory 9, to rotate forward. This achieves more uniform spraying of the rotating railway accessory 9 at all positions, further improving the efficiency and uniformity of the painting process. The top of the lifting platform 2 is slidably connected to a placement platform 10 for supporting the railway accessory 9. The railway accessory 9 is fixed with a hanging ring 11, which works with the hook 7, by welding or integral molding. Before suspension, the lifting platform 2 is lowered to its lowest position, making it easy for the operator to drag the railway accessory 9 onto the placement platform 10 of the lifting platform 2. Then the lifting platform 2 rises, raising the railway accessory 9 to the suspension height. When the suspension part 4 passes by, the hook 7 at its bottom is attached to the hanging ring 11 of the railway accessory 9, realizing convenient suspension operation of the railway accessory 9. Especially for the heavy railway accessory 9, the suspension operation is more labor-saving, the workload of suspension is greatly reduced, and high efficiency can be maintained when the suspension operation is carried out continuously, ensuring the continuity of the painting process. After the railway accessory 9 is connected to the suspension part 4, if the lifting platform 2 does not descend in time, the drive chain 5 drags the railway accessory 9 to move, so that the placement platform 10 slides laterally relative to the lifting platform 2, thereby preventing the railway accessory 9 from being scratched and worn relative to the lifting platform 2. After the lifting platform 2 descends, the placement platform 10 is smoothly separated from the railway accessory 9, ensuring the integrity of the railway accessory 9 during the suspension process.

[0019] Preferably, the top of the lifting platform 2 is provided with multiple guide grooves 12, which are recessed downward from the top of the lifting platform 2. The bottom of the placement platform 10 is rotatably connected to multiple rollers 13 via bearings. The rollers 13 are rolled within the guide grooves 12. This structure makes the movement of the placement platform 10 relative to the lifting platform 2 a rolling motion, which reduces the friction between the two during relative movement and further improves the smoothness of their relative movement.

[0020] Preferably, a pit 14 is provided below the support rail 1, and the pit 14 is recessed from the workshop floor. The lifting platform 2 is vertically slidably connected to the pit 14, so that the lifting platform 2 can be lowered and hidden inside the pit 14. The pit 14 is provided with a power component that drives the lifting platform 2 to move vertically. The power component drives the lifting platform 2 to perform lifting and lowering movements. Specifically, a hydraulic cylinder or electric cylinder structure in the prior art can be used. After the lifting platform 2 is lowered, the top of the placement platform 10 is at the same height as the top of the pit 14. This structure ensures that when the lifting platform 2 is hidden inside the pit 14, the placement platform 10 and the ground at the top of the pit 14 remain flush. This allows the operator to easily drag the railway parts 9 onto the placement platform 10 without performing vertical lifting operations, greatly reducing the difficulty of suspension operations and improving the convenience of suspension operations.

[0021] Preferred, refer to Figure 4 Multiple guide rings 15 are fixed to the side wall of the pit 14 by welding or bolts, and multiple sliding rods 16 are fixed to the bottom of the lifting platform 2 by welding or bolts. The sliding rods 16 are slidably connected inside the guide rings 15. This structure allows the sliding rods 16 to slide vertically inside the guide rings 15 when the lifting platform 2 moves up and down, making it less likely for the lifting platform 2 to tilt during the lifting process. This further improves the stability of the railway parts 9 when the lifting platform 2 is lifted, avoids the slippage of the railway parts 9 when it is lifted, and ensures the smoothness and safety of the suspension operation.

[0022] Preferably, the power component is a scissor lift 17. The scissor lift 17 requires less vertical height after folding, which makes the pit 14 shallower, reduces the space occupied by the device, improves the convenience of device construction, and reduces construction costs.

[0023] Preferred, refer to Figure 3 The longitudinal section of the support track 1 is I-shaped. The two sides of the suspension part 4 are in contact with the two sides of the I-shaped part. The two sides of the I-shaped part can provide support for the suspension part 4 at the same time, making the suspension part 4 more stable when moving along the two sides of the I-shaped part, thus improving the stability of the suspension support for the railway component 9.

[0024] Preferably, the two sides of the suspension part 4 are symmetrically connected to contact wheels 18 via bearings. The contact wheels 18 make rolling contact with the two sides of the I-shaped part. This structure allows the suspension part 4 to make rolling contact with the two sides of the support rail 1 via the rollers 13 on both sides, thereby making the movement of the suspension part 4 relative to the support rail 1 smoother and the turning smoother, further improving the smoothness of the movement of the suspension part 4 along the support rail 1.

[0025] Working Principle: This invention features multiple movable suspension parts 4 on a support rail 1. Each suspension part 4 moves relative to the support rail 1 via a drive chain 5. A gear 6 is rotatably connected to the bottom of each suspension part 4, and a hook 7 is located at the bottom of the gear 6. A toothed plate 8 meshes with the gear 6 within the spraying area 3. When the drive chain 5 drives the multiple suspension parts 4 along the support rail 1, as they pass through the spraying area 3, the gear 6 at the bottom of the suspension part 4 meshes with the toothed plate 8, driving the gear 6 to rotate along the toothed plate 8. This causes the railway component 9 suspended at the bottom of the suspension part 4 to rotate and advance within the spraying area 3, resulting in more uniform spraying of the railway component 9 and significantly improving spraying efficiency and uniformity. A lifting platform 2 is located below the support rail 1. When the railway component 9 is suspended, it is manually dragged onto the lifting platform 2, and then the lifting platform 2 is used to raise the railway component 9 to the suspension height. As the suspension parts 4 pass, the bottom of the suspension part 4 is... The hook 7 is attached to the hanging ring 11 of the railway accessory 9, eliminating the need for manual lifting of the railway accessory 9 for suspension. This greatly improves the convenience of suspension operation, reduces the workload, and ensures the efficiency of continuous suspension operation, especially for heavier railway accessories 9, thus guaranteeing the continuity of painting processing. A placement platform 10 for supporting the railway accessory 9 is slidably connected to the lifting platform 2. With the hook 7 at the bottom of the suspension part 4 connected to the hanging ring 11 on the railway accessory 9, the drive chain 5 drives the railway accessory 9 to move continuously laterally. If the lifting platform 2 does not descend in time, the placement platform 10 supporting the railway accessory 9 moves laterally relative to the lifting platform 2 until the lifting platform 2 descends and the railway accessory 9 separates from the placement platform 10. During this process, the railway accessory 9 will not rub against the lifting platform 2 when it is dragged by the drive chain 5, avoiding possible scratches and wear on the railway accessory 9 and ensuring the integrity of the railway accessory 9 during suspension.
