Description

Technical Field

[0001] This utility model relates to the field of workpiece conveying technology, and in particular to a steel component painting conveying device. Background Technology

[0002] Steel components such as crane beams, H-beams, T-beams, cross-shaped steel columns, angle steel, tie rods, box beams, channel steel, and roof steel beams, after fabrication, need to be transferred to the painting process for corrosion protection and decoration. This painting process uses a continuous conveyor system. The parts reaching the painting position are quickly painted by spray guns, ensuring a complete coating of the outer surface without any blind spots. Currently, the conveyor systems used in this painting process are mainly suspended conveyors and roller conveyors. Suspended conveyors suspend steel components by chains, driving the chains along tracks to continuously transport the components. While this type of conveyor has a strong load-bearing capacity, its stability is relatively poor due to the non-rigid nature of the chain, which affects the uniformity and quality of the paint application. Roller conveyors utilize continuously rolling conveyor rollers to transport steel components. While offering good conveying stability and high load-bearing capacity, they involve significant contact with the bottom of the steel components, which is detrimental to the protection of freshly painted surfaces. Furthermore, they are unsuitable for conveying irregularly shaped steel components such as crane beams, tie rods, and box girders. Therefore, a conveyor system with high load-bearing capacity, good stability, beneficial paint protection, and good versatility is needed to improve upon these limitations. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a steel component painting conveying device with strong load-bearing capacity, good stability, good paint protection and good versatility.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a steel component painting conveying device, including a conveying frame, on which a front sprocket assembly and a rear sprocket assembly are installed. Two parallel conveying traction chains are installed on the front sprocket assembly and the rear sprocket assembly. Several bearing rods are fixedly installed between the two conveying traction chains. Each bearing rod includes a bearing base plate that is fixedly connected to the corresponding chain links on the two conveying traction chains. A bearing upright plate that is higher than the conveying surface of the conveying traction chain is fixedly provided in the middle of the bearing base plate. The top of the bearing upright plate is used to support the steel component. Chain support structures are respectively provided on the conveying frame at the upper section of the conveying traction chain.

[0005] As a preferred technical solution, the front sprocket assembly includes two front sprocket bearing seats fixedly mounted on the conveyor frame, and a front sprocket shaft is rotatably mounted on both front sprocket bearing seats. The front sprocket shaft is fixedly provided with front conveyor sprockets for mounting the two conveyor traction chains respectively.

[0006] As a preferred technical solution, the front sprocket shaft is connected to a conveyor drive.

[0007] As a preferred technical solution, the rear sprocket assembly includes a rear sprocket shaft fixedly mounted on the conveyor frame, and rear conveyor sprockets for mounting the two conveyor traction chains are rotatably mounted on the rear sprocket shaft; a chain tensioner is provided between the rear sprocket shaft and the conveyor frame.

[0008] As a preferred technical solution, two rear sprocket mounting plates are fixedly provided on the conveyor frame, and the two rear sprocket mounting plates are respectively provided with rear sprocket mounting grooves, the groove openings of the rear sprocket mounting grooves facing away from the front sprocket assembly; the rear sprocket shaft is provided with anti-rotation limiting surfaces that abut against the two groove edges of the rear sprocket mounting grooves, and axial limiting bosses are respectively provided on the rear sprocket shaft on the side of the anti-rotation limiting surfaces.

[0009] As a preferred technical solution, the chain tensioner includes a chain tensioning seat fixedly disposed at the groove of the rear sprocket mounting slot, a tensioning bolt being installed through the chain tensioning seat, a tensioning screw hole being provided on the rear sprocket shaft, and the corresponding end of the tensioning bolt being threadedly connected to the tensioning screw hole.

[0010] Due to the adoption of the above technical solution, the steel component painting conveying device includes a conveying frame, on which a front sprocket assembly and a rear sprocket assembly are installed. Two parallel conveying traction chains are jointly installed on the front and rear sprocket assemblies, and several bearing rods are fixedly installed between the two conveying traction chains. Each bearing rod includes a bearing base plate fixedly connected to corresponding chain links on the two conveying traction chains. A bearing upright plate, higher than the conveying surface of the conveying traction chains, is fixedly provided in the middle of the bearing base plate, and the top of the bearing upright plate is used to support the steel component. Chain support structures are respectively provided on the conveying frame at the upper section of the conveying traction chains. This utility model uses fixed-point contact between the bearing rods and the steel components for conveying, and the bearing rods adopt an inverted T-shaped structure, which has strong load-bearing capacity, good stability, and a small contact area with the steel components, which is beneficial for paint protection. Because there is no mutual displacement between the steel components and the bearing rods, the conveying process is not affected by protruding structures on the steel components, thus it can be used for various conventional and irregularly shaped steel components, exhibiting good versatility.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0020] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the steel component painting conveying device includes a conveyor frame 1, which serves as the mounting carrier for various functional components. Its specific structure can be derived by those skilled in the art using conventional techniques and will not be elaborated upon here. A front sprocket assembly 2 and a rear sprocket assembly 3 are mounted on the conveyor frame 1. Two parallel conveying traction chains 4 are mounted on both the front and rear sprocket assemblies 2 and 3. Several bearing rods 5 are fixedly installed between the two conveying traction chains 4. Each bearing rod 5 includes a bearing base plate 51 fixedly connected to corresponding chain links on the two conveying traction chains 4. A bearing upright plate 52, higher than the conveying surface of the conveying traction chains 4, is fixedly provided in the middle of the bearing base plate 51. The top of the bearing upright plate 52 is used to support the steel component 9. Chain support structures 41 are respectively provided on the conveyor frame 1 at the upper section of the conveying traction chains 4.

[0021] The chain support structure 41 supports the upper section of the conveying traction chain 4, giving the bearing members 5 rigid support capabilities. The bearing members 5 are inverted T-shaped, simple in structure, and have high rigidity, thus collectively achieving strong load-bearing capacity and good stability in this embodiment. The bearing members 5 are arranged on the same set of conveying traction chains 4, ensuring that the bearing members 5 run at a consistent speed. Therefore, each bearing member 5 under load maintains contact with the fixed points on the steel component 9, preventing relative displacement between them. Furthermore, the bearing members 5 utilize the top of the bearing upright plate 52 for support contact, resulting in a small contact area that is beneficial for paint protection. The small volume and small contact area of ​​the bearing members 5 make it easy to avoid the influence of protruding structures on the steel component 9, thus adapting to various conventional and irregularly shaped steel components 9 for support, demonstrating good versatility.

[0022] Among them, such as Figure 1 As shown, the front sprocket assembly 2 includes two front sprocket bearing seats 21 fixedly mounted on the conveyor frame 1. A front sprocket shaft 22 is rotatably mounted on both front sprocket bearing seats 21. Front conveyor sprockets 23 for mounting the two conveyor traction chains 4 are fixedly provided on the front sprocket shaft 22. Conventionally, the front sprocket shaft 22 is connected to a conveyor driver 6.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, the rear sprocket assembly 3 includes a rear sprocket shaft 31 fixedly mounted on the conveyor frame 1, and rear conveyor sprockets 32 for mounting the two conveyor traction chains 4 are rotatably mounted on the rear sprocket shaft 31; a chain tensioner 7 is provided between the rear sprocket shaft 31 and the conveyor frame 1, and the conveyor traction chain 4 is tensioned by the chain tensioner 7 to promote the synchronous operation of the bearing rods 5, which helps to ensure the paint protection effect.

[0024] like Figure 3 and Figure 6 As shown, in this embodiment, the conveyor frame 1 is fixedly provided with two rear sprocket mounting plates 71, and the two rear sprocket mounting plates 71 are respectively provided with rear sprocket mounting grooves 72, the groove openings of the rear sprocket mounting grooves 72 facing away from the front sprocket assembly 2; the rear sprocket shaft 31 is provided with anti-rotation limiting surfaces 73 that abut against the two groove edges of the rear sprocket mounting grooves 72, and the rear sprocket shaft 31 is provided with axial limiting bosses 74 on the sides of the anti-rotation limiting surfaces 73. Through the above structural settings, the axis and circumferential direction of the rear sprocket shaft 31 can be limited. The anti-rotation limiting surfaces 73 and the axial limiting bosses 74 on both sides can be obtained by milling on the rear sprocket shaft 31.

[0025] The chain tensioner 7 includes a chain tensioning seat 75 fixedly disposed at the opening of the rear sprocket mounting groove 72. A tensioning bolt 76 is installed through the chain tensioning seat 75. The rear sprocket shaft 31 is provided with a tensioning screw hole 77. The corresponding end of the tensioning bolt 76 is threadedly connected to the tensioning screw hole 77. During installation, the tensioning bolt 76 is passed through the chain tensioning seat 75 and threadedly connected to the tensioning screw hole 77. Continuing to rotate the tensioning bolt 76 can generate a pulling force on the rear sprocket shaft 31 away from the front sprocket assembly 2 using the threaded connection, until the tensioning bolt 76 can no longer be rotated, thus achieving the desired tensioning effect. After tensioning, the tension of the tensioning bolt 76 and the reverse force of the conveying traction chain 4 cause the rear sprocket shaft 31 to form a radial positioning. This, combined with the aforementioned axial and circumferential constraints, forms a fixed installation of the rear sprocket shaft 31 on the conveyor frame 1.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
