Description

Technical Field

[0001] The utility model relates to the technical field of conveying devices, in particular to a track device of a walking beam used for conveying plates. Background Art

[0002] In modern industrial production, walking beams are a crucial piece of equipment, widely used in production lines such as cold rolling mills, to precisely convey sheet metal. With the continuous advancement of industrial technology and increasing production demands, the use and importance of walking beams are becoming increasingly prominent. However, the design and operation of the track structure that underpins the walking beam's operation have, to a certain extent, restricted production efficiency.

[0003] Currently, the walking beam tracks widely used in cold rolling mills are mostly one-piece structures. While this track structure is sturdy and durable, it also has significant drawbacks. Due to its bulk and weight, one-piece tracks require significant time and manpower to install and remove. This is especially true when the tracks wear out from long-term use or exhibit serious problems such as gnawing, making track replacement significantly more difficult.

[0004] Specifically, the replacement of integrated rails is mainly limited by the following aspects:

[0005] Space limitations: Due to the large size of the track, replacement often requires a large operating space. However, in actual production environments, such space is often difficult to meet, which increases the difficulty and complexity of replacement.

[0006] Difficulty in assembly and disassembly: The assembly and disassembly process of the integrated track is cumbersome and requires specialized tools and extensive manpower. This not only increases replacement costs but can also cause extended downtime of the production line, impacting productivity.

[0007] Safety hazards: Track replacement is a complex operation requiring high-altitude work, which often presents significant safety hazards. Accidents can cause serious damage to personnel and equipment.

[0008] In view of the above problems, it is particularly important to design a track structure that is more flexible and easy to replace. Summary of the Invention

[0009] The utility model provides a walking beam split track, which has higher adaptability and flexibility, can significantly reduce the difficulty and cost of replacement, and improve replacement efficiency; at the same time, since the disassembly and assembly process of the split track is simpler, the occurrence of safety hazards is also reduced.

[0010] In order to solve the above problems, the technical solution adopted by the present invention is:

[0011] It includes an orbit body and an orbit mounting bracket, and the orbit body is installed above the orbit mounting bracket; the orbit body includes a convex orbit and a concave orbit in an up-and-down structure, the convex orbit has protrusions, the concave orbit has grooves matching the protrusions of the convex orbit, and the convex orbit and the concave orbit are connected by bolts.

[0012] In the above technical solution, a more specific technical solution may further be: the concave orbit is fixedly connected to the orbit mounting bracket as a whole.

[0013] Further, the convex orbit is located above the concave orbit.

[0014] Further, there are several bolts, and they are evenly distributed on the center line of the orbit body.

[0015] Further, the distance between the bolts is 250 mm.

[0016] Further, reinforcing support plates are respectively provided on both sides of the orbit mounting bracket.

[0017] Due to the adoption of the above technical solution, the utility model has the following beneficial effects compared with the prior art:

[0018] 1. The utility model has the advantages of flexibility and adjustability, is convenient for installation and disassembly, and has the characteristics of reliable use.

[0019] 2. The utility model splits the orbit main body into a convex orbit and a concave orbit in an up-and-down structure, and connects the two through bolts, realizing the flexible assembly and disassembly of the orbit; compared with an integral orbit, the utility model has higher adaptability and flexibility, can significantly reduce the replacement difficulty and cost, improve the replacement efficiency, and at the same time, since the disassembly and assembly process of the split-type orbit is simpler, the occurrence of potential safety hazards is also reduced.

[0020] 3. The utility model fixedly connects the concave orbit of the orbit main body to the orbit mounting bracket as a whole, so that it has significant advantages in terms of structural stability, safety, maintenance convenience and overall performance.

[0021] 4.

[0028] The following further details the present utility model in conjunction with the accompanying drawings

[0029] Such as Figures 1 - 3 Shown is a split type track of a walking beam, which includes a track body 1 and a track mounting bracket 2, and the track body 1 is installed above the track mounting bracket 2; the track body 1 includes a convex track 1-1 and a concave track 1-2 in an up-and-down structure. The convex track has a protrusion, and the concave track 1-2 has a groove matching the protrusion of the convex track 1-1. The convex track 1-1 and the concave track 1-2 are connected by bolts 3. That is, the track body 1 is split into the convex track 1-1 and the concave track 1-2 in an up-and-down structure, and the two are connected by bolts 3, realizing flexible assembly and disassembly of the track; compared with the integral track, the present utility model has higher adaptability and flexibility, can significantly reduce the replacement difficulty and cost, improve the replacement efficiency. At the same time, since the disassembly and assembly process of the split type track is simpler, the occurrence of potential safety hazards is also reduced

[0030] The convex track 1-1 is located above the concave track 1-2

[0031] The concave track 1-2 is fixedly connected to the track mounting bracket 2 as a whole. With such a setting, it has significant advantages in terms of structural stability, safety, maintenance convenience and overall performance

[0032] There are several bolts 3, and they are evenly distributed on the center line of the track body 1

[0033] The distance between the bolts 3 is 250mm. With such a setting, by calculating the corresponding points of the track moment distribution of the convex track 1-1 part and making the distribution of the bolts 3 required for installation according to the corresponding points of the moment distribution, the convex track 1-1 part can be well fixed on the concave track 1-2 part, and during use, it will not deform due to stress and cause the walking beam to malfunction

[0034] Reinforcing support plates 4 are respectively provided on both sides of the track installation bracket 2. With such a setting, not only the structural stability is enhanced and the load-bearing capacity is improved, but also the force distribution is optimized, the safety performance is enhanced, and different installation environments and conditions are adapted. Specific embodiments:

[0036] A split track for a walking beam. The shape of the convex rail 1-2 of the split track is a convex shape. The outer dimensions of the convex frame are 3900 mm in length, 125 mm in width, and 26 mm in height. 15 counterbores are machined on the center line of the convex rail for fixing the convex rail 1-1 on the concave rail 1-2. The diameter of the counterbore is 22 mm and the depth is 18 mm. On the basis of the counterbore, through holes with a diameter of 13.5 mm are drilled at the centers of the counterbores. Machining starts from the position of the first hole 200 mm along the center line from one side of the convex rail 1-1, with an interval of 250 mm, for a total of 15.

[0037] Since the convex rail 1-1 is installed on the concave rail 1-2, when the convex rail 1-1 wears out, only the convex rail 1-1 part needs to be replaced to complete the replacement and maintenance of the track.

[0038] The specific replacement and maintenance methods are as follows:

[0039] After jacking up the moving beam of the walking beam by a certain height, weld and fix the moving beam to the static beam with a stop iron, remove the fastening bolts 3 of the convex rail 1-1 part of the split rail, and use a hoist to extract and separate the convex rail 1-1 part from the concave rail 1-2 part. Use a crane to directly lift the convex rail 1-1 part out of the misaligned hole formed by the moving beam and the static beam. According to this method, lift the new convex rail 1-1 part into the misaligned hole, use a hoist to lift it onto the interface of the concave rail 1-2 part, align and install the bolt holes, and then fasten the convex rail part to the concave rail 1-2 part. Then cut off the fixed stop iron on the moving beam, and then lower the moving beam. Check the track accuracy after installation to complete the maintenance. Through practice, it is proved that after the split rail of the walking beam of the cold rolling finishing unit is put into use, it can effectively reduce the maintenance difficulty and technical content of replacing the walking beam track, reduce the personnel configuration for replacing the walking beam track and the requirements for the professional ability of fitters. And because there is no need to remove the static beam and the related automatic electrical components, starting from the essence of this problem, the number of mechanisms and hoisting that need to be disassembled and assembled is reduced, and there is no need for automatic personnel to cooperate. Therefore, the maintenance and replacement time is shortened by about 3 to 4 hours. Therefore, 4 fitters can be arranged for maintenance personnel to carry out normal replacement. The streamlined personnel can be used for the maintenance of other parts of the cold rolling finishing unit, which can further improve the overall maintenance of the cold rolling finishing unit equipment. At the same time, since the track installation bracket does not move during track replacement, the change in installation accuracy is relatively small, and the original equipment accuracy can be maintained relatively well. Coupled with the relatively high manufacturing accuracy of the convex rail 1-1 part, the impact on the accuracy of the walking beam equipment after replacement is small, meeting the accuracy requirements of the walking beam track equipment. Moreover, it is precisely because the split rail of the walking beam does not need to remove the static beam, there is no large-area pit formed, and the number of potential safety hazards of falling from a height during the maintenance process at this place can be reduced. In addition, since there is no need for hot work, the fire risk of such maintenance is eliminated, and the problems existing during the replacement of the original integral rail of the walking beam are well solved.
