Description

Technical Field

[0001] This invention belongs to the field of straightening equipment technology, specifically relating to a straightening machine and its method of use for straightening the deformation of the bottom beam of a rail transport frame. Background Technology

[0002] The rail transport frame is an important supporting component in the rail transport process. Its bottom beam must have a high degree of straightness to ensure the stability of the transport process.

[0003] Currently, in existing technologies, the straightening of large welded components such as the bottom beam of a rail transport frame typically relies on two methods. One method involves operators using experience to heat the deformed area with a flame, followed by hammering to reshape it. This method offers high strength but low straightening accuracy, and improper heating can easily lead to a decline in material properties. The other method involves placing the workpiece under a fixed pressure head for overall pressure application. However, this method has the following drawbacks: First, the bottom beam of the rail transport frame relies on a crane to hoist it onto the straightening box, making it inconvenient to move it in and out of the workstation. Second, the bottom beam of the rail transport frame has a complex structure with inconsistent top heights, while the pressure head of a general-purpose press is usually a single plane. During pressing, it cannot adapt to different thickness areas, resulting in local "suspension" of the workpiece without effective constraint, or local "overpressure" causing stress concentration, leading to unstable positioning or new damage. Furthermore, overall pressing is difficult to apply precise pressure to complex local deformations. Summary of the Invention

[0004] Based on the above-mentioned technical problems, the purpose of this invention is to provide a straightening machine and its method for straightening the deformation of the bottom beam of a rail transport frame. The straightening machine is easy to feed into or remove from the straightening station, and can press different thickness areas on the top of the bottom beam of the rail transport frame separately to achieve zoned positioning and uniform constraint positioning effect, eliminating the situation of suspension or overpressure caused by contour differences, and applying localized and precise pressure to the deformation of different parts of the bottom beam of the rail transport frame, thereby improving the accuracy of the straightened shape.

[0005] The specific technical solution is as follows: A straightening machine for straightening the deformation of the bottom beam of a rail transport frame includes: a housing, a conveying mechanism, multiple limiting mechanisms, a moving trough, multiple moving seats, multiple drive cylinders, and multiple straightening mechanisms; the conveying mechanism is mounted on the housing, and the bottom beam of the rail transport frame is placed on the conveying mechanism; the multiple limiting mechanisms are respectively mounted on the housing, and the limiting ends of the limiting mechanisms are in contact with the top of the bottom beam of the rail transport frame; the moving trough is located on the top of the housing, and the multiple moving seats are respectively embedded in the moving trough; the drive cylinders are mounted inside the housing, and the telescopic ends of the drive cylinders are connected to the moving seats; the straightening mechanisms include straightening cylinders and straightening plates, the straightening cylinders are mounted on the moving seats, and the telescopic ends of the straightening cylinders are connected to the straightening plates.

The bracket is set on the box body, the roller frame is fixed on the bracket, and multiple rollers are installed on the roller frame.

[0007] In the above technical solution, the limiting mechanism includes: a limiting frame, a limiting cylinder, and a limiting plate.

[0011] The present invention provides a straightening machine for straightening the deformation of the bottom beam of a rail transport frame. Compared with the prior art, the advantages are as follows: 1. Placing the bottom beam of the rail transport frame on the conveying mechanism facilitates the feeding or removal of the bottom beam into or out of the straightening station.

[0012] 2. By setting multiple limiting mechanisms, different thickness areas on the top of the bottom beam of the rail transport frame are pressed separately to achieve zoned positioning and uniform constraint positioning effect, eliminating the situation of suspension or overpressure caused by contour differences.

[0015] The following are specific implementation cases and appendices. Figure 1-4 The present invention will be further described, but the present invention is not limited to these embodiments.

[0016] A straightening machine for straightening the deformation of the bottom beam 10 of a rail transport frame, such as Figure 1-4 As shown, the system includes: a housing 11, a conveying mechanism, multiple limiting mechanisms, a moving trough 12, multiple moving seats 13, multiple driving cylinders 14, and multiple straightening mechanisms; the conveying mechanism is mounted on the housing 11, and the bottom beam 10 of the rail transport frame is placed on the conveying mechanism; multiple limiting mechanisms are respectively mounted on the housing 11, and the limiting ends of the limiting mechanisms are in contact with the top of the bottom beam 10 of the rail transport frame; the moving trough 12 is mounted on the top of the housing 11, and multiple moving seats 13 are respectively embedded in the moving trough 12; the driving cylinders 14 are mounted inside the housing 11, and the telescopic ends of the driving cylinders 14 are connected to the moving seats 13; the straightening mechanism includes a straightening cylinder 15 and a straightening plate 16, the straightening cylinder 15 is mounted on the moving seats 13, and the telescopic ends of the straightening cylinder 15 are connected to the straightening plate 16.

[0017] Using the above structure, the bottom beam 10 of the rail transport frame is placed on the conveying mechanism by a traveling crane, and the bottom beam 10 is pushed. The conveying mechanism sends the bottom beam 10 into or out of the straightening station. Multiple limiting mechanisms press on different thickness areas on the top of the bottom beam 10 of the rail transport frame, achieving zoned positioning and uniform constraint, eliminating the situation of suspension or overpressure caused by contour differences. The driving cylinders 14 drive the corresponding moving seats 13 to move along the moving grooves 12, so that the straightening cylinders 15 move to the deformed part of the bottom beam 10 of the rail transport frame. The extension and retraction of the straightening cylinders 15 drives the straightening plate 16 to move, applying local pressure to the deformed part, thereby improving the accuracy of the straightened shape.

[0018] Specifically, by setting up multiple straightening mechanisms, it is possible to simultaneously perform straightening operations on multiple positions of the bottom beam 10 of the rail transport frame, thereby improving work efficiency.

[0019] In an embodiment of the present invention, the conveying mechanism includes: a bracket 17, a roller frame 18 and a plurality of rollers 19. The bracket 17 is disposed on the housing 11, the roller frame 18 is fixed on the bracket 17, and a plurality of rollers 19 are mounted on the roller frame 18.

[0020] By placing the bottom beam 10 of the rail transport frame on the rollers 19, it is easy to send the heavy bottom beam 10 of the rail transport frame into or out of the straightening station.

[0021] In an embodiment of the present invention, the limiting mechanism includes: a limiting frame 20, a limiting cylinder 21, and a limiting plate 22. The limiting frame 20 is disposed on the housing 11, the limiting cylinder 21 is fixed on the limiting frame 20, and the telescopic end of the limiting cylinder 21 is connected to the limiting plate 22.

[0022] The operation of the limit cylinder 21 drives the limit plate 22 to move up and down, so as to perform zone positioning of different thickness areas on the top surface of the bottom beam 10 of the rail transport frame. This eliminates the situation where the workpiece cannot adapt to different thickness areas during pressing, resulting in local "suspended" and unconstrained parts, or local "overpressure" causing stress concentration, which leads to unstable positioning or new damage.

[0023] In an embodiment of the present invention, the cross-section of the movable groove 12 is stepped, and a slide rod 23 is provided inside the movable groove 12, and the slide rod 23 passes through the bottom of the movable seat 13.

[0024] By setting the slide bar 23, the movable seat 13 is guided, making its movement smoother.

[0025] In an embodiment of the present invention, a position sensor 24 is provided on the movable seat 13, a first displacement sensor 25 is provided on the straightening plate 16, and a second displacement sensor 26 is provided on the limiting plate 22.

[0026] The position of the moving seat 13 is detected by the position sensor 24; the first displacement sensor 25 on the straightening plate 16 is used to monitor the displacement of the straightening cylinder 15 in real time, thereby achieving precise control of the straightening stroke; the second displacement sensor 26 on the limit plate 22 is used to monitor the pressing stroke of the limit plate 22 in real time to ensure reliable positioning.

[0027] A method for using a straightening machine for straightening the deformation of the bottom beam of a rail transport frame includes the following steps: S1: The crane places the bottom beam 10 of the rail transport frame on the roller 19 and pushes the bottom beam 10 of the rail transport frame, thereby sending the bottom beam 10 of the rail transport frame into the straightening station. S2: Multiple limit cylinders 21 extend respectively, so that multiple limit plates 22 press on different areas of the top surface of the bottom beam 10 of the rail transport frame, thereby achieving the effect of zoned positioning and uniform constraint, eliminating the situation of suspension or overpressure caused by contour differences. S3: Multiple drive cylinders 14 drive the corresponding moving seats 13 to move, so that multiple straightening cylinders 15 move to multiple deformed points on the bottom beam 10 of the rail transport frame, and multiple straightening cylinders 15 extend to drive the straightening plate 16 to move, applying local pressure to multiple deformed positions, thereby improving the accuracy of the straightened shape.
