Description

Technical Field

[0001] This utility model relates to the technical field of car body shaping equipment, and specifically to a railway freight car body shaping device. Background Technology

[0002] During long-term operation, railway freight cars are prone to deformation due to various external forces, such as collisions and compression. Deformation not only affects the appearance of the freight car, but more importantly, it reduces its operational safety and cargo-carrying capacity.

[0003] Chinese patent publication number CN203526248U discloses a hydraulic vehicle body shaping machine. The machine frame has a lower pull arm with a pull hook at its front end. The rear end of the pull arm is connected to the piston rod of a moving cylinder. A column is mounted on the frame, with its upper end hinged to an upper pull arm. The front end of the upper pull arm has an upper pull hook, and its rear end is connected to the piston rod of a clamping cylinder. The cylinder body of the clamping cylinder is fixed to the column. A correction cylinder is mounted on the front side of the column, with its piston rod perpendicular to the column. The upper side of the correction cylinder's cylinder body is connected to the piston rod of a lifting cylinder via a steel wire rope. The cylinder body of the lifting cylinder is fixed to the machine frame.

[0004] Currently, in the work of shaping and repairing railway freight cars, the main method used is to adjust and repair the car body using a door frame shaping machine. However, this method has many drawbacks: First, the contact area between the shaping block (correction cylinder) of the door frame shaping machine and the car body is small, which cannot meet the requirements of car body shaping. In addition, most of the existing car body shaping devices can only correct the protruding parts of the car body and cannot correct the dented parts of the car body. It is necessary to manually enter the car body for hammering repair. Therefore, it is necessary to develop a car body shaping device with better correction effect. Utility Model Content

[0005] The purpose of this utility model is to provide a railway freight car body shaping device, which solves the problem of poor correction effect of traditional car body shaping devices.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] This utility model provides a railway freight car body shaping device, including a shaping plate; a sleeve, the sleeve being fixedly disposed on the upper part of the shaping plate; and a groove, the groove being disposed on the lower part of the shaping plate, wherein an electromagnetic chuck is disposed in the groove, and the bottom surface of the electromagnetic chuck is flush with the bottom surface of the shaping plate.

[0008] Furthermore, the sleeve is provided with a clamping assembly inside, which includes a clamping plate and a bolt. The bolt is disposed through the side of the sleeve, and the clamping plate is connected to the bolt through a bearing.

[0009] Furthermore, the clamping plate is arc-shaped.

[0010] Furthermore, the interior of the groove is provided with flame-throwing holes.

[0011] Furthermore, multiple flame-emitting holes are provided, and the multiple flame-emitting holes are arranged around the outer side of the electromagnetic chuck.

[0012] Furthermore, the shaping plate is rectangular in shape.

[0013] Technical effects of this utility model:

[0014] Compared with the prior art, the railway freight car body shaping device of this utility model greatly increases the contact area between the device and the car body by setting a shaping plate, groove and electromagnetic chuck, which effectively improves the shaping effect. Moreover, the device can apply pressure and tension to the car body, which helps to repair the protrusions and depressions of the car body and complete the overall shaping of the car body.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example:

[0023] like Figure 1-4 As shown in the figure, a railway freight car body shaping device according to this embodiment includes a shaping plate 2, which is rectangular in shape and is used to apply pressure or tension to deformed parts of the car body to achieve shaping and correction of the car body; a sleeve 1, which is fixedly installed on the upper part of the shaping plate 2 and is used to connect to a hydraulic cylinder, which drives the shaping plate 2 to move to complete the shaping of the car body; and a groove 5, which is installed on the lower part of the shaping plate 2 and contains an electromagnetic chuck 4. The bottom surface of the electromagnetic chuck 4 is flush with the bottom surface of the shaping plate 2 and is used to apply tension to the dents in the iron parts of the car body, thereby promoting the restoration of the shape of the part. By setting the shaping plate 2, the groove 5 and the electromagnetic chuck 4, the contact area between the device and the car body is greatly increased, which effectively improves the shaping effect. Moreover, the device can apply both pressure and tension to the car body, which helps to repair the protrusions and dents of the car body and complete the overall shaping of the car body.

[0024] The sleeve 1 is equipped with a clamping assembly 3 inside. The clamping assembly 3 includes a clamping plate 33 and a bolt 31. The bolt 31 is disposed through the side of the sleeve 1. The clamping plate 33 is connected to the bolt 31 through a bearing 32. The clamping plate 33 is arc-shaped. The clamping assembly 3 is used to fix the device to the hydraulic cylinder so that the hydraulic cylinder can drive the shaper plate 2 to move. When the device is fixed to the hydraulic cylinder, the bolt 31 is tightened, and the clamping plate 33 moves toward the hydraulic cylinder, thereby clamping the hydraulic cylinder and fixing the device. The inner side of the clamping plate 33 may be provided with protrusions or recesses to engage with the hydraulic cylinder and prevent displacement between the hydraulic cylinder and the clamping plate 33.

[0025] The groove 5 is provided with a flame-blowing hole 6. Multiple flame-blowing holes 6 are arranged around the outside of the electromagnetic chuck 4. The flame-blowing holes 6 are used to heat the vehicle body to reduce stress concentration in deformed parts of the vehicle body, making vehicle body shaping easier.

[0026] Working principle

[0027] During vehicle body shaping, tighten bolt 31, and clamp 33 moves toward the hydraulic cylinder to clamp it, thus fixing the device to the hydraulic cylinder. Then, the shaping machine moves the hydraulic cylinder to the protruding part of the vehicle body, and the flame port 6 is activated to heat the part, extending the hydraulic cylinder. The shaping plate 2 applies pressure to the vehicle body, shaping the protruding part. Then, the hydraulic cylinder is moved to the concave part of the vehicle body, and the flame port 6 is activated to heat the part. The electromagnetic chuck 4 is activated, and the device applies tension to the vehicle body, shaping the concave part. Finally, the flatness after shaping is checked, and any areas that are not properly shaped are shaped again.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
