[0002] The bogie is the running gear of a rail vehicle, much like a person's legs. It is one of the most critical components of a rail vehicle. After the crossbeams or side beams on the bogie are manufactured, they may bend or deform, and in this case, they need to be corrected.
[0003] An existing patent application (CN103691770B) discloses a subframe inspection and correction device for a freight car bogie. This device comprises a base, a longitudinal rigid beam, positioning components, clamping components, a detection datum, and correction components. The longitudinal rigid beam is fixedly mounted on the base. The positioning components, clamping components, detection datum, and correction components are mounted on the longitudinal rigid beam. The positioning components include vertical positioning components, longitudinal positioning components, and lateral positioning components. The clamping components include vertical clamping components and longitudinal clamping components. The correction components include lateral correction screws and vertical correction screws. This device integrates positioning, clamping, inspection, and correction, is easy to operate, and offers simple inspection methods. It employs a datum conversion method to transform the key dimensions of the subframe after welding during the production of the freight car bogie into easily detectable planar dimensions. If dimensional deviations are found, the correction components can force deformation of the subframe and, combined with heating, correct it to meet design requirements.
[0004] However, the device requires fixing multiple positions during the correction process, which takes a long time and affects the efficiency of the correction. In addition, the device is also difficult to use for correction. Utility Model Content

[0023] The moving component 7 includes an electric cylinder 71, a sliding plate 72, a rack 73, a gear 74, a placement plate 75, a second connecting rod 76, a clamping plate 77, and a slide 78. The placement plate 75 is located between the tops of the two sets of first connecting rods 2. The sliding plate 72 is symmetrically slidably connected to both sides inside the placement plate 75. A rack 73 is provided on one side of the sliding plate 72. A gear 74 is rotatably connected to the middle fixed axis at the bottom inside the placement plate 75. The gear 74 meshes with the rack 73. An electric cylinder 71 is provided on one side of the placement plate 75. The output end of the electric cylinder 71 is connected to the sliding plate 72.
[0024] A placement plate 75 is provided at the middle position of the top of the slide plate 72. The gear 74 has a connecting shaft inside, and the connecting shaft is connected to the placement plate 75, so that the gear 74 can rotate on a fixed axis. A through hole is provided on one side of the placement plate 75. The output end of the electric cylinder 71 extends through the through hole to the inside of the placement plate 75 and connects with the slide plate 72 for easy connection. A sliding groove 78 is provided in the middle of the top of the placement plate 75.

[0025] Working principle: During the correction process, the device is first placed on top of the moving assembly 7. Then, the electric cylinder 71 is activated, which moves one slide plate 72 and rack 73. The rack 73 then rotates the gear 74, causing the other rack 73 to move in the opposite direction, bringing the two slide plates 72 closer together. The second connecting rod 76 at the top of the slide plate 72 then moves the two clamping plates 77 closer together, fixing the crossbeam or side beam on the bogie. Then, the drive motor 6 is activated, which rotates the shaft 5 and the incomplete gear 4. During the rotation, the incomplete gear 4 drives the gear ring 3 to reciprocate, and through the first connecting rod 2 and the moving assembly 7, it reciprocates, thus moving the crossbeam or side beam on the moving assembly 7. At this time, the hydraulic cylinder 9 is activated, which moves the pressure plate 8 reciprocating downward, flattening multiple positions of the crossbeam or side beam, thus completing the correction work.
