[0026] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0027] As shown in Figure 1, during the sleeper production process, the sleeper mold needs to be flipped to facilitate mold transfer processes such as demolding. This application provides a sleeper mold flipping device, including a main truss 1, a flipping frame, and a flipping power component. It makes adaptive improvements to the sleeper mold; specifically, two metal columns extend from each end of the sleeper mold. One end of the sleeper mold is chamfered to serve as the force point for flipping. The main truss 1 is set on the sleeper mold transfer rail and includes two portal frames. The transverse frame 2 of the flipping mechanism is slidably assembled along the main truss 1. To ensure sufficient flipping space… A lifting mechanism is provided in the middle of the transverse frame 2. The tilting frame is a gate-shaped structure connected to the lower end of the lifting mechanism. The length of the downward extension of both ends of the gate-shaped structure should be adapted to the size of the sleeper mold. It should ensure that the sleeper mold can be tilted freely without interference. A tilting plate 6 is rotatably connected to the inner side of both ends of the tilting frame. The length of the tilting plate 6 is adapted to the distance between the two plug-in columns. The two ends of the tilting plate 6 are respectively provided with plug-in sleeves 10 corresponding to the sleeper mold. The plug-in sleeves 10 match the plug-in columns. The tilting power component can be a stepper motor. The tilting power component is set at both ends of the tilting plate 6 and is correspondingly connected to the tilting plate 6.

[0028] In this embodiment, the middle part of the flip plate 6 is provided with a rotating shaft that is rotatably connected to the lower end of the flip frame. The flipping power component is fixedly installed on the outside of the flip frame and connected to the rotating shaft, thereby realizing precise control of the flip plate 6.

[0029] In one optional embodiment, the tilting frame includes a crossbar 4 and uprights 5. The crossbar 4 is a square steel tube. Telescopic columns 9 are slidably assembled at both ends of the two crossbars 4. The cross section of the telescopic columns 9 is adapted to the inner cavity of the crossbar 4. The part of the telescopic columns 9 extending out of the crossbar 4 is detachably connected to the two uprights 5. The uprights 5 are rotatably connected to the tilting plate 6 and the tilting power component.

[0030] In this embodiment, the crossbar 4 is provided with a drive rod corresponding to two telescopic columns 9. The drive rod can be an electromagnetic rod or a liquid rod, which can drive the telescopic columns 9 to extend or retract, so that the plug sleeve 10 can be fitted onto or disengaged from the plug column.

[0031] As shown in Figure 2, the lifting mechanism includes a first fixed frame 3 and a second fixed frame 7. The first fixed frame 3 is a square structure welded from square steel or angle steel, thus forming a space inside for the second fixed frame 7 to slide longitudinally. Its lower end is an open structure. A lifting rod 8 is provided inside the first fixed frame 3 to drive the second fixed frame 7. The second fixed frame 7 is a square frame. Inside the first fixed frame 3, there are four angle irons that correspond to the corners of the second fixed frame 7 and extend longitudinally to limit the lifting trajectory of the second fixed frame 7, so that the second fixed frame 7 can slide and assemble inside the first fixed frame 3 along the set trajectory. The lower end of the second fixed frame 7 is connected to the crossbar 4 of the tilting frame. The lifting rod 8 extends into the second fixed frame 7 and is connected to the lower middle part of the second fixed frame 7 through a crossbeam, thereby driving the second fixed frame 7. In this embodiment, the lifting rod 8 can be either a pneumatic cylinder or a hydraulic cylinder.

[0032] In one optional embodiment, the main truss 1 extends above the ground rail along the direction of the vertical sleeper mold's flow path. Above the main truss 1 is a slide rail perpendicular to the ground rail, corresponding to the transverse frame 2. Both ends of the transverse frame 2 are equipped with drive wheels corresponding to the slide rails. Drive motors are connected to the drive wheels.

[0033] Alternatively, the main truss 1 can be located above and parallel to the ground rail. In this case, the plug-in columns are set at both ends of the sleeper mold. The specific setting depends on the actual layout and needs, and there are no excessive restrictions here.

[0034] The slide rail is equipped with limiters corresponding to the drive wheels at both ends. The limiters are equipped with touch switches to limit and detect the specific position of the transverse frame 2. In order to ensure force balance, this application provides two lifting rods 8, which are respectively connected to both sides of the second fixed frame 7.

[0035] In an optional embodiment, an elastic pad or elastic element is provided inside the plug sleeve 10. When the telescopic column 9 retracts, the elastic pad or elastic element buffers the movement, preventing damage caused by hard compression of the plug sleeve 10 and improving its service life.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be within the scope of protection of the pending claims of the present utility model.
