Description

Technical Field

[0001] The utility model relates to the technical field of turnout manufacturing, and particularly relates to a turnover device for track molds. Background Art

[0002] As an important node during the train turning process, the turnout bears the centrifugal force generated by the train turning. The structure and state of the turnout directly determine whether the train can run safely and smoothly. The cross-section of the turnout rail is different from that of the ordinary rail. In order to ensure a smooth connection with the subsequent ordinary rail, it is necessary to forge the heel end section to be the same as the cross-section of the ordinary rail. The pressure required for forging the heel end is large and the mold wears out quickly, so the mold needs to be repaired regularly.

[0003] The working surface of the upper mold faces downward during use, but in order to ensure the convenience and safety of mold repair, the working surface of the upper mold needs to be turned upward during repair and turned downward again after the repair is completed. The total weight of the upper mold is about 4 tons. Traditionally, the turnover of the upper mold relies on manual dragging in cooperation with the overhead crane, which has complex operation, high labor intensity, and direct contact between workers and the mold, resulting in great potential safety hazards during the operation. How to use a mechanical device to replace manual operation to complete the mold turnover, thereby improving production efficiency and reducing safety risks is an urgent problem to be solved. Content of the Utility Model

[0004] To solve the problems in the above background art, the utility model provides a turnover device for track molds, which can turnover different heel-end profiling molds, improving product quality, reducing the risk of mold repair, reducing the labor intensity of workers, enhancing production efficiency, and avoiding damage to the mold during the turnover process.

[0005] The utility model adopts the following technical solutions:

[0006] A turnover device for track molds includes a base, a rotating structure, a first turnover frame, and a second turnover frame. The rotating structure is arranged in the middle of the base.

[0008] Further, both the upper and lower parts of the first rotating shaft hole are semi-circular, and the middle part is rectangular. Limiting parts are arranged at both ends of the rotating shaft outside the first rotating shaft frame and the second rotating shaft frame.

[0009] Further, first rib plates are installed on both sides of the first flipping frame close to the rotating structure, second rib plates are installed on both sides of the second flipping frame close to the rotating structure, second rotating shaft holes are formed in both the first rib plates and the second rib plates, the first rib plates and the second rib plates are located between the first rotating shaft frame and the second rotating shaft frame, and the rotating shaft passes through the second rotating shaft holes of the first rib plates and the second rib plates.

[0010] Further, both the first flipping frame and the second flipping frame include two first brackets arranged in parallel, a support plate erected between the two first brackets, and several second brackets. The first brackets are perpendicular to the rotating shaft. The support plate is used to carry the side surface of the track mold, and several of the second brackets are used to carry the bottom surface of the track mold.

[0011] Further, the locking structure includes a screw rod, a first locking nut, third rib plates and fourth rib plates respectively arranged on the sides of the first flipping frame and the second flipping frame away from the rotating shaft structure.

[0022] Such as Figures 1 to 3An orbital mold flipping device shown in the figure includes a base 1, a rotating structure 2, a first flipping frame 3, and a second flipping frame 4. The rotating structure 2 is arranged in the middle of the base 1. The first flipping frame 3 and the second flipping frame 4 are rotatably connected to the rotating structure 2. An orbital mold placement position 5 is formed between the first flipping frame 3 and the second flipping frame 4. The first flipping frame 3 and the second flipping frame 4 are connected by a locking structure 6 at one end away from the rotating structure 2. When the orbit needs to be flipped, place the upper mold in the opened first flipping frame 3 and second flipping frame 4. According to the flipping direction, place the orbit in the first flipping frame 3 or the second flipping frame 4. After placement, close the first flipping frame 3 and the second flipping frame 4, and lock the locking structure 6 to fixedly connect the first flipping frame 3 and the second flipping frame 4. Use a crane to drag the first flipping frame 3 and the second flipping frame 4 to rotate the first flipping frame 3 and the second flipping frame 4 along the rotating structure 2. After rotation, by unlocking the locking structure 6, rotate the first flipping frame 3 or the second flipping frame 4 to the original handling side, thereby realizing the flipping of the orbit. Compared with the existing method, the orbit is restricted within the device, and the operator does not need to be in close contact, reducing the safety risk caused by situations such as mold slippage.

[0023] Specifically, as Figure 1 and Figure 2 shown, the number of rotating structures 2 is two and they are respectively arranged at both ends of the base 1. The rotating structure 2 includes a first rotating shaft 24 frame 21 and a second rotating shaft 24 frame 22, a first rotating shaft 24 hole 23 opened on the first rotating shaft 24 frame 21 and the second rotating shaft 24 frame 22, a rotating shaft 24 arranged in the first rotating shaft 24 hole 23. The first flipping frame 3 and the second flipping frame 4 are hinged to the rotating shaft 24. The upper and lower parts of the rotating shaft 24 hole are semi-circular, and the middle part is rectangular. The two ends of the rotating shaft 24 located outside the first rotating shaft 24 frame 21 and the second rotating shaft 24 frame 22 are provided with limiting parts 25. The two sides of the first flipping frame 3 close to the rotating structure 2 are installed with first rib plates 31, and the two sides of the second flipping frame 4 close to the rotating structure 2 are installed with second rib plates 41. Second rotating shaft 24 holes are opened on both the first rib plates 31 and the second rib plates 41. The first rib plates 31 and the second rib plates 41 are located between the first rotating shaft 24 frame 21 and the second rotating shaft 24 frame 22. The rotating shaft 24 passes through the second rotating shaft 24 holes of the first rib plates 31 and the second rib plates 41. When the first flipping frame 3 and the second flipping frame 4 are pulled by a crane, the rotating shaft 24 slides up and down along the rotating shaft 24 hole, so that the rotating shaft 24 has a larger displacement space when being pulled.

[0024] Specifically, as Figure 1 and Figure 2As shown, the first flipping frame 3 and the second flipping frame 4 both include two first brackets 32 arranged in parallel, a pallet 33 erected between the two first brackets 32, and several second brackets 34. The first brackets 32 are perpendicular to the rotating shaft 24. The pallet 33 is used to carry the side of the track mold, and several of the second brackets 34 are used to carry the bottom surface of the track mold. The track mold is placed on the second brackets 34 of the first flipping frame 3 or the second flipping frame 4. When the first flipping frame 3 and the second flipping frame 4 are pulled to flip, the side of the track mold contacts the pallets 33 of the first flipping frame 3 and the second flipping frame 4.

[0025] Specifically, as Figure 2 and Figure 3 shown, the locking structure 6 includes a screw 61, a first locking nut 62, third rib plates 35 and fourth rib plates 42 respectively arranged on the side edges of the first flipping frame 3 and the second flipping frame 4 away from the structure of the rotating shaft 24. Circular holes are formed on both the third rib plates 35 and the fourth rib plates 42. The screw 61 and the first locking nut 62 are detachably connected to the circular holes, and the screw 61 is threadedly connected to the first locking nut 62. When the first flipping frame 3 and the second flipping frame 4 are buckled, the circular holes on the third rib plates 35 and the fourth rib plates 42 coincide. By passing the screw 61 through the circular holes on the third rib plates 35 and the fourth rib plates 42 and locking the screw 61 with the first locking nut 62, the first flipping frame 3 and the second flipping frame 4 are locked, so as to prevent the first flipping frame 3 and the second flipping frame 4 from separating during pulling and causing operation accidents.

[0026] Specifically, as Figure 1 and Figure 3 shown, bolt holes are provided at the four corners of the base 1, anchor bolts 7 connected to the bottoms of the bolt holes, and second locking nuts 8 threadedly connected to the tops of the anchor bolts 7. The second locking nuts 8 are located above the bolt holes. The bottom plate restricts the first flipping frame 3, the second flipping frame 4 and the rotating assembly. Since the track mold is relatively heavy, the bottom plate is fixed to the ground by a set of anchor bolts 7 to prevent the mechanism from sliding when rotating the track.
