Description

Technical Field

[0001] The utility model mainly relates to the technical field of track maintenance, and particularly relates to a turnout automatic flipping trolley. Background Art

[0002] The turnout is the central part of the switch. Due to the vibration and impact force generated when the train passes, and the ballast bed of the turnout heart is not easy to tamp, it is easy to cause vertical wear on the turnout heart and wing rail. If these wears are not dealt with in time, it will exacerbate the damage of the turnout and even affect the train operation safety. Through grinding, the worn layer on the surface of the turnout can be removed, reducing wear and damage. The grinding of the turnout needs to be carried out in all directions, and thus the turnout needs to be flipped over. The turnout is usually made of alloy steel, with a large density and heavy weight. Manually flipping the turnout not only has a large labor intensity, but also consumes a lot of time, affecting the overall work efficiency. Summary of the Utility Model

[0022] Referring to the attached Figures 1 - 3 , a switch frog automatic flipping trolley, including a driving trolley, an installation seat 1 is assembled on the driving trolley, a carrier plate 2 is arranged above the installation seat 1, the carrier plate 2 and the installation seat 1 are connected by a lifting mechanism 3, a flipping mechanism 4 is arranged on the top of the carrier plate 2, and a U-shaped rod 5 driven to flip by it. Both sides of the inner wall of the U-shaped rod 5 are assembled with a second telescopic motor 6, and a clamping plate 7 is fixedly connected to the telescopic end of the second telescopic motor 6.

[0023] In this embodiment, after the driving cart approaches the frog on the workbench, the lifting mechanism 3 drives the carrier plate 2 to lift and lower, and the U-shaped rod 5 lifts and lowers synchronously until the frog is placed inside the U-shaped rod 5. Then, two second telescopic motors 6 are started to drive the two clamping plates 7 to approach each other to clamp the frog. Then, the lifting mechanism 3 drives the carrier plate 2 to lift and lower again to make the clamped frog leave the processing table. At this time, the flipping mechanism 4 drives the U-shaped rod 5 to flip 180 degrees, and the frog flips synchronously. Finally, it is placed on the processing table again, and the flipping and turning of the frog can be completed automatically, which not only reduces the labor intensity, but also has a simple and fast process and improves the overall work efficiency.

[0024] An anti-slip pad 8 is attached to the clamping side of the clamping plate 7 to increase the friction force with the frog and prevent the frog from slipping during the clamping process.

[0025] The flipping mechanism 4 includes a first telescopic motor 41. The telescopic rod of the first telescopic motor 41 extends along the horizontal plane, and an L-shaped rod 43 is fixedly installed at the end. The other end of the L-shaped rod 43 is rotatably connected to a connecting rod 44. The other end of the connecting rod 44 is fixedly connected to the U-shaped rod 5. The middle of the connecting rod 44 is rotatably connected to a connecting link 45. The other end of the connecting link 45 is rotatably connected to a support rod 42 provided on the carrier plate 2.

[0026] In this embodiment, when the first telescopic motor 41 is started and extends forward, the L-shaped rod 43 moves forward synchronously to push the connecting rod 44. The connecting rod 44 cooperates with the limit of the connecting link 45, and then it can flip forward. The U-shaped rod 5 is fixedly connected to the end of the connecting rod 44 and flips synchronously. Similarly, when the first telescopic motor 41 is started and retracts backward, the U-shaped rod 5 can flip backward and return to its original position.

[0027] The lifting mechanism 3 includes a guide rod 31 and a lead screw 33 extending in the vertical direction. The guide rod 31 is fixedly installed on the top of the mounting seat 1 and is slidably connected to the carrier plate 2. The end of the lead screw 33 is connected to a rotating motor 32 assembled on the top of the mounting seat 1 and is threadedly connected to a threaded sleeve 34. The threaded sleeve 34 is fixedly installed at the bottom of the carrier plate 2.

[0028] In this embodiment, after the rotating motor 32 is started to drive the lead screw 33 to rotate, the lead screw 33 rotates in the threaded sleeve 34, and then, in cooperation with the sliding connection between the guide rod 31 and the carrier plate 2, the carrier plate 2 can be driven to lift and lower.

[0029] In the above embodiment, the number of the guide rods 31 is two, and they are oppositely distributed on both sides of the top of the mounting seat 1. The lead screw 33 is located between the two guide rods 31.

[0030] The above-described embodiments merely represent certain implementation manners of the present utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limitations on the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.

[0031] It should be noted that the above content belongs to the technical knowledge scope of the inventor. Due to the vast and extremely complex technical content in this field, the above content of this application does not necessarily constitute prior art.
