[0002] The locomotive maintenance operation area of ​​TISCO Logistics Department is a professional maintenance operation area for TISCO diesel locomotives. During the implementation of the locomotive wheel rim assembly process, there is a process that requires the heated wheel rim to be flipped 180° (the wheel rim (wheel rim) to be installed is heated, and the inner diameter is expanded by heat before being inserted into the wheel core).

[0003] The current process of wheel hoop flipping is as follows: 1. Use a special three-claw hoist to lift the heated wheel hoop with the rim side facing up from the heating pit to the ground support block, and then remove the hoist; 2. Use a steel wire rope to pass through the wheel hoop and lift it again; 3. After the wheel hoop is suspended in the air, manually assist in pushing and lowering the overhead crane hook to make the wheel hoist fall to the other side, completing the process of the rim side facing down.

[0004] Existing problems: 1. Low operating efficiency (the sling needs to be replaced twice); 2. High safety risks: three operators need to directly contact the heated wheel hoops; the wire rope is passed through the heated wheel hoops with many sharp edges and angles; there is swinging during the suspended flipping process, which can easily cause collision injuries to the auxiliary pushers.

[0005] The utility model is suitable for the maintenance links such as wheel tyre replacement of the running gear of the traditional diesel locomotive of Taigang. When the existing wheel tyre is turned over after hot installation, it is often due to limited conditions that the wheel tyre is turned over manually, which has the risk of scalding and lifting accidents. The utility model is a set of simple and practical turning methods designed for wheel tyre turning, with low investment, simple operation, high efficiency and safety. It improves the efficiency of turning the wheel tyre of the locomotive after heating, and at the same time ensures the personal safety of the operators. Utility Model Content

[0016] The main features of the existing flipping process are single rigging, mobile flipping and close contact with the human hoop. Changing the mobile to fixed and isolating the human hoop is the primary consideration. Based on this, the utility model discloses a mechanical device that replaces single rigging and manual pushing and flipping with frame support, adaptive clamping, gear force reduction, and suspended hand-crank flipping.

[0017] The device is divided into three parts: 1. Frame part: divided into two left and right support frames, made of 40mm square tube or round tube, and connected and fixed with 4 1300mm long and 30mm diameter round tubes at the bottom and middle lower part. 2. Clamping device (2 sets): arc groove fixtures adapted to the wheel rim (arc diameter 1080mm, arc length 350mm, groove depth and groove width are the height and width dimensions of the rough wheel rim). 3. Hand crank mechanism (2 sets): composed of hand wheel, connecting shaft, master and slave gears.

[0018] The rim fixture used in the flipping device must match the rough wheel rim, rim and tread to ensure reliable fit and clamp the wheelset to prevent accidental falling. Therefore, the rim fixture must be shaped according to the rough wheel rim, and the arc of the fixture must be made to match the rim, and the inclined surface must match the tread.
