The utility model discloses a bicycle parking frame, and one side of the interior of a mounting L-shaped plate is rotatably connected with a telescopic supporting rod, and the other side of the interior of the mounting L-shaped plate is rotatably connected with a deflection supporting rod. Through a first limiting arc groove in the mounting L-shaped plate, the telescopic supporting rod can conveniently drive a first supporting wheel to deflect; a telescopic supporting rod is locked and limited through a locking rotary knob, so that the wheel is preliminarily supported, a deflection supporting rod conveniently drives a second supporting wheel to deflect through a second limiting arc groove in a mounting L-shaped plate, and under the supporting effect of a supporting torsional spring, the deflection supporting rod is preliminarily supported and limited conveniently; the first supporting wheel and the second supporting wheel are rotated to be attached to the edge of the bicycle wheel, so that the bicycle wheel is effectively supported, and the stability of the parking frame in the actual bicycle supporting process is ensured.

The utility model relates to railway vehicle locomotive overhauling equipment technical field discloses a kind of locomotive trouble clearer dismounting device, including main support, one support structure, two support structures, track sliding structure, safety pin and several jacks;The main support is four cuboid truss structure, and the top of main support is provided with wheel axle beam, and wheel axle beam connects track sliding structure, and track sliding structure is used to press and place this device on rail;The first sleeve column sliding connection on the first sleeve on the bottom plane of main support is passed through one support structure;The second sleeve column sliding connection that is set on one support structure is passed through second sleeve and two support structures;Safety pin is used to fix the relative position between one support structure and two support structures.The utility model can realize the mechanization, precision and single-person operation of HXD3CA type electric locomotive trouble clearer dismounting by special device, so as to reduce labor cost and improve operation safety.
