    专利说明:

    The invention relates to transport wagons with a lift for heavy loads, mainly for converters in steel production, with a chassis frame pivoting when shifted to another track, rotated relative to the pivoting frame with different directions of movement and raised and lowered relative to the chassis frames by means of hydraulic cylinder lift frame. The jacking cart is known, several concentric pivoting frames are provided inside the chassis, which in certain angular positions rest on the chassis frame, and in other angular positions they can pass through it. On the pivoting frames there are manufactured and retractable lifting members with a smaller lift stroke than the full lift stroke 1. The converter with the lifter rests on the plate associated with the upper swing frame. Lifting or lowering is carried out in several stages, with locking devices, such as hydraulic cylinders, are provided for each to hold the converter i between lifting steps at a certain height. This requires precise control. Thus, the carriage is difficult to manufacture and operate. Closest to the proposed P9 technical essence and the achieved result is a jack carriage for transportation of steelmaking converters, in which the envelope rests on the lifting frame, and the frame is pivotally connected to the ram being lifted or lowered relative to the chassis frame, which causes expensive and not very hard construction. The swivel frame can rotate on the chassis frame regardless of the lifting frame. When shifting the car to a different path, crossing the rails using its own hydraulic cylinders rests on the ground 2. At the lifting frame itself, the converter is fixed by means of hydraulic cylinders with a short stroke, which allow the converter to be matched to the mounting slot. However, these cylinders do not allow the converter to be raised or lowered. The purpose of the invention is to simplify and reduce the cost of construction. This goal is achieved by the fact that in a jack carriage for transporting steelmaking converters containing a chassis frame rotating relative to the swing frame, the swinging frame can be supported on the ground, and a lifting frame that can be raised and lowered using hydraulic cylinders relative to the running frame, lifting the frame is supported by one row of hydraulic cylinders placed on the chassis frame, and the converter is supported on another row of hydraulic cylinders placed on the lifting frame, the swivel frame being placed on the mast for rotation. The lifting frame can rest on top of the support of the swing frame. By mounting oppositely acting (up or down) hydraulic cylinders on a solid and rigid lifting frame, the jack carriage is made particularly rigid. The rotational fixing of the swinging frame on the lifting frame ensures that the jacking car moves to another path by crossing the rails by turning on the hydraulic cylinders between the lifting frame and the running frame, due to which dL is not intended for this purpose. efficient hydraulic cylinders. According to the invention, the pivoting frame is rotatably mounted on the underside of the lifting frame by means of a compression bearing and can be directly supported on the ground. FIG. 1 shows the proposed trolley with the converter in the lowered position, side view; in fig. 2 is the same, with the converter in the raised position, partial section, in FIG. The same, plan view; in fig. 4 - the same, in the raised position of the chassis frame with the converter lowered, side view. . . . The chassis frame 1 of the trolley carriage 2 wheels 3 moves along the rails 4. On the chassis frame 1 there are several hydraulic power cylinders 5 fixed by lower ends of the pistons b, the upper ends 7 of the cylinders connect the lifting frame 8 lifting of the rotary mechanism 9. On the lower side 10 of the lifting frame, with the help of an axial load bearing 11, such as a roller, the rotating frame 12 can rotate, which on the lower side has an annular bearing surface 13. On the lifting frame 8 there are several Only additional hydraulic cylinders 14, the pistons 15 of which are pushed upwards. On the ends of the pistons, the paws 16 of the converter 17 are supported. On the rotary frame there is a rotation actuator 18, which by small gear 19 engages the teeth of the crown 20 of the rotary frame 12 (Fig. 3). When translating the jacking cart from the position shown in FIG.
    at the intersection of the rails, the lifting-turning mechanism 9 is lowered to another direction, so that it is supported on the ground by an annular support surface 13. The hydraulic cylinder 5 is then activated, whereby the drive frame 1 is raised for some distance h (Fig. 4), and the flanges of the wheels raise the rail. The converter 17, the swing frame 12 and the lift frame 8 remain in their original position. Then, when the rotary actuator 18 of travel-frame 1 with lifting frame 8 and converter 17 is turned on a new path, and due to the operation of cylinder 5 in the opposite direction, the wheels are lowered onto other rails, and the swing frame 12 again rises some distance from the ground.
    Next, the jack carriage with the converter moves to a new place (a place of melting or repair) and, by actuating both cylinders 5 and 14, rises to the position shown in FIG. 2, and the converter is suspended by local means. Then, by the reverse action of the tilt-up mechanism, the unloaded jack carriage is discharged to the side.
    In the proposed trolley, the hydraulic cylinders whose pistons are pushed up are fixed on
    lifting frame 8. However, it is possible to mount them on a rotating frame 12.
    Due to the presence of pistons 6 and 15 hydraulic cylinders which are protruding in opposite directions
    high lifting height is achieved by simple means, which eliminates the need to use expensive equipment for locking and controlling, and at the same time rigidity of the structure increases due to the installation of converter paws at the ends of the pistons, namely due to the fact that the center of gravity of converter .
