Description

This invention relates to the repair of railway rolling stock. A movable stand for repairing freight cars is known, comprising a portal that is movable along the track and mounted on it a transverse beam movable in the vertical pillars, fixing the carriage clamps and the correct jacks being moved from the drive. The disadvantage of such stands is the low efficiency of car repair. The purpose of the invention is to increase the efficiency of repair. This is achieved by the fact that each aforementioned grip is hinged on the vertical rack of the gantry and provided with a prop to move in a horizontal plane, and the movable transverse beam is equipped with guides in which the said jacks are mounted. FIG. 1 shows the proposed stand, front view; FIG. 2 - the same, side view; in fig. 3 is a section A-AI hell of FIG. one; in fig. 4 - replaceable hinged bracket. The stand for repairing freight cars 5 contains a portal 3 movable along the track 2, on which a transverse beam 5 mounted along the guides of 4 vertical posts of portal 3 mounted, and grips 6 for fixing the car driven by the power cylinders 7, each gripper and the power cylinder hinged mounted on the vertical posts of the portal 3, n the correct jacks 8, moving along the guides 9 mounted on the crossbeam 5. To change the concavities of the car farms on the rod of the correct jack 8, a replaceable hanger 10 is mounted, tyvayuscha emy rectifying element. The mobile stand is equipped with cantilever lifting platforms 11 for service personnel, which, in the presence of a brake pad, remain in the upper position. The operation of a steed, made with a symmetrical arrangement of a regular double-sided device, providing alternating production of two cars that are in the position of a conveyor, is performed as follows (in Figs. 1, 3, the right side from the main beam 5 is shown in the working position, and in the original.Each storoiz has its correct jack 8, moving one beam 5).

By means of the actuator 12, the movement of the portal 3 is brought to the right car, the end wall of which is subject to editing. By switching on the power cylinders 7, the grips 6 are led to the pivot racks of the car and, with their pharynx, cover them, fixing the car.

Pad 1} is lowered to its lower position and the worker controlling the dressing process takes a place on it.

The jack 8 carries out editing of the elements of the car face.

After the end of straightening one end of the car, the worker goes to the second working platform of the stand and brings the last one to the end wall of the standing car. After fixing with the grippers of the car and placing the jack in the working position, correct work is performed at the end of the second car.

Upon completion of all work, the stand is brought to its original position, creating the possibility of free movement of the cars on the conveyor.

The proposed mobile stand for the repair of freight carrying wagons improves the efficiency of the use of the repair equipment mounted on it, while ensuring high-quality repair.
