Description

 The invention relates to devices for dressing bodies and frames of vehicles, mainly freight cars.

 A known method of editing cars [1], including bending the car assembled from the frame, walls and roof of the car to the side opposite to the bending of the car from the force of weight, and preliminarily connecting the car elements with temporary technological connections excluding their mutual displacement, install the assembled set of parts on two supports located at the ends of the frame, apply bending force to it at an equal distance from the supports, after which the frame, wall and roof are rigidly connected along the entire length, and then relieve the load.

 The disadvantage of this method is that it is designed for overhaul of the car, the equipment intended for its implementation is rather cumbersome.

 Known devices for dressing the bodies of vehicles, in particular cars [2, 3], containing a movable frame for securing the car body and editing tools in the form of movable beams connected to power cylinders.

 These devices are unacceptable for the repair of freight cars because of their large size.

 A device for editing the bodies of vehicles, mainly freight cars [4]. It contains a movable portal, a platform mounted on it, a bridge, with the possibility of moving a trolley with a vertical movement mechanism on the platform, and a dressing device in the form of a power cylinder.

 The device has the same disadvantages, however, in terms of its technical nature, it is most closely offered and can serve as a prototype.

 The problem solved by the proposed device is to simplify the design and ease of work, in particular, the elimination of local gaps, deformation of hatches, lining, etc.

 The problem is solved as follows: in a device for dressing the bodies of vehicles, mainly railway freight cars, containing clamps for fastening the body in space and a dressing device in the form of a power cylinder, the latter having a folding stop bracket with a punch equipped with a balancing mechanism and a latch its working position, the cylinder rod is connected to a supporting self-aligning heel, and its body is fixed on one end by a three-degree hinge e swash sprung horizontal boom unloading unit, the other end of which is pivotally mounted on a bracket secured to the central vertical swivel bearing of the bogie.

 At the same time, the weighing device contains two cylindrical coil springs installed in guides with converging axes perpendicular to the axis of the boom, and the balancing mechanism of the thrust bracket is made in the form of an elastic element connected to the bracket and the housing of the power cylinder.

 The cart is equipped with wheels for movement along the railway track, and the power cylinder is made pneumatic.

 Figure 1 shows a General view of the device; figure 2 is a section aa in figure 1; figure 3 is a section bB in figure 1; figure 4 - section bb in figure 1.

 The device consists of clamps 1 for fastening the body in space, connected to the foundation 2, and a power cylinder 3, on which a folding stop bracket 4 is installed with a punch 5 at the end, a balancing spring 6 and a latch 7. The cylinder rod 3 is connected to a supporting self-aligning fifth 8 and the cylinder 3 itself, by means of a three-stage hinge 9, is fixed at one end of the horizontal swinging boom 10 of the unloading unit 11, and the other end is pivotally mounted on the bracket of the central vertical rotary support 12 mounted on a running carriage 13, the latter having wheels 14 for driving on a railway track.

 The unloading unit 11, in addition, contains two coil springs 15 installed in the guides 16. The cylinder 3 is powered by an air line 17 with a control valve 18. A balancing weight 19 is installed at the end of the boom 10 of the hinge of the support bracket 12.

 The device operates as follows.

 A damaged wagon body is installed in the clamps 1. A trolley 13 is rolled under it. A stop bracket 4 is installed in the working position and fixed in it using the latch 7. The balancing spring 6 facilitates the installation of the bracket 4. The punch 5 is installed on the deformed place of the wagon, pressure is applied air into the cylinder 3. At the same time, the self-aligning heel 8 rests against the foundation 2, and the punch 5 - in the damaged place of the car. The pressure force of the punch 5 and the magnitude of the deformation produced by it are controlled by the valve 18, adjusting the air supply. The three-stage hinge 9 and the swivel bearing 12 allow you to apply forces from different sides, installing the device for editing at different angles and in different places of the bottom of the car.

 In this case, the unloading unit 11 greatly facilitates the manipulation of the dressing device, increases labor productivity.

 The applicant made a prototype device, which fully confirmed the claimed benefits.
