Description

The utility model relates to railway transport, and in particular to the design of devices for mounting the boiler of a tank car on a frame.

A device for mounting a boiler of a tank car on a frame containing a clamp, each end of which is connected to the coupling bolts provided with clamps, Russian patent No. 2207260, B61D 5/00, publ. 06/27/2003 (prototype).

The technical problem inherent in this device is the low reliability due to the lack of tools that increase the stiffness of the twisting ends of the clamp when fixing the clamp on the boiler of the tank car using mounting nuts.

The technical result of the claimed utility model is to increase the reliability of the device for mounting the boiler of the tank car on the frame.

The claimed technical result is achieved by a device for fastening the boiler of a tank car on a frame containing a clamp, each end of which is rigidly connected to a corresponding coupling bolt provided with a clamp, the clamp is made in the form of a curved L-shaped plate, the upper end of which is fixed using clamping plates on the clamp, at the lower end of the L-shaped plate, bent in the form of a shelf, a through hole is made through which the said coupling bolt is passed, the clamping plates are interconnected threaded elements passed through through holes made in the pressure plates.

The inventive utility model differs from the prototype in that the latch is made in the form of a curved L-shaped plate, the upper end of which is tightly fixed to the clamp using clamping plates, a through hole is made in the lower end of the L-shaped plate, bent in the form of a shelf, through which said coupling bolt is passed, the pressure plates are interconnected by threaded elements passed through through holes made in the pressure plates. Such differences from the prototype give reason to assert that the proposed technical solution meets the patentability criterion of a utility model - “novelty”.

The claimed invention is represented by illustrations, where:

in FIG. 1 - part of the tank car, with a device for mounting the boiler on the frame;

in FIG. 2 - a device for mounting the boiler on the frame, the remaining elements of the tank car are conventionally not shown.

A device for mounting the boiler of a tank car on a supporting frame, contains a clamp 1 (Fig. 1), each end of which is connected by welding seams to the tie bolts 2. The tie bolts 2 are provided with clamps. The latches are made in the form of curved plates 3 L-shaped (Fig. 2). The upper end 3.1 of the curved plate 3 with the help of the fixing element is rigidly fixed to the clamp 1. In the lower end of the curved plate 3, made in the form of a shelf 3.2, a through hole 3.3 is made. In the specified through hole 3.3 posted by the coupling bolt 2.

The locking element is made in the form of clamping pads 4, fixing the plate 3 on the clamp 1. The clamping pads 4 are interconnected by threaded elements 5, passed through through holes made at the ends of the clamping pads 4. As the threaded elements 5 can be used bolts, screws, nuts locked with washers.

The ends of the clamp 1 are fixed with mounting nuts 6.

A utility model is used as follows.

The clamp 1 is designed to be fixed on the supporting frame 7 of the tank car. The ends of the clamp 1 are connected to the tie bolts 2 using welding seams. Clamping bolts 2 clamp 1 is connected to the frame 7 of the tank car.

During operation, the clamp 1 is subjected to high dynamic loads, causing high internal stresses in it. When installing the clamp 1 on the boiler 8 of the tank car, tighten the mounting nuts 6. In this case, the middle part of the clamp 1, in contact with the outer surface of the boiler 8, is pressed against the outer surface of the boiler 8 under the action of the pulling force developed by the mounting nuts 6, excluding thus, twisting the middle part of the clamp 1 during rotation of the mounting nuts 6.

To increase the torsional rigidity of the free ends of the clamp 1 and increase the reliability of the device, a latch is proposed in the form of a curved plate 3 of an L-shape. The longitudinal cross-section of the L-shaped plate 3 adds an additional value to the total cross-sectional area of the end of the clamp 1 and the L-shaped plate 3, increasing the total stiffness on the twisting of the ends of the clamp 1. If necessary, to further increase the stiffness on the twisting of the ends of the clamp 1 additional fixing of the shelf 3.2 of the plate 3 of the L-shaped to the shaft of the coupling bolt 2 by welding.

The pressure pads 4, fixing the upper ends 3.1 of the plate 3 on the clamp 1, increase the reliability of the device for mounting the boiler 8 of the tank car on the frame 7.
