Description

The utility model relates to a hand tool for checking the technical condition of wagons and can be used on railway vehicles to check wheel sets, automatic couplings, measure the side bearings, detect skew and overload of the wagon body, detect malfunction of the axle box assembly and repair of brake equipment.

A hammer is known, comprising a striker and a tail, each of which has impact surfaces, indentations in the form of grooves or recesses, each of which has a width and depth of 0, are made on the impact surface of the hammer, or tail, or on the impact surfaces of both parts. 1 mm to 1 mm. [RU, patent for invention No. 2119866, IPC B25D 1/00, publ. 10.10.1998, author Kalinin V.L. "Hammer"].

The disadvantage of this hammer is its functional unsuitability for use as a hand tool for checking the technical condition of cars.

Known hammer inspector of cars, containing an elongated metal handle, at one end of which a metal shock part is fixed, and a wedge is made at the other end, the shock part is made in the form of a massive nickle on a leg fixed at a distance from the end of the metal handle, while the end forms a pointed part, and on the opposite side of the nickle, a hook is made at the end of the handle. In addition, part of the handle in front of the wedge is made of circular cross section, and the hook section is made rectangular. [RU, patent for invention No. 2409463, IPC B25D 1/00, B25F 1/00 publ. 01/20/2011, author Speshilov N.I. “Hammer of the wagon inspector”].

The disadvantage of this device is that the hammer does not detect wheel pair malfunctions by measuring the thickness of the ridge, identify cracks by means of increased visual inspection, and is also unsuitable for measuring the output of the brake cylinder rod and the wear of brake pads at points for preparing cars for loading and technical fleets service.

This technical solution is selected by the authors as a prototype.

The technical result is to increase operational characteristics and productivity.

The technical result is achieved by the fact that the hammer of the car inspector contains an elongated metal handle, at one end of which a metal shock part is fixed, and at the other end a wedge is made, a shock part made in the form of a massive nickle on a leg fixed at a distance from the end of the metal handle , the end forms a pointed part, and on the opposite side of the nickle at the end of the handle a hook is made, part of the handle in front of the wedge is made of circular cross section, the hook section is made rectangular , according to a utility model, an elongated metal handle after its round part is additionally marked with a metric ruler, from the zero point of the ruler, a metal plate is mounted on the handle, which is made in the form of a parallelepiped, and installed across the handle, one of its smallest sides is rounded, and on the other - a groove of 18 × 25 mm is made and a magnifying glass of tenfold magnification with a protective screen is placed on it in a rubber clip.

The introduction into the hammer of the inspector of cars of the metric line, a metal plate with a groove of 18 × 25 mm and a magnifier of tenfold increase the operational characteristics and productivity of the hammer.

In FIG. 1 is a general view of a hammer of a car inspector.

The hammer of the car inspector consists of an elongated metal handle - 1, a wedge - 2, a massive nickle - 3, legs - 4, a pointed part - 5, a hook - 6, a part of the handle of circular cross section - 7, a metal plate in the shape of a parallelepiped - 8, a groove - 9, magnifiers of tenfold increase in a rubber clip - 10, a protective screen - 11, a metric ruler - 12.

Hammer inspector cars works as follows.

For the maintenance of wagons, all the devices on the hammer are used in the complex: the shock part, made in the form of a massive nickel 3, for high-quality fault detection (end-face mounting) and the work of the axle box of the wagon’s wheel pair, as well as by tapping (in a known manner by the magnitude of the sound when struck by structural elements) to determine the reliability of fastening of the clamps of cars wedge 2 - to detect malfunctions of automatic couplers and closing doors and hatches of the body of freight cars (by moving and swinging wedge 2 in the gaps); pointed part 5 - for breeding cotter pins during installation (by shifting the ends of the cotter pins); hook 6 - to remove the brake lever cotter pins, the brake shoe check, as well as to identify violations of the mechanical fastening of the axle box assembly (by engagement and displacement of structural elements). The presence of the round part 7 of the handle 1 significantly improves working conditions and productivity during maintenance of wagons, and the rectangular cross section of the hook 6 eliminates failures and increases the reliability of the work.

A metal plate in the form of a parallelepiped 8 with a groove 9 plays the role of a template, when installing a hammer on the top of the ridge at a distance of 18 mm from the top of the ridge, the horizontal surface of the groove touches it, which means that the thickness of the ridge is 25 millimeters or less.

To identify the presence of cracks and to increase inspection of parts, a magnifier 10 of tenfold magnification is used, a magnifier 10 is mounted in a rubber cage for shock absorption and has a protective screen 11.

To measure the maximum wear of the brake pads and the output of the stem of the brake cylinder, a metric ruler 12 is used.

All of these operations are performed manually by manipulating the wagon inspector with a hammer.

The proposed hammer inspector cars allows you to:

- control of the maximum wear of the thickness of the ridges of the wheelsets;

- identification of cracks by increased visual inspection;

- control of the output of the rod of the brake cylinder;

- control of the maximum wear of brake pads;

- improving the quality of service for wagons;

- reduction of time spent on maintenance by 15-20%;

- increase productivity by 10-15%.
