Description

The invention relates to a hand tool for checking the technical condition of wagons and can be used to check the automatic coupler, measure the side bearings, detect skew and overload of the wagon body, detect malfunction of the axle box and repair brake equipment.

Known hammer, including the tail part in the form of a handle and the shock part (RF Patent No. 2119866, class B25D 1/00, publ. 10.10.1998).

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

The closest in technical essence and the achieved result is a car inspector hammer containing an elongated metal handle, a metal shock part is fixed at one end and a wedge is made at the other end (RF Patent Application No. 96109440, class B25D 1/00, publ. 08/10/1998).

A disadvantage of the known device is that the hammer does not allow to detect malfunction of the axle box, to detect cracks in the wheelset by tapping, and is also unsuitable for repairing brake equipment at the points of preparation of cars for loading and maintenance parks.

The technical problem to which the invention is directed is to increase the level of quality of service for wagons, reduce the time spent on maintenance and increase productivity.

The solution to this problem is achieved by the fact that the hammer of the car inspector, 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, according to the invention has 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, 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. In addition, the hook section is rectangular.

The manufacture of the shock part in the form of a massive nickle on a leg fixed at a distance from the end of the metal handle allows high-quality detection of malfunction of the axle box and repair of brake equipment due to tapping.

The execution of the end of the handle with the pointed part allows you to breed cotter pins when they are installed in the carriage equipment.

Execution at the end of the handle of the hook allows you to remove the cotter pins of the brake levers, the check of the brake shoes, to reveal a violation of the mechanical fastening of the axle box assembly.

The manufacture of a part of the handle in front of a round wedge increases the usability of the tool and eliminates damage to the hand.

Performing a rectangular cross-section of the hook increases its strength, reliability in operation and simplifies the manufacturing technology of the wagon inspector's hammer.

The invention is illustrated in the drawing.

Figure 1 shows a General view of the hammer inspector cars, front view; figure 2 is the same, a top view; figure 3 is the same side view; figure 4 is a section aa in figure 2.

The hammer of the car inspector contains an elongated metal handle 1, at one end of which a metal shock part is fixed, and a wedge 2 is made at the other end. The shock part is made in the form of a massive nickel 3 on a leg 4, fixed at a distance from the end of the metal handle 1, while the end forms a pointed part 5, and on the opposite side of the nickle 3 at the end of the handle is a hook 6. Part 7 of the handle 1 in front of the wedge 2 is made of circular cross section. The cross section of the hook 6 is made rectangular.

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, is used for high-quality fault detection (end-face fixing) and the work of the axle box of the wagon 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 the fastening of the clamps of cars; wedge 2 - to detect malfunctions of automatic couplings 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). All these operations are carried out manually by manipulating the wagon inspector with a hammer, while the presence of the round part 7 of the handle 1 significantly improves working conditions and productivity during the maintenance of wagons, and the rectangular section of the hook 6 eliminates failures and increases the reliability of operation.

Unlike analogues, this design of the car inspector's hammer has an increased level of quality of car service, reduces the time spent on maintenance and increases productivity.
