Description

(54) УСТРОЙСТВО ДЛЯ ИЗМЕРЕНИЯ ВЕЛИЧИНЫ ДАВЛЕНИЯ КОЛЕСА ЖЕЛЕЗНОДОРОЖНОГО ВАГОНА(54) DEVICE FOR MEASURING THE VALUE OF PRESSURE OF THE WHEEL OF A RAILWAY CAR

чатый конец, который крепитс к квадратным шпилькам 15 вала 5.The cable end, which is attached to the square studs 15 of the shaft 5.

Измерение производитс следующим образом .The measurement is carried out as follows.

Устройство устанавливают так, что основание 3 опоры располагаетс непосредственно на подошве 17 рельсы или, как показано, с помощью плиты 18. Когда рычаг 16 находитс в конечном положении (в данном случае это верхнее положение), а скобы 1 со втулкой 2 - в нижнем положении, то нужно, как правило, чтобы опорна кромка 19, наход ща с на верхнем конце скобы 1, располагалась бы на поверхности контакта обода колеса 20 или достаточно близко от нее. Начина из этого положени , вручную поворачивают рычаг 16, в результате чего происход т постепенный подъем втулки 2 и деформаци скобы 1, котора зависит от нагрузки, создаваемой колесом 20. Величина этой нагрузки отмечаетс на индикаторе 10, щуп которого движетс в соответствии с перемещением рычага 16, показывающим непрерывное увеличение нагрузки до того момента, когда произойдет отделение колеса от рельса, и индикатор зафиксирует величину определ емой нагрузки.The device is mounted so that the base 3 of the support is located directly on the sole 17 of the rails or, as shown, with the help of the plate 18. When the lever 16 is in the final position (in this case, this is the upper position), and the bracket 1 with the sleeve 2 is in the lower position It is then necessary, as a rule, that the supporting edge 19, located at the upper end of the clevis 1, be located on or close enough to the contact surface of the rim of the wheel 20. Starting from this position, the lever 16 is manually rotated, resulting in a gradual lifting of the sleeve 2 and deformation of the bracket 1, which depends on the load caused by the wheel 20. The magnitude of this load is indicated on the indicator 10, the probe of which moves in accordance with the movement of the lever 16 , showing a continuous increase in load until the moment when the wheel separates from the rail, and the indicator will record the value of the load being determined.

При помощи описываемого устройства можно производить измерени с повышенной точностью . При этом затрачиваетс значительно меньше времени, и нет необходимости в больщом количестве рабочей силы и сложных операци х. Кроме того, устройство малогабаритно , недорого и легко транспортируетс с одного места на другое.Using the described device, measurements can be made with increased accuracy. At the same time, much less time is spent, and there is no need for a large amount of labor and complex operations. In addition, the device is small, inexpensive, and easily transported from one place to another.

Claims

Invention Formula

A device for measuring the pressure of a railcar wheel wheel on rails, comprising a base, a weighing device, a lever with a handle for raising the wheel of a railroad car, and an indicator that, in order to simplify and reduce the cost of construction, the ux-shaped device elastically deformable bracket, on the inner side of its lower part a sleeve is attached, eccentrically mounted on a shaft fixed in racks of an U-shaped support; at the ends of the shaft a lever with a handle for raising the wheel is strengthened; Inside the U-shaped bracket there is a rocker clamped by a spring between two pointed supports, one of which is located on the inner side of the upper part of the bracket and the second on the upper part of the sleeve, the free end of the rocker arm rests on the indicator probe installed on the outer side of the upper part of U- shaped bracket.

2. A device according to claim 1, characterized in that a support edge is installed on the outer side of the upper part of the U-shaped bracket, made, for example, in the form of a segment of a circle. U ,, ::.
