SU43219A1 - Instrument for controlling train speed - Google Patents

Description

In the proposed device for controlling the speed of a train, a shaft rotates through an appropriate transmission from the wheel of a locomotive, one end of which is connected to a centrifugal gauge of actual speed, and the other end rotates the drum with a helical groove applied on it, the depth of which is proportional to the required speed on the groove goes the lever connected to the pointer. Both indicators are connected by lever transfers to the device, indicating, at each given moment, the difference between the actual and required speeds and provided with contacts for the sound signal in the presence of the limiting difference between these speeds.

In FIG. 1 is a view of the device from the outside; FIG. 2-circuit diagram of the device; FIG. 3-recorder to record the speed and duration of the train; FIG. 4 and 5 are views in two projections of a longitudinally movable drum coupled with a shaft driven by a wheel of a locomotive.

The proposed device by means of gear / 3 (Fig. 2) is associated with the motion (232)

Schims wheel locomotive. From shchesttern. through a set of interchangeable wheels 9, a gear / 8 and gear 76, rotation is transmitted to the main shaft 9. A drum 8, which is axially movable on the axis / 7, is coupled to the latter, provided along the surface two, for back and forth helical grooves ; the depth of the marked grooves is proportional to the required speed of movement at each given point of the path indicated by the device 7 by means of an appropriate transmission. To determine the actual speed of the train, a centrifugal gauge (/, 2) is designed. Instruments 1 to 2 are connected to the linkage system 7 / and 12 with the indicator 5 of the difference between the actual and the desired speeds at any given moment.

According to the modification of the device, the grooves of the drum 8 are supported by pins 14 and 75 (Fig. 4 and 5), the first of which rests on the groove going ahead and by means of device 7 indicates the previous speed at a distance of 10-15 km. The pin 75 drives the lever 77, and the inclination of the latter shows the technically sound speed of the engine on the way. The difference in the inclination of the gear levers 77 and 72 is the difference between the desired and actual train speeds and is determined by the pointer 5, associated with the levers indicated.

Pointer 3 is provided with contacts a and b for a sound signal about the maximum allowable difference between the actual and the desired speeds.

In order to control the movement of the train, the readings of instrument 7 and 3 are fixed by a self-recording device on the tape moving from the clock mechanism (Fig. 3), with the train moving time t located along the tape length and speed v along the width.

The instrument is equipped with a gear 75 for the purpose of rotating the instrument’s mechanism from hand to accurately position it according to the travel directions and to make changes caused by inaccurate pointing out the instrument.

FIG. Figure 1 shows an external view of the instrument, equipped with indicators 7, 2 and 3 (described above), a distance meter 4 traveled by train from the starting point, a special signal 5, a key b for winding a clock, and a handle 7 from a gear J8 for rotating the mechanism device by hand.

The operation of the instrument is as follows. When the train moves, shaft 9 is rotated from the wheel of a locomotive. The drum 8 coupled to the shaft 9 begins to move in the longitudinal direction. Driving through the screw grooves of the drum 8, the pins 14 and / 5 respectively actuate the indicators 7 and 2 of a given and actual speed.

Pointer 3 gives the difference of these speeds due to the different inclination of the levers 11 vi 12.
