Description

There are automatic instruments for measuring the length of the projection of the distance traveled with the projection length counter and with a plumb for changing the gear to the counter corresponding to the change in the length of the projection of the path depending on the angle of the terrain. In the proposed device for changing the rotation of the shaft carrying the counter, depending on the slope of the terrain, a movable pulley of variable diameter connected with a plumb, received rotation from the traveling wheel through a flexible transmission, is used to guide a roller driven by a spring.

In the schematic drawing of FIG. 1 is a side view of the device; FIG. 2 - view it from the end; FIG. 3 is a side view of a device with a roller for guiding flexible transmission; FIG. 4 is a front view.

To the frame supported by the wheels / (Fig. 1), two pillars 3 are attached with stops 2. In the sub-supports of the pillars, a beam 4 is inserted, carrying a rack 6, to which a plumb line 5 is loaded with an end weight of about 16 kg. With the help of tg 7 and 12, of which the latter passes along the axis of the trunnion of the beam 4, the plumb line 5 is associated with the clevis 13, carrying the pulley 14 of variable diameter. Pulley round flexible connection 8

(Fig. 1, 3), the envelope is also the wheel 22, driven in rotation from the wheel 19 through the shaft 23 of the transmission 18.

The bracket 13 and the pulley 14 are mounted on the shaft 16, provided with a key so that the pulley has the ability to move along the shaft, however, during its rotation, the shaft 16 rotates; In order for the bracket not to be rotated by it while moving along the shaft, its ends are provided with bushings that rotate in the bracket along with the shaft. The shaft 16 through the transfer of 21 coupled with the counter.

When moving the device on a horizontal surface, the flexible link 8 bends around the pulley 14 at its smallest diameter equal to the diameter of the wheel 22. When the device is moved on an inclined surface, the plumb bob .5 remaining vertical moves the yoke 13 and the pulley 14 with it, so that the transfer starts to bend around the pulley over its larger diameter}, as a result of which, with the same displacement of the device, the counter, making a smaller number of revolutions, shows the magnitude of the projected path.

In order to guide the flexible link 8 along the pulley 14 and, regardless of the size of the diameter over which it goes around the pulley, this flexible gear was all tightly tensioned, the roller 15 was used (Figs. 2, 3, 4) under the impact of the spring 77; Such a device has the purpose to ensure that with the longitudinal movement of the pulley 14, the flexible transmission remains all the time in the plane of the roller 75 and all the time is pressed against the pulley.

The subject matter of the invention.
