SU38787A1 - Automatic Level - Google Patents

Description

The author's certificate No. 19799 describes an automatic level using a rotating gyroscopic mass, in which the mass axis carries a jagged arc, which serves to transmit mass deviations in relation to the frame suspended from the wagon through a gear rack and worm gear that records the height difference on a cylinder driven by a corresponding gear from the drive wheel of a wagon.

In the modified automatic level now proposed, the gear arc serves as a gear arc, which is pivotally connected with a fork to activate the clutch, which carries the gear, which in turn serves to activate the corresponding mechanism that drives the barant along the axis of rotation for fixing on the drum pencil slopes of the path.

In the schematic drawing of FIG. 1 shows a side view of the level and FIG. 2 is a view from above of the gyroscopic mass of the frame.

. (283)

The gyroscopic mass I is fixed on the axis 2 with an electric motor 3 mounted on it, forming a primary body and serving to rotate the mass; rods 4.4 hold the stator of the motor away from rotation. The gyroscopic mass 1 is covered by a fork 5 with a counterweight 6 and a gear arc 7 coupled to the gear 8, on one axis with which sits the gear 9, engulfed by the gear fork 10, which can engage its upper or lower half with the gear 9. The fork 10 is hingedly fastened to the fork 12, which serves for the longitudinal movement of the disks 13 and 14 and for the friction locking of the coupling parts 15-16. The disk 13 has a friction clutch with a rubber cone 17, mounted on the same axis with the gear 18, which is coupled with the conical gear 19, mounted on the axis 20, equipped with a gear sleeve 21 with the drum mounted on it 22. Napple grafted paper on the drum A recording is made of a quarantine 23, mounted in the frame 24 of the wagon.

The movable part 16, of the friction clutch rigidly connected to the disk 14, engages in engagement with the part 15.

Coupling by the spring 25, is included in the flooded 12 for Zolovka 26, Disk I has a “rubber grip with a rubber cone 27, two bevel gears are mounted on the same axle 28 with the keeper: IS and 30, which can be simultaneously connected with the bevel gear 31, nasa Jenasn Yao H732 "; 1" and at the end of the Ap; which is a march 33. Lastly, it is closed with a cantilee gear 34, mounted on an axis 35, the other end is equipped with gear 36 interlocked with a gear sleeve 21.

Between the two vertical bars 37 of the frame is placed a roller 38, equipped with a cam 39, a lever 40 and a crank 41; 40 touches a protrusion 42 on a gear arc 7. The crank 41 is connected with a lever 44 to the lever 44, which provides longitudinal movement along the axis 28 of the bevel gears 29 and 30 to alternately grip them with the gear 31, Axis 45, carrying the disk 13, This is done through the gear 46 and 47 and the shaft 48 with the trolley's undercarriage. The frame 24 is suspended using the protrusions 32 and 33 of the special trolley in the shape of a bicycle, which are located on its two straightaway kandas.

The cody trolley moves on a horizontal surface of the earth, a small carriage with a mass of 1 mass is in the neutral position and at this time the fork 10 is in the rightmost position (in the drawing); having parted the clutches 15 and 16, and the drum does not move along axis 20, but rotates with it, the winding wheel of the cart rotates and transfers the roller 48 coupled to it, the conical gears 47 and 46, the axis 45, the disk 13, the rubber the cone 17, the gear wheels 18, 19, the axis 20 and, finally, the drum 22. At the same time, the pencil 23 draws horizontal lHHJO on paper.

as the terrain changes, for example, up; e, the end 33 of the rrm rises relative to the end 32. The frame 5 associated with the gyroscopic mass maintains the horizontal position in this causes the gear 8 to rotate. This dvigier 1g is transmitted from gear 9 and from the top of the toothed part to Lk 10,

The cutter is included in the STE, 1E with a tooth of CH2 due to this, the point of shash% 12. 7 turned the lever 40 out of the way, the roller 38 turned), the chuck 39 went down and at the same time turned on the upper part of the fork 10, The latter moves to the left (in the drawing) and p 18 - psh1 "etra w etsr tShe net the ratio of the number of revolutions of the drum 22 to the number of revolutions of the drive wheel. At the same number of revolutions of the latter, the drum is rotated smaller and thereby preserves the actual size of the laying of the inclined path drawn on the graph,

In the frame end 33 of the frame, the fork 12 releases the movable part 16 of the coupling and under the action of the spring 25 it engages the coupling part 15 and with the axis 45 and begins to rotate. The decrease is transmitted to the disk 14, the sonus, 27, the axis 28, the conical gear 29, 30, 31, axes 32, conical gears 33, 34, axis 35, gear 36 and rail 21, which displaces the drum 31 along its axis, as a result of which the pencil draws an inclined line, and with increasing lift the drum moves more steadily along the axis line.

During the descent, when the end 33 is below the end 32, the crank 41, under the action of the roller 38, transmits motion through the pull 43 to roar, 44, which switches the comic teeth 29, 30 and thereby changes the direction of rotation of the drum. The latter begins to shift along (Lee in the opposite direction and the pencil draws descending lines on the drum.

In this way, the profile of the passable path is drawn on the drum paper.

subject matter

The type of automatic automatic recording described in the author's certificate No. 19799 is characterized by the use of a gear fork 10 coupled by means of teeth 8 and 9 with gear Luga 7, which serves for irregular gyroscope 1 k

its core is tied to a fork. 12, intended to be turned on 16, carrying a disk 14, serving to turn on an appropriate tamper wheel intended to overturn the drum 22 along the axis of rotation 20 for the purpose of fixing on 6; the slope of the quarantine 23 slopes of the track.
