Description

one

The invention relates to the field of instrumentation, in particular, devices for measuring the angles of inclination of objects, the angular orientation of tools, and also as sighting marks when mounting building structures.

The known devices comprise a housing with a sensitive element freely suspended in it, made in the form of a half-disk with a pointer, a reading scale and a housing holder.

The housing and the housing holder for fastening it on the tool (of the mounted structure or apparatus) are rigidly interconnected, which prevents the device from being used for additional orientation of the tool (structure, apparatus) in a plane perpendicular to the half-disk rotation plane.

The proposed device is characterized in that it is provided with an additional reading scale, made in the form of two half-arcs, pivotally connected to the case holder, also connected by a hinge with the axis of the half disk, has a C-shape.

FIG. 1 shows a device in a plane aligned with the plane of the vrash, of a miniature half disk, index; in fig. 2 - in. the plane combined with the plane of the reference position of the additional scale, i.e.

in a plane perpendicular to the plane of the vrash, half a disk; in fig. 3 is a view along arrow A in FIG. 1. The thin solid lines in FIG. 1 shows the position of the device when it is tilted by an angle a in the plane of the vras, of the tilting half-disk indicator and in FIG. 2 - when tilted by an angle p in the plane perpendicular to the vrash section of the plane, there is a half-disk indicator.

The device includes a housing 1 with a holder 2, a scale 3 and a cylindrical opening 4 in which the hinge 5 is fixed to an anchor half-disk index 6, made with diametrically located relative to

it has an arrow 7. On the outer side of the housing 1 there are additional arrow-pointer 8, scale 9 and hinge 10 with axle 11 and swivel holder 12. Axle 11 is aligned with the half-disk plane of rotation 6. Holder 12

The C-axis 13 is rigidly connected to the axis 14 of rotation of the half-disk 6, and the holder 12 is C-shaped axis 13 is rigidly connected to the axis 14 of the rotation of the half-disk 6. Scale 9 is made in the form

noBOpOTHBix half-arrays 15 and 16 pivotally connected to the holder. 2 liters located on two sides with respect to non-OO. The semi-arrays 15 and 1-6 and A-OSU-13 in the working reference position are placed in a plane perpendicular to the plane of rotation of the half-disk 6, i.e. in the rotation axis of axis-13. For the mounting device, for example, on the device being mounted, the holes 17 serve, and for fixing the half-arcs 15 and 16 in the non-working position and in the position of counting there are used clamps corresponding to 18 and 19. The device operates as follows.

The device is fixed on the device to be mounted, aligning the plane of control of the installation slopes of the device with mutually perpendicular reading planes of pins 3 and 9. Fix the device on the device in a place accessible for observation by optical devices (optical instruments not shown). When the tilt of the apparatus is mounted, its angles of inclination are determined by the sight of optical instruments on the directional arrows 7 and 8 and the scales 3 and 9.
