Description

one

The invention relates to surveying geodetic instruments and is intended for geometric leveling by a horizontal beam and for measuring and setting slopes in the construction and control of roads, mainly in mining enterprises (quarries, mines).

Known levels-inclinometers containing telescopes of the leveling and inclinometer branches, prism reversing systems, a lens compensator-inclinometer with a microscope, alignment, focusing and switching devices. However, the optical system of this leveling inclinometer is complex, does not allow for automatic stabilization of the sighting directions, and does not provide free maneuvering by the field of view of the leveling and inclinometer parts of the device.

The purpose of the invention is to provide synchronous self-installation of the lines of sight of the leveling and inclining-meter branches of the device, as well as the simultaneous or sequential inclusion of their fields of view.

In order to achieve this goal, the self-alignment of the sighting directions of the leveling and inclinometer arms of the device is carried out by one block consisting of two right-angle prisms, which together with two other prisms make up

Porro I kind. The switching of the visual fields in the common eye is performed by an optical unit consisting of two contiguous rhombic prisms. Such a device for switching fields of view allows switching both branches of the device to work alternately (sequentially) or to see the images given by the leveling and inclinometer branches simultaneously (synchronously) according to the principle of a divided double image.

The drawing schematically shows the proposed level-inclinometer, side and top views.

The device consists of two main parts: the leveling branch, which includes lens 1, wraps the prism system 2-3 and diamond prism 4, and the inclinometer branch, which includes a lens inclinometer compensator 5-6, lens 7, identical to the lens /, prism turning system 8-9, identical to a prism system 2-3, and a diamond prism 10, identical to a diamond prism 4. The image of lenses is formed by lenses in the plane of the reticle 11 and viewed through a common eye for both branches 12. The inclination compensator, one of the lenses of which ( NLA 6} has the ability to move up and down, and comprises an index schkalu linear type, a graded slopes (thousandths of fraction x distance), which is read through the microscope 13.

In order to simultaneously automatically stabilize the sighting lines belonging to both branches of the instrument, prisms 5 and 9 are combined in a common unit, freely suspended as a tiller on the horizontal axis 14 perpendicular to the direction of sight. The focusing of both branches of the device is carried out by moving along the direction of sighting of the prism block 2-8 or the stabilized prism block 3-9.

The prism block 4-10 is configured to move perpendicular to the direction of sight, the inner contact edges of the prisms are located close to each other so that they form a thin vertical dividing line 15. In the extreme positions (right, left) of block 4-10 you can observe completely or the field of view of the level, or the field of view of the inclinometer (in the drawing, block 4-10 is depicted in a position where the field of the support is completely formed by the objective 1 of the leveling branch). In the intermediate positions, it is possible to observe simultaneously in different ratios both the field of view formed by the leveling branch and the field of view related to the inclinometer branch.

The adjustment of the inclinometer branch of the device is carried out by means of elements of the compensator 5-6, the alignment of the leveling branch - by the optical wedge 16, which covers the lens inlet opening /.

When the device operates in the leveling mode, the prism unit of 4-10 switches is set to the extreme right position, opening the field of view of the leveling branch. The installation operations and sampling on the rail are performed in the usual geometric alignment order.

When the device is operating in the inclinometer mode, the prism unit 4-10 is set to the extreme left position, and on the inclinometer scale (moving lens 6) the specified inclination is recorded by the microscope 13. If necessary, measure the existing incline with the help of shifts of the compensator lens 6, the inclinometer sight line is directed at the tool height, counting this height on the leveling rail installed on the observer section of the road. If it is necessary to take readings simultaneously on the level and the inclinometer, the prism block 4-10 is placed in an intermediate position.

Subject invention

1. A level inclinometer containing telescopes of the leveling and inclining branches with a common eye and a grid of threads, prism reversing systems, a lens compensator inclinometer with a microscope, an alignment wedge, focusing and switching devices, different in that in order to ensure synchronous self-installation lines of sight of the leveling and incidence of instrument branches, as well as simultaneous or sequential switching on of the fields of view of the leveling and inclinometer branches, in it the prisms of the inverting systems are suspended for one oh the same horizontal axis in a common block mounted for movement in the direction of sighting, and in front of the grid of threads there is a block of rhombic prisms that move perpendicular to the direction of sighting, and the contacting edges of rhombic prisms form the line of separation of the visual fields.
