Description

The invention relates to the field of instrumentation technology, and more specifically to devices for determining the maximum allowable angles, inclination of building mechanisms and machines.

Known devices for determining the limiting angles of inclination of an object, the principle of action of which is based on the closure of an electrical circuit with a conductive ball when the Sensor exceeds the permissible angle of inclination Y.

Tilt pointers are known with a metal ball located in the 'chambered chamber of a cylindrical drum, on the inner wall of which the contacts are located in a given angular position. The angle of inclination_ is determined on a scale of £ 2]. . *

Pointers of the critical slope for mobile vehicles are known, based on the same principle, in which 2 braking of the sensing element is provided to reduce the effect of shaking £ 3].

Other contact-type tiltmeters are known with pendulums and signaling devices (4] and [5]. 3

The closest in technical essence and the achieved result to the invention is a device for determining tilt angles of objects, comprising a housing, the bottom of which is made in the form of an annular horizontal platform at the edges and conical in the center, and a sensitive element-ball in contact with tires, isolated from each other, forming a circle and included in the signaling and control circuit drives the alignment mechanisms [b].

The disadvantages of this device are the ability to control only one tilt angle of an object given by the generator of the conical bottom of the device, and the impossibility of determining the value of the final tilt angle of the mechanism at which the device turned on or intermediate between horizontal and maximum allowable tilt angle - limited operating range.

The purpose of the invention is to

expanding the working range when

setting the maximum allowable angle

as well as determining the angle

The goal is achieved by the fact that in a known device comprising a housing made of a dielectric material, a sensitive element is a ball and fixed contacts located on the concave part of the bottom of the body, made as several parts of a circle isolated from each other and included in the signaling and control circuit of the drive of the leveling mechanism, as well as the measuring device, the bottom of the body has the shape of a hemisphere, the fixed contacts are made in the form of electric spirals, each of which is part of the surface of the sphere and has a shape the cone's length along the length, the ball is made magnetic, and at the bottom of the body there is a metal curved rod mounted around the axis of the body, which serves as an electrical contact.

FIG. 1 shows a vertical section of the device; in fig. 2 - its electrical circuit; see 3 shows section A-A in FIG. one.

The device consists of a housing 1 of a dielectric material, the bottom of which is spherical. On the surface of the bottom of the housing 1 are placed electric spirals 2, which are parts of the surface of the sphere, conical in length and isolated from each other, spirals intended to indicate the angle of inclination and the side in which the inclination occurred.

In the lower part of the spherical bottom of the housing 1 there is a horizontal platform on which there is a ball 3, made of steel and magnetized.

On the axis 4, on the one hand, the metal (steel) curved rod 5 is fixed with the possibility of rotation, and on the other hand, the contact nuts 6 for connecting the electric wire.

On top of the housing 1 is hermetically sealed with a cover 7 with a sealing gasket 8. The internal cavity of the housing 1 'is filled with a dielectric fluid.

The number of electric coils 2 is selected depending on the number of definitions of the sides of inclination of the object.

Electrical coils 2 and steel rod 5 with ball 3 are included in the electrical circuits of the drives of the respective alignment mechanisms.

The determination of the angle of inclination of an object is made by finding the relationship between the change in the value of the electrical resistance of the helix 2, on the angle of deflection of the arrow of the electrical device. To do this, it is enough to turn on the measuring device (voltmeter or ammeter) in the electric circuit of the spirals 2 and the rod 5 with the contact ball 3, the scale of which is respectively graduated in degrees.

The operation of the device is as follows.

When the object is in a horizontal position, the ball 3 is located in the lower part of the bottom of the body 1 on a horizontal platform. When the object is tilted, the ball 3 rolls down to one of the side spherical walls of the housing 1 and comes into contact (contact) with one of the electric spirals 2. At the same time, the steel rod 5 as a result of magnetic attraction forces, turns on the axis 4, follows the contact ball 3 and · snugs against its surface. As a result of the contacting surfaces of the electric coils 2 of the contact ball 3 and the steel rod 5, an electrical circuit closes and the electrical signal goes to the measuring device indicating the angle of the object, as well as the alignment of the object.

The indication of the angle of inclination of the object occurs as a result of a change in the electrical resistance of the spirals 2 by moving the contact ball 3 along them.

After alignment of the object, the ball 3 rolls back into the lower part of the bottom of the housing. 1 into a horizontal platform, while the device’s electrical circuit is opened.
