Description

(54) OBJECT TILT SHUTTER OBJECT

I

The invention relates to devices for automatically controlling the angle of inclination of objects, such as pile masts, piling, aggregates and drilling equipment.

Known tilt angle sensors with a sensitive element in the form of an attendant, are known as a contact device for receiving a signal when the sensitive element l is deflected.

However, in these nacron angle sensors

There are contact devices that reduce accuracy, robustness and reduce the durability of sensors. The devices contain fire switches mounted on adjustable brackets on the oscillation trajectory.

Also known tilt angle sensors with contactless npSi. Blowers, for example with photoelectric, with inductively coupled coils, included in the circuit of the auto-generator. However, such sensors have relatively little sensitivity to small angles of inclination or are complex in design and unsuitable for use in severe production conditions 2,

The closest in technical essence to the present invention is a tilt angle sensor containing a sensing element. Mair-type and contactless transducer, made in the form of sealed magnetic contacts, laid out which is determined by the magnitude of the limiting angle of inclination Z.

However, the use of such converters with varying voltage supply, ambient temperature, the presence of vibration, shock is undesirable.

The purpose of the invention is to simplify the first construction, increased reliability and durability of the angle sensor.

For this, in the proposed sensor there is a non-contact slit-type end switch: mounted-on the holder in the sensor case so that the slit plane is with the horizontal plane an angle equal to the limiting angle of inclination, and the switching disk is perpendicular to it. the center of the disk is aligned with the axis of the suspension (magnet. The dimensions of the tandem and the switching metal disk are selected in accordance with the geometrical dimensions of the slots of the proximity switches. When the deviation is From the vertical position, the metal disk enters the slit of the contactless switch. The switches are mounted on holders having a common center at the point of suspension of the tangent, so that the plane of the shepe makes an angle with the horizontal plane equal to the limiting angle of inclination. tilt angles the holders are mounted for movement along the guides in the sensor housing. The drawing shows the basic diagram of the tilt angle sensor. The sensor contains a sensitive element in the form of a tandem 11, a switching metal disc 2 mounted perpendicular to its axis perpendicular to its axis, non-contact switches 3 of a slot type, movably fixed in the housing 4 on the holders 5 capable of moving inside the housing depending on the received limit tilt angle. To reduce the free oscillations of tm 1, various damping devices can be used. The sensor works as follows. Contactless switches 3 are mounted by holders 5 moving in housing 4 in a position corresponding to the limiting angle of inclination. When deviating 1 from the vertical position to the limiting angle, the switching metal disk 2 enters the gap of the contactless switch 3, which operates and generates an electrical signal. When the master 1 returns to the vertical position, the switching metal disc 2 leaves the slot of the contactless switch 3 and the electric signal is detectable. DETAILED DESCRIPTION OF THE INVENTION Claims of an angle of inclination i of an object, comprising a housing, a sensitive element of the type, projectile angles of inclination in the form of end switches, characterized in that, in order to simplify the design and increase reliability, the non-contact end switch of the slot type is mounted on the sensor body in such a way that the slit flatness makes an angle with the horizontal plane equal to the limiting angle of inclination, and the metal disk switching it is fixed to the perpendicular to o to its axis, with the center of the disk aligned with the axis of the suspension of the tandem.
