SU1208481A1 - Arrangement for recording movement parameters of mine hoist vessels - Google Patents

Description

The invention relates to the equipment of mine hoisting installations, in particular to the means of controlling the parameters of the movement of vessels in the vessel.

The purpose of the invention is to improve the accuracy of measuring the position of vessels in a shaft.

The drawing shows the device, a general view.

In Kopni ce 1, there is a tape-testing mechanism 2, rewinding at a constant speed. Tape 3, on which a millimeter-scale grid is applied by the printing method. The recorder A is placed on the carriage 5 and provided with a track marker 6 and a speed recorder 7 positioned relative to the carriage with the possibility of recording along the tape 3 in the direction of the arrow 8. Timer 9 is placed outside the carriage stationary relative to the housing 1, with the possibility of recording along and across the tape 3 in the direction of the arrow 10, while it is placed on the same line 11 with the marker 6 and the CKOpig cTH 7 recorder in its neutral position.

The carriage 5 is made with the possibility of reciprocating movement in the transverse direction relative to the ribbon 3 along the guides 12 and is provided with a drive 13, kinematically connected to a reversible electric motor 4, which is connected to the amplifier and the signal converter 16 by means of an electrical circuit 15 17, made in the form of selsyn. The gear ratio of the drive 13 of the carriage 5 is chosen so that when it is reciprocating, it overlaps with a track marker the working field of the tape 3 across its entire width, except for the free fields & and sex) of the time record, where the scale of the path is determined by the formula

The proposed device works as follows.

In the initial position, for example, the vessel is in its lowest position - in the load. A tape of 3 s — a constant speed with the help of a treadmill mechanism 2 moves in the direction of the arrow 20. In addition to the tape with a printed grid applied by a printing grid, clean roll paper can be used. During the technological pauses and stops of the ascent, the track marker and the speed register register the straight line 21, and the time marker is drawn 22, respectively, along the belt. Scale units of time, paths and speeds are entered in the instrument passport. If the timer has gone out of order, the time interval of interest is calculated by the formula

 V

where C is the segment of length, measured along the tape, between two events divided by a time interval. When the lifting machine is in operation, the vessel starts to rise, the tachogenerator connected to the machine shaft turns on the emf and triggers the speed recorder, while the deviation of the speed line from the baseline of the path is proportional to the value of the emf and, therefore, the speed of the vessel. At the same time, the tracking system for the position of the vessel, containing the sensor path 17 in the form of a selsyn, generates signals corresponding to its actual position in the trunk. These signals are sent to the amplifier and converter 16, from where, via electric circuit 15, power is supplied to the electric motor 14 “Through the drive 3 from the electric motor 14, movement

It is transmitted to the carriage 5, which moves along the guides 12, and its actual position within the working field O of the recording path strictly corresponds to the actual position of the vessel in the barrel between the extreme lower and upper points. Moving the carriage fixes the track marker 6 on the tape in the form of line 23. At the same time, the speed marker 7 draws its (Curve) line 24. The vessel lifting height from the lower end position can be easily determined by the distance a measured on the tape in the direction parallel to the arrow ten

10 and time. In other words, at any point in time, it is possible to reliably say where the vessel was in the barrel and what speed it had, in doing so. In addition, the direction of movement of the vessel is easily understood, since the movement of the vessel from the bottom up corresponds to the direction of the line of the path from left to right, and from top to bottom the direction of the path from left to right corresponds to the line of time in the first and second quadrants.,
