The invention relates to a mine hoist and is intended to record the main parameters of the mine hoist operation, characterizing its pre-emergency and post-emergency condition.

The purpose of the invention is to increase the reliability of a device for recording parameters of a mine lifting installation.

The drawing shows a functional diagram of the device.

The device comprises a pulse sensor 1 for moving a lifting vessel connected to the shaft 2 of the lifting installation. One output of the displacement sensor 1 is connected to the node 3 recognition of the direction of movement, and the other to the counting inputs of the summing 4 and reverse 5 counters, outputs 6 and 7 of the recognition node 3

directions of motion are connected to other inputs of the counter 5 counter. The digital outputs of the summing 4 and reverse 5 counters, the outputs 6 and 7 of the node 3 for recognizing the direction of movement and bus 8 of discrete information about the state of the installation nodes (control signals, the status of the most important protection devices, etc.) are connected to the inputs of the first register 9 storage, and its outputs with the corresponding information inputs of the second storage register 10, the bit inputs of the columns of the matrix storage unit 11 and the first inputs of the comparison unit 12, with the second inputs of which the outputs of the second register 10 are connected and, the output of the comparison unit 12 is connected to the recording enable inputs of the second register 10, the matrix storage unit 11, and block XI

ka 13 control the ring counter I. Clock generator 15, the output of which is connected to the inputs of the driver 16 of the signals on the front and the driver 17 of the signals on the trailing edge of the clock. Tires 18 are for recording the time of day.

The source of discrete information about the movement of the lifting vessel and speed is the sensor 1, which receives rotation from the shaft 2 of the lifting installation. The motion direction recognizing unit 3 provides switching of the outputs b and 7 of the direction of motion in accordance with the direction of motion of the lifting vessels. Pulses from the sensor 1 are supplied to the counting inputs of the summing 4 and 5 reversing counters. The reversible 5 counter is reset to zero every time one of the vessels is in one of the extreme positions taken as the starting point (a reset unit is not shown in the diagram). The number of pulses / counted by a summing 4 counter, during the time between the trailing edge of the previous clock pulse, when there is a reset to zero and the leading edge of the next clock pulse, when recording in the first register 9 is proportional to the speed of rise.

The generator 15 clock pulses at the moment of passing the leading edge of each pulse records in the first register 9 the speed code from the summing 4 counters, the location code of the lifting vessel from the reversible 5 counter, information about the direction of movement of the lifting vessels (outputs 6 and 7) and information from buses 8 characterizing other lifting parameters. Information from the outputs of the first register 9 is fed to the digital inputs of the matrix storage unit 11 and to the first inputs of the comparison unit 12, the second inputs of which receive information from the second register 10, when the information at these inputs differs, the comparison unit 12 generates a pulse for recording information from the outputs of the first register 9 to the second register 10 and the matrix storage unit 11, the control unit 13 is prepared.

At the moment the trailing edge of the clock pulse passes, the totalizing 4 counters are reset to zero and, when the control unit 13 is ready, they advance to the unit of the ring counter 14, whereby the next line of the matrix storage unit 11 is prepared for information reception.

With the equality of information codes on the first and second inputs of block 12 comparison

pulse generation does not occur, information is recorded in the second register 10 and the matrix storage unit is not produced, the state of the ring counter 14 does not change.

Information is recorded only if at least one of the recorded operating parameters of the mine lifting installation changes, i.e. a reduction in the volume of the matrix storage unit and an increase in the reliability of the device for registering the parameters of the lifting installation are achieved.
