Description

one

The invention relates to devices for the operative control of the operation mode of a system of technologically connected conveyors, for example, conveyors of a complex of mining equipment of continuous action, including a rotary or chain excavator, conveyor transport and a spreader.

Devices are known for controlling the mode of operation of a system of series-connected conveyors. These devices contain either a performance meter of the initial conveyor of the system with a corresponding indicator, according to the indications of which the operation of the whole conveyor system is judged, or a mnemonic diagram consisting of illuminated strip-sections including the ori- gation of individual conveyors.

However, in such devices, the degree of loading of the Conveyor with the transported material is measured by a performance sensor in a very short section of the conveyor (about 1 meter), while the length of all conveyors of the complex is several kilometers (often up to 10 km). As a result, taking into account the inevitable fluctuations in productivity and lereryv in the supply of material, according to the indications of the indicator of the gauge of the productivity of the manual kojpzeeyer it is impossible to judge at a time about the stop of the load, the distribution of the material along the length and process

transportation of material by all conveyors. In addition, the indication of the operation of the conveyors by turning on the constant illumination of the section of the mimic when starting the corresponding conveyor, regardless of the amount of material distribution along the conveyors, does not provide information about the process of passing and defining the material along each of the conveyors.

as such information is very necessary for the operational control of the mode of operating conveyors.

The purpose of the invention is to develop a device that provides an indication of the process of passing the transported material along each of the conveyors in the form of a moving image, reflecting the amount and distribution of the material along the conveyors. This is achieved by controlling nodes.

the speeds of the conveyors are connected to the shift inputs of the corresponding sections of the register, and the outputs of each section of the register are connected to the corresponding section of the mnemonic scheme.

Fla drawing is represented by f y cd and it is flax ;:

scheme of the device for monitoring the mode of operation of conveyors.

The initial conveyor 1 of the conveyor system (including the conveyors 2, 3) is equipped with a frequency sensor 4

nodes are installed on each conveyor

5, 6, 7 controls the speed of the tape with frequency output slots, for example, synchronous technogenerators.

The sensor 4 of the performance of the initial conveyor 1 is connected to the main input 8 of the register, consisting of sections 9, 10, I. Nodes 5, 6, 7 of the control of the speed of movement of the individual conveyors are connected to the shift inputs 12, 13, 14 of sections 9, 10, 11 sequential register. Outputs of 15 cells of each register section are connected to sections Ii6, 17, 18 of the mimic corresponding to conveyors 1, 2, 3 systems of technologically connected conveyors.

The device works as follows.

When transporting the material through the conveyor system 1, 2, 3, the current value of the performance of the initial conveyor 1 is measured by sensor 4 and is presented in the form of a frequency-modulated pulse signal, each pulse of which in a certain equipment reflects the amount of material passed through the section of the conveyor corresponding to the installation site sensor 4 performance. This sequence of pulses goes to the main input 8 of the register, consisting of sections 9, 10, 11. The values of the speeds of movement of the belts of each of the conveyors 1, 2, 3 and using the corresponding speed control nodes 5, 6, 7 are also converted into proportional frequency signals and arrive at the shift inputs 12, 13, 14 sections 9, 10, 11 of the register.

In this case, the pulses input to the main input 8 of the register advance along the cells of its sections 9, 10, 11 (the position of the excited cells of the register moves). At the same time

the light of the vehicle is connected to the cells of section 9, 10, and the corresponding cells of sections 16, 17, 18 of the mnemonic scheme.

Consequently, the rate of advancement of pulses along the cells of sections 9, 10, of the sequential register and the image of the luminous cells of sections 16, l7, 18 of the mimic, linear density and distribution of And | Mpulso1V along the register of the indicated ovary cells of the mnemonic scheme reflect the degree of congestion of the corresponding section conveyors and the distribution of moving material along the length of the conveyors.

In this way, a moving image of the material flow, reflecting the speed of movement, the amount and distribution of material along the conveyors, is obtained, since the mnemonic scheme of the device quantitatively and qualitatively reflects the working process of the technologically interconnected conveyors in a consistent form.
