IntroductionThe main role in the development of Ukrainian industry has the fuel and
energy complex. The functioning and development of fuel-energy
complex of Ukraine is largely predetermined by the state and
development of coal industry, which is widespread in our region.

- Finding the dependencies between the amplitude-frequency characteristics of spatial longitudinal-transverse vibrations oblique head of the rope and the string geometry, regime and the inertial parameters of the lift installation.
- Development of a device for absorbing vibrations of the rope mine hoisting plant.
- Development of device management for swallowing vibration of the rope and automation system drive shaft hoisting plant using this device.
- Justification for the use of sensors and a complete electric drive with a device for swallowing vibration rope mine hoisting plant.
Relevance and motivation of the subjects
Most
of the lift installation - lift - a complex electromechanical
mechanism,
consisting of individual elements that perform different functions.
Rational
choice of these elements and the establishment of optimal modes of
operation of
the machine completely determine the safety and efficiency of operation
of the
lift installation. In this regard, a comprehensive review of existing
theory
and practice of calculation and choice of individual elements of the
lift
deserve special attention when designing new or upgrading existing mine
hoisting plant. To determine the effectiveness of the installation, you
must
set the optimum weight lifted load, skips, to determine the optimal
values of
acceleration, deceleration and speed recovery, select and calculate the
capacity of the drive motor, the location of the lift on a shaft,
determine the
reduced mass of the lift installation, efficient power lifting, power-
energy
efficiency and lift installation, construction starting characteristics
of
motors and to calculate the rotor resistance.
Review of
research and development on this topic
Research
in this area were OA Goroshko, GN Savin, FV Florinsky, LV Kolosov, VI
Dvornikova,
AN Obukhov, GA Trifanova etc.
It
is based on a mathematical model of nonlinear vibrations of a string
and
plumb-line rope mobile hoisting plant Ilyina S.R. (Candidate of
Technical. Sciences,
Senior Scientist), Samusia S.V. (Postgraduate, Institute of Geotechnical
Mechanics,
NS Polyakov NAS). This model is applicable to stationary lift
installations, as
based on the provisions designed for them. The model took into account
the
joint interaction of the transverse vibrations of a string of rope and
longitudinal vibrations of the branches of the rope.
Own results
To
redeem string vibration of the rope propose to use the device, exciting
rope
during emergency braking. The device consists of: 1 - frame 2 -
frame-catcher,
3 - arch strap 4 - hydraulic jacks; 5 - compressing the spring 6 -
guide frame.
The
frame is designed for mounting on it the elements of the device and
should
provide structural rigidity.
Frame-catcher and arched strap designed to
secure the
rope in the bottom of the frame during emergency braking. The surfaces
of
frame-catcher and curved plates coated with polyurethane to prevent
damage to
the rope in contact with them. Hydraulic press the arched bar from the
frame-catcher in the normal mode of operation the lift installation.
When
emergency braking valve opens allowing fluid fast enough to leave the
piston
cavity hydraulic jacks. Compressing the springs are needed for pressing
curved
strips to the frame-catcher in case of emergency braking. Guide the
beam to
move on it frame-catcher.
The
device is a drum with a movable frame which moves along the guide and
has an
electric drive. Status frame is determined by the signal
coming from
komandoapparata management and depends on the position of the vessel.
To
prevent unstable oscillations, the ratio of the lengths of strings and
a
plumb-line of the rope should not be equal to 1 and 5. To do this,
you must install two devices on copra, which will regulate the length
of the
string depending on the position of lifting the vessel during emergency
braking. Strobes only one of the devices on copra and the device in the
drum. Upon
activation of the device for calculating the vibrations through a
system of
differential equations, will not be considered complete length of the
string
from the drum to the copra lstr, but only a segment of copra to one of
the
devices. Ie length of the string in this case will be equal to L1 or L1
+ L2,
depending on the position of lifting the vessel.
With
the passage of a vessel with electromagnetic sensors installed in the
trunk, a
signal to the control panel of the lift, and then determined which of
the two
devices is active.
