Multi-rope Friction Mine Hoist -JKM Tower Multi-Rope Friction Mine
Hoist,JKMD Landing Multi-Rope Friction Mine Hoist
1. The technical characteristics of mine hoist designed and
developed by Luoyang Mining Machinery Factory and Research
Institute are:
(1) The use of integral, two-flap type, four-flap type of various
types of drum;
(2) Drum rope groove adopts processing spiral rope groove, folding
rope groove or wood lining and plastic lining pressed spiral rope
groove, steel rope transition device is set between the ropes;
(3) Using cylinder rear disc brake, electro-hydraulic joint
control; Hydraulic station can be divided into two types: middle
and low pressure and middle and high pressure. There are two kinds
of constant braking force electric delay and hydraulic delay
two-stage brake in middle and low pressure hydraulic station;
Middle and high pressure hydraulic station has two forms of
constant deceleration and constant braking torque secondary
braking. Hydraulic station can be equipped with pressure sensor,
pressure relay;
(4) Spindle and drum are connected by plane friction with large
torque;
(5) Signal monitoring device composed of photoelectric encoder,
self-leveling machine and low-speed Chilean tachogenerator, with
overspeed, overwinding, depth indication failure, brake shoe wear,
spring fatigue and other perfect monitoring and protection
functions;
Bring console has integral and two forms of separate all adopt the
electric meter of integrated light, reliable in performance and new
type integral operation handle, and a digital depth indicator and
digital and screw type depth indicates the depth indicator system
as a whole, has a mesa of industrial TV or computer, printer and
other special;
(6) The pulley device adopts integral or two-flap welding
structure, supported by rolling bearing and friction liner with
POLYvinyl chloride or nylon on the rim;
(7) Can be equipped with mine hoist network control and diagnosis
system.
Advantages of Conveying Hoisting Machine
2. Advantages of multi-rope friction type mine hoist:
(1) The load is borne by a number of wire rope, wire rope diameter
is small, equipment size is small. That is, under the same diameter
specification, the lifting capacity is large;
(2) The wire rope is put on the drum, not affected by the rope
capacity, suitable for deep Wells;
(3) small inertia, small energy consumption under the same output;
(4) when the tank is stuck or overrolled, it can slip to avoid
breaking the wire rope;
(5) the possibility of wire rope breaking at the same time is
small, without anti-drop device;
(6) The same number of left twist and right twist wire rope can be
used to offset the loose twist trend, to avoid the pressure of the
container ear on the tank channel;
