Customized Professional Hydraulic Explosion-Proof Hoist Supports Height/Load Adjustment

 Customized Professional Hydraulic Explosion-Proof Hoist Supports Height/Load Adjustment

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;

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

Product technical features:
1. Good explosion-proof performance;
2. Stable stepless speed regulation performance and low-speed operation performance;
3. Obvious energy-saving effect: Due to the use of hydraulic closed-loop transmission, the system is always in a power generation braking state under the lowering condition, so that the gravitational potential energy is converted into electrical energy to feed back to the power grid, which not only reduces the heating of the hydraulic system, but also saves electrical energy, and the energy-saving effect is obvious. Compared with the low-speed hydraulic motor hydraulic winch, the hydraulic winch driven by the high-speed hydraulic motor has high transmission efficiency and good energy-saving effect.
4. Flexible technical parameters, reasonable matching, and large selection space: The speed ratio parameters of the reducer can be reasonably selected according to the load and speed, so that the parameters of the hydraulic pump and hydraulic motor can be optimally matched. The variable pump-variable motor speed regulation method is adopted (the low-speed hydraulic motor cannot), which can realize light-load high-speed and heavy-load low-speed operation conditions, and give full play to the equipment capacity. Compared with the low-speed hydraulic motor solution, the pulling force or speed can be increased under the same power; and under the same maximum pulling force and maximum speed, the installed power can be reduced, which can save electrical energy.
