Hydraulic Explosion-Proof Hois Conveying Hoisting Machine And Coal Mine Hoist

1.Application and product introduction

JT(K)YB-*×*J series hydraulic explosion-proof hoist and hoisting winch adopts flameproof squirrel cage asynchronous motor to drive two-way variable hydraulic pump, through the closed circuit to drive a number of high-speed hydraulic motors to rotate, through the reducer to drive the drum rotation.

JT(K)YB-*×*XP series hydraulic explosion-proof hoist and hoisting winch is used for containing methane air mixture and coal dust and other explosive gas occasions, used to lift and lower personnel, material lifting equipment, is a new product of machine, electricity, liquid integration.

2. Product technical features:

(1) Good explosion-proof performance;

(2) Stable stepless speed regulation and low speed operation performance;

(3) Obvious energy saving effect: Due to the adoption of hydraulic closed circuit transmission, the system is always in the power generation braking state under the lowering condition, so that the gravitational potential energy is converted into electric energy to feed back to the power grid, which not only reduces the hydraulic system heating, but also saves electric energy, and has obvious energy saving effect. Compared with the low speed hydraulic motor hydraulic winch, the hydraulic winch driven by high speed hydraulic motor has high transmission efficiency and good energy saving effect.

(4) The technical parameters of flexible, reasonable matching and selection scope changed: according to the load and speed reducer ratio parameter selecting different size, make the hydraulic pump, hydraulic motor parameters to achieve the best match, the variable pump, variable motor speed control method (low speed hydraulic motor is not), which can realize high-speed light load and overload low-speed operation condition, give full play to the equipment capacity. Compared with the low speed hydraulic motor scheme, the tension or speed can be increased at the same power. When the maximum tension and maximum speed are the same, the installed power can be reduced and electric energy can be saved.

(5) Compact structure, small volume, can save the cost of chamber construction: because of the use of planetary gear reducer and spindle direct connection, high-speed hydraulic motor and planetary gear reducer direct connection, the axial size of the host is short, the hydraulic system arrangement is compact, small volume, can save the cost of chamber construction.

(6) The equipment has long service life, easy to purchase standard spare parts and low price, small maintenance workload and low comprehensive operation cost. Compared with the low speed hydraulic motor scheme, the high speed hydraulic motor is the standard hydraulic component, stable performance, long life, easy procurement, cheap price, reduce the maintenance workload. Although the one-time investment is high, but the comprehensive operation cost is low.

(7) The operation is sensitive, simple and convenient: only one handle can complete the whole operation process of the winch, the operation is sensitive, accurate, simple and reliable.

(8) Slope heavy load starting performance is stable, safe and reliable.

(9) High safety and reliability in operation: compared with the low-speed and high-torque hydraulic motor transmission scheme, the high-power hydraulic winch driven by high-speed hydraulic motor has high safety and reliability, and has never had a "sports car" accident.

(10) is complete, the safety protection measures in line with the "coal mine safety regulations" (2001 edition) and coal Ann logo requirements: product set a volume, speed, overload, under voltage, deceleration, brake shoe clearance, zero failure, loose rope chain, depth indicator alarm and over-temperature alarm, liquid level alarm and emergency braking safety protection device. Meet the requirements of coal mine safety Regulations and coal safety marks.

(11) It has good safety braking performance and good braking reliability: the hydraulic braking circuit controlled by pressure valve has the function of lifting heavy load and lowering heavy load braking deceleration respectively. It can not only ensure that the rope is not loose when lifting heavy load, but also ensure that the heavy load can meet the requirements of deceleration in safety regulations, and has a good secondary braking performance.

3. Suitable working conditions and working environment:

The main machine should be used in the ambient temperature of 5℃ ~ 40℃, the electronic control system should be used in the altitude of not more than 1500 meters (above 1500 meters can be specially ordered), the surrounding air relative humidity is not more than 95% (25℃), must be able to prevent water and liquid intrusion into the electrical equipment, no violent vibration, no corrosive gas environment. In addition, it should also meet other conditions specified in the instructions of the manufacturer of a single equipment.
