Hydraulic Explosion-Proof Hoist Conveying Hoisting Machine Reel Diameter 2500 Mm

1. Basic introduction of hydraulic explosion-proof hoisting winch

(1) Product type JT(K)YB-*×*J series hydraulic explosion-proof hoists and hoisting winches use explosion-proof squirrel-cage asynchronous motors to drive bidirectional variable hydraulic pumps, and drive multiple high-speed hydraulic motors to rotate through closed circuits. The reel is driven to rotate by the reducer.

(2) Marking example:

a) Reel diameter 2500 mm, reel width 2000 mm, reducer drive, electro-hydraulic proportional, PLC control, digital depth indicator display single drum hydraulic explosion-proof hoist is marked as: JKYB- 2.5×2.0J (BP) Hydraulic explosion-proof hoist;

b) Reel diameter 1600 mm, reel width 1200 mm, reducer drive, hydraulic control, mechanical depth indicator display. The double-drum hydraulic explosion-proof hoisting winch is marked as: 2JTYB- 1.6×1.2J.

3. Application and product introduction of hydraulic explosion-proof hoisting winch

JT(K)YB-*×*XP series hydraulic explosion-proof hoist and hoisting winch are used for lifting and lowering personnel and materials in occasions containing explosive gas such as methane-air mixture and coal dust. , liquid integration of new products. At present, there are two standard series of single cylinder and double cylinder, and 18 standard specifications of products, and can also be extended to non-standard specifications according to user needs. The main transmission mode of the product adopts the explosion-proof motor to directly drive the high-pressure variable pump, drives multiple quantitative hydraulic motors and variable hydraulic motors through the hydraulic closed circuit, and then drives the spindle and the reel to rotate through the planetary gear reducer to complete various working conditions of the lifting process. 

4. Product technical features of hydraulic explosion-proof hoisting winch

(1) Good explosion-proof performance;

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

(3) The energy-saving effect is obvious: due to the use of hydraulic closed-loop transmission, the system is always in the state of generating and braking under the condition of lowering , the energy saving effect is obvious. Compared with the low-speed hydraulic motor hydraulic winch, the high-speed hydraulic motor-driven hydraulic winch has high transmission efficiency and good energy-saving effect;

(4) Flexible changes in technical parameters, reasonable matching, and large room for selection: the speed ratio parameters of the reducer can be reasonably selected according to different loads and speeds, so that the parameters of the hydraulic pump and hydraulic motor can be optimally matched, and the variable pump-variable motor is adopted. The speed regulation mode (low-speed hydraulic motor cannot) can realize the 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 scheme, the pulling force or speed can be increased under the same power; while the maximum pulling force and maximum speed are the same, the installed power can be reduced, which can save electricity;

(5) The compact structure and small volume can save energy Construction cost of the chamber: Due to the direct connection between the planetary gear reducer and the main shaft, and the direct connection between the high-speed hydraulic motor and the planetary gear reducer, the axial dimension of the main engine is short, and the hydraulic system is compactly arranged, so the structure is compact and the volume is small. Save the cost of chamber infrastructure;

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

(7) Sensitive, simple and convenient operation: Only one handle can be used to complete the whole operation process of the winch, and the operation is sensitive, accurate, simple and reliable;

(8) The slope heavy-load starting performance is stable, safe and reliable;

(9) High operating safety and reliability: Compared with the low-speed and high-torque hydraulic motor transmission scheme, the high-power hydraulic winch driven by the high-speed hydraulic motor has high safety and reliability, and there has never been a "sports car" accident;

(10) Complete safety protection measures, in line with the requirements of the "Coal Mine Safety Regulations" (2001 edition) and the requirements of coal safety signs: the product is equipped with over-rolling, over-speed, overload, under-voltage, deceleration, brake shoe clearance, zero-position interlock, depth Safety protection devices such as indicator failure, loose rope alarm, over temperature alarm, liquid level alarm and emergency braking. Comply with the requirements of "Coal Mine Safety Regulations" and the requirements of coal safety signs;

(11) It has good safety braking performance and good braking reliability: the hydraulic braking circuit controlled by the pressure valve has the function of separately setting the braking deceleration of lifting heavy load and lowering heavy load. It can not only ensure that the lifting heavy load does not loosen the rope, but also ensure that the lowering heavy load meets the deceleration requirements of the safety regulations, and has good secondary braking performance.
