Use of rake mine winch
Rake mine winches are mainly used in pits and open-air areas of metal mines and other mines for mineral harrowing and filling work on working surfaces that are not horizontal or inclined.
Working principle of rake mine winch
The rake mine winch is driven by a steel wire rope wound on a drum to make a reciprocating movement to haul materials.

Introduction of JD series dispatch winch
JD series dispatch winch is explosion-proof type, and it is used for underground mine or ground loading dispatch grouping ore carts, consignment ore carts in the middle lane and other auxiliary transportation. The winch adopts planetary gear transmission. The winch has the characteristics of compact structure, good rigidity, high efficiency, convenient installation and movement, stable starting, flexible operation, reliable braking and low noise. It can be applied to the occasion with more biogas or coal dust. Because the winch drum is equipped with protective devices, the whole machine is very safe and reliable to use and operate.
Classification of JD series dispatch winch
JD dispatching winch is mainly used to mine ore carts and other auxiliary transportation work in coal mines and other mines in roadways with an inclination angle of less than 25 degrees. It can also be used to dispatch marshalling carts at loading stations on mining faces and heading faces.
Main classification: JD-0.5 (3KW), JD-1 (11.4KW), JD-1.6 (25KW), JD-2 (25KW), JD-2.5 (40KW), JD-3 (45KW), JD-4 ( 55KW)

Introduction of Two Speed Pillar Winch
The two-speed column return winch has two speeds, fast and slow. It is mainly used for auxiliary transportation work such as underground coal mining working face, comprehensive mining equipment and various mechanical and electrical equipment relocation, as well as underground mining working face, bottom yard, uphill and downhill The dispatching of coal carts, material transportation at coal mine grounds, etc., can also be used for returning to the roof of the mining face. The winch of this system adopts the form of bevel gear transmission, with simple structure, safety and reliability, and convenient maintenance. The small width and height of the winch is suitable for working in a narrow space. The winch is easy to operate and can be used in conjunction with the speed control handle switch.
Introduction of back column winch
Column winch, also known as slow speed winch, is used to return the column to the roof of the coal mining face. Because of its low height and light weight, it is especially suitable for thin coal seams and steeply inclined coal seam coal mining faces, as well as various metal mining faces for recovering metal pillars sunk into the floor or buried by vermiculite. With the increase of the degree of mechanized coal mining, it is more and more widely used in mechanized coal mining working faces, as the installation, recovery and traction of various equipment and spare parts. The main models are: JH-5, JH-8, JH-14, etc.
Features of JH-8 back column winch
JH-8 back column winch adopts spherical worm gear pair transmission, compact structure, small size, can go down the whole machine, symmetrical structure, long shape, base shape is sled, self-moving under the well is smooth and convenient; low center of gravity, rigid base Well, it can be used for topping pillars and ground anchors. It is easy to install, runs smoothly, and is safe and reliable.

|JH-8||80kn||15.5mm||80m||7.5kw||1593 * 530 * 670mm||600kg|
|JH-5||50kn||16m||80m||7.5kw||1450 * 510 * 515mm||610kg|
JTP series mining hoist winch application
This series of hoisting winches are mainly used in shafts and inclined shafts to lift coal, ore, vermiculite, and lift personnel, materials, tools and equipment.
JTP series mining hoisting winch structure
The whole structure of JTP mining winch adopts: the drum, reducer and motor are arranged in a line. The main components are composed of: a main shaft device, a reducer, a hydraulic disc brake, a hydraulic station, a depth indicating device, a speed measuring power generating device, a mechanical centrifugal speed limiting device, a console and an electronic control device.
Analysis of JTP series mining hoist winch
There are two types of JTP mining winches: AC drag and DC drag; the speed adjustment methods under AC drag are also divided into: AC winding motor rotor series resistance speed control and variable frequency speed control. Electrical equipment control methods include: relay control and PLC control, voltage range: 380V-10KV. In the PLC control mode, the fault diagnosis display, color screen touch screen and reserved network interface can be configured according to user requirements, and the remote network control of the device can be realized.
Application of JZ series drilling winch
JZ series drilling winches are mainly used for the suspension equipment, water pumps, water pipes, grouting pipes, wind pipes and other heading equipment and tensioning and stable ropes in shaft boring of coal mines, metal mines and non-metal mines. The winch is mainly used to replace the tail rope connected between the two cages of the hoist; and it is best to replace the flat rope, and it can also be used as a shaft winch with the same performance as the shaft.
The composition of JZ series drilling winch
This series of winches is a winding type, which is mainly composed of main shaft device, reducer, elastic coupling with brake wheel, working brake, safety brake, machine base, motor and other components.
Adjustment of JZ series drilling winch
After the winch is installed, it must be inspected and adjusted.
1. Open gear transmission, the tooth side clearance is 0.42 mm, the contact area along the tooth height is not less than 40%, and the extension tooth length is not less than 50%.
2. Check whether the transmission system of the working brake is flexible and reliable, and adjust the gap between the brake shoe and the brake wheel when the brake is released, not more than 0.7-0.8mm. And when the brake is released, the gap between the brake shoe and the brake wheel is not more than 1.5mm.
3. Check whether the control appliances of the work brake and safety brake are interlocked with the main motor, that is, start the work brake of the main motor to release the brake, stop the work brake of the main motor, and start the main motor only when the safety brake is released.
