Introduction of mine winch

Introduction

       Mine winch Is used in mines, with the help of wire rope traction to achieve its purpose of work. It includes "friction haulage winch", "dispatching winch", "prop pulling winch", "scraper winch" and "safety winch"

Applied discipline
Coal science and Technology (discipline); mining machinery engineering (secondary discipline); mining vehicle is a common winch, also known as winch, mainly used in construction, water conservancy engineering, forestry, mining, wharf

Mine winch is the main equipment which is convenient for people and materials in mine work. The use of mine winch not only ensures the personnel and working process, but also improves the efficiency of mine operation.

The development process of the electronic control system of mine winch should be towards the new equipment of unmanned, network, remote control and full automation.

The characteristics of mine frequency conversion electric control are as follows:

1. The console uses FX2N PLC as the main control equipment. It is designed and manufactured in accordance with the EMC standard of GB / T17626.

2. Because the control system is controlled by PLC, the locking control of main belt conveyor and front and rear equipment can be easily realized.

3. The master control station detects the conveyor speed in real time, controls the zero speed braking and automatic braking of the conveyor to avoid the conveyor rolling, inverter and motor over-current.

4. The frequency converter is used to complete the motor start-up and speed regulation requirements of the belt conveyor, and the belt conveyor is in a long-term low-speed operation state (such as transport vehicle, rope detection, belt inspection), which has obvious energy-saving effect.

5. Through the network platform, the frequency converter can realize the automatic data exchange, has the function of automatic adjustment of operating parameters, and has good dynamic follow-up of master and slave motors to ensure the power balance of multiple motors.

6. The system has fault monitoring and reliable fault protection. With over-voltage, over-current, under voltage, short-circuit, grounding, overheating and other protection functions.

7. It has the function of low speed tape detection. The tape speed can be adjusted from 0.2 M / s to VE.

As the frequency conversion mine hoist for ore construction operation, it is necessary to ensure the perfection of its electric control equipment, realize the numerical control and intelligent control of the mine, and output high production resources while ensuring the operation, so as to lay a good foundation for the new digital mine in the future.

The mine 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. Of course, only when the following conditions are met can we use the dispatching winch.

1. Ambient temperature: - 10 ~ 40 ° C

2. The relative humidity of the environment shall not exceed 95 (25 ° C)

3. The altitude is lower than 2000m

4. The content of methane, coal dust, hydrogen sulfide and carbon dioxide in the surrounding air shall not exceed the content specified in "coal mine regulations".

What is the category of mine winch?

The winch is divided into manual, electric and hydraulic according to power. It can be divided into construction winch and marine winch.

Winch can be divided into: Marine winch, engineering winch, mine winch, cable winch and so on.

According to the drum form, it is divided into single drum and double drum.

According to the drum distribution form, it can be divided into parallel double drum and front and rear double drum.

Special types of winches include: frequency conversion winch, double drum winch, hand brake lever type double brake winch, winch with limiter, electric control winch, electric control clutch winch, large double cylinder double brake winch, large external gear winch, large hydraulic winch, large external gear pulley rope arranging winch, double traction wheel winch, large hydraulic double cylinder double brake winch, frequency conversion belt limiter Rope groove winch.
