2 m hoist in Luoshan coal mine

1. Luoyang mining Machinery Factory (Luoyang mine) is a large enterprise procing large heavy machinery and equipment, belonging to CITIC Group. Because it is a large heavy equipment, it is usually proced in a single piece or small batch, often a part has dozens of tons, mainly steel and iron, casting, forging, machining, heat treatment capacity and various detection means are very strong.

2. Mine hoist this proct is mainly used in coal mine, metal mine and non-metal mine to lift materials, ore, lift personnel and lower material equipment, also can be used for other traction transportation.

3. (1) Before adjusting the rope, the two hook lifting containers must be emptied, and the container on the side of the movable drum must be put to the bottom of the well
(2) when adjusting the rope. The movable drum must be fixed first, and the clutch can be opened by force
(3) when aligning the rope each time, align the rope after the oil is injected into the movable drum sleeve
(4) gear alignment should be carried out before the clutch is engaged. After adding oil on the teeth, set up the clutch again
(5) when the clutch engagement is too tight, the clutch can be pulled out or can not be closed, the power can be sent to make the dead drum rotate a little and then close again, so that the operation can be hard hit to prevent damage to the clutch
(6) it is strictly forbidden to lift or lower with a single hook ring Rope adjustment
(7) after adjusting the rope, check the Yele system, and the position of each solenoid valve and clutch oil cylinder is accurate. Only when it is confirmed that there is no error can it be lifted normally
the right hub of the fixed roller is fixed on the main shaft with tangential key, and the left hub is sliding on the main shaft. The right wheel hub of the traveling drum is sliding mounted on the spindle T through the bushing, and there is a special lubricating oil cup to ensure lubrication. The bushing is used to protect the spindle and hub from abrasion and abrasion when adjusting the rope. The left wheel hub is fixed on the shaft with tangential key and connected with the drum through the rope adjusting clutch. The drum is of welded structure, and the spoke is made of steel plate. Generally, the outer side of the cylinder shell is equipped with a wooden lining, and there is a spiral rope groove on the wooden lining, so that the wire ropes can be arranged regularly and the wear of the wire ropes can be reced. The double drum hoist is equipped with a rope adjusting clutch, which is used to connect or disconnect the traveling drum from the main shaft, so that when the rope length needs to be adjusted or the lifting level needs to be changed, the two drums can move relatively. There are three main types of rope adjusting clutch: gear clutch, friction clutch and worm gear clutch. Gear clutch is widely used.

JK - represents mine hoist

Z - represents DC speed regulation

3.2 - winch diameter 3.2m

18 - maximum lifting capacity 18 tons

According to GBT 25706 coal mine machinery proct model compilation method,

< UL >

mine hoist

is also called rolling mine (JK), the diameter of winch drum is more than 2m (including 2m)

mine hoist

is also called rolling lift (JT), the diameter of winch drum is less than 2m (excluding 2m)

< / UL >

both are a type of machinery, The difference is that the lifting force or traction of mine hoist is larger than mine hoist, and the price will be higher

6. A 10 kW hoist will do.

8.

Hello! JK type mine hoist is a winch with more than 2m drum. 1.2m is JTP model and disc brake. It is not an obsolete equipment. Please rest assured to use it

Hebi winch sales center answers for you

10. Hello
your answers are as follows:
1. Your average slope is 24 degrees, so the angle is relatively large
2. Although you don't provide the hydraulic model and the number of disc brake models, I will consider your downward braking deceleration and upward braking deceleration based on my previous experience
3. You can use 3T at most. No more

although your question has been modified and supplemented, I don't mean that. You must provide detailed technical parameters and technical background before calculation, such as (whether people lift together, effective area of disc brake, etc.)
it has a lot to do with the safety factor. This calculation must be combined with the "mine fixed equipment manual" and "coal mine safety regulations" (2009) in the relevant provisions of the calculation, must not be arbitrary.
