What are the precautions for safety inspection of coal mine belt conveyor?

First of all, it depends on whether this mining machine chooses the V-belt of Puguan or the belt of the Puguan crusher, because the V-belt of Puguan or the special belt of the Puguan crusher belongs to the top V-belt products in the world, which does not run long, is maintenance-free, and does not need to be adjusted again once hung up.

Replace it regularly.

Preparation before installation.

1: Technical preparation.

A: The center line of the belt of the roadway and the center line of the roller of the belt head of the belt are required to be released by the geological survey department, and the base height of the belt is determined. The centerline of the belt requires a point every 50 meters.

B: Prepare the technical information for belt installation.

2: Equipment preparation: The parts of the belt to be installed must be overhauled and the number is sufficient.

3: Preparation of tools: construction tools must be ready.

4: Personnel preparation: The construction personnel must have a special person in charge, and all construction personnel must be familiar with the performance and working principle of the equipment.

Second, the installation method:

1. Installation sequence: belt head and transmission part, belt storage compartment, belt middle frame, belt tail section wear belt.

2. First of all, the belt double layer is spread along the machine lane, and then laid in accordance with the installation order, after the belt frame is installed, the belt joint is done and connected with a through strip and the middle belt is put on the shelf, and the head and tail roller belts are worn at the same time. When the main and auxiliary rollers wear the belt, the motor should first be connected to the power supply, and then the belt of the storage bin section should be worn through the inching motor and with the cooperation of manpower.

3. The belt installation center line must be guaranteed to coincide with the belt center line of the measuring and placing to ensure the installation quality. When making belt joints, each belt buckle must meet the requirements of the standard.

3. Safety technical measures.

1. Transportation method.

The use of 5T electric locomotive and JD winch with transportation, 5T and above large pieces are only allowed to hang one car at a time, and the rest of the small pieces can be transported in tandem, but the amount of tandem is not more than 2 cars each time, and it must be connected with a short rope buckle.

2. The following regulations must be complied with when lifting the equipment during belt installation:

a. Lifting tools must be in good condition.

B. Before lifting, it is necessary to carry out a test lifting to ensure that there is no problem before lifting.

c. It is strictly forbidden for anyone to work, walk or stay under the lifting equipment.

d. The lifting tool must be inspected by a special person.

3. When wearing the belt, it should be noted that no one should work within the scope of the drum when the belt is jogged to prevent accidents.

4. After the belt is installed, there is no problem after inspection, and the test run is carried out under the condition that the belt protection and signal are complete and complete.

5. The belt must be operated by a skilled belt driver during the test run, and there are no less than three people in each head and tail, and one person is required to be supervised every 100 meters in the middle section. The trial operation personnel must be neatly dressed and the cuffs must be buttoned up. Problems found during trial operation should be stopped in time.

"Coal Mine Safety Regulations" - Coal Industry Press, page 323, Section 3, belt conveyor transportation, Article 625, the use of belt conveyor transportation shall comply with the following provisions:

1. The maximum inclination angle of materials transported by belt conveyor shall not be greater than 16 degrees upward, 14 degrees in severe cold areas, and 12 degrees in downward direction, except for special belt conveyors.

2. The static safety factor of the wire rope core conveyor belt is favorable, generally unfavorable 3. The transportation capacity of the belt conveyor should match the capacity of the front equipment.

Hope it works for you.

When using roller-driven belt conveyor for transportation, the following provisions should be observed:

a) Flame retardant conveyor belts must be used. The flame retardancy and antistatic properties of the non-metallic material parts of the belt conveyor idler and the rubber material of the rubber lagging roller must comply with the relevant regulations.

2) There should be sufficient lighting in the roadway.

3) The drive drum must be equipped with anti-skid protection, coal stacking protection and anti-deviation device.

4) Temperature protection, smoke protection and automatic sprinkler devices should be installed.

5) The belt conveyor installed in the main transportation roadway must also be installed:

1. Conveyor belt tension reduction protection device and anti-tear protection device;

2. Protective fences at the nose and tail to prevent personnel from coming into contact with the drive drum and guide drum.

6) The belt conveyor used in the inclined shaft roadway must be equipped with an anti-reversal device and a braking device at the same time when it is transported; When disembarking, a braking device must be installed.

7) It is strictly forbidden to use flammable transmission medium in the fluid coupling (the speed-regulating fluid coupling is not subject to this limitation).

8) A bridge should be set up at the pedestrian crossing the belt conveyor in the belt conveyor roadway.

9) The belt conveyor should be equipped with a soft start device, and the lower belt conveyor should be equipped with a soft braking device.
