Safety technology for installing the scraper

1. The installation of the scraper should be directed by the team leader to coordinate with the on-site command. The full-time machine electrician holds the certificate and works according to the chapter.

2. The scraper should be disassembled into small pieces for transportation as much as possible. The loading must be stable. Before the shipment, the system should check the shipping route and the winch. The clearance of the roadway is not enough, the track does not meet the requirements, and the maximum tension of the winch wire rope and The safety factor is not enough to be shipped.

3. When the assembly surface of the scraper is disassembled and transported, protective measures should be taken to prevent damage.

4. The scraper is transported to the Shangshun trough yard. After the manual cart is lifted to the upper gate, it needs to be manually transported to the 11 mining belt for installation.

5. When driving the cart, it should be executed as follows:

1), only one car can be pushed once. Do not push the cart on both sides of the mine car. The distance between the same carts shall not be less than 10m when the slope of the track is less than or equal to 5‰; when the slope is greater than 5‰, it shall not be less than 30m; when the slope is greater than 7‰, the manual cart is strictly prohibited.

2) When you are pushing the cart, you must always pay attention to the front. When you start the cart, stop, get out of the way, find someone or obstacles in front of you, go down the cart from a steep slope, and get close to the turnout, corner, roadway, 硐When the room is exported, the cart person must issue a warning sign in time.

3) It is strictly forbidden to fly the car.

6. When manually lifting heavy parts, the following rules should be observed:

1) When lifting heavy objects by hand, it should generally be carried out by a group of 5 people, 4 people carrying the transportation, and 1 person for safety monitoring;

2) Before lifting the heavy object, use the hemp rope or the wire rope to bundle the heavy objects firmly;

3) Before lifting the shipment, the personnel should first coordinate the slogan and lift it at the same time;

4) Before lifting the transportation, the roadway clearance, roof and other conditions should be thoroughly checked to ensure smooth passage; if there are obstacles, it must be removed before lifting.

7. Before installation, check the installation location and the support condition of 5m before and after the installation. If the support is not perfect, take measures to strengthen it first.

8. Lifting scraper motor and tooth box use 2T chain hoists. The chain hoist must be rooted on the anchor cable. The connection with the heavy object should ensure the stability during lifting. There should be a special person to observe the lifting point and the lifting part. It is strictly forbidden to stand in the range of its swing, and it is not allowed to stand on the hoisting object.

9. The equipment installation should be stable and reliable. After the installation is completed, the test can be started, and the problem can be found in time to find the cause adjustment until it is in good condition.

10. The scraper driver must undergo formal professional training and hold a certificate. The driver who is familiar with the structure, performance and principle of the scraper conveyor drives the car.

11. When installing the scraper, the switch signal bell should be installed at the same time and ensure that it is in good condition.

12. Before driving, we must carefully check whether the mechanical operation of the whole system is normal, whether the lubrication is good, whether the switch signal bell is faulty, and insist on driving system after the test drive.

13. Before installation, the machinist should check the hydraulic coupler, chain, scraper, strong tooth cover and other parts of the scraper. When the problem is found, the problem is immediately stopped and the operation is prohibited.
