What are the technical measures for dismantling the scraper conveyor

The technical measures for dismantling the scraper conveyor include the following aspects:

1. Preparation work: Adequate preparation work must be carried out before demolition. Firstly, the equipment needs to be shut down for inspection and necessary maintenance and repair. Secondly, a safety check should be conducted around the site to confirm that there are no debris or dangerous objects, such as slippery animals, electrical wires, etc. Relevant warning signs should also be set up to remind staff to pay attention to safety.

2. Job Safety Plan: Before carrying out any operation, a job safety plan must be prepared and the consent of equipment related personnel must be obtained. The plan should include homework steps, safety measures, emergency response measures, and other contents. During the homework process, it is necessary to operate according to the plan and make timely adjustments as needed.

3. Safety protection awareness of operators: Operators must strictly follow the operating specifications and safety operating procedures when carrying out demolition operations. At the same time, it is necessary to strengthen the awareness of safety protection, carefully read the equipment operation manual, and closely monitor the operation status of the equipment to confirm that it is in a safe state during operation.

4. Protective measures: Due to the easy blockage of materials during dismantling, a series of protective measures need to be taken. Specific measures include: before dismantling, the materials in the tank must be emptied to avoid accumulation and jamming. Use the excavation tools made for dismantling operations, and do not use ordinary tools. Seal the removed groove or set up a safety fence to prevent workers from falling into the groove. During the operation, keep it clean to avoid further blockage.

5. Choose suitable excavation tools: Due to the easy blockage of materials in the middle groove, using traditional excavation tools will increase the difficulty of operation and may lead to jamming and tool damage. Therefore, excavation tools specifically designed for scraper conveyors should be selected to ensure smooth and secure operation.

6. Adopting Anran monitoring system: Anran monitoring system is an important means of Anran control for scraper conveyor, which can achieve real-time monitoring, warning and control of equipment operation. When dismantling the central groove, a corresponding safety monitoring system can be used to monitor and control the operation status of the equipment, in order to avoid safety issues such as material blockage or equipment damage in the groove.

7. Adopt excellent cleaning methods: To avoid further blockage, excellent cleaning methods can be used. For example, using a high-pressure water gun for cleaning can remove dirt and debris, improve the cleanliness and quality of the equipment.

8. Pre construction cleaning work: Before construction, the scraper must be cleaned thoroughly and the coal blocking plate must be removed.

9. Electrical safety measures: Before cutting the chain, a dedicated electrician must first check the sensitivity of the switch before proceeding. When dismantling the scraper conveyor, the scraper chain should be cut off at the transition groove of the machine head first, and then the start switch of the scraper conveyor should be powered off and locked before proceeding with subsequent dismantling work.

10. Safety requirements for button operators: Button operators are strictly prohibited from standing on the machine head, motor, or gearbox to operate. They must operate from the side of the machine head and always pay attention to the operation process of the chain cutter when cutting the chain. If an accident occurs, stop the machine immediately and confirm the safety of the chain cutter.

11. Safety measures after dismantling the chain: After the chain is dismantled, the power should be cut off and locked, and a power-off sign should be hung. The chute can only be dismantled after the power line is removed. The power supply must be handled by a dedicated electrician, and the power outage and transmission system must be strictly implemented.

12. Safety requirements for dismantling and transportation of chutes: When dismantling chutes, one piece must be dismantled and transported one piece at a time, and four people must cooperate to lift and load them into mining cars. It is strictly prohibited to use chain plate machines to transport chutes, and personnel are strictly prohibited from standing under the chute to prevent it from sliding down and injuring people. It is strictly prohibited to work standing inside the chute and to step on the running scraper.

13. Safety requirements for manual loading of tanks: When manually loading tanks, they must cooperate with each other, coordinate and unify, and handle them gently to prevent injury to personnel.

14. Safety inspection before transporting scraper conveyor components: Before transporting scraper conveyor components, construction personnel must first check the transportation route to confirm that the route is unobstructed.

15. Inspection of roadway support: After personnel arrive at the site, they must first inspect the surrounding roadway support. If any unsafe conditions are found, they must be rectified immediately before operation can begin.

16. Requirements for stacking scraper conveyor components: Scraper conveyor components should be stacked neatly when transported to the installation site, and must be placed neatly according to requirements, without affecting pedestrians and subsequent work.

17. Safety requirements for using hammers or axes: When construction personnel use hammers or axes, no one is allowed to stand on the opposite side, and attention should be paid to the safety of surrounding personnel. It is forbidden to wear gloves when using hammers or axes to prevent injury caused by sliding hammers.

18. Safety requirements for using hand pulled hoists to lift equipment: When using hand pulled hoists to lift equipment, it is necessary to first check whether the performance of the lifting equipment is qualified. Only after passing the inspection can it be put into use. When using a chain hoist to lift equipment, it must be greater than the weight of the heavy object being hung. During the lifting process, all construction personnel must not approach the lifting equipment with any part of their body.

19. Safety requirements for joint handling of heavy objects: When two or more people jointly handle heavy objects, the construction personnel must have consistent slogans and lift or lower them at the same time to ensure consistent steps. At the corner, the person in front should send out a signal to remind the person behind to pay attention to safety.

Requirements for wearing labor protection equipment: All construction personnel must wear labor protection equipment properly.
