Mine operations are different from outdoor open-air operations. Due to the special nature of the environment, the use of anti-dropping devices is also strict. Before the operation, safety tests and inspections must be carried out on the anti-dropping devices, and the operations must be performed in accordance with the instructions to ensure safe completion Homework tasks.
1. Prepare the materials, spare parts, spare parts, tools, etc. used before the anti-dropping device test, and carefully check and test all kinds of safety protection equipment to ensure the smooth progress of all work and personal safety in the maintenance work.
2. All test personnel participating in the fall arrester must obey the command of the person in charge of safety in their work, and no one can act at will.
3. The staff must wear a qualified safety harness belt. The other end of the safety harness belt should be hung in a reliable position. The tools used during work must be fastened with the tool rope. The other end of the rope is fixed in a reliable position to prevent falling and hurting people. Or fall into the wellbore.
4. When working on the derrick, the person in charge of safety shall appoint a special person to guard and set up guards at the upper and lower wellheads. No one shall be close to the wellhead within 10m, and parallel operation of the upper and lower wellheads is strictly prohibited.
When the operator wears the high-altitude fall arrester, he opens the cutout of the fall arrester, wraps the fall arrester on the steel cable, and then locks the safety device. The fall arrester automatically follows the operation above or below the human body through the safety harness belt. Personnel, when the operator falls and falls, the safety rope will freely expand and contract with the human body during normal use. Under the action of the mechanism inside the device, it is in a half-tension state, so that the operator has no sense of care. In case of a fall, the speed of pulling out the safety rope is significantly accelerated, and the internal locking system of the device is automatically locked. Make the safety rope pull-out distance not more than 0.2 meters, the impact force is less than 2949N, no harm to people who have lost their feet. The anti-drop device is quickly locked due to the acceleration of gravity, and the steel cable is held by the card, thereby effectively preventing the human body from falling.
