Problems solved by technology
[0003] At present, for broken wires, if the broken wires are found during the maintenance process, if the broken wires are not serious, they will not be replaced directly, but the number of inspections will be increased until they are replaced. Basically, people only check the number of broken wires based on experience, and The elevator shaft is relatively dark, and it is inconvenient to accurately penetrate the broken wire book, and when the broken wire phenomenon occurs, there may also be broken wires inside the traction rope, which is inconvenient to observe, resulting in safety hazards in the traction rope

Embodiment Construction
[0045] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0046] A kind of elevator maintenance technology, comprises the steps:
[0047] Step 1: Broken wire breakpoint detection; the traction rope 1 is composed of multiple steel wires, and the phenomenon of broken wires in the traction rope 1 is that some steel wires break, and the broken steel wires completely lose their tensile effect at the broken wire point, and the steel wire breaks Finally, the broken wire point forms two steel wire ends. Since the overall length of the traction rope 1 is relatively long, when detecting the broken wire point, people use cotton yarn to form a ring and fix it on the outside of the traction rope 1, and people can directly hold the ring. Shaped cotton yarn, the ring-shaped cotton yarn can also be fixed by a fixing tool, and the elevator is running, so that the traction rope 1 and the ring-shaped cotton yarn move relatively. When...

The invention discloses an elevator maintaining process and belongs to the technical field of elevators. Awire breaking point is used as a center, upward extending is performed by at least 1 cm, downward extending is performed by at least 1 cm, and a detection interval is formed; a thermal shrinkage rubber sheet is winded on the detection interval by at least one circle, fixed, subjected to thermal shrinkage and taken down, then the perimeter of the wire breaking point is measured, after one re-maintaining period, the thermal shrinkage rubber sheet is winded on the detection interval by at least one circle, fixed, subjected to thermal shrinkage and taken down, and then the perimeter of the wire breaking point is measured for comparison; whether replacement is performed or not is determinedaccording to the perimeter change conditions, and the advantage that the condition of the wire breaking point of a hoist rope is judged correctly during maintenance is achieved.
Description
technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator maintenance process. Background technique [0002] Elevator, as a modern mechanical carrier, has become one of the essential equipment in people's daily life, and is widely used in shopping malls, high-rise office buildings and high-rise residential buildings. However, as a means of transportation, the elevator itself has certain dangers when it travels between high-rise buildings and the ground. Therefore, regular inspection and maintenance are required to ensure the normal operation of the elevator and the safety of passengers and goods. Among them, the traction elevator drives the car through the traction rope, fixed pulley and movable pulley. Usually, the traction rope is a group of multiple strands, and the traction rope will be worn or broken after working for a period of time. In order to ensure the safety of the elevator operation, the elevator needs to be ...
