AI Technical Summary
When the machine room of the Yuesheng elevator is located inside the core tube, the steel platform workers have to climb temporary stairs, which increases the danger. The relocation of components at the top of the shaft requires additional elevator downtime, and the components need to be dismantled and relocated after the machine room is completed, which reduces construction efficiency.
Design a step-up elevator system, including a steel platform, a lifting system, an elevator machine room, a traction wire rope feeding and receiving mechanism, and a rope sheave system. The steel platform is supported by the steel platform and the lifting system raises and lowers the steel platform, which in turn moves the elevator machine room. The traction wire rope and cable are automatically released, and the car and counterweight are aligned in the machine room, reducing downtime.
This allows workers on the steel platform to safely and quickly reach the top, reducing downtime, saving materials and time, and improving construction efficiency.

Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to elevator technology, in particular to a leap elevator and a leap method thereof. BACKGROUND
[0002] In the past, construction materials, equipment and personnel were transported by a construction site hoist installed outside the construction site. When the construction inside the construction site is close to completion, an elevator shaft is built for the elevator to be actually used in the future. This method increases the completion time of the building and the cost of construction materials. Therefore, the leap elevator technology is developed to solve the above problems. The leap elevator can gradually increase the range of elevator service by raising the car in the elevator shaft to be actually used in the future as the number of floors of the building progresses during the construction of the building. When the building construction reaches the highest floor, only the final adjustment is needed to complete the construction of the elevator, which greatly reduces the completion time of the building and saves construction materials. In addition, the operating speed of the construction site hoist is usually slower. The leap elevator can increase the speed by 4-6 times compared to the traditional hoist, which can significantly improve the construction efficiency.
[0003] The leap elevator is installed at the beginning of the construction (when the foundation construction is at a lower floor stage) and temporarily put into use as a device for transporting construction personnel (and engineering materials). As the foundation construction progresses, the height of the building increases, and the machine room of the elevator is raised to a higher position to increase the highest serviceable floor, so that it can serve more floors.
[0004] Currently, the machine room of the leap elevator is generally arranged below the construction work platform (i.e. steel platform) of the core tube. This brings the following problems. First, the highest serviceable floor of the elevator is still several dozen meters away from the highest work plane of the construction. The workers on the steel platform have to climb a long temporary staircase to reach the construction area, which increases the risk of construction work. Second, the components such as the top limit switch of the shaft need to be moved to a new position after the machine room is raised, which increases the downtime of the elevator during the leap. Finally, after the final machine room construction of the elevator is completed, the elevator machine room in the core tube needs to be removed and the main machine, control cabinet, speed limiter and other components need to be moved to the final machine room to convert into an officially used elevator, which reduces the efficiency of the construction site.
