Elevator system and method for constructing such an elevator system
An elevator system arranged in an elevator shaft of a building in the construction phase grows with the building using a lifting process. The system includes a machine platform with an elevator drive machine and an elevator car suspended on the machine platform by a carrier. The elevator car is raised during the lifting process by a lifting device. The elevator system also includes an assembly platform that can be mechanically moved in relation to the machine platform along the elevator shaft. The lifting device includes a drive arranged on the machine platform and is also used to move the assembly platform.
1. An elevator system arranged in an elevator shaft of a building in a construction phase, the elevator system growing with an increasing height of the building by using at least one lifting process, comprising:
a machine platform including an elevator drive machine;
an elevator car suspended on the machine platform by a bearing means, wherein the machine platform and elevator car can be raised in the elevator shaft during the at least one lifting process;
a lifting device for raising the machine platform and the elevator car suspended on the machine platform;
an assembly platform that can be mechanically moved relative to the machine platform along a portion of the elevator shaft; and
wherein the lifting device includes a drive arranged on the machine platform and connected to the assembly platform for moving the assembly platform in the elevator shaft.
2. The elevator system according to claim 1 where in the drive of the lifting device is a continuous cable winch.
3. The elevator system according to claim 1 wherein the machine platform has adjustable support means for temporarily immovably supporting the machine platform in the elevator shaft.
4. The elevator system according to claim 1 wherein the assembly platform is arranged, until an end of its use in the elevator system, between the machine platform and a protective platform in the elevator shaft, the protective platform being a bearing structure supporting the raising of the machine platform and the assembly platform by the lifting device.
5. The elevator system according to claim 1 wherein the lifting device has a connecting hook for releasably connecting the lifting device to the machine platform or to the assembly platform.
6. The elevator system according to claim 5 wherein the lifting device includes a block and tackle having a reeving greater when the machine platform is being raised than when the assembly platform is being held and adjusted.
7. The elevator system according to claim 5 wherein the lifting device includes a block and tackle having a stationary roller block, a free roller block and a block and tackle cable, the connecting hook being on the free roller block.
8. The elevator system according to claim 7 wherein the stationary roller block is immovably fastened to a protective platform arranged in or above the elevator shaft, the protective platform being a bearing structure.
9. The elevator system according to claim 7 wherein the stationary roller block includes a roller, a cable line of the block and tackle cable extending from the roller to the drive of the lifting device that is arranged on the machine platform.
10. The elevator system according to claim 7 including a cable reservoir for the block and tackle cable arranged on the machine platform.
11. The elevator system according to claim 7 wherein at least one portion of the block and tackle cable that extends between the stationary roller block and the free roller block and/or a portion of the block and tackle cable that extends between the stationary roller block and the drive of the lifting device is guided through an opening in a base of the assembly platform when the machine platform is suspended on the lifting device.
12. The elevator system according to claim 5 including a ring into which the connecting hook can be hooked is arranged on the machine platform, and/or a ring into which the connecting hook can be hooked is arranged on the assembly platform.
13. The elevator system according to claim 1 including a protective roof arranged on and covering the machine platform above the elevator drive machine.
