Construction arrangement of an elevator
A construction arrangement of an elevator including a hoistway; a protection deck mounted inside the hoistway for protecting the portion of the hoistway below it from falling objects; wherein the protection deck includes a cover extending across the hoistway covering the hoistway such that it blocks objects from falling into the hoistway below it; and a frame mounted on stationary structures of the hoistway; and a hoisting apparatus for hoisting construction material below the protective deck. The hoisting apparatus is supported by the protective deck, the hoisting apparatus includes a hoisting machine mounted on protection deck, and a flexible tension member movable with the hoisting machine.
1. A construction arrangement of an elevator comprising:
a hoistway; and
a protection deck mounted inside the hoistway for protecting a portion of the hoistway below the protection deck from falling objects;
wherein the protection deck comprises
a cover extending across the hoistway and covering the hoistway such that the cover blocks objects from falling into the hoistway below the protection deck;
a frame mounted on stationary structures of the hoistway; and
a hoisting apparatus for hoisting construction material below the protection deck;
wherein the hoisting apparatus is supported by the protection deck, the hoisting apparatus comprising a hoisting machine mounted on the protection deck and a flexible tension member movably driven by the hoisting machine, and
wherein the protection deck comprises a supporting beam connected pivotally to the frame, and a diverting wheel mounted on said supporting beam, the flexible tension member being guided to pass from the hoisting machine to the diverting wheel, over the diverting wheel and from the diverting wheel downwards in the hoistway.
2. An arrangement according to claim 1 , wherein the supporting beam is connected to the frame pivotally around a vertical axis and/or around a horizontal axis relative to the frame.
3. An arrangement according to claim 2 , wherein the diverting wheel is supported by the supporting beam at a distance from said vertical axis whereby when the supporting beam is pivoted around said vertical axis, the diverting wheel moves along a circular path around said vertical axis at the distance thereof.
4. An arrangement according to claim 2 , wherein the diverting wheel is supported by the supporting beam at a distance from said horizontal axis whereby when the supporting beam is pivoted around said horizontal axis, the diverting wheel moves along a circular path around said horizontal axis at the distance thereof.
5. An arrangement according to claim 2 , wherein a location of the diverting wheel relative to the frame is adjustable by pivoting the supporting beam around said vertical axis and/or said horizontal axis.
6. An arrangement according to claim 2 , wherein the protection deck comprises a second diverting wheel for guiding the flexible tension member to pass from the hoisting machine to the diverting wheel.
7. An arrangement according to claim 6 , wherein the hoisting machine is higher than the diverting wheels and an upper face of the cover, and the flexible tension member is guided to pass from the hoisting machine to the second diverting wheel, to pass under the second diverting wheel, and from the second diverting wheel to pass to the diverting wheel, over the diverting wheel and from the diverting wheel downwards in the hoistway.
8. An arrangement according to claim 1 , wherein the hoisting machine is higher than an upper face of the cover.
9. A construction arrangement of an elevator comprising:
a hoistway; and
a protection deck mounted inside the hoistway for protecting a portion of the hoistway below the protection deck from falling objects;
wherein the protection deck comprises
a cover extending across the hoistway and covering the hoistway such that the cover blocks objects from falling into the hoistway below the protection deck;
a frame mounted on stationary structures of the hoistway, the cover being directly mounted on the frame; and
a first hoisting apparatus for hoisting construction material below the protection deck;
wherein the first hoisting apparatus is supported by the protective deck, the first hoisting apparatus comprising a first hoisting machine mounted on the protection deck, a first diverting wheel supported by the protection deck, and a first flexible tension member movably driven by the first hoisting machine, the first diverting wheel for guiding and supporting the first flexible tension member, and
wherein the construction arrangement further comprises a second hoisting apparatus for hoisting a load below the protective deck, the second hoisting apparatus including a second hoisting machine mounted on the load, a second diverting wheel supported by the protection deck, and a second flexible tension member movably driven by the second hoisting machine.
10. An arrangement according to claim 9 , wherein
the second flexible tension member includes a first end movably coupled to the second hoisting machine and a second end fixedly attached to the load, and the second flexible tension member is arranged to pass over the second diverting wheel.
11. An arrangement according to claim 9 , wherein the first hoisting machine is higher than an upper face of the cover.
12. An arrangement according to claim 9 , further comprising an elevator car mounted lower than the protection deck.
