Description

Technical Field

[0001] The invention relates to a method for building an elevator and to an elevator, wherein the elevator is preferably an elevator for vertical transport of passengers and / or freight. Background Art

[0002] Traditionally, elevators are built from components into a prefabricated shaft, or the shaft is manufactured simultaneously with the rest of the elevator. A disadvantage is that all elevator installation work carried out on the building site is time-consuming and complicates the logistics of the building site. A disadvantage is also that the exact positioning of the components requires a lot of adjustments on site. Despite the use of modular elevator solutions, in which the elevator is partially built from several modules, the known solutions are not good in terms of efficiency and rapidity and simplicity of the process as well as maintaining the use of normal elevator components and relative freedom to install the elevator on any type of building. Summary of the invention

[0003] The object of the present invention is to provide a method of building an elevator and an elevator to improve the efficiency and accuracy of elevator construction work. In particular, an object is to alleviate one or more of the above defined disadvantages of the prior art and / or problems discussed or suggested elsewhere in the specification.

[0004] Specifically, one object is to provide a solution with a high degree of ease to enable a complete and well-functioning elevator to be quickly formed from elevator installation materials after the elevator installation materials are brought to the construction site and quickly put into service without requiring excessive on-site installation and adjustment work. One object is to provide an elevator layout and structural aspects, such as materials and special component relationships, which together achieve the above objects by facilitating the simplicity and ease of the steps required to form a complete elevator and put it into service after the elevator installation materials are brought to the site.

[0005] In addition, the disclosed embodiments realize an elevator without a counterweight room while achieving the above-mentioned objectives.

[0017] In a preferred embodiment, the counterweight guide rail portions of the prefabricated hoistway modules are positioned in the prefabricated modules so that when the hoistway modules are stacked on top of each other, the counterweight guide rail portions of the prefabricated hoistway modules are vertically aligned to form one or more continuous vertical guide rail lines for guiding the counterweight.

[0018] In a preferred embodiment, each of the car guide rail sections is fixed to a horizontal beam of a frame of the prefabricated module, in particular to a horizontal beam of a beam frame or to a horizontal beam of a concrete frame, wherein the horizontal beam is embedded in concrete of the concrete frame, using at least one fixing bracket.

[0025] In a preferred embodiment, the beams of the beam frame are tubular metal beams. Thus, the beam frame is rigid and light, whereby large modules can be formed and lifted into place. This structure also reduces the forces to be withstood when stacking, so that the modules can be stacked high.

[0060] Figure 1 and Fig. 9Phases in an embodiment of a method for building an elevator are respectively illustrated. Figure 1 A first embodiment is shown in the figure, in which a metal beam frame F is used, Fig. 9 A second embodiment is illustrated, in which a concrete frame F' is used. In each case, at this stage of the method, a plurality of prefabricated hoistway modules A, B, C; A', B', C' are provided, which are to be stacked on top of each other. An elevator car 1 is also provided. Figure 1 and Fig. 9 In the embodiment of FIG. 1 , the elevator car 1 is in the shaft space S of a prefabricated shaft module A among the prefabricated shaft modules.

[0061] Each shaft module A, B, C; A', B', C' defines a shaft space S into which the entire elevator car 1 or at least its upper or lower end can be fitted so as to be movable. Therefore, the shaft space S in question is large enough to surround the entire elevator car 1 or at least its upper or lower end. In the method, the plurality of prefabricated modules A, B, C; A', B', C' are stacked on top of each other, such as Figure 2 As shown, the hoistway spaces S of the prefabricated modules A, B, C; A', B', C' are vertically aligned to form a continuous vertical elongated hoistway H, where the elevator car 1 can be installed to move. In addition, the method includes arranging the elevator car 1 to be vertically movable in the hoistway H.

[0062] Each of said prefabricated modules A, B, C; A', B', C' comprises a tubular frame F; F' surrounding the shaft space S of the module A, B, C; A', B', C', wherein the tubular frame F; F' forms the load-bearing structure of the module A, B, C; A', B', C' in question. The tubular structure of the frame F; F' enables it to transversely surround the shaft space S of the module A, B, C; A', B', C'. The tubular structure is advantageous because it increases the rigidity and integrity of the single module and of the modules A, B, C; A', B', C' produced by stacking.

[0063] In the stack, the multiple prefabricated shaft modules A, B, C; A', B', C' are stacked on top of each other so that the tubular frame F; F' of each prefabricated module A, B bears the weight of the tubular frames F; F' of all the prefabricated shaft modules B, C stacked on top of it.

[0064] exist Figure 1 and Fig. 9In the preferred embodiment presented, a plurality of prefabricated hoistway modules A, B, C; A', B', C' comprises a prefabricated top module C, a prefabricated pit module A and a prefabricated intermediate module B, in which the entire elevator car 1 can be installed and moved through them. The pit module A is first placed at the desired installation location of the elevator to be built. For example, the location can be inside a building under construction, inside an existing building, or next to the outer surface of the interior of a building under construction, inside an existing building. Afterwards, the prefabricated intermediate modules B and the top modules C are stacked one after another on top of it, so that the tubular frames F, F' of each prefabricated module A, B bear the weight of all the prefabricated hoistway modules B, C tubular frames F, F' stacked on top of it.

[0065] In the arrangement, the elevator car 1 is arranged to be vertically movable in the hoistway H along two guide rails for guiding the elevator car 1. Each of the prefabricated hoistway modules A, B, C; A', B', C' provided in the provision includes a guide rail section 8 for guiding the guide rail line of the elevator car 1. Each of the guide rail sections 8 is suitable for forming a part of a longer guide rail line for guiding the car 1. Each of the guide rail sections 8 (also called car guide rail sections) is fixed to the tubular frame F; F' using at least one fixing bracket 17. The car guide rail sections 8 of the prefabricated hoistway modules A, B, C; A', B', C' have been positioned in the prefabricated modules so that when the hoistway modules A, B, C; A', B', C' are stacked on top of each other, the guide rail sections 8 of the modules A, B, C; A', B', C' are vertically aligned to form one or more (two in the example) continuous vertical guide rail lines for guiding the elevator car 1.

[0066] exist Figure 1 and Fig. 9 In the embodiment of the present invention, the elevator E, E' to be built is a counterweight elevator. Therefore, the method also includes providing a counterweight 2, wherein the entire counterweight 2 or at least its upper or lower end can be assembled to move into the shaft space S of each shaft module A, B, C; A', B', C'. Therefore, the shaft space S in question is large enough to surround the entire elevator car 1 or at least its upper or lower end. In the step of arranging the elevator car 1 to be vertically movable in the shaft, the counterweight 2 is also arranged to be vertically movable in the shaft H (in particular along two guide rails for guiding the counterweight).

[0067] Each of the prefabricated hoistway modules A, B, C; A', B', C' provided in the provision comprises a guide rail section 9 for guiding two guide rail lines of the counterweight 2. Each of the guide rail sections 9 is adapted to form a portion of a longer guide rail line for guiding the counterweight 2. Each of the guide rail sections 9 (also referred to as counterweight guide rail sections) is fixed to the tubular frame F; F' using at least one fixing bracket 17. The counterweight guide rail sections 9 of the prefabricated hoistway modules A, B, C; A', B', C' have been positioned in the prefabricated modules so that when the hoistway modules A, B, C; A', B', C' are stacked on top of each other, the guide rail sections 9 of the modules are vertically aligned to form one or more (two in the example) continuous vertical guide rail lines for guiding the counterweight 2. The same fixing bracket 17 can be used to fix the guide rail section 8 of the elevator car 1 and the guide rail section 9 of the counterweight 2.

[0068] The elevator car 1 is at least partially located in the hoistway space S of one of the prefabricated modules A to be stacked, preferably in the pit module A. Likewise, the counterweight 2 is at least partially located in the hoistway space S of one of the prefabricated modules A to be stacked, preferably in the prefabricated pit module A.

[0069] exist Figure 1 and Fig. 9 In the preferred embodiment shown, the top module comprises a machine 13 for driving the hoisting ropes 21 .

[0070] exist Figure 1 In the embodiment of the present invention, the tubular frame F of each of the prefabricated modules A, B, C is a beam frame F. Figure 1 In the embodiment of the present invention, the beam frame F includes a horizontal beam 14a, a vertical beam 14b and an inclined beam 14c that are rigidly connected together. The beam includes four vertical angle beams 14b connected by the horizontal beam 14a, and a plurality of inclined beams 14c that extend at an inclined angle in a space defined by two vertical beams 14b and two horizontal beams 14a. The opposite ends of each inclined beam are attached to the vertical beam 14b and the horizontal beam 14a (preferably by welding). The four vertical angle beams are connected by the horizontal beam to form a rectangular cuboid structure.

[0071] Generally, the beams 14a, 14b, 14c are preferably tubular metal beams. Therefore, the beam frame F is rigid and lightweight, thereby allowing large modules to be formed, transported and lifted into place. The light weight reduces the forces to be borne when stacking, thereby allowing the modules to be stacked high.

[0072] In general, the beams 14a, 14b, 14c preferably have one or more planar sides, such as four planar sides as shown, thereby facilitating the securing of elevator components thereto.

[0073] Figure 4A preferred detail of the prefabricated top module C is illustrated. Figure 5 Picture shows Figure 4 The layout of the top module C. Figure 4 The prefabricated top module C illustrated in FIG. 1 comprises a guide rail section 8 for guiding two guide rail lines of the elevator car 1 and a guide rail section 9 for guiding two guide rail lines of the counterweight 2. The prefabricated top module C comprises a machine 13 for driving hoisting ropes 21 (shown in dotted lines).

[0074] The machine 13 for driving the hoisting ropes comprises a motor 18 and a drive wheel 19. The machine 13 is mounted on a guide rail section 8 of a guide rail line for guiding the elevator car 1 carried vertically by the guide rail section 8. Thus, the weight of the machine 13 and the load applied by the ropes 21 around the drive wheel 19 are carried by the guide rail section 8 and the entire weight of the machine 13 and the load applied by the ropes 21 around the drive wheel 19 can be at least partially transferred by the guide rail section to the guide rail section below it. The load applied by the ropes 21 around the drive wheel 19 is here formed partly by the weight of the ropes 21 and partly by the elevator units, for example by the car 1 and the counterweight 2 suspended therefrom. The total weight carried by the guide rail section 8 on which the machine is mounted is therefore large. Thus, the possibility that the guide rail line can at least partially carry the weight is advantageous in simplifying the installation of the guide rail section by means of a small number of compact and lightweight brackets.

[0075] The machine 13 is mounted on the rear side of the guide rail section 8 by one or more support brackets 20 on the guide rail section 8. Here, the rear side is the opposite side of the front side of the guide rail section 8, the front side being the side on which the elevator car 1 is arranged when viewed in the vertical direction, and the elevator car 1 is movable in the shaft guided by the guide rail line. The motor 18 and the drive wheel 19 are coaxial, and the drive wheel is fixedly connected to the rotor of the motor 18. As a result, they can be compactly arranged on the rear side of the guide rail section 8. The motor can be a flat motor, which refers to a motor whose axial dimension is significantly smaller than the radial dimension. Preferably, the size of the motor in its axial direction is substantially smaller than more than 50% of its size in its radial direction.

[0076] Each of said guide rail sections 8 for guiding the guide rail wire of the elevator car 1 is fixed to a horizontal beam 14a of the beam frame F (specifically using at least one fixing bracket 17).

[0077] The prefabricated top module C also includes rope fixing brackets 12. On each rope fixing bracket, the end of the lifting rope 21 can be fixed. Figure 4 As shown, the rope fixing bracket 12 (in Figure 4 and Figure 5The left side of the car guide rail section 8 is fixed to a fixing bracket 17, which is fixed to the car guide rail section 8 and the horizontal beam 14a of the beam frame F. This is advantageous because the car guide rail section 8 and the rope fixing bracket 12 are thereby positioned transversely relative to each other and relative to the beam frame F. In addition, the guide rail line can thereby at least partially carry the load applied by the rope 21 to the rope fixing bracket 12. Figure 4 As shown, the rope fixing bracket 12 (in Figure 4 and Figure 5 The right side of the elevator (see FIG. 1 ) is fixed to a horizontal beam 22 which is fixed to the car guide rail section 8 and the counterweight guide rail section 8, which connects them to each other. By means of the beam 22, the rope fixing brackets 12 in question can be placed relatively freely. This is also advantageous because the car and counterweight guide rail lines can thereby at least partially carry the loads applied by the ropes 21 to the rope fixing brackets 12. The ends of the hoisting ropes 21 are fixed to each of said rope fixing brackets 12.

[0078] exist Figure 4 In the embodiment of the present invention, the prefabricated top module C does not include a doorway leading away from the hoistway space S. Figure 4 In the embodiment of the present invention, the prefabricated top module C is lower than the elevator car 1. Figure 4 In the embodiment of the present invention, the prefabricated top module C thus forms a relatively low structure into which the car can be partially driven, at least in case the car or the counterweight moves beyond its predetermined uppermost position during transport use.

[0079] In the described arrangement of arranging the elevator car 1 and the counterweight to be vertically movable in the hoistway H, the elevator car 1 and the counterweight 2 are suspended using hoisting ropes 21 around the drive sheave 19 . Figure 6 The diagram shows preferred details of how the rope 21 is passed.

[0080] Figure 7 A preferred detail of the prefabricated intermediate module B is illustrated. Figure 7 The prefabricated intermediate shaft module B shown in the figure comprises a guide rail section 8 for guiding two guide rail lines of the elevator car 1 and a guide rail section 9 for guiding two guide rail lines of the counterweight 2. The prefabricated intermediate shaft module B comprises a doorway D2, which leads away from the shaft space S of the module in question, and a shaft door 6, which is used to openably cover the shaft doorway D2 at least partially. Since the shaft door 6 is included in the prefabricated intermediate module B, its most laborious installation work can already be completed at the factory where the module is manufactured. Thus, there is no need to carry out time-consuming work at the installation site, and the elevator can be installed quickly and with little interference with other operations on the construction site.

[0081] In the illustrated embodiment, the door 6 is a sliding door mounted on one or more door rails 10 mounted on the frame F of the prefabricated intermediate shaft module B. The door 6 is locked relative to the frame F of the prefabricated intermediate shaft module B during stacking.

[0082] Figure 8 Preferred details of the pre-pit module A are shown. Figure 8 The prefabricated intermediate pit module A illustrated in the figure comprises a guide rail section 8 for guiding two guide rail lines of the elevator car 1 and a guide rail section 9 for guiding two guide rail lines of the counterweight 2. The prefabricated pit module A preferably also comprises a doorway for leading out of the hoistway space S of the module in question, and a hoistway door for openably covering the hoistway doorway at least partially, although these are not Figure 8 Not shown in FIG.

[0083] The elevator car 1 and the counterweight 2 are located in a shaft space S of one of the prefabricated pit modules A. The prefabricated pit module A includes buffers 15, 16, including a buffer 15 for stopping the elevator car 1 from descending and a descending buffer 16 for stopping the counterweight 2.

[0084] exist Fig. 9 In an embodiment, the tubular frame F' of each of the prefabricated hoistway modules A', B', C' is a concrete frame F', which comprises concrete or reinforced concrete, which preferably forms more than 50% of the weight of the frame F'. The concrete frame F' comprises four vertical concrete walls rigidly connected together.

[0085] Figures 9 to 12 The diagram shows preferred details of the prefabricated modules A', B', C'. Each prefabricated module A', B', C' comprises a guide rail section 8 for guiding two guide rail lines of the elevator car 1 and a guide rail section 9 for guiding two guide rail lines of the counterweight 2. Each of the car guide rail sections 8, as well as each of the counterweight guide rail sections 9, is fixed to the concrete frame F' (specifically, by at least one fixing bracket 17). Fig. 9 In the embodiment of the present invention, each frame F' comprises one or more horizontal metal beams 23 embedded in its concrete. Each said metal beam 23 forms an integral part of the wall of the concrete frame F'. Each said guide rail section 8 for guiding the guide rail line of the elevator car 1 is fixed to the horizontal beam 23 of the frame F' of the prefabricated modules A', B', C' (in particular, by at least one fixing bracket 17).

[0086] The prefabricated top module C' comprises a machine 13 for driving the hoisting ropes accordingly, such as Figure 4 shown. Figure 6 A preferred detail is shown of how the rope 21 is passed.

[0087] Figure 6 The preferred layout of the top module C' is illustrated. The machine 13 for driving the hoisting ropes comprises a motor 18 and a drive wheel 19. The machine 13 is mounted on a guide rail section 8 of a guide rail line for guiding the elevator car 1 carried vertically by the guide rail section 8. Therefore, the weight of the machine 13 and the load applied by the ropes around the drive wheel 19 are carried by the guide rail section 8, and the entire weight of the machine 13 and the load applied by the ropes 21 around the drive wheel 19 can be transmitted at least partially by the guide rail section to the guide rail section below it. The load applied by the ropes 21 around the drive wheel 19 is here formed partly by the weight of the ropes 21 and partly by the elevator units, such as the car 1 and the counterweight 2 suspended therefrom. As a result, the total weight carried by the guide rail section 8 on which the machine is mounted is large. Therefore, the possibility that the guide rail line can at least partially carry the weight is advantageous for simplifying the installation of the guide rail section by a small number of compact and light-weight brackets.

[0088] The machine 13 is mounted on the rear side of the guide rail section 8 by one or more support brackets 20 on the guide rail section 8. Here, the rear side is the side opposite to the front side of the guide rail section 8, the front side being the side on which the elevator car 1 is arranged when viewed in the vertical direction, and the elevator car 1 is movable in the hoistway guided by the guide rail wire. The motor 18 and the drive wheel 19 are coaxial, and the drive wheel is fixedly connected to the rotor of the motor 18. As a result, they can be compactly placed on the rear side of the guide rail section 8. The motor can be a flat motor, which means a motor whose axial dimension is much smaller than the radial dimension.
