Abstract
Description
Technical Field
[0001] The invention relates to a method for building an elevator and a configuration changing device for changing the configuration of an elevator device previously used for transporting passengers and / or freight. The elevator is preferably an elevator for transporting passengers and / or freight. Background Art
[0002] This type of construction time elevator is known, also referred to as a jump-type elevator hereinafter, in which the bottom part of the elevator shaft has been transported for use when the upper part of the building and the shaft is still under construction or even does not exist. In this project, the upper part of the building and the top part of the elevator shaft can be built at the same time, because the elevator moving at the bottom part of the elevator shaft has served the people on the lower floors of the building being built. Usually, in a jump-type elevator, during the use of construction time, the elevator car moving at the lower part of the elevator shaft is supported and moved with a hoist supported on a machine room, which can be moved vertically in the elevator shaft. This type of jump-type elevator is also known, in which the hoist is mounted on a guide rail and is detachable for moving it upward by lifting. For example, in documents WO2010010226A1 and WO2021170847A1, different jump-type elevator solutions have been disclosed.
[0003] When a portion of the elevator shaft being constructed above the hoist has reached a sufficient stage of completion, the completed portion of the elevator shaft can be put into use. At this stage, a configuration change is performed, hereinafter also referred to as a "leap", in which the hoist is lifted higher in the elevator shaft. After this, the car can reach a higher position than before the leap and start serving additional floors. In addition, in the context of this configuration change, many other components are also lifted. Such components include the lifting ropes of the elevator device. A known way is to lift the lifting ropes together with the hoist without separating from the hoist. This has been achieved, for example, when the lifting ropes have rested on the drive pulley during lifting. The rise of the hoist pulls the lifting ropes upward with it. The lifting rope can extend through an openable rope clamping device into a rope supply storage. In this type of solution, before the leap, the rope clamping device is opened, which enables additional rope length to enter the system in the leap from the rope supply storage pulled by the upward movement of the hoist.
[0004] One disadvantage of the above-mentioned prior art solutions is that the hoisting step of the hoisting machine and the hoisting ropes is difficult, especially when the hoistway is narrow and / or the hoisting machine is located in a small space and / or the hoisting ropes pass through narrow vertical passages (e.g. near hoistway walls and guide rails). The large size and / or weight of the hoisting machine also cause said difficulties, especially when the ropes limit the freedom of the hoisting route of the hoisting machine and significantly increase the total weight to be lifted. Summary of the invention

[0086] Figure 1 The diagram illustrates the stages of a method for building an elevator according to an embodiment. The method comprises providing Figure 1 The elevator device A shown. The device A comprises one or more hoisting ropes 1, a hoisting machine 2, which is installed in a first position in a hoistway 3, and comprises an electric motor 2a and a drive pulley 2b for engaging the one or more hoisting ropes 1. The drive pulley 2b can be rotated by the electric motor 2a.
[0087] The arrangement A further comprises an elevator car 4 and a counterweight 5 in the elevator shaft 3, which are connected to each other by means of the one or more hoisting ropes 1.
[0088] Device A also includes an elevator control system 100 connected to the electric motor 2a, which is configured to control the movement of the elevator car 4 by controlling the rotation of the electric motor, preferably in response to a car call signal received by the elevator control system from one or more user interfaces located at one or more landings and / or inside the car 4.
[0089] Each of the one or more hoisting ropes 1 has a first section A and a second section B that are continuous with each other.
[0090] In device A, the first section A is on the first side of the driving pulley 2b ( Figure 1 The left side in the figure) leads downward from the driving pulley 2b to the car 4, and the second section B is on the second side of the driving pulley 2b ( Figure 1 The first section S1 leads from the driving pulley 2b on the right side of the driving pulley 2b downwards to the counterweight 5. The first section S1 leads from the driving pulley 2b on a first side of the driving pulley 2b to one or more pulleys 6a, 6b of a pulley arrangement 6 included in the car 4 and around said one or more pulleys 6a, 6b and from the pulley arrangement 6 to a rope fixing device 8 mounted stationary in the hoistway 3, wherein the end of the hoisting rope 1a is fixed at this rope fixing device 8, said end 1a also being referred to as the first end 1a. Said end is in particular the end of the first section S1.
[0091] The method comprises moving an elevator car 4 for transporting passengers and / or goods with a hoist 2, as indicated by arrow a1. The method comprises performing a configuration change after a period of time of said moving elevator car 4. Figures 2 to 13 The stages of configuration change of a method according to an embodiment are illustrated.
[0092] After the configuration change, the method comprises moving the elevator car 4 for transporting passengers and / or freight with the hoist 2. Fig.14 This is illustrated by arrow a2.
[0093] The configuration change enables the lifting range of the device A to reach higher in the hoistway 2. To this end, Figure 8 As shown, the configuration change includes lifting the hoist 2 and thereafter reinstalling it in the hoistway 3 to a second position higher than the first position, thereby increasing its lifting range to reach a higher position in the hoistway 2. This reinstallation is shown in FIG. Fig. 9 shown.
[0094] Said configuration change comprises detaching one or more hoisting ropes 1 from the hoisting machine 2 before said lifting of the hoisting machine 2 .
[0095] The separation preferably comprises removing tension from one or more lifting ropes 1. Figure 2As shown. The removal of tension preferably includes supporting the car 4 by a structure other than the lifting ropes 1, such as by fixedly anchoring the car 4 in the shaft 3. Thus, the separation can be performed when the car 4 is stationary and supported by a structure other than the lifting ropes 1, preferably fixedly anchored in the shaft 3. The anchoring can be implemented in different alternative ways. For example, it can include, for example, fixing the car 4 to the guide rail 21 or the shaft structure by an auxiliary hoist not shown. The removal of tension preferably also includes supporting the counterweight 5 by a structure 19 separated from one or more lifting ropes 1, such as by a counterweight buffer or another structure temporarily placed under the counterweight 5.
[0096] The separation consists in fixing, for each of the hoisting ropes 1, the second section S2 of the hoisting rope 1 to a structure 4 other than the hoisting machine 2 in the vicinity of the drive pulley 2b, so that the second section is supported by the structure 4 other than the hoisting machine 2. Figure 3 In the preferred embodiment shown, the other structure in the fixing is the car 4 and the fixing is performed by fixing devices 9 mounted on the car 4.
[0097] The separation also comprises attaching an auxiliary rope 7 to the end 1a of the lifting rope 1 for each of the lifting ropes 1. This has already been done in Figure 4 In the attachment, the end of the auxiliary rope 7 is attached to the end 1a of the lifting rope 1, in particular with a sleeve 19, the end extending inside the sleeve 19, in particular extending from opposite directions, and / or by splined ends. The sleeve 19 is preferably a tubular element, such as an aluminum tube or a belt twisted into a tubular shape around the end.
[0098] The separation also comprises, in particular after said fixing of the second section S2 and after said attachment, for each said lifting rope 1, pulling the lifting rope 1 so that the auxiliary rope 7 attached to the lifting rope 1 runs around said one or more pulleys 6a, 6b of the pulley arrangement 6. This has already been Figure 5 and Figure 6 The pulling can be done manually by a person standing on top of the car 4, for example.
[0099] This separation also comprises, for each of said hoisting ropes 1 , detaching the auxiliary rope 7 from the end 1 a of the hoisting rope 1 , in particular after said pulling. Figure 7The auxiliary rope is shown detached from the end 1a. The detachment preferably comprises, after said pulling and before said detachment, fixing the end of the auxiliary rope 7 for each said hoisting rope 1 by means of a fixing device 24 mounted on the car 4. Thus, the auxiliary rope 7 will be firmly held in its position after being pulled through the rope pulley arrangement 6. The opposite end of the auxiliary rope 7 is also preferably fixed, for example, by means of a fixing device 23 mounted on the car 4. The auxiliary rope 7 is pulled through the rope pulley arrangement 6 so that it passes around one or more pulleys 6a, 6b along the previous route of the hoisting rope 1. This facilitates that the auxiliary rope 7 can be used later to simply and quickly pull the hoisting rope 1 back to its original route. Thus, it is convenient that the hoisting rope 1 can be positioned to simply and quickly pass around one or more pulleys 6a, 6b after a configuration change.
[0100] The separation also comprises, for each of said hoisting ropes 1, moving the first section S1 past the driving pulley 2a, in particular by moving the first section S1 past the driving pulley 2a towards the second side of the driving pulley 2b. Figure 7 The operation of moving the first section S1 through the driving pulley 2a toward the second side of the driving pulley 2b continues until the entire first section S1 has been moved through the driving pulley 2a, in particular, to the second side of the driving pulley 2b.
[0101] This separation also comprises placing the first section S1 to be stored on the car 4, preferably in a coiled or coiled form.
[0102] Figure 8 A stage is illustrated in which the separation is completed and the lifting of the hoist 2 is being performed. Thereafter, the configuration change consists in reinstalling it in the hoistway 3 to a second position higher than the first one. Fig. 9 The lifting machine 2 is shown in the second position.
[0103] Generally speaking, it is preferred that in the device A, the rope 1 bypasses the driving pulley 2b via a passage 16 on the radial side of the rim of the driving pulley 1b. Components close to the passage 16 may be positioned so that they block the lifting rope 1 from being freely removed from the passage 16 by lifting the lifting rope 1 away from the loop of the driving pulley 2b. During the movement of the first section S1 past the driving pulley 2a, the first section S1 is moved through the passage 16.
[0104] Generally speaking it is preferred that in the device A one or more hoisting ropes 1, in particular the second section S2 thereof, extend via a releasable rope gripping device 10 into a rope supply storage 11, preferably in the form of one or more rope reels, from which additional lengths of hoisting ropes 1 can be taken when the configuration is changed. This is preferably implemented in such a way that the second section S2 leads from the driving pulley 2b on a second side of the driving pulley 2b downwards to the counterweight 5, more particularly to one or more pulleys of a pulley arrangement included in the counterweight 5, and around said one or more pulleys, and from the pulley arrangement of the counterweight to the releasable rope gripping device 10 and via the rope gripping device into the rope supply storage 11.
[0105] like Fig. 9 As shown, the configuration change includes lifting the car 4 after the hoist 2 is lifted. The configuration change includes releasing the releasable rope gripping device 10 at a suitable moment and moving an additional length of rope from the rope supply storage 11 through the releasable rope gripping device 10 and thereafter closing the releasable rope gripping device 10. Before lifting the car 4, Fig. 9 The release is performed in , so that the lifting of the car 4 can generate a pulling force to pull out the required length of rope from the rope storage.
[0106] The configuration change consists in moving, after the hoisting car 4, for each of the hoisting ropes 1, the first section S1 of the hoisting rope 1 past the drive pulley 2a, in particular from the second side towards the first side of the drive pulley 2b, in particular through the passage 16. This has already been Fig.10 Medium picture.
[0107] The configuration change consists in attaching an auxiliary rope 7 to the first end 1a of the hoisting rope 1 after said moving the first section S1 of the hoisting rope 1 past the driving pulley 2a, the auxiliary rope passing via the pulley arrangement 6. This has already been Fig.11 The attachment is performed similarly to reference Figure 4 as described.
[0108] The configuration change consists in pulling the auxiliary rope 7 after said attachment, so that the hoisting rope 1 attached to the auxiliary rope, in particular said first section S1, runs around said one or more pulleys 6a, 6b of the pulley arrangement 6. This has already been done in Fig.12 Medium picture.
[0109] The configuration change consists in detaching the auxiliary rope 7 from the first end 1a of the hoisting rope 1 after said pulling, and fixing the first end 1a to a rope fixing device 8 which is stationarily installed in the hoistway 3. This has already been done in Fig.13The configuration change comprises, after said fixing of the first end 1a to the rope fixing device 8, releasing said fixing device 9 mounted on the car 4. Thereafter, the method comprises moving the elevator car 4 for transporting passengers and / or goods with the hoist 2, such as Fig.14 As shown by arrow a2.
[0110] In a preferred embodiment, in the device A, the rope 1 bypasses the drive pulley 2b via a passage 16 on the radial side of the rim of the drive pulley 1b. Components close to the passage 16 can be positioned so that they block the lifting rope 1 from being freely removed from the passage 16 by lifting the lifting rope 1 away from the ring of the drive pulley 2b. Fig.16 The preferred details of the hoisting machine installed in the first position and in the second position are shown. The hoisting machine 1 comprises one or more components 17, 18 on the radial side of the rim of the driving pulley 2b, each of the hoisting ropes 1 passing around the driving pulley 2b via a passage 16 radially between the rim of the driving pulley 2b and the one or more components 2a, 2b, 17, 21, preferably comprising
[0111] A jump guard or rope position sensing member 18; and / or
[0112] lifting frame member 17; and / or
[0113] The hoist is mounted on the guide rail 21 via a support bracket (not shown).
[0114] exist Fig.16 In the embodiment of the invention, said passage 16 is tubular and is continuously surrounded by the parts 2a, 2b, 17, 21, in particular so that the removal of the rope is blocked in its transverse direction.
[0115] like Fig.15 As shown, the device A preferably comprises one or more guide rails 21 , 22 in the hoistway 3 for guiding the car 4 and / or the counterweight 5 .
[0116] like Fig.15 As shown, the method comprises, in particular during the movement of an elevator car 4 for transporting passengers and / or goods with the hoist 2, performing construction works in the hoistway 3 above the level of the hoist 2 installed in the first position. The construction works preferably comprise placing one or more additional guide rail sections 21a, 22a on top of one or more of the guide rails 21, 22 for extending the one or more guide rails higher in the hoistway 3.
[0117] like Fig.15 and Fig.16As shown, the hoist 2 is preferably mounted in said first position on the guide rail 21, preferably on the rear side of the guide rail 21 for guiding the elevator car 3, which is the opposite side on which the car 4 is arranged, and the driving pulley 2b is preferably located between the guide rail 21 and the motor 2a of the hoist 2. In an installation where the hoist has such positioning, the advantages of this method are particularly significant, because the lifting of the hanging rope and the hoist 2 is relatively limited.
[0118] Generally speaking, in the method, each of the movements includes controlling the movement of the car 4 by the elevator control system 100 in response to a car call signal received by the elevator control system 100 from one or more user interfaces 101 located at one or more landings L and / or inside the car 3.
[0119] In addition to illustrating one stage in the process, Figure 8 A configuration change device AC according to an embodiment is illustrated, in particular in a method for changing the configuration of a lift device A previously used for transporting passengers and / or cargo, comprising a hoistway 3; one or more hoisting ropes 1; a lift car 4 and a counterweight 5 in the hoistway 3, the car 4 comprising a pulley arrangement 6, the pulley arrangement comprising one or more pulleys 6a, 6b; and a hoist 2. The hoist 2 comprises a drive pulley 2a for engaging the one or more hoisting ropes 1, and an electric motor 2a for rotating the drive pulley 2b. The configuration change device AC also comprises a lifting device 13 connected or at least connectable to the hoist 2 for lifting the hoist higher in the hoist 3.
[0120] The configuration change device AC further comprises one or more auxiliary ropes 7, wherein the one or more hoisting ropes 1 are separated from the hoisting machine 2, a section S2 of each hoisting rope 1 is fixed to a structure 4, preferably a car 4, near the driving pulley 2b, instead of the hoisting machine 2, so that support for the section S2 is provided by the structure 4 instead of the hoisting machine 2, and wherein the one or more auxiliary ropes 7 are passed around one or more pulleys 6a, 6b of the pulley arrangement 6. The one or more auxiliary ropes 7 passed around the one or more pulleys 6a, 6b facilitate the one or more auxiliary ropes to be used later to pull the hoisting rope (one or more) 1 around the one or more pulleys 6a, 6b simply and quickly. Therefore, it is facilitated that the hoisting ropes 1 can be positioned to be passed around them simply and quickly after the configuration change.
[0121] The fixing is more particularly carried out in the embodiment shown in such a way that the section S2 of each hoisting rope 1 is fixed in the vicinity of the driving pulley 2 b , more particularly to the car 4 by means of a fixing device 9 mounted on the car 4 .
[0122] The configuration change device AC is advantageous because it facilitates that the hoisting machine and the hoisting ropes can be lifted separately. In this way, in the lifting of the hoisting machine and the hoisting ropes, the degree of freedom of the lifting route is increased. For example, the hoisting machine can be lifted without restrictions caused by the ropes hanging on it.
[0123] Preferred further details of the apparatus AC have been already mentioned in reference Figure 8 discussed in the context of the method.
[0124] In the configuration change device AC, a further section S1 of each of the hoisting ropes 1 is stored on the car 4 , preferably in a coiled or wound form, and is detached from the auxiliary ropes 7 .
[0125] Advantageously, if Figure 8 As shown, in the configuration change device AC, the one or more lifting ropes 1 do not pass around the one or more pulleys 6a, 6b of the pulley arrangement 6. The lifting rope 1 does not need to pass through this route because the auxiliary rope 7 can be used to pull the lifting rope 1 through the pulley arrangement 6. Therefore, the lifting rope 1 can be positioned to be easily moved so as to pass through the driving pulley later when necessary. In addition, as shown in FIG. Figure 8 As shown, in the configuration change device AC, it is advantageous that the one or more lifting ropes 1 are not attached to the one or more auxiliary ropes 7. Attachment is not necessary, so the lifting rope 1 can be ready to be easily moved to pass through the drive pulley later when needed.
[0126] In the configuration change device AC, the car 4 is stationary and supported by a structure other than the hoisting ropes 1, which is preferably fixedly anchored in the hoistway 3. The counterweight 5 is supported by a structure 19 separate from the hoisting rope or ropes 1, such as by a counterweight buffer 19 or another structure temporarily placed under the counterweight 5, and / or the car 4 is supported by a structure other than the hoisting ropes 1, such as by being fixedly anchored in the hoistway 3. This is as shown in FIG. Figure 3 shown.
[0127] The configuration changing device AC comprises Figure 1 The elevator control system 100 shown in FIG. Figure 8 It is not operational during the configuration change phase and is configured to control the movement of the elevator car 4, in particular in response to a car call signal received by the elevator control system from one or more user interfaces located at one or more landings and / or inside the car 4.
[0128] The configuration change device AC comprises a releasable rope clamping device 10 and a rope supply storage 11. One or more hoisting ropes 1 extend via the releasable rope clamping device 10 into a rope supply storage 11, preferably in the form of one or more rope reels, from which additional lengths of hoisting ropes 1 can be taken when the configuration is changed. These preferred further details are as follows Figure 3 shown.
[0129] Generally, as shown, the suspension ratio of the car 4 and the counterweight 5 may be 2: 1. However, alternatively, some other suspension ratio may be used, such as 1: 1 or 4: 1, for example, or any combination of the above suspension ratios.
