Description

Technical Field

[0001] This invention relates to rope anchors for one or more ropes used in elevators, and to elevator devices and methods for constructing elevators. The elevator is preferably an elevator used for transporting passengers and / or goods. Background Technology

[0002] Regarding so-called skip-lift elevators, the lower portion of the elevator shaft is put into use before the building is completed. In this case, the upper portion of the building and the top portion of the elevator shaft can be constructed simultaneously with the elevator moving in the lower portion of the elevator shaft, already serving people on the lower floors of the building under construction. Typically, in a skip-lift elevator, the elevator car moving in the lower portion of the elevator shaft is supported and moved along with the hoist during the construction period, and the installation position of the hoist can be changed to a higher position during this process. The hoist is usually installed via a machine room that can move vertically within the elevator shaft, or alternatively, it is installed on some other movable structure or directly on the shaft structure, such as on guide rails or their supports.

[0003] The car is typically suspended and moved by ropes during its use to transport passengers and / or goods, with the ropes looping around the drive wheel of the hoist.

[0004] When the elevator shaft under construction above the hoist level has reached a fully completed stage, the completed portion of the elevator shaft can be put into service. At this stage, a "jump" is performed, in which the hoist, for example along with the structure that mounts it in the shaft, is lifted higher within the elevator shaft. The car can then travel to a higher position than before the jump and begin serving additional floors. During the lifting, additional sections of the rope can be supplied from the rope supply reservoir via a releasable anchor by means of the tension caused by the lifting. The anchor is always in the form of a clamp.

[0005] One drawback of the existing technology is that the clamping structure is difficult to design to clamp reliably and be easy to use in rope supply. Summary of the Invention

[0006] The object of this invention is to introduce a rope anchor for one or more ropes for an elevator, an elevator assembly, and a method for constructing an elevator, which improves the clamping reliability and ease of use in rope supply.

[0007] One objective is to introduce a solution that addresses one or more of the problems defined above in the prior art and / or the disadvantages discussed or implied elsewhere in the specification.

[0008] One objective is to provide a solution that facilitates the construction of an elevator car that moves within the elevator shaft, while the upper portion of the elevator shaft or its components are being built to serve people on the lower floors of a building under construction.

[0009] One objective is to facilitate the quick and easy operation of rope anchors so that ropes can pass through them.

[0010] A novel rope anchor for anchoring one or more ropes in an elevator is proposed, comprising at least:

[0011] A wedge-shaped housing comprising a conical nest shaped to have a narrow end opening toward a first direction and a wide end opening toward a second (opposite) direction; and

[0012] One or more wedge-shaped members installed in a conical nest for wedging against a rope passing through the conical nest; and

[0013] One or more spring members, for actuating and / or arranged to actuate one or more wedge-shaped members toward the narrow end of a conical nest; and

[0014] A release mechanism that can be actuated to move one or more wedge-shaped members toward the wide end of the conical nest.

[0015] This solution can achieve one or more of the aforementioned objectives.

[0016] The following describes further details of preferred rope anchors, which can be combined with rope anchors individually or in any combination.

[0017] In a preferred embodiment, the release mechanism includes a rotatable actuating member that is rotatable to move one or more wedge-shaped members toward the wide end of the conical nest.

[0018] In a preferred embodiment, the rope has a circular cross-section.

[0019] In a preferred embodiment, each of the wedge-shaped members includes a rope groove for receiving a rope. The rope groove preferably includes two arcuate sides for supporting opposing arcuate sides of the rope, the rope having a circular cross-section.

[0020] In a preferred embodiment, the rope groove is an undercut rope groove. Specifically, an undercut rope groove includes a bottom recess for creating space where a rope disposed in the rope groove will not reach the bottom of the rope groove. The recess is empty or alternatively filled with an elastic material, such as an elastomeric pad.

[0021] In a preferred embodiment, each wedge-shaped member is movable along the inner surface of the conical nest toward the narrow end and back toward the wide end.

[0022] In a preferred embodiment, the rope anchor includes two wedge-shaped members with a compression gap passing between them, through which the rope can be configured to pass.

[0023] In a preferred embodiment, the rope anchor includes a sliding bearing disposed between the wall of the wedge-shaped housing and each of the wedge-shaped members. The sliding bearing facilitates easy movement of the wedge towards the narrow end for wedging and easy movement towards the wide end for anchor release.

[0024] In a preferred embodiment, the sliding bearing is made of a different material than the walls of the wedge-shaped housing and each of the wedge-shaped members. Preferably, the sliding bearing comprises plastic, most preferably PTFE, but other plastics may be used alternatively.

[0025] In a preferred embodiment, the sliding bearing is a strip-shaped component. Preferably, the strip-shaped component has a thickness of less than 5 mm, a length of more than 5 cm, and a width of more than 1 cm. Preferably, the contact length between the strip and the wedge-shaped housing and the wedge-shaped component is also greater than 5 cm.

[0026] In a preferred embodiment, the wedge-shaped housing and each of the wedge-shaped members are made of metal. Preferably, the rope anchor includes a non-metallic sliding bearing disposed between the wall of the wedge-shaped housing and each of the wedge-shaped members. This facilitates easy movement of the wedge-shaped members, even though the wedge-shaped housing and each of the wedge-shaped members are made of metal.

[0027] In a preferred embodiment, the release mechanism includes

[0028] A pushing member that is movable to push one or more of one or more wedge-shaped members mounted in a conical nest toward the wide end;

[0029] A rotatable actuating component that is connected to a driving component by means of force transmission;

[0030] The pushing member can be moved by rotating the actuating member [that is, pushing one or more of the one or more wedge-shaped members installed in the conical nest toward the wide end].

[0031] In a preferred embodiment, the rotatable actuating member includes a cam head that can be rotated by actuation of the actuating member to force the pushing member to move to push the one or more wedge-shaped members mounted in the conical nest toward the wide end.

[0032] In a preferred embodiment, the cam head can be rotated by actuation of the actuating member to press against the mating member, thereby forcing the actuating member to move relative to the mating member.

[0033] In a preferred embodiment, the movement of the actuating member relative to the mating member is arranged to move the pushing member to push the one or more wedge-shaped members mounted in the conical nest toward the wide end.

[0034] In a preferred embodiment, the rope anchor includes a frame, and the mating member is immovable relative to the frame, while the actuating member is movable and rotatable relative to the frame in its radial direction.

[0035] In a preferred embodiment, the release mechanism includes one or more transmission members located between a rotatable actuating member and a pushing member for transmitting movement of the rotatable actuating member to the pushing member, causing it to move to push the one or more wedge-shaped members.

[0036] In a preferred embodiment, the actuating member and the pushing member are located on opposite sides of the wedge-shaped housing.

[0037] In a preferred embodiment, the actuating member is positioned on one side of the wedge-shaped housing with the nested wide end open toward that side, and the pushing member is positioned on one side of the wedge-shaped housing with the nested narrow end open toward that side.

[0038] In a preferred embodiment, the transmission member includes a carrier member that carries the actuating member, and one or more elongated rods arranged to transmit movement of the actuating member to the carrier member. The one or more elongated rods extend from a first side of the wedge-shaped housing to a second side of the wedge-shaped housing.

[0039] In a preferred embodiment, the rotatable actuating member comprises a hexagonal head. Therefore, it can be easily rotated, for example, using a bolt wrench or other equivalent tool.

[0040] In a preferred embodiment, the rope anchor includes one or more guide rollers for guiding the rope into the wide end of the tapered nest, particularly from the wide end of the nest toward the side of the housing where it is open. Specifically, the one or more guide rollers include guide rollers for acting on a portion of the rope that extends from one side of the housing toward which the wide end of the nest is open.

[0041] In a preferred embodiment, the one or more guide rollers include a guide roller that is higher than the tapered nest when the narrow end is lower than the wide end.

[0042] In a preferred embodiment, the rope anchor includes a releasable rope locking member mounted on the frame [for locking one or more ropes that are immovable relative to the frame, including at least the ropes]. The locking member is arranged to act on the portion of the rope to be locked, extending from one side of the housing into the nest, the wide end of which is open towards that side. This is advantageous because during the elevator's operational use, the rope portion is not tensioned by the elevator's movable load, which is the elevator or counterweight. However, the rope portion may become tensioned due to the rope's weight, which could pull the rope, causing the wedging effect to be harmfully negated and / or making it difficult to control the rope's balance and movement in certain situations after releasing the wedging. Preferably, the rope locking member includes two compression members on opposite sides of each rope to be locked, preferably movable toward each other by a screw-on fastening member, such as a screw-on fastening member. The screw-on fastening member preferably includes, for example, at least one bolt and one nut.

[0043] In a preferred embodiment, the rope locking component further includes one or more springs located between the two compression members, which elastically resist movement of the two compression members toward each other.

[0044] In a preferred embodiment, the screw-on fastening member includes a plurality of bolts extending through two compression members, and nuts that can be fastened to the bolts. Furthermore, the screw-on fastening member preferably also includes disc springs stacked between each nut and the compression member to be elastically compressed when the screw-on fastening member is tightened.

[0045] A new elevator arrangement is also proposed, including an elevator car in a shaft and a rope anchor including a rope connected to the elevator car and an anchoring rope, as described anywhere above.

[0046] This solution can achieve one or more of the aforementioned objectives.

[0047] The following describes preferred further details of the elevator installation, which can be combined with the elevator installation alone or in any combination.

[0048] In a preferred embodiment, the elevator car is used to transport passengers and / or goods, particularly when the hoist is in the first position I. This use is preferably as defined with reference to the first and / or second uses in this application.

[0050] In a preferred embodiment, the rope passes around the drive wheel of a hoist movably mounted at a first location in the shaft.

[0051] In a preferred embodiment, the elevator assembly includes a lifting device for lifting the hoist to a second position [II] in the shaft, which is higher than the first position [I], and / or for lifting the anchor higher in the shaft.

[0052] In a preferred embodiment, the rope enters from the rope supply memory into the wide end of the conical nest, passes through the conical nest, exits from the narrow end of the conical nest, and reaches the elevator car.

[0053] In a preferred embodiment, each of one or more wedge-shaped members is wedged against a rope passing through a conical nest.

[0054] In a preferred embodiment, the rope anchor is positioned such that the narrow end is lower than the wide end.

[0055] In a preferred embodiment, the rope storage is below the rope anchor, and the rope passes upward from the rope supply storage, over the guide roller mounted above the conical nest, and downward to the rope anchor.

[0056] In a preferred embodiment, the rope supply storage is located at least 10 meters below the rope anchor. The rope supply storage preferably comprises one or more rope reels.

[0057] In a preferred embodiment, the elevator assembly includes a releasable rope locking component mounted on a frame, which is arranged to lock at least one or more ropes, including the ropes, that are immovable relative to the frame. The locking component is specifically arranged to act on a portion of the rope to be locked, which extends from one side of the housing into a nest, the wide end of the nest being open toward that side.

[0058] A new method for constructing elevators is also proposed, which includes providing an elevator assembly as defined anywhere above, and

[0059] The elevator car is used to transport passengers and / or goods when the hoist is in the first position [I];

[0060] The construction work is performed when the hoist is in the first position [I]; and thereafter

[0061] The release anchor includes an actuation release mechanism to move one or more wedge-shaped members toward the wide end of the conical nest; and thereafter

[0062] The hoist is raised and installed in a second position (II) above the first position (I), the method comprising supplying an additional portion of the rope from a rope supply memory via a released anchor during the lifting, for example by means of the tension caused by the lifting; and thereafter

[0063] Re-anchoring the rope with an anchor, the re-anchoring including actuating the release mechanism in a reverse manner to allow one or more springs to move one or more wedge members toward the narrow end of the conical nest; and thereafter

[0064] The elevator car is used (secondary use) to transport passengers and / or goods when the hoist is in the second position (II).

[0065] This solution can achieve one or more of the aforementioned objectives.

[0086] The above aspects, features and advantages of the present invention will become apparent from the accompanying drawings and related detailed description. Detailed Implementation

[0087] Figure 1 A first embodiment of a rope anchor A for anchoring one or more ropes R of an elevator is shown. Figure 2 The rope anchor A and the rope R anchored by it are shown. The rope R has been partially illustrated.

[0088] Rope anchor A includes a wedge-shaped housing 1, the wedge-shaped housing 1 including a conical nest N, which is shaped to have a first direction [ Figure 2The narrow end E1 of the opening [downward] and the direction towards the second direction [ Figure 2 [Center upward] Wide end E2 with opening; and one or more wedge-shaped members 2, 3, which are installed in the conical nest N for wedging against the rope R passing through the conical nest N.

[0089] Each of the wedge-shaped members 2 and 3 can move along the inner side of the conical nest N toward the narrow end E1 and return toward the wide end E2.

[0090] The rope anchor A further includes one or more spring members 4, which are used to actuate and / or are arranged to actuate one or more wedge members 2, 3 toward the narrow end E1 of the conical nest N. Thus, the rope anchor A can itself promote wedging and prevent wedging release, which in particular promotes the strength and reliability of the anchoring, and thus also promotes safety.

[0091] The rope anchor A further includes a release mechanism M, which is actuated to move one or more wedge-shaped members 2, 3 toward the wide end E2 of the conical nest N. This is particularly advantageous because it allows for quick and easy operation of the rope anchor A so that the rope R can pass through it. This is advantageous when the elevator is a construction-phase elevator, such as, in particular, so-called skip elevators, where additional portions of the rope R need to be fed into the elevator rope system. This provides a feasible wedge-type rope anchor A for this type of elevator.

[0092] exist Figures 1-8 In a preferred embodiment, the cross-section of each of the R is circular. Therefore, in the illustrated preferred embodiment, the rope anchor A is suitable for anchoring one or more ropes R with circular cross-sections. This facilitates providing a wedge-type rope anchor A for construction-phase elevators in which the(multiple) ropes(R) to be anchored have circular cross-sections. Thus, inexpensive and durable conventional types of rope can be readily used in construction-phase environments where these properties are valuable for safety.

[0093] exist Figures 1-8 In a preferred embodiment, the release mechanism M includes a rotatable actuating member 10, which is rotatable to move one or more wedge-shaped members 2, 3 toward the wide end E2 of the conical nest N. Figure 1 As shown, the rotatable actuating member 10 preferably comprises a hexagonal head. Therefore, for example, it can be easily turned by a bolt wrench.

[0094] Preferred details of the release mechanism M are as follows Figure 2 and Figure 3 As can be seen in the text. Figure 2 The diagram shows the rope anchor A and the rope R when the rope anchor A is in the anchored state, and... Figure 2 The diagram shows the rope anchor A in the released state, where the release mechanism M has been actuated.

[0095] The release mechanism M includes a push member 20 movable to push the wedge-shaped members 2 and 3 installed in the conical nest N toward the wide end E2, and a rotatable actuating member 10 connected to the push member 20 in a force transmission manner; wherein the push member 20 is movable [to push the wedge-shaped members 2 and 3 installed in the conical nest N toward the wide end E2] by rotating the rotatable actuating member 10.

[0096] The rope anchor A, preferably in particular the rotatable actuating member 10, includes a cam head 11, which can be rotated by actuation of the actuating member 10 to force the pushing member 20 to move to push the wedge members 2, 3 mounted in the conical nest N toward the wide end E2.

[0097] The cam head 11 can be rotated by actuation of the actuating member 10 to press against the mating member 12, thereby forcing the actuating member 10 to move relative to the mating member 12. The movement of the actuating member 10 relative to the mating member 12 is arranged to move the pushing member 20 to push the wedge members 2, 3 mounted in the conical nest N toward the wide end E2.

[0098] exist Figures 1-8 In a preferred embodiment, the rope anchor A includes a frame F, and the mating member 12 is immovable relative to the frame F, while the actuating member 10 is rotatable and movable in its radial direction relative to the frame F. The release mechanism M includes transmission members 13 and 14 located between the movable actuating member 10 and the pushing member 20, for transmitting the radial movement of the movable actuating member 10 to the pushing member 20 to move it and push the wedge members 2 and 3. For example, in... Figure 7 In this configuration, transmission members 13 and 14 are visible. In this case, transmission members 13 and 14 include a support plate 14 carrying the push member 20, and an elongated rod 13 arranged to transmit radial movement of the actuating member 10 to the support plate 14. The elongated rod 13 extends from a first side of the wedge-shaped housing 1 to a second side of the wedge-shaped housing 1, and specifically through it. Thus, as shown, the actuating member 10 and the push member 20 can be located on opposite sides of the wedge-shaped housing 1. This allows the actuating member 10 to be easily positioned on one side of the housing 1 [the upper side in the figure], with the wide end E2 of the nested N open towards that side; while the push member is positioned on one side of the housing 1 [the lower side in the figure], with the narrow end E1 of the nested N open towards that side. Therefore, even if the actuating member 10 is elsewhere, push can be achieved from one side of the housing 1 [the lower side in the figure], with the narrow end E1 of the nested N open towards that side. This facilitates easy access to and positioning of the actuating member 10 relative to the (plural) ropes R.

[0099] In order to enable the movable actuating member 10 to move radially, its movement is preferably guided by a guiding member, which preferably includes a guide hole 15 formed in the wedge-shaped housing 1 and the elongated rod 13, and the elongated rod 13 extends through the guide hole 15 and the guide hole 15 is arranged to guide the elongated rod 13 to move only in the radial direction of the actuating member 10.

[0100] The pushing member 20 is preferably a loop around the rope R, which can move around the rope R to press against the wedge members 2 and 3.

[0101] The operation of the release mechanism M is based on Figures 1-8 It becomes obvious. That is, when actuated by rotation, for example using a wrench W, the actuating member 10 rotates so that the cam head 11 rotates to press against the mating member 12. This pressing force causes the actuating member 10 to […] in its radial direction. Figure 2 and Figure 3 The radial movement is relative to the mating member 12. This radial movement is transmitted to the pushing member 20 by transmission members 13, 14 provided between the movable actuating member 10 and the pushing member 20, causing it to be moved [in the center upward]. Figure 2 and 3 [Upward] to push the wedge-shaped components 2 and 3.

[0102] Figure 9 Further details of the preferred configuration of the wedge-shaped members 2 and 3 and their surrounding structure are shown. For example... Figure 9 As shown, preferably, each of the wedge-shaped members 2, 3 includes a rope groove 7 for receiving a rope R. The rope groove 7 preferably includes two arcuate sides for supporting opposing arcuate sides of the rope R, and its cross-section is circular. The rope groove 7 is preferably an undercut rope groove. Therefore, the rope groove includes a bottom recess 7a. The recess forms a space in which the rope R disposed in the rope groove 7 will not penetrate to the bottom of the rope groove 7.

[0103] The rope anchor A preferably includes a sliding bearing 9, which is disposed between the wall of the wedge-shaped housing 1 and each of the wedge-shaped members 2, 3, as shown below. Figure 9 and Figure 10 As shown in the diagram. Preferably, the sliding bearing 9 is made of a different material than the wall 8 of the wedge-shaped housing 1 and each of the wedge-shaped members 2, 3. Preferably, the sliding bearing 9 comprises a plastic, such as PTFE. Preferably, the wedge-shaped housing 1 and each of the wedge-shaped members 2, 3 comprise a metal. Preferably, the sliding bearing 9 is non-metallic. Preferably, the sliding bearing 9 is a strip-shaped member. Preferably, the strip-shaped member 9 has a thickness of less than 5 mm, a length of more than 5 cm, and a width of more than 1 cm.

[0104] like Figure 11As schematically shown, the rope anchor A preferably, but not necessarily, includes a releasable rope locking member 16 mounted on the frame F for locking one or more ropes R that are immovable relative to the frame F, including at least the ropes R. The locking member 16 is arranged to act on the portion of the rope R to be locked, which extends from one side of the housing 1 [upper side in the figure] into the nest N, the wide end E2 of the nest N being open towards that side. This rope portion is not tensioned by a movable load of the elevator, wherein the load is the elevator or a counterweight. However, this rope portion may be tensioned by the weight of the rope, which could pull the rope, thereby harmfully counteracting the wedging effect and / or making it difficult to control the rope balance and movement in certain situations after the wedging is released. The releasable rope locking member 16 facilitates control of rope tension during release by the release mechanism M. For example, the rope tension can thus be at least partially transferred from being carried by the wedges 2, 3 and the nest N to being carried by the locking member 16. After release, the release of the locking member 16 can be performed. Therefore, wedges 2 and 3 and nest N can be used as primary components for anchoring (multiple) ropes R, while locking component 16 serves as an auxiliary component to assist in the release phase and / or to eliminate unwanted tension on the rope portion tensioned by the rope weight. The rope locking component 16 preferably comprises two compression members 16a, 16b located on opposite sides of each rope R to be locked, preferably movable toward each other by a screw-on fastening component 17, such as a screw-on fastening component including bolts and nuts. Preferred details of the fastening component 17 are already provided. Figure 12 , Figures 16-18 It is shown in the middle.

[0105] like Figure 11 As schematically shown, the rope anchor A preferably, but not necessarily, includes one or more guide rollers for guiding the rope R, particularly from one side of the housing 1 [the upper side in the figure], to the wide end E2 of the conical nest N, which is open towards that side. The one or more guide rollers include a guide roller 110 for acting on a portion of the rope R, extending from one side of the housing 1 (the upper side in the figure) into the nest N, with the wide end E2 of the nest N open towards that side. When the rope anchor A is positioned such that the narrow end E2 is lower than the wide end E1, the guide roller 110 is higher than the conical nest N. Guiding the rope R into the wide end E2 of the conical nest N facilitates control of the movement and path of the rope R as it passes through the nest N, particularly when additional portions of the rope R are supplied from the rope supply reservoir via the released anchors A, A'. Thus, the rope R can move smoothly and does not rub against portions of the anchors A, A' during the supply. The guide roller 110 is preferably freely rotatable.

[0106] Figure 12 , Figure 16 and Figure 17 A second embodiment of the rope anchor is shown, wherein the rope anchor A' is based on Figure 11 Anchor A' is schematically shown when the anchor includes the locking member 16 and the guide roller 110. Figure 12 , Figure 16 and Figure 17 In this context, the anchor is referred to as A', and the frame is referred to as F'. The frame is in... Figure 12 , Figure 16 and Figure 17 Anchor A' has a special shape, as indicated by reference numeral F', so that it can support locking component 16 and guide roller 110. The other parts of anchor A' are as described above, and as... Figures 1-11 As shown in the diagram. However, the number of ropes differs from the number of ropes in the first embodiment.

[0107] Figures 13-15 The elevator device 100 is in different stages of a method according to one embodiment.

[0108] exist Figure 13 In the elevator assembly 100, the assembly 100 includes an elevator car 102 in a shaft 103, a rope 101 including a rope R connected to the elevator car 102, and a rope anchor A; A' for anchoring the rope R, as shown in reference. Figures 1-12 , Figures 16-18 As described in any of the diagrams. Rope anchor A; A' is already present. Figures 13-15 The elevator assembly 100 is schematically shown. The elevator assembly 100 includes a rope supply reservoir 104, from which a rope R passes through rope anchors A and A', and from there through to the elevator car 102. The rope R bypasses the drive wheel 106 of a hoisting machine 105 movably mounted in a first position I in the shaft. The rope R enters from the rope supply reservoir 104 into the wide end E2 of a conical nest N, passes through the conical nest N, exits from the narrow end E1 of the conical nest N, and reaches the elevator car 102.

[0109] exist Figure 13 In the elevator device 100, rope anchors A and A' are in an anchored state (i.e., not in a released state), for example, Figure 2 and Figure 12 As shown in the diagram. When the hoist 105 is in the first position I, the elevator car is used to transport passengers and / or goods. The elevator assembly 100 includes a hoisting device 107 for raising the hoist 105 to a second position II in the shaft, which is higher than the first position I, and / or raising the anchors A, A' even higher in the shaft 103. When the rope anchors A, A' are in the anchored state, each of one or more wedge members 2, 3 is wedged against the rope R passing through the conical nest N, for example, as shown in the diagram. Figure 2 As shown in the image.

[0110] exist Figure 13 In the device 100, rope anchors A and A' are positioned such that the narrow end E2 is lower than the wide end E1. A rope supply reservoir 104 is lower than rope anchors A and A', and rope R passes upward from the rope supply reservoir 104, over a guide roller 110 mounted above the conical nest N, and downward to rope anchors A and A'. Preferred features and advantages of the guide roller 110 have been described above. Preferably, the rope supply reservoir 104 is at least 10 meters lower than rope anchors A and A', whereby the advantages of the guide roller 110 are most significant. Rope R preferably passes through the releasable rope locking member 16, which can be locked or unlocked. The rope supply reservoir 104 preferably includes one or more rope reels. For example, the one or more rope reels can be installed on a platform or in a pit in a shaft.

[0111] In a method for constructing an elevator according to one embodiment, the method includes providing a reference. Figure 13 Elevator device 100 shown and described.

[0112] The method includes using the elevator car 102 to transport passengers and / or goods while the hoist 105 is in the first position I (first use); and performing construction work while the hoist 105 is in the first position I; and subsequently releasing anchors A and A', the release including an actuation release mechanism M to move one or more wedge members 2, 3 toward the wide end E2 of the conical nest N; and subsequently raising the hoist 105 and installing it in a second position II above the first position I, the method including supplying additional portions of rope R from the rope supply memory 104 via the released anchors A and A' during the raising, preferably by means of the tension caused by the raising; and subsequently (i.e. after the raising) re-anchoring the rope R with anchors A and A'. Re-anchoring preferably includes actuating the release mechanism M, particularly in a reverse manner, to allow one or more springs to move one or more wedge members 2, 3 toward the narrow end E1 of the conical nest N. After the re-anchoring, the method includes using the elevator car 102 to transport passengers and / or goods while the hoist 105 is in the second position II (second use).

[0113] The lifting process preferably also includes lifting anchor A; A' and installing it to a higher position than before and / or rope fastener 18 of lifting rope R and installing it to a higher position than before.

[0114] To facilitate the lifting steps of the method, the method preferably includes suspending the hoist 105, rope anchors A, A', and rope fasteners 18 on the lifting device 107. These can be lifted individually or simultaneously, for example, by a support structure (not shown) suspended on the lifting device 107. In the latter case, the support structure can be a vertically movable lifting platform in the shaft, such as a vertically movable work platform.

[0115] When the device / rope anchor A' includes a releasable rope locking component 16, the anchor A is released; A' also includes the release of the releasable rope locking component 16.

[0116] Figure 18 It shows Figure 12 A cross-section of the rope anchor A' shows further details of the preferred releasable rope locking component 16. Figure 18 In this configuration, the rope locking component 16 includes two compression members 16a, 16b on opposite sides of each rope R to be locked, which are preferentially movable toward each other via a screw-on fastening member 17. Figure 18 In one embodiment, the screw-on fastening member 17 comprises a plurality of bolts 19 extending through the two compression members 16a, 16b and nuts 20 fastened to the bolts 19. The screw-on fastening member 17 further includes disc springs 21 stacked between each nut 20 and the compression member 16b to be elastically compressed when the screw-on fastening member 17 is tightened. This facilitates achieving and maintaining a relatively constant tightening force. The rope locking member 16 further includes a spring 22 located between the two compression members 16a, 16b, which elastically resists movement of the two compression members 16a, 16b toward each other. This provides that when the lock is released by loosening the screw-on fastening member 17, the spring force drives the two compression members 16a, 16b on opposite sides of each rope R away from each other. Spring 22 ensures that when the locking member is released, a gap is formed between the rope R and the two compression members 16a, 16b, and the rope R can be guided freely through the locking member 16 without being damaged by friction.

[0117] exist Figure 18 In this configuration, each of the two compression members 16a, 16b on opposite sides of each rope R to be locked includes a rope groove 23 for receiving the rope R, which is compressed in the groove 23 when the releasable rope locking member 16 is engaged.

[0118] Typically, the rope anchor A comprises two wedge-shaped members 2 and 3, with a compression gap G passing between them, through which the rope R can be positioned. However, this solution can also be achieved using only one wedge member in the nest. In this case, the compression gap will be formed between the bottom wedge member and the inner surface of the tapered nest.

[0119] Generally, preferably, the rope R is a lifting rope. Generally, the lifting mechanism 105 preferably includes a drive wheel 106 for driving the lifting rope and a motor for rotating the drive wheel 106.

[0120] Generally, in addition to or as an alternative to the locking member 16, the guide roller 110 can be locked so that it is non-rotatable relative to the frames F, F', thereby at least partially eliminating the tension transmission to the wedge. However, this is not necessary.

[0121] Generally, multiple ropes R are shown in the attached drawings because elevator ropes typically involve more than one rope. In the attached drawings, each rope R is anchored as described.

It will be apparent to those skilled in the art that the inventive concept can be implemented in various ways. Therefore, those skilled in the art will understand from the above teachings that the above embodiments of the invention can be modified or altered without departing from the invention. Therefore, it should be understood that the invention and its embodiments are not limited to the above examples, but can be varied within the scope of the claims.
