Description

Technical Field

[0001] The invention relates to the installation of elevator ropes, wherein an elevator is in particular an elevator for transporting passengers and / or freight. Background Art

[0002] Conventional elevators have multiple ropes connected to the elevator car and counterweight.The ropes usually pass over a traction sheave and suspend the elevator car and counterweight on opposite sides of the traction sheave.

[0003] When a new elevator is built, or when the old rope of an existing elevator needs to be replaced, a new rope is installed. The rope is usually stored on a rope reel and brought to the site.

[0004] Traditional elevator ropes are made of steel wire, and they are relatively thick, stiff, and heavy. Consequently, the rope reels are also large and heavy. During rope installation, the rope reels are typically located at a landing or in the pit. They are unwound from this location and fed into the hoist system by pulling. Heavy ropes require robust equipment to handle them.

[0005] Documents EP3048076A1, EP3533745A1, EP2470463A1 and EP2016015A1 disclose rope installation methods, wherein a rope reel is positioned at a landing or in the pit of an elevator.

[0006] Elevators are also known that have relatively thin, lightweight ropes that may be coated with non-metallic materials. For example, EP1517850A1 discloses such an elevator. These ropes are relatively flexible and lightweight. The ropes of such elevators can be installed much like conventional ropes. However, coated ropes require careful handling to prevent damage to the sensitive coating. Furthermore, the ropes are lightweight, easy to move, and can be used in large numbers. Due to their thinness, care must be taken to ensure they are well controlled.

[0007] One disadvantage of known elevator solutions is that it is challenging to install the elevator ropes simply, quickly and in a well-controlled manner. Summary of the Invention

[0008] The object of the present invention is to introduce an improved method for installing elevator ropes, as well as an improved device and apparatus for installing elevator ropes.

[0009] An object is to introduce a new solution by which one or more of the above-mentioned problems of the prior art and / or the disadvantages discussed or hinted at elsewhere in the specification can be alleviated. An object is in particular to introduce a solution that facilitates handling and control of elevator ropes.

[0010] In particular, a solution is introduced which provides good control of the course of the rope to and / or from the edge of the rope wheel around which the rope is to be moved in the method.

[0011] In particular a solution is introduced which provides good control of the rope's arrival and / or departure from an array of rope wheels around which the rope is to be moved.

[0012] In particular, a solution is introduced which facilitates performing the installation steps quickly and simply and using simple tools.

[0013] In particular, solutions are introduced which facilitate the gentle and efficient installation of ropes with sensitive surface structures and / or thin ropes.

[0014] A new method for installing elevator ropes is proposed, the method comprising: arranging (A1) a plurality of ropes to pass from one or more rope reels mounted on the elevator car to a rope wheel mounted separately from the car, passing around the rope wheel, and from the rope wheel to a clamping device mounted on the car; then moving the elevator car vertically relative to the rope wheel while each rope is clamped by the clamping device, in particular thereby pulling the ropes from the one or more rope reels using the clamping device that moves with the car.

[0015] With this solution, one or more of the above-mentioned objectives may be facilitated.

[0016] Preferred further details of the method are described below, which can be combined with the arrangement alone or in any combination.

[0017] In a preferred embodiment, in the arrangement (A1), the ropes are arranged to pass from one or more rope reels mounted on the elevator car via rope guides mounted on the car to a rope pulley; and / or from the rope pulley via rope guides mounted on the car to a clamping device mounted on the car.

[0018] In a preferred embodiment, the method comprises guiding the movement of the ropes during said moving the elevator car by means of a rope guide mounted on the car and / or by means of spaced-apart guide openings of the rope guides, in particular.

[0019] In a preferred embodiment, the arrangement comprises mounting the clamping device on the car, preferably by fixing it to a railing of the car.

[0020] In a preferred embodiment, said arrangement (A1 ) comprises clamping the end section of each rope with a clamping device.

[0021] In a preferred embodiment, the arrangement (A1) comprises clamping the end section of each rope with a clamping device, and the clamping device comprises a clamp body, the clamp body comprising a plurality of openings extending through the clamp body in a first direction, and the clamping of each rope comprises bending a loop from the end section of the rope and inserting the loop through the opening of the clamp body from a first side (s1) of the clamp body, and inserting a locking member through the loop eyelet of the loop on a second side (s2) of the clamp body to prevent the loop from returning to the first side (s1) by the locking member. Preferably, although not necessarily, a common locking member is inserted through the loop eyelets of more than one, preferably all, of the ropes. The common locking member is preferably an elongated locking rod, preferably made of plastic.

[0022] In a preferred embodiment, the method, in particular the arrangement (A1), involves positioning only one rope in each guide opening of the rope guide. This allows for individual control of each rope without generating excessive contact forces between the guide and the individual rope. The rope array can also be well controlled. This positioning is then preferably accomplished by means of the side grooves of the openings, in particular by moving the ropes transversely to the ropes via the side grooves.

[0023] In a preferred embodiment, said vertically moving the elevator car is moving the elevator car downwards [i.e., said movement is lowering the elevator car]. The car is arranged to exert a tension on the end section of each rope using a clamping device as it descends. The tension is arranged to pull (unwind) the rope from one or more rope reels.

[0024] In a preferred embodiment, the method comprises [particularly before said arrangement A1] making preparations including providing one or more rope reels storing a plurality of ropes, mounting said one or more rope reels on the elevator car, and moving the elevator car upwards to a position close to a rope pulley mounted separately from the car using a temporary hoist.

[0025] In a preferred embodiment, the method further comprises placing ropes on one side of a rope pulley mounted separately from the car to suspend the elevator car, and on the other (opposite) side of the pulley to suspend the counterweight. Thus, this method can be used to construct a counterweight elevator. In this method, these steps follow the process of vertically moving the elevator car relative to the rope pulley. These steps are facilitated by the earlier steps and how the components of this arrangement are arranged. These steps can be further facilitated by the advantageous design and implementation of guides and / or clamps.

[0026] In a preferred embodiment, the method or arrangement includes a rope pulley mounted on the underside of the car compartment, below the point where the clamping device is mounted on the car and extending completely or at least substantially horizontally. The rope 1 can be easily routed around the rope pulley without lateral displacement. Thus, the method can be effectively continued to provide suspension for the car via the rope pulley.

[0027] In a preferred embodiment, the method comprises, after moving the elevator car downwards, for example after reaching the pit:

[0028] dismantling the gripping device and moving it to pull the rope 1 around one or more rope wheels mounted on the underside of the car cabin, which preferably includes pulling the gripping device with the traction cable; and thereafter

[0029] reinstalling the clamping device on the car; and thereafter

[0030] arranging the ropes on the rope reel side of the rope pulley to pass over one or more rope pulleys mounted on the counterweight and from said rope pulleys to a clamping device mounted on the car, the arranging comprising removing an end segment of each rope from the rope reel and clamping it with a clamping device, mounting the clamping device on the car by securing the clamping device to a railing of the car; and thereafter

[0031] moving the elevator car upward [i.e., raising the elevator car]; and thereafter

[0032] The end section of the rope is fixed to a rope terminal which is preferably mounted in the upper end t of the hoistway.

[0033] In a preferred embodiment of the arrangement or method, said vertically moving the elevator car is performed using a hoist. The hoist is preferably in particular a temporary hoist, and in this case the method preferably comprises removing the ropes after installation.

[0034] A new arrangement for installing elevator ropes is also proposed, which comprises:

[0035] a plurality of ropes arranged to pass from one or more rope reels mounted on the elevator car to a rope pulley mounted separately from the car, pass around the rope pulley, and pass from the rope pulley to a gripping device mounted on the car; and

[0036] A hoist is operable to move the elevator car vertically relative to the rope pulley, such as in particular to lift or lower it, while each rope is gripped by a gripping device, in particular thereby pulling the ropes from one or more rope reels with the gripping device moving with the car.

[0037] With this solution, one or more of the above-mentioned objectives may be facilitated.

[0038] Preferred further details of the device and the method are described below, which can be combined with the arrangement and the method individually or in any combination.

[0039] In a preferred embodiment of the arrangement or method, the rope is arranged to:

[0040] from one or more rope reels mounted on the elevator car via rope guides mounted on the car to a rope pulley; and / or

[0041] From the rope pulley, a rope guide is provided on the car, leading to a clamping device on the car.

[0042] In a preferred embodiment of the arrangement or method, the clamping device comprises a clamp body including a plurality of openings extending through the clamp body in a first direction, and loops bent from the end segments of each cord are inserted through the openings of the clamp body from a first side (s1) of the clamp body, and locking members are inserted through the loop eyelets of the loops on a second side (s2) of the clamp body, the return of the loops to the first side (s1) being blocked by the locking members. The locking members are preferably inserted through the loop eyelets of the loops in a second direction D2 orthogonal to the first direction D1.

[0043] In a preferred embodiment of the arrangement or method, each of said openings of the clamp body is elongated in a direction (D3) orthogonal to the first direction (D1), and each loop of rope is inserted through one of said elongated openings. Said direction (D3) is also orthogonal to the second direction (D2).

[0044] In a preferred embodiment of the arrangement or method, each of said rope guides (6, 7) comprises a plurality of spaced apart guide openings parallel to one another for receiving a rope, the rope being arranged to pass through different guide openings.

[0045] In a preferred embodiment of the arrangement or method, only one rope is positioned in each of the guide openings of the rope guide. This allows for individual control of each rope without generating excessive contact forces between the guide and the individual ropes. This also allows for good control of the rope array.

[0046] In a preferred embodiment of the arrangement or method, the rim of the rope pulley, or at least the portion of the rim where the rope contacts the rim, is located beside the vertical projection of the cabin box, and the rope guide [6] is mounted on the car so that the guide opening of the rope guide is located outside the vertical projection of the cabin box. This facilitates good control of the route of the rope without contact with other components that could damage the surface of the rope when it is moved from the rope reel to its intended position. This also facilitates good control of the array in which the rope passes.

[0047] In a preferred embodiment of the arrangement or method, the guide opening of the guide element [6] is arranged to guide the rope passing through one or more rope reels, in particular to divert the route of the rope so that the rope extends from the guide element [6] as a row and / or next to the vertical projection of the cabin box to the edge of the rope wheel.

[0048] In a preferred embodiment of the arrangement or method, the edge of the rope pulley, or at least the portion of the edge where the rope leaves the edge towards the guide [7], is beside the vertical projection of the cabin box, and the rope guide [7] is mounted on the car so that the guide opening of the rope guide is outside the vertical projection of the cabin box. This helps to ensure good control of the rope route without it coming into contact with other components that could damage the surface of the rope when it is moved from the rope reel to its intended position. This also helps to ensure good control of the array in which the rope passes.

[0049] In a preferred embodiment of the arrangement or method, the guide openings of the rope guide [7] are arranged to guide the ropes passing from the rope wheel so that they extend from the rope wheel to the guide openings of the guide [7] as a row and / or next to the vertical projection of the cabin box.

[0050] In a preferred embodiment of the arrangement or method, one or more rope reels are mounted on the roof of the car box in the vertical projection of the car box. A guide [6] facilitates the controlled passage of the rope from this location to another desired route, for example first laterally and then vertically towards the rope wheel.

[0051] In a preferred embodiment of the arrangement or method the guide opening is offset in the direction of the rotation axis (x) of the rope wheel and is in particular arranged to guide the ropes to form a rope row, wherein the ropes are offset in the direction of the rotation axis (x) of the rope wheel.

[0052] In a preferred embodiment of the arrangement or method, the rope guide [6] is fixed to the car, preferably to the car railing, above the level of the rope reel or reels, and / or the rope guide [7] is fixed to the car, preferably to the car railing, above the level of the clamping device.

[0053] In a preferred embodiment of the arrangement or method, the clamping device is fixed to a component of the car, preferably to a handrail of the car, preferably with a strap.

[0054] In a preferred embodiment of the arrangement or method, the rope pulley is in a freely rotatable state during said moving the elevator car.

[0055] In a preferred embodiment of the arrangement or method, the rope sheave is a drive sheave of a hoist, the hoist comprising a motor for rotating the rope sheave.

[0056] In a preferred embodiment of the arrangement or method, each of said ropes is

[0057] Coated rope, in particular comprising one or more load-bearing members coated with a surface material which is non-metallic and / or comprises a polymer, and / or

[0058] Ropes with a diameter less than 10 mm.

[0059] In a preferred embodiment of the arrangement or method, each guide opening of the rope guide extends through the rope guide in a first direction (d1), and each guide opening has a side groove that is open or at least openable in a second direction (d2) orthogonal to the first direction (d1). Thus, in the method, the rope can be moved or at least moved into and out of the guide opening via the side groove in a transverse direction of the rope. Preferably, each guide opening is elongated in the second direction d2 orthogonal to the first direction d1.

[0060] In a preferred embodiment of the arrangement or method, the guide preferably comprises one or more latching members positionable to close the slot and displaceable to open the slot.

[0061] In a preferred embodiment of the arrangement or method, the guide is fork-shaped.

[0062] In a preferred embodiment of the arrangement or method, the guide is made of plastic.

[0063] Typically, the car preferably includes an interior in which passengers and / or cargo can be transported. The car preferably also includes one or more doors through which the interior can be opened and closed. The doors are preferably automatic doors, whereby the elevator solution can provide comfortable and safe elevator use. BRIEF DESCRIPTION OF THE DRAWINGS

[0076] Figure 21 A preferred structure of a rope according to an embodiment is shown. DETAILED DESCRIPTION

[0077] Figure 1The method according to an embodiment is shown in a stage. In this stage, preparations are made for the installation of the ropes. In this stage, the method comprises providing one or more rope reels 2 storing a plurality of ropes 1, mounting said one or more rope reels 2 on the elevator car 3, and moving the elevator car 3 upwards with a temporary hoist 11 to a position close to a rope pulley 4 mounted separately from the car 3. In the case shown, said position is at the upper end of the elevator shaft H. The rope pulley 4 is preferably a drive pulley of a hoist comprising a motor 10 for rotating the rope pulley 4, such as Figure 1 The rope wheel 4 is preferably installed in the upper end t of the hoistway H.

[0078] Figure 2 Another stage of the method according to an embodiment is shown. In this stage, the method comprises arranging [A1] a plurality of ropes 1 to pass from one or more rope reels 2 mounted on the elevator car 3 to a rope wheel 4 mounted separately from the car 3, around the rope wheel 4, and from the rope wheel 4 to a clamping device 5 mounted on the car 3. In the arrangement, the ropes 1 are arranged to pass from one or more rope reels 2 mounted on the elevator car 3 to the rope wheel 4 via a rope guide 6 mounted on the car 3, and from the rope wheel 4 to the clamping device 5 mounted on the car 3 via a rope guide 7 mounted on the car. By these steps, a structure as shown in FIG. Figure 3 An elevator roping arrangement 100 is shown.

[0079] Figure 4 A further stage after arrangement [A1] is shown. In this stage, the method comprises vertically moving the elevator car 3 relative to the rope pulley 4 while each rope 1 is gripped by a gripping device 5, in particular thereby pulling the rope 1 from one or more rope reels 2 using the gripping device 5 that moves with the car 3. Figure 4 As shown, the vertically moving elevator car 3 is performed using a temporary hoist 11 , more specifically, by lowering the elevator car 3 with the temporary hoist 11 . Figure 4 The arrows in FIG. 1 illustrate the movement of the various parts of the arrangement 100 during the vertical movement. In this embodiment, the temporary hoist 11 is arranged to be supported from above the elevator car 3. During the movement of the elevator car 3, the rope pulley 4 is preferably in a freely rotatable state. Therefore, it does not brake the movement of the ropes 1, and they can be smoothly pulled out from the one or more rope reels 2. When the rope pulley 4 is the drive pulley of a hoist including a motor 10 for rotating the rope pulley 4, in order to achieve this free rotation, preferably, no brake is in a braking state during the movement of the elevator car 3, and the motor 10 is not energized to electrically generate a torque on the pulley for braking the rotation during the movement of the elevator car 3.

[0080] The method consists in guiding the movement of the rope vertically during said movement, through the guides 6 , 7 , in particular through the opening 8 thereof.

[0081] exist Figure 4 In the present invention, the vertical movement of the elevator car 3 is to lower the elevator in the hoistway. When the car 3 is lowered, it is arranged to exert a tension on the end 1a of each rope 1 using a clamping device 5. The tension is arranged to pull (unwind) the rope from one or more rope reels 2.

[0082] In this method, the rope 1 is arranged to pass from one or more rope reels 2 through a rope guide 6 mounted on the car 3 so that the rope 1 can be guided to the correct position (horizontally) on the horizontal plane of the car 3. Therefore, regardless of the horizontal position of the rope reels 2, the rope can be extended to the rope pulley 4 via the position of the rope guide 6. Therefore, when the car 3 moves vertically to pull the rope 1 from the one or more rope reels 2 (where the gripping device 5 moves with the car 3), the rope reaches the edge of the rope pulley 4 from the position of the rope guide 6, which facilitates good control of the rope's route without contacting other components that could damage the surface of the rope 1 as it moves from the rope reel 2 to its intended position. The position of the rope guide 6 (horizontally) is preferably such that the rope 1 passes from the rope guide 6 to the edge of the rope pulley 4 in a vertical, or at least substantially vertical, direction. Therefore, vertical movement of the car 3 does not significantly change the angle at which the rope 1 reaches the edge of the rope pulley 4. The position of the rope guide 6 can be chosen relatively freely to coordinate well with the position of the rope sheave 4, for example even outside the projection of the car cabin 3a, as will be explained later. The rope guide 6 is preferably arranged so that its guiding ropes 1 extend from the guide 6 toward the edge of the rope sheave 4 in a desired array, preferably in a row. This helps to better control the route of the individual ropes and the array in which they reach the edge of the rope sheave 4. This is advantageous because it helps the ropes 1 reaching the rope sheave to be placed in the correct position, for example in the groove of the rope sheave. This is particularly advantageous when the car 1 is positioned close to the rope sheave 4. The preferred details of the structure of the rope guide 6 are described elsewhere in this application.

[0083] In this method, the rope 1 is arranged to pass from the rope sheave 4 to the clamping device 5 mounted on the car 3 via a rope guide 7 mounted on the car 3, so that the rope 1 can be guided horizontally to the correct position on the horizontal plane of the car 3. Thus, the rope can be extended from the rope sheave 4 to the clamping device 5 via the position of the rope guide 7. Therefore, when the car 3 moves vertically to pull the rope 1 from one or more rope reels 2 while the clamping device 5 moves with the car 3, the rope extends from the edge of the rope sheave 4 to the position of the rope guide 7, which helps to effectively control the rope route without contacting other components (other components may damage the surface of the rope 1 when the rope 1 moves from the rope reel 2 to its intended position). The position of the rope guide 7 (horizontally) is preferably such that the rope 1 passes vertically, or at least substantially vertically, from the edge of the rope sheave 4 to the rope guide 7. Therefore, vertical movement of the car 3 does not cause a significant change in the angle at which the rope 1 leaves the edge of the rope sheave 4. The position of the rope guide 7 can be chosen relatively freely to best suit the position of the rope sheave 4, for example even outside the projection of the car cabin 3a. The rope guide 7 is preferably designed so that it guides the ropes 1 from the rope sheave 4 to the guide 7 in a desired array (preferably in a row). This helps to effectively control the route of the individual ropes and the array in which they exit the edge of the rope sheave 4. This is advantageous because it helps the ropes 1 leaving the rope sheave remain in the correct position, for example, in the groove of the rope sheave, and not tend to move laterally out of this position. The preferred details of the structure of the rope guide 7 are described elsewhere in this application.

[0084] Said plurality of ropes 1 may typically comprise two or more ropes, however most preferably more ropes. In the example shown, three ropes 1 have been shown, however there may be more than three ropes.

[0085] Figure 5 FIG. 2 shows another stage after the step of vertically moving the elevator car 3 by lowering the elevator car 3 in the hoistway H. The elevator car 3 has been lowered as shown in FIG. Figure 4 As shown, it is lowered until it has reached the bottom pit p of the shaft.

[0086] The method also includes placing ropes 1 on one side of the rope sheave 4 to suspend the elevator car 1, and placing ropes 1 on the other [opposite] side thereof to suspend the counterweight 14. Thus, a counterweight elevator can be constructed using this method. These steps are described below.

[0087] After the car 1 reaches the pit, the method comprises disassembling the gripping device 5 and moving it to pull the rope 1 around one or more rope wheels 12 mounted on the bottom side of the car cabin 3a, which preferably comprises pulling the gripping device 5 with the traction cable 13. Thus, the gripping device 5 can be used to handle all ropes 1 together and also to apply a simultaneous tension in all ropes at this stage, whereby they can be simply and efficiently arranged around one or more rope wheels 12. This pulling of the gripping device 5 also causes the rope 1 to be unwound by an additional length from the one or more rope reels 2, as Figure 7 These steps are shown in the arrows in Figure 6 and Figure 7 . During this pulling, the rope guides 6 and 7 can be used to guide the rope 1 during said pulling. After the pulling, the method comprises reinstalling the clamping device 5 on the car 3. In a preferred embodiment, this is performed by fixing the clamping device 5 to a position on the handrail of the car 3, which is above the rope pulley 12 around which the rope 1 is pulled during said pulling (the last of one or more rope pulleys 12 in the sequence of rope movements that occur during said pulling). As a result, the rope 1 rises essentially vertically from the rope pulley 12 to the clamping device 5. Figure 8 The clamping device 5 is shown reinstalled on the car 3, and the subsequent steps in which the car 3 is moved using the temporary hoist 11 [in Figure 8 [Lifting in the middle] to a position close to the counterweight 14 installed in the hoistway H. Figure 9 The car 3 is shown positioned in this way. If the car 3 is already close to the counterweight 14 after descending into the pit p, this moving step may not be necessary.

[0088] The method includes, after reinstalling the gripping device 5 and moving (if any) to a position near the counterweight 14, the step of arranging [A2] the rope 1 on the rope reel 2 side of the rope pulley 4 so as to pass over one or more rope pulleys 14a mounted on the counterweight 14 and from the rope pulley 4 to a gripping device 15 mounted on the car 3. This arrangement [A2] includes removing the end 1b of each rope 1 from the rope reel 2, gripping it with a gripping device 15, and mounting the gripping device 15 on the car 3. In a preferred embodiment, this is performed by securing the gripping device 15 to the railing of the car 3, specifically at a position above the rope pulley 14a of the counterweight 14 around which the rope 1 is passed. Thus, the rope 1 rises substantially vertically from the rope pulley 14a to the gripping device 15. Consequently, subsequent vertical movement of the car 3 does not cause a significant change in the angle at which the rope 1 extends from the gripping device 15 to the edge of the rope pulley 14a, thereby ensuring good control of the rope during car movement. The gripping device 15 can, for example, be similar to the gripping device 5 described elsewhere. A rope guide 16 is preferably also mounted on the elevator car 3, via which the rope 1 is arranged to pass from the rope pulley 14a to the gripping device 15. The rope guide 16 is preferably configured to guide the rope 1 from the rope pulley 14a to the gripping device 15 in a row and / or alongside a vertical projection of the cabin box 3a. Thus, a controlled passage can be provided for the rope 1. The rope guide 16 can, for example, be similar to the rope guides 6, 7 described elsewhere.

[0089] After this arrangement (A2), the method comprises moving the elevator car 3 upwards (ie lifting the elevator car) using the temporary hoist 11. Figure 11 . At this stage, the two opposite end segments 1a, 1b of the rope 1 are clamped by the clamping device 5 mounted on the car 3. In particular, the end segment 1a of the portion of each rope extending on one side of the rope wheel 4 passes from the rope wheel 4 and around one or more rope wheels 12 mounted on the car, for example, on the bottom side of the car cabin 3a, and from there reaches the clamping device 5 mounted on the car 3. The end segment 1b of the portion of each rope extending on the other side (opposite to the aforementioned side) of the rope wheel 4 passes from the rope wheel 4 and around one or more rope wheels 14a mounted on the counterweight 14, and from there reaches the clamping device 15 mounted on the car 3. Figure 11 During the upward movement of the elevator car 3 as shown in FIG, the counterweight 14 is stationary in the hoistway H, for example resting on buffers supported in the hoistway H. This arrangement allows the rope end sections 1a, 1b to be brought to the upper end of the hoistway H, close to the position where they will be permanently fixed with the rope terminals, so as to form the final configuration. This arrangement also provides that the rope length will not need to be further adjusted very much, nor will there be a need to store additional rope length to enable the rope end sections 1a, 1b to be moved close to the position where they will be permanently fixed.

[0090] When the elevator car 3 is moved upward, the car 3 moves until it is at the upper end t of the hoistway H, as shown in FIG. Figure 12 Thereafter, the end sections 1a, 1b of the rope 1 are fixed to rope terminals 17a, 17b installed in the upper end t of the hoistway H, as shown. Figure 13 shown. Figure 13 Shown is the elevator roping completed and ready for use.

[0091] Figure 14-18 Shown Figure 3 Preferred details of the elevator roping arrangement 100 are provided, as well as details of the components used in the method and their preferred positioning.

[0092] like Figure 15 As shown, it is Figure 14 , each of the rope guides 6, 7 includes a plurality of spaced-apart guide openings 8 parallel to one another for receiving the ropes 1, which are arranged to pass through different guide openings 8. This helps the ropes pass as separate rows, regardless of the direction in which they are arranged to reach the guides 6, 7. There may be twists or angles at the points of the guides 6, 7, but due to the spaced-apart guide openings 8, the formation of the rows and the horizontal position of the rows at the level of the guides 6, 7 can be ensured.

[0093] like Figure 14 and 16 As shown, in this preferred embodiment, the guide opening 8 of the guide member 6 is arranged to guide the ropes 1 through one or more rope reels 2, in particular to deflect their course so that they extend as a row from the guide member 6 to the edge of the rope wheel 4 next to the vertical projection of the cabin box 3a. In this preferred embodiment, the rope wheel 4 installed separately from the car 3 is positioned so that the edge of the rope wheel 4, or more specifically at least the edge portion where the rope contacts the edge, is next to the vertical projection of the cabin box 3a, and the rope guide 6 is installed on the car 3 so that the guide opening 8 of the rope guide 6 is outside the vertical projection of the cabin box 3a. Therefore, the ropes 1 can extend from the guide member 6 next to the vertical projection of the cabin box 3a as a row in the vertical direction [i.e., in the upright direction] or at least in a substantially vertical direction to the edge of the rope wheel 4, as shown in FIG. Figure 16 In the embodiment shown, one or more rope reels 2 are mounted on top of the cabin box 3a of the car 3, within the vertical projection of the cabin box 3a. Guides 6 facilitate the controlled passage of the rope 1 from this location, first with at least some lateral displacement (diagonally in the figure), and then vertically to the rope pulley 4.

[0094] like Figure 14 and 17As shown, in this preferred embodiment, the guide opening 8 of the guide member 7 is arranged to guide the ropes 1 passing from the rope pulley 4 so that they extend as a row to the guide opening 8, particularly next to the vertical projection of the cabin box 3a. In this preferred embodiment, the rope pulley 4, which is mounted separately from the car 3, is positioned so that the edge of the rope pulley 4, or more specifically, at least the edge portion where the ropes exit the edge toward the guide member 7, is next to the vertical projection of the cabin box 3a, and the rope guide 7 is mounted on the car 3 so that the guide opening 8 of the rope guide 7 is outside the vertical projection of the cabin box 3a. Therefore, the ropes 1 can extend from the edge of the rope pulley 4 to the guide 7 as a row in a vertical direction (i.e., in an upright direction) or at least a substantially vertical direction next to the vertical projection of the cabin box 3a, as shown in FIG. Figure 17 shown.

[0095] In a preferred embodiment, the arrival and / or departure of the rope from the rope wheel array is facilitated by the guide openings 8 being offset in the direction of the rotation axis x of the rope wheel 4. Thus, the guide openings 8 are located on different vertical planes which are displaced in the direction of the rotation axis x when the axis x is horizontal. The guide openings 8 of each guide are particularly arranged to guide the rope 1 to form a rope row, wherein the rope 1 is offset in the direction of the rotation axis x of the rope wheel 4. This is for example Figure 16 and Figure 17 Thus, the rope 1 extends along different vertical planes which are displaced in the direction of the axis of rotation x when the axis x is horizontal. In each figure, the row thus formed is between the rope guides 6, 7 and the rope wheel 4.

[0096] It is generally preferred that, in this method and arrangement 100, the rope guide 6 be secured to the car 3, most preferably to the handrail 3b of the car 3, above the level of the one or more rope reels 2, as shown. The rope guide 7 be secured to the car 3, preferably to the handrail 3b of the car 3, above the level of the clamping device 5, as shown. Thus, the required deflection angle of the rope route from the guides 6, 7 is not excessive, thereby causing strong forces between the guides 6, 7 and the rope during the descent of the car 3. This results in a relatively smooth guidance without damaging the components. The guides 6, 7 can then be made of, for example, plastic. The method includes installing the rope guide 6 on the car 3 by securing it to the handrail 3b of the car 3, in particular by threading the rope upward from the one or more rope reels 2 to the rope guide 6, and / or installing the rope guide 7 on the car 3 by securing it to the handrail 3b of the car 3, in particular by threading the rope downward from the rope guide 7 to the clamping device 5.

[0097] In the following, reference Figure 14 and Figure 15The preferred structure of the guides 6, 7 is described in more detail.

[0098] The guides 6, 7 comprise fixing arms comprising fixing means, such as holes for fixing components, and guide openings 8, all at a distance from the fixing means. Thus, fixing positions the guide openings 8 apart from the structure to which the guides 6, 7 are fixed.

[0099] Each guide opening 8 extends through the guides 6, 7 in a first direction d1. Each guide opening 8 has a side slot 8a that is open, or at least openable, in a second direction d2 orthogonal to the first direction d1, such that, during the method, the rope 1 is moved into or out of the guide opening 8 via the side slot 8a in the transverse direction of the rope. The guides 6, 7 preferably include one or more latching members 8b that are positionable to close the slots 8a and displaceable to open the slots 8a. The one or more latching members 8b are arranged to prevent the rope 1 from being displaced from its slot 8a when positioned to close the slot 8a.

[0100] In a preferred embodiment, the guide is fork-shaped. Each guide opening 8 is preferably elongated, particularly in the second direction d2, as shown. The elongated shape facilitates easy positioning of the cord 1 in the guide opening 8 when the cord 1 is not tensioned, and prevents the cord 1 from being accidentally removed from the guide opening 8.

[0101] The guides 6 , 7 preferably comprise or consist of plastic.

[0102] The method, in particular arrangement [A1], comprises positioning only one rope 1 in each opening 8 of the rope guides 6, 7. This is then preferably done via the side grooves 8a, in particular by moving the rope 1 in its transverse direction via the side grooves 8a.

[0103] In the following, reference Figure 18-20 The preferred structure of the rope clamping device 5 is described in more detail. In a preferred embodiment, the clamping device 5 includes a clamp body 5a, a locking member 5c, and a fixing device for fixing the rope clamping device 5 to the car 3. The clamp body 5a includes a plurality of openings 5b extending through the clamp body 5a in a first direction D1.

[0104] The method, in particular arrangement [A1], comprises clamping each rope 1, in particular the end section 1a of each rope 1, with a clamping device 5. The clamping of each rope 1 comprises bending a loop 9 from the end section 1a of each rope 1 and inserting the loop 9 through an opening 5b of the clamp body 5a from a first side s1 of the clamp body 5a, and inserting a locking member 5c through the loop eyelet of the loop 9 on a second side s2 of the clamp body 5a, in particular thereby preventing the loop 9 from returning to the first side s1 by the locking member 5c. The locking member 5c is inserted through the loop eyelet of the loop 9 in a second direction D2, which is orthogonal to the first direction D1. Thus, it prevents the loop 9 from returning to the first side s1, and thus achieves a clamping effect. In a preferred embodiment, a common locking member 5c is inserted through the loop eyelet of all the ropes 1.

[0105] In a preferred embodiment, each opening 5b of the clamp body 5a extends in a direction D3 that is orthogonal to the first direction D1. Each loop 9 of the cord 1 is inserted through a single opening. The direction D3 is also orthogonal to the second direction D2, so that the opening 5b positions and holds the loop 9 in a position such that the eyelet 9a of the loop 9 extends through the loop 9 in the direction D2 and the locking element 5c can be easily inserted into the eyelet.

[0106] In arrangement 100, the clamping device 5 is mounted on the car 3, in particular fixed to the handrail 3b of the car 3, preferably fixed with a strap 5d. Thus, arrangement A1 comprises mounting the clamping device 5 on the car 3 by fixing the clamping device 5 to the car 3, for example a handrail of the car 3, preferably with a strap 5d.

[0107] Figure 21 A preferred construction of the rope 1 is shown. In this case, the rope 1 is a coated rope, in particular comprising one or more load-bearing members 1a coated with a surface material 1b. Preferably, the surface material is non-metallic. Preferably, the surface material is a polymer or at least comprises a polymer. The polymer may be, for example, polyurethane, polyethylene, rubber or silicone. Other coating materials may also be used. The coating comprising a polymer material increases the frictional engagement between the rope 1 and the rope pulley 4. Thus, the rope pulley 4 can be rotated, for example by pulling the rope 1, without slipping occurring between them. The coating 1b of the rope 1 also facilitates the use of, for example, reference Figure 18-20 The specific solution of the locking member 5c described above provides a secure grip. The coating also contributes to good friction during elevator use, which helps keep the hoist compact. The coating 1b of the rope 1 also makes the rope 1 more sensitive to shocks. To keep the rope 1 safe and unharmed, good control during installation is beneficial. In the context of coated ropes, the rope installation method described in this application, as well as the apparatus and tools used therein, are advantageous due to the increased control of the rope 1 during installation.

[0108] The rope is preferably thin, preferably having a diameter of less than 10 mm. This is advantageous because a smaller diameter drive pulley 4 can be used. Due to their relatively small bending radius, such ropes can be stored in compact, small-radius rope reels. This helps them fit efficiently within the space above the car, which advantageously facilitates the rope installation according to the present invention. For example, an installer has space to stand next to the rope reel on top of the car and arrange the rope around the rope pulley 4. Thin ropes also facilitate the compactness of the hoisting function, reducing motor torque requirements, contributing to the compactness of the mechanical components, and the hoist itself, making it easier to fit the hoist within the hoistway, particularly with the hoist edge next to the cabin's protrusion. Thin ropes also reduce rope weight and increase the number of ropes, which can make the rope more difficult to control. In the context of thin ropes, the rope installation method described herein, as well as the apparatus and tools used therein, are advantageous due to increased control of the rope 1 during installation and / or the space efficiency of the rope 1.

[0109] It is generally preferred that the rope wheel 4 is in a freely rotatable state during said moving elevator car 3. During said moving elevator car 3, the rotation of the rope wheel 4 can be caused by the movement of the rope 1, without slipping between the rope 1 and the rope wheel 4.

[0110] It is generally preferred that the rope sheave 4 is a driving sheave of a hoisting machine M, which comprises a motor 10 for rotating the rope sheave 4. The hoisting machine M is preferably mounted in the upper end t of the hoistway H.

[0111] In the freely rotatable state, preferably, the brake of the hoist M is not in a braking state, and the motor 10 of the hoist M is not in an energized state for generating electricity on the wheel 4 to generate torque to brake the wheel 4 or rotate the wheel 4.

[0112] It is generally preferred that the hoist 11 is operable to move vertically raising or lowering the elevator car 3 relative to the rope sheave 4. It is generally preferred that the hoist 11 is a temporary hoist 11 and is removed in the method after the ropes 1 are installed.

[0113] It is generally preferred, although not essential, that the temporary hoist 11 comprises a hoisting machine 11a mounted on the car 3 and a hoisting member 11b which is movable by the hoisting machine 11a and arranged to be supported from above the car 3, e.g. Figure 1 In this case, the hoisting member 11 b more specifically bypasses the diverting member 11 c mounted above the car 3 and connected to the car 3. It is generally preferred that in the arrangement 100 the elevator car is suspended by the hoist 11.

[0114] It is generally preferred that the guide opening 8 of the guide 6 and / or 7 is mounted so that the rope 1 extends in a row between the rope wheel 4 and the guide 6, 7 in question, which row is preferably without twist, but not necessarily, as some twist may be acceptable, for example a twist of up to but preferably less than 45 degrees.

It will be apparent to those skilled in the art that the present invention can be implemented in various ways. Therefore, as those skilled in the art will appreciate in light of the above teachings, the above-described embodiments of the present invention may be modified or altered without departing from the present invention. Therefore, it should be understood that the present invention and its embodiments are not limited to the above-described examples, but may vary within the scope of the claims.
