Description

Technical Field

[0001] The invention relates to a method and a device for installing elevator guide rails. Background Art

[0002] An elevator may include a car, a shaft, a hoisting machinery, ropes, and a counterweight. A separate or integrated car frame may surround the car.

[0003] A lifting machine may be positioned in the shaft. The lifting machine may include a drive, a motor, a traction sheave, and a mechanical brake. The lifting machine may move the car up and down in the shaft. The mechanical brake may stop the rotation of the traction sheave, thereby also stopping the movement of the elevator car.

[0004] The car frame can be connected to the counterweight by ropes via a traction sheave. The car frame can also be supported on guide rails extending in the vertical direction in the shaft using sliding devices. The guide rails can be attached to the side wall structure in the shaft using fastening brackets. The sliding devices hold the car in place in the horizontal plane when the car moves up and down in the shaft. The counterweight can be supported on the guide rails attached to the wall structure of the shaft in a corresponding manner.

[0005] The car may transport people and / or freight between landings in a building.The wall structure of the shaft may be formed of solid walls, open beam structures, or any combination thereof.

[0006] The guide rail can be formed by a certain length of guide rail elements. The guide rail elements can be connected end to end in the elevator shaft during the installation phase. The guide rail elements can be attached to each other using a connecting plate extending between the ends of two consecutive guide rail elements. The connecting plate can be attached to the continuous guide rail element. The ends of the guide rail can include some form of shape locking device to correctly position the guide rails relative to each other. Using a supporting device, the guide rail can be attached to the wall of the elevator shaft at a supporting point along the height of the guide rail.

[0007] The installation of guide rails according to the prior art methods involves considerable complexity, including transporting, lifting and positioning the guide rails during elevator installation. The time required to install the guide rails according to the prior art methods is also long. These problems become more serious in modern high-rise buildings. Summary of the invention

[0008] It is an object of the present invention to provide an improved method and apparatus for elevator guide rail installation.

[0009] The shaft is first measured using a measuring device in order to determine the shape of the shaft and the positions of the fixing points for the guide rails along the shaft height based on the measurement results.

[0010] The adjustable fastening bracket is then attached to the guide rail and the fastening bracket is adjusted based on the information received during the measurement phase. This can be done before the guide rail is installed in the shaft.

[0011] The invention means that during installation of the guide rail, a guide rail element provided with a fastening bracket can be lifted in the shaft and attached to a fastening point in the wall of the shaft without further adjustment of the fastening bracket.

[0012] The invention simplifies and shortens the time required for installation of the guide rail compared to prior art solutions, in which fastening brackets are attached to the guide rail elements in the shaft and the fastening brackets are subsequently adjusted during installation of the guide rail.

[0013] In an embodiment, the guide rail element can be lifted upward in the shaft by means of a lift connected to a transport device comprising a hook device and a lever device. The hook device can be attached to the upper end of the guide rail element, and the lower end of the guide rail element can be slidably supported on a row of already installed guide rail elements with the lever device. Thus, the guide rail element can be lifted in a controlled manner, i.e. the guide rail does not swing during lifting.

[0014] In order to obtain new guide rail elements, the lowering of the transport device can also be done in a controlled manner.When moving downwards, the lever device can also be slidably supported on the already installed guide rail elements in the row.

[0015] In one embodiment, the hook device can move up and down in the shaft without being connected to the installed rail elements in rows. In this embodiment, during the upward and downward movement in the shaft, only the lever device can move slidingly on the installed rail elements in rows.

[0016] On the other hand, the hook device can also be slidably supported on the row of already installed guide rail elements. In this embodiment, during the downward movement in the shaft, the hook device can be slidably moved on the row of already installed guide rail elements. In this embodiment, during the upward movement in the shaft, the hook device may not be connected to the row of already installed guide rail elements.

[0017] In all embodiments, the hook device may be fixedly attached to the upper end of the guide rail element during lifting of the guide rail element.

[0018] Before installing the guide rail and / or during manual installation of the first lowermost portion of the guide rail element and / or during installation of the guide rail, a transport platform that can be moved up or down in the shaft by means of a lift can be used in order to attach the guide rail element to the wall in the shaft. Attaching the guide rail element to the wall in the shaft can be done manually by a technician from the transport platform or automatically by a robot from the transport platform.

[0019] In an embodiment, each end of the guide rail element may also be provided with a joining clamp. When the joining clamps are connected to each other, and thus when two consecutive guide rail elements are connected to each other, the joining clamps can form a plug-in joint between the joining clamps themselves, and thus between two consecutive guide rail elements.

[0037] Figure 1 A side view is shown, and Figure 2 A horizontal cross section of an elevator is shown.

[0038] The elevator may include a car 10, an elevator shaft 20, a hoisting machine 30, ropes 42, and a counterweight 41. A separate or integrated car frame 11 may surround the car 10.

[0039] A lifting machine 30 may be positioned in the shaft 20. The lifting machine may include a drive 31, a motor 32, a traction sheave 33, and a mechanical brake 34. The lifting machine 30 may move the car 10 upward and downward in the vertically extending elevator shaft 20 in a vertical direction Z. The mechanical brake 34 may stop the rotation of the traction sheave 33, thereby also stopping the movement of the elevator car 10.

[0040] The car frame 11 may be connected to a counterweight 41 by ropes 42 via a traction sheave 33. The car frame 11 may also be supported on guide rails 25 extending in the vertical direction in the shaft 20 by means of a sliding device 27. The sliding device 27 may include rollers that roll on the guide rails 25, or sliding seats that slide on the guide rails 25, when the car 10 moves up and down in the elevator shaft 20. The guide rails 25 may be attached to the side wall structure 21 in the elevator shaft 20 by means of a fastening bracket 26. The sliding device 27 holds the car 10 in place in a horizontal plane when the car 10 moves up and down in the elevator shaft 20. The counterweight 41 may be supported on the guide rails attached to the wall structure 21 of the shaft 20 in a corresponding manner.

[0041] The wall structure 21 of the shaft 20 may be formed by a solid wall 21, an open beam structure or any combination thereof. Thus, one or more walls may be solid and one or more walls may be formed by an open beam structure. The shaft 20 may include a front wall 21A, a rear wall 21B and two opposing side walls 21C, 21D. There may be two guide rails 25 for the car 10. The two car guide rails 25 may be positioned on the opposing side walls 21C, 21D. There may also be two guide rails 25 for the counterweight 41. The two counterweight guide rails 25 may be positioned on the rear wall 21B.

[0042] The guide rail 25 can extend vertically along the height of the elevator shaft 20. Therefore, the guide rail 25 can be formed by a certain length (for example 5m) of guide rail elements. The guide rail elements 25 can be installed end to end one after another. The guide rail elements 25 can be attached to each other using a connecting plate extending between the ends of two consecutive guide rail elements 25. The connecting plate can be attached to the continuous guide rail elements 25. The ends of the guide rails 25 can include some form of locking device to correctly position the guide rails 25 relative to each other. The guide rails 25 can be attached to the wall 21 of the elevator shaft 20 using a supporting device at a supporting point along the height of the guide rails 25.

[0043] The car 10 may transport people and / or cargo between landings in a building.

[0044] Figure 2 Plumb lines PL1, PL2 are shown in the shaft 20, which can be produced by plumbing the shaft 20 before installing the elevator. The plumb lines PL1, PL2 can be formed with a conventional rope, or with a light source, such as a laser with a beam directed upward along the plumb lines PL1, PL2. A global measurement reference in the shaft 20 usually requires a plumb line and a gyroscope, or two plumb lines.

[0045] Figure 1 A first direction S1 is shown, which is the vertical direction in the elevator shaft 20 . Figure 2 A second direction S2 is shown, which is the direction between the guide rail (DBG) and a third direction S3, which is the direction from the rear wall to the front wall (BTF) in the shaft 20. The second direction S2 is perpendicular to the third direction S3. The second direction S2 and the third direction S3 are perpendicular to the first direction S1.

[0046] Figure 3 An arrangement for mounting the rail is shown.

[0047] The figures show five landings L1 - L5 in the shaft 20 , but of course any number of landings may be present in the shaft 20 .

[0048] The first elevator H1 may be arranged in the shaft 20 to move the transport platform 500 upward and downward in the shaft 20. The first elevator H1 may be suspended from a ceiling of the shaft 20.

[0049] The second elevator H2 may be arranged in the shaft 20 to move the transport device 600 upward and downward in the shaft 20. The second elevator H2 may be suspended from the ceiling of the shaft 20.

[0050] The transport platform 500 can be supported by rollers on opposite solid walls 21 in the shaft 20. The transport platform 500 does not need to be connected to the guide rails 25 in any way. The transport platform 500 can be used to transport one or more technicians and / or one or more robots and / or tools in the shaft 20. The horizontal cross section of the transport platform 500 can be provided with a passage for the guide rails 25. The transport platform 500 can be used to measure the shaft before the elevator is installed and / or for mounting the guide rails to the walls 21 of the shaft 20 and / or for aligning the guide rails 25 after the elevator is installed.

[0051] The storage area SA can be arranged on the first level L1. The storage area SA can be arranged at any position below the working height of the guide rail installation as a matter of course. The storage area SA can be first positioned on the first level L1 and then repositioned to a higher level as the installation proceeds. The guide rail elements 25 can be stored on the storage area SA, and the guide rail elements 25 can be lifted using the transport device 600. The guide rail elements 25 can be manually loaded on the transport device 600.

[0052] First, the shaft 20 can be measured using a measuring device 800 positioned on the transport platform 500. The results of the measurement can then be used to determine the shape of the shaft 20 and the positions of the fastening points for the guide rails 25 along the height of the shaft 20.

[0053] Then, based on the information received in the measuring phase, the adjustable fastening bracket 50 may be attached to the guide rail 25. The fastening bracket 50 may be further adjusted based on the information received in the measuring phase.

[0054] Before installing the guide rail 25 in the shaft 20, the shaft 20 can be measured and the fastening bracket 50 can be installed and adjusted. The fastening and adjustment of the fastening bracket 50 to the guide rail element 25 can be carried out at the elevator installation site. The guide rail element 25 provided with the fastening bracket 50 should be marked so that the guide rail element 25 can be identified later when the guide rail element 25 is installed. The guide rail element 25 provided with the fastening bracket 50 belongs to a specific row of guide rail elements 25 and belongs to a specific height position in a specific row of guide rail elements 25.

[0055] The first lowermost portion of the guide rail 25 may be manually installed into the shaft 20. The transport platform 500 may be used to manually install the first portion of the guide rail 25 into the shaft 20.

[0056] The figure shows a situation in which the first guide rail element 25 in the second part of the guide rail 25 is lifted upward in the shaft 20 by means of a transport device 600 connected to the second hoist H2. The transport device 600 may include a hook device 300 connected to the second hoist H2 and a lever device 400, and a lever device 400 connected to the hook device 300. The hook device 300 may be connected to the second hoist H2 by means of a first line 350. The lever device 400 may be connected to the hook device 300 by means of a second line 360. The lever device 400 may include an upper lever portion 410 and a lower lever portion 420. The upper lever portion 410 and the lower lever portion 420 may be connected to each other by means of a lever arm 430.

[0057] The upper end of the guide rail element 25 may be attached to the hook device 300 and thereby also to the second hoist H2.

[0058] The lower end of the guide rail element 25 to be lifted may be attached to the upper lever portion 410. The lower lever portion 420 may be slidably supported on the rows of guide rail elements 25 already installed.

[0059] Therefore, the guide rail element 25 can be lifted along the rows of already installed guide rail elements 25 using the second lift H2 and the transport device 600. The upper end of the guide rail element 25 can be firmly attached to the hook device 300. Therefore, the lifting force is transmitted from the second lift H2 to the hook device 300, and further to the guide rail element 25. The lower end of the guide rail element 25 can be attached to the upper lever part 410. The lower lever part 420 can slide on the rows of already installed guide rail elements 25. During the upward movement, the lower lever part 420 can be slidably connected to the rows of already installed guide rail elements 25.

[0060] The guide rail element 25 can be lifted along the row of already installed guide rail elements 25 to a height at which the lower lever portion 420 reaches the upper end of the row of already installed guide rail elements 25 .

[0061] The guide rail element 25 can then be disconnected from the lever device 400. Thereafter, the lower end of the guide rail element 25 can be connected to the upper ends of the row of already installed guide rail elements 25. Finally, the guide rail element 25 can be attached to the wall 21 of the shaft 20.

[0062] Thereafter, using the second hoist H2, the transport device 600 can be moved downward along the rows of already installed rail elements 25. When moving downward, the lever device 400 can slide on the rows of already installed rail elements 25. The lever device 400 can be slidably supported on the rows of already installed rail elements 25. In an embodiment, the hook device 300 can be slidably supported on the rows of already installed rail elements 25 during the downward movement of the hook device 300 in the shaft.

[0063] The control unit 700 can be used to control the measurement, store the information received from the measurement, and perform calculations based on the information received from the measurement. The control unit 700 can also send the information received from the measurement to a display device. Based on the displayed information, the fastening bracket on the guide rail element 25 can be attached and aligned.

[0064] Figure 4 Means for engaging the rail are shown.

[0065] The figure shows one possibility of joining two consecutive rail elements 25 together with joining fixtures 100, 200 provided on the rail elements 25. The figure shows the lower end of an upper rail element 25 and the upper end of a lower rail element 25. Two rail elements 25 are to be joined together.

[0066] The cross section of the guide rail element 25 may have the shape of the letter T, with a flat bottom 25A and a flat support portion 25B, which protrudes outward from the middle of the bottom 25A. The guide rail element 25 may be attached to the wall 21 in the shaft 20 from the bottom 25A of the guide rail element 25 by means of a fastening bracket. The support portion 25B of the guide rail element 25 may form two opposite side support surfaces and one end support surface of a support seat for the car 10 or the counterweight 41. The support seat may be provided with sliding surfaces or rollers, which act on the support surface of the support portion 25B of the guide rail element 25.

[0067] Each rail element 25 may be provided with a first engagement clamp 100 attached to a first end of the rail element 25 and a second engagement clamp 200 attached to a second, opposite end of the rail element 25. The first end of the rail element 25 may be the lower end of the rail element 25, and the second end of the rail element 25 may be the upper end of the rail element 25. The drawings show the first engagement clamp 100 on the lower end of the upper rail element 25 and the second engagement clamp 200 on the upper end of the lower rail element 25.

[0068] Each rail element 25 may be provided with a transverse through hole in the bottom 25B of the rail element 25 at each end of the rail element 25. On the other hand, the first engaging fixture 100 and the second engaging fixture 200 may be provided with corresponding threaded holes. Bolts may pass through the holes in the bottom in the rail element 25 into the threaded holes in the first and second engaging fixtures 100, 200 so as to attach the first and second engaging fixtures 100, 200 to the ends of the corresponding rail elements 25. Thus, the engaging fixtures 100, 200 are positioned on the opposite surface of the bottom of the rail 25 relative to the support portion of the rail 25.

[0069] The first outer end of the first engagement fixture 100 can be roughly flush with the lower end of the guide rail element 25. The first engagement fixture 100 can include a male connector element 110, which extends outward from the first end of the first engagement fixture 11 in the longitudinal direction. The longitudinal direction can be consistent with the longitudinal direction of the guide rail element 25. The male connector element 110 can be adapted to be inserted into the corresponding female connector element 210 in the second engagement fixture 200. The male connector element 110 can have equal axial lengths B1. On the other hand, the axial lengths B1 of the male connector element 110 can be staggered. The benefit of using male connector elements 110 with staggered axial lengths B1 will be that the first engagement fixture 100 and the second engagement fixture 200 can be guided to the correct position in one direction at a time. The first engagement fixture 100 and the second engagement fixture 200 can be pre-set in the correct position on the guide rail element 25. When using male connector elements 110 with equal axial lengths B1, this pre-setting is beneficial.

[0070] The male connector element 110 may be formed by a pin. The cross section of the pin may be circular. The female connector element 210 may be formed by a hole. The cross section of the hole corresponds to the cross section of the pin.

[0071] In this embodiment, the number of male connector elements 110 and the number of female connector elements 210 are three, but there may be any number of male connector elements 110 in the first joining jig 100 and a corresponding number of female connector elements 210 in the second joining jig 200. Thus, there may be at least one male connector element 110 in the first joining jig 100 and at least one female connector element 210 in the second joining jig 200. The three male connector elements 110 and the three female connector elements 210 may be positioned in the corners of a triangle.

[0072] The number of male connector elements 110 in the first joining jig 100 and the number of female connector elements 220 in the second joining jig 200 may be equal.

[0073] The first joining fixture 100 and the second joining fixture 200 can form a plug-in joint between two consecutive guide rail elements 25 .

[0074] The first joining jig 100 may be produced such that a through hole is bored in the longitudinal direction of the first joining jig 100. Then, the male connector element 110 is inserted into the hole and attached in the hole with a pressure connector. Thus, a blind hole extending from the second inner end of the first joining jig 100 into the first joining jig 100 will remain.

[0075] The first outer end of the second engagement jig 200 may be substantially flush with the upper end of the guide rail element 25. The second engagement jig 200 may include a hole 210 that enters the second engagement jig 200 along a longitudinal direction from the first end of the second engagement jig 200. The longitudinal direction may coincide with the longitudinal direction of the guide rail element 25. The hole 210 may be a through hole that passes through the second engagement jig 200.

[0076] When the pin 110 of the first engagement fixture 100 is completely pushed into the hole 210 of the second engagement fixture 200, the two continuous guide rail elements 25 will be in the correct position relative to each other. Subsequently, the first end surface of the first engagement fixture 100 and the first end surface of the second engagement fixture 200 are positioned relative to each other. In this position, the opposite surfaces of the two continuous guide rail elements 25 are also positioned relative to each other.

[0077] The weight of the one or more upper rail elements 25 will hold the first joining clamp 100 and the second joining clamp 200 together. The rail elements 25 will of course be attached to the wall 21 of the shaft 20 using fastening brackets, thereby eliminating movement of the rail elements 25 in any direction. Therefore, a separate locking between the first joining clamp 100 and the second joining clamp 200 may not be required. If desired, a separate locking between the first joining clamp 100 and the second joining clamp 200 may of course be provided. The locking may be implemented as a snap-on locking between the first joining clamp 100 and the second joining clamp 200.

[0078] Another possibility is to provide the outer end of the middlemost pin 110 with a thread, for example. When the first joining fixture 100 and the second joining fixture 200 are joined together, the middlemost pin 110 can be made long enough so that the outer end of the pin protrudes from the opposite end of the second joining fixture 200. A nut can then be screwed onto the thread of the middlemost pin 110 to lock the two joining fixtures 100, 200 together.

[0079] The opposite end surfaces of two consecutive guide rail elements 25 may also be provided with a form lock. One end surface may be provided with a groove, while the opposite end surface may be provided with a protrusion which sits in the groove.

[0080] The first joining jig 100 and the second joining jig 200 may be made of cast iron or aluminum.

[0081] The pin 110 in the first joining fixture 100 may be made of cold drawn steel bars. On the other hand, the pin 110 may also be made of plastic.

[0082] The outer ends of the pins 110 in the first joining fixture 100 may be grooved to help align the pins 110 into the holes 210 in the second joining fixture 200 .

[0083] Figure 5 A hook device of a transport device is shown.

[0084] The hook device 300 may include a main body 310 and two locking members 320, 330 pivotably attached to the main body 310. Each locking member 320, 330 may include two parallel rockers spaced apart from each other. The rocker may be pivotally supported via a first shaft 311 on the main body 310. A second shaft 312 may pass between the outer ends of the rocker. The second shaft 312 may protrude upward from the upper rocker. The rocker may be spring-loaded. In the accompanying drawings, the locking members 320, 330 are shown in an open position. When the tension in the first line 350 is transmitted to the first lift H1, the locking members 320, 330 are turned into a locked position. The outer ends of the locking members 320, 330 provided with the second shaft 312 will therefore turn toward each other so that the outer ends of the second shaft 312 protrude into the corresponding holes 211, 212 in the second engagement fixture 200 attached to the end of the guide rail element 25.

[0085] When the tension in the first wire 350 transmitted to the first elevator H1 is released, the locking members 320, 330 will turn to the open position shown in the drawings. The hook 300 will fall downward so that the outer ends of the second shafts 312 of the locking members 320, 330 will fall out of the corresponding holes 211, 212 in the second engagement fixture 200. The spring device will then push the locking members 320, 330 into the open position shown in the drawings.

[0086] When the locking members 320, 330 are in the open position, the hook device 300 can slide down along the row of already installed rail elements 25 when the first lift H1 releases the first support line 350 from the first lift H1 to the hook 300. When the first support line 350 is released from the first lift H1, the weight of the hook device 300 will ensure that the hook device 300 slides down along the row of already installed rail elements 25.

[0087] Figure 6 A lever arrangement of a transport device is shown.

[0088] The lever device 400 comprises an upper lever part 410 and a lower lever part 420. The lower lever part 420 slides on the already installed guide rail 25. The upper lever part 410 accommodates the lower end of the guide rail element 25 to be lifted. The upper lever part 410 can be connected to the lower lever part 420 via a lever arm 430.

[0089] Figure 6The lever device 400 is shown during the lifting of a guide rail element 25. The lower lever part 420 of the lever device 400 slides on the row of guide rails 25 already mounted to the wall 21 of the shaft 20. The lower end of the guide rail element 25 to be lifted is supported on the upper lever part 410 of the lever device 400. The lever arm 430 can be pivotally attached to the upper lever part 410 and the lower lever part 420 of the lever device 400. The lever arm 430 is shown in an inclined position forming a first operating position. The lever arm 430 can be locked in this first operating position so that the guide rail element 25 to be lifted is kept at a distance from the guide rails 25 already mounted to the wall 21 of the shaft 20. The upper lever part 410 is at a distance A1 from the row of already mounted guide rail elements 25. This distance A1 leaves space outside the row of already mounted rail elements 25 for the passage of the rail element 25 provided with the first joining fixture 100 when the rail element 25 is lifted.

[0090] Figure 7-9 The lever device of the transport device is shown in different positions.

[0091] The second lift H2 may be connected to the transport device 600 (i.e., to the hook device 300 of the transport device 600 located at the upper end of the transport device 600) using the first wire 350. The lever device 400 of the transport device 600 may be connected to the hook device 300 using the second wire 360 ​​(see FIG. Figure 3 ).

[0092] Figure 7 The lever device 400 is shown in a position in which the lever device 400 just reaches the upper end of a row of already mounted guide rail elements 25 .

[0093] Figure 8 The lever device 400 is shown in a position in which the lower part 420 of the lever device has come to rest at the upper end of the row of already installed guide rail elements 25. The locking of the lever arm 430 has been released and the lever arm 430 has been extended relative to the longitudinal direction of the row of already installed guide rail elements 25 into a straight position.

[0095] Fig.10 A cross section of a guide rail is shown.

[0096] The cross section of the guide rail element 25 may have the shape of the letter T, with a flat bottom 25A and a flat support portion 25B, which protrudes outward from the middle of the bottom 25A. The guide rail element 25 may be attached to the wall 21 in the shaft 20 from the bottom 25A of the guide rail element 25 by means of a bracket. The support portion 25B of the guide rail element 25 may form two opposite side support surfaces 25B1, 25B2 and one end support surface 25B3 of a support seat for the car 10 or the counterweight 41. The support seat may be provided with sliding surfaces or rollers, which act on the support surfaces 25B1, 25B2, 25B3 of the support portion 25B of the guide rail element 25.

[0097] The hook device 300 and the lever device 400 (i.e., the upper lever portion 410 and the lower lever portion 420) may be provided with rollers 441, 442 or sliding seats that roll or slide on the inner thinner portion 25B4 of the support portion 25B of the guide rail 25. The rollers 441, 442 or sliding seats may be positioned at the transition portion between the lower thinner portion 25B4 and the outer thicker portion 25B5 of the support portion 25B of the guide rail 25. The rollers 441, 442 in the hook device 300 will keep the hook device 300 fixed to the guide rail 25 during the downward movement of the hook device 300 on the row of already installed guide rail elements 25. The rollers 441, 442 in the lower lever portion 420 will keep the lever device 400 fixed to the guide rail 25 during the upward and downward movement of the lever device 400 on the row of already installed guide rail elements 25. During the upward movement of the transport device 600 on the guide rail 25 , the rollers 441 , 442 in the upper lever portion 410 will keep the lower end of the guide rail element 25 fixed to the upper lever portion 410 .

[0098] The rollers 441, 442 may be movably supported in the hook device 300 and the lever device 400. As can be seen in the drawings, the rollers 441, 442 may be moved between a first position in which the rollers 441, 442 are in contact with the guide rail and a second position in which the rollers 441, 442 are out of contact with the guide rail. When the rollers 441, 442 are in the second position, the hook device 300 and the lever device 400 may be disconnected from the guide rail 25.

[0099] Fig.11 A transport platform is shown.

[0100] The transport platform 500 may include a bottom plane 510 and a ceiling plane 520, the ceiling plane 520 being positioned at a vertical distance above the bottom plane 510. The bottom plane 510 may form a work surface for one or more technicians and / or one or more robots. A vertical support rod 530 may extend between the bottom plane 510 and the ceiling plane 520. At opposite ends of each plane 510, 520 in the transport platform 500, two support rollers 540 are provided. The support rollers 540 support the transport platform 500 on the opposite walls 21 in the shaft 20. When the transport platform 500 moves up and down in the shaft 20, the support rollers 540 keep the transport platform 500 approximately in a horizontal plane. The transport platform 500 may also be further provided with a locking device for locking the transport platform to the wall 21 in the shaft 20. The locking device may be implemented by a hydraulic cylinder acting on two opposite walls 21 in the shaft 20.

[0101] Bypass channels 550, 551 for lifting the guide rail element 25 during installation of the guide rail 25 may also be formed in the transport platform 500. The bypass channels 550, 551 may be formed by recesses protruding inwardly from the periphery of the transport platform 500. The bypass channels 550, 551 also provide space for the plumb lines PL1, PL2 to bypass the transport platform 500.

[0102] The transport platform 500 may be provided with measuring equipment for measuring the shape of the shaft 20 and / or for measuring the position of the fastening points of the guide rails 50 in the shaft 20 and / or the position of the transport platform 500 in the shaft 20. The transport platform 500 may be provided with measuring devices MD10, MD11, MD12 and MD13 for measuring the position of the transport platform 500 relative to the shaft 20. Once the transport platform 500 is locked in the shaft 20, the measuring devices MD10, MD11, MD12 and MD13 can determine the position of the transport platform 500 in the shaft 20 based on the plumb lines PL1, PL2. The measuring devices MD10, MD11, MD12 and MD13 can measure based on sensors without contacting the position of the plumb lines PL1, PL2 formed by the wire. Another possibility is to use a laser light source at the bottom of the elevator shaft (e.g. to generate an upwardly directed light beam), which can be measured using the measuring devices MD10, MD11, MD12 and MD13 on the transport platform 500. The measuring devices MD10, MD11, MD12 and MD13 may be light-sensitive sensors or digital imaging devices that measure the hit point of the light beam generated by the light source. The light source may be a robotic total station, where the measuring devices MD10, MD11, MD12 and MD13 will be reflectors that reflect the light beam back to the robotic total station. The robotic total station will then measure the position of the measuring devices MD10, MD11, MD12 and MD13.

[0103] The transport platform 500 may also be provided with a distance measuring device MD15, MD16 for measuring the vertical position, ie the height position of the transport platform 500 in the shaft 20. The distance measurement may be based on laser measurement.

[0104] Fig.12 A fastening bracket is shown.

[0105] The fastening bracket 50 may be formed of two separated bracket parts 60, 70 that are movably attached to each other. The first bracket part 60 may have the shape of the letter L with a vertical portion 61 and a horizontal portion 62. The second bracket part 70 may also have the shape of the letter L with a vertical portion 71 and a horizontal portion 72. The first bracket part 60 may be attached to the guide rail 25, and the second bracket part 70 may be attached to the wall 21 in the shaft 20. The horizontal portions 62, 72 of the two bracket parts 60, 70 may be adjustably attached to each other.

[0106] The vertical portion 61 of the first bracket portion 60 may be attached to the bottom portion 25A of the guide rail 25 using a clamp 65 and a bolt 66 .

[0107] The vertical portion 71 of the second bracket part 70 can be attached to the wall 21 in the shaft 20 using an anchor bolt 76. The vertical portion 71 in the second bracket part 70 can include an oblong opening 75, which is open at the lower end of the vertical portion 71 in the second bracket part 70. Before starting to install the guide rail 25, holes for the anchor bolts 76 can be drilled into the wall 21 of the shaft 20 at predetermined locations. The anchor bolts 76 can be screwed into the holes. The anchor bolts 76 can be screwed only partially into the thread, so that the head of the anchor bolt 76 is at a distance from the fastening surface.

[0108] The horizontal portion 62 of the first bracket portion 60 and the horizontal portion 72 of the second bracket portion 70 can be attached to each other using bolts passing through oblong openings in the horizontal portion 62 of the first bracket portion 60 and the horizontal portion 72 of the second bracket portion 70. The oblong openings can be sized so that the position of the first bracket portion 60 can be finely adjusted relative to the second bracket portion 70 so that the guide rail 25 can be aligned.

[0109] The fastening bracket 50 may be mounted to a predetermined position on the guide rail element 25 to be installed before the guide rail element 25 to be installed is lifted in the shaft 20 .

[0110] When the lever arm 430 is turned to the second operating position, the fastening bracket 50 that had been attached to the guide rail element 25 before the guide rail element 25 was lifted will be positioned just above the bolt 76. Lowering the guide rail element 25 to be installed will also lower the fastening bracket 50 attached to the guide rail element 25 so that the oblong opening 75 slides over the bolt 76.

[0111] Tightening of the bolts 76 will attach the second bracket part 70 of the fastening bracket 50 to the wall 21 in the shaft 20. The bolts 76 can be tightened from the transport platform 500 by a technician or with a robot.

[0112] Another possibility is to drill the anchor holes during the installation of the guide rail 25. This can be done manually or automatically from the transport platform 500.

[0113] After mounting the guide rails 25 to the respective walls 21 in the shaft 20, the guide rails 25 may be aligned. Alignment of the guide rails 25 may be accomplished in any known manner.

[0114] Fig.13 A vertical cross section of a shaft illustrating measurements of the shaft is shown.

[0115] On the left side of the figure an upper fastening point FP1 and a lower fastening point FP2 are shown in connection with the first side wall 21 of the shaft 20. The two fastening points FP1, FP2 are located at a vertical distance Z1 from each other. Using fastening brackets 50, the guide rail element 25 will be fastened to the fastening points FP1, FP2.

[0116] On the right side of the figure an upper fastening point FP3 and a lower fastening point FP4 are shown in connection with the second opposite side wall 21 of the shaft 20. The two fastening points FP3, FP4 are located at a vertical distance Z2 from each other. Using fastening brackets 50, the guide rail element 25 will be fastened to the fastening points FP3, FP4.

[0117] The figure also shows vertical plumb lines PL1, PL2 in the shaft 20. Thus, the distances X1, X2 from the plumb lines PL1, PL2 to the closest fastening points FP1, FP3 can be measured. These distances X1, X2 are therefore measured in the direction between the guide rails (DBG).

[0118] Fig.14 A horizontal cross section of a shaft is shown illustrating measurements of the shaft.

[0119] On the left side of the figure in connection with the first side wall 21 of the shaft 20 two fastening points FP1R, FP1L are shown, which are located at a distance from one another in a horizontal plane in the shaft 20. These two fastening points FP1R, FP1L are intended for a fastening bracket 50. As can be seen in 12, the fastening bracket 50 is attached to the first side wall 21 of the shaft 20 from two support points FP1R, FP1L.

[0120] Two fastening points FP3R, FP3L are shown on the left side of the figure in connection with the second opposite side wall 21 of the shaft 20, which are located at a predetermined distance from one another in a horizontal plane in the shaft 20. The two fastening points FP3R, FP3L are intended for a fastening bracket 50.

[0121] The distance Y1 from the first plumb line PL1 to the nearest left fastening point FP1R can be measured. The distance from the second plumb line PL2 to the nearest right fastening point FP3L can also be measured in a corresponding manner. The distance between the left fastening points FP1L, FP1R is known, as is the distance between the right fastening points FP3L, FP3R. The distance in the direction between the rear wall and the front wall of the shaft (BTF) is thus measured.

[0122] These measurements may be completed from the transport platform 500 prior to installing the elevator.

[0123] Fig.15 The attachment of the fastening bracket to the rail is shown.

[0124] The figure shows a display device 710 that can be connected to the control unit 700. Based on the information received from the display device 710, the fastening bracket 50 can be attached to the correct position on the rail element 25. The display device 710 can show the distance Z12 to the lower fastening bracket 50 and the distance Z11 to the upper fastening bracket 50 measured from the lower end of the specific rail element 25. Therefore, the technician can first retrieve the distance information Z11, Z12 for a specific rail element 25 (for example GR13) from the display device 710, after which the technician can attach the fastening bracket 50 to the correct position on the specific rail element 25.

[0125] Fig.16 Adjustment of the fastening bracket is shown.

[0126] The accompanying drawings show a display device 710 that can be connected to the control unit 700. Based on the information received from the display device 710, the fastening bracket 50 can be attached to the correct position on the guide rail element 25. The display device 710 can show the BTF adjustment point on the line scale formed on the fastening bracket 50. There can be a single reference line on the second bracket part 70, and there can be multiple adjacent lines on the first bracket part 60. The display device 710 can also show the DBG adjustment points on both sides of the fastening bracket 50 on the line scale formed on the fastening bracket 50. There can be multiple adjacent lines on the second bracket part 70. The lower edge of the first bracket part 60 can form a single reference line. Therefore, the technician can first retrieve the BFT and DGB adjustment information for a specific guide rail element 25 (e.g., GR13) and a specific fastening bracket (e.g., FB1) from the display device 710, and then the technician can adjust the specific fastening bracket FB1 to the correct position on the specific guide rail element 25.

[0127] Also shown are oblong openings 68 in the horizontal portions 62, 72 of the two bracket parts 60, 70, and bolts 67 attaching the two bracket parts 60, 70 to each other. Also shown are clamps 65 and bolts 66 for attaching the first bracket part 60 to the rail 25.

[0128] Fig.17 A first embodiment of a guide rail pre-setting workbench is shown.

[0129] The guide rail pre-setting workbench 800 may include a frame 801 , a joining jig setting unit 810 , 820 at each end of the frame 801 , and a guide rail straightening unit 850 in a middle portion of the frame 801 .

[0130] The guide rail element 25 can be positioned in the frame 801 and attached to the frame 801 from both ends and in the middle using the fastening devices 802,803,804 provided on the frame 801. After this, the straightness of the guide rail element 25 can be measured. The fastening device 804 on the middle part of the frame 801 can be used to force the guide rail element 25 to be straight. The size and flatness of the interface surfaces 25F1,25F2 of the guide rail element 25 for the joint fixture 100,200 can be checked to a common reference. Then the correct number and / or thickness of the shims can be installed to the correct position on the interface surfaces 25F1,25F2 based on the previous measurement of the guide rail interface surfaces 25F1,25F of the joint fixture 100,200. After this, the joint fixture 100,200 can be attached to the interface surfaces 25F1,25F2 of the guide rail element 25, so that the shims ensure the correct position of the joint fixture 100,200. The interface surfaces 25F1 , 25F2 may be standard interface surfaces provided on the rail elements 25 for attaching a connecting plate between the ends of two consecutive rail elements 25 .

[0131] The fastening of the joining clamps 100, 200 to the guide rail element 25 can be done manually on a workbench. However, the fastening of the joining clamps 100, 200 to the guide rail element 25 can also be done partially or completely automatically in a workbench.

[0132] Fig.18 A second embodiment of a guide rail pre-setting workbench is shown.

[0133] The guide rail pre-setting workbench 800 may include a frame 801 , a joining fixture setting unit 810 , 820 at each end of the frame 801 , a fastening bracket setting unit 830 , 840 at each end of the frame 801 , and a guide rail straightening unit 850 in the middle portion of the frame 801 .

[0134] The fastening bracket setting units 830 , 840 may move in a longitudinal direction of the frame 801 along a guide rod 835 provided on the frame 801 .

[0135] The fastening bracket 50 may be attached to the rail element 25 using the fastening bracket setting units 830, 840. The fastening bracket setting units 830, 840 may be used in order to position the fastening bracket 50 to the correct position on the rail element 50. Thereafter, the fastening bracket 50 may be adjusted in the manner as previously described.

[0136] The fastening of the fastening bracket 50 to the guide rail element 25 can be done manually on a workbench. However, the fastening of the fastening bracket 50 to the guide rail element 25 can also be done partially or completely automatically in a workbench.

[0137] The adjustment of the fastening bracket 50 can also be done manually on the workbench. However, the adjustment of the fastening bracket 50 can also be done partly or completely automatically in the workbench.

[0138] In order to enable automatic installation and / or adjustment of the joining fixtures 100, 200 and / or the fastening brackets 50 on the guide rail element 25, the guide rail pre-setting workbench 800 can be provided with several servo motors in combination with: joining fixture setting units 810, 820; fastening bracket setting units 830, 840; and guide rail straightening unit 850. A mixture of automatic steps and manual steps can also be used in this combination.

[0139] The use of joining clamps 100, 200 at the ends of the rail elements 25 is another advantageous option of the present invention. However, the joining clamps 100, 200 are not necessary in the present invention. The rail elements 25 can be provided with only fastening brackets 50 and connecting plates, which are attached to the upper interface surfaces 25F1, 25F2 of the rail elements 25 to be lifted in the shaft 20. The hook device 300 can be attached to the upper end of the rail element 25, entering the step between the rail element 25 and the connecting plate. Then, the connecting plates will be used instead of the joining clamps 100, 200 to connect the consecutive rail elements 25 to each other.

[0140] The measuring device 800 positioned on the transport platform 500 for measuring the shaft 20 can be formed by any measuring device suitable for the purpose of measuring the shape of the shaft 20 and the position of the fastening points in the shaft 20. The measuring device 800 can be formed by a single measuring device or a plurality of measuring devices. The measuring device 800 can be formed by a plurality of low-cost distance measuring sensors, such as radar and / or ultrasonic and / or laser distance sensors and / or inductive sensors, which are arranged to scan the shaft 20 in order to achieve the measurement results required in the present invention.

[0141] The measuring device 800 can of course also be formed by a laser scanner and a 3D vision system. However, these systems are based on detecting measurements from a 3D point cloud and therefore require a lot of memory and computing power. The calculations are also time-consuming. Therefore, these systems may not be the best choice for the measuring device 800 in the present invention.

[0142] The figures show an embodiment in which only one second lift H2 with a transport device 600 is used. During installation, the suspension point of the second lift H2 must be changed. Each row of guide rail elements 25 to be installed will require an own suspension point for the second lift H2. Several second lifts H2 can of course be suspended from the ceiling of the shaft 20. Therefore, each second lift H2 will be provided with its dedicated transport device 600. This will mean that several rows of guide rails 25 can be installed simultaneously into the shaft 20.

[0143] The present invention is not limited to the fastening bracket 50 shown in the figures. Any kind of adjustable fastening bracket 50 can be used in the present invention.

[0144] The shaft 20 in the figure is for only one car 10, but the present invention can of course be used in a shaft intended for a plurality of cars 10. Such an elevator shaft 10 can be divided into sub-shafts for each car 10 having reinforcement. Horizontal reinforcements can be provided at predetermined intervals along the height of the shaft 20. Then, a portion of the guide rail 25 is attached to the reinforcement in the shaft 20. Another portion of the guide rail 25 is attached to the solid wall 21 in the shaft 20.

[0145] The present invention can be used in low-rise or high-rise buildings. In high-rise buildings, the benefits of the present invention are naturally greater. The lifting height of high-rise buildings can exceed 75 meters, preferably exceed 100 meters, more preferably exceed 150 meters, and most preferably exceed 250 meters.

[0146] The use of the invention is not limited to the elevators disclosed in the accompanying drawings. The invention can be used in any type of elevator, for example, elevators with a machine room or without a machine room, elevators with a counterweight or without a counterweight. The counterweight can be placed on any side wall, both side walls or the rear wall of the elevator shaft. The drive, motor, traction sheave and mechanical brake can be located in the machine room or at a certain position in the elevator shaft. The car guide rails can be located on opposite side walls of the shaft or on the rear wall of the shaft in so-called rack elevators.

[0147] It is obvious to a person skilled in the art that, as technology advances, the inventive concept can be implemented in various ways.The invention and its embodiments are not limited to the examples described above but may vary within the scope of the claims.
