Description

Technical Field

[0001] The invention relates to an elevator device and a method for building an elevator. The elevator is preferably an elevator for transporting passengers and / or freight. Background Art

[0002] With so-called skip elevators, the bottom of the elevator shaft is put into use before the building is completed. In this case, the upper part of the building and the top of the elevator shaft can be built simultaneously, because the elevator moving in the bottom of the elevator shaft is already serving people on the lower floors of the building being built. Typically, in a skip elevator, during construction, the elevator car moving in the lower part of the elevator shaft is supported and moved by a hoist supported on a support structure that is vertically movable in the elevator shaft.

[0003] When the elevator shaft being constructed above the vertically movable support structure has reached a sufficient stage of completion, the completed section of the elevator shaft can be put into service. At this stage, a "jump" is performed, in which the vertically movable support structure is lifted higher in the elevator shaft. Thereafter, the car can reach a higher position than before the jump and start serving additional floors.

[0004] During use of the car for transporting passengers and / or cargo beneath the movable support structure, the car may be suspended from the movable support structure by hoist ropes suspended from the movable support structure.

[0005] One disadvantage of the known solutions is that it is particularly difficult to optimize the layout of the entire installation so as to simultaneously meet the many demanding requirements of a jump elevator. This is largely due to the fact that temporary and repeated changes are made in the configuration. It is difficult to find good working positions for the components. The requirements of a jump elevator generally relate to space efficiency, safety, simplicity, time consumption, safety and smoothness of the process steps associated with the jump, process costs and generally also to the simplicity of subsequently converting the elevator under construction into a finished elevator. For example, the positioning of vertically extending elevator components such as ropes and guide rails sets many restrictions on the positioning of other components. In addition, the space requirements at different locations are more or less different, and it is problematic to design a layout that works well at many locations. Summary of the invention

[0006] The object of the invention is to introduce an improved elevator device and a method for building an elevator. One object is in particular to introduce a solution by which one or more of the above-mentioned problems of the prior art and / or the disadvantages discussed or suggested elsewhere in the specification can be solved. One object is in particular to make it easier to meet the requirements of an elevator, in which the operating area of ​​the elevator car can be extended to a higher level as the construction process proceeds.

[0007] Specific embodiments are proposed, by which the freedom of positioning the elevator components is increased. Specific embodiments are proposed, by which the adaptability of the device is adapted to different locations and hoistways of different sizes.

[0008] A new elevator device is proposed, comprising a hoistway; and one or more vertically oriented guide rails in the hoistway for guiding the vertical movement of one or more movable elevator units; and one or more movable elevator units, installed in the hoistway and vertically movable along the one or more guide rails, comprising at least one elevator car, preferably also including a counterweight; and a lifting rope; and a movable support structure installed in the hoistway for supporting the one or more movable elevator units below it through the lifting ropes; and a hoist located on the movable support structure for moving the lifting ropes, thereby moving the one or more movable elevator units. The movable support structure comprises a main body part and a shelf structure protruding laterally from the main body part, and the hoist is installed on the shelf structure.

[0009] With this solution, one or more of the above objects can be achieved. With this solution, the freedom to position the elevator components is easier due to the increased ability and freedom to adapt and position the hoisting machine, especially close to the shaft wall or equivalent lateral limiting structure, which is advantageous because the hoisting machine is an important key component for determining the position of other components of the elevator installation, such as the hoisting ropes for suspending the car. This solution reduces in particular the dependence of the position of the hoisting machine on other variables, such as the structure of the movable support structure and its mounting system, and on the position of other elevator components. This solution is also applicable to service shafts in different locations with shafts of different sizes.

[0044] In a preferred embodiment, the lift is movable between the first position and the second position by a horizontal movement, preferably by a linear horizontal movement or by pivoting about a vertical axis. This is an alternative to the above-mentioned movability by pivoting. Preferably, then, the lift is slidably mounted movably between the first position and the second position. Preferably, then, the device comprises a guide device for guiding the movement between said positions, preferably a guide member and a guide rail along which the guide member is guided and movable, wherein the lift comprises the guide member and the support structure (e.g. its support platform) comprises the guide rail, or vice versa.

[0069] Figure 1 The elevator device 100 according to the first embodiment is shown, in particular, the elevator device during construction. Figure 6An elevator installation 200 according to a second embodiment is shown, in particular an elevator installation for construction. In both embodiments, the elevator installation 100, 200 comprises a shaft 1; 21 and vertically oriented guide rails 2, 3; 22, 23 for guiding the vertical movement of movable elevator units 4, 5. The installation comprises movable elevator units 4, 5; 24, 25, mounted in the shaft 1; 21, vertically movable along guide rails 2, 3; 22, 23. The guide rails 2, 3; 22, 23 have been schematically shown. The movable elevator units 4, 5; 24, 25 in this embodiment comprise an elevator car 4; 24 and a counterweight 5; 25. Each elevator unit 4, 5; 24, 25 is arranged to obtain lateral support from the guide rails for guiding the vertical movement of the movable elevator unit 4, 5; 24, 25, in particular by means of guides (not shown), such as roller guides or sliding guides, included in said movable elevator units 4, 5; 24, 25. The elevator arrangement 100, 200 further comprises hoisting ropes 6; 26; 24, 25 connected to the movable elevator units 4, 5 and a movable support structure 7; 27 mounted in the hoistway 1; 21 for supporting the movable elevator units 4, 5; 24, 25 thereunder via the hoisting ropes 6, 26. Furthermore, the elevator arrangement comprises a hoisting machine 8; 28 on the movable support structure 7; 27 for moving the hoisting ropes 6; 26 and thereby the movable elevator units 4, 5; 24, 25. The movable support structure 7; 27 comprises a body part 9; 29 and a shelf structure 10; 30 protruding laterally from the body part 9, the hoisting machine 8; 28 being mounted on the shelf structure 10; 30. The shelf structure 10; 30 is rigidly connected to the body part 9; 29 and in particular has a horizontal beam 9a; 29a protruding laterally therefrom. The shelf structure 10; 30 is in particular a cantilever shelf structure.

[0070] In a preferred embodiment, the hoisting machine 8; 28 comprises a motor 8a; 28a and a drive wheel 8b; 28b rotatable by the motor 8a; 28a for moving the hoisting ropes 6, 26. The hoisting ropes pass around the drive wheel 8b; 28b. In a preferred embodiment, the apparatus comprises an elevator control system 90 connected to the hoisting machine 8; 28 for controlling its operation.

[0071] like Figure 1 and 6 As shown, the shelf structure 10;30 comprises a support base 105;31 on which the lift 8;28 is mounted to rest.

[0072] In the following, it is described Figure 1 Preferred features of the embodiments. Figure 3 and 4As shown, each vertically oriented guide rail line 2, 3 of the elevator installation comprises guide rail sections 2a, 3a arranged one above the other, while the hoisting machine 8 is movable between a first position and a second position. Figure 3 The lifting machine 8 is shown in its first position, Figure 4 The hoist 8 is shown in its second position. In the first position, the hoist 8 is located on top of the uppermost rail segment 2a, 3a of one or more vertically oriented rail lines 2, 3 and below the rail support 15 installed in the hoistway 1, so that the vertical projection of the hoist 8, in particular the vertical projection of the motor and / or its drive wheel, overlaps with the vertical projection of the rail segment 2a, 3a and the rail support 15. In the second position, the hoist 8 is displaced so that the vertical projection of the hoist 8, in particular the vertical projection of the motor and / or its drive wheel, and the vertical projection of the rail segment 2a, 3a and the rail support 15 are adjacent to each other (i.e. do not overlap). Preferably, here in particular the vertical projection of the rail segment is equal to the vertical projection of its upper end face. The defined movability facilitates that the hoist 8 can be relatively freely placed in a position where its drive wheel is positioned so that the hoist ropes 6 pass close to the rails. This also facilitates free placement of the hoist, so that at the end of the construction time involving the jumps and lifts of the movable support structure, the final machine (which can even be the same as during construction) can be placed to be supported by the rails that have been used during construction. Likewise, since the hoist position does not necessarily need to be moved sideways, extensive rewiring of the hoist ropes often required in conversions can be avoided. These all contribute to a fast and efficient conversion after the construction phase.

[0073] In order to facilitate good support and the aforementioned movability, the support base 105 comprises a vertical open passage 105a, which is located on top of the uppermost guide rail segments 2a, 3a and through which the additional guide rail segments to be mounted on top of the uppermost guide rail segments extend when the hoist is in the second position. The vertical open passage 105a is located below the guide rail bracket 15 mounted in the hoistway. When the movable support structure 7 is lifted higher in the hoistway 1, the guide rail bracket 15 is adapted to move through the passage 105a so that the support base 105 rises to the level of the guide rail bracket 15 or above the level of the guide rail bracket 15, in particular when the hoist 8 is in the second position. In the second position, the hoist 8 blocks the passage 105a at least in the vertical direction.

[0074] As shown in the figure, the vertical opening channel 105a is preferably also open laterally, so that the guide rail bracket 15 installed in the hoistway is suitable for extending into the channel 105a from the lateral side. Therefore, the bracket 15 can maintain a mechanical connection with the hoistway structure in which it is installed, for example, one end thereof can remain fixed to the wall or beam of the hoistway without causing a collision when the movable support structure 7 is lifted so that the support base 7 rises to the level of the guide rail bracket 15 or above the level.

[0075] like Figure 2 As shown schematically, preferably the projection of the upper face of the uppermost guide rail segment 2a, 3a of the one or more guide rail lines 2, 3 is completely within the vertical projection of the passage 105a. The floor of the elevator 8 is not visible in order to show the passage 105a more clearly.

[0076] exist Figure 3 In a preferred embodiment of the invention, the lift 8 is preferably pivotally displaceable between the first position and the second position, preferably about at least one horizontal axis 314, such as Figure 4 As shown. Figure 3 In a preferred embodiment of the invention, this is achieved in that the lift is mounted on the shelf structure 10, in particular on its supporting base 105, and is pivotably movable between a first position and a second position by means of one or more hinges 106.

[0077] like Figure 3 As shown, the shelf structure 10 includes beam structures 101 - 104 that carry all or at least part of the weight of the lift 8 .

[0078] The beam structures 101-104 include horizontally oriented beam portions that protrude laterally from the main body portion 9. Figure 1 In the embodiment of the invention, the entire weight of the hoist 8 is carried in particular by the horizontally oriented beam section, or by the horizontally oriented beam section and at least one auxiliary boom 32 .

[0079] The beam structure 101-104 comprises two and in the present case in particular only two horizontally oriented beam parts 101, 102, which protrude laterally from the main body part 9, in particular from its horizontal beam 9a, adjacent to each other, and the two horizontally oriented beam parts 101, 102 are spaced apart so that a space is formed between them. This structure contributes to the rigidity of the shelf structure 10.

[0080] The beam structures 101 - 104 further include vertically oriented beam portions 103 , 104 protruding vertically upward from the aforementioned horizontally oriented beam portions 101 , 102 .

[0081] As mentioned above, the shelf structure 10 comprises a support base 105 on which the hoist 8 is mounted to rest. The support base 105 is preferably mounted with the aforementioned beam structure, for example by welding or bolts, preferably in particular on the aforementioned one or more vertical or inclined beam sections 103, 104. Thus, it can be arranged in an elevated position relative to the horizontal plane where the shelf is connected to the main body 9.

[0082] like Figure 3 As shown, the movable support structure 7 comprises one or more guides 11 (only one is shown) mounted on the movable support structure 7 for guiding the vertical movement of the movable support structure 7 during the lifting of the movable support structure 7 along the guide line 2, which in the embodiment shown is the guide line 2 of the elevator car. Each of the guides 11, 31 is suitable for running along the guide line 2, which in the embodiment shown is the guide line 2 of the elevator car. For this purpose, each of the guides can be, for example, a sliding guide as shown in the figure, or alternatively, a rolling guide, which are known components of elevators.

[0083] Figure 5 An alternative way of moving the lift 8 is shown. In this alternative embodiment, the lift can be moved between the aforementioned first and second positions by horizontal movement, for example by linear horizontal movement or by pivoting about a vertical axis.

[0084] exist Figure 5 In the embodiment, the lift is mounted to be slidably displaceable between a first position and a second position. To facilitate the movement, the device may include a guide device for guiding the lift 8 to move between the positions, such as a guide member rigidly connected to the lift 8 and a guide rail rigidly connected to the support base, or vice versa, and wherein the guide member is movably guided by the guide rail.

[0085] Below, refer to Figure 6-8 describe Figure 6 Preferred features of the embodiments. Figure 7 As shown, the shelf structure 30 comprises beam structures 201-204 which bear part of the weight of the hoist (8). The beam structures 201-204 comprise horizontally oriented beam portions 201, 202 which protrude laterally from the main body portion 29, in particular from its horizontal beam 29a. Figure 7 In the embodiment of FIG. 2 , the entire weight of the lifting machine 8 is carried in particular by the horizontally oriented beam sections 201 , 202 and the at least one auxiliary boom 32 .

[0086] The beam structure 201-204 comprises two, in the present case in particular only two, horizontally oriented beam sections 201, 202. These protrude laterally from the main body 29, in particular from its horizontal beam 29a, adjacent to each other. The two horizontally oriented beam sections 201, 202 are spaced apart so as to form a space between them. This structure contributes to the rigidity of the shelf structure 30.

[0087] The beam structures 201-204 further include vertically oriented beam portions 203, 204 protruding upward at an oblique angle from the aforementioned horizontally oriented beam portions 201, 202.

[0088] As mentioned above, the shelf structure 30 comprises a support base 31 on which the hoist 8 is mounted to rest. The support base 31 is preferably mounted on the aforementioned beam structure 201-204, for example by welding or bolts, and is particularly preferably mounted on the aforementioned one or more vertical or inclined beam sections 203, 204. Thus, it can be arranged in an elevated position relative to the horizontal plane where the shelf is connected to the main body section 29.

[0089] exist Figure 6 In a preferred embodiment of the invention, the shelf structure 30 is partially suspended from above by at least one auxiliary suspension rod 32. Figure 7 and 8 As shown more precisely in FIG. 1 , the device comprises at least one auxiliary suspension rod 32 which engages the shelf structure 30 and a portion 29b of the movable support structure 27 which is higher than the shelf structure 30. This contributes to the rigidity of the shelf structure 30.

[0090] The auxiliary suspension rod 32 comprises an elongated tension member 32a, in particular a rope, cable, rod or chain, for transmitting tension between the shelf structure 30 and the aforementioned portion 29b of the movable supporting structure 27.

[0091] The at least one auxiliary hanger 32 may include one or two auxiliary hangers, such as defined tension members.
