Description

Technical Field

[0001] This invention relates to a movable machine room for an elevator, an elevator assembly, and a method for constructing an elevator. The elevator is preferably an elevator used for transporting passengers and / or goods. Background Technology

[0002] In a so-called duplex elevator, the bottom of the elevator shaft is already in use before the building is completed. In this case, the upper part of the building and the area above the elevator shaft can be constructed simultaneously as the elevator moves at the bottom of the shaft, which already serves the lower floors of the building under construction. In duplex elevators, the elevator car, moving at the bottom of the shaft, is typically supported and moved during construction using a hoist supported by a vertically movable machine room within the elevator shaft.

[0003] When used for transporting passengers and / or goods below the mobile equipment room, the car can be suspended below the mobile equipment room via lifting ropes.

[0004] Typically, construction work within the shaft above a vertically movable equipment room is carried out by working on an installation platform suspended above and movable above the movable equipment room, or alternatively, by working on scaffolding installed within the shaft.

[0005] Once the elevator shaft above the vertically movable machine room is sufficiently completed, the finished section of the elevator shaft can be put into use. At this stage, a "floor jump" is performed, in which the vertically movable machine room is raised higher within the elevator shaft. Afterward, the elevator car can reach a higher position than before the floor jump and begin serving other floors.

[0006] One drawback of existing technology is that construction work above a mobile machine room requires the installation of complex equipment and platforms within the shaft. Summary of the Invention

[0007] The object of this invention is to introduce an improved method for constructing elevators. In particular, it is to introduce a solution that addresses one or more of the aforementioned problems of the prior art and / or the disadvantages discussed or implied elsewhere in the specification. A particular object is to enable the simple and safe construction of duplex elevators above a movable machine room.

[0008] A novel mobile equipment room is proposed, comprising: a support platform for a hoist, the support platform including one or more releasable mounting mechanisms for releasably mounting the mobile equipment room in a shaft; and a hoist mounted on the support platform; a work platform on the support platform, the work platform preferably forming the top of the mobile equipment room and / or including handrails; and at least one support structure supporting the work platform on the support platform; and wherein each support structure is selectively actuated, particularly to obtain a reaction force from the support platform to extend vertically to raise the work platform to a position higher than above the support platform, or to retract vertically to lower the work platform back toward the support platform.

[0009] This solution enables the achievement of one or more of the aforementioned objectives. Specifically, it simplifies and safely facilitates the construction of a multi-level elevator above a movable machine room. It allows for forward and backward movement and enables operations at different heights above the support platform. It also allows for operations at relatively high positions above the support platform, followed by the lowering of the work platform back towards the support platform. Furthermore, it allows for a compact reconfiguration of the movable machine room and its relatively easy and rigid vertical lifting to higher positions within the shaft.

[0010] The following will describe preferred further details of the mobile data center, which can be combined with the mobile data center alone or in any combination.

[0011] In a preferred embodiment, the movable equipment room includes an operating interface operable to control the actuation of at least one support structure that can be selectively actuated. This facilitates actuation operation.

[0012] In a preferred embodiment, the user interface is in the form of an operation panel, such as a button panel or a touch screen.

[0013] In a preferred embodiment, the operating interface is connected to an actuation device of at least one support structure of the movable computer room that can be selectively actuated.

[0014] In a preferred embodiment, the operating interface is mounted on the structure of the work platform, such as being fixedly mounted on the structure of the work platform, or mounted on a retainer fixedly mounted on the structure of the work platform. Therefore, personnel on the work platform can elevate themselves to the optimal working position.

[0015] In a preferred embodiment, the support platform bears the entire weight of the work platform via at least one selectively actuable support structure.

[0016] In a preferred embodiment, the support structure extends upon actuation, preferably actuable to extend vertically by at least 2 meters from a retracted state, for raising the work platform by at least 2 meters. For example, in many locations, a substantially long distance is sufficient to allow the work platform to be moved vertically from a location near one (landing) floor to a location near another (landing) floor, allowing for easy installation of landing door components and / or access to / from the work platform. Similarly, for example, in many locations, a substantially long distance is sufficient to allow the work platform to be moved vertically from a location near one support to a location near another support.

[0017] A novel elevator device is also proposed, comprising: a shaft and a movable machine room as described anywhere above or below in this application, the movable machine room being installed in a transport position in the shaft vertically supported on a fixed structure; and an elevator car located in the shaft below the movable machine room.

[0018] This solution can achieve one or more of the aforementioned objectives.

[0019] Preferred further details of the device will be described below, which may be combined with the device alone or in any combination.

[0020] In a preferred embodiment, the apparatus includes a lifting device for lifting the mobile equipment room, the lifting device receiving support from a support structure installed above the mobile equipment room, preferably a support structure installed in a shaft above the mobile equipment room.

[0021] In a preferred embodiment, the apparatus includes a lifting device for raising the mobile equipment room, the lifting device being separate from at least one support structure that can be selectively actuated.

[0022] In a preferred embodiment, the support platform bears the entire weight of the work platform via at least one support structure that can be selectively actuated.

[0023] A novel method for constructing an elevator is also proposed, comprising: constructing a shaft; and constructing an elevator car within the shaft; and installing a movable machine room to a transport position within the shaft, which is vertically supported on a fixed structure, wherein the movable machine room is as described anywhere above. The method includes, when the movable machine room is installed in the transport position, using the elevator car (for initial use) to transport passengers and / or goods below the movable machine room.

[0024] In a preferred embodiment, the method includes, particularly after the initial use period and after the use of the work platform period, raising the mobile machine room to a second transport position; wherein the second transport position is higher than the first transport position; and then installing the mobile machine room to the second transport position, which is vertically supported in a shaft on a fixed structure; and then, while the mobile machine room is installed in the second transport position, using a (secondary use) elevator car for transporting passengers and / or goods below the mobile machine room.

[0025] In a preferred embodiment, the method includes installing elevator components from a work platform in a portion of the shaft above a support platform when the movable machine room is located at a transport position (I or II) in the shaft. This use includes moving the work platform up and down using at least one support structure that can be selectively actuated.

[0026] In a preferred embodiment, the use of the work platform is performed during initial and / or secondary use. In particular, using the work platform includes, during initial and / or secondary use, simultaneously moving the work platform up and down using at least one support structure that can be selectively actuated.

[0027] In a preferred embodiment, all selectively actuable support structures remain unactable during the lifting of the mobile equipment room. Preferably, each support structure of the mobile equipment room is locked and cannot be extended before the mobile equipment room is lifted upwards. This avoids accidental extension during lifting.

[0028] In a preferred embodiment, each selectively actuable support structure is in a retracted state during the lifting of the mobile equipment room. Thus, the mobile equipment room is compact and can be relatively easily and rigidly lifted vertically to a higher position within the shaft.

[0029] In a preferred embodiment, the use of the work platform includes one or more actuations of the support structure to extend it vertically, thereby raising the work platform to a higher position above the support platform; and one or more actuations of the support structure to retract it vertically, thereby causing the work platform to fall back toward the support platform.

[0030] In a preferred embodiment, the operating platform includes receiving user input via an interface and a support structure that can be selectively actuated based on the user input.

[0031] In a preferred embodiment, using a work platform includes placing the guide rail segment on top of a previously fixed guide rail segment and securing it immovably in the shaft using a bracket.

[0032] In a preferred embodiment, initial and / or secondary use includes receiving a call signal from one or more user interfaces, such as one or more user interfaces and / or mobile user interfaces at a floor and / or inside the elevator car, and moving the elevator car in response to the call signal automatically controlled by the elevator control system.

[0033] In a preferred embodiment, each selectively actuable support structure includes an upright tower that is selectively actuated to extend or retract in a vertical direction.

[0034] In a preferred embodiment, each upright tower includes a plurality of parallel elongated tower members movable along each other. Preferably, the plurality of parallel elongated tower members include at least a first tower member and a second tower member, the first tower member and the second tower member having interlocking profiles movable along each other.

[0035] In a preferred embodiment, the elongated tower members are vertically oriented beams, and the supporting structure includes actuation devices for moving the tower members relative to each other to extend or retract the tower.

[0036] In a preferred embodiment, the actuation device includes a motor arranged to rotate a drive wheel, around which a flexible member, such as a belt (or alternatively a cable or chain), passes, and the rotation of the wheel is arranged to move the flexible member. The flexible member is preferably arranged to pass over a wheel mounted on the upper end of the first tower member and return downwards to a fixed point at the lower end of the second tower member, or to a wheel mounted on the lower end of the second tower member, which specifically forms a support point at which the flexible member can support the second tower member via the wheel. Thus, rotation of the motor in one direction is arranged to pull the second tower member upwards relative to the first tower member, and rotation of the motor in the other (i.e., opposite) direction is arranged to allow the second tower member to move downwards relative to the first tower member under the influence of gravity.

[0037] In a preferred embodiment, the support structure includes a scissor jack mechanism that can be selectively actuated to extend or retract in the vertical direction.

[0038] In a preferred embodiment, the method includes installing vertical guide rails in the shaft to guide the movement of the elevator car and / or the movable machine room.

[0039] In a preferred embodiment, the mobile equipment room, and in particular the support platform for the mobile equipment room, includes guides for guiding the vertical movement of the mobile equipment room along the vertical guide rails of the elevator car.

[0040] In a preferred embodiment, during each lifting process of the mobile equipment room, the vertical movement of the mobile equipment room is guided by one or more guides contained in the mobile equipment room, which extend along one or more guide rails.

[0041] In a preferred embodiment, during the lifting process of the mobile equipment room, the mobile equipment room is lifted using a lifting device that receives support from a support structure installed above the mobile equipment room, preferably a support structure installed in the shaft above the mobile equipment room.

[0042] In a preferred embodiment, during the lifting of the mobile data center, the mobile data center is lifted using a lifting device that is separated from at least one support structure that can be selectively actuated.

[0043] In a preferred embodiment, each use of the elevator car to transport passengers and / or goods includes receiving a call signal from one or more user interfaces, preferably at a floor and / or inside the elevator car, and moving the elevator car in response to the call signal automatically controlled by the elevator control system.

[0044] In a preferred embodiment, each installation of the mobile equipment room is performed using at least one releasable installation mechanism. The releasable installation mechanism is preferably capable of switching between a first state and a second state, wherein in the first state the mechanism engages with a fixed structure to obtain support from the fixed structure, and in the second state the mechanism is released from engagement.

[0045] In a preferred embodiment, the releasable mounting mechanism includes an arm movable to a first state in which the arm vertically overlaps with a bracket immovably fixed in the shaft, and the arm is movable to a second state in which the arm does not overlap with the bracket, such that when the arm is lifted together with the movable machine room, the arm can bypass the bracket positioned above the aforementioned bracket.

[0046] In a preferred embodiment, the releasable mounting mechanism includes an arm movable to a structure above a landing sill or shaft wall, such as (in the latter case) above a recessed surface formed in, for example, a shaft wall or beam, and returning from the structure above the landing sill or shaft wall.

[0047] In a preferred embodiment, each releasable mounting mechanism includes a clamp adapted to releasably clamp a section of the guide rail.

[0048] In a preferred embodiment, in this method, when the mobile equipment room is installed (i.e., in the installation state) at the first transport position and / or the second transport position, the support platform bears the entire weight of the work platform via at least one selectively actuable support structure.

[0049] Preferably, the aforementioned fixing structure includes one or more of the following: a guide rail section of the guide rail, a shaft wall, a floor threshold, a bracket for fixing the guide rail section of the guide rail to the shaft, or (some other) brackets fixed to the guide rail, such as for supporting a mobile machine room.

[0050] In a preferred embodiment, the car has an interior space adapted to accommodate one or more passengers; and a door movable between an open and closed state to open and close the interior space. This facilitates the safe transport of passengers. Attached Figure Description

[0060] The above aspects, features, and advantages of the present invention will become apparent from the accompanying drawings and related detailed embodiments. Detailed Implementation

[0061] Figure 1An elevator assembly is shown in a stage of a method for constructing an elevator according to one embodiment. The method includes providing a shaft 2 in a building 3 and installing vertical guide rails 10 in the shaft 2 to guide the movement of an elevator car 4. Figure 1 As shown, the method also includes installing the movable machine room 1 into a transport position I in a shaft 2 vertically supported on a fixed structure. The method further includes arranging an elevator car 4 and a counterweight 5 in the shaft 2, and connecting the elevator car 4 and the counterweight 5 using a suspension rope 6 suspended in the shaft 2, supported by the movable machine room 1, and passing over at least one pulley 15 of the movable machine room 1, particularly the pulley of the hoist 14 (not shown), which is preferably a drive wheel capable of rotating with a motor also included in the hoist 14. The method includes using (also referred to as "first use") the elevator car 4 to transport passengers and / or goods below the movable machine room 1 when the movable machine room 1 is installed in transport position I. This transport purpose is... Figure 1 The first use is indicated by arrow a1. This first use preferably includes receiving a call signal from one or more user interfaces 90, such as one or more user interfaces 90 and / or a mobile user interface at a floor and / or inside the elevator car, and moving the elevator car in response to the call signal automatically controlled by the elevator control system 100.

[0062] The mobile machine room 1 includes a support platform 411 for a hoist 14. The support platform 411 includes one or more releasable mounting mechanisms 402 for releasably mounting the mobile machine room 1 in the hoistway 2, and the hoist 14 mounted on the support platform 411. The mobile machine room 1 also includes a work platform 420 above the support platform 411, forming the top of the mobile machine room 1 and including handrails 421, whereby personnel can safely stand on the work platform 420. The mobile machine room 1 also includes two support structures 430-430"", the work platform 420 being supported on the support platform 411 by the support structures 430-430"". The support platform 411 bears the entire weight of the work platform 420 via the support structures 430-430"". The mobile machine room 1 preferably also includes an elevator control system 100 for automatically controlling the movement of the elevator car 4, particularly by automatically operating the machine 14. The control system 100 may alternatively be located in other locations. Figure 8 The image shows an enlarged example of a portion of the movable server room 1.

[0063] Each of the aforementioned support structures 430-430"" can be selectively actuated, particularly to obtain a reaction force from the support platform 411 to extend vertically, thereby raising the work platform 420 to a position higher than above the support platform 411, or retracting vertically to lower the work platform 420 back toward the support platform 411. This enables forward and backward movement and allows work to be performed at different heights above the support platform 411. It also allows work to be performed at relatively high positions above the support platform 411, followed by lowering the work platform 420 toward the support platform 411, thereby making the mobile equipment room 1 compact and relatively easy and rigidly vertically raised to higher positions within the hoistway 2. The term "selectively actuable" means that the support structures 430-430"' can be actuated to extend and retract, and that the extension or retraction can be selectively caused by actuation.

[0064] The actuation mechanism, the extending support structure 430-430", is preferably actuated to extend vertically by at least 2 meters from its retracted state, thereby raising the work platform 420 by at least 2 meters. This substantially achieves the advantages described above. A substantially long distance, preferably at least 2 meters as described above, and even longer, is preferred, for example, in many locations sufficient to allow the work platform 420 to be moved vertically from a position near one landing to a position near another landing, thereby allowing easy installation of landing door components and / or access to / from the work platform. Similarly, a substantially long distance, preferably at least 2 meters, and even longer, is preferred, for example, in many locations sufficient to allow the work platform 420 to be moved vertically from a position near one support to a position near another support, thereby allowing easy installation and / or use of the support, for example, during the installation of the guide rail section or the support itself.

[0065] The method includes installing elevator components from a work platform 420 in a portion of the shaft 2 above a support platform 411 when the movable machine room 1 is located at transport position I within the shaft 2. This installation includes moving the work platform 420 vertically using a selectively actuable support structure 430-430". The vertical movement of the work platform 420... Figure 1 As indicated by arrow a2. The operation is performed using the work platform 420 during initial use. This improves the efficiency of the method. Therefore, the support platform 411 simultaneously provides support for the movable units 420 and 4 above and below it. This helps reduce the number of support devices and corresponding support points.

[0066] The use of the work platform 420 specifically includes one or more actuations of the support structure 430-430"" to extend it vertically, thereby raising the work platform 420 to a higher position above the support platform 411; and one or more actuations of the support structure 430-430"" to retract it vertically, thereby lowering the work platform 420 back toward the support platform 411. Thus, vertical movement a2 is achieved, thereby, for example, the material to be installed, such as the guide rail section 11 or the bracket 12, can be raised to a desired height close to its installation position, and / or the working position can be optimally adjusted. Figure 5 and 6 Further preferred details of the use of the work platform 420, as well as further preferred details of the movable machine room 1 and the elevator assembly, are shown in general. All components (such as ropes 6 or rope supply storage devices) are not shown.

[0067] Preferably, the operating platform 420 includes receiving user input via an operating interface 500, and a support structure that can be selectively actuated based on the user input. For this purpose, the mobile equipment room 1 preferably includes an operating interface 500 operable to control the actuation of the selectively actuated support structure. The operating interface 500 is preferably in the form of an operating panel, such as a button panel or a touch screen. The operating interface 500 is preferably connected, for example, via a wired or wireless connection to an actuation device of at least one selectively actuated support structure 430-430"" of the mobile equipment room 1. Figure 21 As shown. The operating interface 500 is preferably installed on the structure of the work platform 420, as shown. Figures 1 to 6 and Figure 7 As shown. Therefore, a person on the work platform can easily and safely elevate themselves to the optimal working position. Most preferably, the operating interface is fixedly mounted on the structure of the work platform 420, or detachably mounted on a retainer fixedly mounted on the structure of the work platform 420. Therefore, the operating interface can be a fixed interface or a mobile interface. Alternatively, the operating interface 500 can be a mobile device such as a mobile phone or tablet, in which software applications suitable for receiving user instructions are installed and / or run.

[0068] By first using bracket 12 to immovably install multiple guide rail sections 11 into the shaft 2, providing... Figure 1 Guide rail line 10 is shown. (As shown) Figure 5 and Figure 6As shown, as the method continues, the guide rail 10 gradually extends to a higher position by repeatedly placing the guide rail segment 11 on top of the previously fixed guide rail segment 11 and immovably securing it in the shaft 2 with the bracket 12. Therefore, using the work platform 420 preferably involves placing the guide rail segment 11 on top of the previously fixed guide rail segment 11 and immovably securing it in the shaft 2 with the bracket 12. Thus, one or more guide rails 10 can be configured to extend to a higher position during elevator operation. Figure 1 The guide rail segment 11 is shown already positioned appropriately. For clarity, Figure 1 Only one guide rail 10 is shown in this view, positioned behind the elevator car 4. Preferably, another guide rail is positioned on the opposite side of the car 4, such that the car is located between the guide rails 10. Figure 5 and Figure 6 The side views shown are viewed from different angles, and both guide rails 10 are shown in each view.

[0069] Figure 7 The preferred details of the route for rope 6 are shown. In this configuration, one end of rope 6 is fixed to the movable machine room 1, and the rope begins at the fixed point, descends over at least one pulley of the counterweight 5, then ascends over at least one pulley 15, descends again over at least one pulley of the car 4, and then ascends to the movable machine room 1, specifically the releasable rope clamp, and then passes through the rope clamp to a rope supply reservoir, which is in the form of one or more pulleys from which other ropes required in the method can be obtained. The rope supply reservoirs are preferably installed on the movable machine room 1, but can also be alternatively installed in other locations, such as the platform floor or in the shaft pit.

[0070] The above are as follows Figure 1 The step of installing the movable equipment room 1 into the transport position I in the shaft 2, which is vertically supported on a fixed structure, is performed using one or more releasable installation mechanisms 402 included in the movable equipment room 1. Alternatives to the aforementioned fixed structure exist. Preferably, the aforementioned fixed structure includes one or more of the following: a guide rail section 11 of the guide rail line 10, a shaft wall 2a, a landing sill, a bracket securing the guide rail section 11 of the guide rail line 10 to the shaft 2, or (some other) brackets fixed to the guide rail line 10, for example, for supporting the movable equipment room. Preferred alternatives to the installation mechanism 402 will be referred to below. Figures 9 to 11 Further details.

[0071] Following the initial usage period and the period after using the work platform 420, the method includes lifting the mobile equipment room 1 to the second transport location II, such as... Figure 2As shown, the second transport position II is higher than the first transport position I, and then the movable machine room 1 is installed in the second transport position II in the shaft 2, which is vertically supported on the fixed structure, as shown. Figure 3 As shown. Installation is performed using one or more releasable mounting mechanisms 402 contained in the movable equipment room 1. As previously mentioned, alternative fixed structures exist.

[0072] During the process of lifting the mobile equipment room 1 to the second transport position II, it is preferable to use lifting devices 20 and 21 to lift the mobile equipment room. The lifting devices 20 and 21 are supported by the support structure 22 installed in the shaft 2 above the mobile equipment room 1.

[0073] During the lifting of the mobile data center 1, the supporting structure is preferably not actuated, for example, Figure 2 As shown. Preferably, before lifting the movable equipment room 1, each support structure 430-430”” of the movable equipment room 1 is locked and cannot be extended. This avoids accidental extension during lifting.

[0074] After the movable machine room 1 is installed to the second transport position II, the method includes using (also referred to as "secondary use") an elevator car 4 to transport passengers and / or goods below the movable machine room 1 while the movable machine room 1 is installed in the second position II. Figure 3 As shown by arrow a1 in the diagram.

[0075] The secondary use of the elevator car 4 for transporting passengers and / or goods preferably includes receiving call signals from one or more user interfaces 90, particularly one or more user interfaces 90 and / or mobile user interfaces at the floor and / or inside the elevator car, and moving the elevator car 4 in response to the call signals automatically controlled by the elevator control system 100.

[0076] The method includes installing elevator components from a work platform 420 in a portion of the shaft 2 above a support platform 411 when the movable machine room 1 is located in a second transport position II within the shaft 2. This installation includes moving the work platform 420 vertically using a selectively actuable support structure 430-430". The vertically moving work platform 420... Figure 4 As indicated by arrow a2. The work platform 420 is used during secondary use. This improves the efficiency of the method. Therefore, the support platform 411 simultaneously provides support for the movable units 420 and 4 above and below it. This helps reduce the number of support devices and corresponding support points.

[0077] The method may include (not shown) a sequence of lifting, installing and using the elevator car 4 for transportation, which may be repeated once or multiple times, wherein the operation of using the work platform 420 is performed each time the elevator car is used.

[0078] At an appropriate time, especially after at least two uses, the method may include converting the construction-period elevator into the final elevator (not shown). Preferably, the conversion includes one or more of the following: removing the movable machine room 1 from the hoistway 2; constructing a new machine room; removing the ropes 6 of the construction-period elevator and installing the ropes of the final elevator; modifying the rope ratio, preferably including making the suspension ratio of the elevator car of the final elevator 1:1, wherein the suspension ratio of the elevator car of the construction-period elevator is n:1, where n is greater than 1; removing the hoist 14 of the construction-period elevator; installing the hoist of the final elevator; and forming the car of the final elevator wholly or at least partially from the car 4 of the construction-period elevator.

[0079] Generally, preferably, the mobile machine room 1, and especially the support platform 411 of the mobile machine room 1, includes a guide 401 for guiding the mobile machine room 1, especially during lifting, vertically moving along the vertical guide rail 10 of the elevator car 4.

[0080] Generally, to achieve releasable installation and thus temporary installation, the mobile equipment room 1 includes one or more releasable installation mechanisms 402 for releasably installing the mobile equipment room 1 as if it were vertically supported. Preferably, the releasable installation mechanism 402 can switch between a first state and a second state, wherein in the first state, the mechanism engages with a fixed structure to obtain support from the fixed structure, preferably a shaft wall 2a, a landing sill, a bracket securing the guide rail segment 11 of the track line 10 to the shaft, or a bracket fixed to the track line 10, for example for supporting the mobile equipment room, or the guide rail segment 11 of the track line 10, and in the second state, the releasable installation mechanism 402 is released from engagement.

[0081] A preferred embodiment of the releasable mounting mechanism 402 will now be described.

[0082] exist Figure 9 In one embodiment, the releasable mounting mechanism 402 includes an arm movable to a first state in which the arm vertically overlaps with a bracket 12 immovably fixed in the shaft, and the arm is movable to a second state in which the arm does not overlap with the bracket 12, such that when the arm is lifted together with the movable machine room 1, the arm can bypass the bracket positioned above the aforementioned bracket 12. Figure 9 In the first case, the arm can move between different states in a horizontal linear motion, but alternatively, the arm can move between different states in a pivotal motion.

[0083] exist Figure 10In one embodiment, the releasable mounting mechanism 402 includes an arm movable onto and from the structure of the well wall 2a, particularly onto the surface of a recess formed in the well wall 2a. A first state is when the arm extends onto the structure of the well wall 2a, and a second state is when the arm is removed from the structure of the well wall 2a. Figure 10 In particular, in this embodiment, the first state is the state where the arm extends into the recess, and the second state is the state where the arm has been removed from the recess. Alternatively, the structure of the shaft wall 2a can be a beam of the shaft wall, and the surface can be the upper surface of the beam. Alternatively, the structure on which the arm is movable can be a landing sill, i.e., a sill leading to a floor.

[0084] exist Figure 11 In one embodiment, the releasable mounting mechanism 402 includes a clamp 180 adapted to releasably clamp the guide rail segment 11 of the guide rail line 10. In this case, a first state of the releasable mounting mechanism 402 is that the clamp holds the guide rail line 10 using clamping members on the opposite side of the guide rail segment 11 of the guide rail 10, and a second state is that the clamp does not clamp the guide rail 10. Generally, a clamp adapted for releasably clamping the guide rail line 10 can be implemented as a wedge clamp with the wedge direction downwards (e.g., Figure 11 In the embodiments described above, or alternatively, implemented as, for example, a fixed brake caliper or a floating brake caliper. One or both clamping members may be movable to compress and release the compression of the guide rail segment 11 of the guide rail line 10 between the clamping members. If only one clamping member is movable, the clamp preferably has a floating frame (also called a "caliper") known from brake calipers. If both clamping members are movable, the clamp preferably has a fixed frame (also called a "caliper") known from brake calipers. This is Figure 11 The situation in the embodiments.

[0085] Figure 11The embodiment is described more specifically below. The gripper 180 includes a frame 181 having a slit for the guide rail 10; and two wedge-shaped brake shoes 182, which are disposed on opposite sides of the guide rail 10 as gripping members. The brake shoes 182 can be movably supported on the frame 181 from a wedge surface by means of rollers 183. A spring 184 can be disposed between a first end of the brake shoe 182 and the frame 181. The second opposite end of the brake shoe 182 can be supported on a slider 185, which slides within a cylinder 186. A power unit, such as a hydraulic power unit 210, can be provided to power the gripper 180. The hydraulic power unit 210 can include an electric motor 211, a hydraulic pump 212, and a reservoir 250. The hydraulic pump 212 pumps oil from the reservoir 250 to the cylinder 186, thereby moving the slider 185 within the cylinder 186.

[0086] Pressurized fluid is supplied to the plunger 185 in cylinder 186, which overcomes the force of spring 184 and presses the brake shoe 182 downward as shown in the figure. Therefore, the brake shoe 182 is removed from the guide surface of guide rail 10. Thus, the movable housing 1 can move freely on guide rail(s) 10.

[0087] Pressurized fluid is extracted from cylinder 186, which allows brake shoe 182 to move upwards as shown in the figure due to the force generated by spring 184 acting on the second end of brake shoe 182. Therefore, brake shoe 182 moves until it contacts the guide surface of guide rail 10. Thus, support platform 411 becomes locked relative to guide rail 10.

[0088] Hydraulic unit 210 can be provided only for clamp 180. Alternatively, a common main hydraulic unit can be provided on the work platform 420 for all equipment requiring hydraulic power to be applied on the work platform 420. Hydraulic valves can be used to connect different pieces of equipment to the common main hydraulic power unit.

[0089] exist Figure 11 In one embodiment, the clamp 180 includes two wedge-shaped brake shoes 182.

[0090] Alternatively, the clamp 180 can be electromechanically operated. The electromechanical device can be used to press the brake shoe 182 against the force of the spring 184. Deactivating the electromechanical device will cause the brake shoe 182 to actuate against the guide rail 10.

[0091] Besides the variations of the braking structure described above, several other known types of braking mechanisms can be used to achieve the aforementioned braking / clamping function. For example, some elevator systems include a braking system in which clamping of the guide rail is achieved through caliper-like claws and associated friction pads. Such lever-type brakes can be used as another alternative.

[0092] Preferred details of the support structure 430-430” will be described below.

[0093] Figures 12 to 16 An alternative embodiment of the support structure 430-430”” is shown, which can be selectively actuated to extend vertically to raise the work platform 420 to a higher position above the support platform 411, in particular to obtain a reaction force from the support platform 411, or to retract vertically to lower the work platform 420 toward the support platform 411.

[0094] Figure 12 An embodiment is schematically shown in which the support structure 430 includes an upright tower 431 that can be selectively actuated to extend or retract in a vertical direction.

[0095] The upright tower 431 is connected between the working platform 420 and the support platform 411. The upright tower 431 includes a plurality of parallel elongated tower members 432, 433 movable relative to each other. The elongated tower members 432, 433 are vertically oriented beams, and the support structure includes actuating devices 434, 435 for moving the tower members relative to each other to extend or retract the tower 431. The elongated tower members 432, 433 are supported against each other to move relative to each other, such that one tower member guides another tower member, which can be achieved, for example, by placing the tower members in a telescopic structure or arranging them with interlocking profiles that move relative to each other.

[0096] exist Figure 12 In this embodiment, the actuating devices 434, 435 include a motor 434 arranged to rotate a drive wheel 436. A flexible member 435, such as a belt (or alternatively a cable or chain), passes around the drive wheel, and the rotation of the wheel is arranged to move the flexible member 435. The flexible member 435 is arranged to pass over the wheel mounted on the upper end of the first tower member 432 and return downward to a fixed point at the lower end of the second tower member 433. Thus, rotation of the motor in one direction is arranged to pull the second tower member 433 upward relative to the first tower member 432, and rotation of the motor in the other (i.e., opposite) direction is arranged to allow the second tower member 433 to move downward relative to the first tower member 432 under gravity. The flexible member 435 passes around both sides of the drive wheel 436 to a fixed point 438, which is arranged to move together with the second tower member 433, thereby forming a closed loop and eliminating the need for the flexible member 435 to be wound around the drive wheel 436. However, this is another alternative way to implement this embodiment. In this case, one end of the flexible member 435 is fixed to a fixing point at the lower end of the second tower member 433, and the other end is fixed to a fixing point on the drive wheel 436.

[0097] Figure 13An embodiment is schematically shown in which the support structure 430' includes an upright tower 431' that can be selectively actuated to extend or retract in a vertical direction.

[0098] The upright tower 431' is connected between the working platform 420 and the support platform 411. The upright tower 431' includes a plurality of parallel slender tower components 432, 433, and 437 that are movable relative to each other.

[0099] The slender tower members 432, 433, and 437 are vertically oriented beams, and the supporting structure includes actuating devices 434 and 435 for moving the tower members relative to each other to extend or retract the tower 431'. The slender tower members 432, 433, and 437 are supported against each other to move relative to each other, such that one tower member guides another tower member. This can be achieved, for example, by placing the tower members in a telescopic structure or arranging them with interlocking profiles that move relative to each other.

[0100] exist Figure 13In one embodiment, the actuating devices 434, 435 include a motor 434 arranged to rotate a drive wheel 436. A flexible member 435, such as a belt (or alternatively a cable or chain), passes around the drive wheel, and the rotation of the wheel is arranged to move the flexible member 435. The flexible member 435 is arranged to pass over a wheel mounted on the upper end of the first tower member 432 and return downwards to pass over a wheel mounted on the lower end of the second tower member. This wheel, mounted on the lower end of the second tower member, specifically forms a support point at which the flexible member can support the second tower member via the wheel. The flexible member 435 is arranged to pass over and below a wheel mounted on the lower end of the second tower member 433, and again rises over the wheel mounted on the upper end of the second tower member 433, reaching above the wheel and returning downwards to a fixed point on the lower end of the third tower member 437. Therefore, the rotation of the motor in one direction is arranged to pull the second tower member 433 upward relative to the first tower member 432, and the rotation of the motor in the other (i.e., opposite) direction is arranged to allow the second tower member 433 to move downward relative to the first tower member 432 under the influence of gravity. Furthermore, the rotation of the motor in one direction is arranged to pull the third tower member 437 upward relative to the second tower member 433, and the rotation of the motor in the other (i.e., opposite) direction is arranged to allow the third tower member 437 to move downward relative to the second tower member 433 under the influence of gravity. The flexible member 435 passes around both sides of the drive wheel 436 to reach the fixed point 438, which is arranged to move together with the third tower member 437. Thus, the flexible member 435 forms a closed loop and does not need to be wound around the drive wheel 436. However, this is another alternative way to implement this embodiment. In this case, one end of the flexible member 435 is fixed to the fixing point at the lower end of the third tower member 433, and the other end is fixed to the fixing point on the drive wheel 436.

The upright tower 431” is connected between the work platform 420 and the support platform 411. The upright tower 431” includes a plurality of parallel elongated tower members 432, 433 movable relative to each other. The elongated tower members 432, 433 are vertically oriented hydraulic cylinders and pistons, hydraulically and selectively actuated to extend or retract. The support structure includes an actuation device 434” for moving the tower members relative to each other to extend or retract the tower 431. This actuation device includes a hydraulic pump 439a and hydraulic fluid 439b, the hydraulic fluid 439b being stored in a reservoir for pumping into the chamber 439c of the hydraulic cylinder.

[0102] Figure 15An embodiment is schematically shown in which the support structure 430"" includes an upright tower 431"" capable of being selectively actuated to extend or retract in a vertical direction".

[0103] An upright tower 431”” is connected between the working platform 420 and the support platform 411. The upright tower 431”” includes a plurality of parallel, elongated tower members 432, 433 movable relative to each other. The elongated tower members 432, 433 are vertically oriented beams, and the support structure includes actuators 434””, 435 for moving the tower members relative to each other to extend or retract the tower 431””. The elongated tower members 432, 433 are supported against each other for movement relative to each other, such that one tower member guides another, which can be achieved, for example, by placing the tower members in a telescopic configuration or arranging them with interlocking profiles that allow them to move relative to each other.

[0104] exist Figure 15 In one embodiment, the actuating devices 434””, 435 include a motor 434””, the motor 434”” is arranged to rotate a drive wheel 436””, a flexible member 435, such as a cable, belt or chain, passes around the drive wheel, and rotation of the drive wheel 436”” is arranged to move the flexible member 435. Figure 15 In this configuration, a flexible member 435 is spirally wound around a drive wheel 436". The drive wheel is mounted on a movable machine room 1, preferably on a support platform 411. The flexible member 435 is arranged to pass over the wheel mounted on the upper end of the first tower member 432 and return downward to a fixed point 438 at the lower end of the second tower member 433. Thus, rotation of the motor 434" in one direction is arranged to pull the second tower member 433 upward relative to the first tower member 432, and rotation of the motor 434" in the other (i.e., opposite) direction is arranged to allow the second tower member 433 to move downward relative to the first tower member 432 under gravity. The wheel 436" is preferably a traction roller. The actuators 434" and 435 preferably include a traction hoist, such as a Tirak™ hoist, which includes a motor 434" and a drive wheel 436".

[0105] Figure 16 An embodiment is schematically shown in which the support structure 430”' includes a scissor jack mechanism that can be selectively actuated to extend or retract in the vertical direction.

[0106] exist Figure 16 In a preferred embodiment, the scissor jack mechanism includes two support arms 610 and 620 connected via a hinge joint J31. The upper end of each support arm 610 and 620 is connected to the working platform 420 via hinge joints J21 and J22. The lower end of each support arm 610 and 620 is connected to the support platform 411 via hinge joints J11 and J12.

[0107] Each of the hinge joints J11 and J12 at the lower deck 110 and each of the hinge joints J21 and J22 at the upper deck 120 shall be arranged such that the ends of the support arms 610 and 620 are allowed to move relative to each other in the horizontal direction, but are prevented from moving relative to each other in the vertical direction.

[0108] Actuation device 630, particularly actuator 630, is arranged to selectively extend or retract the scissor jack mechanism in the vertical direction. Actuator 630 may be connected to rod 640, which passes horizontally through and is mounted on support platform 411, or on a base or equivalent above it. Rod 640 may be formed as a worm gear. The lower end of first support arm 610 may be attached to actuator 630 via shaft 640. The lower end of first support arm 610 may have a hinge joint cooperating with worm gear 640. Worm gear 640 may be attached to the lower end portion of support arms 610, 620 via a connecting portion. The outer end of worm gear 640 may be supported on support platform 411. Rotation of actuator 630 in a first direction will move the lower ends of support arms 610, 620 toward each other, thereby moving support platform 411 and working platform 420 away from each other. Rotation of actuator 630 in the second opposite direction will move the lower ends of support arms 610 and 620 away from each other, thereby moving support platform 411 and work platform 420 toward each other. Therefore, work platform 420 can be selectively raised or lowered relative to support platform 411 using actuator 630. Actuator 630 can be formed by an electric motor, such as an electric motor for rotating worm gear 640. A pair of scissor jack mechanisms 600 can be used, i.e., one articulated jack 600 can be respectively provided on each side edge of support platform 411 and work platform 420. As an alternative to the worm gear, the actuator 630 of the scissor jack mechanism 600 can be a hydraulic cylinder-piston actuator.

[0109] For example, a cylinder-piston actuator may then extend between the support platform 411 and the upper portion of either support arm 610, 620. The scissor jack mechanism 600 may also include several layers of laterally extending support arms stacked on top of each other. As another alternative, a hydraulic cylinder-piston actuator may be arranged horizontally to selectively push or pull one end of the support arms 610, 620 along guide rails.

[0110] Generally, regarding actuation, gravity can be used to induce or assist contraction. Actuated contraction does not necessarily have to actually produce movement with the actuation device 434, 435; 434', 435'; 434”; 630, such as motor rotation, tower shortening, or the contraction movement of a scissor jack mechanism. This is because, for example, the transition from actuation device 434, 435; 434', 435'; 434”; 630 to a free oscillation mode or a braking mode can be utilized simply. For example, in Figure 12 and Figure 13 In one embodiment, motor 434 can be converted to free rotation, or generate a torque to brake the rotation caused by gravity, thereby controlling contraction. Similarly, for example in... Figure 14 In some embodiments, actuated contraction may include switching the hydraulic circuit to cause pressure release in chamber 439c, preferably in a controlled manner, to maintain the pressure for the hydraulic cylinder contraction caused by braking gravity, thereby controlling the contraction. Similarly, for example in... Figure 16 In one embodiment, actuated contraction may include an actuation unit 630 that can be converted to free rotation or generate a torque for braking the rotation caused by gravity, in order to control contraction.

[0111] about Figure 12-16 The alternative options should be understood to be based on Figure 14 The support structure 430 of the embodiment is used to implement the reference.

When implemented, it can be achieved by replacing one or more support structures 430” with one or more alternative support structures in discussion.

[0112] Generally, the positions of the support structures 430; 430'; 430”; 430”'; 430”” can be freely positioned to suit the layout, but are preferably located near the two opposite side edges of the support platform 411.

[0114] The support structure 430' includes an upright tower 431' that can be selectively actuated to extend or retract in a vertical direction. The upright tower 431' includes three elongated tower members 432, 433, and 437 that are movable relative to each other and oriented parallel to each other in a vertical direction.

[0115] The second tower component 433 is supported by a form-locking mechanism with the first tower component 432, and the third tower component 437 is supported by a form-locking mechanism with the second tower component 433. The form-locking mechanisms of the slender tower components 432, 433, and 437 are as follows: Figure 20 As shown.

[0116] Elongated tower components 432, 433, and 437 are supported against each other for movement along each other, such that the first tower component 432 guides the second tower component 433, and the second tower component 433 guides the third tower component 437. This is implemented such that the first tower component 432 and the second tower component 433 have interlocking profiles capable of movement along each other, and the second tower component 433 and the third tower component 437 have interlocking profiles capable of movement along each other.

[0117] Figures 17 to 20 Implementation, for example, refer to Figure 13 The described structure includes two flexible members 435 and wheels connected to tower frame members 432, 433, and 437. Specifically, in... Figures 17 to 20 In one embodiment, the actuating devices 434, 435 include a motor 434 arranged to rotate two drive wheels 436, a flexible member 435 passing around each drive wheel, and rotation of each wheel 436 arranged to move one flexible member 435. Each of the flexible members 435 is arranged as shown in reference... Figure 13 As shown in the figure, in this embodiment, the flexible member 435 is a toothed strip.

[0118] Already referred to Figures 1 to 20The mobile data center 1, its preferred features, and alternative solutions are described. Generally, the mobile equipment room 1 includes a support platform 411 for a hoist 14, the support platform 411 including one or more releasable mounting mechanisms 402 for releasably mounting the mobile equipment room 1 in the hoistway 2, and the hoist 14 mounted on the support platform 411; a working platform 420 above the support platform 411, the working platform 420 preferably forming the top of the mobile equipment room 1 and / or including handrails 421; and at least one support structure 430; 430'; 430”; 430”'; 430””, the working platform 420 being supported on the support platform 411 by the at least one support structure, wherein each support structure 430; 430'; 430”; 430”'; 430”” is selectively actuated to obtain a reaction force from the support platform 411 to extend vertically to raise the working platform (420) to a position higher than above the support platform 411, or to retract vertically to lower the working platform 420 toward the support platform 411. The mobile computer room 1 preferably also includes an operating interface 500, which is operable to control the actuation of at least one selectively actuated support structure.

The movable machine room 1 is installed in transport positions I and II in the shaft 2, which is vertically supported on a fixed structure, and the elevator car 4 is located in the shaft 2 below the movable machine room 1.

[0120] The above text presents several alternatives for support structures capable of selective actuation. As another alternative, a support structure capable of selective actuation can be implemented using a helical mechanism operated by an actuator. The actuator can be an electric motor, such as an electric motor. Racks, pinions, and worm gears can also be used in helical mechanisms.

[0121] Generally, preferably, the work platform 420 is located at least 1.5 meters, more preferably at least 1.8 meters, above the support platform 411, thereby providing a considerable space between them for work and / or safe loitering. This is always the preferred situation. Therefore, it is preferred that at least one support structure 430; 430'; 430”; 430”'; 430”” be in a retracted state, provided that at least one support structure 430; 430'; 430”; 430”'; 430”” can be selectively actuated to extend or retract.
