Installation platform for installing elevators during building construction

Abstract

An installation platform for installing a hoist during building construction. The installation platform includes two platforms (100, 200) and a support frame (300) including horizontal support beams (310, 320) and vertical support beams (330, 340) supporting the respective platforms. The installation platform has a width (W1) in a first horizontal direction (X) between guide rails and a depth (D1) in a second horizontal direction (Y) perpendicular to the first horizontal direction. The installation platform is movably guided on the guide rails via a guide device (160). At least one of the width and depth of the installation platform is adjustable to adjust the horizontal dimension of the installation platform according to the horizontal dimension of the hoistway.

Description

Technical Field

[0001] This invention relates to an installation platform and method for installing a lift during building construction. Background Technology

[0002] The construction of elevators, especially in high-rise buildings, can be completed partially along the height of the shaft. Guide rails and landing doors can be installed first at a first height within the shaft, then at a second height, and so on. When the elevator is constructed at the upper part of the shaft, it can be operated from the already installed lower part of the shaft during construction.

[0003] The installation platform can be used for the construction of the elevator above the hoist during construction, which is operated at the lower part of the shaft.

[0004] Existing installation platforms are constructed to meet the horizontal dimensions of a specific shaft. These platforms are used only during the construction of the elevator and are removed afterward. Summary of the Invention

[0005] The purpose of this invention is to provide an improved installation platform and method for installing elevators during building construction.

[0006] The mounting platform for installing a lift during building construction as defined in claim 1.

[0007] The method for installing a lift during building construction as defined in claim 13.

[0008] The adjustability of at least one of the width and depth of the mounting platform allows the installation platform on site to be adjusted to different shafts with different horizontal dimensions. The same mounting platform can be used in shafts with different distances between the guide rails and / or between the rear and front walls of the shaft.

[0009] An embodiment in which the width of the mounting platform can be adjusted along a first horizontal direction between the guide rails allows the mounting platform to be adjusted on-site to shafts with different distances between the guide rails.

[0010] An embodiment where the depth of the mounting platform can be adjusted along a second horizontal direction between the rear and front walls of the shaft allows the mounting platform to be adjusted on-site to fit shafts with different distances between the rear and front walls. This eliminates the wide gap between the front edge of the mounting platform and the platform itself.

[0011] An embodiment in which the width of the installation platform is adjustable in a first horizontal direction between the guide rails and the depth of the installation platform is adjustable in a second horizontal direction between the rear and front walls of the shaft allows the installation platform to be adjusted on-site to different shafts with different distances between the guide rails and to different shafts with different distances between the rear and front walls.

[0012] The adjustability of the installation platform's width and / or depth (i.e., the horizontal dimensions of the platform and support frame) allows for adaptation to different shafts on-site. Therefore, the installation platform becomes reusable, meaning it can be used virtually any shaft. When the installation platform is no longer needed at the initial location, it can be removed and transported to another construction site.

[0013] The adjustable mounting platform minimizes the risk of accidents when technicians enter and exit the installation platform. It also reduces the risk of objects falling off the platform.

[0014] Components of the installation platform can be manufactured in a factory outside the elevator installation site. These components can then be transported to the elevator installation location, where the platform can be assembled. Alternatively, the installation platform can be prefabricated and assembled into one or more transportable modules in a factory. These modules can then be transported to the construction site using conventional transportation methods. The installation platform can be raised into the shaft during the early stages of shaft and building construction. Its use can begin once the shaft has reached a height suitable for elevator installation.

[0015] The mounting platform can be used to install guide rails, shaft doors, and any other equipment that may be needed in the hoistway of the elevator.

[0016] The installation platform can be used for manual and / or automated lift installation. During the lift installation process, one or more mechanics can work on the platform. Alternatively, the platform can be equipped with one or more industrial robots that perform the lift installation. Of course, manual and automated installation can also be combined in any desired manner. Attached Figure Description

[0033] Figure 16 A cross-section of the fixed device in the locked position is shown. Detailed Implementation

[0034] Figure 1 A cross-sectional view of the mounting platform is shown. Figure 2 An isometric view of the mounting platform is shown.

[0035] The attached diagram illustrates the vertical direction Z, the first horizontal direction X, and the second horizontal direction Y. The first horizontal direction X is the direction between the guide rails 25. The second horizontal direction Y is perpendicular to the first horizontal direction X. The first horizontal direction X extends between the sidewalls in the shaft 20. The second horizontal direction Y extends between the rear and front walls in the shaft 20.

[0036] The figure also shows the width W1 of the mounting platform. Width W1 extends along a first horizontal direction X between the guide rails 25. The figure also shows the depth D1 of the mounting platform. Depth D1 extends in a second horizontal direction Y.

[0037] The mounting platform can be movably supported on guide rail 25, which is supported by bracket 26 on the wall 21 of the shaft 20. Guide rail 25 can be formed of guide rail elements. The opposite ends of two consecutive guide rail elements can be connected to each other using guide rail fastening components. These fastening components can be formed of connecting elements, such as fishplates 27. Guide rail elements can have a certain length, for example, 5 meters. Guide rail elements can be connected to the wall 21 of the shaft 20 using guide rail fastening components such as bracket 26. Brackets 26 can be located near both ends of the guide rail elements. Figure 1 Only the bottom of shaft 20 is shown in the image.

[0038] The mounting platform may include a first platform 100, a second platform 200, and a support frame 300 supporting the platforms 100 and 200. The second platform 200 may be positioned above the first platform 100 in the vertical direction Z. Each platform 100 and 200 may include a base 110 and 210 and armrest structures 400 and 500 (in... Figure 2 (As shown in the diagram). The first platform 100 can form a lower platform and the second platform 200 can form an upper platform. The installation of the elevator's guide rails and other equipment can be completed manually and / or automatically from the two platforms 100 and 200 in the installation platform.

[0039] The installation platform can be lifted using a hoisting device 610. The hoisting device 610 can be supported on the upper platform 200. A lifting rope 630 can pass over a rope pulley 640, which is supported at a support point P1 in the shaft 20 at a distance Z10 above the installation platform. The other end of the lifting rope 630 can be supported on a fixing member 620, which is also supported on the upper platform 200. The hoisting device can be a Tirac... TM A hoisting device 610 is provided, in which a lifting rope 630 extends between traction sheaves. Rotation of the traction sheaves in the hoisting device 610 in a first direction moves the hoisting device 610 in that direction, and rotation of the traction sheaves in the hoisting device 610 in a second opposite direction moves the hoisting device 610 in that second opposite direction. When the hoisting device 610 is supported on an installation platform, the installation platform moves upward and downward together with the hoisting device 610. The installation platform is suspended from the hoisting device via rope pulleys 640 located at support points P1 in the shaft 20.

[0040] The lifting device 610 shown in the figure forms an example of a lifting device that can be used in this invention. In this invention, a lifting device suspended from a support point P1 in the shaft 20 above the installation platform can also be used. The installation platform will then be directly suspended from the lifting device 610 using the lifting rope 630, i.e., a separate rope pulley 640 is not required.

[0041] In both cases, the installation platform is suspended from the lifting device 610 by a lifting rope 630, which is either directly transferred from the lifting device 610 to the installation platform or via a rope pulley 640. If necessary, several rope pulleys 640 can also be used. Then, using the lifting rope 630, which is transferred directly from the lifting device 610 to the installation platform or via at least one rope pulley 640, the installation platform will be suspended from the lifting device 610. Several parallel lifting devices 610 can also be used to lift the installation platform.

[0042] The support frame 300 may include horizontal support beams 310 and 320 supporting corresponding platform 100, 200, and vertical support beams 330 and 340 extending between the horizontal support beams 310 and 320. The support frame 300 may include a first horizontal support beam 310 supporting the first platform 100 and a second horizontal support beam 320 supporting the second platform 200. The vertical support beams 330 and 340 may extend vertically between the respective outer ends of the horizontal support beams 310 and 320. The support frame 300 may have a generally rectangular shape. The support beams 310, 320, 330, and 340 in the support frame 300 may have a generally U-shaped cross-section. The vertical support beams 330 and 340 may be positioned such that the U-shape opens outward toward the guide rail 25.

[0043] The first horizontal support beam 310 and the second horizontal support beam 320 in the support frame 300 can extend along a first horizontal direction X. The second horizontal support beam 320 can be positioned at a vertical distance Z1 above the first horizontal support beam 310. Therefore, the second platform 200 can be positioned at a vertical distance Z1 above the first platform 100.

[0044] The support frame 300 may have a similar structure to the slings of an elevator car.

[0045] The mounting platform may also include a guide member 160 for movably guiding the mounting platform on the guide rail 25. The guide member 160 may be supported on a support frame 300, such as on vertical support beams 330, 340 of the support frame 300. The guide member 160 may be positioned within and / or outside the vertical support beams 330, 340 in the support frame 300. The mounting platform may move along the guide rail 25 in the vertical direction Z together with the lifting device 610. The guide member 160 guides the mounting platform on the guide rail 25, making movement along the guide rail 25 possible only in the vertical direction Z. During the vertical movement of the mounting platform, the guide device 160 keeps the mounting platform stable in the horizontal plane.

[0046] The guide member 160 can be formed of a roller assembly, whereby the roller rolls on the guide surface of the guide rail 25. This roller assembly can correspond to a roller assembly used in an elevator car to guide the elevator car on a guide rail. Alternatively, the guide member 160 can be formed of a sliding device, whereby the sliding device slides on the guide surface of the guide rail 25. This sliding device can correspond to a sliding device used in an elevator car to guide the elevator car on a guide rail.

[0047] The mounting platform may also include a clamping device 170 for securing the mounting platform to the guide rail 25 and / or the guide rail fixing member. The clamping device 170 may be formed by a safety mechanism to prevent accidental falls of the mounting platform. The clamping device 170 may be positioned on opposite vertical sides of the mounting platform. The clamping device 170 may be supported on the mounting platform and act on the guide rail 25 and / or the guide rail fixing member. The guide rail fixing member may be formed by a fishplate 27 connecting the ends of the guide rail elements together and / or a bracket 26 connecting the guide rail 25 to the wall 21 of the hoistway 20. The clamping device 170 can clamp the guide rail 25 and / or the fishplate 27 and / or the bracket 26. The clamping device 170 can secure the mounting platform to the guide rail 25 in the hoistway 20. Some examples of the clamping device 170 will be combined. Figure 11 and 12 To explain in more detail.

[0048] The synchronous shaft 175 can connect the clamping devices 170 on opposite sides of the support frame 300 together.

[0049] The first countertop 100 may include a first base 110 and a first handrail structure 400 supported on the first base 110. The second countertop 200 may include a second base 210 and a second handrail structure 500 supported on the second base 210. The bases 110 and 210 of each countertop 100, 200 may be formed by horizontal support beams. A floor may be formed on the horizontal support beams. The first base 110 and the second base 210 may be substantially rectangular.

[0050] The bottom 110 of the first platform 100 may include two first horizontal support beams 111, 112 extending along a first horizontal direction Y. The two first horizontal support beams 111, 112 may be positioned at opposite outer edges of the bottom 110 of the platform 100. The two first horizontal support beams 111, 112 may be supported on corresponding vertical support beams 330, 340 of the support frame 300. The two first horizontal support beams 111, 112 may extend on the bottom surface of the first horizontal support beam 310 of the support frame 300 and on the inner surface of the corresponding vertical support beams 330, 340 of the support frame 300.

[0051] The bottom 110 of the first countertop 100 may also include second horizontal support beams 113, 114 extending in the first horizontal direction X. The two second horizontal support beams 113, 114 may be positioned at opposite outer edges of the bottom 110 of the first countertop 100. The two second horizontal support beams 113, 114 may be supported on the outer ends of the first horizontal support beams 111, 112. The two second horizontal support beams 113, 114 of the support frame 300 and the first horizontal support beam 310 form support for the floor 115 of the first countertop 100. The first horizontal support beam 310 of the support frame 300 is substantially located at the center of the floor 115. The floor 115 in the first countertop 100 may be formed by a grid structure. The grid structure may include several grids overlapping each other. The dimensions of the floor 115 can therefore be adjusted in the first horizontal direction X and / or the second horizontal direction Y by adjusting the overlap of the grid members.

[0052] The first handrail structure 400 in the first platform 100 may include vertical support beams 410 and horizontal support beams 420 forming a cage. The vertical support beams 410 extend upwards from the bottom 110 of the first platform 100. Vertical support beams 410 may be present at the corners of the bottom 110 of the first platform 100 and on the sides of the bottom 110 of the first platform 100. A passageway may be arranged at the front of the first platform 100 within the cage. Maintenance personnel can enter the first platform 100 through the passageway via a landing opening and exit the first platform 100 through the passageway and the landing opening in the hoistway. The first handrail structure 400 may also include horizontal support beams 420 extending between the vertical support beams 410. A first set of horizontal support beams 420 may be located at the upper end of the vertical support beams 410, and a second set of horizontal support beams 420 may be located at the midpoint of the height of the vertical support beams 410. The first handrail structure 400 may form a safety device on the first platform 100.

[0053] The handrail structure 400 may also include horizontal support plates 116 surrounding the lower edge of the vertical support beam 410. These horizontal support plates 116 may support the vertical support beam 410 relative to each other. These horizontal support plates 116 may also support the vertical support beam 410 relative to the bottom 110 of the first platform 100.

[0054] The structure of the second tabletop 200 can be the same as that of the first tabletop 100.

[0055] The second platform 200 may include two first horizontal support beams 211 and 212 extending along a second horizontal direction Y at the opposite outer edges of the bottom 210 of the second platform 200. The second platform 200 may also include two second horizontal support beams 213 and 214 extending along a first direction X at the opposite outer edges of the bottom 210 of the second platform 200.

[0056] The floor 215 in the second countertop 200 can be formed by a grid structure in the same way as the floor 115 in the first countertop 200. The grid structure may include several grid blocks that overlap each other. The size of the floor 215 can therefore be adjusted in the first direction X and / or the second direction Y by adjusting the overlap of the grid members.

[0057] The second handrail structure 500 of the second platform 200 can be the same as the first handrail structure 400 of the first platform 100. Therefore, the second handrail structure may include a vertical support beam 510 and a horizontal support beam 520 forming the car.

[0058] At the bottom end of the vertical support beam 510 of the second handrail structure 500, there may also be a horizontal support plate 216 surrounding the bottom 210 of the second platform 200. These horizontal support plates 216 can support the vertical support beam 510 relative to each other and relative to the bottom 210 of the second platform 200.

[0059] The lifting device 610 and the fixing component 620 are also included. Figure 2 As shown in the image.

[0060] Figure 3 An enlarged view of part of the mounting platform is shown.

[0061] Each horizontal support beam in the bottoms 110 and 210 of the tabletops 100 and 200 can be formed by two separate beams arranged to form a telescopic structure. Each of the two separate beams can be provided with an inclined longitudinal opening O1. The two separate beams forming the telescopic structure can be connected to each other by bolts passing through the inclined longitudinal openings O1. Therefore, the horizontal support beams 113, 114, 213, and 214 in the tabletops 100 and 200 extending in the first horizontal direction X can extend in the first horizontal direction X. Therefore, the horizontal support beams 111, 112, 211, and 212 in the tabletops 100 and 200 extending in the second horizontal direction Y can extend in the second horizontal direction Y.

[0062] The horizontal support beams 310 and 320 in the support frame 300 can be formed in the same way by two separate beams arranged to form a telescopic structure and providing an inclined longitudinal opening O1. Therefore, the lengths of the horizontal support beams 310 and 320 in the support frame 300 can be adjusted in the first horizontal direction X.

[0063] Therefore, the length of the telescopic structure can be changed by opening and removing bolts, changing the position of two separate beams that are opposite each other, and inserting and fixing bolts.

[0064] This is one possibility for implementing a telescopic structure in the horizontal support beams 111, 112, 113, 114, 211, 212, 213, 214 at the bottom of the tabletops 100 and 200, and in the horizontal support beams 310 and 320 in the support frame 300.

[0065] The first platform 100, the second platform 200, and the support frame 300 can be configured such that only the horizontal support beams 113, 114, 213, 214 extending along the first horizontal direction X in the platforms 100 and 200, and the horizontal support beams 310 and 320 in the support frame 300, are adjustable. This means that only the width W1 of the mounting platform is adjustable. Therefore, the mounting platform can be adapted to different shafts 20 with different distances between the guide rails 25 in the first direction X.

[0066] As a second option, the first platform 100 and the second platform 200 can be configured such that only the horizontal support beams 111, 112, 211, and 212 extending in the second horizontal direction Y of the platforms 100 and 200 are adjustable. This means that only the depth D1 of the mounting platform is adjustable. Therefore, the mounting platform can be applied to different hoists 20 with different distances between the rear and front walls of the hoistway 20 in the second horizontal direction Y. The distance between the front edge of the platforms 100 and 200 and the platform can thus be kept to a minimum to eliminate accidents. The distance between the rear edge of the platforms 100 and 200 and the rear wall in the hoistway 20 does not need to be adjusted. Handrails at the rear edges of the platforms 100 and 200 prevent mechanics from falling.

[0067] As a third option, the first platform 100 and the second platform 200 can be configured such that the horizontal support beams 111, 112, 113, 114, 211, 212, 213, and 214 in the platforms 100 and 200 extending in the first horizontal direction X and the second horizontal direction Y are adjustable. This means that the mounting platform is adjustable in the width direction W1 and the depth direction D1. Therefore, the mounting platform can be applied to different shafts 20 that have different distances between the guide rails 25 in the first horizontal direction X and different distances from the rear wall to the front wall of the shaft 20 in the second horizontal direction.

[0068] Figure 4 A cross-sectional view of the guide rail is shown.

[0069] The cross-section of the guide rail 25 may have a general inverted T-shape. The guide rail 25 may include a bottom 25A, from which it can be connected to the wall structure in the shaft 20 via a bracket 26. The guide rail 25 may also include a guide portion 25B extending vertically outward from the bottom 25A. The guide portion 25B may extend outward from the center of the bottom 25A. The guide portion 25A may include a front guide surface 25B1 on the outer edge of the guide portion 25B and two opposing side guide surfaces 25B2, 25B3 on opposite side surfaces of the guide portion 25B. The guide component 160 of the mounting platform may roll or slide on the guide surfaces 25B1, 25B2, 25B3 of the guide rail 25.

[0070] Figure 5 A portion of the handrail of the mounting platform in its retracted state is shown. Figure 6 A portion of the handrail of the mounting platform in its extended state is shown.

[0071] The horizontal support beam 420 extending in the first direction X is Figure 5 It is shown in a contracted state and in Figure 6The horizontal support beam 420 is shown in an extended state. Therefore, the horizontal support beam 420 has a telescopic structure. The horizontal support beam 420 can be formed by two separate beams 421 and 422 that are movable relative to each other. Beams 421 and 422 can have rectangular cross-sections. The cross-section of the first beam 421 can be smaller than the cross-section of the second beam 422. Therefore, the first beam 421 can slide within the second beam 422. Thus, the length of the support beam 420 can be changed by altering the length of the portion of the first beam 421 within the second beam 422. The first beam 421 in... Figure 5 The middle section was completely pushed into the second beam 422, while the first beam 421 was... Figure 6 The middle section was completely pulled out from the second beam 422.

[0072] The horizontal support beam 420 extending along the second direction Y can have the same structure as the horizontal beam 420 extending along the first direction X.

[0073] Figure 7 An isometric view of the extendable beam used for mounting the platform is shown. Figure 8 A side view of the extendable beam used for mounting the platform is shown.

[0074] Figure 7 and 8 The extendable support beam 113 shown is formed Figure 3 The alternative form of the extendable support beam 113 shown is illustrated. The telescopic structure differs in these two embodiments.

[0075] The support beam 113 may include a central portion 113A and two opposing ends 113B, 113C. The cross-section of the support beam 113 may be generally rectangular. The cross-sections of the ends 113B, 113C may be smaller, allowing them to slide within the central portion 113A. The opposing edges of the ends 113B, 113C may include grooves that receive corresponding protrusions in the respective edges of the central portion 113A. A locking device 113D may be disposed in the opposing ends of the central portion 113A. The locking device 113D can lock the corresponding ends 113B, 113C relative to the central portion 113A. Rotating the locking device 113D counterclockwise unlocks the lock between the central portion 113A and the corresponding ends 113B, 113C. Thus, the corresponding ends 113B, 113C can move relative to the central portion 113A to adjust the length of the support beam 113. Rotating the locking device 113D clockwise locks the corresponding ends to the central portion 113A. The locking device 113A can be formed by bolts and nuts.

[0076] Figure 9 A horizontal cross-sectional view of the platform surface in the mounting platform is shown. Figure 10 A vertical cross-sectional view of the mounting platform is shown.

[0077] The mounting platform can be movably guided by guide components 160 on guide rail 25. The bottom of the second platform 200 may provide a first fixing device 231 for the lifting device 610 and a second fixing device 232 for the fixing member 620. The bottom 110, 210 of each platform 100, 200 may also provide an opening 221 extending in a second horizontal direction Y. A hoistway 222 extends through the opening 221 in the first horizontal direction X. The hoistway 222 may be positioned at the center of the platform 200. When the lifting device 610 is used to lift the car located below the mounting platform during the jump phase, the lifting rope 630 of the lifting device 610 may pass downward through the opening 221. If the fixing member of the lifting rope 630 breaks, the hoistway 222 prevents the lifting rope 630 from falling through the opening 221.

[0078] The floor 115, 215 in each countertop 100, 200 of the installation platform can be formed from a sheet and grid panels on the sheet. The floor can be formed from several overlapping sheet pieces and grid panels. The sheet pieces and grid panels can be substantially rectangular in shape. The sheet can be made of polycarbonate or waterproof plywood. The grid panels can be made of glass-reinforced plastic or some other grid material with corresponding properties. These sheet pieces prevent small objects from falling through the floor of the countertop 100, 200. The grid panels prevent slippage.

[0079] The mounting platform may also be provided with rail compartments 710. An embodiment shows four rail compartments 710, but any number of rail compartments 710 can be supported on the mounting platform. The rail compartments 710 can be supported on a side edge extending along a first horizontal direction X of the mounting platform.

[0080] The guide rail compartments 710 can be connected to the first tabletop 100 and the second tabletop 200. The guide rail compartments 710 can also support the mounting platform in the vertical direction, thus increasing the rigidity of the mounting platform.

[0081] Figure 8 The diagram also shows alternative locations for the guide rail compartment 710. In cases where there is insufficient space in the hoistway 20, the guide rail compartment 710 can be positioned within the perimeter of the mounting platform.

[0082] Figure 11 A cross-sectional view of an example clamping device is shown.

[0083] The installation platform is typically raised and lowered using a hoisting device 610. A safety brake can be used as a safety device in the installation platform. The safety brake allows the installation platform to move upwards but prevents it from falling downwards in an uncontrolled manner. When the installation platform falls uncontrollably, the safety brake clamps onto the guide rails. Any safety brake of the prior art can be used in this connection.

[0084] The safety brake thus forms a clamping device. As an alternative to or in addition to the safety brake, the mounting platform can be provided with other types of clamping devices.

[0085] Figure 11 The clamping device 170 shown forms an example of a clamping device that can be used as an alternative to or as an addition to a safety brake in conjunction with a mounting platform.

[0086] The clamping device 170 may be formed by a braking device 180. The braking device 180 may include a frame 181 having a slit for the guide rail 25 and two wedge-shaped brake shoes 182 positioned on opposite sides of the guide rail 25. The brake shoes 182 may be movably supported from the wedge-shaped surface by rollers 183 on the frame 181. A spring 184 may be positioned between a first end of the brake shoe 182 and the frame 181. The second opposite end of the brake shoe 182 may be supported on a slider 185 acting in a cylinder 186.

[0087] The hydraulic power unit 189 can provide power to the braking device 180. The hydraulic pump can pump oil from the reservoir to the cylinder 186 to move the sliding member 185 in the cylinder 186.

[0088] Supplying pressurized fluid to the plunger 185 in cylinder 186 will overcome the force of spring 184 and press the brake shoe 182 downwards in the figure. The brake shoe 182 is thus removed from the guide surface of guide rail 25. Therefore, the mounting platform can move freely on guide rail 25.

[0089] The force generated by the spring 184 acting on the second end of the brake shoe 182 causes pressurized fluid to be drawn from the cylinder 186, allowing the brake shoe 182 to move upwards as shown in the figure. The brake shoe 182 thus moves into contact with the guide surface of the guide rail 25. Therefore, the mounting platform is locked onto the guide rail 25.

[0090] Hydraulic unit 189 may be provided solely for braking device 180. Alternatively, all equipment requiring hydraulic power on the mounting platform may share a common main hydraulic unit on the mounting platform. Hydraulic valves may be used to connect different pieces of equipment to the shared main hydraulic power unit.

[0091] Alternatively, the braking device 180 can be electromechanically operated. The electromechanical device can be used to overcome the force of the spring 184 to press the brake shoe 182. Deactivation of the electromechanical device will activate the brake shoe 182 to abut against the guide rail 25.

[0092] Figure 12 An isometric view of another example of a clamping device is shown.

[0093] Figure 12The clamping device shown forms another example of a clamping device that can be used as an alternative to or as an addition to a safety brake in conjunction with a mounting platform.

[0094] The second clamping device 170 may be formed by the anchoring device 190. The anchoring component 190 may include a frame 191 supported on the support frame 300 and two jaws 192 positioned on opposite sides of the guide rail 25. The jaws 192 may be supported on the frame 191 via a first hinge joint J1. An actuator may be connected to the jaws 192 on opposite sides of the first hinge joint J1 (not shown). The actuator may cause the jaws 192 to rotate about the first hinge joint J1 between a locked position and an unlocked position. In the locked position, the jaws 192 rest on the upper support surface 27A of the fishtail plate 27. In the unlocked position, the jaws rotate clockwise, thereby disengaging from contact with the fishtail plate 27.

[0095] The actuator can be formed by a hydraulic cylinder or electromechanical equipment. The jaws 192 can be operated by an electric motor or one or more electromechanical devices.

[0096] The mounting platform is supported on the fishplate 27 in the locked position of the anchoring device 190. The support on the fishplate 27 eliminates downward movement of the mounting platform. In the unlocked position of the anchoring device 190, the mounting platform moves freely on the guide rail 25.

[0097] Fishplate 27 is typically located at the junction between two consecutive guide rail elements. Additional fishplate 27 can be positioned along the length of the guide rail element. The guide rail element may be provided with an intermediate fishplate 27, which is attached to the guide rail element before installation. The fishplate 27 can, for example, be positioned in the middle of a 5m long guide rail element. The intermediate fishplate 27 can remain permanently on the guide rail after installation. Alternatively, the intermediate fishplate can be removed when installation proceeds upwards.

[0098] The connecting plate 27 may be wider than the guide rail 25, such that the upper surface of the connecting plate 27 forms an upper support surface 27A for the jaws 192 on each side of the guide rail 25. Therefore, the structure of the fishtail plate 27 can be used as a support point for the jaws 192 in the anchoring member 190.

[0099] Fishplate 27 is an example of a connecting element that can be used to connect the ends of continuous guide rail elements.

[0100] A similar anchoring component 190 can be used to lock the mounting platform to a bracket 26 that attaches the guide rail 25 to the wall 21 in the wellbore 20. Jaws 192 can then interact with the bracket 26.

[0101] Figure 13 An isometric view of the mounting platform with a guide rail compartment is shown.

[0102] An installation platform with two surfaces 100 and 200 can provide a guide rail compartment 710. The guide rail elements 25 can therefore be stored on the installation platform for specific needs. The guide rail compartment 710 can be refilled while the guide rails are being installed in the shaft. This can be done, for example, via a stair platform in the shaft or via a hoisting device connected to the installation platform.

[0103] Each countertop 100 or 200 is provided with a handrail structure 400 or 500.

[0104] The lifting device 610 and the fixing element 620 are also shown in the figure.

[0105] Figure 14 An isometric view of the mounting device for the guide rail is shown in its non-operating position. Figure 15 The fixed device in the operating position is shown, and Figure 16 A cross-section of the fixed device in the locked position is shown.

[0106] The fixing device 800 may include a frame 820, a carrier 810, clamping devices 830 and 840, and a locking device 817.

[0107] The frame 820 is pivotally supported on the carrier 810 by the frame 816.

[0108] Clamping devices 830 and 840 are pivotally supported on the first end of frame 820. Fixing members 830 and 840 may have a closed position and an open position. In the closed position, fixing members 830 and 840 surround the guide rail element, and in the open position, fixing members 830 and 840 are disconnected from the guide rail element.

[0109] The locking device 817 prevents the frame 820 of the fixing device 800 from rotating upward about the pivot point 816 above the horizontal plane. On the other hand, the locking device 817 allows the frame 820 to rotate downward about the pivot point 816. Therefore, the guide rail element moves freely upward within the fixing members 830 and 840, but when the guide rail element moves downward, it is prevented from falling as the frame 820 rotates downward about the pivot point 816, so that the guide rail element is locked against the edge of the fixing members 830 and 840.

[0110] The carrier 810 may be movable. The carrier 810 may include a frame 811 and rollers 815 supported on the frame 811. The carrier 810 may be supported by the rollers 815 on a horizontal support beam 117 extending in a second direction Y. A pair of support arms 812 may be attached to the frame 811 of the carrier 810. The pair of support arms 811 may extend upward from the frame 811 of the carrier 810. Each of the pair of support arms 812 may include two holes O1, O2 passing through the support arm 812. The two holes O1, O2 may extend horizontally through the support arm 812. The rollers 815 of the carrier 810 may be supported on support surfaces 117A, 117B, 117C in the horizontal support beam 117. The carrier 810 may include four rollers 815.

[0111] The frame 820 of the fixing device 800 may include a first support plate 822 and a second support plate 823. One end of a support arm 821 may be connected to the first support plate 822. The support arm 821 may extend downward from the first support plate 822. The first support plate 823 may be connected to the bottom of the second support plate 823 using two bolts 824 and 825. The bolts 824 and 825 may pass through elliptical holes 823A and 823B in the second support plate 823. The support arm 821 may extend between the pair of support arms 812 of the carrier 810. The support arm 821 may include a hole O3 passing through the support arm 821. The hole O3 may extend horizontally through the support arm 821.

[0112] The support arm 821 of the frame 820 of the fixed device 800 can be connected to the support arm 812 of the carrier 810 by means of a horizontal pin 816 passing through the support arm 812 of the carrier 810 and the first hole O1 in the support arm 821 of the frame 820 of the fixed device 800. The pin 816 forms a pivot point of the frame 820 of the fixed device 800 relative to the carrier 810.

[0113] The fixing components 830 and 840 of the fixing device 800 can be formed by two jaws 830 and 840. Each jaw 830 and 840 can be supported on the first end of the frame 820, i.e., the first end of the second support plate 823, via a corresponding hinge joint J1 and J2. Each jaw 830 and 840 can have a first end 831 and 841 on one side of the hinge joint J2 and J3, and a second end 832 and 842 on the opposite side of the hinge joint J2 and J3. The second end 832 and 842 of each jaw 830 and 840 can include holes 833 and 843 passing through the jaw 830 and 840.

[0114] The fixing device 800 may also include a locking pin 850. The locking pin 850 may be formed by a separate pin that can lock the clamps 830 and 840 together in the closed position. The two clamps 830 and 840 can slide on each other such that when the clamps 830 and 840 are in the closed position, the holes 833 and 843 in the second ends 832 and 842 of the clamps 830 and 840 overlap. The locking pin 850 can then be pushed through the holes 833 and 843 in the second ends 832 and 842 of the clamp jaws 830 and 840, locking the jaws 830 and 840 in the closed position. In the figure, the second end 832 of the first clamp 830 slides on the second end 842 of the second clamp 840. When the clamps 830 and 840 open and close, the second ends 832 and 842 of the clamps 830 and 840 move in the overlapping plane. When clamps 830 and 840 open and close, the first ends 831 and 841 of clamps 830 and 840 move in the common plane.

[0115] On the other hand, the locking pin 850 can be spring-loaded into the hole 833 of the first clamp 830. Then, when the jaws 830 and 840 are closed, the locking pin 850 will be lifted against the spring force, allowing the holes 833 and 843 in the second ends 832 and 842 to overlap. The locking pin 850 can then be released, causing the spring to push the locking pin 850 into the second hole 843. The jaws 830 and 840 will then be locked in the closed position.

[0116] Clamp jaws 830, 840 Figure 14 The middle is in the open position, in Figure 15 and 16 The clamping device 800 is in the closed position. The clamping jaws 830 and 840 are in the closed position around the guide rail 25. The first ends 831 and 841 of the clamping jaws 830 and 840 are located after the bottom 25A of the guide rail 25, and the guide portion 25B of the guide rail 25 is located in the slot 825 of the frame 820, i.e., in the second frame 823 of the clamping device 800. When the clamping jaws 830 and 840 of the clamping device 800 are closed and the clamping device 800 is in the horizontal position, there is a gap between the guide rail 25 and the clamping device 800. Therefore, the guide rail 25 can move vertically upward relative to the clamping device 800.

[0117] The locking device 817 can be formed by the second pin 817. For example... Figure 15As shown, in the operating position of the fixed device 800, the second pin 817 can be pushed through the second hole O2 in the support arm 812 of the bracket 810. When the guide rail element 25 moves upward, the second pin 817 prevents the fixed device 800, i.e., the frame 820 of the fixed device, from rising above the horizontal position. However, when the guide rail element 25 moves downward, the fixed device 800 can rotate downward about the pivot point formed by the first pin 816. When the fixed device 800 is in the operating position... Figure 16 When rotated downwards, the guide rail element 25 is locked by the fixing device 800. The bottom surface of the bottom portion 25A of the guide rail element 25 is pressed against the edges of the first ends 831, 841 of the jaws 830, 840, and the outer end surface 25B1 of the guide portion 25B of the guide rail element 25 is pressed against the bottom of the slot 825 of the frame 820 of the fixing device 800. Therefore, the fixing device 800 will prevent the guide rail element 25 from falling accidentally.

[0118] The accompanying drawings illustrate advantageous embodiments of the mounting platform of the present invention. However, the invention is not limited to these embodiments. The support frame 300 may be formed, for example, by two or more parallel slings instead of a single sling. The arrangement and number of support beams in the platform may vary, and so on.

[0119] The installation of guide rail 25 can be completed manually and / or automatically from the installation platform. Mechanics and / or robots can work on the installation platform.

[0120] In addition to installing guide rails, the installation platform can also be used for the installation of shaft doors and any equipment that may be needed in the shaft of the elevator.

[0121] The use of this invention is not limited to the installation of any particular type of elevator. This invention can be used for the installation of any type of elevator, including elevators lacking a machine room and / or counterweight. The counterweight can be positioned on the rear wall of the shaft, on any one side wall of the shaft, or on both side walls of the shaft. The hoisting device can be located anywhere within the shaft.

[0122] It will be apparent to those skilled in the art that, with advancements in technology, the inventive concept can be realized in various ways. The present invention and its embodiments are not limited to the examples described above, but can be varied within the scope of the claims.
