Elevators and elevator installation methods

Abstract

In an elevator, the car equipment includes a car and an emergency stop device installed in the car. The starting device includes a starting device body and a starting device rope. The starting device body is positioned higher than the emergency stop device within the hoistway, and the starting device rope is connected to the starting device body. The starting device body has a braking unit and a winding unit for winding the starting device rope. The starting device rope is connected to the emergency stop device in a state where it is released from the winding unit against the winding force of the winding unit. When the car equipment moves downwards, if an abnormal car travel occurs due to excessive speed or acceleration, the braking unit applies a working braking force to the starting device rope, causing the emergency stop device to activate.

Description

Technical Field

[0001] This disclosure relates to an elevator equipped with an emergency stop device in the car and a method for installing the elevator. Background Technology

[0002] Previously, an elevator was proposed that, in the event of a breakage of the main rope suspending the car, activates an emergency stop device independent of the speed governor. Additionally, a previously known elevator installation method involves, for installing an elevator without a speed governor, allowing a steel wire rope to hang from the upper part of the shaft, and moving the car frame vertically along the steel wire rope.

[0003] In this conventional elevator installation method, a winch mounted on the car frame winds a steel wire rope. A work platform is installed on the car frame. The work platform and car frame move vertically by the winch winding and feeding the steel wire rope. This allows workers riding on the work platform to perform work within the shaft. When the steel wire rope breaks, the winch shifts relative to the car frame due to the spring force. This triggers an emergency stop device mounted on the car frame, stopping the car frame (see, for example, Patent Document 1).

[0006] Patent Document 1: Japanese Patent Application Publication No. 2000-118907 Summary of the Invention

[0007] The problem that the invention aims to solve

[0008] However, the conventional elevator installation method shown in Patent Document 1 involves operations such as lowering the wire rope from the top of the shaft, installing the work platform onto the car frame, and winding the wire rope around the winch. Therefore, it places a burden on the elevator installation work.

[0009] This disclosure was made to solve the aforementioned problems, and its purpose is to provide an elevator and an elevator installation method that can reduce the burden of installation work.

[0010] Methods for solving problems

[0011] The elevator disclosed herein includes: a car device having a car and an emergency stop device disposed in the car, the car device being movable vertically within a hoistway; and a starting device having a starting device body and a starting device rope, the starting device body being disposed within the hoistway at a position higher than the emergency stop device, the starting device rope being connected to the starting device body, the starting device body having a braking part and a winding part for winding the starting device rope, the starting device rope being connected to the emergency stop device in a state where it is released from the winding part against the winding force of the winding part, and when the car device moves downward, if a car travel abnormality occurs where the speed or acceleration of the car device becomes excessive, the braking part applies a working braking force to the starting device rope to activate the emergency stop device.

[0012] Furthermore, the elevator installation method disclosed herein includes: a lifting body installation step, in which a car device is installed in the hoistway in a manner capable of moving vertically, the car device having a car and an emergency stop device installed in the car; a main body temporary installation step, in which a starting device is temporarily installed in the hoistway, the starting device having a starting device body and a starting device rope connected to the starting device body; a connection step, in which the starting device rope is connected to the emergency stop device; and a car scaffolding step, in which, after the lifting body installation step, the main body temporary installation step, and the connection step, the car device is used as scaffolding. The operation within the hoistway; and the removal process, after the car scaffolding process, the starting device is removed. The starting device body has a braking part and a winding part for winding the starting device rope. The starting device rope is sent out from the winding part by overcoming the winding force of the winding part. In the temporary setting process of the main body, the starting device body is temporarily set at a position higher than the emergency stop device. In the car scaffolding process, if a car travel abnormality occurs when the car equipment moves downward and the speed or acceleration of the car equipment becomes too large, the braking part applies a working braking force to the starting device rope to activate the emergency stop device.

[0025] The embodiments will now be described with reference to the accompanying drawings.

[0026] Implementation method 1.

[0027] Figure 1 This is a side view showing an elevator installed using the elevator installation method of Embodiment 1. In the figure, a machine room 2 is provided above the hoistway 1. The machine room 2 is equipped with a traction machine 3, a deflector sheave 4, a control device 5, and a safety monitoring device 6.

[0028] The traction machine 3 has a traction machine body 7 and a drive sheave 8. The drive sheave 8 is disposed on the traction machine body 7. The traction machine body 7 has a traction machine motor and a traction machine brake. The traction machine motor generates a driving force that rotates the drive sheave 8. The traction machine brake keeps the drive sheave 8 stationary. In addition, the traction machine brake brakes the rotation of the drive sheave 8.

[0029] A suspension body 9 is wound around the drive pulley 8 and the deflector pulley 4. Multiple ropes or multiple belts are used as the suspension body 9.

[0030] Within the hoistway 1, the car assembly 10 and the counterweight 11 are configured to move vertically. The car assembly 10 is connected to the first end of the suspension body 9. The counterweight 11 is connected to the second end of the suspension body 9. The car assembly 10 and the counterweight 11 are suspended within the hoistway 1 by the suspension body 9. By rotating the drive sheave 8, the car assembly 10 and the counterweight 11 move vertically within the hoistway 1. That is, the traction machine 3 is the drive device that moves the car assembly 10 and the counterweight 11 vertically.

[0031] The car equipment 10 includes a car 12 and an emergency stop device 13. The car 12 is provided with a car entrance / exit 121. The car entrance / exit 121 is opened and closed by a pair of car doors 122.

[0032] Each floor of the building has a landing entrance / exit 14. The hoistway 1 opens to the landing at each floor through the landing entrance / exit 14. Each landing entrance / exit 14 is opened and closed by a pair of landing doors 15. At the floor where the car equipment 10 stops, the car entrance / exit 121 and the landing entrance / exit 14 are opened and closed by the linkage between the pair of landing doors 15 and the pair of car doors 122.

[0033] Control device 5 controls traction machine 3 to move car equipment 10 and counterweight 11 vertically at a set speed. Excess speed and excessive acceleration are preset in safety monitoring device 6. Safety monitoring device 6 monitors whether the speed of car equipment 10 reaches an excessive speed. That is, safety monitoring device 6 monitors whether an abnormality occurs where the speed of car equipment 10 becomes excessive, i.e., whether a car travel abnormality occurs based on excessive speed. Additionally, safety monitoring device 6 monitors whether the acceleration of car equipment 10 reaches an excessive acceleration. That is, safety monitoring device 6 monitors whether an abnormality occurs where the acceleration of car equipment 10 becomes excessive, i.e., whether a car travel abnormality occurs based on excessive acceleration. The functions of control device 5 and safety monitoring device 6 can be implemented by a computer. The speed and acceleration of car equipment 10 are detected by sensors (not shown) installed on car equipment 10.

[0034] A pair of car guide rails 16 and a pair of counterweight guide rails 17 are installed in the hoistway 1.

[0035] A pair of car guide rails 16 guide the movement of the car equipment 10. Thus, the car equipment 10 moves vertically along the pair of car guide rails 16.

[0036] A pair of counterweight guide rails 17 guide the movement of the counterweight 11. As a result, the counterweight 11 moves in the vertical direction along the pair of counterweight guide rails 17.

[0037] A car buffer 18 and a counterweight buffer 19 are installed at the bottom of the hoistway 1. The car buffer 18 is located below the car equipment 10. The counterweight buffer 19 is located below the counterweight 11.

[0038] An emergency stop device 13 is located at the bottom of the car 12. When the emergency stop device 13 is activated, it holds a pair of car guide rails 16. By holding the pair of car guide rails 16, the emergency stop device 13 brings the car equipment 10 to an emergency stop.

[0039] A compensating rope 21 is suspended from the car equipment 10 and the counterweight 11. The first end of the compensating rope 21 is connected to the lower part of the car 12. The second end of the compensating rope 21 is connected to the lower part of the counterweight 11.

[0040] A tensioning pulley 20 is installed at the bottom of the hoistway 1. A compensating rope 21 is wound around the tensioning pulley 20. The balance between the car equipment 10 side and the counterweight 11 side is compensated by the compensating rope 21.

[0041] When the speed of the car equipment 10 reaches an excessive speed, i.e., when a car travel abnormality based on excessive speed occurs, the safety monitoring device 6 generates a working command signal. Additionally, when the acceleration of the car equipment 10 reaches an excessive acceleration, i.e., when a car travel abnormality based on excessive acceleration occurs, the safety monitoring device 6 also generates a working command signal. The working command signal is a signal that activates the emergency stop device 13.

[0042] An emergency stop device 30 is provided in the car equipment 10. The emergency stop device 30 has a working device body 31 and a lifting bar 32.

[0043] The main body 31 of the working device is located on the upper part of the car equipment 10. The upper end of the lifting rod 32 is connected to the main body 31 of the working device. The lower end of the lifting rod 32 is connected to the emergency stop device 13. The main body 31 of the working device lifts the lifting rod 32 relative to the car equipment 10 according to the working command signal from the safety monitoring device 6. This activates the emergency stop device 13. No speed governor is installed in the elevator after installation. The emergency stop device 13 operates independently of the speed governor via the emergency stop working device 30.

[0044] For example, in the event of a breakage of the suspension 9, the car equipment 10 moves downwards due to gravity. If an abnormal car movement occurs due to excessive speed or excessive acceleration while the car equipment 10 is moving downwards, a work command signal is output from the safety monitoring device 6 to the working device body 31. Upon receiving the work command signal from the safety monitoring device 6, the working device body 31 lifts the lifting rod 32 relative to the car equipment 10. This activates the emergency stop device 13.

[0045] Figure 2 It means Figure 1A front view of the schematic structure of the emergency stop device 13. The emergency stop device 13 has a working lever 131, a linkage lever 132, a connecting rod 133, a first gripping part 134, and a second gripping part 135.

[0046] The working rod 131 is rotatable about the working rod shaft 131a. The working rod shaft 131a is supported on the car 12. The lower end of the lifting rod 32 is rotatably connected to the working rod 131.

[0047] The linkage 132 is rotatable about the linkage shaft 132a. The linkage shaft 132a is supported on the car 12.

[0048] The connecting rod 133 is rotatably connected to both the working rod 131 and the linkage rod 132. The connecting rod 133 transmits the rotation of the working rod 131 to the linkage rod 132. As a result, the linkage rod 132 rotates in conjunction with the working rod 131.

[0049] The working lever 131 is connected to the first holding part 134. The first holding part 134 holds one of the pair of car guide rails 16 by rotating the working lever 131 caused by the lifting of the lifting rod 32.

[0050] Linkage rod 132 is connected to second gripping part 135. Second gripping part 135 grips one of the pair of car guide rails 16 by rotating in conjunction with working rod 131.

[0051] The first holding part 134 holds one side of the car guide rail 16, and the second holding part 135 holds the other side of the car guide rail 16, thereby stopping the car equipment 10 in an emergency.

[0052] Next, the elevator installation method will be explained. Figure 3 This indicates installation. Figure 1 The flowchart illustrates the elevator installation method. The elevator installation method includes the following steps: scaffolding assembly (S1), elevator body setup (S2), temporary starting device setup (S3), car scaffolding setup (S4), and removal (S5).

[0053] <Scaffolding Assembly Process S1>

[0054] During elevator installation, a scaffolding assembly process S1 is performed. In scaffolding assembly process S1, scaffolding is assembled inside the shaft 1. By assembling the scaffolding inside the shaft 1, workers can utilize the scaffolding to perform tasks within the shaft 1.

[0055] <Lifting body installation procedure S2>

[0056] After the scaffolding assembly process S1, the hoisting body installation process S2 is performed. In the hoisting body installation process S2, a car equipment 10 and a counterweight 11 are installed in the hoistway 1. An emergency stop device 30 is installed on the car equipment 10. In the hoisting body installation process S2, since no power is supplied to the emergency stop device 30, the emergency stop device 13 cannot be activated by the emergency stop device 30.

[0057] In the lifting body installation step S2, a pair of car guide rails 16 and a pair of counterweight guide rails 17 are installed inside the hoistway 1. Additionally, in the lifting body installation step S2, the traction machine 3, the deflector pulley 4, the control device 5, and the safety monitoring device 6 are installed in the machine room 2. Furthermore, in the lifting body installation step S2, the suspension body 9 is wound around the drive rope pulley 8 and the deflector pulley 4, and the suspension body 9 is connected to the car equipment 10 and the counterweight 11. Thus, the car equipment 10 and the counterweight 11 can move vertically by the driving force of the traction machine 3. Furthermore, in the lifting body installation step S2, the car buffer 18 and the counterweight buffer 19 are installed at the bottom of the hoistway 1. Also, in the lifting body installation step S2, the tension pulley 20 is installed at the bottom of the hoistway 1, and the compensating rope 21 is connected to the car 12 and the counterweight 11.

[0058] <Temporary setup procedure for starting device S3>

[0059] After the lifting body setting procedure S2, the temporary setting procedure S3 for the starting device is performed. In the temporary setting procedure S3, the starting device is temporarily set up inside the hoistway 1. The starting device is a device that enables the emergency stop device 13 to operate.

[0060] Here, we will explain the elevator with a temporary installation device, in which a starting device is temporarily installed in the hoistway 1 through the temporary installation procedure S3 of the starting device.

[0061] Figure 4 It means through Figure 3 The temporary installation process S3 for the starting device is described in the side view of an elevator with a temporary installation device, where the starting device is temporarily installed in the hoistway 1. The starting device 40 has a starting device body 41 and a starting device rope 42. The starting device body 41 is positioned in the hoistway 1 at a height higher than the emergency stop device 13. The starting device rope 42 is connected to the starting device body 41. In addition, the starting device rope 42 is connected to the emergency stop device 13. In this embodiment, the starting device rope 42 is directly connected to the working rod 131 of the emergency stop device 13.

[0062] In an elevator equipped with a temporary setting device, an adjustable counterweight (not shown) is placed on the car equipment 10. As a result, the weight on the car equipment 10 side is heavier than the weight on the counterweight 11 side. When the driving force of the traction machine 3 stops and the braking force of the traction machine brake on the drive sheave 8 is released, the counterweight 11 moves upward, and the car equipment 10 moves downward.

[0063] Figure 5 It means Figure 4 A schematic structural diagram of the starting device 40. The main body 41 of the starting device has a winding section 43, a braking section 44, and a housing (not shown). The winding section 43 and the braking section 44 are housed inside a housing. The braking section 44 and the winding section 43 are integrated.

[0064] The winding section 43 winds up the starting device rope 42. The winding section 43 includes a winding body 431 and a winding spring 432. The winding body 431 is rotatably mounted on the housing. The winding body 431 is a cylindrical component. The winding body 431 is connected to the starting device rope 42. The winding body 431 winds up the starting device rope 42 by rotating relative to the housing in a first direction. The winding body 431 delivers the starting device rope 42 by rotating relative to the housing in the opposite direction to the first direction. The winding spring 432 generates an elastic restoring force that causes the winding body 431 to rotate in the first direction towards winding the starting device rope 42. Therefore, the winding section 43 generates a winding force via the winding spring 432 to wind the starting device rope 42 onto the winding body 431.

[0065] An opening (not shown) is provided in the housing. The starting device rope 42 extends from the winding part 43 through the opening in the housing to the outside of the housing. The starting device body 41 is installed in the shaft 1 with the opening in the housing facing downwards.

[0066] The starting device rope 42 is wound onto the winding body 431 by the winding force of the winding section 43. Furthermore, the starting device rope 42 is released from the winding body 431 against the winding force of the winding section 43. In this embodiment, the starting device rope 42 is made of metal. For example, a rope made of metal wire can be used as the starting device rope 42.

[0067] When the car equipment 10 moves downward, the starting device rope 42 is released from the winding body 431 while under tension. Conversely, when the car equipment 10 moves upward, the starting device rope 42 is wound onto the winding body 431 while under tension.

[0068] The winding force of the winding section 43 is less than the lifting force required to activate the emergency stop device 13. Therefore, even if the winding force of the winding section 43 is applied upwards to the working lever 131 of the emergency stop device 13 via the starting device rope 42, the emergency stop device 13 will not activate.

[0069] The winding body 431 rotates according to the movement of the starting device rope 42 relative to the starting device body 41. Since the starting device rope 42 is connected to the car equipment 10, the winding body 431 rotates according to the movement of the car equipment 10. Therefore, the rotational speed of the winding body 431 corresponds to the speed of the car equipment 10. Furthermore, the rotational acceleration of the winding body 431 corresponds to the acceleration of the car equipment 10.

[0070] The braking unit 44 has a rotating part 441 and a braking force generating part 442. The braking force generating part 442 has a fixed part 443 and a pair of movable parts 444. The fixed part 443 is fixed to the housing. The fixed part 443 is annular in shape. A plurality of receiving teeth 443a are provided on the inner periphery of the fixed part 443. The plurality of receiving teeth 443a are arranged along the circumference of the fixed part 443.

[0071] The rotating part 441 is fixed to the winding body 431. The rotating part 441 rotates integrally with the winding body 431. Thus, the rotating part 441 rotates according to the movement of the starting device rope 42 relative to the starting device body 41. The center of rotation of the rotating part 441 coincides with the center of the annular fixing part 443.

[0072] A pair of movable parts 444 are provided on the rotating part 441. Additionally, a pair of movable parts 444 are disposed inside the fixed part 443. The pair of movable parts 444 are each movable relative to the rotating part 441 in opposite directions via a guide mechanism (not shown). Each of the pair of movable parts 444 is provided with a hook tooth 444a opposite to the fixed part 443.

[0073] Each movable part 444 is movable relative to the rotating part 441 between a hook position and a release position. The hook position is when the hook tooth 444a of the movable part 444 hooks onto the receiving tooth 443a of the fixed part 443. The release position is when the hook tooth 444a of the movable part 444 disengages from the receiving tooth 443a of the fixed part 443. An elastic restoring force of a retaining spring (not shown) is applied to each movable part 444 toward the release position.

[0074] When the rotating part 441 rotates, a centrifugal force corresponding to the rotational speed of the rotating part 441 acts on each movable part 444. When the speed of the car equipment 10 increases, the rotational speed of the rotating part 441 also increases. Therefore, when the rotational speed of the rotating part 441 increases, the centrifugal force acting on each movable part 444 increases. Consequently, each movable part 444 overcomes the elastic restoring force of the holding spring and moves towards the hook position. Figure 5 Move in the direction of the arrow in the image.

[0075] If an abnormal car travel due to excessive speed occurs, at least one of the pair of movable parts 444 reaches the hook position. Thus, the hooking tooth 444a of the movable part 444 that has reached the hook position hooks onto the receiving tooth 443a of the fixed part 443. When the hooking tooth 444a hooks onto the receiving tooth 443a, the rotation of the rotating part 441 and the winding body 431 is stopped by the fixed part 443. As a result, the working braking force that activates the emergency stop device 13 is applied to the starting device rope 42. That is, the braking force generating part 442 generates the working braking force through the rotation of the rotating part 441 when an abnormal car travel due to excessive speed occurs.

[0076] For example, in the event of a breakage of the suspension 9, the car equipment 10 moves downward due to gravity. If an abnormal car travel occurs due to excessive speed while the car equipment 10 is moving downward, the braking unit 44 applies a working braking force to the starting device rope 42.

[0077] When the working braking force is applied to the starting device rope 42, the starting device rope 42 stops being sent out of the winding body 431. At this time, as the car equipment 10 continues to move downward, the working lever 131 of the emergency stop device 13 is lifted by the starting device rope 42. As a result, the emergency stop device 13 is activated, and the car equipment 10 stops in an emergency.

[0078] Returning to the description of this implementation method Figure 3 Explanation of the temporary setup procedure S3 for the starting device. For example... Figure 3 As shown, the temporary setup process S3 for the starting device includes the main body temporary setup process S31 and the connection process S32.

[0079] <Main Body Temporary Setup Procedure S31>

[0080] In the temporary installation step S3 of the starting device, after the installation step S2 of the lifting body, the temporary installation step S31 of the main body is performed. In the temporary installation step S31 of the main body, the main body 41 of the starting device is temporarily installed in the hoistway 1. The main body 41 of the starting device is temporarily installed at a position higher than the car equipment 10. The temporary installation of the main body 41 of the starting device is carried out on scaffolding assembled in the hoistway 1. The main body 41 of the starting device is installed on a fixed object fixed in the hoistway 1. Examples of fixed objects include brackets, building beams, etc.

[0081] <Connection process S32>

[0082] After the temporary setup process S31, the connection process S32 is performed. In the connection process S32, the starting device rope 42 is connected to the emergency stop device 13. In the connection process S32, the starting device rope 42, which is delivered from the winding section 43 overcoming the winding force of the winding section 43, is directly connected to the working rod 131 of the emergency stop device 13. The operation of connecting the starting device rope 42 to the emergency stop device 13 is carried out on scaffolding assembled inside the shaft 1.

[0083] <Car Scaffolding Process S4>

[0084] After the temporary setting procedure S3 of the starting device, the car scaffolding procedure S4 is performed. In the car scaffolding procedure S4, the car equipment 10 is used as scaffolding for work within the hoistway 1. That is, in the car scaffolding procedure S4, workers ride on the car equipment 10 to perform work within the hoistway 1. In the car scaffolding procedure S4, the car equipment 10 and the counterweight 11 are moved vertically by the driving force of the traction machine 3. In the car scaffolding procedure S4, the car equipment 10 and the counterweight 11 are moved at a low speed, lower than the normal operating speed. At this time, with the starting device rope 42 under tension, the starting device rope 42 is wound and delivered relative to the winding section 43 according to the movement of the car equipment 10. In the car scaffolding procedure S4, work within the hoistway 1 is performed with the emergency stop device 13 positioned lower than the starting device main body 41.

[0085] In the car scaffolding process S4, the scaffolding assembled in the hoistway 1 is disassembled. Additionally, in the car scaffolding process S4, landing equipment, including landing doors 15, is installed at each landing. Furthermore, in the car scaffolding process S4, hoistway equipment, including limit switches (not shown), is installed in the hoistway 1. Wiring and connection work are also performed within the hoistway 1 in the car scaffolding process S4.

[0086] In the car scaffolding process S4, if an abnormal car travel due to excessive speed occurs, the braking unit 44 applies a working braking force to the starting device rope 42. For example, in the event of a breakage of the suspension body 9, the car equipment 10 moves downward. In the car scaffolding process S4, if an abnormal car travel due to excessive speed occurs while the car equipment 10 is moving downward, the braking unit 44 applies a working braking force to the starting device rope 42. As a result, the emergency stop device 13 activates, and the car equipment 10 stops urgently. Therefore, it is possible to prevent the car equipment 10 from falling.

[0087] By completing the car scaffolding process S4, power can be supplied to the car equipment 10. This allows the use of the emergency stop device 30 installed on the car equipment 10. Furthermore, in Figure 4 It shows Figure 3 The elevator when the car scaffolding process S4 is completed.

[0088] <Removal Process S5>

[0089] After the car scaffolding operation S4, the removal operation S5 is performed. In the removal operation S5, the starting device 40 is removed. The removal of the starting device 40 is carried out while riding on the car equipment 10. In the removal operation S5, for example, in the event of a suspension body 9 breakage, if an abnormal car travel occurs due to excessive speed, the emergency stop device 13 is activated by the emergency stop working device 30. As a result, the car equipment 10 is brought to an emergency stop, preventing the car equipment 10 from falling.

[0090] After step S5 is removed, the installation of car-mounted equipment, including the car door 122, and wiring in the car equipment 10 are carried out. Then, the elevator installation is completed through trial runs.

[0091] In this type of elevator, the starting device body 41 is installed within the hoistway 1. The winding section 43 of the starting device body 41 winds up the starting device rope 42, which is connected to the emergency stop device 13 of the car equipment 10. Therefore, the space required for the starting device 40 within the hoistway 1 can be reduced. Furthermore, the flexibility in choosing where to install the starting device body 41 is increased. Thus, the starting device 40 can be easily installed within the hoistway 1, and the anti-fall function of the car equipment 10 can be easily ensured. Additionally, the car equipment 10, after installation, can be directly used for elevator installation work. Therefore, there is no need to install a new work platform within the hoistway 1, nor is there a need to install a new winch within the hoistway 1 to move the work platform. This reduces the burden of elevator installation work.

[0092] Furthermore, the braking unit 44 includes a rotating part 441 and a braking force generating part 442. The rotating part 441 rotates integrally with the winding body 431. The braking force generating part 442 generates working braking force by rotating the rotating part 441 when an abnormal car travel occurs due to excessive speed. Therefore, working braking force can be applied to the starting device rope 42 by utilizing the movement of the starting device rope 42 when an abnormal car travel occurs due to excessive speed. As a result, other drive units that generate working braking force are not required. Therefore, the work of installing the starting device body 41 in the hoistway 1 can be easily performed, further reducing the burden of elevator installation work.

[0093] Furthermore, the starting device rope 42 is made of metal. Therefore, even if welding work is being performed by personnel inside the shaft 1, damage to the starting device rope 42 can be prevented even if spatter or other debris from the welding work adheres to it. As a result, the function of the starting device 40, which activates the emergency stop device 13, can be more reliably ensured.

[0094] Furthermore, the weight on the car equipment 10 side is greater than the weight on the counterweight 11 side. Therefore, it is possible to prevent the car equipment 10 from moving upwards due to the imbalance between the car equipment 10 side and the counterweight 11 side. Thus, even if the braking force on the drive sheave 8 is released for some reason, it is possible to prevent the car equipment 10 from moving upwards against the operator's intention. Therefore, in the event of an abnormal car travel due to excessive speed, the emergency stop device 13 can operate more reliably.

[0095] Furthermore, in this elevator installation method, the car scaffolding process S4 is performed after the lifting body setting process S2, the main body temporary setting process S31, and the connection process S32. Therefore, the starting device 40 can be easily installed in the hoistway 1. Thus, when workers are riding in the car equipment 10 during the car scaffolding process S4, the starting device 40 can easily ensure the anti-fall function of the car equipment 10. Additionally, by performing the main body temporary setting process S31 before the car scaffolding process S4, the starting device main body 41 can be temporarily installed in a location within the hoistway 1 suitable for work during the car scaffolding process S4. Therefore, the starting device main body 41 can be temporarily installed in a location that does not obstruct workers riding in the car equipment 10, making work within the hoistway 1 during the car scaffolding process S4 easy. Furthermore, the car equipment 10, after installation, can be directly used for elevator installation work. Therefore, there is no need to install a new working platform in shaft 1, nor is it necessary to install a new winch in shaft 1 to move the working platform. This reduces the burden of elevator installation work.

[0096] Furthermore, in Embodiment 1, the braking force generating unit 442 utilizes the centrifugal force generated by the rotation of the rotating unit 441 to generate the working braking force. However, the structure of the braking force generating unit 442 is not limited to this.

[0097] For example, an eddy current braking device that utilizes eddy currents generated in a metal plate to generate working braking force can also be used as the braking force generating unit 442. In this case, the rotating part 441 is a metal plate that rotates integrally with the winding body 431. In addition, the braking force generating unit 442 has a fixing part and a permanent magnet. The fixing part is fixed to the housing. The permanent magnet is fixed to the fixing part in a state opposite to the rotating part.

[0098] When an eddy current braking device is used as the braking force generating unit 442, eddy currents are generated in the rotating unit 441 through the magnetic flux of the permanent magnet when the rotating unit 441 rotates. The magnitude of the eddy current varies depending on the rotational speed of the rotating unit 441. The higher the rotational speed of the rotating unit 441, the greater the magnitude of the eddy current. As a result, a braking force corresponding to the magnitude of the eddy current is applied to the rotating unit 441 and the winding body 431. The greater the magnitude of the eddy current, the greater the magnitude of the braking force applied to the rotating unit 441 and the winding body 431.

[0099] When the eddy current braking device is used as the braking force generating unit 442, the braking force applied to the rotating part 441 and the winding body 431 is less than the working braking force when no abnormal car travel based on excessive speed occurs. If an abnormal car travel based on excessive speed occurs, the rotational speed of the rotating part 441 becomes too high, and the magnitude of the eddy current generated in the rotating part 441 becomes too high. As a result, the braking force applied to the rotating part 441 and the winding body 431 reaches the magnitude of the working braking force. Therefore, the braking force generating unit 442 can generate the working braking force, enabling the emergency stop device 13 to operate.

[0100] Thus, even if an eddy current braking device is used as the braking force generating unit 442, the braking force generating unit 442 can generate working braking force by rotating the rotating unit 441 when an abnormal car travel occurs due to excessive speed. Therefore, other drive units that generate working braking force are not required. Consequently, the work of installing the starting device body 41 within the hoistway 1 can be easily performed, further reducing the burden of elevator installation work.

[0101] Examples of starting devices 40 that use an eddy current braking device as the braking force generating unit 442 include automatic tethers and safety blocks. Automatic tethers are fall arrest devices used in activities such as rock climbing to prevent a person from falling. Safety blocks are fall arrest devices used in high-altitude operations such as using ladders to prevent a person from falling.

[0102] In addition, in Embodiment 1, a brake unit 44 for applying working braking force to the starter rope 42 when an abnormal car travel based on excessive speed occurs is applied to the starter body 41. However, a brake unit 44 for applying working braking force to the starter rope 42 when an abnormal car travel based on excessive acceleration occurs may also be applied to the starter body 41. In this case, the structure of the brake unit 44 for excessive acceleration is the same as that of the brake unit 44 for excessive speed, except for the structure of the braking force generating part 442. The braking force generating part 442 in the brake unit 44 for excessive acceleration has a fixed part, a mass body, and a movable claw.

[0103] When the braking unit 44 for excessive acceleration is applied to the starting device body 41, the fixed part is fixed to the housing. The mass body is held in the rotating part. The mass body moves relative to the rotating part in the opposite direction to the rotation direction of the rotating part by the inertial force when an abnormal car travel occurs based on excessive acceleration. The greater the rotational acceleration of the rotating part, the greater the magnitude of the inertial force of the mass body relative to the rotating part. The movable pawl is provided in a movable manner in the rotating part. The movable pawl is hooked to the fixed part by being pressed by the mass body moving relative to the rotating part. A working braking force is applied to the starting device rope 42 by the movable pawl hooking to the fixed part.

[0104] In this way, by applying the braking part 44 for excessive acceleration to the starting device 40, a working braking force can be applied to the starting device rope 42 when a car travel abnormality based on excessive acceleration occurs. Therefore, when the car equipment 10 moves downward, even if a car travel abnormality based on excessive acceleration occurs, the emergency stop device 13 can be activated to bring the car equipment 10 to an emergency stop.

[0105] Implementation method 2.

[0106] Figure 6 This is a schematic structural diagram showing the starting device 40 included in the elevator with temporary installation device according to Embodiment 2. The starting device 40 in Embodiment 2 includes a starting device body 41, a detection unit 52, and a battery (not shown). The starting device body 41 includes a winding unit 51, a braking unit 53, and a housing (not shown). The winding unit 51, the detection unit 52, the braking unit 53, and the battery are housed inside a single housing.

[0107] The winding unit 51 includes a winding shaft 511, a winding body 512, and a winding spring (not shown). The winding body 512 is disposed on the housing via the winding shaft 511. The winding body 512 is rotatable relative to the housing about the winding shaft 511. The winding body 512 is a ring-shaped component. The winding body 512 is connected to the starting device rope 42. The winding body 512 winds up the starting device rope 42 by rotating relative to the housing in a first direction. The winding body 512 delivers the starting device rope 42 by rotating relative to the housing in the opposite direction to the first direction. The winding spring generates an elastic restoring force that causes the winding body 512 to rotate in the first direction to wind the starting device rope 42. Therefore, the winding unit 51 generates a winding force by means of the winding spring to wind the starting device rope 42 onto the winding body 512.

[0108] The winding force of the winding section 51 is less than the lifting force required to activate the emergency stop device 13. Therefore, even if the winding force of the winding section 51 is applied upwards to the working lever 131 of the emergency stop device 13 via the starting device rope 42, the emergency stop device 13 will not activate.

[0109] The winding body 512 rotates according to the movement of the starting device rope 42 relative to the starting device body 41. Since the starting device rope 42 is connected to the car equipment 10, the winding body 512 rotates according to the movement of the car equipment 10. Therefore, the rotational speed of the winding body 512 becomes a speed corresponding to the speed of the car equipment 10.

[0110] The detection unit 52 detects abnormal car travel caused by excessive speed based on the rotation of the winding body 512. The detection unit 52 includes a mounting shaft 521, a centrifugal counterweight 522, a return spring 523, and a switch 524.

[0111] A centrifugal counterweight 522 is mounted on the winding body 512 via a mounting shaft 521. The centrifugal counterweight 522 is rotatable relative to the winding body 512 about the mounting shaft 521. A protrusion 522a is fixed to the centrifugal counterweight 522. In the detection unit 52, the centrifugal counterweight 522 rotates about the mounting shaft 521, thereby changing the distance from the axis of the winding shaft 511 to the protrusion 522a.

[0112] The return spring 523 is connected to the centrifugal counterweight 522 and the winding body 512. The centrifugal counterweight 522 rotates relative to the winding body 512 against the elastic restoring force of the return spring 523, thereby causing the protrusion 522a to move away from the axis of the winding shaft 511.

[0113] Switch 524 is mounted in the housing. Furthermore, switch 524 is positioned further away from the axis of the take-up shaft 511 than the centrifugal counterweight 522. Switch 524 has a switch body 524a and an operating part 524b. The operating part 524b is provided in the switch body 524a. The operating part 524b protrudes from the switch body 524a toward the take-up shaft 511.

[0114] When the winding body 512 rotates, a centrifugal force corresponding to the rotational speed of the winding body 512 acts on the centrifugal counterweight 522. As the speed of the car equipment 10 increases, the rotational speed of the winding body 512 also increases. Therefore, as the rotational speed of the winding body 512 increases, the centrifugal force acting on the centrifugal counterweight 522 increases. Consequently, as the rotational speed of the winding body 512 increases, the centrifugal counterweight 522 overcomes the elastic restoring force of the return spring 523 and rotates relative to the winding body 512, causing the protrusion 522a to move away from the axis of the winding shaft 511.

[0115] If an abnormal car travel due to excessive speed occurs, the protrusion 522a contacts the operating unit 524b. This activates the operating unit 524b. When the operating unit 524b is activated, the switch 524 detects the abnormal car travel due to excessive speed via the switch body 524a.

[0116] The battery supplies power to the braking unit 53 of the starting device body 41. Switch 524 controls the power supply from the battery to the braking unit 53. Switch 524 supplies power from the battery to the braking unit 53 when no abnormal car travel based on excessive speed is detected. Conversely, switch 524 stops supplying power from the battery to the braking unit 53 when an abnormal car travel based on excessive speed is detected.

[0117] The braking unit 53 is positioned away from the winding unit 51 in the direction in which the starting device rope 42 is delivered from the winding unit 51. The braking unit 53 includes a receiving part 531, a movable part 532, an electromagnet 533, and a plurality of braking springs 534.

[0118] Electromagnet 533 is fixed to the housing. Support portion 531 is fixed to electromagnet 533 via a fixing member (not shown). Support portion 531 is positioned away from electromagnet 533. Movable portion 532 is supported on electromagnet 533. Movable portion 532 is positioned between electromagnet 533 and support portion 531. Multiple brake springs 534 are positioned between movable portion 532 and electromagnet 533. Starting device rope 42 passes between support portion 531 and movable portion 532.

[0119] Each brake spring 534 applies an elastic restoring force to the movable part 532 toward the bearing part 531. When power to the electromagnet 533 is stopped, the elastic restoring force of each brake spring 534 holds the starting device rope 42 between the bearing part 531 and the movable part 532. Thus, the brake part 53 applies a working braking force to the starting device rope 42.

[0120] Electromagnet 533 generates an electromagnetic attraction force by supplying power from a battery to it. Through the generation of this electromagnetic attraction force, movable part 532 overcomes the elastic restoring force of each braking spring 534 and moves away from bearing part 531. This releases the bearing part 531 and movable part 532 from their grip on the starting device rope 42. Therefore, when power is supplied from the battery to electromagnet 533, braking part 53 allows the starting device rope 42 to move relative to the starting device body 41.

[0121] For example, in the event of a breakage of the suspension 9, the car equipment 10 moves downwards due to gravity. If an abnormal car movement based on excessive speed occurs while the car equipment 10 is moving downwards, the detection unit 52 detects this abnormality. Consequently, the detection unit 52 stops the power supply from the battery to the electromagnet 533.

[0122] When power is stopped from being supplied to the electromagnet 533, the starting device rope 42 is held between the bearing part 531 and the movable part 532. As a result, a working braking force is applied to the starting device rope 42 by the braking part 53.

[0123] When the working braking force is applied to the starting device rope 42, the starting device rope 42 stops being sent out of the winding body 512. At this time, as the car equipment 10 continues to move downward, the working lever 131 of the emergency stop device 13 is lifted by the starting device rope 42. As a result, the emergency stop device 13 is activated, and the car equipment 10 stops in an emergency. The other structures in this embodiment are the same as in embodiment 1.

[0124] In such an elevator, when the detection unit 52 detects an abnormal car travel due to excessive speed, the detection unit 52 stops the power supply from the battery to the braking unit 53. The braking unit 53 applies a working braking force to the starting device rope 42 by stopping the power supply from the battery to the braking unit 53. Therefore, it is possible to detect abnormal car travel due to excessive speed using battery power. Thus, it is not necessary to supply power to the starting device body 41 from the outside. Therefore, the burden of installation work on the starting device body 41 within the hoistway 1 can be further reduced.

[0125] Furthermore, in Embodiment 2, the detection unit 52 can also detect abnormal car travel due to excessive speed by directly measuring the moving speed of the starting device rope 42 using a speed sensor. In this case, power is supplied to the detection unit 52 from the battery. The detection unit 52 includes a speed sensor and a control unit. The speed sensor directly measures the moving speed of the starting device rope 42. The speed sensor is positioned between the winding unit 51 and the braking unit 53. The control unit detects abnormal car travel due to excessive speed based on the measurement results of the speed sensor. In addition, when the control unit detects an abnormal car travel due to excessive speed, it stops supplying power from the battery to the braking unit 53.

[0126] Alternatively, in Embodiment 2, the detection unit 52 can also detect abnormal car operation due to excessive acceleration by directly measuring the acceleration of the starter rope 42 using an accelerometer. In this case, power is supplied to the detection unit 52 from the battery. The detection unit 52 includes an accelerometer and a control unit. The accelerometer directly measures the acceleration of the starter rope 42. The accelerometer is positioned between the winding unit 51 and the braking unit 53. The control unit detects abnormal car operation due to excessive acceleration based on the measurement results of the accelerometer. Furthermore, when the control unit detects an abnormal car operation due to excessive acceleration, it stops supplying power from the battery to the braking unit 53.

[0127] Alternatively, in embodiment 2, the detection unit 52 may also be provided in the car equipment 10. In this case, a control cable is temporarily provided from the car equipment 10 to the starter body 41 in order to send the detection result of the detection unit 52 to the starter body 41. In addition, in this case, the power supply to the detection unit 52 is provided by a battery provided in the car equipment 10. As the sensor included in the detection unit 52 provided in the car equipment 10, a roller speed sensor, an APS (Absolute Positioning System) sensor, etc. are used. The roller speed sensor generates a signal corresponding to the rotational speed of the roller that contacts the car guide rail 16. The roller of the roller speed sensor rolls on the car guide rail 16 according to the movement of the car equipment 10. The APS sensor calculates the speed of the car equipment 10 by reading the code tape arranged in the vertical direction. The APS sensor reads the code tape according to the movement of the car equipment 10. Alternatively, as a sensor included in the detection unit 52, an acceleration sensor that directly detects the acceleration of the car equipment 10 may be installed in the car equipment 10.

[0128] Implementation method 3.

[0129] Figure 7This is a side view of the elevator with a temporary installation device according to Embodiment 3. A handle 61 is provided on the starting device rope 42. In this embodiment, the handle 61 is provided at the middle of the starting device rope 42. The starting device rope 42 has a connecting end that connects to the emergency stop device 13. When the starting device rope 42, which is delivered from the starting device body 41, is connected to the emergency stop device 13, the handle 61 is located within the reach range set above the car equipment 10. The reach range is the range that the operator 60 riding on the car equipment 10 can reach.

[0130] The shape of the handle 61 can be rod-shaped, ring-shaped, etc. The shape of the handle 61 is not particularly limited. Other structures in this embodiment are the same as in Embodiment 1.

[0131] In this elevator, a handle 61 is provided on the starting device rope 42. Therefore, the operator 60, riding in the car equipment 10, can operate the starting device rope 42 by holding the handle 61. Thus, by pulling the handle 61 upwards, the operator 60 can activate the emergency stop device 13. Furthermore, by pulling the handle 61 downwards, the operator 60 can cause the starting device body 41 to apply a working braking force to the starting device rope 42. Therefore, even without abnormal car travel due to excessive speed or excessive acceleration, the emergency stop device 13 can be forcibly activated by the operator 60's operation of the handle 61.

[0132] Implementation method 4.

[0133] Figure 8 This is a side view of the elevator with a temporary installation device according to embodiment 4. Figure 9 It means Figure 8 A top view of the car equipment 10. U-bolts 65, serving as vibration damping components, are provided on the car 12. The U-bolts 65 are located on the side of the car 12. Both ends of the U-bolts 65 are mounted on the side of the car 12.

[0134] The starting device rope 42 passes through the inside of the U-bolt 65. Therefore, when viewing the car equipment 10 from above, as... Figure 9 As shown, the starting device rope 42 is surrounded by a U-bolt 65. Other structures in this embodiment are the same as in Embodiment 1.

[0135] In this elevator, U-bolts 65 are installed in the car 12. Furthermore, when viewed from above, the starting device rope 42 is surrounded by the U-bolts 65. Therefore, the amplitude of the starting device rope 42 during lateral vibration can be suppressed by the U-bolts 65. This prevents the starting device rope 42 from easily getting caught on protrusions in the car 10 or similar structures within the hoistway 1. In particular, there are multiple protrusions on the car 10. Therefore, by installing the U-bolts 65 as vibration damping components in the car 12, the effect of preventing the starting device rope 42 from getting caught on protrusions is enhanced. This prevents the emergency stop device 13 from malfunctioning due to the starting device rope 42 getting caught on protrusions.

[0136] In addition, in embodiment 4, the U-bolt 65 is used as a vibration damping component. However, the vibration damping component is not limited to this. For example, a ring-shaped component may also be provided as a vibration damping component in the car 12.

[0137] Alternatively, the mounting portion of the vibration damping component relative to the car 12 can be a permanent magnet. In this case, the vibration damping component is mounted to the car 12 by the magnetic force of the permanent magnet. In this way, the vibration damping component can be mounted to the car 12 without machining the car 12, making it easy to install the vibration damping component to the car 12.

[0138] Implementation method 5.

[0139] Figure 10 This is a side view of the elevator with a temporary installation device according to Embodiment 5. A hook-shaped member 71, serving as a load-absorbing part, is provided on the starting device rope 42. In this embodiment, the hook-shaped member 71 is provided in the middle of the starting device rope 42. The hook-shaped member 71 is more deformable than the starting device rope 42 in the length direction.

[0140] The hook-shaped component 71 is provided with a load absorption limit load level. If a load greater than or equal to the load absorption limit load level is applied to the hook-shaped component 71, the hook-shaped component 71 will deform.

[0141] The load absorption unit's ultimate load rating is smaller than the starting device's ultimate load rating. The starting device's ultimate load rating is the load rating at which the starting device body 41 may fail when the load is applied to it via the starting device rope 42.

[0142] When the emergency stop device 13 is activated and an excessive load is applied to the starting device rope 42, the hook-shaped component 71 deforms and absorbs the load. Therefore, the load acting on the starting device body 41 via the starting device rope 42 is less than the limit load rating of the starting device.

[0143] Furthermore, the ultimate load rating of the load absorption section is greater than the lifting force required to activate the emergency stop device 13. Therefore, the hook-shaped member 71 does not deform when the starting device rope 42 is lifted relative to the car equipment 10. Consequently, when the starting device body 41 applies a working braking force to the starting device rope 42, sufficient lifting force is transmitted from the starting device body 41 to the emergency stop device 13 via the starting device rope 42. Other structural features in this embodiment are the same as in Embodiment 1.

[0144] In such an elevator, a hook-shaped component 71, serving as a load-absorbing part, is provided on the starting device rope 42. The hook-shaped component 71 deforms more easily than the starting device rope 42 along its length. Therefore, even if an excessive load is applied to the starting device rope 42 from the time the emergency stop device 13 operates until the car equipment 10 stops, the hook-shaped component 71 can deform to absorb the load. This reduces the magnitude of the load acting on the starting device body 41 via the starting device rope 42. Consequently, it prevents malfunctions of the starting device body 41 and damage to the fixtures on which the starting device body 41 is mounted.

[0145] In addition, in embodiment 5, the hook-shaped member 71 is used as a load-absorbing part. However, it is not limited to this. For example, a shock absorber can also be provided as a load-absorbing part on the starter rope 42. Even so, when an excessive load is applied to the starter rope 42, the shock absorber will deform in the length direction of the starter rope 42. Thus, the load is absorbed by the shock absorber. Alternatively, a corrugated part formed by bending a portion of the starter rope 42 in a corrugated shape and then solidifying it can also be provided as a load-absorbing part on the starter rope 42. Even so, when an excessive load is applied to the starter rope 42, the corrugated part will unfold, thereby deforming in the length direction of the starter rope 42. Thus, the load is absorbed by the corrugated part.

[0146] In addition, in embodiment 5, the hook-shaped component 71 is provided at the middle part of the starting device rope 42. However, it is not limited to this. For example, the connecting end of the starting device rope 42 can also be connected to the emergency stop device 13 via the hook-shaped component 71.

[0147] Furthermore, in Embodiment 3, the structure of providing a handle 61 on the starting device rope 42 is applied to Embodiment 1. However, the structure of providing a handle 61 on the starting device rope 42 can also be applied to Embodiments 2, 4, and 5.

[0148] Furthermore, in Embodiment 4, the structure with vibration damping components installed on the car 12 is applied to Embodiment 1. However, the structure with vibration damping components installed on the car 12 can also be applied to Embodiments 2, 3, and 5.

[0149] Furthermore, in Embodiment 5, the structure with a load-absorbing portion provided on the starting device rope 42 is applied to Embodiment 1. However, the structure with a load-absorbing portion provided on the starting device rope 42 may also be applied to Embodiments 2 to 4.

[0150] Furthermore, in each of the above embodiments, the starting device rope 42 is made of metal. However, if there is no concern that spatter or other debris from welding operations may adhere to the starting device rope 42, the starting device rope 42 may not be made of metal. Therefore, the starting device rope 42 may also be made of resin or the like.

[0151] Furthermore, in each of the above embodiments, the weight of the car equipment 10 side is greater than the weight of the counterweight 11 side. However, the weight of the car equipment 10 side and the weight of the counterweight 11 side can also be the same. Even so, it is possible to prevent the car equipment 10 from moving upwards against the operator's intention. That is, the weight of the car equipment 10 side only needs to be greater than or equal to the weight of the counterweight 11 side.

[0152] Furthermore, in each of the above embodiments, the starting device rope 42 is directly connected to the emergency stop device 13. However, for example, the starting device rope 42 can also be connected to the emergency stop device 13 via the lifting rod 32 of the emergency stop working device 30. In this way, the working space when connecting the starting device rope 42 to the lifting rod 32 can be easily ensured. As a result, the workload of installing the starting device 40 in the shaft 1 can be further reduced.

[0153] Furthermore, in each of the above embodiments, the main body temporary installation step S31 is performed after the lifting body installation step S2, and the connection step S32 is performed after the main body temporary installation step S31. However, it is also possible to perform the connection step S32 after the lifting body installation step S2, and the main body temporary installation step S31 after the connection step S32.

[0154] Furthermore, in each of the above embodiments, a counter can be provided in the starting device 40 to count the number of times an action is performed, namely, the action by which the starting device body 41 applies a working braking force to the starting device rope 42. In this way, the usability of the starting device 40 can be determined based on the number of times the starting device body 41 performs its actions. This eliminates the possibility of starting devices 40 with reduced reliability, thereby improving the reliability of the starting device 40 used. The counter can be a mechanical counter or an electrical counter. When using an electrical counter, a battery that supplies power to the counter is provided in the starting device body 41.

[0155] Furthermore, in each of the above embodiments, a counter may be provided in the starting device 40 to count the number of times the length of the starting device rope 42 extended from the starting device body 41 exceeds a reference length. In this way, the usability of the starting device 40 can be determined based on the number of times the starting device rope 42 is extended beyond the reference length from the starting device body 41. This eliminates the possibility of a starting device 40 with reduced reliability, thus improving the reliability of the starting device 40 used. The counter can be a mechanical counter or an electrical counter. When using an electrical counter, a battery that supplies power to the counter is provided in the starting device body 41.

[0156] Furthermore, in each of the above embodiments, the suspension method of suspending the car equipment 10 and the counterweight 11 using the suspension body 9 is a 1:1 rope winding method. However, it is not limited to this.
