Description

Technical Field

[0001] The present invention relates to a device for assisting in the installation of elevator guide rails.

Background Art

[0002] Guide rails are cut to an appropriate length at a factory, shipped, and then transported to the installation site. At the installation site, they are connected in a row continuously from the bottom (pit) to the top in the hoistway and attached to the wall surface of the hoistway. At this time, processes such as centering, cleaning, and fitting are required over the entire length of the guide rail. This is because if the installation accuracy or surface condition of the guide rail is poor, it will cause unfavorable events for the operation of the elevator, such as a poor riding comfort of the car, vibration, and abnormal noise.

[0003] Normally, these processes are performed by workers. However, it is a great burden for workers to perform operations by climbing up and down between the bottom and the top in the hoistway for two pairs (four rows) of guide rails, namely, the guide rails for the car and the guide rails for the counterweight. Therefore, the automation of these processes, that is, the development of a guide rail installation assistance device, has become an important issue.

[0004] As an example of such development, Patent Documents 1 to 3 describe various guide rail installation support devices. Specifically, Patent Document 1 describes a guide rail alignment device that automates the alignment of guide rails, Patent Document 2 describes a guide rail cleaning device that automates the cleaning of guide rails, and Patent Document 3 describes a guide rail sliding device that automates the sliding of guide rails. These disclose two forms: i) a form in which the device moves (self-propels) on the guide rail by mounting an automation function unit on the device base and mounting a lifting drive unit on the device base, and ii) a form in which the device moves on the guide rail by utilizing the lifting drive force of the lifting machine by mounting an automation function unit on the device base and suspending and supporting the device base with a lifting machine.

[0005] [Patent Document 1] Japanese Patent Application Publication No. 7-242379 [Patent Document 2] International Publication No. 2020 / 136712 [Patent Document 3] International Publication No. 2019 / 142362 [Overview of the project] [Problems that the invention aims to solve]

[0006] However, in form i), the overall weight of the guide rail installation support device is large, which has the disadvantage of placing a heavy burden on workers when attaching, detaching, and transporting the device to the guide rail. Also, in form ii), a pendant switch suspended from the lifting machine is used, requiring the worker to operate the lifting machine, and since some parts are manual, it has the disadvantage of not being able to achieve complete automation.

[0007] Therefore, the present invention has been made in view of these circumstances, and aims to provide an elevator guide rail installation support device that can reduce the burden on workers through weight reduction and achieve complete automation. [Means for solving the problem]

[0008] The elevator guide rail installation support device according to the present invention is The system comprises a main unit equipped with a functional unit and a control unit, configured to be movable on guide rails extending vertically within the hoistway, and a lifting machine as a secondary device installed in the upper part of the hoistway to suspend and support the main unit. Re, The main unit is equipped with a wireless communication transmitter, the lifting machine is equipped with a wireless communication receiver, and the control unit of the main unit is configured to remotely operate the lifting machine by issuing an upward or downward command to the lifting machine via wireless communication. This is an elevator guide rail installation support device. In the first invention, The receiver unit of the lifting machine is a receiver that is installed in place of the pendant switch, equipped with a plug compatible with the pendant switch connection plug of the lifting machine. In the second invention, The main unit comprises two device bases connected via a drive mechanism so as to be movable relative to each other on a horizontal plane, one of which has a function to fix itself so as not to move on the horizontal plane, and the other device base has a function to grip the guide rail. The drive mechanism includes an eccentric cam, whose angle changes in accordance with the change in the rotation angle of the motor's drive shaft, as part of the configuration on one of the two device bases, and a guide groove into which the eccentric cam is inserted, as part of the configuration on the other of the two device bases. In the third invention, The main unit has the function of cleaning the surface of the guide portion of the guide rail while moving between the upper limit position and the lower limit position. In the fourth invention, The main unit has the function of stopping at a position where there is a step on the surface of the guide portion of the guide rail and performing a sliding adjustment of the surface of the guide portion of the guide rail.

[0009] As one embodiment of the elevator guide rail installation support device according to the present invention, The main unit includes a detection unit that detects when the main unit reaches a specific position in its movement path along the guide rail. The control unit of the main unit is configured to stop issuing commands that were previously issued in response to detection by the detection unit. This configuration can be adopted.

[0010] As one embodiment of the elevator guide rail installation support device according to the present invention, The specific position is any one or two or more of the support position of the guide rail, the position where a step occurs on the surface of the guide portion of the guide rail, the upper limit position, or the lower limit position. The configuration with can be adopted.

Advantages of the Invention

[0015] According to the present invention, as a moving drive source of the main device, a hoist for suspending and supporting the main device is used, and the hoist is remotely operated by the control unit of the main device. As a result, the overall weight of the main device does not increase, and the operation of the hoist by an operator becomes unnecessary. Therefore, according to the present invention, it is possible to reduce the burden on the operator due to weight reduction and achieve full automation.

[0017] <Elevator and guide rail configuration> The following describes the elevator guide rail installation support device, but first, we will explain the configuration of the elevator and guide rails.

[0018] As shown in Figures 1 and 2(a), the elevator comprises a hoistway 1, a car, and a car drive mechanism. The hoistway 1 extends vertically within a building with multiple floors. A pair (two rows) of guide rails 2, 2 are attached to two opposing walls 1a, 1a of the hoistway 1, extending vertically. The car moves up and down within the hoistway 1, guided by the guide rails 2, as guide bodies attached to four locations (top, bottom, left, and right) slide along the guide rails 2. The car drive mechanism controls the movement of the car and stops it at the designated floor.

[0019] The guide rail 2 has a T-shape in plan view and comprises a base portion 20 and a projection portion 21. The base portion 20 is a strip-shaped plate extending in the vertical direction and is arranged parallel to the wall surface 1a of the elevator shaft 1 at a predetermined distance. The projection portion 21 is a strip-shaped plate extending in the vertical direction, is connected to the central part of the base portion 20 at one side, and protrudes perpendicularly from the base portion 20.

[0020] The projection 21 comprises a connecting portion 210 and a guide portion 211. The connecting portion 210 connects the base portion 20 and the guide portion 211. The connecting portion 210 is narrower than the guide portion 211 and forms a constriction in the projection 21. The guide portion 211 slides against the guide body of the cage and guides the guide body to move linearly in the vertical direction. The guide portion 211 comprises two guide surfaces 211a, 211a and a tip surface 211b. The two guide surfaces 211a, 211a are surfaces located in the thickness direction of the guide portion 211 and are parallel or tapered, with the tip side being narrower. The tip surface 211b is a surface located between the tip edges of the two guide surfaces 211a, 211a and is a flat surface or a curved surface such as an arc surface.

[0021] The guide rail 2 has an appropriate length and is extended vertically by connecting the ends of two guide rails 2, 2. One end of the guide rail 2 has a protrusion 22 on its end face, and the other end of the guide rail 2 has a groove 23 on its end face. The protrusion 22 and groove 23 are formed along the front-rear direction and extend between the front end surface 211b and the back surface of the base 20. The ends of the upper and lower guide rails 2, 2 are connected without shifting in the left-right direction by the interlocking of the protrusion 22 and groove 23.

[0022] The upper and lower guide rails 2,2 are connected at both ends using a connecting material 25 such as a cover plate. The connecting material 25 is plate-shaped and is placed against the back of both ends (bases 20) of the upper and lower guide rails 2,2, and is positioned across both ends. Multiple screw holes or through holes are formed in the upper and lower halves of the connecting material 25, and through holes are formed at the ends of the guide rails 2 corresponding to these holes. The connecting material 25 is connected to the ends of the guide rails 2 using a fastener 250.

[0023] The guide rail 2 is fixed to the wall surface 1a of the elevator shaft 1 at appropriate points along its length using guide rail support members 27. The guide rail support member 27 comprises a wall bracket 270, a rail bracket 271, and a rail clip 273. The wall bracket 270 is fixed to the wall surface 1a of the elevator shaft 1 using fasteners. Alternatively, the wall bracket 270 is fixed to a beam or frame provided along the wall surface 1a of the elevator shaft 1 using fasteners and / or welding. The rail bracket 271 is positioned relative to the wall bracket 270 and then fixed to the wall bracket 270 using fasteners and welding. The rail clip 273 is fixed to the vertical surface of the rail bracket 271 using fasteners 274 at two points on the left and right of the base 20 of the guide rail 2, while in contact with the outer surface of the base 20.

[0024] <Guide rail installation procedure> Guide rail 2 is installed during elevator installation work in the following procedure. Note that wall bracket 270 is attached and fixed to the wall surface 1a of the hoistway 1 in advance, prior to or during the elevator installation work.

[0025] (Installation process for the first guide rail) At the lowest point (pit) of the elevator shaft 1, the worker adjusts the horizontal position of the rail bracket 271, which is fixed to the first guide rail 2, relative to the corresponding wall bracket 270, thereby aligning it with the first guide rail 2. After the alignment is complete, the rail bracket 271 is fixed to the wall bracket 270 (final fixing).

[0026] (Connection process) The worker uses a lifting machine to suspend the second guide rail 2, places it on top of the first guide rail 2, and connects both ends of the two guide rails 2, 2.

[0027] (Installation process for the second guide rail) The worker temporarily attaches the rail bracket 271, which is fixed to the second guide rail 2, to the corresponding wall bracket 270.

[0028] (Connection process) The worker uses a lifting machine to suspend the third guide rail 2, places it on top of the second guide rail 2, and connects both ends of the two guide rails 2, 2.

[0029] The workers repeat these steps to connect the guide rails 2 sequentially upwards, installing them all the way to the top of the elevator shaft 1.

[0030] (Centering and final fixing process using a guide rail centering device) At this point, the second and subsequent guide rails 2 have not yet been aligned, and the rail brackets 271 that will be fixed to the second and subsequent guide rails 2 are not yet permanently fixed to the wall brackets 270. Therefore, the guide rail alignment device (hereinafter abbreviated as "alignment device"), which is one of the guide rail installation support devices (hereinafter abbreviated as "installation support device"), is used to perform these tasks.

[0031] (Cleaning process using guide rail cleaning device) Guide rails 2 are cut to the appropriate length at the factory, holes are drilled at the ends, and then shipped out. They are then transported to the installation site and installed there. To prevent the guide rails 2 from rusting during this time, they are coated with rust-preventive oil at the factory before being shipped out. Rust-preventive oil is not necessary for elevator operation. Furthermore, if the rust-preventive oil is left as is, dust and other debris will easily adhere to it, which is undesirable for elevator operation. Therefore, prior to elevator operation, a guide rail cleaning device (hereinafter abbreviated as "cleaning device"), which is one of the installation support devices, cleans the surface of the guide section 211 of the guide rail 2 to remove the rust-preventive oil.

[0032] (Lapping process using a guide rail lapping device) Guide rail 2 has some manufacturing tolerances in dimensions such as the width of the guide section 211 in the left-right direction and the length of the protruding section 21. As a result, the surfaces of the two guide sections 211, 211 may not be flush at the connecting parts at both ends of the upper and lower guide rails 2, 2, resulting in a step. Even if the step is small, it can cause vibration and abnormal noise when the elevator car's guide body passes over the step during elevator operation. Therefore, prior to elevator operation, a guide rail sliding device (hereinafter abbreviated as "sliding device") is used to perform a sliding process that eliminates the step on the surface of the guide section 211 and finishes the surface of the guide section 211 to a smooth surface.

[0033] <Common configuration of installation support devices> As shown in Figure 2(b), the installation support device 3 is composed of a main device 4 and a lifting machine 5 as a secondary device.

[0034] The main unit 4 is configured to move along the guide rail 2 while gripping it. The main unit 4 is suspended and supported by the lifting machine 5, and moves upward (up) as the lifting machine 5 winds up the wire, and moves downward (down) as the lifting machine 5 winds down the wire.

[0035] The main unit 4 is equipped with a device base. The device base constitutes the overall frame of the main unit 4. Engagement parts such as eye bolts are attached to the upper part of the device base. Hooks attached to the ends of wires, chains, ropes, etc., that hang down from the body of the lifting machine 5 engage with the engagement parts, suspending and supporting the device base. Various functional parts are mounted on the device base.

[0036] The main unit 4 is equipped with guide bodies. The guide bodies are roller guides attached to the upper and lower parts of the device base. Two rollers each abut against the guide surface 211a of the guide portion 211 of the guide rail 2 and have flange portions at their ends that engage with the constricted portion 210 of the guide rail 2. The other roller abuts against the front end surface 211b of the guide portion 211. As a result, the main unit 4 grips the guide rail 2 (or its guide portion 211) without falling off the guide rail 2.

[0037] The lifting device 5 is installed in the upper part of the elevator shaft 1 (preferably at the very top of the elevator shaft 1). The lifting device 5 is an electrically operated lifting device, and a commercially available product is used. Electrically operated lifting devices include hoists, winches, cranes, and chain blocks. The lifting device 5 is not limited to any of these, and an appropriate one can be adopted.

[0038] An upper limit position detection object 10 is installed in the upper part of the elevator shaft 1 (preferably, at the very top of the elevator shaft 1, near the upper end of the uppermost guide rail 2), and a lower limit position detection object 11 is installed in the lower part of the elevator shaft 1 (preferably, at the very bottom of the elevator shaft 1, near the lower end of the lowest guide rail 2). The objects 10 and 11 are fixed to fixed parts such as the guide rails 2, beams, frames, or brackets in the elevator shaft 1 using fasteners. The objects 10 and 11 are installed on the movement path of the position detection unit 40 provided by the main unit 4, and are installed in order to operate the position detection unit 40. For example, the position detection unit 40 is a limit switch, and the objects 10 and 11 are limit switch cams that the limit switch contacts.

[0039] <Configuration of the centering device> As shown in Figure 3, the main unit 4A of the centering device 3A has a device base that is divided into two upper and lower device bases, comprising a lower device base 40A and an upper device base 41A. The lower device base 40A and the upper device base 41A are connected via a drive mechanism 42A. As an example, the drive mechanism 42A comprises a stepping motor, an eccentric cam, and a guide plate. The eccentric cam is fixed to the drive shaft of the stepping motor and inserted into a guide groove of the guide plate. When the rotation angle of the drive shaft of the stepping motor is changed, the angle of the eccentric cam is changed accordingly, thereby changing the position (and angle) of the guide plate on the horizontal plane. The stepping motor and eccentric cam are provided on either the lower device base 40A or the upper device base 41A, and the guide plate is provided on the other of the lower device base 40A or the upper device base 41A. As a result, the lower device base 40A is provided so that its position (and angle) in the horizontal plane can be changed relative to the upper device base 41A, and conversely, the upper device base 41A is provided so that its position (and angle) in the horizontal plane can be changed relative to the lower device base 40A. The lower guide body 43A is attached to the lower part of the lower device base 40A, and the upper guide body 43A is attached to the upper part of the upper device base 41A.

[0040] The main unit 4A includes, as functional parts, a fixing part 44A, a clamping part 45A, and a fastening part 46A.

[0041] The fixing part 44A is provided on the lower device base 40A and has the function of fixing the lower device base 40A so that it does not move in the horizontal plane. The fixing part 44A comprises an arm 440A and a coupling pin 441A. The arm 440A is rotatably (oscillately) attached at one end to the lower device base 40A directly or indirectly via a bracket. The rotational movement of the arm 440A is performed by a drive mechanism. As an example, the drive mechanism is configured to include an air cylinder as an air-driven actuator and an air compressor. The coupling pin 441A is provided at the other end of the arm 440A. The coupling pin 441A is inserted into a pin insertion hole 270a formed in the wall bracket 270 of the guide rail support 27 when the arm 440A is rotated to one side. A pair of arms 440A and coupling pins 441A are provided on the left and right sides, and correspondingly, a pair of pin insertion holes 270a are also provided on the left and right sides. When the two connecting pins 441A, 441A are inserted into the two pin insertion holes 270a, 270a, the lower device base 40A is fixed to the wall bracket 270 and becomes immobile in the horizontal plane. The pin insertion holes 270a are formed by drilling during the manufacturing of the wall bracket 270.

[0042] The clamp section 45A is provided on the upper device base 41A and has the function of clamping (gripping) the guide rail 2. The clamp section 45A is equipped with a pair of clamping claws. Each of the pair of clamping claws contacts the guide surface 211a of the guide section 211 of the guide rail 2 so as to be able to move toward and away from it. The opening and closing operation of the pair of clamping claws is performed by a drive mechanism. As an example, the drive mechanism is configured to include an air cylinder as an air-driven actuator and an air compressor. When the clamp section 45A is operated, the upper device base 41A firmly grips and fixes the guide rail 2 and becomes integrated with the guide rail 2.

[0043] The fastening section 46A is provided on the upper device base 41A and has the function of fastening the fixing device 272 to permanently fix the rail bracket 271 of the guide rail support 27 to the wall bracket 270. Specifically, the fastening section 46A is equipped with a nut runner, and the fixing device 272 is a combination of a bolt and nut (and washers, etc., if necessary). The nut runner is equipped with a motor and a socket. The rotational movement of the socket is performed by the motor. The nut runner is provided to be movable between a first position (lowered position) in which the socket engages with the nut, a second position (upper position) in which it is away from the nut and located directly above the nut, and a third position (retracted position) in which it does not interfere with the wall bracket 270 in the vertical direction. The movement of the nut runner is performed by a drive mechanism. As an example, the drive mechanism is equipped with a linear guide, an air cylinder as an air-driven actuator, and an air compressor. The air compressors for the fixing section 44A, clamp section 45A, and fastening section 46A are all shared by a single unit, but they may also be provided separately.

[0044] As shown in Figure 4, the main unit 4A further includes a position detection unit 47A and a position detection unit 48A as functional units.

[0045] The position detection unit 47A is provided on the lower device base 40A and has the function of detecting the wall bracket 270 of the guide rail support 27 during the movement of the main device 4A on the guide rail 2, that is, the function of detecting the support position of the guide rail 2 during the movement of the main device 4A on the guide rail 2, and the function of detecting the position (and angle) of the lower device base 40A on the horizontal plane relative to the wall bracket 270. The position detection unit 47A is equipped with a reflective laser displacement sensor. Two laser displacement sensors each measure the distance to the front end surface of the wall bracket 270. The other laser displacement sensor measures the distance to either the left or right side of the wall bracket 270.

[0046] The position detection unit 48A is provided on the upper device base 41A and has the function of detecting the position (and angle) of the upper device base 41A on the horizontal plane with respect to the vertical reference line 12 in the hoistway 1. The vertical reference line 12 is a piano wire stretched vertically from the top to the bottom of the hoistway 1 during elevator installation work. The position detection unit 48A is equipped with a transmissive laser displacement sensor. Two sets of laser displacement sensors measure the distance to the vertical reference line 12 in the left-right direction (parallel to the wall surface 1a of the hoistway 1). The other set of laser displacement sensors measures the distance to the vertical reference line 12 in the front-back direction (perpendicular to the wall surface 1a of the hoistway 1).

[0047] As shown in Figure 5, the control unit 49A of the main unit 4A controls the entire centering device 3A, including the operation and non-operation of the drive mechanism 42A, the fixed part 44A, the clamp part 45A, and the fastening part 46A. The control unit 49A includes a driver unit 490A for the drive mechanism 42A (motor), a driver unit 491A for the fixed part 44A (air cylinder), a driver unit 492A for the clamp part 45A (air cylinder), and a driver unit 493A for the fastening part 46A (air cylinder and motor).

[0048] Various switches are connected to the control unit 49A. The power on switch 494A is a switch that turns the power of the main unit 4A ON / OFF. The start switch 495A is a switch that starts automatic operation. The stop switch 496A is a switch that is effective in automatic operation mode and stops the movement of the main unit 4A. The lift switch 497A is a switch that is effective in manual operation mode and issues a hoisting command to the lifting machine 5. The lower switch 498A is a switch that is effective in manual operation mode and issues a lowering command to the lifting machine 5. The automatic / manual selector switch 499A is a switch that selects whether to set the main unit 4A to automatic operation mode or manual operation mode. Switches 494A to 499A are located on the control panel of the main unit 4A and are operated by the operator.

[0049] A transmitter 500A is connected to the control unit 49A. The transmitter 500A has the function of transmitting hoisting commands (and related signals) and lowering commands (and related signals) to the receiving unit 504 of the lifting machine 5. For example, the transmitter 500A is in the form of a transmitter.

[0050] The control unit 50 of the lifting machine 5 comprises a driver unit 500 for the motor 502 and a driver unit 501 for the brake 503. A receiving unit 504 is connected to the control unit 50. The receiving unit 504 has the function of receiving hoisting commands (and related signals) and lowering commands (and related signals) from the transmitting unit 500A. For example, the receiving unit 504 is in the form of a receiver. As mentioned above, if the lifting machine 5 is a commercially available product, the receiver is equipped with a plug compatible with the pendant switch mounting part of the lifting machine 5, and can be used without modifying the lifting machine 5 itself by removing the pendant switch from the lifting machine 5 and installing the receiver in its place.

[0051] When the control unit 50 receives a hoisting command (or related signal) or a lowering command (or related signal) from the transmitter unit 500A, it releases the brake 503 via the driver 501 and drives the motor 502 in forward or reverse direction via the driver 500 to hoist or lower the wire. When the control unit 50 no longer receives a hoisting command (or related signal) or a lowering command (or related signal), it stops driving the motor 502 via the driver 500 and activates the brake 503 via the driver 501. In other words, the lifting machine 5 is remotely controlled by the main unit 4A. Alternatively, the lifting machine 5 may be remotely controlled by receiving a hoisting command (or related signal) or a lowering command (or related signal) from a remote control.

[0052] <How to use the centering device (automatic operation mode)> Next, we will explain the procedure for setting up the alignment device 3A and the contents of the automatic operation mode. In automatic operation mode, the main unit 4A and the lifting machine 5 are linked via wireless communication, and the main unit 4A automatically moves while aligning and fixing the guide rail 2. In manual operation mode, an operator rides in a gondola and moves with the main unit 4A, operating the control panel of the main unit 4A to align and fix the guide rail 2.

[0053] (Step 1) The worker moves to the top of the elevator shaft 1 by gondola and installs the lifting machine 5 equipped with a wireless receiver 504 and the object 10 for detecting the upper limit position at the top of the elevator shaft 1.

[0054] (Step 2) The worker moves to the lowest point of the elevator shaft 1 by gondola.

[0055] (Step 3) The operator connects an external power supply to the main unit 4A. Note that if the power supply (battery) built into the main unit 4A is used, step 3 is unnecessary.

[0056] (Step 4) The worker lowers the wire from the lifting machine 5, attaches the hook to the main unit 4A, and then brings the main unit 4A into the elevator shaft 1.

[0057] (Step 5) The worker installs the main unit 4A on the lowest guide rail 2 and the object 11 for detecting the lower limit position at the lowest point inside the elevator shaft 1.

[0058] (Step 6) The operator presses the start switch 495A. This starts automatic operation. Alternatively, the start switch 495A may be located on the remote control instead of on the control panel of the main unit 4A, and automatic operation may be started by pressing the start switch on the remote control. In this case, a transceiver unit is used instead of the transmitter unit 500A.

[0059] (Operation 7) The main unit 4A issues a hoisting command (up command) to the lifting machine 5 and raises itself until the position detection unit 47A detects the wall bracket 270 of the second guide rail support 27 from the bottom.

[0060] (Operation 8) When the main unit 4A detects the wall bracket 270, it stops issuing hoisting commands to the lifting machine 5, which it had been doing until then, and stops itself.

[0061] (Operation 9) The main unit 4A uses the position detection unit 47A to measure the distance to the wall bracket 270 in the horizontal plane. If the position of the coupling pin 441A of the fixing unit 44A is misaligned with respect to the pin insertion hole 270a of the wall bracket 270, the drive mechanism 42A is driven to correct the position (and angle) of the lower unit base 40A to eliminate the misalignment.

[0062] (Operation 10) The main unit 4A activates the fixing part 44A, inserting the coupling pin 441A into the pin insertion hole 270a, thereby fixing the lower unit base 40A so that it does not move in the horizontal plane.

[0063] (Operation 11) The main unit 4A activates the clamp section 45A and clamps the guide rail 2 with the upper unit base 41A.

[0064] (Operation 12) The main unit 4A uses the position detection unit 48A to measure the distance to the vertical reference line 12 in the horizontal plane. If it deviates from the specified value, it drives the drive mechanism 42A to correct the position (and angle) of the upper unit base 41A and eliminate the deviation. At this time, the guide rail 2, which is clamped to the clamp unit 45A, moves together and is centered.

[0065] (Operation 13) The main unit 4A activates the fastening part 46A and fastens the fixing device 272 to permanently fix the rail bracket 271 to the wall bracket 270.

[0066] (Operation 14) The main unit 4A sets the fastening portion 46A, the fixing portion 44A, and the clamp portion 45A to a non-operating mode.

[0067] The main unit 4A performs centering and final fixing up to the uppermost guide rail 2 by repeating operations 7 to 14.

[0068] When the main unit 4A detects the object 10 for upper limit position detection, it stops issuing hoisting commands to the lifting machine 5, which it had been issuing until then, and stops itself. Alternatively, it may change to a lowering command (downward command) and lower itself to the lower limit position.

[0069] With the above steps, the alignment and final fixing of one row of guide rails 2 is completed. To align and final fix another row of guide rails 2, the worker simply switches the main unit 4A and repeats the same process.

[0070] <Configuration of the cleaning device> The main unit of the cleaning device comprises a spraying unit and a removal unit as its functional components.

[0071] As shown in Figure 6, the spray unit 40B includes a nozzle 400B positioned so that its nozzle faces the guide portion 211 of the guide rail 2. In operation mode, it has the function of spraying a chemical solution (e.g., cleaning solution) onto the surface of the guide portion 211 by supplying the chemical solution to the nozzle 400B. A supply unit 401B is connected to the nozzle 400B. The supply unit 401B consists of a tube as a conduit and a pump as an actuator, and supplies the chemical solution to the nozzle 400B from a tank that holds a sufficient amount of chemical solution so that frequent replenishment of the chemical solution is not necessary.

[0072] As shown in Figure 7, the removal unit 41B is equipped with a scraper 410B that can move toward and away from the surface of the guide portion 211 of the guide rail 2. In the operating mode, the scraper 410B is brought into contact with the surface of the guide portion 211, and has the function of removing deposits from the surface of the guide portion 211 as the main unit 4B moves. Each of the two scrapers 410B can move toward and away from the guide surface 211a of the guide portion 211. The other scraper 410B can move toward and away from the tip surface 211b of the guide portion 211. The movement of the scraper 410B is performed by a drive mechanism. The drive mechanism is a mechanism that moves the scraper 410B between an operating mode in which it is in contact with the surface of the guide portion 211 and a non-operating mode in which it is separated from the surface of the guide portion 211. As an example, the drive mechanism is configured to include a linear guide, an air cylinder as an air-driven actuator, and an air compressor.

[0073] As shown in Figure 8, the control unit 42B of the main unit 4B controls the entire cleaning device 3B, including the operation and deoperation of the spray unit 40B and the removal unit 41B. The control unit 42B includes a driver unit 420B for the spray unit 40B (pump) and a driver unit 421B for the removal unit 41B (air cylinder).

[0074] Various switches are connected to the control unit 42B. The power on switch 422B is a switch that turns the power of the main unit 4B ON / OFF. The start switch 423B is a switch that starts automatic operation. The stop switch 424B is a switch that is effective in automatic operation mode and stops the movement of the main unit 4B. The lift switch 425B is a switch that is effective in manual operation mode and issues a hoisting command to the lifting machine 5. The lower switch 426B is a switch that is effective in manual operation mode and issues a lowering command to the lifting machine 5. The automatic / manual selector switch 427B is a switch that selects whether to set the main unit 4B to automatic operation mode or manual operation mode. The spray ON / OFF selector switch 428B is a switch that is effective in manual operation mode and selects whether to set the spray unit 40B to operation mode or non-operation mode. The scraper ON / OFF switch 429B is a switch that is active in manual operation mode and selects whether to activate or deactivate the removal unit 41B. The spray addition ON / OFF switch 430B is a switch that is active in automatic operation mode and selects whether to activate the spray unit 40B when the removal unit 41B is in operation mode. Switches 422B to 430B are located on the control panel of the main unit 4B and are operated by the operator.

[0075] A transmitter 431B is connected to the control unit 42B. The transmitter 431B has the function of transmitting hoisting commands (and related signals) and lowering commands (and related signals) to the receiving unit 504 of the lifting machine 5. For example, the transmitter 431B is in the form of a transmitter.

[0076] The control unit 50 of the lifting machine 5 is as described in the above section <Configuration of the centering device>.

[0077] <How to use the cleaning device (automatic operation mode)> Next, the procedure for setting up the cleaning device 3B and the details of the automatic operation mode will be explained. In automatic operation mode, the main unit 4B and the lifting machine 5 are linked via wireless communication, and the main unit 4B automatically moves while cleaning the surface of the guide section 211 of the guide rail 2. In manual operation mode, an operator rides in a gondola and moves with the main unit 4B, operating the control panel of the main unit 4B to clean the surface of the guide section 211.

[0078] (Step 1) The worker moves to the top of the elevator shaft 1 by gondola and installs the lifting machine 5 equipped with a wireless receiver 504 and the object 10 for detecting the upper limit position at the top of the elevator shaft 1.

[0079] (Step 2) The worker moves to the lowest point of the elevator shaft 1 by gondola.

[0080] (Step 3) The operator connects an external power supply to the main unit 4B. Note that if the power supply (battery) built into the main unit 4B is used, step 3 is unnecessary.

[0081] (Step 4) The worker lowers the wire from the lifting machine 5, attaches the hook to the main unit 4B, and then brings the main unit 4B into the elevator shaft 1.

[0082] (Step 5) The worker installs the main unit 4B on the lowest guide rail 2 and places the object 11 for detecting the lower limit position at the lowest point inside the elevator shaft 1.

[0083] (Step 6) The worker replenishes the chemical solution (by attaching the tank).

[0084] (Step 7) The operator presses the start switch 423B. This starts automatic operation. Alternatively, the start switch 423B may be located on the remote control instead of on the control panel of the main unit 4B, and automatic operation may be started by pressing the start switch on the remote control. In this case, a transceiver unit is used instead of the transmitter unit 431B.

[0085] (Operation 8) The main unit 4B issues a hoisting command to the lifting machine 5 and raises itself to the detected position (upper limit position) of the object 10 for upper limit position detection. During this time, the main unit 4B puts the removal unit 41B into operation mode. However, the removal unit 41B may remain in non-operation mode.

[0086] (Operation 9) When the main unit 4B detects the object 10 for upper position detection, it stops issuing a hoisting command to the lifting machine 5, changes to a lowering command, and reverses its own movement from upward to downward. At this time, the main unit 4B puts the removal unit 41B into non-operating mode and the injection unit 40B into operating mode. The forward journey begins from here.

[0087] (Operation 10) The main unit 4B lowers itself to the detection position (lower limit position) of the lower limit position detection target object 11 while spraying the chemical solution.

[0088] (Operation 11) When the main unit 4B detects the object 11 for lower limit position detection, it stops issuing lowering commands to the lifting machine 5, which it had been doing until then, and stops itself. At this time, the main unit 4B puts the injection unit 40B into non-operation mode.

[0089] (Operation 12) After a certain period of time (for example, 1 minute), the main unit 4B issues a hoisting command to the lifting machine 5 and raises itself. At this time, the main unit 4B activates the removal unit 41B. The return journey begins from here. The reason for waiting a certain period of time is to allow the viscosity of the rust-preventive oil to decrease after the chemical solution is sprayed.

[0090] (Operation 13) The main unit 4B raises itself to the upper limit position while bringing the scraper 410B into contact with the guide rail 2. If the spray ON / OFF switch 430B is ON, the chemical solution is also sprayed.

[0091] (Operation 14) When the main unit 4B detects the object 10 for upper limit position detection, it stops issuing hoisting commands to the lifting machine 5, which it had been issuing until then, and stops itself. At this time, the main unit 4B puts the removal unit 41B into non-operating mode. Alternatively, it may change to a lowering command and lower itself to the lower limit position.

[0092] This completes the cleaning of one row of guide rails 2. To clean another row of guide rails 2, the worker switches the main unit 4B and repeats the same process.

[0093] <Configuration of the ground joint device> As shown in Figure 9, the main unit 4C of the lapping device 3C comprises a device base 40C and a movable base 42C. The movable base 42C is mounted on the device base 40C so as to be able to move up and down within a predetermined range while being guided by a vertical frame composed of guide bodies such as linear guides. The up and down movement of the movable base 42C is performed by a drive mechanism. As an example, the drive mechanism comprises a ball screw and a motor 400C. The ball screw is rotatably mounted on the device base 40C so as to have its axis aligned in the vertical direction and is screwed into the movable base 42C. The motor 400C is mounted on the device base 40C and imparts rotation to the ball screw.

[0094] The main unit 4C includes a sliding section 43C as a functional section. As shown in Figure 10(a), the sliding section 43C is equipped with a rotating grinding wheel 430C that can move toward and away from the surface of the guide section 211 of the guide rail 2. In the operating mode, by bringing the rotating grinding wheel 430C into contact with the surface of the guide section 211, it has the function of polishing the surface of the guide section 211 to eliminate steps as the movable base 42C moves upward, downward, or up and down. Two rotating grinding wheels 430C each make contact with the guide surface 211a of the guide section 211 in a manner that allows them to move toward and away from it. Another rotating grinding wheel 430C makes contact with the tip surface 211b of the guide section 211 in a manner that allows them to move toward and away from it. The movement of the rotating grinding wheels 430C is performed by a drive mechanism. The drive mechanism is a mechanism that moves the rotating grinding wheel 430C between an operating mode in which it is in contact with the surface of the guide portion 211 and a non-operating mode in which it is separated from the surface of the guide portion 211. As an example, the drive mechanism is configured to include a linear guide, an air cylinder as an air-driven actuator, and an air compressor. The rotation of the rotating grinding wheel 430C is performed by a motor.

[0095] As shown in Figure 10(b), the main unit 4C further includes a step detection unit 44C as a functional unit. The step detection unit 44C has the function of detecting steps that occur between the two guide surfaces 211a, 211a and the two end surfaces 211b, 211b of the two guide sections 211, 211 at the connecting portion at both ends of the upper and lower guide rails 2, 2 during the movement stroke of the main unit 4C on the guide rail 2. The step detection unit 44C is equipped with a reflective laser displacement sensor. Two laser displacement sensors each measure the distance to the guide surface 211a. The other laser displacement sensor measures the distance to the end surface 211b. If a step occurs, the measured value changes discontinuously, so the step can be detected.

[0096] As shown in Figure 11, the control unit 45C of the main unit 4C controls the entire lapping device 3C, including the operation and non-operation of the lapping section 43C. The control unit 45C includes a driver unit 450C for the motor 400C and a driver unit 451C for the lapping section 43C (its air cylinder and motor).

[0097] Various switches are connected to the control unit 45C. The power on switch 452C is a switch that turns the power of the main unit 4C ON / OFF. The start switch 453C is a switch that starts automatic operation. The stop switch 454C is a switch that is effective in automatic operation mode and stops the movement of the main unit 4C. The lift switch 455C is a switch that is effective in manual operation mode and issues a hoisting command to the lifting machine 5. The lower switch 456C is a switch that is effective in manual operation mode and issues a lowering command to the lifting machine 5. The upward movement switch 457C is a switch that is effective in manual operation mode and issues an upward movement command to the motor 400C. The downward movement switch 458C is a switch that is effective in manual operation mode and issues a downward movement command to the motor 400C. The automatic / manual changeover switch 459C is a switch that selects whether to put the main unit 4C into automatic operation mode or manual operation mode. The 460C ON / OFF switch for the lap joint is a switch that is active in manual operation mode and selects whether the lap joint 43C is in operation mode or deoperated mode. Switches 452C to 460C are located on the control panel of the main unit 4C and are operated by the operator.

[0098] A transmitter 461C is connected to the control unit 45C. The transmitter 461C has the function of transmitting hoisting commands (and related signals) and lowering commands (and related signals) to the receiving unit 504 of the lifting machine 5. For example, the transmitter 461C is in the form of a transmitter.

[0099] The control unit 50 of the lifting machine 5 is as described in the above section <Configuration of the centering device>.

[0100] <How to use the jointing device (automatic operation mode)> Next, the procedure for setting up the lapping device 3C and the details of the automatic operation mode will be explained. In the automatic operation mode, the main unit 4C and the lifting machine 5 are linked by wireless communication, and the main unit 4C automatically moves while lapping the surface of the guide section 211 of the guide rail 2. In the manual operation mode, an operator rides in a gondola and moves with the main unit 4C, operating the control panel of the main unit 4C to lapping the surface of the guide section 211.

[0101] (Step 1) The worker moves to the top of the elevator shaft 1 by gondola and installs the lifting machine 5 equipped with a wireless receiver 504 and the object 10 for detecting the upper limit position at the top of the elevator shaft 1.

[0102] (Step 2) The worker moves to the lowest point of the elevator shaft 1 by gondola.

[0103] (Step 3) The operator connects an external power supply to the main unit 4C. Note that if the power supply (battery) built into the main unit 4C is used, step 3 is unnecessary.

[0104] (Step 4) The worker lowers the wire from the lifting machine 5, attaches the hook to the main unit 4C, and then brings the main unit 4C into the elevator shaft 1.

[0105] (Step 5) The worker installs the main unit 4C on the lowest guide rail 2 and the object 11 for detecting the lower limit position at the lowest point inside the elevator shaft 1.

[0106] (Step 6) The operator presses the start switch 453C. This starts automatic operation. Alternatively, the start switch 453C may be located on the remote control instead of on the control panel of the main unit 4C, and automatic operation may be started by pressing the start switch on the remote control. In this case, a transceiver unit is used instead of the transmitter unit 461C.

[0107] (Operation 7) The main unit 4C issues a hoisting command to the lifting machine 5 and raises itself until the step detection unit 44C detects a step on the guide surface 211a of the guide portion 211 of the guide rail 2.

[0108] (Operation 8) When the main unit 4C detects a step, it stops issuing hoisting commands to the lifting machine 5, which it had been doing until then, and stops itself. At this time, the movable base 42C is positioned in the middle of its vertical stroke range.

[0109] (Operation 9) The main unit 4C, after setting the sliding joint 43C to operating mode, issues a single reciprocating movement command (up command → down command → up command, or down command → up command → down command) to the motor 400C. Alternatively, multiple reciprocations (two, three, etc.) may be performed. Alternatively, the reciprocating motion may be repeated until the step detection unit 44C no longer detects a step. As a result, the rotating grinding wheel 430C grinds (polishes) the surface of the guide portion 211 of the guide rail 2 within a vertical stroke range that spans the joints of the connecting portions at both ends of the upper and lower guide rails 2, 2.

[0110] (Operation 10) The main unit 4C puts the sliding joint 43C into a non-operating mode and stops issuing movement commands to the motor 400C when the movable base 42C is positioned in the middle of its vertical stroke range.

[0111] The main unit 4C performs sliding adjustments up to the uppermost guide rail 2 by repeating operations 7 to 9.

[0112] When the main unit 4C detects the object 10 for upper limit position detection, it stops issuing hoisting commands to the lifting machine 5, which it had been issuing until then, and stops itself. Alternatively, it may change to a lowering command and lower itself to the lower limit position.

[0113] This completes the lapping of one row of guide rails 2. To lapping another row of guide rails 2, the operator switches the main unit 4C and repeats the same process.

[0114] As described above, according to the installation support device 3 of this embodiment, a lifting machine 5 that suspends and supports the main unit 4 is used as the drive source for moving the main unit 4, and the lifting machine 5 is remotely controlled by the control unit of the main unit 4. As a result, the overall weight of the main unit 4 does not increase, and operation of the lifting machine 5 by the worker is not required. Therefore, according to the installation support device 3 of this embodiment, it is possible to reduce the burden on the worker through weight reduction and achieve complete automation.

[0115] It should be noted that the present invention is not limited to the embodiments described above, and various modifications are possible without departing from the spirit of the invention.

[0116] The above embodiment describes an example of processing the guide rail 2 for the cage. However, the present invention is not limited thereto. It goes without saying that the installation support device can also be used when processing the guide rail for the counterweight.

[0117] In the above embodiment, there is one type each of hoisting command and lowering command for the lifting machine 5, and one type each of lifting speed and lowering speed. However, the present invention is not limited thereto. There may be two types of commands, low speed and high speed, or even three or more different speed commands.

[0118] In the above embodiment, the main unit 4 and the lifting machine (sub-unit) 5 are used in a one-to-one ratio. However, the present invention is not limited to this. It is also possible to attach the main unit 4 to each of the two rows of guide rails 2,2, connect the two main units 4,4 with a connecting member to form a single unit, attach a hook to the connecting member (in the center), and use one lifting machine 5 to raise and lower the two main units 4,4, thereby processing the two rows of guide rails 2,2 simultaneously. In this case, not only can the processing time be shortened and processing costs be reduced, but there is also the effect of being able to use the lifting machine that is already installed between the guide rails 2,2 instead of preparing and installing a lifting machine for the main unit 4.

[0119] In the above embodiment, a limit switch 40 that contacts a detection target (limit switch cam 10, 11) is used as a detection unit to detect when the main unit 4 has reached the upper limit position and the lower limit position during its movement on the guide rail 2. However, the present invention is not limited to this. Various configurations can be adopted for the detection unit, including the following configuration. Note that, as described in the following paragraph and the paragraph after that, in the case of an operating method in which the main unit does not move to the upper limit position or the lower limit position, such as when processing is terminated at a processing location, the detection unit is unnecessary. The main unit is equipped with detection means such as sensors (photoelectric sensors, etc.) that detect objects to be detected without contact. The main unit is equipped with imaging means such as a camera and captures images of specific objects at the top and bottom of the elevator shaft (including objects installed at the top and bottom, as well as the ceiling and floor surfaces themselves). The control unit of the main unit determines the upper and lower limits based on the captured images. The main unit is equipped with a distance measuring means such as a laser rangefinder, and measures the distance to the ceiling and floor surfaces using a laser. The control unit of the main unit compares the measurement results with predetermined values ​​to determine the upper and lower limits. The main unit is equipped with a timing device that measures the movement time of the main unit, and the control unit of the main unit compares the timing result with predetermined values ​​to determine the upper and lower limit positions. The main unit (specifically its guide body (roller guide)) is equipped with an encoder, and the control unit of the main unit calculates the travel distance to determine the upper and lower limits. (When the lifting machine has a transmitting unit and the main unit has a receiving unit) The control unit of the main unit obtains the activation signal from the overwinding switch of the lifting machine and determines the upper limit position. (When the lifting machine has a transmitting unit and the main unit has a receiving unit) The lifting machine is equipped with an encoder, and the control unit of the main unit obtains the value of the lifting machine's encoder, calculates the distance traveled, and determines the upper and lower limits.

[0120] In the above embodiment, a laser displacement sensor 47A that detects the wall bracket 270 of the guide rail support 27 is used as a detection unit to detect when the main unit 4 has reached the support position of the guide rail 2 during its movement on the guide rail 2. However, the present invention is not limited to this. Various configurations can be adopted for the detection unit, including the following configurations. • The main unit is equipped with detection means such as sensors for detecting rail brackets. The control unit of the main unit stores information about the number of support points for the guide rail in advance, and terminates the alignment process when that number is reached. The control unit of the main unit stores information about the total length of one row of guide rails in advance. When the cumulative distance traveled by the main unit (the travel speed is known from the specifications of the lifting machine, and the travel distance is calculated from the travel speed and the measured value of the travel time) reaches the total length minus the margin, the alignment process is terminated. The control unit of the main unit stores the position information of the wall bracket or rail bracket in advance, and determines the stopping position based on this position information.

[0121] In the above embodiment, a laser displacement sensor 44C is used as a detection unit to detect when the main unit 4 reaches a position on the surface of the guide portion 211 of the guide rail 2 during its movement along the guide rail 2 where a step has occurred. However, the present invention is not limited to this. Various configurations can be adopted for the detection unit, including the following configurations. • The main unit is equipped with detection means such as sensors to detect the position of the joints in the guide rails. • The main unit is equipped with detection means such as sensors that detect connecting materials (spanner plates) or fasteners for connecting materials (spanner bolts). The control unit of the main unit stores information about the number of joints in the guide rail in advance, and when that number is reached, the fitting process is terminated. The control unit of the main unit stores information about the total length of one row of guide rails in advance. When the cumulative distance traveled by the main unit (the travel speed is known from the specifications of the lifting machine, and the travel distance is calculated from the travel speed and the measured value of the travel time) reaches the total length minus the allowance, the fitting process is terminated. The control unit of the main unit stores the position information of the guide rail joints in advance, and determines the stopping position based on this position information. The control unit of the main unit stores information regarding the length and order of each guide rail in a row of guide rails in advance, and determines the stopping position based on that information.

[0122] In the centering device 3A and lapping device 3C of the above embodiment, the processing (centering process and lapping process) is performed during the upward stroke as the main device 4 (4A, 4C) moves toward the upper limit position. However, the present invention is not limited thereto. The processing may also be performed during the downward stroke as the main device moves toward the lower limit position.

[0123] In the cleaning device 3B of the above embodiment, from the viewpoint of the form of the scraper 410B, the forward path is set to descend and the return path to ascend, with the spraying process performed during the descending process and the removal process performed during the ascending process. However, the present invention is not limited thereto. The forward path may be set to ascend and the return path to descend, with the spraying process performed during the ascending process and the removal process performed during the descending process.

[0124] In the above embodiment, the lapping process is performed after the cleaning process. However, the present invention is not limited thereto. If there is no problem with the step detection accuracy, the lapping process may be performed before the cleaning process.

[0125] In the above embodiment, the grinding process is performed only on the joints of the guide rails 2. However, the present invention is not limited thereto. As described in Patent Document 3 above, the grinding process of the guide rails may be performed over the entire length or nearly the entire length of a row of guide rails. In this case, the automatic operation mode is the same as the automatic operation mode for the cleaning process, which is for the forward journey only, one round trip, or two or more round trips.

[0126] In the above embodiment, the installation support device consists of three types of devices. However, the present invention is not limited thereto. Various devices can be used as the installation support device, including the following devices. A device that reduces the step height at the joint of a guide rail by inserting a spacer on the back or moving the guide rail within the clearance between the tenon and groove. • A device for comprehensively inspecting the installation accuracy and surface condition of guide rails. • A device for photographing the conditions inside the elevator shaft during or after installation work.
