Abstract

[Problem] To easily and quickly transport a control panel when renovating an elevator. [Solution] An upper handle 300 is attached to the top of the control panel 106 using a hanging bracket 204 used to prevent the control panel 106 from falling over, and a lower handle 400 is attached to the bottom of the control panel 106 using a fixing bolt 601 used to fix the position of the control panel 106, and the control panel 106 is lifted and moved while a worker 600 holds the upper handle 300 and another worker 600 holds the lower handle 400. This makes it possible to transport the control panel 106 without using heavy machinery such as a crane or lifting the control panel 106 directly by hand, which is heavy and difficult to hold, so that the control panel 106 can be easily and quickly transported when renovating an elevator 100.

Description

This invention relates to a control panel transport aid used to transport elevator control panels and a method for transporting control panels.

Traditionally, when renovating elevator facilities in a multi-story building, the elevator shaft is often reused and all of the components that make up the elevator are replaced. Specifically, the elevator car and the drive mechanism, including the hoist that raises and lowers the car, are replaced.

When replacing an elevator control panel, if the type of programming language or writing method used to write the control programs for each component is different between the old and new control panels, the old components controlled by the old control panel will not be able to understand the control signals from the new control panel. For this reason, in the past, when replacing a control panel, in addition to replacing the old control panel, all of the old components controlled by the old control panel were replaced.

Thanks to recent technological improvements, control panels that use new technology to control elevators (new control panels) have functions and performance that are far superior to existing control panels (old control panels). However, when replacing a control panel, if all of the old components controlled by the old control panel are replaced in addition to the old control panel, the cost of renovation increases. For this reason, when renovating elevators, there is a high demand for only the control panel, where the old control panel is replaced with a new one.

In light of this background, in the past, in order to reduce the costs of renewal, when a user requested a renewal, for example, to replace an old control panel with a new one, there was a technique for realizing the renewal of only the control panel or only some of the old components, rather than a renewal that involved replacing all of the old components, taking into consideration that the existing (remaining) components that were not replaced (hereinafter referred to as "old components") would not be able to understand the control signals from the new control panel.

Specifically, for example, when replacing an old control panel with a new one, a signal conversion device that converts the signal output by the old component into another signal that has the same meaning as the old signal and can be understood by the new control panel is connected between the new control panel and the old component, and then at least one of the old components is replaced with a new component that outputs a signal that can be understood by the new control panel (for example, see Patent Document 1 below).

However, because the control panel is heavy, it takes time and effort to transport it, and even replacing just the control panel takes a certain amount of time, which creates an obstacle to speeding up elevator renovations.

The purpose of this invention is to provide a control panel transport aid and a control panel transport method that can easily and quickly transport a control panel when renovating an elevator, in order to solve the problems associated with the conventional technology described above.

In order to solve the above problems and achieve the objective, the control panel transport support device of the present invention is characterized by comprising: a fixed member having a through hole for a hanging hardware that can be passed through both the mounting hole of the hanging hardware used to hang and fix the elevator control panel when placed opposite the mounting hole of the hanging hardware; and a handle connected to the fixed member.

The control panel transport support device according to the present invention is characterized by comprising a fixed member having a bolt through hole through which the fixing bolt can pass together with the mounting hole of the fixing bolt when the fixed member is positioned opposite the mounting hole of the fixing bolt used to fix the elevator control panel to the stand or floor surface, and a handle connected to the fixed member.

The method for transporting a control panel according to the present invention is characterized in that a first control panel transport support tool is attached to the top surface of the control panel, the first control panel transport support tool being arranged opposite the mounting hole of a hanging bracket used to hang and fix the elevator control panel, the hanging bracket being arranged opposite the mounting hole of the hanging bracket, the hanging bracket being arranged opposite the mounting hole of the hanging bracket, the hanging bracket being arranged opposite the mounting hole of the hanging bracket, the hanging bracket being arranged opposite the mounting hole of the bolt used to fix the control panel to the frame, the second control panel transport support tool being arranged opposite the mounting hole of the bolt used to fix the control panel to the frame, the second control panel transport support tool being arranged opposite the mounting hole of the bolt used to fix the control panel to the frame, the bolt ...

Below, a preferred embodiment of the control panel transport aid and control panel transport method of the present invention will be described in detail with reference to the attached drawings. The control panel transport aid of the present invention is used to transport elevator control panels.

(Elevator configuration)
First, the configuration of an elevator will be described. Fig. 1 is an explanatory diagram showing the configuration of an elevator. In Fig. 1, the elevator 100 can be realized by, for example, a rope-type (traction-type) elevator. The elevator 100 is installed in, for example, a building such as a multi-story building.

The elevator 100 is equipped with a car (passenger car) 101 for carrying people and goods. One car 101 is provided for each elevator 100. The car 101 is provided in a hoistway (not shown) that passes through each floor of the building in the vertical direction, i.e., along the direction of movement of the car 101.

The elevator shaft is provided with guide rails (not shown) on the sides to guide the elevator position of the car 101. The elevator shaft is also provided with a shock absorber 102 at the bottom to cushion the impact if the car 101 falls and hits the bottom of the elevator shaft. The shock absorber 102 may be a spring type shock absorber 102 that uses the elastic force of a spring to cushion the impact, or an oil-filled type shock absorber 102 that uses hydraulic resistance to cushion the impact. The shock absorber 102 may also be provided on the ceiling surface of the elevator shaft.

The cage 101 is connected to one end of a rope 103. The rope 103 is hung in a bucket-like manner on a pulley (not shown) and a hoist (traction machine) 104, and the other end is connected to a counterweight 105. Specifically, the rope 103 can be realized by, for example, a steel wire.

The hoist 104 in the rope-type elevator 100 is installed, for example, in a machine room provided at the top of the elevator 100. The hoist 104 can be provided at the top of the elevator 100 regardless of whether or not there is a machine room. Alternatively, if the elevator 100 is a type that does not have a machine room, the hoist 104 may be provided at the bottom of the elevator 100.

The hoist 104 is controlled, for example, using an inverter, and is driven and controlled by a control panel 106 so as to stop rotation at the floor where the car 101 is to be stopped. In a rope-type elevator 100, the car 101 is raised and lowered by utilizing the frictional force (traction) between the rope 103 and the pulley, which is generated by driving the hoist 104.

The hoist 104 is equipped with an encoder (not shown), and the control panel 106 can determine the rotational speed and rotational position of the hoist 104 based on the output signal from the encoder. The encoder may be, for example, an absolute encoder or an incremental encoder. The encoder may be provided when the elevator 100 is installed, or may be added later after installation.

The elevator 100 also includes an electromagnetic brake 107, a governor machine 108, a limit switch 109, and the like. The electromagnetic brake 107 includes a coil, and is driven and controlled by a control panel 106 to stop the rotation of the hoisting machine 104 by utilizing the electromagnetic force generated by passing electricity through the coil. The electromagnetic brake 107 can maintain the state in which the rotation of the hoisting machine 104 is stopped.

The electromagnetic brake 107 stops the rotation of the hoist 104 when the power supply is stopped due to a power outage or the like. Specifically, the electromagnetic brake 107 may be, for example, a non-excitation type electromagnetic brake 107 that operates by spring force to stop the rotation of the hoist 104 when the current to the coil is cut off due to a power outage or the like.

The governor 108 detects when the cage 101 is speeding up. The governor 108 can be realized, for example, by a centrifugal governor equipped with a governor rope 108a, a governor pulley 108b, and a rotor (not shown). In such a governor 108, the governor rope 108a is linked to the operation of the cage 101. The governor pulley 108b rotates in conjunction with the operation of the governor rope 108a.

The rotor operates according to the rotation speed of the governor pulley 108b, i.e., the magnitude of the centrifugal force caused by the rotation of the governor pulley 108b. Specifically, the rotor operates to open to the outer periphery of the governor pulley 108b when the rotation speed of the governor pulley 108b is high, and operates to close to the inner periphery of the governor pulley 108b when the rotation speed of the governor pulley 108b is low.

The limit switch 109 is equipped with a switch lever (not shown) that switches between supplying and cutting off power to the hoist 104. The switch lever is normally positioned in a position that supplies power to the hoist 104, and when biased by the rotor of the speed governor 108, it is displaced to a position that cuts off the supply of power to the hoist 104.

The rotor of the speed governor 108 biases the switch lever so that, when the ascending or descending speed of the cage 101 reaches a certain speed or higher relative to the rated speed, the switch lever is displaced to a position that cuts off the supply of power to the hoist 104. This allows the operation of the hoist 104 to be stopped and the cage 101 to be stopped when the cage 101 exceeds its speed limit.

The elevator 100 may further include an emergency stop device. The emergency stop device forcibly stops the movement of the car 101 when the movement of the car 101 and the movement of the governor rope 108a differ, i.e., when the car 101 is moving even though the governor rope 108a has stopped. The emergency stop device can be easily realized using various known technologies, so a description thereof will be omitted.

The cage 101 is equipped with a door 101a. The cage 101 is also equipped with a motor (not shown) that opens and closes the door 101a, a door opening/closing sensor (not shown) that detects the open/closed state of the door 101a, and an operation panel 101b. The motor that opens and closes the door 101a is driven and controlled by a control panel 106 to open and close the door 101a.

The output of the door opening/closing sensor changes depending on whether the door 101a or the door 110a is open or closed, depending on the state of the safety shoe located between the doors 101a and 110a. The door opening/closing sensor can be realized, for example, by a microswitch or a photoelectric sensor. The door opening/closing sensor is connected to the control panel 106 via a wire, and the signal output from the door opening/closing sensor is input to the control panel 106 via the wire.

Doors 110a are provided at positions (landings) 110 in the elevator shaft that correspond to each floor. The doors 110a at the landings 110 are locked by a device called an interlock (not shown). The interlock engages with the opening and closing mechanism of the door 101a of the car 101 to release the lock only when the motor of the car 101 is driven after the elevator 100 has arrived at a stopping floor. This allows only the door 110a at the landing 110 on the floor where the car 101 is located to be opened and closed in conjunction with the doors 110a provided at each floor.

In addition, at positions (landings) 110 in the elevator shaft corresponding to each floor, a plate (not shown) is provided for detecting the position of the car 101. A plurality of plates are provided in the longitudinal direction of the elevator shaft, i.e., in the vertical direction. The car 101 is provided with a car position detection sensor 101c for detecting the position of the car 101 using the plate.

The cage position detection sensor 101c is provided, for example, on the outside of the cage 101, on the ceiling or wall of the cage 101. The cage position detection sensor 101c has a light-emitting element and a light-receiving element provided in a position opposite the light-emitting element. The cage position detection sensor 101c outputs a signal according to the light-receiving state of the light-receiving element. Specifically, as the cage 101 moves, the cage position detection sensor 101c outputs different signals to the control panel 106 when a plate is positioned between the light-emitting element and the light-receiving element in the cage position detection sensor 101c and when the light-receiving element receives light emitted by the light-emitting element.

The plate is provided in a position that blocks light between the light-emitting element and the light-receiving element in the car position detection sensor 101c, for example, when the car 101 is located at the landing position (landing 110) on each floor. The plate may also be provided in a position that blocks light between the light-emitting element and the light-receiving element in the car position detection sensor 101c, for example, when the car 101 passes a position that is a predetermined distance away from the position where the car 101 stops on each floor. This makes it possible to identify the position of the car 101 before it reaches the destination floor.

Each platform 110 is provided with an operation panel 111 equipped with a platform call button 111a, a display 111b that displays the floor on which the car 101 is located, and the like. Each operation panel 111 is equipped with a control board 111c for the operation panel 111, and is connected to the control panel 106 via the control board 111c.

The operation panel 101b, various sensors including the car position detection sensor 101c and the door opening/closing sensor, the hoist 104, the electromagnetic brake 107, the speed governor 108, the limit switch 109, and the operation panel 111 (control board 111c) are all connected to the control panel 106 via cables 112.

(Appearance of control panel 106)
Next, the external appearance of the control panel 106 will be described. Fig. 2 is an explanatory diagram showing the external appearance of the control panel 106. As shown in Fig. 2, the control panel 106 has a rectangular parallelepiped housing 201. The housing 201 has a main body with an opening (not shown) on the front side, and a cover member 202 that closes the opening on the front side of the main body.

The housing 201 is fixed to, for example, a stand (not shown) installed in the machine room of the elevator 100. The cover member 202 is provided so as to be detachable from the housing 201. The cover member 202 has a gripping portion 203 that is gripped when attaching or detaching the cover member 202 to or from the housing 201.

The control panel 106 is provided with a hanging bracket (eye bolt) 204 on the top surface of the housing 201. The hanging bracket 204 has a ring-shaped head 204a and a screw portion 204b with a screw thread on the outer periphery. The hanging bracket 204 is inserted into a hanging bracket mounting hole (hereinafter referred to as a "bracket mounting hole") (not shown) that is provided in the steel plate that forms the top surface of the housing 201 and penetrates the steel plate in the plate thickness direction, and is combined with a nut provided on the opposite side of the hanging bracket 204 (inside the housing) with the steel plate between them (screwed into the nut), and is fixed to the housing 201 by sandwiching the steel plate that forms the top surface of the housing 201 between the hanging bracket 204 and the nut. The nut may be fixed, for example, by welding or the like, to the side opposite the hanging hardware 204 (the inside of the housing 201) with the steel plate forming the top surface of the housing 201 in between, regardless of whether the hanging hardware 204 is attached or not.

Mounting holes (hereinafter referred to as "bolt mounting holes") for fixing bolts (reference numeral 601 in FIG. 6) (not shown) are provided on the underside (bottom surface) of the housing 201 of the control panel 106. A plurality of bolt mounting holes are provided on the underside (bottom surface) of the control panel 106, and are used when fixing the control panel 106 to a stand for fixing the installation position of the control panel 106, or to the floor surface on which the control panel 106 is installed. The fixing bolts are screwed into the bolt mounting holes to fix the control panel 106 to the stand or floor surface.

More specifically, the bolt mounting holes are provided in a member (steel plate) that constitutes the outer periphery of an opening for pulling the cable 112 into the housing 201, which is provided on the underside (bottom surface) of the housing 201. The cable 112 is routed from various electrical devices provided in the car 101 of the elevator 100 and the operation panel 111 installed at the landing 110, and is pulled into the housing 201 through the opening for pulling the cable 112.

The control panel 106 is suspended from the head 204a of the hanging bracket 204 by fixing the wire to the frame of the building in which the elevator 100 is installed, while the control panel 106 is fixed in position with its lower part fixed to the frame. This ensures that the control panel 106 is prevented from falling over even if an external force that would cause the control panel 106 to fall over is applied to the control panel 106 due to an earthquake or the like.

The housing 201 contains a number of components that make up the control panel 106. Specifically, the housing 201 contains a circuit board, a contactless relay (semiconductor relay), a contact relay such as an electromagnetic switch, an inverter, a power supply unit, and the like. The components contained within the housing 201 are connected by wiring as appropriate. In addition, the components contained within the housing 201 are connected to cables 112 that are drawn into the housing 201 via the drawing opening as appropriate.

(Configuration of control panel transport support tool)
Next, the configuration of the control panel transport support tool according to the embodiment of the present invention will be described. Figures 3 and 4 are explanatory diagrams showing the configuration of the control panel transport support tool according to the embodiment of the present invention.

In this embodiment, as an example of a control panel transport aid according to the present invention, a first control panel transport aid (hereinafter referred to as the "upper handle") attached to the top surface of the control panel and a second control panel transport aid (hereinafter referred to as the "lower handle") attached to the bottom surface of the control panel will be described.

Figure 3 shows the upper handle. As shown in Figure 3, the upper handle 300 of the embodiment of the present invention includes a fixed member 310 and a handle 320. The fixed member 310 includes a pair of legs 311 and a connecting portion 312 that connects the pair of legs 311.

The pair of legs 311 each have a shape in which one end of a plate-like member is bent to form an L-shape, and a through hole 311a for a hanging hardware is provided at the tip of the bent end. The through hole 311a for a hanging hardware penetrates the leg 311 in the thickness direction of the leg 311. The through hole 311a for a hanging hardware is disposed opposite a hardware mounting hole used to secure the control panel 106 of the elevator 100, and the hanging hardware 204 penetrates the leg 311 with an opening diameter that allows it to pass through both the hardware mounting hole and the hanging hardware 204.

In this embodiment, two (one set) of through holes 311a for the hanging hardware are provided at the same distance as the distance between the two hardware mounting holes provided on the top surface of the control panel 106. The two (one set) of through holes 311a for the hanging hardware are provided so that they can be positioned opposite two hardware mounting holes at the same time.

Three or more hanging hardware through holes 311a may be provided depending on the position of the hardware mounting holes, the number of hardware mounting holes, etc. When three or more hanging hardware through holes 311a are provided, at least two of the multiple hanging hardware through holes 311a are arranged so that they simultaneously face different hardware mounting holes.

The connecting portion 312 can be formed, for example, using a hollow cross-section round bar made of steel. By using a hollow cross-section round bar for the connecting portion 312, it is possible to ensure the strength of the connecting portion 312 while avoiding a significant increase in the weight that the worker must lift when attaching the upper handle 300 to the control panel 106 of the elevator 100. In addition, by using a hollow cross-section round bar for the connecting portion 312, it is possible to reduce the weight of the upper handle 300 and ensure good handling of the upper handle 300.

In the fixed member 310, the leg 311 and the connecting portion 312 can be fixed, for example, by welding. The leg 311 and the connecting portion 312 may also be fixed, for example, by shrink fitting or using a tapered nut. Alternatively, the leg 311 and the connecting portion 312 may be fixed, for example, by providing flanges on both ends of the connecting portion 312 in the longitudinal direction and screwing the flanges to the leg 311.

The handle 320 is attached to the connecting portion 312 of the fixed member 310. The handle 320 can be attached to the center portion in the longitudinal direction of the connecting portion 312. The handle 320 can be formed, for example, using a hollow cross-section round bar made of steel. By using a hollow cross-section round bar for the handle 320, the strength of the handle 320 can be ensured while reducing the burden on the hands of the worker who carries the heavy control panel. In addition, by using a hollow cross-section round bar for the handle, the weight of the upper handle 300 can be reduced and good handling of the upper handle 300 can be ensured.

Figure 4 shows the lower handle. As shown in Figure 4, the lower handle 400 of the embodiment of the present invention includes a fixed member 410 and a handle 420. The fixed member 410 can be realized by a pair of sheet metal members 411 that have a horizontally folded L-shape, which are formed by bending each of a pair of metal sheets that are substantially L-shaped at the bends in the L-shape.

The pair of sheet metal members 411 that form a horizontally bent L-shape each have a bolt through hole 411a that is provided on one of two surfaces that are oriented in different directions by bending a pair of metal sheets that form a substantially L-shape. Each of the pair of sheet metal members 411 has a plurality of bolt through holes 411a.

The bolt through holes 411a penetrate the sheet metal parts that form the surfaces on which the bolt through holes 411a are formed in the pair of sheet metal members 411 that form a horizontally bent L-shape along the sheet metal thickness direction of the sheet metal parts. The bolt through holes 411a each have an opening diameter that allows the shaft of a fixing bolt to pass through, and penetrate the sheet metal parts that form the surfaces on which the bolt through holes 411a are formed in the pair of sheet metal members 411 that form a horizontally bent L-shape.

The pair of sheet metal members 411 that realize the fixed member 410 are each connected to the handle 420. In the lower handle 400, the pair of sheet metal members 411 can be connected to the hand 220 by, for example, fixing the surfaces of the pair of transversely bent L-shaped sheet metal members 411 that do not have the bolt through holes 411a to both ends of the handle 420 in the longitudinal direction by welding.

The pair of sheet metal members 411 may be fixed to both ends of the handle 420 in the longitudinal direction, for example, by shrink fitting or by using a tapered nut. Alternatively, the pair of sheet metal members 411 may be fixed by providing flanges at both ends of the handle 420 in the longitudinal direction, and fastening the flanges to the pair of sheet metal members 411 with screws (bolts and nuts).

The lower handle 400 has a plurality of bolt through holes 411a. At least two of the plurality of bolt through holes 411a are arranged so as to simultaneously face different bolt mounting holes in the control panel 106. In the lower handle 400, a "set" is made up of two or more bolt mounting holes that can simultaneously face different bolt mounting holes.

In the lower handle 400, there may be multiple sets of two bolt through holes 411a that can be simultaneously opposed to different bolt mounting holes. Specifically, for example, in the lower handle 400 shown in FIG. 4, there are two sets of two bolt through holes 411a that can be simultaneously opposed to different bolt mounting holes.

(Example of a transportation procedure for the control panel 106)
Next, an example of a procedure for transporting the control panel 106 using the upper handle 300 and the lower handle 400 will be described. Fig. 5 is a flow chart showing an example of a procedure for transporting the control panel 106 using the upper handle 300 and the lower handle 400. Fig. 6 is an explanatory diagram showing an example of a transport operation of the control panel 106 using the upper handle 300 and the lower handle 400.

When transporting the control panel 106, first, the hanging bracket 204 is removed from the control panel 106 (step S501). When the worker 600 removes the hanging bracket 204 from the control panel 106, the bracket mounting hole on the top surface of the control panel 106 through which the hanging bracket 204 was screwed (passed through) is opened.

Next, the upper handle 300 is attached to the top surface of the control panel 106 (step S502). In step S502, the worker 600 aligns the hanging hardware through holes 311a of the upper handle 300 with the hardware mounting holes that have been opened by removing the hanging hardware 204 from the control panel 106. Then, with the hanging hardware through hole 311a aligned with the hardware mounting hole, the hanging hardware 204 is inserted so that it passes through both the hanging hardware through hole 311a and the hardware mounting hole, and the inserted hanging hardware 204 is screwed into the control panel 106. This allows the upper handle 300 to be fixed to the top surface of the control panel 106.

The upper handle 300 can be fixed to the control panel 106 using the hanging bracket 204, so there is no need to use separate bolts or the like to fix the upper handle 300 to the control panel 106. This eliminates the need to separately manage the hanging bracket 204 and separate bolts, improving workability and preventing the hanging bracket 204 and other items from being lost.

In the upper handle 300, at least two through holes 311a for the hanging hardware are arranged so that they face different hardware mounting holes at the same time, so that the upper handle 300 can be stably fixed to the control panel 106. By fixing the upper handle 300 to the control panel 106 at two points, the position of the upper handle 300 relative to the control panel 106 can be stabilized and the burden on the worker 600 involved in attaching the lower upper handle 300 can be minimized.

Next, the lower handle 400 is attached to the bottom surface of the control panel 106 (step S503). In step S503, the bolt through holes 411a of the lower handle 400 are made to face the bolt mounting holes in the control panel 106. Then, with the bolt through holes 411a facing the bolt mounting holes, the fixing bolts 601 are inserted so that they pass through both the bolt through holes 411a and the bolt mounting holes, and the inserted fixing bolts 601 are screwed into the control panel 106. This allows the lower handle 400 to be fixed to the bottom surface of the control panel 106.

In the lower handle 400, at least two bolt through holes 411a can be arranged to face two bolt mounting holes at the same time, so the lower handle 400 can be stably fixed to the control panel 106. By fixing the lower handle 400 to the control panel 106 at two points, the position of the lower handle 400 relative to the control panel 106 can be stabilized and the burden on the worker 600 involved in attaching the lower handle 400 can be minimized.

By fixing the upper handle 300 to the control panel 106 before the lower handle 400, when attaching the lower handle 400, one or more workers 600 can grasp the handle of the upper handle 300 that was attached earlier and tilt the control panel 106, thereby lifting the bottom surface of the control panel 106 off the ground, and the tilted position of the control panel 106 can be stably maintained. This allows another worker 600 to easily and safely fix the lower handle 400 to the control panel 106. The lower handle 400 may be fixed to the control panel 106 before the upper handle 300.

By fixing the lower handle 400 to the bottom surface of the control panel 106 using the fixing bolts 601, there is no need to prepare a separate bolt to fix the lower handle 400. This allows the fixing bolts 601 to be transported at the same time as the control panel 106, and installation work can be performed immediately after transporting the control panel 106, making the work more efficient.

In addition, by fixing the control panel 106 to the stand or floor using the fixing bolts 601 used to fix the lower handle 400, it is no longer necessary to manage the fixing bolts 601 and other bolts separately, improving workability and preventing the fixing bolts, etc. from being lost.

Fixing bolts 601 that are not used to fix the lower handle 400 may be screwed into the bolt mounting holes that are not used to fix the lower handle 400. This allows the fixing bolts 601 to be transported along with the control panel 106, improving workability and preventing problems such as losing the fixing bolts 601 or not having enough fixing bolts 601 at the installation location of the control panel 106.

In the lower handle 400 shown in FIG. 4, two sets of two bolt through holes 411a are provided, so the position of the lower handle 400 relative to the control panel 106 can be easily changed between fixing the lower handle 400 to the control panel 106 by having the fixing bolt 601 pass through both of the two bolt through holes 411a of one set and the two bolt mounting holes, and fixing the lower handle 400 to the control panel 106 by having the fixing bolt 601 pass through both of the two bolt through holes 411a of the other set and the two bolt mounting holes.

Then, the control panel 106 is transported (step S504). In step S504, one worker holds the handle 320 of the upper handle 300, and another worker holds the handle 420 of the lower handle 400, and the control panel 106 is lifted and transported to the installation location of the control panel 106. The control panel 106 can be transported safely and reliably by holding the handle 320 of the upper handle 300, which is securely fixed to the control panel 106 using the hanging bracket 204, and the handle 400 of the lower handle 400, which is securely fixed to the control panel 106 using the fixing bolt 601.

The control panel 106 is often installed in a relatively narrow and space-constrained location, such as a machine room on the top floor of a building. In such locations, it may be difficult to use a transport cart or the like to transport the control panel 106. In addition, while the control panel 106 is a precision machine that requires careful handling, it is relatively heavy and the surface of the casing 201 has few irregularities, making it difficult to hold. Therefore, the conventional method of carrying the control panel 106 directly imposes a heavy burden on the worker.

In contrast, by using the upper handle 300 and the lower handle 400 as described above, the control panel 106 can be transported stably. In addition, because the control panel 106 can be transported stably, the safety of the worker 600 can be ensured. Furthermore, by having the worker 600 transport the control panel 106 by lifting it in his or her hands without using a cart or the like, the control panel 106 can be transported efficiently, even in a small space, with a small turning radius, and damage to the control panel 160 or surrounding objects can be avoided.

Next, after transporting the control panel 106 to the vicinity of the installation location, the upper handle 300 and the lower handle 400 are removed from the control panel 106 (step S505). When removing the upper handle 300 and the lower handle 400 in step S505, for example, for the same reason as above, the lower handle 400 is removed first, and then the upper handle 300 is removed. The upper handle 300 and the lower handle 400 removed from the control panel 106 in step S505 can be reused when transporting another control panel 106.

As a result, during the operation of removing the lower handle 400, the worker 600 holding the upper handle 300 places one side of the bottom surface of the housing 201 of the control panel 106 on a stand or floor, and lifts up the side opposite that side, thereby maintaining the tilted state of the control panel 106 in a stable state. This makes it possible to ensure a working space below the bottom surface of the housing 201 of the control panel 106 for removing the lower handle 400, thereby improving the working efficiency and ensuring safety of the worker 600 removing the lower handle 400.

In addition, by first removing the lower handle 400, the control panel 106 after removing the lower handle 400 can be placed on a stand or floor surface slowly and gently while holding the upper handle 300. This allows the control panel 106, which is a precision machine, to be installed without shock, and prevents damage to the control panel 106 caused by transportation and installation.

The upper handle 300 can be removed by removing the loosened hanging bracket 204 from the control panel 106. The lower handle 400 can be removed by removing the loosened fixing bolt 601 from the control panel 106.

Then, the control panel 106 from which the upper handle 300 and the lower handle 400 have been removed is fixed (step S506). In step S506, the fixing bolts 601 from which the lower handle 400 has been removed from the control panel 106 are screwed together with the control panel 106 to the stand or the floor surface, thereby fixing the control panel 106.

In addition, in step S506, the hanging bracket 204 that was removed from the control panel 106 when the upper handle 300 was removed is fixed again to the top surface of the control panel 106. After that, a wire (not shown) is hung on the top of the hanging bracket 204 that is fixed to the control panel 106 that is fixed to the stand or floor, and the wire is fixed to the building frame or the like to secure the control panel 106 in place (to prevent it from falling over).

In step S506, in conjunction with fixing the control panel 106, some of the components that make up the elevator (for example, the car, the hoist, etc.) may be replaced. By replacing only some of the components, as described above, it is possible to reduce the costs of renovation and the time required for renovation work that would render the elevator unusable.

If the type of programming language or description method used to write the control program for controlling each component is different between the control panel before replacement (hereinafter referred to as the "old control panel" as appropriate) and the new control panel 106 after replacement, the existing (remaining) components that have not been replaced and that were controlled by the old control panel (hereinafter referred to as the "old components" as appropriate) will not be able to understand the control signals from the control panel 106.

For this reason, in step S506, a signal conversion device (not shown) may be further installed. The signal conversion device converts the signal output by the old configuration unit into another signal that has the same meaning as the signal and that can be understood by the control panel 106. The signal conversion device also converts the signal output by the control panel 106 into another signal that can be understood by the old configuration unit.

Specifically, in step S506, the control panel 106 is fixed, and a signal conversion device is connected between the control panel 106 and the old components. At the same time, at least one of the old components is replaced with a new component that can understand the signals output by the control panel 106 and outputs signals that the control panel 106 can understand. This makes it possible to reduce the costs involved in the renovation, as well as the time required for the renovation work that would cause the elevator to become unusable.

The signal conversion device is connected to the new components replaced by the renewal, the existing (remaining) components that have not been replaced (hereinafter referred to as "old components"), and the new control panel 106 in a state in which communication is possible, for example, by a serial transmission method. The signal conversion device may also be connected to the new components, the old components, and the control panel 106 in a state in which communication is possible by a parallel transmission method.

Furthermore, the signal conversion device may convert into multiple different types of signals depending on the connection destination, for example, a serial transmission method between the control panel 106 and the new component, and a parallel transmission method between the old component, etc.

After that, the operation of the newly installed control panel 106 is checked (step S507), and the series of processes is terminated. In step S507, for example, the replaced control panel 106 outputs a signal to each component of the elevator 100, instructing them to execute a specified operation. The replaced control panel 106 also receives signals output from the corresponding components in response to the signal. Then, based on the output and reception results of these signals, it is checked whether the control panel 106 and each component connected to the control panel 106 are operating normally.

In addition, in step S507, the operation of the control panel 106 may be confirmed by having the worker 600 visually check the operation of each component in response to a signal output from the replaced control panel 106.

As described above, the upper handle 300 of the embodiment of the present invention is characterized by having a fixed member 310 with a through hole 311a for the hanging hardware through which the hanging hardware 204 can pass together with the hardware mounting hole when placed opposite the hardware mounting hole, and a handle 320 connected to the fixed member 310.

According to the upper handle 300 of the embodiment of the present invention, the hanging hardware 204 is fixed to the control panel 106 so as to pass through both the hardware mounting hole and the through hole 311a for the hanging hardware facing the hardware mounting hole.

And, according to the upper handle 300 of the embodiment of the present invention, by fixing the upper handle 300 to the control panel 106 at multiple points, the worker 600 can grasp the handle 320 of the upper handle 300 and transport the control panel 106 in a stable state. This reduces the burden on the worker 600 and allows the control panel 106 to be transported easily and quickly.

This allows the control panel 106 to be transported easily and quickly without being damaged when renovating the elevator 100.

As a result, it is possible to shorten the time required to renovate the elevator 100, shorten the time that users are unable to use the elevator, and improve user convenience.
