[Prior art documents] [Patent documents]
[0004] [Patent Document 1] JP 2017-124677 A [Patent Document 2] JP 2018-150006 A Summary of the Invention
[0005] The present invention has been made in consideration of the above-mentioned points, and aims to provide a platform fence device that does not require dedicated maintenance personnel and allows parts to be easily replaced in a short amount of time.
[0006] In order to achieve the above-mentioned objective, the platform fence device of the present invention comprises a door body, a platform fence main body which holds the door body so that it can be moved forward and backward, and a comprehensive parts unit which is stored in the platform fence main body and which consolidates and mounts a number of parts used for control and drive, and the comprehensive parts unit is incorporated so that it can be replaced all at once as a maintenance part.
[0007] According to the above-mentioned platform gate device, the time until the failure is restored can be shortened by replacing the comprehensive parts unit all at once, regardless of the type of failure. Since the failure restoration work only involves replacing the comprehensive parts unit, even station staff who are not specialized maintenance personnel can easily perform the failure restoration work. In addition, there is no need to dispatch maintenance personnel or spend time transporting maintenance parts from the maintenance base, which shortens the time until the failure is restored.

[0009] [First embodiment] Hereinafter, the platform fence device of the first embodiment will be described with reference to the drawings.
[0010] Fig. 1 is a conceptual diagram illustrating the platform fence device 100. Fig. 1 is a diagram of the platform fence device 100 as viewed from the platform PF side, and shows the state in which the exterior panel on the platform PF side of the platform fence device 100 has been removed. Figs. 2(A) and 2(B) are a front view and a rear view illustrating the integrated parts unit 40 of the platform fence device 100. Fig. 2(C) is a side cross-sectional view illustrating the platform fence device 100.
[0011] The platform fence device 100 separates the platform PF and the track RL of a station. The platform fence device 100 is also called a movable platform fence. The platform fence device 100 is composed of a predetermined number of platform door elements 10 arranged in a row to cover a predetermined area of the platform PF. Each platform door element 10 has a door body 20 and a platform fence main body 30. In the example of FIG. 1, in each platform door element 10, a pair of door bodies 20 protrude from the end opening of the platform fence main body 30 and close the boarding and alighting passage, thereby forming a series of platform fences that extend along the edge of the platform PF as a whole.
[0012] The door body 20 is a door member that is housed within the platform fence main body 30 and is provided so as to be freely inserted and removed. The door body 20 has a main door body 21 that moves laterally forward and backward from a first end 32 that is one end of the platform fence main body 30, and a secondary door body 22 that moves laterally forward and backward from a second end 33 that is the other end of the platform fence main body 30. Usually, the main door body 21 and the secondary door body 22 are controlled to open and close in conjunction with each other.
[0013] The platform fence main body 30 is fixed to the floor of the platform PF and has a door pocket structure that holds the door body 20 so that it can move forward and backward. The platform fence main body 30 has a comprehensive parts unit 40, a guide mechanism 50, and a transmission mechanism 60 inside a housing 31. The inside of the platform fence main body 30 is hollow except for the areas where the comprehensive parts unit 40, the guide mechanism 50, and the transmission mechanism 60 are arranged.
[0014] The comprehensive parts unit 40 is housed and built into the platform fence main body 30, and is equipped with a plurality of parts including all electrical and mechanical mechanisms that are subject to maintenance. The comprehensive parts unit 40 is built into the housing 31 of the platform fence main body 30 so that it can be replaced as a maintenance part. The platform fence main body 30 includes only one comprehensive parts unit 40. In the case of replacing a maintenance part, since a single comprehensive parts unit 40 is replaced, the failure recovery work can be easily performed in a short time. The comprehensive parts unit 40 is attached and detached from the side part VX (specifically, the first end part 32) through which the door body 20 of the platform fence main body 30 advances and retreats. The comprehensive parts unit 40 is pulled out from the side part VX of the platform fence main body 30, which makes it easy to attach and detach the comprehensive parts unit 40.
[0015] As shown in Figs. 2(A) to 2(C), the integrated parts unit 40 includes a control device 41, a power supply device 42, an individual operation panel 43, a motor 44, a relay device 45, a sensor 46, an emergency open button 47, and an indicator light 48. The control device 41, the power supply device 42, the individual operation panel 43, the motor 44, the relay device 45, the sensor 46, the emergency open button 47, and the indicator light 48 are parts used for control and drive. In the integrated parts unit 40, the control device 41, the power supply device 42, the individual operation panel 43, the motor 44, and the relay device 45 are disposed in the housing 31. The sensor 46, the emergency open button 47, and the indicator light 48 are disposed so as to be partially or entirely exposed outside the housing 31.
[0016] The component integration unit 40 has a base BB on which the above-mentioned multiple components are arranged. The above-mentioned components can be fixed in appropriate positions on the base BB, making it easy to handle the component integration unit 40. The component integration unit 40 has, as the base BB, a first support BB1 arranged on the platform PF side and a second support BB2 arranged on the track RL side. This allows the components to be arranged in necessary locations on the platform PF side and the track RL side even with a single component integration unit 40. The first support BB1 and the second support BB2 are connected by a connecting portion BB3 provided on the upper side. In other words, the component integration unit 40 has a U-shape or a shape bent so as to surround the door body 20 in the side cross-sectional view shown in FIG. 2(C).
[0017] A control device 41, a power supply device 42, an individual operation panel 43, a motor 44, and a relay device 45 are arranged on the base surface of the first support BB1. An indicator light 48 is arranged on the upper part of the first support BB1. A sensor 46 and an emergency open button 47 are arranged on the base surface of the second support BB2.
[0018] The base BB of the comprehensive parts unit 40 occupies half or less of the platform fence main body 30 in the lateral direction when viewed from a direction perpendicular to the forward and backward movement of the door body 20. In this way, the comprehensive parts unit 40 aggregates multiple parts on the base BB, so that it is possible to significantly reduce the space inside the platform fence main body 30. The size of the comprehensive parts unit 40 can be changed as appropriate as long as it is a size that allows replacement.
[0019] The base BB has a pull-out handle HD on one side Ba and a roller RO on the bottom Bc. The handle HD is a member for pulling out the comprehensive parts unit 40 from the platform fence main body 30, and has a structure (e.g., a lift-lid handle, a drop-in handle, a push-type handle, a rotating handle, etc.) that can be inserted into and removed from a recess (not shown) formed in the base BB, or other structures (e.g., a recessed handle, etc.) (see FIG. 2(B)). The roller RO is, for example, a wheel, and is a member for smoothly moving the comprehensive parts unit 40 in the lateral direction. The comprehensive parts unit 40 is taken out of the housing 31 using the handle HD with the door body 20 housed in the platform fence main body 30, specifically, the housing 31. Although not shown, the comprehensive parts unit 40 has a fixing device for fixing the comprehensive parts unit 40 when housed in the housing 31.
[0020] The control device 41 has a control board 41a, a drive circuit 41b, and a speaker 41c. The control board 41a is a computer, and controls the operating state of the door body 20. The drive circuit 41b provides driving force to the motor 44 while checking the position of the door body 20. The speaker 41c generates sounds and warning sounds to notify the opening and closing of the door body 20. The control device 41 receives opening and closing signals and the like from a comprehensive control device 70 separately provided on the platform PF, and controls the operation of the platform fence device 100. The comprehensive control device 70 and the control device 41 provided on each platform fence device 100 are connected to each other and can communicate with each other. This allows the platform fence devices 100 to operate in conjunction with each other.
[0021] The power supply device 42 is a device that receives an AC power source such as a commercial power source as input, and includes a power supply circuit 42a and a breaker 42b. The power supply circuit 42a supplies power to each component such as the control device 41. The breaker 42b is a circuit breaker that protects the components from overcurrent and the like.
[0022] The individual operation panel 43 accepts individual opening and closing operations performed on the door body 20 by a train crew member, station staff, etc. This allows the door body 20 to be manually operated independently of the interlocking operation of the platform fence device 100. The control device 41 transmits the open / closed state and abnormalities of the door body 20 based on the operation instructions of the individual operation panel 43 to the general control device 70. Although not shown in the figure, the individual operation panel 43 can be exposed by removing part of the exterior panel on the platform PF side. This allows station staff, etc. to manually operate the individual operation panel 43.
[0023] The motor 44 is a rotary drive device, and generates a driving force to move the door body 20. The motor 44 has a first motor 44a that drives the main door body 21 and a second motor 44b that drives the secondary door body 22.
[0024] The relay device 45 can communicate with a management device 90 installed in a station control room via a communication line NT shown in FIG. 1, and receives a control signal from the management device 90. The relay device 45 transmits an alarm to the management device 90 when an abnormality or failure occurs in the platform fence device 100. The management device 90 can also communicate with the general control device 70 via the communication line NT, and transmits a signal to inhibit the departure of a train when an abnormality or the like occurs. The communication line NT may be a local area network (LAN), a wide area network (WAN), the Internet, or a combination of these. The communication line NT may also include a public switched telephone network (PSTN), an integrated services digital network (ISDN), or the like.
[0025] The sensor 46 is an optical obstacle sensor that detects obstacles such as people and objects present in the detection space between the rear face of the platform fence device 100 and the train. The sensor 46 is, for example, a three-dimensional scanner, an infrared sensor, etc. Data obtained by the sensor 46 is output to the control device 41, and the data is processed appropriately to determine whether or not there is an obstacle.
[0026] The emergency open button 47 is a button for opening the door body 20 from the track RL side or the train side in the event of an emergency. The on / off state of the emergency open button 47 is read by the control device 41.
[0027] The indicator light 48 operates under the control of the control device 41 and indicates the open / closed state of the door body 20. For example, the indicator light 48 turns on when the door body 20 is open and turns off when the door body 20 is closed. The indicator light 48 also turns on when an abnormality occurs in the platform fence device 100.
[0028] After the replacement, the integrated parts unit 40 replaces and repairs the broken parts. The integrated parts unit 40 can be returned to a maintenance base, each part inspected, and the broken parts replaced and repaired, and then reused as a replacement integrated parts unit 40, thereby reducing the environmental impact.
[0029] FIG. 4B shows the state where the side panel SP is removed from the housing 31. The component integration unit 40 is usually covered by the side panel SP at the side VX, and is not exposed except for some components (specifically, the sensor 46, the emergency open button 47, and the indicator light 48). The side panel SP is attached to the side VX close to the area where the component integration unit 40 is arranged, so as to cover the periphery of the door body 20 using bolts (not shown). The side panel SP has a notch 35a and openings 35b and 35c on the back surface 35d. The notch 35a has a shape corresponding to the indicator light 48 of the component integration unit 40. The openings 35b and 35c have shapes corresponding to the sensor 46 and the emergency open button 47. By removing the side panel SP, the component integration unit 40 can be replaced.
[0030] 1 is composed of mechanical parts including rollers, adjustment jigs, etc. (not shown) in addition to the guide rail 51. The guide rail 51 is disposed so as to sandwich the top and bottom of the door body 20. The guide mechanism 50 enables the door body 20 to move laterally smoothly, that is, to open and close the door body 20.
[0031] The transmission mechanism 60 shown in FIG. 1 is composed of mechanical parts including a belt 61, a pulley 62, and a connector (not shown). Although FIG. 1 shows the platform fence device 100 without the exterior panel on the platform PF side, in reality, the transmission mechanism 60 is attached to the exterior panel. The transmission mechanism 60 transmits the driving force of the motor 44 to the door body 20. Specifically, the transmission mechanism 60 and the motor 44 are provided corresponding to the main door body 21 and the secondary door body 22, respectively. As a result, the driving force of the first motor 44a is transmitted to the main door body 21, and the driving force of the second motor 44b is transmitted to the secondary door body 22.
[0032] The overall control device 70 is provided on the platform PF, specifically, near the platform fence devices 100 or in one of the platform fence devices 100. The overall control device 70 is connected to a plurality of platform fence devices 100 and performs interlocking control of the platform fence devices 100. The overall control device 70 is capable of communicating with the management device 90 via a communication line NT, and transmits and receives data.
[0033] The management device 90 receives operation data of the platform fence device 100 from the relay device 45 or the overall control device 70 via the communication line NT, and performs overall management of the platform fence device 100.
[0034] 3 and 4, the maintenance and parts replacement of the platform fence device 100 will be described. The platform fence device 100 monitors the operation of the door body 20 by a monitoring device (not shown) and notifies the control device 41 when an abnormality is detected.
[0035] First, the control device 41 detects an abnormality in the platform fence device 100, specifically, a malfunction of the door body 20, etc. (Step S11). The control device 41 notifies the management device 90 of an alarm via the relay device 45 and requests maintenance. In the platform fence device 100 where an abnormality has occurred, the indicator light 48 is turned on.
[0036] In response to the request in step S11, a new replacement integrated parts unit 40 is prepared by station staff (step S12).
[0037] If the door body 20 is not stored in the housing 31 (No in step S13), the control device 41 stores the door body 20 in the housing 31 by the station staff operating the individual operation panel 43 to close the door (step S14, see Figure 4 (A)).
[0038] After step S14, the side panel SP is removed by a station staff member (step S15, see FIG. 4(B)).
[0039] Next, the old parts comprehensive unit 40 is pulled out from the housing 31 by the station attendant (step S16). Specifically, as shown in Fig. 4(C), the parts comprehensive unit 40 is released from the fixing device (not shown) and the station attendant grasps the handle HD and moves it to the side, that is, in the direction in which the door body 20 closes, thereby pulling the parts comprehensive unit 40 out from the housing 31. The rollers RO allow the parts comprehensive unit 40 to move smoothly.
[0040] Next, the new parts integration unit 40 is inserted into the housing 31 by a station attendant (step S17). The parts integration unit 40 is accommodated in a predetermined position within the housing 31 and fixed by a fixing device (not shown).
[0041] Next, the side panel SP is attached to the housing 31 by a station attendant (step S18).
[0042] Finally, the old integrated parts unit 40 is collected and repaired (step S19). Specifically, the old integrated parts unit 40 is transported to a maintenance base or the like, and each part mounted on the integrated parts unit 40 is inspected, repaired, replaced, or the like.
[0043] According to the above-mentioned platform fence device 100, the time until the failure recovery can be shortened by replacing the comprehensive parts unit 40 all at once, regardless of the type of failure. Since the failure recovery work only involves replacing the comprehensive parts unit 40, even station staff who are not specialized maintenance personnel can easily perform the failure recovery work. In other words, by replacing the comprehensive parts unit 40, it is not necessary for a maintenance personnel to identify the failed parts, and there is no need to dispatch a maintenance personnel from the maintenance base to the station. In addition, the maintenance parts are limited to only the comprehensive parts unit 40, and the comprehensive parts unit 40 can be easily managed even if it is stored at the station. As a result, there is no need to spend time dispatching a maintenance personnel or transporting the maintenance parts from the maintenance base, and the time until the failure recovery can be shortened.
[0044] Second Embodiment Hereinafter, a second embodiment, which is a modification of the first embodiment, will be described with reference to FIG.
[0045] 5, in the platform fence device 100, the component integration unit 40 is divided into two bases BB. Specifically, the component integration unit 40 is separated into a first support BB1 and a second support BB2.
[0046] The integrated parts unit 40 of this embodiment is a plate-shaped unit, which makes it easy to handle and store.
[0047] The integrated parts unit 40 of the present embodiment may be divided into three or more boards to the extent that ease of replacement can be maintained. In this case, it is preferable that each divided board is fixed to the adjacent board by a jig, fixture, frame, or the like.
[0048] 〔others〕 The present invention is not limited to the above-described embodiment, and can be embodied in various forms without departing from the spirit and scope of the present invention.
[0049] As described above, the integrated parts unit 40 has common specifications and can be standardized for different platform fence devices 100, any line, any platform PF, and any station.
[0050] In the above embodiment, the types, shapes, sizes, arrangements, etc. of the components mounted on the integrated components unit 40 can be changed as appropriate.
[0051] In the above embodiment, an opening or the like is provided in the side panel SP, but a configuration in which the panel on the side surface of the housing 31 is removed without providing an opening or the like may also be adopted. In this case, the protruding parts of the comprehensive parts unit 40 (specifically, the sensor 46, the emergency open button 47, and the indicator light 48) may be, for example, socket-type parts, and the protruding parts are temporarily removed from the comprehensive parts unit 40, and then the comprehensive parts unit 40 is pulled out from the platform fence main body 30.
