Description

  The present invention relates to a barrier-free boarding facility, and more particularly to a barrier-free boarding facility that is installed on a quay where a ship such as a ferry is anchored and can be boarded and boarded using a wheelchair as well as a healthy person.

  As a barrier-free boarding facility that can be installed on a quay and that can move up and down the slope corresponding to the boarding board of the ship that moves up and down due to ship swaying and tidal, for example, patent literature One described in “1. Wheelchair boarding device” is known. A conventional barrier-free boarding facility is equipped with a lifting cage for a wheelchair that can be lifted by a winch on a staircase turret that boardes and disembarks via a platform at the top of the platform. A floor (slope) is provided so that it can be withdrawn and retracted, and the lifting cage is controlled by a command from the automatic stopping device based on the detection signal of the boarding / leaving position of the ship detected by the position sensor provided on the lifting cage, and the lifting cage is stopped. Is.

Japanese Patent No. 2723444

By the way, it is desirable that the barrier-free boarding / exiting facility has a configuration capable of traveling on the quay. This means that when boarding and disembarking, the barrier-free boarding and unloading equipment is brought close to the ship and the slope is passed from the platform to the ship's boarding and unloading deck. This is to evacuate the barrier-free boarding facility to the storage. In this case, as for the movement method of the barrier-free boarding / exiting facility, the hand-pushing method using the carriage does not require a power transmission system such as a drive motor and a reduction gear, and is more economical than the automatic traveling type. However, in the case of a hand-held type equipment, it is desirable to reduce the weight of the entire equipment in order to reduce the labor of the worker when the operator pushes the barrier-free boarding facility.
However, the barrier-free boarding / exiting facility is heavier than the case of using only the boarding / unloading apparatus by the amount that the lifting device is connected to the boarding / unloading apparatus. Therefore, the labor of the worker who moves the barrier-free boarding / exiting facility has been increased.
In order to solve this problem, it is conceivable to use a barrier-free boarding / unloading facility in which the boarding / unboarding apparatus and the lifting / lowering apparatus are separated, and the boarding / unboarding apparatus and the lifting / lowering apparatus are arranged close to each other when boarding / leaving. However, if the lifting device is used in a state separated from the boarding / alighting device in this manner, an unexpected situation may occur in which the lifting cage swings or, in the worst case, the lifting device falls over when getting on or off a wheelchair.

  Therefore, as a result of earnest research, the inventor has come up with the idea that the boarding / elevating device and the lifting device are separately movable, and that they are connected and integrated only during boarding / exiting. With this configuration, we learned that it is possible to achieve both the ease of movement of the barrier-free boarding facility when moving equipment (reduction of moving operation force) and the stability of the lifting device when boarding and unloading wheelchairs. Completed the invention.

  An object of the present invention is to provide a barrier-free boarding / unboarding facility that can achieve both the ease of movement of the barrier-free boarding / exiting facility when moving the facility and the stability of the lifting device when boarding / dismounting a wheelchair.

The invention described in claim 1 is a boarding / disembarking device that is disposed on a quay and temporarily bridges a slope with a ship, is detachably connected to the boarding / disembarking device by positioning connecting means, and A barrier-free boarding / unboarding facility equipped with a lifting / lowering device used when a user gets on / off, wherein the boarding / unboarding device is arranged on the quay and has a platform on the upper part. A staircase having an upper part connected to the platform, a first carriage provided at a lower part of the first frame, a base part supported in a cantilevered state on the platform, and a front part being a boarding / alighting deck of the ship The lifting device is disposed on the quay and has an entrance at the time of lowering of the wheelchair formed on one side, and the opening side is at the entrance of exiting at the time of lowering of the wheelchair. Toward A second U-shaped gantry in a plan view; and a second U-shaped trolley provided in a lower portion of the second gantry and having an opening side facing the entrance when the wheelchair is lowered. The lift cage is disposed in the inner space of the second frame so as to be able to move up and down, and is mounted on the wheelchair, and is provided on the second frame, and passes through the inner spaces of the second frame and the second carriage. A lifting and lowering means for raising and lowering the lifting cage between the quay ground and the platform, and the positioning and connecting means is configured to connect the lifting and lowering device to a lifting and lowering device connecting region formed on the boarding and unloading ship device. A barrier-free boarding / disembarking facility having a positioning fitting structure for positioning, and a connecting structure for connecting the positioned lifting device to the boarding / unloading device.

  According to the first aspect of the present invention, after the ship has berthed, the boarding / disembarking facility is brought close to the ship, the slope is passed from the platform to the boarding deck of the ship, and then the boarding / disembarking ship stored in the quay's turret storage area. The device and the lifting device are moved to the vicinity of the ship on the quay while the operator individually pushes them using the corresponding first and second carts. Next, the lifting / lowering device is positioned in the lifting / lowering device connection region of the boarding / unloading device by the positioning fitting structure of the positioning connecting means, and then the positioned lifting device is connected to the boarding / unboarding device via the connection structure. Then, the wheelchair user uses a lifting device to board and disembark. Specifically, the raising / lowering cage is lowered by the cage raising / lowering means through the internal spaces of the second frame and the second carriage, and the bottom plate is grounded to the quay. Next, the wheelchair gets on and off the lifting cage through the lowering entrance of the second frame. At this time, since the second carriage has a U-shape when viewed in plan, the bottom plate of the lifting cage is directly grounded to the quay, so there is almost no step between the quay and the top surface of the bottom plate of the lifting cage. Therefore, when a wheelchair gets on and off the lifting cage at the quay, even a single wheelchair user can get on and off the lifting cage without any problem.

As described above, since the boarding / elevating device and the lifting / lowering device are provided so as to be movable separately from each other and both are connected and integrated only when boarding / alighting, the operator pushes when moving the barrier-free boarding / alighting equipment. Reduces the weight of the single object As a result, it is easy to move the barrier-free boarding / exiting facility by human power, and unexpected movement such as shaking of the elevating cage and falling of the elevating apparatus, which are a concern when the elevating apparatus is lifted / lowered while being separated from the boarding / exiting device. The situation is resolved and the stability of the lifting device when getting on and off a wheelchair can be improved.
In addition, when getting on and off the ship after berthing, the healthy person gets in the ship from the quay through the stairs, the platform, and the slope in order, and gets off from the ship to the quay by reversing this order of passage. Of course, a healthy person may get on and off using the lifting device.

Barrier-free boarding / exiting facilities here include both boarding / unboarding devices, which are stepped turrets used by healthy people, and lifting devices, such as elevators and lifting lifters, used by wheelchair users. In this invention, it is set as the structure which can be attached or detached to boarding / alighting apparatus.
As a ship using the barrier-free boarding / exiting facility, for example, various passenger ships, various cargo ships, etc. can be adopted in addition to ferries.
The first mount and the second mount are mobile ones mounted on the corresponding first and second carts.
The first cart and the second cart are of the push type in which a plurality of casters are arranged on the back surface of the base plate on which the corresponding mount is mounted. However, these carts may be self-propelled carts using a motor as a drive source if necessary.

The slope is a cantilevered corridor with a flat passage surface through which healthy persons and wheelchairs pass. The slope may be configured to be extendable in the length direction, or may be configured to be able to be raised and lowered about a horizontal elevation axis by an elevation means provided on the first frame. Thereby, a slope can be raised / lowered corresponding to the boarding / alighting deck of a ship moved up and down by tides.
The platform functions as a landing with a stairway where healthy people ascend and descend to the upper floor of the first frame on which the slope is installed, and a lifting device where a wheelchair user moves up and down.

The lifting device is a device that is detachably connected to the boarding and unloading device, and that lifts and lowers the lifting cage on which the wheelchair is mounted by the cage lifting means between the ground surface of the quay and the platform.
Here, “raising and lowering the lifting cage between the ground contact surface of the quay and the platform” means that the lower surface of the lifting cage is in the lowest position where it contacts the ground contact surface of the quay and the upper surface of the lifting cage is the upper surface of the platform. As the uppermost position having the same height, it means raising and lowering the lifting cage by the cage lifting means.
As the cage lifting / lowering means, for example, a worm jack type lifting / lowering device, a chain drive type lifting / lowering device or the like can be adopted.
The positioning connecting means positions the lifting device in the lifting device connection area of the boarding / unboarding device by the positioning fitting structure, and then connects the positioned lifting device to the boarding / unboarding device by the connection structure. As long as it is possible to get on and off the platform of the wheelchair, the formation position of the lifting / lowering device connection region in the boarding / alighting device is arbitrary. The lifting device and the boarding / alighting device are detachably connected, but they can also be moved and used while being connected.

The positioning and fitting structure includes a male (convex) side fitting member and a female (concave) side fitting member, one of which is provided on the boarding / disembarking device and the other of which is provided on the lifting device. Is a member that positions the lifting device in the lifting device connection region of the boarding / unloading boat device by detachably fitting. For example, a V-shaped catcher, an L-shaped catcher, a conical catcher, or the like can be employed.
The connection structure is a member that removably connects the positioned lifting device and the boarding / unloading device. For example, shrimp metal fittings (ancho fasteners), hinge bolts, wing nuts, etc. can be employed as the connecting structure.

  According to a second aspect of the present invention, the positioning fitting structure is disposed on the surface of the boarding / disconnecting device connected to the lifting / lowering device so as to be spaced apart in the horizontal direction and gradually toward the tip. A pair of positioning outer fitting members having a long separation width and a surface on the connection side of the lifting device and the boarding / alighting device are spaced apart in the horizontal direction, and gradually toward the tip. And a pair of positioning inner fitting members that are detachably fitted to the corresponding positioning outer fitting members. A shrimp gold disposed between a lower part on the connection side with the device and a lower part on the connection side with the boarding / alighting device of the lifting device, each of which is horizontally oriented in the width direction; A pair of lower shrimp metal fittings and a lifting device of the boarding / alighting device Between the portion above the installation position of the pair of lower shrimp metal fittings and the part above the installation position of the pair of lower shrimp metal fittings on the connection side of the lifting device with the boarding / exiting device. 2. The barrier-free boarding facility according to claim 1, further comprising a pair of upper shrimp metal fittings composed of shrimp gold having at least one of which is vertically oriented in the width direction and a receiver of the shrimp gold.

According to the second aspect of the present invention, when the lifting device is positioned (when the device is positioned), the pair of positioning inner fitting members and the pair are installed in the lifting device connection region of the boarding / alighting device disposed near the ship on the quay. The lifting device is positioned through the positioning outer fitting member. That is, of the pair of positioning outer fitting members, the sloped surface is gradually widened toward the tip, and the corresponding positioning inner fitting member is gradually moved toward the tip. The elevating device is positioned in the elevating device connection area of the boarding / alighting device using a tapered inclined surface with a reduced separation width as a positioning guide.
After positioning, when connecting the lifting / lowering device to the boarding / unloading device (when the device is connected), a pair of upper shrimp metal fittings and a pair of lower shrimp metal fittings are used to connect to the second frame of the first frame. The side and the connection side with the 1st mount among the 2nd mounts are connected. By using the shrimp fitting as the positioning connecting means, the lifting device can be easily and firmly connected to the boarding / unloading device. Specifically, in each upper shrimp metal fitting and each lower shrimp metal fitting, the shrimp gold connected to one of the lifting device and the boarding / unloading device is firmly fixed to the receiving metal connected to the other of the lifting device and the boarding / shipping device. Hang.

  Further, at least one of the pair of upper shrimp metal fittings is a shrimp metal fitting composed of a shrimp gold and a receiving metal whose width direction is oriented vertically so that rigidity against a force from the vertical direction is increased. As a result, when reaching the platform of the lifting cage where the weight load from above on the connecting portion between the boarding / alighting device and the lifting device reaches the platform, the weight load is mainly received by the pair of upper shrimp fittings. At this time, as described above, since at least one upper shrimp metal fitting is composed of a shrimp gold and a receiving metal with the width direction oriented vertically, for example, both the pair of upper shrimp metal fittings are horizontally arranged in the width direction. Compared to the case where the shrimp gold is directed to the shrimp and the receiver, deformation of the shrimp metal fitting due to the weight load from above can be prevented.

The outer shape of the pair of positioning outer fitting members is arbitrary as long as the distance between the pair of outer fitting members gradually increases toward the tip.
As used herein, “a shape in which the separation width gradually increases toward the tip” may be a trumpet shape, for example.
The outer shape of the pair of positioning inner fitting members is arbitrary as long as the distance between the inner fitting members for positioning gradually decreases toward the tip.
Here, for example, a bud shape, an arrowhead shape, or the like can be adopted as the “shape in which the separation width gradually decreases toward the tip”.

The shrimp gold constituting the main body part of the shrimp metal fitting is connected to the lever attached to one of the connecting side of the lifting / lowering device and the connecting side of the lifting / lowering device with a spring. The appearance of connecting pieces is a multi-jointed plate-like metal fitting similar to shrimp. Since shrimp gold is an articulated plate-like metal fitting, the rigidity against external force acting from the thickness direction is small and easily deformed. On the other hand, plate-like shrimp gold has a high rigidity against an external force acting from its width direction and is not easily deformed.
The catcher is a hook-shaped metal fitting fixed to the other of the connection side of the boarding / alighting device with the lifting / lowering device and the side of the lifting / lowering device connected to the boarding / alighting device.
Only one of the pair of upper shrimp metal fittings may be a shrimp metal fitting made of a shrimp gold having a width direction oriented vertically and a shrimp gold receiving metal. Further, both of them may be a shrimp metal fitting made of shrimp gold whose width direction is vertical and a shrimp gold catcher. However, both (the latter) are desirable in order to firmly support the load from the ascending / descending cage that acts on the upper part of the connecting portion between the boarding / alighting device and the lifting device.

According to the first aspect of the present invention, the operator pushes the boarding / elevating device and the lifting device being stored in the quayside tarp storage area using the corresponding first and second carts. While moving to the quay near the ship. After that, the lifting device is positioned in the lifting device connection area of the boarding / unloading device by the positioning fitting structure of the positioning connecting means, and then the positioned lifting device is connected to the boarding / unboarding device via the connection structure. After that, the elevator cage on which the wheelchair user has boarded is lifted and lowered by the cage lifting means, so that a barrier-free boarding / disembarking ship using the lifting device of the wheelchair user can be performed. At this time, since the second carriage has a U-shape when viewed in plan, the bottom plate of the lifting cage is directly grounded to the quay, so there is almost no step between the quay and the top surface of the bottom plate of the lifting cage. Therefore, when a wheelchair gets on and off the elevator cage at the quay, even a single wheelchair user can get on and off the elevator cage without any problem.
As described above, since the boarding / elevating device and the lifting / lowering device are provided so as to be movable separately from each other and both are connected and integrated only when boarding / alighting, the operator pushes when moving the barrier-free boarding / alighting equipment. Reduces the weight of a single object As a result, it is easy to move the barrier-free boarding / exiting facility by human power, and unexpected movement such as shaking of the elevating cage and falling of the elevating apparatus, which is a concern when the elevating apparatus is lifted and lowered from the boarding / exiting device, are expected. The situation is resolved and the stability of the lifting device when getting on and off a wheelchair can be improved.

In particular, according to the second aspect of the present invention, when the lifting device and the boarding / unboarding device are connected, the pair of positioning inner fitting members are disposed in the lifting device connection region of the boarding / unboarding device disposed near the ship on the quay. And the lifting device are positioned via the pair of positioning outer fitting members. That is, of the pair of positioning outer fitting members, the sloped surface is gradually widened toward the tip, and the corresponding positioning inner fitting member is gradually moved toward the tip. Both devices are positioned using a tapered inclined surface with a short separation width as a positioning guide surface.
When connecting the lift device after positioning and the boarding / unboarding device, a pair of upper shrimp metal fittings and a pair of lower shrimp metal fittings are used, the connection side of the boarding / elevating device with the elevator device, and the boarding / unboarding device of the boarding / unboarding device Connect to the connecting side.

  Further, at least one of the pair of upper shrimp metal fittings is a shrimp metal fitting made of shrimp gold and a receiving metal with the width direction oriented vertically so as to increase rigidity against a force from the vertical direction. Therefore, for example, when reaching the platform of the lifting cage where the weight load from above on the connecting part with the lifting device of the boarding / alighting device reaches the platform, the weight load is mainly received by the pair of upper shrimp brackets However, as described above, at least one of the upper shrimp metal fittings is composed of the shrimp gold and the receiving metal with the width direction oriented vertically, so that both the upper shrimp metal fittings are shrimp with the width direction oriented horizontally. The deformation of the upper shrimp metal fitting due to the weight load can be reduced as compared with the case of using gold and a receiver.

Connection between a pair of lower shrimp metal fittings 76 composed of shrimp gold 74 and catch 75 that are horizontally oriented, a connection side of the lift device 15 of the boarding / unboarding device 14, and the boarding / shipping device 14 of the lift device 15 A pair of upper shrimp metal fittings which are arranged between a portion above the installation position of the pair of lower shrimp metal fittings 76, and one of which is a shrimp gold 74 and a receiving metal 75 whose width direction is perpendicular to the vertical direction. 77 (FIGS. 10 and 11).

  Among these, as shown in FIG. 7 and FIG. 9, the specific arrangement position of the pair of lower shrimp metal fittings 76 is such that the pair of receivers 75 is in the vicinity of the lifting device connection region A of the first carriage 18. , Are upper surfaces of brackets 78 disposed at both end portions on the Y1-Y2 side. The position of the shrimp gold 74 of the lower shrimp metal fitting 76 on the X2 side is the upper surface of the bracket 79 projecting in the X2-Y2 side corner of the second carriage 35 toward the X2 direction. The arrangement position of the shrimp metal fitting 74 of the lower shrimp metal fitting 76 is the upper surface of the Y2 side portion 80 of the connection bracket 37 arranged on the X1-Y2 side of the second carriage 35. Each shrimp gold 74 has a general structure. That is, a spring 84 is provided at the base of a lever 83 for connection operation that has a main body frame 81 that is long in the Y1-Y2 direction and is connected by a pair of rotating pins 82 that are spaced apart from each other in the Y1-Y2 direction. This is an articulated metal fitting to which the attached connecting piece (connecting ring) 85 is fixed (FIGS. 10 and 11). It is called shrimp gold because its appearance is similar to shrimp. Each receiver 75 is a metal fitting in which a base portion of a hook 87 is integrally formed on the upper surface of an elongated rectangular base plate 86. The structure of the upper shrimp metal fitting 77 is the same as that of the lower shrimp metal fitting 76.

  Further, as shown in FIGS. 7, 8, 10, and 11, the specific arrangement position of the pair of upper shrimp metal fittings 77 is such that the receiving metal 75 of the upper shrimp metal fitting 77 on the X1 side is the first mount 17. This is a surface on the X1 side of the bracket 88 fixed immediately below the corner on the X1-Y1 side of the platform 23. Further, the position of the shrimp gold 74 with the width direction of the upper shrimp metal fitting 77 on the X1 side oriented in the vertical direction is the surface on the X1 side of the upper end portion of the support column 89 disposed on the X1-Y2 side of the second gantry 34. is there. On the other hand, the installation position of the catch 75 of the upper shrimp metal fitting 77 on the X2 side is the upper surface of the bracket 90 fixed to the corner on the X2-Y1 side of the platform 23 of the first gantry 17. In addition, the installation position of the shrimp gold 74 with the width direction of the upper shrimp metal fitting 77 on the X2 side oriented in the horizontal direction is the upper surface of the support column 39 disposed on the X2-Y2 side of the second mount 34.

  The lower shrimp metal fittings 76 and the upper shrimp metal fittings 77 are formed on the positioning structure 70 with the positioning structure 70 as a center in a state in which the surface of the first frame 17 on the connection side with the second frame 34 is viewed in plan view. A pair of upper and lower sides are arranged on both sides. With this configuration, for example, when an external force is applied to the lifting device 15 for some reason, most of the external force is the most at the site where the external force is applied among the lower shrimp metal fittings 76 and the upper shrimp metal fittings 77. It can be received with the nearby shrimp brackets 76 and 77. Thereby, for example, compared with the case where the shrimp metal fittings 76 and 77 are arranged in the inner space of the pair of positioning outer fitting members 72 constituting the positioning structure 70, the lifting device 15 and the boarding / unboarding device 14 by the external force are used. Damage to the connecting portion is reduced. In addition, damage to the positioning structure 70 due to the action of the external force can be prevented.

  1 and 2, reference numeral 100 denotes an opening / closing door that opens and closes a wheelchair entrance / exit on the lifting / lowering device 15 side of the platform 23 and a healthy person entrance / exit on the staircase 26 side. 3-6, the code | symbol 101 is mounted in the 2nd trolley | bogie 35, and the control panel which controls the electric system of the raising / lowering apparatus 15 is provided, the code | symbol 102 is provided in the 2nd mount 34, and the raising / lowering operation button of the raising / lowering apparatus 15 is shown. And so on.

Next, with reference to FIGS. 1-11, the usage method of the barrier-free boarding / disembarking ship installation 10 concerning Example 1 of this invention is demonstrated.
After the ferry 12 arrives at the quay 11, the operator uses the corresponding first and second carts 18 and 35 to store the boarding and unloading device 14 and the lifting device 15 stored in the turret storage area of the quay 11. While pushing each one, move to the vicinity of the ferry 12 on the quay 11. Then, the slope 13 is bridged between the ferry 12 and the boarding / alighting device 14 by hooking the tip of the slope 13 on the boarding board of the ferry 12.
Next, by using the positioning fitting structure 70, the lifting device 15 is positioned in the lifting device connection area A of the boarding boat device 14, and the positioned lifting device 15 is boarded and boarded by the connection structure 71. Connected to device 14. Specifically, the pair of positioning outer fitting members 72 and the pair of positioning inner fitting members 73 are widened so that the separation width gradually increases toward the tip of the positioning outer fitting member 72. By fitting an inner inclined surface and a tapered outer inclined surface whose corresponding width gradually decreases toward the tip of the corresponding inner inclined member 73 as a guide surface for positioning. The lifting device 15 and the boarding / alighting device 14 are positioned.

After the positioning, the elevating device 15 is connected to the boarding / alighting device 14 via the pair of upper shrimp metal fittings 77 and the pair of lower shrimp metal fittings 76 of the connection structure 71. Specifically, by hooking each shrimp gold 74 to the corresponding receiving metal 75, the connecting side of the boarding / unloading device 14 to the lifting / lowering device 15 is fixed to the side of the lifting / lowering device 15 connecting to the boarding / unloading device 14. The
At this time, the shrimp gold 74 of the upper shrimp metal fitting 77 on the X1 side has the width direction oriented vertically. Therefore, for example, when the lifting cage 41 reaches the platform where the weight load from the upper side with respect to the connecting portion of the boarding / alighting device 14 with the lifting device 15 reaches the platform, the weight load is mainly generated by the pair of upper shrimp metal fittings 77. However, since the upper shrimp metal fitting 77 on the X1 side has the shrimp gold 74 with the width direction oriented vertically as described above, both the upper shrimp metal fittings 77 have the width of the shrimp gold 74. Compared to the case where the direction is horizontally oriented, the deformation of the upper shrimp metal fitting 77 due to the weight load is reduced.

  Thus, after connecting the lifting / lowering device 15 to the boarding / unloading device 14, a person boarding the ferry 12 climbs the stairs 26 and rises to the platform 23, and enters the boarding / alighting deck of the ferry 12 through the slope 13 (FIG. 1). And FIG. 2). On the other hand, a physically handicapped person or the like riding in a wheelchair gets on the lifting cage 41 landing on the quay 11 of the lifting device 15 with the assistance of an assistant or by his / her own force, and goes up to the platform 23 by the cage lifting / lowering means 42. Cross the slope 13 and get on the ferry 12. These boarding procedures are reversed in the boarding procedure of the passenger who is going to get off the ferry 12 to the quay 11. In this way, a wheelchair user can use the lifting device 15 to perform a barrier-free boarding / disembarking ship.

In addition, since the second carriage 35 has a U shape with the opening side facing the entrance / exit side when the second mount 34 is lowered in plan view, the ground is The bottom plate 51 of the lifting cage 41 is grounded to the quay 11 without causing a step corresponding to the height of the second carriage 35 between the lifting platform 41 and the lifting cage 41, and smoothly through the entrance when the second mount 34 is lowered. A wheelchair can get on and off the lift cage 41.
Furthermore, since the boarding / disembarking device 14 and the lifting / lowering device 15 are provided so as to be movable separately from each other and are configured to be connected and integrated only during boarding / disembarking, the operator pushes when the boarding / exiting facility 10 moves. The weight of a single object to be reduced is reduced. As a result, it is easy to move the boarding / alighting facility 10 by human power, and the lifting / lowering cage 41 is swayed and the lifting / lowering apparatus 15 is overturned, which is a concern when the lifting / lowering device 15 is lifted / lowered from the boarding / unloading device 14. The unexpected situation is eliminated, and the stability of the elevating device 15 when getting on and off a wheelchair can be achieved.

In addition, as a countermeasure when the ground of the quay 11 is slightly inclined or uneven, a lifting / lowering device 15 is provided with an opening / closing control device (not shown) for the outer door 60 so that the wheelchair can get on and off the cage when landing on the cage. You may make it improve property (FIG. 5). Here, the opening / closing control device is provided with the electric lock means 110 of the outer door 60 in the elevating cage 41, and a pair of landing sensors 111 are disposed at both ends of the bottom plate 51 on the X1-X2 side on the descending entrance / exit side. In addition, an overload sensor 112 is provided in the elevating motor 47, and an outer door opening / closing control circuit is provided in the control panel 101 incorporating the microcomputer. At the time of the landing of the cage, the overload sensor 112 of the elevating motor 47 detects the landing of the bottom plate 51 that moves up and down horizontally, and the bottom plate 51 stops. At this time, if a landing signal is transmitted from both landing sensors 111 to the CPU of the control panel, the CPU estimates that the bottom plate 51 has landed parallel to the ground of the quay, and the CPU locks the outer door 60 to the electronic lock means 110. Send a release command. Thereby, the wheelchair user can safely go up and down to the lift cage 41 through the descending entrance and exit.
At this time, for example, even if there is a slight inclination or unevenness in the cage grounding portion of the quay 11 and the portion on the Y2 side of the bottom plate 51 is lifted from the ground, the lifting cage 41 has the self of the worm gear as described above. Since the braking force acts, the height position of the bottom plate 51 in the horizontal state at the time of ground contact is maintained. That is, the bottom plate 51 can safely get on and off the lift cage 41 of the wheelchair as long as the side (end) on the descending entrance / exit side is grounded.
However, when one or both of the ground sensors 111 do not detect the ground state of the bottom plate 51, the ground plate 51 is in contact with the bottom plate 51 in a part or all of the end portion of the bottom plate 51 on the Y1 side. There is a gap between the ground. At this time, safe getting on and off the bottom plate 51 of the wheelchair is not ensured. Therefore, this open / close control device is configured to increase safety by issuing an alarm from an alarm device provided in the lifting device 15 based on a command from the CPU of the control panel and alerting the user. Yes.
