Description

  The present invention relates to a platform movable fence device provided at a front end edge of a platform.

In a typical example of a door support structure for a movable platform device for a platform according to the prior art, a door that opens and closes is supported by a linear guide (for example, see Patent Document 1).
Such a linear guide is generally composed of a rail part and a slide block. However, a member to be attached to each requires a high-precision mounting surface. It became a factor that decreased reliability.
Further, even when the accuracy of the mounting surface is good, the same phenomenon occurs due to deformation and distortion of the entire frame due to the load. The apparatus disclosed in Patent Document 1 is also a system for minimizing the influence on the linear motion guide due to such accuracy and distortion.
The linear motion guide is very sensitive to dust and foreign substances from the external environment. If such a material enters the slide block, it may reach the end of its life, so the slide block has a seal structure. It was necessary to prevent the entry of foreign matter.

The output of the drive motor 5 for opening and closing the doors 2A and 2B is obtained by driving the toothed belt 8 via pulleys 6 and 7 attached to the frame 1 and the doors 2A and 2B. Is transmitted to the bracket 9 attached to the doors 2A and 2B, and the rollers 2a and 3b and the rollers 3c and 3d are moved on the guide rails 4a and 4b and 4c and 4d4 by this driving force. It is supported so as to be rotatable and can be opened and closed.
The drive motor 5 is disposed outside the guide rails 4a and 4b in the vertical direction, so that the device configuration can be made compact as a whole.

  As shown in FIG. 1 and FIG. 2, when the doors are two left and right as the doors 2A and 2B, the rail 4 is arranged at the center, so the lower rail of the right door 2B and the upper rail of the left door 2A are The doors 2A and 2B can be applied in common as a single mold rail 4b.

  FIG. 1 shows an open state of the doors 2A and 2B, and FIG. 2 shows a closed state in which the two doors 2A and 2B come out at the same time and the fence is closed (if necessary, the door can be opened and closed only on one side). .

In the embodiment according to the present invention, by adopting such a structure, high-precision processing / assembly required for the linear motion guide is not required, and it is difficult to be affected by the distortion of the door or the frame as the mounting member. The load burden and rigidity expected by the guide are ensured, and a compact movable fence device for the platform can be provided.
In addition, the linear motion guide is extremely sensitive to dust from the environment and requires a seal structure. However, it is not easily affected by dust, and the rails are angled so that no foreign matter remains, or dust, etc. It is easy to wipe off even if it adheres to the surface and has good maintainability.

  According to the embodiment of the present invention, the guide rails 4a and 4b that linearly guide the opening and closing movement in the extending direction of the doors 2A and 2B arranged in an upright state with respect to the platform PF, and the doors 2A and 2A, A plurality of rollers 3a and 3b provided in 2B, and the guide rails 4a and 4b are provided with a guide portion MS having a mountain-like cross section, and have a convex cross section protruding in the vertical direction. The roller rollers 3a and 3b are arranged as a configuration, and the outer peripheral surfaces of the rollers 3a and 3b are used as concave engagement surfaces provided with valley grooves VC having a V-shaped cross section. Since the guide rails 4a and 4b guide the opening and closing movements of the doors 2A and 2B, high-precision processing and assembly are unnecessary, and distortion of mounting members such as doors is prevented. Shadow The burden and rigidity of the load is ensured without receiving can maintainability also give the movable fence unit for good platform.

  Further, according to the embodiment of the present invention, in the configuration in the preceding paragraph, the guide rails 4a and 4b are arranged at the center in the vertical direction close to the center of gravity of the doors 2A and 2B arranged in an upright state with respect to the platform PF. Because it is arranged correspondingly, high precision processing and assembly are unnecessary, load burden and rigidity are secured without being affected by distortion of mounting members such as doors, maintenance is good, and the door Is supported near the position of the center of gravity, and a movable fence device for a platform that can smoothly open and close the door can be obtained.

  Furthermore, according to the embodiment of the present invention, the drive motor 5 for opening and closing the door is moved up and down with respect to the guide rails 4a and 4b arranged corresponding to the central portions in the vertical direction of the doors 2A and 2B. Because it is arranged outside the direction, high precision processing and assembly are unnecessary, load burden and rigidity are secured without being affected by distortion of mounting members such as doors, and maintenance is good, A movable fence device for a platform that can be configured in a compact configuration can be obtained.

  According to the embodiment of the present invention, in any one of the configurations of the preceding three items, the common guide rails 4b for respectively guiding the doors 2A and 2B that make a pair movable in opposite directions are provided. High-precision processing and assembly are not required, load load and rigidity are secured without being affected by distortion of door and other mounting members, maintenance is good, and the guide rail is a pair of doors. By making it common, the movable fence apparatus for platforms which can be set as a compact structure can be obtained.

In the embodiment according to the present invention, the following configuration is proposed.
(1) At least two rollers having valley grooves are arranged for one door, and a rail having a mountain shape for guiding the rollers is arranged at the center of the door.
(2) The door opening / closing drive motor is arranged outside the guide in the center of the door.
(3) When the door is a pair of left and right doors, one of the left and right door rails is integrated, and the platform movable fence device.
This configuration eliminates the need for high-precision processing and assembly required for linear motion guides, makes it less susceptible to distortion of doors and frames that are mounting members, and increases the load burden and rigidity expected of linear motion guides. A movable platform fence device that is secured and compact can be provided.
In addition, the linear motion guide is extremely sensitive to dust from the environment and requires a seal structure. However, it is not easily affected by dust, and the rails are angled so that no foreign matter remains, or dust, etc. It is easy to wipe off even if it adheres to the surface and has good maintainability.

It is a side view which shows the structure in the door open state of the movable fence apparatus for platforms in embodiment by this invention. It is a side view which shows the structure in the door closed state of the movable fence apparatus for platforms in embodiment by this invention. It is sectional drawing in the III-III line of FIG.
