Abstract
Description
The present invention relates to a sliding door link device that can be applied to an entrance door of an electric train or a screen door of the platform, and more particularly, to an improved sliding door type opening / closing device suitable for an environment requiring a small installation space, ≪ / RTI >
Electric trains have several sets of doors for each vehicle, and a screen door is also provided in the platform to correspond to the doors of each vehicle. The door for a train or the screen door of the platform is a sliding door made up of two pairs which are opened and closed in both right and left directions, and the plurality of sets are opened / closed at once by remote control.
BACKGROUND ART [0002] A sliding door opening / closing apparatus such as a door for a train or a screen door has been mainly applied to a hydraulic or pneumatic type wire or a belt driven type as its driving means. However, the hydraulic or pneumatic type includes solenoid valves for controlling the hydraulic pressure or pneumatic pressure generated by the compressor and hydraulic or pneumatic pressure generated by the compressor, and hydraulic or pneumatic actuators for moving the door in the open / Etc., are expensive and expensive to install and maintain. In particular, there is a lot of noise when the door is opened and closed. The wire or belt driven type requires a motor that generates power, a drive pulley that is rotationally driven by the power of the motor, a driven pulley disposed between the drive pulley and the door opening / closing interval, and a wire or belt wound between the drive pulley and the driven pulley , It is not easy to install and adjust, and it is frequently broken due to overload, etc., and it is difficult to control the opening / closing accurately because of low response characteristic.
On the other hand, the inventor of the present invention has proposed a feed screw driving method using a lead screw and a lead nut as driving means of a screen door opening / closing apparatus through Utility Model Registration No. 20-0426905. The feed screw driving method of the line registration design uses the motor as the driving source and uses the lead screw and the lead nut which convert the rotational motion of the motor shaft into the linear motion and the response speed of the screen door opening and closing control is fast and accurate, And convenience, and also provides an economical effect on the maintenance due to a small number of failures.
In recent years, there has been a tendency to use a feed screw driving method which is advantageous for many doors of electric trains, and there is an increasing demand for retrofitting a conventional electric train door by a feed screw driving method. The door for the electric train is controlled in the same manner in synchronization with the screen door of the platform, so that the device such as the line registration scheme as described above can be applied as it is.
However, in the case of retrofitting an old aged electric train door, since the space for installing the opening and closing drive mechanism such as the lead screw and the guide roller bracket is much narrower than that of the screen door, There is no problem.
Generally, in a feed screw driving method, a link device flexibly and flexibly responding to warping or fluctuation is essential because it may be mechanically restrained by bending of a feed screw or jiggling of a door, and opening and closing may not be smooth. The link device must also be of a structure capable of accommodating the flow in all directions except the opening and closing directions. However, the conventional link device occupies a lot of space as a refracting link, and in particular, a mounting width for accommodating the refracting posture is relatively large. Therefore, improvement of the refracting links is required in a conventional electric train in which the installation space, especially the space of the installation space, is narrow.
It is an object of the present invention to provide an improved sliding door link apparatus capable of minimizing the installation width of the entire apparatus so as to be suitable for an environment with a narrow installation space.
According to an aspect of the present invention, there is provided a sliding door link apparatus including a lead nut coupled to a lead screw that is driven to rotate and linearly moving along a rotation of the lead screw, A nut holder for connecting the door of the structure supported by the bracket to the lead nut, the nut holder being connected to and fixed to the lead nut and having a protruding portion extending vertically downward; And a pivoting means for pivotally supporting the link member with respect to the roller bracket so as to be pivotally moved in a line parallel to the opening and closing directions, Two pivot members for supporting the link member on both sides as pivoting means, Wherein one of the pivotal members has a bolt-shaped threaded portion and is movable in the opening and closing direction while receiving the linking member and allowing the pivotal member to move together while restricting the two pivotal members in a penetrating state, A pivot support block fixed to the roller bracket and supporting the two pivot members protruding through the link holder so as to pass through the pivot support block so as to be movable in the opening and closing direction, And an adjustable nut fastened to the threaded portion so as to adjust the horizontal position of the door relative to the lead nut position.
delete
Further, the sliding door link apparatus according to the present invention is characterized in that it has a structure in which a lead nut coupled to a lead screw that is driven to rotate and linearly moves along its rotation is provided, and a door is suspended from a roller bracket A nut holder for connecting the door of the nut holder to the lead nut, the nut holder having a projecting portion connected to the lead nut and moving together and extending vertically downward, And a pivoting means for pivotally supporting the link member with respect to the roller bracket in a line parallel to the opening and closing directions, wherein the lead nut is supported by the nut holder And has a hole for fastening the bolt element passing through the hole It may be provided as a configuration provided with a heli-coil yoke (heli coil) that can be mounted is elastically fastened to the bolt element.
The sliding door linking device according to the present invention is a structure for absorbing the flow between the driving means and the door on the vertical plane with respect to the center of the lead screw and can be installed within the same width as the door thickness .
Further, according to the sliding door link apparatus of the present invention, since the axis center of the lead screw of the driving means and the center of the orbit of the roller for guiding the movement of the sliding door can be arranged on the same vertical plane, Width can be minimized.
Therefore, the present invention provides an effect of improving the safety and performance of the existing aged electric train doors by introducing the feed screw driving method to the doors of the existing electric trains having a narrow installation space.
Meanwhile, the present invention can reduce the installation width of the opening and closing devices for sliding doors of screen doors of other platforms as well as electric trains, thereby enhancing the space utilization of each structure. In addition, the installation space is very narrow, It is also very useful for elevator doors where opening and closing control is particularly required.
Hereinafter, a sliding door supporting apparatus according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
It should be understood that the present invention is not limited to the embodiments described above, but may be applied to other types of buildings such as a screen door provided at the platform, It goes without saying that the present invention can be applied to sliding doors and door openers. It is to be understood that the drawings are only for the understanding of the present invention, and some elements may be exaggerated or omitted.
