Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a railway car window,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for replacing a windshield or an elevator door installed in a passenger car of a railway vehicle and more particularly to a windshield window for a railway car, Replacement device.

In general, railway vehicles including high-speed railway cars, electric trains, and general railways are equipped with lift doors for passengers to enter and exit, and windows for viewing outside scenes from inside the carriages. Here, the elevator door and the window are separated from the carriage for failure, breakage, replacement, or periodic inspection, and new parts are mounted at the separated positions. Conventionally, the operation of attaching and detaching the lift door and the window glass has been manually performed by a plurality of operators.

In view of this, a device for detaching a door (or an elevator door) has been developed, and this is disclosed in Korean Registered Utility Model No. 0423434 entitled "Door Entry / Exit Device for Electric Trains". As shown in FIG. 1, a rotating body 10 having a movable body 10, a base 11 fixed to the vehicle body 10, and a turntable 21 fixed to the base 11 and rotatably mounted thereon, Up and down operation means 30 having a joint portion 32 provided on an end portion of a pillar member 31 fixed to the turntable 21 and a vertical movement means 30 mounted on the pillar member 31 via a joint portion 32, Backward actuating means 40 having a fixed beam 42 to which the beam 41 is drawn or inserted and an inversion means 51 having an inversion lever 51 provided on the end of the slide beam 42 for axial rotation And a clamping unit 60 having a clamping plate 62 axially coupled by a reversing lever 51 and a hinge 61 so as to be axially rotated upward or downward. Here, the clamping means 60 further includes clamping jaws 63 installed at both side ends of the clamping plate 61 to grip the door D.

Therefore, when the vehicle body 10 moves to the vicinity of the door D and stops, the turntable 21 rotates, and the fixed beam 42 moves upward / downward via the joint part 32. Then, the slide beam 41 When the clamping plate 62 reaches the door D, the clamping jaw 63 grasps the rim of the door D by moving forward / backward. Of course, the gripped door D is moved to the next position by the operation of the turntable 21, the joint part 32, the slide beam 41, the clamping plate 62 and the clamping jaws 63.

However, since the carriage of a railway vehicle such as a train is located on a line much higher than the ground, the height of the column member 31 of the up-and-down operation means 30 must be high in order to grip the door of the carriage, There is a risk of accidental rollover.

Since the clamping jaw 63 grasps both end portions of the door D, the clamping means 60 can only grip the door D in a disassembled state and move it to the next position, The user can not grasp and support the door D in the state to do so. That is, while separating or installing the heavy door (D), the operator (D) must be supported by the operator or other equipment.

The clamping jaws 63 are suitable for gripping high strength and thick doors, and are unsuitable for work on members that are susceptible to breakage, such as window glass of a passenger car. Further, the window glass should be able to support the window glass in the installed state during the separation operation, but the clamping jaw 63 can not support the window glass.
