Description

  The present invention relates to a side sliding door device for opening and closing a passenger entrance of a railway vehicle, mainly a commuter train, and more particularly, in a side sliding door device of a suspension system, including a door cart that runs along a rail provided on a vehicle body side. The present invention relates to an apparatus provided with a mechanism that makes it possible to adjust the position of a side sliding door not only in the vertical direction but also in the thickness direction (direction of sleepers) with respect to the door hanging metal (also referred to as a door hanging bracket).

  For example, with reference to FIG. 1 showing an embodiment of the present invention, the side sliding door device for a railway vehicle is a double sliding side sliding door device in which both side sliding doors 2 are provided on both sides of the passenger entrance A. 3 is opened by moving into the doorway 3 from the door pockets 3 on both sides to the entrance / exit A side and closed. Above the doorway A on the vehicle body side, a pair of upper rails 4 are arranged in the front and rear directions above the doorway A from inside the door pockets 3 on both sides, with a distance in the front-rear direction of each side sliding door 2. The door 6 of the attached door hanging bracket 5 is placed on the rail 4, and is opened and closed with the side sliding door 2 suspended from the rail 4 via the door wheel 6. In the side sliding door device of FIG. 1, the mounting position of the rail 4 with respect to the vehicle body is configured to be adjustable in the vertical direction and the thickness (sleeper) direction.

  By the way, in the case of a railway vehicle, a vehicle body on which side sliding doors are provided is manufactured in advance, including passenger doorways and doors on both sides thereof arranged at a predetermined distance in the front-rear direction. The rails are also installed on the vehicle body side in advance. Then, in a state where each side sliding door is fitted into the vehicle body from the doorway, each side sliding door is mounted on the rails above the doorway with the door carriages of the front and rear door hanging brackets and incorporated in the vehicle body. For this reason, when taking into account manufacturing errors of the vehicle body, deformation of the vehicle body when passengers get in, or installation of heavy equipment under the floor, etc., the side sliding door's vertical direction and thickness with respect to the rail when installing the side sliding door Adjustment of the position in the direction is required. In particular, when the side sliding door is moved into the door pocket and opened when the passenger doorway is opened, the passenger's finger is caught in the gap between the side sliding door 2 and the columnar frame 3b at the door pocket entrance (see FIG. 2A). Since there is a fear, adjustment work of the gap between the two requires skill and takes time.

  Further, as shown in FIG. 2 (a), the side sliding door 2 is suspended from an upper rail 4 via a door hanging bracket 5 so as not to be removed even if pushed by a passenger in the vehicle, while a floor surface (shoe shoe). A rail 14 is also installed on the 37 side, and a concave groove 2 b at the lower end of the side sliding door 2 is fitted into the lower rail 14. However, for example, if the concave groove 2b at the lower end of the side sliding door is not caught on the lower rail 14, the lower end of the side sliding door is likely to be detached from the lower rail 14. Moreover, it is necessary to adjust so that the clearance of several millimeters may be left between the lower end of the side sliding door 2 and the floor surface (shoe shoe) 37 on which the lower rail 14 is laid. Thus, conventionally, a side sliding door device is known in which, for example, the mounting positions of the door hanging brackets that are mounted before and after the upper end of the side sliding door can be adjusted in the vertical direction.

  As a prior art related to this type of side sliding door device, the trolley axle is a reamer bolt, which is fitted into a reamer hole provided in the door suspension metal, and fastened with a hard lock nut and fixed between the door carriage and the door suspension metal. There has been proposed an apparatus having a structure in which a spacer is interposed and one end surface of the spacer is pressed against an end surface of an inner race of a rolling bearing by a tightening force of the hard lock nut (see, for example, Patent Document 1).

As another prior art related to the side sliding door device, a sliding door is formed by attaching a surface plate to both the inside and outside of the bone frame body composed of upper and lower horizontal bones and left and right vertical bones, and a suspension door wheel is pivotally supported at the upper end of the sliding door. In the hanging sliding door for a vehicle provided with the door suspension metal, the door suspension metal is formed in a horizontally long plate shape having substantially the same length as the upper lateral bone of the bone frame body, and is integrated with the upper lateral bone. An apparatus having a structure formed in the above has been proposed (see, for example, Patent Document 2).

However, the conventional side sliding door device described above has room for improvement in the following points. That is,
-To change the position of the side sliding door in the vertical direction, the fixing screw of the upper rail is loosened, and the position of the upper rail relative to the side sliding door is adjusted in the vertical direction relative to the long hole of the rail. During this time, the side sliding door must be supported so as not to descend by its own weight, or the side sliding door must be removed once, and several workers are required for the vertical adjustment work. Also, after adjusting the vertical position of the side sliding door with respect to the upper rail, it is necessary to tighten the fixing screws once loosened, and during that time, the position of the side sliding door must be firmly supported. It takes time and effort.

  The adjustment of the position of the side sliding door in the thickness direction (sleeper direction) is performed by inserting / removing a thin liner in the gap between the mounting surface of the upper rail and the rail. Therefore, skill is required for the adjustment work, and it is necessary to support the side sliding door so as not to descend by its own weight, or to remove the side sliding door once, which takes time.

  -When equipped with an adjustment mechanism in the vertical direction or thickness direction of the side sliding door relative to the door suspension, there is no space between the side sliding door or door suspension and the vehicle body, so it is incorporated in the door suspension. It is desirable. Moreover, it is necessary to prevent the side sliding door and its peripheral parts (other than the door hanging metal) from being processed as much as possible.

  The present invention has been made in view of the above points, and in a state where the side sliding door is suspended from the upper rail, that is, the side sliding door is not supported by the operator, and the side sliding door can be easily operated. On the other hand, it is an object to be solved to provide a railcar side sliding door device that can be accurately and surely adjusted by moving in the vertical direction and thickness direction, and that can greatly reduce the adjustment time.

  In order to solve the above-described problems, a railcar side sliding door device according to the present invention is arranged so as to sandwich a railroad car that is movably mounted on a rail provided above a passenger entrance of the railcar and the rail. At least two door suspension brackets that pivotally support the auxiliary vehicle supported by the door can be adjusted in the vertical direction and thickness direction with respect to the upper end of the side sliding door at a distance in the front-rear direction of the side sliding door. A side sliding door device for a railway vehicle of a suspension system provided, wherein the door hanging bracket is slid in a thickness direction on an upper surface of a mounting member that is integrally fixed to an upper end portion of the side sliding door via a mounting bolt. Place the screw freely in the screw holes provided on both sides of the fixed plate that is erected upward from the upper end of the mounting member at a position corresponding to each door hanging bracket. Ma The abutment plate provided integrally with the door hanging bracket is brought into contact with the end of the push screw, and a pulling screw penetrating both sides of each fixing plate is directly attached to the door hanging bracket or to the backing plate. The side sliding door elevating mechanism is interposed between the door suspension fittings and the attachment member, and the door suspension fitting is configured to be integrally connectable to the attachment member together with the elevation mechanism by the attachment bolts. It is characterized by that.

  According to a second aspect of the present invention, each of the elevating mechanisms is screwed into both side screw portions of a screw shaft (turnbuckle type) screw screw that is disposed below each door hanging bracket and is reversely threaded to one side of the screw shaft. A pair of moving taper blocks that approach or move away from each other by rotation of the door, and a pair of fixed tapers that are fixed on both sides of the lower surface of the door-hanging bracket and have a tapered surface that slidably contacts the taper surface of each moving taper block It is desirable that a taper block is provided, and the door hanging bracket is raised or lowered with respect to the mounting member by rotation of the screw shaft to one side.

  According to a third aspect of the present invention, each of the elevating mechanisms passes downward through a mounting seat integrally connected to a lower end of each door hanging bracket, is screwed to a mounting member at the upper end of the side sliding door, and rotates to one side. And a vertical adjustment bolt that raises or lowers the side sliding door, and teeth (rack) that are arranged on both sides of the door hanging bracket and that are continuous in a saw blade shape in the vertical direction, A pair of supports fixed on the mounting member at the upper end of the sliding door, and extending downward from both sides of each door hanging bracket, continuous in a saw blade shape in the vertical direction, facing the teeth of the support A locking member provided with meshable teeth (rack), and a fastening bolt that passes through each locking member and is screwed to the support body, and can connect the door suspension fittings to the support body via a backing plate. It is desirable to provide.

  Since the railcar side sliding door device according to the present invention has the above-described configuration, it has the following excellent effects.

  According to the side sliding door device according to the first aspect, the side sliding door is suspended integrally with the mounting screw via the mounting member fixed to the upper end of the door hanging bracket, so that the mounting screw is loosened. In other words, if the relative position of the side sliding door is adjusted without completely removing the mounting screw, there is no need for the operator to support (hold) the side sliding door during work or to remove the side sliding door once. The burden on the operator is small, the number of workers can be reduced, and the work becomes easy. Also, the lifting mechanism is provided between the door hanging brackets, and the adjustment screws in the thickness direction (push screws and pulling screws) are placed sideways (sleeper direction) on the fixing plate that stands on the mounting member. The member for position adjustment does not protrude from the sliding door and the door hanging metal fitting, and therefore, the side sliding door and its peripheral members are not required to be processed. Furthermore, the adjustment of the side sliding door in the thickness direction is performed by rotating the other screw in a state where the push screw or the pulling screw is loosened, so that the door hanging bracket moves relative to the side sliding door. Then, the mounting screw is tightened and fixed. Furthermore, by tightening the loosened screw, it can be firmly fixed in the adjusted state. During this time, the time required for the adjustment work is about 5 minutes, which is significantly shortened compared to the conventional case.

  According to the side sliding door device according to claim 2, by rotating the central part of the screw shaft of the turnbuckle type in one direction, the moving taper blocks on both sides facing each other are separated from or approach each other, and the fixed taper block The door hanging bracket is pushed up or down with respect to the side sliding door. Thereby, the position of the up-down direction with respect to a door hanging metal fitting is adjusted for a side sliding door. In addition, each door hanging bracket has a predetermined width, and the fixed taper blocks on both sides arranged at a predetermined distance on the lower surface side are raised and lowered simultaneously in the vertical direction at the same time. Is raised and lowered accurately in a substantially vertical direction with respect to the side sliding door. Incidentally, the time required for the adjustment work during this period is usually about 3 minutes, which is greatly reduced compared to the conventional case.

  According to the side sliding door device according to the third aspect, when the left and right fastening bolts are loosened in a state where the mounting bolts on both sides are loosened, the respective supports on the mounting member are separated from the locking members, and are formed in a saw blade shape. Engagement between racks, which are continuous teeth, is eliminated, and the racks are opened. In this state, when the vertical adjustment bolt is loosened, the side sliding door descends according to the number of rotations of the vertical adjustment bolt with respect to the door hanging bracket by its own weight. On the other hand, when the vertical adjustment bolt is tightened in the above state, the side sliding door rises according to the rotational speed of the vertical adjustment bolt against the door suspension metal against the dead weight of the side sliding door. After adjusting the vertical position in this manner, the left and right fastening bolts are tightened to engage the racks, and then the mounting bolt is tightened to fix the support on the mounting member. Rack) can be easily adjusted for each pitch.

  Embodiments according to the side sliding door device of the present invention will be described below with reference to the drawings.

A pair of support bodies 22 are arranged on both sides of the mounting member 21 so as to sandwich the door-hanging metal fitting 5 ′, and the mounting bolts 10 are inserted into holes 22 a penetrating through the central portion of the respective support bodies 22. A screw portion 10 a that protrudes downward from the ten support members 22 is screwed into a screw hole 21 a of the attachment member 21, and each support member 22 is fixed to both sides on the attachment member 21. On the inner wall of each support 22, a rack 22 b made of saw-tooth teeth that are continuous in the vertical direction is formed. A locking member 24 provided on the outer surface with a rack 24b made of saw-tooth teeth corresponding to the rack 22b is integrally extended downward on both sides of the door suspension fitting 5 '.

  An inverted U-shaped opening 24a is provided at the lower portion of each locking member 24, and a lateral fastening bolt 23 that penetrates the contact plate 25 protrudes outward through the opening 24a. A screw hole 22c is formed in the inner wall (rack) 22b of each support member 22 so as to face the through hole 22a, and the screw portion 23a of the fastening bolt 23 is screwed into the screw hole 22c, and is attached to the rack 22b. A locking member 24 is integrally connected to the support 22 in a state where the rack 24b is engaged. With this structure, the door hanging bracket 5 ′ is attached to both sides of the upper end portion of the side sliding door 2. Further, a vertical adjustment bolt 27 is inserted downward into a through hole 26a of a mounting seat 26 formed integrally with the lower end of the door hanging bracket 5 '. The adjusting bolt 27 protrudes downward from the mounting seat 26 and is screwed into a small diameter screw hole 21 b provided in the mounting member 21. Since other configurations are common to the above-described embodiment, common members are illustrated using the same reference numerals, and description thereof is omitted.

  As described above, the elevating mechanism of the side sliding door device 1 ′ according to the embodiment of the present invention is configured, and the adjustment work in the vertical direction of the side sliding door device 1 ′ will be described with reference to FIGS. .

  With the mounting bolts 10 on both sides loosened, the left and right fastening bolts 23 are loosened. As a result, the support 22 is separated from the locking member 24 on the mounting member 21, and the rack 22 and the rack 24 are opened to cancel the meshing state. In this state, when the vertical adjustment bolt 27 is loosened, the side sliding door 2 descends according to the number of rotations of the vertical adjustment bolt 27 with respect to the door hanging bracket 5 ′ by its own weight as shown in FIG. 8. On the other hand, when the vertical adjustment bolt 27 is tightened in the reverse direction, the side sliding door 2 is pulled up according to the number of rotations of the vertical adjustment bolt 27 against the weight of the door hanging bracket 5 ′. However, in the case of this example, the pitch of the racks 22/24 is 1 mm, so the adjustment is made in units of 1 mm. Further, it can be accurately adjusted based on the number of rotations of the vertical adjustment bolt 27. After the adjustment, the left and right fastening bolts 23 are fastened to engage the rack 22 and the rack 24, and then the mounting bolt 10 is fastened to fix the support 22 on the mounting member 21.

  The side sliding door device of the present invention has been described above with reference to two embodiments, but can be implemented as follows.

  -The side sliding door 2 is not limited to a type that opens and closes two doors, but can be similarly applied to a case of a single door.

  A structure in which two door hanging brackets 5 are attached to one side sliding door 2 is common, but the same applies to a case where three or more door hanging brackets 5 are attached.

  For the door engine 36, in addition to the above embodiment, for example, there is a method of rotating an arm by combining a rack and a pinion.
