Description
[Technical Field]
[0001] The present invention relates to a railway vehicle and a manufacturing method thereof, and more particularly to a railway vehicle having a mounting structure for mounting interior items such as luggage racks to a body structure, and a manufacturing method thereof. [Background technology]
[0002] 11 and 12, a side structure 100a constituting the body of a railway vehicle 100 has a plurality of side entrances 100b formed at predetermined intervals, side windows 100c arranged between the side entrances, and interior fittings 100d such as long luggage racks 105 arranged above the side windows. Also, interior fittings 100d such as long hanging devices 107 are arranged on a roof structure 100e constituting the body of the railway vehicle 100. For example, the luggage racks 105 are composed of a plurality of luggage rack brackets 105a screwed to side inner ribs 101 and lining panels 103 constituting the side structure 100a at positions spaced apart at predetermined intervals in the fore-and-aft direction of the vehicle, and luggage rack bars 105b fixed to the luggage rack brackets 105a.
[0003] However, the side inner frame 101 and the lining plate 103 that make up the side structure 100a each have manufacturing errors, and assembly errors can also occur. Therefore, in order to install the luggage rack bracket 105a and the like in the correct position, it was necessary to perform work such as measuring the installation position correctly, marking, drilling holes, and threading the female screws, all in accordance with the actual vehicle to which the side inner frame 101 and the lining plate 103 had been installed. Specifically, screw seats 102 were fixed to the outside of the vehicle body of the assembled side inner frame 101, and pilot holes were drilled in the assembled interior panel 103, side inner frame 101, and screw seats 102, and female screw holes 104 were formed in the pilot holes.After that, the female screw holes 104 were aligned with the screw insertion holes 106a and 106b formed in the mounting seat 106 of the luggage shelf bracket 105a, and set screws 108 were inserted through the screw insertion holes 106a and 106b and fastened to the female screw holes 104, thereby attaching the luggage shelf bracket 105a to the side inner frame 101 and interior panel 103 in the correct position.
[0004] However, with the above-mentioned luggage rack 105 mounting structure, the screw seat 102 fixed to the outer side of the car body of the inner side frame 101 is not visible to the worker, making it difficult to grasp the position of the screw seat, which required the screw seat 102 to be made larger than necessary, which was structurally undesirable. Also, because the luggage rack 105 is mounted high, there is a problem that workers have to work upwards a lot, which places a heavy burden on them. Furthermore, drilling holes, machining female threads, etc. generates a lot of chips, which must be carefully cleaned up after the work, which increases the work time.
[0005] In order to address such problems, for example, Patent Document 1 discloses a method for fixing the problem, as shown in Figs. 13 and 14, in which screw insertion holes 201a, 202a are provided in overlapping relation in an interior panel 201 and a side inner frame 202 disposed on the outside of the vehicle body of the interior panel 201, and a screw insertion hole 203a of an interior part 203 (luggage shelf bracket) is aligned with the screw insertion holes 201a, 202a, and a set screw 204 is inserted from the interior part side into the screw insertion holes 201a, 202a, 203a. In a structure for mounting interior parts of a railway vehicle, in which interior parts 203 are attached by screwing into female screw holes 205a of screw seats 205 attached to the outer surface of the carbody of the side inner frame 202, a configuration is disclosed in which at least the screw insertion holes 201a, 202a of the interior panel 201 and the side inner frame 202 are formed with a larger diameter than the female screw hole 205a, a guide frame 206 is provided on the outer surface of the carbody of the side inner frame 202, and the screw seat 205 is slidably supported within the guide frame 206. With the above configuration, work such as drilling holes and processing female screws for actual car matching is eliminated, and the generation of chips can be avoided. [Prior art documents] [Patent documents]
[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2002-356162 Summary of the Invention [Problem to be solved by the invention]
[0007] However, in the mounting structure for railway vehicle interior fittings described in Patent Document 1, the screw insertion hole 201a of the interior panel 201 is hidden by the interior fitting 203, making it difficult for the worker to see, and there was a problem in that the screw fastening work of aligning the screw insertion holes 201a, 202a of the interior panel 201 and the side inner frame 202 with the screw insertion hole 203a of the interior fitting 203, inserting the set screw 204 into these screw insertion holes 201a, 202a, 203a from the interior fitting side, and fastening the inserted set screw 204 into the female screw hole 205a was time-consuming.
[0008] Furthermore, since the screw insertion holes 201a, 202a of at least the interior panel 201 and the side inner frame 202 are formed with a larger diameter than the female screw hole 205a, a guide frame 206 is provided on the outer surface of the carbody of the side inner frame 202, and the screw seat 205 is slidably supported within the guide frame 206, it is possible to adjust the attachment position of the interior part 203 in the front-to-rear direction of the car (rail direction) and the up-to-down direction of the car (car height direction) by sliding the screw seat 205 within the guide frame 206, but it is not possible to adjust it in the left-to-right direction of the car (sleeper direction). In other words, there is a possibility that manufacturing errors and assembly errors may occur in all directions (three-dimensional directions) of the car, such as front-to-rear, up-down, and left-to-right, but there has been a problem in that it is not easy to absorb those manufacturing errors and adjust the attachment position of the interior part to the correct position.
[0009] The present invention has been made to solve such problems, and aims to provide a railway vehicle having an interior accessory mounting structure that can eliminate work such as drilling holes and threading the body structure to fit the actual vehicle, can speed up screw fastening work, and can easily adjust the mounting position relative to the body structure in any direction, including front-to-back, up-down, and left-to-right, and a method for manufacturing the same. [Means for solving the problem]
[0010] In order to achieve the above object, a railway vehicle and a manufacturing method thereof according to the present invention have the following configuration. (1) A railway vehicle having an interior equipment mounting structure to be mounted inside the car body of the body structure, The mounting structure includes a fixing bolt fixed to the body structure and having a male thread portion protruding toward the inside of the vehicle body, a support plate inserted through the male thread portion of the fixing bolt from the inside of the vehicle body and formed so that an attachment position relative to the fixing bolt can be moved in a first direction along the attachment surface of the body structure, and a movable bolt supported by the support plate so as to be movable in a second direction perpendicular to the first direction and along the attachment surface of the body structure, and having a male thread portion for attaching a mounting seat for the interior part protruding from the support plate toward the inside of the vehicle body, The interior part is fastened to the support plate via the movable bolt, and the support plate is fastened to the body structure via the fixing bolt.
[0011] In this invention, the mounting structure includes a fixing bolt fixed to the body structure and having a male thread portion protruding toward the inside of the carbody, a backing plate inserted into the male thread portion of the fixing bolt from the inside of the carbody so that its mounting position relative to the fixing bolt can be moved in a first direction along the mounting surface of the carbody, and a movable bolt supported by the backing plate so as to be movable in a second direction perpendicular to the first direction and along the mounting surface of the carbody, the male thread portion for attaching a mounting seat for an interior part protruding from the backing plate toward the inside of the carbody, the interior part being fastened to the backing plate via the movable bolt and the backing plate being fastened to the body structure via the fixing bolt, so that the mounting position of the backing plate relative to the fixing bolt fixed to the body structure can be adjusted by moving the backing plate in the first direction along the mounting surface of the carbody, and the mounting position of the interior part relative to the backing plate can be adjusted by moving the movable bolt in a second direction perpendicular to the first direction and along the mounting surface of the carbody.Furthermore, the mounting position of the interior part relative to the body structure can be adjusted in a third direction perpendicular to the first and second directions by adjusting the thickness of the backing plate. Therefore, the mounting position of the interior equipment relative to the body structure can be easily adjusted in any direction, including front-rear, up-down, left-right, and so on.
[0012] In addition, since the mounting position of the interior part relative to the body structure can be easily adjusted in any direction, including front-to-rear, up-down, and left-to-right, work such as drilling holes and machining female screws to fit the body structure to the actual vehicle can be eliminated. Furthermore, since the interior part is fastened to the backing plate via a movable bolt whose male threaded portion protrudes toward the inside of the car body, and the backing plate is fastened to the body structure via a fixing bolt whose male threaded portion protrudes toward the inside of the car body, workers can fasten the interior part to the backing plate while checking the male threaded portion of the movable bolt protruding from the backing plate toward the inside of the car body, and can fasten the backing plate to the body structure while checking the male threaded portion of the fixing bolt protruding from the body structure toward the inside of the car body. Therefore, the work of fastening the screws of the interior part to the backing plate and the work of fastening the screws of the backing plate to the body structure can both be performed smoothly and quickly.
[0013] Therefore, according to the present invention, it is possible to provide a railway vehicle having an interior accessory mounting structure that can eliminate the need for work such as drilling holes in the body structure to fit the actual vehicle and machining female screws, and can speed up the screw fastening work, and can easily adjust the mounting position relative to the body structure in any direction, including front-to-back, up-down, and left-to-right.
[0014] (2) In the railway vehicles described in (1), A thickness adjusting liner is mounted between the mounting surface of the body structure and the mounting seat of the interior equipment.
[0015] In the present invention, a thickness-adjusting liner is attached between the mounting surface of the body structure and the mounting seat of the interior part, so the mounting position of the interior part relative to the body structure can be more easily adjusted in the direction perpendicular to the mounting surface of the body structure by adjusting the thickness of the thickness-adjusting liner. As a result, the mounting position of the interior part relative to the body structure can be more easily adjusted in all directions, including front-to-rear, up-down, and left-to-right, of the vehicle.
[0016] (3) In the case of a railway vehicle described in (1) or (2), the support plate comprises a first support plate arranged on the mounting surface side of the body structure and a second support plate arranged on the mounting seat side of the interior part, The first receiving plate is formed with a guide hole that supports the head of the movable bolt so that it cannot rotate while guiding it in a second direction, and the second receiving plate is formed with a screw insertion hole that inserts the male threaded portion of the movable bolt so that it can move in the second direction.
[0017] In the present invention, the backing plate comprises a first backing plate arranged on the mounting surface side of the bodywork and a second backing plate arranged on the mounting seat side of the interior part, and the first backing plate has a guide hole formed in it that supports the head of the movable bolt non-rotatably while guiding it in the second direction, and the second backing plate has a screw insertion hole formed in it through which the male threaded portion of the movable bolt is inserted so that it can move in the second direction.Therefore, by dividing the backing plate into a first backing plate with a guide hole formed in it that supports the head of the movable bolt non-rotatably while guiding it in the second direction, and a second backing plate with a screw insertion hole formed in it through which the male threaded portion of the movable bolt is inserted so that it can move in the second direction, the support structure for the movable bolt relative to the backing plate can be formed more easily.
[0018] That is, the first backing plate can be formed with a guide hole passing through it, and the second backing plate can be formed with a screw insertion hole passing through it, so two types of hole drilling can be performed separately on the first backing plate and the second backing plate. This makes it easier to form the support structure for the movable bolt on the backing plate. Also, the first backing plate has a guide hole that supports the head of the movable bolt so that it cannot rotate and guides it in the second direction. Therefore, when fastening an interior part to the second backing plate via the movable bolt, the guide hole can prevent the movable bolt from rotating, reducing the effort required for screw fastening work.
[0019] (4) In the railway vehicles described in (3), the interior equipment is a luggage rack equipped with a luggage rack bracket attached to a mounting plate fixed to the inside of the car body of the side inner frame of the side structure, the fixing bolt is fixed to the mounting plate, and the mounting seat of the luggage rack bracket is fastened to the movable bolt; The second support plate is formed so that the bracket main body extending from the mounting seat of the luggage rack bracket toward the inside of the vehicle body can be exposed, and the lower end of the side ceiling panel formed so that it can shield the mounting seat of the luggage rack bracket and the inspection window formed in the side structure can be fastened to it in an adjustable mounting position.
[0020] In this invention, the interior accessory is a luggage rack with a luggage rack bracket attached to a mounting plate fixed to the inside of the carbody of a side inner frame of the side structure, and the fixing bolt is fixed to the mounting plate and the mounting seat of the luggage rack bracket is fastened to the movable bolt. Therefore, the mounting position of the first and second support plates relative to the fixing bolt fixed to the mounting plate of the side structure can be adjusted by moving the first and second support plates in a first direction along the mounting surface of the mounting plate, and the mounting position of the luggage rack bracket relative to the first and second support plates can be adjusted by moving the movable bolt in a second direction along the mounting surface of the mounting plate that is perpendicular to the first direction. Furthermore, the mounting position of the luggage rack bracket relative to the mounting plate can be adjusted in a third direction perpendicular to the first and second directions by adjusting the plate thickness of the first and / or second support plate. Therefore, the mounting position of the luggage rack relative to the side structure can be easily adjusted in any direction, including fore-aft, up-down, and left-right, of the car.
[0021] In addition, the second support plate is formed so that the bracket main body, which extends from the mounting seat of the luggage rack bracket toward the inside of the car body, can be exposed, and the lower end of the side ceiling panel, which is formed so that it can shield the mounting seat of the luggage rack bracket and the inspection window formed in the side structure, is fastened to it so that the mounting position can be adjusted.Therefore, by removing the lower end of the side ceiling panel from the second support plate, it is possible to adjust the mounting position of the luggage rack relative to the side structure, and by attaching the lower end of the side ceiling panel to the second support plate, the mounting seat of the luggage rack bracket can be hidden, improving the appearance of the luggage rack to passengers.
[0022] In addition, the lower end of the side ceiling panel, which is formed to be able to cover the inspection window formed in the side structure, is fastened to the second support plate so that its mounting position can be adjusted, so there is no need to provide a separate cover for the inspection window and the side ceiling panel can also serve as a cover for the inspection window.Furthermore, because the side ceiling panel is fastened to the second support plate so that its mounting position can be adjusted, when the mounting position of the second support plate relative to the side structure is adjusted, the mounting position of the side ceiling panel relative to the second support plate can be adjusted according to the amount of adjustment.
[0023] (5) In the railway vehicles described in (4), The upper end of the side ceiling panel is characterized by having an elastic engagement portion that clamps and engages a spring-shaped engaging member that is attached to a hanging hardware attached to the roof structure so that the mounting position can be adjusted.
[0024] In the present invention, the upper end of the side ceiling panel is provided with an elastic engagement portion that clamps and engages a spring-like locked member that is attached to a hanging hardware attached to the roof structure so that the attachment position can be adjusted, so that the lower end of the side ceiling panel can be removed from the second support plate while the upper end of the side ceiling panel is attached to the hanging hardware of the roof structure, while absorbing manufacturing errors of the roof structure, etc. Then, by elastically deforming the spring-like locked member that engages with the elastic engagement portion, or by disengaging the elastic engagement portion from the spring-like locked member, the side ceiling panel can be separated from the inspection window formed in the side structure, making it easy to inspect the equipment inside the inspection window.
[0025] (6) A method for manufacturing a railway vehicle according to (1) or (2), a temporary fixing step of temporarily fixing the interior part to the receiving plate via the movable bolt; a temporary fixing process of temporarily fixing the support plate to which the interior part has been temporarily fixed to the body structure via the fixing bolts; and an adjusting step of moving and adjusting the mounting position of the temporarily fixed interior part to a normal position relative to the body structure.
[0026] In the present invention, a temporary fixing process is provided in which the interior part is temporarily fixed to the receiving plate via a movable bolt, and a temporary fixing process is provided in which the receiving plate with the temporarily fixed interior part is temporarily fixed to the body structure via a fixing bolt. Therefore, by temporarily fixing the interior part to the receiving plate in the temporary fixing process, and then temporarily fixing the receiving plate with the temporarily fixed interior part to the body structure in the temporary fixing process, the work of attaching the interior part to the body structure can be carried out quickly.
[0027] Furthermore, since an adjustment step is provided to move and adjust the mounting position of the temporarily fixed interior part to the correct position relative to the body structure, the mounting position of the interior part can be moved and adjusted to the correct position relative to the body structure while the interior part and the support plate are temporarily fixed to the body structure. This eliminates the need for work such as drilling holes and threading to fit the actual vehicle in the body structure, and also eliminates the need to support the interior part using a support jig or the like, allowing the mounting position of the interior part to be moved and adjusted to the correct position relative to the body structure easily and quickly. [Effects of the Invention]
[0028] According to the present invention, it is possible to provide a railway vehicle having an interior accessory mounting structure that can eliminate the need for work such as drilling holes and threading the body structure to fit the actual vehicle, speed up screw fastening work, and easily adjust the mounting position in any direction, including front-to-back, up-down, and left-to-right, of the vehicle, and a method for manufacturing the same.

[0030] Next, a railway vehicle having an interior accessory mounting structure representing one aspect of this embodiment and a manufacturing method thereof will be described in detail with reference to the drawings. Specifically, after the interior accessory mounting structure for the railway vehicle according to this embodiment has been described in detail, a manufacturing method of this railway vehicle according to another embodiment will be described.
[0031] <Mounting structure of interior equipment in this railway vehicle> First, the mounting structure for interior accessories in this railway vehicle will be described with reference to Figs. 1 to 9.

Fig. 9 shows a partial cross-sectional view of part E shown in Fig. 6.
[0032] As shown in Figures 1 to 9, a railway vehicle 10 representing one aspect of this embodiment is a railway vehicle 10 having a mounting structure 3 for an interior fitting 2 that is attached to the inside of the carbody of a body structure 1. Here, the body structure 1 refers to the side body structure 1G, roof body structure 5, etc. that make up the body of the railway vehicle 10. Furthermore, the interior fitting 2 refers to equipment that is attached to the inside of the carbody, such as a luggage rack or a hanging device. The interior fitting 2 is preferably an item that is formed in a long shape and is susceptible to manufacturing errors and assembly errors of the body structure 1.
[0033] 2 to 4, the mounting structure 3 is provided with: a fixing bolt 31 fixed to the body structure 1 and having a male thread portion 31a protruding toward the inside of the car body; a backing plate 32 inserted into the male thread portion 31a of the fixing bolt 31 from the inside of the car body and formed so that its mounting position relative to the fixing bolt 31 can move in a first direction (the direction of arrow P1) along the mounting surface 11 of the body structure 1; and a movable bolt 33 supported by the backing plate 32 so as to be movable in a second direction (the direction of arrow P2) perpendicular to the first direction and along the mounting surface 11 of the body structure 1, and having a male thread portion 33a protruding from the backing plate 32 toward the inside of the car body for attaching the mounting seat 21 of the interior part 2. The interior part 2 is fastened to the backing plate 32 via the movable bolt 33, and the backing plate 32 is fastened to the body structure 1 via the fixing bolt 31.
[0034] Here, the fixing bolts 31 are fixed to a mounting plate 11G arranged inside the vehicle body of a side inner frame 12G, which is a reinforcing frame of the side structure 1G. The heads (base ends) of multiple (for example, four) fixing bolts 31 are embedded and fixed in the mounting plate 11G, and the male thread portion 31a of each fixing bolt 31 protrudes in the direction perpendicular to the mounting surface 11 (in the direction of arrow P3). Note that the mounting plate 11G does not have to be limited to a rectangular dedicated plate formed for fixing the fixing bolts 31, and may be, for example, a door pocket panel arranged adjacent to a side entrance.
[0035] The support plate 32 is composed of a first support plate 32A arranged on the mounting surface 11 side of the body structure 1 and a second support plate 32B arranged on the mounting seat 21 side of the interior part 2. The first support plate 32A and the second support plate 32B have elongated screw insertion holes 324, 325 of the same shape and at the same position, through which the male thread portion 31a of the fixing bolt 31 can be inserted and which can move in the first direction (the direction of arrow P1). In one aspect of this embodiment, the first support plate 32A and the second support plate 32B are separate bodies, but the first support plate 32A and the second support plate 32B may be formed integrally. The mounting seat 21 of the interior part 2 has a plurality (for example, four) of screw insertion holes 211 formed therein, through which the male thread portion 33a of the movable bolt 33 can be inserted.
[0036] With the above configuration, the mounting position of the support plate 32 relative to the fixing bolt 31 fixed to the body structure 1 can be adjusted by moving the support plate 32 in a first direction along the mounting surface 11 of the body structure 1, and the mounting position of the interior part 2 relative to the support plate 32 can be adjusted by moving the movable bolt 33 in a second direction perpendicular to the first direction and along the mounting surface 11 of the body structure 1. Furthermore, by adjusting the thickness of the support plate 32, the mounting position of the interior part 2 relative to the body structure 1 can be adjusted in a third direction (the direction of arrow P3) perpendicular to the first and second directions. Here, the first direction corresponds to the up-down direction of the vehicle, the second direction corresponds to the fore-aft direction of the vehicle, and the third direction corresponds to the left-right direction of the vehicle. Therefore, the mounting position of the interior part 2 relative to the body structure 1 can be easily adjusted in any direction, including fore-aft, up-down, and left-right, of the vehicle.
[0037] Furthermore, since the mounting position of the interior part 2 relative to the body structure 1 can be easily adjusted in any direction, including the front-to-rear, up-down, and left-to-right directions of the vehicle, work such as drilling holes and machining female screws to fit the actual vehicle can be eliminated. Furthermore, the interior part 2 is fastened to the backing plate 32 via the movable bolt 33 whose male thread portion 33a protrudes toward the inside of the car body, and the backing plate 32 is fastened to the body structure 1 via the fixing bolt 31 whose male thread portion 31a protrudes toward the inside of the car body, so that the worker can fasten the interior part 2 to the backing plate 32 while checking the male thread portion 33a of the movable bolt 33 protruding from the backing plate 32 toward the inside of the car body, and can fasten the backing plate 32 to the body structure 1 while checking the male thread portion 31a of the fixing bolt 31 protruding from the body structure 1 toward the inside of the car body. Therefore, the work of fastening the interior part 2 to the backing plate 32 with the screws and the work of fastening the backing plate 32 to the body structure 1 with the screws can each be performed smoothly and quickly.
[0038] Therefore, with the railway vehicle 10 according to this embodiment, it is possible to eliminate work such as drilling holes and threading the body structure 1 to fit the actual vehicle, and it is also possible to speed up the screw fastening work, and it is possible to provide a railway vehicle 10 having an attachment structure 3 for the interior part 2 that allows the attachment position of the interior part 2 relative to the body structure 1 to be easily adjusted in any direction, including front-to-back, up-down, and left-to-right, of the vehicle.
[0039] In addition, in the railway vehicle 10 according to this embodiment, a thickness-adjusting liner 34 is preferably mounted between the mounting surface 11 of the body structure 1 and the mounting seat 21 of the interior equipment 2. Here, the thickness-adjusting liner 34 is formed between the backing plate 32 (second backing plate 32B) and the mounting seats 21, 21B of the interior equipment 2, 2B, and has a predetermined thickness that can absorb manufacturing errors of the body structure 1. The thickness-adjusting liner 34 has a screw insertion hole 341 through which the male thread portion 33a of the movable bolt 33 can be inserted. Note that, as the thickness-adjusting liner 34, a plurality of thickness-adjusting liners 34 with different thicknesses may be prepared, and a suitable one may be selected from them, or a plurality of liners may be combined to achieve a suitable thickness. The thickness-adjusting liner 34 may also be mounted between the mounting surface 11 of the body structure 1 and the backing plate 32 (first backing plate 32A). In this case, the plate thickness adjusting liner 34 is formed with a screw insertion hole having substantially the same size as the first receiving plate 32A and through which the male thread portion 31a of the fixing bolt 31 can be inserted.
[0040] With the above configuration, the mounting position of the interior part 2 relative to the body structure 1 can be more easily adjusted in the direction perpendicular to the mounting surface 11 of the body structure 1 (the direction of arrow P3) by adjusting the plate thickness of the plate thickness adjusting liner 34. Therefore, the mounting position of the interior part 2 relative to the body structure 1 can be more easily adjusted in all directions, including the front-rear, up-down, and left-right directions of the vehicle.
[0041] Furthermore, in the railway vehicle 10 according to this embodiment, the support plate 32 is composed of a first support plate 32A arranged on the mounting surface 11 side of the body structure 1 and a second support plate 32B arranged on the mounting seat 21 side of the interior part 2, and it is preferable that the first support plate 32A is formed with a guide hole 321 that supports the head 33b of the movable bolt 33 so that it cannot rotate and guides it in the second direction (the direction of arrow P2), and the second support plate 32B is formed with a screw insertion hole 322 that passes the male threaded portion 33a of the movable bolt 33 so that it can move in the second direction.
[0042] Here, two rectangular guide holes 321 are formed in the first support plate 32A, extending parallel to each other in a second direction (the direction of arrow P2) at positions spaced apart by the hole pitch in the first direction (the direction of arrow P1) of the screw insertion holes 211 formed in the mounting seat 21 of the interior part 2. The heads 33b of two movable bolts 33 are inserted into the two guide holes 321, respectively, so as to be movable in the second direction. The heads 33b of each movable bolt 33 are formed in a substantially square shape, and the outer edge of the head 33b and the inner edge of the guide hole 321 are formed to be able to slide. Note that the four movable bolts 33 are formed separately because they are easy to forge, but for example, the heads 33b of two movable bolts 33 attached to the same guide hole 321 may be formed integrally. In this case, the distance of the sliding contact portion where the outer edge of head 33b and the inner edge of guide hole 321 are in sliding contact becomes longer, and rotation of the head can be more reliably prevented when movable bolt 33 is screwed.
[0043] With the above configuration, by dividing the receiving plate 32 into a first receiving plate 32A having a guide hole 321 formed therein that supports the head 33b of the movable bolt 33 so that it cannot rotate while guiding it in the second direction, and a second receiving plate 32B having a screw insertion hole 322 formed therein that passes the male threaded portion 33a of the movable bolt 33 so that it can move in the second direction, the support structure for the movable bolt 33 relative to the receiving plate 32 can be more easily formed.
[0044] That is, because the guide hole 321 can be formed to penetrate the first receiving plate 32A and the screw insertion hole 322 can be formed to penetrate the second receiving plate 32B, it is possible to perform two types of hole drilling separately on the first receiving plate 32A and the second receiving plate 32B. This makes it easier to form a support structure for the movable bolt 33 relative to the receiving plate 32. Also, the first receiving plate 32A is formed with the guide hole 321 that guides the head 33b of the movable bolt 33 in the second direction (the direction of arrow P2) while supporting it so that it cannot rotate. Therefore, when the interior part 2 is fastened to the second receiving plate 32B via the movable bolt 33, the guide hole 321 can prevent the movable bolt 33 from rotating without holding the head 33b of the movable bolt 33, and this reduces the effort required for the screw fastening work.
[0045] Furthermore, in the railway vehicle 10 according to this embodiment, the interior equipment 2 is a luggage rack 2B equipped with a luggage rack bracket 22B attached to a mounting plate 11G of the side structure 1G, and it is preferable that the fixing bolt 31 is fixed to the mounting plate 11G and the mounting seat 21B of the luggage rack bracket 22B is fastened to the movable bolt 33.
[0046] In this mounting structure 3B for luggage shelf 2B, the mounting positions of first and second support plates 32A and 32B relative to fixing bolts 31 fixed to mounting plate 11G of side structure 1G can be adjusted by moving first and second support plates 32A and 32B in a first direction (direction of arrow P1) along mounting surface 11 of mounting plate 11G, and the mounting position of luggage shelf bracket 22B relative to first and second support plates 32A and 32B can be adjusted by moving movable bolt 33 in a second direction (direction of arrow P2) perpendicular to the first direction and along mounting surface 11 of mounting plate 11G. In addition, the mounting position of luggage shelf bracket 22B relative to mounting plate 11G can be adjusted in a third direction (direction perpendicular to mounting surface 11 of mounting plate 11G: direction of arrow P3) perpendicular to the first and second directions by adjusting the plate thickness of first and / or second support plate 32A and / or second support plate 32B. Therefore, the mounting position of the luggage rack 2B relative to the side structure 1G can be easily adjusted in any direction of the vehicle, including front-rear, up-down, left-right.
[0047] 2, 3, 6, and 7, the second support plate 32B is preferably formed to expose the bracket main body 22BH extending from the mounting seat 21B of the luggage rack bracket 22B toward the inside of the car body, and to have a lower end 42 of the side ceiling panel 4 formed to be able to shield the mounting seat 21B of the luggage rack bracket 22B and the inspection window 1M formed in the side structure 1G, and is fastened to the second support plate 32B in an adjustable mounting position. The side ceiling panel 4 is formed with a notch 43 along the outer edge of the bracket main body 22BH. The inspection window 1M may be an inspection window for the drive mechanism of the side door or an inspection window for the destination indicator lights, etc.
[0048] 3, a substantially L-shaped mounting bracket 327 that is movable in a second direction (the direction of arrow P2) is attached to the lower end side portion 323 of the second support plate 32B. A female thread portion 327Z that engages with a set screw 329 that fastens the lower end portion 42 of the side ceiling panel 4 from a first direction (the direction of arrow P1) is fixed to the mounting bracket 327. The mounting position of the lower end portion 42 of the side ceiling panel 4 relative to the second support plate 32B is adjusted in a third direction by a first adjusting liner 326 attached between the second support plate 32B and the mounting bracket 327, and is adjusted in the first direction by a second adjusting liner 328 attached between the mounting bracket 327 and the lower end portion 42 of the side ceiling panel 4. Therefore, the mounting position of the lower end portion 42 of the side ceiling panel 4 relative to the support plate 32 can be adjusted in any direction, including front-to-rear, up-down, and left-to-right, of the vehicle.
[0049] As shown in FIG. 5, the mounting bracket 327 includes a cover 327X that accommodates the female thread portion 327Y that engages with the set screw 329 so that the female thread portion 327Y can move in the second direction (the direction of arrow P2) and the third direction (the direction of arrow P3), thereby eliminating the need for the first adjusting liner 326. As shown in FIG. 8, a retaining bracket 329b and a stopper bracket 329c for the set screw 329 are attached to the lower end 42 of the side ceiling panel 4 to prevent the set screw 329 from falling. The mounting bracket 327 has an elongated screw insertion hole 327a formed therein that allows the set screw 330, which is fastened to the second receiving plate 32B, to move in the second direction. However, the screw insertion hole 327a may also be elongated in the first direction. In this case, the second adjusting liner 328 may also be unnecessary.
[0050] With the above configuration, by disengaging the push screw 329 from the female thread portions 327Y, 327Z and removing the lower end portion 42 of the side ceiling panel 4 from the second support plate 32B, it is possible to adjust the mounting position of the luggage rack 2B relative to the side structure 1G in any direction, and by tightening the push screw 329 into the female thread portions 327Y, 327Z and attaching the lower end portion 42 of the side ceiling panel 4 to the second support plate 32B, the mounting seat 21B of the luggage rack bracket 22B is hidden, improving the appearance of the luggage rack 2B to passengers.
[0051] Furthermore, the lower end 42 of the side ceiling panel 4, which is formed so as to be able to cover the inspection window 1M formed in the side structure 1G, is fastened to the second support plate 32B in an adjustable mounting position, so there is no need to provide a separate cover for the inspection window 1M, and the side ceiling panel 4 can also serve as a cover for the inspection window 1M. Furthermore, since the lower end 42 of the side ceiling panel 4 is fastened to the second support plate 32B in an adjustable mounting position, when the mounting position of the second support plate 32B relative to the side structure 1G is adjusted, the mounting position of the side ceiling panel 4 relative to the second support plate 32B can be adjusted in accordance with the amount of adjustment.
[0052] Furthermore, as shown in Figures 6, 7 and 9, in the railway vehicle 10 according to this embodiment, it is preferable that the upper end 41 of the side ceiling panel 4 is provided with an elastic engagement portion 411 that clamps and engages with a spring-like interlocking member 52 that is attached to a hanging bracket 51 attached to the roof structure 5 so that the attachment position can be adjusted.
[0053] Here, hanging fitting 51 has an opening with a substantially U-shaped cross section formed along the second direction, which allows the male thread portion of hanging screw 54 to protrude downward of the vehicle (first direction: direction of arrow P1), and spring-like locked member 52, whose tip end extends in the first direction, is fastened by hanging screw 54 so as to be movable in the second direction. A third adjusting liner 53 is attached between hanging fitting 51 and the base end of spring-like locked member 52. Furthermore, elastic engaging portion 411 has a first engaging plate 411a formed in a V-shape and a second engaging plate 411b formed in a flat plate shape to hold the tip end of spring-like locked member 52.
[0054] With the above configuration, the lower end 42 of the side ceiling panel 4 can be removed from the second support plate 32B while the upper end 41 of the side ceiling panel 4 is attached to the hanging fitting 51 of the roof structure 5 in the correct position, while absorbing manufacturing errors and the like of the roof structure 5. Then, by elastically deforming the spring-like locked member 52 that engages with the elastic engaging portion 411, or by disengaging the elastic engaging portion 411 from the spring-like locked member 52, the side ceiling panel 4 can be separated from the inspection window 1M formed in the side structure 1G, allowing easy inspection of the equipment inside the inspection window 1M.
[0055] <Manufacturing method of this railway vehicle> Next, a manufacturing method for the railway vehicle 10 according to this embodiment will be described with reference to Figures 2, 3, and 10. Figure 10 shows a flowchart of the manufacturing process for the railway vehicle shown in Figure 1.
[0056] As shown in Figures 2, 3 and 10, the manufacturing method of the present railway vehicle 10 includes a temporary fixing process S1 in which an interior item 2 (e.g., a luggage rack 2B) is temporarily fixed to a receiving plate 32 (e.g., a first receiving plate 32A, a second receiving plate 32B) via a movable bolt 33, a temporary fixing process S2 in which the receiving plate 32 to which the interior item 2 has been temporarily fixed is temporarily fixed to a body structure 1 (e.g., a side body structure 1G) via a fixing bolt 31, and an adjustment process S3 in which the mounting position of the temporarily fixed interior item 2 is moved and adjusted to the correct position relative to the body structure 1.
[0057] That is, the method includes a temporary fixing process S1 in which the interior parts 2, 2B are temporarily fixed to the receiving plate 32 (32A, 32B) via the movable bolts 33, and a temporary fixing process S2 in which the receiving plate 32 (32A, 32B) to which the interior parts 2, 2B are temporarily fixed is temporarily fixed to the body structure 1, 1G via the fixing bolts 31. Therefore, by temporarily fixing the interior parts 2, 2B to the receiving plate 32 (32A, 32B) in the temporary fixing process S1, and then temporarily fixing the receiving plate 32 (32A, 32B) to which the interior parts 2, 2B are temporarily fixed to the body structure 1, 1G in the temporary fixing process S2, the installation work of the interior parts 2, 2B to the body structure 1, 1G can be performed quickly.
[0058] Furthermore, since the method includes an adjustment step S3 for moving and adjusting the mounting positions of the temporarily fixed interior parts 2, 2B to their correct positions relative to the body structures 1, 1G, the mounting positions of the interior parts 2, 2B can be moved and adjusted to their correct positions relative to the body structures 1, 1G while the interior parts 2, 2B and the support plates 32 (32A, 32B) are temporarily fixed to the body structures 1, 1G. This eliminates the need for work such as drilling holes and processing female screws to fit the body structures 1, 1G to the actual vehicle, and eliminates the need to support the interior parts 2, 2B using a receiving jig or the like, allowing the mounting positions of the interior parts 2, 2B to be easily and quickly moved and adjusted to their correct positions relative to the body structures 1, 1G.
[0059] Therefore, according to the manufacturing method for a railway vehicle 10 of this other embodiment, it is possible to eliminate work such as drilling holes and processing female screws to fit the body structure 1, 1G to the actual vehicle, and it is also possible to speed up the screw fastening work and provide a manufacturing method for a railway vehicle 10 having mounting structures 3, 3B for interior parts 2, 2B whose mounting positions can be easily adjusted in any direction, such as front to back, up to down, left to right, etc., of the vehicle.
[0060] <Action and effect> According to the railway vehicle 10 according to the present embodiment described above in detail, the mounting structures 3, 3B include: a fixing bolt 31 fixed to the body structure 1 and having a male screw portion 31a protruding toward the inside of the car body; a receiving plate 32 (32A, 32B) inserted into the male screw portion 31a of the fixing bolt 31 from the inside of the car body and formed so that the mounting position relative to the fixing bolt 31 can be moved in a first direction (the direction of arrow P1) along the mounting surface 11 of the body structure 1; and a receiving plate 32 (32A, 32B) supported by the receiving plate 32 (32A, 32B) so as to be movable in a second direction (the direction of arrow P2) perpendicular to the first direction and along the mounting surface 11 of the body structure 1, and having a male screw portion 33a for attaching the mounting seats 21, 21B of the interior parts 2, 2B mounted on the receiving plate 32 (32A, 32B). The interior parts 2, 2B are fastened to the receiving plates 32 (32A, 32B) via the movable bolts 33, and the receiving plates 32 (32A, 32B) are fastened to the body structure 1 via fixing bolts 31. Therefore, the mounting positions of the receiving plates 32 (32A, 32B) relative to the fixing bolts 31 fixed to the body structure 1 can be adjusted by moving the receiving plates 32 (32A, 32B) in a first direction along the mounting surface 11 of the body structure 1, and the mounting positions of the interior parts 2, 2B relative to the receiving plates 32 (32A, 32B) can be adjusted by moving the movable bolts 33 in a second direction perpendicular to the first direction and along the mounting surface 11 of the body structure 1. Furthermore, by adjusting the plate thickness of the receiving plate 32 (32A, 32B), the attachment positions of the interior parts 2, 2B relative to the body structure 1 can be adjusted in a third direction (the direction perpendicular to the surface of the attachment surface 11: the direction of arrow P3) that is perpendicular to the first and second directions. Therefore, the attachment positions of the interior parts 2, 2B relative to the body structure 1 can be easily adjusted in any direction, including the front-rear, up-down, left-right, and right-left of the vehicle.
[0061] Furthermore, since the mounting positions of the interior fittings 2, 2B relative to the body structure 1 can be easily adjusted in any direction, including the front-to-rear, up-down, and left-to-right directions of the vehicle, work such as drilling holes and machining female screws to fit the actual vehicle to the body structure 1 can be eliminated. Furthermore, the interior fittings 2, 2B are fastened to the backing plates 32 (32A, 32B) via movable bolts 33 whose male thread portions 33a protrude toward the inside of the car body, and the backing plates 32 (32A, 32B) are fastened to the body structure 1 via fixing bolts 31 whose male thread portions 31a protrude toward the inside of the car body, so that the worker can fasten the interior fittings 2, 2B to the backing plates 32 (32A, 32B) while checking the male thread portions 33a of the movable bolts 33 that protrude from the backing plates 32 (32A, 32B) toward the inside of the car body, and can fasten the backing plates 32 (32A, 32B) to the body structure 1 while checking the male thread portions 31a of the fixing bolts 31 that protrude from the body structure 1 toward the inside of the car body. Therefore, the screw fastening operation of the interior parts 2, 2B to the backing plates 32 (32A, 32B) and the screw fastening operation of the backing plates 32 (32A, 32B) to the body structure 1 can be performed smoothly and quickly.
[0062] Therefore, according to this embodiment, it is possible to eliminate work such as drilling holes and machining female screws to fit the actual vehicle body structure 1, and it is possible to speed up the screw fastening work, and it is possible to provide a railway vehicle 10 having mounting structures 3, 3B for interior parts 2, 2B whose mounting positions relative to the body structure 1 can be easily adjusted in any direction, such as front-to-back, up-down, and left-to-right, of the vehicle.
[0063] Furthermore, according to this embodiment, since the thickness-adjusting liner 34 is attached between the mounting surface 11 of the body structure 1 and the mounting seats 21, 21B of the interior parts 2, 2B, the mounting positions of the interior parts 2, 2B relative to the body structure 1 can be more easily adjusted in the direction perpendicular to the mounting surface 11 of the body structure 1 (the direction of arrow P3) by adjusting the thickness of the thickness-adjusting liner 34. Therefore, the mounting positions of the interior parts 2, 2B relative to the body structure 1 can be more easily adjusted in all directions, including the front-rear, up-down, and left-right directions of the vehicle.
[0064] Furthermore, according to this embodiment, the receiving plate 32 is composed of a first receiving plate 32A arranged on the mounting surface 11 side of the body structure 1 and a second receiving plate 32B arranged on the mounting seats 21, 21B side of the interior parts 2, 2B, and the first receiving plate 32A is formed with a guide hole 321 that guides the head 33b of the movable bolt 33 in the second direction (the direction of the arrow P2) while supporting it so that it cannot rotate, and the second receiving plate 32B is formed with a guide hole 321 that guides the male screw portion 33a of the movable bolt 33 in the second direction (the direction of the arrow P2) while supporting it so that it cannot rotate. By dividing the receiving plate 32 into a first receiving plate 32A having a guide hole 321 formed therein that supports the head 33b of the movable bolt 33 so that it cannot rotate and guides it in the second direction, and a second receiving plate 32B having a screw insertion hole 322 formed therein that passes through the male threaded portion 33a of the movable bolt 33 so that it can move in the second direction, the support structure for the movable bolt 33 relative to the receiving plate 32 can be more easily formed.
[0065] That is, because guide hole 321 can be formed to penetrate first support plate 32A and screw insertion hole 322 can be formed to penetrate second support plate 32B, two types of hole drilling can be performed separately on first support plate 32A and second support plate 32B. This makes it easier to form a support structure for movable bolt 33 relative to support plate 32. Also, because first support plate 32A is formed with guide hole 321 that guides head 33b of movable bolt 33 in the second direction (the direction of arrow P2) while supporting it so that it cannot rotate, when fastening interior part 2, 2B to second support plate 32B via movable bolt 33, guide hole 321 can prevent movable bolt 33 from rotating, reducing the effort required for the screw fastening work.
[0066] Furthermore, according to this embodiment, the interior equipment 2 is a luggage rack 2B equipped with a luggage rack bracket 22B attached to a mounting plate 11G fixed to the inside of the car body of a side inner frame 12G of the side body structure 1G, and the fixing bolt 31 is fixed to the mounting plate 11G and the mounting seat 21B of the luggage rack bracket 22B is fastened to the movable bolt 33, so that the mounting positions of the first and second receiving plates 32A and 32B relative to the fixing bolt 31 fixed to the mounting plate 11G of the side body structure 1G can be adjusted by moving the first and second receiving plates 32A and 32B in a first direction (direction of arrow P1) along the mounting surface 11 of the mounting plate 11G, and the mounting position of the luggage rack bracket 22B relative to the first and second receiving plates 32A and 32B can be adjusted by moving the movable bolt 33 in a second direction (direction of arrow P2) perpendicular to the first direction and along the mounting surface 11 of the mounting plate 11G. Furthermore, the mounting position of luggage shelf bracket 22B relative to mounting plate 11G can be adjusted in a third direction (direction perpendicular to mounting surface 11 of mounting plate 11G: direction of arrow P3) that is perpendicular to the first and second directions by adjusting the plate thickness of first support plate 32A and / or second support plate 32B. Therefore, the mounting position of luggage shelf 2B relative to side structure 1G can be easily adjusted in any direction, including front-to-rear, up-down, and left-to-right, of the vehicle.
[0067] In addition, the second support plate 32B is formed so that the bracket main body 22BH, which extends from the mounting seat 21B of the luggage shelf bracket 22B toward the inside of the car body, can be exposed, and the lower end portion 42 of the side ceiling panel 4, which is formed so that it can shield the mounting seat 21B of the luggage shelf bracket 22B and the inspection window 1M formed in the side structure 1G, is fastened to it so that the mounting position can be adjusted.Therefore, by removing the lower end portion 42 of the side ceiling panel 4 from the second support plate 32B, it is possible to adjust the mounting position of the luggage shelf 2B relative to the side structure 1G, and by attaching the lower end portion 42 of the side ceiling panel 4 to the second support plate 32B, the mounting seat 21B of the luggage shelf bracket 22B can be hidden, improving the appearance of the luggage shelf 2B to passengers.
[0068] Furthermore, the lower end 42 of the side ceiling panel 4, which is formed so as to be able to cover the inspection window 1M formed in the side structure 1G, is fastened to the second support plate 32B in an adjustable mounting position, so there is no need to provide a separate cover for the inspection window 1M, and the side ceiling panel 4 can also serve as a cover for the inspection window 1M. Furthermore, since the side ceiling panel 4 is fastened to the second support plate 32B in an adjustable mounting position, when the mounting position of the second support plate 32B relative to the side structure 1G is adjusted, the mounting position of the side ceiling panel 4 relative to the second support plate 32B can be adjusted in accordance with the amount of adjustment.
[0069] Furthermore, according to this embodiment, the upper end 41 of the side ceiling panel 4 is provided with elastic engagement portions 411 that sandwich and engage spring-like locked members 52 that are attached to hanging fittings 51 attached to the roof structure 5 in an adjustable manner, so that the lower end 42 of the side ceiling panel 4 can be removed from the second support plate 32B while the upper end 41 of the side ceiling panel 4 is attached to the hanging fittings 51 of the roof structure 5, while absorbing manufacturing errors, etc. of the roof structure 5. Then, by elastically deforming the spring-like locked members 52 that engage with the elastic engagement portions 411, or by disengaging the elastic engagement portions 411 from the spring-like locked members 52, the side ceiling panel 4 can be separated from the inspection window 1M formed in the side structure 1G, allowing easy inspection of the equipment inside the inspection window 1M.
[0070] Furthermore, according to the manufacturing method for a railway vehicle of this other embodiment, there are provided a temporary fixing process S1 in which the interior parts 2, 2B are temporarily fixed to the receiving plate 32 (32A, 32B) via the movable bolts 33, and a temporary fixing process S2 in which the receiving plate 32 (32A, 32B) to which the interior parts 2, 2B are temporarily fixed is temporarily fixed to the body structure 1, 1G via the fixing bolts 31. Therefore, by temporarily fixing the interior parts 2, 2B to the receiving plate 32 (32A, 32B) in the temporary fixing process S1, and then temporarily fixing the receiving plate 32 (32A, 32B) to which the interior parts 2, 2B are temporarily fixed to the body structure 1, 1G in the temporary fixing process S2, the work of attaching the interior part 2 to the body structure 1, 1G can be performed quickly.
[0071] Furthermore, since the method includes an adjustment step S3 for moving and adjusting the mounting positions of the temporarily fixed interior parts 2, 2B to their correct positions relative to the body structures 1, 1G, the mounting positions of the interior parts 2, 2B can be moved and adjusted to their correct positions relative to the body structures 1, 1G while the interior parts 2, 2B and the support plates 32 (32A, 32B) are temporarily fixed to the body structures 1, 1G. This eliminates the need for work such as drilling holes and processing female screws to fit the body structures 1, 1G to the actual vehicle, and eliminates the need to support the interior parts 2, 2B using a receiving jig or the like, allowing the mounting positions of the interior parts 2, 2B to be easily and quickly moved and adjusted to their correct positions relative to the body structures 1, 1G.
[0072] <Modification> While the railway vehicle 10 and its manufacturing method according to this embodiment have been described in detail above, the present invention is not limited thereto and various modifications are possible without departing from the spirit of the present invention. For example, in this embodiment, the interior part 2 is a luggage rack 2B having a luggage rack bracket 22B attached to an attachment plate 11G fixed to the inside of the carbody of a side inner frame 12G of a side body structure 1G, and the fixing bolt 31 is fixed to the attachment plate 11G, and the mounting seat 21B of the luggage rack bracket 22B is fastened to the movable bolt 33. However, this is not necessarily limited thereto. For example, the interior part 2 may be a hoisting tool having a hoisting tool bracket attached to an attachment plate fixed to the inside of the carbody of the roof body structure 5, and the fixing bolt 31 may be fixed to the attachment plate, and the mounting seat of the hoisting tool bracket may be fastened to the movable bolt.
