Description

[0001]
BACKGROUND OF THE INVENTION
Among linear motor cars, there are an on-vehicle primary system in which the primary coil of the linear motor is on the vehicle side, and a ground primary system on the ground side. Among the former on-vehicle primary systems, there are a type that travels while being supported by wheels and a type that travels while magnetically levitating. The present invention relates to a method for mounting a reaction plate on a rail in which a reaction plate constituting a secondary side conductor of the linear motor is mounted on the rail in a linear motor car on a vehicle that travels while magnetically levitating. .
[0002]
[Prior art]
Conventionally, in an on-vehicle primary type linear motor car that travels while magnetically levitating, as shown in FIG. 15, for example, engaging grooves 1a and 1b are formed under the shoulder of the rail 1, while both sides of the reaction plate 2 are formed. The side portions 2a and 2b are provided to slightly open outward and protrude downward. Then, as shown in the figure, the reaction plate 2 is placed on the rail 1 via the rust preventive sheet 3, and the reaction plate 2 is caulked by applying pressure in the direction of the arrow as shown in FIG. The reaction plate 2 was mounted on the rail 1 by engaging with.
[0003]
[Problems to be solved by the invention]
However, in such a reaction plate mounting method, since the engaging grooves 1a and 1b must be formed in the rail 1, machining or the like is required after roll forming, and the manufacturing cost is high, and a length of 10 m is also required. Machining, etc. to a certain rail 1 can only be performed at a factory equipped with special equipment, so sometimes it will be produced at a remote location and transported to the site, which may increase the cost of transportation after production. There was a problem.
[0004]
In addition, since the reaction plate 2 must be caulked on the rail 1, a dedicated caulking jig must be prepared in order to increase the efficiency of the caulking work. Since the work cannot be performed unless there is a caulking jig, there is a problem that the transportation cost after the production may increase.
[0005]
Therefore, the object of the present invention is to make it possible to attach a reaction plate on a rail for a linear motor car without the need for machining to the rail or a dedicated caulking jig, thereby reducing the production cost and special equipment. It is also possible to attach a reaction plate on a rail for a linear motor car so that the work can be performed even in a factory that does not have a dedicated caulking jig, thereby reducing the transportation cost.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 13 shows a linear motor car on a track provided on an elevated road. Reference numeral 15 in the figure is a leg that stands on a road 17 on which a car 16 or the like travels. The legs 15 are provided at intervals in the traveling direction of the linear motor car 18 that is orthogonal to the paper surface along the road 17. A PC concrete track girder 19 is bridged over the legs 15. That is, the track girder 19 extends in the traveling direction of the linear motor car 18.
[0010]
On the track girder 19, as shown in FIGS. 11 and 12, a pair of pedestals 20 are placed on the left and right in the width direction of the track girder 19. The pedestals 20 are made of a non-shrink mortar and have a rectangular parallelepiped shape, are both installed parallel to each other in the direction of the track girder, and are provided at regular intervals in the direction of the track girder. On the pedestal 20, a steel-made rectangular plate-like base plate 22 is installed via an adjustment pad 21 made of mortar, iron plate, rubber or the like. The preparation pad 21 and the base plate 22 are just sized to be placed on the pedestal 20, for example, a width of 200 mm, a length of 400 mm, and a thickness of about 19 mm. Then, the base plate 22 is pressed through an washer 25 with an anchor bolt 24 that passes through the base plate and is screwed into an anchor nut 23, and holds the adjustment pad 21 to be fixed on the base 20. The anchor nut 23 is embedded in the track girder 19 and the base 20.
[0011]
On the pair of base plates 22 and 22 on the left and right in the width direction of the track girder 19, a sleeper 26 made of an H-shaped steel material is stretched, and the web portion 26 c is erected and the flange portions 26 a and 26 b are placed on the upper and lower sides to fix the bolt 27 to fix. On the sleepers 26, rails 28 are provided over the sleepers 26.
[0012]
The rail 28 is made of rolled steel, and is composed of a main body portion 28a having an inverted U-shaped longitudinal section and a flat plate portion 28b protruding from one shoulder portion thereof, and a secondary side conductor of the linear motor 39 is provided on the main body portion 28a. A plurality of aluminum reaction plates 29 are sequentially covered as shown in FIG. 12, and the flat plate portion 28b is placed on the upper flange portion 26a of the sleeper 26 with the thin steel shim plate 30 as shown in FIG. 31 and a nut 32 are fixed. As a result, the rail 28 was laid on the track girder 19.
[0013]
By the way, below the rail 28, as shown in FIG. 10, an electromagnet 35 having a U-shaped longitudinal section is provided so as to face the rail. The electromagnet 35 is provided in a module 38 by connecting the coil 36 to a controller 37. The module 38 corresponds to a bogie of a railway vehicle, and is provided with four electromagnets 35, one linear motor 39, a brake device (not shown), etc., on a casing 38a having a vertical cross section "". The secondary coil 39a of the linear motor 39 is provided above the rail 28 so as to face the reaction plate 29, and six are attached to the bottom of the vehicle body main body 41 of the linear motor car 18 via the air spring 40. .
[0014]
Then, the rail 28 is attracted from below by the electromagnet 35, detected by a sensor (not shown) and kept constant between the electromagnet 35 and the rail 28, the vehicle body 41 is levitated to a predetermined height, and the secondary coil 39a is energized. Then, the reaction plate 29 is repelled by suction and travels through the linear motor car 18. At this time, the main body 28a having the inverted U-shaped longitudinal section of the rail 28 and the electromagnet 35 having the U-shaped longitudinal section are opposed to each other, so that a force acts in a direction to restore the electromagnet 35 when it is shifted to the left and right. In this way, the left and right shift of the linear motor car 18 is prevented.
[0015]
In the first aspect of the present invention, as shown in FIG. 2, first, pin holes 28c and 28d are formed in the shoulder portion of the main body portion 28a of the rail 28 inwardly from both sides at intervals in the length direction. I can make it. As shown in FIG. 3, a plurality of reaction plates 29 are placed on the main body 28a. One reaction plate 29 protrudes downward on both sides to be provided with side portions 29a and 29b, and linear grooves 29c and 29d extending in the length direction are formed on the outer surfaces of the side portions 29a and 29b. The straight grooves 29c and 29d are formed so that the entrance is small and the depth is large, for example, as illustrated.
[0016]
Then, as shown in FIG. 4, a plurality of side through holes 29e penetrating the side portions 29a are formed at the bottom of the linear groove 29c at intervals in the length direction. Similarly, when a plurality of side through holes are formed and the reaction plate 29 is put on the rail 28, the side through holes 29e are aligned with the pin holes 28c and 28d of the rail 28, respectively. Then, as shown in FIG. 5, the attachment pins 45 and 46 are inserted into the side through holes 29 e and the tips are inserted into the pin holes 28 c and 28 d, and the reaction plate 29 is attached to the rail 28.
[0017]
In the illustrated embodiment, the pin holes 28 c and 28 d are formed in a slightly elongated hole in the length direction of the rail 28, and the side through hole 29 e is also formed in a slightly elongated hole in the length direction of the reaction plate 29. Even if a difference in expansion and contraction occurs between the rail 28 and the reaction plate 29 due to the temperature change, they can move relative to each other.
[0018]
Thereafter, aluminum retaining rods 47, 48, for example, are inserted into the straight grooves 29c, 29d, and the mounting pins 45, 46 are retained by the retaining rods 47, 48 as shown in FIG. The shape of the retaining rods 47 and 48 is not particularly limited. In the illustrated embodiment, the retaining rods 47 and 48 are formed in a laterally convex shape so as not to cause backlash after insertion. Then, the linear grooves 29c and 29d are closed to prevent water and the like from entering between the rail 28 and the reaction plate 29 through the side through holes 29e, thereby preventing corrosion and reinforcing the cross sections of the side portions 29a and 29b. I also do.
[0019]
By the way, in the invention described in claim 2, as shown in FIG. 7, for example, one retaining hole 47a is opened in the retaining collar 47, and the reaction plate 29 has a second position at a position corresponding to the collar through hole 47a. The side through hole 29f is opened, a spring pin 49 is inserted as a holding pin in the collar through hole 47a, the tip is inserted into the second side through hole 29f, and the retaining collar 47 is retained. Although not shown, the other retaining rod 48 is similarly retained by a holding pin.
[0020]
Thereafter, as shown in FIG. 8, a rust-proof putty 50 is applied so as to close the gap between the straight groove 29c and the retaining rod 47, and although not shown, the gap between the rod through hole 47a and the spring pin 49 is blocked. The antirust putty 50 is applied as described above. Similarly, although not shown, a rust-proof putty is applied in a similar manner so as to close the gap between the other straight groove 29d and the retaining rod 48, and the gap between the other flange through hole 48a and the spring pin 49 is blocked. Rust putty 50 is applied. This makes it difficult for moisture to enter between the rail 28 and the reaction plate 29. And finally, as shown in FIG.
[0021]
FIG. 9 is a perspective view for explaining a specific working method for fixing the reaction plate 29 on the rail 28. For example, as shown in FIG. 9, after placing the reaction plate 29 on the rail 28, as shown by the arrows in the figure, first, four attachment pins 45 and 46 are respectively attached to the one reaction plate 29 from both sides. The tip is inserted into the through hole 29e and inserted into the pin holes 28c and 28d. Thereafter, the wires 53 and 54 drawn out from the winches 51 and 52 are respectively passed through the linear grooves 29c and 29d, and hooks at their tips are hooked into small holes formed at one ends of the retaining rods 47 and 48, respectively. The wires 53 and 54 are wound up and the retaining rods 47 and 48 are inserted into the straight grooves 29c and 29d. Then, after removing the wires 53 and 54 from the retaining rods 47 and 48, as shown by the arrows in the figure, one spring pin 49 is inserted into each of the reaction plate 29 from both sides into the rod through-hole 47a, and the tip Is inserted into the second side through hole 29f.
[0022]
In the illustrated embodiment described above, the retaining rods 47 and 48 are inserted into the linear grooves 29c and 29d of the plurality of reaction plates 29 at once using the winches 51 and 52, but of course, they may be inserted by hand. .
[0023]
In the third aspect of the present invention, when the reaction plate 29 is mounted on the rail 28, it is covered with an asphalt sheet 55 as a rust preventive sheet as shown in FIGS. Thereby, electrolytic corrosion due to a foreign metal between the rail 28 and the reaction plate 29 is prevented.
[0024]
