[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting device and a method for mounting a housing of a switching device such as a turning machine or a crank for performing a shift locking of a turnout in a railway. Things.

[0002]

2. Description of the Related Art Conventionally, in a railroad, a branch for moving a railcar from one track (hereinafter referred to as "main line") to another track (hereinafter referred to as "branch line") is performed. Vessel is used. This switch is generally
It has a configuration as shown in FIG. The branching device 100 shown in FIG. 5 includes basic rails R1 and R2, tong rails T1 and T2 to the branch line side, an electric switch 101, and a transmission unit.

[0003] The tongue rails T1, T2, which are in close contact with the basic rails R1, R2, are formed with a tongue-like tip. Further, the transmission unit 108 includes the operation can 102 and the link member 1.
03a, 103b, 103c, 103d, 103e and 103f, escape cranks 104 and 106,
Switch adjusters 105 and 107, and pole 10
9, 110. Switch adjuster 1
05 and 107 are attached to the tong rails T1 and T2 via the poles 109 and 110, respectively.

[0004] The electric pointing machine 101 has a conversion mechanism (not shown) in which an electric motor (not shown) is used as a driving force, and the rotational driving force of the electric motor is linear. The driving force is converted into a driving force, and the operating rod 102 is driven in the rightward or leftward direction in FIG. The movement of the operation can 102 is controlled by the transmission adjuster 108 by the switch adjusters 105 and 1.
07, the tong rails T1, T2 are moved via the poles 109, 110.

[0005] For example, when the operation can 102 moves rightward in FIG.
5, 107 move downward, for example, in FIG. 5, so that the tip of the tongue rail T2 (left end in FIG. 5) is in close contact with the basic rail R2, and the tip of the tongue rail T1 (left end in FIG. 5) is the basic rail. Move away from R1. When the operation can 102 moves leftward in FIG. 5, the switch adjusters 105 and 107 move upward, for example, in FIG.
2 is separated from the main rail R2, and the tongue rail T1 is in close contact with the basic rail R1.

[0006] By the above operation, the branching device 100
Can perform a tongue rail conversion operation for switching the course to the main line side or the branch line side. In this case, one of the positions where the tongue rail is in close contact with the main line side rail,
For example, a position where the tip of the tongue rail T1 is separated from the basic rail R1 and the tip of the tongue rail T2 is in close contact with the basic rail R2 is called "localization", and the other position, for example, the tip of the tongue rail T1 is in close contact with the basic rail R1. Rail T
The position at which the tip of No. 2 is separated from the basic rail R2 is called "inversion". These are arrangements in train operation, and the opposite positions may be determined as localization or inversion.

[0007] The point machines and cranks for performing the above-mentioned conversion locking of the switch are mounted by the mounting method shown in FIG. FIG. 6 is a diagram showing a configuration of an escape crank in a conventional branching device. FIG. 6 (A) shows a top view, and FIG. 6 (B) shows a side view. As shown in FIG. 6, the escape crank 104
As shown in FIG. 6, the floor plate 122 is placed on the sleepers 121 and 122, and the bolt mounting holes 14 of the housing 104a are mounted.
1, a bolt mounting hole is formed in the bottom plate 122 and the sleeper 122, and the mounting bolt 123 'is inserted through the washer 125'.
And the nut 104 ′ and the like, the casing 104 b is attached to the sleeper 122 via the bottom plate 126.

[0008] However, it is very difficult to install the sleeper of the turnout while positioning it in accordance with the dimensions of the design drawing at the time of construction. For this reason, a bolt mounting hole for mounting a turning machine or a crank to a sleeper or the like cannot be accurately opened in advance in the sleeper or the like. Conventionally, therefore, it is necessary to lay a floor plate on the sleeper where the body is to be mounted, temporarily place the point machine and cranks, determine the position of the bolt mounting hole, and make a bolt mounting hole in the floor plate and the sleeper. I had to. In addition, in order to open at least four or more bolt mounting holes in a sleeper or the like and allow the mounting bolts to pass through all the bolt mounting holes, the diameter of the bolt mounting holes must have a sufficient margin with respect to the diameter of the mounting bolt. I needed to have it.

[0009]

However, even if the body such as the mounting bolt and the nut is sufficiently fastened, if the body receives a large force from the lateral direction (horizontal direction), the body is slept. The force to be maintained (horizontal component) depends on the coefficient of friction between the case body and the floor plate, etc., and thus is greatly reduced to several tenths of the tightening force of the mounting bolt.

Further, the diameter of the bolt mounting hole is set to a value having a sufficient margin with respect to the diameter of the mounting bolt (the diameter of the bolt mounting hole is a value obtained by adding a margin value to the diameter of the mounting bolt. Therefore, the mounting bolt can be slightly moved. Due to this, for example, if the body receives a lateral force, the cranks will rotate slightly,
There was a case where the position of the electric point slightly shifted. If such a minute rotation or misalignment occurs, the nut of the mounting bolt is loosened, the adhesion of the tongue rail of the branching device is deteriorated, and the tip of the tongue rail is misaligned, so that the electric pointing machine is out of lock. And other problems have occurred.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a mounting device and a method for a mounting device which is less likely to be displaced. It is in.

11b and the adjustment fittings 12, 12 'or 22, 22',
Alternatively, since they are pressed without gaps by 32 and 32 ', minute movement and minute rotation are prevented.

Further, unlike the conventional example, it is not necessary to form at least four bolt mounting holes. The fitting procedure is as follows. After fitting the casing 104a to the side of the fixtures 11a and 11b, the adjusting fittings 12, 12 'or 22, 22', or 32, 32 'are moved in the direction along the side surface of the casing 104a. By sliding, the wedge action causes the casing 104a to be pressed against the fixing bracket without any gap.

Also, the adjustment fittings 12, 12 'or 22,
If the 22 'or 32, 32' is tightened with the bolt 14, the upper slope of the housing 104a can be pressed down, so that the housing 104a can be prevented from rising upward. That is, by tightening one bolt 14, both the side surface S1 and the upper slope S2 of the casing 104a can be pressed, so that work efficiency is improved.

Further, the back of the first adjustment fitting 42, 42 'or 52, 52' or 62, 62 'is connected to the second adjustment fitting 44, 44' or 54, 54 'or 64, 64'.
If the bolts of the first adjustment fitting or the second adjustment fitting are damaged or loosened, the fixed state of the casing 104a can be maintained.

In the above embodiment, the switches and cranks for performing the locking of the switch are equivalent to the switch.

The present invention is not limited to the above embodiment. The above embodiment is an exemplification, and has substantially the same configuration as the technical idea described in the scope of the claims of the present invention. It is included in the technical scope of the invention.

As described above, according to the present invention,
Since it is not necessary to drill mounting holes so that the mounting holes of at least four or more bodies match each other as in the conventional example, the position of the mounting holes can be accurately scribed, and the time required for drilling the mounting holes can be shortened. There is no mistake in opening position. Since the housing is sandwiched between the fixing bracket and the adjusting bracket and further pressed down by the adjusting bracket, it can be fixed without a gap with a much stronger force than the conventional bolting method. The adjustment bracket is
Since the wedge is driven into the fixing portion between the housing and the fixing body, even if the bolt is loosened, the adjusting bracket does not easily move in the direction in which the adjusting bracket comes off. Therefore, the case can be securely fixed in a short time, and even if the bolts are loosened, the fixing state of the case is hardly affected.
