Description

[Detailed description of the invention] 3-1 Field of industrial application This invention connects the bottom plate on which the electric iron machine is placed and fixed, and the clamp that can clamp the basic rail near the bottom plate, using a connecting rod. The middle part of the connecting rod is cylindrical, with male threads carved on only both ends, and the root diameter of the male screw on the clamping side is larger than the outer diameter of the male screw on the bottom plate side, simplifying the structure of the connecting rod itself. In addition to making it possible to replace the connecting rod, which was considered impossible in the past, this technology also makes it possible to speed up and simplify the installation work of electric point machines. This invention relates to a switch machine installation device that has safer and more reliable functions and can reduce maintenance and inspection efforts.

3-2 Prior Art As an example of conventional means for installing an electric switch machine on the basic rail, as shown in Figs. In Figure 3, the lower part is the front and the upper part is the rear), respectively. 8, and the through holes 11', 12' of the clamps 11, 12 on which the bottoms of the left and right basic rails 9, 10 are placed, respectively.
, the male screw 5″ carved on the left end of the connecting rods 5 and 6,
6" and the left ends of the male screws 5', 6', and tighten the male screws 5', 5", 6 by tightening nuts 15.16 through curved washers 13, 14 that abut on the outside of these clamps 11, 12, respectively. ', 6'' are tightened to hold the basic rails 9, 10 in fixed positions. Also, a locking rod 17 and an operating rod 18, which extend leftward from the rear left end of the electric point machine 1, respectively. The front rod 19 and the switch adjuster 20 are attached to the left end, and the U-shaped armrest 21 attached to the front rod 19,
At the same time, the front ends of the tip rails 23 and 24 are fixed to the tips of the tip rails 22, and a rolling rod 25 is attached to the switch adjuster 20, so that the adhesion force of the tip rails 23 or 24 to the basic rails 9 or 10 is always constant. It can be adjusted to suit.

3-3 Problems to be solved by the present invention Under the above configuration, the basic rails 9, 10 of the wheels when a train (not shown) passes
Although the basic rails 9, 10 move due to the lateral pressure on the side of the head, the gauge cages of the basic rails 9, 10 connected by the connecting rods 5, 6 are always constant, The bottom plate 2 connected to the base plate 2 via the screw joints 3 and 4 also follows and is displaced, but since the installation position relative to the basic rails 9 and 10 is constant, the amount of displacement on the left and right of the tip rails 9 and 10 is also It will be held constant. However, due to repeated passing of the train through the switch section, the basic rails 9 and 1
As a result of the cumulative slight movement of the connecting rods 5 and 6, the male screws 5' and 6' are gradually worn and damaged, and the male screws 5'' and 6'' on the basic rails 9 and 10 side are Since the vibrations and shocks caused by passing trains are directly applied, the degree of wear and damage to the male screws 5' and 6' on the electric point machine 1 side is more serious than that of the male screws 5' and 6', so It is necessary to perform inspection and adjustment, and since the outer diameters of the male screws 5', 6' and 5'', 6'' in these connecting rods 5, 6 are all the same, the male screws 5'', 5'' on the basic rails 9, 10 side
It is clear that the degree of wear and damage on the electric point machine 6'' is greater than that on the electric point machine 1 side.In addition, during track consolidation work, the connecting rod 5,
There is a risk that the screw threads of the connecting rods 5 and 6 may be crushed or deformed due to contact with the connecting rods 5 and 6, and there is also the possibility that the material may deteriorate due to falling dirt, sewage, etc. from passing trains, or due to natural environments such as snowfall and rainwater. In an unfavorable situation such as the occurrence of rust, the nut fitted to the male threads of the connecting rods 5 and 6 becomes one rigid body by integrating with the male threads, so the nut cannot be loosened even with a tool such as a spanner or screwdriver. Therefore, it is virtually impossible to replace the connecting rods 5 and 6. Therefore, the connecting rods 5 and 6 were removed by cutting with a knife or due to fire, etc., so that all materials were completely lost. It is wasteful and uneconomical, and furthermore, when installing the connecting rods 5 and 6, when tightening the nuts 15 to the male screws 5'' and 6'' on the basic rail 10 side, the nuts 15 must be fastened to the bottom plate 2.
Since it is necessary to move by rotation along the male screws 5' and 6' one by one from the side, it is difficult to avoid a great deal of wasted time and a sense of complication, and there is no hope of improving work efficiency. Basic rail 1 near the bottom plate
Male thread 5' of connecting rods 5 and 6 between 0 and
6′ has no direct effect on the transfer function, and
It takes unnecessary effort and time to carve the male screws 5', 6', and this is one of the reasons for the rise in the price of the connecting rods 5, 6 themselves.

This idea was proposed by focusing on the above-mentioned drawbacks, and its objectives were to speed up and simplify the installation work of electric point machines, simplify the structure of the connecting rod itself, and improve its strength. In conjunction with this, the present invention aims to provide a switch machine installation device that can be expected to reduce labor during maintenance and inspection.

3-4 Means for Solving the Problems In order to achieve the above-mentioned purpose, the electric switch machine installation device according to this invention includes a bottom plate for mounting and fixing the electric switch machine, a clamp, and a bottom plate. This is an electric point machine installation device consisting of a pair of connecting rods placed one behind the other. The root diameter is larger than the outer diameter of the male screw on one end, and one end is connected to the bottom plate, and the other end is connected to the basic rail near the bottom plate with a clamp.

3-5 Example Hereinafter, referring to FIGS. 1 and 2, an example of this invention will be described.
Protruding pieces e, e are formed at appropriate locations on the front and rear of 1 (the lower part is the front and the upper part is the rear in Fig. 1), and adjustment holes e', e' are formed in these protruding pieces e, e, respectively. A claw bolt 33 is passed through the sleeper 32 below the sleeper 32, and is tightened with a tightening nut 34 through the insulating collar i and collar C, and the floor plate 31 is adjustably attached to the sleeper 32, while the electric point machine Z is installed. It is firmly placed and fixed on the bottom plate 31 via the point machine fixing fittings y, and the bottom plate 3
Female threads a ₁ and a ₂ are carved into the joint pieces j _{1 and j 2 that} can be fixed and suspended from the lower surface of the connecting rod ₃₅ ( Hereinafter, the front and rear members such as the connecting rod and the clamps, washers, nuts, etc. attached thereto are the same, so for convenience,
Let's talk about the husband at the back. ) is engraved only on the end (in this case, the right end), so that the left joint piece j ₁
Male thread S ₁ through spring washer W ₁ to nut N ₁ on the left side of
The basic rail R ₂ side end of the cylindrical intermediate part m that is screwed and tightened, is formed with a root diameter d ₂ that is slightly larger than the outer diameter d ₁ of this male thread S ₁ , and has no male thread carved therein. A male screw S ₂ is carved only in the hole, and the carved part of the male screw S ₂ is passed through the through holes b and h of a pair of clamps 37 and 38 on which the bottom of the basic rail R ₂ is placed. A flat washer W ₂ , a nut n 2 , a spring washer u ₂ and a nut _{g 2 are} arranged in parallel toward the outside of the clamps 37 and 38, respectively.
The male screw S ₂ is tightened to hold the basic rail R ₂ in a fixed position, and the bottoms of the clamps 37 and 38 are brought into contact with each other through the uneven portion to prevent the clamps 37 and 38 from swinging themselves. It has been done. Thus, a flat portion f ₁ is formed at the tip of the columnar portion P on the left side of the basic rail R ₂ of the connecting rod 35, and the flat portion f ₂ is opposed to the left end of the flat portion f ₁ with a small gap k interposed therebetween. An insulating plate 39 that can bring these pair of flat parts f ₁ and f ₂ into contact with the upper and lower parts, respectively;
39, the connecting plates 40, 40 are superimposed, and these members are fastened and integrated vertically with fasteners 41 such as bolts and nuts, while the extension part on the left side of the flat part _f2 is The basic rail _R1 is clamped and fastened using the same clamps, washers, and nuts as those for the basic rail _R2 . The front connecting rod 35 is made to protrude slightly from the left nut g ₂ attached to the basic rail R ₂ , and the reduced diameter part 42 at the tip of the male thread S ₂ forms the terminal part, and the distance between it and the basic rail R ₁ is The reduced diameter portion 42 is formed into an elliptical shape, and is firmly clamped by a gripping member (not shown), and can be _tightened using a tool such as a spanner or a screwdriver.
The relaxation of n ₂ is facilitated. In the figure, T ₁ and T ₂ are the tip rails.

3-6 Action/Effect In this invention, when a train passes with the tip rail T ₂ in contact with the basic rail R ₂ on the right side,
Vibrations and shocks during passing are transmitted to the connecting rods 35 and 36, and some of them are also transmitted to the electric point machine Z, but the male screw of the connecting rod 35 on the basic rail _R2 side
The root diameter d ₂ of S ₂ is the outer diameter of the male thread S ₁ on the bottom plate 31 side.
Because it is larger than d ₁ , it has high resistance to vibration and shock, so wear and damage does not occur locally.
In addition, since the middle part m of the connecting rod 35 is cylindrical and only male screws are carved at both ends, the connecting rod 35 is simpler and cheaper to manufacture than conventional methods, and is particularly useful when turning. There is no risk of causing significant trouble, and there is no risk of crushing or damaging the screw threads due to contact between working equipment and the connecting rod during track compaction work, and there is no risk of the basic rail being tightened. Even when tightening at a certain part, the nut can be easily inserted into the connecting rod from the bottom plate side, and the nut can be quickly moved in a straight line toward the clamp in the cylindrical part in the middle of the connecting rod. This method is significantly more efficient than the conventional method in which the engraved middle part was moved one by one by rotating a nut, and it is also possible to grasp the middle part formed in a cylindrical shape or the tip of the front connecting rod. When clamping with members, the nut can be easily loosened, so the connecting rod can be quickly and easily replaced, making replacement virtually impossible and removing the connecting rod by cutting, fusing, etc. Compared to conventional means, it is expected to significantly improve work efficiency, and it is also economical in terms of materials.Furthermore, the front connecting rod is connected only between the bottom plate and the basic rail near the bottom plate. Since the connecting rods are only interposed, the task of compacting the track can be carried out extremely easily.Moreover, compared to the conventional type in which connecting rods were attached to the front and rear basic rails, the present invention has Since some of the cables can be omitted, the effort and cost for laying the cables is reduced, and equipment costs are also reduced, making it more economical than conventional methods.It also saves time and effort during maintenance and inspection. This has practical benefits such as being able to reduce the amount compared to conventional methods.
