Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rail fixing device for fixing a rail to a sleeper.

Various types of devices for fixing rails to sleepers have been used in the past, and fixing devices such as dog nails, bolts and nuts, welding, and holding bottles are generally known.

All of these have advantages and disadvantages; dog nails are relatively easy to install and remove, but they do not maintain sufficient adhesion and are not suitable for high-speed railway rails. ! With the bolt/nut method, it is time-consuming to install and remove the rail, and frequent maintenance and inspections are required to ensure that the rail is securely held. On the other hand, when welding means is used, although it is sufficient to securely hold the rail, the installation and removal operations are troublesome and the workability is extremely poor.

From this point of view, there is a need for the development of an inexpensive fixing device that can easily and quickly attach and detach rails to sleepers, regardless of whether they are lightweight rails or heavy rails, and that can ensure reliable fixation over a long period of time. It's here.

Therefore, an object of the present invention is to provide a rail fixing device that satisfies such requirements.

For this purpose, according to the present invention, there are provided clip internal portions which are provided in pairs across the rail leg portions and project flatly and which define the rail seat portions, and one end of which is connected to each chrysos Il'i': fixed portion. and a rail 1151 fixed clip member whose front end is in contact with the upper surface V of the rail leg, each clip fixing E'AI having a generally rectangular clip fitting opening for receiving one end of the rail identifying clip member. , 1 for each rail j
1" 11 fixed clip members each 1") Tsuzo fitting b
Step part and clip that locks on one side line inside i-10
- A rail fixing device is provided, which is characterized in that it includes an H portion that abuts the peripheral edge of the clip fitting 611 on the soil surface of one constant portion.

With the IJ-1 fixed device constructed in this way, it is easy to use a hammer or the like to drive the rail fixing clip member toward the clip fitting opening of the clip fixing part on the sleeper and the upper side of the rail leg. In this case, the shoulder part of the clip member is configured to come into contact with the top surface of the clip fixing part and stop, thereby preventing over-driving and ensuring a reliable engagement. be able to. Also, when removing it, all you have to do is pull it out using all the leverage you have at ζ.

According to one embodiment of the present invention, the rail fixing portion is constructed integrally with the sleeper, and in this case, the sleeper itself can be made entirely of metal and manufactured using a press or the like.

In addition to this, traditional wooden or concrete lj-! ! ! It can be made lighter than Q sleepers, and can be particularly advantageous in terms of transportation and workability.

In another embodiment, the rail fixing part is constructed separately from the sleepers, and the rail fixing parts are configured separately from the sleepers, and are made of conventional sleepers (e.g. wooden, concrete, etc.).
(made of steel) suitable mounting means may be used.

Hereinafter, some embodiments of the present invention will be described with reference to the accompanying drawings.

1st. ．． FIG. 2 shows an embodiment of the present invention, where l is a rail, which is seated on the rail seat portion 3 of a steel sleeper.

This rail seat portion 3 is defined by a pair of flatly protruding clip fixing portions≠. The sleeper λ is shown in Figure 2.
It has a cross-sectional shape like this. Each of the clip fixing portions protruding from the flat surface has a substantially rectangular clip fitting rotor formed in the central portion thereof. 6 is a rail fixing clip member; As shown in Figures 1 and 5, one of the leg portions 7 is formed so as to be inserted into the clip f03 fitting opening j, and there is a step latched to one side edge ta inside the clip fitting opening j. The upper surface of the portion 7a and the clip fixing portion ≠ the periphery of the clip fitting opening a
It is provided with a shoulder portion 7b that abuts on the shoulder portion 7b. The other leg portion g of the clip member B is configured to come into pressure contact with the leg portion /a of the rail l. In FIG. 7, io is an insulating pad and a support member. Insert each clip member 6 toward the leg portion la of the rail l, insert the tip 7C of one leg portion 7 into the clip fitting opening j of the clip fixing S≠, and drive it diagonally downward, so that the shoulder portion 7b is fitted with the clip. It is mounted as shown in FIG. 1 by forcibly fitting it to a position where it abuts the edge lla around the opening j. As a result, the rail l is firmly fixed and held on the rail seat portion 3 of the sleeper. Each clip fixing portion should be formed so that stress is not concentrated near its clip fitting opening j. Moreover, since each clip fixing part μ has a substantially flat protruding shape, it can be easily formed by press working. By configuring the sleepers in this way, not only can the sleepers themselves be made lighter, but they can also be transported without being bulky by stacking them on top of each other.

Figure 6 shows rail/l as sleeper/, rail seat part of 2/3
An example is shown in which the clip is seated directly on the top, and each clip fixing part/≠,
Opening/! The structure of the clip member/B is the same as that shown in FIG.

FIG. 7 shows an example in which a separately made clip fixing part iz is planted on a concrete sleeper 17 and the rail 20 is fixed with a lip member similar to that in FIG. 1. in this case,
The two clip fixing parts l♂ may be integrated and configured to receive the legs of the rail 20 between them.

As explained above, according to the present invention, it is extremely simple.
Tsuna 4'l? A useful rail nationally specified device is provided which is easy to install and remove, and which provides a reliable and strong fixing and holding action over a long period of time with little need for maintenance and inspection. Furthermore, according to this invention, evening, 1 and t are r.
It can be applied as a 1.51 fixed device for all kinds of rails, regardless of whether r+b-ti;-1i7L or 1,1).
