Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a mounting bracket for a basic rail heating type electric snow melter.

[Conventional technology]

Melting snow at switching points on railway tracks is extremely important for transportation. Therefore,
A snow melter is attached to a railway track, and a conventional mounting bracket for a snow melter is as shown in, for example, Japanese Utility Model Publication No. 48-6241.

To explain this based on FIGS. 3 and 4, a retaining flat metal fitting 3 to be pressed against the lower surface of the bottom 2 of the basic rail 1 is attached to the retaining bent piece 3a at the tip of the bottom 2 of the basic rail 1. It is arranged so as to be hooked to the side surface, and shaft supports 4, 4 are provided on the left and right sides of the rear end, and a horizontal shaft 5 is mounted on these supports and is locked with a cotter pin 6. A substantially L-shaped push fitting 7 consisting of a horizontal plate portion 7a and a vertical plate portion 7b is fitted to the horizontal shaft 5 using shaft rings 8, 8 provided on the left and right sides of the horizontal plate portion 7a, and pressed. The metal fitting 7 is made freely rotatable back and forth, rectangular openings are provided in the vicinity of the shaft support of the presser flat plate metal fitting 3 and the horizontal plate portion 7a of the pressing metal fitting 7, and a pressing spring 9 is wound around the horizontal shaft 5.
One end 9a of the presser spring 9 is pressed against the back surface of the presser flat metal plate 3, and the other end 9b is pressed against the horizontal plate 7 of the presser metal 7.
The push metal fitting 7 is always forcefully tilted toward the rail 1 side by being pressed against the upper surface of the rail 1.

Further, a channel type holding fitting 10 is fixed to the front surface of the vertical plate portion 7b of the push fitting 7 by welding or the like.
The sheathed wire casting type heating plate 11a, which is the main body of the heating plate 1, is tightly pressed and held against the rail belly surface in a hugged state. Note that 11b is a terminal box of the snow melter 11.

[Problem that the invention attempts to solve]

By the way, according to the above-mentioned snow melter mounting bracket, the snow melter body is attached by simply holding the snow melter body with a channel-type holding bracket and pressing it against the belly surface of the rail 1, so that trains cannot pass. When this happens, the railway track flexes a little, especially when the brakes are applied, and as this happens over and over again, the snow melter itself ends up slipping sideways from the channel-type holding bracket.

Therefore, the present invention aims to improve the above-mentioned mounting bracket,
To provide a mounting bracket for a basic rail heating type electric snow melter in which the snow melter main body does not slip laterally from the holding bracket even if the rail is frequently bent.

[Means for solving problems]

In order to achieve the above object, the present invention has a horizontal shaft mounted on the front end of a presser flat plate metal fitting that presses against the lower surface of the bottom of the basic rail.
A push metal fitting in the shape of a letter is rotatably supported, and a pressing spring is wound around the horizontal axis so that the push metal piece is always tilted toward the rail, and a flat snow melter body is attached to the vertical plate portion of the push metal fitting. The mounting bracket for a basic rail-heating electric snow melter is provided with a channel-type holding fitting that presses against the rail, and is characterized in that a locking protrusion that projects toward the snow melter main body is formed on the web of the channel-type holding fitting. .

[Effect]

Therefore, by setting the mounting bracket of the present invention at the bottom of the rail, holding the snow melter body with the channel type holding fitting, and then hitting the vertical plate part of the holding fitting or push fitting with a tool such as a mallet. A locking protrusion formed on the web of the holding fitting is inserted into the snow melter main body, and it is possible to prevent the snow melter from shifting laterally.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. The same elements as those in the conventional example shown in FIGS. 3 and 4 will be described with the same reference numerals.

On the lower surface of the bottom portion 2 of the basic rail 1, a presser flat plate metal fitting 3 having a hooking bent piece 3a formed at its tip is arranged.
Pivotal supports 4, 4 are formed on the left and right sides of the rear end, and a horizontal shaft 5 is mounted on these supports and secured with split pins 6. A substantially L-shaped push fitting 7 consisting of a horizontal plate portion 7a and a vertical plate portion 7b is attached to the horizontal shaft 5 by fitting shaft rings 8, 8 provided on the left and right sides of the horizontal plate portion 7a. It is pivoted so that it can rotate in the front and rear directions. In addition, rectangular openings are provided near the pivot points of the presser flat plate metal fitting 3 and the horizontal plate portion 7a of the presser metal fitting 7, respectively, and a pressing spring 9 is wound around the horizontal shaft 5, and one end portion 9a of the pressing spring 9 is provided. By press-contacting the presser to the back surface of the flat plate metal fitting 3, and pressing the other end 9b to the upper surface of the horizontal plate part 7a of the presser metal fitting 7,
The pusher 7 is always strongly tilted toward the rail 1 side.

A channel-type holding fitting 15 for holding the sheathed wire casting type heating plate 11a, which is the main body of the snow melter 11, is fixed to the front surface of the vertical plate portion 7b of the holding fitting 7 by welding or the like, and is attached to the web 15a. There are three locking protrusions 1 toward the protruding direction side of the flange 15b, that is, toward the sheathed wire casting type heating plate 11a side.
6, 16, 16 are formed protrudingly.

The flat plate-shaped sheathed wire casting type heating plate 11a, which is the main body of the snow melter 11 for melting snow on the railway track 1, is wrapped in a malleable and ductile metal such as aluminum. To install the heating plate 11a, hold it with the channel-type holding fitting 15 and firmly press it against the rail belly surface, and then use a tool such as a mallet to press the vertical plate portion 7b of the push fitting 7 or the holding fitting 1.
5, the locking protrusions 16, 16, 16 of the holding fitting 15 are press-fitted into the cast metal of the heating plate 11a.

Therefore, even if the basic rail 1 is often bent due to the passage of trains, etc., especially due to braking, the locking protrusion 16
By press-fitting, the sheathed wire casting type heating plate 11a does not shift laterally with respect to the channel type holding fitting 15.

In the above embodiment, the locking protrusion 16 is
Although the description has been made regarding the actual formed one, the number is not limited to three, and may be one, two, or even four or more.

[Effect of idea]

As described above, in the present invention, a locking protrusion that protrudes toward the snow melter body is formed on the web of the channel-type holding fitting that presses the flat plate-shaped snow melter main body against the rail. After holding the snow melter, by hitting the vertical plate part of the holding fitting or push fitting with a tool such as a mallet, the locking protrusion formed on the web of the holding fitting can be press-fitted into the snow melter body. Even if the rails are often bent due to passing trains or braking, the snow melter body will not slide sideways from the channel-type holding bracket, and the snow melter body can be securely installed.
