Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a mounting bracket for a floor plate heating type electric snow melter that protects switching points of railway tracks from snow melting in winter from freezing.

[Conventional technology]

In railways, it is extremely important for rail transport to ensure that rail switching points are protected from snow melting from freezing in winter to ensure smooth rail switching.

For this reason, electric snow melters have traditionally been installed on the sides of floorboards to prevent freezing at points.
For this mounting bracket, for example,
There is something like the one shown in the publication.

To explain this based on FIG.
Long metal (iron) rods 1 and 1' of books are arranged in parallel with a slight interval, and their rear ends are connected by a connecting plate 2. ′
is rotatably supported on a shaft 3. A wide channel type fastening fitting 4 is fitted from above to the front end of the long rods 1, 1' so as to hold both rods 1, 1' together. A vertical piece 4a of a fastening fitting 4 is attached to the outer surface of the rod 1.
An insertion groove 1b into which the clamping member 4 can be inserted is formed, and the lower edge of the vertical piece 4b is horizontally bent inward to form a detachment prevention piece 4c to prevent the fastening fitting 4 from detaching. The metal fitting body is fixed to the floorboard 5 by welding the long rod 1 to the side surface of the floorboard 5.

To install the snow melter 6, open both rods 1 and 1' slightly, insert the bar-shaped sheath linear snow melter 6 deeply into the arcuate grooves 1a and 1'a, and then attach the long rod 1 on the non-fixed side. ' is pressed against the snow melter 6 to create a slight space between the long rod 1' and the vertical piece 4b on the non-insertion side of the fastening fitting 4, and a wedge 7 is driven into this space to prevent it from coming off. This is done by inserting a pin 8 and firmly tightening and fixing the snow melter 6 between the long rods 1 and 1'.

[Problem that the invention attempts to solve]

However, in cold weather, when inserting the retaining pin after driving the wedge 7 as described above, the length of the retaining pin is approximately 3 mm, so when removing gloves and inserting it, your hands may freeze. This could not be done easily.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a mounting bracket for a floorboard heating type electric snow melter that allows the snow melter to be easily and easily installed during cold weather.

[Means for solving problems]

In order to achieve the above object, the present invention uses a long flat plate member as a fastener that is press-fitted between the long rod on the non-fixed side and the vertical piece on the non-inserted side of the fastening fitting to urge them apart. It is characterized by using a plate spring member which is bent into a substantially U-shape and has an engagement recess formed in one of the bent pieces to engage with the vertical piece on the non-insertion side of the fastening fitting. be.

[Effect]

Therefore, the leaf spring member can be easily assembled by pressing one end of the leaf spring member by hand and sliding it between the long rod on the non-fixed side and the vertical piece on the non-insertion side of the fastening fitting. can be installed.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4. The same elements as those in the conventional example shown in FIG. 5 will be described with the same reference numerals.

FIG. 1 shows the mounting hardware for the floorboard heating type electric snow melter. The mounting hardware consists of two long metal rods 1, 1' made of iron or the like that hold the snow melter 6, and the long rods 1, 1'.
1', and a plate spring member 10 which is compressed and inserted between the elongated rod 1' and the clamping member 4 and firmly tightens and fixes the snow melter 6.

The long rods 1 and 1' are arranged in parallel with a slight interval, and arcuate grooves 1 are formed on opposing sides over the entire length.
a, 1'a are formed, and these long rods 1,
The rear ends of the long rods 1' are connected by a connecting plate 2, and one long rod 1' (on the right side in FIGS. 1 to 4) is rotatably supported on a shaft 3, and the long rods 1, The front end of 1' can be opened and closed.

As shown in FIG.
is fitted from above so as to hold both rods 1 and 1' together, and for this fitting, there is an insertion groove on the outer surface of the long rod 1 into which the vertical piece 4a of the fastening fitting 4 can be inserted. 1b is formed, and on the other hand, in order to prevent the fastening fitting 4 from coming off, the lower edge of the vertical piece 4b is horizontally bent inward to form a separation preventing piece 4c. The mounting bracket body configured in this way is attached to the floorboard 5 by welding the left long rod 1 to the side surface of the floorboard 5 fixed on the upper surface of the sleeper 11.
is fixed.

To attach the snow melter 6 to the long rods 1, 1' and the fastening fittings 4 installed as described above, open the front ends of both rods 1, 1' slightly (see Fig. 2), and open the opposite sides of the snow melter 6. Deeply insert the bar-shaped sheath linear snow melter 6 into the arcuate grooves 1a, 1'a (see Fig. 3), then press the long rod 1' against the snow melter 6 to tighten the long rod 1' and the fastening fitting 4. A slight space is formed between the vertical piece 4b (see Fig. 3), and a leaf spring member 10 as a fastener is compressed in this space, and the snow melter 6 between the long rods 1 and 1' is
This is done by firmly tightening and fixing (see Figure 4).

The leaf spring member 10 is made by bending a long flat plate member into a substantially U-shape, and has an engagement recess 1 in the bent piece that engages with the vertical piece 4b on the non-insertion side of the fastening metal fitting 4.
0a, and when installing it, press the end piece with your hand and narrow it in the compression direction, and then
and the vertical piece 4b of the tightening fitting 4, and insert the engaging recess 10a between the vertical piece 4b of the tightening fitting 4.
It is contracted by engaging with. Therefore, the leaf spring member 10 can be easily attached, and the long rod 1' and the vertical piece 4b can be biased in the direction of separation, and the snow melter 6 between the long rods 1 and 1' can be easily attached. can be firmly tightened and fixed.

[Effect of idea]

As described above, the present invention involves inserting a snow melter between two long rods held by a channel-type fastener, and press-fitting the fastener to tighten and fix the snow melter to the floorboard. In the mounting bracket for an electric snow melter, a long flat plate member is bent into a substantially U-shape as the fastener, and the bent piece is engaged with a vertical piece on the non-inserted side of the fastener. Since a leaf spring member with a mating recess is used, press one end of the leaf spring member by hand to deflate it, insert it into the specified location,
Can be easily installed between the long rod and the fastening fitting. Therefore, there is no inconvenience in driving work in cold weather, unlike when conventional wedges and retaining pins are used.
