Description
Technical Field
The utility model relates to a guard rail backing plate structure with adjustable use on wooden sleeper circuit.
Background
In the metallurgical industry, due to the limitation of conditions such as terrain, process and the like, a plurality of small-radius curves (the radius of the curve R is less than 200 meters) are designed and laid on railways, and in recent years, the phenomena of serious damage of railway small-radius curve lines, short service life of steel rails stranded on the curves, damage of connecting parts, over-limit of curve track gauge, poor direction and the like are caused, so that the maintenance cost of the railway lines is greatly increased.
At present, most of the guard rail structure arrangement is in a fixed type spacing iron form, and the fixed type spacing iron form has a plurality of problems: (1) the fixed structure is that it is consuming to use the interval iron to assemble (2) the guardrail with bolt for main rail and guardrail and grind, and when the rim groove size exceeded 70mm, the guardrail will lose the effect of protection main rail, need all disassemble guardrail and main rail, just can change this kind of structure scene of guardrail (3) and need frequently change the guardrail. (4) The railway maintenance workload and the railway maintenance cost are increased.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a guard rail backing plate structure with adjustable use on wooden sleeper circuit breaks original interval iron connection structure form, reduces the waste that produces in the railway maintenance.
In order to solve the technical problem, the utility model adopts the following technical scheme:
the utility model provides a guardrail backing plate structure with adjustable use on wooden sleeper circuit, includes the backing plate, main rail, pressure rail iron and rail brace have set gradually on the backing plate, the one end of pressure rail iron is pushed down the lower part side of main rail, be provided with the guardrail on the pressure rail iron, the bolt passes in proper order guardrail and rail brace are fixed by the nut, the guardrail with still selectively be provided with U type trimmer between the rail brace, the bolt by the U type opening of U type trimmer passes.
Further, the backing plate is made of a Q235 steel plate with the thickness of 25 mm.
Furthermore, the rail pressing iron is made of a Q235 steel plate with the thickness of 36mm, and one side of the rail pressing iron is of a slicing structure so as to press the rail bottom of the main rail to prevent the main rail from tipping.
Furthermore, the main rail adopts a 60Kg/m steel rail.
Furthermore, the guard rail is a 43Kg/m steel rail.
Further, the U-shaped adjusting sheet has a size of 140 × 90mm, and an opening width of phi 25 mm.
Further, the U-shaped adjusting sheet comprises three adjusting sheets with the thicknesses of 3mm, 5mm and 10 mm.
Compared with the prior art, the utility model discloses a beneficial technological effect:
the guard rail structure with adjustable adoption is more stable than spaced iron formula structure, and when the rim groove size exceeded 70mm, the accessible increased U type gasket adjusted the size, need not change the guard rail, can reduce the cost of overhaul, and this kind of structure is easy and simple to handle, can operate the completion in railway transportation interval time, and then has promoted railway transportation efficiency.

Detailed Description
Example 1
As shown in fig. 1, an adjustable guard rail backing plate structure used on a wooden sleeper line comprises a backing plate 1, wherein a main rail 3, a rail pressing iron 2 and a rail brace 5 are sequentially arranged on the backing plate 1, one end of the rail pressing iron presses the lower side end of the main rail, a guard rail 4 is arranged on the rail pressing iron 2, and a bolt 6 sequentially penetrates through the guard rail 4 and the rail brace 5 and is fixed by a nut.
The backing plate 1 is made of a Q235 steel plate with the thickness of 25 mm. The rail pressing iron 2 is made of a Q235 steel plate with the thickness of 36mm, and one side of the rail pressing iron is of a slicing structure so as to press the rail bottom of the main rail to avoid the main rail from tipping. The main rail 3 adopts a 60Kg/m steel rail. The guard rail 4 adopts a 43Kg/m steel rail.
Example 2
As shown in fig. 2 and 3, a U-shaped adjusting plate 7 is further disposed between the guard rail 4 and the rail brace 5, and the bolt 6 is passed through a U-shaped opening of the U-shaped adjusting plate 7. The size of the U-shaped adjusting sheet 7 is 140 multiplied by 90mm, and the opening width is phi 25 mm. The U-shaped adjusting sheet 7 comprises three adjusting sheets with the thicknesses of 3mm, 5mm and 10 mm.
Application of U-shaped tab 7: when the size of the wheel rim groove exceeds 70mm, the size can be adjusted by increasing the U-shaped gasket 7 without replacing the guard rail, the overhaul cost can be reduced, the structure is easy and convenient to operate, the operation can be completed within the interval time of railway transportation, and the railway transportation efficiency is further improved.
The action process is as follows: when the guard rail is worn, the connecting bolt 6 is unscrewed, when the size of the wheel rim groove is measured to be 70mm, the U-shaped adjusting sheet 7 is inserted between the non-acting edge of the guard rail 4 and the rail brace 5, and after no gap exists between the non-acting edge of the guard rail 4 and the rail brace 5, the bolt 6 is screwed down.
The above-mentioned embodiments are only intended to describe the preferred embodiments of the present invention, but not to limit the scope of the present invention, and those skilled in the art should also be able to make various modifications and improvements to the technical solution of the present invention without departing from the spirit of the present invention, and all such modifications and improvements are intended to fall within the scope of the present invention as defined in the appended claims.
