Description

Railroad Rail Fastening Device

The present invention relates to a railway rail fastening device for a phase, and more specifically, as a track change occurs between a rail and a rail between a rail and a rail when a train is driven, a control pad is inserted into a base plate during a correction operation and corresponding thereto. By using a clip hook, the present invention relates to a railroad rail fastening device for a phase that easily performs a tube or step and line alignment correction operation.

In general, in the railway rail section, vibrations are distributed evenly on the roadbed via rails and sleepers, and the vibrations are reduced evenly by rails and sleepers, and vibrations are reduced. It is composed of gravel-shaped tracks to perform various functions such as preventing resistance, absorbing vibration of trains, improving ride comfort, facilitating rainwater drainage, and preventing weeds from growing.

As shown in Figure 1, the type of base plate (1) currently in use is for general use (usually sleepers), branch (for branch sleepers), seam for use (seam sleepers) and bridge sleepers (3) for general use base plates (1) is used, even if the bridge sleeper is correctly processed and laid, the riveting bolts (head) of the plate girders (meter type and neck type) are tightly attached to the top of the girder under the train passing load. As a result, gaps and alignment deformations are generated (especially in the case of curved bridges), so the repair work must be repeated several times.

However, as the track is damaged by the use of train operation, it compares the high and low points between two points, and when the height is decided according to the distance between two points when maintaining a constant slope, the high and low design designed for the terrain is deformed. In addition, there was a problem that the gap is deformed.

Here, the gauge refers to the distance between two railroads, where 60% of the world's railroad is a standard gauge of 1435 mm (4 ft 8½ in). The gauge wider than the standard gauge is called the wide gauge and the gauge narrower than the standard gauge is called narrow gauge.

Accordingly, as the direction of the track is deformed and frequent maintenance work is required, the spike screw 5 which is fastened to the base plate 1 during dismantlement and alignment alignment is dismantled, repaired and refastened, and the base is used for surface alignment work. In order to correct sag by inserting a pad between the plate 1 and the sleeper 3, the spike screw 5 is also dismantled and then refastened.

Accordingly, since the spike screw 5 hole of the bridge sleeper 3 must be drilled again adjacent to the existing drilling position, the bearing capacity of the bridge sleeper 3 is weakened and the lifespan is shortened. There is a risk of the tightness is very important bar, once used spike screw (5), as well as the corresponding screw thread damage of the nut there was a problem that must be replaced after repair.

In addition, due to the hassle of work, high manpower, budget investment, and delayed train due to the suspension of train operation, deterioration of the reliability of the railway and weakness of safety are inevitable. It is urgent.

Accordingly, the present invention has been made in order to solve the above problems, the object of the present invention, the fastening to prevent the deviation in the tilting, double and transverse direction caused by the gap and the step between the rail and the rail when running the train The control pads installed on the bottom of the means and rail continuously reduce the occurrence of wave wear, noise and vibration of the rail, and by using only the fastening means and the adjustment pad without removing the base plate during maintenance work due to the step difference of the rail. As a result of the rapid repair, it provides a railroad rail fastening device for safety and work efficiency and efficiency.

Characteristic of the railroad fastening device for the railroad according to the present invention for achieving the above object, the base plate is fixed to the sleeper (3) by the spike screw (5), the rail (7) is seated in the center of the upper surface ( 100, the control pad 200 interposed between the base plate 100 and the rail 7 and the bottom of both sides of the rail 7 seated at the center of the base plate 100 can be fixed and detached. Consists of fastening means 300 is installed so as to, the base plate 100 is a control pad seating portion 120 formed on the central upper surface of the body 110, and a predetermined interval on both sides of the control pad seating portion 120 A plurality of screw holes 170 are formed at predetermined intervals from both side edges of the fastening part 130 and the body 110, which are formed to have a shape.

As described above, the in-vehicle railroad rail fastening apparatus according to the present invention is a curved bridge or bridge according to the effect that can be pipe or step difference and alignment correction without dismantling the spike screw for fixing the base plate on the sleeper Or the scope of application, such as piers have a variety of effects.

In addition, the safety of the worker is improved by reducing the work tools (impacter, perforator, generator, etc.) and manpower waste due to the dismantling of the spike screw, and the semi-permanent use is possible, thereby reducing the accompanying costs.
