Abstract

The utility model relates to a track connecting plate belonging to the field of traffic facilities, which comprises an inner connecting plate and an outer connecting plate clamped at the joint of two sections of a track and the inner connecting plate is connected with the outer connecting plate by bolts. The section of the inner/outer connecting plates take a shape similar to a letter ''k'', and the inner/outer connecting plates are assembled on the inner and outer side of the track respectively; wherein the distance between the stamping face of the inner connecting plate and the stamping face of the track is equal to the height of the wheel hub, while the stamping face of the outer connecting plate is as high as that of the track. The utility model has the advantages of lightening bumping noise, impact load as well as mechanical abrasion, helpful to improve comfort for passengers, expanding service life for the vehicle, lowering energy exhaustion as well as cost for running.

Description

Track connecting plate

1, technical field: track connecting plate of the present utility model belongs to field of traffic facilities, relates in particular to a kind of railroad track.

2, background technology: the employed junction plate of the interorbital connection of China railways all belongs to embedded at present, outside promptly in every joint rail connection, be slightly with section that " two junction plates of [" shape are embedded in the rail groove, junction plate is lower than orbital plane, use bolton, the influence of expanding with heat and contract with cold and brought with elimination in certain slit is reserved in the rail connection.Since the impact noise that seam crossing produces, shock loading, and mechanical wear etc. have reduced passenger's the comfort level and the application life of locomotive, have increased energy consumption, and running cost is increased, and have caused unnecessary waste.

3, summary of the invention: the purpose of this utility model is to propose a kind of track connecting plate that reduces impact noise and mechanical wear.

The purpose of this utility model is achieved in that track connecting plate is by the inside and outside junction plate that is clamped in two joint track seam crossings, be inter-connected via a bolt joint and form, inside and outside junction plate section slightly is " k " font, be installed in the track medial and lateral respectively, wherein, the distance of interior junction plate tread and track tread is equal to the height of hub for vehicle wheel, and the outside link plate tread flushes with the track tread.

Owing to adopt technique scheme, when wheel passed through the track seam, the hub tread only contacted with the outside link plate tread, and does not contact with track two joints; The wheel hub tread contacts with interior junction plate tread, has increased the contact area of wheel and track, thereby:

1. alleviated impact noise, shock loading and mechanical wear, avoided rail joint to be pressed into the shape of a saddle, roadbed extrudes flange of rail hole, also helps improving simultaneously the speed of a motor vehicle;

2. keep original rail gap, heat energy rises, cold energy contracts, and can avoid the high temperature runway, and the situation that low temperature is broken track takes place;

3. easy for installation, be convenient to maintenance;

4. be convenient to Rolling Production in batch, recondition expense is cheap, and is safe and reliable.

4, description of drawings: concrete structure of the present utility model is provided by following drawings and Examples:

Fig. 1 is the fundamental diagram of wheel when passing through the track seam;

Fig. 2 is the track connecting plate full sectional view;

Fig. 3 is the track connecting plate vertical view;

Fig. 4 is the track connecting plate left view;

Fig. 5 is an original track junction plate full sectional view.

Legend: 1, hub 2, wheel hub 3, interior junction plate 4, outside link plate 5, bolt 6, track.

5, the specific embodiment:

Embodiment: shown in Fig. 1-5,, the inside and outside junction plate 3,4 that section slightly is " k " font is installed respectively in the medial and lateral of per two joint tracks, 6 seam crossings.Wherein, the distance of interior junction plate 3 treads and track 6 treads is equal to the height of hub for vehicle wheel 2, and outside link plate 4 treads flush with track 6 treads.Inside and outside junction plate 3,4 interconnects by bolt 5.

Claims

1, a kind of track connecting plate, by the inside and outside junction plate that is clamped in two joint track seam crossings, be inter-connected via a bolt joint and form, it is characterized in that: inside and outside junction plate section slightly is " k " font, be installed in the track medial and lateral respectively, wherein, the distance of interior junction plate tread and track tread is equal to the height of hub for vehicle wheel, and the outside link plate tread flushes with the track tread.
