Abstract
The utility model relates to an emergency-type bolt used for railway tracks. The technical proposal of the utility model is as follows: the emergency-type bolt comprises two fishplates. The emergency-type bolt is characterized in that the bolt body is a U-shaped clamp; one end of the U-shaped clamp is provided with a support arm which is bent inwards; the support arm props up the interior of the attachment hole of one fishplate; the other end of the U-shaped clamp is provided with a pressure bolt; the end of the pressure bolt props up the interior of the attachment hole of the other fishplate. The emergency-type bolt is simple in structure, which can quickly connect ordinary steel rails and unperforated steel rails when the emergency bolt is used together with ordinary clamping plates (fishplates).
Description
Technical field
The utility model relates to the emergency bolt that railway track is laid usefulness.
Background technology
For adapting to the requirement of present rail track laying construction gapless track, in construction, tend to occur the situation of driving while constructing according to on-site actual situations, perhaps be in an emergency when needing to meet an urgent need, common rail joint connects complicated, take a lot of work, time-consuming, its main cause be bolt with sleeper between cooperate complicatedly, and can't realize quick-replaceable purpose.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, be used with common clamping plate and can finish the emergency bolt that common rail, atresia steel rail laying joint are used fast.
For this reason, the technical solution of the utility model is: the emergency bolt, comprise two splice bars, and it is characterized in that: bolt body is a U type card, and an end of U type card is provided with aduncate support arm, and the support arm roof pressure is in the connecting hole of a splice bar; The other end of U type card is provided with hold-down bolt, and the end roof pressure of hold-down bolt is in the connecting hole of another piece splice bar.
Beneficial effect:
The utility model is simple in structure, be used with common clamping plate (splice bar) and can finish being connected of common rail, atresia rail fast, its easy construction, and every complete equipment cooperates a secondary common fishtail clamping plate to use, and has saved time, raw material.Use in the engineering that the utility model can also need be fixed, clamp at other.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, with diameter 30mm round steel 1, making the also interior mutually bending of U type has support arm, cylinder table scalariform 2 is made on the support arm top, its length is no more than the thickness of splice bar, during use, pass rail 3 below, insert in the connecting hole 5 of splice bar 4, other end correspondence is provided with nut 6, and bolt 7 is arranged on the nut, and the top of bolt 7 is provided with corresponding cylinder step, directly twist bolt 7 and just can clamp splice bar quickly, thereby reach the purpose that clamps rail.Every complete equipment cooperates a secondary common fishtail clamping plate to use.
