The adhesive reinforcement is a low-cost, low-energy-consumption and pollution-free repair technology, and is gradually mature in continuous popularization and application. However, in the long term development, the technology still has certain improvement space in the aspect of using matched equipment.

The repair splint directly decides the safety performance after the steel rail is repaired to a certain extent as one of main equipment that the adhesive reinforcement repair technology utilized, but the existing repair splint mainly fixes the damaged steel rail and two main and auxiliary plates by a bolt group in structural design, and the bolt group on the basis has no anti-drop structure of a nut, but can generate great vibration when a train runs, can lead to the falling of the nut for a long time, further leads to the falling of the repair splint, and causes serious consequences.

SUMMERY OF THE UTILITY MODEL

The utility model aims to: in order to solve the problems, a combined damaged steel rail repairing clamp plate is provided.

In order to achieve the purpose, the utility model adopts the following technical scheme:

the utility model provides a splint are restoreed to modular impaired rail, includes the impairment guide rail, fixes the restoration splint body in impairment guide rail both sides through bolt group, bolt group is including multiunit screw rod and nut, multiunit the rectangular channel has all been seted up to the junction of screw rod and nut, just the inside spacing portion that is equipped with the nut butt of rectangular channel.

Preferably, spacing portion is including fixing at the rectangular channel elastic component, the elastic component top is fixed with the stopper, just the stopper joint is inside the rectangular channel to with the nut butt.

Preferably, the elastic component comprises a telescopic rod and a spring sleeved outside the telescopic rod, and the telescopic rod and the spring are both fixed between the bottom of the limiting block and the bottom of the rectangular groove.

Preferably, the top of the limiting block is of an inclined structure, and the inclined edge is located in the rectangular groove.

Preferably, the vertical end of the screw rod is provided with a through groove, and the through groove penetrates through the screw rod and is communicated with the rectangular groove.

In summary, due to the adoption of the technical scheme, the utility model has the beneficial effects that:

in this application, when the bolt group will injure the guide rail and fix, the nut can earlier contact with the stopper with the screw rod in the connection process, can compress the stopper always when the nut is tightened and get into the rectangular channel at screw rod top completely until the stopper in, screw rod and nut back of screwing, the nut just separates with the stopper, the stopper plays and outstanding screw rod card through the spring in nut and rectangular channel, make the nut can't remove under great vibrations, can't drop, guarantee to restore permanent use of splint and use.
