Abstract

The invention relates to a rail joint clamping device. The rail joint clamping device comprises a fishplate which is clamped between the two sides of a rail, a chuck used for clamping the fishplate towards the rail, and a force application unit, wherein a certain angle is formed between the force application unit and the horizontal plane, and the force application unit applies force to the chuck to enable the chuck to carry out clamping. The rail joint clamping device is convenient to install, high in reliability and long in service life. The rail joint clamping device is especially applicable to the occasions where the space between the rail bottom of the rail and a track bed is limited, such as the occasions of ballastless track beds in a rail track.

Description

technical field [0001] The invention relates to a rail joint clamping device used in emergency installation of railway rail joints and damage maintenance in the middle of the rails. Background technique [0002] In this field, the device that realizes the connection of two adjacent rails on the track is called a rail joint. [0003] The connection of conventional railway rails at home and abroad is mainly connected by fishplates. The structure of the rail joints includes fishplates arranged on both sides of the rails. The fishplates are fixed to the rails by bolts and spring washers, and are specially installed on the rails There is a gap between them to meet the requirements of thermal expansion and cold contraction of the rail. This connection method is also often used in emergency situations such as breakage of conventional rails, so that it can be used temporarily before the broken rails are too late to be repaired. The disadvantage of this connection method is tha...
