Problems solved by technology

[0007] At this time, the existing elastic fastener 100' does not have a unit capable of preventing plastic deformation caused by an increase in stress under the action of an external force, so as figure 2 As shown, in the process of the rail 400 being lifted, the strain relationship caused by the stress increase under the action of the external force in the strain between the toe 30' and the front arch 20' is as follows: image 3 As shown, plastic deformation may occur, and after the plastic deformation, the fastening state of the rail 400 deteriorates to cause the product to lose its value, and also causes many safety accidents due to the loosening of the rail 400 from the fastening state.
[0008] For the above reasons, manufacturers of elastic fasteners have tried to develop elastic fasteners for railway track fixing that can prevent plastic deformation caused by increased stress under external force, but so far have not developed enough to utilize the installed Elastic fasteners for railway track fixing that prevent plastic deformation caused by increased stress under external force

Abstract

The invention relates to an elastic clip for fixing a railway rail and a method for installing the same. The tensile clip for securing rails of a railway according to the present invention also comprises: a head-arch having a leading end thereof inserted into a clip shoulder of a tie or a base plate; a first front-arch extending integrally from an end of the head-arch and rounded toward an upper side portion thereof; and a first toe extending integrally from the first front-arch and having an undersurface thereof contacting the top surface of a flange of a rail, wherein a second front-arch extends integrally from the leading end of the first toe and is rounded toward an upper side portion thereof, a second toe extends integrally from the leading end of the second front-arch and has a top surface at the leading end thereof contacting the undersurface of the head-arch, a head-arch leading end extension extends integrally from the other end of the head-arch for a certain length and forms a straight portion, and a third toe extends integrally from the leading end of the head-arch leading end extension, projects to the outside of the clip shoulder, and has a top surface at the leading end thereof that is rounded toward an upper side portion thereof. The elastic clip in the invention can prevent elastic clip plastic deformation caused by stress increase caused by load of a steel rail and a sleeper and friction force between track beds.

Description

technical field [0001] The present invention relates to an elastic fastener for fixing a railway track and a setting method thereof, in particular to an elastic fastener for fixing a railway track. The elastic fastener for fixing a railway track can not only firmly fix the rail, but also can When the rail is lifted during track bed laying and maintenance work, it prevents the plastic deformation of the elastic fastener caused by the stress increase caused by the friction between the load of the rail and the sleeper and the track bed, and is used through the extension of the front end of the head arch. The existing shoulder that has been installed on site, and the extension of the front end of the head arch is inserted into the shoulder to strengthen the fastening force with the shoulder. Background technique [0002] The railway track is fixedly arranged on the sleeper directly connected with the shoulder or the bottom plate with the shoulder. [0003] At this time, the rai...
