AI Technical Summary
In the existing technology, after the elastic clip is installed, the tangent point between the shim and the top arc of the elastic clip is not on the same plane, which may cause some of the shims of the elastic clip to slide towards the rail, resulting in excessive torque and reducing the firmness of the rail fixation.
The installation structure of the small-radius curved spring clip is adopted. By inserting the spring clip body and the expansion bolt at a 45-degree angle and using an anti-slip pad to increase friction, it is ensured that the tangent point of the clip and the top arc of the spring clip are on the same plane. The downward force applied by the nut is used to disperse the pressure and avoid damage to the spring clip.
It effectively reduces the torque during installation, increases the stability of the clips on the ground, improves the fixing firmness of the rails, and extends the service life of the spring clips.

[0002] When rail is installed, the main role of elastic sheet is mainly reflected as important component part of railway track fastener system. With the function of fixed rail, keep gauge, buffer shock attenuation and height adjustment. Elastic sheet is closely fixed on sleeper or track foundation by cooperating with bolt, nut and other fasteners, to ensure that rail does not move horizontally or longitudinally in the process of train operation.
[0003] In prior art, after installation, the tangent point of gasket and the top arc of elastic strip is not on the same plane, which can cause the gasket of part of elastic strip to slide to rail, and cause excessive torque during installation, reduce the firmness of rail fixation. UTILITY MODEL CONTENT
[0004] The utility model aims at providing a kind of installation structure of small radius curve elastic strip to solve the problem that the gasket of part of elastic strip can slide to rail, and cause excessive torque during installation, reduce the firmness of rail fixation.
[0005] In order to realize the above-mentioned utility model purposes, the utility model adopts the following technical solutions: a kind of installation structure of small radius curve elastic strip, including rail, the rail is detachably arranged on the ground, two expansion bolts are arranged on the ground, a buckle is arranged on the ground, the top surface of the buckle is provided with elastic strip body, the buckle and the expansion bolt are rotatably inserted, and the elastic strip body and the expansion bolt are rotatably inserted.
[0006] Preferably, the angle between the center line of the elastic strip body and the ground is 45 degrees.
[0007] Preferably, the expansion bolt is threadedly connected with a nut.
[0008] Preferably, the expansion bolt is fixed with a fixing ring, and the bottom surface of the fixing ring is attached to the ground.
[0009] Preferably, the top surface of the ground is fixed with two anti-skid pads, and the anti-skid pads support one side of the buckle upward.
[0010] Preferably, the expansion bolt is slidably inserted with a gasket, and the gasket is between the nut and the elastic strip body.
[0011] Compared with prior art, the installation structure of small radius curve elastic strip with the above technical solutions has the following beneficial effects:
[0012] First, during installation, the workers will install the rail on the ground. Then, they will screw two expansion bolts into the ground. Next, they will insert the fastening clip and the elastic clip body onto the expansion bolts, ensuring that both ends of the fastening clip are on the rail and the bottom surface, respectively. At this point, the tangent point of the arc at the top of the fastening clip and the elastic clip body are on the same plane, which can prevent the fastening clip from sliding towards the rail, reduce the torque during installation, reduce the sliding angle between the fastening clip and the elastic clip body, ensure the fastening force, and increase the firmness of the rail fixation.
[0013] Second, since one end of the fastener is pressed against the top surface of the anti-slip mat, the friction between the fastener and the ground is increased, thereby increasing the stability of the fastener's position on the ground. The worker will use the downward-screwing nut to apply a downward force to the spring clip body, which in turn will cause the spring clip body to apply a downward force to the fastener. At this time, the washer will disperse the pressure applied by the nut to the unit area of the spring clip body, preventing the spring clip body from being damaged, thereby increasing the service life of the spring clip body.
