Track circuit residual voltage constant voltage shunting device Shaanxi Hongxin railway equipment

The 18706752192 track circuit residual pressure constant pressure shunting device of Shaanxi Hongxin Railway Equipment Co
, Ltd
is a constant pressure test tool developed in combination with the needs of the site to simulate the three elements of the wheel pressing on the rail: the contact form between the wheel and the rail contour, the contact position of the wheel on the rail surface and the weight of the wheel (24
5kn)
It is an effective test tool that meets the requirements of maintenance rules
It has the characteristics of small volume, light weight and convenient carrying, and can meet the test 43 Kg/m、50  Kg / m、60  Kg / m、75  Kg / Residual voltage of track circuit composed of M and other types of rails
Principle: the pressure splitter adopts & ldquo; Door type & rdquo; The structure is clamped on the rail head and installed on the rail with the torque / pressure conversion screw
Use the prefabricated torque wrench to turn the torque of the to the conversion screw, which is converted into pressure and acts on the pressure block
Through the arc surface of the pressure block, simulate the tread of the train wheel set and apply various levels of pressure without friction at 15 ~ 18mm from the center line side of the rail surface
Use of pressure shunting device: check and adjust the torque wrench: set the torque required by the torque wrench at the required position according to the torque / pressure conversion table (one-time setting can be used for a long time)
For example, when 1
5T (14
7kn) pressure needs to be applied to the rail surface, check and confirm that the torque of the torque wrench is set at 4
5kn 6 kg ▪ Meters (kgs▪ m)
At the same time, set the plate buckle of the rotation direction of the torque wrench
Adjust the anti slip: place the pressure splitter on the ground stably, lift the hand wheel to lock the anti slip, rotate the hand wheel until the hand wheel can be lifted and lowered without grinding (reserve a gap of 0
5 ~ 1mm); Then, tighten the fastening nut with a wrench and check whether there is no grinding jam when the hand wheel is lifted and lowered
Until the adjustment is appropriate (one adjustment can be used for a long time)
Installation on the track: hold the fixed side of the pressure divider with the left (or right) hand, open the movable side with the right (left) hand, put it into the rail head, and lift the hand wheel; Free up the left (or right) hand and tighten the change-over screw clockwise with your bare hands until the pressure block presses the rail surface and prevents it from falling off and clamping tightly, then you can loosen your hands
Then tighten the change-over screw with a torque wrench
