Running Sport Hats Use a wide range

Rail accessory is used in a wide range of rail support is also a rail accessory, rail support is a rail accessory in order to effectively anti-wheel-rail transverse force, installed in the rail outside the components. The classification of the rails can be divided into the following three categories.

  1) anti-climbing rail support: including the basic rail, pad, fork pillow bolt, fork pillow, the basic rail body along the long distance with holes, anti-climbing rails through bolts, loose nuts connected to the basic rail, The two sides of the rails are jammed on both sides of the pad, and the pad is connected to the fork through the fork bolt. This rail support can not only effectively limit the longitudinal position of the basic rail, prevent the basic rail, the relative displacement of the fork, but also to ensure the stability of the switch structure and turnout high ride comfort.

  2) Adjustable rail support: This rail accessory adjustable rail support by the adjustable rail body, adjustable rail support rack base, rail washers and nylon rail base cushion, which is characterized by: adjustable rail support Rack base of the rack slope of 12 ° ~ 15 °, the tooth pitch of 10-15mm,

  3) Elastic rail support: the design of the rail is mainly set in the turnout switch basic rail, guide rails and rails and other non-working side of the side, double-turn the double turnout of the basic track is also set rail support. Turnout set in the rails is mainly to prevent the rail overturning and gauge expansion, to ensure the stability of the rail. In the rails in the track plate also plays an important role in today's rail parts manufacturers for everyone to tell us in detail.

    The track pad is used for matting under the track and is arranged along the full length of the track. The width is 4-5mm smaller than the width of the rail. Composite pad structure into a two-layer rubber embedded 0.5-0.7 high-quality steel plate through the composition of hot plastic composite structure type. Composite plate temperature range of -20 ? -80 ?.

    The surface of the track plate is distributed in the longitudinal direction of the groove, the width of the groove is 3mm, installed in the track below the installation, after the installation of the rail plate through the pre-pressing force, so that the track pad and track and track bottom to keep in close contact, To compensate for the unevenness of the track bearing surface, in the load when the plate under the action of the wheel will not be elongated, but the groove is compressed to fill, enhance the track plate stiffness, but also to prevent the track under high wheel pressure Resulting in excessive internal stress, uniformed the crane wheel pressure, eliminating the concentrated load generated by the fatigue stress.

    In the track plate embedded in the reinforced steel plate, which makes the track plate has a high lateral stiffness, even under great pressure, the track pad surface oil friction decreased, then there will not happen rail pad Plate shift, reducing the wear of the track pad. With the above-mentioned adjustable combination rail plate and track plate, the vibration buffer performance greatly improved, significantly reduce the crane running vibration and noise, is conducive to the mechanical parts of the crane, electrical work and improve the service life.
