Gantry crane rail clamp configuration and design features

        Electric  hoist gantry crane  rail clamp and the locomotive is a hole through the rear axle clamp connection, locomotives when walking, dragging (push) synchronous dynamic rail clamp is moved, the guide rail clamp wheel in under the pressure of the weight along the Snake rail rolling, and by guiding wheel bracket, drive shaft guide rail clamp pliers whole surface of the fixed shaft floating along the track, so the rail clamp pliers with the centerline of the track rail clamp pliers and the lowest point of the height of the track surface is always controlled at design value, the walking track rail clamp will not produce grazing clamp, clamp the mouth so that the two are consistent clamping force.
         The device is in its lower jaw iron designed a hook, this hook rail clamp clamp tight in the rail after rail can be fastened to prevent electric hoist  overhead gantry crane  rail clamp pliers slide along its own accident while on the move The clamping force is released.
      (A) technical parameters for each sub-clamp clamping force 20t; jaw opening 20 °; open clamp time 7s; clamp time 10s; open caliper clamp rail surface distance from the lowest point of 30mm; windproof level 12.
      (2) electric hoist gantry crane rail clamp design features:
      ① electric hoist  bridge gantry crane  rail clamp locking clamping mechanism is designed after clamping point C below the AB connection, so that the clamping force from other factors, to keep within the design value; ② compressible reservoir can be set within the accumulator spring rod, connecting rod can be shortened with the compression of the spring, to meet the dead point over the technical conditions required for the design, but also has a compensation function; ③ installed on a four door rail clamp, total clamping force up to 80t, can withstand 12 gale; simultaneously clamp hook head design, can prevent vehicle rollover; ④ rail clamp rises up after opening pliers 100mm, making it the lowest point to keep away from the rail surface distance 30mm, locomotives and rail clamps when walking interference will not occur; ⑤ guide rail clamp wheel overcome flatness and straightness of rail defects, rail clamp so that the center line of the center line of the track surface and the height of the jaw and the rail maintained within the design value.
