Picture peg friction introduction mechanism

The utility model discloses a picture peg friction introduction mechanism, including box and hydraulic motor, compression spring, friction pulley pedestal and driving gear are installed to the box, the box passes through compression spring and connects the friction pulley pedestal, install a set of or two sets of friction pulleys on the friction pulley pedestal, hydraulic motor drive driving gear, driving gear drive a set of or two sets of friction pulley syntropys are rotated. Use the utility model discloses a length that highly is less than the picture peg of the picture peg frame body alleviates support body weight, the less excavator of the supporting model of only need, reduction equipment and construction cost, the utility model relates to an initiative picture peg mechanism, solve chain specification or wire rope's diameter is great and length is longer, technological problem such as installation, maintenance difficulty, simultaneously thoroughly the chain rupture of solve tradition picture peg mechanism restrict and trouble problems such as drive sprocket, wire rope job -hopping are deviate from to the chain absolutely. The utility model relates to a during picture peg friction introduction mechanism is applied to weak soil construction trade of excellent performance.
