The specific embodiment

The explanation of mark among the figure: 1-bearing, 2-first bearing pin, 3-gland, 4-screw rod, 5-spring, 6-lever, 7-adapter sleeve, 8-chain, 9-shackle, 10-fork, 11-counterweight, 12-steel pipe socket, 13-second bearing pin, 14-nut, 15-packing ring, 16-split pin.

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Referring to Fig. 2, Fig. 3 and Fig. 4.The utility model embodiment's Conticaster swing type strand baffle plate,Comprise baffle plate, bearing, revoliving arm, it is characterized in that: described baffle plate is the individual swing component that flexibly connects with bearing 1 pivot pin, and lever 6 one ends are placed baffle plate, and the other end is placed a counterweight 11, and baffle plate is connected (Fig. 2) through chain 8, fork 10 with revoliving arm.

Described baffle plate is an elastic baffle assembly, comprises gland 3, screw rod 4, spring 5 and steel pipe socket 12, and gland 3 utilizes nut 14, packing ring 15, split pin 16 to be connected with steel pipe socket 12 through screw rod 4, and gland 3 is fixed with screw rod 4; Spring 5 is housed in the cavity of gland 3, and spring 5 is enclosed within on the screw rod 4, can move axially along screw rod 4; Adapter sleeve 7 is connected (Fig. 3) through chain 8 with fork 10.

Lever 6 is connected with bearing 1 through first bearing pin 2, can be around 2 rotations (Fig. 3) of first bearing pin.Lever 6 one ends are elastic baffle assemblies, and lever 6 other ends are counterweight 11, and are all fixed with lever 6; Gland 3 utilizes nut 14, packing ring 15, split pin 16 to be connected with steel pipe socket 12 through screw rod 4, and gland 3 is fixed with screw rod 4; Spring 5 is housed in the cavity of gland 3, and spring 5 is enclosed within on the screw rod 4, can move axially along screw rod 4.The connection aperture of being opened on the invar pipe box 12 is bigger and littler than the external diameter of packing ring 15 than screw rod 4 external diameters; So gland 3, when spring 5 installs; Gland 3, screw rod 4 move axially along steel pipe socket 12 can only compress spring 5, and its effect is the bump through spring 5 buffering strands; Adapter sleeve 7 utilizes bolt to be connected with steel pipe socket 12; Chain 8 is connected with adapter sleeve 7 and fork 10 respectively through shackle 9.
