For achieving the above object, the technical solution of the utility model is,

The bearing stone tongs comprises, the cantilever framework, and two hold-down arms, link joint is in cantilever framework two ends respectively; It is a hollow structure; Four outer claw type hooks are fixed in described two hold-down arm lower ends respectively in twos; Four interior claw type hooks, the corresponding respectively back side of being fixed in described four outer claw type hooks; Regulating mechanism comprises, kink ring, kink nut, adjusting screw(rod), rocking arm; Wherein, the kink ring is embedded and is fixed in the hold-down arm hollow structure; The kink nut is embedded and is fixed in another hold-down arm hollow structure; Adjusting screw(rod) one end wears kink nut and kink ring, and rocking arm is fixed in the adjusting screw(rod) other end.

Again, the utility model also comprises two locating pieces, and two hole slots are offered in this locating piece bottom, and described four outer claw type hooks are fixed in two hole slots of these two locating piece bottoms respectively in twos, locating piece top is embedded at two hold-down arm bottoms respectively, and is fixed by bolted connection.

Again, the hole slot screw thread fit of four outer claw type hooks described in the utility model and locating piece bottom connects, and can adjust inside and outside claw type hook, work contact surface the relative position error to minimum rating.

Be connected and fixed with strut between described two adjacent outer claw type hooks.

Described four outer claw type hooks two twenty percent A fonts respectively are fixed in described two hold-down arms or two locating piece lower ends.

The utility model cooperates by kink ring, kink nut, adjusting screw(rod), the rocking arm of regulating mechanism, under the gyroscopic action of adjusting screw(rod), be assemblied in inside and outside claw type hook on the hold-down arm, have the activity regulatory function of telescoping, realize effect different bearing size clamping range and application force; And, realize integral hoisting by inside and outside claw type hook realization inboard or outer lateral section clamping to bearing.

In advance stone tongs is located on the hoist cable of weight-lifting equipment, drive the adjusting screw(rod) revolution of being located on the stone tongs between the supported on both sides arm by hand arm, under transmission of kink nut and kink ring restriction, the conduction by pitch and spiral power, impel its inside and outside claw type hook that is fixed on hold-down arm one end, the pin type bolt that is arranged on the suspended wall framework with the movable end of hold-down arm is the axle center revolution; Realize the inside withdrawal of the inside and outside claw type hook in both sides or outwards expand the synchronous shift operating state.

The hanging clamp prodigiosin is by bearing inboard or lateral surface, make inside and outside claw type hook work contact surface exceed bearing one side end face, hand again revolution adjusting screw(rod) by the transfer function of pitch and spiral power, is realized inboard or the technology clamping of outer lateral section and the lifting to bearing of the inside and outside claw type hook of stone tongs.

The beneficial effects of the utility model

The utility model has been realized the overturn technical innovation of every row bearing and wire rope handling rope technology lifting operating mode of traditional manpower has greatly been alleviated manual operation intensity, has improved the work efficiency of bearing clean and maintenance.
