In the figure: 1. installing a base; 2. rotating the connecting rod; 3. holding the fixture tightly; 4. a safety connecting rod; 5. a soft block; 6. a rotating shaft; 7. positioning the shaft; 8. and rotating the shaft.
Detailed Description
The embodiment of the utility model provides a hold stone tongs assembly body tightly.
Referring to fig. 1, the method includes:
the mounting base 1 is installed, the top of the mounting base 1 is fixedly connected with an external hoisting mechanism, a rotating shaft 6 is fixedly connected to the front of the mounting base 1, two rotating connecting rods 2 are movably sleeved on the outer surface of the rotating shaft 6, the bottom ends of the rotating connecting rods 2 are respectively provided with a holding fixture 3, the two holding fixtures 3 are arranged in a tandem and crossed mode, the bottom ends of the holding fixtures 3 are arranged in an arc shape, the front sides of the rotating connecting rods 2 and the holding fixtures 3 are respectively provided with a safety connecting rod 4, and the mounting base 1, the two rotating connecting rods 2 and the two holding fixtures 3 are arranged;
at first, two 3 bottom segmental arcs of holding tool tightly move the both sides of the object of lifting by crane, when installation base 1 moves upwards, make the top of two rotating connecting rod 2 rotate for installation base 1, and then the top that has driven two holding tool 3 tightly rotates for two rotating connecting rod 2 respectively, thereby make two holding tool 3 alternately rotate, and then make the arc inner wall of holding tool 3 bottom closely laminate with the object surface of lifting by crane, thereby has played the fixed effect of effectual holding centre gripping tightly to the object of lifting by crane.
