Abstract
The utility model discloses a counter weight baseplate and a hinge pin inserting-pulling mechanism thereof. Lug hinge supports (1, 2, 3 and 4) are arranged on the top surface of the counter weight baseplate (100) and used for connecting the counter weight baseplate (100) to a rotary table (200). The hinge pin inserting-pulling mechanism comprises hinge pins (5 and 13), connecting rods (7 and 11) and a rocker rod (9) which are movably hinged in sequence, wherein the hinge pins are aligned with the lug hinge holes of the lug hinge supports; the rocker rod is fixedly hinged to the fixed hinge point (J0) of the counter weight baseplate, so that the rocker rod can be rocked around the fixed hinge point to drive the connecting rods to insert or pull the hinge pins. On the counter weight baseplate on which the hinge pin inserting-pulling mechanism is mounted, the rocker rod can be rocked around the fixed hinge point to drive the connecting rods to move so as to drive the hinge pins to be inserted into or pulled out of the lug hinge holes of the lug hinge supports. Thus, the hinge pins can be inserted or pulled conveniently so as to mount the counter weight baseplate to the rotary table or dismount the counter weight baseplate from the rotary table, and the problem that inserting or pulling hinge pins is difficult due to narrow space between the lower part of the rotary table and the conventional counter weight baseplate is solved.
