Automatic open and close multi-connected clamping device

Abstract

The invention discloses a multi-linked clamp which can be automatically opened and closed, comprising a clamp beam, two ends of which are pivotally connected with a pulling rod respectively; each pulling rod is pivotally connected with a turning arm, the other end of the turning arm is pivotally connected with a connecting rod mechanism installation frame and a clamping jaw simultaneously; the clamp beam is connected with a heavy connecting rod by a hinge; the hinge hole where the upper end of the heavy connecting rod is pivotally connected with the clamp beam is a long round hinge hole with the aperture more than that of a pin shaft; the lower end of the heavy connecting rod is pivotally connected with an automatic unhooking device which can rotate by 90 degrees automatically after being pressed; the connecting rod mechanism installation frame of the self-gravity clamp is provided with a groove which is matched with the automatic unhooking device; the automatic unhooking device and the groove which are connected on the clamp beam and the connecting rod mechanism installation frame and matched with each other can automatically control the opening and closing of the clamping jaw of the self-gravity clamp when supporting carbon blocks; and the long round hinge hole at the upper end of the heavy connecting rod can be wholly lifted up with the connecting rod mechanism installation frame and the automatic unhooking device, thus compensating the horizontal position error of the clamped carbon blocks.

Description

technical field [0001] The invention relates to an automatic opening and closing multi-connection clamp, which belongs to the technical field of carbon block clamping equipment in aluminum factories. Background technique [0002] At present, there are two main forms of multiple clamps used in the process of transporting anodes in the carbon block transfer warehouse in the electrolytic aluminum industry: pneumatic open and close multiple clamps and electric open and close multiple clamps. The opening and closing structure used in the pneumatic opening and closing multi-joint fixture has large dimensions and is not suitable for vertical stacking, which reduces the utilization rate of storage capacity. Electric opening and closing multiple clamps are suitable for vertical stacking, but the steel wire rope that controls the opening and closing of a single clamp is easy to elongate or break under the impact of lifting operations, and needs to be replaced frequently, the maintenan...

Problems solved by technology

Electric opening and closing multiple clamps are suitable for vertical stacking, but the steel wire rope that controls the opening and closing of a single clamp is easy to stretch or break under the impact of hoisting operations, and needs to be replaced frequently, the maintenance cycle is short, and the opening of the clamps is not easy to keep neat and consistent , affect the alignment, and at the same time, the existing electric open and close multi-joint fixture cannot compensate the height error of the upper surface of the carbon block and the interference between the connecting rod mechanism when clamping multiple carbon blocks at the same time, and the use effect is not very good.
