Lifting clamp for slope protection bricks

Abstract

The utility model discloses a hoisting fixture for slope protection bricks, which comprises a hoisting ring, the hoisting ring is sleeved with two steel wire hoisting ropes, the other ends of the steel wire hoisting ropes are connected with fixed pull rings, lever fixture components are arranged below the fixed pull rings, and the fixed pull rings are arranged at the two ends of the lever fixture components. The lever clamp assembly is composed of two lever pieces, the two lever pieces are directly and movably connected through a bearing, a movable clamping plate assembly is installed at the tail ends of the lever pieces, and an isolation plate assembly is arranged in the middle of the lever clamp assembly. When the slope protection bricks are insisted in the lever piece, the isolation plate assembly arranged in the lever clamp assembly enables the slope protection bricks which are in face-to-face contact originally to be isolated, and only one side (the face in contact with the lever piece) of each slope protection brick originally can enjoy upward friction force. When the isolation plate assembly is placed, the other side of the slope protection brick can receive upward friction force, and the situation that the slope protection brick falls off due to the fact that the self weight is too large and friction force is not enough is avoided.
