Detailed Description

Referring to fig. 1-3, the embodiment is a steel ingot clamp with a self-locking mechanism, including two clamp arms 1 which are arranged in a crossed manner, the middle parts of the two clamp arms 1 are rotationally connected through a pin shaft, the bottom ends of the clamp arms 1 are provided with clamping parts 7, the top ends of the two clamp arms 1 are respectively provided with a connecting rod 2, the top ends of the two connecting rods 2 are jointly connected to a connecting block 3, the lower ends of the connecting blocks 3 are rotationally connected with the connecting rods 2, lifting holes are formed in the upper ends of the connecting blocks 3, the lower ends of the clamp arms 1 are provided with guide inclined blocks 6, an installation cavity is formed below the guide inclined blocks 6, a limiting surface 9 is formed on the top surface of the installation cavity, two support plates are installed in the installation cavity, a wedge block 8 is rotationally connected between the two support plates, the upper ends of the other clamp arms 1 are correspondingly provided with a suspension rod 4, the top ends of the suspension rod 4 are rotationally connected with the clamp arms 1, a hook 5 is arranged at the bottom of the suspension rod 4, and the hook 5 faces the direction of the wedge block 8.

Further, an anti-slip pad is installed on one surface of the clamping part 7 facing the clamped object.

Further, the wedge block 8 is heart-shaped.

Further, the clamping arm 1 comprises two clamping plates, a connecting shaft is arranged at the upper end between the two clamping plates, the suspension rod 4 is arranged in the middle of the connecting shaft, and the top end of the suspension rod 4 is rotatably connected with the connecting shaft. Referring to fig. 4-7, the method of use of the present utility model is as follows: when the clamping object is released from the clamping state, the whole clamp is put down by the lifting device, after the clamping object is placed on the ground, the two clamping arms 1 are opened under the action of self gravity, the heights of the upper ends of the two clamping arms 1 are continuously lowered, the hook 5 at the bottom of the hanging rod 4 also slides downwards along the guide inclined block 6, when the hook 5 moves to the limiting surface 9, the lifting device stops descending, the hook 5 is naturally hung at the limiting surface 9, the two clamping arms 1 are connected and fixed under the action of the hook 5, and then the lifting device moves upwards with the clamp, so that the clamp can be hung to other places for use; the switching from the opening state of the clamping arms 1 to clamping the clamped object is carried out, the lifting devices continue to move downwards, so that the two clamping arms 1 continue to open, meanwhile, the hooks 5 descend by a certain height, when the hooks 5 are lower than the inclined blocks, the lifting devices move upwards again to drive the hooks 5 to move upwards, the inclined blocks are hooked by the hooks 5 to enable the inclined blocks to turn upwards, when the wedge blocks 8 contact the guide inclined blocks 6, the hooks 5 cannot be hung into the limiting surfaces 9 due to the blocking of the wedge blocks 8, the lifting devices continue to move upwards with the hooks 5, the hooks 5 move upwards along the guide inclined blocks 6, and at the moment, the lifting devices continue to move upwards with the clamping arms 1 to clamp the clamped object.
