Detailed Description

To make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the embodiments of the present invention are combined to clearly and completely describe the technical solution in the embodiments of the present invention, and obviously, the described embodiments are some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1, the special fixture for hoisting the massive calcium carbide of the present embodiment has the following structure:

a pair of L-shaped clamping arms which are adjacent to each other front and back are arranged in a bilateral symmetry mode, the short arm sections 1 face downwards and are in a bilateral symmetry mode, the lower ends of the short arm sections are provided with arc claws 2, the upper end of the end face on one opposite side is provided with a limiting supporting block 3, the pair of arc claws 2 are oppositely arranged in a bilateral symmetry mode through concave surfaces, each arc claw 2 is horizontally arranged along the front direction and the back direction, the pair of L-shaped clamping arms are oppositely bent from the upper end of the short arm section 1 along the left direction and the right direction to form long arm sections 4, the pair of long arm sections 4 are hinged and connected through cylindrical pins 5 which are horizontally arranged along the front;

the top end of the long arm section 4 of each L-shaped clamping arm is sequentially provided with a first handrail 7, a triangular lifting lug 8 and a chain hook 9 at intervals from the tail end to the position between the hinged positions, the triangular lifting lugs 8 on the long arm sections 4 of the pair of L-shaped clamping arms are connected through two lifting chains 10 with equal length, one ends of the two lifting chains 10 are fixedly connected to the triangular lifting lugs 8 respectively, the other ends of the two lifting chains are fixedly connected through a triangular lifting ring 11, the size of the triangular lifting ring 11 is matched with that of a crane hook, and the chain hook 9 is inverted and can be hooked on a chain ring of the lifting chains 10;
