Precast beam hoisting and fixing device

The utility model belongs to the field of precast beams, particularly relates to a precast beam hoisting and fixing device, and aims to solve the problems that an existing hoisting and fixing device is poor in structural flexibility, inconvenient to hoist precast beams of different sizes, poor in stability during hoisting and large in potential safety hazard. The lifting device comprises a lifting control plate, two movable adjusting plates, two telescopic control seats, two limiting seats and two limiting assemblies, two adjusting grooves are formed in the bottom of the lifting control plate, the movable adjusting plates are slidably installed in the corresponding adjusting grooves, fixing grooves are formed in the bottoms of the two movable adjusting plates, and the limiting assemblies are arranged in the fixing grooves. The telescopic control seats are slidably mounted in the corresponding fixing grooves, and hoisting hooks are fixedly mounted at the bottoms of the two telescopic control seats. The hoistin
