a lifting appliance of a hinge type precast block comprises a hanging scaffold and a scissor type clamp; the hanging scaffold is a square metal frame, and a hanging ring A is arranged at the center of the top of the hanging scaffold and used for connecting a hook of a crane; four hanging rings B are arranged at four corners of the bottom of the hanging scaffold, and each hanging ring B is connected with two steel wire ropes; two steel wire ropes connected with each hanging ring B are connected with the scissor-type clamp; the scissors type clamp is composed of a bent clamping piece A and a bent clamping piece B as well as a clamping rod A and a clamping rod B which are obliquely welded at the lower ends of the clamping piece A and the clamping piece B respectively; the clamping piece A and the clamping piece B are rotatably connected through a bolt; two steel wire ropes connected with each hanging ring B are respectively connected with the upper ends of the clamping pieces A and the clamping pieces B.

Preferably, the hanging scaffold is a 96 × 96cm square metal frame.

Preferably, the periphery of the hanging scaffold is enclosed by square steel in a welding mode, the middle of the hanging scaffold is in a cross lapping mode through angle steel to form a structure shaped like a Chinese character 'mi', and the middle structural material is formed by welding the angle steel.

Preferably, the clamping rod A and the clamping rod B are screws with external threads on the surfaces.

Compared with the prior art, the utility model discloses following beneficial effect has:

1. adopt this hoist at the effectual swing of the unsettled in-process of prefabricated section of control of hoist prefabricated section in-process, reduced the friction and collision between the prefabricated section, reduced the damaged phenomenon of prefabricated section, protected the integrality of finished product prefabricated section, practiced thrift the cost.

2. In the construction operation environment specified by the safe operation specification of hoisting equipment (wind power is less than or equal to 5 grades), due to the action of the scissor clamp, the swinging of the precast block in the air is reduced, the lifting hook is reduced, the precast block can be accurately hoisted to an expected position, and constructors only need to put the precast block in sequence, so that the laying speed of the precast block is greatly increased, the construction progress is ensured, and the potential safety hazard is reduced.

3. The novel hoisting tool is adopted, the configuration of constructors is reduced, the prefabricated block can be placed into the hoisting tool only by 1 person at the hoisting end of the fixture, and the prefabricated block can be placed into the specified position only by 2-3 persons at the unloading end, so that the operation is simple and labor-saving, and the configuration of the constructors is optimized.
