Therefore, the following detailed description and the accompanying drawings are merely illustrative of the technical aspects of the present invention, and should not be construed as limiting or restricting the technical aspects of the present invention.

As shown in fig. 1 to 2, a precast slab clamping hanger comprises a balance beam 1 and clamp devices 2 disposed at two ends of the balance beam 1, wherein each clamp device 2 comprises a first cross beam 3, a first clamping plate 4 is fixedly disposed at one end of the first cross beam 3, a second clamping plate 4 is disposed at the other end of the first cross beam 3, and the second clamping plate 4 is fixed on the first cross beam 3 by bolts, so that the second clamping plate can rotate around the fixed position thereof to a certain degree. A locking device is further disposed on the first beam 3 for limiting the pivoting of the second clamping plate 4.

A hook 7 is provided on the upper side of the first beam 3, and the first beam 3 is provided on both ends of the balance beam 1 by a rope passing through the hook 7. The symmetrical positions of the length direction of the balance beam 1 are also provided with lifting hooks 7, and the whole precast slab clamping lifting appliance can be lifted by penetrating ropes through the lifting hooks 7 and lifting the ropes.

A notch is formed in one end of the first cross beam 3 along the axial direction of the first cross beam, the second clamping plate 4 faces the first clamping plate 4 and is embedded into the notch and fixed through a pin shaft 5, and then the second clamping plate 4 can swing around the fixed position of the pin shaft 5. The second clamping plate 4 comprises a clamping jaw and a second cross beam 6 fixed with the clamping jaw, and the second cross beam 6 is matched with the notch and swings along with the clamping jaw in the notch.

The clamping jaw comprises a transverse plate 8 and a groove plate 9, the groove plate 9 is vertically fixed on one side of the transverse plate 8, a protruding structure adapting to a groove of the prefabricated plate is arranged on the groove plate 9, the protruding structure can be embedded into the groove of the prefabricated plate, the clamping jaw on the first clamping plate 4 is the same as the clamping jaw on the second clamping plate 4 in structure, and the prefabricated plate can be clamped by matching the first clamping plate 4 and the second clamping plate 4.

As shown in fig. 3 to 4, the locking device is disposed on the first beam 3 for limiting the counterclockwise movement of the second beam 6; the locking device comprises a limiting block 10 and a locking device 11, the limiting block 10 can be fixed on the first cross beam 3 through a bolt and can swing around the bolt, the fixing position of the limiting block 10 and the fixing position of the locking device 11 are distributed on two sides of the notch, the locking device 11 is composed of a bolt fixed on the first cross beam 3 in a rotating mode and a bending part on the upper portion of the bolt, the bending part can be buckled or separated from the limiting block 10, the limiting block 10 is switched between a locking state and an unlocking state, and therefore the limiting block is blocked on the notch, the second cross beam 6 is blocked, and swing of the second clamping plate 4 is limited.

The weight of one end of the second cross beam 6, provided with the lifting hook 7, is large enough, the clamp falls on a lifting object, the second cross beam 6 deflects downwards around the pin shaft 5 by means of the structure of the second cross beam 6, the limit block 10 limits the deflection of the second cross beam to be aligned with the first cross beam 3, the limit block 10 and the locking device 11 have the effects of limiting the downward deflection angle of the second cross beam 6, enabling the second cross beam to deflect to be aligned with the first cross beam 3, and then the deflection cannot be continued, the distance between the two clamping plates 4 at the bottom of the clamp is the largest, the clamp can be conveniently embedded into the prefabricated plate, the locking device 11 needs to be switched to the locking limit block 10 in advance during embedding, the second cross beam 6 cannot deflect upwards in the process that the lifting appliance is lifted by the crane, and the state that the distance between the two clamping plates 4 at the bottom of the clamp is the largest is always kept.

As shown in FIG. 5, which is a schematic diagram of the clamp falling on the precast slab, the locking state of the locking device 11 to the limiting block 10 is always maintained in the process of embedding the clamp into the precast slab, the second beam 6 is aligned with the first beam 3, the distance between the two clamping plates 4 at the lower part of the clamp is the largest, the lifting appliance is moved to the precast slab to be aligned with the precast slab, the positioning transverse plate 8 is dropped on the upper surface of the precast slab in the process of falling, the groove plate 9 is positioned at the side surface of the hung precast slab, and the shape of the groove plate 9 is matched with the contact part of the precast slab.

When the prefabricated slab is lifted, the locking device 11 needs to be unlocked, the locking of the limiting block 10 is released, and when the prefabricated slab is lifted, the lifting appliance drives the second cross beam 6 to deflect upwards in the lifting process, so that the clamping plate 4 on the second cross beam 6 is close to the lifted prefabricated slab, and the prefabricated slab is clamped and lifted.

After the prefabricated plate falls into the preset point, the lifting appliance descends, the second cross beam 6 deflects downwards to be aligned with the first cross beam 3, the clamping plate 4 can be far away from the lifted prefabricated plate in the process, the limiting block 10 is locked by the adjusting locking device 11, the prefabricated plate is prevented from being clamped by the clamp when the lifting appliance is removed, and therefore the lifting appliance is removed to lift the next prefabricated plate.

This prefabricated plate presss from both sides tight hoist, convenient to use, the hoist and mount in-process only need switch latch device 11 to stopper 10 the locking state can, simple structure, and save the manual work.
