Drawings

Fig. 1 is the utility model discloses a change the structural schematic diagram of the unsettled drawing of patterns hoist of casting body acoustic baffle.

Detailed Description

The structure and the working principle of the suspended demoulding sling for the cast body sound absorption plate provided by the invention are further described in detail with reference to the attached drawings.

Refer to fig. 1, for the utility model provides a pouring body acoustic baffle unsettled drawing of patterns hoist's schematic structure. The structure that constitutes this unsettled drawing of patterns hoist includes the lifting hook, and it is by girder 11 and be located the long arm of force 12 and the short arm of force 13 at girder 11 both ends constitute, and the tip of long arm of force 12 and short arm of force 13 is fixed through jack catch 2 and acoustic baffle bead a 1's outside limit, acoustic baffle recess a 2's inside wall hook respectively, and the middle part of long arm of force 12 sets up rings 3, carries and draws rings 3, and the bottom surface a3 slope that the lifting hook will acoustic baffle a is unsettled.

The working principle is as follows: the lifting hooks of the lifting appliance are respectively arranged at two ends of a sound absorption plate a, a main beam 11 of the lifting hook is attached to the surface of the sound absorption plate a, a long force arm 12 claw 2 at one end of the main beam 11 is connected with the outer side edge of a convex rib a1 of the sound absorption plate, a short force arm 13 claw 2 at the other end of the main beam 11 is fixedly hooked with the inner side wall of a groove a2 of the sound absorption plate, a lifting ring 3 in the middle of the long force arm 12 is connected with a lifting rope of lifting equipment, the lifting ring 3 is lifted, the lifting hook obliquely suspends the bottom surface a3 of the sound absorption plate a, a worker can rapidly peel off a template attached to the bottom surface a 3.
