Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.
By figure 1 to 3, the utility model discloses a vertical preformed hole 1 that runs through the beam slab, preformed hole 1 is located beam slab hoist and mount position, still include horizontally unable adjustment base 2, unable adjustment base 2 places on the beam slab, unable adjustment base 2 is last to install hoist engine and four foot rests 3, four foot rests 3 are located preformed hole 1 directly over, install a fixed pulley 4 that is located directly over preformed hole 1 on the four foot rests 3, preformed hole 1 below is equipped with a movable pulley 5, install lifting hook 6 on the movable pulley 5, still include wire rope 7, 7 one end of wire rope is fixed on movable pulley 5, the other end upwards passes preformed hole 1 and bypasses fixed pulley 4, pass preformed hole 1 downwards and bypass movable pulley 5, fix on the hoist engine at last, the hoist engine starts to drive movable pulley 5 and lifting hook 6 through wire rope 7 and rises or descends.
The four-foot stand 3 is provided with a horizontal transverse sleeve 8 and two vertical longitudinal sleeves 9 which are arranged at intervals from front to back, a steel wire rope 7 sequentially passes through the transverse sleeve 8 from the upper part and the two longitudinal sleeves 9 and then is fixed on a winch, and the three sleeves limit and guide the steel wire rope 7, so that the abrasion of the steel wire rope 7 is effectively avoided.
The fixed base 2 is a rectangular steel structure frame formed by welding I-shaped steel.
The winch comprises a motor 10 and a roller 11, a steel wire rope 7 is wound on the roller 11, the motor 10 drives the roller 11 to rotate through a transmission device, and the transmission device is a belt mechanism, a gear mechanism and the like.
The winch is detachably arranged on the fixed base 2 through bolts.
When the lifting device is used, the beam plate is lifted on the lifting hook 6, the motor 10 of the winch is started, and the winch drives the movable pulley 5 and the lifting hook 6 to ascend or descend through the steel wire rope 7, so that the beam plate is safely transported and placed.
The utility model has the advantages that:
