(see FIG. 1 and FIG. 2)

Wherein, the length and width of the section of the gate post 1 are 200mm and 200mm, and the length is 1000 mm; the length and width of the section of the door beam 2 are 200mm and 200mm, and the length is 1000mm and 3000 mm; the diameter of the fixed pulley 3 is 200 mm; the hanging lug 4 is processed by a thick steel plate with the thickness of 14mm, the length and the width of the hanging lug are 100 x 100mm, a hoisting hole with the diameter of 20mm is arranged in the middle, and the diameter of the movable pulley 5 is 300 mm; the length and width of the cross section of the inclined strut 6 are 200mm and 200mm, the length is 500mm, and an included angle between the inclined strut 6 and the horizontal plane is 45 degrees; the lifting rope 7 is formed by processing a steel wire rope with the diameter of 10mm and has the length of 30000 mm; the pull rope 8 is formed by processing a steel wire rope with the diameter of 10mm and has the length of 10000 mm.

During the use, with two gateposts 1 of hoist and mount combined bay welded fastening respectively on two girder steels 9 that the frame is adjacent, then release stay cord 8, make lifting rope 7 transfer to subaerial small-size component 10 position, small-size components 10 such as vaulting pole, pull rod are bound to the lifting rope, later stimulate stay cord 8, and small-size component 10 is mentioned to lifting rope 7, and up to the mounting height, constructor can install small-size component 10. Due to the use of the movable pulley 5, the pulling force of an operator is larger than half of the weight of the small component 10, and the operation is very convenient and labor-saving (fig. 3 and 4).

The hoisting combined frame is simple to assemble and convenient to operate, avoids the use of a large number of cranes, is convenient and quick, saves time and labor, and greatly reduces the construction cost.

In the figure, a door post 1, a door beam 2, a fixed pulley 3, a hanging lug 4, a movable pulley 5, an inclined strut 6, a lifting rope 7, a pull rope 8, a steel beam 9 and a small component 10.

Detailed Description

Fig. 1-4 illustrate an embodiment of the present invention. The utility model is further described below with reference to the accompanying drawings.

The hoisting combined frame comprises a door post 1, a door beam 2, a fixed pulley 3, a suspension loop 4, a movable pulley 5, an inclined strut 6, a lifting rope 7 and a pull rope 8; are used in combination. With door beam 2 welded fastening on the top of two gateposts 1, two bracing 6 of both sides welding below every gatepost 1, with fixed pulley 3 and hangers 4 all welded fastening in door beam 2 bottom surfaces, fixed pulley 3 and hangers 4 interval 300mm, with 8 one end of stay cord and hangers 4 fixed, the other end passes a diameter 300 mm's movable pulley 5, then passes fixed pulley 3 temporary fixation again, 7 one end of lifting rope and 5 bottom mounting of movable pulley, the other end freely hangs down.

During the use, with two gateposts 1 of hoist and mount combined bay welded fastening respectively on two girder steels 9 that the frame is adjacent, then release stay cord 8, make lifting rope 7 transfer to subaerial small-size component 10 position, small-size components 10 such as vaulting pole, pull rod are bound to the lifting rope, later stimulate stay cord 8, and small-size component 10 is mentioned to lifting rope 7, and up to the mounting height, constructor can install small-size component 10.
