Detailed Description
As shown in fig. 2, the present utility model includes a hanger and a boom; the hanger comprises two longitudinal rods 1 which are arranged in parallel and have a certain interval, a lower cross rod 2 is welded between the lower ends of the two longitudinal rods 1, a plurality of main rib limiting pipes 3 are longitudinally welded on the top surface of the lower cross rod along the lower cross rod, the axial direction of each main rib limiting pipe 3 is parallel to the longitudinal rods 1, an upper cross rod 4 is welded between the upper ends of the two longitudinal rods 1, a plurality of main rib limiting grooves 5 are formed in one side of each upper cross rod 4, and the main rib limiting grooves 5 correspond to the main rib limiting pipes 3 one by one; the lifting rod 6 is parallel to the upper cross rod 4 of the lifting frame, lifting lugs 7 are respectively arranged on top surfaces of two ends of the lifting rod 6, the upper ends of the two longitudinal rods 1 are respectively connected with bottoms of two ends of the lifting rod 6, a second lifting rope 9 is respectively connected with bottoms of two ends of the lifting rod 6 in the middle of the two longitudinal rods 1, and the length of the second lifting rope is smaller than that of the first lifting rope plus that of the middle of the longitudinal rod to the upper end of the longitudinal rod.
According to the structure, the hanging rods are horizontally lifted by the hanging machine through the hanging lugs on the top surfaces at the two ends of the hanging rods, and when the hanging rods are lifted away from the ground, the hanging rods form a certain inclination angle with the horizontal surface; the inclination angle of the hanger can be adjusted by adjusting the length of the second hanger rope, so that the inclination angle of the hanger can be made consistent with the inclination angle of the tower by adjusting the length of the second hanger rope 9 according to the inclination angle of the tower.
As shown in fig. 3, in the implementation of the present utility model, the main rib limiting pipe 3 may be a section of steel pipe with a diameter larger than that of the main rib of the tower, and the lower end of each steel pipe is welded to the top surface of the bottom cross bar 2.
As shown in fig. 4, in the implementation of the present utility model, a limiting plate 10 may be welded to the bottom of the upper rail 4 in the longitudinal direction, one side of the limiting plate 10 protrudes to a certain width outside the upper rail 4 in the direction perpendicular to the longitudinal direction of the vertical rod 1, and the main rib limiting groove 5 is formed on one side of the limiting plate 10 protruding to the outside of the upper rail 4.
Further, in order to prevent the main rib from separating from the main rib limiting grooves, two sides of each main rib limiting groove 5 on the limiting plate 10 may be respectively provided with an insertion hole, and a U-shaped limiting rib 11 is inserted into the insertion hole at two sides of each main rib limiting groove 5; the opening of the U-shaped limiting rib 11 faces downwards, and two ends of the U-shaped limiting rib are respectively inserted into insertion holes on two sides of the main rib limiting groove.
