Detailed Description

The embodiment of the utility model provides an adjustable hoisting tool for hoisting large-section H-shaped steel, which is described below with reference to the attached drawings.

As shown in fig. 1 and 2: the lifting device of this embodiment includes: the first body 1, the second body 2, the first lug plate 3, the second lug plate 4 and the bolt 5. Before the hoisting construction, the hoisting tool of the embodiment is divided into four independent hoisting tool parts, is simple to disassemble and can be repeatedly used, and can be flexibly installed according to the position of the hoisted H-shaped steel beam. The first body 1 and the second body 2 are L-shaped, and the overlapped part in the horizontal direction passes through the first body 1 and the second body 2 through the bolt 5 to be detachably connected. The fixed end of the first body 1 is provided with through holes I6 arranged at intervals, the fixed end of the second body 2 is provided with through grooves I7, and the clamping length in the horizontal direction can be adjusted by changing the relative positions of the through holes I6 and the through grooves I7 when the bolt is used for fixing. Two ends of the first body 1 and the second body 2 are downwards formed into concave structures, and through grooves 8 are formed in opposite positions of extending parts at the two ends. First otic placode 3 is L shape with second otic placode 4, and wherein vertical one end is equipped with two 9 through-holes that the interval set up, uses the block length of the adjustable vertical direction of relative position through changing two 9 through-holes and leading to two 8 through the groove when the bolt fastening. The horizontal ends of the first lug plate 3 and the second lug plate 4 are arranged oppositely, a gap is reserved between the first lug plate and the second lug plate, a T-shaped cavity with an open lower end is formed between the first lug plate and the two bodies, and the cavity is matched with one end of the section of the H-shaped steel beam to be lifted in shape. The fastening capacity of the lifting appliance can be enhanced, and the lifting safety is improved.

The lifting device of this embodiment includes: the first body 1, the second body 2, the first lug plate 3, the second lug plate 4 and the bolt 5. Wherein the first body 1 and the second body 2 can be fan-shaped, and the circle center end is provided with a rectangular notch. The connection can be dismantled through bolt 5 passing first body 1 and second body 2 to the horizontal direction coincidence part, and 1 stiff end of first body is equipped with through-hole 6 that the interval set up, and 2 stiff ends of second body are equipped with logical groove 7. When the bolt is used for fixing, the clamping length in the horizontal direction can be adjusted by changing the relative positions of the first through hole 6 and the first through groove 7. The rectangular gaps of the first body 1 and the second body 2 are oppositely arranged to form a concave structure. The two through grooves 8 are formed in the opposite positions of the extending parts at the two ends of the first body 1 and the second body 2. First otic placode 3 and second otic placode 4 also can be for fan-shaped, and the centre of a circle end is equipped with the rectangle breach, and wherein vertical one end is equipped with two 9 through-holes that the interval set up, and the block length of the adjustable vertical direction of relative position through changing two 9 through-holes and leading to two 8 groove when using the bolt fastening.
