Problems solved by technology

[0002] In places where freight is concentrated such as ports, there are often steel pipes stacked in bulk that need to be hoisted, such as figure 1 As shown, when hoisting round rods such as steel pipes in a pile, the following two problems will be encountered: the first is the gathering problem caused by the shape, the circle is not easy to fix, and if it is bundled on site, it will seriously affect the lifting Efficiency, and once it is scattered during the lifting process, it will cause serious safety accidents; the second is the shaking and balance problems caused by the uncertain quantity. Usually the lifting quantity is certain, and it is easy to use such as figure 1 The traditional hangers shown are stacked and lifted, but the indeterminate quantity will cause insufficient adaptability. If it cannot be compacted, it will cause lifting shaking and affect the lifting balance

Embodiment 1

[0029] combined with Figure 2-3 Said port steel pipe stacking and handling crane stable lifting spreader includes a base plate 15 and a plurality of door frames fixed on the upper surface of the base plate 15 and arranged at intervals along the longitudinal direction of the base plate 15. The door frames are generally set to three , distributed at the two ends and the middle of the base plate 15; as required, the lower surface of the base plate 15 is longitudinally arranged with a plurality of reinforced channel steels 18, which can increase the bearing strength of the base plate 15, and can also facilitate forklift fork The door frame is composed of the flat frame plate 6 along the horizontal direction of the base plate 15 and the vertical frame plate 12 corresponding to the two plate surfaces to ensure the stability of the portal structure; as required, the two ends of the upper plate surface of the flat frame plate 6 Two lifting lugs 2 are fixed symmetrically for crane hoo...

Embodiment 2

[0035] The difference from Embodiment 1 is that the backing plate 16 is detachably installed on the upper surface of the base plate 15, the lower surface of the pressure plate 9 is provided with a T-shaped groove with a T-shaped cross-section and the end surface of the pressure plate, and the upper end of the suspender 10 The adapter is clamped in the T-shaped slot and can be moved and positioned in the T-shaped slot through the fastening bolt 22. When the diameter of the steel pipe changes, the steel pipe of the same specification can be adapted by replacing the crimping piece and the backing plate 16. However, due to the The width of the vertical frame plate 12 has been limited, and the thickness of the vertical frame plate 12 can be changed by installing a sub-plate on the inner surface of the vertical frame plate 12, thereby ensuring that the steel pipes close to the vertical frame plate 12 can be supported by resistance.

Abstract

A spreader for stable lifting of a port steel pipe stacking and handling crane, which relates to the technical field of lifting spreaders, includes a base plate and a plurality of door frames; the door frame is composed of a flat frame plate and two vertical frame plates, and the vertical frame plate There are strip holes on the surface of the plate, and the bottom of the flat frame plate is provided with a rotating rod, a pressure plate and a backing plate; two bearing seats are installed on the upper surface of the pressure plate, and the rotating rod is divided into two sections of unit rods, and two sections of unit rods The outer wall is respectively provided with two external threads with opposite directions of rotation, and the shafts of the two sections of unit rods are fitted with nut sets. The frame plate and the outer wall of the nut kit are correspondingly hinged; the pressure plate is evenly equipped with at least three crimping parts along the axial direction, the crimping parts include suspenders and inverted V-shaped pressure claws, and the surface of the backing plate corresponds to each inverted V-shaped pressure claw All are equipped with arc-shaped grooves; while the steel pipes are gathered and fixed tightly, the spreader can ensure that any number of steel pipes within the lifting limit can be compacted and lifted smoothly.

Description

technical field [0001] The invention relates to the technical field of hoisting spreaders, in particular to a spreader for stable lifting of a port steel pipe stacking and handling crane. Background technique [0002] In places where freight is concentrated such as ports, there are often steel pipes stacked in bulk that need to be hoisted, such as figure 1 As shown, when hoisting round rods such as steel pipes in a pile, the following two problems will be encountered: the first is the gathering problem caused by the shape, the circle is not easy to fix, and if it is bundled on site, it will seriously affect the lifting Efficiency, and once it is scattered during the lifting process, it will cause serious safety accidents; the second is the shaking and balance problems caused by the uncertain quantity.
