It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.
[0027] In this utility model, unless otherwise stated, directional terms such as "up, down, left, right, front, back, inside, outside" in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as a limitation on the term.
[0028] See Figure 1-4 The pipe lifting device shown includes a lower crossbeam 1 and an upper crossbeam 2 disposed above the lower crossbeam 1. Slider blocks 14 are slidably disposed at both ends of the lower crossbeam 1. The two ends of the upper crossbeam 2 are hinged to the sliders 14 via swing arms 8. The bottom of the sliders 14 extends to the bottom of the lower crossbeam 1 and is connected to a longitudinal beam 17. Multiple hooks are disposed on the longitudinal beam 17. At least two limiting rods 13 are symmetrically disposed at the bottom of the lower crossbeam 1 between the two longitudinal beams 17. A suspension structure is connected to the upper crossbeam 2. At least two guide rods 3 are symmetrically disposed on the lower crossbeam 1 and slide through the upper crossbeam 2.
[0029] By implementing the above technical solution, during use, an overhead crane or other equipment is used to lift the pipe fittings to the pipe stacking area using the suspension structure. Then, the limiting rod 13 is placed on multiple pipe fittings. At this time, the upper crossbeam 2 falls along the guide rod 3 due to its own weight, pushing the sliders 14 at both ends to slide outward, causing the longitudinal beam 17 to slide outward, so that multiple hooks are in the open state. During lifting, the suspension structure pulls the upper crossbeam 2 upward, and the swing arms 8 at both ends pull the sliders 14 to move multiple hooks inward and hook them into the pipe fittings. As the hooks continue to rise, multiple pipe fittings are lifted. This pipe fitting lifting device can simultaneously lift multiple pipe fittings arranged in a row, with high efficiency.
[0030] In this embodiment, the lower crossbeam 1 has sliding holes at both ends for the slider 14 to slide through, and guide holes 16 are provided on both sides of the sliding holes; shafts 15 are inserted through both ends of the slider 14, and the two ends of the shafts 15 slide within the guide holes 16, with bushings 26 fitted at the ends of the shafts 15; the lower end of the swing arm 8 extends into the sliding hole and is rotatably fitted onto the shaft 15.

The ear plate 19 is provided with a screw hole, and a fastening screw 20 is installed in the screw hole. The fastening screw 20 passes through the screw hole and is pressed and fixed to the side of the longitudinal beam 17. The first hook body 21 and the second hook body 23 are both arranged inward. Multiple first hook bodies 21 at the same end are aligned, and multiple second hook bodies 23 at the same end are also aligned. After the second hook plate 18 is moved, the ear plate 19 is fastened to the side of the longitudinal beam 17 by the fastening screw 20. Multiple ear plates 19 and corresponding fastening screws 20 can be provided.
[0035] In this embodiment, studs 12 are symmetrically arranged on the limiting rod 13, and vertical rods 9 are arranged on both sides of the lower crossbeam 1.
