Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary tool equipment for steel structure production, in particular to a box beam turning hoist. Background Art

[0002] Nowadays, more and more large buildings are made of steel structures. Steel structure buildings are inseparable from large box beams and box column components. Such box beam and column components are usually several meters or even dozens of meters long. When steel structure factories make large box beams and steel columns, they often make the components around them in the workshop before installing them. When the box beams and columns are undergoing process processing at different parts, they need to be turned over. Since the box beams and columns themselves are heavy and have a large volume, the turning operation is very troublesome. It requires multiple people to operate with the help of large lifting equipment and lifting wire ropes, which is time-consuming. Therefore, it is necessary to design a relatively convenient turning operation tool. Utility Model Content

Detailed Description of the Preferred Embodiment

[0015] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the drawings of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. In the description of the present utility model, it should be noted that the terms "upper", "lower", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship when the product of the present utility model is normally placed. It is only for the convenience of describing the present utility model or simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed or operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0016] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0017] See also Figures 1 to 3 The utility model is a box beam turning hoist, including a left hook 9 and a right hook 11. The upper parts of the left hook and the right hook are connected together through a longitudinal axis 10 and can be rotated to the left and right sides and separated. A lifting ring 1 is also arranged on the longitudinal axis between the left hook and the right hook. The lifting ring is used for hooking the box beam column 12 workpiece during the turning operation; further, the lower part of the lifting ring in the utility model is welded and fixed on the longitudinal axis and separates the left hook from the right hook by a certain distance.

[0018] Furthermore, the left hook and the right hook described in this embodiment are both L-shaped structures, and each L-shaped structure is composed of a vertical rod 3 and a horizontal plate 4. The horizontal plate is fixed to the lower end of the corresponding vertical rod, and the longitudinal axis is connected to the upper part of the two vertical rods. The two horizontal plates are arranged in opposite directions. Further, the two horizontal plates described in the utility model are provided with anti-slip stripes 5. Further, one end of the longitudinal axis described in the utility model has a bolt cap 2, and the other end of the longitudinal axis is provided with a section of thread 7. The longitudinal axis connects the left hook and the right hook, and the threaded part is equipped with a locking nut 8. The bolt cap and the locking nut sandwich the left hook and the right hook in the middle; the threaded part is also provided with a latch hole and a latch 6, and the latch hole and the latch are placed outside the locking nut and limit the locking nut.

[0019] See attached Figure 4 In actual use, the left and right hook ends are locked with locking nuts so that the left and right hooks cannot fall off the longitudinal axis. When turning over the box beam column, the box beam column is usually placed on the tire frame. When lifting with a crane, first hook the left hook to the left corner edge above the box beam column (see figure), and then hook the right hook to the lower corner edge of the right side of the box beam column. When lifting, hang the hook of the hoisting wire rope on the lifting ring, and slowly move the crane forward, and the box beam column will slowly turn over to the left hook direction, which is safe and labor-saving.

[0020] In the above process, Figure 4As can be seen from the schematic diagram, during the upward hanging process, at the beginning, the entire lifting center is at the right-biased position. When slowly rising, it is very easy to make it turn over by using the self-gravity of the box-shaped beam-column. On the contrary, if you want the box-shaped beam-column to turn over to the right, you only need to swap the positions of the left and right hooks and then hook them up to achieve it, which is very easy and labor-saving, and has high safety.

[0021] The structure of the utility model is simply designed, and the hooking is convenient and fast. It is very efficient to cooperate with the lifting equipment to turn over the box girder. The entire lifting tool can adaptively hook the box-shaped beam-columns within a certain size range, with strong flexibility, obvious actual effect, and has good popularization and application value.
