[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] The purpose of this utility model is to provide a multifunctional and easily disassembled spreader pole to solve the problems existing in the prior art, which can be applied to the hoisting of different components and has a more flexible usage method.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] like Figures 1-3 As shown, this embodiment provides a multifunctional and easily detachable spreader beam, including an upper spreader beam 1 and a lower spreader beam 2. The upper end of the upper spreader beam 1 is provided with a crane connection structure 101, through which the upper spreader beam 1 is connected to a crane. The lower end of the upper spreader beam 1 is provided with at least one upper spreader beam hoisting connection structure 102, which can be used for hoisting components and for connecting with the lower spreader beam 2. The upper end of the lower spreader beam 2 is provided with a lower spreader beam connection structure 201, and the lower spreader beam connection structure 201 and the upper spreader beam hoisting connection structure 102 can be detachably connected. The lower flat beam 2 is equipped with a lower flat beam hoisting structure 202. Both the upper flat beam hoisting connection structure 102 and the lower flat beam hoisting structure 202 can be used to hoist components. Generally, the upper flat beam hoisting connection structure 102 or the lower flat beam hoisting structure 202 is used for hoisting, rather than the upper flat beam hoisting connection structure 102 and the lower flat beam hoisting structure 202 being used for hoisting work at the same time.

[0028] In practical use, only the upper flat beam 1 can be used for hoisting. The upper flat beam 1 is directly connected to the crane or indirectly through other connecting parts, and the crane moves the upper flat beam 1. The lower end of the upper flat beam 1 is used to hoist components through the upper flat beam hoisting connection structure 102. If some components are not suitable for hoisting using the upper flat beam hoisting connection structure 102, a lower flat beam 2 can be installed at the lower end of the upper flat beam 1. That is, the lower flat beam connection structure 201 and the upper flat beam hoisting connection structure 102 are connected, and then the components are hoisted using the lower flat beam hoisting structure 202 on the lower flat beam 2 through hoisting ropes.

[0029] In this embodiment, the crane connection structure 101, the upper spreader beam hoisting connection structure 102, and the lower spreader beam connection structure 201 can all be existing lifting lug assemblies. Each lifting lug assembly includes two parallel lifting lug plates, and each lifting lug plate has a lifting lug connection hole. For example... Figure 1 As shown, the axial direction of the lifting lug connection hole in the crane connection structure 101 is perpendicular to the axial direction of the lifting lug connection holes in the upper flat beam connection structure 102 and the lower flat beam connection structure 201. When the upper flat beam 1 and the lower flat beam 2 are connected, the two lifting lug plates in the upper flat beam connection structure 102 are located on the outside of the two lifting lug plates in the lower flat beam connection structure 201, respectively. Then, by using a pin to pass through the corresponding lifting lug connection holes in the upper flat beam connection structure 102 and the lower flat beam connection structure 201 in sequence, the connection between the upper flat beam 1 and the lower flat beam 2 can be achieved. Furthermore, in order to prevent the lifting lug plates in the upper flat beam connection structure 102 and the lower flat beam connection structure 201 on the same pin from shifting along the axial direction of the pin, nuts can be threaded onto both ends of the pin to axially limit the lifting lug plates.

[0030] In this embodiment, a crane connection structure 101 is provided. The crane connection structure 101 is located at the upper center of the upper spreader beam 1. The crane is connected to the crane connection structure 101 located at the center of the upper spreader beam 1 through a pin shaft via a related connector or lifting lug structure. Since the crane connection structure 101 is located at the center of the upper spreader beam 1, it is easier to ensure the balance of the upper spreader beam 1 during the lifting process.

[0031] In this embodiment, three upper flat beam hoisting connection structures 102 are provided, and the three upper flat beam hoisting connection structures 102 are distributed at intervals at the lower end of the upper flat beam 1. From Figure 2 As can be seen, the three upper flat beam hoisting connection structures 102 are located at the center and both ends of the lower end of the upper flat beam 1, respectively, and the upper flat beam hoisting connection structures 102 located at both ends are symmetrically distributed about the upper flat beam hoisting connection structure 102 located at the center.

[0032] In this embodiment, two lower flat beam connecting structures 201 are provided, and the two lower flat beam connecting structures 201 are respectively disposed on both sides of the upper end of the lower flat beam 2. When the upper flat beam 1 is connected to the lower flat beam 2, the two lower flat beam connecting structures 201 are respectively connected to the two upper flat beam hoisting connecting structures 102 located at both ends of the upper flat beam 1 by means of pins.

[0033] In this embodiment, four lower flat beam hoisting structures 202 are provided, and the four lower flat beam hoisting structures 202 are distributed at intervals on the upper end of the lower flat beam 2. Of course, those skilled in the art can adjust the specific number and distribution position of the lower flat beam hoisting structures 202 according to the actual situation, and are not limited to this one method.

[0034] In this embodiment, as Figure 3 As shown, the lower spreader beam hoisting structure 202 includes two rectangular limiting plates 2021. The two limiting plates 2021 in each lower spreader beam hoisting structure 202 are arranged in parallel and welded vertically to the upper surface of the lower spreader beam 2. In actual use, the middle part of the hoisting rope can pass through the gap between the two limiting plates 2021, and the two ends of the hoisting rope are located below the lower spreader beam 2 and are used to bind and fix the component to be hoisted.

[0035] In this embodiment, an arc-shaped plate 2022 is provided between the two limiting plates 2021, and the lower end of the arc-shaped plate 2022 is fixed to the upper surface of the lower flat beam 2. When the hoisting rope passes through the gap between the two limiting plates 2021, the hoisting rope will contact the arc-shaped plate 2022, thereby effectively reducing the friction of the hoisting rope and extending the service life of the hoisting rope.

[0036] In this embodiment, both the upper flat beam 1 and the lower flat beam 2 can be common steel beam structures, which are sturdy and have a long service life.

[0037] In this embodiment, the steel beam structure includes an upper horizontal plate and a lower horizontal plate, which are arranged parallel to each other and are both horizontal. The upper and lower horizontal plates are fixed together by at least one vertical plate, that is, the upper end of the vertical plate is fixedly connected to the upper horizontal plate, and the lower end of the vertical plate is fixedly connected to the lower horizontal plate. When there is only one vertical plate, the steel beam structure is a common I-beam. To further enhance the overall strength of the steel beam structure, such as... Figure 3 As shown, two or more vertical panels can be installed.
