[0029] The following further elaborates on the present application in conjunction with the attached Figures 1 - 3 for a more detailed description.

[0030] The embodiment of the present application discloses a multi-functional rotary boom device.

[0031] A multi-functional rotary boom device includes a transportation component, a telescopic boom, and a lifting tool component. There are two telescopic booms, both of which are installed on the transportation component. The telescopic boom is rotationally matched with the transportation component in the vertical plane through the rotary drive unit 2. The lifting tool component is located between the two telescopic booms and is connected to the two telescopic booms.

[0032] When lifting an object, the lifting tool component is moved close to the object through the transportation component to connect the lifting tool component and the object. Then, the object is lifted by the telescopic boom, and the object is transported to the placement position through the mutual cooperation of the transportation component and the telescopic boom.

[0033] In the embodiment of the present application, the transportation component is a flatbed transporter for moving within the operation area.

[0034] Each telescopic boom includes a plurality of booms 1, which are distributed along the length direction of the boom 1. Adjacent two booms 1 slide along the length direction of the boom 1 through the telescopic drive unit 3. In the embodiment of the present application, there are two booms 1.

[0035] Each boom 1 is arranged in a cylindrical shape. One end of the boom 1 is closed, and the other end of the boom 1 is provided with an opening. Adjacent two booms 1 are nested and matched, and the openings of the two booms 1 are close to each other. In the embodiment of the present application, the booms 1 are all square tubes.

[0036] The telescopic drive unit 3 is located inside the boom 1. In the embodiment of the present application, the telescopic drive unit 3 is a telescopic oil cylinder. The two ends of the telescopic oil cylinder correspond to the two booms 1 one by one. The end of the telescopic oil cylinder is connected to the corresponding boom 1, and the length direction of the telescopic oil cylinder is the same as the length of the boom 1. By changing the overall length of the telescopic oil cylinder, adjacent two booms 1 slide relative to each other, so as to realize the change of the overall length dimension of the telescopic boom, and improve the convenience of changing the overall length dimension of the telescopic boom.

[0037] At the same time, since the openings of the two booms 1 are close to each other, when changing the relative positions of the two booms 1 through the telescopic oil cylinder, the telescopic oil cylinder further enhances the overall strength of the telescopic boom and reduces the possibility of the telescopic boom being bent due to stress.

[0038] In order to improve the sliding stability of adjacent two booms 1, a limiting slider is fixedly installed on the inner wall of the boom 1, and a limiting chute is formed on the outer wall of the boom 1 along the length direction of the boom 1. The limiting slider is slidably matched with the limiting chute.

[0039] The end of the boom 1 of the telescopic boom close to the flatbed transporter is rotatably matched with the flatbed transporter. In the embodiment of the present application, the rotary drive unit 2 is a rotary oil cylinder, and the rotary oil cylinder is installed between the flatbed transporter and the boom 1 of the telescopic boom.

[0040] When it is necessary to rotate the telescopic boom in the vertical plane, the rotary oil cylinder drives the whole telescopic boom to rotate in the vertical plane, so as to improve the convenience of the rotation of the telescopic boom.

[0041] At the same time, by driving the telescopic boom to rotate through the rotary oil cylinder, it is convenient for the telescopic boom to be in a certain working angle for a long time. Furthermore, it is convenient for the lifted item to be in a vertically downward state for a long time, and the transportation stability of the lifted item is improved.

[0042] In order to reduce the influence of external impurities on the operation of the rotary oil cylinder, a protective cover 8 is also installed at the rotary oil cylinder.

[0043] The lifting tool assembly includes a mounting rod 4 and a hook.

[0044] The mounting rod 4 is horizontally arranged, and the two ends of the mounting rod 4 correspond to the two telescopic booms one by one. The end of the mounting rod 4 is fixedly connected to the end of the corresponding telescopic boom away from the boom 1 of the transportation component.

[0045] A number of mounting units are installed on the mounting rod 4 along the mounting rod 4. Each mounting unit includes two baffles 41. The two baffles 41 are parallel to each other, and an installation area is formed between the two baffles 41 and the mounting rod 4.

[0046] The hook includes a connecting ring sleeved on the mounting rod 4 and a hook 7 mounted on the connecting ring. The connecting ring includes a connecting rod 5 arranged in a U shape and connecting pins 6 detachably mounted at both ends of the connecting rod 5, and the hook 7 is mounted on the connecting pins 6.

[0047] According to the position where the item needs to be lifted, the hook is installed in different installation areas to increase the range of items that can be lifted. After the hook is installed in the installation area, the two baffle plates 41 and the mounting rod 4 limit the hook, thereby improving the working stability of the hook and reducing the possibility of the hook sliding on the mounting rod 4.

[0048] When installing the hook in the installation area, place the connecting rod 5 between the two baffle plates 41, support the connecting rod 5 through the mounting rod 4, and pre - hang the hook 7 on the connecting pins 6. Then, install the connecting pins 6 at both ends of the connecting rod 5 to complete the installation of the hook, improving the convenience of installing and disassembling the hook.

[0049] The implementation principle of the multifunctional rotating jib device in the embodiment of the present application is as follows: When it is necessary to lift an item, the telescopic jib and the lifting tool assembly are transported to a position close to the item by a flatbed transporter. Then, the hook is installed on the mounting rod 4. Through the mutual cooperation of the rotary oil cylinder and the telescopic oil cylinder, the telescopic jib lifts the item through the hook and keeps the item in a stable state with the vertical downward direction for a long time. After transporting the item to a position near the place where it needs to be placed by the flatbed transporter, the item is placed at the set position again through the mutual cooperation of the rotary oil cylinder and the telescopic oil cylinder, thereby improving the efficiency and stability of transporting the item.

[0050] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
