DETAILED DESCRIPTION

[0020] The specific embodiments of the utility model are further described in detail below by comparing the drawings and the description of the embodiments, the purpose is to help the technical personnel in the field to have a more complete, accurate and in-depth understanding of the inventive concept and technical scheme of the utility model, and to help the implementation.

[0021] As Figs. 1 to 3As shown, the crane hoisting structure includes a hoisting beam 1, the bottom of the hoisting beam 1 is provided with a hook 3, the hook 3 is connected with a lifting appliance body 2, the lifting appliance body 2 is provided with a base plate 4, and the base plate 4 is detachably connected with a limiting rod 5. The hoisting beam 1 and the lifting appliance are connected through the hook 3, and the two are detachable, facilitating separate transportation and on-site assembly, and being suitable for the application of the assembled crane. The base plate 4 can play a supporting and pressure dispersion role, ensuring that the lifting appliance is reliable and durable, and the detachable limiting rod 5 is arranged on the base plate 4, which can meet the support of multiple types of supporting beams. Since the small-size or high-section-height supporting beam component is not easy to stabilize in posture, a pair of limiting rods 5 are arranged on the base plate 4, the stable posture of the hoisted component 15 is maintained through the blocking effect of the limiting rods 5, so that the hoisted component 15 can be accurately positioned on the enclosure or side wall, reducing the construction difficulty; at the same time, the component is prevented from falling out due to unstable center of gravity during hoisting or taking out, reducing the construction safety risk.

[0022] As shown in Fig. 2 , the lifting appliance body 2 is a C-shaped structure, the top of the lifting appliance body 2 is fixedly connected with a first lifting lug 7, and one end of the top of the lifting appliance body 2 is fixedly connected with a counterweight 8. The lifting appliance body 2 is a C-shaped structure, and the lifting appliance opening thereof is lateral, so that the component is hoisted laterally to the installation position or removed from the installation position laterally, thereby avoiding the supporting obstacles, and the lifting appliance body 2 can be smoothly moved to the hoisting position through the movement of the hoisting beam 1, thereby ensuring the normal installation of the component, and thus solving the problem of difficult hoisting due to obstacles. The hoisting beam 1 is connected with a pair of C-shaped lifting appliances through the hook 3, and synchronously lifts both ends of the hoisted component 15, so that both ends thereof are supported, thereby stabilizing the horizontal posture of the hoisted component 15. The counterweight 8 plays a balancing role on the lifting appliance body 2.

[0023] As shown in Fig. 3 , the base plate 4 is provided with a mounting hole 6, the bottom end of the limiting rod 5 is threadedly connected with the mounting hole 6, and the limiting rods 5 are arranged in pairs. The mounting hole 6 is provided with a plurality of threaded connections with the limiting rods 5, and the limiting rods 5 are threadedly connected therewith. For the hoisting of supporting beams of different widths, the positions of the limiting rods 5 on different mounting holes 6 are changed to achieve the effect of adjusting the spacing between the limiting rods 5, thereby meeting the hoisting and stability requirements of multiple types of components; the mounting hole 6 is arranged on the base plate 4, and it will not affect the structural strength of the lifting appliance body 2.

[0024] As shown in Fig. 1 , the top end of the hoisting beam 1 is provided with a second lifting lug 13, the top of the hoisting beam 1 is provided with a third lifting lug 14, and the third lifting lug 14 is located above the hook 3. The second lifting lug 13 is used for connecting with the crane driving structure, and the lifting appliance body 2 is moved to the hoisting position through the crane driving control. The third lifting lug 14 on both sides of the second lifting lug 13 is used for connecting a balance wire rope, which plays a balancing role on the hoisting beam 1, thereby ensuring the balance of the hoisted component 15.

[0025] As shown in Fig. 2As shown, support plates 10 are provided on both sides of the bottom end of the lifting device body 2. The pair of support plates 10 enable the lifting device body 2 to be placed in a vertical position during transportation and storage, reducing the space occupied, facilitating connection with the hook 3, and also reducing transportation and storage costs.

[0026] like Fig. 2 As shown, a baffle 12 is provided on the side of the lifting device body 2. The baffle 12 protects the inner side of the lifting device body 2. It can be made of wood and has a certain buffering effect, while protecting the lifting device body 2 and the lifting component 15.

[0027] like Fig. 2 As shown, the edge of the lifting device body 2 is provided with a flange 9. The flange 9 improves the structural strength of the lifting device body 2, and the inner flange 9 of the lifting device body 2 also expands the support area of ​​the lifting device body 2, which helps to distribute the pressure.

[0028] like Fig. 2 As shown, reinforcing ribs 11 are fixedly connected to both the first lifting lug 7 and the support plate 10. Since the first lifting lug 7 and the support plate 10 are the load-bearing parts of the lifting device body 2, the structural strength of the above components is improved by setting the reinforcing ribs 11, ensuring that the first lifting lug 7 and the support plate 10 do not deform, and the structure is more durable.

[0029] The hoisting method is as follows: Depending on the cross-sectional size of the component to be hoisted, select whether to install or remove the limit rod 5. If the limit rod 5 is installed, adjust the limit rod 5 to a suitable distance on the pad plate 4, while ensuring that the distance between the limit rods 5 on the two sets of lifting bodies 2 is consistent. The crane starts the conveying beam 1 to avoid the supporting obstacles, and moves the lifting body 2 to the installation position to carry out construction and installation.

[0030] This crane lifting structure, through the use of C-shaped lifting tools, solves the problem that conventional lifting tools are difficult to reach the lifting position due to obstruction of support obstacles. The component lifting process is stable and the construction safety risk is low. With the use of detachable limit rod 5, it can adapt to the stable lifting of various types of support beams, improving construction efficiency. The structure is simple, can be assembled and used on site, and is applicable to prefabricated cranes.

[0031] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
