TECHNICAL FIELD

[0001] The utility model belongs to a kind of hoisting device, more particularly to a kind of is used for large net frame hoisting balanced dispersion force device. BACKGROUND

[0002] With the continuous development of building technology, space large-span structure is widely used in various buildings, such as industrial plants, aircraft assembly workshops, large warehouses, and theaters, stadiums, exhibition halls and other civil buildings, meeting people's demand for large space, high-function buildings. At present, large steel structure net frame is a more commonly used space large-span structure. In the traditional hoisting process, a single crane is often used to hoist the net frame. Due to the large weight of the components and the small number of lifting points, the net frame is prone to deformation at the lifting point, which may affect the installation accuracy and increase the possibility of damage to the net frame, thereby causing a major safety accident. To prevent such situations, multiple cranes are usually used for coordinated hoisting operations. However, the coordination is poor, the work efficiency is low, and the crane resources are wasted. Therefore, to ensure that the large net frame does not deform during hoisting and to make full use of crane resources, it is necessary to invent a lifting device that can be installed on the hook of a single crane for hoisting large net frames.

Detailed Implementation

[0021] The embodiments of the present invention will be described in detail below with reference to examples. However, those skilled in the art will understand that the following examples are only for illustrating the present invention and should not be regarded as limiting the scope of the present invention.

[0022] like Figures 1-5 The diagram illustrates a force-dispersing device for balancing large space frame hoisting, comprising a hook 1, a first sling 2, a balancing beam 3, a second sling 4, a self-balancing box-type hoisting steel frame 5, and a third sling 6. The balancing beam 3 is primarily an I-beam, with a first lifting ring 3-1 on the upper side and a second lifting ring 3-2 on the lower side. One end of the first sling 2 is connected to the hook 1 of the crane, and the other end is connected to the first lifting ring 3-1 on the upper part of the balancing beam 3. The self-balancing box-type hoisting steel frame 5 has a third lifting ring 5-1 on the upper side and a fourth lifting ring 5-2 on the lower side. One end of the second sling 4 is connected to the second lifting ring 3-2 on the lower part of the balancing beam 3, and the other end is connected to the third lifting ring 5-1 on the upper side of the self-balancing box-type hoisting steel frame 5. One end of the third sling 6 is connected to the fourth lifting ring 5-2 on the lower side of the self-balancing box-type hoisting steel frame 5, and the other end is connected to the large component 7 being hoisted.

[0023] The self-balancing box-type hoisting steel frame 5 can be composed of multiple hoisting steel frame modules 8 connected by bolt connection devices 9, depending on the size of the component being hoisted.

[0024] The hoisting steel frame module 8 is welded together from steel columns 8-1, steel beams 8-2, and diagonal bracing steel 8-3. Two pairs of bolt pin connecting devices 9 are respectively provided on both sides of the steel frame. The bolt pin connecting devices 9 are staggered from the bolt pin connecting devices 9 at the corresponding positions of adjacent hoisting steel frame modules 8.

[0025] The bolt connection device 9 consists of a bolt support 9-1, a bolt hole 9-2, a bolt 9-3, and a bolt limiter 9-4. The bolt hole 9-2 is fixedly welded to the bolt support 9-1, and the bolt support 9-1 is fixedly welded to the steel column 8-1 of the hoisting steel frame module 8. The bolt 9-3 passes through multiple bolt holes 9-2 simultaneously, thus forming a hinge. The hinge allows the steel frames on both sides to rotate freely without external constraints. The bolt limiter 9-4 restricts the bolt 9-3 from disengaging from the bolt hole 9-2.

[0026] Working principle: Based on the size of the large space frame 7 to be hoisted, determine how many hoisting steel frame modules 8 the self-balancing box-type hoisting steel frame 5 consists of. Align the pin holes 9-2 in adjacent pin connection devices 9, then pass the pins 9-3 through all pin holes 9-2, and then install pin limiters 9-4 to prevent the pins 9-3 from slipping. Then, lift the balance beam 3 using the hook 1 and the first lifting rope 2. After the balance beam 3 is in the air, use the second lifting rope 4 to lift the self-balancing box-type hoisting steel frame 5 as a whole. Finally, after the self-balancing box-type hoisting steel frame 5 is in the air, use the third lifting rope 6 to lift the large space frame 7.

[0027] In the above scheme, the weight of the large space frame is distributed across multiple ropes via the balance beam 3 and the self-balancing box-type lifting steel frame 5, extending from the hook 1. This significantly reduces the concentrated force at each lifting point of the component, thereby minimizing deformation at those points. Furthermore, since the self-balancing box-type lifting steel frame 5 is connected by hinges, it possesses a certain degree of deformation capacity, absorbing the energy generated during the instantaneous start-up process and preventing significant deformation of the component during lifting.
