It should be noted that the drawings provided in the following examples only illustrate the basic concept of the present application in a schematic manner, and the following examples and features in the examples can be combined with each other without conflict.

[0023] Please refer to Figures 1-4 In the embodiment, a crane beam and shoulder beam connecting node structure is disclosed, a damping assembly 3 is arranged between the crane beam 1 and the shoulder beam 2, the damping assembly 3 includes a damping support 301 fixedly arranged on the top of the shoulder beam 2 and a damping pad 302 arranged on the damping support 301, and the crane beam 1 is fixedly connected with the damping pad 302. The damping support 301 is a rigid connecting piece and is welded and fixed on the shoulder beam 2, and is used for providing a stable mounting position for the damping pad 302. In the crane beam and shoulder beam connecting node structure provided above, the damping assembly 3 is arranged between the crane beam 1 and the shoulder beam 2, the damping support 301 of the damping assembly 3 can ensure the stable mounting of the damping pad 302 and the shoulder beam 2, and the crane beam 1 is connected with the damping pad 302, so that the damping pad 302 can effectively absorb and relieve the vibration energy and impact force transmitted by the crane beam 1, thereby effectively reducing the risk of fatigue failure of the shoulder beam 2 and improving the safety of the structure in use. Of course, the crane beam and shoulder beam connecting node structure is simple in structure and convenient to install and construct.

[0024] In the embodiment, the damping support 301 is provided with a top-open damping pad mounting groove 301a, and the damping pad 302 is arranged in the damping pad mounting groove 301a. It can be understood that the shape of the damping pad 302 is conformable to the shape of the damping pad mounting groove 301a. In the structure design, the damping support 301 is provided with the top-open damping pad mounting groove 301a, so that the circumference of the damping pad mounting groove 301a can form effective limiting for the damping pad 302, which is good for improving the use reliability of the damping pad 302 and is also good for improving the service life and damping effect of the damping pad 302, thereby ensuring the overall service life of the crane beam and shoulder beam connecting joint structure and reducing the maintenance cost.

[0025] In the embodiment, the top of the damping pad 302 is fixedly provided with a guide limiting plate 303, the guide limiting plate 303 is vertically slidably arranged in the damping pad mounting groove 301a, and the top of the guide limiting plate 303 is fixedly provided with a connecting pad plate 304 with a top surface higher than the top surface of the damping pad mounting groove 301a, and the crane beam 1 is fixedly connected with the connecting pad plate 304.

It can be understood that, since the top surface of the connecting pad plate 304 is higher than the top surface of the damping pad mounting groove 301a, a space for the compression deformation of the damping pad 302 can be ensured between the crane beam 1 and the damping support 301.

[0026] In the embodiment, the damping support 301 includes a bottom plate 3011 fixedly arranged at the top of the shoulder beam 2 and four groups of side wall plates 3012 arranged at the top of the bottom plate 3011, and the damping pad mounting groove 301a is formed by the bottom plate 3011 and the four groups of side wall plates 3012.
