[0002] In order to ensure air circulation in the tunnel, a jet fan is installed on the top of the tunnel in tunnel engineering. The installation of the jet fan requires embedding installation components in the tunnel roof slab. The existing technology usually uses four embedded steel plates as connectors for hoisting the jet fan. Each steel plate has four ribs connected to the main reinforcement at the top of the tunnel roof slab. The bearing capacity for hoisting the jet fan is mainly provided by the friction between the ribs and the concrete and the connection between the ribs and the top main reinforcement. The force on this kind of embedded part is relatively simple, and the connection quality between the ribs and the top main reinforcement is the key to ensuring the bearing capacity. Once the connection quality is poor, the bearing capacity of the embedded part will be greatly reduced. Summary of the Invention

[0036] Referring to Figures 1 to 3 , in order to ensure air circulation in the tunnel, jet fans are installed on the top of the tunnel in tunnel engineering. The installation of jet fans requires embedding installation components in the tunnel roof slab. The fan installation components in the prior art include a bottom plate 70 and support ribs 80. The support ribs 80 are perpendicularly connected to the bottom plate 70 and are connected to the main reinforcement bars in the tunnel roof slab. After the construction and installation are completed, the support ribs 80 are embedded in the concrete of the tunnel roof slab. Usually, four installation components are embedded as connectors 20 for hoisting the jet fan. Specifically, the jet fan is installed and connected to the bottom plate 70. Each bottom plate 70 is provided with four support ribs 80, and the four support ribs 80 are respectively connected to the main reinforcement bars of the roof slab. The bearing capacity for hoisting the jet fan mainly depends on the friction between the support ribs 80 and the concrete and the connection between the support ribs 80 and the top main reinforcement bars. The force on this embedded installation component is relatively simple, and the connection quality between the support ribs 80 and the top main reinforcement bars is the key to ensuring the bearing capacity. Once the connection quality is poor, the bearing capacity of the embedded part will be greatly reduced.

[0037] Referring to Figure 4 and Figure 5 , the present invention provides a fan installation assembly, including a base 10 for installing a fan, a fixing assembly, and a first fixing member 30. One side of the fixing assembly is connected to the base 10, and the other side has a second installation portion 41.

In some embodiments, the bending directions of the first mounting portion 31 and the second mounting portion 41, which are arranged as hook structures, are opposite to those of the first connecting portion 21 and the fourth connecting portion 23. Setting the opposite directions achieves force balance and also avoids the situation of mutual interference.

[0041] It can be understood that the material of the second fixing member 40 is steel. In some embodiments, the second fixing member 40 is arranged in a plate shape, and the second mounting portion 41 is formed by bending. The cross-sectional shape of the second mounting portion 41 is arc-shaped.
