[0045] In order to strengthen and improve the node where the crane and the roof beam are suspended on the original basis, so as to meet the requirements of crane operation, a roof beam suspension node structure for suspending a crane is proposed in the embodiment of the present application. Figure 1 This is a front view of a roof beam suspension node structure for suspending a crane in an embodiment of the utility model. Figure 2 for Figure 1 The cross-sectional view at A-A in the figure is as follows: Figure 1 and Figure 2 As shown, the roof beam suspension node structure for suspending a crane may include: a roof beam body 1, which has a first side wall 11 and a second side wall 12, and a bottom wall 13; a first side steel plate and a second side steel plate 3; a first bottom wall steel plate 4; a third side steel plate 5 and a fourth side steel plate 6; a second bottom wall steel plate 7; and at least one bolt 8 and a nut.

[0046] Among them, the first lateral steel plate and the second lateral steel plate 3 are respectively arranged on the first side wall 11 and the second side wall 12. The first lateral steel plate and the second lateral steel plate 3 are arranged opposite to each other. The first lateral steel plate is connected to the roof beam body 1 through at least one first fixing member. The second lateral steel plate 3 is connected to the roof beam body 1 through at least one second fixing member 112. When there are multiple first fixing members, the first fixing members are arranged along the horizontal extension direction of the first lateral steel plate. When there are multiple second fixing members 112, the second fixing members 112 are arranged along the horizontal extension direction of the second lateral steel plate 3. The first fixing member and the second fixing member 112 can be bolts 8, or other fixing members that can pass through the first lateral steel plate or the second lateral steel plate 3 and be nailed into the roof beam body 1, so as to realize that the first lateral steel plate and the second lateral steel plate 3 are fixed to the roof beam body 1.

[0047] The first bottom wall steel plate 4 is arranged at the bottom wall 13, that is, the first bottom wall steel plate 4 is located at the lower part of the bottom wall 13 and is arranged parallel to the bottom wall 13. The first bottom wall steel plate 4 is connected with the first side steel plate and the second side steel plate 3, and the fixed connection can generally be achieved by welding, that is, the lower end surface of the first side steel plate, the lower end surface of the second side steel plate 3 and the upper end surface of the first bottom wall steel plate 4 are welded.

[0048] The first side steel plate, the second side steel plate 3, the first bottom wall steel plate 4, the first fixing member and the second fixing member 112 can be the original roof beam suspension node structure for connecting the suspension track. Since the load at the original crane node is small, a small number of first fixing members and second fixing members 112 can make the connection strength between the first side steel plate, the second side steel plate 3 and the roof beam body 1 meet the requirements. However, due to the increase in load, the original structure of the roof beam at the node where the crane is installed cannot bear the increased load, and the node where the crane and the roof beam are suspended needs to be reinforced and improved on the original basis to meet the needs of crane operation.

[0049] On the basis of the above, the third lateral steel plate 5 and the fourth lateral steel plate 6 are respectively arranged on the first side wall 11 and the second side wall 12. The third lateral steel plate 5 and the fourth lateral steel plate 6 are respectively arranged parallel to the first side wall 11 and the second side wall 12. The third lateral steel plate 5 and the fourth lateral steel plate 6 are arranged opposite to each other. The third lateral steel plate 5 is located next to the first lateral steel plate, and the third lateral steel plate 5 is connected to the first lateral steel plate, for example, the end of the third lateral steel plate 5 can be aligned with the end of the first lateral steel plate by welding and then connected. The fourth lateral steel plate 6 is located next to the second lateral steel plate 3, and the fourth lateral steel plate 6 is connected to the second lateral steel plate 3, for example, the end of the fourth lateral steel plate 6 can be aligned with the end of the second lateral steel plate 3 by welding and then connected.

[0050] The second bottom wall steel plate 7 is arranged at the bottom wall 13. The first bottom wall steel plate 4 is connected to the third side steel plate 5, the fourth side steel plate 6 and the first bottom wall steel plate 4. For example, the upper end surface of the second bottom wall steel plate 7 can be connected to the lower end surface of the third side steel plate 5 and the lower end surface of the fourth side steel plate 6 by welding, and the end of the second bottom wall steel plate 7 in the horizontal direction is connected to the end of the first bottom wall steel plate 4 in the horizontal direction by welding.

[0051] The bolts 8 pass through the third side steel plate 5, the roof beam 1, and the fourth side steel plate 6 and are screwed into the nuts, and the third side steel plate 5 and the fourth side steel plate 6 are fixed to the roof beam 1 in the above manner. According to the increase in the load of the crane, the number of bolts 8 and nuts can be reasonably set to meet the load requirements.

[0052] In the present application, the third side steel plate 5, the fourth side steel plate 6, and the second bottom wall steel plate 7 are added to the roof beam body 1, and the bolts 8 are passed through the third side steel plate 5, the roof beam body 1, and the fourth side steel plate 6 and screwed into the nuts, so that the added third side steel plate 5, the fourth side steel plate 6, and the second bottom wall steel plate 7 are integrated with the roof beam body 1. At the same time, the third side steel plate 5, the fourth side steel plate 6, and the second bottom wall steel plate 7 are connected to the first side steel plate, the second side steel plate 3, and the first bottom wall steel plate 4 respectively, so that the first fixing part and the second fixing part 112 of the original hanging point and the newly added bolt 8 that plays a shearing role can be made into an integral node, which is jointly subjected to force to share the concentrated force of the hanging point, so that the node can form an integral force with the roof beam body 1 under the action of the concentrated force, thereby meeting the requirements of the suspension crane during operation.

[0053] In order to form an integral body between the bolt 8 and the roof beam 1 , anchoring glue may be filled between the bolt 8 and the roof beam 1 , which helps to increase the size of the bolt 8 fixed with the anchoring glue and further improve the shear resistance of the bolt 8 .

[0054] In order to further improve the connection strength between the side steel plates, the bottom wall steel plates and the roof beam body 1, it is feasible that the third side steel plate 5 is connected to the first side wall 11 of the roof beam body 1 by a steel bonding method. And / or, the fourth side steel plate 6 is connected to the second side wall 12 of the roof beam body 1 by a steel bonding method. And / or, the second bottom wall steel plate 7 is connected to the bottom wall 13 of the roof beam body 1 by a steel bonding method. The above method can achieve the purpose of strengthening the side steel plates, the bottom wall steel plates and the roof beam body 1.

[0055] Similarly, as feasible, the first side steel plate can be connected to the first side wall 11 of the roof beam body 1 by a steel bonding method. And / or, the second side steel plate 3 can be connected to the second side wall 12 of the roof beam body 1 by a steel bonding method. And / or, the first bottom wall steel plate 4 can be connected to the bottom wall 13 of the roof beam body 1 by a steel bonding method.

[0056] The two sides of the first bottom wall steel plate 4 are respectively beyond the first side steel plate and the second side steel plate 3 in the horizontal direction. In this way, the first bottom wall steel plate 4 can be easily welded to the first side steel plate and the second side steel plate 3.

[0057] Further, the roof beam suspension node structure for suspending the crane may include: at least one first rib plate and at least one second rib plate 92. One side of the first rib plate is welded to the first side steel plate, and the lower end of the first rib plate is welded to the upper end face of the first bottom wall steel plate 4, thereby improving the firmness of the connection between the first bottom wall steel plate 4 and the first side steel plate. One side of the second rib plate 92 is welded to the second side steel plate 3, and the lower end of the second rib plate 92 is welded to the upper end face of the first bottom wall steel plate 4, thereby improving the firmness of the connection between the first bottom wall steel plate 4 and the second side steel plate 3.

[0058] Similarly, both sides of the second bottom wall steel plate 7 exceed the third side steel plate 5 and the fourth side steel plate 6 in the horizontal direction. This makes it easier for the second bottom wall steel plate 7 to be welded to the third side steel plate 5 and the fourth side steel plate 6. Further, the roof beam suspension node structure for suspending a crane may include: at least one third rib plate 101, one side of the third rib plate 101 is welded to the third side steel plate 5, and the lower end of the third rib plate 101 is welded to the upper end face of the second bottom wall steel plate 7; at least one fourth rib plate 102, one side of the fourth rib plate 102 is welded to the fourth side steel plate 6, and the lower end of the fourth rib plate 102 is welded to the upper end face of the second bottom wall steel plate 7. In the above manner, the firmness of the connection between the second bottom wall steel plate 7 and the third side steel plate 5 and the fourth side steel plate 6 can be improved, so that the second bottom wall steel plate 7 can be connected to a suspension crane with a higher load level. For example, openings 71 are provided on both sides of the second bottom wall steel plate 7 at positions that respectively exceed the third side steel plate 5 and the fourth side steel plate 6 in the horizontal direction, and the openings 71 are used to connect the suspension rails.

[0059] As a feasible method, there can be multiple third ribs 101, and multiple third ribs 101 are arranged along the extension direction of the third lateral steel plate 5. There can be multiple fourth ribs 102, and multiple fourth ribs 102 are arranged along the extension direction of the third lateral steel plate 5. The position of the third rib 101 corresponds to the position of the fourth rib 102. There can be multiple bolts 8, and multiple bolts 8 are arranged along the extension direction of the third lateral steel plate 5, and the bolts 8 are arranged at intervals from the third rib 101, and the bolts 8 are arranged at intervals from the fourth rib 102. Through the above method, the force of each component and each position of the roof beam body 1 can be made more uniform, avoiding excessive local force and easy damage.
