Description

Technical Field

[0001] The utility model relates to the technical field of transmission towers, in particular to a bottom reinforcement structure of a transmission tower. Background Art

[0002] A transmission tower is a support point for overhead lines. If one circuit is erected on the transmission tower, it is a single-circuit transmission tower; if two circuits are erected on the transmission tower, it is a double-circuit transmission tower. A single circuit means a circuit with one power supply for one load; a double circuit means a circuit with two power supplies for one load. Generally, enterprises with high requirements for power supply reliability or important substations in a region all adopt double-circuit power supply, so that in case one power supply fails, the other power supply can continue to supply power.

[0003] When the existing transmission towers are erected, since they are made of steel structures, a reinforcement structure needs to be adopted at the bottom end to reinforce the bottom end of the transmission tower and improve the stability of the transmission tower. However, when reinforcing the transmission tower, the general reinforcement method is to use multiple bolts to fix the bottom end of the tower to the base. However, the reinforcement effect of this reinforcement method is not obvious, and the bolts will corrode and other problems in the harsh external environment, resulting in a reduced service life of the transmission tower. Summary of the Utility Model

[0004] In order to overcome the existing problems, the embodiment of the present application provides a bottom reinforcement structure of a transmission tower. A frame is provided at the bottom end of the tower base. A limiting frame is provided at each of the four corners inside the frame. The limiting frame is a hollow cylindrical structure, and the inner cross-sectional diameter of the limiting frame is the same as the cross-sectional diameter of the limiting column. In this way, the limiting column at the bottom end of the tower base is inserted into the limiting frame, and the depth of the limiting frame is greater than the height of the limiting column. When the limiting column is inserted into the limiting frame, the limiting frame plays a limiting role on the limiting column, avoiding the problem of shaking and deflection of the tower base, and improving the stability of the tower base.

In this way, the limiting column can be protected by the limiting frame, the stability of the overall structure is improved, the problem of shaking and deflection of the iron tower base is avoided, and the stability of the iron tower base is improved.

[0008] Preferably, the limiting frame is a hollow cylindrical structure, and the limiting frame is fixedly connected to the frame. When the frame and the limiting frame are connected to each other, the contact area between the limiting frame and the frame can be increased, so that the limiting frame and the frame are more tightly connected during connection, and the limiting effect of the frame is improved.

[0009] Preferably, the depth of the limiting frame is greater than the height of the limiting column, and the inner circle cross-sectional diameter of the limiting frame is the same as the cross-sectional diameter of the limiting column.

The inclined brace can improve the stability of the iron tower base, so that the stability of the iron tower base is firmly improved under the support of the inclined brace.

[0011] Preferably, the frame is a frame structure, and the intersection of the frame and the limiting frame is a structure with a curvature. In this way, when the frame and the limiting frame are connected to each other, the contact area between the limiting frame and the frame can be increased, so that the limiting frame and the frame are more tightly connected during connection, and the limiting effect of the frame is improved.

[0023] In the embodiment of the present application, a bottom reinforcement structure for a transmission tower is provided to solve the problems in the prior art. A frame is provided at the bottom end of the tower base, and a limiting frame is provided at each of the four corners inside the frame. The limiting frame is a hollow cylindrical structure, and the inner cross-sectional diameter of the limiting frame is the same as the cross-sectional diameter of the limiting column. In this way, the limiting column at the bottom end of the tower base is inserted into the limiting frame, and the depth of the limiting frame is greater than the height of the limiting column. When the limiting column is inserted into the limiting frame, the limiting frame plays a role in limiting the limiting column, avoiding the problem of shaking and deflection of the tower base, and improving the stability of the tower base.

[0024] The technical solution in the embodiment of the present application is to solve the above problems, and the general idea is as follows:

[0025] Embodiment 1:

[0026] This embodiment provides a specific structure of the bottom reinforcement structure of a transmission tower, as follows Figures 1-5 shown, including a tower base 2 and limit columns 5 arranged at the four corners of the bottom end of the tower base 2. The limit columns 5 are fixedly connected to the tower base 2;

[0027] Among them, a limit structure is provided at the bottom end of the tower base 2, which includes a limit frame 3 connected to the limit column 5 and a frame 1 arranged on the outer surface of the limit frame 3. The limit column 5 and the limit frame 3 are inserted into each other. Under the limitation of the frame 1, the tower base 2 is limited. The limit column 5 is recessed inside the limit frame 3, and the height of the limit frame 3 is greater than the height of the limit column 5. In this way, the limit column 5 can be protected by the limit frame 3, the stability of the overall structure is improved, the problem of shaking and deflection of the tower base 2 is avoided, and the stability of the tower base 2 is improved.

[0028] The limit frame 3 is a hollow cylindrical structure, and the limit frame 3 is fixedly connected to the frame 1. When the frame 1 and the limit frame 3 are connected to each other, the contact area between the limit frame 3 and the frame 1 can be increased, so that the limit frame 3 and the frame 1 are more closely connected during connection, and the limiting effect of the frame 1 is improved.

[0029] The depth of the limit frame 3 is greater than the height of the limit column 5. The inner circle cross-sectional diameter of the limit frame 3 is the same as the cross-sectional diameter of the limit column 5. The limit column 5 at the bottom end of the tower base 2 is inserted into the limit frame 3, and the depth of the limit frame 3 is greater than the height of the limit column 5. In this way, when the limit column 5 is inserted into the limit frame 3, the limit frame 3 plays a limiting role on the limit column 5, the problem of shaking and deflection of the tower base 2 is avoided, and the stability of the tower base 2 is improved.

[0030] A cross brace 4 is provided at the top end of the tower base 2. The cross brace 4 is spot welded to the tower base 2. Through the setting of the cross brace 4, when the tower base 2 is connected to the top bracket, the connection is stable under the load of the cross brace 4. An inclined brace 6 is provided on the side of the tower base 2. The connection method of the inclined brace 6 and the tower base 2 is spot welding. The inclined brace 6 can improve the stability of the tower base 2, so that under the support of the inclined brace 6, the stability of the tower base 2 is steadily improved.

[0031] The frame 1 is a frame structure, and the intersection of the frame 1 and the limit frame 3 is a structure with a curvature. In this way, when the frame 1 and the limit frame 3 are connected to each other, the contact area between the limit frame 3 and the frame 1 can be increased, so that the limit frame 3 and the frame 1 are more closely connected during connection, and the limiting effect of the frame 1 is improved.

[0032] The connection method of the tower base 2 and the limit column 5 is casting connection. By integrally connecting the limit column 5 and the tower base 2, the limit column 5 and the tower base 2 can be closely connected, and the limit column 5 plays a role of supporting and bearing the tower base 2.

[0033] By adopting the above technical solutions:

[0034] Under the limitation of the frame 1, the tower base 2 is limited. The limiting column 5 and the limiting frame 3 are inserted into each other. The limiting column 5 is concave inside the limiting frame 3, and the height of the limiting frame 3 is greater than the height of the limiting column 5. In this way, the limiting frame 3 can protect the limiting column 5, improve the stability of the overall structure, avoid the problem of shaking and deflection of the tower base 2, and improve the stability of the tower base 2.

[0035] Embodiment 2:

[0036] This embodiment provides a specific structure of a reinforcement structure at the bottom of a transmission tower, as Figures 1-5 shown, including a tower base 2 and limiting columns 5 arranged at the four corners of the bottom end of the tower base 2. The limiting columns 5 are fixedly connected to the tower base 2;

[0037] Among them, a limiting structure is provided at the bottom end of the tower base 2, which includes a frame 1 connected to the limiting column 5. The limiting column 5 and the limiting frame 3 are inserted into each other. Under the limitation of the frame 1, the tower base 2 is limited, the stability of the overall structure is improved, the problem of shaking and deflection of the tower base 2 is avoided, and the stability of the tower base 2 is improved.

[0038] A cross brace 4 is provided at the top end of the tower base 2. The cross brace 4 is spot welded to the tower base 2. Through the setting of the cross brace 4, when the tower base 2 is connected to the top bracket, the connection is stable under the load of the cross brace 4. An inclined brace 6 is provided on the side of the tower base 2. The connection method of the inclined brace 6 and the tower base 2 is spot welding. The inclined brace 6 can improve the stability of the tower base 2, so that under the support of the inclined brace 6, the stability of the tower base 2 is steadily improved.

[0039] The connection method between the tower base 2 and the limiting column 5 is casting connection. By integrally connecting the limiting column 5 and the tower base 2, the limiting column 5 and the tower base 2 can be closely connected, and the limiting column 5 plays a role in supporting and bearing the tower base 2.

[0040] By adopting the above technical solutions:

[0041] By providing a frame 1 at the bottom end of the tower base 2, the tower base 2 is limited under the action of the frame 1, and the stability of the limitation is improved.

[0042] Comparing Comparative Example 1 and Example 2, it can be seen that: a frame 1 is provided at the bottom end of the tower base 2, and a limit frame 3 is provided at each of the four corners inside the frame 1. The limit frame 3 is a hollow cylindrical structure, and the inner cross-sectional diameter of the limit frame 3 is the same as the cross-sectional diameter of the limit column 5. In this way, the limit column 5 at the bottom end of the tower base 2 is inserted into the limit frame 3, and the depth of the limit frame 3 is greater than the height of the limit column 5. When the limit column 5 is inserted into the limit frame 3, the limit frame 3 plays a role in limiting the limit column 5, avoiding the problem of shaking and deflection of the tower base 2, and improving the stability of the tower base 2.

[0043] Finally, it should be noted that: Obviously, the above embodiments are only examples given for clearly explaining the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. The obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
