[0052] In order to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0053] Example 1

[0054] The present invention provides a method and system for determining the connection between communication equipment and power towers.

This method not only improves calculation accuracy but also accurately and efficiently determines the cross-sectional specifications of each component of the connection fixture, ensuring that the connection fixture is safe and reliable when mounting communication equipment.

[0055] The purpose of the present invention is achieved through the following technical solutions:

[0056] The present invention provides a method for determining a connection device between a communication device and an electric power tower, such as Figure 1 Shown, including:

[0057] Obtain the weight of the communication equipment and the angle between the tower main material 1 and the horizontal plane;

[0058] Calculate the parameters of the connecting fixture 2 and the connecting crossbar 3 based on the weight of the communication equipment and the angle between the main tower material 1 and the horizontal plane;

[0060] The communication equipment is connected to the connecting fixture 2 via the connecting crossbar 3 , and the connecting fixture 2 is connected to the main tower material 1 of the power tower by means of bolt connection.

[0061] The parameters include: the pre-tightening force of the bolt, the design strength of the bolt, the thickness of the steel plate in the connecting fixture 2 and the length of the effective extension section, and the cross-sectional strength of the connecting crossbar 3 .

[0063]

[0064] Among them, P fis the pre-tightening force of the bolt, μ is the friction coefficient between the contact surface of the connection fixture 2 and the main material 1 of the tower, θ is the angle between the main material 1 of the tower and the horizontal plane, and G is the weight of the communication equipment.

[0065] The calculation formula for the design strength of the bolt is:

[0068] The calculation formula for the thickness of the steel plate in the connecting fixture 2 and the length of the effective extension section is:

[0069]

[0070] Among them, t is the thickness of the steel plate, e is the effective extension length of the steel plate, f y is the yield strength of the steel plate material, h is the width of the steel plate, d1 is the distance from the top bolt to the center line of the plate, L is the length of the connecting crossbar 3, θ is the angle between the main material 1 of the tower and the horizontal plane, and G is the weight of the communication equipment.

[0071] The calculation formula of the cross-sectional strength of the connecting cross bar 3 is:

[0072]

[0073] Where W is the cross-sectional strength of the connecting crossbar 3, f y is the yield strength of the steel plate material, L is the length of the connecting crossbar 3, θ is the angle between the tower main material 1 and the horizontal plane, and G is the weight of the communication equipment.

[0074] Specifically, the present invention is implemented through the following technical solutions:

[0075] The weight of the communication equipment is transferred from the connection fixture to the tower's main material through the connection device. The connection fixture is connected to the tower's main material using bolts, and the tight connection between the fixture and the tower's main material generates sufficient friction to ensure that the communication equipment is securely mounted.

[0076] Connecting device such as Figures 2 to 6 As shown, it includes: a connecting fixture 2 and a connecting cross bar 3;

[0077] One end of the connecting cross bar 3 is connected to the tower main material 1 through the connecting fixture 2; the other end is connected to the communication equipment.

[0078] The connecting fixture 2 includes: a steel plate with holes and bolts;

[0079] The bolts pass through the holes in the steel plate and are connected to the steel plate;

[0080] The steel plate is connected to the tower main material 1 and the connecting cross bar 3.

[0081] The steel plates include: a first steel plate and a second steel plate of equal thickness;

[0082] The cross section of the first steel plate is a "V" structure with both ends extending outward, the extending portion is connected to the second steel plate, and the hole is provided at the overlapping portion of the first steel plate and the second steel plate;

[0083] The iron tower main material 1 is arranged between the first steel plate and the second steel plate;

[0084] The "V" structure of the first steel plate is connected to the connecting crossbar 3;

[0085] The “V” structure matches the shape and size of the tower main material 1 .

[0086] The connecting cross bar 3 has a square cross section, and one end connected to the connecting fixture 2 matches the "V" structural shape.

[0087] The device further comprises: a U-bolt 4 and a communication equipment mounting vertical rod 5;

[0088] The connecting cross bar 3 is connected to the communication equipment mounting vertical bar 5 through the U-bolt 4;

[0089] The communication device mounting vertical rod 5 is connected to the communication device.

[0090] The parameters of each component of the connection fixture and the parameters of each component of the mounting device are determined as follows:

[0091] 1. Determine the mounting weight G and the angle θ between the main material of the mounted tower and the ground;

[0092] 2. Determine the specifications of the bolts used in component 2, such as Figure 7 As shown;

[0093] The friction between the fixture and the main material must be greater than the component of the mounted weight in the direction of the main material. Whether the connector can have sufficient friction depends on the preload of the bolts, which requires the bolt preload to satisfy the following formula:

[0094]

[0095] Among them, P fis the pre-tightening force of the bolt, μ is the friction coefficient between the contact surface of the connection fixture 2 and the main material 1 of the tower, θ is the angle between the main material 1 of the tower and the horizontal plane, and G is the weight of the communication equipment. It can be obtained by looking up the table and used to select the bolts of the corresponding specifications;

[0096] For the strength calculation of the bolts, the bolt strength should be ensured to meet the following formula:

[0097]

[0098] Where P is the design strength of the bolt, D1 is the distance from the top bolt to the lower end of the connecting plate, D2 is the distance from the bottom bolt to the lower end of the connecting plate, d1 is the distance from the top bolt to the center line of the plate, d2 is the distance from the bottom bolt to the center line of the plate, L is the length of the connecting crossbar 3, θ is the angle between the tower main material 1 and the horizontal plane, and G is the weight of the communication equipment;

[0099] The more conservative bolt specifications are selected by calculating the above two formulas as the bolts used in the connection parts;

[0100] 3. Determine the thickness of the plate and the effective extension length of component 2;

[0101] Under the action of the mounting gravity, the plate 2 must not be plastically deformed, and the plate thickness t and the effective extension length e must satisfy the following formula:

[0102]

[0103] Among them, t is the thickness of the steel plate, e is the effective extension length of the steel plate, f y is the yield strength of the steel plate material, h is the width of the steel plate, d1 is the distance from the top bolt to the center line of the plate, L is the length of the connecting crossbar 3, θ is the angle between the main material 1 of the tower and the horizontal plane, and G is the weight of the communication equipment;

[0104] In the actual production process, the bolt specifications can be matched with the plate thickness t that meets the structural requirements of the steel structure specification, and then the e value can be determined by the above formula;

[0105] 4. Determine the strength of the rectangular steel pipe section;

[0106] Under the action of the load gravity, the ends of the rectangular steel tube are required to not undergo plastic deformation, and the section modulus of the rectangular steel tube must satisfy the following formula:

[0107]

[0108] Where W is the cross-sectional strength of the connecting crossbar 3, f y is the yield strength of the steel plate material, L is the length of the connecting crossbar 3, θ is the angle between the tower main material 1 and the horizontal plane, and G is the weight of the communication equipment;

[0109] According to the W value, select the rectangular steel pipe model from the steel table.

[0110] The above four steps not only improve the calculation accuracy, but also accurately and efficiently obtain the cross-sectional specifications of each component of the connection fixture, ensuring that the connection fixture is safe and reliable when mounting communication equipment.

[0111] The present invention can avoid the problem of insufficient strength of the connection clamp when mounting communication equipment on a transmission iron tower, reduce the amount of steel used while ensuring the stability of the communication equipment, and achieve economic rationality.
