Description

Technical Field

[0001] This invention relates to the field of flange reinforcement equipment technology, specifically a carbon fiber reinforcement device for flanges inside communication towers. Background Technology

[0002] Flanges are components used to connect the ends of circular pipes in communication base stations; they are also used on equipment to connect two devices, such as speed reducer flanges. A flange connection, or flange joint, refers to a detachable connection consisting of a flange, gasket, and bolts forming a sealed assembly. Flange structures are divided into external flange structures and internal flange structures. Internal flange structures are mainly located inside the space between circular pipes and are fastened and connected using bolts.

[0003] In the existing technology, the specific reinforcement method is to install locking devices at both the upper and lower parts of the inner flange node. The locking device consists of two semi-circular locking connections and is fixed to the surface of the tower body. The locking blocks on the same vertical axis of the upper and lower locking devices are connected and fixed by fixing screws. Multiple thrust blocks are fixed on the tower body above the upper locking device to prevent the locking device from detaching from the tower body. However, since the diameter of the cylinder is different at the upper and lower parts of the inner flange where the locking devices are installed, the upper and lower locking devices need to be modified a lot, which makes it difficult to guarantee the strength of the inner flange structure in the existing technology.

[0014] The fifth position is located at a second distance above the bottom of the fastening plate;

[0015] The sixth position is located between the fourth position and the fifth position.

[0016] Furthermore, the fastening plates are arranged parallel to each other, and the distance between two adjacent fastening plates is greater than or equal to millimeters, while the distance between two adjacent fastening plates is less than or equal to millimeters; the fastening band has a multi-layer structure.

[0017] Furthermore, both the first and second fasteners are made of carbon fiber material.

[0018] Furthermore, the inner wall of the fastening band is provided with several pressure rods, the inside of the fastening sleeve is provided with several cavities, the outer wall of the fastening sleeve is provided with an inlet on one side of the cavity, the outer wall of the fastening sleeve is provided with an outlet on the other side of the cavity, a rotatably connected support cylinder is provided on one side of the inner wall of the cavity, the outer wall of the support cylinder is provided with an annular guide groove that matches the fastening band, the outer wall of the support cylinder is provided with a connecting groove that matches the pressure rods on the inner side of the annular guide groove, and a number of flexible pads are provided on one side of the inner wall of the connecting groove.

[0019] Furthermore, the inner wall of the cavity is provided with a first guide roller and a second guide roller rotatably connected to one side of the support cylinder.

[0021] Furthermore, the distance between two adjacent pressure rods is less than half the inner diameter of the pressure rod, the width of the fastening plate is greater than twice the outer diameter of the pressure rod, and the width of the fastening plate is less than three times the outer diameter of the pressure rod; the number of cavities is the same as the number of fastening bands, and the entry point is aligned with the fastening band.

[0022] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0023] This invention reinforces the inner flange node of a single-tube communication tower by setting a first fastener, a second fastener, a fastening plate, and a fastening band, thereby improving the load-bearing capacity of the inner flange structure. The reinforcement device is installed at the inner flange node of the single-tube tower, with a first fastener and a second fastener at the node. The first fastener is fixed to the outside of the circular tube in the direction of the tube to improve its load-bearing capacity. The second fastener is fixed to the side of the first fastener facing the tube by wrapping and pasting, i.e., the second fastener binds the first fastener to the outside, further improving the tube's load-bearing capacity. Compared to existing methods for fastening inner flange nodes, this invention provides a more efficient fixation, solves the problem of insufficient strength in the bolts and stiffening plates at the inner flange node, and reduces the stress amplitude of the bolts at the inner flange node, thus improving the load-bearing capacity of the inner flange structure.

[0024] In this invention, a fastening sleeve, a pressure rod, a cavity, a support cylinder, a connecting groove, a pawl, and a ratchet are used. First, the fastening plate of the first fastener is tightly and fixed to the surface of the communication tower. The second fastener is wrapped around the outside of the fastening plate. After the fastening band enters the fastening sleeve, it moves along the annular guide groove. The pressure rod is inserted into the connecting groove. As the fastening band moves continuously, the pressure rod continuously inserts, connects, separates, and is pulled out of the connecting groove. The operation is convenient and quick. During the tightening process of the fastening band, the support cylinder rotates counterclockwise under the combined action of the pressure rod and the connecting groove. During the counterclockwise rotation, the pawl moves inward to the inside of the mounting groove under the counterclockwise rotation of the ratchet. The interaction between the pawl and the ratchet locks the clockwise rotation of the ratchet, effectively preventing the support cylinder from rotating clockwise. At the same time, the pressure rod limits the position inside the connecting groove, effectively preventing the fastening band from retracting after the position is locked, ensuring the fastening band's tightening and fixing effect. The pressure rod can also apply pressure to clamp the fastening plate, further strengthening the fixing effect of the fastening plate and enhancing the fixing connection between the fastening plate and the communication tower surface.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] like Figure 1-2 The invention relates to a carbon fiber reinforcement device for an internal flange of a communication tower, comprising a first fastener and a second fastener. The first fastener comprises a plurality of fastening plates 1, and the second fastener comprises a fastening sleeve 2 and a plurality of fastening bands 3. The fastening bands 3 are located on the outside of the fastening plates 1 and are perpendicular to the fastening plates 1. One end of the fastening band 3 is fixedly connected to the outer wall of the fastening sleeve 2, and the other end of the fastening band 3 passes through the fastening sleeve 2 and is connected to the fastening sleeve 2.

[0035] The center of the outer wall of the fastening plate 1 is flush with the cross-section where the flange node inside the communication tower is located. The surface of the fastening plate 1 is in contact with the surface of the communication tower, and the length of the fastening plate 1 is greater than twice the outer diameter of the communication tower. The fastening bands 3 are divided into two groups. The first group of fastening bands 3 is located above the cross-section where the flange node inside the communication tower is located, and the second group of fastening bands 3 is located below the cross-section where the flange node inside the communication tower is located. Both the first group of fastening bands 3 and the second group of fastening bands 3 are perpendicular to the length direction of the communication tower. The first group of fastening bands 3 includes three fastening bands 3, which are respectively located at the first, second, and third positions above the cross-section where the flange node inside the communication tower is located. The second group of fastening bands 3 includes three fastening bands 3, which are respectively located at the fourth and fifth positions below the cross-section where the flange node inside the communication tower is located. The first position is located above the cross-section of the flange node inside the communication tower at a first distance; the second position is located below the top of the fastening plate 1 at a second distance; the third position is located between the first position and the second position; the fourth position is located below the cross-section of the flange node inside the communication tower at a first distance; the fifth position is located above the bottom of the fastening plate 1 at a second distance; the sixth position is located between the fourth position and the fifth position; the fastening plates 1 are arranged parallel to each other, and the distance between two adjacent fastening plates 1 is greater than or equal to 10 mm and the distance between two adjacent fastening plates 1 is less than or equal to 30 mm; the fastening band 3 has a multi-layer structure; the first fastener and the second fastener are both made of carbon fiber material.

[0036] The specific implementation method is as follows: In use, a first fastener, a second fastener, a fastening plate 1, and a fastening band 3 are provided;

[0037] The reinforcement device in this invention is installed at the inner flange node of the single-tube communication tower. For the selection of the inner flange node, the stress at the selected inner flange node can be tested, and the reinforcement device in this invention can be installed on the inner flange node that needs to improve the load-bearing capacity.

[0038] The first fastener includes N fastening plates 1, and the N fastening plates 1 are fixedly installed on the outside of the inner flange node of the circular pipe in the direction of the circular pipe of the single-tube communication tower, that is, the N fastening plates 1 are installed in parallel directions; wherein, the center of symmetry of the N fastening plates 1 in the direction of the circular pipe can be the cross section at the inner flange node, that is, the N fastening plates 1 are installed with equal lengths in both the upward and downward directions from the cross section at the inner flange node, thereby improving the load-bearing capacity of the circular pipe at the inner flange node.

[0039] In addition, the N fastening plates 1 included in the first fastener mentioned above may be made of carbon fiber material or other materials that can improve the strength of the flange joint inside the round pipe. This embodiment of the invention does not limit this.

[0040] The aforementioned second fastener includes M fastening bands 3, and the M fastening bands 3 are fixedly arranged on the side opposite to the N fastening plates 1 facing the communication tower in the direction of the circular tube of the communication tower single tube tower. That is, the M fastening bands 3 are fixedly arranged on the outside of the N fastening plates 1. Of course, the M fastening bands 3 can be arranged by wrapping around the fastening plates 1 or by welding to the fastening plates 1. Therefore, the arrangement of the aforementioned second fastener can be arranged according to the actual size and actual needs of the communication tower single tube tower. This embodiment of the present invention does not limit this.

[0041] In addition, the M fastening bands 3 included in the second fastener may be made of carbon fiber material or other materials that have a better fixing effect with the first fastening component 11. This embodiment of the invention does not limit this.

[0042] In this embodiment, the first fastener is fixedly installed on the outside of the circular tube at the inner flange node of the communication tower single tube tower in the direction of the circular tube of the communication tower single tube tower, which improves the load-bearing capacity of the inner flange node of the circular tube. In addition, the second fastener is fixedly installed on the side of the fastening plate 1 facing the communication tower single tube tower in the direction perpendicular to the circular tube of the communication tower single tube tower, which improves the load-bearing capacity of the first fastener. The reinforcement device of the present invention is installed at the inner flange node corresponding to the communication tower single tube tower, which improves the load-bearing capacity of the inner flange structure.

[0043] It should be noted that the reinforcement device of the present invention can reduce the maximum tensile force of the bolts at the inner flange node. For example, by setting a first fastening component made of 1200 mm carbon fiber, the maximum tensile force of the bolts at the inner flange node can be reduced by 20% to 30%. Furthermore, when the bolts at the reinforced inner flange node and the unreinforced inner flange node reach the same tensile force, the load required by the reinforced inner flange node is 20% to 40% higher than that of the unreinforced node, that is, the bearing capacity is increased by 20% to 40%.

[0044] In addition, under large loads, the stress at the carbon fiber plate can reach 300 MPa, indicating that the carbon fiber plate on the tension side plays a significant role in sharing the tensile force during the bending process of the cylinder. Under smaller loads, adding carbon fiber plates can reduce the prestress loss of high-strength bolts, thereby reducing the possibility of fatigue failure.

[0045] As an optional implementation, the N fastening plates 1 are arranged with equal lengths in both the vertical and horizontal directions, starting from the cross-section where the inner flange node is located. In this implementation, the symmetrical points of the N fastening plates 1 in the vertical direction are located on the same plane, and this plane is the cross-section of the inner flange node, so that the extension lengths of the N fastening plates 1 in both the vertical and horizontal directions are the same. Through this structural arrangement, the lengths of the first fastener above and below the inner flange node are equal, thereby improving the load-bearing capacity of the inner flange structure.

[0046] As an optional implementation, the N fastening plates 1, starting from the cross-section of the inner flange node, have a length in both the upward and downward directions greater than or equal to the diameter of the single-tube communication tower; at the corresponding inner flange node, the length of the first fastening component, starting from the cross-section at the inner flange node, in both the upward and downward directions can be obtained by the following formula:

[0047] Lc = max(150t + 200, D)

[0048] Where Lc is the single-sided extension length of the first fastening component, t is the thickness of the first fastening component, and D is the diameter of the cylinder, all in millimeters.

[0049] The length of the first fastener at the inner flange node, starting from the cross-section, in both the upward and downward directions, can be determined by first obtaining the diameter of the single-tube communication tower and auxiliary data. Specifically, the auxiliary data is 150 multiplied by the thickness of the first fastener plus 200. It should be noted that the units are all in millimeters. The unilateral extension length of the first fastener is determined by comparing the diameter of the single-tube communication tower and the auxiliary data. The specific value is the larger of the diameter of the single-tube communication tower and the auxiliary data. After obtaining the unilateral extension length of the first fastener, the overall length of the first fastener can be determined.

[0050] It should be noted that when calculating the bending moment borne by the first fastening component, 300 MPa can be used as the stress value, and the bending moment of the first fastening component also needs to be multiplied by a reduction factor, which can be 0.8.

[0051] In this embodiment, the length of the first fastener is determined based on the dimensions of the single-tube communication tower and the thickness of the fastening component. Similarly, the width of the first fastener is also selected based on the actual situation of the circular tube. The length and width of the first fastener should not be too large. In terms of length, an excessively long first fastener will result in poor economic efficiency. In terms of width, an excessively wide first fastener will cause an excessive gap with the surface of the single-tube communication tower, thereby reducing the load-bearing capacity when the first fastener is installed. In this embodiment of the invention, by setting the dimensions of the first fastener, the load-bearing capacity of the inner flange structure is improved.

[0052] As an optional implementation, the M fastening bands 3 are divided into a first group of fastening bands 3 and a second group of fastening bands 3. The first group of fastening bands 3 is located above the cross-section where the inner flange node is located, and the first group of fastening bands 3 is fixedly installed on the side of the N fastening plates facing the communication tower single-tube tower with the circular tube direction perpendicular to the communication tower single-tube tower. The second group of fastening bands 3 is located below the cross-section where the inner flange node is located, and the second group of fastening bands 3 is fixedly installed on the side of the N fastening plates facing the communication tower single-tube tower with the circular tube direction perpendicular to the communication tower single-tube tower.

[0053] The aforementioned M fastening bands 3 are divided into the aforementioned first group of fastening bands 3 and the aforementioned second group of fastening bands 3. The aforementioned first group of fastening bands 3 and the aforementioned second group of fastening bands 3 are respectively located above and below the cross section where the aforementioned inner flange node is located, and are both fixedly installed on the side of the aforementioned N fastening plates facing the aforementioned single-tube communication tower in a direction perpendicular to the circular tube of the communication tower. That is, the aforementioned first group of fastening bands 3 and the aforementioned second group of fastening bands 3 can be fixed to the outside of the aforementioned fastening plates by wrapping or pasting.

[0054] It should be noted that the number of fastening bands 3 in the first group of fastening bands 3 can be determined according to the length of the fastening plate and the size of the single-tube communication tower. The number of fastening bands 3 in the second group of fastening bands 3 can be determined according to the length of the fastening plate 1 and the size of the single-tube communication tower. In addition, the first group of fastening bands 3 and the second group of fastening bands 3 can be symmetrically distributed at the cross-section where the inner flange node is located. This structure improves the load-bearing capacity of the inner flange structure.

[0055] As an optional implementation, the first set of fastening bands 3 includes three fastening bands 3, respectively disposed at a first position, a second position, and a third position above the cross-section of the inner flange node. The first set of fastening bands 3 is fixedly disposed at the first position, a second position, and a third position of the N fastening plates facing the opposite side of the communication tower single-tube tower, perpendicular to the circular tube direction of the communication tower single-tube tower. The second set of fastening bands 3 includes three fastening bands 3, respectively disposed at a fourth position, a fifth position, and a sixth position below the cross-section of the inner flange node. The second set of fastening bands 3 is fixedly disposed at the fourth position, a fifth position, and a sixth position, perpendicular to the circular tube direction of the communication tower single-tube tower. The N fastening plates are positioned at the fourth, fifth, and sixth positions on the opposite side of the single-tube communication tower. The first position is located at a first distance above the cross-section where the inner flange node is located. The second position is located at a second distance below the top of the plurality of fastening plates 1. The third position is located between the first and second positions. The fourth position is located at a first distance below the cross-section where the inner flange node is located. The fifth position is located at a second distance above the bottom of the plurality of fastening plates 1. The sixth position is located between the fourth and fifth positions.

[0056] In this implementation scheme, the positions of the first set of fastening bands 3 and the second set of fastening bands 3 are symmetrical to the cross-section of the inner flange node. That is, the first position corresponds to the fourth position, the second position corresponds to the fifth position, and the third position corresponds to the sixth position. The first and fourth positions are located at the first distance above and below the cross-section of the inner flange node, the second and fifth positions are located at the second distance from the end of the fastening plate 1, the third position is located between the first and second positions, and the sixth position is located between the fourth and fifth positions. This structure ensures that the carbon fiber reinforced communication tower inner flange is evenly stressed, improves the stability of the carbon fiber reinforced communication tower inner flange, and thus improves the load-bearing capacity of the inner flange structure.

[0057] As an optional implementation, N fastening plates 1 are arranged in parallel to each other, and the interval between the N fastening plates 1 is greater than or equal to 10 mm.

[0058] In this embodiment, the N fastening plates 1 in the first fastener are arranged in a parallel manner, which makes the N fastening plates 1 in the first fastener uniformly stressed, thereby improving the overall load-bearing capacity of the method of reinforcing the inner flange of the communication tower with carbon fiber. In addition, the spacing between the N fastening plates 1 is greater than or equal to 10 mm. This spacing length ensures that the method of reinforcing the inner flange of the communication tower with carbon fiber is maintained in the most stable state, thereby improving the load-bearing capacity of the inner flange structure according to the embodiment of the present invention. It should be noted that the spacing between the N fastening plates should be greater than or equal to 10 mm, and the spacing between the N fastening plates should not be too large. It should be determined and set according to the actual size of the single-tube tower of the communication tower. The embodiment of the present invention does not limit this.

[0059] As an optional implementation, the M fastening bands 3 are multi-layered. In this implementation, the M fastening bands 3 can be multi-layered, for example: the fastening bands 3 can first be made of carbon fiber material, and then the carbon fiber fastening bands 3 are fixed by wrapping them around the fastening plates; the fastening bands 3 can also first be made of other flexible fastening materials, and then the fastening bands 3 are fixed by wrapping them around the fastening plates 1. In this way, the M fastening bands 3 can be multi-layered, and this structure improves the fastening effect of the M fastening bands 3 on the N fastening plates 1, thereby improving the load-bearing capacity of the inner flange structure.

[0060] In addition, the number of wrapping or pasting layers of the above M fastening straps can be set to three layers;

[0061] As an optional implementation, the first fastener is made of carbon fiber; the second fastener is also made of carbon fiber. In this embodiment, both the first and second fasteners can be made of carbon fiber. The selection of carbon fiber material depends on its advantages of low density and high strength. Compared to other materials, carbon fiber exhibits high tensile strength for the same mass. Furthermore, fasteners made of carbon fiber have a lower coefficient of thermal expansion, preventing deformation due to temperature and thus reducing the load-bearing capacity of the inner flange structure. Additionally, carbon fiber has strong corrosion resistance and anti-aging properties, extending the service life of the method for reinforcing the inner flange of a communication tower with carbon fiber. This embodiment of the invention can improve the load-bearing capacity of the inner flange structure.

[0062] This invention reinforces the inner flange node of a single-tube communication tower, improving the load-bearing capacity of the inner flange structure. The reinforcement device is installed at the inner flange node of the single-tube tower, with a first fastener and a second fastener at the node. The first fastener is fixed to the outside of the circular tube in the direction of the tube to improve its load-bearing capacity. The second fastener is fixed to the side of the first fastener facing the tube by wrapping and pasting, i.e., the second fastener binds the first fastener to the outside, further improving the tube's load-bearing capacity. Compared to existing methods for fastening inner flange nodes, this invention provides a more efficient fixation, solves the problem of insufficient strength in the bolts and stiffening plates of the inner flange node, and reduces the stress amplitude of the bolts at the inner flange node, thereby improving the load-bearing capacity of the inner flange structure.

[0063] like Figures 1-6 The illustrated device is a carbon fiber reinforcement device for a communication tower flange. The inner wall of the fastening band 3 is provided with several pressure rods 4. The fastening sleeve 2 has several cavities 5 inside. The outer wall of the fastening sleeve 2 has an inlet 6 on one side of each cavity 5 and an outlet 7 on the other side. A rotatably connected support cylinder 8 is provided on one side of the inner wall of each cavity 5. The outer wall of the support cylinder 8 has an annular guide groove 9 that matches the fastening band 3, and the inner side of the annular guide groove 9 has a connecting groove that matches the pressure rods 4. 10. A plurality of flexible pads 11 are provided on one side of the inner wall of the connecting groove 10; the top and bottom of the support cylinder 8 are symmetrically provided with support sleeves 14; the bottom and top of the inner wall of the cavity 5 are provided with annular sliding grooves that match the support sleeves 14; the inner wall of the cavity 5 is provided with a support shaft 15 inside the annular sliding groove; the inner wall of the support sleeve 14 is provided with a ratchet 17; the outer wall of the support shaft 15 is provided with an installation groove 18; the inner side of the installation groove 18 is rotatably provided with a pawl 16 that matches the ratchet 17; the pawl 16 is connected to the installation groove 18 by a torsion spring.

[0064] The inner wall of the cavity 5 is provided with a first guide roller 12 and a second guide roller 13 rotatably connected to one side of the support cylinder 8. The first guide roller 12 is located inside the cavity 5 near the inlet 6, and the second guide roller 13 is located inside the cavity 5 near the outlet 7. The first guide roller 12 provides rolling guidance for the fastening band 3 at the inlet 6, which can effectively enhance the smoothness and stability of the fastening band 3 entering the inlet 6. The second guide roller 13 provides rolling guidance for the fastening band 3 at the outlet 7, which can effectively enhance the smoothness and stability of the fastening band 3 exiting the outlet 7.

[0065] The distance between two adjacent pressure rods 4 is less than half the inner diameter of the pressure rod 4. The width of the fastening plate 1 is greater than twice the outer diameter of the pressure rod 4, and less than three times the outer diameter of the pressure rod 4. This ensures that multiple pressure rods 4 can simultaneously clamp and fix one fastening plate 1, thus enhancing the stability of the fastening plate 1. The number of cavities 5 is the same as the number of fastening straps 3, and the through-hole 6 is aligned with the fastening strap 3. This ensures that each cavity 5 corresponds to one fastening strap 3, facilitating the adjustment of the tightness of different fastening straps 3. This is applicable to situations where the outer diameter of the communication tower surface is different, further ensuring the adhesion and fixation between the fastening plate 1 and the communication tower surface.

[0066] The specific implementation method is as follows: In use, by setting up a fastening sleeve 2, pressure rod 4, cavity 5, support cylinder 8, connecting groove 10, pawl 16, and ratchet 17, when the fastening band 3 is an integral sheet material, the first fastener and the second fastener are directly placed on the outside of the inner flange connection of the communication tower. First, the fastening plate 1 of the first fastener is tightly and fixedly pasted to the surface of the communication tower. The second fastener is wrapped around the outside of the fastening plate 1. The fastening band 3 in the second fastener is inserted through the through-hole 6 of the fastening sleeve 2, and then the fastening band is tightened. 3. The fastening band 3 passes through the outlet 7 of the fastening sleeve 2 and moves along the annular guide groove 9 after entering the fastening sleeve 2. The pressure rod 4 moves with the fastening band 3. When the fastening band 3 is tightened, it enters through the inlet 6 and exits through the outlet 7. The pressure rod 4 moves along the annular guide groove 9 with the fastening band 3. When the pressure rod 4 moves to the inside of the annular guide groove 9, it inserts into the connecting groove 10. As the fastening band 3 continues to move, the pressure rod 4 continuously interacts with the connecting groove 10. The insertion and separation are quick and easy. During the tightening of the fastening band 3, the support cylinder 8 rotates counter-clockwise under the combined action of the pressure rod 4 and the connecting groove 10. As the support cylinder 8 rotates counter-clockwise, the support sleeve 14 rotates counter-clockwise along with it, and the ratchet 17 rotates counter-clockwise along with the support sleeve 14. Under the counter-clockwise rotation of the ratchet 17, the pawl 16 moves inward to the inside of the mounting groove 18, and simultaneously, the pawl 16 rebounds under the action of the torsion spring. Reset; the interaction between the pawl 16 and the ratchet 17 locks the clockwise rotation of the ratchet 17, which can effectively prevent the support cylinder 8 from rotating clockwise. At the same time, the pressure rod 4 limits the movement inside the connecting groove 10, which can effectively prevent the fastening band 3 from retracting after the position is locked, ensuring the fastening band 3's tightening and fixing effect.
