Description

Technical Field

[0001] The invention belongs to the field of power transmission angle steel towers, and in particular relates to a reinforcement method and device suitable for complex nodes of power transmission towers. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] The transmission angle steel tower is the direct supporting structure of the overhead transmission line. Its safe and reliable operation is of great significance to ensure the safety and stability of the power grid. Some old transmission towers have the disadvantages of poor wind load bearing and anti-icing capabilities due to their low wind load bearing capacity. They are prone to overturning accidents when encountering extreme weather during service, posing a serious threat to the safety of the power grid. The tower types of transmission angle steel towers are complex and diverse, and the main material node structures are also diverse. In the past, the reinforced tower types were mainly 77 series old transmission angle steel towers such as 7725 and 7727, and their reinforcement parts were basically universal. However, at present, the 1B and 1A3 series tower types are also included in the scope of reinforcement. Only the 110kV transmission line 1B and 1A3 series straight towers involve multiple tower types and dozens of call heights. Compared with the 77 series structure, since the diagonal material is a large diagonal material connecting the two main materials, two diagonal materials are distributed on the inside and outside of the main material angle steel at the same node. The removal of the two inner diagonal materials for installation will have a great impact on the stability of the main material. Therefore, it is not allowed to remove any large diagonal material during installation. Therefore, when adopting the general reinforcement structure to affix the reinforcement member inside, obstacles will be encountered and it will not be able to pass through.

[0004] In summary, the current reinforcement method cannot meet the on-site requirements of complex nodes of transmission angle steel towers. In order to smoothly implement the project, a reinforcement method suitable for complex nodes of transmission towers is urgently needed to meet the requirements of complex nodes of transmission angle steel towers. Summary of the invention

[0005] In order to solve the technical problems existing in the above-mentioned background technology, the present invention provides a reinforcement method and device suitable for complex nodes of transmission towers, which meets the on-site reinforcement requirements of complex nodes of transmission angle steel towers.

[0006] In order to achieve the above object, the present invention adopts the following technical solution:

[0007] A first aspect of the present invention provides a reinforcement method applicable to complex nodes of transmission towers.

[0008] A reinforcement method applicable to complex nodes of transmission towers, comprising:

[0009] Acquire a node image of a transmission angle steel tower at a predetermined reinforcement position;

[0010] The node type in the transmission angle steel tower node image is identified by using a pre-trained node type recognition model; wherein the node type includes a first node type and a second node type; the first node type is: there are three angle steels and an original reinforcement plate on the inner side of the main material angle steel, the original reinforcement plate is fixed to two of the angle steels by bolts, and the other angle steel is located above the original reinforcement plate; the second node type is: two oppositely arranged oblique materials are connected to the inner side of the main material angle steel;

[0011] According to the identified node type, the matching reinforcement scheme is retrieved from the reinforcement scheme library and the corresponding reinforcement scheme is executed.

[0012] As an implementation method, when the node type is the first node type, the reinforcement scheme is:

[0013] Install a reinforcing plate next to the outer edge of the original reinforcing plate, and fix the reinforcing plate to the auxiliary material supporting it with bolts;

[0014] Cut the side of the original reinforcement plate close to the main limb angle steel parallel to the side edge;

[0015] Pass the end of the first part of the reinforcement member through the gap between the original reinforcement plate and the main limb angle steel formed after cutting, and continue to weld the second part of the reinforcement member to the end of the first part to form a complete reinforcement member;

[0016] The two ends of the complete reinforcement are arranged on both sides of the gap between the original reinforcement plate and the main limb angle steel, and are welded and fixed to the inner side of the main limb angle steel.

[0017] The advantage of the above technical solution is that, in order to be able to be fixedly installed at the first node type, the method of cutting one side of the original reinforcement plate and installing a reinforcing reinforcement plate on the other side is adopted, so that the end of the first part of the reinforcement passes through the gap between the original reinforcement plate and the main limb angle steel formed after cutting, while also ensuring the strength of the reinforcement plate.

[0018] As an implementation method, the design dimensions of the reinforcement plate are: the thickness of the reinforcement plate is the same as the thickness of the original reinforcement plate, the width of the reinforcement plate is half the width of the original reinforcement plate, and the length of the reinforcement plate covers the auxiliary materials on both sides.

[0019] The advantage of the above technical solution is that the reinforcing plate is used to compensate for the part of the original reinforcing plate that has been cut off, so as to ensure the stability of the entire complex transmission angle steel tower.

[0020] As an embodiment, the first part of the reinforcement is pre-welded from a first angle steel, a second angle steel and a connecting angle steel; wherein the second angle steel is integrally welded to the inner side of the first angle steel, and one end of the connecting angle steel is welded to the inner side of the second angle steel.

[0021] As an implementation manner, the second part of the reinforcement is composed of a third angle steel and a fourth angle steel, wherein the third angle steel is welded to the outer side of the other end of the connecting angle steel, and the third angle steel is completely overlap-welded to the inner side of the fourth angle steel.

[0022] The advantage of the above technical solution is that modular welding using reinforcements can better match the first node type scenario and improve the installation quality and efficiency of the reinforcements.

[0023] As an implementation mode, in the process of cutting the side of the original reinforcing plate close to the main limb angle steel parallel to the side edge, the screw holes in the original reinforcing plate are completely retained.

[0024] As an implementation method, when there is interference between the angle steel located above the original reinforcing plate and the reinforcement, one side edge of the angle steel located above the original reinforcing plate is cut into a rectangle of a set length and width parallel to the length direction, and then the cutting right angle is controlled to extend along a 60° angle.

[0025] The advantage of the above technical solution is that it can avoid interference between the reinforcement piece and the angle steel above the original reinforcement plate, thereby ensuring smooth fixation and installation of the reinforcement piece.

[0026] As an implementation method, when there is interference between the two angle steels connected to the original reinforcement plate and the reinforcement piece, the opposite sides of the two angle steels are cut parallel to the length direction into rectangles of set length and width, and then the cutting right angles are controlled to extend along an angle of 45°-60°.

[0027] As an implementation method, when the node type is the second node type, the reinforcement scheme is:

[0028] After the opposite sides of the two oppositely arranged oblique materials are cut parallel to the length direction into a rectangle of a set length and width, the cutting right angle is controlled to extend at an angle of 60° so that the reinforcement member can pass through the gap between the two oppositely arranged oblique materials;

[0029] The pre-welded complete reinforcement is welded at the second node type on the inner side of the node main material angle steel; wherein the reinforcement is composed of a first angle steel, a second angle steel, a connecting angle steel, a third angle steel and a fourth angle steel; the second angle steel is integrally welded on the inner side of the first angle steel, one end of the connecting angle steel is welded on the inner side of the second angle steel, the third angle steel is welded on the outer side of the other end of the connecting angle steel, and the third angle steel is completely overlapped and welded on the inner side of the fourth angle steel; the connecting angle steel is passed through the gap between two oppositely arranged oblique materials.

[0030] The advantage of the above technical solution is that it can ensure that there is no interference between the reinforcement piece and other diagonal materials, and the reinforcement piece can be installed stably and quickly.

[0031] A second aspect of the present invention provides a reinforcement device suitable for complex nodes of transmission towers.

[0032] A reinforcement device suitable for complex nodes of transmission towers, comprising:

[0033] A transmission angle steel tower node image acquisition module, which is used to acquire a transmission angle steel tower node image at a predetermined reinforcement position;

[0034] A transmission angle steel tower node type identification module is used to identify the node type in the transmission angle steel tower node image using a pre-trained node type identification model; wherein the node type includes a first node type and a second node type; the first node type is: there are three angle steels and an original reinforcement plate on the inner side of the main material angle steel, the original reinforcement plate is fixed to two of the angle steels by bolts, and the other angle steel is located above the original reinforcement plate; the second node type is: two oppositely arranged oblique materials are connected to the inner side of the main material angle steel;

[0035] The reinforcement scheme matching and retrieval module is used to retrieve the matching reinforcement scheme from the reinforcement scheme library according to the identified node type and execute the corresponding reinforcement scheme.

[0036] The beneficial effects of the present invention are:

[0037] The present invention provides a reinforcement method suitable for complex nodes of transmission towers, which solves the problem that the current reinforcement method cannot meet the on-site requirements of complex nodes of transmission angle steel towers. It uses a pre-trained node type recognition model to identify the node type in the transmission angle steel tower node image, and then according to the node type, retrieves the matching reinforcement plan from the reinforcement plan library and executes the corresponding reinforcement plan, thereby achieving the purpose of meeting the on-site reinforcement requirements of complex nodes of transmission angle steel towers.

[0053] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0054] It should be noted that the following detailed descriptions are all illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0055] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0056] Figure 1 FIG. 1 is a flow chart of a reinforcement method for complex nodes of a transmission tower according to an embodiment of the present invention. Figure 1 As shown, a reinforcement method applicable to complex nodes of a transmission tower according to an embodiment of the present invention comprises:

[0057] S101: Acquire a node image of a transmission angle steel tower at a predetermined reinforcement position.

[0058] In the specific implementation process, an image acquisition device (such as a camera) can be used to acquire the image of the transmission angle steel tower node at the predetermined reinforcement position.

[0059] The reinforcement position here can be determined by comparing the three-dimensional stress point cloud map of the complex transmission angle steel tower with the preset stress threshold.

[0060] In other embodiments, the reinforcement position may also be determined manually based on on-site experience.

[0061] S102: using a pre-trained node type recognition model to identify the node type in the transmission angle steel tower node image; wherein the node type includes a first node type and a second node type; the first node type is: there are three angle steels 3 and an original reinforcement plate 2 on the inner side of the main material angle steel 1, the original reinforcement plate 2 is fixed to two of the angle steels 3 by bolts, and the other angle steel 3 is located above the original reinforcement plate 2, such as Figure 2 As shown; the second node type is: the main material angle steel 1 is connected to the inside with two oppositely arranged diagonal materials 4, such as Figure 3 shown.

[0062] In step S102, the node type recognition model can be implemented using a deep learning model, or other existing neural network models, such as a convolutional neural network model.

[0063] The node type recognition model is trained using the training set and test set formed by the transmission angle steel tower node image samples and their pre-labeled node types.

[0064] S103: According to the identified node type, a matching reinforcement scheme is retrieved from a reinforcement scheme library and the corresponding reinforcement scheme is executed.

[0065] In the specific implementation process of step S103, if Figure 4 As shown in the figure, when the node type is the first node type, the reinforcement scheme is:

[0066] S10311: Install a reinforcing plate 5 on the outer edge of the original reinforcing plate 2, and fix the reinforcing plate 5 with the auxiliary material supporting it, such as Figure 6 As shown;

[0067] In this embodiment, the design dimensions of the reinforcement plate are: the thickness of the reinforcement plate is the same as the thickness of the original reinforcement plate, the width of the reinforcement plate is half the width of the original reinforcement plate, and the length of the reinforcement plate covers the auxiliary materials on both sides. Figure 5 As shown, the two ends of the reinforcement plate are also designed in a triangular shape, and threaded holes are designed at both ends and the middle setting position for passing bolts to fix the reinforcement plate to the corresponding auxiliary material. In this way, the reinforcement plate is used to compensate for the part of the original reinforcement plate that has been cut off to ensure the stability of the entire complex transmission angle steel tower.

[0068] S10312: Cut the side of the original reinforcement plate close to the main limb angle steel parallel to the side edge.

[0069] In a specific implementation process, the screw holes in the original reinforcement plate are completely retained during the process of cutting the side of the original reinforcement plate close to the main limb angle steel parallel to the side.

[0070] S10313: Pass the end of the first part of the reinforcement through the gap between the original reinforcement plate and the main limb angle steel formed after cutting, and continue to weld the second part of the reinforcement to the end of the first part to form a complete reinforcement.

[0071] Among them, Figure 7 As shown, the first part of the reinforcement is pre-welded by the first angle steel 6, the second angle steel 7 and the connecting angle steel 8; wherein the second angle steel 7 is integrally welded to the inner side of the first angle steel 6, and one end of the connecting angle steel 8 is welded to the inner side of the second angle steel 7. Figure 8 As shown, the second part of the reinforcement is composed of a third angle steel 9 and a fourth angle steel 10, wherein the third angle steel 9 is welded to the outside of the other end of the connecting angle steel 8, and the third angle steel 9 is completely overlapped and welded to the inside of the fourth angle steel 10. In this way, modular welding using reinforcements can better match the first node type scenario and improve the installation quality and efficiency of reinforcements. Fig. 9 and Fig.10 This is a schematic diagram of the complete reinforcement structure.

[0072] It should be noted here that when the original reinforcement plate is widened, it is best to make the connecting angle steel of the reinforcement member just pass through, and the edge width of the connecting angle steel should not exceed 3mm.

[0073] S10314: Place the two ends of the complete reinforcement on both sides of the gap between the original reinforcement plate and the main limb angle steel, and weld and fix them to the inner side of the main limb angle steel.

[0074] In order to be able to fix the installation at the first node type, the method of cutting one side of the original reinforcement plate and installing a reinforced reinforcement plate on the other side is adopted, so that the end of the first part of the reinforcement passes through the gap between the original reinforcement plate and the main limb angle steel formed after cutting, while also ensuring the strength of the reinforcement plate.

[0075] In other embodiments, when there is interference between the angle steel located above the original reinforcing plate and the reinforcing member, one side edge of the angle steel located above the original reinforcing plate is cut parallel to the length direction to form a rectangle of a set length and width, and then the right angle is controlled to extend at an angle of 60°. This can avoid interference between the reinforcing member and the angle steel above the original reinforcing plate, and ensure smooth fixation and installation of the reinforcing member.

[0076] like Fig.11 As shown, the remaining width L3 of the angle steel located above the original reinforcement plate after processing is 15mm, L2 is the side width of the bevel angle steel, and the straight side length L1 of the bevel angle steel after processing is suitable for the overlapped connecting angle steel to be installed in place. Usually, the intersection of the straight side and the bevel side should not exceed 2 / 3 of the side width of the connecting angle steel.

[0077] In some other embodiments, when there is interference between the two angle steels connected to the original reinforcing plate and the reinforcing member, the two opposite sides of the angle steels are cut parallel to the length direction to form a rectangle of a set length and width, and then the right angle of the cutting is controlled to extend at an angle of 45°-60°. Fig.11 The structures shown are the same.

[0078] It should be noted here that all angle steels and reinforcing plates are processed with electric machining tools, using plasma arc or laser cutting. When using plasma arc or laser cutting, the contaminated layer on the cut surface should be polished clean to reveal the metallic luster, and the cut surface should be smooth and flat. There should be no cracks on the cut surface and no edge defects greater than 1.0mm. The flatness of the cut surface at the cut-off point should not exceed 0.05t (t is the thickness of the angle steel) and should not exceed 2.0mm. The depth of the cut should not exceed 0.3mm, and the allowable deviation of the local notch depth is 1.0mm. When cutting the angle steel, no cutting opening is allowed at the intersection of the bevel and the straight edge. The diameter of the reinforcing plate and its hole on the angle steel is the bolt diameter at the corresponding position + 2mm, and the allowable diameter deviation is not more than 3mm.

[0079] All cut surfaces (including hole-making surfaces) shall be coated with cold-sprayed zinc coating according to the spray anti-corrosion quality requirements before installation. Before cold-spraying zinc, the weld surface of the main limb and tower foot, the damaged surface of the galvanized layer, and the dust, peeling, rust, oil stains on the steel surface shall be cleaned to reveal the metallic luster, and the surface cold-spraying zinc work shall be completed within 4 hours.

[0080] It is advisable to use cold spray zinc paint, and the zinc content of the paint film of cold spray zinc paint should also be ≥95%. Otherwise, cold spray zinc paint with a surface protective coating should be used.

[0081] The cold zinc spraying method should adopt gas (compressed air) spraying. The nozzle size and zinc spraying pressure should be selected according to the environmental conditions, the structural shape and size of the tower material.

[0082] The scope of cold zinc spraying includes: the main limb of the tower within the reinforcement range, the inclined auxiliary materials, cross materials, bolts within the main limb range, and the boot plate, rib plate, bottom plate and other steel surfaces of the tower foot. The operation sequence of zinc spraying is to spray from top to bottom, and the number of spraying passes is required to be no less than 3 times. The thickness of each zinc layer should be maintained at 40μm-50μm. The previous zinc layer paint film should be dry on the surface during the second spraying. In order to ensure the quality of the zinc layer on the surface of the weld, it is strictly forbidden to use the brushing process for zinc coating and anti-corrosion.

[0083] The appearance quality of cold-sprayed zinc layer should be smooth and flat, without any missing coating, sagging, impurities, cracks, peeling, blistering, shrinkage, convexity and concaveness, etc. The average thickness of the zinc layer should not be less than 120μm, and the minimum value should not be less than 100μm.

[0084] like Fig.12 As shown in the figure, when the node type is the second node type, the reinforcement scheme is:

[0085] S10321: After the opposite sides of the two oppositely arranged oblique materials are cut parallel to each other along the length direction into a rectangle of a set length and width, the cutting right angle is controlled to extend at an angle of 60° so that the reinforcement member can pass through the gap between the two oppositely arranged oblique materials;

[0086] S10322: Weld the pre-welded reinforcement to the second node type inside the main angle steel of the node; wherein the reinforcement is composed of the first angle steel, the second angle steel, the connecting angle steel, the third angle steel and the fourth angle steel, such as Fig. 9 As shown in the figure, the second angle steel is integrally welded to the inner side of the first angle steel, one end of the connecting angle steel is welded to the inner side of the second angle steel, the third angle steel is welded to the outer side of the other end of the connecting angle steel, and the third angle steel is completely overlapped and welded to the inner side of the fourth angle steel; the connecting angle steel is inserted into the gap between two oppositely arranged diagonal materials. This ensures that there is no interference between the reinforcement member and other diagonal materials, and the reinforcement member can be installed stably and quickly.

[0087] In this embodiment, the assembly gap between the reinforcement member and the original main limb angle steel is no more than 3 mm, and the difference in assembly gaps at the edges on both sides of the angle steel is no more than 1 mm.

[0088] In order to form a closed space between the reinforcement angle steel and the main limb angle steel, sealant is used to seal the exposed gaps on the surface between the reinforcement angle steel and the main limb angle steel, the inclined auxiliary material and the main limb angle steel, the reinforcement angle steel, etc.; the gaps formed by the main material joints, cross-plane nodes, and node overlaps are relatively large, and zinc plates, aluminum plates or other non-corrosive items can be used to fill the inside of the gaps, and the outside is sealed with sealant.

[0089] The sealant should be a neutral weather-resistant structural adhesive suitable for atmospheric environment. The grade of the structural adhesive should be a higher grade in GB / T22083 standard. The sealing surface should be smooth and flat and well connected with the weld. The height of the sealing angle should be consistent with the height of the welding angle. The length of the connection between the sealant and the weld should not exceed 10mm. The width of other sealant surfaces should not be less than the thickness of the steel. When the gap is large, it should not be less than the gap width. It is strictly forbidden to apply sealant on the weld surface or steel surface at will. Once it is stained, it should be cleaned up.

[0090] Sealing qualification standard: The sealant is combined with the angle steel and the weld end without cracks, pores or incomplete filling, and the appearance is smooth; the height is basically consistent with the fillet weld, and the height of the sealing angle at the overlap is not less than the end face of the sealing gap. The sealing quality should be checked 100%, and if the quality is found to be unqualified, the unqualified seal should be cleaned and resealed.

[0091] Assembly positioning can be done by fixtures, bolts, welds, etc., or by a combination of methods. The number and distribution of positioning should be selected according to the weight, length and assembly quality requirements of the assembled steel, and should be symmetrically distributed. When positioning is done by welds, all positioning welds should be arranged in the reinforced welds. The length of the positioning welds should not be less than 20mm. The positioning welds should be polished and inspected after welding. There should be no slag inclusions, pores and cracks on the weld surface.

[0092] Within the scope of the reinforcement of the entire main limb, except for the connecting angle steel, the connecting welds between the reinforcement angle steel and the main material of the main limb are arranged at the edges of the angle steel on both sides of the side width, forming longitudinal intermittent symmetrical fillet welds. From the upper and lower ends of the reinforcement range of each main limb, fillet welds of 200mm and above are symmetrically welded on both sides of the angle steel, and 200mm fillet welds are symmetrically welded when the interval in the middle is ≤500mm. The main material joints and cross-section joints should also be welded with longitudinal fillet welds of not less than 200mm from the cross section because the reinforcement angle steel has a cross section. However, transverse welds are not allowed to be welded between the cross section of the reinforcement angle steel and the main limb angle steel.

[0093] The welding method is SMAW, the welding material is E5003, the butt weld arc welding should use the electrode with a specification of Φ2.5mm, and the fillet weld should use the electrode with a specification of Φ3.2mm. The welding current is 100A-130A for Φ2.5mm electrode and 120A-150A for Φ3.2mm electrode.

[0094] The welding sequence is: first weld the butt weld, then weld the fillet weld. It is advisable to adopt multi-pass and multi-layer welding, and clean and self-check each pass and layer. The second pass can be welded only after passing the test. The thickness of each weld should not be greater than 6mm, and the joints of multi-layer welding should be staggered by 5mm or more. Each layer should be welded symmetrically, and it is strictly forbidden to weld the other side after all the welds on one side are completed. When welding, the arc should be struck in the welding area, and the molten pool should be filled when the arc is closed. It is strictly forbidden to test the current on the tower material.

[0095] In one or more embodiments, a reinforcement device suitable for complex nodes of a transmission tower is also provided, comprising:

[0096] A transmission angle steel tower node image acquisition module, which is used to acquire a transmission angle steel tower node image at a predetermined reinforcement position;
