Description

Technical Field

[0001] This invention relates to the field of power line construction crossing frames, and more particularly to an easy-to-install modular power line crossing frame. Background Technology

[0002] Currently, most power line crossing frame construction uses bamboo scaffolding. While bamboo and wood scaffolding is a backward technology strictly prohibited and phased out by the state, its widespread use has been concealed because power line crossing frames are temporary facilities and mostly located in the field, falling outside policy oversight. With the upgrading of safety risk management, the use of bamboo crossing frames, previously in a regulatory blind spot, has been restricted or phased out, and steel pipe scaffolding is being used as a substitute where conditions permit. However, steel pipe scaffolding used near live power lines is prone to insufficient safety distance during construction, potentially leading to electrical discharges or induced electric shocks and serious safety accidents. Furthermore, using bamboo or steel pipe crossing frames presents challenges in design and construction, including difficulty in calculating structural stress, inconvenient installation, low construction efficiency, and high labor costs. Summary of the Invention

[0003] The technical problem to be solved and the technical task proposed by this invention is to improve and refine existing technical solutions, and to provide an easy-to-install modular crossing frame for power lines, with the aim of improving construction efficiency and enhancing safety. To this end, this invention adopts the following technical solution.

[0004] A modular crossover frame for easy installation of power lines includes two single-sided uprights and guy wires for tensioning the uprights. Each single-sided upright includes two columns, four diagonal support rods, and one crossbeam. Each column includes a foundation foot, multiple standard segments, and one rotatable section. The foundation foot is used to connect and fix the column in a foundation pit. A vertical standard segment is bolted to the top of the foundation foot. A rotatable section is bolted to the top of the standard segment. Multiple standard segments are vertically connected in series on the top of the rotatable section. The column part on the rotatable section can be rotated to stand upright and flip over. The crossbeam includes multiple standard segments and two sliding square sleeves. The sliding square sleeves are fitted over the columns and can move vertically along the columns. Multiple standard segments are horizontally connected in series between two adjacent sliding square sleeves. One horizontal standard segment is set on the outside of each of the two sliding sections. The entire crossbeam can be moved vertically along the columns to the top and then connected and fixed with diagonal support rods. Each column is diagonally connected to the standard segments on both sides by one diagonal support rod.

[0005] When installing two columns, connect and fix one standard segment to the foundation foot in the pit for each column. Then, connect a rotatable section on top of the standard segment. Next, fit a sliding square sleeve onto the rotatable section and temporarily fix it. Then, according to design requirements, connect the required number of standard segments laterally on the sliding square sleeve to form a crossbeam. Then, rotate the rotatable part of the rotatable section 90 degrees outward and place it on the crossbeam. Then, connect multiple required number of standard segments laterally in series on the rotatable part of the rotatable section. After the connection is completed, rotate and erect the column. Then, tighten the rotatable part of the rotatable section to the lower part. By sliding the sliding square sleeve vertically, lift the crossbeam upward to the installation position. After connecting and securing the components, the diagonal support rods are installed to complete the installation of the single-sided upright. Once the upright is installed, the guy lines can be set up, and the sealing cables and netting can be installed. By using standard segments, flip-up segments, and sliding square sleeves, the crossing frame can be spliced ​​and assembled on-site. Crossing frames of different sizes and heights can be quickly assembled according to different crossing widths and heights. Each component can be mass-produced in the factory and transported to the site before assembly. They are connected by bolts, making assembly and disassembly convenient and construction fast. The crossing frame can be pre-assembled using 3D computer design, making it easy to calculate the overall cost and structural strength. It has good safety, and all components can be reused, effectively reducing labor costs.

[0006] As a preferred technical means, each standard segment of the crossbeam is connected to both ends with a tie plate. The tie plate is frame-shaped, and its upper end has a connection hole for connecting the sealing net cable. The tie plate is fastened to the standard segment by bolts. The tie plate facilitates the connection and arrangement of the sealing net cable and the ground anchor wire.

[0007] As a preferred technical approach: each column is equipped with a pulley assembly at its top. The pulley assembly includes two parallel and symmetrically arranged profiles, which are bolted to the top of the column. The two profiles extend horizontally towards the middle side of the crossbeam, and a fixed pulley for vertically lifting the crossbeam is bolted to the extended end. The crossbeam can be easily lifted using the fixed pulley.

[0008] As a preferred technical means: the reversible section includes a lower segment and an upper segment. The lower end of the lower segment is connected and fixed to the standard segment below by bolts, and the upper end of the upper segment is connected and fixed to the standard segment above by bolts. Both the lower and upper segments are provided with bolt connecting plates for connecting and fixing them together. The bottom of the upper segment and the top of the lower segment have rotatable connecting structures on the side facing the outside of the crossbeam. This effectively realizes the reversible section structure.

[0009] As a preferred technical approach, the reversible section, standard segment, and sliding square sleeve all adopt a frame structure, with the main body of the frame made of welded round tubes. Round tubes can be directly purchased from the market, resulting in relatively low cost. The frame structure is lightweight, low-cost, and provides good wind load resistance.

[0010] As a preferred technical means: a lateral pulley is provided on the inner side of each of the four corners at both the upper and lower ends of the slidable square sleeve. The lateral pulleys are arranged in a diagonally bisector direction, and the lateral pulleys are matched with the circular tubes of the flip-up section and the standard section to realize the vertical sliding structure of the slidable square sleeve. This effectively realizes the sliding structure of the slidable square sleeve.

[0011] As a preferred technical means: the slidable square sleeve includes four main vertical tubes located at the four corners. The upper and lower ends of each pair of adjacent main vertical tubes are connected by a main horizontal tube. Each main vertical tube has a vertical reinforcing tube on each side, with its upper and lower ends connected to the main horizontal tubes. A horizontal reinforcing tube is connected to the middle of the two vertical reinforcing tubes on the same side of the slidable square sleeve. Reinforcing connecting pieces are provided between the main vertical tubes and adjacent vertical reinforcing tubes. Lateral pulleys are located at the upper and lower ends of the main vertical tubes. A pull-wire connecting plate is provided on the lower middle side of the bottom main horizontal tube of the slidable square sleeve. This effectively achieves a reinforced slidable square sleeve structure, which, through its reinforced structure, can withstand a larger connection load.

[0012] As a preferred technical approach: The standard segment has triangular connecting plates on the inner sides of the four corners of its two end faces, with bolt holes on the triangular connecting plates; the slidable square sleeve has triangular connecting plates on the inner sides of the four corners of its four sides, with bolt holes on the triangular connecting plates; the flip-up segment has triangular connecting plates on the inner sides of the four corners of its upper and lower end faces, with bolt holes on the triangular connecting plates. This facilitates bolted connections between different components and allows for easy assembly and disassembly.

[0013] As a preferred technical means: the foundation foot includes a square base plate and four vertical plates arranged in a square on the base plate. Each vertical plate has multiple reinforcing ribs arranged at equal intervals on its outer side. The lower end of the standard segment on the foundation foot is embedded in the square groove in the middle of the four vertical plates and is connected to the foundation foot by bolts. The larger bottom area enhances the stability of the structure, and the reinforcing ribs can effectively enhance the structural strength.

[0014] As a preferred technical measure, the standard sections, sliding square sleeves, flip-up sections, and pull plates are all coated with a flame-retardant, heat-conducting, high-voltage-resistant, and insulating coating. This effectively addresses the safety risks associated with construction near live power lines.

[0015] As a preferred technical means: a guy wire connecting plate is provided between the two standard segments in the middle of the column. The guy wire connecting plate is a frame plate structure. A guy wire connecting hole is provided on the outer side of the middle of each side and at each corner. The guy wire connecting holes at the four corners are arranged diagonally and tilted outward and downward.

[0016] Beneficial effects: By using standard segments, reversible segments, and sliding square sleeves, crossing frames can be spliced ​​and erected on-site. Crossing frames of different sizes and heights can be quickly erected according to different crossing widths and heights. Each component can be mass-produced in the factory and transported to the site before erection. They are connected by bolts, making assembly and disassembly convenient and construction fast. The crossing frame can be pre-built using 3D computer design, making it easy to calculate the overall cost and structural strength. It has good safety. All components can be reused, which can effectively reduce labor costs. Furthermore, by spraying flame-retardant, heat-conducting, high-voltage resistant, and insulating coatings on the surface of standard segments, sliding square sleeves, reversible segments, and tie plates, the safety risks of construction near live lines can be effectively solved, ensuring good safety.

[0027] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] Example 1

[0029] like Figure 1 , 2 As shown, a modular crossing frame for easy installation of power lines is disclosed. The crossing frame includes two single-sided uprights 1 and guy wires 2 for tensioning the uprights. Each single-sided upright 1 includes two columns, four diagonal support rods 105, and one crossbeam. Each column includes a foundation foot 102, multiple standard segments 101, and one reversible section 103. The foundation foot 102 is used to connect and fix it in a foundation pit. A vertical standard segment 101 is bolted to the top of the foundation foot 102. A reversible section 103 is bolted to the top of the standard segment 101. Multiple standard segments 101 are vertically connected in series on the top of the reversible section 103. 01. The column part on the flip-up section 103 can be rotated to stand upright and flip over. The crossbeam includes multiple standard segments 101 and two sliding square sleeves 104. The sliding square sleeves 104 are fitted onto the column and can move vertically along the column. Multiple standard segments 101 are connected in a horizontal series between two adjacent sliding square sleeves 104. One horizontal standard segment 101 is set on the outside of each of the two sliding sections. The entire crossbeam can be moved vertically along the column to the top and then connected and fixed by diagonal support rods 105. One diagonal support rod 105 is diagonally connected between the upper part of each column and the standard segments 101 on both sides.

[0030] like Figure 7 , 8As shown, to facilitate the arrangement of the sealing net cable 3 and the ground anchor wire 2, each standard segment 101 of the crossbeam is connected to both ends with a tie plate 106. The tie plate 106 is frame-shaped, and its upper end has a connecting hole for connecting the sealing net cable 3. The tie plate 106 is fastened to the standard segment 101 by bolts. The tie plate 106 facilitates the connection and arrangement of the sealing net cable 3 and the ground anchor wire 2.

[0031] like Figure 8 As shown, for convenient lifting of the crossbeam, each column is equipped with a pulley assembly 107 at its top. The pulley assembly 107 includes two parallel and symmetrically arranged profiles 10701. The two profiles 10701 are bolted to the top of the column. The two profiles 10701 extend horizontally towards the middle side of the crossbeam, and a fixed pulley 10702 for vertical lifting of the crossbeam is bolted to the extended end. The fixed pulley 10702 facilitates the lifting of the crossbeam.

[0032] like Figure 5 As shown, to achieve the reversible section 103 structure, the reversible section 103 includes a lower section 10301 and an upper section 10302. The lower end of the lower section 10301 is connected and fixed to the standard section 101 below by bolts, and the upper end of the upper section 10302 is connected and fixed to the standard section 101 above by bolts. Both the lower section 10301 and the upper section 10302 are provided with bolt connecting plates 10303 for connecting and fixing the two. The bottom of the upper section 10302 and the top of the lower section 10301 are provided with rotatable connecting structures 10304 on the side facing the outside of the crossbeam. This effectively realizes the reversible section 103 structure.

[0033] like Figure 4-6 As shown, to achieve better wind load resistance, the reversible section 103, standard section 101, and sliding square sleeve 104 all adopt a frame structure, with the main body of the frame made of welded round tubes. Round tubes can be directly purchased from the market, resulting in relatively low costs. The frame structure is lightweight, low-cost, provides good wind load resistance, and offers high cost-effectiveness.

[0034] like Figure 6 As shown, to achieve a sliding structure, a lateral pulley 10401 is provided on the inner side of each of the four corners at both ends of the sliding square sleeve 104. The lateral pulleys 10401 are arranged along diagonal bisectors, and they cooperate with the circular tubes of the flip-up section 103 and the standard section 101 to realize the vertical sliding structure of the sliding square sleeve 104. This effectively realizes the sliding structure of the sliding square sleeve 104.

[0035] like Figure 6As shown, in order to achieve the enhanced sliding square sleeve 104 structure, the sliding square sleeve 104 includes four main vertical tubes 10402 located at the four corners. The upper and lower ends of two adjacent main vertical tubes 10402 are connected by a main horizontal tube 10403. Each main vertical tube 10402 has a vertical reinforcing tube 10404 on each side. The upper and lower ends of the vertical reinforcing tube 10404 are connected to the main horizontal tube 10403. A horizontal reinforcing tube 10405 is connected to the middle of the two vertical reinforcing tubes 10404 on the same side of the sliding square sleeve 104. A reinforcing connecting piece 10406 ​​is provided between the main vertical tube 10402 and the adjacent vertical reinforcing tube 10404. Lateral pulleys 10401 are provided at the upper and lower ends of the main vertical tube 10402. A pull wire connecting plate 10407 is provided on the lower middle side of the bottom main horizontal tube 10403 of the sliding square sleeve 104. The enhanced sliding square sleeve 104 structure effectively achieves the ability to withstand larger connection loads through the enhanced structure.

[0036] like Figure 4-6 As shown, to achieve bolted connections, triangular connecting plates 108 are provided on the inner sides of the four corners of the two end faces of the standard segment 101, and bolt holes are provided on the triangular connecting plates 108; triangular connecting plates 108 are provided on the inner sides of the four corners of the four sides of the sliding square sleeve 104, and bolt holes are provided on the triangular connecting plates 108; triangular connecting plates 108 are provided on the inner sides of the four corners of the upper and lower end faces of the flip-up segment 103, and bolt holes are provided on the triangular connecting plates 108. This allows for convenient bolted connections between different components and facilitates easy assembly and disassembly.

[0037] like Figure 3 As shown, to enhance structural strength, the foundation foot 102 includes a square base plate 10201 and four vertical plates 10202 arranged in a square on the base plate 10201. Each vertical plate 10202 has three equally spaced reinforcing ribs 10203 on its outer side. The lower end of the standard segment 101 on the foundation foot 102 is embedded in a square groove in the middle of the four vertical plates 10202 and is bolted to the foundation foot 102. The larger base area enhances structural stability, and the reinforcing ribs 10203 effectively increase structural strength.

[0038] To reduce construction safety risks, the standard section 101, the sliding square sleeve 104, the flip-up section 103, and the pull plate 106 are all coated with a flame-retardant, heat-conducting, high-voltage resistant, and insulating coating. This effectively addresses the safety risks associated with construction near live power lines, resulting in improved safety.

[0039] like Figure 9As shown, in order to facilitate the installation of the guy wire 2, a guy wire connecting plate is installed between the two standard segments 101 in the middle of the column. The guy wire connecting plate 109 is a frame plate structure. A guy wire connecting hole 10901 is provided on the outer side of the middle of each side and at each corner. The guy wire connecting hole 10901 at the four corners is set diagonally and tilts outward and downward.

[0040] During construction, the standard modules are transported to the site. A reinforced concrete foundation is installed in the pit, with anchor bolts pre-embedded. When installing the two columns, the foundation feet 102 are installed first. Then, one standard segment 101 is connected and fixed to the foundation feet 102 in the pit using anchor bolts. Next, a reversible segment 103 is connected above the standard segment 101. A sliding square sleeve 104 is then fitted onto the reversible segment 103 and temporarily fixed. According to design requirements, the required number of standard segments 101 are horizontally connected to the sliding square sleeve 104 to form a crossbeam. Then, the reversible part of the reversible segment 103 is rotated 90 degrees outwards and placed on the crossbeam. Finally, it is horizontally... The rotatable part of the rotatable section 103 is connected in series with multiple standard sections 101 of the required number, and a guy wire connecting plate 109 is set in the middle of the column. After the connection is completed, the column is flipped up and erected. Then the rotatable part of the rotatable section 103 is fastened to the lower part. The crossbeam is lifted to the installation position and connected and fastened by the vertical sliding of the sliding square sleeve 104. Finally, the diagonal support rod 105 is installed. The diagonal support rod 105 is connected to the bolt connecting plates 10303 set on the crossbeam and the column through the bolt connecting plates 10303 at both ends, thus completing the installation of the single-sided upright 1. After the upright is installed, the guy wires 2, the sealing net cable 3 and the sealing net can be set up.

[0041] By using standard segment 101, flip-up segment 103, and sliding square sleeve 104, the crossing frame can be spliced ​​and assembled on site. Crossing frames of different sizes and heights can be quickly assembled according to different crossing widths and heights. Each component can be mass-produced in the factory and transported to the site before construction. They are connected by bolts, making assembly and disassembly convenient and construction fast. The crossing frame can be pre-assembled using 3D design on a computer. The overall cost and structural strength are easy to calculate, and the safety is good. All components can be reused, which can effectively reduce labor costs.

[0042] In this example, the flame-retardant, thermally conductive, and high-voltage resistant insulating coating uses silicone material with a spray thickness of ≥1mm, achieving insulation performance up to ≥35kV voltage level.

[0043] In this example, the standard segment 101 that makes up the crossbeam has the same square cross-section as the standard segment 101 that makes up the column. The triangular connecting plates 108 on the four sides of the sliding square sleeve 104 are located at the corners where the main vertical pipe 10402 and the main horizontal pipe 10403 are connected. The cross-sectional dimensions of the standard segment 101 are 400mm*400mm, and the length of the standard segment 101 is 3012mm.

[0044] Depending on the actual span width and height requirements, the span frame can be structurally reinforced. One side of the span frame can be connected by multiple parallel single-sided uprights 1 through standard segments 101, or a lower horizontal reinforcing beam can be set between the uprights to enhance the structural strength. The horizontal reinforcing beam is formed by connecting standard segments 101 in series.

[0045] Example 2

[0046] Unlike the examples above, the standard segment 101 that forms the column adopts a square cross-section specification, and the standard segment 101 that forms the beam adopts a rectangular cross-section specification. The rectangular range size is equal to the rectangular range size formed by the two vertical reinforcing tubes 10404 and the two main horizontal tubes 10403 on the same side of the sliding square sleeve 104. The triangular connecting plates 108 on the four sides of the sliding square sleeve 104 are located at the four inner corners of the rectangle formed by the vertical reinforcing tubes 10404 and the main horizontal tubes 10403.

[0047] above Figure 1-9 The modular cross-pass frame for easy-to-install power lines shown is a specific embodiment of the present invention, demonstrating the outstanding substantive features and significant progress of the present invention. Based on the actual needs of use, equivalent modifications in shape, structure, etc., can be made to it according to the inspiration of the present invention, all of which are within the scope of protection of this solution.
