Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for power maintenance, in particular to a wire simulation frame for helicopter suspension method training. Background Technique

[0002] As a new operation and maintenance method, the safety and efficiency of helicopter live maintenance operations have been recognized, and more and more helicopter live maintenance operations are applied to the operation and maintenance work of transmission lines. With the increasing demand for helicopter live maintenance operations, the problem of talent cultivation has become increasingly prominent. Since the cultivation of helicopter live maintenance operation talents has not been perfected, the equipment required for training is even more scarce.

[0003] In order to train the personnel for live maintenance operations on transmission lines, the utility model patent CN215450518U, with the publication date of January 7, 2022, discloses a "simulation training device for maintenance operations", which simulates the bundled conductors of ultra-high voltage transmission lines on the ground, and conducts training by lowering a saddle-type hanging basket or personnel to the simulation frame. However, the simulated wire used in this simulation training device for maintenance operations is a straight steel pipe, which cannot simulate the actual bending state of the wire. The maintenance operation personnel still need to be further trained on the real transmission line cables for a long time, and it is impossible to train the helicopter suspension method maintenance operation personnel in one step. Summary of the Utility Model

[0004] In order to train the helicopter suspension method maintenance operation personnel more efficiently, the utility model provides a wire simulation frame for helicopter suspension method training. The topmost wire of the simulated wire in the wire simulation frame for helicopter suspension method training is a stranded wire, which can more realistically simulate the bundled conductors of ultra-high voltage transmission lines that bend downward, truly restore the state of the operation line, and conduct training by lowering a saddle-type hanging basket or personnel to the simulation frame, so that the maintenance operation personnel can adapt to the real situation of ultra-high voltage transmission lines faster and reduce the training time of the maintenance operation personnel.

[0037] For the convenience of understanding and description, the following description of the present utility model adopts absolute position relationships. Without special instructions, the orientation word "upper" represents Figure 1 the upper - side direction in Figure 1 the figure, the orientation word "lower" represents Figure 1 the lower - side direction in Figure 1 the figure, the orientation word "left" represents Figure 1 the left - hand side direction in Figure 1 the figure, the orientation word "right" represents

[0038] As Figures 1 to 2 shown, a conductor simulation frame for helicopter suspension method training described in an embodiment of the present utility model includes a left support, a simulated conductor 3, and a right support arranged in sequence from left to right. The left support includes an upper - left vertical plate 2 and a left base 1 connected up and down. The right support includes an upper - right vertical plate 4 and a right base 5 connected up and down. The left end of the simulated conductor 3 is connected to the upper - left vertical plate 2, and the right end of the simulated conductor 3 is connected to the upper - right vertical plate 4.

[0039] The simulated conductor 3 includes the uppermost conductor 31, and the uppermost conductor 31 is a stranded metal wire. For example, (real) aluminum conductor steel-reinforced wire can be used. The left end of the uppermost conductor 31 is sequentially connected to the upper left vertical plate 2 through the first left bolt column 33 and the first connection assembly 34. The first connection assembly 34 includes a first nut 341, a first gasket 342, a first spring 343, and a second gasket 344 that are sequentially connected from left to right. The left end of the uppermost conductor 31 is coaxially connected and fixed to the first left bolt column 33. The connection method of the right end of the uppermost conductor 31 to the upper right vertical plate 4 is the same as the connection method of the left end of the uppermost conductor 31 to the upper left vertical plate 2, that is, the structure on the left side of the wire simulation frame for helicopter suspension method training is the same as the structure on the right side and is a mirror image of each other.

[0040] Under the self-weight of the uppermost conductor 31, or, after being subjected to a downward pressure and the self-weight of the uppermost conductor 31. Along the left-right direction, the middle part of the uppermost conductor 31 can bend downward, and the first springs 343 on the left and right sides of the uppermost conductor 31 can both be compressed. The first spring 343 connected in series in the first connection assembly 34 can change the "cantilever beam" force structure to a "catenary of wire" force mode, reduce concentrated stress, and more realistically restore the on-line environment; at the same time, strong springs are connected in series at both ends of the wire to buffer the impact force of the hanging basket during landing.

[0041] The number of conductors of real high-voltage, extra-high-voltage or ultra-extra-high-voltage transmission lines can be four, six or eight. Correspondingly, the number of simulated conductors 3 in the wire simulation frame for helicopter suspension method training is four, six or eight. For example, in Figure 2 , the wire simulation frame for helicopter suspension method training only includes four simulated conductors 3 to simulate four bundled conductors. When the wire simulation frame for helicopter suspension method training includes six simulated conductors 3, it can simulate six bundled conductors. When the wire simulation frame for helicopter suspension method training includes eight simulated conductors 3, it can simulate eight bundled conductors.

[0042] When the number of simulated conductors 3 is four, the number of the uppermost conductors 31 is two, and the simulated conductor 3 further includes lower conductors 32, and the number of the lower conductors 32 is also two. As Figure 9 and Figure 10As shown, the lower conductor 32 is a steel pipe. The left end of the lower conductor 32 is sequentially connected to the upper left vertical plate 2 through the second left bolt column 35 and the second nut 36. The connection mode of the right end of the lower conductor 32 and the upper right vertical plate 4 is the same as that of the left end of the lower conductor 32 and the upper left vertical plate 2. Or, the left end of the lower conductor 32 is sequentially connected to the upper left vertical plate 2 through the first left bolt column 33 and the first connection assembly 34. The first connection assembly 34 includes a first nut 341, a first gasket 342, a first spring 343, and a second gasket 344 connected in sequence from left to right. The left end of the lower conductor 32 is coaxially connected and fixed to the first left bolt column 33. The connection mode of the right end of the lower conductor 32 and the upper right vertical plate 4 is the same as that of the left end of the lower conductor 32 and the upper left vertical plate 2. Under the self-weight of the lower conductor 32, or after being subjected to a downward pressure and the self-weight of the lower conductor 32, along the left-right direction, the lower conductor 32 can bend downward, and the first springs 343 on both the left and right sides of the lower conductor 32 can be compressed.

[0043] When the number of simulated conductors 3 is six or eight, there are two upper-layer conductors 31 and two lower-layer conductors 32. The simulated conductor 3 also includes middle-layer conductors, and the number of the middle-layer conductors is two or four. The upper-layer conductors 31 are metal stranded wires, and the lower-layer conductors 32 are metal stranded wires or steel pipes. The middle-layer conductors can be steel pipes. The left end of the middle-layer conductors is sequentially connected to the upper left vertical plate 2 through the second left bolt column 35 and the second nut 36. The connection mode of the right end of the middle-layer conductors and the upper right vertical plate 4 is the same as that of the left end of the middle-layer conductors and the upper left vertical plate 2. Or, the middle-layer conductors can also be metal stranded wires. The left end of the middle-layer conductors is sequentially connected to the upper left vertical plate 2 through the first left bolt column 33 and the first connection assembly 34. The first connection assembly 34 includes a first nut 341, a first gasket 342, a first spring 343, and a second gasket 344 connected in sequence from left to right. The left end of the middle-layer conductors is coaxially connected and fixed to the first left bolt column 33. The connection mode of the right end of the middle-layer conductors and the upper right vertical plate 4 is the same as that of the left end of the middle-layer conductors and the upper left vertical plate 2. After being subjected to a downward pressure and the self-weight of the middle-layer conductors, along the left-right direction, the middle-layer conductors can bend downward, and the first springs 343 on both the left and right sides of the middle-layer conductors can be compressed.

[0044] When the number of simulated conductors 3 is six or eight, both the middle-layer conductors and the lower-layer conductors 32 are steel pipes, or both the middle-layer conductors and the lower-layer conductors 32 are metal stranded wires, or the middle-layer conductors are metal stranded wires and the lower-layer conductors 32 are steel pipes. When all the simulated conductors 3 are metal stranded wires, the left base 1 and the right base 5 need to be connected and fixed to the ground through a connection structure (such as bolts).

[0045] When the simulated wire 3 is made of stranded metal wire, the left end of the simulated wire 3 is connected to the upper left vertical plate 2 through the first left bolt column 33 and the first connection assembly 34, and the right end of the simulated wire 3 is connected to the upper right vertical plate 4 through the first left bolt column 33 and the first connection assembly 34. When the simulated wire 3 is made of steel pipe, the left end of the simulated wire 3 is connected to the upper left vertical plate 2 through the second left bolt column 35 and the second nut 36, and the right end of the simulated wire 3 is connected to the upper right vertical plate 4 through the second left bolt column 35 and the second nut 36.

[0046] The left base 1 is of steel frame structure and extends in the front-back direction. The upper width of the left base 1 is smaller than the lower width of the left base 1. The left base 1 contains a plurality of base units 11 arranged at intervals in the front-back direction. The base units 11 are of steel frame structure. The left base 1 and the right base 5 are symmetrical about the left and right and are mirror images of each other. The left base 1 and the right base 5 are wide at the bottom and narrow at the top, and the whole has stability.

[0047] As Figure 3 shown, the base unit 11 is in a convex shape and is perpendicular to the front-back direction. The base unit 11 is made of welding the first square steel pipe 12. Two adjacent base units 11 are welded through the second square steel pipe 13. The second square steel pipe 13 extends in the front-back direction. The left base 1 and the right base 5 are made of square steel pipes, with good stability and light weight.

[0048] The upper end of the left base 1 is provided with a vertical plate groove 14 and a reinforcing plate 15. Both the vertical plate groove 14 and the reinforcing plate 15 extend in the front-back direction. The upper left vertical plate 2 is in an upright state and is parallel to the front-back direction. The lower end of the upper left vertical plate 2 is inserted into the vertical plate groove 14. A plurality of bolt installation through holes are arranged in the reinforcing plate 15. The lower part of the upper left vertical plate 2 and the reinforcing plate 15 are connected by bolts to ensure reliable connection.

[0049] The upper left vertical plate 2 is round at the top and square at the bottom. The upper left vertical plate 2 uses a 16-mm-thick steel plate. A plurality of simulated wire installation through holes are arranged on the upper left vertical plate 2, which can meet the simulation requirements of different splitting numbers and different wire spacings. For example, the plurality of simulated wire installation through holes include five styles, and the five styles are respectively: four first simulated four-split wire installation through holes 21, six second simulated six-split wire installation through holes 22, eight third simulated eight-split wire installation through holes 23, six fourth simulated six-split wire installation through holes 24, and eight fifth simulated eight-split wire installation through holes 25. The upper left vertical plate 2 and the upper right vertical plate 4 are symmetrical about the left and right and are mirror images of each other, as Figures 4 to 8 shown.

[0050] In use, the left and right ends of the four simulation wires 3 are inserted into the four first simulation quad-split wire installation through-holes 21 on the upper left vertical plate 2 and the upper right vertical plate 4 one by one to simulate the first quad-split wire; the left and right ends of the six simulation wires 3 are inserted into the six second simulation hex-split wire installation through-holes 22 on the upper left vertical plate 2 and the upper right vertical plate 4 one by one to simulate the second hex-split wire; the left and right ends of the eight simulation wires 3 are inserted into the eight third simulation octo-split wire installation through-holes 23 on the upper left vertical plate 2 and the upper right vertical plate 4 one by one to simulate the third octo-split wire; the left and right ends of the six simulation wires 3 are inserted into the six fourth simulation hex-split wire installation through-holes 24 on the upper left vertical plate 2 and the upper right vertical plate 4 one by one to simulate the fourth hex-split wire; the left and right ends of the eight simulation wires 3 are inserted into the eight fifth simulation octo-split wire installation through-holes 25 on the upper left vertical plate 2 and the upper right vertical plate 4 one by one to simulate the fifth octo-split wire.

[0051] For the convenience of installation, the multiple simulation wire installation through-holes are all in a gourd-shaped structure. The multiple simulation wire installation through-holes all include an upper through-hole and a lower through-hole that are connected (i.e., communicated) up and down, and the diameter of the upper through-hole is larger than that of the lower through-hole.

[0052] Specifically, the diameter of the lower through-hole of the first simulation quad-split wire installation through-hole 21 is 450 mm (4 * 450 mm), the diameter of the lower through-hole of the second simulation hex-split wire installation through-hole 22 is 400 mm (6 * 400 mm), the diameter of the lower through-hole of the third simulation octo-split wire installation through-hole 23 is 400 mm (8 * 400 mm), the diameter of the lower through-hole of the fourth simulation hex-split wire installation through-hole 24 is 500 mm (6 * 500 mm), and the diameter of the lower through-hole of the fifth simulation octo-split wire installation through-hole 25 is 550 mm (8 * 550 mm), as Figures 4 to 8 shown.

[0053] For the convenience of installation, the five styles are respectively marked with five different colors of paint. At the uppermost left installation hole of each wire style on the upper left vertical plate 2 and the upper right vertical plate 4, the style corresponding to the color is marked with a steel seal (e.g., 4 * 450 mm), and the sub-wire numbers are marked with a steel seal in a counterclockwise direction in sequence. Note that the markings are all on the outer side of the vertical plate. On the upper right vertical plate 4, the markings are made according to the symmetry principle with the upper left vertical plate 2 to keep the numbers of the simulation wire installation through-holes on the upper left vertical plate 2 and the upper right vertical plate 4 in one-to-one correspondence, so as to facilitate the operator to distinguish and install. The simulation wire installation through-holes are all in a gourd shape with a larger upper part and a smaller lower part. For the installation holes that are relatively close, the upper holes need to be tilted outward at a certain angle.

[0054] Multiple climbing weight-reducing through holes 26 are also provided on the upper left vertical plate 2 and the upper right vertical plate 4, and the multiple climbing weight-reducing through holes 26 are arranged in the vertical direction. The width of the climbing weight-reducing through hole 26 is 200 mm and the height is 150 mm for operators to climb. In addition, the middle parts of the upper left vertical plate 2 and the upper right vertical plate 4 are hollowed out to reduce the overall weight.

[0055] In this embodiment, as Figure 9 shown, the topmost layer of conductors 31 can be made of (real) aluminum conductor steel reinforced. The left end of the topmost layer of conductors 31 is sequentially connected to the upper left vertical plate 2 through the first left bolt column 33 and the first connection assembly 34. The first connection assembly 34 is located outside the left side of the upper left vertical plate 2. The left end of the topmost layer of conductors 31 is coaxially connected and fixed (such as crimped) to the first left bolt column 33, and the first left bolt column 33 passes through the simulated conductor installation through hole on the upper left vertical plate 2.

[0056] The first connection assembly 34 includes a first nut 341, a first gasket 342, a first spring 343, and a second gasket 344 connected in sequence from left to right. The second gasket 344 abuts against the upper left vertical plate 2. The first nut 341 is threadedly connected to the first left bolt column 33, and the first spring 343 is sleeved outside the first left bolt column 33. The connection mode of the right end of the topmost layer of conductors 31 to the upper right vertical plate 4 is the same as the connection mode of the left end of the topmost layer of conductors 31 to the upper left vertical plate 2.

[0057] As Figure 9 shown, the lower layer of conductors 32 is a steel pipe, which can play a good role in supporting and fixing to ensure the structural stability. The left end of the lower layer of conductors 32 is sequentially connected to the upper left vertical plate 2 through the second left bolt column 35 and the second nut 36. The left end of the lower layer of conductors 32 is welded to the second left bolt column 35. The second left bolt column 35 passes through the simulated conductor installation through hole on the upper left vertical plate 2, and the second nut 36 abuts against the upper left vertical plate 2. The second nut 36 is threadedly connected to the second left bolt column 35.

[0058] The connection mode of the right end of the lower layer of conductors 32 to the upper right vertical plate 4 is the same as the connection mode of the left end of the lower layer of conductors 32 to the upper left vertical plate 2. That is, the left and right structures of the conductor simulation frame for helicopter suspension method training are left-right symmetric and mirror images of each other.

[0059] The working process of the above-mentioned conductor simulation frame for helicopter suspension method training is introduced below.

[0060] The left base 1, the upper left vertical plate 2, the simulated conductors 3, the upper right vertical plate 4, and the right base 5 of the conductor simulation frame for helicopter suspension method training are detachably connected, and after disassembly, the left base 1, the upper left vertical plate 2, the simulated conductors 3, the upper right vertical plate 4, and the right base 5 can be transported to the training site by logistics.

[0061] Assemble it after arriving at the training site. According to the training needs, install different numbers of simulated conductors 3 to assemble the conductor simulation rack for helicopter suspension method training. The conductor simulation rack for helicopter suspension method training can be used for external suspension training such as helicopter sling method, hanging basket method, winch method, etc., and is used to simulate the on-line operation scenario. For example, the hanging basket can adopt a "Hanging Basket System for Helicopter Suspension Method Maintenance Operation" disclosed in Chinese Patent CN113300271A, with the publication date of August 24, 2021.

[0062] The conductor simulation rack for helicopter suspension method training is a conductor simulation rack for helicopter suspension method training, which can simulate the line operation environment, improve the training efficiency, and at the same time reduce the risk of injury to the trainees. The base is designed in a convex shape, which has stability. The main body is a hollow steel pipe, and a hollow structure is adopted to reduce the weight of the base.

[0063] According to the conductor layout method, different installation holes are set on the upper vertical plate to meet the training requirements of different conductor spacings. The installation holes are designed in a gourd shape for easy disassembly and assembly. The vertical plate uses a rounded rectangle hollowing, on the one hand, reducing the quality of the vertical plate, and on the other hand, it can be used for the operators to step on up and down, facilitating the up and down of the trainees for maintenance operations.

[0064] The upper-layer simulated conductors are made of real steel-core aluminum stranded wires. One end is crimped with a bolt column, and the other end is connected in series with gaskets, springs, gaskets, and nuts to realize the connection with the vertical plate of the simulation rack. Connecting the springs in series can change the "cantilever beam" force structure to the "conductor catenary" force mode, more realistically restoring the on-line environment; at the same time, strong springs are connected in series at both ends of the conductor to buffer the impact force of the hanging basket landing.
