Modern industry's dependence on electricity has made power outage operations increasingly difficult, and the construction of live overhead crossings is inevitable.

[0003] At present, although the construction technology of load-bearing cable spanning frames and structural column spanning frames used for crossing voltage level lines of 35kV and above is mature, they are large in size, take a long time to set up, have complex assembly process and high cost. Due to the restrictions of terrain conditions, they are not suitable for crossing live 10kV transmission line construction. Therefore, the current construction of live 10kV transmission line crossing generally adopts bamboo, wooden poles or steel pipe scaffolding and other materials to build temporary spanning frames to provide support and protection for the transmission line under construction. However, the construction of spanning frames is not only labor-intensive, inefficient, and has poor maneuverability and safety, but also troublesome to dismantle and transport in the later stage, requiring a lot of manpower and material resources, which is very inconvenient.

DETAILED DESCRIPTION

[0032] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following is a brief introduction to the drawings required for use in the embodiments. Obviously, the drawings described below are some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0033] Please see Figure 1 and Figure 2 The embodiment of the present invention provides a winding-type high-altitude cross-line sealing net mobile work vehicle for transmission line crossing construction, including a main work vehicle 10, an auxiliary work vehicle 20, a cross-line sealing net winding and releasing mechanism 50 and a receiving and locking net mechanism 60. The upper end of the main work vehicle 10 is provided with a main lifting frame 30 that can be freely raised and lowered, and the upper end of the auxiliary work vehicle 20 is provided with an auxiliary lifting frame 40 that can be freely raised and lowered. The cross-line sealing net winding and releasing mechanism 50 is laterally arranged on the upper end of the main lifting frame 30, and the receiving and locking net mechanism 60 is laterally arranged on the upper end of the auxiliary lifting frame 40. The main work vehicle 10 and the auxiliary work vehicle 20 are crawler or wheeled motor vehicles. When in use, the main work vehicle 10 and the auxiliary work vehicle 20 can be freely moved to the opposite sides below the transmission line that needs to be crossed for construction, and the cross-line sealing net winding and releasing mechanism can be respectively released by the main lifting frame 30 and the auxiliary lifting frame 40. 50 and the receiving and locking net mechanism 60 rise to both sides above the transmission line that needs to be crossed over for construction, so that the cross-line sealing net winding and releasing mechanism 50 and the receiving and locking net mechanism 60 are relative and parallel to each other, and a protective net 70 and a supporting air curtain 80 are wound on the cross-line sealing net winding and releasing mechanism 50. The cross-line sealing net winding and releasing mechanism 50 can release the protective net 70 and the supporting air curtain 80 from the upper direction of the transmission line to be crossed over for construction toward the receiving and locking net mechanism 60, and can inflate the supporting air curtain 80 to provide supporting force for the supporting air curtain 80, so as to carry the protective net 70 from above the transmission line to be crossed over for construction toward the receiving and locking net mechanism 60. The receiving and locking net mechanism 60 can receive and lock the released protective net 70 and the supporting air curtain 80, and combine with them to form a sealing net protection above the transmission line.

[0034] Please see Figure 2 、 Figure 4 、 Figure 5 and Figure 8Specifically, the cross-line sealing net winding and releasing mechanism 50 includes a sealing net releasing frame 51, a sealing net winding roller 52, an air curtain winding roller 53, a first driving device 54, an auxiliary transmission mechanism 55 and an inflation device 56 arranged on the sealing net releasing frame 51. The sealing net releasing frame 51 is horizontally arranged at the upper end of the main lifting frame 30, and the sealing net winding roller 52 and the air curtain winding roller 53 are respectively horizontally arranged in the sealing net releasing frame 51 and can rotate freely, and the sealing net winding roller 52 is arranged close to the top of the air curtain winding roller 53, the sealing net winding roller 52 and the air curtain winding roller 53 are parallel to each other and the axial ends are aligned, the auxiliary transmission mechanism 55 is horizontally arranged on the side of the sealing net releasing frame 51 facing the receiving locking net mechanism 60, and is opposite to the air curtain winding roller 53, the protective net 70 is wound on the sealing net winding roller 52, and the supporting air curtain 80 is wound on the air curtain winding roller 53. The release end passes through the auxiliary transmission mechanism 55 and is fixedly connected to the release end of the protective net 70. An inflation port 81 is provided at the release end of the support air curtain 80. The air supply end of the inflation device 56 is connected to the inflation port 81 to inflate or exhaust the released support air curtain 80. The first driving device 54 is respectively connected to the sealing net winding roller 52 and the air curtain winding roller 53 axis, and can respectively drive the sealing net winding roller 52 and the air curtain winding roller 53 to rotate, so as to synchronously and at the same speed wind up or release the protective net 70 and the support air curtain 80. The auxiliary transmission mechanism 55 can assist the air curtain winding roller 53 in releasing or winding up the support air curtain 80 in the direction of the receiving locking net mechanism 60, and can support the support air curtain 80 so that the released support air curtain 80 can carry the released protective net 70 to extend across the power transmission line in the direction of the receiving locking net mechanism 60 after inflation.

[0035] The auxiliary transmission mechanism 55 includes two freely rotatable squeezing rollers 551, a transmission motor 552 and a support plate 553. The two squeezing rollers 551 are arranged horizontally, one above and one below, on the side of the sealing net release frame 51 facing the receiving locking net mechanism 60, and are parallel to each other and aligned at both ends with the air curtain winding roller 53. The two squeezing rollers 551 are close to each other, and a clamping channel is formed between the two squeezing rollers 551. The support plate 553 is a long strip plate body, which is arranged parallel to the sealing net release frame 51 and is located on the side of the clamping channel facing the receiving locking net mechanism 60. On the side, the support plate 553 is arranged parallel to the squeezing roller 551. After the release end of the support air curtain 80 passes through the clamping channel, it is fixedly connected to the release end of the protective net 70, and the support air curtain 80 is placed parallel to the upper end surface of the support plate 553. The support plate 553 provides support force for the support air curtain 80 output from the clamping channel; the two squeezing rollers 551 are preferably rubber rollers, which squeeze the support air curtain 80 against each other, so that the inside of the squeezed part of the support air curtain 80 is sealed, so that the gas inflated in the support air curtain 80 is maintained at its release end.

[0036] In this embodiment, one of the squeezing rollers 551 serves as an active roller, and the other squeezing roller 551 serves as a driven roller. The output shaft end of the transmission motor 552 is axially connected to the active roller to drive the active roller to rotate. The friction force of the active roller and the driven roller squeezing each other drives the driven roller and the active roller to rotate in opposite directions, thereby realizing squeezing and conveying the support air curtain 80. The transmission motor 552 is a servo motor. The rotation direction and rotation speed of the transmission motor 552 match the speed of the first drive device 54 for releasing or winding the support air curtain 80, so as to assist the air curtain winding roller 53 in releasing or winding and collecting the support air curtain 80 toward the receiving locking net mechanism 60.

[0037] Please continue to see Figure 5 Furthermore, spring seats 554 are respectively provided at the two axial ends of the driven roller, and the spring seats 554 are correspondingly fixed on the sealing net release frame 51, and are rotatably connected to the two axial ends of the driven roller for supporting the driven roller, pressing the driven roller toward the active roller through the spring seat 554, and elastically buffering the extrusion force between the driven roller and the active roller through the spring seat 554, so that the support air curtain 80 can pass between the two extrusion rollers 551, and the extrusion force applied by the spring seat 554 to the driven roller is greater than the inflation pressure in the support air curtain 80, so as to ensure that the interior of the support air curtain 80 is sealed at the squeezed part, so that the inflated gas in the support air curtain 80 is maintained at its release end, so that the air curtain winding roller 53 can smoothly release or reel in the support air curtain 80.

[0038] Please see Figure 2When carrying out the cross-line sealing net operation, the main operation vehicle 10 and the auxiliary operation vehicle 20 can be freely moved to the two opposite sides below the transmission line that needs to be crossed for construction, and the cross-line sealing net winding and releasing mechanism 50 and the receiving and locking net mechanism 60 are raised to the top of the two sides of the transmission line that needs to be crossed for construction by the main lifting frame 30 and the auxiliary lifting frame 40 respectively. Then, the sealing net winding roller 52 and the air curtain winding roller 53 are driven by the first driving device 54 to release the protective net 70 and the supporting air curtain 80 synchronously and at the same speed. The transmission motor 552 synchronously drives the squeezing roller 551 to rotate, and transports the supporting air curtain 80 released by the air curtain winding roller 53 toward the receiving and locking net mechanism 60. At the same time, the inflation device 56 pushes the released supporting air curtain 80 toward the receiving and locking net mechanism 60. The air curtain 80 is inflated to expand. During the release of the air curtain 80 and the protective net 70, the inflation device 56 continues to inflate the air curtain 80, and the release speed of the air curtain 80 matches the inflation pressure, so that the air curtain 80 always remains in an expanded state during the release process. The supporting force formed by the air curtain 80 after expansion is used to carry the released protective net 70 along the support plate 553 toward the receiving and locking net mechanism 60 to extend across the power transmission line. The receiving and locking net mechanism 60 can receive and lock the end of the protective net 70 or the air curtain 80 extending across the power transmission line, and combine with each other to form a sealing net protection above the power transmission line.

[0039] When the supporting air curtain 80 and the protective net 70 are being wound and collected, after the receiving locking net mechanism 60 releases the lock on the release end of the protective net 70 or the supporting air curtain 80, the first driving device 54 drives the sealing net winding roller 52 and the air curtain winding roller 53 to rotate in the opposite direction to collect the supporting air curtain 80 and the protective net 70, and the conveying motor 552 synchronously drives the squeezing roller 551 to rotate in the opposite direction to transport the supporting air curtain 80 toward the air curtain winding roller 53. At the same time, the inflation device 56 exhausts and depressurizes the supporting air curtain 80. During the process of collecting the supporting air curtain 80 and the protective net 70, the inflation device 56 continues to exhaust and depressurize the supporting air curtain 80, and the exhaust and depressurization speed of the supporting air curtain 80 needs to match its winding and collecting speed, so that the release end of the supporting air curtain 80 always remains in an expanded and supported state during the collection process to prevent the supporting air curtain 80 from falling on the transmission line after sudden decompression.

[0040] The inflation device 56 includes an air compressor, an air supply hose and an air pressure control mechanism. The air compressor is arranged on the sealing net release frame 51 or the carrying mechanism. The air pressure control mechanism is arranged at the gas output end of the air compressor. One end of the air supply hose is connected to the inflation port 81 of the supporting air curtain 80, and the other end of the air supply hose is connected to the air pressure control mechanism. The middle part of the air supply hose is arranged along the edge of the supporting air curtain 80 or the protective net 70. The air pressure control mechanism includes an air pressure controller, an inflation solenoid valve, an exhaust solenoid valve and a pressure sensor. The inflation solenoid valve and the exhaust solenoid valve are installed at the gas output end of the air compressor through a three-way pipe and are connected to the air supply hose. The pressure sensor is arranged in the inflation port 81 of the supporting air curtain 80 or on the air inlet of the air supply hose. The inflation solenoid valve, the exhaust solenoid valve and the pressure sensor are electrically connected to the air pressure controller respectively. When the supporting air curtain 80 is released, the air compressor and the inflation solenoid valve are opened by the air pressure controller. , and controls the exhaust solenoid valve to close, and fills the support air curtain 80 with compressed air; when the support air curtain 80 is being collected, the air pressure controller controls the air compressor and the charging solenoid valve to close, and controls the exhaust solenoid valve to open, so as to exhaust and relieve the pressure of the support air curtain 80; during the process of inflating or exhausting the support air curtain 80, the air pressure controller uses the pressure sensor to monitor the pressure inside the support air curtain 80, and when the pressure reaches a preset pressure value, controls the opening of the charging solenoid valve and the exhaust solenoid valve to control the inflation pressure or exhaust pressure of the support air curtain 80. For example, during the inflation process, when the air pressure inside the support air curtain 80 is lower than the preset pressure value, the air pressure controller controls the opening of the charging solenoid valve to increase to increase the inflation flow rate; during the exhaust process, when the air pressure inside the support air curtain 80 is higher than the preset pressure value, the air pressure controller controls the opening of the exhaust solenoid valve to increase to increase the exhaust flow rate.

[0041] Please see Figure 2 、 Figure 9 、 Figure 10 and Figure 11The support plate 62 is fixed in the slide 65 on the side of the support frame 61, and the other side of the support plate 62 extends parallel to the direction of the release frame 51, and is used to receive the end of the air curtain 80 released by the air curtain 80. The plurality of locking net hooks 64 are fixedly arranged at intervals along the length direction of the support frame 61 on the end surface of the support frame 61 facing the release frame 51, and are located just above the support plate 62. The open end of each locking net hook 64 is opened downward, and the opening of the locking net hook 64 The mouth end is V-shaped or trumpet-shaped, and the height is consistent. The lifting drive 63 is a pneumatic cylinder or a screw lifter, which is vertically arranged on one side of the slide 65. The driving end of the lifting drive 63 is connected to the seat 66 of the receiving plate 62 that is stuck in the slide 65. The lifting drive 63 is powered by an air compressor or an external power supply, which can drive the receiving plate 62 to move up and down along the slide 65 toward the locking net hook 64. The released end of the protective net 70 is laterally fixed with a connecting column 71 that matches the locking net hook 64. When in use, when the released end of the supporting air curtain 80 extends to the upper end surface of the receiving plate 62, the lifting drive 63 can drive the receiving plate 62 to rise, and use the receiving plate 62 to support the end of the supporting air curtain 80 and push it toward the locking net hook 64, so that the connecting column 71 set at the end of the protective net 70 is stuck in the locking net hook 64 to achieve locking of the supporting air curtain 80 and the protective net 70.

[0042] In the above embodiment, the first driving device includes two servo motors, and the two servo motors are axially connected to the net sealing winding roller 52 and the air curtain winding roller 53 respectively. The rotational speeds of the two servo motors are matched, and they can respectively drive the net sealing winding roller 52 and the air curtain winding roller 53 to rotate, so as to synchronously and at the same speed wind up or release the protective net 70 and support the air curtain 80.

[0043] Please see Figure 6 and Figure 7The protective net 70 is a lightweight nylon net; the supporting air curtain 80 is composed of a plurality of long columnar air bags made of polyethylene material arranged in parallel, and the length direction of each air bag is oriented toward the receiving locking net mechanism 60. The above-mentioned inflation port 81 is provided at the end of each air bag oriented toward the receiving locking net mechanism 60. The inflation port 81 of each air bag is interconnected with the air supply hose of the inflation device 56 in a series or parallel manner, and the air bags are inflated synchronously through the inflation device 56. The long columnar air bags can increase the lateral support force of the supporting air curtain 80 and reduce the sag. After the supporting air curtain 80 and the protective net 70 are released, the protective net 70 is laid flat on the upper surface of the supporting air curtain 80. The use of the protective net 70 can increase the connection strength between the sealing net release frame 51 and the receiving frame 61.

[0044] When the above embodiment is implemented, as the release ends of the supporting air curtain 80 and the protective net 70 increase in extension distance, they will sag under the action of gravity and be lower than the sealing net release frame 51. Therefore, the rising height of the receiving and locking net mechanism 60 needs to be lower than the height of the sealing net release frame 51 and correspond to the height of the release end of the supporting air curtain 80 after extension. In this way, the receiving and locking net mechanism 60 can smoothly receive and lock the protective net 70 and the supporting air curtain 80.

[0045] After the receiving and locking net mechanism 60 receives and locks the protective net 70 and the supporting air curtain 80, the height of the receiving and locking net mechanism 60 remains unchanged, so that the protective net 70 and the supporting air curtain 80 are tilted above the power transmission line. Furthermore, the air pressure in the supporting air curtain 80 is required to continuously maintain a predetermined pressure. Thus, after the receiving and locking net mechanism 60 unlocks the protective net 70 and the supporting air curtain 80, the height of the release end of the supporting air curtain 80 can remain stable. Furthermore, the tilted protective net 70 and the supporting air curtain 80 above the power transmission line also serve to guide or direct falling objects. For example, when falling objects fall onto the protective net 70, the tilted protective net 70 and the supporting air curtain 80 can guide the falling objects toward the edge of the receiving and locking net mechanism 60, facilitating the discharge of the falling objects while also reducing the pressure exerted by the falling objects on the protective net 70 and the supporting air curtain 80.

[0046] In addition, it should be noted that, when the above embodiment is implemented, it is necessary to operate under no wind or light wind conditions to ensure the stability of the protective net 70 and the supporting air curtain 80 during the release process.

[0047] Please see again Figure 1Furthermore, in order to improve the convenience of the locking net mechanism 60 in receiving the protective net 70 and the supporting air curtain 80, the cross-line sealing net winding and releasing mechanism 50 also includes an angle adjustment cylinder 31. One side of the sealing net releasing frame 51 is pin-connected to the upper end of the main lifting frame 30. The telescopic end of the angle adjustment cylinder 31 is pin-connected to the other side of the sealing net releasing frame 51. The fixed end of the angle adjustment cylinder 31 is pin-connected to the upper end of the main lifting frame 30. The angle adjustment cylinder 31 is a pneumatic cylinder powered by an air compressor. The cylinder 31 can push the net sealing release frame 51 to flip up and down toward the receiving locking net mechanism 60 to adjust the direction in which the net sealing release frame 51 releases the supporting air curtain 80. For example, when the supporting air curtain 80 is extended a large distance, the release end of the supporting air curtain 80 will sag under the action of gravity. When the sag is too large, the net sealing release frame 51 can be flipped upward by adjusting the angle of the cylinder 31, so that the release end of the supporting air curtain 80 is tilted upward, thereby increasing the height of the release end of the supporting air curtain 80 so that the receiving locking net mechanism 60 can receive the release end of the supporting air curtain 80.

[0048] Please see Figure 2 and Figure 12 Furthermore, to improve the stability of the main vehicle 10 and the auxiliary vehicle 20, hydraulic leveling legs 11 are installed at the four corners of the main vehicle 10 and the auxiliary vehicle 20. A hydraulic station 15 is also installed on each of the main vehicle 10 and the auxiliary vehicle 20. Each hydraulic leveling leg 11 can extend outward from the vehicle body to level and support the main vehicle 10 or the auxiliary vehicle 20. The hydraulic leveling legs 11 can achieve the function of supporting the vehicle body stably through the hydraulic station 15.

[0049] Please see Figure 2 、 Figure 12 、 Figure 13 and Figure 14 Furthermore, in order to improve the adaptability of the main work vehicle 10 and the auxiliary work vehicle 20 in field operations, auxiliary support mechanisms 12 are respectively provided at the four corners of the main work vehicle 10 and the auxiliary work vehicle 20. The auxiliary support mechanisms 12 are arranged adjacent to the hydraulic leveling legs 11. Each of the auxiliary support mechanisms 12 can be drilled into the soil on one side of the hydraulic leveling legs 11 to assist the hydraulic leveling legs 11 in providing lateral support force to the main work vehicle 10 or the auxiliary work vehicle 20.

[0050] Specifically, each of the auxiliary support mechanisms 12 includes an auxiliary support arm 121, a main hydraulic arm 122, a secondary hydraulic arm 123, a mounting seat 124, a rotating frame 125, a drill rod driver 126 and a drill rod 127. The mounting seat 124 is fixedly mounted on the vehicle body. One end of the auxiliary support arm 121 is pinned to the lower end of the mounting seat 124, and the other end thereof extends toward the outside of the vehicle body. One end of the main hydraulic arm 122 is pinned to the upper end of the mounting seat 124, and the other end thereof is pinned to the auxiliary support arm 121. The upper end of the rotating frame 125 is pinned to the lower side of the end of the auxiliary support arm 121 away from the mounting seat 124, and one end of the auxiliary hydraulic arm 123 is pinned to the lower side of the end of the auxiliary support arm 121 close to the mounting seat 124, and the other end is pinned to the lower end of the rotating frame 125. The drill rod driver 126 is installed on the rotating frame 125, and the output shaft of the drill rod driver 126 is vertically downward. The drill rod 127 is vertically installed at the output shaft end of the drill rod driver 126. The main hydraulic arm 122 and the auxiliary hydraulic arm 123 are powered by the hydraulic station 15. The drill rod driver 126 is a hydraulic motor powered by the hydraulic station 15. The main hydraulic arm 122 is powered by the hydraulic station 15 to drive the auxiliary support arm 121 to retract and fold above the vehicle body or extend toward the outside of the vehicle body. The auxiliary hydraulic arm 123 can drive the lower end of the rotating frame 125 to rotate toward the mounting seat 124 to fold the drill rod 127 or drive the lower end of the rotating frame 125 to rotate toward the mounting seat 124. The seat 124 is rotated in the outer direction to extend the drill rod 127 so that the drill rod 127 is close to the ground. For example, when the main working vehicle 10 and the auxiliary working vehicle 20 are working on relatively soft ground in the field, the hydraulic leveling legs 11 are likely to sink into the soil. At this time, the drill rod 127 can be driven into the soil by the drill rod driver 126, and the drill rod 127 is used to assist the hydraulic leveling legs 11 in providing lateral support to the main working vehicle 10 or the auxiliary working vehicle 20, so as to improve the body stability of the main working vehicle 10 or the auxiliary working vehicle 20.

[0051] In the above embodiment, the main lifting frame 30 and the auxiliary lifting frame 40 are preferably hydraulic lifting arms, which are powered by the hydraulic stations 15 on the main working vehicle 10 and the auxiliary working vehicle 20 respectively.

[0052] Please see Figure 2Furthermore, in order to facilitate the storage of the main lifting frame 30 and the auxiliary lifting frame 40 and reduce the height space occupied by the main lifting frame 30 and the auxiliary lifting frame 40, in the above embodiment, the main lifting frame 30 and the auxiliary lifting frame 40 are respectively folded. The specific arrangement is as follows: a main support 13 is horizontally provided at the upper end of the main working vehicle 10, the lower end of the main lifting frame 30 is pin-connected to one end of the main support 13, and a first hydraulic cylinder 14 is pin-connected to the other end of the main support 13, and the telescopic end of the first hydraulic cylinder 14 is pin-connected to the side wall of the main lifting frame 30; a secondary support 21 is provided at the upper end of the auxiliary working vehicle 20, the auxiliary lifting frame 40 is pin-connected to one end of the secondary support 21, and a second hydraulic cylinder 22 is pin-connected to the other end of the secondary support 21, and the telescopic end of the second hydraulic cylinder 22 is pin-connected to the side wall of the auxiliary lifting frame 40. During cross-line operations, the first hydraulic cylinder 14 and the second hydraulic cylinder 22 can respectively support the main lifting frame 30 and the auxiliary lifting frame 40, so that the main lifting frame 30 and the auxiliary lifting frame 40 can be erected on the main support 13 and the auxiliary support 21, respectively. When the cross-line operation is completed, the first hydraulic cylinder 14 and the second hydraulic cylinder 22 can be operated to retract, so that the main lifting frame 30 and the auxiliary lifting frame 40 can be folded to one side, respectively, to reduce the height of the main lifting frame 30 and the auxiliary lifting frame 40.

[0053] Please see Figure 4 、 Figure 9 and Figure 15 In a preferred embodiment, the two ends of the net sealing release frame 51 and the receiving frame 61 are respectively provided with a first connecting head 91 and a second connecting head 92 that match each other. The net sealing release frame 51 and the receiving frame 61 can be expanded laterally in parallel along their length direction, and are locked and connected to each other through the first connecting head 91 and the second connecting head 92. The first connecting head 91 and the second connecting head 92 are connected by bolts. After the net sealing release frame 51 and the receiving frame 61 are expanded laterally in parallel, the net sealing area can be increased.

[0054] The winding high-altitude cross-line sealing net mobile operation vehicle has strong maneuverability and can move in complex outdoor environments. It provides stable support for the cross-line sealing net winding and releasing mechanism 50 and the receiving locking net mechanism 60, and can quickly achieve the sealing and protection of the 10kV transmission line being crossed. It is also highly flexible and can flexibly adjust the span width according to the width of different transmission lines, saving time and effort, and can meet the progress requirements of the cross-line construction of energized 10kV transmission lines, making the cross-line construction more convenient and safe.

[0055] The above disclosure is only a preferred embodiment of the present invention, and it is certainly not intended to limit the scope of the present invention. A person skilled in the art can understand that all or part of the processes of the above embodiment and equivalent changes made in accordance with the claims of the present invention are still within the scope of the invention.
