Description

Technical Field

[0001] The present invention belongs to the technical field of transmission line maintenance equipment, and specifically relates to an intelligent electric flying vehicle for transmission line maintenance. Background Art

[0002] The maintenance of transmission lines is an important link to ensure the safe and stable operation of the power system; its main purpose is to regularly inspect and maintain transmission lines and related equipment, and timely discover and eliminate potential faults; the maintenance methods are generally divided into live maintenance and power-off maintenance, and the specific selection depends on the importance of the line and the maintenance content. Through regular maintenance, the service life of transmission lines can be effectively extended, the failure rate can be reduced, and the reliability and safety of power supply can be guaranteed.

[0003] During the maintenance of transmission lines, a maintenance flying vehicle is usually used. Since there are obstacles such as shock dampers and spacer dampers on overhead transmission lines, traditional maintenance flying vehicles cannot smoothly cross these obstacles. It is easy for the walking wheels to deviate from the cable when crossing the obstacles, making the flying vehicle itself unbalanced. At the same time, traditional maintenance flying vehicles will slide when moving, which fails to guarantee the personal safety of maintenance personnel and is not conducive to the maintenance of transmission lines. Therefore, in view of the above problems, it is necessary to design an intelligent electric flying vehicle for transmission line maintenance to solve the above problems. Summary of the Invention

[0004] To achieve the above object, the present invention provides the following technical solution: An intelligent electric flying vehicle for transmission line maintenance, including a vehicle frame, the vehicle frame is a rectangular hanging basket structure for the convenience of workers to ride. On both sides of the top of the vehicle frame, hoisting side plates are installed. On both sides of the upper parts of the two hoisting side plates, obstacle turning shafts are rotatably connected. At the ends of the four obstacle turning shafts on the opposite sides of the two hoisting side plates, triangular turning plates are fixedly installed. On the triangles on the sides of the four triangular turning plates away from the hoisting side plates, moving pulleys are installed. On the sides of the four triangular turning plates close to the hoisting side plates, stepper motors A for driving the moving pulleys are installed. On the lower parts of the opposite sides of the two hoisting side plates, two moving anti-slip auxiliary clamping components are installed, and on the lower parts of the opposite sides of the two hoisting side plates, forward and reverse motors for positive and negative adjustment of the moving anti-slip auxiliary clamping components are installed.

[0005] Preferably, at the ends of the obstacle turning shafts away from the triangular turning plates, reverse transmission sub-sprockets are fixedly installed. At the bottom of the vehicle frame, a double-output shaft stepper motor is installed. On both output ends of the double-output shaft stepper motor, reverse transmission main sprockets are fixedly installed. Between adjacent two reverse transmission sub-sprockets and reverse transmission main sprockets, reverse transmission chains are installed, so that the moving pulleys can cross obstacles such as shock dampers and spacer dampers on the wire.

[0006] Preferably, a moving transmission shaft is rotatably connected to each of the three corners of the triangular turning plate. A moving pulley is fixedly installed in the middle of the moving transmission shaft. A moving transmission driven sprocket is fixedly installed at one end of the moving transmission shaft. The output end of the stepper motor A extends to one side of the triangular turning plate and is fixedly installed with a moving transmission driving sprocket. A moving transmission chain is installed between the three moving transmission driven sprockets and the moving transmission driving sprocket on the triangular turning plate, so as to drive the moving pulley to rotate and move on the wire.

[0007] Preferably, a clamping anti-slip rubber ring A is fixedly installed in the middle of each of the moving pulleys. The contact between the clamping anti-slip rubber ring A and the wire can increase the friction and play an anti-slip role. Active transmission bevel gears are fixedly installed at the ends of the moving transmission shafts far from the moving transmission driven sprockets.

[0008] Preferably, each of the moving anti-slip auxiliary clamping components includes a pair of sliding rods fixedly installed on the hoisting side plate. A moving slider is slidably installed between each pair of sliding rods. Installation blocks are fixedly installed on the tops of the moving sliders. A threaded groove is formed between the middle of the moving slider and the bottom of the installation block. The output end of the forward and reverse motor is fixedly connected with a threaded shaft threadedly connected to the threaded groove, so as to effectively adjust the up and down movement of the installation block.

[0009] Preferably, a synchronous transmission shaft is rotatably installed in the middle of one side of each of the installation blocks. A contact clamping wheel matching the moving pulley is fixedly installed at one end of the synchronous transmission shaft. The upward movement of the contact clamping wheel can be inserted into the inside of the moving pulley, and a clamping anti-slip rubber ring B is installed on the surface of the contact clamping wheel. A bevel gear A is fixedly installed in the middle of the synchronous transmission shaft, so that the upward movement of the contact clamping wheel cooperates with the moving pulley to clamp the wire and prevent the moving pulley from sliding.

[0010] Preferably, a hollow sleeve block is fixedly installed on the upper part of one side of each of the installation blocks. A connecting sleeve is rotatably installed in the middle of the hollow sleeve block. A connecting column is fixedly installed inside the connecting sleeve. Bevel gears B meshing with the bevel gear A are fixedly installed at the bottoms of the connecting columns, so as to effectively perform transmission.

[0011] Preferably, a cross-shaped square slot is formed at the top of each of the connecting columns. A square plug shaft is movably inserted into the cross-shaped square slot. The top of the square plug shaft is fixedly connected with a driven transmission bevel gear. The driven transmission bevel gear matches the active transmission bevel gear and can be meshed. A square block is slidably installed in the middle of the cross-shaped square slot. The bottom of the square plug shaft is fixedly connected with the top of the square block. A return spring is fixedly connected between the bottom of the square block and the bottom of the cross-shaped square slot. When the clamping anti-slip rubber ring B moves upward to be in close contact with the wire, the driven transmission bevel gear and the active transmission bevel gear can be effectively meshed.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] (1) During operation, the intelligent electric flying car has an active obstacle crossing function and an anti-skid function by providing a frame, a lifting side plate, an obstacle flip shaft, a triangular flip plate, a moving pulley, a stepper motor A, a moving anti-skid auxiliary clamping component and a forward and reverse motor. The active obstacle crossing function can cross obstacles such as shock-absorbing hammers and spacers on the transmission line to enable the flying car to move effectively. The anti-skid function can prevent the flying car from sliding while moving and ensure that the flying car can move stably, thereby ensuring that the flying car can move safely and stably on the transmission line, effectively ensuring the personal safety of the maintenance personnel, and being conducive to the maintenance of the transmission line. At the same time, the intelligent electric flying car has a simple structural design, is easy to use, and is stable and reliable to adjust. Its performance can meet the use requirements of transmission line maintenance;

[0014] (2) By starting the double-output shaft stepper motor, the double-output shaft stepper motor drives the main sprockets of the flip transmission at both ends to rotate. The rotation of the main sprocket of the flip transmission will drive the obstacle flip shaft to rotate through the flip transmission chain and the flip transmission secondary sprocket. The rotation of the obstacle flip shaft will drive the three moving pulleys on it to flip 120 degrees. The flipping of the moving pulley can climb over obstacles such as shock-absorbing hammers and spacer bars on the wires;

[0015] (3) By starting the stepper motor A, the stepper motor A drives the mobile transmission main sprocket to rotate. The rotation of the mobile transmission main sprocket drives the three mobile transmission sub-sprockets to rotate through the mobile transmission chain. The rotation of the mobile transmission sub-sprocket drives the mobile transmission shaft and the mobile pulley to rotate, thereby causing the two mobile pulleys located on the wire to roll and move. Finally, the frame is driven to move on the overhead transmission line through four triangular flip plates and two lifting side plates, so that workers can perform maintenance operations on the transmission line.

[0016] (4) The threaded shaft is driven to rotate by starting the forward and reverse motors. The rotation of the threaded shaft causes the movable slider and the mounting block to move upward and adjust through the threaded groove. At the same time, the movable slider and the mounting block can be stably moved and adjusted through the slide rod. When the mounting block moves upward, the synchronous transmission shaft and the conflict clamping wheel are driven to move upward, so that the conflict clamping wheel drives the clamping anti-skid rubber ring B to be clamped into the inside of the conflict clamping wheel, so that the clamping anti-skid rubber ring B cooperates with the clamping anti-skid rubber ring A so that the conflict clamping wheel and the movable pulley can stably and firmly clamp and fix the wires.

[0017] When the mounting block moves upward, it will drive the connecting column, the square plug shaft and the passive transmission bevel gear to move upward. The upward movement of the passive transmission bevel gear will mesh with the active transmission bevel gear. As the upward movement continues, the clamping anti-skid rubber ring B cooperates with the clamping anti-skid rubber ring A, so that the contact clamping wheel and the moving pulley can stably and firmly clamp and fix the wire. The continued upward movement will drive the connecting column, the square plug shaft and the passive transmission bevel gear to continue to move upward. Since the passive transmission bevel gear meshes with the active transmission bevel gear, the passive transmission bevel gear and the square plug shaft cannot continue to move upward. At this time, the upward movement of the connecting column will compress the reset spring through the square block, thereby ensuring the continuity of the upward movement.

[0018] When the clamping anti-skid rubber ring B cooperates with the clamping anti-skid rubber ring A, the conflict clamping wheel and the moving pulley can stably and firmly clamp and fix the electric wire, so that the flying car will not slide; and when the moving pulley rotates, the active transmission bevel gear will be driven to rotate through the moving transmission shaft, and the rotation of the active transmission bevel gear will transmit the transmission to the passive transmission bevel gear to rotate the square plug shaft, and the rotation of the square plug shaft will drive the connecting column to rotate through the square block, and the rotation of the connecting column will drive the bevel gear B to rotate, and the rotation of the bevel gear B will transmit the transmission to the bevel gear A and drive the conflict clamping wheel to rotate, so that the conflict clamping wheel and the moving pulley can rotate synchronously relative to each other and move stably on the electric wire.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

Both sides of the top of the vehicle frame 1 are installed with lifting side panels 2, and both sides of the upper parts of the two lifting side panels 2 are rotatably connected with obstacle turning shafts 3. The four obstacle turning shafts 3 are located at the ends of the opposite sides of the two lifting side panels 2 and are fixedly installed with triangular turning plates 4. The four triangular turning plates 4 are installed with moving pulleys 5 on the triangles away from the lifting side panels 2, and the four triangular turning plates 4 are installed on the side close to the lifting side panels 2. Stepping motors for driving the moving pulleys 5 are installed. Machine A6, two movable anti-skid auxiliary clamping parts 7 are installed at the lower parts of the opposite sides of the two lifting side plates 2, and two forward and reverse motors 8 for adjusting the movable anti-skid auxiliary clamping parts 7 are installed at the lower parts of the opposite sides of the two lifting side plates 2. During installation, the two lifting side plates 2 are moved up from the outside of the wires on both sides of the overhead transmission line, and finally the four movable pulleys 5 on the lifting side plates 2 are clamped above the same wire, and the eight movable pulleys 5 are rolled on the wires on both sides of the overhead transmission line to drive the device to move.

[0033] A flip transmission sub-sprocket 9 is fixedly installed at one end of the obstacle flip shaft 3 away from the triangular flip plate 4, a double-output shaft stepper motor 10 is installed at the bottom of the frame 1, and a flip transmission main sprocket 11 is fixedly installed at both output ends of the double-output shaft stepper motor 10, and a flip transmission chain 12 is installed between two adjacent flip transmission sub-sprockets 9 and the flip transmission main sprocket 11, so that the movable pulley 5 can climb over obstacles such as shock-absorbing hammers and spacer bars on the electric wires.

[0034] By starting the double-output shaft stepper motor 10, the double-output shaft stepper motor 10 drives the flip transmission main sprocket 11 at both ends to rotate, and the rotation of the flip transmission main sprocket 11 will drive the obstacle flip shaft 3 to rotate through the flip transmission chain 12 and the flip transmission sub-sprocket 9. The rotation of the obstacle flip shaft 3 will drive the three movable pulleys 5 thereon to flip one hundred and twenty degrees. The flipping of the movable pulley 5 can climb over obstacles such as shock-absorbing hammers and spacer bars on the electric wire.

[0035] The intelligent electric flying car has an active obstacle crossing function and an anti-skid function. The active obstacle crossing function can cross obstacles such as shock-absorbing hammers and spacers on the transmission line to enable the flying car to move effectively. The anti-skid function can prevent the flying car from sliding while moving and ensure the stable movement of the flying car, thereby ensuring that the flying car can move safely and stably on the transmission line, effectively protecting the personal safety of maintenance personnel and being beneficial to the maintenance of transmission lines.

[0036] At the same time, the intelligent electric flying car has a simple structural design, is easy to use, and is stable and reliable to adjust. Its performance can meet the use requirements of transmission line maintenance.

[0037] Embodiment 2. On the basis of Embodiment 1, moving drive shafts 13 are rotatably connected to the three corners of the triangular turning plate 4. The moving pulleys 5 are fixedly installed in the middle of the moving drive shafts 13. One end of the moving drive shaft 13 is fixedly installed with a moving driven sprocket 14. The output end of the stepping motor A6 extends to one side of the triangular turning plate 4 and is fixedly installed with a moving driving sprocket 15. A moving drive chain 16 is installed between the three moving driven sprockets 14 and the moving driving sprocket 15 on the triangular turning plate 4, so as to drive the moving pulley 5 to rotate and move on the electric wire; Clamping anti-slip rubber rings A17 are fixedly installed in the middle of the moving pulleys 5. The contact between the clamping anti-slip rubber rings A17 and the electric wire can increase the friction and play an anti-slip role. One end of the moving drive shaft 13 away from the moving driven sprocket 14 is fixedly installed with a driving bevel gear 18.

[0038] By starting the stepping motor A6, the stepping motor A6 drives the moving driving sprocket 15 to rotate. The rotation of the moving driving sprocket 15 drives the three moving driven sprockets 14 to rotate through the moving drive chain 16. The rotation of the moving driven sprocket 14 drives the moving drive shaft 13 and the moving pulley 5 to rotate, so that the two moving pulleys 5 located on the electric wire roll and move. Finally, through the four triangular turning plates 4 and the two lifting side plates 2, the vehicle frame 1 is driven to move on the overhead transmission line, so that workers can perform maintenance operations on the transmission line.

[0039] Embodiment 3. On the basis of Embodiment 1, each of the moving anti-slip auxiliary clamping components 7 includes a pair of sliding rods 19 fixedly installed on the lifting side plate 2. A moving slider 20 is slidably installed between each pair of sliding rods 19. Installation blocks 21 are fixedly installed on the tops of the moving sliders 20. A threaded groove 22 is formed between the middle of the moving slider 20 and the bottom of the installation block 21. The output end of the forward and reverse motor 8 is fixedly connected with a threaded shaft 23 threadedly connected to the threaded groove 22, so as to effectively adjust the up and down movement of the installation block 21;

[0040] By starting the forward and reverse motor 8 to drive the threaded shaft 23 to rotate, the rotation of the threaded shaft 23 will move the moving slider 20 and the installation block 21 upward through the threaded groove 22. At the same time, the moving slider 20 and the installation block 21 can be stably moved and adjusted through the sliding rod 19.

[0041] A synchronous transmission shaft 24 is rotatably mounted in the middle of one side of the mounting block 21, and a contact clamping wheel 25 matching the moving pulley 5 is fixedly mounted on one end of the synchronous transmission shaft 24. The upward movement of the contact clamping wheel 25 can be clamped into the inside of the moving pulley 5, and a clamping anti-skid rubber ring B26 is installed on the surface of the contact clamping wheel 25. A bevel gear A27 is fixedly mounted in the middle of the synchronous transmission shaft 24, so that the contact clamping wheel 25 moves upward to cooperate with the moving pulley 5 to clamp the wire and prevent the moving pulley 5 from sliding;

[0042] When the mounting block 21 moves upward, it will drive the synchronous transmission shaft 24 and the contact clamping wheel 25 to move upward, so that the contact clamping wheel 25 drives the clamping anti-skid rubber ring B26 to be clamped into the inside of the contact clamping wheel 25, so that the clamping anti-skid rubber ring B26 cooperates with the clamping anti-skid rubber ring A17 so that the contact clamping wheel 25 and the movable pulley 5 can stably and firmly clamp and fix the wires.

[0043] A hollow sleeve block 28 is fixedly installed on the upper part of one side of the mounting block 21, and a connecting ring 29 is rotatably installed in the middle part of the hollow sleeve block 28. A connecting column 30 is fixedly installed inside the connecting ring 29, and a bevel gear B31 meshing with the bevel gear A27 is fixedly installed at the bottom of the connecting column 30, so that transmission can be effectively performed; a cross-square slot is provided on the top of the connecting column 30, and a square plug shaft 32 is movably inserted inside the cross-square slot, and a passive transmission bevel gear 33 is fixedly connected to the top of the square plug shaft 32, and the passive transmission bevel gear 33 matches and can be meshed with the active transmission bevel gear 18; a square block 34 is slidably installed in the middle part of the cross-square slot, and the bottom of the square plug shaft 32 is fixedly connected to the top of the square block 34, and a reset spring 35 is fixedly connected between the bottom of the square block 34 and the bottom of the cross-square slot, so that when the clamping anti-slip rubber ring B26 moves up and is in close contact with the wire, the passive transmission bevel gear 33 and the active transmission bevel gear 18 can be effectively meshed and connected;

[0044] When the mounting block 21 moves upward, it will drive the connecting column 30, the square plug shaft 32 and the passive transmission bevel gear 33 to move upward, and the upward movement of the passive transmission bevel gear 33 will be meshed and connected with the active transmission bevel gear 18, and as the upward movement continues, the clamping non-slip rubber ring B26 cooperates with the clamping non-slip rubber ring A17 so that the contact clamping wheel 25 and the moving pulley 5 can stably and firmly clamp and fix the wires, and the continued upward movement will drive the connecting column 30, the square plug shaft 32 and the passive transmission bevel gear 33 to continue to move upward. Since the passive transmission bevel gear 33 is meshed with the active transmission bevel gear 18, the passive transmission bevel gear 33 and the square plug shaft 32 cannot continue to move upward. At this time, the upward movement of the connecting column 30 will compress the reset spring 35 through the square block 34, thereby ensuring the continuity of the upward movement;

[0045] When the clamping anti-slip rubber ring B26 and the clamping anti-slip rubber ring A17 cooperate to firmly clamp and fix the wire by the abutting clamping wheel 25 and the moving pulley 5, the flying vehicle will not slide.

[0046] When the moving pulley 5 rotates, the driving transmission bevel gear 18 will be driven to rotate through the moving transmission shaft 13. The rotation of the driving transmission bevel gear 18 will drive the driven transmission bevel gear 33 to rotate, causing the square plug shaft 32 to rotate. The rotation of the square plug shaft 32 will drive the connecting column 30 to rotate through the square block 34. The rotation of the connecting column 30 will drive the bevel gear B31 to rotate. The rotation of the bevel gear B31 will drive the bevel gear A27 to rotate, driving the abutting clamping wheel 25 to rotate. Thus, the abutting clamping wheel 25 and the moving pulley 5 rotate synchronously relative to each other and move stably on the wire.
