Description

Technical Field

[0001] The present invention belongs to the technical field of power transmission line maintenance, and in particular relates to a power transmission line maintenance device and a use method thereof. Background Art

[0002] When inspecting a transmission line, it is necessary to hang an inspection vehicle on the transmission line, and maintenance personnel sit on the inspection vehicle and move along the transmission line. During the movement, the maintenance personnel inspect the transmission line.

[0003] In order to facilitate the operation of maintenance personnel, the seats of existing maintenance vehicles are generally designed to be movable. For example, a power transmission line maintenance vehicle with publication number CN216625105U has a problem of center of gravity shift, that is, the displacement of the seat causes the force application point of the seat on the maintenance vehicle to change. Therefore, the center of gravity of the maintenance vehicle needs to be compensated during the seat displacement process to ensure that the center of gravity is maintained in a relatively stable position. For example, a power transmission line maintenance vehicle with publication number CN115102093B mainly compensates the center of gravity of the maintenance vehicle through a toolbox, that is, when the seat moves, the toolbox moves relatively, and the center of gravity shift caused by the displacement of the seat is balanced by the toolbox. However, this solution has a defect, that is, there is an obvious weight difference between the seat and the maintenance personnel sitting on the seat and the toolbox. When the distance between the seat and the toolbox is close, the seat has little effect on the center of gravity of the maintenance vehicle, but once the seat and the toolbox move away from each other, the center of gravity will shift to one side of the seat, that is, the farther the distance between the seat and the toolbox, the more serious the center of gravity shift, and thus there is a safety accident. Summary of the invention

[0004] The purpose of the present invention is to provide a power transmission line maintenance device and a method of using the same in order to solve the technical problems in the prior art.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] A power transmission line maintenance device, comprising a base frame and a connecting frame and a pulley mounted thereon, wherein a base plate is mounted on the base frame, a centering assembly is slidably mounted inside the base plate, and a seat assembly and a balancing assembly are slidably mounted on the centering assembly;

[0007] A transmission assembly is installed at the bottom of the base plate, and the transmission assembly includes a motor. The output end of the motor is coaxially connected to a small gear and a large gear, and the small gear is located in the base plate. A shift rack is installed at the bottom of the alignment assembly, and the shift rack is meshed with the small gear. Rack one and rack two are installed on the seat assembly and the balance assembly, respectively, and rack one and rack two are meshed with the large gear.

[0008] As a further optimization or improvement of this solution, the centering assembly includes a displacement plate and a guide rail mounted thereon, the seat assembly and the balancing assembly are slidably connected to the guide rail, a mounting groove is provided on the displacement plate, the pinion and the large gear are connected by a coupling rod, and the large gear and the coupling rod are detachably connected;

[0009] During the installation of the self-aligning assembly, first remove the large gear, then align the mounting groove on the displacement plate and insert the coupling rod. At the same time, the shift rack at the bottom of the displacement plate is inserted into the base plate and meshes with the small gear. Next, install the large gear on the coupling rod, adjust rack one and rack two, so that rack one and rack two mesh with the large gear.

[0010] As a further optimization or improvement of the present solution, the balancing assembly includes a box frame, a tool box is mounted on the box frame, and trash bins are respectively mounted on both sides of the box frame.

[0011] As a further optimization or improvement of the present solution, the seat assembly includes a sliding seat, a compensation rod and a threaded rod are installed at the bottom of the sliding seat, a transmission sleeve is installed at the bottom of the trash bin, the transmission sleeve is provided with gears on the outside and threads on the inside, the threaded rod is connected to the internal threads of the transmission sleeve, the external gear of the transmission sleeve is connected to the bidirectional screw, and transmission plates are installed at both ends of the bidirectional screw respectively, the transmission plate is connected to the pressing plate through a connecting rod, and the pressing plate slides in the side boxes on both sides of the trash bin.

[0012] As a further optimization or improvement of the present solution, pressure plates are rotatably installed on both sides of the opening of the trash bin, and the pressure plates are connected to the side walls of the trash bin through a reset spring. An active rack is installed on the pressing plate, and the active rack is connected to the reversing rack through a reversing gear, and the reversing rack is connected to the pressure plate.

[0013] As a further optimization or improvement of the present solution, shielding plates are installed at the bottom of the seat assembly and the balancing assembly, and balancing rods are installed on both sides of the base plate.

[0014] A method for using a power transmission line maintenance device, the method being applied to the power transmission line maintenance device as described above, the method comprising the following steps:

[0015] Step S1: Connect the pulley to the transmission line, and then the maintenance personnel sit on the slide to perform maintenance work;

[0016] Step S2: When the seat assembly needs to be adjusted toward the power transmission line, the motor is started, and the motor drives the large gear to rotate. Under the action of the large gear meshing with the rack 1 and the rack 2, the rotation of the large gear drives the seat assembly and the balance assembly to move closer to each other;

[0017] Step S3: the slide, the maintenance personnel on the slide, and the balance assembly move toward the bottom of the transmission line, and the weight of the three gradually concentrates toward the bottom of the transmission line;

[0018] Step S4: when the seat assembly needs to be adjusted away from the power transmission line, the motor is started, and the motor drives the large gear and the small gear to rotate synchronously, and the rotation of the large gear drives the seat assembly and the balance assembly to move away from each other;

[0019] Step S5: While the large gear is adjusting the distance between the seat assembly and the balancing assembly, the small gear engages with the shift rack to drive the centering assembly and the seat assembly and balancing assembly thereon to move as a whole toward the balancing assembly, so that the center of gravity of the maintenance vehicle that is offset toward the seat assembly is moved back to directly below the power transmission line.

[0020] As a further optimization or improvement of this solution, step S4 specifically includes the following steps:

[0021] Step S41: When the motor and the large gear drive the slide and the balancing assembly to move relative to each other, the slide drives the threaded rod thereon to move synchronously, the movement of the threaded rod drives the transmission sleeve to rotate, the bidirectional screw rotates synchronously with the transmission sleeve, and the rotation of the bidirectional screw drives the transmission plates at both ends of the bidirectional screw to move closer to each other;

[0022] Step S42: The transmission plate drives the pressing plate to move synchronously through the connecting rod, and the pressing plates move closer to each other and squeeze the garbage inside the garbage bin;

[0023] Step S43: When the pressing plate moves, the reversing rack will be driven to move through the active rack and the reversing gear, so that the reversing rack drives the pressing plate to press the garbage at the mouth of the garbage bin into the garbage bin and seal the mouth of the garbage bin, and then the pressing plate and the pressing plate complete the pressing of the garbage inside the garbage bin.

[0024] Beneficial effects of the present invention:

[0025] (1) When the present invention adjusts the seat assembly in a direction away from the power transmission line, the motor is started, and the motor drives the large gear and the small gear to rotate synchronously. The rotation of the large gear drives the seat assembly and the balance assembly to move away from each other. At this time, due to the weight difference between the slide seat and the maintenance personnel thereon and the balance assembly, the greater the distance between the seat assembly and the balance assembly, the more the center of gravity of the maintenance vehicle as a whole will shift toward the seat assembly. Therefore, while the large gear adjusts the distance between the seat assembly and the balance assembly, the small gear engages with the shift rack to drive the centering assembly and the seat assembly and the balance assembly thereon as a whole to move toward the balance assembly. At this time, the center of gravity of the maintenance vehicle that has shifted toward the seat assembly is moved back to just below the power transmission line, thereby effectively maintaining the stability of the maintenance vehicle, reducing the safety accident of the maintenance vehicle rolling over, and improving the safety of the maintenance vehicle.

[0026] (2) When the motor and the large gear in the present invention drive the slide and the balance assembly to move relative to each other, the slide drives the threaded rod thereon to move synchronously, and the movement of the threaded rod drives the transmission sleeve to rotate. The bidirectional screw rotates synchronously with the transmission sleeve. The rotation of the bidirectional screw drives the transmission plates at both ends of the bidirectional screw to move closer to each other. The transmission plates drive the pressing plates to move synchronously through the connecting rod. The pressing plates move closer to each other and squeeze the garbage inside the trash can. When the pressing plates move, the reversing racks are driven to move through the active racks and the reversing gears, so that the reversing racks drive the pressing plates to press the garbage at the mouth of the trash can into the inside of the trash can and seal the mouth of the trash can, so as to prevent the garbage from jumping out of the trash can when the pressing plates squeeze the garbage inside the trash can. The pressing of the garbage inside the trash can is completed by the pressing plates and the pressing plates, thereby increasing the garbage storage capacity of the trash can and preventing the operating garbage from being blown away from high altitude by the wind, causing environmental pollution.

DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] See also Figure 1-Figure 13 A power transmission line maintenance equipment, comprising a base frame 1 and a connecting frame 2 and a pulley 3 mounted thereon, a base plate 4 is mounted on the base frame 1, a centering assembly 7 is slidably mounted inside the base plate 4, and a seat assembly 8 and a balancing assembly 9 are slidably mounted on the centering assembly 7;

[0044] A transmission assembly 6 is installed at the bottom of the base plate 4, and the transmission assembly 6 includes a motor 601. The output end of the motor 601 is coaxially connected to a small gear 602 and a large gear 604, and the small gear 602 is located in the base plate 4. A shift rack 605 is installed at the bottom of the alignment assembly 7, and the shift rack 605 is meshed with the small gear 602. A rack 1 606 and a rack 2 607 are installed on the seat assembly 8 and the balance assembly 9, respectively, and the rack 1 606 and the rack 2 607 are meshed with the large gear 604.

[0045] Specifically, the centering assembly 7 includes a displacement plate 703 and a guide rail 702 mounted thereon, the seat assembly 8 and the balancing assembly 9 are slidably connected to the guide rail 702, the displacement plate 703 is provided with a mounting groove 701, the pinion 602 and the large gear 604 are connected via a coupling rod 603, and the large gear 604 and the coupling rod 603 are detachably connected;

[0046] During the installation of the centering assembly 7, the large gear 604 is first removed, and then the installation groove 701 on the displacement plate 703 is aligned and inserted into the coupling rod 603. At the same time, the shift rack 605 at the bottom of the displacement plate 703 is inserted into the base plate 4 and meshed with the small gear 602. Then, the large gear 604 is installed on the coupling rod 603, and the rack 1 606 and the rack 2 607 are adjusted so that the rack 1 606 and the rack 2 607 are meshed with the large gear 604.

[0047] It should be noted that the pulley 3 and the connecting frame 2 are detachably connected, that is, a screw and a threaded sleeve. When in use, the pulley 3 and the connecting frame 2 are disassembled, the pulley 3 is connected to the power transmission line, and then the connecting frame 2 and the pulley 3 are connected and fixed.

[0048] When it is necessary to adjust the seat assembly 8 toward the direction of the power transmission line, start the motor 601, which drives the large gear 604 to rotate. Under the action of the large gear 604 meshing with rack 1 606 and rack 2 607, the rotation of the large gear 604 will drive the seat assembly 8 and the balance assembly 9 to move closer to each other. At this time, the slide 803, the maintenance personnel on the slide 803 and the balance assembly 9 move toward the bottom of the power transmission line, and the weight of the three gradually concentrates toward the bottom of the power transmission line, gradually improving the stability of the maintenance car.

[0049] When the seat assembly 8 needs to be adjusted away from the transmission line, the motor 601 is started, and the motor 601 drives the large gear 604 and the small gear 602 to rotate synchronously. Under the action of the large gear 604 meshing with the rack 1 606 and the rack 2 607, the rotation of the large gear 604 will drive the seat assembly 8 and the balance assembly 9 to move away from each other. At this time, due to the weight difference between the slide 803 and the maintenance personnel thereon and the balance assembly 9, the farther the distance between the seat assembly 8 and the balance assembly 9 is, the more the center of gravity of the maintenance vehicle as a whole will shift toward the seat assembly 8. Therefore, see Fig.12 When the large gear 604 adjusts the distance between the seat assembly 8 and the balancing assembly 9, the small gear 602 drives the centering assembly 7 and the seat assembly 8 and the balancing assembly 9 thereon to move toward the balancing assembly 9 as a whole by meshing with the shift rack 605. At this time, the center of gravity of the maintenance vehicle that is offset toward the seat assembly 8 is moved back to just below the power transmission line to maintain the stability of the maintenance vehicle.

[0050] It should be noted that, due to the different transmission ratios between the pinion 602 and the shift rack 605, and between the large gear 604 and rack one 606 and rack two 607, when the large gear 604 drives the relative movement of the distance between the seat assembly 8 and the balance assembly 9, the pinion 602 drives the overall small adjustment of the centering assembly 7 through the shift rack 605. Therefore, the pinion 602 is engaged with the centering assembly 7 and will not interfere with the position adjustment of the seat assembly 8.

[0051] It should be noted that the weight of the inspectors is different, and the weight difference between the slide 803 and the balance assembly 9 is also different. In order to accurately control the center of gravity directly below the transmission line, the small gear 602 and the large gear 604 can be controlled separately by dual motors. The working frequency of the dual motors can be controlled according to the weight of the inspectors to keep the center of gravity directly below the transmission line at all times.

[0052] See also Figure 8 The balancing assembly 9 includes a box frame 901 , a tool box 902 is installed on the box frame 901 , and trash bins 903 are installed on both sides of the box frame 901 .

[0053] It should be noted that the present invention is provided with a tool box 902 and a trash bin 903, so that maintenance personnel can conveniently put operation waste into the trash bin 903, thereby avoiding accidental injury to personnel by dropping waste from a high altitude.

[0054] See also Figure 7-Figure 11 The seat assembly 8 includes a slide 803, a positioning rod 801 and a threaded rod 802 are installed at the bottom of the slide 803, a transmission sleeve 905 is installed at the bottom of the trash can 903, the transmission sleeve 905 is gear-set on the outside and threaded on the inside, the threaded rod 802 is threadedly connected to the internal thread of the transmission sleeve 905, the external gear of the transmission sleeve 905 is transmission-connected to the bidirectional screw 906, and transmission plates 907 are respectively installed at both ends of the bidirectional screw 906, and the transmission plate 907 is connected to the pressing plate 909 through a connecting rod 908, and the pressing plate 909 is located in the side box 904 on both sides of the trash can 903 and slides.

[0055] Specifically, pressure plates 913 are rotatably installed on both sides of the opening of the trash bin 903, and the pressure plates 913 are connected to the side walls of the trash bin 903 through reset springs 914. An active rack 910 is installed on the pressing plate 909, and the active rack 910 is connected to the reversing rack 912 through a reversing gear 911, and the reversing rack 912 is connected to the pressure plate 913.

[0056] It should be noted that the two ends of the bidirectional screw 906 are reciprocating screws with opposite thread directions. Therefore, the rotation of the bidirectional screw 906 will drive the transmission plates 907 at both ends of the bidirectional screw 906 to move relative to each other. Since the two ends of the bidirectional screw 906 are reciprocating screws, when the transmission assembly 6 drives the seat assembly 8 to move and adjust in one direction, the garbage can be compressed and reset.

[0057] When the pressing plates 909 move toward each other, see Fig.10 The active rack 910 on the pressing plate 909 will drive the reversing rack 912 to move in the opposite direction through the reversing gear 911, so that the reversing rack 912 drives the pressing plate 913 to rotate and press the garbage at the mouth of the garbage bin 903, squeezing the garbage at the mouth of the garbage bin 903 into the inside of the garbage bin 903.

[0058] It should be noted that when maintenance personnel repair cables, the operational waste generated includes the cable shielding layer and filling rope, etc. These wastes occupy a large space in the waste bin 903 and are light in weight, which makes the waste bin 903 easy to fill up and the waste at the mouth of the waste bin 903 easy to be blown away by high winds. Therefore, in order to increase the amount of waste collected in the waste bin 903 and avoid operational waste being blown away from high altitudes by the wind and causing environmental pollution.

[0059] In the present invention, when the motor 601 and the large gear 604 drive the slide 803 and the balance assembly 9 to move relative to each other, the slide 803 drives the threaded rod 802 thereon to move synchronously. Fig. 9 The threaded rod 802 moves to drive the transmission sleeve 905 to rotate, and the bidirectional screw 906 rotates synchronously with the transmission sleeve 905. The rotation of the bidirectional screw 906 drives the transmission plates 907 at both ends of the bidirectional screw 906 to move closer to each other. The transmission plate 907 drives the pressing plate 909 to move synchronously through the connecting rod 908. When the pressing plates 909 move closer to each other, they will squeeze the garbage inside the garbage bin 903. When the pressing plates 909 move, they will drive the active rack 910 and the reversing gear 911 The reversing rack 912 moves, so that the reversing rack 912 drives the pressure plate 913 to press the garbage at the mouth of the garbage bin 903 into the garbage bin 903 and seal the mouth of the garbage bin 903, to prevent the garbage from jumping out of the garbage bin 903 when the pressure plate 909 squeezes the garbage inside the garbage bin 903. The pressure plate 909 and the pressure plate 913 are used to suppress the garbage inside the garbage bin 903, thereby increasing the garbage storage capacity of the garbage bin 903 and preventing the operating garbage from being blown away from high altitude by the wind to cause environmental pollution.

[0060] See also Figure 1 A shielding plate 10 is installed at the bottom of the seat component 8 and the balancing component 9, and a balancing rod 5 is installed on both sides of the base plate 4.

[0061] It should be noted that the base plate 4 is laterally connected to the base frame 1 through the balance rod 5 to further improve the stability of the maintenance vehicle. The shielding plate 10 at the bottom of the seat assembly 8 and the balance assembly 9 is used to shield and protect the transmission assembly 6 to prevent leakage between the transmission assemblies 6.

[0062] See also Figure 1-Figure 6As shown, the present invention is a method for using a power transmission line maintenance device, the method is applied to the power transmission line maintenance device as described in the above embodiment, and the method comprises the following steps:

[0063] Step S1: connect the pulley 3 to the power transmission line, and then the maintenance personnel sit on the slide 803 to perform maintenance work;

[0064] Step S2: When the seat assembly 8 needs to be adjusted toward the power transmission line, the motor 601 is started, and the motor 601 drives the large gear 604 to rotate. Under the action of the large gear 604 meshing with the rack 1 606 and the rack 2 607, the large gear 604 rotates to drive the seat assembly 8 and the balance assembly 9 to move closer to each other;

[0065] Step S3: the slide 803, the maintenance personnel on the slide 803 and the balance assembly 9 move toward the bottom of the transmission line, and the weight of the three gradually concentrates toward the bottom of the transmission line;

[0066] Step S4: When the seat assembly 8 needs to be adjusted away from the power transmission line, the motor 601 is started, and the motor 601 drives the large gear 604 and the small gear 602 to rotate synchronously, and the rotation of the large gear 604 drives the seat assembly 8 and the balance assembly 9 to move away from each other;

[0067] Step S5: While the large gear 604 adjusts the distance between the seat assembly 8 and the balancing assembly 9, the small gear 602 drives the centering assembly 7 and the seat assembly 8 and the balancing assembly 9 thereon to move as a whole toward the balancing assembly 9 by meshing with the shift rack 605, so that the center of gravity of the maintenance vehicle that is offset toward the seat assembly 8 is moved back to directly below the power transmission line.

[0068] like Figure 7-10 As shown, as a preferred embodiment of the present invention, step S4 specifically includes the following steps:

[0069] Step S41: When the motor 601 and the large gear 604 drive the slide 803 and the balancing assembly 9 to move relative to each other, the slide 803 drives the threaded rod 802 thereon to move synchronously, and the movement of the threaded rod 802 drives the transmission sleeve 905 to rotate, and the bidirectional screw 906 rotates synchronously with the transmission sleeve 905, and the rotation of the bidirectional screw 906 drives the transmission plates 907 at both ends of the bidirectional screw 906 to move closer to each other;

[0070] Step S42: The transmission plate 907 drives the pressing plate 909 to move synchronously through the connecting rod 908, and the pressing plates 909 move closer to each other and squeeze the garbage inside the garbage bin 903;

[0071] Step S43: When the pressing plate 909 moves, it will drive the reversing rack 912 to move through the active rack 910 and the reversing gear 911, so that the reversing rack 912 drives the pressing plate 913 to press the garbage at the mouth of the garbage bin 903 into the garbage bin 903 and seal the mouth of the garbage bin 903, and then the pressing plate 909 and the pressing plate 913 complete the pressing of the garbage inside the garbage bin 903.

[0072] The implementation principle of the present invention is: when in use, the pulley 3 and the connecting frame 2 are disassembled, the pulley 3 is connected to the power transmission line, and then the connecting frame 2 and the pulley 3 are connected and fixed, and then the maintenance personnel sit on the slide 803 to perform maintenance work.

[0073] When the seat assembly 8 needs to be adjusted toward the direction of the power transmission line, the motor 601 is started, and the motor 601 drives the large gear 604 to rotate. Under the action of the large gear 604 meshing with the rack 1 606 and the rack 2 607, the large gear 604 rotates to drive the seat assembly 8 and the balance assembly 9 to move closer to each other. At this time, the slide 803, the maintenance personnel on the slide 803 and the balance assembly 9 move toward the bottom of the power transmission line, and the weight of the three gradually concentrates toward the bottom of the power transmission line, gradually improving the stability of the maintenance vehicle;

[0074] When the seat assembly 8 needs to be adjusted away from the power transmission line, the motor 601 is started, and the motor 601 drives the large gear 604 and the small gear 602 to rotate synchronously. The rotation of the large gear 604 drives the seat assembly 8 and the balance assembly 9 to move away from each other. At this time, due to the weight difference between the slide 803 and the maintenance personnel thereon and the balance assembly 9, the greater the distance between the seat assembly 8 and the balance assembly 9, the more the center of gravity of the maintenance vehicle as a whole will shift toward the seat assembly 8. Therefore, see Figure 12-13 While the large gear 604 adjusts the distance between the seat assembly 8 and the balancing assembly 9, the small gear 602 drives the centering assembly 7 and the seat assembly 8 and the balancing assembly 9 thereon to move toward the balancing assembly 9 as a whole by meshing with the shift rack 605. At this time, the center of gravity of the maintenance vehicle that is offset toward the seat assembly 8 is moved back to just below the power transmission line, thereby effectively maintaining the stability of the maintenance vehicle.

[0075] When the motor 601 and the large gear 604 drive the slide 803 and the balancing assembly 9 to move relative to each other, the slide 803 drives the threaded rod 802 thereon to move synchronously. Fig. 9, the threaded rod 802 moves to drive the transmission sleeve 905 to rotate, and the bidirectional screw 906 rotates synchronously with the transmission sleeve 905. The rotation of the bidirectional screw 906 drives the transmission plates 907 at both ends of the bidirectional screw 906 to move closer to each other, and the transmission plate 907 drives the pressing plate 909 to move synchronously through the connecting rod 908. The pressing plates 909 move closer to each other and squeeze the garbage inside the garbage bin 903. When the pressing plate 909 moves, it will drive the reversing rack 912 to move through the active rack 910 and the reversing gear 911, so that the reversing rack 912 drives the pressing plate 913 to press the garbage at the mouth of the garbage bin 903 into the garbage bin 903 and block the mouth of the garbage bin 903, so as to prevent the garbage from jumping out of the garbage bin 903 when the pressing plate 909 squeezes the garbage inside the garbage bin 903. The pressing plate 909 and the pressing plate 913 complete the pressing of the garbage inside the garbage bin 903, thereby increasing the garbage storage capacity of the garbage bin 903 and preventing the operating garbage from being blown away from high altitude by the wind to cause environmental pollution.
