Description

Technical Field

[0002] With the rapid development of power grids, the power grid structure is becoming more and more perfect, and numerous transmission lines and towers can be seen everywhere. Power workers often find various types of defects and hidden dangers during daily inspections and maintenance. If the suspension clamp bolts used by the straight tower to bear the conductor load are loose, the conductor is very likely to fall off. In addition, due to the compact arrangement of the conductors on the towers, the double-circuit and multi-circuit conductors have a margin for equipotential live operations that often cannot meet the work requirements. If the power is cut off and the bolts are tightened, it will cause power supply loss. How to safely tighten the loose bolts without power outages is a difficulty and pain point we are currently facing.

[0037] When in use, the insulating tube 4 is installed into the shaft sleeve 5 on the T-block 12, and then the spacing between the mounting frame 14 and the main box 6 is adjusted by the spacing adjustment component, and then the spacing between the two sets of tightening plates is adjusted by the adaptation adjustment component, so that the two sets of tightening plates can tighten the suspension wire clamp bolts of different sizes, avoiding the need to repeatedly replace the bolt sleeve for positioning the suspension wire clamp bolts, and then the disassembly sleeve 17 is closed on the outside of the power grid bolt. At this time, the two sets of tightening plates will be closed on the outside of the power grid bolt, and then the personnel hold the rubber hand-held sleeve 2 on the insulating hand-held rod 1, and then start the motor 7, and the motor 7 cooperates with the speed controller 20 to drive the sleeve The tube 13 rotates, and when the sleeve 13 rotates, it will drive the outer hexagonal rod 21 to rotate. When the outer hexagonal rod 21 rotates, it will drive the connecting shaft 22 to rotate.

A return spring 40 is sleeved on the outer surface of the sliding column 34, and one end of the return spring 40 is fixedly connected to the straight plate 33, and the other end of the return spring 40 is fixedly connected to the inner wall of the disassembly sleeve 17.

[0039] When it is necessary to adapt to the tightening of bolts of different sizes, the operator can rotate the internal threaded sleeve 43, and the internal threaded sleeve 43 is threadedly connected to the external threaded tube 42. When the internal threaded sleeve 43 is twisted, the external threaded tube 42 will move forward and backward along the axial direction of the disassembly sleeve 17, and the external threaded tube 42 will drive the tapered sleeve 37 to move forward and backward. When the tapered sleeve 37 moves forward and backward, it will drive the two groups of inclined plates 36 to move relative to each other. When the two groups of inclined plates 36 move relative to each other, they will drive their corresponding straight plates 33 to move closer to the direction of the power grid bolts. At this time, the two groups of straight plates 33 will be tightly pressed against the outer surface of the power grid bolts. When the tapered sleeve 37 moves backward, the two groups of straight plates 33 will move away from each other under the action of the reset spring 40, and then the adaptable adjustment component can be used to adapt to the positioning of power grid bolts of different sizes, avoiding the need to match bolt sleeves of different sizes to position the current bolt.

[0040] See also Figure 6 and Fig. 9 As shown, the inclined surface of the inclined plate 36 is matched with the inclined surface of the inner wall of the tapered sleeve 37, and the outer surface of the externally threaded tube 42 is provided with a plurality of limit slides 45, and the outer surface of the limit slides 45 is slidably connected to the limit slider 47, and the outer surface of the externally threaded tube 42 is sleeved with a limit ring 44, and the limit slider 47 is fixedly connected to the inner wall of the limit ring 44, and the limit ring 44 is fixedly connected to the mounting plate 38 through a connecting frame 48 by screws.

[0041] When the internal thread sleeve 43 is screwed to drive the external thread tube 42 to move forward and backward, the limiting slider 47 will slide along the direction of the limiting sliding opening 45 , thereby guiding and limiting the external thread tube 42 .

[0042] See also Figure 6 As shown, the inner sides of the two groups of straight plates 33 are provided with a plurality of anti-skid grooves, and the anti-skid grooves can improve the positioning effect of the straight plates 33 on the power grid bolts and avoid slipping when the straight plates 33 are positioning the bolts.

[0044] When it is necessary to adjust the spacing of the mounting bracket 14, the personnel can rotate the internal thread adjustment sleeve 19. Since the internal thread adjustment sleeve 19 is threadedly connected to the adjusting screw 18, the mounting bracket 14 will move horizontally when the internal thread sleeve 19 rotates. At this time, the connecting shaft 22 will pull the external hexagonal rod 21 to slide along the outer surface of the sleeve 13, thereby not only not affecting the adjustment function of the spacing adjustment component, but also limiting the mounting bracket 14 at the same time.

[0045] See also Figure 1-5 As shown, the driving assembly includes an active bevel gear 31 and a driven bevel gear 32, wherein the active bevel gear 31 is fixedly mounted on the connecting shaft 22, and the driven bevel gear 32 is fixedly sleeved on the outer surface of the disassembly sleeve 17, and the active bevel gear 31 is meshed with the driven bevel gear 32. Through the meshing of the active bevel gear 31 and the driven bevel gear 32, the disassembly sleeve 17 can be driven to rotate when the motor 7 is started.

[0047] When adjusting the length of the device up and down, pull the length of the insulating handle rod 1, and then the operator can rotate the rotating sleeve 9. When the rotating sleeve 9 rotates, it will drive the inner conical tightening sleeve 10 to rotate. The inner threaded tightening sleeve 10 is threadedly connected with the threaded part on the inclined surface block 11. The inner conical tightening sleeve 10 will tighten a number of inclined surface blocks, and the inclined surface blocks will be tightly pressed against the insulating tube 4, thereby positioning the length of the device.

[0049] The reflector 15 provided in the device can adjust the angle, which is convenient for the operator to observe the specific position of the power grid bolts and is more convenient for the operator to put on the power grid bolts, thereby optimizing the operation process and saving work costs and time. When the angle of the reflector 15 is adjusted, tighten the hexagonal nut 28, and the tightening sleeve 29 will be tightened on the corresponding connecting block 16, thereby positioning the angle of the reflector 15.

[0050] See also Figure 5-9As shown, the rotary joint 46 is fixedly connected with a rust removal nozzle 24, the end of the insulating hand-held rod 1 is fixedly connected with a rust remover inlet pipe 3, the main box 6 is fixedly installed with a heating box 25, the inner wall of the heating box 25 is fixedly connected with a heat insulation layer, the interior of the heat insulation layer is fixedly installed with a heat conductive silicone layer, the interior of the heat conductive silicone layer is fixedly installed with a coil 26, one end of the coil 26 is fixedly extended into the interior of the insulating tube 4, the coil 26 is fixedly connected with the external threaded tube 42 through a soft infusion tube 8, and a plurality of electric heating tubes are fixedly penetrated through the heat conductive silicone layer inside the main box 6.

[0051] The present invention can not only conveniently tighten the loose bolts on the power grid, but also disassemble the power grid bolts that need to be disassembled. In order to prevent the power grid bolts from rusting and causing difficulty in disassembly, the external rust removal liquid can enter the insulating hand-held rod 1 through the rust removal agent inlet pipe 3 in sequence, and then enter the insulating tube 4, and then enter the coil 26. The rust removal liquid then enters the external threaded tube 42 through the soft infusion tube 8, and then enters the rotary joint 46. Finally, the rust removal liquid is sprayed out through the rust removal nozzle 24. In addition, in order to improve the rust removal effect of the rust removal liquid, the electric heating tube in the heating box 25 can be started, and the heat generated by the electric heating tube will be transferred to the thermal conductive silicone layer, and the thermal conductive silicone layer will transfer the heat to the rust removal liquid in the coil 26. The heated rust removal liquid will transfer the heat to the bolts on the power grid. Through the principle of thermal expansion and contraction, the bolts on the power grid will generate expansion gaps, which makes it convenient for personnel to unscrew the bolts. The present invention can not only tighten the bolts, but also unscrew the bolts, which is convenient for disassembling and assembling bolts that are difficult to disassemble.

[0052] Working principle: When in use, the insulating tube 4 is installed into the shaft sleeve 5 on the T-block 12, and then the spacing between the mounting frame 14 and the main box 6 is adjusted by the spacing adjustment component. When the spacing of the mounting frame 14 needs to be adjusted, the personnel can rotate the internal thread adjustment sleeve 19. Since the internal thread adjustment sleeve 19 is threadedly connected with the adjusting screw 18, the mounting frame 14 will move horizontally when the internal thread sleeve 19 is rotated. At this time, the connecting shaft 22 will pull the external hexagonal rod 21 to slide along the outer surface of the sleeve 13, which will not only not affect the adjustment function of the spacing adjustment component, but also limit the mounting frame 14;

[0053] After that, the insulating handle 1 is pulled up and down to adjust the length of the device, and then the operator can rotate the rotating sleeve 9. When the rotating sleeve 9 rotates, it will drive the inner conical tightening sleeve 10 to rotate. The inner thread tightening sleeve 10 is threadedly connected with the threaded part on the inclined surface block 11. The inner conical tightening sleeve 10 will tighten a number of inclined surface blocks, and the inclined surface blocks will be tightly pressed against the insulating tube 4, thereby positioning the length of the device;

[0054] Afterwards, the spacing between the two sets of abutting plates is adjusted by the adapting adjustment assembly. When it is necessary to adapt to the tightening of bolts of different sizes, the operator can rotate the internal threaded sleeve 43, and the internal threaded sleeve 43 is threadedly connected with the external threaded tube 42. When the internal threaded sleeve 43 is twisted, the external threaded tube 42 will move forward and backward along the axial direction of the disassembly sleeve 17, and the external threaded tube 42 will drive the tapered sleeve 37 to move forward and backward. When the tapered sleeve 37 moves forward and backward, it will drive the two sets of inclined plates 36 to move relative to each other. When the two sets of inclined plates 36 move relative to each other, they will drive their corresponding straight plates 33 When the conical sleeve 37 moves backward, the two sets of straight plates 33 will move away from each other under the action of the reset spring 40, so that the positioning of power grid bolts of different sizes can be adapted through the adaptive adjustment component, avoiding the need to match bolt sleeves of different sizes to position the current bolt, so that the two sets of abutting plates can abut against suspension wire clamp bolts of different sizes, avoiding the need to repeatedly change the bolt sleeves for positioning the suspension wire clamp bolts;

[0055] Afterwards, the disassembly sleeve 17 is closed on the outside of the power grid bolt, at which time the two sets of abutting plates are closed on the outside of the power grid bolt, and then the personnel hold the rubber hand-held sleeve 2 on the insulating hand-held rod 1, and then start the motor 7, the motor 7 cooperates with the speed controller 20 to drive the sleeve 13 to rotate, when the sleeve 13 rotates, it will drive the outer hexagonal rod 21 to rotate, when the outer hexagonal rod 21 rotates, it will drive the connecting shaft 22 to rotate, when the connecting shaft 22 rotates, it cooperates with the active bevel gear 31 and the driven bevel gear 32 to drive the disassembly sleeve 17 and the two sets of abutting plates to rotate, and then the power grid bolt can be tightened to the energized power grid, the device can have insulation through the insulating tube 4 and the insulating hand-held rod 1, improve the safety of personnel operations, and reduce the risk of climbing operations through the insulating tube 4 that can be shortened or lengthened, reduce the risk of falling from heights and electric shock, and the device can tighten bolts of different sizes, avoiding the need for multiple matching bolt sleeves to tighten power grid bolts of different sizes;

[0056] In addition, the present invention can not only conveniently tighten the loose bolts on the power grid, but also disassemble the power grid bolts that need to be disassembled. In order to prevent the power grid bolts from rusting and causing difficulty in disassembly, the external rust removal liquid can enter the insulating hand-held rod 1 through the rust removal agent inlet pipe 3 in turn, and then enter the insulating tube 4, and then enter the coil 26. The rust removal liquid then enters the external threaded tube 42 through the soft infusion tube 8, and then enters the rotary joint 46. Finally, the rust removal liquid is sprayed out through the rust removal nozzle 24. In addition, in order to improve the rust removal effect of the rust removal liquid, the electric heating tube in the heating box 25 can be started. The heat generated by the electric heating tube will be transferred to the thermal conductive silicone layer, and the thermal conductive silicone layer will transfer the heat to the rust removal liquid in the coil 26. The heated rust removal liquid will transfer the heat to the bolts on the power grid. Through the principle of thermal expansion and contraction, the bolts on the power grid will generate expansion gaps, which makes it convenient for personnel to unscrew the bolts. The present invention can not only tighten the bolts, but also unscrew the bolts, which is convenient for disassembling and assembling bolts that are difficult to disassemble.
