Description

Technical Field

[0001] The invention relates to the technical field of grounding wire hanging and removing, in particular to a grounding wire hanging and removing device for electric power maintenance. Background Art

[0002] Line maintenance refers to the work carried out on power transmission lines based on problems found during inspections, tests, and tests, aimed at eliminating defects, improving equipment health, preventing accidents, and ensuring safe operation of the lines. Before conducting power maintenance, it is first necessary to install the grounding wire to ensure the safety of the workers during the maintenance process.

[0003] In the prior art, for example, a grounding wire hanging and removing device for power maintenance is provided with publication number CN118315887A, which specifically relates to the technical field of grounding wire hanging and removing equipment, including a hook, two clamping rods are arranged inside the hook, two coil springs are arranged inside the hook, a terminal is arranged on one side of the hook, an adjusting device is arranged on one side of the hook, the adjusting device includes a connecting block and a handle, a limiting device is arranged on one side of the connecting block, a supporting device is arranged on one side of the handle, the connecting block is fixedly connected to the hook, a screw is fixedly connected to one side of the connecting block, a threaded tube is threadedly connected to the surface of the screw, and a slot is provided on one side of the threaded tube. By setting the adjusting device, the use distance of the hook can be increased, reducing the need for personnel to lean forward or sideways when hanging the hook at a long distance, which causes dangerous operation and difficulty in hooking, thereby improving the convenience and efficiency of personnel hanging and removing the grounding wire.

[0004] The above-mentioned prior art reduces the angle of the worker's body leaning forward when hanging the grounding wire by adjusting the use distance of the hook through a thread. Adjusting the hanging distance adapted to the hook in this way will increase the adjustment workload of the worker when hanging the grounding wire. Since the grounding wire is connected to the hook, when the extension distance of the hook needs to be adjusted, it is necessary to adjust it by rotating the telescopic rod. When the adjustment distance is long, the worker needs to rotate it continuously for a long time. Since there are regulatory requirements for the spacing between two cables when the cables are installed, the adjustment length can be adjusted in multiple levels within a range. Moreover, the above-mentioned prior art only considers hanging on the cable, and the cable is usually in a flat state. When inspecting the railway contact network line, the hook can be hung on the inclined wrist arm of the contact network support or the contact network line. The above-mentioned prior art does not take into account the situation when it needs to be hung on the inclined wrist arm of the contact network support. Summary of the invention

DETAILED DESCRIPTION

[0037] The following is combined with Figure 1-Figure 12 The present invention is described in further detail.

[0038] The embodiment of the present invention discloses a grounding wire hanging and removing device for electric power maintenance, which can adapt to the hanging and removing work of the grounding wire in different position states, and can perform secondary tightening on the hanging position to ensure the stability of the connection at the hanging position, so as to maximize the effect of the grounding wire.

[0039] Reference Figure 1 A ground wire hanging and removing device for power maintenance, comprising a hanging hook 1, the inner side of the hanging hook 1 is elastically hinged with two left-right symmetrical clamping plates 3 for clamping on the contact network line, an auxiliary mechanism 2 for adapting to the inclined clamping position is arranged at the middle position of the inner side of the hanging hook 1, a secondary clamping mechanism 5 for secondary clamping is arranged on the right side of the clamping plate 3, a connecting mechanism 6 is arranged on the right side of the hanging hook 1 and below the secondary clamping mechanism 5, an adjusting mechanism 7 is arranged on the right side of the connecting mechanism 6, and a ground wire connecting sleeve 4 is fixedly installed on the front surface of the hanging hook 1.

[0040] In this case, the retractable setting of the adjustment mechanism 7 and the adjustment of the angle of the hanging hook 1 on the connecting mechanism 6 can make it more convenient to hang and remove the grounding wire, and the setting of the auxiliary mechanism 2 can adapt to the hanging and removing of the grounding wire in different positions, which can further ensure the safety of the operators and make the hanging and removing of the grounding wire easier.

[0041] In this case, by setting the stabilizing member 72, after the grounding wire is hung and removed, when wind acts on the telescopic member 71, the force generated by the swing of the telescopic member 71 can be applied to the hanging position of the hanging hook 1 as small as possible, making the hanging position more stable to ensure the normal operation of the grounding wire.

[0042] In this case, by setting up the auxiliary mechanism 2, the grounding wire can be hung and removed in both a flat position and an inclined position, and at the same time, the grounding wire can be connected to the hanging position with a larger area, so that the grounding wire can be fully connected to the hanging position.

[0043] In this case, the secondary clamping mechanism 5 is provided to fix the hanging position for a second time after the hanging hook 1 is hung at the specified position, so as to ensure that the hanging hook 1 is more stable at the hanging position, so that the hanging hook 1 can be more firmly connected to the hanging position through the clamping plate 3, so as to maximize the grounding effect of the grounding wire.

[0044] Reference Figure 1 , Figure 2 and Figure 3 The auxiliary mechanism 2 includes a limit piece 21 arranged on the hanging hook 1, an adapter piece 22 is arranged on the inner top of the hanging hook 1, the limit piece 21 also includes a linkage shaft 214 that penetrates front and back and is rotatably connected to the top of the front surface of the hanging hook 1, and the front and rear surfaces of the linkage shaft 214 are fixedly connected with an adjusting screw 215, and the front and rear surfaces of the hanging hook 1 and the right side of the linkage shaft 214 are fixedly connected with a fixed connecting rod 211, and a connecting adjustment piece 213 is slidably connected to the fixed connecting rod 211, and the connecting adjustment piece 213 is threadedly connected to the corresponding adjusting screw 215, and the left sides of the opposite surfaces of the two connecting adjustment pieces 213 are fixedly connected with a limit rod 212.

[0045] Reference Figure 2 and Figure 4 The adapter 22 includes a mounting groove 221 formed on the inner wall of the top of the hanging hook 1. Two elastic telescopic connecting rods 222 symmetrically arranged front and rear are hingedly connected inside the mounting groove 221. The bottom ends of the two elastic telescopic connecting rods 222 are hingedly connected with a connecting arc piece 223.

[0046] Reference Figure 2The connecting mechanism 6 includes two front-to-back symmetrical hinge seats 64 fixedly connected to the right side of the hanging hook 1, and a connecting shell 62 is hinged between the opposite surfaces of the two hinge seats 64. The connecting shell 62 and the hinge seat 64 are frictionally matched. The shape of the connecting shell 62 is a combination of a left rectangular block and a right cylinder, and a connecting piece 61 is arranged on the connecting shell 62.

[0047] During specific use, first adjust the hanging hook 1 on the connecting shell 62 to a vertical position with the connecting shell 62, then connect the grounding wire to the grounding wire connecting sleeve 4, and ground the other end of the grounding wire. When encountering an inclined hanging position, adjust the position of the connecting adjustment piece 213 on the fixed connecting rod 211 by rotating the adjusting screw 215 on the front side. At the same time, the connecting adjustment piece 213 on the rear side moves in the same direction as the connecting adjustment piece 213 on the front side, and cooperates with the limiting rod 212 to adapt the inclination angle of the elastic telescopic connecting rod 222 to the hanging position limit. When the hanging hook 1 is hung in an inclined position, the lower side of the connecting arc piece 223 contacts the hanging position. At the same time, cooperate with the two elastic telescopic connecting rods 222 to contract and deflect on the hanging hook 1, so that the connecting arc piece 223 can become the same inclination angle as the hanging position, making it more stable in the inclined hanging position and reducing shaking.

[0048] Reference Figure 1 , Figure 2 and Figure 5 The secondary clamping mechanism 5 includes two symmetrical adjusting members 51 arranged on the front and rear surfaces of the hanging hook 1, and a linkage member 52 is commonly arranged on the right side of the two adjusting members 51. The adjusting member 51 also includes an adjusting slide 511 fixedly connected to the hanging hook 1, and a connecting sleeve 514 is slidably connected to the inside of the adjusting slide 511 up and down, and the connecting sleeve 514 and the adjusting slide 511 are kept relatively fixed by fastening bolts.

[0049] Reference Figure 2 and Figure 5 The connecting sleeve 514 is internally connected to a clamping plate 516 for forward and backward sliding movement. The upper surface of the left end of the clamping plate 516 is an arc surface and is rotatably connected to a plurality of auxiliary rollers 517. The upper surface of the connecting sleeve 514 is fixedly connected to a fixed seat 515. The front surface of the fixed seat 515 is fixedly connected to an auxiliary sliding rod 512. A connecting piece 513 is slidably connected to the circumferential surface of the auxiliary sliding rod 512. The bottom end of the connecting piece 513 is fixedly connected to the right end of the upper surface of the clamping plate 516. A connecting spring is sleeved on the circumferential surface of the auxiliary sliding rod 512 and is located between the fixed seat 515 and the connecting piece 513.

[0050] Reference Figure 2 and Figure 5The linkage member 52 includes a fixing plate 523 to which the right ends of the two clamping plates 516 are fixedly connected. A pulley block 522 is fixedly connected to the right side of the hanging hook 1 and below the fixing plate 523 . A pull rope 521 is fixedly connected to the left side of the fixing plate 523 .

[0051] During specific use, before hanging, the position of the connecting sleeve 514 on the adjusting slide 511 is adjusted according to the hanging position, so that the arc top position of the arc surface of the clamping plate 516 is slightly higher than the bottom end of the hanging position, and then the connecting sleeve 514 is kept fixed on the adjusting slide 511 by tightening the bolts, and the two connecting sleeves 514 are driven to move synchronously inside their corresponding adjusting slides 511 through the fixing plate 523.

[0052] Reference Figure 1 , Figure 2 , Figure 6 and Fig.12 The adjustment mechanism 7 includes a fixing member 72 arranged on the right side of the connecting mechanism 6, a telescopic member 71 is arranged on the right side of the fixing member 72, and the telescopic member 71 also includes a sliding insulating rod 711 fixedly connected to the right side of the fixing member 72, and a fixed insulating rod 712 is slidably connected to the right side of the circumferential surface of the sliding insulating rod 711, and two vertically symmetrical placement grooves 713 are provided at the right end of the circumferential surface of the sliding insulating rod 711, and a second elastic telescopic connecting seat 714 is fixedly installed inside the placement groove 713, and a plurality of groups of left-right distributed limiting holes are provided on the circumferential surface of the fixed insulating rod 712, and each group of limiting holes is symmetrically arranged in an upward and downward manner, and the end of the second elastic telescopic connecting seat 714 away from the axis of the sliding insulating rod 711 is spherical and matches the limiting holes on the fixed insulating rod 712.

[0053] During specific use, after completing the position adjustment of the clamping plate 516, at this time, according to the distance between the hanging position of the hanging hook 1 and the staff, the sliding insulating rod 711 is pulled to slide inside the fixed insulating rod 712 to adjust the common length of the sliding insulating rod 711 and the fixed insulating rod 712 to adapt to the clamping position at different distances from the staff. After the adjustment is completed, the top end of the second elastic telescopic connecting seat 714 is clamped in the limiting hole on the fixed insulating rod 712 to keep the sliding insulating rod 711 and the fixed insulating rod 712 relatively fixed.

[0054] After the common length adjustment between the fixed insulating rod 712 and the sliding insulating rod 711 is completed, the staff now holds the bottom end of the fixed insulating rod 712 to hang the hanging hook 1 at the hanging position, and after the hanging hook 1 is firmly hung with the connecting arc piece 223, the staff now cancels the grip of the fixed insulating rod 712. At this time, under the action of its own gravity, the fixed insulating rod 712 changes from a horizontal state to a vertical state. At the same time, the sliding insulating rod 711 drives the connecting shell 62 to rotate on the hinge seat 64 through the connecting piece 61, generating a pulling force on the pull rope 521, pulling The rope 521 changes direction through the pulley group 522 to generate a leftward pulling force on the fixed plate 523, pushing the clamping plate 516 to slide to the left inside the connecting sleeve 514. At the same time, the connecting piece 513 slides to the left on the auxiliary sliding rod 512 and compresses the connecting spring. At this time, the arc surface of the clamping plate 516 contacts the bottom end of the hanging position, and cooperates with the elastic force of the elastic telescopic connecting rod 222 itself to clamp the hanging position for the second time. The auxiliary roller 517 can be set to make the clamping plate 516 and the bottom end of the hanging position slide more smoothly, and the hanging work is completed at this time.

[0055] Reference Figure 2 and Figure 7 The stabilizing member 72 includes a fixed shell 721 fixedly connected to the right side of the connecting member 61. The right side of the fixed shell 721 is opened. A plurality of limit springs 722 are distributed in a circular array on the inner circumferential surface of the fixed shell 721. One end of the plurality of limit springs 722 close to the axis of the fixed shell 721 is commonly fixedly connected with a connecting block 723. The left side surface of the connecting block 723 is slidably connected to the right inner wall of the fixed shell 721, and the right side surface of the connecting block 723 is fixedly connected to the left side surface of the sliding insulating rod 711.

[0056] During specific use, after the hanging hook 1 is hung at the hanging position, the fixed insulating rod 712 is in a vertical state. When the fixed insulating rod 712 is shaken by wind, the shaking force of the fixed insulating rod 712 acts on the connecting block 723. At this time, the connecting block 723 drives the limiting spring 722 to shake on the fixed shell 721. With the elastic force of the limiting spring 722 itself, part of the force generated by the shaking of the fixed insulating rod 712 can be offset, so that the force generated by the shaking of the fixed insulating rod 712 acts on the hanging hook 1 as little as possible, making the hanging hook 1 more stable in the hanging position.

[0057] Reference Figure 2 , Figure 7 , Figure 8 and Fig. 9The connecting member 61 includes a fixed cylinder 611 which is slidably connected to the cylindrical position of the connecting shell 62. A plurality of splines which correspond to the key grooves at the left end of the fixed cylinder 611 are arranged in a circular array on the circumferential surface of the cylindrical position of the connecting shell 62. A sliding track 615 is fixedly connected to the right side surface of the connecting shell 62. A plurality of sliding blocks 614 which are distributed in a circular array are slidably connected to the sliding track 615. A telescopic pull rod 616 is fixedly connected to the right side surface of the sliding block 614.

[0058] Reference Figure 2 , Figure 7 , Figure 8 and Fig. 9 The right end of the telescopic pull rod 616 is slidably connected to the limit pull rod 617, and a limit groove for limiting the sliding distance of the telescopic pull rod 616 is opened on the limit pull rod 617. The right end of the limit pull rod 617 is fixedly connected to the left side of the fixed shell 721. The right side of the connecting shell 62 is rotatably connected with the spline sleeve 613. The left end of the spline sleeve 613 penetrates into the interior of the connecting shell 62. The right end of the spline sleeve 613 is slidably connected with the spline shaft 612. The right end of the spline shaft 612 is fixedly connected to the left side of the fixed shell 721. The end of the pull rope 521 away from the fixed plate 523 passes around the pulley group 522 and is fixedly connected to the circumferential surface of the spline sleeve 613.

[0059] Reference Figure 2 , Fig.10 and Fig.11 A locking piece 63 cooperating with the connecting shell 62 is provided on the outer wall of the fixed cylinder 611, which is used to limit the rotation and left and right movement of the fixed cylinder 611. Specifically, the locking piece 63 includes three limit pins 634 evenly distributed on the lower and upper parts of the circumferential surface of the fixed cylinder 611. The limit pin 634 is fixedly connected to the limit baffle 633 on the side away from the fixed cylinder 611. The limit pin 634 is provided with grooves on two surfaces symmetrical with respect to the radial direction of the fixed cylinder 611. The connecting shell 62 is fixedly connected with a fixing column 631 at the position corresponding to the limit pin 634. The fixing column 631 is provided with a clamping hole 635 that runs through the left and right and is adapted to the limit pin 634. The upper and lower inner walls of the clamping hole 635 are embedded and fixedly connected with a first elastic telescopic connecting seat 636. The opposite surfaces of the two first elastic telescopic connecting seats 636 are both spherically set and adapted to the groove on the limit pin 634.

[0060] When the locking cam 630 is in the locked state, the locking cam 632 is in the locked state, and the locking cam 632 is in the locked state, so that the locking cam 632 is locked.

[0061] At this time, rotating the fixed insulating rod 712 drives the fixed cylinder 611 to rotate on the connecting shell 62. At the same time, the fixed shell 721 cooperates with the auxiliary sliding rod 512 to drive the connecting piece 513 to rotate on the connecting shell 62, and the pull rope 521 wrapped thereon is loosened. At this time, the pull rope 521 is loose and no longer generates tension on the fixed plate 523. Under the action of the elastic force of the connecting spring itself, the clamping plate 516 is restored to its original position on the connecting sleeve 514. At the same time, during the rotation process, the fixed shell 721 drives the sliding block 614 to rotate on the sliding track 615 through the limiting pull rod 617 and the telescopic pull rod 616 to ensure that the fixed shell 721 rotates smoothly when limited in the left and right directions, thereby canceling the secondary clamping of the hanging position. Then the staff removes the hanging hook 1 from the hanging position to complete the dismantling work.

[0062] It should be noted that when adjusting the upper and lower positions of the connecting sleeve 514, after the adjustment is completed, the spline sleeve 613 is driven to rotate on the connecting shell 62 through the fixed cylinder 611 in cooperation with the spline shaft 612 to keep the pull rope 521 in a taut state, and then the fixed cylinder 611 is re-engaged on the spline on the connecting shell 62, and at the same time, the limit pin 634 is extended into the interior of the engaging hole 635, and the spherical end of the first elastic telescopic connecting seat 636 is abutted against the fixed column 631 to limit the position of the limit pin 634 on the fixed column 631. At the same time, through the setting of the limit baffle 633, the distance that the limit pin 634 extends into the interior of the engaging hole 635 can be limited, so that the first elastic telescopic connecting seat 636 can be smoothly engaged with the interior of the fixed column 631.

[0063] The present invention can carry out ground wire hanging at hanging positions of different position states, by fitting the connecting arc piece 223 at the hanging position, cooperating with the elastic telescopic connecting rod 222 to match the inclination of the installation position in the installation groove 221 for rotation, and at the same time, the elastic telescopic connecting rod 222 itself extends and contracts to adjust the connecting arc piece 223 to adapt to the hanging position; and by adjusting the extension length of the sliding insulating rod 711 on the fixed insulating rod 712, the hanging position can be conveniently adapted, and at the same time, the hanging hook 1 is rotated on the hinge seat 64, so that the opening of the hanging hook 1 can be perpendicular to the sliding insulating rod 711. During the hanging process, it is only necessary to translate the sliding insulating rod 711 to below the hanging position, and then adjust the position of the hanging hook 1 up and down to complete the hanging work, making the hanging work of the staff easier, and holding the sliding insulating rod 711 horizontally reduces the working radius when holding the sliding insulating rod 711 vertically, further ensuring the hanging safety of the staff, avoiding the situation of accidental touch, and further improving the scope of application of the present invention.

[0064] The implementation principle of the present invention is as follows: (1) first connect the ground wire to the ground wire connecting sleeve 4, then perform a grounding operation on the other end of the ground wire, then the staff adjusts the telescopic length of the telescopic member 71 according to the hanging position, and then the staff hangs the hanging hook 1 on the inclined arm of the contact network support or the contact network line through the telescopic member 71.

[0065] (2) By setting the adapter 22, the hanging hook 1 can adapt to a flat or inclined hanging position, and then the hanging hook 1 is clamped at the hanging position by the clamping plate 3, and the grounding wire is connected to the hanging position to achieve the grounding operation.

[0066] (3) At this time, the staff releases the telescopic member 71. Under the action of its own gravity, the telescopic member 71 changes from a horizontal state to a vertical state. The telescopic member 71 simultaneously drives the connecting member 61 and the connecting shell 62 to rotate on the hinge seat 64, and pushes the adjusting member 51 through the linkage member 52 to perform secondary clamping on the hanging position of the hanging hook 1, thereby completing the hanging work.

[0067] (4) When the operation is completed, a downward pulling force is applied to the telescopic member 71. At this time, the locking member 63 cancels the limit on the connecting member 61. By rotating the telescopic member 71 to cooperate with the connecting member 61, a rightward pulling force is generated on the linkage member 52, thereby canceling the secondary clamping of the hanging position. Then the staff removes the hanging hook 1 from the hanging position to complete the dismantling work.

[0068] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
