[0031] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0032] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. 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.

[0033] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0034] The current process for dealing with the corrosion problem of railway pole crossarm bolts has the problems of complex steps, long time consumption and the need for collaboration of multiple people.

[0035] In view of this, the utility model provides a railway pole crossarm bolt removal tool, comprising: a positioning mechanism 100, a fastening mechanism 200 and a lifting mechanism 300. The positioning mechanism 100 is used to connect with the pole 001, and the lifting mechanism 300 is connected with the positioning mechanism 100. The lifting mechanism 300 is connected with the fastening mechanism 200 to drive the fastening mechanism 200 to approach or move away from the positioning mechanism 100 so that the fastening mechanism 200 is connected with the crossarm 002.

[0036] Based on the above technical solutions, the railway pole cross arm bolt removal tool provided by the utility model can achieve the following technical effects:

[0037] The railway pole cross arm bolt removal operation tool fixes the cross arm 002 during the operation by a single person operating the lifting mechanism 300 and the fastening mechanism 200, omitting the removal and restoration of the insulator binding wire, the installation and removal of the cable rope, and the repositioning of the cross arm 002. The existing process overcomes the problems of complicated steps, long time consumption, and the need for cooperation of multiple people when dealing with the rust problem of the railway pole cross arm bolts.

[0038] The following combination Figures 1 to 3 The structure and shape of the railway pole cross arm bolt removal tool provided in this embodiment are described in detail:

[0039] In an optional solution of this embodiment, the positioning mechanism 100 uses a clamp, which is sleeved on the pole 001 to provide a reliable anchor point during operation.

[0040] In an optional solution of this embodiment, the positioning mechanism 100 uses a mechanical claw, which is clamped on the outer wall of the pole 001 to provide a reliable anchor point during operation.

[0041] Regarding the structural composition of the fastening mechanism 200, specifically:

[0042] The fastening mechanism 200 includes a base 210 and a hook nail 220, and the base 210 is connected to the lifting mechanism 300. One end of the hook nail 220 is connected to the base 210, and the other end is clamped with the cross arm 002. A double nut is provided at the end of the hook nail 220 away from the cross arm 002 for locking, and a slot with an opening direction facing the base 210 is provided at the end of the hook nail 220 away from the base 210, and the hook nail 220 is clamped with the cross arm 002 through the slot. The hook nail 220 is slidably connected to the base 210, and the clamping or loosening of the cross arm 002 is controlled by the hook nail 220 approaching or moving away from the base 210. The base 210 and the cross arm 002 are respectively located on both sides of the pole 001, and two hook nails 220 are symmetrically arranged at both ends of the base 210. The base 210 , the two hooks 220 and the cross arm 002 form a ring structure surrounding the pole 001 . The movement of the cross arm 002 on the horizontal plane is limited by wrapping the pole 001 with the ring structure, thereby fixing the horizontal position of the cross arm 002 .

[0043] In order to further improve the fixing effect of the fastening mechanism 200 and the cross arm 002, in the optional solution of this embodiment, the fastening mechanism 200 also includes a synchronous beam and a guide rod, the two ends of the synchronous beam are respectively connected to the hook nail 220, the synchronous beam is perpendicular to the hook nail 220, and the synchronous beam is used to fix the relative position of the two hook nails 220 so that the two hook nails 220 can be clamped with the cross arm 002 at the same time, so as to prevent the base 210 from being deflected due to the unbalanced reaction force of the hook nail 220. The guide rod is inserted into the base 210 and vertically connected to the synchronous beam, and the guide rod is used to guide the sliding of the hook nail 220. Among them, the synchronous beam and the guide rod can be set as square tubes, round tubes or square steel.

[0044] Regarding the structural composition of the lifting mechanism 300, specifically:

[0045] The lifting mechanism 300 includes a first screw rod 310, a second screw rod 320, a sleeve 330 and a handle 340. The first screw rod 310 is connected to the positioning mechanism 100, and the second screw rod 320 is connected to the fastening mechanism 200. The first screw rod 310 and the second screw rod 320 are coaxially arranged and have opposite spiral directions. The two ends of the sleeve 330 are respectively screwed with the first screw rod 310 and the second screw rod 320, and the handle 340 is arranged in the middle of the sleeve 330.

[0046] The handle 340 is used to drive the sleeve 330 to rotate so as to control the distance between the positioning mechanism 100 and the fastening mechanism 200 by screwing the first screw rod 310 and the second screw rod 320 with the sleeve 330, so as to make the slot of the hook nail 220 abut against the lower surface of the cross arm 002 to fix the vertical height of the cross arm 002.

[0047] Furthermore, the sleeve 330 is provided with a through hole perpendicular to its own axis, and the handle 340 is inserted into the through hole. The handle 340 can slide along the through hole to switch the gripping direction to avoid interference with the pole 001 during the rotation of the sleeve 330. Among them, limit blocks are welded at both ends of the handle 340 to prevent the handle 340 from being completely separated from the sleeve 330, and protrusions are arranged at intervals on the surface of the handle 340 to achieve an anti-slip effect.

[0048] In summary, the specific working process of the railway pole crossarm bolt removal tool provided in this embodiment is as follows:

[0049] In specific application, first arrange a power outage for the working section, then install temporary seals on both ends of the line, connect the positioning mechanism 100 to the top of the pole 001, slide the hook nail 220 close to the base 210 to make the hook nail 220 and the cross arm 002 snap together, and lock the relative position of the hook nail 220 and the base 210 by double nuts. At this time, the base 210, the hook nail 220 and the cross arm 002 form a ring structure around the pole 001 to limit the movement of the cross arm 002 on the horizontal plane, thereby fixing the horizontal position of the cross arm 002.

[0050] The gripping handle 340 is used to rotate the sleeve 330, thereby controlling the distance between the positioning mechanism 100 and the fastening mechanism 200 through the screwing of the first screw rod 310 and the second screw rod 320 with the sleeve 330, and the fastening mechanism 200 is moved upward so that the slot of the hook nail 220 abuts against the lower surface of the cross arm 002 to limit the movement of the cross arm 002 in the height direction, thereby fixing the vertical height of the cross arm 002.

[0051] Remove the U-bolts and perform rust removal, painting or replacement operations, and reinstall the U-bolts to tighten the crossarm 002. Unscrew the double nuts at the hook nail 220, slide the hook nail 220 away from the base 210 to separate the hook nail 220 from the crossarm 002, disassemble the positioning mechanism 100, and finally remove the ground wire and restore power supply to the working section.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
