Abstract
The utility model relates to an instrument that is used for coil change specially, including handle and work arm, tip mutually perpendicular between them connects, the ratchet of ratchet in the tip of handle is installed install the sour jujube pole that is equipped with outer ratchet with this ratchet assorted in the ratchet, the one end of sour jujube pole is extended outside the ratchet to it to dismantle the connection to be equipped with at this tip the connecting rod of work arm, the cross section of connecting rod is regular polygon, work the arm one end be equipped with with connecting rod assorted regular polygon hole, the tip card of connecting rod is gone into the regular polygon of work arm is downthehole. The beneficial effects of the utility model are that: the rotation that the handle adopted ratchet formula rotating band to start building to do the arm just can come and go turning handle in minimum space to reach the mesh of fastening and not hard up coil bolt. The handle with work the arm for can dismantle the connection, according to the specification of coil bolt in the real work, change in good time the work arm alright, convenient and fast.
Description
Technical field
The utility model relates to power equipment maintaining field, is specifically related to a kind of instrument being specifically designed to changing of coils.
Background technology
When abnormal reduction appears in coil resistance time, need to change in time.At present in the middle of the work of more emat coil, there is following problem:
1, the Siemens switch position of coil position particularly 220kV electric pressure is higher, and longitudinal degree is large, and existing interior hexagonal hand-held tool is all shorter, and people cannot grasp, and cannot exert oneself; And Renewal process need two people to stand in double ladder or certain altitude simultaneously platform on carry out operation, have certain operating risk;
2, all coils fixed head is all that interior hexagonal screw rod is fixed, and simultaneously adjacent with top mechanism case, working space is narrow, makes interior hexagonal cannot normal rotation, brings very big inconvenience to replacing work;
3, because use conventional tool can only rotate hexagonal in 1/8 circle at every turn, make the whole dismounting of each coil and installation process want about 40 minutes nearly, so carrying out all changing of coils will take several hours, and operating efficiency is very low.
Utility model content
In sum, for solving existing technical problem, technical problem to be solved in the utility model is to provide a kind of instrument being specifically designed to changing of coils.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of instrument being specifically designed to changing of coils, comprise handle and working arm, both ends vertically connect mutually, the end of described handle is provided with the ratchet of interior ratchet, the sour jujube bar being provided with outer ratchet matched with this ratchet is installed in described ratchet, one end of described sour jujube bar is extended outside described ratchet, and is provided with the connecting rod removably connected with described working arm in this end;
The cross section of described connecting rod is regular polygon, and one end of described working arm is provided with the regular polygon hole matched with described connecting rod, and the end of described connecting rod snaps in the regular polygon hole of described working arm.
The beneficial effects of the utility model are: handle adopts ratchet-type to rotate the rotation driving working arm, just can come and go turning handle, thus reach the object of fastening and loosening coil bolt in minimum space.And handle and working arm are for removably connecting, according to the specification of real work coil bolt, change in good time working arm just can, convenient and swift.
Further, described handle is the arc surface of outwardly convex away from one end of described working arm, and on this arc surface, be provided with the interlaced lines increasing frictional force.
Above-mentioned further beneficial effect is: arc surface is handgrip part, can increase the frictional force between finger and handle, avoids skidding between finger and handle.
Further, described sour jujube bar and described connecting rod one-body molded.
Further, the length of described working arm is 72mm.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
In accompanying drawing, the list of parts representated by each label is as follows:
1, handle, 2, working arm, 3, ratchet, 4, sour jujube bar, 5, connecting rod, 6, arc surface.
Detailed description of the invention
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As shown in Figure 1, a kind of instrument being specifically designed to changing of coils, comprise handle 1 and working arm 2, both ends vertically connect mutually, according to measurement working space, thus draw the design size of hand-held tool, preferred: the length of described working arm 2 is 72mm.The end of described handle 1 is provided with the ratchet 3 of interior ratchet, the sour jujube bar 4 being provided with outer ratchet matched with this ratchet 3 is installed in described ratchet 3, one end of described sour jujube bar 4 is extended outside described ratchet 3, and is provided with the connecting rod 5 of the described working arm 2 that removably connects in this end.Removably connect and be specially: the cross section of described connecting rod 5 is regular polygon, one end of described working arm 2 is provided with the regular polygon hole matched with described connecting rod 5, the end of described connecting rod 5 snaps in the regular polygon hole of described working arm 2, preferred: described sour jujube bar 4 is one-body molded with described connecting rod 5.Handle 1 adopts ratchet-type to rotate the rotation driving working arm 2, just can come and go turning handle 1, thus reach the object of fastening and loosening coil bolt in minimum space.And handle 1 and working arm 2 are for removably connecting, according to the specification of real work coil bolt, change in good time working arm 2 just can, convenient and swift.
Described handle 1 is the arc surface 6 of outwardly convex away from one end of described working arm 2, and on this arc surface 6, be provided with the interlaced lines increasing frictional force.Arc surface 6 is handgrip part, can increase the frictional force between finger and handle 1, avoids skidding between finger and handle 1.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
