Abstract
The utility model which relates to a guard against dismounting and stealing a transformer locks and fixes the upper cover of the transformer, and the utility model is mainly composed of a lock body, an anti-theft bolt (5) and a shield body (4) for the anti-theft bolt. The lock body which adopts a split type pin coupling structure comprises an upper lock body (2), a lower lock body (9) and a pin shaft (1); the upper lock body is provided with a pin shaft hole (12), the lower lock body is provided with a corresponding pin shaft hole (13), and a pin shaft is arranged in the pin shaft hole (12) and (13). Due to the split type pin coupling structure adopted by the lock body, the distance between the upper lock body and the lower lock body is adjustable, and the utility model can adapt to the dimensional changes of the transformer in different specifications.
Description
The utility model relates to a kind of transformer loam cake that locks to prevent to tear open robber's distribution transformer anti-theft device.
For a long time, adopt common bolt connection mode between the loam cake of transformer and the shell flange always, very easily dismounting, stolen, for preventing the split robber of transformer, the application number of bulletin was 90214212.7 and was called that the patent application of " transformer anti-theft lock " provides a kind of effective anti-theft device Patent Office of the People's Republic of China on April 3rd, 1991, this anti-theft device mainly is made of lock body and anti-theft bolt, lock body is " U " font, have the bolt counter sink on the lock body, counter sink bottom has corresponding bolt hole, and the shelter of anti-theft bolt is set in the bolt counter sink.Its anti-theft bolt is a heterotypic bolt, and bolt head is asymmetric multiedge cylinder.Its shelter is slightly less than the pad money of counter sink by one and irritates wax and form; The someone utilized common tapered end to be used as the unlatching that shelter is beneficial to anti-theft device again afterwards.But this anti-theft device still has following deficiency and shortcoming: 1, because the width of lock body " U " shape groove is fixed, can not adjust, so can not adapt to the needs of plurality of specifications transformer change in size; 2, with pad money and irritate wax when making shelter, in the installation and opening process of anti-theft device, operate cumbersome, and a little less than the protection to anti-theft bolt; When 3, doing shelter with common tapered end, this tapered end subjects to artificial destruction, tapered end can not be opened, thereby the phenomenon that can cause anti-theft device not open is unfavorable for rush repair equipment.
Therefore, the purpose of this utility model is the deficiency that remedies prior art, and a kind of anti-theft device for transformer that can adapt to different size transformer size needs particularly is provided.
The purpose of utility model realizes by following mode.
The distribution transformer anti-theft device mainly is made of lock body, anti-theft bolt and anti-theft bolt shelter, has the shielding body opening and the antitheft keyhole that anti-theft bolt is set of corresponding placement shelter on the lock body.Lock body adopts split type pin draw bail, and promptly lock body is made of upper lock body, down lock body and bearing pin, has the lock shaft hole on the last down lock body, and bearing pin places in the axis hole.
The shape of bearing pin and its axis hole can be cylindrical, between bearing pin and the hole wall certain clearance is arranged, and promptly pin diameter is less than shaft hole diameter.
The anti-theft bolt shelter can adopt the fastening frame mode of screw, promptly, shelter is a metal cartridge, have groove on the side of shelter, have a screw hole on the wall of shielding body opening, be provided with trip bolt in the screw hole, the tail end of trip bolt is pressed in the groove of shelter, and trip bolt is special-shaped sunk screw.
During installation, the former plain bolt of desire peace position, lock section on the transformer is removed, to go up down lock body again and bearing pin combines, make that formed groove blocks transformer loam cake and shell flange outer between down lock body and the bearing pin, in keyhole, penetrate anti-theft bolt, in the shielding body opening, be pressed into shelter then, and tighten trip bolt with special-purpose wrench.
A significant advantage of anti-theft device provided by the utility model is, because lock body adopts split type pin draw bail, distance between upper lock body and the down lock body is adjustable, the change in size that can adapt to the different size transformer like this, can make simultaneously between anti-theft device and the transformer cooperate compact more, firmly.In addition, owing to adopt matched in clearance between bearing pin and the last down lock body axis hole, bearing pin can rotate in axis hole, makes that this axle of sawing is extremely difficult, has strengthened anti-theft effect.
The existence of anti-theft bolt shelter, the hidden concrete structure of anti-theft bolt, make special tool imitated difficult, having overcome some product simultaneously adopts common tapered end as the easy ruined shortcoming of shelter, the phenomenon of anti-theft device of not opening in the time of avoiding repairing transformer effectively takes place, and helps rush repair equipment, in addition, the installation of shelter is opened all more convenient, simple to operate.
This anti-theft device is made by certain material, and novel structure is rationally, easy to install, anti-pounding, pick-proof, anti-saw, theftproof performance is reliable, and manufacturing process is simple, with low cost, have very high performance and priceization, market prospects are wide, are the antitheft renewal products of distribution transformer.
Below in conjunction with accompanying drawing the utility model is described in detail.
Accompanying drawing 1 is the sectional view of the distribution transformer anti-theft device that provides according to the utility model, and accompanying drawing 2 is sectional views of upper lock body in the accompanying drawing 1, and accompanying drawing 3 is sectional views of down lock body in the accompanying drawing 1, and accompanying drawing 4 is sectional views of shelter in the accompanying drawing 1.
As shown in drawings, the distribution transformer anti-theft device, mainly by lock body, anti-theft bolt (5) and anti-theft bolt shelter (4) constitute, have the shielding body opening (10) of corresponding setting shelter on the lock body and the antitheft keyhole (11) of anti-theft bolt is set, lock body is by last shank (2), down lock body (9) and bearing pin (1) constitute, have axis hole (12) and (13) that bearing pin is set on the last down lock body, bearing pin places in the axis hole, constitutes a groove between last down lock body and the bearing pin, in order to block transformer loam cake (7) and shell flange outer (8), lock body is made with specific steel, and through heat treatments such as quenchings, to increase performances such as anti-pounding, anti-saw and pick-proof.
As shown in Figure 1, the shape of bearing pin (1) and axis hole (12), (13) is cylindrical, between bearing pin and the hole wall certain interval is arranged, and promptly pin diameter is less than shaft hole diameter.
Shown in accompanying drawing 1,2 and 4, shelter (4) is a metal cartridge, have groove (14) on the side of shelter, have a screw hole (15) on the wall of shielding body opening, be provided with trip bolt (6) in the screw hole, the tail end of trip bolt is pressed in the groove (14) of shelter, and trip bolt (6) is special-shaped sunk screw, has only with special-purpose wrench to turn trip bolt.
