Description

Power transformer safe antitheft vibration abatement

(1) technical field

The utility model relates to power transformer safe antitheft vibration abatement.

(2) background technology

The stolen situation of transformer constantly takes place, and brings very big hidden danger to electric power netting safe running, so also occurred some anti-theft product on the market, is the anti-theft lock that prevents that the transformer loam cake from being left basically, has prevented that effectively loam cake copper core is stolen.But a lot of robbers do not know to lock, and feel about in the dark evening and just transformer are pushed from stand, and such situation is a lot of local generations.Though it is stolen that transformer copper core does not have, transformer is translated into from the stand underground, and this transformer has also just been scrapped so, and loss is stolen the same with transformer for operation of power networks.Also some places adopt the way of the dead stand channel-section steel of weldering, but arrived under the situations such as maintenance, increase-volume or external taxi, a kind of flagrant obstacle of transformer weldering extremely just becoming, translated into underground in order to prevent transformer from stand by the robber, can allow electric power enterprise conveniently overhaul and business change again, thereby develop the power transformer safety theftproof device.

(3) summary of the invention

Problem to be solved in the utility model is exactly to provide a kind of device that can protect transformer safety at above deficiency.Its technical scheme is as follows:

It comprises anti-theft anchor ear, chain, circular tapered end, arc tapered end and lock body, and anti-theft anchor ear is connected by circular tapered end by chain with lock body.Lock body one end is a connecting plate, has lockhole on the connecting plate, and car has internal thread in lockhole, and the lock body other end is a U type Connection Block; Circular tapered end comprises lock housing and is positioned at anti-theft bolt, the plug of lock housing.The arc tapered end comprises U-shape lock seat, lock housing and plug, the U-shape lock seat has upper and lower platform, has lock housing on the upper mounting plate of U-shape lock seat, have anti-theft bolt and plug in the lock housing, on the lower platform of U-shape lock seat, have limit chamber, the screw end head of anti-theft bolt has a block, and block is positioned at limit chamber.

Compared with prior art the utlity model has following beneficial effect:

The utility model pins transformer with circular tapered end by lock body, lock body is locked on the electric pole by chain and anti-theft anchor ear again, with the arc tapered end transformer cover is pinned, because the special construction of circular tapered end and arc tapered end, need plug opener by special use, could take out plug from anti-theft lock end, use specific purpose tool to take out anti-theft bolt then, whole device has anti-saw, pick-proof, antirust, anti-function such as pound, both prevented that transformer from being translated into underground by the robber from stand, can allow electric power enterprise conveniently overhaul and business change again, thereby guarantee the safety of power transformer, safeguard the economic interests of electric power enterprise.Steel link chain is made through the steel of special thermal treatment PROCESS FOR TREATMENT, and steel link chain has very strong pliability, thereby has very strong shockproof effect.

(5) embodiment

Referring to Fig. 1-Fig. 3, the utility model comprises anti-theft anchor ear 4, chain 3, circular tapered end 2, arc tapered end and lock body 1, and anti-theft anchor ear 4 is connected by circular tapered end 2 by chain 3 with lock body 1.Lock body 1 is a T type lock body, and an end is a connecting plate, has lockhole 17 on the connecting plate, car has internal thread in lockhole 17, has installing hole 6 at the connecting plate two ends of lock body 1, and installing hole 6 is a strip, be convenient to lock body and adapt to the installation site on transformer, lock body 1 other end is a U type Connection Block 5.Circular tapered end 2 comprises lock housing 12.1 and is positioned at anti-theft bolt 13.1, the plug 10.1 of lock housing, plug 10.1 is positioned at the top of anti-theft bolt 13.1, the plug center has through hole and car has internal thread, and have with the through hole coupling of externally threaded plug 8 with the plug center, above lock housing inner ring anti-theft bolt, has a boss 11, plug is played position-limiting action, edge, lock housing lower end has a limiting stand 14, anti-theft bolt is played position-limiting action, and the center on the center on anti-theft bolt top and plug top has the groove of unblanking 9.1,9.2.The arc tapered end comprises U-shape lock seat 15, lock housing 12.2 and plug 10.2, U-shape lock seat 15 has upper and lower platform, has lock housing 12.2 on the upper mounting plate of U-shape lock seat 15, have anti-theft bolt 13.2 and plug 10.2 in the lock housing, plug 10.2 is positioned at the top of anti-theft bolt 13.2, on the lower platform of U-shape lock seat 15, have limit chamber, the screw end head of anti-theft bolt 13.2 has a block 16, block 16 has through hole and car has the screw rod of internal thread and anti-theft bolt 13.2 to mate, the shape of block 16 and limit chamber shape adapt to, and block 16 is positioned at limit chamber.

The utility model adopts the steel of special thermal treatment PROCESS FOR TREATMENT to make, the special-purpose unlocking tool that needs the preparation and the groove 9.1,9.2 of unblanking to mate, and the shape of this instrument termination is corresponding with the shape of the groove of unblanking, similar nut and tapping cutter.At first two anti-theft anchor ears 4 are installed in electric pole and the flat horizontal place of transformer cover respectively during use, pin the anti-theft bolt 13.1 of anti-theft anchor ear 4 respectively by four circular tapered ends 2, chain 2 one ends connect anti-theft anchor ear 4, and the other end is connected with the U type Connection Block 5 of lock body 1 by circular tapered end 2.When lock body 1 is connected with transformer, take out anti-theft bolt 13.1, it is dropped in the lock housing 12.1, screw rod is passed hole on the transformer cover, pass the lockhole 17 on the lock body 1 again, because lockhole 17 and screw rod coupling, utilize unlocking tool that anti-theft bolt 13.1 is screwed, plug 10.1 is beaten in the lock housing 12.1, plug 8 on the car again, covered lock housing lid 7 just.Because screw rod just is no more than lockhole, unlocking tool is a non-standard component, so the robber can't open tapered end.Circular tapered end using method on anti-theft anchor ear 4 and the U type Connection Block 5 in like manner.The arc tapered end then pins transformer cover two ends, and use just needs to come pick-proof with block 16 with circular tapered end.

When needing the dismounting anti-theft device for transformer, need to take out plug from tapered end, use special-purpose unlocking tool to take out anti-theft bolt then, thereby power transformer is separated with anti-theft device with above-mentioned special-purpose unlocking tool.
