Abstract
The utility model discloses a special hanger for disassembly and assembly of a main transformer sleeve. The special hanger comprises two same arc-shaped anchor ears, wherein one ends of the two anchor ears are connected by virtue of a swivel pin, and the other ends of the two anchor ears are provided with flexible connection components; the middle parts of the two anchor ears are provided with hoisting rings; and the inner walls of the two anchor ears are provided with liner layers. The special hanger can form an integral arc which can be unfolded and folded; in a folding state, the two anchor ears can be well fixed by virtue of the flexible connection components; the middle parts of the two anchor ears are provided with the hoisting rings which are symmetrically distributed, so that a steel wire rope can be well hung; The inner walls of the two anchor ears are provided with the liner layers, so that the steel anchor ears can be effectively prevented from damaging the insulating sleeve of a main transformer; in addition, the steel wire rope is used as a lifting rope, so that the safety coefficient is high, and further the damages, caused by lifting angle in-controllability, to the insulating sleeve due to overlarge elastic deformation of a nylon rope is also avoided; The special hanger disclosed by the utility model is simple in structure, convenient in operation, high in safety coefficient and easy in popularization and use.
Description
Technical field
The utility model belongs to the lifting device technical field, particularly a kind of main transformer sleeve pipe dismounting special hanger.
Background technology
Main transformer is the visual plant in the electric system, if find in maintenance process that the insulating tube built-in electrical insulation of voltage transformer reduces, dielectric loss exceeds standard or capacitance is when unusual, all need to use crane that insulating tube is hung oneself from voltage transformer, carry out targetedly Disintegration overhaul, with crane insulating tube is hung on the voltage transformer again after fixing and install.But because bushing for transformer is porcelain piece, in the process of dismounting, damage easily insulating tube, mostly present operational method is: adopt nylon rope when lifting, because new nylon rope intensity is large, appearance is soft, directly be bundled in nylon rope on the outside face of insulating tube and lift, can effectively avoid the damage to the insulating tube appearance; But the elasticity of nylon rope is large, and is also very large for the angle impact of lifting.Therefore adopt nylon rope lifting insulating tube can only solve the lifting rope to the damage of insulating tube, can not solve the inaccurate damage that insulating tube is caused of the lifting angle that causes owing to the nylon rope elastic deformation is excessive.And along with the increase of tenure of use and the impact of storage condition, nylon rope also can make moist, goes mouldy, disconnected strand, continue to use and all can rupture at any time, cause insulating tube to damage.The utility model provides a kind of main transformer sleeve pipe dismounting special hanger for the problems referred to above.
The utility model content
The main transformer sleeve pipe dismounting special hanger that provides a kind of coefficient easy to use, safe high is provided the utility model purpose.
To achieve these goals, the technical solution adopted in the utility model is: a kind of main transformer sleeve pipe dismounting special hanger, it comprises the anchor ear of two identical circular arcs, described two anchor ear one ends are by the connection of shipping and reselling on another market, described two anchor ear other ends arrange the flexible connection member, described two anchor ears middle part arranges suspension ring, on described two anchor ear inwalls laying is set.
Described flexible connection member comprises the connecting panel that is arranged at described anchor ear end, and described connecting panel is flexibly connected by screw bolt and nut.
Described laying is fixed by flathead screw.
The utility model comprises the anchor ear of two identical circular arcs, described two anchor ear one ends form a complete circular arc that can open, close up by the connection of shipping and reselling on another market, and described two anchor ear other ends arrange the flexible connection member, when closing up state, can well fix described two anchor ears; Described two anchor ears middle part arranges suspension ring, and two described suspension ring are symmetrical, can well articulate steel rope; On described two anchor ear inwalls laying is set, can prevent effectively that the steel anchor ear is to the damage of main transformer insulating tube, use in addition steel rope as the lifting rope, not only safety factor is high, has also avoided simultaneously causing lifting by crane the angle damage that insulating tube is caused out of control because the nylon rope elastic deformation is excessive.Described flexible connection member comprises the connecting panel that is arranged at described anchor ear end, described connecting panel is flexibly connected by screw bolt and nut, and this preferred version can well be realized opening, closing up of described anchor ear, and the bolt Joint strenght is large when closing up, and is safe.Described laying is fixed by flathead screw, can prevent the relative sliding of insulating tube, and obvolvent is stable, and can reduce changing of the relative positions damage, increases the service life.The utility model in use has two kinds of situations: when the at right angle setting insulating tube, only need on the top of bushing for transformer a described main transformer sleeve pipe dismounting special hanger to be installed, the two ends of steel rope are separately fixed on the hanging ring of both sides, utilize crane to carry out dismounting and get final product; When tilting bushing for transformer is installed, then need to be on the top of bushing for transformer and near the attachment flange place being installed respectively by a described main transformer sleeve pipe dismounting special hanger, when using the steel cable lifting, the two ends of steel rope are separately fixed on the suspension ring of two described main transformer sleeve pipe dismounting special hanger the same sides, utilizing crane to carry out dismounting gets final product, when perhaps using two steel rope liftings, the two ends of short steel cable are separately fixed on the ambilateral suspension ring of bushing for transformer top described main transformer sleeve pipe dismounting Special-purpose hanger, the two ends of long steel cable are separately fixed at bushing for transformer near on the ambilateral suspension ring of described main transformer sleeve pipe dismounting Special-purpose hanger at attachment flange place, utilize crane to carry out dismounting.No matter be to use steel cable or use two steel ropes, the lifting angle of bushing for transformer can satisfy the lifting requirement by the length of adjustment steel rope and the relative fixed position of upper and lower two special hangers.The utility model is simple in structure, easy to operate, safety factor is high, generally promotes the use of than being easier to.
Description of drawings
The utility model is further described below in conjunction with accompanying drawing:
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of main transformer sleeve pipe dismounting special hanger, it comprises the anchor ear 1 of two identical circular arcs, described two anchor ear 1 one ends are by 2 connections of shipping and reselling on another market, described two anchor ear 1 other ends arrange the flexible connection member, described two anchor ear 1 middle parts arrange suspension ring 3, on described two anchor ear 1 inwalls laying 4 are set.
