Description
Technical field
The utility model relates to construction of transformer substation field, particularly, the utility model relates to a kind of thread hook hang device carrying out charged payingoff construction for crossing over tube type bus in transformer station, and described line hook is provided with a kind of easy to operate, reliable coaster pull rope locking mechanism.
Background technology
In transformer station, use tube type bus more.At home in the electrical network of certain areas, outdoor power distribution unit has started to adopt tube type bus.
Meanwhile, in transformer station above tube type bus, also often must spreading conducting wire.
In the past, above leap tube type bus, spreading conducting wire often adopted power cut construction method.And power cut construction method easily causes the mass lesions of tube type bus and wire.In addition, adopt in transformer station and cross over cast bus belt electricity line laying work, direct contact on tube type bus was carried out in the past.Thus, the mass lesions of tube type bus and wire is also easily caused.
Now existing a kind of double bundle conductor double-end pulley is applicable to cross over cast bus belt electric line laying work use transformer station in, and above-mentioned double bundle conductor double-end pulley can not power cut construction, can not cause the mass lesions of tube type bus and wire.
Double-end pulley, when car uses, is suspended on pull rope (load) by described existing two-conductor line double-end pulley; Be provided with pull rope support portion (hole) in the middle part of it, its underpart is provided with two unfolding conductor hook portions.Single conductor is placed on two unfolding conductor hook portions.Drag pull rope, wire can synchronously be followed double-end pulley and be moved.
On pull rope, hang a double-end pulley every 2 meters, guarantee the single conductor safe distance that operating tube type bus is enough with below all the time.Thus under realizing the state that pipe bus normally runs in transformer station, cross over charged bus spreading conducting wire.
But the shortcoming of existing above-mentioned two-conductor line double-end pulley is, because wire weight is larger, on the other hand, for supporting pull rope, less for placing with described pull rope support portion (hole) opening part of drag rope, simultaneously, drag rope rough surface, in distraction procedure, traction force all becomes a larger angle with described above-mentioned wire coaster usually, therefore, in distraction procedure, often there is the damping because the opening part of drag rope changes and cause pull rope to block, wasting time and energy, affect efficiency of construction.In addition, if described pull rope support portion (hole) opening part is comparatively large, then draws shakiness, and cause drag rope easily to come off.
With this, this area requires a kind of two-conductor line double-end pulley, described two-conductor line double-end pulley has elastic anchorage force and chucking power for the described pull rope support portion (hole) of placing and drawing two ropes, in distraction procedure, the damping because the opening part of drag rope changes can not be there is and cause pull rope to block, waste time and energy, affect efficiency of construction.In addition, require that described pull rope is not easy to come off at support portion (hole) opening part.
Utility model content
The technical problems to be solved in the utility model is, provides a kind of easy to operate two-conductor line double-end pulley hook.Described two-conductor line double-end pulley hook can be easy to open, be beneficial to wire to deviate from, described two-conductor line double-end pulley hook is provided with pull rope locking mechanism, the pull rope of described two-conductor line double-end pulley hook can be made to be subject to a flexible restraining force in use, when there is the damping changed because of the opening part of drag rope in distraction procedure, drag rope can produce at this position to shift flexibly and keep traction unimpeded, be unlikely to because this damping causes rope to block, time saving and energy saving, improve efficiency of construction.
The technical solution of the utility model is as follows:
An easy to operate described two-conductor line double-end pulley hook, comprises hook body, and the opening hook hole of described hook body upper part and bottom are two opening trough_like through holes of double end shape; Be provided with open type traction cord hole in the middle part of described two-conductor line double-end pulley hook, described opening trough_like through hole is provided with the peristome for loading and unloading wire, during use, wire is positioned at flute profile position, it is characterized in that,
Open type traction cord hole side in the middle part of described two-conductor line double-end pulley hook arranges pull rope locking mechanism,
Described pull rope locking mechanism comprises:
Be bolted in coaster body, for locating, locking the bolt of pull rope,
With described bolted pressing plate, promote by described pressing plate, for locating, locking the removable tight lock part of pull rope,
Spring is provided with between described pressing plate and removable tight lock part,
The pull rope contact site of described removable tight lock part is the sheet of downside hook-type.
After putting into pull rope in described upper groove, swivel bolt, namely carries out flexible positioning and locking by connected pressing plate, spring and removable tight lock part to pull rope.
Thus, be unlikely to because wire weight is larger, or because of less for placing with described pull rope support portion (hole) opening part of drag rope, meanwhile, due to drag rope rough surface, or in distraction procedure, tractive effort becomes a larger angle with described above-mentioned wire coaster, thus, cause the open type traction cord hole place because of drag rope change greatly damping and drag rope is blocked, waste time and energy, affect efficiency of construction.
According to a kind of easy to operate two-conductor line double-end pulley hook of the present utility model, it is characterized in that,
Described removable tight lock part is made up of with the latch segment be fixedly connected with on it slide block, and the pull rope contact site of described latch segment is the sheet of downside hook-type.
According to a kind of easy to operate two-conductor line double-end pulley hook of the present utility model, it is characterized in that, the pull rope contact site of described latch segment is curved.
Thus, can make described pull rope in distraction procedure, be unlikely to because gravity is comparatively large or diameter is less, pull rope comes off described open type traction cord hole.
According to a kind of easy to operate two-conductor line double-end pulley hook of the present utility model, it is characterized in that, described bolt and pressing plate screw thread are spirally connected.
According to the utility model, the openable double-end pulley in described opening hook portion uses or shirks and need not unload bolt, and replacement part is very convenient, in addition, described two adjacent lead channels grooves are circular section groove, thus, can reduce in rope and wire moving process and rub.
According to easy to operate bullhead thread hook hang device of the present utility model, it can be high-strength aluminum alloy manufacture.Thus, make easy to operate bullhead thread hook hang device of the present utility model lightweight, convenient operation, conveyance.
In addition, hook of the present utility model is applicable to cross over cast bus belt electricity line laying work use in transformer station, can not power cut construction, can unfold two wires simultaneously; The mass lesions of tube type bus and wire can not be caused.In addition, this hook is simple, easy to operate, safe and reliable.
