Description

A kind of cable core straightener

Technical field

The utility model is related to a kind of cable core straightening tool, the more precisely reality of the aligning of secondary cable core Use instrument.

Background technology

According to the requirement of standard technology, secondary screen cabinet inner cable must marshalling, numbering in substation secondary construction Clearly, without intersection, fixation must not make connect terminal block be subject to mechanical stress.Secondary cable outer protective sleeve and armouring are protected When set is peeled off and the work of follow-up core line may make secondary cable the inside core bending, in disorder, when influenceing follow-up wiring Aesthetics and accuracy.Therefore core must pull into linear being fixed on the inside of screen cabinet before wiring inside the secondary cable, this It is a very big quantities for whole wiring personnel.

At present, transformer station is newly-built or secondary improvement project in, secondary cable is laid after finishing to be needed to shell external insulation skin By core colligation after, but the core for stripping out is mostly bending, for the aesthetic property of technique, it is often necessary to manually rectify core Directly.Straightening operation is usually that staff caudad carries out smoothing out with the fingers line or clamping tail end with pliers falling on the ground with hand from one end The method beaten stretches line.Either with hand or mode is beaten the method for aligning core, easy opponent damages, in addition The mode beaten easily damages the insulated hull of core, causes insulation breakdown..

Secondary screen cabinet inner cable is generally copper core pvc sheath band-armored in transformer station, and the cable of this type is Single multicore, it is impossible to be fixed in secondary screen cabinet after cable is integrally stretched, to reach the requirement of standard technology, can only first fix Cable stretches core in cable again.

Comprise the following steps that：

1. secondary cable outer layer pvc sheath and steel-tape armouring sheath are peeled off.

2. cable end protective cover is made.

3. end is fixed on the crossbeam of secondary screen cabinet bottom

4. copper core in cable is stretched by root.

5. terminal row wiring and by core be fixed on screen cabinet inner side.

In the 4th step, because end is already fixed on the crossbeam of secondary screen cabinet bottom, narrow space in screen cabinet, only Core in cable can be stretched by root using freehand manner.

Core is copper core, soft material in secondary cable.According to the mode of hard draw, it is easy to the copper core inside damage, Copper core section is caused to diminish, injury is caused a hidden trouble to normal operation after cable, and even core can be broken when serious.Height above sea level compared with High, temperature is lower ground square, execution conditions rather harsh, if temperature is relatively low during construction, cable can be very hard.According to free-hand aligning Not only speed is slow, efficiency is low, and maximum problem is that the injury of both hands is bigger.

Utility model content

In view of above-mentioned analysis, the utility model aims to solve the problem that in narrow and small secondary screen cabinet cable before secondary cable wiring The problem that speed is slow, efficiency is low when core is aligned, while in order to protect workmen's both hands and cable core.

A kind of cable core straightener, including handle, handle connecting rod, roller, bearing have on the outer ring of the roller One or more grooves, the groove circumferentially arranges that the inside grooves are coated with rubber coating, the rubber coating Thickness is 0.1-1mm, and the groove internal diameter is more than or equal to the diameter of cable core, and the roller center has bearing, described Handle two ends are fixed with handle connecting rod, and the connecting rod is respectively fixedly connected with the both sides of bearing inner race, during hand-held handle, rolling Wheel can be rotated independently, and TRT is provided with roller, and lighting device is provided with handle, and lighting device connects with TRT Connect.

Further, there are 2 grooves on the outer ring of the roller.

Further, there is the first groove, the second groove is opened in the bottom of the first groove on the outer ring of the roller, the The diameter of two grooves is less than the first groove.A diameter of 3-15mm of first groove, a diameter of 1-5mm of the second groove.

Further, 2 grooves are set side by side with the outer ring of the roller, two diameters of groove are different.Two recessed Groove diameter is respectively 3-20mm and 1-10mm.

The utility model has the following advantages that：

It is not only laborsaving to ensure maximum protective wire in reason line process because the presence of bearing in this instrument Core.

Workmen's finger reason line is substituted by this instrument, the both hands of workmen are protected.While saving physical significantly Improve operating efficiency.

With self-generating illumination device, it is ensured that see object clearly in dark place.

Multiple grooves are set, it is ensured that the core of cable core straightener compatibility different-diameter.

Other feature and advantage of the present utility model will illustrate in the following description, also, partial from specification In become apparent, or understood by implementing the utility model.The purpose of this utility model and other advantages can pass through Specifically noted structure is realized and obtained in the specification, claims and accompanying drawing write.

Brief description of the drawings

Accompanying drawing is only used for showing the purpose of specific embodiment, and is not considered as to limitation of the present utility model, whole In accompanying drawing, identical reference symbol represents identical part.

Fig. 1 is the schematic diagram of cable core straightener.

Fig. 3 is cable core straightener side view.

Specific embodiment

Preferred embodiment of the present utility model is specifically described below in conjunction with the accompanying drawings, wherein, accompanying drawing constitutes the application one Point, and be used to explain principle of the present utility model together with embodiment of the present utility model.

A kind of cable core straightener, including handle (1), handle connecting rod (2), roller (3), bearing (4), the roller Outer ring on there are one or more grooves (5), the groove circumferentially arranges that the inside grooves are coated with rubber coating, The thickness of the rubber coating is 0.1-1mm, and the groove internal diameter is more than or equal to the diameter of cable core, the roller center With bearing, the handle two ends are fixed with handle connecting rod, and the connecting rod is respectively fixedly connected with the both sides of bearing inner race, During hand-held handle, roller can be rotated independently.2 grooves, two diameters of groove are set side by side with the outer ring of the roller It is different.

Specifically used method：

Before secondary cable wiring, each core core line has been completed, and end is fixed on the horizontal stroke for shielding cabinet bottom after increasing sheath Be placed on single core in the groove matched with core on roller when aligning by Liang Shang, core, on the other hand guiding core, pulls on the other hand The handle of straightening tool, quickly can manage the shape that is in line by cable core.Because the end of core can all cut in wiring, therefore Although the end of cable core can not manage the shape that is in line do not interfere with yet it is overall attractive in appearance.Can be according to construction after the completion of core aligning Drawing wiring, is fixed on the inner side of screen cabinet after finally core is banded together.

The above, only the utility model preferably specific embodiment, but protection domain of the present utility model is not This is confined to, any one skilled in the art can readily occur in the technical scope that the utility model is disclosed Change or replacement, should all cover within protection domain of the present utility model.
