Abstract
The utility model discloses a kind of power cable inner core straightening device, comprise a L bracket, described support one end arranges wire clamp, the other end arranges fixed pulley, and described support is hinged with single-handle type drawtongs by connecting rod.Cable internal core wire to be straightened is got one and is walked around pulley and put into jaw inside, hold with a firm grip handle and bracing frame, stressed along with handle, and cable internal core wire end around binding clip axis of rotation, and then is clamped by jaw by lower side handle; When continuation increase grip holds handle with a firm grip, single-handle type drawtongs is overall around supporting the axis of rotation added, thus drives heart yearn end that internal core wire is stretching by binding clip.The utility model is simple and practical, simple to operate, laborsaving, drastically increases the operating efficiency of stretching cable inner core in cable laying construction, the unnecessary damage caused surrounding devices and cable when avoiding bracing wire.
Description
Technical field
The utility model relates to power cable technical field of construction equipment, particularly relates to the stretching specific purpose tool of power cable inner core.
Background technology
Along with the fast development of national economy, newly-built transformer station of State Grid Corporation of China quantity is also in continuous increase, and electric equipment is also being on the increase, and needs the power cable laid to roll up thereupon.In the construction operation of power cable, the inner core of power cable, before access device, for the ease of winding displacement, wiring and attractive in appearance, needs first by stretching for power cable inner core.Traditional span wire system is people's attached cable, and it is stretching that another people uses vice to clamp cable inner core.This mode, due to firmly uneven, easily damages cable and peripheral equipment, and comparatively large by the impact of operational environment, and the cable operated being suspended from eminence is got up more difficult.Therefore traditional span wire system is easily damaged cable, is wasted time and energy, inefficiency, needs to improve.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, there is provided a kind of simple and practical, rapidly and efficiently, the power cable inner core straightening device of safety labor-saving, effectively can avoid damaging cable and peripheral equipment situation, singlely can to fulfil assignment, effectively save human cost.
The technical scheme adopted for realizing the purpose of this utility model is: a kind of power cable inner core straightening device, comprise a L bracket, described support one end arranges wire clamp, the other end arranges fixed pulley, and described support is hinged with single-handle type drawtongs by connecting rod.
Between the handle of described drawtongs and described support, Compress Spring is set.
On described handle and support, correspondence arranges Anti-slip cover.
Described drawtongs arranges elastic anti-slip jaw.
Described stent length is adjustable.
Described connecting rod is arranged adjustment round.
Power cable termination is fixed by adopting wire clamp in L bracket one end by the utility model, the other end carries out tractive by pulley and the single-handle type drawtongs hinged with support to cable core, cable internal core wire to be straightened is got one and is walked around pulley and put into jaw inside, to hold with a firm grip handle and bracing frame, stressed along with handle, cable internal core wire end around binding clip axis of rotation, and then is clamped by jaw by lower side handle; When continuation increase grip holds handle with a firm grip, single-handle type drawtongs is overall around supporting the axis of rotation added, thus drives heart yearn end that internal core wire is stretching by binding clip.By arranging Compress Spring between handle and support, after cable internal core wire is straightened, release handle, under the effect of Compress Spring, handle is softened, and now jaw opens automatically, take off the cable internal core wire be straightened, exchange an other internal core wire for put into jaw and carry out stretching, circulate successively, can be all stretching by the internal core wire of power cable.
The utility model is simple and practical, simple to operate, laborsaving, drastically increases the operating efficiency of stretching cable inner core in cable laying construction, the unnecessary damage caused surrounding devices and cable when avoiding bracing wire.
