Description
Technical field
The present invention relates to a kind of tension release device, more particularly to a kind of device for releasing tension of steel cable.
Background technology
In the equipment carrying out traction using steel wire rope, often traction is carried out using the steel wire rope of more than two.Due to draging
The change of steel wire rope tension and elongation during drawing, produce the direction that fag end can be loosened by turning moment to moment of torsion in steel wire rope
Rotation, a portion in therefore coefficient many steel wire ropes is likely to occur abnormal elongation, thus leading to steel wire rope to be opened
Power disequilibrium.If this state development of leaving down, remaining steel wire rope will produce excessive tension force, thus leading to steel
Too early fracture of wire or stranded phenomenon in the steel wire of cord, brings larger potential safety hazard.It is thus desirable to producing to steel wire rope
Raw tension force is discharged.From the point of view of by the way of current the employing, in the steel wire rope head assemblies of great majority uses and without steel
The device of cord release of tension, the release of steel wire rope tension be manually periodically by the fag end lock screw of steel wire rope back-out by
Bar discharges tension force, so can neither solve the impact of steel wire tension in time, waste time and energy again.At present with regard to steel wire rope torsion release
Device, its common feature is：Solve only the problem that steel wire rope torsion can freely discharge, but all not to steel wire rope tension
The time of release is effectively controlled, and discharges at any time.And the release of excessively free steel wire rope tension also bring along unfavorable
Impact：(1) with the operation up and down of the equipment of steel wire rope institute traction, steel wire rope tension can periodically produce, and steel wire rope also can
Periodically constantly reverse to tighten up and loosen with torsion, so can make the easy defatigation of steel wire rope of fag end part, service life reduction；
(2) when the running stability of the equipment to the traction of steel wire rope institute has higher requirements, such as have during the car of towed elevator equipment
The requirement of higher vibration performance index, constantly reverses due to when steel wire rope tension discharges, and is likely to result in steel wire rope and connects with rope sheave
The friction of contacting surface, so can produce vibration and then affect the comfort taken, also can cause unnecessary abrasion to rope sheave race,
And then reduce the service life of rope sheave.
Content of the invention

The design of spring adjusting nut, can be easy to adjust the size of amount of spring compression, control the adjustment pressure to release of tension axle sleeve for the screw rod
Size, and then control the size of tension force during steel wire rope tension release.The design of rule is big corresponding to amount of spring compression
Little, it is conveniently adjusted the design load for regulation.
The vertical plate of each device for releasing tension of steel cable is sequentially connected in series by perforate on described vertical plate with a hawser
Together, tighten up and buckled with lock after hawser, so can prevent from mutually involving between vertical plate with each, prevent due to spring with
Not, vertical plate can rotate frictional force between horizontal plate with pull bar.
Described release of tension axle sleeve fixation is set on pull bar, and its bottom is connected on the inner ring of described rolling bearing.This
Sample design is it is ensured that release of tension axle sleeve and pull bar, the inner ring of rolling bearing are with freely horizontally rotating together with steel wire rope.
The invention has the beneficial effects as follows：Structure is simple, reasonable in design, using the profile of tooth of adjusting screw rod and release of tension axle sleeve
Engagement is it is achieved that to the Spin Control in steel wire rope horizontal direction；Using adjust compression spring decrement by the way of it is achieved that
Control to the size of steel wire rope tensioning release force, and then control the temporal frequency of steel wire rope tension release.
