Apparatus for adjusting force includes fixed cover, spring and guide rod, and the fixed cover is arranged on the top of support straight down, and spring is arranged at
In fixed cover, the guide rod is goed deep into being fixedly connected in fixed cover and with spring, and the other end of guide rod rotates connection pulley.
But so tensile force is determined by the stroke itself of gravity and spring, and fixed cover is fixed on branch in itself
Top of the trellis, it is also difficult to adjust；So that uncontrollable tensile force, so that tensile force is difficult to properly.
Utility model content
The purpose of this utility model is to provide a kind of spoke wire tensioning apparatus of control tensile force.
Above-mentioned technical purpose of the present utility model technical scheme is that：
A kind of spoke wire tensioning apparatus, including fixed cover, fixed cover sliding are connected with the nutted rod of vertical lifting, tensioning
Bar upper end is rotatably connected to the tensioning wheel for abutting steel wire, and fixed cover slides the adjustment for being connected with vertical lifting below nutted rod
Plate, and fixed cover is connected with the fixture of fixed adjustment plate, being provided between adjustment plate and nutted rod makes nutted rod all the time with slotting
Enter the trend of fixed cover, adjacent surface of the both ends of the spring respectively with both adjustment plate, nutted rod is affixed.
By using such scheme, unclamp fixture, adjustment plate is slid up and down, thus change adjustment plate and nutted rod it
Between spacing, that is, the stroke needed for changing spring according to Hooke's law, also just changes the pulling force of spring offer, and is tensioned
Power is made up of the gravity of nutted rod itself and pulling force two parts of spring, so have adjusted tensile force, tensile force was both opened
Tight steel wire, and the smooth transmission of steel wire is not influenceed.
Preferably, fixture is bolt, fixed cover side face is provided with the word hole for bolt sliding, bolt-through one vertically
Word hole and with adjustment plate bolt connection, fixed cover wall is held between bolt and adjustment plate.
It is convenient and swift using the pretightning force fixed adjustment plate for tightening bolt generation by using such scheme, it is easy to solid
It is fixed.

Gap.
By using such scheme, tensioning wheel is installed using mounting bracket, tensioning wheel is rotated with nutted rod and be connected, while will
Steel wire is limited in mounting bracket, even if because unexpected steel wire departs from from tensioning wheel, rotating shaft can also keep the tensioning to steel wire.
Preferably, tensioning wheel side face both sides have radially extended flange.
Wire clip is handled by using such scheme, flange, it is ensured that steel wire be located at tensioning wheel side face on, prevent steel wire from
Depart from tensioning wheel.
Preferably, both ends of the spring extends and is bent into crotch, adjustment plate is connected with confession with the adjacent surface of both nutted rods
The retainer ring of crotch mounting.
After long-time use, spring may fatigue failure, hang over this connected mode in retainer ring using by crotch,
It is easy to change spring.
Preferably, adjustment plate is detachably fixed the position-limiting cover for being connected with and being set in fixed cover, position-limiting cover top surface is provided with confession
The through hole that spring runs through, when spring in the raw under, nutted rod is abutted with position-limiting cover top surface.
By using such scheme, position-limiting cover support does not provide the nutted rod of tensioning when shutting down, prevent nutted rod from extruding bullet
Spring, is also prevented from departing from extrusion process hook and retainer ring；The state of fixed cylinder inner spring is also can determine that simultaneously, when spring starts
When tired, now even under nature, nutted rod cannot also be abutted spring with position-limiting cover top surface, so as to judge fixed cylinder
The state of inner spring, changes spring in time, it is ensured that the tensioning to steel wire.
Preferably, position-limiting cover includes into the connecting portion of hollow cylindrical and the top board of closing connecting portion one end, through hole position
In ceiling center, and connecting portion and adjustment plate mode connects for screw.
By using such scheme, using threaded connection, simple structure, connection is reliable, be convenient to mount and dismount, and is easily installed and tears open
Unload；During installation, first spring one end is hung in adjustment plate, then be twisted position-limiting cover, finally spring is pulled out and hung over from through hole
On nutted rod, the fixation of spring is completed.
Preferably, top board is coated with rubber ring away from connecting portion one end.
Impulsive force during nutted rod resilience is absorbed, prevents nutted rod from being hit with position-limiting cover by using such scheme, rubber ring
Damage.
In sum, the utility model has the advantages that：Change the position of adjustment plate using bolt and a word hole,
So as to change the required cord retraction amount of spring, so as to have adjusted tensile force, tensile force is set both to be tensioned steel wire, and do not influence
The smooth transmission of steel wire；And position-limiting cover carries the nutted rod for not providing tensile force, it is ensured that the spring for hanging is completely embedded.
