Abstract
The invention discloses an existing cable force fine adjusting device. The existing cable force fine adjusting device comprises a mechanical frame, pulleys arranged on two ends of the mechanical frame and a micro jack which is arranged in the middle part of the mechanical frame, wherein the mechanical frame is of a bow-shaped structure; and a passage used for a pulling cable to penetrate through is formed between the positions for arranging the pulleys at the two ends and the inner side of the bow-shaped structure. Great pushing force can be provided by the existing cable force fine adjusting device, so that adjusting on large pulling cable structures is realized; adjusting difficulty is lowered; and operation is convenient.
Description
Technical field
The present invention relates to a kind of rope apparatus for adjusting force, specifically, it is to be related to a kind of existing Suo Li fine setting for drag-line
Device.
Background technology
Now in many engineerings, all there is the part of stayed structure.During actual installation, drag-line often needs
Carry out being connected with each other operation, be mostly in current engineering by the way of the regulation connecting screw rod at manually drag-line two ends
To realize the regulation to Suo Li.But, the drag-line in large scale structure has larger Suo Li, and the method adopting at present is in this feelings
Operate under condition extremely difficult.
Accordingly, it would be desirable to a kind of existing Suo Li micromatic setting.
Content of the invention
Technical problem：It is big that the present invention is to provide for a kind of strength of adjustment, easy and simple to handle, reduce the existing of difficulty of construction
Suo Li micromatic setting, the Suo Li that can reach drag-line by way of Minitype jack adjusts requirement, solves current regulation drag-line
Difficult problem.
Technical scheme：A kind of existing Suo Li micromatic setting of the present invention, including mechanical framework, is arranged on described mechanical framework
The pulley at two ends and the Minitype jack being arranged in the middle part of mechanical framework, described mechanical framework is bow antiform, in two ends peace
It is provided with order to the passage through drag-line between inside the position of dress pulley and bow antiform.
Further, in apparatus of the present invention, the bow antiform of mechanical framework includes cross bar and is located at described cross bar two ends
Two armed levers, the subtended angle between described armed lever and cross bar be obtuse angle.
Further, in apparatus of the present invention, pulley is fixedly mounted on the pulley draw-in groove at mechanical framework two ends by pin.
Further, in apparatus of the present invention, Minitype jack is fixed on the inner side midpoint of mechanical rod member back of a bow shape construction.
In the present invention, when Minitype jack is along during perpendicular to drag-line direction applying external force, under the constraint of both sides armed lever, make
Obtain drag-line and produce lateral displacement, drag-line inner cable power changes.Minitype jack can provide very big motive force, thus real
Show the regulation to large-scale stayed structure, reduce operation easier.
Minitype jack is fixed on mechanical rod member cross bar midpoint, is located at homonymy with armed lever.During work, Minitype jack to
Outer promotion drag-line, the pulley draw-in groove of both sides constrains the two ends of drag-line, thus Suo Li changes in drag-line.
Beneficial effect：The present invention compared with prior art, has advantages below：
1. the design that the present invention adopts, by with Minitype jack, it is provided that very big motive force, strength of adjustment is big
The power that will be perpendicular to drag-line direction is converted into along drag-line direction, reduces and adjusts, to drag-line, the operation that particularly large-tonnage drag-line is adjusted
Difficulty；
2. the present invention adopts integral structure, installs and adjusts process simply, facilitate the operation in each engineering in practice
Librarian use；
3. the material that the present invention adopts and structural design scheme are very easy realization, less demanding to production technology, and
Manufacturing cost is relatively low, and suitable large-scale promotion is used.
Brief description
Fig. 1 is the structural representation of the present invention.
Wherein, 1 mechanical framework, 2 pulleys, 3 drag-lines, 4 Minitype jacks.
Specific embodiment
Below in conjunction with the accompanying drawings and give an actual example, Suo Li micromatic setting existing to the present invention is described in detail.
A kind of existing Suo Li micromatic setting of the present invention, including mechanical framework 1 and Minitype jack 4.When Minitype jack 4
Along when applying external force perpendicular to drag-line direction, under the constraint of mechanical framework 1 both sides armed lever, drag-line 3 produces lateral displacement, its
Inner cable power will change.Minitype jack 4 can provide very big motive force, it is achieved thereby that to large-scale stayed structure
Regulation, reduce regulation difficulty.
Mechanical framework 1 is made up of a mechanical rod member and two pulley draw-in grooves 2.Mechanical rod member main body is three trapezoidal shapes
State arrangement mechanical shaft, comprises two armed levers and a cross bar, armed lever is connected on cross bar, and between adjacent machine bar, subtended angle is blunt
Angle.Pulley draw-in groove 2 is located at the outer end of two armed levers respectively, is fixed by pin, by drag-line 3 from pulley draw-in groove 2 and machinery during work
Space between the mechanical arm of framework 1 passes through and fixes.
Minitype jack 4 is fixed on mechanical rod member 1 cross bar midpoint, is located at homonymy with armed lever.During work, Minitype jack
4 push out drag-line 1, and the pulley draw-in groove 2 of both sides constrains the two ends of drag-line 3, so that Suo Li changes along along drag-line 2.
Above-described embodiment be only the preferred embodiment of the present invention it should be pointed out that：For those skilled in the art
For, under the premise without departing from the principles of the invention, some improvement and equivalent can also be made, these are to right of the present invention
Require to improve and the technical scheme after equivalent, each fall within protection scope of the present invention.
