Abstract
The invention discloses a pulley-type steel wire rope tensioner which comprises a U-shaped base. Fixed pulleys are respectively arranged on two parallel vertical beams of the U-shaped base; a through hole is formed in a cross beam of the U-shaped base; a movable rod penetrates through the through hole; a pair of tensioning wheels is arranged at the end part, inside the U-shaped base, of the movable rod; a jacking block is arranged at the end part, outside the U-shaped base, of the movable rod; and a pressure spring is arranged between the jacking block and the outer surface of the cross beam of the U-shaped base. The pulley-type steel wire rope tensioner provided by the invention is simple in structure and convenient to operate; and by adoption of such a structure that the pressure spring and the fixed pulleys are mutually matched, online regulation can be achieved, and the tedious processes for mounting, dismounting and cutting off a steel wire rope can be omitted.
Description
Technical field
The present invention relates to steel wire rope arts, be specifically related to a kind of pulley type steel wire tensioning dress
Put.
Background technology
Steel wire rope plays the effect bearing load, and its performance is mainly determined by steel wire.Steel wire is carbon
Element steel or steel alloy, by cold drawn or cold rolling circle (or abnormity) silk material, have the highest
Intensity and toughness, and according to use environmental condition difference steel wire is carried out surface process.Conventional
Steel wire rope turnbuckle, also known as flange bolt or screw-button, two ends connecting steel wire ropes can only be passed through,
The degree of tightness of steel wire rope could be regulated, and the scope of regulation is the most limited.It is only applicable to fixed
Steel wire rope regulates, and needs will embed when mounted in steel wire rope, is in-line with circuit,
Can only maintain static, and pulley can not be walked around, it is impossible to tensioning steel wire rope the most at an arbitrary position,
More can not meet the tensioning of closed cycle steel wire rope.Because stretcher must be connected, often to take apart
Bearing or cut off steel wire rope and carry out tensioning, operating difficulties, and in access section, steel wire rope is had damage.
Therefore, it is necessary to the steel wire rope stretching device of prior art is carried out structure improvement.
Summary of the invention
It is an object of the invention to overcome defect present in prior art, it is provided that a kind of online
Tight pulley type steel wire rope stretching device.
For achieving the above object, the technical scheme is that a kind of pulley type steel wire tensioning
Device, it is characterised in that include U-shaped pedestal, two parallel longerons of described U-shaped pedestal are respectively
Being provided with fixed pulley, the crossbeam of described U-shaped pedestal is provided with through hole, motion bar is through described
Through hole, described motion bar is positioned at the end of U-shaped pedestal and is provided with a pair regulating wheel, described work
The end that lever is positioned at outside U-shaped pedestal is provided with top briquetting, described top briquetting and U-shaped pedestal
Stage clip it is provided with between beam outer surface.
Wherein, gap between regulating wheel outline described in two is less than wirerope diameter.
Wherein, described fixed pulley being provided with locating part, the two ends of described locating part are respectively at fixed
The detachable fixing connection in two sides of pulley.
Advantages of the present invention and having the beneficial effects that:
The steel wire rope stretching device simple in construction of the present invention, easy to operate convenience, pressed by employing
The structure that spring matches with fixed pulley, may be implemented in line and is automatically adjusted, it is to avoid handling and stage steel
Cord loaded down with trivial details.
Accompanying drawing explanation
Fig. 1 is the structural representation of pulley type steel wire rope stretching device of the present invention.
In figure: 1, U-shaped pedestal；2, fixed pulley；3, motion bar；4, regulating wheel；5、
Top briquetting；6, stage clip.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, the detailed description of the invention of the present invention is retouched further
State.Following example are only used for clearly illustrating technical scheme, and can not be with
This limits the scope of the invention.
As it is shown in figure 1, embodiment pulley type steel wire rope stretching device, including U-shaped pedestal 1, U
Two parallel longerons of shape pedestal 1 are respectively arranged with fixed pulley 2, and the crossbeam of U-shaped pedestal 1 is arranged
Having through hole, motion bar 3 is through through hole, and motion bar 3 is positioned at the end of U-shaped pedestal 1 and is provided with
A pair regulating wheel 4, the end that motion bar 3 is positioned at outside U-shaped pedestal 1 is provided with top briquetting 5, top pressure
Stage clip 6 it is provided with between the beam outer surface of block 5 and U-shaped pedestal 1.
Wherein, the gap between two regulating wheel 4 outlines is less than wirerope diameter.
Wherein, fixed pulley 2 being provided with locating part 5, the two ends of locating part 5 are respectively at fixed pulley 2
The detachable fixing connection in two sides.
When installing steel wire rope, directly this steel wire rope stretching device is serially connected with on steel wire rope, profit
With the elastic force of stage clip, automatically control steel wire tensioning degree.
The above is only the preferred embodiment of the present invention, it is noted that lead for this technology
For the those of ordinary skill in territory, on the premise of without departing from the technology of the present invention principle, it is also possible to
Making some improvements and modifications, these improvements and modifications also should be regarded as protection scope of the present invention.
