Description
Technical field
The invention belongs to loop chain tightener technical field, the arrangement of clutch of a kind of loop chain tightener.
Background technology
Loop chain tightener is by handle drives chain by manpower, with the lifting gear driving load-engaging device to move.Its knot
Structure is compact, easy to carry, easily operates, it is adaptable to outlying district and the lifting in field, drags and draws operation, and promote and drag draw away from
From unrestricted.Particularly in the stringing operation of power industry, usually require that wire stretcher has and drag chain function, at Light Condition
Time can quickly drag chain, improve work efficiency.
In prior art, such as: application number 200710068510.2 China a kind of legerity type aluminum described in utility model closes
Gold loop chain tightener, it drags brake seat in chain mechanism and loads the left side of long shaft gear by spline, and friction plate empty set is being braked
On device seat, brake spring is placed between brake seat and brake nut, and the operation principle of this mechanism is to utilize clutch bullet
The elastic force of spring makes brake get loose when zero load, thus drags chain.The most this mechanism when small load ratchet with
Friction plate skid cause brake may the problem of braking operation, there is potential safety hazard.
Summary of the invention
It is an object of the invention to provide the arrangement of clutch of a kind of loop chain tightener, both can guarantee that safety arrestment works, and had again
Have time and be downloaded from by the function draging chain.
The technical scheme is that: the arrangement of clutch of a kind of loop chain tightener, including major axis
With the brake seat being arranged on described major axis, stop-nut and handwheel, described brake seat is socketed with ratchet, described spine
The wheel both sides of wheel are provided with friction plate, the adjustment wheel also include location wheel, being arranged between stop-nut and handwheel and clutch torsion spring,
Described adjustment is taken turns and major axis synchronous axial system, and described clutch torsion spring is arranged on stop-nut and adjusts between wheel, the termination at its two ends
It is connected to stop-nut and adjusts on wheel；Be socketed on major axis in described handwheel and with described stop-nut synchronous axial system,
Described location wheel and major axis synchronous axial system and rotating around long axis ray relative to handwheel, described handwheel and positioning is provided with location between taking turns
Mechanism, makes handwheel relatively rotate with location wheel holding or be relatively fixed by described detent mechanism.
When load, loop chain tightener of the prior art makes stop-nut pressing friction sheet and spine by rotating handwheel
Wheel, makes ratchet rotate together by frictional force, and it is disadvantageously, when rotating handwheel, brake spring is compressed, the elastic force of generation
Act on stop-nut, make stop-nut be difficult to by friction plate and compress ratchet, and stop-nut is big with the pressure of ratchet
The little size depending entirely on the power that user is applied on handwheel, the tightest by stop-nut and ratchet pressure, braking effect is more
Good, the power on handwheel that acts on is the biggest, and user operation is the hardest.And in use due to vibration and brake spring
Elastic force effect so that stop-nut convolution and cause dynamic nut and the pressure of ratchet to reduce, ratchet easily skids and causes losing
Braking function.The present invention is provided with location wheel, adjusts wheel and clutch torsion spring, when zero load, by hand wheel rotating stop-nut, makes
Brake gets loose, and now detent mechanism runs and handwheel, stop-nut is connected as a single entity, with major axis together with adjustment wheel and location wheel
Rotating, now chain can freely drag.During load, rotational positioning is taken turns so that it is separate with handwheel, makes braking by rotating handwheel
Nut compresses ratchet, and clutch torsion spring is by, on twisting force to stop-nut, making stop-nut automatic impaction ratchet, pass through simultaneously
This dual function makes stop-nut compress ratchet, it is ensured that braking effect.
As preferably, described stop-nut is provided with Access Division with the junction of described handwheel, and described Access Division includes clamping
Arm, forms buckling groove between adjacent two snap-arms, described handwheel is by snap-arms and buckling groove and stop-nut clamping.
As preferably, the described wheel that adjusts is provided with stop part, the end of described clutch one end near one end of clutch torsion spring
Head is fixed on described stop part.
As preferably, described stop part is provided with the side block portion extending to clutch torsion spring and being surrounded by clutch one end.
As preferably, described location wheel is socketed in handwheel, and the described wheel that adjusts is connected to major axis with location wheel by spline
On, and be fixed on major axis by nut.
As preferably, described detent mechanism includes the locating slot being arranged on the wheel of location, the hole, location being arranged on handwheel
With the keeper being arranged in hole, location and elastic component, described keeper moves under the elastic force effect of elastic component in hole, location
Dynamic, make described keeper be pressed on location and take turns above or in locating slot, make handwheel relatively rotate with location wheel holding or be relatively fixed.
As preferably, described handwheel is provided with positioning seat, and hole, described location is arranged on positioning seat.
As preferably, described location wheel is provided with connecting portion, and described connecting portion is connected on major axis by spline, described fixed
Position groove is arranged on connecting portion.
As preferably, in the wheel of described location, it is provided with the rotating part for rotational positioning wheel.
In sum, the present invention has a following beneficial effect: the present invention is simple to operation, good braking effect, safety
Height, duty switching is simple, flexible, only need to apply less power by handwheel and brake can be made normally to work, Er Qieyou
In the effect of clutch torsion spring, both increase the pressure of stop-nut and ratchet, it is ensured that braking effect, prevent again stop-nut pine
De-, improve security performance.
