Description
Technical field
The present invention relates to a kind of preamble according to claim 1, for elevator speed limit steel wire rope tensioning dress
Put.
Background technology
Elevator is typically provided with traditional speed limit steel wire rope at least insofar.
Here is continuous steel wire rope, and which is at least through upper and lower directive wheel cycle operation.According to typical way, speed limit steel wire
Rope is fixed on for triggering stopping and brake unit, armed lever in cage side for car.It is by this way and square
Method, speed limit steel wire rope are carried and are thus driven by car.
According to typical way, upper directive wheel is connected with the limiter of speed of script.If the directive wheel rotates too fast, then it represents that sedan-chair
Railway carriage or compartment has exceeded maximum permission speed and has been braked or or even must stop.Thus limiter of speed will enter to the directive wheel for belonging to which
Row slows down.Speed limit steel wire rope becomes slow, lags behind elevator, by this way with method triggering generally such as front mechanical braking
And pause equipment.
For normal function, it is necessary to correct tensioning speed limit steel wire rope.Because the directive wheel of limiter of speed can belonged to otherwise
Occur and speed limit steel wire rope between lax.Speed limit steel wire rope cannot be slowed down by regulation by the directive wheel corresponding to the limiter of speed, enter
And its function cannot be met.
Based on possible in sometimes very long speed limit steel wire rope (if building has the floor of respective numbers) and elevator
The different temperatures of appearance, it is necessary to such tensioning speed limit steel wire rope, i.e. facilitate the tensioner of tensioning at any time can be in order to avoid pine
Relax and readjust tensioning, or can loosen to prevent speed limit steel wire rope overload.
Prior art
Thus counterweight is used mostly at present as tensioner, their lower directive wheel loadings to speed limit steel wire rope, thus
Using constant gravity and and then constant tension force tensioning speed limit steel wire rope, no matter speed limit steel wire rope elongated at present it is how many or
Retract how many.
But the tensioner of this weight loading tends to vibrate once in a while, this is undesirable.Additionally, themselves is
Complicated, this is that, due to needing respective quality to be tensioned, and quality simply arbitrarily cannot hang, but needs also exist for drawing
Lead.
Therefore, it is more and more using spring-loaded tensioner.The existing tensioner worked using spring tension, just
For its pretightning force, it is impossible to sufficiently exact guiding is provided and/or sensitive cannot be adjusted.
The content of the invention
In view of this, task of the present invention is to provide a kind of tensioner, and which is capable of achieving accurately and securely guides directive wheel,
And which constructs especially narrowly, so as to be directed to predetermined stair shaft cross section, as far as possible big car bottom surface is realized.
The solution is reached using the feature of claim 1.
For term "up" and "down" used below, which is related to tensioner of the normal mounting in lift facility.
Accordingly advise a kind of tensioner of the speed limit steel wire rope for elevator, the tensioner has for being pretension
Speed limit steel wire rope and tense the spring tensioning mechanism of directive wheel, the directive wheel keeps the steel wire rope.Here, the tensioned
Mechanism includes at least two guide pillars.The two guide pillars are arranged side by side on the same side of directive wheel.At least one spring element point
It is not through on each guide pillar.Main frame so keeps guide pillar, i.e. its first guide pillar part is fully located at (to be sealed comprehensively by main frame
Close or at least substantially close in four side seals) in the region that surrounds.In contrast, the second guide pillar part of guide pillar above main frame and
Outside the region surrounded positioned at main frame.Tensioner also includes balladeur train.Carriage supports are installed in rotation on guiding thereon
Wheel.Balladeur train is bearing on guide pillar according to slidably mode using two yokes or yoke plate.Here, transporting on the first guide pillar part
The lower yoke of dynamic balladeur train constitutes the bearing of spring element, and spring element is supported on the upper horizontal component of main frame in its opposite side
On.The pressure of spring element acts on the lower yoke of balladeur train and which is drop-down.The upper yoke of balladeur train is on the second guide pillar part
Move and preferably backstop is on adjustable spring travel limitor.
Realize unnecessary tensioner by this way with method, if spring element is out of order (if for example using spiral shell
Spinning spring and occur spring coil fracture on helical compression spring), then tensioner also will not failure completely.
Additionally, the particular embodiment of guide pillar allows very stably guide carriage.Because the guide carriage on guide pillar
Yoke part is separated from each other very remote up and down.Thus they particularly good support carriages and keep guiding thereon
Wheel, resists the vertically acting power in them.As a result, directive wheel is although its floating support also will not be due to undesirable with regard to water
Flat axis is pivoted and run-off the straight.And directive wheel around vertical axis pivot also by being arranged side by side in directive wheel side
Two guide pillars are effectively contained.Based on all these measures, extremely narrow, its Breadth Maximum of tensioner construction of the present invention
The diameter or width of spring element is roughly equivalent to along with the width of the protecting cover of the width or protection directive wheel of directive wheel.Change and
Yan Zhi：The width of tensioner generally not over " guide rail stretches into the innermost end of stair shaft in the horizontal direction " and " keeps
Spacing between the borehole wall of guide rail ".If the elevator of available stair shaft cross section thus should be made full use of (mostly constitution optimization
Number is machine room), it is also possible to use tensioner of the present invention with having no problem.
Specify in a preferred refinement of the present invention, main frame is complete Self-Closing four sides.With
This ways and means quite importantly obtain being beneficial to general main frame, and its own is stable, if which does not utilize
Its foot's twist-on is on stair shaft bottom, but is fixed at least one of which guide rail using the help for keeping camber member.
Guided carriage is preferably made up of C-shaped camber member, and the C-shaped camber member has preferably straight mid portion and two
It is preferred that protruding from its short supporting leg at a right angle.Here, each short supporting leg transits to yoke.This guided carriage can be very simple
It is single and firmly manufacture very much, by one or more respective curveds and the band steel of twist-on or welding is made each other.In order to provide
For the bearing of floating support directive wheel, it is advantageous to by bearing bolt weld or twist-on C-shaped camber member mid portion
On, directive wheel is rotatably disposed on C-shaped camber member.
The preferred integral type of upper supporting leg transits to the yoke for belonging to upper supporting leg.This simplifies manufacture.Yoke and C-shaped camber member can
With by a part punching press, then bending forming.
It is proved advantageously, yoke move on guide pillar using eye is oriented to, these are oriented to eyes respectively with being directed away from
The breach that the side of directive wheel is opened wide.This simplifies assembling.So, upper yoke need not be through thereon from guide rod end.But
Particularly simple upper yoke can be pushed away from side and be attached on guide rod, i.e. from the side towards " directive wheel in operation will not
Deflect or swing due to acting on its rope force and tension force " side.
The preferred floating support of directive wheel is on the preferred straight mid portion of C-shaped camber member.Floating support here is helped
In：The width of tensioner is down to into minimum in the operation pivot center direction of directive wheel.
Especially suitable, these guide pillars are only completely fixed on the lower horizontal component of main frame, and these guide pillars are only passed through
Wear the upper horizontal component of main frame, i.e. pass through via upper horizontal component.This is when necessary, hence it is evident that simplify spring element more
Change.Each guide pillar only need to be unclamped from the lower horizontal component of main frame, and completely or at least partially can be pulled out upwards.
Have been found to particularly advantageously, the upper horizontal component of main frame has recess or a depression, C-shaped camber member it is straight
Mid portion is inserted into the inner.Thus C-shaped camber member and main frame can also more closely against each other, such that it is able to realize into one
