The dependable performance when structure design of this catching device may make catching device to realize anti-fall locking simultaneously.
A kind of catching device of anti-fall dependable performance provided by the invention is solved the problems, such as by following technical essential：One kind is anti-
The catching device of dependable performance, including rack are fallen, the runner in rack is installed on by first rotating shaft, the runner can be around first turn
The axis of axis rotates, and multiple journal stirrups are provided in the outer rim of runner, and the journal stirrup is annularly evenly distributed with distribution relation between each other, also
Include for realizing the constriction of runner locking, the constriction includes flipping block, scotch and triggering block, the scotch with
Triggering block is both secured on flipping block；
Further include the 4th shaft, the scotch is rotationally connected with by the 4th shaft on flipping block, and under scaffold
It falls in driving runner rotation process, for scotch when by the thrust applied by catching device upper journal, scotch can be around described the
Four shafts rotate；
Further include the second shaft, the flipping block is connected by the second shaft with rack, and flipping block can be around the second shaft
Axis rotates, and cooperation position of second shaft on flipping block is between scotch and triggering block；
Under constriction and runner disengaged position, flipping block torque caused by both scotch and triggering block gravity is made
Under, using the second shaft as shaft, to following replying state：Triggering block is located in the movement locus of journal stirrup, and scotch is located at branch
Other than the movement locus of ear；
In scaffold falls driving runner rotation process, when triggering block is constrained by arbitrary journal stirrup, triggering block is right
Answer drives flipping block to be rotated around the second shaft under the active force of journal stirrup, and scotch turns to the movement locus of journal stirrup with flipping block
It is interior；
Further include the support portion being set in rack, the support zone is propped up in the side of scotch in scotch
When the thrust of ear, scotch makes scotch part be subjected to displacement in the circumferential direction of runner by rotation, the support zone
In on the deformation trace, the support portion is used to limit the position of the displacement stop；
The first rotating shaft, the second shaft, the 4th shaft three axis be mutually parallel；
Further include the limited block being set on flipping block, the limited block is for being limited to movement rail of the scotch to journal stirrup
In mark when movement, dead-centre position that scotch rotates around the 4th shaft.
Specifically, this programme is when in use, since catching device and guide rail have relatively on the length direction along guide rail
Movement, in the above relative movement, when guide rail cross tube interacts with the journal stirrup on runner, cross bar drives runner
It is rotated by shaft of first rotating shaft, i.e. elevating scaffold decrease speed is faster, and runner rotates faster around first rotating shaft.
In the present solution, using the second shaft as rotation center, scotch is equivalent to triggering block as institute flipping block on constriction
State the clump weight in not homonymy on rotation center a pair of opposite side, constraints above portion be runner under runner disengaged position with
Constriction is contactless, and flipping block is only in the state of the torque that both sides clump weight gravity generates.In this way, when runner is rotating
In the process, when arbitrary journal stirrup streaks triggering block position, corresponding journal stirrup promotes flipping block with the second shaft triggering block application
For center of rotation, the power of scotch side to overturn to where entering runner rotary motion trace；It is closed in the constraint of corresponding journal stirrup and triggering block
After system removes, flipping block is rotated around the second shaft to restore state under the action of the clump weight of both sides.And streaked due to journal stirrup
Track is fixed, in this way, when each journal stirrup is acted on triggering block successively, position of the fulcrum that each triggering block can be moved to scotch
Relatively fixed, the turnaround time of flipping block is relatively fixed, in this way, when next journal stirrup turns at scotch position, stop
Whether block determines can scotch realize locking to runner via deviating from the movement locus of journal stirrup, and next journal stirrup
Whether scotch is determined by deviating from the movement locus of journal stirrup by the velocity of rotation of runner when turning to scotch position, above turn
The velocity of rotation of wheel determines by the decrease speed of guide rail, in this way, when the rotating speed of runner exceeds certain rotating speed, since scotch comes
It has an effect with journal stirrup not as good as by deviating from the movement locus of journal stirrup, in this way, being used for by the radial direction setting in runner
Scotch to be in contact condition with journal stirrup provides the support portion of support, or is directly transmitted and used by flipping block, the second shaft
In the power of locking runner, you can, can by the journal stirrup on runner after realizing that the locking rotated to runner, the above runner are locked
The locking to guide rail cross tube is realized, to reach anti-fall purpose.
In the present solution, by being limited in rack include support portion, while scotch is turned by the 4th shaft and flipping block
Dynamic connection, in this way, scotch, when by the thrust applied by catching device upper journal, scotch can occur to turn under the thrust
Dynamic or sliding, due to defined above parallel for first rotating shaft, the second shaft, the 4th shaft three's axis, scotch is with flipping block
It is rotated around the second shaft under the action of triggering block, when scotch is entered the rotary motion trace of journal stirrup by the outside of runner, scotch
It rotates under the action of corresponding journal stirrup, since the direction of motion of corresponding journal stirrup is the circumferential direction along runner, in this way, right
Answer journal stirrup that scotch part is driven to be rotated to the direction of motion along corresponding journal stirrup by shaft of the 4th shaft, in this way, scotch
It is subjected to displacement in the circumferential direction of runner.By the way that support portion is arranged in the rack of catching device, portion supported above is scotch
Effect of contraction has been subjected to displacement in the circumferential direction of runner, i.e. support portion is used to provide the supporting surface of support scotch, in this way,
It can be achieved to transmit the power for locking runner directly between runner and rack by scotch, and flipping block itself, constriction and machine
The mechanical property of shaft between frame is only it is required that flipping block is in corresponding catching device work so that flipping block can be repeatedly past
Physical pendulum is dynamic, in this way, the connection relation by being designed as specific scotch and flipping block, can directly be existed by scotch
Power is transmitted between runner and rack, to achieve the purpose that the corresponding catching device stress of optimization, improve corresponding catching device reliability.
As those skilled in the art, the circumferential direction for being actually directed to scotch in runner is moved to occur with support portion
Interaction, actually scotch can be slided along flipping block can also realize foregoing invention purpose, but use above 4th shaft
The scheme that scotch is connected with flipping block is realized, not only so that constriction structure is more simple；Simultaneously as scotch meeting itself
Rotated around the second shaft with flipping block, and when each secondary scotch is constrained by corresponding journal stirrup position of the journal stirrup in space and
State may be different, if being set as the above relationship that is slidably connected, in this way, can not make on scotch for making with support portion
On face and support portion for scotch thought of as face can not be bonded completely, be unfavorable for support portion in this way to stop
The stability of block support, using this programme, since scotch can be rotated around the 4th shaft, flipping block can be rotated around the second shaft,
In this way, it is ensured that meaning journal stirrup in office is under the restrained condition of scotch, when scotch stress, passes through flipping block rotation, scotch
Rotation obtains support portion to the most reliable holding state of scotch.
The side for being used to contact with journal stirrup as those skilled in the art, such as scotch is leading portion, in the rear end of scotch
Support portion is set, but needs to consider that support portion cannot directly interact with journal stirrup, specifically when setting, may be configured as
Support zone is in having gap for crossing support portion, the setting direction or form of scotch full on the side of journal stirrup or journal stirrup
For sufficient scotch when being contacted with journal stirrup, scotch is as the force transmission member between journal stirrup and support portion.
Meanwhile this catching device is simple in structure, scaffold maximum speed of falling is controllable；Meanwhile compared to the prior art, such as Shen
Please number be：The scheme that the utility application of CN201020668449.2 is provided directly uses on existing runner originally
Body is used for the journal stirrup with cross bar phase separation as the component with constriction phase separation, in this way, can simplify the structure of catching device itself
Design simultaneously as the structures such as anti-fall card wheel need not be designed, therefore may make runner being capable of global formation or realization runner locking
Power transfer route upper connector or joint face it is less, in this way be conducive to catching device mechanical property reliability；Meanwhile compared to
The prior art, installation of the constriction in rack is using the outside for being installed on runner radial direction, in this way, convenient to first
The both ends of shaft are constrained by rack, to promote the bending resistance of first rotating shaft.
Simultaneously as under the action of triggering block, scotch is moved with flipping block to the side for entering journal stirrup pivot region
When, scotch under inertia it is possible that movement of the free end dyskinesia at the 4th rotating shaft position in space, in this way,
The problem of may causing scotch that cannot well enter journal stirrup movement locus, in the present solution, by the way that the limited block is arranged, it is above
Limited block is overturn during entering journal stirrup movement locus with flipping block for constraining scotch, but constraint scotch is not propping up
It is overturn around first rotating shaft under ear effect, in this way, can further improve the reliability of this catching device.
Further technical solution is：
As a kind of concrete implementation form, the scotch, flipping block are in tabular, in scotch to the fortune of journal stirrup
In dynamic rail mark when movement, the dead-centre position that scotch rotates around the 4th shaft is：Scotch turns to mutual with flipping block
The location of when vertical.Using this programme, it may make scotch that can enter branch in flipping block switching process as far as possible
In the movement locus of ear, by support portion, to realize the locking that rack rotates runner.
At work due to this programme, support portion provides supporting surface, described as the specific implementation of support portion
Support portion is arranged in the top of first rotating shaft, and the support portion is to be arranged in rack and triangle that open end is big end lacks
Mouthful, the supporting surface that support portion is used to constrain scotch is an inclined-plane on vee, and along runner under scaffold
Rotation direction when being rotated during drop, one end that inclined-plane is in front end are bottom end, and one end that inclined-plane is in rear end is top.It adopts
With this programme, scotch is entered by the open end of vee in notch, while by oblique where the restriction supporting surface
Face, not only support portion handling ease, while can realize reliable constraint of the support portion to scotch, while inclined-plane is to the fortune of scotch
It is dynamic that there is guiding role, it can be used for avoiding scotch to fail with the restriction relation of support portion under the active force of journal stirrup.
Further include third shaft, the triggering block is connected by third shaft with flipping block, and triggering block can be turned with third
Axis rotates for shaft；
Further include block, when the block is rotated for limiting triggering block around third shaft, rotates the position of stop, it is described
Rotating stop is：Block is that triggering block or third shaft apply constraint and triggering block avoided further to rotate, what triggering block was stopped
Point；
In scaffold falls driving runner rotation process, when triggering block is constrained by arbitrary journal stirrup, triggering block is right
Answer under the active force of journal stirrup with block phase separation, and by block transmit power to drive flipping block to be rotated around the second shaft, stop
Block is turned to flipping block in the movement locus of journal stirrup, at this point, due to transmitting power by block between triggering block and flipping block,
So when triggering block under the action of journal stirrup, force flipping block to rotate, so that scotch is fallen into the rotary motion trace of journal stirrup；
In scaffold rises driving runner rotation process, when triggering block is constrained by arbitrary journal stirrup, triggering block is right
It answers and is rotated around third shaft under the active force of journal stirrup, so that corresponding journal stirrup is mutually staggered with triggering block, at this point, due to triggering block
Realize being staggered for triggering block and journal stirrup relative position by being rotated around third shaft, so when triggering block not by block to turning over
Being transmitted on switch block forces flipping block to rotate, so that the power of scotch and journal stirrup phase separation.
This programme is preferably arranged to third shaft, the 4th shaft, first rotating shaft, the second shaft axis when using
It is parallel.The lock that the transitive dependency of power rotates triggering block around third shaft in block between triggering block and flipping block in above procedure
It is fixed.Since triggering block needs to rotate by shaft of third shaft at work, and in the prior art, triggering block and flipping block are realized
Third shaft itself is not around itself axis when triggering block rotation can be used in the specific implementation being rotatably connected by third shaft
Line rotates：If one end of third shaft is welded to connect with flipping block, be provided in triggering block for third shaft clearance fit
Hole；Also it may be configured as：Third shaft itself is around own axis when triggering block is rotated using third shaft as axis：Such as third
One end of shaft is fixedly connected with triggering block or triggering block is an integral structure with third shaft, be provided on flipping block for
The hole of third shaft clearance fit.So, block is when specific implementation is to triggering block rotational restraint, if third shaft and triggering block
It rotates simultaneously, then may be configured as block and be fixed in rack, the block immediate constraint triggering when third shaft goes to setting position
Block or third shaft, can be by turning when using the realization method of constraint third shaft as those skilled in the art in third
Blocking portion is arranged in the side of third shaft in the blocking portion of end face setting with the block phase separation of axis, and the above blocking portion can be phase
For the end face or side convex block outstanding, i.e. block realizes triggering block rotation lock timing, convex block contacted with block avoid it is convex
Block further rotates；Third shaft itself does not constrain third shaft in triggering block rotation process around the block of own axis
Way of realization directly hindered by block triggering block further around third shaft rotate.
As those skilled in the art, for above scheme when realizing, actually triggering block cannot be around under the action of block
Third shaft does 360 ° of rotations, and this programme needs to meet after completing the assembly with catching device：Runner declines in scaffold
When rotating in the process, journal stirrup can trigger triggering block and directly or indirectly be constrained by block；Runner is in scaffold uphill process transfer
When dynamic, during the entire process of journal stirrup and triggering block phase separation, triggering block is not constrained by block directly or indirectly.
The triggering block set above is connected by third shaft with flipping block, while by designing block so that this programme
Under the premise of meeting scaffold decline lock function, constriction does not influence the maximum speed of runner rotation during being carried on scaffold
Degree, therefore use the catching device of this programme that scaffold will not be caused above to carry when scaffold arbitrary speed is promoted and locked by catching device
Only, it is conducive to improve efficiency when hoisting scaffold, simultaneously because scaffold, when above being carried, each journal stirrup is acted on triggering block successively
When, only triggering block is rotated around third shaft on constriction, therefore compared to flipping block theres is a situation where overturn under journal stirrup effect,
Scheme may make brings the resistance smaller that scaffold is above put forward by catching device.
Specific installation as constriction and setting form, are set as：Second shaft is located at journal stirrup rotary motion trace
Top, flipping block is in a strip shape, and scotch is located at the different ends of flipping block from triggering block.Using this programme, overturning is utilized as far as possible
The length of block come serve as gravity generate torque the arm of force.
For convenience of constriction is changed in a free state, i.e., without under runner restrained condition, scotch is by journal stirrup movement locus
The time of interior abjection is set as with controlling the triggering speed that this catching device realizes the rotation of runner locking runner：Scotch and triggering
In block the two, the connection relation of at least one and flipping block is to be detachably connected relationship.It can be removable with flipping block in this way, adjusting
Unload the quality of the clump weight of connection, you can realize above-mentioned purpose.
For convenience of constriction is changed in a free state, i.e., without under runner restrained condition, scotch is by journal stirrup movement locus
The time of interior abjection is set as with controlling the triggering speed that this catching device realizes the rotation of runner locking runner：Second shaft
Link position on flipping block is adjustable on the length direction of flipping block, and the length direction is scotch and triggering block
Line direction.Using this programme, i.e., by adjusting the means of torque arm length, realize above-mentioned purpose.
As the specific implementation for adjusting torque arm length, multiple hinge holes are provided on the flipping block, it is multiple hinged
Hole is arranged along the length direction, and the second shaft is fixedly connected with rack, and flipping block passes through arbitrary hinge hole and the second shaft
It is connected.
To avoid because flipping block position change on the second shaft axis influences journal stirrup triggering and touches block or influence stop
Block causes the anti-fall performance of this programme unreliable with journal stirrup interaction, is set as：Further include limiting device, the limiting device
For limiting position of the flipping block on the second shaft axis；External screw thread, the limiting device are provided in second shaft
To be threadedly connected to two nuts in the second shaft.This limit device structure is simple, easy to manufacture.
As the specific implementation of runner, the runner includes shell portion and header portion, and the shell portion is in
Tubular, the header portion quantity are two pieces, and respectively end is respectively and fixedly provided with one piece of header portion to shell portion, and header portion is in flat
Plate；
N number of ear block is both provided in each header portion, and the journal stirrup in each header portion is annularly uniformly distributed between each other；
Journal stirrup in the plate part of both ends and is formed along the axis direction face one by one of runner in two ear blocks of face relationship
One journal stirrup；
Each header portion is bolted with shell portion.Using this programme, each journal stirrup overlay area may make not only may be used
It is wider, meanwhile, runner material is few, light-weight.Be bolted above scheme provide it is a kind of connection be easily achieved, simultaneously can avoid
Such as introduce welding heat affected material mechanical performance, so that each component part it is detachable with maintain easily and replace, reduce safeguard or
The technical solution of use cost.
The invention has the advantages that：
In the present solution, by being limited in rack include support portion, while scotch is turned by the 4th shaft and flipping block
Dynamic connection, in this way, scotch, when by the thrust applied by catching device upper journal, scotch can occur to turn under the thrust
Dynamic or sliding, due to defined above parallel for first rotating shaft, the second shaft, the 4th shaft three's axis, scotch is with flipping block
It is rotated around the second shaft under the action of triggering block, when scotch is entered the rotary motion trace of journal stirrup by the outside of runner, scotch
It rotates under the action of corresponding journal stirrup, since the direction of motion of corresponding journal stirrup is the circumferential direction along runner, in this way, right
Answer journal stirrup that scotch part is driven to be rotated to the direction of motion along corresponding journal stirrup by shaft of the 4th shaft, in this way, scotch
It is subjected to displacement in the circumferential direction of runner.By the way that support portion is arranged in the rack of catching device, portion supported above is scotch
Effect of contraction has been subjected to displacement in the circumferential direction of runner, i.e. support portion is used to provide the supporting surface of support scotch, in this way,
It can be achieved to transmit the power for locking runner directly between runner and rack by scotch, and flipping block itself, constriction and machine
