Concrete meaning of the language in the utility model.
In addition, as long as technical characteristic involved in the utility model different embodiments disclosed below is each other
Conflict can is not formed to be combined with each other.
Figures 1 and 2 show that the front view and part of the fall arrest hanging basket that a kind of specific embodiment of the utility model provides
Enlarged drawing.As illustrated, a kind of fall arrest hanging basket, including hanging basket body 1 and along the activity direction of hanging basket body 1 extension the
One column 2 and the second column 3；Corresponding first column 2 in the top of the hanging basket body 1 and second column 3 are provided with the
After one motion bar 4 and the second motion bar 5, first motion bar 4 and described one end of second motion bar 5 are be hinged with pull rope phase
Even, the other end is movably connected on the hanging basket body 1, and included angle A can between first motion bar 4 and second motion bar 5
Become.The chute 6 extended along bar is provided with first motion bar 4 and second motion bar 5, the hanging basket body 1 is right
First motion bar 4 and second motion bar 5 is answered to be provided through the rotating shaft 7 of the chute 6, the rotating shaft 7 can be along institute
Chute 6 is stated to slide.
The fall arrest hanging basket is also included located at the stage clip between first motion bar 4 and second motion bar 5, institute
State the direction motion that the elastic force of stage clip makes first motion bar 4, second motion bar 5 increase towards included angle A.Such as Fig. 3 and
Shown in Fig. 4, first motion bar 4 and the end of the second motion bar 5 are provided with U-shaped card pawl, and the U-shaped card pawl is sticked in described
First column 2 and the periphery of the second column 3, first column 2 and second column 3 are correspondingly arranged on along bearing of trend
Some clamping projections 9, first column 2 and second column 3 are correspondingly arranged on some for the stop U along bearing of trend
The bulge-structure that type claw glides.
Normal condition is under tractive force effect, and included angle A diminishes, first motion bar 4 and second motion bar 5 and institute
The first column 2 and the second column 3 are stated without active force, the stage clip is by first motion bar 4 and second motion bar 5
Extruding is shunk, and stores elastic potential energy；When there is unexpected pull rope disconnection, first motion bar 4 and second motion bar 5 lose
Tractive force is gone to act on, the stage clip discharges elastic potential energy, and acceleration makes included angle A become big, makes braking much sooner.First activity
U-shaped claw on bar 4 and second motion bar 5 is connected in the bulge-structure of first column 2 and second column 3
On, braking is realized, is automatically prevented from hanging basket free-falling.The power that this fall arrest hanging basket is used to brake is not limited to use prior art
In frictional force, additionally provide using the selection for supporting dynamic braking, it is safer using holding power compared to using frictional force brakes
Reliably, and the bigger hanging basket of loading capacity is gone for.
It is pointed out that the connected mode of the motion bar and the hanging basket body 1 is not limited to above-mentioned embodiment, make
For another embodiment, corresponding first motion bar 4 of the hanging basket body 1 and second motion bar 5 are provided with first
Slide and second slide, the first slide and the second slide can be along first columns 2 and the spacing of the second column 3
Direction is slided, between the first slide and first motion bar 4 and the second slide and second motion bar 5 it
Between be rotatably connected.
It is pointed out that described be used to accelerate the elastic component 8 of the included angle A increase to be not limited to when losing tractive force
Stage clip is stated, as shown in figure 5, as another embodiment, the elastic component 8 can also be located at first motion bar 4
And/or the extension spring between second motion bar 5 and the hanging basket body 1.Under tractive force effect, included angle A diminishes, described
First motion bar 4 and second motion bar 5 and the column 3 of the first column 2 and second are without active force, and the extension spring is by institute
The stretching of motion bar and the hanging basket body 1 is stated, stores elastic potential energy；When pull rope disconnects, first motion bar 4 and described
Second motion bar 5 loses tractive force effect, and the extension spring discharges elastic potential energy, makes the motion bar to the side of hanging basket body 1
To motion, acceleration makes included angle A become big.
It is pointed out that it is not limited to use the clamping in above-mentioned embodiment to match somebody with somebody between the motion bar and the column
Close provide brake power, can also be using frictional force brakes, as the end of the first motion bar 4 described in another embodiment with
Between first column 2, and, friction structure is provided between the end of the second motion bar 5 and second column 3,
When pull rope disconnects, included angle A increase, first column 2 and first motion bar 4 and second column 3 with
The friction structure between second motion bar 5 contacts with each other, according to the structure of the first motion bar 4 and the second motion bar 5
Feature understands that included angle A may proceed to become big in the presence of frictional force and hanging basket total force, and included angle A becomes conference and frictional force is entered
One step increases, the final stop motion of hanging basket body 1.It can thus be seen that the brake force of hanging basket not depends in the technical program
In the elastic force of elastic component 8, but depending on the total force of hanging basket body 1, braking are more reliable.
It is pointed out that some cards that first column 2 and second column 3 are correspondingly arranged on along bearing of trend
Projection 9 is connect, and first motion bar 4 and the end of the second motion bar 5 are provided with what can be engaged with the clamping projection 9
Interface arrangment 10 is not limited to the rigidity cooperation in above-mentioned embodiment, and as another embodiment, the clamping projection 9 is provided with
Chamfering, the interface arrangment 10 and/or clamping projection 9 are elastic rubber material, and the inner bottom surface of hanging basket body 1 is
Flexible material for buffering is made, and during braking, clamping projection 9 coordinates progressively to enter hanging basket by multi stage resilient interface arrangment 10
Row braking, according to momentum theorem, reduces the impulsive force suffered by loading in hanging basket, is advantageous to protect breakables.
Obviously, above-described embodiment is only intended to clearly illustrate example, and is not the restriction to embodiment.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of change or
Change.There is no necessity and possibility to exhaust all the enbodiments.And the obvious change thus extended out or
Among the protection domain that variation is created still in the utility model.
