The present invention specific work process be：The present invention is arranged between electric block and i-shaped beams 1, electric block peace
Mounted in the underface of fixed plate 12, during electric block hoisting heavy, power is provided by motor when due to lifting, because
This can reach higher rotating speed in motor in a flash, and will appear steel wire rope during hoisting heavy at this time stretches tight suddenly
Tightly, electric block is playing a lift heavy after then causing an impact to steel wire rope, installation of the invention during hoisting heavy
It tensing in an instant when steel wire rope moment during object, steel wire rope just has the tendency that scrolling up and lifting weight at this time,
But weight gravity is excessive at this time and motor will not stall, in the mistake of the continuous tense wire rope of power for the tightening steel wire rope that motor provides
Cheng Zhong, fixed plate 12 have the tendency that moving downward, and during fixed plate 12 moves downward, fixed plate 12 moves downward drive
Second tension spring 13 and the first telescopic rod 14 move downward simultaneously, and the stretching that pulling force at this time does not reach the second tension spring 13 is wanted
It asks, the second tension spring 13, which moves downward, drives second gear 8 to move downward, and second gear 8 engages two during moving downward
A first gear 2 simultaneously makes two first gears 2 rotate in same direction, in the process since there are downward pulling force in second gear 8
And with the trend moved downward, two first gears during two first gears 2 move downward are engaged in second gear 8
2 can not only rotate but also can be moved to the both sides of second gear 8.
During second gear 8 engages the rotation of first gear 2, the rotation of first gear 2 drives the first axis pin 7 to follow
First gear 2 rotates, the first axis pin 7 during rotation, the both ends of the first axis pin 7 along annular groove 4 block 6 effect
It is lower constantly to compress the first compression spring 5, as the first compression spring 5 is constantly compressed during compressing the first compression spring 5, the first compression spring 5
The reaction force that can be provided also can be bigger, and the reaction that the first compression spring 5 can be provided can hinder the rotation of first gear 2,
To hinder second gear 8 to move downward, during first gear 2 rotates, the runner 3 of 2 both ends of the surface of first gear will not
It is rotated because of the rotation of first gear 2, therefore during second gear 8 moves downward, since the first compression spring 5 is compressed
The pressure absorbed is the buffer unit of the first order.
During second gear 8 moves downward, since second gear 8 is that disc type gear is therefore continuous in second gear 8
It is will produce during whereabouts to both sides and pushes the power that first gear 2 moves, transported respectively to its respective side in two first gears 2
In dynamic process, two runners 3 of each 2 both ends of the surface of first gear are fixed on, are moved along sliding rail 20, in runner 3 to two
During side is moved, 9 under tension of the first tension spring being horizontally fixed on two runners 3 of 2 homonymy of first gear, and to two
Side starts to stretch, and the first tension spring 9 is located on the first tension spring 9 during being stretched on second telescopic rod 10 at both ends
Two the first hollow circular-tubes 27, also produce relative sliding, the sliding in second sliding slot 30 of countercheck rod 29 during sliding herein,
When the center of circle that second gear 8 moves to two first gears 2 of its center of circle and both sides is in same level, at this time first
Tension spring 9 is stretched to extreme position, and the outside diameter of second gear 8 is just in contact with the sliding rail 20 of 8 lower section of second gear, at this time
Second gear 8 does not have droping space and keeps the state that no longer falls, in the process, the first tension spring 9 be squeezed power and to
Both sides extend, while providing reaction force and acting directly on steel wire rope during tense wire rope for absorbing electric block
On power, this process be second level buffer unit.
When second gear 8 compresses the sliding rail 20 of its lower end, if weight is raised not yet at this time, crimped on steel wire rope
Power still will continue to increase in the case where motor persistently rotates, therefore only fixed plate 12 continues to move downward and could meet steel wire rope
On the effect that is buffered of power, after second gear 8 no longer moves down, fixed plate 12 continues to move down, at this time steel wire
The pulling force being subject on rope, which has been provided with, to be pulled open the condition of the second tension spring 13 and is fixed on second with moving down for fixed plate 12
The second tension spring 13 on the outrigger shaft 11 in 8 outside of gear follows fixed plate 12 to move down and realizes the stretching of length, the
First telescopic rod 14 of two tension springs, 13 left and right sides is extended with the elongation of the second tension spring 13, in the elongation of the first telescopic rod 14
In the process, two are mutually sleeved together when the second tension spring 13 is stretched to extreme position, on the first telescopic rod 14 second is empty
Heart pipe 28 also produces relative sliding, and during two the second hollow pipes 28 produce relative sliding, countercheck rod 29 is slided second
Slot 30 slides, and when the second tension spring 13 is stretched to extreme position, countercheck rod 29 slides into the slot of second sliding slot 30 in second sliding slot 30
Wall edge simultaneously realizes the compression of countercheck rod 29 and second sliding slot 30 and realizes braking, and the stretching of the second tension spring 13 in the process has
Effect has buffered stretching action of the motor rotation to steel wire rope, this process is third level buffer unit.
During fixed plate 12 moves downward, two struts 18 on the second axis pin 21 are hinged in third tension spring 19
Under the action of it is constantly mobile to centre, during strut 18 is mobile to centre the idler wheel 31 of 18 lower end of strut always with fixation
The upper surface joint of plate 12, idler wheel 31 can be rotated constantly during strut 18 moves, mistake of the strut 18 in rotation
It is to turn to the inside around the second axis pin 21 in journey, idler wheel 31 can be squeezed constantly during 12 inside side roll of fixed plate and be set
Voussoir 17 below strut 18 is due to 31 inside side roll of idler wheel, and idler wheel 31 can contact and think therewith first during rolling
The inclined-plane of that close voussoir 17, during 31 continuous rotational motion of idler wheel, idler wheel 31 can be applied to voussoir 17 to
Under power, under the action of this downward power so that the voussoir 17 contacted moves downward, and voussoir 17 moves downward band
Dynamic, the voussoir that the third compression spring 32 of 17 lower section of voussoir is moved down compresses, and third compression spring 32 is compressed, living during giving again
Movable plate 15 also will appear the trend moved downward, but since the elasticity that the elastic strength of the second compression spring 16 is more than third compression spring 32 is strong
The degree amplitude that therefore movable plate 15 falls during compression can keep very little, and third compression spring 32, which is shunk, makes the upper of voussoir 17
End is placed in the position horizontal with 12 upper surface of fixed plate phase, and voussoir 17 is not in the rotation that can stop idler wheel 31 i.e. strut 18 at this time
The trend inwardly moved so that be not in the device for hindering it to fall during fixed plate 12 moves downward, but when rolling
Wheel 31 is wanted to rotate backward i.e. strut 18 and is wanted when move outward, under the barrier effect in 17 non-inclined face of voussoir so that
Idler wheel 31 cannot rotate to realize the trend that blocking strut 18 is moved to both sides.
When the present invention complete buffer unit task after, at this time steel wire rope just can hoisting heavy, in the mistake of hoisting heavy
Cheng Zhong may have the structure shaken up and down and therefore ensure that electric block can only in hanged weight when just lifting due to weight
Downwards cannot be upward, after completing lifting task, by opening driving motor 26, the rotation of driving motor 26 drives third gear
The rotation of 25 rotations, third gear 25 drives the rack 24 of engagement on it to move downward, because the driving motor 26 of both sides is
It rotates in same direction simultaneously, this makes the rack 24 of both sides while moving downward during rack 24 moves downward, drive activity
Plate 15 moves downward, and movable plate 15 moves downward the second compression spring 16 for compressing 15 lower section of movable plate, and it is made to keep by compression shape
State can be moved downward by third compression spring 32 with dynamic voussoir 17 during movable plate 15 falls, when voussoir 17 moves to it
When upper end and the upper surface level of fixed plate 12, voussoir 17 can no longer stop that strut 18 moves outward.
After voussoir 17 can no longer stop that strut 18 moves outward, under the collective effect of compressed multigroup spring
Realize fixed plate 12 move upwards, fixed plate 12 move upwards so that two idler wheels 31 laterally rotate and realize strut 18 to
Movement outside, spring and gear in buffer unit are restored to initial position, finally stop driving motor 26 in the second compression spring 16
Under the action of so that movable plate 15 be restored to original position.
The process moved downward by second gear 8 engages and first gear 2 is driven to rotate, the rotation band of first gear 2
Dynamic the first axis pin 7 being fixed in first gear 2 rotates together, and the first axis pin 7 compresses the in annular groove 4 during rotating
One compression spring 5 realizes first order buffering；During second gear 8 moves downward, the runners 3 of both sides by external force to its
The pulling force that respective side stretches the first tension spring 9 during moving and the first tension spring more than 9 is overcome to provide realizes second level buffering；Gu
Stretching the second tension spring 13 and the first telescopic rod 14 and the second tension spring 13 of realization that fixed board 12 moves downward drive second gear 8 downward
Third level buffering is realized in movement.
It is realized by the vertical stretching of the bending compression of the first compression spring 5, the cross directional stretch of the first tension spring 9 and the second tension spring 13
The mutual cooperation of multigroup spring structure is directed to the weight of different weight to realize in the buffering of different levels, then this buffering course
Always there is the continual trend moved downward in fixed plate 12, by fixed plate 12 move down realize electric block to
Lower movement meets and is acted in the multi-buffer for realizing steel wire rope during motor rotation by moving down electric block.
The cushion effect that the first compression spring 5 in the invention can be provided is minimum, and the cushion effect that the first tension spring 9 provides is more than first
Compression spring 5, the cushion effect that the second tension spring 13 can be provided is maximum, therefore the goods of different weight can be directed to when the present invention works
Object plays cushioning effect, and the first compression spring 5 is worked at the same time with the first tension spring 9, but the mobile distance of rotation is more than and moves down when working
Distance, therefore the first compression spring 5 plays cushioning effect first in peer, when the first compression spring 5 and the first tension spring 9 move to the limit
When position, the second tension spring 13 starts to stretch, and ensures that three-level buffer unit is to cooperate that interval is not present.
In buffering course, due to second gear 8 diameter be more than first gear 2 second gear 8 move downward just
Stage beginning, second gear 8 engage the arc length that first gear 2 rotates and are greater than 8 drop of second gear, this process is first
Grade buffer status, after second gear 8 moves downward a distance, second gear 8 pushes the distance of first gear 2 to become to both sides
Greatly, this process buffers for the second level, therefore first order buffering is inseparable and interrelated with second level buffering.
Realize that fixed plate 12 can only be realized in the operating condition by the cooperation of two rotatable struts 18 and voussoir 17
Inwardly movement is to improve the stability in electric block hoisting heavy and when putting down weight
The present invention realizes the electrodeless cushioning effect during being lifted by crane to different weights by the spring assembly of different elasticity,
Efficiently solve the problems, such as electric block in start-up course due to lift by crane it is too fast and caused by service life of steel wire rope it is short, this hair
It is bright novel, clever structure, highly practical.
