The present invention specific work process be:The present invention is arranged between electric block and i-shaped beamses 1, electric block peace Mounted in the underface of fixed plate 12, during electric block hoisting heavy, power is provided by motor during due to lifting, because This just can reach higher rotating speed in motor in a flash, now occur that steel wire rope stretches tight suddenly during hoisting heavy Tightly, electric block is playing a lift heavy after then causing an impact to steel wire rope, installation of the invention during hoisting heavy Tensed in an instant when steel wire rope moment during thing, now steel wire rope has just had the trend for scrolling up and lifting weight, But now weight gravity is excessive and motor will not stall, in the mistake for the continuous tense wire rope of power for tightening up steel wire rope that motor provides Cheng Zhong, fixed plate 12 have the trend moved downward, and during fixed plate 12 moves downward, fixed plate 12 moves downward drive Second extension spring 13 and the first expansion link 14 move downward simultaneously, and the stretching that pulling force now is not reaching to the second extension spring 13 will Ask, the second extension spring 13, which moves downward, drives second gear 8 to move downward, and second gear 8 engages two during moving downward Individual first gear 2 simultaneously rotates in same direction two first gears 2, in the process due to downward pulling force be present 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 bearing pin 7 to follow First gear 2 rotates, the first bearing pin 7 during rotation, the both ends of the first bearing pin 7 along annular groove 4 block 6 effect It is lower constantly to compress the first stage clip 5, as the first stage clip 5 is constantly compressed during the first stage clip 5 is compressed, the first stage clip 5 The reaction force that can be provided also can be bigger, and the reaction that the first stage clip 5 can be provided can hinder the rotation of first gear 2, So as to hinder second gear 8 to move downward, during first gear 2 rotates, the runner 3 of the both ends of the surface of first gear 2 will not Rotated because of the rotation of first gear 2, therefore during second gear 8 moves downward, because the first stage clip 5 is compressed The pressure absorbed is the buffer unit of the first order.
During second gear 8 moves downward, because second gear 8 is that disc type gear is therefore continuous in second gear 8 The power for promoting first gear 2 to move to both sides can be produced during whereabouts, is transported respectively to its respective side in two first gears 2 In dynamic process, two runners 3 of each both ends of the surface of first gear 2 are fixed on, are moved along slide rail 20, in runner 3 to two During side is moved, the under tension of the first extension spring 9 that is horizontally fixed on two runners 3 of the homonymy of first gear 2, and to two Side starts to stretch, and the first extension spring 9 is located at during being stretched on the second expansion link 10 in the first extension spring 9 to both ends Two hollow pipes 26, relative slip is also produced, countercheck rod 27 slides in the second chute 28 during sliding herein, when second When the center of circle that gear 8 moves to two first gears 2 of its center of circle and both sides is in same level, now the first extension spring 9 It is stretched to extreme position, the slide rail 20 of the outside diameter of second gear 8 just with the lower section of second gear 8 is in contact, and now second Gear 8 does not have droping space and keeps the state that no longer falls, and in the process, the first extension spring 9 is squeezed power and to both sides Extension, while reaction force is provided and acted directly on for absorbing electric block during tense wire rope on steel wire rope Power, this process are second level buffer unit.
When second gear 8 compresses the slide rail 20 of its lower end, if now weight is not raised also, crimped on steel wire rope Power still may proceed 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, now steel wire The pulling force being subject on rope has been provided with pulling open the condition of the second extension spring 13, with moving down for fixed plate 12, is fixed on second The second extension spring 13 on the outrigger shaft 11 in the outside of gear 8 follows fixed plate 12 to move down and realizes the stretching of its length, the First expansion link 14 of the left and right sides of two extension spring 13 extends with the elongation of the second extension spring 13, in the elongation of the first expansion link 14 During, two are mutually sleeved together when the second extension spring 13 is stretched to extreme position, on the first expansion link 14 second is empty Heart pipe 28 also produces relative slip, and during two the second hollow pipes 28 produce relative slide, countercheck rod 29 is slided second Groove 30 slides, and when the second extension spring 13 is stretched to extreme position, countercheck rod 29 slides into the groove of the second chute 30 in the second chute 30 Wall edge simultaneously realizes the compression of the chute 30 of countercheck rod 29 and second and realizes braking, and the stretching of the second extension spring 13 in the process has Effect has buffered stretching action of the motor rotation to steel wire rope, and this process is third level buffer unit.
During fixed plate 12 moves downward, two poles 18 on the second bearing pin 21 are hinged in the 3rd extension spring 19 In the presence of it is constantly mobile to centre, pole 18 to it is middle it is mobile during the lower end of pole 18 roller 31 all the time with fixation The upper surface joint of plate 12, roller 31 can be rotated constantly during pole 18 is moved, mistake of the pole 18 in rotation It is to be turned to the inside around the second bearing pin 21 in journey, roller 31 can constantly be extruded during 12 inside side roll of fixed plate and put Voussoir 17 below pole 18 is due to 31 inside side roll of roller, and roller 31 can first be contacted and thought therewith during rolling The inclined-plane of that close voussoir 17, during 31 continuous rotational motion of roller, roller 31 can be applied to voussoir 17 to Under power, in the presence of this downward power so that the voussoir 17 contacted moves downward, and voussoir 17 moves downward band Dynamic, the voussoir that the 3rd stage clip 32 of the lower section of voussoir 17 is moved down is compressed, and the 3rd stage clip 32 is compressed, living during giving again The trend moved downward also occurs in dynamic plate 15, but because the elastic strength of the second stage clip 16 is more than the elasticity of the 3rd stage clip 32 by force The degree amplitude that therefore portable plate 15 falls during compression can keep very little, and the 3rd stage clip 32, which shrinks, causes the upper of voussoir 17 End is placed in the position with the upper surface scent flask of fixed plate 12, and now voussoir 17 can not stop the rotation i.e. pole 18 of roller 31 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 when i.e. pole 18 wants outside lateral movement, causes under the barrier effect in the non-inclined face of voussoir 17 Roller 31 can not rotate stops trend of the pole 18 to two lateral movements so as to realize.
When the present invention complete buffer unit task after, now steel wire rope just can hoisting heavy, in the mistake of hoisting heavy Cheng Zhong, there may be the structure shaken up and down when just lifting due to weight and therefore ensure that electric block can only in hanged weight Downwards can not be upward, after lifting task is completed, by opening motor 26, the rotation of motor 26 drives the 3rd gear 25 rotate, and the rotation of the 3rd gear 25 drives the rack 24 being engaged on thereon to move downward, because the motor 26 of both sides is Rotate in same direction simultaneously, this causes the rack 24 of both sides while moved downward during rack 24 moves downward, drive activity Plate 15 moves downward, and portable plate 15 moves downward the second stage clip 16 for compressing the lower section of portable plate 15, and it is kept by compression shape State, it can be moved downward during portable plate 15 falls by the 3rd stage clip 32 with dynamic voussoir 17, when voussoir 17 moves to it When upper end and the upper surface level of fixed plate 12, voussoir 17 can no longer stop 18 outside lateral movement of pole.
After voussoir 17 no longer can stop 18 outside lateral movement of pole, under the collective effect of compressed multigroup spring Realize that fixed plate 12 is moved upwards, the upward motion of fixed plate 12 two rollers 31 are laterally rotated and realize pole 18 to Movement outside, spring and gear in buffer unit return to initial position, finally stop motor 26 in the second stage clip 16 In the presence of cause portable plate 15 return to original position.
The process moved downward by second gear 8 engages and drives first gear 2 to rotate, the rotational band of first gear 2 Dynamic the first bearing pin 7 being fixed in first gear 2 rotates together, and the first bearing pin 7 compresses the in annular groove 4 during rotating One stage clip 5, realize that the first order buffers;During second gear 8 moves downward, the runner 3 of its both sides by external force to its The pulling force that respective side stretches the first extension spring 9 during moving and overcomes the first extension spring more than 9 to provide, realize that the second level buffers;Gu The second extension spring of stretching 13 that fixed board 12 moves downward and the first expansion link 14 simultaneously realize that the second extension spring 13 drives second gear 8 downward Motion, realize that the third level buffers.
Realized by the vertical stretching of the bending compression of the first stage clip 5, the cross directional stretch of the first extension spring 9 and the second extension spring 13 Multigroup spring structure cooperates for the weight of different weight so as to realize in the buffering of different levels, then this buffering course All the time the continual trend moved downward be present in fixed plate 12, by fixed plate 12 move down realize electric block to Lower movement, meet to act in the multi-buffer for realizing steel wire rope by moving down electric block during motor rotates.
The cushion effect that the first stage clip 5 in this invention can be provided is minimum, and the cushion effect that the first extension spring 9 provides is more than first Stage clip 5, the cushion effect that the second extension spring 13 can be provided is maximum, therefore the goods of different weight can be directed to when the present invention works Thing plays cushioning effect, and the first stage clip 5 works simultaneously with the first extension spring 9, but rotates mobile distance when working and be more than and move down Distance, therefore the first stage clip 5 plays cushioning effect first in peer, when the first stage clip 5 and the first extension spring 9 move to the limit During position, the second extension spring 13 starts to stretch, and it is to cooperate that interval is not present to ensure three-level buffer unit.
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 the drop of second gear 8, and this process is first Level buffer status, after second gear 8 moves downward a segment distance, second gear 8 promotes 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 poles 18 and voussoir 17 Stability when inwardly motion is so as to improve in electric block hoisting heavy and put down weight
The present invention realizes the electrodeless cushioning effect during being lifted by crane to different weights by different elastic spring assemblies, effectively 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, structure of the present invention Think novelty, clever structure, practical.
