Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.Based on the implementation in the present invention, those of ordinary skill in the art exist
All other embodiment obtained under the premise of creative work is not made, shall fall within the protection scope of the present invention.
As depicted in figs. 1 and 2, a kind of sling system based on spring-damper, which subtracts, shakes rope tensioning apparatus, the hoist system
System includes circumferential is uniformly distributed there are three the hanging scaffold 2 of spring-damper 1 and for generating lifting force suffered by the sling system
Two lifting ropes 3, described 3 one end of lifting rope connect with crane arm, and the other end is from the pulley being connected on the hanging scaffold 2
4 lower ends are laid out to be connect with the crane arm, forms two parallel rope sections, and the pulley 4 passes through pulley yoke 5 and the hanging scaffold
The connection of 2 upper ends；
The spring-damper 1 includes:
Damper shell 11 has the plunger shaft 12 coaxial with the spring-damper 1, and one end and subtracting shakes the company of rope 6
Connect, it is described subtract to shake 6 other end of rope and subtract rocker arm with crane connect；
Piston 13 is located in the plunger shaft 12 and can slide along 1 axis direction of spring-damper；
Connecting rod 14 is located on 1 axis of spring-damper, and one end is connect with the piston 13, and the other end is from institute
11 other end of damper shell is stated to be pierced by and cut with scissors by hinge column 15 thereon with the otic placode 21 being located on 2 side wall of hanging scaffold
It connects；
Spring 16 is located in the plunger shaft 12 and is surrounded on 14 outside of connecting rod, when the piston 13 is with described
Connecting rod 14 when overhanging mobile the spring 16 compressed；
12 inner wall of plunger shaft also has the safety lock for limiting 1 excessive tensile of spring-damper, the peace
Quan Suowei is coaxial with the spring-damper 1 and externally protrudes out in the annular protrusion 17 of 12 inner wall of plunger shaft, and internal diameter is less than institute
13 outer diameter of piston is stated, the piston 13 is played when the piston 13 is moved to the annular protrusion 17 and hinders mobile work
With avoiding to the spring 16 into one since the annular protrusion 17 has certain distance apart from 12 end of plunger shaft
Step compression；
The angle in the direction of lifting force suffered by 1 axis of spring-damper and the sling system is greater than 0 ° less than 90 °；
Three subtract and shake 6 space of rope in triangular pyramid, and every subtracts to shake and is fitted with spring-damper 1 on rope 6, when under hanging scaffold 2
The suspension hook 7 at end slings weight, due to receiving influence of the hoist with natural situation itself, can sling system be played pendulum, institute
Subtracted with every and shake rope 6 and will receive the tension of size variation, when its tension becomes larger suddenly, connecting rod 14 can haul piston 13 and compress bullet
Spring 16, while buffering subtracts and shakes the increased tension suddenly of rope 6, moreover it is possible to make to subtract and shake rope 6 and be in tensioning state, ensure that subtract and shake effect
Fruit；When tension increases to certain value, effect of the piston 13 by safety lock, and no longer move, to play protection spring
The effect of damper 1；And when subtract shake rope 6 by smaller tension force effect when, piston 13 will receive the effect of 16 tension of spring
It hauls connecting rod 14 to move towards opposite direction, can make to subtract and shake the holding tensioning state of rope 6, while guarantee anti-rolling effect.
Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
Pipe present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: its according to
