Abstract
The utility model discloses a guiding and swinging preventive device of a lifting appliance of a crane, which comprises two guiding sleeves, wherein the guiding sleeves are fixedly connected with a trolley; cushioning devices are arranged on the guiding sleeves and comprise spring systems (or hydraulic systems); when the crane is started to run or is braked, the wobbing energy of the lifting appliance can be absorbed by the cushioning devices, and the swinging of the lifting appliance rapidly stops; the upper ends and the lower ends of the guiding sleeves are respectively provided with two groups of guide pulleys; the guide pulleys at the upper ends are fixed guide pulleys; the guide pulleys at the lower ends are movable guide pulleys which are connected with the cushioning devices; the cushioning devices control the movable guide pulleys to move; guiding bars are arranged inside the guiding sleeves; guide rails are arranged on the guiding bars; the guide pulleys can slide along the guide rails, thereby playing a role in smooth guidance; inner holes are arranged at the bottoms of the guiding bars and can be matched with locating cones on the lifting appliance; and the restriction of the guiding bars on the lifting appliance can be rapidly and conveniently released through the separation and reunion of the inner holes and the locating cones.
Description
Technical field
The utility model relates to a kind of guiding and the anti-device that waves, and relates to specifically a kind of guiding and anti-sway device of crane hanger, mainly is applicable in the lifting mechanism of handling machinery.
Background technology
At present, employed guiding and anti-sway mode are divided into two big classes in the prior art: the form that 1, adopts the rigidity guide rod, be characterized in to prevent effectively the suspender swing, but institute's handling material is heavy more, its inertia is just big more, thereby guide rod need do just big more, impact also bigger to the rising of operation, braking; 2, the form that adopts wire rope inclined-pulling to twine, steel cable that is twined and suspender and dolly all have bigger angle of inclination; This mode can reduce the rocking tendency of suspender to a certain extent, but effect is not very good, is only applicable to less demanding occasion.
Therefore, how realizing the steady guiding of suspender and preventing from waving is a technical problem that needs to be resolved hurrily in the lifting mechanism of crane, needs further to be improved.
The utility model content
The purpose of this utility model, existing suspender leads and the deficiency of anti-sway device in order to overcome exactly, proposes a kind of anti-wave reliably, rise Brake Energy buffering, energy automatic clutch, working service easily suspender guiding and anti-sway device.
The technical scheme in the invention for solving the technical problem is: a kind of crane hanger guiding and anti-sway device, comprise two fairleads, and fairlead and dolly are fixedly connected; Buffer unit is housed on the fairlead, and this buffer unit is made of spring system (or hydraulic system), when crane operation starting or braking, can be absorbed by spring system (or hydraulic system) the beat energy of suspender, stops rapidly the swing of suspender; The upper and lower end of fairlead respectively is equipped with two groups of directive wheels, wherein the directive wheel of upper end is stator wheel, the directive wheel of lower end is the activity-oriented wheel, and the activity-oriented wheel links with buffer unit, by the motion of the spring system in the buffer unit (or hydraulic system) control activity-oriented wheel; Guide post is housed in the fairlead, and guide post is provided with guide rail, and directive wheel can slide along guide rail, thereby plays the effect of steady guiding; The guide post bottom is provided with endoporus, can cooperate with the locating cone (circular cone or pyramid) on the suspender, by the clutch between them, can remove quickly and easily guide post to the constraint of suspender, break away from requirement thereby satisfy the suspender bottom, also can make things convenient for the maintenance of guider and suspender.
The utility model by assemble shock absorber on orienting sleeve, has absorbed the beat energy of suspender, waves thereby actv. is anti-, has simple in structurely, and folding is adorned convenient, easy to maintenance characteristics.The guiding of suspender of the present utility model and antiswing device when suspender rises or descend, can reduce rocking of suspender, play guide effect.When crane operation starting and braking, the hydraulic pressure in the device or the damping action of spring system can relax suspender to the impact of crane.After hoisting crane stopped, the hydraulic pressure in the device or the shock damping action of spring system can immediately stop waving of suspender, play pinpoint function.The clutch mode of outer cone (circular cone or pyramid) can be removed guide post quickly and easily to the constraint of suspender in adopted the guide post bottom.This kind structure both can be used for technologic suspender bottom and had broken away from requirement, also can be used for making things convenient for the maintenance of guider and suspender.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1 is dolly; 2 is guide post; 3 is stator wheel; 4 is fairlead; 5 is buffer unit; 6 are the activity-oriented wheel; 7 is suspender.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in the figure, a kind of crane hanger guiding and anti-sway device comprise two fairleads 4, and fairlead 4 is fixedly connected with dolly 1; Buffer unit 5 is housed on the fairlead 4, and this device is made of spring system (or hydraulic system), when crane operation starting or braking, can be absorbed by spring system (or hydraulic system) the beat energy of suspender 7, stops rapidly the swing of suspender 7; The upper and lower end of fairlead 4 respectively is equipped with two groups of directive wheels, wherein the directive wheel of upper end is stator wheel 3, the directive wheel of lower end is activity-oriented wheel 6, and activity-oriented wheel 6 links with buffer unit 5, by the motion of the spring system in the buffer unit 5 (or hydraulic system) control activity-oriented wheel 6; Guide post 2 is housed in the fairlead 4, and guide post 2 is provided with guide rail, and directive wheel can slide along guide rail, thereby plays the effect of steady guiding; Guide post 2 bottoms are provided with endoporus, can cooperate with the locating cone 8 on the suspender 7, by the clutch between them, can remove quickly and easily the constraint of 2 pairs of suspenders 7 of guide post, break away from requirement thereby satisfy suspender 7 bottoms, also can make things convenient for the maintenance of guider and suspender 7.
The guiding of suspender of the present utility model and antiswing device when suspender rises or descend, can reduce rocking of suspender, play guide effect.When crane operation starting and braking, the hydraulic pressure in the device or the damping action of spring system can relax suspender to the impact of crane.After hoisting crane stopped, the hydraulic pressure in the device or the shock damping action of spring system can immediately stop waving of suspender, play pinpoint function.The clutch mode of outer cone (circular cone or pyramid) can be removed guide post quickly and easily to the constraint of suspender in adopted the guide post bottom.This kind structure both can be used for technologic suspender bottom and had broken away from requirement, also can be used for making things convenient for the maintenance of guider and suspender.
