Hydraulic pressure gauntry crane
The invention relates to weight-lifting equipment, and concrete a kind of walking beam with raised line and the cooperation of duplicate rows travelling wheel forms hydraulic pressure gauntry crane.
Row (hang) car, crane, overhead traveling crane be all people to hoisting crane general call, driving is substantially the same with present our alleged hoisting crane.Substantially there are two classes: a class is centralized driving, with an electrical motor, drive long pass moving axis to drive the adhesion wheel on both sides; Another kind of for driving respectively, be both sides adhesion wheel each by a direct motor drive.The more employing drg of medium and small crane in bridge type, retarder and motor unit incorporated " three-in-one " type of drive, the ordinary bridge crane of big elevating capacity is for ease of install and adjust, and actuating device often adopts universal coupling.
Existing gauntry crane is all that track load-carrying capacity is smaller, can not meet heavy weight requirement, and major cause is that existing track load-carrying capacity is lower.
Summary of the invention
The object of the invention is can not meet high-mechanic and be convenient to dismantle the problem in mobile building site with gauntry crane for existing engineering, and a kind of hydraulic pressure gauntry crane is provided.This device can significantly improve load-carrying capacity, and can be at any time dismounting and change field of employment.
For reaching above object, the technical scheme that the invention adopts is:
A hydraulic pressure gauntry crane, comprises track, and track is provided with walking beam, walking beam is provided with two groups of totally four road wheels, described walking beam is framed structure, and each at least two road wheels side by side of the two ends of walking beam, are provided with walking guide position limiter between road wheel and track.
Described track is box beam structure, and walking guide position limiter comprises at least one raised line that is positioned at box beam upper center and is provided with along track bearing of trend, between two road wheels side by side, has groove between the wheel corresponding with raised line.
The two ends of described walking beam are respectively provided with two road wheels, between two road wheels of same one end, are groove.
Each track is provided with four walking beams, a hydraulic jack of every two groups of walking beams top holder, and each track is provided with two hydraulic jacks; Four groups form two secondary bearing beams of holder, form a hydraulic pressure gauntry crane with another main bolster.
Further, in described walking beam, one of them is active walking beam, each initiatively comprises two road wheels in the every one end of walking beam volume, parallel coaxial settings of two road wheels and being set in rotating shaft by key, between two road wheels, rotating shaft is arranged with spacing sleeve outward, the outside of road wheel is provided with clamping sleeve, and the two ends of clamping sleeve are provided with end cap, and end cap is provided with the oil hole towards bearing.
Further, in described walking beam, one of them is active walking beam, each every one end of initiatively walking comprises two road wheels, parallel coaxial settings of two road wheels and being set in rotating shaft by key, between two road wheels, rotating shaft is arranged with spacing sleeve outward, the outside of road wheel is provided with clamping sleeve, and the two ends of clamping sleeve are provided with end cap, and end cap is provided with the oil hole towards bearing.
Further, in described walking beam, one of them is driven walking beam, each every one end of driven walking comprises two road wheels, in the parallel coaxial setting of two road wheels and its, be arranged with bearing, bearing carrier ring is located in rotating shaft, the outside that between two bearings in inner side, rotating shaft is provided with spacing sleeve, bearing is outward provided with clamping sleeve, and the two ends of clamping sleeve are provided with end cap.
Principle of work and the beneficial effect of the invention show:
The invention mainly comprises track travel beam and guide rail.
Track adopts box beam structure, and between walking beam, is provided with walking guide position limiter, by track is carried out to large area words, can expand its area of contact, meanwhile, walking beam design be become to tower structure, two ends at walking beam arrange road wheel, make it can carry more weight.
Walking guide position limiter comprises the raised line being positioned on track, be combined with groove with raised line, the groove of the invention adopts road wheel to realize, such as two road wheels are set, between two road wheels, be groove, for coordinating raised line, like this, during walking, the direction that road wheel can extend along raised line is walked, and road wheel can not de-orbit.

The specific embodiment
The correlation technique content of not addressing below all can adopt or use for reference prior art.
In order to make those skilled in the art person understand better the technical scheme in the application, below in conjunction with the accompanying drawing in the embodiment of the present application, technical scheme in the embodiment of the present application is clearly and completely described, obviously, described embodiment is only the application's part embodiment, rather than whole embodiment.Embodiment based in the application, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all should belong to the scope of the application's protection.
Shown in Fig. 1,2,3, a kind of gauntry crane support walking beam, comprises initiatively walking beam 1 and passive walking beam 2.
Each walking beam comprises the beam body of frame type structure, and the two ends of beam body are provided with road wheel 3, and in the present embodiment, the road wheel 3 of every one end is provided with two side by side, the axis conllinear of two road wheels 3 and vertical with direction of travel.
Wherein initiatively in walking beam 1, two road wheels 3 that are positioned at same one end overlap 8 by key and are located in rotating shaft 9, are provided with spacing sleeve 10 between two road wheels, make between two road wheels, to have certain distance.
The two ends of road wheel 3 are provided with pad, are arranged with bearing 11 and supporting bearing seat on pad outer shaft, and bearing seat is fixed on the Liang Tishang of frame type structure.
In the both sides of bearing, be provided with dustproof end cap, dustproof end cap is provided with the oil hole towards bearing oiling.
Two road wheels 3 that are arranged in two ends of passive walking beam 2, road wheel 3 inner sides are arranged with bearing 4, and the outside that is in axial direction also provided with spacing sleeve 5, bearing in the inner side of two bearings is provided with clamping sleeve 7, and the outer end of clamping sleeve is provided with end cap 6.
In the present embodiment, be arranged with two bearings in each road wheel of passive beam, two bearing parts are also provided with spacing sleeve.
By above mode, in every one end of walking beam, be all provided with two road wheels like this, between two road wheels, there is certain space length.
On walking track, correspondingly with distance between every pair of road wheel be provided with a raised line, in walking process, raised line just in time in the distance between two road wheels, plays the object of location.
By this kind of mode, effectively improved the weight that walking beam can carry.
The above is only the application's preferred implementation, makes those skilled in the art can understand or realize the application.To the multiple modification of these embodiment, will be apparent to one skilled in the art, General Principle as defined herein can be in the situation that do not depart from the application's spirit or scope, realization in other embodiments.Therefore, the application will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
