Abstract
The utility model provides a mobile crane landing leg hose locking device with adjustable, is including fixing the mount pad on mobile crane fixed leg, it has two holes of running through to open on the mount pad, still include two thongs income downthehole adjusting screw, the advancing of landing leg hydro -cylinder, oil return hose are connected in two adjusting screw heads respectively, the adjusting screw afterbody all overlaps there is the spring, just uses to compress tightly with adjusting screw complex adjusting nut. Adopt adjusting the mode of compression spring decrement and coming the taut hose of trailing, what kind of the cornerite of no matter trailing hose and hose pulley takes place changes, and compression spring's decrement can compensate this relative motion volume all the time, makes to trail the hose and paste tight hose pulley and guide pulley all the time, prevents the hose damage that drops.
Description
Technical field
The utility model relates to a kind of loosening device of automobile crane supporting leg flexible pipe.
Background technology
Along with the continuous increase of elevating capacity of derrick car, in requirement, tonnage automobile crane adopts two joints or two to save above horizontal support legs, and wherein two horizontal synchronization telescope box supporting legs use the most extensive at home and abroad.
In two horizontal supporting leg retractable mechanisms, pipe is followed the tracks of in the many employings of vertical support oil cylinder oil inlet and oil return flexible pipe, because horizontal support legs follows the tracks of the easy loose or dislocation of flexible pipe in flexible process, often occurs follow the tracks of the squeezed evil idea of pipe and cause hoisting crane normally to use.
Utility model content
For the technical matters of above-mentioned existence, the utility model provides a kind of adjustable automobile crane support flexible pipe locking device to prevent the entering of support oil cylinder, oil return hose loose or dislocation in landing leg stretching process.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of adjustable automobile crane support flexible pipe locking device, comprises the mount pad be fixed on car hosit fixed supporting leg, described mount pad has two holes run through; Also comprise two adjusting screw(rod)s inserted in described hole, the entering of support oil cylinder, oil return hose connect respectively at two adjusting screw(rod) heads; Described adjusting screw(rod) afterbody all overlaps and has spring, and compresses with the setting nut coordinated with adjusting screw(rod).
Improve as one, described adjusting screw(rod) afterbody is square-column-shaped.Rotating adjusting nut after convenient clamping.
Improve as one, every root adjusting screw(rod) afterbody is provided with two setting nuts.Mutually can carry on the back tight, prevent nut from dropping in the process used or relaxing.
Usefulness of the present utility model is: the locking device with said structure, adopt and regulate the mode of Compress Spring amount of compression to strain tracking flexible pipe, what kind of occurs the cornerite no matter following the tracks of flexible pipe and hose sheave changes, the amount of compression of Compress Spring can compensate this relative motion amount all the time, make tracking flexible pipe be adjacent to hose sheave and leading sheave all the time, prevent flexible pipe to come off damage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the utility model scheme of installation.
Fig. 3 is that the utility model installs birds-eye view.
Mark in figure: 1 support oil cylinder, 4 leading sheaves, 5 oil inlet hoses, 5' oil return hose, 6 one joint movable supporting legs, 7 leading sheaves, 8 two joint movable supporting legs, 9 fixed supporting legs, 10 hose sheaves, 11 T-pipe joints, 12 adjusting screw(rod)s, 13 mount pads, 14 bolt of rear end plates, 15 springs, 16 setting nuts.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 2 and Figure 3, in, in the design of large-tonnage car hosit, extensively adopt two joint movable supporting legs modes, its vertical support oil cylinder 1 oil inlet hose 5, oil return hose 5' many employings tracking flexible pipe.Because a joint movable supporting legs 6 and two joint movable supporting legs 8 are in telescopic process, oil inlet hose 5, oil return hose 5' coiling length have the change of twenties millimeters, therefore must ensure that oil inlet hose 5, oil return hose 5' tightly wrap all the time on guide roller 4 and hose sheave 10, otherwise oil inlet hose 5, oil return hose 5' can depart from hose sheave 10 and squeezed bad.
As shown in Figure 1, the utility model comprises and utilizes bolt of rear end plate 14 to be fixed on mount pad 13 on car hosit fixed supporting leg 9, described mount pad 13 has two holes run through; Also comprise two adjusting screw(rod)s 12 inserted in described hole, the oil inlet hose 5 oil return hose 5' of support oil cylinder 1 utilizes T-pipe joint 11 to be connected with two adjusting screw(rod) 12 heads respectively; Described adjusting screw(rod) 12 afterbody all overlaps and has spring 15, and compresses with the setting nut 16 coordinated with adjusting screw(rod) 12.Adjusting screw(rod) 12 afterbody is preferably square-column-shaped.Every root adjusting screw(rod) 12 afterbody can be provided with two setting nuts 16.
During work, can rotating adjusting nut 16 to the right after clamping the square-column-shaped position of adjusting screw(rod) 12 afterbody, the compressive force of regulating spring 15, to strain oil inlet hose 5 oil return hose 5', is adjacent to hose sheave 10 and leading sheave 7 all the time, prevents flexible pipe from coming off.During telescopic outrigger, because oil inlet hose 5 oil return hose 5' and hose sheave 10 cornerite constantly change, cause oil inlet hose 5 oil return hose 5' lower end and two to be saved to have between movable supporting legs 8 relative motion among a small circle, the amount of compression of spring 15 can compensate this relative motion amount, make oil inlet hose 5 oil return hose 5' be adjacent to hose sheave 10 and leading sheave 4 all the time, prevent flexible pipe to come off damage.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
