Abstract
The utility model provides a kind of coal winning machine adjust high cylinder, comprises cylinder barrel, cylinder bottom, hydraulic lock, and described hydraulic lock is distributed in cylinder bottom both sides, and hydraulic lock is fixedly connected with cylinder bottom; The hydraulic control spool of hydraulic lock is directly placed in after hydraulic lock is connected with cylinder bottom and forms confined space.Oil circuit is integrated on cylinder bottom by this Split type hydraulic lock, and adopt split type structure, significantly simplify the structure, reduce volume, simplify processing, manufacture cost obtains and significantly reduces.When the hydraulic lock of split-type structural breaks down, only need change the hydraulic lock of fault, do not have out of order hydraulic lock then can continue to use, easy to maintenance, service cycle shortens, improves effect, reduces cost of upkeep, and then the maintenance expenses in later stage have also been obtained and significantly reduces.
Description
Technical field
The utility model belongs to machinery manufacturing technology field, relates to a kind of coal winning machine adjust high cylinder.
Background technique
Current domestic coal winning machine adjust high cylinder all adopts built-in integral bidirectional hydraulic lock, the hydraulic lock of this form is the standing replacing part on adjust high cylinder, and complex structure, difficulty of processing are large, volume is large, cost is high, maintenance is inconvenient, repairing efficiency is long, costly, therefore be necessary that the structure of the adjust high cylinder to this kind is optimized, reduce costs and maintenance expenses.
Summary of the invention
The shortcoming of prior art in view of the above, the purpose of this utility model is to provide a kind of coal winning machine adjust high cylinder, for solving problems of the prior art.
For achieving the above object and other relevant objects, the utility model provides a kind of coal winning machine adjust high cylinder, comprises cylinder barrel, cylinder bottom, hydraulic lock,
Described hydraulic lock is distributed in cylinder bottom both sides, and hydraulic lock is fixedly connected with cylinder bottom; The hydraulic control spool of hydraulic lock is directly placed in after hydraulic lock is connected with cylinder bottom and forms confined space.
Described hydraulic lock also comprises screw plug, steel ball seat, and described screw plug is fixedly connected with steel ball seat, in the confined space that screw plug and steel ball seat are formed, sets gradually Returnning spring, spring seat and steel ball from screw plug to steel ball seat direction; O RunddichtringO is enclosed within steel ball seat, and combination seal gasket sleeve is on screw plug.
Described cylinder bottom and cylinder barrel seam; oil connection and protection of oil pipes cover respectively with cylinder barrel seam; oil pipe is between protection of oil pipes cover and cylinder barrel; oil pipe and oil connection seam; guide sleeve is connected with cylinder barrel by screw thread, and piston to be connected with piston rod by screw thread and to be placed in confined space that cylinder bottom, cylinder barrel and guide sleeve form.
Working principle: when dynamical element is to oil cylinder rodless cavity fuel feeding, hydraulic oil promotes piston and does rod motion, promote the hydraulic lock that hydraulic control spool backs down side simultaneously, the hydraulic lock that hydraulic oil in rod chamber is opened by this side is discharged, when dynamical element fuel cut-off, steel ball resets by the Returnning spring in hydraulic lock, and the hydraulic oil of rod chamber is not then discharged by the hydraulic lock of this side, and then is pinned by piston rod; When dynamical element is to cylinder rod chamber fuel feeding, hydraulic oil promotes piston and does back bar motion, promote the one-way valve that hydraulic control spool backs down opposite side simultaneously, the hydraulic lock that hydraulic oil in rodless cavity is opened by this side is discharged, when dynamical element fuel cut-off, steel ball resets by the Returnning spring in hydraulic lock, and the hydraulic oil of rodless cavity is not then discharged by the hydraulic lock of this side, and then is pinned by piston rod.
As mentioned above, coal winning machine adjust high cylinder of the present utility model, has following beneficial effect:
Oil circuit is integrated on cylinder bottom by this Split type hydraulic lock, adopts split type structure, has abandoned the all-in-one-piece structure of original hydraulic lock, on the basis of assurance function again, significantly simplify the structure, reduce volume, simplify processing, manufacture cost obtains and significantly reduces.The hydraulic lock of adjust high cylinder belongs to the standing renewal part of maintenance, when all-in-one-piece hydraulic lock breaks down, need the hydraulic lock that integral replacing is new, maintenance cost is high, and the hydraulic lock one side manufacture cost of split-type structural is far below the hydraulic lock of monolithic construction, when the hydraulic lock of split-type structural breaks down on the other hand, only need change the hydraulic lock of fault, do not have out of order hydraulic lock then can continue to use, easy to maintenance, service cycle shortens, improves effect, reduces cost of upkeep, and then the maintenance expenses in later stage have also been obtained and significantly reduces.
