Abstract
The utility model discloses an upright column lubricating device. An upright column comprises a cylinder tube, a guide sleeve is disposed between an upper opening of the cylinder tube and an inner cylinder wall or a movable column, and the outer end of the guide sleeve is provided with an annular oil storage device which is responsible for lubricating the inner cylinder wall or the movable column recycled from the outside. A large quantity of lubricating media can be injected, the lubricating effect is good, and the service life is long.
Description
Technical field
The utility model relates to a kind of coal-mine hydraulic support pillar, relates in particular to a kind of column lubricating fitting.
Background technique
Coal-mine hydraulic support pillar finds in real work, and Sealing producer no leakage when guaranteeing oil hydraulic cylinder product export has strengthened the decrement of Sealing; So just caused Sealing intermediate portion region lubricated, made its part in dry grinding state, and column is to regain from ambient air in the time regaining, really there is no lubricating fitting, be generally the first leakage of sealing on guide sleeve.
Prior art one:
On guide sleeve, process the method for oil hole, with lubricating cup to the butter of annotating in hole.Concrete grammar is: bore a blind hole in guide sleeve exterior edge face, and one section of screw thread of merit outside blind hole, then from radially boring another hole, drill through guide sleeve inner side, and the connection crossing with hole before of this hole, after guide sleeve is assembled on column so always, on end-face hole, load onto lubricating cup, just can oiling.
Advantage: easy processing, processing cost is low, saves process time.
Shortcoming: because the poor fluidity of butter, and dust ring is pressed in middle cylinder or the pressure that coordinates on post of living is very large, pass through and discharge to such an extent as to be difficult to air, oil hole is now only just also quite a blind hole, so butter be difficult to inject and by Bas Discharged, be equal to and in oil hole, only have a bit of butter and compressed air, the method for oil injecting lubricating does not play due effect.
Comparison: can adopt, but must be before installation just butter be injected, once butter is finished, or stop flowing, column also will be in disliking summary ambient condition.
Prior art two:
Adopt on the basis of method before, increase an oil hole at oil hole offside, object is that the butter that in two holes, air can be squeezed into is replaced, and lubricant medium is worked in the time of product work again, this processing method and prior art one are similar, have just formed symmetrical oil hole.
Advantage: can allow butter fill all grooves and hole by oil hole, by most of Bas Discharged, can realize lubricated effect with butter.
Shortcoming: need the oil holes that bore more, improved cost, if used for a long time, also take an examination and examine regular filling butter, improved maintenance cost.
Comparison: using effect is relatively good, but need to carry out the maintenance work in later stage.
Model utility content
The purpose of this utility model is to provide the column lubricating fitting of a kind of high lubricating effect, long service life.
The purpose of this utility model is achieved through the following technical solutions:
Column lubricating fitting of the present utility model, described column comprises earthen pipe, between the suitable for reading and interior casing wall of described earthen pipe or post alive, is provided with guide sleeve, comprises annular Fuel Tanking Unit, described Fuel Tanking Unit is loaded on the outer end of described guide sleeve.
The technological scheme being provided by above-mentioned the utility model can be found out, the column lubricating fitting that the utility model embodiment provides, described column comprises earthen pipe, owing to being provided with annular Fuel Tanking Unit between guide sleeve and interior casing wall or post alive, be responsible for the lubricated interior casing wall of regaining from the external world or the post of living, can inject a large amount of lubricant mediums, high lubricating effect, long service life.
Accompanying drawing explanation
The structural representation of the column lubricating fitting that Fig. 1 provides for the utility model embodiment.
In figure: 1-earthen pipe, 2-guide sleeve, the lubricant mediums such as 3-lubricant oil or emulsified liquid stoste, 4-Fuel Tanking Unit, the part (comprise the multiple fixing devices such as screw, omit in figure) of other fixing Fuel Tanking Unit of 5-.
Embodiment
To be described in further detail the utility model embodiment below.
Column lubricating fitting of the present utility model, its preferably embodiment be:
Described column comprises earthen pipe, between the suitable for reading and interior casing wall of described earthen pipe or post alive, is provided with guide sleeve, comprises annular Fuel Tanking Unit, and described Fuel Tanking Unit is loaded on the outer end of described guide sleeve, is responsible for the lubricated interior casing wall of regaining from the external world or the post of living.
Described Fuel Tanking Unit is towards described interior casing wall or the side opening of post of living, and is provided with seal arrangement between the edge of opening and described interior casing wall or work post.
Described Fuel Tanking Unit is fixed on described guide sleeve.
Column lubricating fitting of the present utility model, on original column, increase a fuel reserve tank, fuel reserve tank profile is ring-shape accessory, interior porose and groove, install after Sealing, be fixed on guide sleeve, when its work, inside is filled with lubricant medium, and two ends are kept at lubricant medium in fuel reserve tank by Sealing, mailbox outer surface has pouring orifice, fill and have special stifled hydraulic fluid port is sealed after oil, avoid dust etc. to fall into hydraulic fluid port, pollution lubricating medium; Finally, by fixing devices such as screw or bolt, jigs, this fuel tank is fixed on guide sleeve, because fixing device and seal arrangement are varied, so only draw schematic diagram sketch, simplified schematic diagram is as follows:
Use the method for this scheme, can inject a large amount of lubricant mediums, although in the time of work, can consume lubricant medium by the reason such as loss, leakage, but the space in fuel reserve tank relatively before device is larger, can there be a large amount of lubricant mediums, in use can meet long use, reduce the number of times of safeguarding, promote the efficiency of machine work, lengthen the working life of product, extended the time that product carries out large repairs to needs from work, for product high-yield and high-efficiency has been established technical foundation.
As shown in Figure 1, be the principle sketch of column lubricating fitting, as by this principle distressed structure and shape, change fuel reserve tank means of fixation etc., as long as relate to increase Fuel Tanking Unit, be used for alleviating the device of sealing part abrasion, all in this creation protection domain.
The above; it is only preferably embodiment of the utility model; but protection domain of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model disclose technical scope in; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
