Abstract
The utility model relates to a cylinder body assembly device in large -scale quartering hammer, including well cylinder body, oil blanket fixer, piston and bearing structure, bearing structure installs in oil blanket fixer below, the inside annular table shoulder that is equipped with installation bearing structure of well cylinder body. Cylinder body assembly device compact structure in being somebody's turn to do prevents the wearing and tearing of piston and cylinder body, high, the long service life of work efficiency.
Description
Technical field
This utility model is related to a kind of middle cylinder body assembly apparatus, cylinder assembly dress in more particularly, to a kind of large-scale quartering hammer
Put, belong to Hydraulic Field.
Background technology
In old-fashioned in the past large-scale quartering hammer, cylinder assembly top only has oil sealing holder, does not have single piston to support protection
Structure.When quartering hammer misoperation or quartering hammer lead to oil sealing serious wear because working long hours, on oil sealing holder
Oil sealing can decline to the constraint enabling capabilities of quartering hammer internal piston, cause piston in the inclination of quartering hammer cylinder interior, lead to
Piston is not coaxial with inner chamber of cylinder block.When high speed piston moves, between piston, cylinder body and oil sealing holder cavity wall, lubricating oil film is easy
Rupture, the directly contact of piston, cylinder body and oil sealing holder inner chamber, easily cause cylinder body, abrasion pulled by piston, oil sealing holder,
In turn result in the leakage of quartering hammer internal hydraulic pressure oil, reduce quartering hammer work efficiency.
Utility model content
This utility model is directed to deficiency, provides a kind of compact conformation, prevents piston and cylinder body abrasion, high working efficiency, makes
With cylinder body assembly apparatus in the large-scale quartering hammer of life-span length.
The technical scheme that this utility model solves above-mentioned technical problem is as follows: cylinder body structural assembly dress in a kind of quartering hammer
Put, including in cylinder body, oil sealing holder, piston, also include supporting construction, described supporting construction includes inner ring, pars intermedia and outer
Circle, described middle cylinder interior is provided with the shoulder installing supporting construction.
On the basis of technique scheme, this utility model can also do following improvement.
Further, the inner ring of described supporting construction and outer ring adopt alloyed copper, and the pars intermedia of described supporting construction is using conjunction
Jin Gang.
Further, described supporting construction is arranged on the lower section of oil sealing holder.
Further, the internal diameter of described supporting construction is less than the internal diameter of oil sealing holder.
The beneficial effects of the utility model are: employ piston support structure, ensure that the axial direction to piston for the holder
Restraining forceies, prevent piston and cylinder body abrasion, long service life, high working efficiency, compact conformation.
Brief description
Fig. 1 is oil sealing holder and supporting construction schematic diagram in this utility model；
Fig. 2 is this utility model general assembly drawing；
The middle cylinder body assembly apparatus figure of Fig. 3 prior art；
In the accompanying drawings, the list of designations represented by each label is as follows: 1, oil sealing holder, and 2, supporting construction, 2-a,
Supporting construction inner ring, 2-b, supporting construction pars intermedia, 2-c, supporting construction outer ring, 3, piston, 4, middle cylinder body, 5, oil sealing.
Specific embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example is served only for explaining this practicality
New, it is not intended to limit scope of the present utility model.
As shown in figure 3, the middle cylinder body assembly apparatus of the large-scale quartering hammer for prior art, there is no piston support structure, easily
Lead to oil sealing that abrasion occurs, and then lead to piston crooked vertically, accelerated wear test.
As shown in Figure 1, 2, cylinder body assembly apparatus in a kind of quartering hammer, including in cylinder body 4, oil sealing holder 1, piston 3, also
Including supporting construction 2, described supporting construction 2 includes inner ring 2-a, middle part 2-b and outer ring 2-c, is provided with peace inside described middle cylinder body 4
Fill the shoulder of described supporting construction 2, described supporting construction inner ring 2-a and outer ring 2-c adopts alloyed copper, in the middle of described supporting construction
Portion 2-b adopts steel alloy；Described supporting construction 2 is arranged on the lower section of oil sealing holder 1；The inner ring 2-a ratio of described supporting construction 2
The inner ring of oil sealing holder 1 is little.
Described oil sealing holder 1 height reduces, and increased described supporting construction 2, leads to described piston 3 and described middle cylinder body
4 length accordingly increases.When piston high-speed motion run-off the straight about 3, contact with supporting construction 2 first, rather than and oil
The lumen contact of envelope holder 1, prevents piston 3 and middle cylinder body 4 from wearing and tearing.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all in this practicality
Within new spirit and principle, any modification, equivalent substitution and improvement made etc., should be included in guarantor of the present utility model
Within the scope of shield.
