Description
Technical field
The application belongs to railroad maintenance apparatus field, specifically, more particularly to a kind of tamping pickaxe mechanical lube system
System.
Background technique
The railway ballast tamping pickaxe that railway routine servicing uses at present, if all will increase railway maintenance using import
Cost in journey.And the factors such as production and processing level are limited to, often there is impact system lubrication in domestic some tamping pickaxes
Insufficient problem.Such as the tamping pickaxe having just will appear impact inability, lubrication after using a period of time (10~20 hours)
The problems such as oil sealing serious wear, shortens the service life of tamping pickaxe, directly affects the daily maintenance work of railway, and increase
The cost of railway routine servicing operation.
Summary of the invention
A kind of mechanical lubricating system for being designed to provide tamping pickaxe of the application, is able to solve existing tamping pickaxe and deposits
Impact system lack of lubrication the problem of.
In order to achieve the above objectives, the application is achieved through the following technical solutions:
The mechanical lubricating system of tamping pickaxe described herein, including outer cylinder, in the upper space of outer barrel
The impact piston group of up and down motion is installed, stamp stem and the stamp stem with stamp stem cooperation are installed in the lower space of outer barrel
Set, the outside of the outer cylinder are additionally provided with toroidal cavity, and toroidal cavity passes through in upper hydraulic fluid port, lower hydraulic fluid port and the outer cylinder on outer cylinder
Cavity connection；The inner chamber body of the outer cylinder is separated into upper plenum, lower cavity by stamp stem, and lower cavity is located at stamp stem and stamp stem covers it
Between.
Further speaking, O-ring sealing group is installed between stamp stem described herein and the inner surface of outer cylinder.
Further speaking, O-ring seal is installed, stamp stem stretches out stamp stem between stamp stem described herein set and outer cylinder
Dust ring is installed at the position of set.
Compared with prior art, the beneficial effect of the application is:
The application realizes the profit to its internal impact system by improving to the lubricating loop system in tamping pickaxe
It is sliding, avoid occurring the problems such as powerless impact, lubrication oil seal serious wear in use process, and then extend tamping pickaxe uses the longevity
Life reduces the cost of railway ballast upkeep operation.

The restriction of range or technical solution, purpose only more fully understand technology described herein for convenience of those skilled in the art
Scheme.
Embodiment 1: a kind of mechanical lubricating system of tamping pickaxe comprising outer cylinder 3 is installed in the inner upper of outer cylinder 3
There is the impact piston group 2 that can be moved up and down therewith, the lower section inside outer cylinder 3 is equipped with stamp stem set 6, installs on stamp stem set 6
There is matched stamp stem 5；The outside of the outer cylinder 3 is also machined with toroidal cavity A, and toroidal cavity A passes through upper on outer cylinder 3
The inner cavity of hydraulic fluid port 9, lower hydraulic fluid port 11 and outer cylinder 3 penetrates through, and the inner cavity of outer cylinder 3 is separated into upper plenum B and lower cavity C by stamp stem 5,
O-ring sealing group 4 is installed on stamp stem 5 between upper plenum B and lower cavity C.Pacify in stamp stem set 6 and the contact position of outer cylinder 3
Equipped with O-ring 7, the exit of stamp stem 5 is equipped with dust ring 8 on stamp stem set 6.
On the basis of the above embodiments, toroidal cavity A described herein is an annular chamber on 3 shell of outer cylinder
Body, and upper plenum B is then impact piston group 2 and the cavity that stamp stem 5 is formed in the inner cavity of outer cylinder 3, lower cavity C is stamp stem
5 and 6 cavitys being formed in outer cylinder 3 of stamp stem set.
As shown in Figure 1, the impact piston group 2 in the application is to provide it by power source 1 to do fortune up and down in outer cylinder 3
Dynamic power, to realize that stamp stem 5 equally moves up and down in cylinder 3 outside under the support of stamp stem set 6.When impact piston group
2 when moving upwards, and negative pressure is formed at upper plenum B, and lubricating oil is entered in upper plenum B from toroidal cavity A by upper oil hole 9；When
When impact piston group 2 moves downward, the upper plenum B volume between impact piston group 2 and stamp stem 5 rapidly reduces, in upper plenum B
Pressure becomes larger, and the lubricating oil on 3 inner wall of outer cylinder is forced to enter in lower cavity C from from the position of O-ring sealing group 4.It enters
Lubricating oil in lower cavity C is entered in toroidal cavity A by the lower hydraulic fluid port on outer cylinder 3, finally forms one in the inside of outer cylinder 3
A complete lubricating loop system.
