Description
Technical field
The invention belongs to the technical field of railway casting, in particular to a kind of railway service sleeve.
Background technique
Important component one of of the fastener system as track structure, not only laying quantity is big, with high content of technology, and develops
Period is long, needs to carry out it to continue research and development and improves.Bolt used in fastener system passes through the spiral shell of bolt and service sleeve
Frictional force between line contact surface plays the purpose of fastening spring.
Although indices all meet the requirements during installation, during long-term military service, repeatedly due to wheel rail force
Effect so that occur gap between bolt and the thread contact face of service sleeve, the fine particles such as dust, sandstone will along
Gap enters inside service sleeve.
And being splashed into order to avoid mud, the lower end of service sleeve is mostly using sealing design, therefore dust, the sandstone entered
It can not be discharged, seriously affect the use of fastener system.
More seriously, bolt can be removed when the fastener system maintenance of railway, even if bolt and service sleeve
Thread contact face between do not occur gap, when extracting bolt, the sewage that is gathered between bolt and service sleeve and tiny
Drift sand can equally enter inside service sleeve, so that bolt can not be installed again.
Summary of the invention
The object of the present invention is to provide a kind of railway service sleeves, allow and arrange into the sundries inside service sleeve
Out, while being splashed into for bottom mud is avoided.
The object of the present invention is achieved like this: a kind of railway service sleeve, including casing main body, described sleeve pipe main body
Inner wall is provided with the internal screw thread with screw spike cooperation, and outer wall is provided with the external screw thread with concrete sleeper cooperation, described sleeve pipe
The lower end of main body is connected with impurity elimination property management, is centrally located on the side wall of impurity elimination property management there are two opposite mounting hole, in mounting hole
Rotation is provided with rotational pin, and the runner with several wheel blades is fixed on rotational pin, wheel blade and impurity elimination property management when runner rotates
Inner wall contact, and runner can rotate automatically.
Preferably, above-mentioned impurity elimination property management is fillet cylindricality.
Preferably, the inner wall of above-mentioned impurity elimination property management is provided with spherical arc, and the wheel blade is semicircle, and rotational trajectory is
By the ball of spherical arc.
Preferably, at least two panels wheel blade is contacted with spherical arc always when above-mentioned runner rotates, thus to impurity elimination property management
It is sealed.
Preferably, above-mentioned wheel blade is provided with 6-8 piece, is located on runner in uniform week.
Preferably, the radial center face of above-mentioned wheel blade and rotational pin are tangent, and wheel blade is gradually thinning from inside to outside.
Annular groove is provided on the lower end inner wall of above-mentioned casing main body, the diameter of the annular groove is greater than impurity elimination property management
Opening diameter, less than the diameter of spherical arc.
The upper end inner wall of above-mentioned casing main body is tapered slope, and diameter is gradually increased from bottom to top.
Compared to the prior art the present invention, has the following beneficial effects:
1, the present invention is by the runner that can be freely rotated of setting, when the sundries such as fine sand, sewage are fallen on wheel blade from top,
When running up to a certain amount of, the gravity of sundries is greater than the resistance of wheel blade rotation, and wheel blade will rotate, will accumulate on wheel blade
Sundries discharge.
2, wheel blade of the invention always seals impurity elimination property management, avoid the mud of bottom from bottom to top be splashed into sundries
Inside pipe.
Detailed description of the invention
Fig. 1 is main view of the invention.
Fig. 2 is cross-sectional view of the invention.
Fig. 3 is perspective view of the invention.
Appended drawing reference: 1, casing main body；2, internal screw thread；3, external screw thread；4, impurity elimination property management；5, rotational pin；6, wheel blade；7, turn
Wheel；8, spherical arc；9, annular groove；10, tapered slope.
Specific embodiment
With specific embodiment, the invention will be further described with reference to the accompanying drawing, referring to Fig. 1-3:
A kind of railway service sleeve, including casing main body 1, the inner wall of described sleeve pipe main body 1 is provided with matches with screw spike
The internal screw thread 2 of conjunction, outer wall are provided with the external screw thread 3 with concrete sleeper cooperation, and the lower end of described sleeve pipe main body 1 is connected with impurity elimination
Property management 4 is centrally located on the side wall of impurity elimination property management 4 there are two opposite mounting hole, and rotation is provided with rotational pin 5 in mounting hole,
The runner 7 with several wheel blades 6 is fixed on rotational pin 5, wheel blade 6 is contacted with the inner wall of impurity elimination property management 4 when runner 7 rotates, and
Runner 7 can rotate automatically, certainly, due to the influence of machining accuracy, also allow to deposit between wheel blade 6 and the inner wall of impurity elimination property management 4
In minim gap.
Since, there are gap, the fine particles such as dust, sandstone will be suitable between bolt and the thread contact face of service sleeve
Gap enter inside service sleeve；Alternatively, when being removed to bolt, the sewage that is gathered between bolt and service sleeve and
Tiny drift sand can equally enter inside service sleeve.When the gravity of these sundries is greater than the resistance that wheel blade 6 rotates, runner 7 is just
It can rotate, service sleeve is discharged along the runner 7 of rotation in sundries.
Comparative diagram 3, above-mentioned impurity elimination property management 4 are fillet cylindricality.
