Description
Technical field
The invention belongs to rolling stock manufacture, maintenance, machine-building etc., are used for railway freight-car central sill more particularly, to a kind of
The adjusting fixture of opening and adjusting method.
Background technology
In railway freight-car operation, often occur to rise outside central sill, the phenomenon that lower aerofoil is upwarped, as shown in figure 1, A in generation
Beam rises outward, lower aerofoil occurs at B and upwarps, and the maintenance of above-mentioned failure need to typically rely on Large Hydraulic Equipment (loaded vehicle underframe adjusting tire)
Auxiliary.In the environment of main equipment is lacked, it is difficult to overhaul this two kinds of failures.
Existing service technique relies primarily on loaded vehicle underframe adjusting tire, by place of rising outside the hydraulic thrust crown firmly central sill, applies
Pressure rises to outside central sill and is contracted to standard size, central sill lower aerofoil upwarp be usually used cutting torch, hammer be adjusted.
Requirement of the prior art to equipment, place is higher, it is desirable to have power system, the support of hydraulic system.In regulation
When lower flange of girder face upwarps, manually beat and be often difficult to control to regulated quantity, cause degree of regulation not good.Meanwhile, when vehicle to be repaired only
Occur outer rise or upwarp when waiting single failure, also need for vehicle to import adjusting tire, cause cost more time and resource.
Content of the invention
The present invention mainly solves the technical problem existing for prior art；Can be by central sill open-mouth ruler there is provided a kind of
Very little, the lower aerofoil amount of upwarping is adjusted to the requirement for meeting railway freight-car repair in shop code；Requirement of the central sill maintenance to place is reduced, is realized
The flexible maintenance of central sill, while the use of maintenance that realizes rising outside central sill under the extreme condition for lacking electric power, main equipment, upwarp
Adjusting fixture and adjusting method in railway freight-car central sill opening.
The above-mentioned technical problem of the present invention is mainly addressed by following technical proposals：
A kind of adjusting fixture for railway freight-car central sill opening, it is characterised in that including two F being symmetrical set
Shape claw, two coupling assemblies and a double threaded screw；Fix a stator with hole clipping in the F shapes claw bottom；Institute

The piece that is connected in hole, the connecting hole is identical with the aperture of hole clipping and can pass through semi-finished round pin and pin by F shapes claw and connection
Component is coupled together；Double threaded screw can sequentially pass through two nuts and by rotate double threaded screw adjust two F shapes claws it
Between distance.
In a kind of above-mentioned adjusting fixture for railway freight-car central sill opening, a screw rod in the middle part of double threaded screw, is provided with
Hole, is rotated after convenient insertion crowbar.
A kind of method of taking off of the adjusting fixture using for railway freight-car central sill opening, it is characterised in that including two
Adjusting step is selected, i.e.,：Rise and adjust central sill lower aerofoil outside adjustment central sill and upwarp, method is as follows：
Select adjusting step one：When needing to rise outside regulation adjustment central sill, claw is arranged on outside central sill place of rising, it is ensured that card
Button covers lower aerofoil length and is not less than 50mm, and guarantees that installation is firm；Measurement two claws pitch-row, by two nuts respectively from
Double threaded screw two ends penetrate, and adjust the spacing of two nuts so as to equal with the pitch-row of claw；Double threaded screw is lifted, until
Connecting hole is overlapped with hole clipping, is inserted into semi-finished round pin in hole, mounting gasket and pin on semi-finished round pin, at lead screw hole inserts sled
Rod, using crest line at angle of rising outside cutting torch heating central sill, turn clockwise double threaded screw, until central sill outside of belly spacing is tightened to standard
Size, after the completion of regulation, treats central sill heating position cooling, removes central sill opening adjusting fixture.
Select adjusting step 2：When needing regulation central sill lower aerofoil to upwarp, claw is arranged on outside central sill place of rising, it is ensured that
Buckle covers lower aerofoil length and is not less than 50mm, and guarantees that installation is firm；The pitch-row of two claws of measurement, two nuts are distinguished
Penetrate from double threaded screw two ends, and adjust the spacing of two nuts so as to be equal with the pitch-row of claw；Double threaded screw is lifted, directly
Overlapping with hole clipping to connecting hole, semi-finished round pin being inserted in hole, mounting gasket and pin on semi-finished round pin are inserted at lead screw hole
Crowbar, using crest line at cutting torch heating central sill lower aerofoil upper uplifting angle, turn clockwise double threaded screw, because adopting between claw and screw rod
Connected with round pin, during claw shrinks, while passively rotating, the lower aerofoil for upwarping is turned back to plane, in treating
Soffit of girder interplanar distance is tightened to standard size, and regulation is completed, and after the completion of regulation, treats central sill heating position cooling, removes central sill opening
Adjusting fixture.
Therefore, the invention has the advantages that：1st, the portion of large-scale loaded vehicle central sill adjusting tire is realized by using small instruments and tools
Divide function, while reducing dependence of the central sill adjusting operation to electric power, hydraulic system and place, by simple maintenance mode, adjust
Rise outside section central sill, lower aerofoil upwarps the standard size specified to railway freight-car repair in shop code；2nd, increase the motility of central sill maintenance,
And under the extreme condition for lacking main equipment (in railway line), realize the purpose of the outer trouble shooting such as rise, upwarp.
