Abstract
The present invention relates to a kind of track crane trolley span correction process, its step are as follows：Processing is operated on to both sides doorframe top pull bar, dolly rests in track crane non-electrical room side, and girder doorframe is left using door machine or the non-drag chain side of truck crane lifting trolley；Mounting process supports among girder doorframe, and adjusts girder doorframe to target spacing, both ends using jack and coordinate jack to be tightened up to inner side using chain block；Repetition measurement trolley track related data；Correction position bracket cable parcel is protected from scalding；Firework correction is carried out on crossbeam doorframe, it is desirable to which temperature must not exceed 600 DEG C, and same position firework correction must not exceed 3 times, the parcel slow cooling of orbit correction position；Repetition measurement dolly linearity and gauge after the completion of firework correction.The advantage of the invention is that：The spacing of track in the case where track crane trolley track has completed, can be readjusted, and ensures the linearity of track, step is simple, and requirement can be fully achieved in the trolley track after processing.
Description
Technical field
The present invention relates to a kind of track crane field, more particularly to a kind of track crane trolley span correction process.
Background technology
Track crane is one kind of hoisting machinery, including is symmetricly set on the supporting leg doorframe of both sides and is horizontally set with two supporting leg doors
Crossbeam doorframe on frame, dolly are slidably arranged on crossbeam doorframe, due to the deviation in process, small track on crossbeam doorframe
Away from can produce larger deviation, but the machined completion of trolley track, to be adjusted to trolley span, it is necessary to consider each side
Face factor, difficulty are larger.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of track crane trolley span correction process.
In order to solve the above technical problems, the technical scheme is that：A kind of track crane trolley span correction process, it is created
New point is：Its step is as follows：
（1）Processing is operated on to both sides doorframe top pull bar, by means of positive trolley span；
（2）Dolly rests in track crane non-electrical room side, and master is left using door machine or the non-drag chain side of truck crane lifting trolley
Liangmen frame；
（3）Mounting process supports among girder doorframe, and adjusts girder doorframe to target spacing, both ends using jack
Jack is coordinated to be tightened up to inner side using chain block；
（4）Adjust qualified rear repetition measurement trolley track related data；
（5）Correction position bracket cable parcel is protected from scalding；
（6）Firework correction is carried out on crossbeam doorframe, it is desirable to which temperature must not exceed 600 DEG C, and same position firework correction is not
Must be more than 3 times, the parcel slow cooling of orbit correction position；
（7）Repetition measurement dolly linearity and gauge after the completion of firework correction.
Further, the step（2）In, during dolly distancing crossbeam doorframe, its non-drag chain side wheel and interorbital away from for
10~20mm。
Further, the step（3）In, dividing plate in the necessary alignment box body in jack jacking position.
The advantage of the invention is that：In the case where track crane trolley track has completed, the spacing of track can be readjusted,
And ensureing the linearity of track, step is simple, and requirement can be fully achieved in the trolley track after processing.
Embodiment
Girder general assembly in place when, if the gauge deviation of dolly is larger, need to adjust gauge size thus require to two side doors
Arch pull bar operates on processing, by means of positive trolley span.But under this state dolly correction state it is undesirable, rail linearity degree compared with
Difference, firework correction processing is carried out to main beam structure according to this state technological requirement；
（1）Dolly is rested in into non-electrical room side, door machine or truck crane lifting trolley non-drag chain are utilized when firework correction
Side make wheel and interorbital away from（10~20mm）；
（2）Mounting process supports among girder, and utilizes jack adjustment trolley span target range, it is desirable to jacks position
Dividing plate in necessary alignment box body, both ends are tightened up to inner side using chain block or pulled open laterally；
（3）Adjust qualified rear repetition measurement trolley track related data；
（4）Correction position bracket cable parcel is protected from scalding before firework correction；
（5）Orbital position between crossbeam doorframe carries out firework correction, it is desirable to which temperature must not exceed 600 DEG C, same position fire
Work correction must not exceed 3 times, the parcel slow cooling of orbit correction position；
（6）Repetition measurement dolly linearity and gauge after the completion of firework correction.
If the data qualifier after above-mentioned steps, the local overproof 1mm of non-drag chain siding track linearity, if without level on track crane
Take turns therefore can not process.
By trolley span be 6900 ± 9mm track crane exemplified by, it is whole hang completion after, carry out heavily loaded experiment, arrived along electrical side
Non-electrical siding track, which is hung, sets six monitoring points, track crane gauge Details as Follows table：
Data are detected in upper table and exceed deviation requirement, trolley span need to be adjusted, according to above-mentioned technique, the adjustment of two lateral bracing struts
Afterwards, a test point, its data such as following table are set on trolley track：
As can be seen from the above table, correction state is undesirable, need to be to crossbeam doorframe firework correction；One group of dolly of repetition measurement after the completion of firework correction
Gauge, such as following table：
Data are in tolerance, it is believed that gauge has been adjusted in place.
The general principle and principal character of the present invention has been shown and described above.It should be understood by those skilled in the art that
The present invention is not limited to the above embodiments, merely illustrating the principles of the invention described in above-described embodiment and specification,
Without departing from the spirit and scope, various changes and modifications of the present invention are possible, and these changes and improvements all fall
Enter in scope of the claimed invention.The scope of the present invention is defined by the appended claims and its equivalents.
Claims (3)
