Abstract
The present invention relates to a kind of track crane trolley span correction process, its step is as follows: doorframe top, both sides pull bar operates on process, and dolly rests in side, track crane non-electrical room, utilizes door machine or truck crane lifting trolley non-drag chain side to leave girder doorframe；Mounting process support in the middle of girder doorframe, and utilize jack adjustment girder doorframe to target distance, both ends utilize chain block to coordinate jack to tighten up to inner side；Repetition measurement trolley track related data；It is protected from scalding to correction position bracket cable parcel；Carrying out firer's correction on crossbeam doorframe, it is desirable to temperature must not exceed 600 DEG C, same position firer correction must not exceed 3 times, the parcel slow cooling of orbit correction position；Firer has corrected rear repetition measurement dolly linearity and gauge.It is an advantage of the current invention that: in the case of track crane trolley track completes, can readjust the spacing of track, and the linearity of guarantee track, step is simple, and the trolley track after processing can be fully achieved requirement.
Description
Technical field
The present invention relates to a kind of track crane field, particularly to a kind of track crane trolley span correction process.
Background technology
Track crane is the one of hoisting machinery, including being symmetricly set on the supporting leg doorframe of both sides and being horizontally set with at two supporting leg doors
Crossbeam doorframe on frame, dolly is slidably arranged on crossbeam doorframe, due to the deviation in the course of processing, little track on crossbeam doorframe
Away from producing bigger deviation, but trolley track is machined to be completed, and to be adjusted trolley span, needs to consider each side
Face factor, difficulty is bigger.
Summary 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.
For solving above-mentioned technical problem, the technical scheme is that a kind of track crane trolley span correction process, its wound
New point is: its step is as follows:
(1) doorframe top, both sides pull bar is operated on process, by means of positive trolley span；
(2) dolly rests in side, track crane non-electrical room, utilizes door machine or truck crane lifting trolley non-drag chain side to leave girder door
Frame；
(3) mounting process support in the middle of girder doorframe, and utilize jack to adjust girder doorframe to target distance, both ends utilization
Chain block coordinates jack to tighten up to inner side；
(4) qualified rear repetition measurement trolley track related data is adjusted；
(5) it is protected from scalding to correction position bracket cable parcel；
(6) carrying out firer's correction on crossbeam doorframe, it is desirable to temperature must not exceed 600 DEG C, same position firer must not correct and surpassed
Cross 3 times, the parcel slow cooling of orbit correction position；
(7) firer has corrected rear repetition measurement dolly linearity and gauge.
Further, in described step (2), when crossbeam doorframe left under order by dolly, its non-drag chain side wheel with track space is
10~20mm。
Further, in described step (3), dividing plate in the necessary alignment box body in jack jacking position.
It is an advantage of the current invention that: the spacing of track in the case of track crane trolley track completes, can be readjusted,
And the linearity of guarantee track, step is simple, and the trolley track after processing can be fully achieved requirement.
Detailed description of the invention
Girder is time general assembly puts in place, if the gauge deviation of dolly is relatively big, need to adjust the size of gauge therefore require two side doors
Process operated on by arch pull bar, by means of positive trolley span.But under this state, dolly correction state is undesirable, and rail linearity degree is relatively
Difference, carries out firer's correction process according to this state technological requirement to main beam structure；
(1) dolly is rested in side, non-electrical room, treat that firer's timing utilizes door machine or truck crane lifting trolley non-drag chain side to make
Wheel and track space (10 ~ 20mm)；
(2) mounting process support in the middle of girder, and utilize jack to adjust trolley span target range, it is desirable to jacking position is necessary
Dividing plate in alignment box body, both ends utilize chain block tighten up to inner side or pull open laterally；
(3) qualified rear repetition measurement trolley track related data is adjusted；
(4) it is protected from scalding to correction position bracket cable parcel before firer corrects；
(5) orbital position between crossbeam doorframe carries out firer's correction, it is desirable to temperature must not exceed 600 DEG C, same position firer school
Just must not exceed 3 times, the parcel slow cooling of orbit correction position；
(6) firer has corrected rear repetition measurement dolly linearity and gauge.
If data qualifier after above-mentioned steps, the overproof 1mm in non-drag chain siding track linearity local, if without level on track crane
Take turns therefore can not process.
As a example by the track crane that trolley span is 6900 ± 9mm, whole hang completion after, carry out heavy duty experiment, arrive along electrical side
Non-electrical siding track hangs and arranges six monitoring points, track crane gauge Details as Follows table:
Detecting data in upper table and exceeded deviation requirement, need to be adjusted trolley span, according to above-mentioned technique, two lateral bracing struts are adjusted
After whole, trolley track arranges a test point, its data such as following table:
Finding out from upper table, correction state is undesirable, need to correct crossbeam doorframe firer；Firer has corrected one group of dolly of rear repetition measurement
Gauge, such as following table:
Data are all in tolerance, it is believed that gauge is adjusted in place.
Ultimate principle and the principal character of the present invention have more than been shown and described.Skilled person will appreciate that of the industry,
The present invention is not restricted to the described embodiments, the principle that the present invention is simply described described in above-described embodiment and description,
Without departing from the spirit and scope, the present invention also has various changes and modifications, and these changes and improvements all fall
Enter in scope of the claimed invention.Claimed scope is defined by appending claims and equivalent thereof.
