Abstract
The invention relates to a method for quickly replacing a crane beam without using a hoist for construction. The method comprises the following steps of: 1) arranging a temporary platform on a crane, hoisting a new crane beam to the temporary platform for fixing at a hoist position in a workshop, and horizontally transporting the new crane beam to a position over an old crane beam which is needed to be replaced by running the crane; 2) arranging a hanging point and a first temporary tripod on a column at two ends of the old crane beam, lifting the new crane beam and moving the new crane beam away from the crane by using a chain block, putting the new crane beam on the first temporary tripod for fixing, and removing the hanging point of the lower end of the chain block and the new crane beam; 3) removing the old crane beam and descending the old crane beam to the lower side of a mounting position of the new crane beam by using the chain block, and fixing the old crane beam on a second temporary tripod of the column; 4) arranging the new crane beam in place by using the chain block; and 5) after a rail is recovered, hoisting the old crane beam by using the crane. By the method, operation difficulty is reduced, and the construction progress is accelerated; and the whole method is simple, practical, safe and reliable.
Description
Technical field
The present invention relates to a kind of construction work method, relate in particular to a kind of quick-replaceable crane beam method that can not use crane construction.
Background technology
In the maintenance engineering of workshop; often can run into and only change local crane beam; and this crane beam below is production equipment, can not remove or be shifted, the roofing of top can not be removed because producing; cause crane directly to lift; it has caused changing crane beam in the short time, on producing the impact that has caused very large impact, and as only adopted manual operation; waste time and energy, have again very large potential safety hazard.
Summary of the invention
The object of the present invention is to provide a kind of quick-replaceable crane beam method that can not use crane construction, its practicality simple to operate, safe and efficient.
The technical solution used in the present invention:
A kind of quick-replaceable crane beam method that can not use crane construction, it comprises the steps 1) first in driving, temporary platform is set, in workshop, can place crane place, new crane beam is lifted in temporary platform and is fixed, utilize driving walking new crane beam horizontal transport to be arrived directly over the old crane beam that need to change; 2) hanging point and the first interim tripod are set on the pillar of old crane beam two ends, utilize jack that new crane beam is mentioned and remove driving, newer crane beam is placed on the first interim tripod and is fixed, extract the hanging point of jack lower end and new crane beam; 3) then utilize jack that old crane beam is removed and dropped to the below that new crane beam is installed, and old crane beam is fixed on the second interim tripod of pillar; 4) recycling jack is in place new crane beam; 5) track forming until new crane beam recovers to use after function, with driving, old crane beam is hung away, completes the replacing of new and old crane beam.
The above-mentioned position that on old crane beam, plane declines in step 3) is lower than pillar bracket face more than 1 meter.
The technique effect that the present invention obtains:
The present invention relies on original production driving, factory building pillar in workshop, has reduced operation easier, accelerating construction progress; Whole method simple practical, safe and reliable.
Accompanying drawing explanation
Fig. 1 is the top view of horizontal transport of the present invention;
Fig. 2 is horizontal transport process front view of the present invention;
Fig. 3 is Renewal process midplane layout drawing of the present invention;
Fig. 4 is front view in Renewal process of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, embodiments of the present invention are described further.
Referring to Fig. 1-4, a kind of quick-replaceable crane beam method that can not use crane construction, it comprises the steps 1) first in driving 1, temporary platform is set, in workshop, can place crane place, new crane beam 2 is lifted in temporary platform and is fixed, utilize driving walking new crane beam horizontal transport to be arrived directly over the old crane beam 4 that need to change; 2) hanging point and the first interim tripod 6 are set on old crane beam two ends pillar 3, utilize jack that new crane beam is mentioned and remove driving, newer crane beam is placed on the first interim tripod and is fixed, extract the hanging point of jack lower end and new crane beam; 3) then utilize jack that old crane beam is removed and dropped to the below that new crane beam is installed, and old crane beam is fixed on the second interim tripod of pillar, the position that on old crane beam, plane declines need be lower than pillar bracket face more than 1 meter; 4) recycling jack is in place new crane beam; 5) track forming until new crane beam recovers to use after function, with driving, old crane beam is hung away, completes the replacing of new and old crane beam.
Protection scope of the present invention is not limited to the above embodiments, and obviously, those skilled in the art can carry out various changes and distortion and not depart from the scope of the present invention and spirit the present invention.If these changes and distortion belong in the scope of the claims in the present invention and equivalent technologies thereof, the intent of the present invention also comprises these changes and is out of shape interior.
