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

The method of quickly replacing the driving beam without using the crane for construction

technical field

The invention relates to a construction engineering method, in particular to a method for quickly replacing a driving beam that cannot be constructed by a crane.

Background technique

In the maintenance project of the workshop, it is often encountered that only a part of the driving beam is replaced, and the production equipment below the driving beam cannot be dismantled or displaced. Replacing the driving beam in a short time has a great impact on production, and if only manual operation is used, it will be time-consuming and laborious, and there will be great safety hazards.

Contents of the invention

The object of the present invention is to provide a method for quickly replacing the driving beam that cannot be constructed by a crane, and the method is simple and practical in operation, safe and efficient.

The technical scheme adopted in the present invention:

A method for quickly replacing the driving girder that cannot be constructed with a crane. It includes the following steps: 1) First, set up a temporary platform on the driving car, place a crane in the workshop, hoist the new driving girder to the temporary platform and fix it, and use the driving to move it The new driving beam is horizontally transported to the top of the old driving beam that needs to be replaced; 2) Hanging points and first temporary tripods are set on the columns at both ends of the old driving beam, and the new driving beam is lifted and removed from the driving by using the reverse chain, and then the new Place the driving beam on the first temporary tripod and remove the hanging point between the lower end of the upside-down chain and the new driving beam; 3) Then use the upside-down chain to remove the old driving beam and lower it to the bottom of the new driving beam, and fix the old driving beam on the 4) Install the new driving girder in place by reversing the chain; 5) After the track formed by the new driving girder resumes its function, hoist the old driving girder away with the crane to complete the replacement of the old and new driving girder .

The position where the upper plane of the old driving girder falls in step 3) is lower than the corbel surface of the column by more than 1 meter.

The technical effect that the present invention obtains:

The present invention relies on the original production vehicle and factory building pillars in the workshop, reduces the difficulty of operation, and speeds up the construction progress; the whole method is simple, practical, safe and reliable.

Detailed ways

Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

Referring to Figure 1-4, a method for quickly replacing the running girder that cannot be constructed with a crane, it includes the following steps: 1) First set up a temporary platform on the driving 1, place a crane in the workshop, and hoist the new driving girder 2 to the temporary Fix it on the platform, and use the driving to transport the new driving beam horizontally to the old driving beam 4 that needs to be replaced; Lift the driving beam and remove the driving beam, then place the new driving beam on the first temporary tripod and fix it, and remove the hanging point between the lower end of the inverted chain and the new driving beam; 3) Then use the inverted chain to remove the old driving beam and lower it to the new driving beam The bottom of the installation, and fix the old driving beam on the second temporary tripod of the column. The upper plane of the old driving beam must be lower than the corbel surface of the column by more than 1 meter; 4) Install the new driving beam in place by using the reverse chain ;5) After the track formed by the new driving girder resumes its function, hoist the old driving girder away with the crane to complete the replacement of the old and new driving girder.

The scope of protection of the present invention is not limited to the above-mentioned embodiments. Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the scope and spirit of the present invention. If these changes and modifications fall within the scope of the claims of the present invention and their equivalent technologies, the intent of the present invention is also to include these changes and modifications.

Claims (2)

1. the quick-replaceable crane beam method that can not use crane construction, it is characterized in that: 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 pillars (3), utilize jack that new crane beam is mentioned and remove driving, again new crane beam is placed on the first interim tripod and fixes, 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.

2. the quick-replaceable crane beam method that can not use according to claim 1 crane construction, is characterized in that: the position that on old crane beam, plane declines in step 3) is lower than pillar bracket face more than 1 meter.
