The switching installation method of crane girder reinforcing member.
Background technique
ANALYSIS FOR STEEL CRANE GIRDERS is a kind of widely applied structure type, and user can occur in use process and require workshop
Production capacity dilatation prolongs the service life, and the outer dimension of original structure, bearing capacity, durability are not able to satisfy new make
With requiring.When encountering these situations, relate to carry out necessary strengthening construction to former crane girder.Crane girder reinforcing mostly uses under
The mode of reinforcing part on flange plate, truck crane can not directly lift reinforcing member in place, and the life in construction period workshop
Production. art equipment normally produces, and is the difficult point of reinforcement operation in place by reinforcing member installation.
Summary of the invention
The invention patent is designed to provide a kind of switching installation method of strengthening steel crane girder part when not stopping production,
It is in place to realize the installation that crane girder reinforcing member is transferred in the sky, construction period, which normally produces not, influences equipment operation, efficiently solves
Reinforcing member can not directly be lifted problem in place by truck crane of having determined, and easy to operate, ensure that safety, improve construction effect
Rate has accumulated construction experience for similar projects, with meeting the mesh of owner's unit steelmaking equipment dilatation volume increase, creates for owner's unit
Good economic benefit is made.
The present invention installs the hanging apparatus made in advance on T-type reinforcing member, and interim operation is installed on reinforcing member
Platform.Lifting lug is welded on crane girder top flange plate, uses wire rope hanging jack on lifting lug.Truck crane passes through wirerope and T
The crane lifting hole connection of hanging apparatus, lifts by crane T-type reinforcing member and temporary operating platform is hoisted to crane girder side on type reinforcing member
Below face, construction personnel enters temporary operating platform, and jack suspension hook is fallen by hanging apparatus on wirerope and T-type reinforcing member
The connection of chain hole for hoist, truck crane back hook, reinforcing member and temporary operating platform are transferred to immediately below crane girder by jack,
It promotes jack simultaneously reinforcing member is seated under crane girder bottom wing listrium.
The present invention makes temporary operating platform according to reinforcing member specification, and welds together, and provides for high-altitude switching installation
Safe and reliable operating space.Jack is hung in crane girder top flange plate setting lifting lug, realizes that aerial switching will with truck crane
Reinforcing member is mounted in place under crane girder bottom wing listrium.Specific step is as follows:
The first step, processing factory makes T-type reinforcing member (1), and the hanging apparatus made in advance (2) is installed to T-type and is added
On firmware (1), later according to T-type reinforcing member specification fabrication and installation temporary operating platform 3 (Fig. 1)；
Second step welds the first lifting lug 5 on 4 top flange plate of steel crane beam, the second lifting lug 6, the first jack 9, second falls
Chain 10 connect (Fig. 2) with lifting lug the second lifting lug 6, the first lifting lug 5 by the first wirerope 7, the second wirerope 8 respectively；
Third step, truck crane 11 are connect with the crane lifting hole on hanging apparatus 2 respectively by third wirerope 12, are lifted by crane
T-type reinforcing member 1 and temporary operating platform 3 are hoisted to simultaneously below 4 side of steel crane beam (Fig. 3)；
4th step, construction personnel enter temporary operating platform 3, and the suspension hook of the first jack 9, the second jack 10 is passed through respectively
4th wirerope 13, the 5th wirerope 14 are connect with the jack hole for hoist on hanging apparatus 2,11 back hook of truck crane, T-type reinforcing member
1 and temporary operating platform 3 be transferred to immediately below steel crane beam 4 (Fig. 4) by the first jack 9, the second jack 10；
5th step, while the first jack 9, the second jack 10 are promoted, T-type reinforcing member 1 is seated in 4 lower flange of steel crane beam
Under plate (Fig. 5).
It is an advantage of the current invention that realizing, the installation that crane girder reinforcing member is transferred in the sky is in place, and construction period is normal
Production does not influence equipment operation, and it is in place efficiently to solve the problems, such as that truck crane can not directly lift reinforcing member, reinforcing member and faces
When operating platform integration lift, construction safety and quality has been effectively ensured, has improved construction efficiency, it is right under the conditions of not stopping production
Crane girder strengthening construction is the objective economic benefit of owner's unit creativity.
