Abstract
The utility model provides a kind of large span steel structure roof entirety lift structure, including flexible steel twisted wire, hydraulic rockshaft and leading truck, hydraulic rockshaft is set to the side of leading truck, the lift side of hydraulic rockshaft is fixed in one end of flexible steel twisted wire, the other end of flexible steel twisted wire is bypassed by the upper end of leading truck, and for being connected with steel structural roof, steel structural roof is drawn as load-bearing rigging.The problems such as required precision height big to avoid steel structural overhead weld job amount, assembled, security protection difficulty is big, and it is complex to construct, and difficulty is big.Belong to construction and assists novel technical field of construction.
Description
Technical field
The utility model relates to a kind of large span steel structure roof entirety lift structures, belong to construction and assist novel apply
Work technical field.
Background technique
With the development of the social economy, steel construction structures are more and more, the difficulty of construction of steel construction is increasingly
Greatly.Traditional Construction of Steel Structure method has installation at high altitude etc., but installation at high altitude is for Construction of Steel Structure, in safety assurance
There is biggish difficulty in terms of quality control on construction.
Summary of the invention
The purpose of this utility model is that: a kind of large span steel structure roof entirety lift structure is provided, to avoid steel knot
Structure overhead welding workload is big, and assembled required precision is high, and security protection difficulty is big, and it is complex to construct, and difficulty is big etc. asks
Topic.
To solve the above problems, such a large span steel structure roof entirety lift structure of proposed adoption, including flexible steel
Twisted wire, hydraulic rockshaft and leading truck, hydraulic rockshaft are set to the side of leading truck, and liquid is fixed in one end of flexible steel twisted wire
The lift side of lifter is pressed, the other end of flexible steel twisted wire is bypassed by the upper end of leading truck, and for being connected with steel structural roof,
Steel structural roof is drawn as load-bearing rigging.
Compared with prior art, the utility model uses flexible rigging load-bearing, as long as there is reasonable load-bearing suspension centre, is promoted high
It spends unrestricted；Automation degree of equipment is high, and flexible operation, safety is good, and high reliablity, use is wide, versatile；It saves
The operation of large-scale crane can greatly save mechanical equipment, human resources；Using whole promotion, spelled on ground in face of steel construction
Dress and welding, smaller safety management and quality testing difficulty and while convenient for control construction quality, reduce difficulty of construction
And can make full use of Contraction in Site face, shorten the whole duration.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is computer control principle figure.
Specific embodiment
To keep the purpose of this utility model, technical solution and advantage clearer, the utility model will be made into one below
The detailed description of step.
Embodiment:
Referring to attached drawing 1 and Fig. 2, the present embodiment provides a kind of large span steel structure roof entirety lift structures, including flexibility
Steel strand wires 1, hydraulic rockshaft 2 and leading truck 3, hydraulic rockshaft 2 are core-theaded type structure, and hydraulic rockshaft 2 is set to leading truck 3
Side, one end of flexible steel twisted wire 1 is fixed on the lift side of hydraulic rockshaft 2, and the other end of flexible steel twisted wire 1 is by leading truck
3 upper end bypasses, and for being connected with steel structural roof (truss lift unit), is promoted as load-bearing rigging traction truss single
Member, every good leading truck 3 of 2 configured in advance of hydraulic rockshaft, the export for facilitating its top to reserve excessive steel strand wires are smooth.Extra
Steel strand wires can freely be dredged backward, downwards along platform is promoted.Hydraulic pump source system is that hydraulic rockshaft 2 provides power, and passes through
Controller is controlled and is adjusted to more or separate unit hydraulic rockshaft 2, and hydraulic synchronizing lifting computer control system is executed
Instruct simultaneously feedback data.
Its comprehensive construction method is as follows:
Step 1: installation hydraulic synchronizing lifting system equipment, including hydraulic pump source system, hydraulic rockshaft 2 and sensor,
Hydraulic pump source system is that hydraulic rockshaft 2 provides power, and sensor includes anchorage sensor, displacement sensor and pressure sensing
Device debugs hydraulic synchronizing lifting system, tensioning flexible steel twisted wire 1, so that 1 uniform stressed of all flexible steel twisted wires；
Step 2: whether all interim measures of inspection truss lift unit and hydraulic synchronizing lifting, which meet design, is wanted
It asks；Confirm it is errorless after, according to the 20% of design load, 40%, 60%, 70%, 80%, 90%, 95%, 100% sequence by
Grade load, until lift unit is detached from platform for lining；
Step 3: after roof truss promotes about 150mm, pause is promoted；The absolute altitude for finely tuning each suspension centre of lift unit, makes
It is in level, and stands 4~12 hours, checks again for truss lift unit and hydraulic synchronizing lifting interim measure is no different
Often, after confirming situation without exception, start formal promoted；
Step 4: the whole roof truss lift unit that promoted is promoted to close to installed height mark pause；
Step 5: measurement truss lift unit each point actual size after checking and handle with design value, reduces and promotes speed
Degree continues to lift up roof truss close to design position, and each " fine tuning, crawl " function of promoting suspension centre and pass through computer system makes
Each suspension centre that promoted reaches design position, meets docking and requires；
Step 6: after roof truss mating operation, each suspension centre sequence of hydraulic lifting system is unloaded, and turns roof system self weight
It moves in main structure, reaches design point；Hydraulic lifting device is removed, it is entire to promote operation completion.
Above embodiments are only to illustrate rather than limit the technical solution of the utility model, although referring to above-described embodiment pair
The utility model is described in detail, it will be apparent to an ordinarily skilled person in the art that: still can to the utility model into
Row modification or equivalent replacement should all without departing from any modification or partial replacement of the spirit and scope of the utility model
Cover in the scope of the claims of the utility model.
