Description
Technical field
The present invention relates to a kind of Bridge Erector, Bridge Erector of specifically a kind of walking without counterweight via hole.
Background technique
With the expansion of Chinese Urbanization scale, for the communal facility in China also perfect, bridge is exactly a kind of common public affairs
Facility altogether.
Bridge refers generally to be erected in rivers,lakes and seas, the structures for making traffic etc. that can smoothly pass through.Bridge generally by
Superstructure, substructure, support and attached structure composition, superstructure are also known as bridge span structure, are across the main of obstacle
Structure；Substructure includes abutment, bridge pier and basis；Support is the biography of the bearing place setting of bridge span structure and bridge pier or abutment
Power device；Attached structure then refers to transition slab at bridge head, truncated cone banking, shore protection, training works etc..
Building bridge is a large-engineering, and people will use various machinery, and Bridge Erector is exactly a kind of common big machinery.Frame
Bridge machine is exactly the equipment that prefabricated beam piece is placed into prefabricated bridge pier and is got on, and is divided into highway bridging machine, railway bridge erecting machine
Etc. several.
Existing highway bridging machine mostly uses the via hole mode of counterweight, it is necessary to could in the case where there is the precast beam of counterweight
Via hole.Supporting leg will be together with the past when via hole, and only to add girder with a part of cross moving track and be self-possessed, ordinary circumstance
The moment of flexure that girder generates when lower via hole will be greater than the moment of flexure that trolley generates in hip when setting a roof beam in place, i.e., the girder of middle leg location is curved
Square is greater than or equal to moment of flexure in hip, needs to increase the material of girder, increases self weight, and stock utilization is low；And front end when via hole
Weight, lower amount of deflection is larger, to tighten rear end counterweight, and girder is made to be in not horizontality, and middle supporting leg generates one to the level being pushed forward
Power may push over middle supporting leg, and there are security risks.
Existing highway bridging machine is needed in cross moving track, middle supporting leg, middle cross moving track and anti-support before mobile using day
Vehicle slings Forward, and a large amount of lifting binding work considerably increases the labor intensity of operator, and working efficiency is low, Guo Wankong
Afterwards, main beam rear end longer dimension, bridge lesser for radius of curvature, rear end is too long to will lead to feeding beam difficulty, sometimes the side of beam piece
Face can encounter the girder of Bridge Erector, and there are security risk, locking mode is using stay bolt and connecting plate anti-support and girder
Lower edge is fixed together, and the stay bolt of this locking mode is easily lost, and the position of web member node cannot lock, it is necessary to before adjustment
The position of supporting leg and middle supporting leg could lock, this is just that construction personnel brings inconvenience.
Summary of the invention
Bridge Erector the purpose of the present invention is to provide a kind of walking without counterweight via hole, to solve in above-mentioned background technique
The problem of proposition.
To achieve the above object, the invention provides the following technical scheme:
