This utility model discloses the gantry of a kind of size adjustable, two supporting legs being connected including girder and girder, is connected in the grade beam bottom supporting leg, is arranged at road wheel on grade beam, the structure that hoists arranged on the dolly of mobile assembling and dolly on girder;The structure that hoists include hoisting drum, drive hoisting drum rotate driving means, suspender, the fixed pulley group being installed on dolly and for suspender be connected running block and steel wire rope;Girder is trusses;Supporting leg is post group structure, and post group structure is by between multiple steel columns, and adjacent two steel columns, combine along multiple connecting rods of being longitudinally, laterally fixedly installed.The Gantry function of this size adjustable is actually needed according to engineering site, flexible transformation span, width and height, according to field operation condition and lift heavy configuration girder and the quantity of supporting leg column.

Description

The gantry of size adjustable
Technical field
This utility model relates to crane field, particularly relates to the gantry of a kind of size adjustable.
Background technology
The structure of existing gantry generally comprises two supporting legs that girder and girder be connected, is connected in bottom supporting leg Grade beam, the road wheel being arranged on grade beam, the structure that hoists that arranges on the dolly of mobile assembling and dolly on girder;This Rise structure and include hoisting drum, the driving means, suspender, the fixed pulley group being installed on dolly and the use that drive hoisting drum to rotate In the running block being connected with suspender and steel wire rope;Steel wire rope connects suspender by running block, and hanging of goods implemented by this suspender Fortune.When needs lift cargo, dolly moves on girder, and the grade beam of crane drives supporting leg and girder along slide, arrives After reaching precalculated position, implement goods handling.But different according to onsite application situation, height, the width of gantry is wanted Asking different, the girder of existing gantry and the size of supporting leg are the most fixing when dispatching from the factory, though required during onsite application Size is less, also can only be conveyed to destination for existing gantry, cause the waste of human and material resources.
Summary of the invention
In order to solve above-mentioned technical problem, this utility model provides the gantry of a kind of size adjustable, and it can basis Engineering site is actually needed, flexible transformation span, width and height, according to field operation condition and lift heavy configuration girder and supporting leg The quantity of column.
To this end, the technical solution of the utility model is as follows:
A kind of gantry of size adjustable, two supporting legs being connected including girder and described girder, be connected in described Grade beam bottom supporting leg, it is arranged at road wheel on described grade beam, on described girder on the dolly of mobile assembling and described dolly The structure that hoists arranged;The described structure that hoists includes hoisting drum, the driving means driving hoisting drum to rotate, suspender, fixed Fixed pulley group on described dolly and for the running block being connected with suspender and steel wire rope;Described girder is trusses;Described Supporting leg is post group structure, and described post group structure is by between multiple steel columns, and adjacent two steel columns, along be longitudinally, laterally fixedly installed Multiple connecting rods combine.
Further, described girder is type-64 military beam;Described supporting leg is eight or three formula railway light military piers.Or Person, described girder forms with two or more sets type-64 military beam are affixed;Described supporting leg is two or more eight or three formula ferrum Road light military bridge pier is affixed to be formed.
Preferably, described supporting leg top is provided with pier top crossbeam, and described pier top crossbeam is connected with the fixing of girder for realization.Pier Head piece is to ensure that girder and supporting leg are coupled to the important feature part of rigidity door frame.Pier top crossbeam top is provided with and is connected with girder In conjunction with orifice;Beam is provided with the special bolt hole being connected with girder bearing;Tail beam be provided with upwarp end plate in case with the end of girder The lower boom of girder end framework and end plate are fastened in one by framework U-bolt.Pier top crossbeam bottom is provided with and supporting leg column Corresponding bolt hole, is consolidated in supporting leg top with bolt by entablature.On spread out beam and the bilateral legs connection by pier top crossbeam After knot, beam pier structure of standard being met an urgent need is converted into the agent structure of the rigidity gantry crane that can carry out large-tonnage lifting walking.
Preferably, described girder top is provided with double track, for supporting the walking of described dolly.
The gantry of this size adjustable uses standard structure splicing structure, and the general interchangeability of structure is good, unit weight Gently, standardization level is high, transport, easy for installation, it is easy to transfer dismounting between building site.It can use two gantry linkages same The pattern of step operation, can realize 900 tons and following large-sized concrete box beam lifts installation exercise, and can carry out cross-line and lift 900 The ton operation such as box beam entrucking and 900 tons of Bridge Erectors, the upper and lower bridges of beam car.The gantry of this size adjustable can be according to engineering Scene is actually needed, flexible transformation span, width and height, according to field operation condition and lift heavy configuration girder and supporting leg column Quantity.Wide accommodation, job requirements is low, high financial profit;High-speed Passenger Dedicated Lines, inter-city passenger rail can be applied to Deng 900 tons, 750 tons, the 3135 bale handle operations of 500 tons of concrete box girders.
