The chassis structure is provided with a crawler and drives the equipment to move horizontally along the Y direction so as to ensure spatial three-dimensional operation of the load and meet the need for linear or curved layout of the reactor of a nuclear power plant.
Description
Technical field
The present invention relates to a kind of crawler type gantry crane, be applicable to the construction of nuclear power station of AP1000 type and similar applications.
Background technology
Along with greatly developing of domestic nuclear power, the cycle of the construction of nuclear power station and cost receive great concern.Will build four reactors because every nuclear station is minimum, and according to the addressing requirement, four or a plurality of reactor all adopt straight line or broken line to arrange.Be beneficial to the large part lifting in the construction of nuclear power station.The hanging device that adopts at present mainly is large-scale crawler crane or stationary slewing crane.Facts have proved that these two kinds of weight-lifting equipments all exist some to lack limit to the construction of nuclear power station.Although it is mobile that crawler crane can realize that band carries, along with the increase of lifting altitude, hoisting capacity can sharply descend.And reactor top building weight on the contrary can be larger along with the increase of height, AP1000 heap type especially, even select the crawler crane that can satisfy reactor top building weight, the cost that is doubled and redoubled also can make the builder hang back; The stationary slewing crane hoisting capacity is relatively larger, but the position fix, can only carry out construction operation for the construction of one or two reactor, move if tear open, then excessive and cycle of cost can not meet the demands.As seen, the former is subject to superstructure; The latter is subject to the construction of a plurality of heaps.As if comparatively speaking, transfer crane can remedy the shortcoming of above two kinds of hoisting cranes, if but a plurality of reactors are the broken line arranged, and be limited to transfer crane and can't realize the broken line operation, so transfer crane equally also has shortcoming.
Summary of the invention
Proposition of the present invention, be intended to design a kind of crawler type gantry crane, by the transformation to transfer crane, make it be applicable to the construction of nuclear power station and other similar applications, especially the construction of AP1000 nuclear station heap type, and then shorten the Nuclear Power Station cycle and effectively save laid down cost.
Technical solution of the present invention is achieved in that
A kind of crawler type gantry crane, comprise by lifting mechanism, the dolly that operating unit and trolley frame consist of, by girder, end carriage, supporting leg, the portal-framed structure that cross sill and trolley track consist of, by swing bearing, chassis structure, the crawler belt operating unit that track sprocket and HM Hydraulic Motor consist of, dolly wherein has relatively independent structure, lifting mechanism wherein is supported in trolley frame, trolley frame carrying lifting mechanism is made the directions X horizontal motion along the trolley track on the portal-framed structure, trolley track is installed on the girder of portal-framed structure, girder and end carriage then connect to form framework by high strength bolt, framework is connected in the supporting leg upper end by high strength bolt, the lower end of supporting leg is connected in the two ends of cross sill by high strength bolt, it is characterized in that: the lower end of described cross sill is welded with the cross sill lower flange, and is connected with the inner ring bolt of swing bearing; The structure flanges of described chassis structure then is connected with the outer ring bolt of swing bearing.
Compared with prior art, advantage of the present invention is apparent, is mainly manifested in:
1, combines the characteristics of crawler crane and transfer crane, realized that the band of rated load carries movement.
2, be not subjected to the restriction of trapped orbit, use flexibly; Be convenient to dismounting, be fit to the strange land repeated usage.
