Description
Technical field
The utility model relates to a kind of construction machinery and equipment vehicle frame, particularly a kind of dull and stereotyped beam transportation vehicle vehicle frame.
Background technology
The overall structure of beam transportation vehicle can be a giant tyre girder middle, also can be that the many tires of little tire add and put two-beam type.Giant tyre girder middle utilizes the space among the wheel carrier of the left and right sides that the beam transportation vehicle girder is set, and owing to adopting giant tyre to make the tire negligible amounts, uses easy to maintenancely, and tailored version is strong.Put two-beam type owing to adopt little tire car load height to reduce but the many tires of little tire add, be easier to realize the modular combination decomposition, universal better, but because the tire enormous amount is used inconvenient maintenance.
Domestic and international most of 900T beam transportation vehicle all adopts 16 axis, 32 crossbeams, and 64 26.5R25 tires, the mid-pattern of girder, girder and crossbeam adopt the square chest structure, and weight is big; Move the beam dolly and adopt chain wheel drive, dolly drives and control cable unprotect layer, and direct and car body friction is easy to damage, and causes the reliability of whole feeding beam process relatively poor.
The utility model content
The purpose of this utility model is to provide a kind of: the dull and stereotyped beam transportation vehicle vehicle frame that feeding beam process reliability is high.
The purpose of this utility model is achieved in that this vehicle frame has a girder, connects on girder and is no less than two crossbeams, and crossbeam is symmetric arrangement on girder.
Described girder longitudinally is divided into four sections, and each segmentation girder adopts high strength bolt to connect, and is respectively girder I, girder II, girder III and girder IV, and its middle girder I, girder II, girder III are established four respectively, and the girder IV is established five; The last plane of girder is " groove " shape structure, and recess region is installed and moved beam dolly drag chain, and outburst area welding in groove both sides moves the beam vehicle guide.
Described crossbeam is a trapezoidal box girder, the transition of trapezoidal minor face great circle arc, and crossbeam has 34, is distributed on the girder, and crossbeam is connected on the girder by high strength bolt, constitutes 17 axis.
Beneficial effect, owing to adopted such scheme, the cross section structure of girder has than former square case beam that the cross section is little, intensity is high, bearing capacity is big, lightweight characteristics; The character cut in bas-relief zone is used for assembling side by side moves beam dolly drag chain, reduces the car load height; Last plane minor face is used for welding and moves the beam vehicle guide; The ladder type hypotenuse can effectively shorten the car load span, reduces the car load width; Girder longitudinally is divided into 4 sections, each segmentation girder adopts high strength bolt to connect, its middle girder I, girder II, girder III are established four respectively, and the girder IV is established five, and can girder II or girder III being pulled down one section according to the construction needs, be mounted to still can normal operation behind 13 beam transportation vehicles.Each segmentation girder band crossbeam, suspension, tire integral transportation during transportation.34 crossbeam symmetric arrangement constitute 17 axis, adopt high strength bolt to be connected with girder; Crossbeam adopts the trapezoidal box girder structure, has shortened the crossbeam jib-length, has effectively strengthened the intensity of girder and crossbeam connecting portion.The transition of trapezoidal minor face great circle arc, saving in material, moulding is more excellent.
Feeding beam process reliability height has reached the purpose of this utility model.
Advantage: this rubber-tyred beam transportation vehicle, 17 axis are adopted in the car load design, 34 crossbeams, 68 23.5R25 tires under the situation that does not change complete machine rigidity, length, have alleviated complete machine weight, effectively reduce car load height and width, reduce the tire grounding pressure.The beam transportation vehicle vehicle frame is by innovation moulding and optimal design, and load-carrying capacity is more excellent, according to the construction needs car load is torn open to subtract that be mounted to still can normal operation behind 13 beam transportation vehicles.

The specific embodiment
Embodiment 1: this vehicle frame has a girder 1-1, connects on girder and is no less than two crossbeams, and crossbeam is symmetric arrangement on girder.
Described girder 1-1 longitudinally is divided into four sections, and each segmentation girder adopts high strength bolt to connect, and is respectively girder I1, girder II 2, girder III 3 and girder IV 4, and its middle girder I1, girder II 2, girder III 3 are established four respectively, and girder IV 4 is established five; The last plane of girder 1-1 is " groove " shape structure, and " groove " shape structure is concave regions 1-3, installs on concave regions 1-3 and moves beam dolly drag chain, and the groove both sides outburst area welding of concave regions 1-3 moves beam vehicle guide 1-4.
Described crossbeam is a ladder type case beam, the transition of trapezoidal minor face great circle arc, and crossbeam has 34, is distributed on the girder, and crossbeam is connected on the girder by high strength bolt, constitutes 17 axis.
