Abstract
The utility model relates to a floating bridge transitional connecting device, in particular to a floating bridge transitional connecting device for fast connection among different floating bridges. The floating bridge transitional connecting device comprises a transitional frame, which is characterized in that the transitional frame is an oblong shape, whose both long sides are provided with an ear and a pin hole, and the lower portion is provided with a sway brace and a basal plate, wherein the sway brace takes a bar shape, whose upper end is hinged on one side of the lower surface of the transitional frame and the lower end is hinged on the lower side of the connecting end of a relative floating bridge unit under use condition. The basal plate is horizontally arranged and is parallel to the transitional frame, and the center of the upper surface of the basal plate is provided with a pin boss, and the basal plate is hinged on the other long side of the transitional frame by means of the pin boss and a pin shaft, and is placed on another relative floating bridge unit under the use state. The utility model has the advantage of simple connection, small volume and light weight, which does not influence the run of vehicles, and is particularly suitable for the transitional connection between truss-type heavy-type pontoon bridges and other heavy-type pontoon bridges.
Description
Technical field
The utility model relates to a kind of pontoon bridge.Specifically, be the pontoon bridge transition linkage that connects fast usefulness between different pontoon bridges, be particularly useful for the truss-like bridge train heavy and be connected with transition between other bridge train heavy.
Background technology
When on especially big rivers, setting up pontoon bridge,, often need to set up into composite floating bridge with the pontoon bridge unit of number of different types owing to be subjected to the restriction of pontoon bridge equipment.Because the drinking water of dissimilar pontoon bridges differs bigger, the height of pontoon bridge is also inequality, and mutual jointing is not at same position.This pontoon bridge transition linkage with regard to needs employing special use is realized the connection between dissimilar pontoon bridges.At present, the transition linkage that is used for connecting between dissimilar pontoon bridges mainly contains two kinds.A kind of is hinged transition linkage, promptly is between an end of transition linkage and pontoon bridge to be rigidly connected, and adopts between the other end and pontoon bridge to be articulated and connected, and perhaps articulated manner is all adopted at the two ends of transition linkage.Adopt this transition linkage not only to connect relatively difficulty, and the hinged place draft change greatly during vehicle pass-through, influential to the current meeting of vehicle.Second kind is rigidity transition linkage, promptly all adopts between the two ends of transition linkage and two kinds of pontoon bridges to be rigidly connected.Be rigidly connected owing to adopt, require the strength and stiffness of transition linkage all higher.And to improve the strength and stiffness of transition linkage, will cause the volume and weight of transition linkage to increase.
The utility model content
Problem to be solved in the utility model provides a kind of pontoon bridge transition linkage.This pontoon bridge transition linkage, not only ease of connection, do not influence the current of vehicle, and volume is little, in light weight.
For addressing the above problem, take following technical scheme:
Bridge transition linkage of the present utility model comprises transition frame, is characterized in that said transition frame is a rectangle, on its two long limit lug and pin-and-hole is arranged all, and there are diagonal brace and plinth plate in its below.Diagonal brace wherein is shaft-like, and its upper end is hinged on soffit one side of transition frame, and its lower end is hinged under user mode in the link bottom of a corresponding pontoon bridge unit.Said plinth plate is horizontal arrangement and parallels with transition frame, and key seat is arranged in the middle of its upper surface, and it is hinged on another long limit of transition frame by this key seat and bearing pin, and it is shelved under user mode on another corresponding pontoon bridge unit.
Transition frame wherein is end-to-end detachable shape by two block length square plates and is formed by connecting, and the soffit at every block length square plate two ends all has diagonal brace on one side, on the soffit another side of every block length square plate the plinth plate is arranged all.
Take such scheme, have the following advantages:
Because pontoon bridge transition linkage of the present utility model all has lug and pin-and-hole on the two long limits of its transition frame, there are diagonal brace and plinth plate in its below.Diagonal brace wherein is shaft-like, and its upper end is hinged on soffit one side of transition frame, and its lower end is hinged under user mode in the link bottom of a corresponding pontoon bridge unit.Said plinth plate upper surface is hinged on another long limit of transition frame, and it is shelved under user mode on the link upper deck of another corresponding pontoon bridge unit.Whole device only is made of transition frame, diagonal brace and the several parts of plinth plate, not only simple in structure, ease of connection, does not influence the current of vehicle, and volume is little, in light weight.
Description of drawings
Fig. 1 is a pontoon bridge transition linkage structural representation of the present utility model;
Fig. 2 is that schematic diagram is looked on the left side of Fig. 1;
Fig. 3 is a pontoon bridge transition linkage erected state schematic diagram of the present utility model.
The specific embodiment
As depicted in figs. 1 and 2, pontoon bridge transition linkage of the present utility model contains transition frame 3, and this transition frame is a rectangle, its length with treat that the width of frame pontoon bridge adapts, all be processed with lug on its two long limit, be processed with pin-and-hole on the lug.One side of transition frame is hinged by an end of bearing pin 1 and these pin-and-holes and a kind of pontoon bridge unit 10.The below of transition frame 3 is provided with six roots of sensation diagonal brace 5 and two plinth plates 4.Diagonal brace 5 wherein is shaft-like, and its upper end is hinged on soffit one side of transition frame 3, and its lower end is hinged under user mode in the truss 6 link bottoms on the corresponding pontoon bridge unit 10; Said plinth plate 4 is horizontal arrangement and parallels with transition frame 3, and key seat 2 is arranged in the middle of its upper surface, and it is hinged on another long limit of transition frame 3 by this key seat and bearing pin 1, and it is shelved under user mode on another corresponding pontoon bridge unit 10.
Said transition frame 3 contains two block length square plates, and the neighboring terminal corresponding position of this two block lengths square plate is processed with key seat, and the two is detachable shape by bearing pin and pin-and-hole and links together.The soffit of every block length square plate all has three diagonal braces 5 on one side, and said two plinth plates 4 are hinged on respectively on the soffit another side of two block length square plates.
As shown in Figure 3, under the user mode, on that long limit, also be hinged with and import and export longeron 8 near the transition frame 3 of plinth plate 4 one sides, the end that this import and export longeron does not link to each other with transition frame 3 is shelved on the box-shaped bridge joint 9 on the corresponding pontoon bridge unit 10, and another long limit is hinged on the truss 6 on another pontoon bridge unit 10.At last, spread bridge plate 7 on import and export longeron 8 and transition frame 3, personnel and vehicle can pass through.
