Abstract
The utility model relates to a bridge used for suction dredges. The bridge is characterized in that a main beam is provided with at least two pores and is internally provided with at least two pieces of suction dredge pipelines. The main beam can work as a bearing main body; besides, the interior of a pipe column can also act as the space for the paving of the suction dredge pipelines of a suction dredge. The original more than 10 pieces of suction dredge pipes attaching on the exterior of the main beam disappear then, thereby ensuring simple appearance and light structure of the entire bridge. A column-shaped steel tube is used as the main beam, thereby making section modulus in all directions identical and ensuring comparatively strong torsion resistance ability and obviously saving materials. As to a common suction bridge with a gauge of 8 to 12m, the weight of a pipe column-shaped main beam can be reduced by one third to one fourth, according to checking. In a siphoning type suction dredge, a pipe column-shaped main beam possessing suction dredge has a siphoning pipeline positioned in the main beam, thus, the possibility of damage of the bridge is greatly lowered thanks to the protection of the main beam as a shell. Moreover, two driving mechanism bases attaching on the main beam are thereby saved, thereby ensuring smooth lines and tidy appearance for the entire bridge. Siphoning type suction dredge has more marked advantages because the pipe column-shaped main beam substitutes the suction dredge pipelines.
Description
Technical field:
The utility model relates to the water works special equipment, specifically a kind of crane span structure that is mainly used in suction dredge.
Background technology:
The crane span structure that is used for suction dredge of the prior art, it mainly comprises girder, the end carriage that is connected with girder, be contained in the road wheel and the driving mechanism thereof at end carriage place, on girder, two driving mechanism bases to be installed toward contact, suction dredge is when work, and main beam stress situation more complicated wherein mainly contains vertical moment of flexure, horizontal bending moment, moment of torsion etc.Girder commonly used owing to constructional reason, differs for the ability to bear of above-mentioned three kinds of loads, and is especially the poorest to the ability to bear of moment of torsion.If careful checking computations will find that the cross section property of girder is appropriate to some load, and concerning some load, then are too rich, this just causes the waste of material unavoidably.Environmental design relatively is particular about in the water works, the architectural concept uniqueness, and all kinds of structure lines are soft, and color is simple and elegant.And suction dredge girder commonly used, superfluous heavy as structures that then seems such as case beam, trusses, L types, profile is numerous and diverse, the dredging tube road be exposed at pool side in disorderly and surrounding environment inharmonious, be unfavorable for environmental protection.
Summary of the invention:
The purpose of this utility model is to provide a kind of crane span structure that is used for suction dredge, and it can overcome some shortcomings of the prior art.
To achieve these goals, the technical solution of the utility model is:, a kind of crane span structure that is used for suction dredge, it mainly comprises girder, the end carriage that is connected with girder, be contained in the road wheel and the driving mechanism thereof at end carriage place, it is characterized in that: be provided with at least two holes at girder, at least two dredging tube roads are housed in the girder.
The utility model discloses owing to be provided with at least two holes at girder, at least two dredging tube roads are housed in the girder, girder is except conduct carrying main body, tubing string inside can also be as the space of laying in suction dredge dredging tube road, more than ten dredging tube road concealment originally can only seeking connections with in the girder outside loses, make the complete machine moulding succinct, structure is light and handy.Make girder with steel cylindrical tube, each is to the section modulus unanimity, and anti-twisting property is stronger, obviously can economical with materials.The suction dredge that rail square commonly used is 8～12 meters through adjusting, adopts pipe string shaped kingpost weight can alleviate 1/3～1/4.In the hydrocone type suction dredge, the pipe string shaped kingpost suction dredge places girder inside with siphon piping, has girder to make shell protection, the less possibility that damage is arranged.And saved two driving mechanism bases that are attached on the girder, and the lines flow smoothly to make complete machine, and outward appearance is clean and tidy, and in the pump suction type suction dredge, pipe string shaped kingpost will replace the spoil disposal pipeline, and its advantage is more remarkable.

Fig. 2 is the A-A view among Fig. 1
The vertical view of Fig. 1 that Fig. 3 is
The specific embodiment:
The utility model will be further described below in conjunction with drawings and Examples.
The utility model pipe mainly comprises girder 1, the end carriage 2 that is connected with girder 1, be contained in the road wheel 3 and the driving mechanism 4 thereof at end carriage place, it is characterized in that: be provided with at least two holes at girder 1, at least two dredging tube roads 5 are housed in the girder 1, and the enforcement middle girder is approximate to be tubing string shape or rectangle, and the dredging tube road enters in the girder by hole, present embodiment is equipped with 12 dredging tube roads in girder 1, the dredging tube road evenly distributes along the inwall of girder.Pipe string shaped kingpost can be welded into ready-made steel pipe or steel plate roll bending, and manufacture craft is obviously simple and direct than other girders commonly used.Driving mechanism only with end carriage under live axle link, do not contact with girder, driving mechanism and base all are contained in the end carriage place, and the girder inside that is laid in, dredging tube road, not only outward appearance is clean and tidy, and is convenient to maintenance, mediation, mark 6 in the accompanying drawing is a track, the cleaning shoe that 7 expressions are connected with girder, these are prior art, are not described specifically at this.
Claims (3)
