Description
Technical field
The present invention relates to a kind of desilting equipment, particularly to a kind of for the device of walking in marsh.
Background technology
In prior art, there is a kind of marsh driving gear, its publication number CN200992121Y, publication date 2007-12-19, the primary structure of this device includes two symmetrically arranged buoyancy aids, before and after each buoyancy aid, end is correspondingly arranged on two groups of sprocket wheels, often it is provided with conduction chain between group sprocket wheel, around the home in the periphery of buoyancy aid before and after described conduction chain, directive wheel it is provided with between conduction chain and buoyancy aid, two conduction chains of each buoyancy aid are connected through some track shoes arranged in parallel, are provided with bindiny mechanism between two buoyancy aids, and track shoe is the concave structure that middle part caves inward.This apparatus structure intensity is good, walking time be difficult to the purpose skidded, safety coefficient is high, can be used for river course, shoal, marshland.It is disadvantageous in that: due to the particularity of buoyancy tank crawler unit, require that it has relatively low grounding pressure, so as to adapt in marsh, the walking of muddy terrain, and it needs have amphibious function, can automatic floating boat when the depth of water exceedes its operating depth.Therefore air buoyancy tank crawl running gear needs to possess the crawler unit of relatively large grounded area and has the buoyancy tank of enough buoyancy, in view of whole chassis by land with water in work time stability, generally its lateral dimension is bigger, typically it is above the size range of convention traffic transport, transport after needing during transport to dismantle the buoyancy tank of both sides, assemble again after arriving construction site, therefore transition transport trouble, often there are trees the both sides, river course also having rural area, and wider chassis is poor by property.During as considered transport by property, can must be less by the width design of whole device, but its anchorage operationally is away from not.Therefore, when the land mobile of this device or transport by property and on the water operation time resistance to capsizing between be conflict, the solution the most not yet having had.
Summary of the invention
It is an object of the invention to provide a kind of rail-variable marsh driving gear so that it is buoyancy tank track space can be adjusted, to facilitate transport, and also more preferable by property when walking, good stability during operation.
nullThe object of the present invention is achieved like this: a kind of rail-variable marsh driving gear，Including two symmetrically arranged buoyancy tanks，Before and after each buoyancy tank, end is correspondingly arranged on two groups of sprocket wheels，Often it is provided with conduction chain between group sprocket wheel，Around the periphery being contained in buoyancy tank before and after described conduction chain，It is connected through some track shoes between two conduction chains of each buoyancy tank，Be arranged in parallel on described each buoyancy tank two fixing steel pipes，It is connected through two slip steel pipes between two buoyancy tanks，Described slip steel pipe two ends are inserted in the fixing steel pipe of correspondence respectively，It is provided with turntable between in the middle part of slip steel pipe，Apparatus for work is installed on turntable，Before and after turntable, side is respectively equipped with link，Column it is provided with on the downside of link，Described column is fixedly connected on slip steel pipe，It is respectively equipped with oil cylinder in each fixing steel pipe，Described oil cylinder one end is connected fixed with fixing steel pipe，The other end is connected with slip steel pipe.
When the present invention uses, having following several working method, one is land transport or walking manner, and in the cylinder body of the piston rod retraction oil cylinder of oil cylinder, now, the lateral dimension of whole device is minimum, good by property；It two is floating walking mode, and now, the piston rod of oil cylinder stretches out, and fixing relatively slides between steel pipe and slip steel pipe, and fixing steel pipe drives buoyancy tank to both sides displacement, makes the rail spacing between two buoyancy tanks increase, improves the resistance to capsizing of device.In the present invention, owing to oil cylinder is arranged in fixing steel pipe so that oil cylinder does not contacts with extraneous mud, sewage etc., it is ensured that cylinder efficient is in relatively clean space, and therefore, its work is relatively reliable.Compared with prior art, the present invention has taken into account land by property with anti-overturning waterborne, while making device be readily transported, also can carry out operation the most on the water.This device is be applicable to the desilting of marsh.
