Abstract
The utility model relates to dredging machines and tools of a trailing suction hopper dredger, particularly to tooth holders of a rake head. The tooth holders of the rake head aim at solving the problems that the replacement of a rake tooth of the rake head is complicated, time consuming and difficult to ensure the welding quality. According to the tooth holders of the rake head, a tooth frame and cast rake tooth holders are employed. The tooth holders of the rake head are characterized in that the cast rake tooth holders are welded on a rectangular tooth frame cover plate; the number of the tooth holders is configured according to the needs; the periphery of the rectangular tooth frame cover plate is provided with symmetrical through holes; the middle of the rectangular tooth frame cover plate is provided with high pressure flushing through holes which are communicated with high pressure flushing holes which are formed on the tooth holders; the back of the rectangular tooth frame cover plate is provided with sealing grooves; sealing rings are embedded in the sealing grooves; the tooth frame is provided with threaded holes which are corresponding to the rectangular tooth frame cover plate; and the rectangular tooth frame cover plate is fastened through bolts and the open tooth frame. The tooth holders of the rake head are suitable for the dredging machines and tools of the trailing suction hopper dredger.
Description
Technical field
The utility model relates to the raking, sucking mud digging ship dredging facility, especially the drag head toothholder.
Background technology
In the dredging works, the dredging soil property constantly changes along with dredging depth, and the trailing suction hopper dredger drag head need be changed the different types of rake teeth of varying number usually to tackle this operating mode.As when dredging loose coarse sand, need in drag head, arrange and arrange cutter type tooth closely; When dredging closely knit fine sand, need in drag head, arrange the cutter type tooth of arranging loose band high-pressure flush; When dredging silt, need in drag head, arrange plough type rake teeth; When the dredging silty clay, need in drag head, arrange the plough type rake teeth of band high-pressure flush.Because toothholder is welded on the drag head braces in traditional drag head, change that toothholder often needs to cut and welding again, this is very loaded down with trivial details to changing the finger placement scheme on the ship, and is consuming time and be difficult to guarantee welding quality.
Summary of the invention
The utility model provides a kind of drag head toothholder, and solving drag head, to change rake teeth loaded down with trivial details, and is consuming time and be difficult to guarantee the problem of welding quality.
The technical solution of the utility model adopts the rake teeth toothholder of braces and casting, it is characterized in that the rake teeth seat is welded on the square braces cover plate of a block length, toothholder number on the braces cover plate is configured on demand, the through hole of symmetry is set around the braces cover plate, there is in the middle of the braces cover plate high-pressure flush through hole to communicate with high-pressure flush hole on the toothholder, at the braces cover plate back side seal groove is arranged, seal groove is embedded in sealing ring, offer the screwed hole corresponding with the braces cover plate on the braces, the braces cover plate is fastening with open braces with bolt.
The utility model advantage is to utilize braces and braces cover plate, can be by the rake teeth kind of the soil property that relates in the dredging works and use, carry out prefabricated to the toothholder on the braces cover plate, only needing replacing to be directed to the rake teeth that changes the dredging soil property in the dredging process gets final product, avoid length consuming time and be difficult to guarantee the problem of welding quality, reduce crewman's working strength simultaneously greatly.
