Description
The technical field is as follows:
the utility model relates to a marine facilities field, in particular to cutter-suction type inhales mud shield and constructs can dismantle claw.
Background art:
in the prior art, the excavatability of a 3500m3/h large cutter suction dredger for different soil qualities is as follows: mucky soil, silt soil, soft clay and non-compact sandy soil are easy to excavate; dense sand, broken stones and soft rocks are still capable of being excavated, and hard clay and medium-strength rocks are difficult to be excavated. With the development of water transportation engineering, the engineering projects of dredging and hydraulic filling engineering under the working condition of severe soil quality are more and more, the trailing suction dredger is not suitable for dredging construction of hard clay, and the grab dredger and the cutter suction dredger can excavate soil, but the construction efficiency is extremely low, and the production energy consumption is large. According to the severe soil quality encountered by the prior dredging engineering in China, the danger problem of the cutter suction dredger with hard clay and soft stone soil is the most, and the construction efficiency is the lowest.
The cutter suction type mud suction shield is excavating equipment necessary for a large cutter suction ship, a cutter arm is integrally cast with a plurality of cutter teeth in the prior art, and the cutter suction type mud suction shield is frequently used for excavating sandy soil and rock, so that the loss is serious, the cutter suction shield needs to be shut down after being used for a period of time, the cutter part of the shield is integrally replaced, time and labor are wasted, and the cost is high. It is therefore envisaged to provide a new configuration of apparatus to address this problem.
The utility model has the following contents:
the utility model aims at improving and innovating the defects and problems existing in the background technology, and provides a cutter-suction type mud-suction shield detachable claw part.
The utility model adopts the technical proposal that:
a cutter-suction type mud-suction shield detachable claw: the cutter-suction type mud-suction shield is provided with a reamer, the reamer is provided with a reamer ring, a reamer hub is arranged at the center of the front end of the reamer ring, a plurality of reamer arms are connected between the reamer hub and the reamer ring, the reamer arms are provided with a plurality of cutter tooth seats, and the front ends of the cutter tooth seats are movably provided with replaceable cutter tooth parts; the reamer wheel hub and the reamer ring are coaxially arranged and are axially separated by a certain distance, the reamer arms are of a spiral structure, and the reamer arms are uniformly distributed along the circumferential direction.
The reamer arms are preferably five in number, and can be six in number.
The rear end of the reamer ring is connected to a mud outlet, and the mud outlet is connected to a conveying pipeline.
The upper end of the cutter tooth seat is provided with a threaded hole, the cutter tooth component is also provided with a threaded hole, and the cutter tooth seat and the cutter tooth component are fixedly installed through bolts; the connection can also be fixed by adopting a snap-fit joggle joint mode.
Compared with the prior art, the beneficial effects of the utility model reside in that:
the utility model discloses a be provided with many sword toothholders on the reamer arm, sword toothholder front end movable mounting has the structure of removable sword toothpart, can receive the wearing and tearing back of certain degree at the sword tooth, dismantles the change with the sword toothpart, compares and wholly dismantles the change labour saving and time saving with the reamer, has more practiced thrift a large amount of equipment replacement expenses.
Description of the drawings:
fig. 1 is a schematic front view of the present invention.
Fig. 2 is a schematic side view of the present invention.
Fig. 3 is a schematic view of the structure of the connection between the cutter tooth seat and the replaceable cutter tooth component according to the present invention.
The specific implementation mode is as follows:
the invention will be described in further detail by way of example with reference to the accompanying drawings:
a cutter-suction type mud-suction shield detachable claw: the cutter-suction type mud-suction shield is provided with a reamer, the reamer is provided with a reamer ring 2, a reamer hub 1 is arranged at the center of the front end of the reamer ring 2, a plurality of reamer arms 3 are connected between the reamer hub 1 and the reamer ring 2, a plurality of cutter tooth seats 4 are arranged on the reamer arms 3, and a replaceable cutter tooth part 5 is movably arranged at the front end of each cutter tooth seat 4; reamer wheel hub 1 and reamer circle 2 coaxial arrangement and keep apart certain distance in the axial, reamer arm 3 is helical structure, and each reamer arm 3 is evenly arranged along circumference moreover. The reamer arms 3 are preferably five, and may be six. The rear end of the reamer ring 2 is connected to a mud outlet which is connected to a conveying pipeline. The upper end of the cutter tooth seat 4 is provided with a threaded hole, the cutter tooth component 5 is also provided with a threaded hole, and the cutter tooth seat and the threaded hole are fixedly installed through a bolt 6; the connection can also be fixed by adopting a snap-fit joggle joint mode.
The embodiments of the present invention are only descriptions of the preferred embodiments of the present invention, not right the present invention is designed and limited, without departing from the design concept of the present invention, the technical personnel in the field should fall into the protection scope of the present invention for various modifications and improvements made by the technical solution of the present invention, and the technical contents of the present invention are all recorded in the claims.
