Description

Underwater digging chain
Technical field
The present invention relates to excavating tools, specifically a kind of underwater digging chain.
Background technology
Underwater robot is the effective tool that people are familiar with ocean, development and use ocean.At present, underwater robot is just gradually by the observation type, and operation type develops to strong operation type direction.Along with the fast development and the human exploitation of global communication industry, press at sea-bottom embedment a large amount of extra large cable and oil transportation (gas) pipe to the submarine oil natural gas.Seabed creeping-type robot has bigger towage ability than the formula robot that swims usually owing to can rely on the seabed, is the effective carrier of realizing the seabed ditching operation.Seabed creeping-type robot is at hard silt sea-bottom embedment sea cable and oil transportation (gas) pipe by its chain type excavating tools that carries.Digger chain is the critical component of chain type excavating tools, under fluid motor-driven, by the continuous motion of digger chain, can realize the function of chain type excavating tools ditching in soil.In the prior art, for saving cost, the chain strip adoption land engineering machinery of digger chain is equipped with the creeper tread that be welded with cutting teeth by bolt with fine pith standard caterpillar chain rail on chain.Because chain, creeper tread, connecting bolt are made up of different trade mark steel, they have different current potentials in seawater, as not adding isolation to each other, the metal of different potentials can constitute a lot of small galvanic cells in seawater, active relatively metalwork is eroded very soon, and this can reduce the digger chain working life greatly.
Summary of the invention
In order to overcome above-mentioned deficiency, the purpose of this invention is to provide use on a kind of excavating tools of chain type under water, long working life, simple in structure, underwater digging chain that consumable accessory is convenient to change.
Technical solution of the present invention comprises: chain, creeper tread, chain is a multi-section structure, and creeper tread is positioned at the top of the every joint of chain, it is characterized in that: also comprise division board, separation sleeve, cutting teeth, ejector dozer, the chain that wherein will have more piece is divided into array, and each group series connection forms the closed loop chain; In every group: division board is installed between the joint and creeper tread of chain, separation sleeve is located in the connecting bolt hole that the connecting bolt of creeper tread uses, cutting teeth is installed in the creeper tread upper surface, by connecting bolt, attaching nut chain, creeper tread, division board, separation sleeve, cutting teeth is installed together; Ejector dozer is located on the final section of every group of chain;
Set number is at least 2 on the creeper tread of wherein said cutting teeth joint in every group of chain, and the position of cutting teeth is a cross structure between every pitch chain bar.
The present invention has following advantage:
1. long working life.Underwater digging chain of the present invention has division board, separation sleeve structure, though adopting chain, creeper tread, connecting bolt is different trade mark steel, also can avoid them to have different current potentials in seawater, accomplish each interval from, seawater corrosion resistance in the use is convenient to change consumable accessory.
2. cost is low.Since the chain strip adoption of digger chain of the present invention engineering machinery usefulness, batch process, cheap fine pith standard caterpillar chain rail, simple in structure in addition, reduced cost.
3. applied range.Underwater digging chain of the present invention is used for chain type excavating tools under water, is practicable through evidence, can satisfy ditching operation requirement under water, and is safe and reliable, can be applicable on the chain type excavating tools of different ditching width.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
As shown in Figure 1, 2, underwater digging chain of the present invention is made up of chain 1, creeper tread 2, division board 3, separation sleeve 4, cutting teeth 5, connecting bolt 6, attaching nut 7, ejector dozer 8 in structure, and the chain 1 that wherein will have more piece (present embodiment is 7 joints) is divided into array (present embodiment is that 60 groups of series connection form the closed loop chain); In every group: division board 3 is installed between the first~six joint and corresponding creeper tread 2 of chain 1, separation sleeve 4 is located in the connecting bolt hole that the connecting bolt of creeper tread 2 uses, cutting teeth 5 is installed in and corresponding creeper tread 2 upper surfaces of the first~six joint, by connecting bolt 6, attaching nut 7 chain 1, creeper tread 2, division board 3, separation sleeve 4, cutting teeth 5 is installed together; Be located on the 7th pitch chain bar 1.Creeper tread 2 quantity are identical with the joint number of chain 1.
The described cutting teeth 5 of present embodiment set number on creeper tread 2 is 2, and the position of cutting teeth 5 is cross structure (present embodiment is by the wide distributed architecture that narrows to ejector dozer 8 gradually) between every pitch chain bar 1.
Operating principle is as follows:
The chain 1 of underwater digging chain, creeper tread 2 all adopt engineering machinery standard caterpillar chain rail and creeper tread.For increasing cutting number of teeth amount in the unit length, the present invention selects the caterpillar chain rail and the creeper tread of fine pith for use.Division board 3 and separation sleeve 4 need be selected the high nonmetals manufacturing of crushing strength for use.Division board 3 on the pad, and chain 1 and creeper tread 2 are separated; Be pressed into separation sleeve 4 in the connecting bolt hole that the connecting bolt of creeper tread 2 is used, connecting bolt and creeper tread 2 are separated, thereby guarantee not directly contact between each metal parts.By connecting bolt 6 and attaching nut 7 chain 1, creeper tread 2, division board 3, separation sleeve 4 are fused.Cutting teeth 5 is that road-surface milling machinery is used the standard cutting teeth, and cutting teeth 5 head tips are inlaid with Hardmetal materials.Cutting teeth 5 is fixed by welding in two cutting teeths 5 of 2, creeper treads of creeper tread, 2 welding.Because the width of each cutting teeth is limited, in order to cover whole excavation width, need cutting teeth is divided into groups, on the joint of different chains 1, press the position (see figure 2) that the width arrangement distributes cutting teeth 5, in the end weld an ejector dozer 8 on a creeper tread 2, the soil that front-seat cutting teeth 5 is cut down takes on the ground, can constitute one group of standard by the cutting teeth 5 on 6 creeper treads 2 and an ejector dozer 8 and excavate section.According to excavation depth, can determine the length of digger chain, just can constitute a underwater digging chain by the array standard paragraphs.
In the mining process, after finding that certain cutting teeth damages, can change the creeper tread 2 that is welded with described cutting teeth 5 separately under water.At this moment, only need dismantle 4 connecting bolts 6 and get final product, convenient and swift.
