Abstract
The utility model relates to a digging tool of underwater chain type. In detail, the utility model is a digging tool of asymmetric soil removal underwater chain type. A splint is installed obliquely below the front baffle plate below the digging tool of underwater chain type via a direct connection plate; the splint and direct connection plate are ordinary carbon steel plate with anti-rust paint that is resistant to seawater corrosion. The utility model can be used to remove soil asymmetrically with no influence on digging depth and of good bury effect.
Description
Technical field
The utility model relates to chain type excavating tools under water, specifically is a kind of asymmetric casting chain type excavating tools under water.
Background technology
Because the continuous increase of the operating water depth and the depth of burying, the self-propelled submarine cable burying machine has obtained extensive use.Usually when the hard silt sea-bottom embedment cable of non-rock, the self-propelled submarine cable burying machine need be equipped with the chain type excavating tools.The chain type excavating tools is based on the principle of machine cuts, excavation, by being installed in the continuous motion of the tooth on the cutting chain, is implemented in the function of ditching in the soil.The chain type excavating tools can swing up and down, and adjusts excavation depth as required.In the prior art, chain type excavating tools casting mode is the ground direct-discharging, and both the soil of bottom of trench drove by digger chain and arrives ground, and basic symmetry arrangement is in the both sides of ditch.The center line that departs from burying machine when the chain type excavating tools is installed on the burying machine, and when the beach digging operation, ditching institute casting earth is near a side crawler belt.When serious, institute's casting earth can be deposited in crawler belt the place ahead, is equivalent to reduce excavation depth, and effect is buried in influence underground.
The utility model content
In order to overcome above-mentioned deficiency, the purpose of this utility model provides a kind of excavating tools of chain type under water that can asymmetric casting.
To achieve these goals, the technical solution of the utility model comprises: the front apron below that specifically is chain type excavating tools under water tilts to install a supporting plate; Described supporting plate is installed in described front apron below by direct-connected fishplate bar; Supporting plate, direct-connected fishplate bar are the ordinary carbon steel plate of the rustproof paint that is coated with seawater corrosion resistance.
The utility model advantage:
1. adopt the utility model can asymmetric casting, excavation depth be unaffected, buries underground effective.
2. simple in structure, be easy to change, cost is low, and seawater corrosion resistance.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 tilts to be installed in front apron below topology view before for supporting plate among Fig. 1 by direct-connected fishplate bar.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail.
Referring to Fig. 1, Fig. 2, one has the excavating tools of chain type under water of front apron, and the front apron of chain type excavating tools below tilts to install a supporting plate 1 under water.Specifically be that supporting plate 1 tilts to be installed in the front apron below by direct-connected fishplate bar 2.The angle of inclination that supporting plate 1 is installed is determined according to the viscosity of soil.The viscosity of soil hour, the inclination angle can be littler; When the viscosity of soil was big, the inclination angle can be more greatly.Direct-connected fishplate bar 2 tops are provided with to connect uses unthreaded hole, is used for supporting plate 1 is screwed onto the chain type excavating tools.Supporting plate 1 and direct-connected fishplate bar 2 are by being welded and fused, and the incline direction when supporting plate 1 is connected with direct-connected fishplate bar 2 can be that left side or the right side that is discharged to ditch determined according to soil.When burying operation underground and soil need be discharged to the left side of ditch, the bottom (see figure 3) of the front apron that supporting plate 1 can be installed in by bolt.
Supporting plate 1, direct-connected fishplate bar 2 are the ordinary carbon steel plate, use in seawater for adapting to, and must brush the rustproof paint of seawater corrosion resistance.
Claims (3)
1. asymmetric casting chain type excavating tools under water has the excavating tools of chain type under water of front apron, and it is characterized in that: the front apron of chain type excavating tools below tilts to install a supporting plate under water.
2. press the described asymmetric casting of claim 1 chain type excavating tools under water, it is characterized in that: described supporting plate is installed in described front apron below by direct-connected fishplate bar.
3. press claim 1 or 2 described asymmetric castings chain type excavating tools under water, it is characterized in that: supporting plate, direct-connected fishplate bar are the ordinary carbon steel plate of the rustproof paint that is coated with seawater corrosion resistance.
