Description
Affiliated technical field
The utility model is used for controllable type miniature rotary core drilling rig that deep-sea cobalt crust is taken a sample, relates to a kind of deep-sea sampler with pre-feeding and device for pre-positioning by it.
Background technology
At present, in the miniature rotary formula corer of having developed both at home and abroad, adopt manipulator to realize core drilling rig in the location of seabed rock layer surface, flexible operation but mechanism's complexity break down easily more.
Summary of the invention
The purpose of this utility model provides a kind of deep-sea sampler with pre-feeding and device for pre-positioning, utilize the hydraulic cylinder of two parallel installations to replace mechanism's complicated mechanical arm, a kind of deep-sea sampler that uses on the bathyscaph that is suitable for developing at home with pre-feeding and device for pre-positioning.
In order to achieve the above object, the technical solution adopted in the utility model is that it comprises:
1) core drilling rig: comprise diamond impregnated bit, clip spring seat, core barrel and reducing joint; Diamond impregnated bit one end is threaded with the clip spring seat front end, and the clip spring seat other end is connected with basket, and the basket other end is connected with reducing joint; Awl snapping head connects water booster system and reducing joint, and the output of core bit and water booster system is linked to be an integral body;
2) water booster system: comprise pressure foot, bearing housing; Pressure foot is connected by bolt with bearing housing, and the hydraulic motor end face is connected with bearing housing;
3) bearing housing and sliding support are welded as a whole, sliding support drives water booster system when frame slides up and down and core bit moves up and down, driving sliding support with two PF cylinder pressures moves up and down, two PF cylinder pressures are installed in the frame both sides, the bottom surface of two PF cylinder pressures is connected with the oil cylinder installation panel, and the tailpiece of the piston rod of two PF cylinder pressures is connected with sliding support with earrings.
4) two pre-PF cylinder pressures adopt the bottom surface mounting means to be connected with fixed panel, 8 through holes that are symmetrically distributed on the fixed panel are connected with bathyscaph, advance panel to be connected to an integral body by processing step and two PF cylinder pressures on two PF cylinder pressure cylinder barrels;
5) two pinnacles of playing the pre-determined bit function are fixed in the welding of frame bottom, and pinnacle and frame are in same axis.
The useful effect that the utlity model has is: it utilizes the pre-PF cylinder pressure of two parallel installations to replace mechanism's complicated mechanical arm, simplified the mechanism of corer greatly, the location of holing when the pinnacle that the bottom penetrates rock layer surface helps creeping into the starting stage, simultaneously can also overcome the countertorque that acts on corer, improve the rigidity of entire mechanism.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is a structural principle schematic diagram of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is the lateral view of Fig. 1;
Fig. 4 is that the B of Fig. 3 is to view.
The specific embodiment
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the utility model comprises core drilling rig and pre-feeding, device for pre-positioning.
Core drilling rig is made up of core bit, water booster system and PF cylinder pressure 3,16, hydraulic motor 15 etc.Core bit comprises diamond impregnated bit 9, clip spring seat 10, core barrel 11 and reducing joint 12, diamond impregnated bit 9 one ends are processed with screw thread, be connected with clip spring seat 10 front end female adapters, clip spring seat 10 other ends also are connected with basket by screw thread, and the basket other end then links to each other with reducing joint 12; Awl snapping head 13 is used to connect water booster system and reducing joint 12, thereby the output of core bit and water booster system is linked to be an integral body.The creeping into moment of torsion and will pass to core bit of water booster system output by awl snapping head 13.
Water booster system comprises critical pieces such as pressure foot 6, bearing housing 5.Pressure foot 6 and bearing housing 5 are connected by bolt, and inside has corresponding transmission and bindiny mechanism to give core bit with the output transmission of torque of hydraulic motor 15.The mode that hydraulic motor 15 adopts end face to install is connected and fixed by bolt and bearing housing 5.Bearing housing 5 is welded as a whole with sliding support 14, and sliding support 14 can drive water booster system when frame 7 slides up and down and core bit moves up and down.Driving sliding support 14 with two PF cylinder pressures 3,16 moves up and down, thereby in order to reduce the installation requirement that whole height of devices adapts to the bathyscaph of current domestic development, two PF cylinder pressures 3,16 are installed in frame 7 both sides, the bottom surface of PF cylinder pressure 3,16 and oil cylinder installation panel 17 usefulness screw bolt and nut are connected and fixed, and tailpiece of the piston rod uses earrings to be connected with sliding support 14.
Operating principle of the present utility model is:
Bathyscaph comes to a complete stop behind a certain position, pre-PF cylinder pressure 2,18 beginnings slowly advance to set flow, after pinnacle 8 is inserted into rock layer surface, the working chamber pressure of pre-PF cylinder pressure 2,18 begins to rise, this force value is detected by pressure sensor, when this value reaches preset value, illustrates that pinnacle 8 has entered rock layer surface, pre-PF cylinder pressure 2,18 stops to advance, and this moment, core drilling rig began to creep into the rock stratum sampling.
