Description
Technical field:
The invention belongs to field of mechanical technique, be specifically related to a kind of for boring the sinker bar structure of the damping noise abatement of hard layer.
Background technology:
Boring or broken actual requirement, determining the development characteristic of the effectiveness of performance etc. of current drill bit, and in reality when punching a hole or during broken material, body of wall broken and piling boring while building viaduct when needed the broken or housing demolition of local road at urban district internal cause engineering factor, all produce some defects, during such as, body of wall broken at city's internal road broken, noise is large, ear-piercing; During piling boring, simply by virtue of the height that lifts drilling rod integral body, rely on self gravitation to realize percussive drilling, its efficiency is not high like this, also be difficult to squeezed into carry out fragmentation, and drill bit be easily worn or damage, being therefore badly in need of development and being applicable to drill bit structure or the device that reality needs.The fast development of economy at present still more, have a large amount of railways, the development & construction of the infrastructure such as highway, harbour and factory building, simultaneously also with a large amount of engineerings such as impact roadbed, impact rotary head for being contained on Churn drill, concrete foundation, wall, brick wall, rock are holed or fragmentation.
Summary of the invention:
The sinker bar structure that the object of the invention is to overcome problems of the prior art and the damping noise abatement that a kind of impact strength is high, noise is little, target efficiency is high is provided.
Technical scheme of the present invention is achieved in that the sinker bar structure of damping noise abatement, comprises
-mono-drilling rod, its central axis is to being hollow-core construction;
-mono-drill bit, is located at the axial end face of drilling rod;
-mono-spring, being placed in is axially in the drilling rod of hollow-core construction;
-mono-fixed block, is arranged on the bottom in drilling rod with one end of drill bit, for one end of fixing spring;
Double helix draw-in groove on-mono-, is opened in respectively on relative edge, the axial other end of drilling rod;
-mono-stull axle, is laterally placed on double helix draw-in groove, and its two ends exceed double helix draw-in groove, and it exceeds part for supporting following drilling rod top cover for the other end of fixing following spring;
-mono-drilling rod top cover, it is sleeved on the top of drilling rod.
The top of drilling rod top cover is regular polygon prism shape, and bottom is cylindrical shape;
In drilling rod top cover lower end surface, offer suit mouthful;
Top end face in suit mouth is provided with and the lower double helix shape draw-in groove that is laterally placed with the upper double helix shape draw-in groove corresponding matching of stull axle;
The edge relative in drilling rod top cover bottom offers respectively stull shaft relief.
Drill bit is located at the axial end face of drilling rod and is structure as a whole with drilling rod.
At described spring, it is extension spring.
One end of described spring is placed in the bottom of fixed block, and fixes by fixed block center with along the screw of fixed block periphery equidistant position setting.
In the middle of described stull axle, be fixed with guide peg perpendicular with stull axle and that intert in spring centre position.
Good effect of the present invention: the spring arranging in the sinker bar structure of this damping noise abatement is in reverse turn operation, because along with stull axle rotates on the upper double helix draw-in groove of drilling rod upper end, thereby stretched spring, when stull axle turns to most significant end by the spiral channel least significant end of drilling rod upper end, because the stretching of spring makes its savings elastic force, when falling suddenly, the elastic force of savings discharges, the downward active force of drill bit is increased greatly, this mainly relies on the elastic force effect work of spring savings when being reversion, it also can reduce to produce when apparatus impacts drilling rod the noise of shrillness simultaneously, when forward operates, because the two ends of stull axle are stuck on upper double helix draw-in groove, it can drive drilling rod to rotate, and then can drive drill bit to rotate to carry out operation, when reverse turn operation, drilling rod and drill bit that this device clashes into bottom carry out operation in a word, when forward operates, be to drive drilling rod and bit to carry out operation.
Accompanying drawing explanation:
Fig. 1 is the structural representation of drilling rod in the present invention.
Fig. 2 is the partial structurtes sectional view of drilling rod in the present invention.
Fig. 3 is the structural representation of drilling rod top cover in the present invention.
Fig. 4 is the structural representation that in the present invention, drilling rod top cover is arranged on drilling rod upper end.
In figure: drilling rod 1, drill bit 2, upper double helix shape draw-in groove 3, stull axle 4, spring 5, fixed block 6, drilling rod top cover 7, stull shaft relief 8, guide peg 9, bore screw 10, suit mouth 11, lower double helix shape draw-in groove 12.
The specific embodiment:
Embodiment: as Figure 1-4, the sinker bar structure of this damping noise abatement comprises drilling rod 1, its central axis is to being hollow-core construction;
Drill bit 2, is located at the axial end face of drilling rod 1;
Spring 5, being placed in is axially in the drilling rod of hollow-core construction;
Fixed block 6, is arranged on the bottom in drilling rod with one end of drill bit, for one end of fixing spring 5;
Upper double helix draw-in groove 3, is opened in respectively on relative edge, the axial other end of drilling rod 1;
Stull axle 4, is laterally placed on double helix draw-in groove 3, and its two ends exceed double helix draw-in groove 3, and it exceeds part for supporting following drilling rod top cover 7 for the other end of fixing following spring 5;
Drilling rod top cover 7, it is sleeved on the top of drilling rod 1;
The top of drilling rod top cover 7 is regular polygon prism shape, and bottom is cylindrical shape;
In drilling rod top cover 7 lower end surface, offer suit mouth 11;
Top end face in suit mouth 11 is provided with and the lower double helix shape draw-in groove 12 that is laterally placed with upper double helix shape draw-in groove 3 corresponding matching of stull axle 4;
The edge relative in drilling rod top cover 7 bottoms offers respectively stull shaft relief 8;
