The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
The utility model provides a kind of drilling bucket, and this drilling bucket is arranged on rotary drilling rig.This drilling bucket comprises body and is arranged at the water booster system on this body.This water booster system comprises the flexible member for kinetic energy is provided to body, and one end of this flexible member is arranged at the drilling bucket upper bottom portion of this body, and is arranged at the drilling rod below of rotary drilling rig.
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated:
See also Fig. 2 to Fig. 4, the utility model embodiment provides a kind of structural representation of drilling bucket, and this drilling bucket comprises body and is arranged at the water booster system on this body.
This body comprises drilling bucket upper bottom portion 10, drilling bucket lower bottom part 30 and connects the drilling bucket cylindrical shell 20 of drilling bucket upper bottom portion 10 and drilling bucket lower bottom part 30.In this drilling bucket upper bottom portion 10, be provided with connection side 11, drilling bucket release guide rod 12 etc.This connection side 11 is for being connected with the drilling rod square toes of rotary drilling rig, by drilling rod to this drilling bucket transmitting torque and pressure.This drilling bucket release guide rod 12, for release drilling bucket lower bottom part 30, opens this drilling bucket lower bottom part 30, carries out discharging with the silt in this drilling bucket cylindrical shell 20 etc.On this drilling bucket lower bottom part 30, be provided with multiple picks 31 for punching.
This water booster system is spring, elastic caoutchouc, other rigidity or flexible member etc., is preferably spring 40.This spring 40 is arranged between this drilling bucket upper bottom portion 10 and this drilling rod.Particularly, these spring 40 one end are connected with this drilling bucket upper bottom portion 10, are preferably welding, and the other end and this drilling rod offset.When rotary drilling rig carries out in punching process, rock and earth react on the power of drilling bucket and an impact force part and pass to by drilling bucket the main frame of drilling rod and rotary drilling rig, and a part is absorbed by this spring 40 and changes into elastic potential energy and store in addition.In the process that this elastic potential energy can continue to creep at drilling bucket, for drilling bucket provides impact force, therefore, increase the pressure that drilling bucket creeps into downwards, can improve the drilling efficiency of drilling bucket.In addition, in the process of creeping into, this water booster system also can absorb the reaction force to drilling rod, mast and main frame such as a part of rock, pan soil, can reduce the destruction of excessive reaction force to drilling rod, mast and main frame, improve the application life of drilling rod, mast and main frame, also can increase the stability of host work simultaneously.
The stability of working in order to improve this spring 40, prevent the generation of its phenomenon of vacillating now to the left, now to the right, this water booster system can also comprise guide rod 50, and this guide rod 50 is fixed in this drilling bucket upper bottom portion 10, this spring 40 is set on this guide rod 50, and this guide rod 50 plays the effect of guiding to this elasticity 40.Like this, in the direction that this spring 40 just can extend at this guide rod 50, do stretching motion and the phenomenon that is unlikely to swing, so more can improve the stability of drilling bucket operation.Certainly,, owing to there being this guide rod 50 to lead, this spring 40 can not be connected with this drilling bucket upper bottom portion 10, but only supports in this drilling bucket upper bottom portion 10.
In order further to improve the application life of drilling rod, reduce this impact of spring 40 to drilling rod, this water booster system also comprises balancing weight 60.On this balancing weight 60, offer the through hole corresponding with this guide rod 50 positions, this guide rod 50 is arranged in this through hole, and this balancing weight 60 is offseted with this spring 40.In the process of creeping into, this spring 40 is compressed and when producing elastic potential energy or overcoming elastic potential energy, its active force all acts directly on this balancing weight 60, and do not occur directly to contact with this drilling rod, therefore can prevent from acting on because of excessive active force the shortening that causes drilling rod working life on drilling rod.
Below the water booster system course of work in the time creeping into operation that includes spring 40, guide rod 50 and balancing weight 60 is described.
Drilling bucket is in drilling process, and rock and earth react on the power of drilling bucket and impact a part and passes to drilling rod and main frame by drilling bucket, and a part is absorbed by this spring 40 and changes into elastic potential energy and store in addition.This spring 40 promotes this balancing weight 60, the gravitional force that makes elastic potential energy change into again balancing weight 60 stores, and gravitional force changes into kinetic energy again and acts directly on this drilling bucket upper bottom portion 10 and pick 31 and (also comprise that the static pressure of mentioning in background technology is also applied on this drilling bucket upper bottom portion 10 and pick 31).This pick 31 carries out shock machine to rock and earth and creeps under the effect of above-mentioned active force, can make drilling efficiency increase substantially, and has improved the operating efficiency of rotary drilling rig punching.
Above-mentioned guide rod 50 is fixed in this drilling bucket upper bottom portion 10, therefore, guide rod 50 and drilling bucket upper bottom portion 10 cannot be separated, and this has just caused a set of water booster system only can be used for a body.In order to make a set of water booster system disassemble and to be applied on the body of another one drilling bucket from the body of a drilling bucket, this guide rod 50 can be screwed onto in this drilling bucket upper bottom portion 10, one end of this guide rod 50 can offer external screw thread, and offer the screwed hole matching with this external screw thread on the top of drilling bucket upper bottom portion 10, by coordinating of external screw thread and internal thread, can facilitate this guide rod 50 installation and removal.Like this, can make this water booster system be arranged on multiple bodies, improve the versatility of this water booster system.
In the above-described embodiments, this drilling bucket bores for dragging for husky bucket, and its drilling bucket lower bottom part 30 needs can open to carry out discharging, and this drilling bucket can be also a cylinder brill, and the drilling bucket lower bottom part of this type of drilling bucket is without opening, therefore, and without drilling bucket release guide rod.
The utility model embodiment also provides a kind of rotary drilling rig that is provided with this drilling bucket.
Because above-mentioned drilling bucket has above-mentioned technique effect, therefore, the rotary drilling rig that is provided with this drilling bucket also possesses corresponding technique effect, and its specific implementation process is similar to the above embodiments, does not hereby repeat.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
