Abstract
The utility model discloses a practical tricone bit dismantling device. The practical tricone bit dismantling device comprises a clamping jaw ring, a clamping jaw seat, a support plate, a balancing weight, a base, a stop block and a rib plate, wherein the clamping jaw ring is connected with the upper part of the clamping jaw seat; the support plate is welded with the lower part of the clamping jaw seat; the lower end surface of the support plate is welded with the balancing weight and the stop block respectively; the upper part of the base is welded with the balancing weight and the stop block respectively; and the lower part of the seat is welded with the rib plate. The practical tricone bit dismantling device has the beneficial effects that firstly, the dismantling device is a welded assembly during normal use, and the dismantling device is simple in structure, excellent in rigidity and convenient to operate and use; and secondly, when three evenly-distributed clamping jaws are clamped inside the cones of a tricone bit, the tricone bit can be screwed off by utilizing a reverse rotation torque of a drilling machine power head, and therefore, the tricone bit can be rapidly dismantled or installed without manually shock-loosening a drill rod by tools such as special socket wrenches, so that the dismantling device is good in centering performance and capable of very conveniently positioning and dismantling the bit; and the auxiliary time of replacing a tricone bit spare part during drilling construction can be greatly shortened.
Description
Technical field
The utility model relates to a kind of provision for disengagement, and more specifically, it relates to a kind of practical tricone bit provision for disengagement.
Background technology
Tricone bit is one of drilling bit the most widely both at home and abroad, and it is wide to have a stratum of adaptation, and characteristics such as rate of penetration height are made of component such as cutting structure, bearing arrangement, locking element, oil storage sealing device, spray nozzle devices.
Tricone bit is under the effect of the pressure of the drill and drill string rotating, and tooth crushing and wedging rock produce certain slip simultaneously and shear rock.When gear wheel rolls in the shaft bottom, tooth on the gear wheel impacts, is pressed into the stratum successively, and this effect can be with a bottom rock crushing part, and the shear action that slip brings by gear wheel reams another part rock residual between tooth simultaneously, make bottom rock broken comprehensively, well is extended.
The tricone bit huge market demand, rock bit is indispensable pith in oil, exploration, well and various probing industry.But at present the oil gas well that uses, water drilling rig are changed or during dismounting tricone bit Job Operations, main dependence manually dismantled tricone bit with box spanner, is easy to damage the drill rod thread part, uses inconvenient, its inefficiency causes drilling cost to raise.Therefore design and a kind ofly can install and remove the rock bit instrument fast, and this instrument is fixed on the drilling machine platform, utilize drill power head main shaft counter-rotating torque just can change or dismantle the demounting tool of tricone bit fast, thereby reduce drill bit parts replacement or take-down time greatly, reduce drilling cost, improve construction operation efficient.For this reason, many manufacturers and knowledgeable people research and develop at the problems referred to above, but do not have desirable product to emerge in market so far as yet.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, provide a kind of simple and reasonable, use reliable, without hand tools such as box spanners, just can realize the practical tricone bit provision for disengagement of dismounting.
The purpose of this utility model is achieved through the following technical solutions.This practical tricone bit provision for disengagement, it comprises jaw circle, jaw seat, gripper shoe, balancing weight, base, block and gusset, jaw circle and jaw seat top are welded together, gripper shoe and jaw seat bottom are welded together, the lower surface of gripper shoe is welded together with balancing weight and block respectively, and the top of base bottom and gusset welded together with balancing weight and block, base respectively welds together.
As preferably: described jaw circle is provided with three uniform jaws, is stuck in the tricone bit gear wheel during three jaws work.
As preferably: be provided with the water hole that has certain pressure when guaranteeing to return slurry in the pipe in the middle of described gripper shoe and the gusset.
As preferably: described base is positioned in the drilling machine platform, and jaw seat and base all adopt thick-walled pipe to make.
As preferably: described block is the fan-shaped platform structure that plays the role of positioning.
The beneficial effects of the utility model are: the one, and practical tricone bit provision for disengagement is when normal the use, and this demounting tool integral body is the soldering group component, and simple in structure, good rigidly is easy for operation.The 2nd, when three uniform jaws are stuck in the tricone bit gear wheel, utilize drill power head counter-rotating torque that tricone bit is backed out, do not use special hand tools such as box spanner manually to shake loose drilling rod operation, quick-detach or tricone bit is installed soon just, so drill bit dismounting, the centering performance is good, the location, dismounting is very convenient, can not use just quick-detach soon of hand tool, can significantly reduce the non-cutting time of changing the tricone bit spare part in the drilling construction, effectively reduce drilling cost, enhance productivity.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further.Though the utility model will be described in conjunction with preferred embodiment, should know, do not represent that the utility model is limited among the described embodiment.On the contrary, the utility model will be contained alternative, modified and the equivalent in the scope of the present utility model that can be included in attached claims restriction.
Extremely shown in Figure 7 as Fig. 1, be specific embodiments of the present utility model, integral body is the weldment structure, be fixed on the drilling machine platform, it comprises jaw circle 1, jaw seat 2, gripper shoe 3, balancing weight 4, base 5, block 6 and gusset 7, jaw circle 1 is welded together with jaw seat 2 tops, gripper shoe 3 is welded together with balancing weight 4 and block 6 respectively with lower surface welded together, gripper shoe 3, jaw seat 2 bottoms, and the top of base 5 welds together with balancing weight 4 and block 6 bottom and gussets 7 welded together, base 5 respectively.Described jaw circle 1 is provided with three uniform jaws 8, is stuck in the tricone bit gear wheel, utilizes drill power head counter-rotating torque to change or the dismounting tricone bit, is made by superior alloy steel; Gripper shoe 2 and the gusset 7 middle water holes 9 that are equipped with have certain operating pressure in the pipe when guaranteeing to return slurry; Block 6 plays the role of positioning, and prevents the provision for disengagement rotation; Balancing weight 4 plays the counterweight effect; Gripper shoe 3 plays a supportive role with gusset 7; Jaw seat 2 and base 5 are made by thick-walled pipe.Described base 5 is positioned to have certain intensity in the drilling machine platform.
