Description
Technical field
The present invention relates to drilling rod and carry leading-in device, be specifically related to avoid the leading-in device of carrying coming off.
Background technology
At PETROLEUM PROCESSING field elevator as an important tool in drilling equipment utensil, in landing drilling tool, undertaking and connecting and the task of throwing off drilling tool, job safety accident on the tower that labour intensity unattended on tower in order to realize, that alleviate workman, reduction bring thus, requires easy to operate and safe and reliable.Although tiltedly de-formula elevator has been realized on tower automatic trip from drilling tool, aspect unattended on tower, play great role, but reach convenient and practical, safe and reliable, realize on tower unattendedly completely, remain a great problem of probing in industry, still need scientific and technical personnel's persevering endeavors.Tangling water tap in elevator draw-in groove part hangs surely, mention after kelly puts in place, kelly bottom joint is pitched with fork, loosen again wire rope, elevator under Gravitative Loads, hang up from the fire hose crown automatic trip from, in this process, elevator very easily departs under self-gravity action, brings potential safety hazard.And elevator be not suspended to position, hang over draw-in groove port part landing also easily occurs, this is because draw-in groove mouth is oblique shape face because this position of long-term use is easy to wear, opening to be increased.
Summary of the invention
The present invention has overcome the deficiencies in the prior art, provide and avoid the leading-in device of carrying that comes off, the bayonet socket of set bolt and coupling is set on garter spring, allows garter spring removably connect, avoid this device in the time of hanging articles because Action of Gravity Field comes off, at the top of draw-in groove, groove is set simultaneously, tap top is hung and is seated on groove, avoid the wearing and tearing of draw-in groove mouth, reduce the risk of landing, reduce potential safety hazard, safety and reliability.
For solving above-mentioned technical problem, the present invention is by the following technical solutions: avoid the leading-in device of carrying that comes off, comprise elevator body and drop handle, drop handle is arranged on the top of elevator body, also comprise thrust ball bearing, garter spring and draw-in groove, described thrust ball bearing is arranged on the top of elevator body; Described garter spring is enclosed within on elevator body and can on elevator body, slides up and down, and is also provided with set bolt at the top of garter spring; The bottom of described elevator body is provided with draw-in groove, is provided with groove at the top of draw-in groove, is also provided with at the inwall top of elevator body the bayonet socket mating with set bolt.This kind of automatic trip from elevator, in the time mentioning kelly, garter spring is pushed into elevator body top, when sealing with waste water pump leather cup, also by set bolt and bayonet socket coordinate realize fixing, avoid garter spring fall, thereby avoid elevator automatic trip from situation occur, use safety and reliability.
Described groove is car groove processed, and shoulder height scope is between 6-10mm.
Between described thrust bearing and elevator body, be bolted, on the screw rod of bolt, be also used in conjunction with nut.
The altitude range of described draw-in groove is between 25-35mm.And the height of groove step is between 6-10cm, the restriction top that is provided for of step hangs over slippage in lifting, but the degree of depth of step can not affect the operation of hanging into disengaging drilling rod latching connector.Also can avoid elevator not to be suspended to position, hang over draw-in groove port part, after long-term use, make these position wearing and tearing cause oblique shape and occur that the situation that water tap comes off occurs.
Described garter spring seals by waste water pump leather cup in moving up and down.
Described thrust ball bearing is positioned at circular-arc drop handle.
Compared with prior art, the invention has the beneficial effects as follows:
1, the top that is fixed on elevator body that garter spring of the present invention removably connects by being used in conjunction with of set bolt and bayonet socket, also have being used in conjunction with of waste water pump leather cup simultaneously, prevent that garter spring from departing from, avoid elevator in the time needing hanging articles and under the effect from gravity automatic trip from, use safety and reliability.
2, at the top of draw-in groove, groove is set, avoids occurring that elevator is not in the situation that being suspended to position, draw-in groove mouth is squeezed to wear and tear and is oblique shape, and occurs that top hangs over the situation of slippage in lifting, further improves the safety factor of use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure, Reference numeral is expressed as: 1, drop handle; 2, nut; 3, thrust ball bearing; 4, elevator body; 5, set bolt; 6, garter spring; 7, groove; 8, draw-in groove; 9, bayonet socket.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further elaborated, and embodiments of the invention are not limited to this.
Embodiment:
As shown in Figure 1, the present invention includes elevator body 4 and drop handle 1, drop handle 1 is arranged on the top of elevator body 4, also comprise thrust ball bearing 3, garter spring 6 and draw-in groove 8, described thrust ball bearing 3 is arranged on the top of elevator body 4, the altitude range of draw-in groove 8 is between 25-35mm, and garter spring 6 seals by waste water pump leather cup in moving up and down, and thrust ball bearing 3 is positioned at circular-arc drop handle 1.The garter spring 6 of the present embodiment is enclosed within on elevator body 4 and can on elevator body 4, slides up and down, and is also provided with set bolt 5 at the top of garter spring 6; The bottom of elevator body 4 is provided with draw-in groove 8, is provided with groove 7 at the top of draw-in groove 8, is also provided with the bayonet socket 9 mating with set bolt 5 at the inwall top of elevator body 4.The groove 7 of the present embodiment is car groove 7 processed, and shoulder height scope is between 6-10mm.Between thrust bearing 3 and elevator body 4, be bolted, on the screw rod of bolt, be also used in conjunction with nut 2.
In the time mentioning kelly, garter spring is pushed into elevator body top, when sealing with waste water pump leather cup, also by set bolt and bayonet socket coordinate realize fixingly, avoid garter spring to fall, then draw-in groove is entangled to the fire hose crown and hangs, mention after kelly puts in place, kelly bottom joint sticks in fork, then loosens wire rope, elevator under self-gravity action, hang up from the fire hose crown automatic trip from.In this process, garter spring is difficult for gliding, be not prone to elevator in the situation that not being suspended to position, draw-in groove mouth is squeezed to wear and tear and is oblique shape, and occur that top hangs over the situation of slippage in lifting, further improve the safety factor using, avoid elevator in the time of hanging articles, occur automatic trip from situation occur, use safety and reliability.
Just can realize as mentioned above this invention.
