Abstract
The utility model belongs to the technical field of lifting system components required for oil and gas well drilling devices and particularly relates to a novel lifting ring for oil and gas well drilling. The novel lifting ring comprises an inverted U-shaped lifting ring parent body (1), the lifting ring parent body (1) comprises a concave structure located in the middle and connecting bodies located on two sides, the connecting bodies are provided with notches, lifting ring pins (2) are inserted into the notches and are fixedly welded to the connecting bodies, and lifting rings (4) are arranged at the bottoms of the lifting ring pins (2). According to the lifting ring for well drilling, by designing the lifting ring parent body (1) and the lifting ring pins (2) into an inserted and fixedly welded mode, the problems of high cost and high rejection rate which are caused by integrated forging forming and bending in the prior art are solved, whole stress effect of the lifting ring for well drilling is optimized, and the using requirements under large lifting load conditions are met.
Description
Technical field
The utility model belongs to the required Hoisting System component technology of oil and gas well drilling device field, relates in particular to a kind of oil and gas well drilling drop handle.
Background technology
Drop handle is vitals indispensable in the oil and gas well drilling Hoisting System, and the forging plane of existing drop handle is circular section and two kinds, long cross section.The phenomenon that the circular section drop handle easily causes stress to concentrate, and for the long cross section drop handle of one, due to integral body employing forging molding, when this drop handle forges because drop handle length is long, have higher requirement for processing, can not carry out effective cost control, percent defective also is in 50% left and right.Conventional drop handle distribution of force is inhomogeneous, causes usually that local pressure is excessive, stress is concentrated, thereby has greatly limited the scope of application of drop handle.
The utility model content
The utility model provides for solving the technical problem that exists in known technology the drilling well drop handle that a kind of whole stressed effect is good, be convenient to process, and satisfies large instructions for use and the simplified processing process that promotes load.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of nonpetroleum gas drilling comprises inverted U-shaped drop handle parent with drop handle, described drop handle parent comprises the concave structure that is positioned at the middle part and the connector that is positioned at both sides, be equipped with notch on described connector, all be inserted with the drop handle pin in described notch, described drop handle pin and the welding of described connector are affixed; Bottom at described drop handle pin is provided with drop handle.
Advantage of the present utility model and good effect are: drilling well of the present utility model is with the form of drop handle by drop handle parent and drop handle pin are designed to peg graft and are welded and fixed, solved expensive, the high percent defective problem brought of the form of bending again of one forging molding in the prior art, optimize the whole stressed effect of drilling well with drop handle, satisfied the large instructions for use that promotes in load condition.
Preferably: the cross section of described drop handle parent is rectangle.
Preferably: the material of described drop handle parent is low-alloy structural steel.
Preferably: the cross section of described drop handle pin is rectangle.
Preferably: offer the pin-and-hole that aligns on described connector and described drop handle pin, be inserted with bearing pin in this pin-and-hole.
Preferably: also be provided with the ring ear on the outer wall of described drop handle pin.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 be in Fig. 1 A-A to sectional view.
In figure: 1, drop handle parent; 2, drop handle pin; 3, ring ear; 4, drop handle.
The specific embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
See also Fig. 1 and Fig. 2, the utility model comprises inverted U-shaped drop handle parent 1, and its cross section is that rectangle, material are low-alloy structural steel, comprises the concave structure that is positioned at the middle part and the connector that is positioned at both sides.Wherein concave structure is used for being connected with hook tourist bus lower end connection, and when working, all load all act on this concave structure with drop handle in this drilling well.
Be equipped with notch on connector, all be inserted with the drop handle pin 2 that the bottom is provided with drop handle 4 in notch, drop handle pin 2 adopts the mode of welding affixed with connector.In this example, in order to optimize whole stressed effect, the cross section of drop handle pin 2 also is set to rectangular in form.
In order to promote the effect that is connected of drop handle pin 2 and drop handle parent 1, offer the pin-and-hole that aligns on connector and drop handle pin 2, be inserted with bearing pin in this pin-and-hole.Specifically add man-hour, can first adopt bearing pin that drop handle pin 2 and connector are fixed, weld again afterwards.
Drilling well in the present embodiment is welded to connect afterwards with the drop handle forging molding that can distribute again.The material of drop handle parent 1 is low-alloy structural steel, and this kind low-alloy structural tensile strength of steel is large, forgeability good, welding performance is good, and under low temperature condition, ballistic work is high, can satisfy in low temperature (35 ℃) situation and use.Therefore, existing its hot strength of drop handle of this drop handle can improve that 25% left and right is improved in 20% left and right, ballistic work, the drop handle cost reduces by 50% left and right.In the situation that satisfy same load and, the each several part performance has all obtained optimization.
The drop handle structure that the utility model is designed can be applied on the drop handle of conventional drilling water tap, is particularly useful in the drop handle of top-drive drilling is used.
