Abstract
A hook of a traveling block is used for petroleum drilling and remedial work. An original casting hook body and an original casting hook cylinder of the hook of the traveling block is improved into a forging hook body and a forging hook cylinder, in other words, the hook body and the hook cylinder are formed by conducting thermal treatment, flaw detection and machining on forged forgings, and main bearing parts of the hook of the traveling block are all made of the forgings, wherein the nominal load of the hook of the traveling block is larger than 900KN. Due to the fact that the general mechanical performance of the forgings is one grade higher than that of castings, the using performance and the safety performance of the hook can be greatly improved, whole and full working condition safe reliability of the hook of the traveling block is improved, the hook can be more suitable for the low-temperature environment, and the quality grade of the hook is greatly improved.
Description
Technical field
The utility model relates to the hook block that a kind of oil drilling and well workover are used, and particularly a kind of nominal load is greater than the forging coupler body of 900KN and the hook block of hook cylinder.
Background technology
Key equipment when hook block belongs to oil drilling and well workover in its Hoisting System, its effect is when drilling well and workover treatment, to promote main load.Due to particularity and the importance of working condition, its comprehensive mechanical performance is had to very high requirement, especially need absolute security performance.The nominal load of in industry using is at present greater than in the hook block of 900KN, what the coupler body in its main bearing member and hook barrel part adopted is cast member, due to the comprehensive mechanical performance poor controllability of foundry goods self, can not meet security performance needs completely, reliability is not high, especially under ultra-low temperature surroundings, has potential safety hazard.
Summary of the invention
The utility model is to provide the safe hook block that a kind of main bearing member is all forging, its nominal load is greater than 900KN, the key problem in technology solving is mainly original foundry goods coupler body hook cylinder to be improved to and to forge coupler body hook cylinder, the source that is coupler body hook barrier part is by passing through the forging forging again through heat treatment, carrying out flaw detection and machining, thereby makes the main bearing part in hook block all use forging.Because the comprehensive mechanical performance of forging itself exceeds a class than foundry goods, institute so that its functional performance and safety be greatly improved, thereby the overall full working condition safety reliability of having improved hook block product, more can be applicable to low temperature environment, has greatly promoted the total quality grade of product.
Accompanying drawing explanation
Take YG225 hook block as example, this accompanying drawing is described further below.
This accompanying drawing is half section structure chart of the present utility model.The utility model is mainly comprised of coupler body (1), locking device (2), lifting lug (3), coupler body fulcrum post (4), shank (5), thrust bearing (6), hook cylinder (7), spring (8), side plate (9), hook cylinder fulcrum post (10), assembly pulley (11), pulley spindle (12) and tourist bus guard shield (13).Wherein coupler body (1) and hook cylinder (7) are forge pieces.Coupler body (1) is connected with shank (5) by coupler body fulcrum post (4), shank (5) acts on load on hook cylinder (7) by spring (8) and thrust bearing (6), hook cylinder (7) is connected with side plate (9) by hook cylinder fulcrum post (10), side plate (9) is connected with pulley spindle (12), pulley spindle (12) acts on load on assembly pulley (11), tourist bus guard shield (13) is fixed on side plate (9), locking device (2) and lifting lug (3) are connected on coupler body (1).Assembly pulley (11) can be in the upper rotation of pulley spindle (12).
The specific embodiment
Below in conjunction with accompanying drawing, take YG225 hook block as example, utility model is described further:
The utility model is mainly comprised of coupler body (1), locking device (2), lifting lug (3), coupler body fulcrum post (4), shank (5), thrust bearing (6), hook cylinder (7), spring (8), side plate (9), hook cylinder fulcrum post (10), assembly pulley (11), pulley spindle (12) and tourist bus guard shield (13).Wherein coupler body (1) and hook cylinder (7) are forge pieces.Coupler body (1) is connected with shank (5) by coupler body fulcrum post (4), shank (5) acts on load on hook cylinder (7) by spring (8) and thrust bearing (6), hook cylinder (7) is connected with side plate (9) by hook cylinder fulcrum post (10), side plate (9) is connected with pulley spindle (12), pulley spindle (12) acts on load on assembly pulley (11), tourist bus guard shield (13) is fixed on side plate (9), locking device (2) and lifting lug (3) are connected on coupler body (1).Assembly pulley (11) can be in the upper rotation of pulley spindle (12).
Coupler body (1) and hook cylinder (7) are forge pieces, after forging, heat treatment, machining and nondestructive testing, to be assembled into water tap with selected metal material, make these two crucial bearing parts have high-strength comprehensive mechanical performance, consequently the main bearing part in hook block is all used forging.Thereby make the global reliability of hook block product and security performance obtain the raising of essence.
