Abstract
The utility model relates to a protection cap for disassembling and assembling traveling block elevator link in petroleum drilling. The technical scheme is that the protection cap mainly comprises a big head, an outer conical face, a small head, an internal thread and a thread undercut; the internal thread is coincident with an external thread of the traveling block elevator link, inside which is provided with the thread undercut, and used for being connected with the thread of the traveling block elevator link and screwed by a pipe wrench; for the protection cap for disassembling and assembling traveling block elevator link, a section of round steel of which the outer diameter is equal to that of the working face of the traveling block elevator link is made into a cone type; the small head is made into a hexagonal nut, in which the materials are removed to reduce the weight; the big head is lathed with the thread undercut and the internal thread; the outer conical face of the utility model is quenched and hardened by the processing technology. The protection cap for disassembling and assembling traveling block elevator link has the beneficial effects of having no damage to the thread of the traveling block elevator link when disassembled, fast and easy installation, saving time, shortening the mine construction cycle and improving the economic benefits.
Description
Technical field
The utility model relates to a kind of oil drilling and guides protective cap with the demolition, installation of tourist bus suspension ring pin, the hook that is hung below the tourist bus when energy safety, quick demolition, installation drillng operation.
Background technology
The demolition, installation hook is the important ring in the drilling well demolition, installation device procedures.1, hook is torn at the scene open at present: hook is transferred to correct position, fastened steel wire loop and made the moving puffer of electricity consumption (gas) sling, set upright the hook suspension ring, the back uses cooperations such as sledgehammer, crowbar to pull down the connecting pin of tourist bus suspension ring and hook drop handle, tourist bus suspension ring pin under the dismounting is owing to live through knocking (or prized by crowbar) like this, in operating process, slip up, can smash tourist bus suspension ring pin screw thread or land and break tourist bus suspension ring pin screw thread, cause to be difficult to dismounting next time; 2, the on-the-spot at present hook of installing: make the moving puffer of electricity consumption (gas) set upright the hook drop handle, open the tourist bus suspension ring, transfer tourist bus and cooperate and push away tourist bus the hook drop handle is entered in the suspension ring of tourist bus, under the situation that nothing compresses, buckle well the tourist bus suspension ring, tourist bus suspension ring pin is put into installing hole, use sledgehammer with its pound into, worn nut, first-class safety plug ..., difficulty when this process narration is done easily, because used hook block, the hook that in use bears carries usually more than 1000kN, so used tourist bus tends to take place a little distortion, causes tourist bus suspension ring pin-and-hole can produce to a certain degree dislocation, cause tourist bus suspension ring pin to penetrate difficulty, waste time and energy.
Summary of the invention
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of tourist bus suspension ring pin demolition, installation guiding protective cap is provided, and makes in the drillng operation demolition, installation hook rapider safer, and can protect tourist bus suspension ring pin screw thread.
Its technical scheme is: mainly be made up of stub end, male-tapered face, little head end, internal thread, Gewindefreistiche, described internal thread conforms to tourist bus suspension ring pin external screw thread button-type, the inboard of internal thread is provided with Gewindefreistiche, be connected with tourist bus suspension ring pin threaded portion during use, use pipe wrench that it is tightened; Described tourist bus suspension ring pin demolition, installation guiding protective cap is that one section external diameter is tapered with the round steel shape fabricating that tourist bus suspension ring pin work plane external diameter equates, and little head end is made into the hexagonal (hexagon)nut body, the inner material that removes is to alleviate component, stub end thread cutting escape with the identical internal thread of tourist bus suspension ring pin external screw thread button-type, by processing technology the utility model male-tapered face is hardened; For guaranteeing reliability of the present utility model, described tourist bus suspension ring pin demolition, installation guide the stub end external diameter and the tourist bus suspension ring pin body equal diameters of protective cap, and the length of internal thread is greater than tourist bus suspension ring pin external thread length 3～5mm.
The beneficial effects of the utility model are: after using this use novel, dismounting tourist bus suspension ring pin down can damaged screw, and is easy fast during installation, can save time, and shortening well construction period, increases economic efficiency.
Description of drawings
Accompanying drawing 1 is a profile schematic diagram of the present utility model;
Accompanying drawing 2 is the structural representations after the utility model complete section;
Accompanying drawing 3 is assembling explosive views of the utility model and tourist bus suspension ring pin;
Accompanying drawing 4 is assembling drawings of the utility model and tourist bus suspension ring pin
Among the last figure: stub end 1, male-tapered face 2, microcephaly hold 3, internal thread 4, Gewindefreistiche 5.
The specific embodiment
1-4 in conjunction with the accompanying drawings is further described the utility model:
The utility model mainly by stub end 1, male-tapered face 2, microcephaly hold 3, internal thread 4 and Gewindefreistiche 5 form.
Manipulate method: the tourist bus suspension ring pin external screw thread that internal thread on the utility model stub end 14 and drilling well are used is connected and tightens, and uses pipe wrench to block the microcephaly and holds 3 to carry out the utility model and tourist bus suspension ring pin fastening.Fastening back tourist bus suspension ring pin demolition, installation guiding protective cap and tourist bus suspension ring pin are assembled into a big pin body of taper, can carry out dismounting.When tourist bus suspension ring pin is installed, the big pin body of taper (tourist bus suspension ring pin and the utility model) that is assembled into is penetrated in the installing hole, use sledgehammer with its pound into, after treating that tourist bus suspension ring pin is in place, using pipe wrench that the utility model is dismantled from the screw thread place takes off, install the tourist bus suspension ring and lock solid nut, promptly finish the Fast Installation of tourist bus suspension ring pin; During dismounting tourist bus suspension ring pin; unload the clamp nut of tourist bus suspension ring pin; the utility model and tourist bus suspension ring pin are assembled by screw thread; use sledgehammer to beat the utility model microcephaly then and hold 3; its integral body can be pounded out; deposit, in order to installing and using next time, this moment, the utility model played the function of protecting sleeve for thread.
