Description
Technical field
The utility model is relevant for a kind of pin changer, is particularly to a kind of offshore platform that is applicable to and is used to change the quick changer of pin of the pin of steel wire operation instrument.
Background technology
At present, offshore oilfield has entered exploration and development stages, but because offshore platform is subjected to spatial constraints, the onshore oil field implement can't satisfy the needs of offshore platform operation mostly.And skid steel wire operation equipment can be used for offshore field formation testing production testing operation again as a kind of device that both can be used for land oil well underground work, and good application prospects has just been arranged.As everyone knows, skid steel wire operation equipment is a kind ofly to reach the operation that the steel wire operation instrument is operated by the raising and decentralizing of steel wire utilization machinery that is wrapped on the winch, its equipment is simple, in light weight, and easy operating, and can in time transmit the down-hole situation.
But, at sea during steel wire operation, inside has the steel wire operation instrument of spring lever, especially throw in catcher, after reusing several times, the aluminum safety shear pin between steel wire operation instrument inner/outer tube might be cut off, spring lever compression and the relative urceolus of cutting off back steel wire operation tool interior move inwards, the pin hole of inner/outer tube can produce dislocation, causes steel wire operation instrument cisco unity malfunction, just needs to change the pin of steel wire operation instrument this moment.
In the prior art, change that pin generally all needs to push or the spring lever that is connected with spring of the steel wire power tool inside that stretches, yet the tension force of steel wire operation tool interior spring is very big, can't finish near the one man operation, must many people assists just can finish the replacing operation of pin.Specifically be, as shown in Figure 1, at first need two human screwdrivers that three slips 55 ' of steel wire operation instrument 5 ' are firmly outwards other, slips 55 ' is ejected, the 3rd people screws in a screw rod 1 ' spring lever 51 ' of steel wire operation instrument 5 ' then, take pliers to clamp screw rod 1 ' again, pull at screw rod 1 ' and make outwards motion of spring lever 51 ', pin hole 521 ' up to the inner core 52 ' of steel wire operation instrument 5 ' aligns with the pin hole 531 ' of urceolus 53 ', just can take out the pin 54 ' of fracture, the pin that more renews.
Because the offshore platform working space is less at present, the pin that adopts many people to assist to change the steel wire operation instrument can not satisfy the demand of operation on the sea, and it is bigger that it changes technical difficulty, not only waste of manpower and time, and influence job scheduling, reduced the final economic well-being of workers and staff of operation, therefore be necessary to provide a kind of can be by the single pin changer that just can change pin on the steel wire operation instrument fast of operating.
The utility model content
The purpose of this utility model provides the quick changer of a kind of pin, the quick changer of this pin can be changed the especially pin of throw in catcher of steel wire operation instrument fast by the one man operation, has reduced unnecessary manpower and waste of time, accelerating construction progress improves final operation economic well-being of workers and staff.
Above-mentioned purpose of the present utility model can adopt following technical proposal to realize:
