Summary of the invention
The many drawbacks of middle existence of making a trip for on-the-spot double, two elevators and the phenomenon extremely required great effort during on-site with the instrument of artificial more mobile heavinesses, the purpose of the present invention has aimed to provide the elevator of a kind of suspension ring easy to hang, move the work-saving device of weight, this device make use of and combines with steel ball at a concentric cylinder inner spring, spring force is more than the weight of elevator and cumbersome tools, the principle that steel ball rolling resistance is little lifts certain height empty elevator and cumbersome tools spring force, because only having the steel ball and earth surface that under concentric cylinder inner spring, ejection tool body outer rolling resistance is little when the mobile empty elevator lifted by spring force and cumbersome tools, manually very easily move elevator and cumbersome tools。When empty elevator sits on well head because drilling tool weight is far longer than the spring force lifting elevator in elevator concentric column body, spring is made the elevator height sitting drilling tool set back by compression, the high official post suspension ring so caused because of the suspension ring amplitude of oscillation in elevator ear not the problem of easy pull on be addressed, be substantially reduced and do not enter, because suspension ring are easy to hang, the single-ring accident caused in wellhead lifting-clamping ear。Also utilize the principle that under concentric cylinder inner spring, steel ball can roll in any direction and frictional resistance is little and greatly reduce the post workman labor intensity when well head is moved cumbersome tools as Lifting clamp and uses artificial more mobile cumbersome tools on any building site。
It is an object of the invention to so to complete:
A kind of elevator of suspension ring easy to hang, move the work-saving device of weight, it is arranged on elevator and the bottom of heavy industry tool, main by jump ring, ball rail righting seat, steel ball, ball rail support guide seat, spring, spring guide holder and tool body composition, jump ring is stuck in the jump-ring slot that tool body is opened, withstand on the bottom of ball rail righting seat, steel ball is limited between ball rail righting seat and ball rail support guide seat, part sphere exposes outside tool body under the elastic force effect of spring, spring supporting is between ball rail support guide seat and spring guide holder, spring rod guide supports is in tool body。
Advantages of the present invention and generation provide the benefit that:
1, the present invention just can repair at the scene, safeguards and change accessory, and cost is low, have the advantage commonly used。
2, the part steel ball that the present invention ejects because of concentric cylinder inner spring under elevator goes out outside tool body, sky elevator is made to have been lifted certain altitude, the height lifting of empty elevator hanger, compensate for the difference in height that the discrepancy in elevation caused when the middle extension that makes a trip plucks suspension ring causes because of the suspension ring amplitude of oscillation, make suspension ring pluck toward easy to hang in elevator ear, reduce suspension ring and do not hang the single-ring accident risk that driller's maloperation causes in elevator ear。
3, the present invention is because of part steel ball that below elevator and cumbersome tools, only concentric cylinder inner spring ejects and earth surface, the reduction of rolling and frictional resistance, be substantially reduced labor intensity when post workman moves instrument, avoiding simultaneously by hand the dynamic elevator of tool holder and cumbersome tools time skid and make post workman fall down the generation of fish accident in injured danger and well。
