Effect.
Sliding block 8 is made of high-abrasive material, reduces the abrasion reduced while friction to guide rail, coaster and derrick guide rail by
Conventional rigid collision is changed to elastic collision, can so improve the service life of guide rail and coaster.
The operation principle of the utility model device is, top drive coaster along derrick upper/lower guide run when, particularly run to
Derrick stage casing switch tracks position when because the influence of the factors such as foozle can produce strong shock and vibration, at present it is existing this
Sliding block is only fixed by bolts on coaster by class patent, it is impossible to solve top drive in running the vibration that brings of rigid contact and
Shock problem.This patent adds combination disk spring inside the sliding block of top drive coaster and the rigid contact of sliding block and guide rail is changed into bullet
Property contact, this elastic deformation and spring rate are met the normal work needs that top is driven, can effectively solved by using this technology
Certainly above mentioned problem, and push up to drive in operation process in oil field and be verified and approve.
The course of work of the utility model device is reference picture 3- Fig. 5,
When the regional extent that 10 are located at lower guideway 14 is driven on top, three pairs of sliding blocks 8 on left slider bearing 2 are in each combination dish
Contacted all the time with lower guideway 14 in the presence of spring 4, the sliding block 8 in upper and lower running of top drive 10 compresses combination disk spring 4 with automatic
Caused straightness error in guide rail manufacturing process is adapted to, while provides top to reaction force caused by sliding block by disc spring and drives 10
Required reaction torque, when the decrement of combination disk spring 4 reaches δ, sliding block 8 is contacted with left slider bearing 2, and combination disk spring 4 is carried to
Up to maximum, unnecessary load transmission to left slider bearing 2, ensure that combination disk spring 4 is in rational deformation range, meet to use
Life requirements；
When the regional extent that 10 are located at upper rail 13 is driven on top, three pairs of sliding blocks 8 in right slider bearing 3 connect with upper rail 13
Touch, operation principle is same as above.
Because sliding block 8 is being provided at both ends with chamfering, it can so ensure that top drives 10 and runs to upper rail 13 by lower guideway 14
Or excessive impact, smooth transition to another section of guide rail will not be produced during by upper rail 13 running to lower guideway 14
On.
