Abstract
The utility model relates to the field of blocks of oil workover rigs, in particular to a self-centering block of an oil workover rig. The self-centering block comprises a block frame, axles and wheels, and is characterized in that side swing wheel supports are arranged on two sides of the block frame, at least two side swing wheel supports are arranged on one side of the block frame, side swing shafts are arranged at ends of the side swing wheel supports, and side swing wheels are arranged on the side swing shafts and are bearings which are fixed at ends of the side swing shafts through end caps. Compared with the prior art, the self-centering block of the oil workover rig has the advantages of simple structure, compactness, reliability and high practicality; a hook block assembly runs along groove steel slipways by the aid of the block, so that the hook block assembly can stably and safely run and can be well centered with the center of a well mouth; and the block can be applicable to workover rigs in different models.
Description
Technical field
The utility model relates to petroleum well servicing rig coaster field, and is particularly a kind of from centering petroleum well servicing rig coaster.
Background technology
During the well site of oil field operation, the landing that hoists of hook block is freely, hook block is limited in the slideway moves by setting up tackle arrangement, but when being connected with coaster, hook block can not keep good centering, aim at more exactly well head in order to make hook, must increase centering adjusting device, just can make hook be limited in operation in the slideway, increase the security reliability of hook operation.
Summary of the invention
The purpose of this utility model provides a kind of from centering petroleum well servicing rig coaster, makes hook block inner at slideway by coaster walking, makes the safety that operates steadily of hook block, and can be well and the well head center.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind ofly comprise apparatus for suspension, axletree and wheel from centering petroleum well servicing rig coaster, the apparatus for suspension both sides are respectively equipped with the side-sway wheel support, and apparatus for suspension one side is minimum to arrange two side-sway wheel supports, and side-sway wheel support end is provided with the side-sway axle, and the side-sway axle is provided with the side-sway wheel.
Described side-sway wheel is bearing, and bearing is fixed in the side-sway axle head by end cap.
Compared with prior art, the beneficial effects of the utility model are: 1) overall structure is simple, solid reliable, practical; 2) hook block along channel-section steel slideway walking, makes the safety that operates steadily of hook block by coaster, and can be well and the well head center; 3) applicable to the workover rig coaster of multiple different model.
