Abstract

Rod for oilfield polished rod eye MC nylon movable pulley component, relates to the structure of the roller of oilfield polished rod hanger, and comprise two movable pulley of being cast by MC nylon material, the periphery of each movable pulley respectively radial direction arranges steel wire rope groove; Same connecting axle is placed in two movable pulley, connecting axle is arranged two positive stop lug boss, two positive stop lug boss are arranged between two movable pulley, each movable pulley respectively and arrange two bearings and a sleeve pipe between connecting axle, each sleeve pipe is separately positioned between corresponding two bearings, the outside of each bearing arranges bearing cover respectively, and each bearing cover is connected by screw with corresponding movable pulley respectively.The present invention by above design, then with polished rod, polished rod eye with the use of, structure is more reasonable.And owing to adopting the casting of MC nylon to form, therefore very light weight, non-corrosive, corrosion-resistant, nylon wheel has protective effect to wire rope, life-span of nylon wheel and wire rope be with the first six doubly more than.

Description

Rod for oilfield polished rod eye MC nylon movable pulley component
Technical field
The present invention relates to the structure of the roller of oilfield polished rod hanger.
Background technology
Rod for oilfield polished rod eye MC nylon movable pulley, material is in the past all QT700, and unreasonable due to structure, the shortcoming of this pulley clearly, pulley weight is very large, and the weight of assembly pulley itself just have impact on lifting capacity, is secondly that steel work pulley is muddy through can't stand rain of exposing to the weather, easily get rusty, moreover how long have more than is needed the friction of wire rope and steel wheel is very serious, wire rope is fracture just, and potential safety hazard is large.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of rod for oilfield polished rod eye MC nylon movable pulley component of rational in infrastructure, long service life is provided.
The object of the present invention is achieved like this: rod for oilfield polished rod eye MC nylon movable pulley component, and comprise two movable pulley of being cast by MC nylon material, the periphery of each movable pulley respectively radial direction arranges steel wire rope groove; Same connecting axle is placed in two movable pulley, connecting axle is arranged two positive stop lug boss, two positive stop lug boss are arranged between two movable pulley, each movable pulley respectively and arrange two bearings and a sleeve pipe between connecting axle, each sleeve pipe is separately positioned between corresponding two bearings, the outside of each bearing arranges bearing cover respectively, and each bearing cover is connected by screw with corresponding movable pulley respectively.
The present invention by above design, then with polished rod, polished rod eye with the use of, structure is more reasonable.And owing to adopting the casting of MC nylon to form, therefore very light weight, nylon material non-corrosive, corrosion-resistant, nylon wheel has protective effect to wire rope, life-span of nylon wheel and wire rope be with the first six doubly more than.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present invention.
Fig. 2 is the structural representation of Fig. 1 use occasion.
Detailed description of the invention
As shown in Figure 1, be rod for oilfield polished rod eye MC nylon movable pulley component, comprise two movable pulley 1 of being cast by MC nylon material, the periphery of each movable pulley 1 respectively radial direction arranges steel wire rope groove 7.Same connecting axle 4 is placed in two movable pulley 1, connecting axle 4 is arranged two positive stop lug boss 4-1, two positive stop lug boss 4-1 are arranged between two movable pulley 1, each movable pulley 1 respectively and arrange two bearings 5 and a sleeve pipe 2 between connecting axle 4, each sleeve pipe 2 is separately positioned between corresponding two bearings 5, the outside of each bearing 5 arranges bearing cover 6 respectively, and each bearing cover 6 is connected by screw 3 with corresponding movable pulley 1 respectively.
As shown in Figure 2, polished rod 11 is set on the connecting axle 4 between two movable pulley 1, polished rod 11 is arranged bearing 9, bearing cover 10 and footstock 8, and footstock 8 is arranged between two positive stop lug boss 4-1, and bearing cover 10 is arranged on the outside of bearing 9.
