Abstract
The utility model provides a piston-type lubricating device for lubricating a steel wire rope of a beam-pumping unit. The piston-type lubricating device comprises a walking beam, a horsehead and the steel wire rope, wherein the horsehead is mounted at one end part of the walking beam; the upper end of the steel wire rope is fixed on the horsehead. The piston-type lubricating device is characterized in that an oil cylinder supplying a lubricant to a fixed point of the steel wire rope through a piston mouth is arranged on the rear side of the horsehead; the cylinder body of the oil cylinder is fixed on the walking beam through a support piece; a cavity for accommodating a rolling body is arranged in the piston rod of the oil cylinder; the oil cylinder is filled with the lubricant. After the adoption of the piston-type lubricating device, no power device is needed; the piston-type lubricating device is simple and effective, does not need a control device, and has a low failure rate and a long maintenance-free period. According the utility model, defects in the prior art are avoided, manual aloft working is effectively avoided, equipment safety and personnel safety are ensured, the service life of the steel wire rope is prolonged, and the oil extraction efficiency of an oil extraction machine is increased.
Description
Technical field
Belong to beam pumping unit technical field, specifically a kind of lubricating fitting with self-lubricating effect of non-power.
Background technique
Beam pumping unit is that a large amount of use a kind of of oil field operation have a bar class oil production equipment, has the features such as said device features rational structure, stable working, noise are little, convenient operating maintenance.Wire rope connects pumping unit horsehead and sucker rod, and industry slang is referred to as " hair plait ".While working due to wire rope, always in outdoor rugged environment, and bear compared with heavy load, so wire rope is often because corrosion, disconnected strand, fracture cause huge economic loss and security incident.For fear of occurring with minimizing accident, often need more change steel rope, the waste plenty of time.Traditional lubricating system is artificial coating butter, during operating cost, effort; The more important thing is that workman's high-lift operation has very large potential safety hazard and risk; Stop for a long time well and also can cause pumping well sand card, wax card and gas lock.
Now, most of pumping unit lubricating fittings all organic fuel tank, control switch, oil circuit main pipe line and oil circuit divide pipeline to form, and wherein sump is installed in the rear portion of walking beam; Also include control valve, oil circuit bus, oil circuit branch means, many oil circuit separated times, one end of oil circuit bus communicates with sump by control valve, and the other end of oil circuit bus connects each oil circuit separated time by oil circuit branch means; The oil outlet end of oil circuit separated time is positioned at the top of every hair plait of pumping unit, and this device has good lubrication effect.But this method is very easy to break down, as pipeline blockage, break, control gear fault, and structure is with respect to complexity.
Model utility content
In order to solve the deficiencies in the prior art, the utility model provides a kind of beam pumping unit wire rope that is simple and easy to safeguard to infiltrate lubricating fitting, is a kind of self-lubricating device of non-power.
The utility model solves the technological scheme that its technical problem adopts: a kind of piston type lubricating fitting that beam pumping unit wire rope is lubricated, comprise walking beam, horse head and wire rope, wherein said horse head is arranged on the end of walking beam, the upper end of described wire rope is fixed on horse head, it is characterized in that, at described horse head rear side, be provided with one to the oil cylinder to wire rope immovable point supplying lubricating oil by piston mouth, the cylinder body of described oil cylinder is fixed on walking beam by supporting element, and in the piston rod of described oil cylinder, be provided with a cavity that accommodates rolling element, in described oil cylinder, be full of lubricant oil.
Described rolling element is a steel ball.
In described piston rod cavity, outer end is provided with a groove that steel ball is limited to initial position.
In the scope of the angle of described oil cylinder and walking beam in ± 15 degree.
Described oil cylinder and walking beam be arranged in parallel.
The beneficial effects of the utility model are: adopt this device lubricated, and without any need for power plant, simply effective, do not need control gear, rate of breakdown is extremely low, and the non-maintaining cycle is long.Not only avoid the defect of prior art, effectively avoided artificial high-lift operation, guaranteed equipment and personal safety; Extend the working life of wire rope, improved the oil recovery efficiency of oil pumping unit simultaneously.
Accompanying drawing explanation
Fig. 1 is structure principle chart of the present utility model.
Fig. 2 is the schematic diagram of self-lubricating device.
In figure: 1 horse head, 2 wire rope, 3 oil cylinders, 4 lubricant oil, 5 supports, 6 beads, 7 piston rods, 8 walking beams.
Embodiment
As shown in Figure 1 to Figure 2,
A steel wire rope of oil pumping unit lubricating fitting, comprises walking beam 8, horse head 1 and wire rope 2, and wherein horse head is arranged on the end of walking beam, and the upper end of wire rope is fixed on horse head, belongs to the horse head structural style of existing pumping unit.Improvement is, increases a set of self-lubricating device, comprises oil cylinder 3, lubricant oil 4, support 5, bead 6, piston rod 7, and the cylinder body of described oil cylinder is welded on walking beam by support 5.At horse head 1 rear side, be provided with one to the oil cylinder to wire rope immovable point supplying lubricating oil by piston mouth, in this oil cylinder, be full of lubricant oil, and extrude lubricant oil by the motion of piston rod.
Piston rod 7 is hollow structures, bead 6 is placed in the cavity of piston rod, and can Free-rolling, along with the swing of walking beam, bead 6 rolls and knocks piston rod 7 under gravity field effect, in piston rod 7 inner chambers, outer end is provided with a groove and bead 6 is carried out spacing, makes it temporarily to be located, and forms the initial position of a high point, while only having walking beam to reach certain angle of inclination, while reaching capacity, bead just can fall, and plays the effect of time delay.
The potential energy difference that the utility model produces while utilizing walking beam to swing, is converted into kinetic energy by the gravitational potential energy that bead 6 is fallen to producing, and bead is knocked and promote piston to produce fine motion, squeezes out parts of lubricating oil.Then again because self gravitation and the effect of inertia of lubricant oil can lubricate hair plait, form self-lubricating effect.It is a kind of lubricating structure of non-power.
Embodiment recited above is described preferred implementation of the present utility model; not scope of the present utility model is limited; do not departing under the prerequisite of the utility model design spirit; relevant technical staff in the field, to various distortion of the present utility model and improvement, all should expand in protection domain as determined in the utility model claims.
