Abstract
The utility model discloses a reliable balancing weight emergency brake of a steel rope pumping unit, wherein the balancing weight comprises a multiple-groove movable pulley, a sliding support, the emergency brake, a pulley base, a central spindle, a balance weight body and the like. The emergency brake comprises a central spindle nut, a vibration damping or pressure spring, a spring guide sleeve, a brake connecting rod, a guide block, a push rod, a guide groove, a guide shaft and the like. The emergency brake is arranged between the pulley support and the balance weight body, and the three parts are integrated into a whole. The emergency brake is used for preventing safety hazard caused when the balancing weight falls in the state of a freely-falling body, to mechanical equipment and operating personnel.
Description
Technical field
The utility model relates to a kind of used for oil extractor safety device, is a kind of multifunctional emergency brake that is attached on the balance weight specifically.
Prior art
During the operation of steel cable oil pumper, the dynamic equilibrium of sucker rod elevator and balance weight is by the polished rod load of elevator end and balance weight, connects by steel cable and realizes.But when because long-term continual running, former thereby when disrumpent feelings because of wearing and tearing etc. when steel cable, balance weight can descend with free falling body state, brings safety hazard for plant equipment and operating personnel.
Summary of the invention
In view of this, the oil pumper multifunctional emergency brake that provides of the utility model solves the safety work problem.
The adjustable movable counterweight combination is made up of multiple-grooved movable pulley, pulley bracket, vibration damping or holddown spring, pulley base, mandrel, balance weight body, brake linkage, guide pad and push rod, gathering sill, the axis of guide, moving counterweight, dead counterweight, spring guide, mandrel nut etc. as figure.Accident brake be installed in pulley bracket and, between the balance weight body, and integrate with it.
When the adjustable movable counterweight combination was in place, Yin Qishang was not connected with steel cable with the elevator end, and vibration damping or holddown spring are in free state, so guide pad and push rod are in normal run location.The guide pad direction along ng a path is longer, both play the guiding role, and can prevent occurring when balance weight moves up and down stuck phenomenon; Its bigger contact surface also can play braking action preferably.When mentioning the adjustable movable balance weight, when the pulley base upwards compresses vibration damping or holddown spring, vibration damping or holddown spring are compressed, and the effect of vibration damping or holddown spring at this moment mainly is a vibration damping, eliminate the harmful effect that the adjustable movable balance weight produces when bracket upright post moves up and down.When the steel cable between adjustable movable balance weight and elevator is disrumpent feelings, vibration damping or holddown spring are because of no external force effect, the state of affranchising opens, and the propelling sheave base is downward, and the moving connecting rod of band brake moves outward, order about guide pad and push rod is overhanging, press to guide rail, and under the cooperation of the gravity of balance weight and brake linkage angle, press tight more more, finally braked, being provided with of push rod is the intangibility dead angle rapidly when angle can be fallen; The security protection effect is played in rapid unfreezing when last carrying.
Characteristics of the present utility model are:
1, form compact conformation with pulley base and balance weight body, radial dimension meets the demands, the adjustable movable counterweight combination that axial dimension is little;
2, it is multi-functional to have a brake hard of the vibration damping that moves up and down, guiding and disconnected rope;
3, make full use of simple and direct linkage and slide block mechanism and spring governor motion, realize brake hard and unfreezing fast.
Description of drawings
Fig. 1 is an adjustable movable balance weight structural representation.
Fig. 2 is the multifunctional emergency brake structural schematic diagram that is attached on the balance weight.
Among the figure: on behalf of multiple-grooved movable pulley, symbol 2, symbol 1 represent pulley bracket, symbol 3 to represent vibration damping or holddown spring, symbol 4 to represent pulley base joint, symbol 5 represents mandrel, symbol 6 to represent balance weight body, symbol 7 to represent brake linkage, symbol 8 to represent guide pad and push rod, symbol 9 to represent gathering sill, symbol 10 to represent the axis of guide, symbol 11 deputy activity counterweights, symbol 12 to represent dead counterweight, symbol 13 to represent spring guide, symbol 14 to represent the mandrel nut.
The specific embodiment
As shown in the figure, a kind of balance weight accident brake, comprise brake linkage, guide pad and push rod, gathering sill, the axis of guide, it is characterized in that accident brake is attached on the balance weight, under the brake linkage dress pulley base joint, brake linkage is connected in the gathering sill by the axis of guide, slidably, push rod is arranged in the gathering sill, and the push rod two ends have guide pad, protrude in balance weight body and are positioned on the balancing weight.
Claims (1)
