Abstract
An anti-falling device for the counterweight of an oil pumping unit comprises two fixed pulleys, a fixed pulley shaft, a wire rope, a cushioning device, a spring seat and the like; one of the fixed pulleys is sleeved on the fixed pulley in a movable manner, and the other is fixed on a motor seat on an upper platform; the front end of the wire rope passes through the pulley groove of the front fixed pulley and faces downwards to be connected with an upright post of the counterweight; the rear end of the wire rope passes through the pulley groove of the rear fixed pulley and is tightly pulled down; and then a spring and the spring seat are tied to the head of the wire rope. The spring and the spring seat serve as a small counterweight of the wire rope, meanwhile, when a polished rod on the front side breaks off, the spring serves as a cushion body and the spring seat serves as a headstock of the wire rope. The anti-falling device for the counterweight of the oil pumping unit can prevent the counterweight from falling on a concrete foundation and damaging the concrete foundation in the state of unbalance when the polished rod on the front side or a pumping rod breaks off.
Description
Technical field
The utility model relates to the novel no beam pumping unit of oil field petroleum machinery, particularly oil field.
Background technology
In recent years, the oil field is just at popular a kind of no beam pumping unit, and that this oil pumper has is energy-conservation, reduce discharging, efficient, environmental protection, saving steel, reduces distinguishing features such as manufacturing cost, but also there is certain flaw at secure context, for example, if the polished rod sucker rod takes place by disconnected taking off, the counterweight of oil pumper can be fallen to the concrete basis in moment, when serious, the concrete basis can be smashed, the counterweight self-deformation, even disintegrate.
Summary of the invention
In order to overcome the above-mentioned defective of above-mentioned oil pumper, the utility model provides a kind of oil pumper counterweight falling proof device, can effectively prevent counterweight when polished rod or rod broken, and counterweight is fallen suddenly under unbalance situation.
The technical solution of the utility model is such: oil pumper counterweight falling proof device is by two fixed pulleys, fixed pulley axis, wire rope, buffer, formations such as spring base, the fixed pulley pine is enclosed within on the fixed pulley axis, fixed pulley axis is fixed on the upper mounting plate motor cabinet, pass in the race of wire rope front end the past fixed pulley, downward then and counterweight column interrelates, the rear end of wire rope is passed through from rear side fixed pulley grooving, and tension downwards, on this steel wire rope head, fasten spring and spring base again, this spring and spring base are the little counterweight of wire rope, again can be in that the front side polished rod be disconnected when taking off, spring is as buffer body, spring base was in time held counterweight before being about to bump ground as the wire rope headstock.
The beneficial effects of the utility model are: take technique scheme can make the oil pumper counterweight when front side polished rod or rod parting, prevent that counterweight from dropping on the concrete basis under imbalance state, thereby cause the damage on concrete basis.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified

Fig. 2 is the utility model counterweight fall arrest structure principle chart
Among Fig. 1: 1, motor, 2, upper mounting plate, 3, the counterweight falling proof device, 4, wire rope, 5, front side polished rod load running block, 6, polished rod eye, 7, rear side counterweight running block, 8, counterweight, 9, frame, 10, well head, 11, overlapping tire, 12, support, 13, the concrete basis.
Among Fig. 2: 14, fixed pulley I, 15, fixed pulley axis I, 16, fixed pulley II, 17, fixed pulley axis II, 18, the restriction seat, 19, wire rope, 20, spring, 21, spring base.
The specific embodiment
In present embodiment Fig. 2, support upper mounting plate 2 is as the carrier of counterweight fall arrest, the position of intersecting at center line vertical line and upper mounting plate with counterweight 8 is provided with movable pulley I, movable pulley I pine is enclosed within on the movable pulley axle, movable pulley axle II is installed in position after upper mounting plate leans on, and movable pulley II pine is enclosed within on the movable pulley axle II, at downward tangent line in movable pulley right side and platform lower limb intersection restriction seat 5 is set again, again wire rope 19 is placed into movable pulley I, in the grooving of II, front end and counterweight 8 with wire rope is connected again, the rear end is connected with spring base 21 with spring 20, adjusts length of steel wire rope.When oil pumper moves, traction sheave drive front side polished rod suspending point loading and rear side counterweight by the motor both sides are moved up and down, simultaneously, the wire rope of counterweight falling proof device is operation up and down synchronously under the traction of counterweight 8, when if disconnected taking off takes place in front side polished rod or sucker rod, the counterweight of rear side can be fallen very soon, when counterweight is fallen, counterweight drives the wire rope operation downwards in the lump of falling proof device, when the rear end of falling proof device wire rope ran to top dead centre, spring 20 just contacted with restriction seat 18, because of the cushioning effect of spring 20, just haul counterweight 8 deceleration jogging, simultaneously, counterweight 8 bottoms contact with overlapping rubber tyre 11, under dual elastic buffer effect up and down, cushion final counterweight 8 safe soft landings repeatedly by several times.Thus and thus, counterweight neither can smash the concrete basis, can not make the impaired distortion of counterweight self again.
Claims (1)
1. oil pumper counterweight falling proof device, constitute by two fixed pulleys, fixed pulley axis, wire rope, buffer, spring base etc., it is characterized in that: the fixed pulley pine is enclosed within on the fixed pulley axis, fixed pulley axis is fixed on the upper mounting plate motor cabinet, pass in the race of wire rope front end the past fixed pulley, downward then and counterweight column interrelates, and the rear end of wire rope is passed through from the fixed pulley grooving of back, and tension downwards, on this steel wire rope head, fasten spring and spring base again.
