Abstract
A ground control type safety bar device comprises safety bars, fixed pulleys, rope winders, steel wire ropes, control hand wheels and the like. Steel wire rope fasteners are welded to two lateral sides at two ends of a safety machine. Eight fixed pulleys are welded to a frame. The middle portions of the steel wire ropes are fixed on the rope winders through eight guide wheels. Two ends of the steel wire ropes respectively winds the fixedly pulleys and the guide wheels and to be connected with the rope fasteners on two sides of the safety bars, the length of the steel wire ropes is adjusted, and the safety bars can move forwards and backwards during use by manually rotating the control hand wheels. When a counter weight needs to be mounted, the hand wheels are manually rotated anticlockwise, and the rope winders allow the safety bars to move towards the center. When the safety bars need to be removed, the hand wheels are manually rotated clockwise to allow the safety bars to retract towards two sides, and an up-down moving passage is formed for the counter weight. The ground control type safety bar device has the advantages that the hand wheels are rotated on the ground during control, the rope winders are rotated anticlockwise or clockwise, the steel wire ropes control the safety bars to move towards the center or move towards two sides, and the device is safe and convenient to operate and reliable in performance.
Description
Technical field
The present invention relates to a kind of petroleum machinery, especially relate to that a kind of oil extraction in oil field uses without beam pumping unit.
Background technology
The generation of beam pumping unit and the application history of existing more than 100 year so far, along with the development of new and high technology and the needs of oil production technology, the existing energy consumption of beam pumping unit is high, counterbalance effect is poor, adjust ginseng difficulty, point suspension movement acceleration change is large, to sucker rod, the defects such as the impact of oil well pump running quality is large progressively show especially out, so novel structure, operation balance, long stroke, low jig frequency, volume is little, lightweight, consume energy low, the W type towing oil-pumping machine that noise is low comes out, and put into production and apply, meet to a certain extent the demand in market, in performance, improve running quality, reduce energy consumption, improve system effectiveness, but, there is certain potential safety hazard in the counterweight safety bar of this type oil pumper, while being oil field operation, need operating personnel to climb in frame, safety bar is placed in frame stull, again counterweight is placed on safety bar, whole operating process, must carry out in strict accordance with operation sequence, otherwise will be dangerous.
Summary of the invention
In order to overcome above-mentioned shortcoming, reduce work high above the ground, eliminate safe hidden trouble, ensure operator safety, design a kind of ground control formula safety bar, directly, at ground control safety bar, eliminate safe hidden trouble, reach safe, reliable, easy to operate.
The technical solution adopted for the present invention to solve the technical problems: ground control formula safety bar device is by safety bar, fixed pulley, ropewinder, wire rope, the formations such as hand wheel.In Liang Ge side, the two ends of safety bar, the wire line hitch of burn-oning, 4 fixed pulleys of burn-oning in frame, wire rope middle part is screwed on ropewinder, and two of wire rope is walked around from fixed pulley respectively, is finally connected with safety bar both sides sling again, and adjust length, handwheel is by axle control ropewinder, and wire rope is connected with ropewinder, and wire rope links together by guide wheel, pulley and safety bar.When operation, at ground rotation handwheel, contrary (suitable) hour hands rotate ropewinder, and wire rope control safety bar is drawn close to center or to two side shiftings.When use, place when counterweight if need, rotate counterclockwise handwheel, ropewinder drives safety bar to draw close to center, counterweight is placed on safety bar; If need remove safety bar, first counterweight is promoted to a segment distance, clockwise rotate handwheel, safety bar is drawn in to both sides, abdicate and move up and down passage for counterweight.
The invention has the beneficial effects as follows, can handle on ground that high-altitude counterweight safety bar is drawn close to center or to two side shiftings, easy to operate, safe and reliable.
Brief description of the drawings
Fig. 1 is the present invention's arrangement diagram in frame.
Fig. 2 is sectional drawing graphics of the present invention.
In the drawings 1, fixed pulley, 2, safety bar, 3, wire rope, 4, guide wheel, 5, bearing, 6, bearing gland, 7, ropewinder, 8, axle, 9, operation handwheel.
specific implementation method:
Utilize the method for machining, make fixed pulley 1, guide wheel 4, ropewinder 7, handwheel 9, bearing 5, bearing gland 6, ropewinder 7, rotating shafts 8 etc., buy square steel pipe safety bar 2 by buying, wire rope 3 etc.; Utilize the method for electric welding by each pulley base, wheel stand, bearing 5, is welded in frame, finally according to figure by each steel wire penetrating fixed pulley 1, guide wheel 4, ropewinder 7, last two ends fag end is connected with safety bar sling, formation ground control formula safety bar device.While using safety bar, the safety bar on both sides need be drawn close to centre, be rotated counterclockwise respectively two groups of hand wheels 9, drive ropewinder 7 to rotate counterclockwise roll wire rope 3 by axle 8, wire rope 3 pulls safety bar 2 to move to centre by guide wheel 4 and fixed pulley 1.
While not using safety bar, first counterweight is promoted to a segment distance to top dead centre, clockwise rotate respectively again two groups of hand wheels 9, drive ropewinder 7 to clockwise rotate by wire rope 3 by axle 8 and pull safety bar 2, to frame two side shiftings, two safety bars all move to frame both sides, move up and down and abdicate space for counterweight.
