Abstract

A kind of Telescopic safe thick stick device, it is by safety bar, sleeve, screw-type jack, the formations such as crank.At counterweight substrate, to burn-on four sleeves, then four safety bars are placed in sleeve, screw-type jack is connected with four safety bars, and adjust collapsing length, crank is enclosed within the screw mandrel of jack, and safety bar can stretch, when laying counterweight left and right, crank rotates clockwise jack screw mandrel, jack is stretched out to both sides, and promote safety bar and stretch out to the left and right, counterweight is just seated on four safety bars and carries on a shoulder pole on the cross-arm of frame.Regain safety bar, then rotate counterclockwise jack screw mandrel with crank, jack is connected with safety bar and drives safety bar to central reduction, abdicates run passage up and down for counterweight.This Telescopic safe thick stick device is convenient to operation, safe and reliable.

Description

A kind of Telescopic safe thick stick device
Technical field
The utility model relates to a kind of oil field equipment, especially relate to a kind of oil field without beam pumping unit.
Background technique
The invention 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, energy consumption existing for 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 ride quality is large progressively highlight, so novel structure, run balance, long stroke, low jig frequency, volume is little, lightweight, consume energy low, the non-beam beam-pumping unit that noise is low comes out, and put into production and apply, meet the demand in market to a certain extent, performance improves ride quality, reduce energy consumption, improve system effectiveness, but, but there is certain potential safety hazard in the counterweight safety bar of this type pumping unit, namely during oil field operation, operator are needed to climb in frame, safety bar is placed in frame stull, again counterweight is placed on safety bar, whole operating process, it is all manual operations, personnel operate abnormally dangerous below the counterweight of nearly ten tons of weights of being everlasting, once polished rod, rod parting, consequence is by hardly imaginable.
Summary of the invention
In order to overcome above-mentioned shortcoming, reducing high-risk operations, eliminating safe hidden trouble, ensure operator safety, design a kind of Telescopic safe thick stick device, it is by safety bar, sleeve, top board, screw-type jack, the formations such as crank.At counterweight substrate, then four safety bars are placed in sleeve by four sleeves of burn-oning, and they are Spielpassung.By screw-type jack and four safety bar electricity consumptions are soldered connects, and adjust collapsing length, crank is enclosed within the screw mandrel of jack, transhipment crank safety bar can left and right flexible.When laying counterweight, crank rotates clockwise jack screw mandrel, and jack is stretched out to both sides, joins safety bar and stretches out to the left and right.Four safety bars are all carried on a shoulder pole in frame stull, and counterweight is just steadily seated on safety bar.Regain safety bar, then rotate counterclockwise jack screw mandrel with crank, safety bar, to central reduction, is abdicated for counterweight and is run passage up and down.Easy to operate, reliably.
The beneficial effects of the utility model are, the cat ladder of pumping unit can be handled counterweight safety bar and draw close to center or stretch out to the left and right, convenient to operation, safe and reliable.
Accompanying drawing explanation
Fig. 1 is the plan view of the utility model in frame
Fig. 2 is the plan view of the utility model in frame
Fig. 3 is the left view of the utility model in frame
In the drawings: 1, safety bar, 2, sleeve, 3, top board, 4, screw-type jack, 5, crank, 6, counterweight, 7. pumping unit shelf.
specific implementation method:
Be embodiment with Fig. 1: the method utilizing machining, make screw-type jack 4, crank 5, safety bar 1, sleeve 2, top board 3 etc.; Utilize the method for electric welding to be welded on top board 3 by both sides safety bar, top board 3 is welded on screw-type jack 4, form Telescopic safe thick stick device.During use safety thick stick, need the safety bar of both sides to stretch out to the left and right, rotate clockwise screw-type jack 4 with crank 5, stretched out to the left and right by the very heavy flexible pushes safety bar 1 of screw-type.
Not during use safety thick stick, first counterweight is promoted a segment distance to top dead center, safety bar is made to leave frame stull, screw-type jack 4 is rotated counterclockwise again with crank 5, pull safety bar 1 to central reduction by the very heavy flexible position of screw-type, four safety bars are all retracted to counterweight inside, run up and down abdicate space for counterweight.
