Abstract
A kind of pulley-type horse head pin extractor, including：First pulley（1）, the second fixed pulley（2）, cord（3）, ratchet mechanism（4）.It is characterized in that：The steel wire rope（3）Head end is fixed on the first fixed pulley（1）Support on, bypass and be fixed on horse head pin（7）Second fixed pulley of head end（2）With the first fixed pulley for being fixed on walking beam end bottom（1）, end is fixed on Framework of Pumping Unit（8）The ratchet mechanism of bottom（4）Ratchet shaft on.The utility model operating personnel are changed into ground quiet run from work high above the ground, eliminate potential safety hazard, it is ensured that the personal safety of operating personnel.Ratchet mechanism has auto-lock function, can effectively prevent the resilience of horse head pin.There is assembly pulley labour-saving to act on, the frictional resistance that can easily overcome the elastic force of back-moving spring and be produced because horse head pin such as gets rusty at the reason, alleviate the labour intensity of operating personnel, and it is time saving and energy saving to operate, rate when improving well recovery.
Description
Technical field
Horse head pin extracts utensil when the utility model is related to beam pumping unit operation, specifically a kind of pulley-type donkey
Head pin extractor.
Background technology
Need to overturn horse head during beam pumping unit workover treatment, upper and lower round working space is conceded to suspension hook, be easy to repair
Well operations.Lateral rotating type horse head needs to extract horse head pin when overturning, and releases horse head pin to the position-limiting action of horse head, makes horse head side
Turn 175 °.During workover treatment, operating personnel need to wear safety belt, climb to middle (center) bearing position, tense mule head pin rocking arm, make spring
Shrink, horse head pin exits cotter way, release position-limiting action of the pin to horse head.Original pendulum horse head operating process is as follows：Firstly, it is necessary to
Operating personnel carry out work high above the ground, in four meters of left and right middle (center) bearing position operations of height；Secondly, it is necessary to overcome back-moving spring
Elastic force, increases dangerous to work high above the ground human users, there is potential safety hazard.
The content of the invention
The purpose of this utility model is to provide a kind of pulley-type horse head pin extractor, overcomes what above-mentioned prior art was present
Defect.
The technical solution of the utility model is achieved in the following ways：
The utility model includes：First fixed pulley, the second fixed pulley, steel wire rope, ratchet mechanism.The steel wire rope head end is consolidated
It is scheduled on the support of the first fixed pulley, bypasses and be fixed on the second fixed pulley of horse head pin head end and be fixed on walking beam end bottom
The first fixed pulley, end is fixed on the ratchet shaft of the ratchet mechanism of Framework of Pumping Unit bottom.
The support of the first fixed pulley is " U " type structure in above-mentioned pulley-type horse head pin extractor, and upper end is vertically welded in
Walking beam end lower middle part, bottom is provided with pulley spindle, and pulley spindle is provided with the first fixed pulley.
The ratchet shaft ending vertical of ratchet mechanism is fixed on an oil pumper bottom left side in above-mentioned pulley-type horse head pin extractor
On the crossbeam of side.
Compared with the prior art the present invention has advantages below：
（1）Operating personnel are changed into ground quiet run from work high above the ground, eliminate potential safety hazard, it is ensured that operating personnel's
Personal safety；
（2）Ratchet mechanism has auto-lock function, can effectively prevent the resilience of horse head pin；
（3）There is assembly pulley labour-saving to act on, and can easily overcome the elastic force of back-moving spring and because horse head pin is given birth to
The reasons such as rust and the frictional resistance that produces, alleviate the labour intensity of operating personnel；
（4）Operating process is time saving and energy saving, rate when improving well recovery.
Brief description of the drawings
Fig. 1-utility model main structure diagram
1. first fixed pulley in figure, 2. the second fixed pulley, 3. steel wire rope, 4. ratchet mechanism, 5. walking beam, 6. horse head, 7.
Horse head pin, 8. Framework of Pumping Unit.
Specific embodiment
It is further open technical scheme, is elaborated by embodiment with reference to Figure of description：
Pulley-type horse head pin extractor is made up of the first fixed pulley 1, the second fixed pulley 2, steel wire rope 3, ratchet mechanism 4.
The head end of the steel wire rope 3 is fixed on the support of the first fixed pulley 1, bypasses the second fixed pulley 2 for being fixed on the head end of horse head pin 5
With the first fixed pulley 1 for being fixed on walking beam end bottom, end is fixed on the ratchet of the ratchet mechanism 4 of the bottom of Framework of Pumping Unit 8
On axle.
When horse head pin is pulled out, the ratchet shaft of the ratchet mechanism 4 that turns right drives steel wire rope 3 to be wound on ratchet shaft, steel wire
Rope 3 is pulled outwardly horse head pin 7 by the first fixed pulley 1 and the straight line of the second fixed pulley 2, and ratchet mechanism 4 has stopping function, overcomes
The reaction force of the spring of horse head pin 7, prevents reversion, continues rotating ratchet axle, untill extraction horse head pin 7.Extract donkey
After head pin 7, horse head is rotated 175°Just do not influence oil well operation.Operating personnel are changed into ground and steadily grasp from work high above the ground
Make, eliminate potential safety hazard, it is ensured that the personal safety of operating personnel.
