A cross bar is welded between the two upright posts, and the cross bar and the upright posts are welded into a ladder; two arc-shaped hooks are welded on the cross bar at the upper end; the upright posts are welded with handrails, and the handrails are arranged on one side surface of the ladder; the lower end of the ladder is welded with a pedal vertical to the upright post, and the pedal and the handrail are arranged on the same side face of the ladder; a polish rod support is welded on the cross rod in the middle part and is vertical to the cross rod, and the polish rod support is arranged on the other side surface of the ladder. The effect is as follows: the stable maintenance operation pedal is provided, the risk caused by high-altitude operation is avoided, and the use is safe and reliable.
Description
Technical field
The utility model relates to oil field oil-extracting well flight-line maintenance technical field, and particularly mouth of pumped oil well polished rod clamp maintenance is a well head operation staircase special-purpose in a kind of field maintenance operation.
Background technology
At present, at oil field sucker rod pumping well field operation, often need to adjust the oil pumper dead space, change load transducer.In operation, at first extract the clamp on the polished rod, carry out the oil pumper unloading again.Extracing the polish rod clamp period of the day from 11 p.m. to 1 a.m, need carry out ascend operation.Because the polished rod eye of oil pumper is bigger apart from the well head distance, operating personnel need step down on rubber gate or the packing box can go up operation, wherein has shortcoming: operating personnel step down in and have potential safety hazard on the packing box; Be easy to operating personnel's clothing is polluted; The unstable influence in underfooting is had an effect during operation, is difficult for the upper clip removal.At in this case, majority is to adopt at present
Case or other can bed hedgehopping object provide operation to ascend a height, do not have the platform of safety and stability during operation, personnel are not steady on one's legs in the above, need other staff to help to hold up steady.
The utility model content
The purpose of this utility model is: a kind of portable polished rod clamp dismounting staircase is provided, be easy to carry, form at 3 by hook and polished rod eyelid retractor and form the plane, its operating pedal provides firm, a stable pedal to operating personnel, wide adaptability, cleanliness of operation, convenience, safety.
The technical solution adopted in the utility model is: portable polished rod clamp dismounting staircase, mainly form by hook, cross bar, column, handrail, pedal and polished rod eyelid retractor, two root posts are parallel to each other, and are welded with cross bar between two root posts, and cross bar and column are welded into ladder; It is characterized in that: the quantity of cross bar is 4～10, is welded with two circular arc hooks on the cross bar of ladder upper end; Be welded with handrail on column, handrail is in a side of ladder; Vertical pillars is welded with pedal in the lower end of ladder, and pedal and handrail are in the same side of ladder; Also vertical cross bar is welded with the polished rod eyelid retractor on the cross bar at middle part, and the polished rod eyelid retractor can be supported on the oil pumping polish rod in the another side of ladder, is convenient to fix.
It is that the round steel of 10mm curves circular arc that hook adopts diameter, and between the distance 200～500mm between two hooks, the distance between two hooks will adapt to the width of oil pumper polished rod eye.
It is the 15mm coating steel pipe that column and cross bar adopt diameter; Pedal is a rectangular flat plate, and personnel stand on the pedal and operate, height proper operation safety.
The polished rod eyelid retractor is made up of pole and curved plate, is welded with the curved plate of a semicircle in the end of pole, and curved plate can be supported on the oil pumping polish rod.Be fixed with liner rubber in the inboard of curved plate, be used for increasing frictional force.
The beneficial effects of the utility model: the portable polished rod clamp dismounting of the utility model staircase, stable maintenance operation pedal is provided, evaded the risk that work high above the ground causes, safe and reliable.The staircase height is 130 centimetres, and portable polished rod clamp dismounting staircase pedal adopts diameter 15mm coating steel pipe to reach
Plate is made, and cost is low, is easy to carry, high safety, and is easy to use.Form a plane by two hooks and polished rod support ring, by geometrical principle as can be known 3 form a plane, stability is strong.Polished rod support ring inside is lined with rubber, and pedal adopts
Plate promptly helps anti-skidding.
