Abstract

Safety bumpers with a counter weight are formed by the counter weight 4, vertical shafts 5, safety bumpers I3 and safety bumpers II6, wherein two safety bumpers I3 and two safety bumpers II6 are mounted on a bottom board of the counter weight 4 so as to form general counter weight of a W-shaped traction pumping unit, two vertical shafts 5 are mounted on a diagonal line on the front side of the bottom board, and the safety bumpers I3 and the safety bumpers II6 are respectively sleeved on two vertical shafts 5. When the safety bumpers are used, the safety bumpers I3 and the safety bumpers II6 are perpendicular to the counter weight 4; when the counter weight 4 falls on the safety bumpers, the safety bumpers I3 and the safety bumpers II6 are located in the same plane and are mutually parallel; when the safety bumpers are stored, two safety bumpers are at diagonal positions and are in mutually three-dimensional intersection. Oblong through holes on the safety bumpers are matched with a gap between the vertical shafts 5 in width so as to bring convenience to positioning and rotation of the vertical shafts, and the length of the oblong through holes is 300-400 millimeters so as to bring convenience to front-and-back adjustment and enable the safety bumpers I3 and the safety bumpers II6 to be at a perpendicular position on a stull 2 of a rack. The counter weight of the safety bumpers can enable a car to be stopped on any stulls of the rack safely and reliably at will, and steel of the counter weight is saved, use is convenient, and the safety bumpers can not be stolen.

Description

With the counterweight safety bar

Technical field

The utility model relates to a kind of petroleum machinery, relate to especially that a kind of oil extraction in oil field uses without beam pumping unit.

Background technology

Development along with modern science and technology, huge variation has occured in the oil pumper technology that oil extraction in oil field is used, developed into without beam pumping unit by upper century-old consistent beam pumping unit of past, wherein, without the beam pumping unit chain drive pumping unit of having derived again, the crank connecting link oil pumper, linear oil pumping machine, belt oil pumping machine, W type towing oil-pumping machine etc., wherein, W type towing oil-pumping machine is high with its power saving rate, and noise is low, and transferring ginseng convenient is characteristics, development in recent years is very fast, be subject to the favor in oil field, but also there is certain drawback in safety device wherein-counterweight safety bar, when namely oil well needs operation, need counterweight to be placed on a certain stull safety bar of frame the load of then seting out.Stolen in order to prevent safety bar, the designer is fixed on safety bar and counts from top to bottom in the second gear stull, at ordinary times, two safety bars are hung vertically on the frame, when needing to use, the free end of safety bar is mentioned in the frame stull that is put into horizontal level, this kind mechanism has solved the problem that counterweight is placed safely at second gear preferably, but by after using, finds to still have deficiency, namely can not satisfy counterweight and be parked in arbitrarily on a certain shelves of the frame stull position, make troubles for construction, operation.

Summary of the invention

In order to overcome above-mentioned shortcoming, design a kind ofly with the counterweight safety bar, safety bar is placed on the bottom of counterweight, become one with counterweight, move with counterweight on the one hand, at will which crosspiece in frame all can stop, and safety is placed counterweight.Increase on the one hand again the weight of counterweight as the part of counterweight, save steel.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of with the counterweight safety bar, by counterweight 4, vertical shaft 5, safety bar I 3, safety bar II 6 consist of, safety bar I 3, safety bar II 6 are installed on counterweight 4 base plates, two vertical shafts 5 are installed on the counterweight 4 base plate front side diagonal, safety bar I 3, safety bar II 6 are enclosed within respectively on two vertical shafts 5, when using safety bar, safety bar I 3, safety bar II 6 are perpendicular with counterweight 4, during collection, safety bar I 3, safety bar II 6 rotations are superimposed upon counterweight 4 base plate diagonal positions.Oblong through hole on safety bar I 3, the safety bar II 6, width and vertical shaft 5 matched in clearance are convenient to location and rotation, and length is 300-400mm, regulates before and after being convenient to, and safety bar I 3, safety bar II 6 are in vertical position in frame stull 2.A framework casing of placing two safety bars is set below counterweight, by base plate, two end side panels, before and after can overturn 180 ° overhead door of side consist of, in box bottom front side diagonal positions two vertical shafts are set, on safety bar, respectively process an oblong through hole, hole and vertical shaft matched in clearance, the hole is about 300-400mm, two safety bars are respectively installed on two vertical shafts, wherein a safety bar lies on the base plate, this thick stick can be centered by vertical shaft on base plate left rotation and right rotation, the position that matches with the base plate diagonal can be rotated into, also the position perpendicular with base plate can be rotated to.The cushion block of another root safety bar one of increase and the high 1-2mm of another root safety bar below its oblong through hole, also isometric, the wide oblong through hole of processing and safety bar on it, and with electric welding with the safety bar weldering be.This thick stick also can left rotation and right rotation, both can be rotated into the base plate diagonal to match, and also can rotate the position vertical with base plate.It is three-dimensional crossing that the purpose that increases cushion block is that this root safety bar and another root safety bar form, they when rotated, mutually noninterfere.

In oil pumper when work,, counterweight and suspending point loading interlink with wire rope or belt or chain, and as trailer system, during upstroke, the work done of counterweight cooperation external rotor electric machine is moved polished rod, suspending point loading to top dead centre; During down stroke, polished rod, suspending point loading rely on deadweight and external rotor electric machine work done, with joint efforts counterweight are put into lower dead center, so go round and begin again, and iterative cycles just is drawn into ground to underground crude oil.In the oil pumper course of work, two safety bars are rotated to and counterweight base plate diagonal positions, close counterweight front and back side mounting door, see to be exactly integral body of counterweight from appearance, two safety bars are collected in the closed box of counterweight bottom, and own wt is again as the weight of counterweight.

When if oil pumper needs operation, need the load of seting out, at this moment; can shut down the correct position of counterweight in frame as required; the front and back side mounting door of counterweight bottom ° is thrown and is fixed on the counterweight wall from the upright position Rotate 180, rotate two safety bars and promote safety bar, make it vertical with counterweight; load is in frame front and back horizontal braces; start oil pumper operation button, make counterweight descending, counterweight is placed on two safety bars; then stop the load of to set out.

The beneficial effects of the utility model are: counterweight can be stopped with being intended to the arbitrary stull of frame, and is safe and reliable, and saves the counterweight steel, and safety bar can be not stolen yet.
