Abstract
The utility model disclose a improved dual brake apparatus for oil extractors, comprising an oil extractor handbrake and a brake ring which is sleeved on an oil extractor power shaft, an adjusting thread rod which is sleeved on a pressure spring. The thread rod is arranged between the brake ring's two opening legs. One end of an outward extend pull-rod is fixed on one open leg of the brake ring, and the other end is free and connected with the extractor handbrake through a steel wire rope. The other leg of the brake ring is equipped with a hydraulic cylinder. The free end of the piston rod is connected with a pull rod which is equipped with a leg of the brake ring. The hydraulic cylinder is connected with a pressure pump which is equipped with the oil extractor's stander through the hydraulic oil pipeline. This present utility model not only can ensure the oil extractor a reliable brake but also have the advantages of simple structure, convenient operation and effectively eliminating the losses in property and human lives of the operators, making sure enterprises' normal production.
Description
Technical field
The utility model belongs to the braking device of oil-field oil pumper, the two brake devices of particularly improved pumping unit.
Background technique
The oil-field oil pumper braking device is pumping unit is guaranteed operating personnel's personal safety when operations such as maintenance, maintenance an important braking device.Existing pumping unit braking device is brake ring at pumping unit power axle head suit, open between the pin for two of brake ring the adjusting screw rod that is set with pressure spring on it is being set, one of brake ring open affixed outwardly directed pull bar on the pin, the free end of pull bar links to each other with the pumping unit rim brake by wire rope.Pulling pumping unit rim brake is held the relative compression of two pin of brake ring tightly the pumping unit line shaft thereby just can spur pull bar by steel cable, realizes the braking of pumping unit.But in production practices, there is the firm inadequately problem of brake in this pumping unit braking device, and brake failure sometimes the operating personnel is usually taken place squeezed the accident of hindering, injuring by a crashing object by the pumping unit running gear.
Summary of the invention
The purpose of this utility model is to provide a kind of improved pumping unit two brake devices, can not only make pumping unit realize reliable skidding, and simple in structure, swift to operate, can stop operator's human casualty accident effectively, guarantee enterprise's ordinary production.
The purpose of this utility model is achieved in that the two brake devices of a kind of improved pumping unit, comprise the pumping unit rim brake and be sleeved on brake ring on the pumping unit line shaft, open between the pin for two of brake ring the adjusting screw rod that is set with pressure spring on it is being set, open affixed outwardly directed pull bar on the pin at one of brake ring, the pull bar free end links to each other with the pumping unit rim brake by wire rope, open at the another of brake ring oil hydraulic cylinder is installed on the pin, the piston rod free end of oil hydraulic cylinder is opened pin with the brake ring that pull bar is installed and is linked to each other, and oil hydraulic cylinder links to each other with pressure pump on being installed in pumping unit shelf by hydraulic oil pipe.
During the utility model work, if pumping unit is carried out brake operating, spur rim brake earlier, spur pull bar downwards by wire rope, the pumping unit line shaft is held inside receipts of two pin of brake ring tightly brake by pull bar, start oil hydraulic pump then, the oil hydraulic cylinder action that links to each other with oil hydraulic pump, the piston rod of oil hydraulic cylinder is also inwardly received two pin of brake ring and further the pumping unit line shaft is held tightly, thereby realizes two braking brakes.Compare with traditional pumping unit braking device, the utility model can not only make pumping unit realize reliable skidding, and it is simple in structure, swift to operate, no longer need operator to climb to pumping unit line shaft place and carry out manual adjustment, stop operator's human casualty accident effectively, guaranteed enterprise's ordinary production.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing is a main TV structure schematic representation of the present utility model.
In the accompanying drawing: 1-rim brake seat; 2-pumping unit rim brake; The 3-pressure pump; The 4-hydraulic oil pipe; The 5-pull bar; The 6-pressure spring; The 7-oil hydraulic cylinder; The 8-piston rod; The 9-commutator.
Embodiment
The two brake devices of a kind of improved pumping unit as shown in drawings, comprise pumping unit rim brake 2 and are sleeved on brake ring on the pumping unit line shaft that pumping unit rim brake 2 is installed on the rim brake seat 1.Between two pin of brake ring the adjusting screw rod that is set with pressure spring 6 on it is being set, can realizing preliminary braking by adjusting screw rod.Open affixed outwardly directed pull bar 5 on the pin at one of brake ring, pull bar 5 free ends link to each other with pumping unit rim brake 2 by the wire rope that is installed on the commutator 9, open at the another of brake ring oil hydraulic cylinder 7 is installed on the pin, oil hydraulic cylinder 7 is plunger piston fluid pressure cylinder or other forms of oil hydraulic cylinder.Piston rod 8 free ends of oil hydraulic cylinder 7 are opened pin with the brake ring that pull bar 5 is installed and are linked to each other, and oil hydraulic cylinder 7 links to each other with pressure pump 3 on being installed in pumping unit shelf by hydraulic oil pipe 4.Start pressure pump 3, can drive piston rod 8 actions of oil hydraulic cylinders 7, two of brake ring are opened pin tighten up relatively, realize secondary braking by hydraulic oil pipe 4.Pressure pump 3 is manual jack or electric hydraulic pump or pneumatic pump.
