Abstract
The utility model relates to a tool specially used for dismantling and assembling an oil extractor crank pin, which is applied to the dismantling and assembly of a beam-pumping unit crank pin in an oil field. The tool mainly comprises a connecting nut, a guiding slide bar, an impact block and a baffle, wherein two ends of the connecting nut are provided with internal threads, the internal thread at the other end of the connecting nut is connected with the guiding slide bar, and the guiding slide bar is cylindrical. The guiding sliding bar is sheathed with the cylindrical impact block, and the impact block is provided with an axial through hole. The other end of the guiding slide bar is fixed with the baffle. The tool has the effects of being capable of installing or dismantling the oil extractor crank pin, improving the installation quality, reducing the maintenance times of the crank pin, and improving the operation time rate of the oil extractor, thus overcoming the defect of using a boss hammer for tamping in the prior art, having convenient use and safety and reliability, eliminating the occurrence of the accident of falling from high altitude, and accelerating the stroke of the oil extractor by two to three times.
Description
Technical field
The utility model relates to oil field oil recovery machiner technical field, and particularly beam pumping unit is a kind of oil pumping machine crank pin disassembly and assembly specific purpose tool.
Background technology
What use was recovered the oil in the oil field is beam pumping unit, and the heavy connection of beam pumping unit connecting rod and crank is a crank pins.Crank pins one end is the tapering pin, in tapering pin end external screw thread is arranged.When the maintenance oil pumper, often need dismounting oil pumping machine crank pin.
When transferring stroke dismounting crank pins, at first lay down locking plate and unload loose nut again, the people stands in above the reduction box, pounds the crank pins locking nut with sledgehammer bearing pin is got.Owing to be work high above the ground operator neither one foothold stably again, be difficult for standing firm, firmly be restricted, strength all (fully) is brought into play, needs to rotate with the several people to use slowly getting that sledgehammer one hammers into shape, waste time and energy, labour intensity is big, and inefficiency has certain danger, in case sledgehammer fans the air, the operator just has the danger of falling from reduction box.
When cranking pin, nut is screwed into crank pins, tightening the back is with the lashing force of screw thread, crank pins, guide and crank hole to be combined closely with the big protuberance of beating nut.Fan the air sometimes or get on the crank with sledgehammer, operate very inconveniently, waste time and energy, increased the difficulty of work.
The utility model content
The purpose of this utility model is: a kind of oil pumping machine crank pin disassembly and assembly specific purpose tool is provided, utilizes the inertial impact force of impact block, energy is for convenience detach, installation oil pumping machine crank pin, increases work efficiency.
The technical solution adopted in the utility model is: oil pumping machine crank pin disassembly and assembly specific purpose tool, mainly form by attaching nut, guiding slide bar, impact block and baffle plate, it is characterized in that: there is internal thread at attaching nut's two ends, and the internal thread of attaching nut's one end is to connect oil pumping machine crank pin end external screw thread to use.Attaching nut's other end internal thread is connected with a guiding slide bar, and the guiding slide bar is the cylinder bodily form.Be with columned impact block on the guiding slide bar, impact block has axially extending bore.The other end of guiding slide bar is fixed with baffle plate.After attaching nut and oil pumping machine crank pin end external screw thread were tightened, the impact block that reciprocatingly slides can utilize the inertial impact force of impact block, beats attaching nut or baffle plate, and the vibration power of sending can dismounting oil pumping machine crank pin.
To use spanner in order going on the market the attaching nut, to screw the attaching nut, is regular hexagon at the outer wall of attaching nut's one end.
Described baffle plate can adopt screw thread to be fixed on the end of guiding slide bar; Also can adopt welding method, baffle plate is fixed on the end of guiding slide bar.
The using method of oil pumping machine crank pin disassembly and assembly specific purpose tool: consult Fig. 1.
When (1) dismantling crank pins: the clamp nut of crank pins is unloaded down.Attaching nut 1 is screwed on the crank pins screw thread, and attaching nut 1 connects guiding slide bar 2, puts impact block 3 on guiding slide bar 2, fixes baffle plate 4 in guiding slide bar 2 ends.Shift impact block 3 onto back, firmly push impact block 3 to attaching nut 1 suddenly, impact block 3 produces motive force, make crank pins break away from crank hole, if crank pins is tighter, when a people power is not enough to crank pins released, can two the people is afterburning simultaneously that crank pins is got.
When (2) cranking pin: attaching nut 1 is screwed on the crank pins screw thread, and guiding slide bar 2 connects with attaching nut 1, baffle plate 4 is fixed on the end of guiding slide bar 2 again.Impact block 3 is shifted the front onto, firmly pushes impact block 3 to baffle plate 4 suddenly, produces anti-motive force crank-pin and guide, crank hole are combined closely.
The beneficial effects of the utility model: the utility model oil pumping machine crank pin disassembly and assembly specific purpose tool, energy installation or removal oil pumping machine crank pin has improved installation quality, the maintenance frequency of minimizing crank pins, the rate during running that improves oil pumper.Overcome the deficiency that the past pounds with sledgehammer, easy to use, safe and reliable, eliminated the generation of high-altitude falling accident.Improve oil pumper and transferred the speed 2～3 times of stroke.
Description of drawings
Fig. 1 is the utility model oil pumping machine crank pin disassembly and assembly specific purpose tool structural profile schematic diagram.
Among the figure, 1. attaching nut, 2. guiding slide bar, 3. impact block, 4. baffle plate.
The specific embodiment
Embodiment 1: with an oil pumping machine crank pin disassembly and assembly specific purpose tool is example, and the utility model is described in further detail.
Consult Fig. 1.The utility model oil pumping machine crank pin disassembly and assembly specific purpose tool mainly is made up of attaching nut 1, guiding slide bar 2, impact block 3 and baffle plate 4.
An end of attaching nut 1 has the internal thread of connecting crank pin, and attaching nut 1 the other end has the M20 internal thread that connects guiding slide bar 2.It is 20 millimeters that attaching nut 1 is connected with an external diameter, the guiding slide bar 2 that internal diameter is 12 millimeters, 800 millimeters of the length of guiding slide bar 2.Be with a columned impact block 3 on the guiding slide bar 2, impact block 3 is the cylinder bodily form, 100 millimeters of external diameters, 100 millimeters of length.It is 21 millimeters axially extending bore that impact block 3 has diameter.The other end screw thread of guiding slide bar 2 is fixed with baffle plate 4.
The outer wall of attaching nut's 1 one ends is a regular hexagon.
