Abstract
The unloading buffer of the pumping unit is applied to the unloading buffer of the pumping unit in the oil field when the stroke is adjusted. Including base, a fixed section of thick bamboo, spring and backup pad, characterized by: at least two fixed cylinders are symmetrically welded on the base. The fixed cylinders are respectively provided with a spring. The upper end of the spring is fixed on the supporting plate. The base and the supporting plate are respectively provided with a notch, and the position of the notch is between the fixed cylinders. The width of the gap is between 28 and 32 millimeters. The effect is as follows: after the square clamp of the oil pumping unit is detached, the square clamp can be clamped by the notch, when the square clamp falls down, the spring between the base and the supporting plate plays a role in buffering, the oil pumping rod cannot be pulled, and potential safety hazards which may be caused when the oil pumping unit is detached are eliminated.
Description
Technical field
The utility model includes bar pumping unit technical field, supports a kind of special tool of sucker rod when particularly pumping unit unloads, and is a kind of pumping unit unloading buffer that has the support sucker rod of buffer function specifically.It is a kind of unloading buffer when being applied to pumping unit and adjusting stroke.
Background technique
At present, what the most oil recovery wells in oil field used is the sucker rod pumping machine, as beam pumping unit.Sucker rod pumping machine oil producing operation, needs are adjusted the stroke of sucker rod.When adjusting the rod stroke operation, at first to lay down the square clamp that pumping unit connects, both laid down the load that pumping unit bears.Behind the square clamp of laying down pumping unit, the square clamp meeting pelter under the sucker rod action of gravity that is fixed on the sucker rod is smashed packing box, and is caused sucker rod to pull on packing box.
The model utility content
The purpose of this utility model is: a kind of pumping unit unloading buffer is provided, overcome the square clamp of laying down pumping unit after, packing box is smashed in the pelter under the sucker rod action of gravity of square clamp, the deficiency that causes sucker rod to pull.
The technical solution adopted in the utility model is: the pumping unit unloading buffer comprises base, stationary magazine creel, spring and dunnage, it is characterized in that: be symmetrically welded with two stationary magazine creels on base at least.Spring is arranged respectively in the stationary magazine creel.The upper end of spring is fixed on the dunnage.A gap is respectively arranged on base and dunnage, and the position of gap is between stationary magazine creel.The width of gap is between the 28-32 millimeter.
Described spring is a spiral compression spring, and the quantity of the spiral compression spring in each stationary magazine creel can be 1, also can be 2.When the quantity of the spiral compression spring in each stationary magazine creel was 2,2 spiral compression springs were nested together.
For effective fixing spring, in stationary magazine creel, be welded with fixing column down, be welded with fixing column on the dunnage, the position of following fixing column and last fixing column is in spring.
Described gap bottom is semicircle.
The beneficial effects of the utility model: the utility model pumping unit unloading buffer has gap, behind the square clamp of laying down pumping unit on base plate and dunnage, Fang Kazi can be blocked by gap, when Fang Kazi fell, the spring between base and the dunnage played buffer function, can not pull sucker rod; Be that square clamp can not smash on the packing box because the support of pumping unit unloading buffer has been arranged in addition.The potential safety hazard that the pumping unit unloading buffer may cause in the time of eliminating the pumping unit unloading.
Description of drawings
Fig. 1 is the utility model pumping unit unloading buffer structural profile schematic representation.
Fig. 2 is the cross-sectional schematic representation of Fig. 1.
Among the figure, 1. base 2. descends fixing column, 3. stationary magazine creel, and 4. spring is 5. gone up fixing column, 6. dunnage, 7. gap.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Embodiment 1: consult Fig. 1.The utility model pumping unit unloading buffer, base (1) are 480 millimeters of block lengths, and be wide 200 millimeters, the steel plate that thickness is 25 millimeters.75 millimeters of stationary magazine creel (3) internal diameters, 350 millimeters of height.70 millimeters of spring (4) external diameters, free height is 500 millimeters.Dunnage (6) is 400 millimeters of block lengths, and is wide 200 millimeters, the steel plate that thickness is 20 millimeters.On base (1), be symmetrically welded with two stationary magazine creels (3).A spiral compression spring (4) is arranged respectively in two stationary magazine creels (3).The upper end of spiral compression spring (4) is fixed on the dunnage (6).On base (1) and dunnage (6) gap (7) is arranged respectively, the position of gap (7) is between stationary magazine creel (3).Consult Fig. 2.30 millimeters of the width of gap (7), bottom are semicircle.Be welded with fixing column (2) down in stationary magazine creel (3), be welded with fixing column (5) on dunnage (6), the position of following fixing column (3) and last fixing column (5) is in spring (4).45 millimeters of following fixing column (3) diameters, 70 millimeters of height; 45 millimeters of last fixing column (5) diameters, height 170 millimeters fixing columns (5)
Embodiment 2: embodiment 2 is substantially the same manner as Example 1, and difference is: the quantity of the spiral compression spring (4) in each stationary magazine creel (3) is 2, and 2 spiral compression springs (4) are nested together.Inside and outside two-layer spring improves spring force, plays better buffer function.
