Abstract
The special safety support for replacing the packing of the pumping well head is applied to supporting the packing pressing cap of the rubber gate when the packing is replaced on the pumping well head in oil field maintenance. A reinforcing steel bar with the diameter of 12mm is bent into a semicircular arc, a hook is bent at two ends of the semicircular arc, and a vertical supporting rod is vertically welded in the middle of a semicircular arc transverse hook; bending the top of the vertical supporting rod into a 90-degree arc; an opening fork is horizontally welded at the end part of the 90-degree arc of the vertical supporting rod. The effect is as follows: the packing pressing cap of the rubber gate can be supported at the upper part of the cross rod fixed on the wall of the polish rod sealing device, and the packing pressing cap of the rubber gate can not slide along the polish rod, so that an operation space is provided for replacing the sealing filler. The defect that the hands of the staff are hurt by the falling of the packing pressing cap of the rubber gate when the packing is replaced by the staff is overcome, and the stable and safe operation of the staff is ensured.
Description
Technical field
The utility model relates to oil recovery technique field, oil field, and particularly a kind of safety operation special tool of oil pumper well head maintenance is that a kind of mouth of pumped oil well changes the special-purpose emergency support of packing.
Background technology
At present, polished rod sealer (rubber gate) is arranged at the top of oil pumper well head device, is the indispensable device of mouth of pumped oil well.Because well mouth of oil well eccentric wear, polished rod be motion repeatedly up and down in polished rod sealer; Secondary seal filler (packing) in the wearing and tearing polished rod sealer; Cause well head to run oil; Therefore, the employee must in time change the packing in the polished rod sealer in the daily production, to prevent that well mouth of oil well from running fry dried food ingredients and giving birth to the well head contamination accident.The employee generally is parked in bottom dead centre with pumping unit horsehead before changing packing, lay down rubber gate packing pressure cap, gate packing pressure cap is twined with iron wire hang on the polished rod eye, or is stuck in pressure cap polished rod bottom with pipe wrench, prevents that pressure cap from gliding to pound hand.These two kinds of measures influence the employee and change the packing operation, can not prevent fundamentally that the pressure cap downslide from injuring employee's hand by a crashing object.
The utility model content
The purpose of the utility model is: provide a kind of mouth of pumped oil well to change the special-purpose emergency support of packing, be fixed on the polished rod sealer, upper support rubber gate packing pressure cap, rubber gate packing pressure cap can not landings, for changing airtight and watertight padding (packing) operating space are provided.
The technical scheme that the utility model adopts is: mouth of pumped oil well changes the special-purpose emergency support of packing; Comprise the horizontal hook of semicircular arc, pin bar, handle and opening fork; It is characterized in that: use diameter to curve a semi arch as the reinforcing bar of 12mm; Symmetry upwards bends a hook respectively at the two ends of semi arch, becomes a horizontal hook of semicircular arc, at pin bar of intermediate vertical welding of the horizontal hook of semicircular arc; On the wall of pin bar, be welded with a handle; Curve 90 degree circular arcs at the pin bar top, the direction of 90 degree circular arcs is identical with the direction of the horizontal hook of semicircular arc; Opening fork of 90 degree arc end part level welding at pin bar; The reinforcing bar that described opening fork employing diameter is 12mm curves the circular arc that diameter is 40mm, and diameter is that the A/F of the circular arc of 40mm is 23mm.
The diameter of described pin bar is 12mm, and the length of pin bar is 650mm, and the 90 degree arc length that the pin bar upper end curves are 170mm.
The use that the summary mouth of pumped oil well changes the special-purpose emergency support of packing.Consult Fig. 2.After rubber gate packing pressure cap 5 dismantled, along carrying certain altitude on the polished rod 6.The horizontal hook 1 of semicircular arc that mouth of pumped oil well is changed the special-purpose emergency support of packing hangs on the cross bar on polished rod sealer 7 walls.Aim at polished rods 6 and be stuck on the polished rod 6 with opening fork 4.Rubber gate packing pressure cap 5 is pressed in the top of opening fork 4.Opening fork 4 supports rubber gate packing pressure cap 5, prevents to glide, and the employee just can relievedly change the packing operation, save labour, safe ready.
The beneficial effect of the utility model: the utility model mouth of pumped oil well changes the special-purpose emergency support of packing; Be fixed on the cross bar on the polished rod seal wall; Rubber gate packing pressure cap can be supported in top; Rubber gate packing pressure cap can not provide the operating space for changing airtight and watertight padding (packing) along the polished rod landing.Overcome the employee when changing packing, the landing of rubber gate packing pressure cap injures the deficiency of employee's hand by a crashing object, guarantees the steady safety operation of employee.
Description of drawings
Fig. 1 is that the utility model mouth of pumped oil well changes the special-purpose emergency support structural representation of packing.
Fig. 2 is the utility model user mode sketch map.
Among the figure, the horizontal hook of 1-semicircular arc, 2-pin bar, 3-handle, 4-opening fork, 5-rubber gate packing pressure cap, 6-polished rod, 7-polished rod sealer.
The specific embodiment
Embodiment 1: changing the special-purpose emergency support of packing with a mouth of pumped oil well is example, and the utility model is done further explain.
Consult Fig. 1.The utility model mouth of pumped oil well changes the special-purpose emergency support of packing, comprises the horizontal hook of semicircular arc 1, pin bar 2, handle 3 and opening fork 4.
Use diameter to curve a semi arch as the reinforcing bar of 12mm, symmetry upwards bends a hook respectively at the two ends of semi arch, becomes a horizontal hook 1 of semicircular arc, at pin bar 2 of intermediate vertical welding of the horizontal hook 1 of semicircular arc; The diameter of pin bar 2 is 12mm, and the length of pin bar 2 is 650mm.On the wall of pin bar 2, be welded with a handle 3, handle 3 adopts the reinforcing bar of diameter 12mm to accomplish.Curve 90 degree circular arcs at pin bar 2 tops, the 90 degree arc length that pin bar 2 upper ends curve are 170mm.The direction of 90 degree circular arcs is identical with the direction of the horizontal hook 1 of semicircular arc; Opening fork 4 of 90 degree arc end part level welding at pin bar 2; The reinforcing bar that described opening fork 4 employing diameters are 12mm curves the circular arc that diameter is 40mm, and diameter is that the A/F of the circular arc of 40mm is 23mm.
