Abstract
A special tool for disassembling and assembling a stator of an oil delivery screw pump is applied to the maintenance of the screw pump in the oil field. The two semicircular steel plates form a cylinder shape oppositely, the outer walls of the opposite edges of the semicircular steel plates are respectively provided with a fixing lug, and a bolt penetrates through a bolt hole of the fixing lug. Inner pads are fixed on the inner walls of the two semicircular steel plates; the outer wall of each semicircular steel plate is welded with an external thread cylinder, the external thread cylinders are connected with internal thread cylinders, and the other ends of the internal thread cylinders are fixed with cylindrical telescopic handles. The effect is as follows: the special tool can be fixed on the outer wall of the screw pump stator, the telescopic handle is pushed to enable the screw pump stator to rotate, the screw pump is convenient to disassemble and assemble, manpower is saved, and the labor intensity of workers is reduced.
Description
Technical field
The specific purpose tool that the utility model uses when relating to oilfield servicing maintenance oil transportation screw pump, particularly a kind of specialized hand operation tool that the oil transportation screw pump stator is fixed.
Background technology
Because the dense oily thermal production well serious temperature of shaking out is higher, the stator wearing and tearing in using kind of oil transportation screw pump are very big, cause the oil transfer pump damage can not oil transportation in the time of seriously, must change screw pump stator.At present, do not have the specific purpose tool of dismounting stator, can only use instruments such as waste and old belt, steel wire rope and pipe wrench during maintenance, it is also very dangerous not only to waste time and energy, and is easy to occur squeezing the accident of hindering finger.
The utility model content
The purpose of the utility model is: a kind of dismounting oil transportation screw pump stator specific purpose tool is provided, can steps up oil transportation screw pump stator outer wall, and during maintain and replace oil transportation screw pump stator, time saving and energy saving, safe and reliable.
The technical scheme that the utility model adopts is: dismounting oil transportation screw pump stator specific purpose tool; Mainly by telescoping handle, internal thread cylinder, external screw thread cylinder, semicircle steel plate, interior pad, fixedly ear and bolt are formed; It is characterized in that: two blocks of semicircle steel plates are formed a cylindrical shape relatively; The relative edge of semicircle steel plate along a fixedly ear is arranged respectively on the outer wall, two fixedly ear be parallel to each other, fixedly on the ear bolt hole is being arranged; In the bolt hole of fixing ear, be installed with bolt, the other end of bolt has nut.On the inwall of two semicircle steel plates, be fixed with interior pad; Perpendicular outer wall is welded with an external screw thread cylinder respectively on the outer wall of two semicircle steel plates, the internal thread cylinder that has been threaded on the threaded circular cylinder outside, and the cylindrical other end of internal thread is fixed with cylindrical telescoping handle.
The beneficial effect of the utility model: the utility model dismounting oil transportation screw pump stator specific purpose tool, can specific purpose tool be fixed on the outer wall of screw pump stator, promote telescoping handle and can make screw pump stator rotation, easy disassembly screw pump.Original once minimum needs five people of dismounting screw pump; After using this specific purpose tool, only need three people just can easily unload screw pump stator at the dismounting screw pump stator, the time also shortened in two hours by original 3～4 hours, had practiced thrift manpower, and safety is guaranteed, and reduces labor strength.
Description of drawings
Fig. 1 is the utility model dismounting oil transportation screw pump stator specific purpose tool structural representation.
Fig. 2 is the vertical view of Fig. 1.
Among the figure, the 1-telescoping handle, 2-internal thread cylinder, 3-external screw thread cylinder, the semicircle steel plate of 4-, pad in the 5-, 6-is ear fixedly, the 7-bolt.
The specific embodiment
Embodiment 1: with a dismounting oil transportation screw pump stator specific purpose tool is example, and the utility model is done further explain.
Consult Fig. 1 and Fig. 2.The utility model dismounting oil transportation screw pump stator specific purpose tool, mainly by telescoping handle 1, internal thread cylinder 2, external screw thread cylinder 3, semicircle steel plate 4, interior pad 5, fixedly ear 6 and bolt 7 are formed,
80 millimeters of the width of dry plate, 8 millimeters of thickness.Two blocks of semicircle steel plates 4 are formed a cylindrical shape relatively, and internal diameter is 100 millimeters.The relative edge of semicircle steel plate 4 along have respectively on the outer wall one fixedly 6, two in ear fixedly ear 6 be parallel to each other, fixedly on the ear 6 bolt hole is being arranged, in the bolt hole of fixing ear 6, be installed with M16 bolt 7, the other end of bolt 7 has the M16 nut.Pad 5 on the inwall of two semicircle steel plates 4, being fixed with.Promptly be fixed with the brake block of 8 millimeters thick, to play the effect of protection stator outer wall at the inboard rivet of semicircle steel plate 4.
The perpendicular outer wall centre position is welded with an external screw thread cylinder 3 respectively on the outer wall of two semicircle steel plates 4.The internal thread cylinder 2 that has been threaded on the threaded circular cylinder 3 outside, the other end of internal thread cylinder 2 is fixed with cylindrical telescoping handle 1, and telescoping handle 1 is a Telescopic handle.
