Abstract
The utility model relates to a device for a motor jackscrew of an oil pumping unit, in particular to a quick portable jackscrew. The quick portable jackscrew is characterized by comprising a jackscrew seat arranged on a sliding rail, wherein a positive screw rod is fixedly arranged on the jackscrew seat; a ratchet spanner and a through hole are arranged at one end of the positive screw rod; the other end of the positive screw rod in threaded connection with a negative screw rod; a negative screw rod nut is arranged at the end part of the negative screw rod; a brake plate is arranged on the negative screw rod nut; and a reverse baffle is arranged at one side of the jackscrew seat. Therefore, the quick portable jackscrew has the beneficial effects of simple structure, small size, light weight and convenience in carrying. The quick portable jackscrew is vertically and rotatably arranged so as not to be influenced by a groove; the general effect is achieved; and by adopting the ratchet spanner as a rocker arm, the rotating speed is improved, the operation time is shortened and the production efficiency of an oil well is improved.
Description
Technical field
The utility model relates to a kind of device of pumping-unit motor jackscrew, particularly a kind of quick portable jackscrew.
Background technology
Motor jackscrew commonly used in the oil recovery is to be used for the pushing tow motor, make the instrument of motor displacement forward or backward, before and after pumping-unit motor is general a jackscrew is installed respectively, preceding jackscrew mainly is to be used for the pushing tow motor, motor is moved backward, thereby make belt tension, back jackscrew is used for adjusting motor front and back displacement rational position, finally makes belt reach the effect of four one lines on two belt pulleys.
The jackscrew model in past is different, base thickness difference, and therefore, at motor slide rail afterbody groove hour, thick base jackscrew can't be installed and used.Common jackscrew when mounted, need block jackscrew by the groove baffle plate below the slide rail, could guarantee that jackscrew does not produce displacement in force process, so just need jackscrew itself can cross groove, just can be put into the precalculated position, and then leading screw pushed up on the motor, so, from the jackscrew frontal plane to the leading screw the motor, just produced the virtual row journey, in use, most leading screw front curvature cause jackscrew to damage and can't use.At present, the pumping-unit motor jackscrew adopts one type substantially, just according to the depth difference of motor slide rail open slot, the jackscrew seat base thickness of making is thin to differ, and the on-the-spot belt of changing also is the often work of operation, because the model difference of used jackscrew, use can not be general, and with crowbar rotation jackscrew once, method of operation is single in addition, be unfavorable for saving time, influence oil well production efficient.
Summary of the invention
The utility model provides a kind of quick portable jackscrew that can use in order to remedy the deficiencies in the prior art on the different slide rail of the open slot degree of depth.
The utility model is achieved by the following technical solution:
A kind of quick portable jackscrew, its special character is: comprise the jackscrew seat that is installed on the slide rail, be installed with positive leading screw on the jackscrew seat, positive leading screw one end is provided with ratchet spanner and through hole, the positive leading screw other end anti-leading screw that has been threaded, the end of anti-leading screw is provided with anti-feed screw nut, and anti-feed screw nut is provided with keep plate, and jackscrew seat one side is equipped with reverse baffle plate.
The jackscrew seat is fixed by fixed screw mounting panel and fixed screw and slide rail.
Positive leading screw is provided with internal thread, and anti-leading screw is provided with external screw thread, and internal thread cooperates with external screw thread and is connected.
Rely on fixed screw and the oppositely effect of baffle plate, can locate arbitrarily, reduced the loss of travel of leading screw, thereby increased the service life.
Therefore, the beneficial effects of the utility model are: this quick portable jackscrew, and simple in structure, volume is little, in light weight, be convenient for carrying, adopt vertical rotation to install, be not subjected to the influence of groove, reached general effect, adopted ratchet spanner as rocking arm, velocity of rotation is fast, shorten the operating time, improved oil well production efficient.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 looks schematic diagram for master of the present utility model;
Fig. 2 looks schematic diagram for a left side of the present utility model;
Fig. 3 is a schematic top plan view of the present utility model.
Among the figure, 1 jackscrew seat, 2 positive leading screws, 3 ratchet spanneres, 4 through holes, 5 fixed screws, 6 anti-leading screws, 7 anti-feed screw nuts, 8 keep plates, 9 fixed screw mounting panels, 10 reverse baffle plates.
Embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises the jackscrew seat 1 that is installed on the slide rail, be installed with positive leading screw 2 on the jackscrew seat 1, positive leading screw 2 one ends are provided with ratchet spanner 3 and through hole 4, the positive leading screw 2 other ends anti-leading screw 6 that has been threaded, the end of anti-leading screw 6 is provided with anti-feed screw nut 7, anti-feed screw nut 7 is provided with keep plate 8, jackscrew seat 1 one sides are equipped with reverse baffle plate 10, jackscrew seat 1 is fixed with slide rail by fixed screw mounting panel 9 and fixed screw 5, positive leading screw 2 is provided with internal thread, anti-leading screw 6 is provided with external screw thread, and internal thread cooperates with external screw thread and is connected.
Adopt quick portable jackscrew of the present utility model, during use, above slide rail, install downward vertically, utilized the reverse squeezing action on screw and slide rail plane, all can locate, on the deep mixed slide rail of open slot, can use from any one position.When positive leading screw 2 rotates, make the anti-leading screw 6 of anti-feed screw nut 7 backward rotation, adjust distance by anti-feed screw nut 7, keep plate 8 can prevent that anti-feed screw nut 7 from rotating.Owing to adopted rotation to install, therefore can on the slide rail of various oil pumpers, use, be not subjected to the influence of groove, reached general effect.Ratchet spanner 3 itself has agility, and simultaneously front end has the left-hand thread device, in the process on top, and the right-hand thread certain distance that advances, left-hand thread is the back-off certain distance also, has increased by one times effect.Both can pass through ratchet spanner 3 quick precession leading screws during use, also crowbar can be stretched in the through hole 4, and use the crowbar lengthening arm of force to carry out precession, play effect efficiently.Therefore, the beneficial effects of the utility model are: this quick portable jackscrew, and simple in structure, volume is little, in light weight, be convenient for carrying, adopt vertical rotation to install, be not subjected to the influence of groove, reached general effect, adopted ratchet spanner as rocking arm, velocity of rotation is fast, shorten the operating time, improved oil well production efficient.
