Abstract

The utility model relates to a mechanical drive device, particularly a cable propelling device for oil well operation. The utility model has the technical proposal that both sides of a transverse support frame are symmetrically fixed with two sets of bearing support frames in parallel in vertical direction. Both ends of a bearing support frame are respectively and coaxially fixed with four sets of driven gear wheels and squeezing wheels, wherein, the upper driven gear wheel and the lower driven gear wheel of one side of the bearing support frame are intermeshed with a main drive gear wheel capable of outputting dynamic power. Two sets of the driven gear wheels are engaged and matched in horizontal direction. The peripheries of the four squeezing wheels are provided with grooves which are matched with the radius of the cable. After two squeezing wheels are matched, the cable is squeezed in the grooves. The utility model uses the mechanical propelling method to send the cable into the oil well, solves the danger existing in manual operation, reduces the labor intensity of workers, improves the construction efficiency, and effectively prevents well blowout phenomenon in the construction operation process simultaneously.

Description

The cable pusher

One, technical field: the utility model relates to a kind of mechanical actuation device, the cable pusher that particularly a kind of oil well operation is used.

Two, background technology: the oil field is in oil recovery, well logging, water filling construction at present, because stratum geological condition difference is big, the individual block back pressure is big, and cable is difficult to be lowered into the down-hole, comes certain degree of difficulty for the oil well work zone.Under the high situation of down-hole pressure, the common practice is the counterweight that lengthening weighted lever and lubricator increase cable under the cable lower going-into-well, utilize crane to sling, it is descending that artificial hand promotes cable then, cause staff's labour intensity to improve greatly like this, even the blowout phenomenon takes place, operational danger improves.

Three, summary of the invention: the purpose of this utility model is exactly at the problems referred to above, proposes a kind of cable pusher that utilizes mechanical system to carry out operation.Technical scheme is: fix two groups of supports of bearing in the parallel symmetry in the both sides of lateral frame vertical direction, coaxial respectively four groups of driven gears and the squeegee roller fixed in the two ends of the support of bearing, wherein between the upper and lower driven gear of a side with meshing connection of main drive wheel of power output, interlock cooperates between two groups of driven gears of horizontal direction, the groove that cooperates with the cable radius is arranged on the periphery of four squeegee rollers, after two squeegee rollers cooperate cable is squeezed in the groove.Have a guiding trestle to be vertically fixed on the lateral frame between two groups of squeegee rollers vertically, guiding trestle is provided with the deep-slotted chip breaker that cooperates with squeegee roller with the squeegee roller joint portion.Between the rotating shaft of driven gear and squeegee roller and the support of bearing by bearing fixing.The support of bearing is fastened on lateral frame by stud clip by two supports of bearing.End at lateral frame is fixed with Power Drive Unit, and the output shaft of drive unit is connected with main drive wheel, is with screw mandrel at the other end of lateral frame, is with baffle plate on the screw mandrel respectively and compresses the silk wheel.The bottom of guiding trestle is processed with piston ring, is with sealing ring in the piston ring.

The mode that the utility model utilization machinery pushes is lowered to cable in the oil well, solves the danger that manual operations exists, and has alleviated labor strength, improves efficiency of construction.Simultaneously effectively prevent to occur in the construction operation process blowout phenomenon.

Four, description of drawings:

Fig. 1 is a structure chart of the present utility model;

Fig. 2 is an A-A sectional view among Fig. 1;

Fig. 3 is a B-B sectional view among Fig. 1.

Five, the specific embodiment:

With reference to accompanying drawing 1, parallel symmetry is fixed two groups of supports of bearing 12 in the both sides of horizontal lateral frame 11 vertical direction, the upper/lower terminal of the support of bearing 12 is fixing with the support of bearing 12 with gear shaft 14 by bearing 13 respectively, is fixing driven gear 10 and squeegee roller 4 on the four rooted tooth wheel shafts 14 respectively.With reference to accompanying drawing 3, between the upper and lower driven gear 10 of a side, main drive wheel 9 is installed, main driven wheel 9 and meshing connection between the driven gear 10 up and down.With reference to accompanying drawing 2, interlock cooperates between two groups of driven gears 10 of horizontal direction, and the groove that cooperates with cable 1 radius is arranged on the periphery of four squeegee rollers 4, after two squeegee rollers 4 cooperate cable 1 is squeezed in the groove.Have a guiding trestle 3 to be vertically fixed on the lateral frame 11 between two groups of squeegee rollers 4 vertically, guiding trestle 3 is provided with the deep-slotted chip breaker that cooperates with squeegee roller 4 with squeegee roller 4 joint portions, and guiding trestle 3 tops are provided with pulley 2.The support of bearing 12 is fastened on lateral frame 11 by stud clip by two supports of bearing.End at lateral frame 11 is fixed with power buncher 7 (also can be that common electric machine or motor cooperate gearbox to substitute), the output shaft of buncher is connected with main driven wheel 9, the other end at lateral frame 11 is with screw mandrel 5, is with baffle plate on the screw mandrel 5 respectively and compresses silk wheel 6.This design has made things convenient for processing, installation, the use, particularly handwheel of equipment to cooperate with the adjustment of baffle plate, can adjust the operating pressure between the squeegee roller according to the down-hole pressure situation.After the operation instrument was lowered to the downhole designs position, the adjustment by handwheel and bolt can in time discharge the cable extruding force, and power tool is voluntarily under the lower going-into-well.The bottom of guiding trestle 3 is processed with piston ring, is with sealing ring in the piston ring.So both can limit the trend of cable, can improve the sealing of well head again, and prevent under the high situation of oil well pressure blowout to take place.

Certainly the technical program also can be used in the towage in land cable, steel wire, the reinforcement construction.
