Abstract

The utility model relates to a mechanical drive device, in particular to a steel wire pushing device used in oil well work. The technical proposal of the device is that the two sides of a horizontal fixed bolster 11 are respectively coaxially fixed with a gear 2 and a squeegee roller 1 via two groups of bearing bridge 7, wherein one gear shaft 3 is connected with a power take-off drive shaft, the two gears 2 are occluded with each other, the periphery of the squeegee roller 1 is provided with a groove matching with the radius of a steel wire, the two squeegee rollers matching with each other press the steel wire in the groove. The utility model makes uses of mechanical pushing method to send the steel wire into the oil well, thereby avoiding the danger of manual operation, reducing the labor intensity of workers, improving work efficiency and preventing the occurrence of oil well blowout in construction.

Description

The steel wire pusher

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

Two, background technology: in the oil field oil recovery well testing construction at present, because stratum geological condition difference is big, the individual block water absorbing capacity is poor, needs high pressure water injection, and the plot back pressure that has is big, brings certain degree of difficulty to well testing work.Under the high situation of water injection pressure, it is the counterweight that lengthening weighted lever and lubricator increase steel wire that steel wire carries the practice common under the instrument lower going-into-well, and it is descending to utilize artificial hand to promote steel wire, causes 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 steel wire pusher that utilizes mechanical system to carry out operation.

Technical scheme is: in the both sides of horizontal fixed support 11 by two groups of coaxial respectively gear 2 and squeegee rollers 1 fixed of the support of bearing 7, one of them gear shaft 3 is connected with the power output driving shaft, interlock cooperates between two gears 2, the groove that cooperates with the steel wire radius is arranged on the periphery of squeegee roller 1, after two squeegee rollers 1 cooperate steel wire is squeezed in the groove.Having a guiding trestle 6 to be vertically fixed on the fixed support 11 between two squeegee rollers 1, guiding trestle 6 is provided with the deep-slotted chip breaker that cooperates with squeegee roller 1 with squeegee roller 1 joint portion.Between the gear shaft 3 and the support of bearing 7 by bearing fixing.The support of bearing 7 is fastened on fixed support 11 by stud clip by two supports of bearing.One end of fixed support 11 is stopped with the support of bearing 7 by steady pin 13 and cooperates that the other end is with screw mandrel 9, is with baffle plate 8 and handwheel 10 on the screw mandrel 9 respectively.The bottom of guiding trestle 6 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 steel wire 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.

Five, the specific embodiment:

With reference to accompanying drawing, in the both sides of horizontal fixed support 11 by two groups of coaxial respectively gear 2 and squeegee rollers 1 fixed of the support of bearing 7, one of them gear shaft 3 (can be a motor with power, also can be motor) the output driving shaft connection, interlock cooperates between two gears 2, the groove that cooperates with the steel wire radius is arranged on the periphery of squeegee roller 1, after two squeegee rollers 1 cooperate steel wire is squeezed in the groove, steel wire is pushed downwards by squeegee roller.There is being a guiding trestle 6 to be vertically fixed on the fixed support 11 between two squeegee rollers 1, guiding trestle 6 is provided with the deep-slotted chip breaker that cooperates with squeegee roller 1 with squeegee roller 1 joint portion, the bottom of guiding trestle 6 is processed with piston ring, be with sealing ring in the piston ring, so both can limit the trend of steel wire, can improve the sealing of well head again, prevent under the high situation of oil well pressure blowout to take place.Between the gear shaft 3 and the support of bearing 7 by bearing fixing, the support of bearing 7 is fastened on fixed support 11 by stud clip by two supports of bearing, one end of fixed support 11 is stopped with the support of bearing 7 by steady pin 13 and cooperates that the other end is with screw mandrel 9, is with baffle plate 8 and handwheel 10 on the screw mandrel 9 respectively.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 steel wire extruding force, and power tool is voluntarily under the lower going-into-well.

Certain scheme of the present utility model also can be used in the towage of ground or down-hole reinforcing bar, cable.
