The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Referring to figs. 1 to Fig. 6, oil pipe sucker rod of the present utility model is prevented the eccentric wear erection device, comprising: male joint 1, female joint 2 and roller devices 3.Wherein, roller devices 3 is made up of central tube 31 and roller 32, male joint 1 and female joint 2 are the little cylindrical pipe (as shown in Figure 5 and Figure 6) of the big end of an end, the internal thread of the end that the diameter of male joint 1 is big is connected with the external screw thread of an end of central tube 31, the end that the diameter of male joint 1 is little is provided with the external screw thread that is used to connect oil pipe, the internal thread of the end that the external screw thread of the other end of central tube 31 and the diameter of female joint 2 are big is connected, the end that the diameter of female joint 2 is little is provided with the internal thread that is used to connect oil pipe, central tube 31 is a cylindrical pipe, its both ends open place respectively is evenly distributed with 4 grooves 33, by a bearing pin 34 roller 32 (as shown in Figure 3) is installed in each groove 33, roller 32 is that its external surface is by the cylindrical roller (as shown in Figure 2) of two ends to the level and smooth depression in centre, the roller 32 at central tube 31 two ends surrounds a cylindrical cavity that cooperatively interacts with sucker rod (as shown in Figure 3 and Figure 4), when sucker rod in the oil pumping process, forms rolling friction between sucker rod and the roller 32 in oil pipe.Certainly, the utility model does not limit the number of rollers that the every end of central tube is installed, and the roller that for example every end is installed also can be 3 or 5.
During use, the anti-eccentric wear erection device of oil pipe sucker rod of the present utility model is connected sucker rod and the serious position of oil pipe eccentric wear, i.e. rod sag position, when crooked position had many places, the everywhere all will be installed this oil pipe sucker rod and be prevented the eccentric wear erection device.The concrete installation is that male joint with the anti-eccentric wear erection device of oil pipe sucker rod is connected with a tubing round thread, the female joint that the oil pipe sucker rod is prevented the eccentric wear erection device then with being threaded of another oil pipe.Like this, when in the oil pumping down stroke, the roller that the athletic meeting of sucker rod at its bending place drives the anti-eccentric wear erection device of oil pipe sucker rod rolls, and produces rolling friction with roller, has avoided the sliding friction of sucker rod at its bending place and oil pipe.
With reference to figure 3 and Fig. 4, the position of central tube 3 two ends respective slot 33 differs 45 °.The cylindrical cavity that the staggered like this roller 32 that can make central tube 3 two ends surrounds groove can not occur, has further reduced the friction between anti-eccentric wear erection device of oil pipe sucker rod and the sucker rod.
With reference to figure 1, on the central tube 31 with the junction of male joint 1, and respectively be provided with two trip bolts 35 up and down in junction on the central tube 31 with female joint 2, be used to prevent that male joint, female joint are loosening with being threaded of roller devices; And in order to prevent that crude oil from revealing, on the central tube 31 with the position, joint of male joint 1, and respectively have two grooves 38 at position, joint on the central tube 31 with female joint 2, be provided with a sealing mat 36 in each groove 38.In addition, also be provided with the locating ring 37 of spacing male joint 1 and female joint 2 on the central tube 31.
The anti-eccentric wear erection device of oil pipe sucker rod of the present utility model is connected sucker rod and the serious position of oil pipe eccentric wear, it is the rod sag position, like this, when in oil pumping process, form rolling friction between the roller in the anti-eccentric wear erection device of the knee of sucker rod and oil pipe sucker rod, thereby prevented the sliding friction of sucker rod and oil pipe, the friction of sucker rod has bigger decline than the wear extent that sliding friction produces, thereby prolonged R a T application life, improved oil recovery efficiency, reduced cost for oil production.
Embodiment recited above is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; design under the spiritual prerequisite not breaking away from the utility model; various distortion and improvement that the common engineers and technicians in this area make technical solutions of the utility model all should fall in the definite protection domain of claims of the present utility model.
