Abstract

The utility model provides a crank pin removing device for an oil sucking machine, which belongs to a maintenance tool of an oil field oil sucking machine and is formed by connecting a slide rod, a slide hammer, a centralizing joint and a stop block, wherein the stop block is fixed at one end of the slide rod, the other end of the slide rod is provided with screw threads, the slide hammer is provided with a center hole and is sheathed on the slide rod in a penetrating way, the outer side of the slide hammer is provided with an oval groove, one end of the centralizing joint is provided with internal screw threads connected with screw threads of a crank pin, and the other end of the centralizing joint is provided with reducing internal screw threads connected with external screw threads of the slide rod. When the crank pin removing device is used, the fixed screw cap of the crank pin is dismounted, and the centralizing joint is arranged on screw threads arranged on the crank pin by an inner hexagonal spanner. The slide hammer is sheathed on the slide rod in a penetrating way, and the slide rod is connected with the centralizing joint through the screw threads. Operators hold the oval groove arranged at the outer side of the slide hammer by two hands for fast pushing the slide hammer, so the slide hammer keeps a certain force to continuously knock at the centralizing joint, the knocking force is continuously transmitted to the crank pin through the centralizing joint until the crank pin is loose.

Description

A kind of oil pumping machine crank pin withdrawing device
One, technical field: the utility model relates to the maintenance tool of oil-field oil pumper, especially a kind of oil pumping machine crank pin withdrawing device.
Two, technical background: carrying out oil pumper when transferring stroke and changing the crank-pin operation at present, operating personnel are with sledgehammer when unloading crank pins, it are pounded out, and in the Wen Nan oil field even other oil fields this phenomenon of ubiquity all.In order to use hammer convenient working personnel operation, there is not the high empty position of barrier around must standing in, personal safety can not get ensureing, damages crank-pin in the unloading process easily, the operating time is at least more than 35 minutes.Run into obstinate situation, and sometimes because the other strength of pin is difficult to pound out, moves back this link of pin and made great difficulty, process two or three hours at least at most time half a day, has not only been wasted manpower, time, has also influenced rate when driving a well.
Three, summary of the invention: the purpose of this utility model provides a kind of simple in structure, easy to operate, reliable, practical a kind of oil pumping machine crank pin withdrawing device, the purpose of this utility model is to realize like this, it be by by slide bar, sliding hammer, set upright joint and block is formed by connecting, block is fixed on an end of slide bar, and the other end of slide bar has screw thread; Sliding hammer is provided with centre bore, is set on the slide bar, and sliding hammer arranged outside has oval-shaped groove; Set upright joint one end and be provided with internal thread, be threaded with crank-pin, the other end is provided with the undergauge internal thread and is connected with the slide bar external screw thread.
During use the crank-pin hold-doun nut is pulled down, will be set upright the connector by using allen wrench and be installed on screw thread on the crank-pin.To slide hammer and be set on the slide bar, slide bar is set upright joint by screw thread and is connected.Operating personnel with the hands catch the sliding hammer outside to be provided with oval Baltimore groove and promote sliding hammer fast, make it keep certain strength constantly to clash into and set upright joint, and impact constantly passes to crank-pin until loosening by setting upright joint.
Advantage of the present utility model: by using this device: 1, reduce staff's physical demands greatly.2, the shortening time is changed the time greatly.3, avoided personal injury, safety is guaranteed.4, reduce material consumption, avoid the damage of pin and scrap.5, easy for installation, simple to operate.6, reduced and stopped the well time, increased rate when driving a well, guaranteed to produce on the crude oil.
Four, description of drawings: Fig. 1 is a kind of structural representation of oil pumping machine crank pin withdrawing device, among the figure 1, slide bar 2, sliding hammer 3, set upright joint 4, block
Five, the specific embodiment: embodiment 1, the utility model by slide bar 1, sliding hammer 2, set upright joint 3, block 4 is formed by connecting, block 4 is fixed on an end of slide bar 1, sliding hammer is set on the slide bar; Set upright joint one end and be threaded with crank-pin, the other end is connected with the slide bar external screw thread.
One end of embodiment 2, slide bar 1 has screw thread.
Embodiment 3, sliding hammer 2 are provided with centre bore, and sliding hammer 2 arranged outside have oval-shaped groove.
Embodiment 4, set upright joint 3 one ends and be provided with internal thread, the other end is provided with the undergauge internal thread.
