Abstract

A kind of Crankpin detaching device. Mainly solve existing instrument easily the screwed hole of two fixed screws of crank pins screw catch to be damaged the problem that operation is wasted time and energy. It is characterized in that: main body has blind hole on (1) between two parties, screw thread is had in blind hole,, there is boss (2) between two parties in blind hole at the end, corresponding between the screwed hole of boss (2) and two fixed screws of crank pins screw catch, there is handle (3) the outer both sides of main body (1). This Crankpin detaching device has not easily by the screwed hole damage of two fixed screws of crank pins screw catch, operates time saving and energy saving feature.

Description

Crankpin detaching device

Technical field:

The utility model relates to oil extraction in oil field oil pumper and keeps in repair instrument used, especially Crankpin detaching device.

Background technology:

In field of oil field oil extraction, oil pumper is important lifting equipment. Because oil pumper operation in the wild for a long time needs repairing. When maintenance crank pins, crank pins need to be taken off from crank with instrument. And the screwed hole of two fixed screws of crank pins screw catch easily damages because reasons in structure exists by existing instrument, the problem that operation is wasted time and energy. The final maintenance efficiency that affects.

Utility model content:

Easily the screwed hole of two fixed screws of crank pins screw catch is damaged the problem that operation is wasted time and energy in order to solve existing instrument. The utility model provides a kind of Crankpin detaching device. This Crankpin detaching device has not easily easily by the screwed hole damage of two fixed screws of crank pins screw catch, operates time saving and energy saving feature.

The technical solution of the utility model is: this Crankpin detaching device comprises main body. Main body has between two parties blind hole, have screw thread in blind hole, in blind hole, have boss between two parties, boss is placed between the screwed hole of two fixed screws of crank pins screw catch at the end, and there is handle the outer both sides of main body.

The utility model has following beneficial effect: this Crankpin detaching device has blind hole between two parties owing to adopting in main body, screw thread is had in blind hole, in blind hole, have boss between two parties, boss is placed between the screwed hole of two fixed screws of crank pins screw catch at the end, and there is the structure of handle the outer both sides of main body. Utilize boss top crank pins end face, because boss is placed between the screwed hole of two fixed screws of crank pins screw catch, and then not fragile crank pins screw thread, it is time saving and energy saving to operate, and structure is simple, finally improves maintenance efficiency. This Crankpin detaching device has not easily by the screwed hole damage of two fixed screws of crank pins screw catch thus, operates time saving and energy saving feature.

Detailed description of the invention:

Below in conjunction with accompanying drawing, the utility model is described in further detail:

As shown in Figure 1, this Crankpin detaching device comprises main body 1. Main body 1 there is between two parties blind hole, internal thread is had in blind hole, on internal thread and crank pins, external screw thread matches,, there is boss 2 between two parties in blind hole at the end, corresponding between the screwed hole of boss 2 and two fixed screws of crank pins screw catch, that is boss 2 is placed between the screwed hole of two fixed screws of crank pins screw catch, and there is handle 3 the outer both sides of main body 1.

During actual use:

Rotate two handles 3 by hand, by internal thread, this Crankpin detaching device is connected with crank pins, boss 2 is placed between the screwed hole of two fixed screws of crank pins screw catch, then knock after this Crankpin detaching device with sledgehammer, crank pins unloads from crank the most at last, namely completes the operation of dismounting crank pins. Because boss 2 is placed between the screwed hole of two fixed screws of crank pins screw catch, thus crank pins screw thread can not be damaged when knocking this Crankpin detaching device, and operate time saving and energy savingly, structure is simple. Operating time saves 50 percent, and serviceability rate reaches absolutely.

Claims

1. a Crankpin detaching device, comprise main body (1), it is characterized in that: main body has blind hole on (1) between two parties, screw thread is had in blind hole,, there is boss (2) between two parties in blind hole at the end, boss (2) is placed between the screwed hole of two fixed screws of crank pins screw catch, and there is handle (3) the outer both sides of main body (1).
