Description

Polished rod adjusting device

Technical Field

The application relates to the field of petroleum engineering, in particular to a polished rod adjusting device.

Background

In the oil extraction process, the polish rod can penetrate through a packing box arranged on a joint of the rubber gate and move up and down. After the polished rod moves for a period of time, the polished rod can cause abrasion to the packing in the packing box, so that the abraded packing in the packing box needs to be replaced. However, due to the misalignment of the oil pumping unit foundation, the operation of the wellhead and other reasons, the polished rod may be deflected, so that the polished rod is not aligned with the center of the rubber gate, and therefore, when the packing is replaced, it is difficult to normally install a new packing into the packing box. For this reason, the polished rod needs to be adjusted before the packing is replaced.

In the embodiment of the application, the first holding clamp 1 and the second holding clamp 2 are clamped on the outer wall of the rubber gate, so that the positions of the first holding clamp 1 and the second holding clamp 2 are relatively fixed, and the position of the mounting plate 3 is relatively fixed. And because the rod part 41 of the adjusting screw rod 4 passes through the fourth through hole on the mounting plate 3 and the third through hole on the first pin 7, when the adjusting screw rod 4 is rotated, the hand grip 10 can be driven to move towards the direction close to the polish rod until the hand grip 10 pushes the polish rod to align to the center of the rubber gate. Therefore, the inclination angle of the polished rod can be conveniently and quickly adjusted, and the adjustment efficiency of the polished rod is improved. In addition, tools such as pipe tongs are not needed, and the influence of the proficiency of workers is avoided, so that the operation is stable and safe, the polish rod cannot be damaged, and the sealing performance of the packing box cannot be influenced.

In order to make the technical solutions and advantages of the present application more clear, the following detailed description will be given by means of alternative embodiments.

When the packing in the packing box of installing the joint department at the rubber gate needs to be changed, can embrace the card 1 with the second earlier and embrace the card 2 centre gripping on the outer wall of rubber gate with the second, then embrace the first side 11 of card with the first side 21 of card with the second and be connected, the second side 12 of card is embraced with the second side 22 of card with the second and is connected. Then the packing pressing cap and the gland in the packing box are disassembled, the packing pressing cap and the gland are moved to the upper part of the first rib plate 8, and the packing in the packing box is taken out. Then the handle 5 is rotated to move the adjusting screw rod 4 forward until the first end 42 of the adjusting screw rod abuts against the side surface of the hand grip 10, and then the handle 5 is rotated continuously to drive the hand grip 10 to move towards the direction close to the polished rod through the adjusting screw rod 4 until the hand grip 10 contacts with the rod wall of the polished rod. At this time, the adjusting screw 4 continues to rotate, and the gripper 10 pushes the polish rod to move under the driving of the adjusting screw 4 until the polish rod is aligned with the center of the rubber gate. Then, a new packing is sleeved on the polish rod and placed in the packing box, and then the gland and the packing pressing cap are also moved into the packing box and installed.

The above description is only exemplary of the present application and should not be taken as limiting, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
