Description

Technical Field

[0001] The utility model relates to the field of maintenance tools, in particular to a portable tool for repairing a petroleum plunger pump. Background Art

[0002] During use, the plunger pump relies on the reciprocating movement of the plunger to apply continuous squeezing to the medium, thereby inputting mud or clean water into the drilling well to achieve the purpose of cooling the drill bit, removing the cut rock cuttings and transporting them to the surface.

[0003] When disassembling and repairing a plunger pump, a sliding hammer is usually used as a tool. The sliding hammer includes a guide part and an impact part. The plunger can be pulled out by the pulling force generated by the impact.

[0004] When the existing sliding hammer is transferred, the bumpy road surface may cause the impact part to hit itself, causing the sliding hammer to damage the transfer device. If it is carried manually, the impact force may cause inconvenience in carrying. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1 to Figure 4 In an embodiment of the utility model, a portable tool for repairing a petroleum plunger pump comprises a hollow rod 1, a connector 2 is integrally formed at one end of the closed end of the hollow rod 1, a hollow groove 9 is provided inside the hollow rod 1, a striking head 10 is slidably connected to the inner wall of the hollow groove 9, a pumping rod 4 is integrally formed at one end of the striking head 10 and penetrates to the outside of the other end of the hollow rod 1, a movable plate 5 is fixedly connected to one end of the pumping rod 4 located outside the hollow rod 1, and a handle 6 is integrally formed at one end of the movable plate 5 away from the pumping rod 4; a fixed plate 3 is fixedly installed at the outer periphery of the open end of the hollow rod 1, and a limiting mechanism for limiting the movable plate 5 is installed on the fixed plate 3, and the limiting mechanism is used to limit the movable plate 5 to an initial position.

[0021] In this embodiment: First, when using the tool to disassemble the plunger, the pump housing is disassembled first, and then the connection position between the plunger and the driving device is disassembled, and then the connecting head 2 is threadedly connected to the screw hole opened at one end of the plunger, and then the handle 6 is rotated, and the handle 6 drives the movable disk 5 to rotate, and the movable disk 5 is misaligned with the limiting mechanism, and then the handle 6 can be pulled, and the handle 6 drives the pumping rod 4 to move in the hollow groove 9 through the movable disk 5, and the moving pumping rod 4 drives the impact head 10 to impact the inner wall of the hollow groove 9, and the impacted hollow groove 9 drives the hollow rod 1 to move, and the moving hollow rod 1 applies a pulling force to the plunger through the connecting head 2, and the pulling force can assist in pulling the plunger out of the plunger cylinder.

[0022] Please refer to Figure 3 and Figure 4 The limiting mechanism includes a sliding groove 11 provided inside the fixed disk 3, and a sliding rod 12 is slidably connected to the inner wall of the sliding groove 11. One end of the sliding rod 12 penetrates the outside of the fixed disk 3 and is connected to the limiting block 8. The vertical section of the limiting block 8 is a "C"-shaped structure rotated 90 degrees. A receiving groove 7 for accommodating a vertical plate of the limiting block 8 is provided at one end of the fixed disk 3 close to the movable disk 5. A notch 13 is provided on the movable disk 5. The inner wall of the notch 13 is consistent with the outer wall of the vertical plate on one side of the limiting block 8. A rubber friction pad is fixedly connected to the vertical plate on one side of the limiting block 8 close to the inner wall of the receiving groove 7.

[0023] In this embodiment, when the movable plate 5 reciprocates, the reciprocating movable plate 5 will move the vertical plate on one side of the limit block 8. At this time, the vertical plate on one side of the limit block 8 is impacted and enters the receiving groove 7. The limit block 8 will not restrict the movement of the fixed plate 3. At this time, the moving limit block 8 drives the sliding rod 12 to move along the sliding groove 11.

[0024] When the mutual restriction between the movable plate 5 and the limit block 8 is released, the handle 6 is turned, and the handle 6 drives the movable plate 5 to rotate. At this time, the movable plate 5 drives the notch 13 to rotate until the notch 13 is aligned with a vertical plate on one side of the limit block 8. At this time, the movable plate 5 and the limit block 8 are misaligned, and the movable plate 5 can be pulled to reciprocate.

[0025] When the tool is not used, the vertical plate on the other side of the limit block 8 is pushed, and the vertical plate on the side pushes the sliding rod 12 to move along the sliding groove 11 until the limit block 8 is reset, and then the notch 13 is aligned with the notch 13 on the movable plate 5 again, and then the movable plate 5 is pushed to reset by the handle 6 until the movable plate 5 fits with the fixed plate 3, and then the movable plate 5 is driven to rotate by the handle 6, at this time, the notch 13 is misaligned with the vertical plate on one side of the limit block 8, and the limit of the movable plate 5 is completed;

[0026] Since a rubber friction pad is fixed on a vertical plate on one side of the limiting block 8 , the rubber friction pad can exert a certain friction force on the moving disk 5 during the rotation of the moving disk 5 to prevent the moving disk 5 from rotating and limit the moving disk 5 .

[0027] Please refer to Figure 4 The opening inner diameter of the sliding groove 11 is smaller than the non-opening inner diameter of the sliding groove 11 , the wide diameter of the sliding rod 12 is equal to the non-opening inner diameter of the sliding groove 11 , and the narrow diameter of the sliding rod 12 is equal to the opening diameter of the sliding groove 11 .

[0028] In this embodiment, this design can prevent the sliding rod 12 from being disengaged from the sliding groove 11 .

[0029] Please refer to Figure 2 The diameter of the impact head 10 is greater than the diameter of the draw rod 4 , the outer diameter of the impact head 10 is equal to the non-open inner diameter of the hollow groove 9 , and the diameter of the draw rod 4 is equal to the open inner diameter of the hollow groove 9 .

[0030] In this embodiment, during the reciprocating movement of the draw rod 4, the impact head 10 can impact the inner wall of the hollow groove 9, thereby exerting a pulling force on the plunger.

[0031] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
