Description

Technical Field

[0001] This utility model relates to a salvage device, specifically a salvage device for salvaging hydraulic pump parts. Background Technology

[0002] The pump core and foot valve are crucial components of a hydraulic pump. When these components malfunction, they need to be retrieved for later repair and replacement. Currently, the commonly used tool for retrieving pump cores and foot valves is a retrieval cylinder. Existing retrieval cylinders primarily use retrieval slips and an inverted conical slip sleeve to clamp the conical capture head on the pump core or the top of the foot valve. Then, the retrieval cylinder is lifted to retrieve the pump core and foot valve. However, existing retrieval cylinders typically have the following drawbacks in use: (1) After the retrieval cylinder retrieves the hydraulic pump core and the bottom valve, the retrieval cylinder spring always presses the retrieval slip at the minimum position of the inverted conical slip cylinder, causing the retrieval slip to always clamp the capture head. It is difficult to remove the capture head on the hydraulic pump core and the capture head on the bottom valve from the retrieval cylinder. At this time, the retrieval cylinder needs to be completely disassembled and the pressure of the spring needs to be released before the retrieval cylinder can be separated from the capture head. This is time-consuming and laborious, seriously affecting the efficiency of the operation and increasing the labor intensity of the operators.

[0003] (2) After the retrieval tube retrieves the hydraulic pump core and the bottom valve, the viscous crude oil inside the hydraulic pump wellbore will stick to the retrieval slips during the retrieval process. After the retrieval slips successfully clamp the capture head, the retrieval slips will stick to the capture head in the narrow slip tube due to the viscosity of the crude oil. It is difficult to remove the capture head on the hydraulic pump core and the capture head on the bottom valve from the retrieval tube. At this time, the retrieval tube needs to be completely disassembled and the viscous crude oil needs to be cleaned before the retrieval tube can be separated from the capture head. This is time-consuming and laborious, which further seriously affects the efficiency of the operation and increases the labor intensity of the operators. Summary of the Invention

[0004] To address the aforementioned shortcomings in the existing technology, this utility model aims to provide a salvage device for retrieving hydraulic pump accessories, thereby improving operational efficiency and reducing the labor intensity of operators.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a salvage device for salvaging hydraulic pump accessories, comprising a salvage cylinder mechanism, a salvage claw mechanism assembled in the salvage cylinder mechanism capable of clamping the capture head on the hydraulic pump accessory, and a manual adjustment mechanism detachably connected to the salvage claw mechanism, wherein the manual adjustment mechanism can adjust the position of the salvage claw mechanism in the salvage cylinder mechanism so that the salvage claw mechanism releases the capture head on the hydraulic pump accessory.

[0006] As a limitation of this utility model, it also includes an observation and cleaning hole provided on the retrieval cylinder mechanism for manual observation and cleaning of viscous crude oil on the retrieval claw mechanism.

[0007] As a further limitation of this utility model, the retrieval cylinder mechanism includes a retrieval cylinder body and a connecting cylinder threadedly connected to the retrieval cylinder body. The retrieval cylinder body has a clamping cavity and a releasing cavity that can work in conjunction with the retrieval claw mechanism to clamp and release the capture head on the hydraulic pump accessory.

[0008] As a further limitation of this utility model, the front end of the retrieval cylinder body is provided with a guide head component for guiding the capture head on the hydraulic pump accessory into the retrieval cylinder mechanism.

[0009] As a further limitation of this utility model, the connecting cylinder includes a connecting cylinder body threadedly connected to the retrieval cylinder body, a through hole provided on the connecting cylinder body, and a manual adjustment mechanism positioning hole provided on the connecting cylinder body for positioning the manual adjustment mechanism.

[0010] As a further definition of this utility model, the retrieval claw mechanism includes an annular base, multiple retrieval claw units fixed at intervals around the bottom periphery of the annular base, a retrieval claw connecting rod detachably connected to the top of the annular base, a compression spring component sleeved on the retrieval claw connecting rod, and a limiting pin inserted on the retrieval claw connecting rod; when the multiple retrieval claw units are in the clamping cavity position, they can tighten inward to clamp the capture head on the hydraulic pump accessory, and when the multiple retrieval claw units are in the releasing cavity position, they can open outward to release the capture head on the hydraulic pump accessory.

[0011] As a further definition of this utility model, the retrieval claw unit includes a long strip-shaped sheet component and a clamping tooth component fixed to the bottom of the long strip-shaped sheet component.

[0012] As a further limitation of this utility model, the number of individual retrieval claws is six.

[0013] As a further limitation of this utility model, the manual adjustment mechanism includes a retrieval claw positioning rod inserted on the retrieval claw connecting rod, and the retrieval claw positioning rod can cooperate with the positioning hole of the manual adjustment mechanism to position multiple retrieval claws individually in the release cavity.

[0014] As another limitation of this utility model, the retrieval tube mechanism, the retrieval claw mechanism and the manual adjustment mechanism are all made of stainless steel.

[0015] By adopting the above-mentioned technical solution, the beneficial effects achieved by this utility model compared with the prior art are as follows: (1) This utility model adopts a structure combining a retrieval cylinder mechanism, a retrieval claw mechanism and a manual adjustment mechanism. The retrieval claw mechanism can hold the capture head on the hydraulic pump accessory. When in use, you only need to let the retrieval claw mechanism hold the capture head on the hydraulic pump accessory and then lift the utility model upward to retrieve the hydraulic pump accessory. After the hydraulic pump accessory is retrieved by this utility model, you only need to operate the manual adjustment mechanism to let the retrieval claw mechanism release the capture head on the hydraulic pump accessory. The hydraulic pump accessory can be easily and conveniently separated from this utility model, saving time and effort, and effectively improving work efficiency and reducing the labor intensity of operators.

[0016] (2) The present invention is provided with an observation and cleaning hole. When the hydraulic pump accessories are retrieved by the present invention, the operator can observe and clean the sticky crude oil on the retrieval claw mechanism through the observation and cleaning hole. At this time, the retrieval claw mechanism can easily release the capture head on the hydraulic pump accessories, saving time and effort, and can further improve the work efficiency and reduce the labor intensity of the operator.

[0017] (3) The present invention is provided with a guide head component. Under the guidance of the guide head component, the capture head on the hydraulic pump accessory can quickly and accurately enter the retrieval cylinder mechanism, which can improve the convenience and practicality of the present invention.

[0018] (4) The structure of the retrieval cylinder mechanism and the retrieval claw mechanism in this utility model is ingenious and reasonable. Each of the multiple retrieval claw units in the retrieval claw mechanism includes a long strip-shaped plate component and a clamping tooth component made of stainless steel. The long strip-shaped plate component and the clamping tooth component have a certain elastic deformation capability. When the multiple retrieval claw units in the retrieval claw mechanism are located in the clamping cavity position, they can tighten inward to achieve clamping of the capture head on the hydraulic pump accessory. When the multiple retrieval claw units are located in the release cavity position, they can open outward to achieve release of the capture head on the hydraulic pump accessory.

[0019] (5) When multiple retrieval claws are individually positioned in the release cavity in this utility model, the retrieval claw positioning rod can be positioned on the positioning hole of the manual adjustment mechanism. At this time, the retrieval claw mechanism is always in the state of releasing the capture head on the hydraulic pump accessory. At this time, the hydraulic pump accessory can be easily removed from this utility model, which effectively improves the practicality and ease of operation of this utility model.

[0020] (6) The retrieval tube mechanism, retrieval claw mechanism and manual adjustment mechanism in this utility model are all made of stainless steel, which can improve the service life of this utility model.

[0021] In summary, this utility model features an ingenious structural design, ease of use, and strong practicality. After retrieving the hydraulic pump components using this invention, the manual adjustment mechanism allows the retrieval claw mechanism to release the capture head on the hydraulic pump components, easily and conveniently separating the components from the invention. This saves time and effort, effectively improving operational efficiency and reducing operator workload. Furthermore, operators can observe and clean the sticky crude oil on the retrieval claw mechanism through the cleaning hole, allowing for easy release of the capture head from the hydraulic pump components, further saving time and effort and improving operational efficiency while reducing operator workload. This utility model is suitable for use when retrieving hydraulic pump cores and bottom valves. Attached Figure Description

Specifically, in this embodiment, the front end of the retrieval cylinder body 11 has a clamping cavity 12, and the releasing cavity 13 is located at the rear end of the clamping cavity 12. The clamping cavity 12 is an inverted conical cavity, which can cooperate with the outer wall of the multiple retrieval claw units 82 in the tightened state to tighten the multiple retrieval claw units 82 and thus clamp the capture head in the hydraulic pump accessory. The releasing cavity 13 can be adapted to the side wall of the multiple retrieval claw units 82 in the open state to open the multiple retrieval claw units 82 and thus release the capture head in the hydraulic pump accessory. The guide head component 3 has a positive conical cavity, which can guide the capture head in the hydraulic pump accessories into the retrieval cylinder body 11.

Each retrieval claw unit 82 includes a long strip-shaped plate member 821 and a clamping tooth member 822 fixed to the bottom of the long strip-shaped plate member 821. The long strip-shaped plate member 821 and the clamping tooth member 822 have a certain elastic deformation capacity, such as... Figure 5 , Figure 6 As shown, when the front ends of the multiple retrieval claw units 82 in the retrieval claw mechanism 8 are located in the clamping cavity 12, they can tighten inward to clamp the capture head on the hydraulic pump accessory; when the front ends of the multiple retrieval claw units 82 are located in the releasing cavity 13, they can open outward to release the capture head on the hydraulic pump accessory. Furthermore, as... Figure 4 As shown, the inner and outer sides of the clamping tooth member 822 are both inclined surfaces. The inclined surface on the inner side of the clamping tooth member 822 is provided with a right-angled stepped groove. The inclined surfaces on the inner side of multiple clamping tooth members 822 cooperate with each other to guide the capture head into the retrieval claw mechanism 8. The right-angled stepped grooves cooperate with each other to hook the capture head. The inclined surfaces on the outer side of multiple clamping tooth members 822 cooperate with the clamping cavity 12 to make the retrieval claw mechanism 8 firmly clamp the capture head.

[0029] The manual adjustment mechanism includes a retrieval claw positioning rod 4 inserted on the retrieval claw connecting rod 83. The retrieval claw positioning rod 4 can cooperate with the manual adjustment mechanism positioning hole 7 to position multiple retrieval claw units 82 in the release cavity 13.
