Description

Technical Field

[0001] This utility model belongs to the field of mechanical manufacturing technology and relates to a wrench used for installing and disassembling unions for well logging blowout prevention equipment. Background Technology

[0002] Well logging blowout preventers (BOPs) are critical safety devices used in oil and gas exploration and development to prevent blowouts. During well logging operations, to ensure the safe operation of logging instruments inside the wellbore and to prevent oil and gas leakage at the wellhead, multi-stage high-pressure BOPs must be installed at the wellhead. Because the various BOPs are connected by junction threads, a wrench is required for installation and removal. However, existing wrenches cannot fully meet the needs of equipment installation and removal at well logging sites, affecting operational efficiency and personnel safety. Especially during well logging operations, operators often need to work on wellhead platforms more than 3 meters above the ground; tool damage and slippage can cause injury to operators due to reaction forces.

[0003] For example, Chinese invention patent application CN106312885A discloses a tightening and disassembly tool to prevent impact damage, including a hook-shaped wrench and a positioning screw. The hook-shaped wrench includes an arc segment and a straight shank segment, which are smoothly connected. A cylindrical pin protrudes from the inner arc of the arc segment near the straight shank segment. The axis of the cylindrical pin is collinear with the axis of the straight shank segment, and the axis of the straight shank segment passes through the center of the inner arc of the arc segment. The other end of the arc segment has a mounting hole, the axis of which passes through the center. The axis of the mounting hole and the axis of the cylindrical pin correspond to two holes on the end cap, respectively. The mounting hole is a threaded hole that engages with the external thread of the positioning screw, allowing the positioning screw to pass through the mounting hole. The diameter of the inner arc of the wrench's arc segment is larger than the diameter of the end cap to be assembled. Although this tightening and disassembly tool can install and disassemble the parts, it requires manual visual inspection to insert the protruding cylindrical pin and the positioning screw into the outer arc hole of the end cap for positioning. Therefore, this tightening and disassembly tool is not suitable for high-altitude operations when operators are under high mental stress, as it would increase the intensity of labor. In addition, this tightening and disassembly tool requires tightening and disassembling through cylindrical pins, positioning screws, and the outer arc hole of the end cap, which is a point contact method. This cannot solve the problem of tool slippage under high pressure torque during high-altitude logging operations, which could easily cause operators to fall from heights. Utility Model Content

[0004] The purpose of this utility model is to provide a wrench for installing and removing unions used in well logging blowout preventer equipment, so as to assist operators in avoiding complete reliance on visual judgment and repeated adjustment of the wrench angle when installing and removing unions used in well logging blowout preventer equipment, and to quickly and reliably complete the positioning, installation and removal of the wrench and the union positioning hole.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A wrench for installing and removing a blowout preventer using a union in well logging, comprising a wrench body, the wrench body including a handle and an arc-shaped hook connected to one end of the handle; A fixing plate is fixed on both the inner arc surface near the handle and the inner arc surface away from the handle of the arc-shaped hook. The fixing plate is perpendicular to the plane formed by the wrench body. The side of the fixing plate away from the arc-shaped hook is an inner arc surface that matches the outer arc surface of the union. The fixed plate has symmetrical threaded holes on the sides of both ends perpendicular to the wrench body, and press-fit positioning plunger screws are threaded into the threaded holes.

[0006] As a limitation, the central axis of the fixed plate passes through the center of the inner arc surface of the arc-shaped hook.

[0007] As a second limitation, the length of the plane perpendicular to the fixed plate and the wrench body is equal to the length between the two end faces of the union.

[0008] As a further limitation, the two ends of the plane perpendicular to the plane formed by the fixed plate and the wrench body are fixed with limiting plates, and the limiting plates protrude towards the inner arc surface of the fixed plate.

[0009] As a third limitation, the press-fit locating plunger screw includes a bolt, a lock nut, a compression spring, and a plunger screw; The bolt includes a head and a screw. The end of the screw away from the head is hollow, forming an open cavity. The compression spring is built into the cavity. One end of the compression spring is fixedly connected to the inside of the cavity, and the other end of the compression spring is fixedly connected to the plunger screw. After the bolt and the locking nut are threaded together, they are threaded together with the threaded hole on the fixing plate, with the plunger screw facing the arc-shaped surface of the fixing plate.

[0010] As a fourth limitation, the arc-shaped hook and handle are seamlessly integrated.

[0011] As a fifth limitation, the arc of the said arc-shaped hook is 90°.

[0012] The technological advancements achieved by this invention compared to existing technologies, due to the adoption of the aforementioned technical solution, are as follows: (1) This utility model includes a wrench body, which includes a handle and an arc-shaped hook head connected to one end of the handle; a fixing plate is fixed on the inner arc surface of the arc-shaped hook head near the handle and on the inner arc surface away from the handle. The fixing plate is perpendicular to the plane formed by the wrench body. The side of the fixing plate away from the arc-shaped hook head is an inner arc surface that matches the outer arc surface of the union. Symmetrical threaded holes are provided on the sides of the two ends of the fixing plate that are perpendicular to the wrench body. A press-fit positioning plunger screw is connected to the threaded hole. By adapting and fitting the inner arc surface of the fixing plate to the outer arc surface of the union, the friction area between this utility model and the union is increased, the point contact mode of conventional hook wrenches during operation is changed, the probability of the wrench slipping after being subjected to force is reduced, and damage to the wrench is avoided. (2) In this utility model, the length of the plane formed by the fixed clamping plate and the wrench body in the vertical direction is equal to the length between the two end faces of the union. The two ends of the plane formed by the fixed clamping plate and the wrench body in the vertical direction are fixed with limiting clamping plates, and the limiting clamping plates protrude towards the inner arc surface of the fixed clamping plate. Through the cooperation of the fixed clamping plate and the limiting clamping plate, the two end faces of the union can be wrapped in the space formed by the fixed clamping plate and the limiting clamping plate, which enhances the clamping stability and further reduces the probability of tool slippage. (3) The present invention has through threaded holes on the sides of the two ends of the fixed plate perpendicular to the wrench body. The threaded holes are connected to press-fit positioning plunger screws. The press-fit positioning plunger screws include bolts, lock nuts, compression springs and plunger screws. By using press-fit positioning plunger screws, when the operator rotates the wrench body, when the plunger screw encounters the union positioning hole, the plunger screw will automatically pop out and lock into the positioning point under the action of the internal compression spring. This changes the conventional hook wrench operation mode that relies on manual visual judgment and repeated adjustment of the tool angle to realize the insertion of the cylindrical pins and positioning screws at both ends of the tool into the outer arc hole of the end cap for positioning. This greatly reduces labor intensity and improves operation efficiency. (4) This utility model is designed for positioning holes of different depths in well logging blowout prevention equipment. The position of the press-fit positioning plunger screw on the fixing plate can be adjusted by adjusting the bolt and locking nut on the press-fit positioning plunger screw, thereby realizing the adjustment of the plunger screw length to meet the positioning and fixing requirements.

[0013] In summary, this utility model is applicable to the installation and disassembly of unions used in well logging blowout prevention equipment. It can quickly and reliably complete the positioning, installation, and disassembly between the wrench and the union positioning hole, and enhance the clamping stability of the tool and equipment to prevent slippage.

[0016] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] Example: A wrench for installing and removing a blowout preventer (BOP) device using a union. like Figure 1 and Figure 2 As shown, this embodiment is a wrench for installing and removing a blowout preventer in well logging using a union. It includes a wrench body, a handle 1, and an arc-shaped hook 2 connected to one end of the handle 1. The arc-shaped hook 2 and the handle 1 are smoothly connected in one piece, which facilitates installation and removal operations by the operator.

[0018] A fixing plate 3 is fixedly mounted on both the inner arc surface of the arc-shaped hook head 2 near the handle 1 and the inner arc surface of the hook head 2 away from the handle 1. The fixing plate 3 is perpendicular to the plane formed by the wrench body, and the central axis of the fixing plate 3 passes through the center of the inner arc surface of the arc-shaped hook head 2. The central axis of the handle 1 is collinear with the central axis of the fixing plate 3 near the handle 1. The side of the fixing plate 3 away from the arc-shaped hook head 2 is an inner arc surface that matches the outer arc surface of the union 10. By fitting the inner arc surface of the fixing plate 3 against the outer arc surface of the union 10, the friction area with the outer arc surface of the union 10 can be increased.

[0019] In this embodiment, the length of the plane perpendicular to the plane formed by the fixed clamping plate 3 and the wrench body is equal to the length between the two end faces of the union 10, namely the upper end face 11 and the lower end face 12, and the width of the fixed clamping plate 3 is greater than 20mm. Limiting clamping plates 4 are fixed at both ends of the plane perpendicular to the plane formed by the fixed clamping plate 3 and the wrench body, with the limiting clamping plates 4 protruding towards the inner arc-shaped surface of the fixed clamping plate 3. Through the mutual cooperation of the fixed clamping plate 3 and the limiting clamping plates 4, the two end faces of the union 10 can be wrapped within the space formed by the fixed clamping plate 3 and the limiting clamping plates 4, enhancing clamping stability and further reducing the probability of tool slippage.

[0020] In this embodiment, the fixed plate 3 has symmetrical threaded holes on the sides of both ends perpendicular to the wrench body, and the threaded holes are threaded with press-fit positioning plunger screws 5.

[0021] like Figure 3 As shown, the press-fit positioning plunger screw 5 includes a bolt 6, a locking nut 7, a compression spring 8, and a plunger screw 9. The bolt 6 includes a head and a screw rod. The end of the screw rod away from the head is hollow, forming an open cavity. The compression spring 8 is built into the cavity, with one end of the compression spring 8 fixedly connected to the cavity and the other end fixedly connected to the plunger screw 9. After the bolt 6 is threadedly connected to the locking nut 7, it is threadedly connected to the threaded hole on the fixing plate 3. The plunger screw 9 faces the inner arc-shaped surface of the fixing plate 3.

[0022] In this embodiment, when the press-fit positioning plunger screw 5 is threadedly connected to the threaded hole on the fixing plate 3, the end of the bolt 6 connected to the threaded hole does not extend beyond the threaded hole. The distance between the two press-fit positioning plunger screws 5 on the same end of the two fixing plates 3 is equal to the distance between the two positioning holes 13 on the union 10. The positions of the two threaded holes on the same end of the two fixing plates 3 match the positions of the two positioning holes 14 on the union 10, so that the press-fit positioning plunger screw 5 threadedly connected in the threaded hole of the fixing plate 3 matches the position of the positioning hole 13 of the union 10.

[0023] After the two end faces of the union 10 are locked by the fixing plate 3 and the limiting plate 4, when the operator rotates the wrench body, when the plunger screw 9 encounters the positioning hole 13 of the union 10, the plunger screw 9 will automatically pop out and lock into position under the action of the internal compression spring 8. The compression spring 8 in the press-fit positioning plunger screw 5 will cause the plunger screw 9 to automatically extend and retract, and cooperate with the positioning hole 13 of the union 10 for positioning.

[0024] When the compression spring 8 in the press-fit positioning plunger screw 5 is in a free state, one end of the plunger screw 9, which is fixedly connected to the compression spring 8, is located inside the cavity, and the other end of the plunger screw 9 is located outside the cavity. When the plunger screw 9 encounters the positioning hole 13 of the union 10, the plunger screw 9 will automatically pop out. When the compression spring 8 is in a compressed state, the plunger screw 9 can be completely located inside the cavity. During the process of the operator turning the wrench body to find the positioning hole 13 of the union 10, the plunger screw 9 can automatically retract.

[0025] In this embodiment, the arc of the arc-shaped hook 2 can be 90°, corresponding to the two positioning holes 13 set at 90° from the ring 10. The handle 1, the arc-shaped hook 2, the fixing plate 3, the limiting plate 4, and the press-fit positioning plunger screw 5 are all made of metal materials, such as stainless steel.

[0026] like Figure 4 and Figure 5 As shown, the usage process in this embodiment is as follows: When an operator uses the wrench of this embodiment for installing and removing the well logging blowout preventer with a union during high-altitude operations, the inner arc surfaces of the two fixing plates 3 of the wrench are fitted with the outer arc surfaces of the union 10, and the upper end face 11 and lower end face 12 of the union 10 are fitted with the inner side of the limiting plate 4 respectively. The limiting plate 4 holds the two end faces of the union 10 in place. At this time, the outer arc surface, upper end face 11 and lower end face 12 of the union 10 are enclosed in the space formed by the fixing plate 3 and the limiting plate 4. The operator holds handle 1 and rotates it clockwise. The force is transmitted through handle 1 to the arc-shaped hook head 2 and the fixing plate 3. When the two plunger screws 9 of the two press-fit positioning plunger screws 5 on the same side of the two fixing plates 3 meet the positioning hole 13 of the union 10, the plunger screws 9 automatically pop out under the force of the compression spring 8 and are respectively locked in the positioning hole 13 of the union 10, thus completing the position fixing of the wrench. Continue to hold handle 1 and rotate it clockwise. The plunger screws 9 drive the union 10 to rotate, thereby completing the installation of the well logging blowout prevention equipment.

[0027] Conversely, when disassembling the well logging blowout preventer, change the direction of the wrench so that the two press-fit locating plunger screws 5 on the other side of the two fixing plates 3 correspond to the locating holes 13 of the union 10. The outer arc surface, upper end face 11, and lower end face 12 of the union 10 are again enclosed in the space formed by the fixing plates 3 and the locating plates 4 by the fixing plates 3 and the locating plates 4. Rotate the handle 1 counterclockwise to complete the disassembly operation of the well logging blowout preventer.

[0028] It should be noted that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or make equivalent substitutions for some of the technical features.
