Description

Technical Field

[0001] The utility model relates to the field of oil and gas pipeline cleaning, and particularly relates to a tool for a blind plate of a pig launcher and receiver. Background Art

[0002] The oil and gas pipeline is usually cleaned by a pig launcher and receiver system. The pig launcher and receiver system respectively sets pig launchers and receivers at both ends of the oil and gas pipeline to be cleaned. A pig is put into the pig launcher at the upstream of the pipeline, and the pig is pushed into the oil and gas pipeline by the oil and gas medium. The pig pushes the dirt in the oil and gas pipeline into the downstream pig launcher and receiver. A quick-opening blind plate is arranged at the end of the pig launcher and receiver for placing and taking out the pig. The quick-opening blind plate is provided with a clamping collar to make the quick-opening blind plate in close contact with the pig launcher and receiver, and the clamping collar is locked by a driving rod to ensure the sealing performance of the pig launcher and receiver. When operating personnel carry out pig launching and receiving operations, they need to often rotate the driving rod with a hexagonal cross-section to disassemble and assemble the quick-opening blind plate.

[0003] However, the driving rod is made of copper material and has a low hardness. During long-term use, the edge of the hexagonal head of the driving rod is easy to wear, resulting in that ordinary tools cannot hold the driving rod, causing the quick-opening blind plate of the pig launcher and receiver to not be able to be opened normally, affecting the pigging operation; the procedure for replacing the driving rod is cumbersome and the service life is not long.

[0004] Therefore, there is an urgent need for a technical solution at present to solve the technical problem that the currently used tool cannot hold the driving rod after the driving rod is worn. Summary of the Utility Model

[0029] The following will describe the present utility model in detail with reference to the drawings.

[0030] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0031] Embodiment 1

[0032] As Figures 1 - 4 shown, a tool for the blind plate of the pigging barrel includes a base 1, a sleeve 2 and a snap ring 4. The base 1 is connected to the sleeve 2, and the snap ring 4 is adaptively connected to the outer wall of the sleeve 2; the sleeve 2 is used for sleeving a driving rod;

[0033] A plurality of clamping teeth 5 are provided on the inner wall of the sleeve 2, and the clamping teeth 5 can abut against the driving rod;

[0034] A plurality of notches 21 are provided on the sleeve 2.

[0035] By providing the sleeve 2 on the base 1, when the driving rod is placed in the sleeve 2, the clamping teeth 5 provided on the inner wall of the sleeve 2 can abut against the driving rod; the side wall of the sleeve 2 is provided with notches 21, and a snap ring 4 is adaptively provided on the outer wall of the sleeve 2, so that the snap ring 4 can be hoop-mounted on the outer wall of the sleeve 2 and the side wall of the sleeve 2 is pressed towards the inside of the sleeve, thereby increasing the abutting force of the clamping teeth 5 on the driving rod and enabling the driving rod to be limited and fixed in the sleeve 2; when the base 1 rotates, the driving rod can be driven to rotate, facilitating the operator to open and close the quick-opening blind plate.

[0036] Specifically, the base 1 is a cylindrical structural member. A sleeve 2 and a connection groove 6 are respectively provided at opposite ends of the cylindrical structural member. The connection groove is a T-shaped groove, and the sleeve 2 is a cylindrical barrel, such that the axis of the cylindrical barrel is collinear with the axis of the cylindrical structural member; the cylindrical structural member and the cylindrical barrel are an integrally formed structural member. The cylindrical barrel is provided with an opening 23, and a notch 21 penetrates through the opening 23. The driving rod can be inserted into the cylindrical barrel from the opening 23. The notch 21 is arranged along the axial direction of the cylindrical barrel and extends to the end face of the cylindrical structural member.

[0037] Specifically, four notches 21 are provided. The distance between adjacent notches 21 is equal. The four notches 21 are annularly arranged on the cylindrical barrel centered on the axis of the cylindrical barrel. The four notches 21 equally divide the cylindrical barrel into four petal-shaped walls 22; the petal-shaped walls 22 have a certain deformation ability. The petal-shaped walls 22 can increase the internal space of the cylindrical barrel by moving away from the internal space of the cylindrical barrel, thereby making it easier to insert the driving rod into the cylindrical barrel; the petal-shaped walls 22 can, by shifting towards the inner wall space of the cylindrical barrel, cause the clamping teeth 5 to press against the driving rod, limiting and fixing the driving rod within the cylindrical barrel and making it difficult for the driving rod to have relative displacement with the cylindrical barrel.

[0038] Specifically, the snap ring 4 is threadedly connected to the cylindrical barrel. By threadedly connecting the snap ring 4 to the outer wall of the cylindrical barrel, the snap ring 4 can adjust the magnitude of the clamping force on the driving rod.

[0039] Specifically, a number of clamping teeth 5 are circumferentially arranged on the inner wall of the cylindrical barrel centered on the axis of the cylindrical barrel, such that multiple clamping teeth 5 can jointly abut against the outer wall of the driving rod in different orientations, thereby preventing the driving rod from slipping.

[0040] Specifically, an operating rod 3 is provided on the side of the cylindrical structural member away from the sleeve 2. The operating rod 3 is detachably connected to the cylindrical structural member. One end of the cylindrical structural member is provided with the sleeve 2 and the other end is provided with the operating rod 3; a T-shaped structural member is provided as a connection portion 7 at the end of the operating rod 3. By fitting and embedding the T-shaped structural member into the T-shaped groove and using the lever principle, the operating rod 3 can more easily rotate the cylindrical structural member; the T-shaped groove is located in the middle of the end face of the cylindrical structural member and penetrates through the side wall of the cylindrical structural member.

[0041] Specifically, the T-shaped structural member is composed of a cross bar 72 and a vertical bar 71. The middle of the cross bar 72 is connected to the end of the vertical bar 71. The vertical bar 71 is perpendicularly connected to the end of the operating rod 3; using the lever principle to make it easy to rotate the cylindrical structural member.

[0042] Specifically, the clamping teeth 5 are convex rib structural members. The convex rib structural members are triangular prisms, and the edges of the triangular prisms abut against the driving rod; making it difficult for the driving rod to slide.

[0043] Specifically, the cylindrical structural member and the sleeve 2 are integrally formed by casting, which can bear greater forces and improve the durability and service life of the sleeve 2.

[0044] For a tool for the receiving and sending barrel blind plate in this embodiment, during use, unscrew the snap ring 4, place the driving rod into the cylindrical barrel, make the clamping teeth 5 on the inner wall of the cylindrical barrel abut against the outer wall of the driving rod, and then insert the snap ring 4 into the cylindrical structural member and screw it towards the cylindrical barrel side, so that the snap ring 4 is clamped on the outer wall of the cylindrical barrel, causing the side wall of the cylindrical barrel to squeeze against the driving rod, increasing the force between the clamping teeth 5 and the driving rod, and limiting the driving rod by the cylindrical barrel; by the adaptability connection between the operating rod 3 and the T-shaped groove, the operating rod 3 drives the base 1 to rotate, so that the driving rod can rotate.

[0045] Embodiment 2

[0046] For a tool for the receiving and sending barrel blind plate in this embodiment, its structure is substantially the same as that of Embodiment 1. The difference from Embodiment 1 is that the number of notches 21 is set to more than four.

[0047] The more the number of notches 21 is set, the better the clamping effect of the snap ring 4 on the driving rod, and the driving rod can be fixed more firmly; however, the more the number of notches 21 is set, the smaller the structural volume of a single petal-shaped wall 22 and the lower the structural strength of the petal-shaped wall 22; during actual setting, the number of notches 21 should be designed according to the magnitude of the force required for the driving rod to rotate.

[0048] Embodiment 3

[0049] For a tool for the receiving and sending barrel blind plate in this embodiment, its structure is substantially the same as that of Embodiment 1. The difference from Embodiment 1 is that the sleeve 2 and the base 1 are detachably connected.

[0050] By replacing the sleeves 2 of different specifications and sizes, the tool for the receiving and sending barrel blind plate can be applied to driving rods of different specifications.

[0051] Embodiment 4

[0052] For a tool for the receiving and sending barrel blind plate in this embodiment, its structure is substantially the same as that of Embodiment 1. The difference from Embodiment 1 is that the operating rod 3 and the base 1 are integrally formed structural members.

[0053] Preferably, a connecting hole is opened on the side wall of the cylindrical structural member, the axis of the connecting hole intersects with the axis of the cylindrical structural member, and the operating rod 3 can be adaptably inserted into the connecting hole.

[0054] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
