Description

Technical Field

[0001] This utility model relates to the field of tailpipe suspension technology, and in particular to a combined tailpipe suspension structure. Background Technology

[0002] A tailpipe hanger is a downhole tool used to suspend the tailpipe from the upper casing string. It is a casing accessory that enables tailpipe cementing, reduces the weight of the casing during a single run-in of a deep well, improves the load on the drilling rig hoisting system during casing run-in, reduces the flow resistance of the cement slurry, and facilitates safer construction. One type of tailpipe hanger is a combined type, which only requires connecting the large rubber plug, the combined short section, and the connecting pipe of the hanger to use. Finally, the output is carried out through the output pipe.

[0003] When storing, personnel generally do not disassemble the output pipe, but store the output pipe and tailpipe hanger together. The equipment occupies a large space, and personnel are prone to bumping or knocking the output pipe during handling.

[0004] The prior art discloses a combined tailpipe suspension device, in which a protective box is fitted over the output pipe and a buffer pad is installed inside the protective box. The protective box and the buffer pad protect the output pipe and prevent external forces from hitting the protective box. However, the protective box in this application is a cylindrical structure. When protecting the pipe, the protective box needs to be manually fitted onto the outer wall of the output pipe. When removing the protective box, it also needs to be manually removed. Since the gap between the buffer pad inside the protective box and the outer wall of the output pipe is small, there is a large friction force during installation and removal. Therefore, it is inconvenient to install and remove the cylindrical protective box. The installation and removal process is laborious and difficult. Utility Model Content

[0005] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a combined tailpipe suspension structure, in which the first semicircular protective cylinder and the second semicircular protective cylinder are hinged together, so that it can be easily fitted onto the outside of the output pipe for protection by fixing components, and is also easy to remove.

[0006] This utility model provides a combined tailpipe suspension structure, comprising:

[0007] Tailpipe suspension body;

[0008] An output pipe is located at one end of the tailpipe hanger body and is connected to the tailpipe hanger body.

[0009] The protective assembly includes a first semicircular protective cylinder and a second semicircular protective cylinder. One side of the first semicircular protective cylinder is hinged to one side of the second semicircular protective cylinder. The other side of the first semicircular protective cylinder and the other side of the second semicircular protective cylinder are provided with a fixing component. When the first semicircular protective cylinder and / or the second semicircular protective cylinder rotate around the hinge point, the first semicircular protective cylinder and the second semicircular protective cylinder are fastened together to form a cylinder, which is used to sleeve the outside of the output pipe to protect the output pipe.

[0010] An installation component is provided at the connection between the tailpipe suspension body and the protective component, for making the tailpipe suspension body and the protective component detachably connected.

[0011] Furthermore, buffer pads are provided on the inner walls of both the first and second semi-circular protective cylinders.

Each fixing component includes a fixing screw, a fixing block fixedly disposed on the outer wall of the first semicircular protective cylinder, and a fixing seat fixedly disposed on the outer wall of the second semicircular protective cylinder. The fixing seat has a fixing groove facing the fixing block. The two sides of the fixing groove are symmetrically connected to a first fixing hole and a second fixing hole. The fixing block has a through hole. When the first semicircular protective cylinder and the second semicircular protective cylinder are fastened together, the fixing screw passes through the first fixing hole and the through hole in sequence and then inserts into the second fixing hole and is threadedly connected to the second fixing hole.

[0013] Furthermore, the installation assembly includes a positioning post, a positioning seat, and elastic fasteners. The positioning post is fixedly mounted on the tailpipe hanger body, and the positioning seat is fixedly mounted on one end of the first semi-circular protective cylinder near the tailpipe hanger body.

The slider is fixedly connected with a locking block that matches the locking groove. One end of the spring is fixedly connected to the inner wall of the sliding groove, and the other end is fixedly connected to the slider. The elastic force of the spring can push the slider to move in the direction close to the positioning post, so that the locking block is inserted into the locking groove and fixed.

[0015] Furthermore, two sets of elastic fasteners are symmetrically arranged on both sides of the positioning hole at the top of the positioning seat, and two sets of slots corresponding to the elastic fasteners are opened on the outer wall of the positioning post.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0033] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] Please refer to Figures 1-4 The present invention provides a combined tailpipe suspension structure, including a tailpipe suspension body 1, an output pipe 2, a protective component 3, and a mounting component 4.

[0035] The output pipe 2 is located at one end of the tailpipe hanger body 1, and the output pipe 2 is connected to the tailpipe hanger body 1.

[0036] The protective component 3 includes a first semi-circular protective cylinder 31 and a second semi-circular protective cylinder 32. One side of the first semi-circular protective cylinder 31 is hinged to one side of the second semi-circular protective cylinder 32. The other side of the first semi-circular protective cylinder 31 and the other side of the second semi-circular protective cylinder 32 are provided with a fixing component 5. When the first semi-circular protective cylinder 31 and / or the second semi-circular protective cylinder 32 rotate around the hinge point, the first semi-circular protective cylinder 31 and the second semi-circular protective cylinder 32 are fastened together to form a cylinder, which is used to sleeve the outside of the output pipe 2 to protect the output pipe 2.

[0037] Mounting component 4 is located at the connection between tailpipe hanger body 1 and protective component 3, and is used to make tailpipe hanger body 1 and protective component 3 detachably connected.

[0038] In this embodiment, the mounting component 4 is located at the connection between the tailpipe hanger body 1 and the first semi-circular protective cylinder 31. During protection, the first semi-circular protective cylinder 31 is first fitted onto the outer wall of the output pipe 2. Then, the mounting component 4 is used to install the first semi-circular protective cylinder 31 onto the tailpipe hanger body 1, thus achieving the installation and fixation of the protective component 3. Next, the second semi-circular protective cylinder 32 is rotated so that it engages with the first semi-circular protective cylinder 31 to form a cylinder. The fixing component 5 is used to fix the other side of the first semi-circular protective cylinder 31 and the other side of the second semi-circular protective cylinder 32. The cylindrical structure formed by the combination of the first semi-circular protective cylinder 31 and the second semi-circular protective cylinder 32 is integrally fitted onto the outer wall of the output pipe 2 to protect it and prevent damage. The problem of damage caused by collision with the ground during the handling and storage of the output tube has occurred; during disassembly, the first semi-circular protective cylinder 31 and the second semi-circular protective cylinder 32 can be separated by operating the fixing component 5, making it easy to remove the protective component 3; by setting the protective component 3 as a hinged connection between the first semi-circular protective cylinder 31 and the second semi-circular protective cylinder 32, compared with the traditional cylindrical protective box, this application does not move relative to the output tube 2 during installation, and the two sets are not affected by the frictional force generated by relative movement. It can be directly fitted onto the outer wall of the output tube 2, which facilitates the installation of the protective component 3. During disassembly, the first semi-circular protective cylinder 31 and the second semi-circular protective cylinder 32 can be separated by operating the fixing component 5, making it easy to remove the protective component 3. The operation is convenient and labor-saving.

[0039] In a preferred embodiment, such as Figure 2 and Figure 4As shown, buffer pads 33 are provided on the inner walls of both the first semicircular protective cylinder 31 and the second semicircular protective cylinder 32. Specifically, during protection, the first semicircular protective cylinder 31 and the second semicircular protective cylinder 32 form a cylindrical shape and are fitted onto the outer wall of the output pipe 2. The side of the buffer pad 33 closest to the output pipe 2 is in contact with the outer wall of the delivery pipe 2 to buffer the impact of external forces, thus playing a buffering and protective role and preventing the inner walls of the first semicircular protective cylinder 31 and the second semicircular protective cylinder 32 from directly contacting the outer wall of the output pipe 2.

[0040] In a preferred embodiment, such as Figure 3 and Figure 4 As shown, multiple sets of fixing components 5 are equally spaced along the length of the protective component 3 to improve the firmness of the first semicircular protective cylinder 31 and the second semicircular protective cylinder 32 after fixing.

[0041] Preferably, the fixing component 5 includes a fixing screw 51, a fixing block 52 fixedly disposed on the outer wall of the first semi-circular protective cylinder 31, and a fixing seat 53 fixedly disposed on the outer wall of the second semi-circular protective cylinder 32. The fixing seat 53 has a fixing groove 531 facing the fixing block 52. The two sides of the fixing groove 531 are symmetrically connected with a first fixing hole and a second fixing hole. The fixing block 52 has a through hole. When the first semi-circular protective cylinder 31 and the second semi-circular protective cylinder 32 are engaged, the fixing screw 51 passes through the first fixing hole and the through hole in sequence and is inserted into the second fixing hole and threadedly connected to the second fixing hole.

[0042] In this embodiment, when the second semicircular protective cylinder 32 rotates to engage with the first semicircular protective cylinder 31, the fixing block 52 on the first semicircular protective cylinder 31 is inserted into the corresponding fixing groove 531. Then, the fixing screw 51 is rotated so that the fixing screw 51 passes through the first fixing hole and the through hole in sequence and is inserted into the second fixing hole. The inner wall of the second fixing hole is provided with threads, and the fixing screw 51 is threadedly connected to the inner wall of the second fixing hole to fix the fixing block 52. This achieves mutual fixation of the first semicircular protective cylinder 31 and the second semicircular protective cylinder 32, so that the two are engaged to form a cylinder to protect the output pipe 2.

[0043] In a preferred embodiment, such as Figure 2 , Figure 3 and Figure 4 As shown, the installation component 4 includes a positioning post 41, a positioning seat 42, and an elastic fixing member 43. The positioning post 41 is fixedly installed on the tailpipe hanger body 1, and the positioning seat 42 is fixedly installed on the end of the first semi-circular protective cylinder 31 near the tailpipe hanger body 1. The positioning seat 42 has a positioning hole 421 for the positioning post 41 to pass through, and at least one set of elastic fixing members 43 is provided on the top of the positioning seat 42. The elastic fixing members 43 can be inserted into the slots 411 opened on the positioning post 41 for fixation.

[0044] In this embodiment, the positioning seat 42 is a plate-shaped structure with a positioning hole 421 in the middle. When installing the protection, the positioning hole 421 is aligned with the positioning post 41, and the positioning post 41 is inserted into the positioning hole 421. The positioning post 41 plays the role of positioning the first semi-circular protective cylinder 31, so that the protective component 3 is sleeved on the outer wall of the output pipe 2. When the buffer pad 33 on the concave arc surface of the first semi-circular protective cylinder 31 is in contact with the outer wall of the output pipe 2, the elastic fastener 43 is inserted into the slot 411 under its own elasticity and fixed, thereby realizing the installation of the protective component 3. The structure is simple, the operation is convenient, and the installation and fixing of the protective component 3 can be achieved quickly and easily.

[0045] In a preferred embodiment, such as Figure 2 and Figure 4 As shown, the top of the positioning seat 42 is provided with a sliding groove. The elastic fixing member 43 includes a sliding rod fixedly installed in the sliding groove, a spring 431 sleeved on the outside of the sliding rod, and a slider 432 slidably connected to the sliding rod. The slider 432 is fixedly connected to a locking block 433 that matches the locking groove 411. One end of the spring 431 is fixedly connected to the inner wall of the sliding groove, and the other end is fixedly connected to the slider 432. The elastic force of the spring 431 can push the slider 432 to move in the direction close to the positioning post 41, so that the locking block 433 is inserted into the locking groove 411 and fixed.

[0046] In this embodiment, during installation, the slider 432 is manually pushed to compress the spring 431, causing the positioning pin 41 to be inserted into the positioning hole 421. When the locking block 433 is aligned with the slot 411, the slider 432 is released, and the elastic force of the spring 431 pushes the locking block 433 into the slot 411. The elastic force of the spring 431 is large enough to ensure that it can be stably inserted into the slot 411 without falling off when slightly shaken.

[0047] In a preferred embodiment, such as Figure 4 As shown, two sets of elastic fasteners 43 are symmetrically arranged on both sides of the positioning hole 421 at the top of the positioning seat 42, and two sets of slots 411 corresponding to the elastic fasteners 43 are opened on the outer wall of the positioning post 41. Specifically, the symmetrical arrangement of two sets of elastic fasteners 43 improves the firmness of the first semi-circular protective cylinder 31 after installation and prevents the locking blocks 433 from falling off.
