Description

Technical Field

[0001] This invention relates to the field of crude oil pipeline construction technology, specifically to a crude oil pipeline antifreeze pull-out support device with impact function. Background Technology

[0002] Permafrost, also known as frozen soil, tundra, or tundra, refers in physical geography to environments where trees cannot grow due to low temperatures and short growing seasons. In geology, it refers to various rocks and soils containing ice and located below 0°C. It is generally classified into short-term frozen soil, seasonal frozen soil, and perennial frozen soil. Frost pull refers to the phenomenon in seasonally or perennially frozen soil areas where, during the cold season, the soil freezes and expands, causing objects fixed within the permafrost to be lifted up by tangential frost heave forces, losing their anchorage. When the soil thaws in the warmer season, it recedes, and the lifted objects cannot return to their original positions, resulting in frost pull.

[0003] In existing technologies, for frost-resistant pull-out supports of crude oil pipelines in permafrost, transverse support rods are often installed on both sides of the support legs to enhance the vertical fixation of the support legs. During installation, the transverse support rods are retracted inside the support leg to ensure the overall installation of the support leg. Then, a transmission mechanism inside the support leg pushes them outward. However, the transverse support rods often extend beyond their original position due to hard objects in the soil, making normal installation difficult. In severe cases, this necessitates the use of a foundation pit, significantly impacting the construction progress. Therefore, this paper proposes an impact-functional frost-resistant pull-out support device for crude oil pipelines that can be installed in hard soil. Summary of the Invention

[0004] The purpose of this invention is to provide an antifreeze pull-out support device for crude oil pipelines with impact function, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An antifreeze pull-out support device for crude oil pipelines with impact function includes a support plate, a connecting frame mechanism for installing pipelines is installed on the upper part of the support plate, a fixed cylinder is fixedly connected to the lower part of the support plate, and multiple sets of opposing circular through holes are evenly spaced along the length of the fixed cylinder on the cylinder wall. An impact mechanism is installed in two circular through holes in each set, and a connecting rod is provided between the two impact mechanisms. During operation, the impact mechanism is driven to impact the soil by the rotation of the connecting rod.

[0007] The impact mechanism includes: an impact head, a threaded sleeve, a helical base, a sleeve component, and a connecting shaft; the threaded sleeve is slidably mounted on the connecting rod along the axial direction; the impact head is threadedly mounted on the threaded sleeve; the helical base is mounted on the inner wall of the end of the impact head, and the connection between the helical base and the inner wall of the end of the impact head adopts an elastic connection structure; the end face of the helical base has a helical groove; the sleeve component is installed inside the impact head and is coaxial with the impact head; the outer end of the sleeve component is rotatably connected to the side wall of the impact head through a bearing; the helical base is located on one side of the inner side of the sleeve component; a connecting seat is fixedly installed on the other side of the inner side of the sleeve component; and an impact rod is fixedly installed on the side of the connecting seat facing the helical base.

[0008] A limiting post is fixedly installed on the outer wall of the connecting rod. The limiting post is located on the side of the threaded sleeve and is used to limit the movement of the threaded sleeve in the direction of the connecting rod axial direction toward the inside of the fixed cylinder.

[0009] An axial mounting channel is provided inside the connecting rod, and the connecting shaft is slidably mounted in the mounting channel along the axial direction. The other side of the connecting shaft is connected to the connecting seat.

[0010] The anti-freeze pull-out support device also includes a transmission mechanism for driving the rotation of all connecting rods.

[0011] In the above technical solution, the connecting frame mechanism includes a fixed connecting frame and a movable connecting frame. The fixed connecting frame has a U-shaped structure and is fixedly welded to the support plate by the pillars on both sides. The movable connecting frame also has a U-shaped structure, with the openings of the movable connecting frame and the fixed connecting frame facing each other, and the two are detachably connected together by bolts.

[0012] In the above technical solution, two flanges are symmetrically fixed on the wall of the connecting rod. The flanges are arranged along the axial direction of the connecting rod. Correspondingly, a groove slide is provided on the inner wall of the threaded sleeve. The flanges and the groove slide slide together, thereby realizing that the threaded sleeve can be slidably installed on the connecting rod along the axial direction, so that the threaded sleeve and the connecting rod can slide relative to each other along the axial direction but cannot rotate relative to each other.

[0013] In the above technical solution, the outer end of the impact head is conical, which facilitates the impact head impacting the soil outward. Furthermore, a protrusion is provided on the outer end face of the impact head to prevent the impact head from rotating in the soil.

[0014] In the above technical solution, the inner wall of the mounting channel of the connecting rod is provided with a limiting groove arranged along the axial direction, and the side wall of the connecting shaft is provided with a protrusion that matches the limiting groove. The protrusion is slidably connected with the limiting groove, thereby realizing that the connecting shaft can be slidably installed in the mounting channel along the axial direction, so that the connecting shaft and the connecting rod can slide relative to each other along the axial direction but cannot rotate relative to each other.

[0015] In the above technical solution, during operation, the connecting rod rotates, causing the threaded sleeve to rotate synchronously. At this time, because the impact head is in a state of compression with the soil, the impact head is not easy to rotate. Therefore, the rotation of the threaded sleeve will drive the impact head to move outward along the axial direction. At the same time, when the connecting rod rotates, the connecting rod will synchronously drive the connecting shaft to rotate, the connecting shaft will drive the connecting seat to rotate, and the connecting seat will drive the impact rod on it to rotate. Under the cooperation of the impact rod and the spiral groove, the spiral base will drive the impact head to be impacted along the axial direction.

[0016] In the above technical solution, the impact mechanism further includes: a transverse support plate and a transverse impact drive ring. An installation groove is provided on the outer wall of the impact head, and the transverse support plate is installed in the installation groove. The outer wall of the transverse support plate is welded with protrusions distributed in an array. A trigger rod is provided on the inner wall of the transverse support plate, and the trigger rod passes through the impact head radially. The transverse impact drive ring is fixedly welded to the outer wall of the sleeve. An inclined surface is provided on the outer wall of the transverse impact drive ring. When the transverse impact drive ring rotates with the sleeve, the inclined surface on the transverse impact drive ring contacts the trigger rod, thereby squeezing the trigger rod outward, so that the trigger rod drives the transverse support plate to move outward.

[0017] In the above technical solution, the transmission mechanism includes a main transmission gear, which is fixed to one end of a gear connecting rod. The other end of the gear connecting rod is connected to a bevel gear, which meshes with a second bevel gear. The second bevel gear is coaxially and fixedly connected to the main transmission disc. The second bevel gear and the main transmission disc are mounted on a rotating shaft, and both ends of the rotating shaft are rotatably connected to the inner wall of the fixed cylinder. The main transmission gear protrudes from the support plate, and a motor is mounted on the support plate. The motor is connected to the main transmission gear. Each connecting rod is equipped with a slave transmission disc. The main transmission disc and each slave transmission disc are connected by a transmission belt. The rotation of the main transmission disc will synchronously drive all the slave transmission discs to rotate, thereby causing all the connecting rods to rotate. The rotation of the connecting rods drives the impact mechanism to impact the soil.

[0018] In the above technical solution, a tensioning roller is also provided inside the fixed cylinder. A tensioning wheel is rotatably installed in the middle part of the tensioning roller, and the tensioning wheel presses against the transmission belt between each transmission disc to ensure the tension of the transmission belt.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. When the present invention is in operation, the rotation of the connecting rod will drive the threaded sleeve to rotate synchronously. At this time, since the impact head is in a state of compression with the soil, the impact head is not easy to rotate. Therefore, the rotation of the threaded sleeve will drive the impact head to move outward along the axial direction, that is, to extend into the soil. At the same time, when the connecting rod rotates, the connecting rod will drive the connecting shaft to rotate synchronously. The connecting shaft will drive the connecting seat to rotate. The connecting seat will drive the impact rod on it to rotate. Under the cooperation of the impact rod and the spiral groove, the spiral base will drive the impact head to exert an impact force on the impact head along the axial direction, thereby helping the impact head to better extend outward into the hard soil, thereby stabilizing the entire anti-freeze pull-out support device.

[0021] 2. The present invention uses the cooperation of the transverse support plate and the transverse impact ring so that when the impact head moves outward to impact, the transverse support plate will also move outward to support and push, thereby compacting the soil around the impact head radially. In addition, the transverse support plate has an array of protrusions, which is conducive to the connection between the transverse support plate and the surrounding soil, ensuring the stability of the overall support device in the soil.

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] like Figures 1-8 As shown, an antifreeze pull-out support device for crude oil pipelines with impact function includes a support plate 1. A connecting frame mechanism 2 for installing pipelines is installed on the upper part of the support plate 1. The connecting frame mechanism 2 includes a fixed connecting frame 21 and a movable connecting frame 22. The fixed connecting frame 21 has a U-shaped structure and is fixedly welded to the support plate 1 by pillars on both sides. The movable connecting frame 22 also has a U-shaped structure. The opening of the movable connecting frame 22 is opposite to the opening of the fixed connecting frame 21, and the two are detachably connected together by bolts (both sides of the fixed connecting frame 21 and both sides of the movable connecting frame 22 are provided with lugs, and bolts pass through the lugs to connect the fixed connecting frame 21 and the movable connecting frame 22 together).

[0033] A fixed cylinder 6 is fixedly connected to the lower part of the support plate 1. The fixed cylinder 6 is a hollow cylindrical shape. Multiple sets of opposite circular through holes 61 are equally spaced along the length of the fixed cylinder on the cylinder wall of the fixed cylinder 6. That is, the two circular through holes in each set are symmetrically opened on the cylinder wall of the fixed cylinder 6. An impact mechanism 4 is installed in the two circular through holes in each set, and a connecting rod 7 is set between the two impact mechanisms 4. During operation, the rotation of the connecting rod 7 drives the impact mechanism 4 to impact the soil.

[0034] See appendix Figure 3 - Appendix Figure 7The impact mechanism 4 includes an impact head 41, a threaded sleeve 43, a helical base 49, a sleeve 47, and a connecting shaft 45. The threaded sleeve 43 is slidably mounted on the connecting rod 7 along the axial direction. Specifically, two flanges 9 are symmetrically fixed on the wall of the connecting rod 7. The flanges 9 are arranged along the axial direction (i.e., the length direction) of the connecting rod 7. Correspondingly, a groove slide 44 is provided on the inner wall of the threaded sleeve 43. The flanges 9 slide with the groove slide 44, thereby realizing that the threaded sleeve 43 is slidably mounted on the connecting rod 7 along the axial direction, so that the threaded sleeve 43 and the connecting rod 7 can slide relative to each other along the axial direction but cannot rotate relative to each other.

[0035] The impact head 41 is threadedly mounted on the threaded sleeve 43. The threaded sleeve 43 has raised threads on its outer wall, and the impact head 41 has a helical groove on its inner wall, thus enabling the impact head 41 to be threadedly mounted on the threaded sleeve 43. The outer end of the impact head 41 is conical, which facilitates the impact head 41 impacting the soil outwards. The helical base 49 is installed at the center of the inner wall of the end of the impact head 41, and the connection between the helical base 49 and the inner wall of the end of the impact head 41 is an elastic connection structure (which can be made of elastic material or a spring). The end face of the helical base 49 has a helical groove 491. The sleeve 47 is installed inside the impact head 41 and is coaxial with it. The outer end of the sleeve 47 is rotatably connected to the side wall of the impact head 41 via a bearing (this allows the sleeve 47 and the impact head 41 to rotate relative to each other, and the impact head 41 and the sleeve 47 to move synchronously along the axial direction; the bearing is not shown in the figure). The helical base 49 is located on one side inside the sleeve 47 (the helical base...). There is no connection between sleeve 47 and sleeve 49. A connecting seat 46 is fixedly installed on the other side of the sleeve 47 (that is, the connecting seat 46 and sleeve 47 are fixed and move synchronously). An impact rod 48 is fixedly installed on the side wall of the connecting seat 46 facing the spiral base 49. The impact rod 48 is used to cooperate with the spiral groove 491 of the spiral base 49. When the connecting seat 46 rotates, the spiral base 49 can be driven to impact the impact head 41 axially under the cooperation of the impact rod 48 and the spiral groove 491. (Since the connection between the spiral base 49 and the impact head 41 adopts an elastic connection structure, the impact rod 48 on the connecting seat 46 can always contact the end face of the spiral base 49 and the spiral groove 491 on the end face during the rotation of the connecting seat 46. Thus, the impact rod 48 generates an axial impact on the spiral base 49 once every one revolution. This axial impact is transmitted to the impact head 41, that is, an impact is formed on the impact head 41.) This helps the impact head 41 to extend outward into the soil.

[0036] An axial mounting channel 413 is provided inside the connecting rod 7. The connecting shaft 45 is slidably mounted in the mounting channel 413 along the axial direction. Specifically, the inner wall of the mounting channel 413 is provided with a limiting groove 412 arranged along the axial direction. The side wall of the connecting shaft 45 is provided with a protrusion that matches the limiting groove 412. The protrusion is slidably connected to the limiting groove 412, thereby realizing that the connecting shaft 45 is slidably mounted in the mounting channel 413 along the axial direction, so that the connecting shaft 45 and the connecting rod 7 can slide relative to each other along the axial direction but cannot rotate relative to each other. The other side of the connecting shaft 45 is fixedly mounted through the connecting seat 46.

[0037] A limiting post 71 is fixedly installed on the outer wall of the connecting rod 7. The limiting post 71 is located on the side of the threaded sleeve 43 and is used to limit the movement of the threaded sleeve 43 in the direction of the connecting rod 7 toward the inside of the fixed cylinder 6.

[0038] During operation, the rotation of the connecting rod 7 will cause the threaded sleeve 43 to rotate synchronously. At this time, since the impact head 41 is in a state of compression with the soil, the impact head 41 is not easy to rotate. The limiting post 71 limits the movement of the threaded sleeve 43 in the direction of the connecting rod 7 towards the inside of the fixed cylinder 6. Therefore, the rotation of the threaded sleeve 43 will drive the impact head 41 to move outward along the axial direction, that is, to extend into the soil. At the same time, when the connecting rod 7 rotates, the connecting rod 7 will synchronously drive the connecting shaft 45 to rotate. The connecting shaft 45 drives the connecting seat 46 to rotate. The connecting seat 46 drives the impact rod 48 on it to rotate. Under the cooperation of the impact rod 48 and the spiral groove 491, the spiral base 49 is driven to impact the impact head 41 along the axial direction. It should be noted that when the impact head 41 generates an impact, it is first necessary to ensure that the impact head 41 has the ability to move axially so that the impact head 41 can "impact". Because the impact head 41 of the present invention is sleeved on the threaded sleeve 43 and the threaded sleeve 43 is slidably mounted on the connecting rod 7, the impact head 41 has the freedom of axial movement relative to the connecting rod 7, so that the impact head 41 can "impact". Secondly, in order for the impact head 41 to have an impact during its outward extension, it is also necessary to ensure that the impact generating mechanism always follows the impact head 41 in its outward extension. Therefore, the sleeve 47 and the impact head 41 in the present invention are connected by a bearing, and the connecting shaft 45 connected to the connecting seat 46 inside the sleeve 47 is slidably mounted inside the connecting rod 7. Thus, during the outward extension of the impact head 41, the sleeve 47, the connecting seat 46, and the connecting shaft 45 follow the impact head 41, and the connecting shaft 45 can always drive the connecting seat 46 and the impact rod 48 to rotate to generate an impact.

[0039] Furthermore, to effectively prevent the impact head 41 from rotating during operation, see Appendix Figure 7Several protrusions 415 are provided on the outer end face of the impact head 41. The protrusions 415 increase the contact between the impact head 41 and the soil, thereby effectively preventing the impact head 41 from rotating during operation.

[0040] Furthermore, the impact mechanism 4 also includes a transverse support plate 42 and a transverse impact drive ring 411. Through the cooperation of the transverse support plate 42 and the transverse impact drive ring 411, the transverse support plate 42 will also support and move radially outward as the impact head 41 extends outward along the axial direction, thereby compacting the soil around the impact head 41. Specifically, an installation groove is provided on the outer wall of the impact head 41, and a transverse support plate 42 is installed in the installation groove. The outer wall of the transverse support plate 42 is welded with protrusions distributed in an array. A trigger rod 410 is provided on the inner wall of the transverse support plate 42, and the trigger rod 410 penetrates the impact head 41 radially. The transverse impact drive ring 411 is fixedly welded to the outer wall of the sleeve 47. An inclined surface is provided on the outer wall of the transverse impact drive ring 411. When the transverse impact drive ring 411 rotates with the sleeve 47, the inclined surface on the transverse impact drive ring 411 contacts the trigger rod 410, thereby squeezing the trigger rod 410 outward, so that the trigger rod drives the transverse support plate 42 to move outward.

[0041] The anti-freeze pull-out support device of the present invention also includes a transmission mechanism 5 for driving the rotation of all connecting rods 7, see Appendix Figure 8 The transmission mechanism 5 includes a main transmission gear 51, which is fixed to one end of a gear connecting rod 57. The other end of the gear connecting rod 57 is connected to a first bevel gear 55. The first bevel gear 55 meshes with a second bevel gear 58. The second bevel gear 58 is coaxially and fixedly connected to the main transmission disc 59. The second bevel gear 58 and the main transmission disc 59 are mounted on a rotating shaft 56, and both ends of the rotating shaft 56 are rotatably connected to the inner wall of the fixed cylinder 6. Further details can be found in the appendix. Figure 1 The main drive gear 51 protrudes from the support plate 1, and a motor connecting seat 3 is provided on the support plate 1. A motor is installed on the motor connecting seat 3, and the motor is connected to the main drive gear 51 for transmission. The motor drives the main drive gear 51 to rotate, which in turn drives the main drive disc 59 to rotate. Each connecting rod 7 is provided with a slave drive disc 52 (see Appendix). Figure 2 The main drive disc 59 and each slave drive disc 52 are connected by a drive belt 53. The rotation of the main drive disc 59 will synchronously drive all the slave drive discs 52 to rotate, thereby causing all the connecting rods 7 to rotate. The rotation of the connecting rods 7 drives the impact mechanism 4 to impact the soil.

[0042] To elaborate further, see the appendix. Figure 2Inside the fixed cylinder 6, a tension roller 54 is also provided. A tension wheel is rotatably installed in the middle part of the tension roller 54, and the tension wheel presses against the transmission belt 53 between each transmission disc 52 to ensure the tension of the transmission belt 53.

[0043] During operation, the anti-freeze pull-out support device is first placed at the location where it needs to be installed. Then, the fixing cylinder 6 is hammered into the location where it needs to be installed. Next, the motor is installed on the motor connecting seat 3 on the support plate 1. The motor is connected to the main transmission gear 51. Then, the motor is started, and the transmission mechanism 5 drives each connecting rod 7 to rotate. The rotation of the connecting rod 7 drives the impact mechanism 4 to impact the soil, so that each impact head 41 extends outward into the soil, thereby stabilizing the entire anti-freeze pull-out support device.

[0044] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
