Description

Technical Field

[0001] This application belongs to the technical field of riser stability assistance equipment, and particularly relates to a riser anti-settlement assistance device. Background Art

[0002] Risers refer to pipes that are vertically upward or downward, directly connected to equipment such as water pumps and oil pumps, and used to transport media to upper or lower layers. They usually have a relatively large diameter to reduce frictional losses and flow resistance when transporting media. In the industrial field, risers are usually used to transport high-temperature, high-pressure media or for vertical transportation such as cooling water, flue gas, steam and other media. In the construction field, risers are usually used to transport water supply or sewage, etc. Due to the high pressure they bear, they will move downward along the height direction, that is, settle, resulting in the settled riser being unable to be connected to other risers. Currently, in order to avoid riser settlement, several ear blocks are welded around the riser to prevent the riser from settling (increasing the contact area between the riser and the ground). However, when removing the ear blocks, the surface anti-corrosion layer of the riser will be damaged, causing damage to the riser.

[0003] For example, the Chinese invention patent with the publication number "CN202021265951.9" discloses a gas riser anti-settlement and stabilization device, including: a first arc-shaped structure, with a connecting part provided at one end and a locking part one provided at the other end; a second arc-shaped structure, with one end rotatably connected to the connecting part and a locking part two provided at the other end opposite to the locking part one; a locking member, connected to the locking part one or the locking part two, and capable of locking and connecting the locking part one and the locking part two. When the locking part one and the locking part two are locked and connected by the locking member, a clamping cavity that can adapt to clamp the gas riser is defined between the first arc-shaped structure and the second arc-shaped structure. It can fix the gas riser, prevent the upper gas pipe that has not been removed from losing support and shifting downward when the upper gas pipe is truncated and removed, and reduce the potential safety hazards during the transformation or emergency repair of the gas riser.

[0004] In the above solution, one end of the first arc-shaped structure is connected to the second arc-shaped structure by a rivet one, and the other end is connected by the locking member. In this structure, the riser is fixed within the closed loop formed by the first arc-shaped structure and the second arc-shaped structure. At this time, the diameter of the riser can only be slightly larger than the diameter of the closed loop, and risers with a larger diameter cannot be fixed, resulting in a small application range of this structure. Summary of the Invention

[0005] In view of this, it is necessary to provide a solution that can solve the problem that the fixing mechanism can only fix risers with a diameter slightly larger than the diameter of the closed loop, resulting in a small application range of the fixing device.

Fixing plates are provided at both ends of the first arc plate and the second arc plate, fixing holes are provided on the fixing plates, and the locking member is detachably arranged in the fixing holes for connecting the first arc plate and the second arc plate.

[0010] Preferably, a clamping groove is provided on the movable beam, a clamping block is provided on the lower end surface of the fixing plate, and the clamping block is clamped with the clamping groove.

[0015] Preferably, the locking knob includes a knob body and a locking sleeve provided on one side of the knob body.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] To more clearly illustrate the technical solutions of the embodiments of the present application, the drawings required for the embodiments will be briefly introduced below. Obviously, the drawings in the following description are some embodiments of the present application. For those of ordinary skill in the art, other drawings can be obtained based on these drawings without creative efforts.

[0028] Please refer to Figures 1 to 6, a riser anti-settlement auxiliary device, comprising: a support frame 10 and a riser fixing mechanism 20. The support frame 10 includes a plurality of legs 101, a load-bearing frame 102 and a plurality of movable beams 103. The legs 101 are perpendicularly connected to the lower end surface of the load-bearing frame 102, and grooves 1021 are formed on both sides of the load-bearing frame 102. The two ends of the movable beam 103 are placed in the grooves 1021, and the movable beam 103 can move along the grooves 1021. The riser fixing mechanism 20 includes a first arc plate 201, a second arc plate 202 and a locking member 203. The first arc plate 201 and the second arc plate 202 are symmetrically arranged on the movable beam 103 and are slidably connected to the movable beam 103. Fixed plates 30 are provided at both ends of the first arc plate 201 and the second arc plate 202. Fixing holes 301 are formed in the fixed plates 30. The locking member 203 is detachably arranged in the fixing holes 301 for connecting the first arc plate 201 and the second arc plate 202.

[0029] The riser fixing mechanism 20 is arranged on the support frame 10 and is closely attached to the riser. The area is a closed loop or a circular area formed by two semi-circles. At this time, the circular area formed by the two semi-circles is not closed. At this time, the support frame 10 plays a role in fixing and supporting the riser, and the support frame 10 shares a part of the weight of the riser, reducing the pressure of the riser on the ground and avoiding the probability of ground subsidence, thereby reducing the probability of settlement of the riser (reason: the contact area between the support frame 10 and the ground is larger than the contact area between the riser and the ground. According to the relationship between pressure and contact area, the larger the contact area, the smaller the pressure received. At this time, the contact area between the riser and the ground remains unchanged, but a part of the weight of the riser is shared by the support frame 10. At this time, the pressure received by the contact area with the riser will become smaller, thereby reducing the probability of settlement of the riser).

[0030] Meanwhile, the shapes of the first arc-shaped plate 201 and the second arc-shaped plate 202 are: an arc-shaped plate and the fixing plate 30 perpendicular to the tangents at both ends of the arc-shaped plate. The fixing plate 30 is provided with a plurality of fixing holes 301 in the height direction. When setting, the first arc-shaped plate 201 and the second arc-shaped plate 202 are symmetrically arranged, that is, the arc surfaces on the first arc-shaped plate 201 and the second arc-shaped plate 202 are arranged opposite to each other to form the fixing area of the riser. When the riser fixing mechanism 20 is closely arranged against the riser, at this time, the fixing plate 30 will be arranged on the support frame 10 in a relatively parallel position. At this time, the locking member 203 is inserted into the fixing hole 301 to connect the first arc-shaped plate 201 and the second arc-shaped plate 202, so that the horizontal distance between the first arc-shaped plate 201 and the second arc-shaped plate 202 no longer changes, and at this time, the first arc-shaped plate 201 and the second arc-shaped plate 202 are closely attached to the riser, thereby fixing the riser to ensure that the riser will not move downward along the height direction, that is, settlement occurs; and the first arc-shaped plate 201 and the second arc-shaped plate 202 are separately arranged and connected by the locking member 203. At this time, the horizontal distance between the first arc-shaped plate 201 and the second arc-shaped plate 202 can be adjusted to fix risers of different diameters. However, it should be clear here that: the larger the diameter of the riser, the longer the length of the locking member 203. At the same time, the position of the movable beam 103 needs to be adjusted in the groove 1021, and the distance between the movable beams 103 is equal to the diameter of the riser, that is, the first arc-shaped plate 201 and the second arc-shaped plate 202 can be placed on the movable beam 103.

[0031] The technical solution of using a riser anti-settlement auxiliary device in this application can achieve the following beneficial effects:

[0032] By adjusting the horizontal distance between the first arc-shaped plate 201 and the second arc-shaped plate 202, risers of different diameters are fixed, thereby increasing the application range of the riser anti-settlement auxiliary device.

[0033] The riser fixing mechanism 20 is arranged on the support frame 10. Since the support frame 10 bears a part of the weight of the riser, and the contact area between the support frame 10 and the ground is larger than the contact area between the riser and the ground, the area of the ground under pressure is increased, the probability of ground subsidence is reduced, and thus the probability of the riser settlement is reduced.

[0034] In a preferred solution, a clamping groove 1031 is arranged on the movable beam 103, and a clamping block 302 is arranged on the lower end surface of the fixing plate 30. The clamping block 302 is clamped with the clamping groove 1031.

[0035] A clamping groove 1031 is provided along the length direction of the movable beam 103. The clamping block 302 is arranged on the fixed plate 30 and on the side in contact with the movable beam 103. During use, the clamping block 302 is clamped with the clamping groove 1031 to limit the movement tracks of the first arc-shaped plate 201 and the second arc-shaped plate 202, so that the fixed plate 30 can only move along the arrangement direction of the clamping groove 1031, and it is ensured that the fixed plate 30 can only move parallel on the movable beam 103.

[0036] Specifically, gaskets 40 are provided inside the first arc-shaped plate 201 and the second arc-shaped plate 202.

[0037] In order to protect the surface structure of the riser, gaskets 40 are provided inside the first arc-shaped plate 201 and the second arc-shaped plate 202. "Inside the first arc-shaped plate 201 and the second arc-shaped plate 202" means the inner side of the arc surface formed by the first arc-shaped plate 201 and the second arc-shaped plate 202, that is, the inner side of the curved surface, and this inner side is the side in contact with the riser. During use, the surface of the riser is protected by the gaskets 40 to avoid damage to the anti-corrosion layer or anti-rust layer on the surface of the riser due to friction or force, better protect the surface of the riser, and avoid the situation that the riser fails to meet the use requirements due to damage to the anti-corrosion layer or anti-rust layer, and can better protect the riser.

[0038] Furthermore, a number of limiting grooves 1022 are provided in the groove 1021. Fixed rods 1032 are arranged at both ends of the movable beam 103. The fixed rods 1032 extend into the groove 1021 and are clamped with the limiting grooves 1022.

[0039] To prevent the movable beam 103 from sliding horizontally due to excessive force, a limiting groove 1022 is provided in the groove 1021. The limiting groove 1022 fixes the horizontal position of the movable beam 103. Most importantly, when the fixing rod 1032 is a round bar-shaped fixing rod 1032, the fixing rod 1032 is in line contact with the groove 1021. In this case, under force, the fixing rod 1032 will roll. At this time, the fixing rod 1032 is placed in the limiting groove 1022, increasing the contact area between the fixing rod 1032 and the limiting groove 1022, and enabling better fixing of the position of the fixing rod 1032. At the same time, to prevent the upper end surface of the support frame 10 from bending due to excessive force caused by the groove 1021 being too large, fixing rods 1032 can be provided at both ends of the movable beam 103. The fixing rods 1032 extend into the groove 1021 and are snap-connected to the limiting groove 1022. At this time, the size of the fixing rod 1032 is smaller than the size of the movable beam 103, thereby avoiding the need to open a groove 1021 with a larger aperture.

[0040] In a preferred embodiment, a limiting block 1033 is provided at the end of the fixing rod 1032.

[0041] If one end of the fixing rod 1032 completely extends into the limiting groove 1022 and protrudes from the limiting groove 1022, at this time, the contact distance between the other end of the fixing rod 1032 and the limiting groove 1022 will be too short, or even unable to contact the limiting groove 1022. At this time, the movable beam 103 will fall off the bearing frame 102. To avoid this situation, a limiting block 1033 is provided at the end of the fixing rod 1032, so that both ends of the fixing rod 1032 can contact the limiting groove 1022, and the contact distances are equal. Moreover, the size of the limiting block 1033 is larger than the size of the groove 1021.

[0042] In a specific embodiment, the locking member 203 includes a connecting rod 2031 and a locking knob 2032. One end of the connecting rod 2031 passes through the fixing hole 301, and the other end is rotationally connected to the locking knob 2032 by a thread, and the locking knob 2032 can slide on the connecting rod 2031.

[0043] During installation, one end of the connecting rod 2031 is a threaded section and the other end is a fixed end. During use, the threaded section passes through the fixing hole 301, and the fixed end contacts the fixing plate 30. Then, the threaded section passing through the fixing hole 301 is threadedly engaged with the locking knob 2032 to reduce the horizontal distance between the first arc-shaped plate 201 and the second arc-shaped plate 202 until the first arc-shaped plate 201 and the second arc-shaped plate 202 are in close contact with the vertical pipe.

[0044] Specifically, the locking knob 2032 includes a knob body 2033 and a locking sleeve 2034 provided on one side of the knob body 2033. The locking sleeve 2034 is provided with a threaded hole that can be adapted to the thread, and the knob body 2033 is provided with an avoidance hole 2035 for avoiding the connecting rod 2031. The threaded hole communicates with the avoidance hole 2035, and the connecting rod 2031 is screwed into the avoidance hole 2035.

[0045] When the locking knob 2032 is connected to the connecting rod 2031, the threaded end on the connecting rod 2031 first penetrates into the locking sleeve 2034. Then, the threaded hole in the locking sleeve 2034 is threadedly engaged with the threaded end. An avoidance hole 2035 is provided on the knob body 2033. The avoidance hole 2035 is a cavity. The function of the avoidance hole 2035 is to accommodate the connecting rod 2031 that penetrates into the threaded hole. The reason is that after the threaded end on the connecting rod 2031 penetrates into the threaded hole, the connecting rod 2031 will continue to move towards one side of the knob body 2033. At this time, without the avoidance hole 2035, the connecting rod 2031 cannot fixedly connect the first arc-shaped plate 201 and the second arc-shaped plate 202, and at this time, the vertical pipe cannot be fixed.

[0046] In another embodiment, the locking member 203 further includes a bolt and a nut that matches the bolt. One end of the bolt passes through the fixing hole 301, and the nut is rotatably connected to the other end of the bolt.

[0047] To simplify the installation process, the locking member 203 can be set as a bolt and a nut. The bolt passes through the fixing hole 301, and the nut is screwed onto the bolt to achieve the purpose of connecting the first arc-shaped plate 201 and the second arc-shaped plate 202. Moreover, the bolt and the nut are more convenient for installation and disassembly, and the manufacturing and acquisition of the bolt and the nut are easier and the cost is lower.

[0048] The above-disclosed is only a preferred embodiment of the present application. Of course, it cannot be used to limit the scope of rights of the present application. Those of ordinary skill in the art can understand all or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present application still fall within the scope covered by the present application.
