Description

Technical Field

[0001] This utility model relates to pipeline assembly in the chemical industry, specifically to a three-dimensional adjustable vertical support device that uses an elbow flange as a fulcrum. Background Technology

[0002] In the pipeline laying process in the chemical industry, elbows are important pipe fittings connecting pipelines. Elbow support structures are structural forms used to support the weight of the elbow, as well as the weight of the pipes, valves, and the internal media connected to the elbow. The elbow support structure has a significant impact on the service life of the elbow. Conventional elbow supports involve welding trunnions to the bottom of the vertical elbow for support, such as... Figure 1 As shown, the trunnion 3 is supported on the ground or platform. This conventional approach has several disadvantages:

[0003] (1) When the trunnion and elbow are welded together, under the action of voltage and current, the welding position of the base material on the elbow surface fuses with the trunnion at high temperature. The grains of the base material at the fusion position will grow, the properties of the base material will change, the original strength, hardness and toughness of the base material will deteriorate, the welding position becomes a weak point, shortens the service life of the elbow base material, and makes the welding position prone to leakage.

[0004] (2) When the trunnion and elbow are welded, the weld fusion point will shrink under high temperature, which will cause welding stress, reduce the strength of the elbow base material, shorten the service life of the elbow base material, and make the weld position prone to leakage.

[0005] (3) After the trunnion and the elbow are welded, the trunnion has to bear the weight of the elbow, the pipe connected to the elbow, the valve, and the medium inside the elbow. Especially for large-diameter elbows, the weight they bear will be even greater. Therefore, the welding position will become a point of stress concentration, which is prone to leakage.

[0006] (4) During the flow of the internal fluid medium of the elbow, the change of pipeline pressure will bring impact to the elbow, causing the elbow to vibrate or shake. The welding position between the trunnion and the elbow will be torn due to long-term vibration or shaking, causing leakage.

[0007] In the chemical industry, the flowing medium inside pipes and elbows is often corrosive, which accelerates the penetration corrosion at the welded joint between the elbow and the trunnion, causing leaks. Utility Model Content

[0008] This utility model provides a three-dimensional adjustable vertical support device that uses an elbow flange as a fulcrum. The elbow flange is equipped with a ring of flange bolts. The three-dimensional adjustable vertical support device consists of a support frame and a three-dimensional adjustable vertical support.

[0009] The support frame consists of a horizontal rectangular frame and legs installed at the bottom of the horizontal rectangular frame. Three-dimensional adjustable vertical supports are installed on both sides inside the horizontal rectangular frame. The bent section of the elbow flange passes through the horizontal rectangular frame and is supported at the bottom of the flange by the three-dimensional adjustable vertical supports to fix the elbow flange to the support frame.

[0010] The interior of the horizontal rectangular frame is fixed with adapter plates on both sides for installing three-dimensional adjustable vertical supports. The three-dimensional adjustable vertical supports consist of an X-axis adjustable base plate, a Y-axis adjustable seat, and a Z-axis adjusting screw for connecting the X-axis adjustable base plate and the Y-axis adjustable seat. The X-axis and Y-axis are two directions in the horizontal dimension, and the Z-axis is the vertical direction.

[0011] The X-axis adjustment base plate is provided with an X-direction oblong hole for bolt connection with the adapter plate and to achieve X-direction position adjustment.

[0012] The Y-axis adjusting seat is a hollow seat consisting of a support plate, a top plate, and multiple vertical plates installed between the support plate and the top plate. One side of the top plate is provided with a Y-direction waist-shaped hole for inserting flange bolts and inserting them into the bottom gap of the flange, so as to realize the Y-direction position is adjustable.

[0013] The Z-axis adjusting screw consists of a adjusting screw, a lifting adjusting nut, a fixing nut, and an anti-loosening nut. The bottom of the adjusting screw is fixedly connected to the X-axis adjusting base plate, and the top of the adjusting screw passes through the support plate. The fixing nut, the lifting adjusting nut, and the anti-loosening nut are threaded on the adjusting screw from top to bottom. The fixing nut and the lifting adjusting nut are located on the upper and lower sides of the support plate, respectively. By rotating the lifting adjusting nut, the Y-axis adjusting seat is driven to move up and down along the Z direction.

[0014] Furthermore, the horizontal rectangular frame consists of two I-beams and two channel beams, with the two ends of the channel beams fixed to the top of the two I-beams by bolts.

[0015] I-shaped steel legs are welded and fixed at both ends of the bottom of the I-shaped steel beam. A base plate is welded to the bottom of the I-shaped steel legs. The base plate is fixedly connected to the ground or workbench by expansion bolts or welding.

[0016] Furthermore, the transition plate is an I-shaped steel bracket welded to the inner side of the I-shaped steel beam flange, and a reinforcing elbow plate is provided between the I-shaped steel bracket and the I-shaped steel beam flange.

[0017] Both sides of the X-axis adjusting base plate are provided with X-direction waist-shaped holes and are connected to the top horizontal wing plate of the I-shaped steel bracket by the first bolt.

[0018] Furthermore, the flange bolts are clearance-fitted with the Y-direction oblong hole.

[0019] Furthermore, upright plates are installed between the two sides of the support plate and the top plate, and a waist-shaped hole in the Y direction is located between the two upright plates;

[0020] The upper and lower ends of the upright plate are welded and fixed to the support plate and the top plate.

[0021] The technical advantages of this utility model are as follows:

[0022] 1) Avoiding welding damage: Unlike traditional elbow support structures (where trunnions are welded below the elbow), this device secures the elbow by supporting the bottom of the elbow flange, avoiding welding on the elbow body. This eliminates the high temperatures and currents caused by welding, as well as the resulting grain growth, performance changes, and decreased strength and toughness of the base material. This prevents the welded area from becoming a weak point or stress concentration point, extending the elbow's service life and reducing the risk of leakage.

[0023] 2) Elimination of vibration and corrosion effects: Support points in traditional welding methods are prone to tearing due to the impact, vibration, and shaking of the fluid medium inside the pipeline, or accelerated penetration corrosion due to corrosive media, leading to leaks. This device effectively avoids these problems by supporting the flange.

[0024] 3) Achieves three-dimensional adjustable position of the elbow flange: This support device has a three-dimensional adjustable function, enabling precise adjustment of the elbow flange position.

[0025] Adjustable in the X direction: The X-axis adjustment base plate has an X-direction oblong hole that, when fitted with a bolt, allows for position adjustment in the X direction.

[0026] Y-axis adjustable: The Y-axis adjusting seat has a Y-axis oblong hole that can be inserted into the flange bolt to adjust the position in the Y direction.

[0027] Z-axis adjustable: The Z-axis adjusting screw can drive the Y-axis adjusting seat to rise or fall in the Z-axis (vertical direction) by rotating the lifting adjusting nut, thus achieving height adjustment. Attached Figure Description

However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0036] To fully understand this utility model, detailed steps and structures will be presented in the following description to illustrate the technical solution of this utility model. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.

[0037] Reference Figure 2-6 As shown, this utility model provides a three-dimensional adjustable vertical support device that uses an elbow flange 1 as a fulcrum. The elbow flange 1 is equipped with a ring of flange bolts 2. The three-dimensional adjustable vertical support device of this utility model is mainly composed of a support frame 100 and a three-dimensional adjustable vertical support 200. The structure of this utility model will be further described below.

[0038] Support frame 100

[0039] like Figure 2 As shown, the support frame 100 consists of a horizontal rectangular frame 110 and legs 120 installed at the bottom of the horizontal rectangular frame 110. Three-dimensional adjustable vertical supports 200 are installed on both sides inside the horizontal rectangular frame 110. The bent section of the elbow flange 1 passes through the horizontal rectangular frame 110 and is supported by the three-dimensional adjustable vertical supports 200 to fix the elbow flange 1 to the support frame 100.

[0040] In an optional embodiment, the horizontal rectangular frame 110 consists of two I-beams 111 and two channel beams 112, with the two ends of the channel beams 112 fixed to the top of the two I-beams 111 by bolts 113.

[0041] I-shaped steel beam 111 has I-shaped steel legs 120 welded and fixed at both ends of its bottom. The bottom of the I-shaped steel legs 120 has a base plate 121 welded to its bottom. The base plate 121 is fixedly connected to the ground or workbench by expansion bolts 122 or by welding.

[0042] 200-dimensional adjustable vertical support

[0043] like Figure 3-6 As shown, the horizontal rectangular frame 110 has adapter plates 130 fixed on both sides inside for installing a three-dimensional adjustable vertical support 200. The three-dimensional adjustable vertical support 200 consists of an X-axis adjustable base plate 210, a Y-axis adjustable seat 220, and a Z-axis adjusting screw 230 for connecting the X-axis adjustable base plate 210 and the Y-axis adjustable seat 220. The X-axis and Y-axis are two directions in the horizontal dimension, and the Z-axis is the vertical direction.

[0044] The X-axis adjusting base plate 210 is provided with an X-direction waist-shaped hole 211, which is used to bolt to the adapter plate 130 and realize the X-direction position adjustment of the three-dimensional adjustable vertical support 200.

[0045] The Y-axis adjusting seat 220 is a hollow seat composed of a support plate 221, a top plate 222, and multiple vertical plates 223 installed between the support plate 221 and the top plate 222. The top plate 222 has a Y-direction waist-shaped hole 224 on one side, which is used to insert the flange bolt 2 and insert it into the bottom gap of the flange, so as to realize the Y-direction position adjustment of the three-dimensional adjustable vertical support 200.

[0046] The Z-axis adjusting screw 230 consists of a screw 231, a lifting adjusting nut 232, a fixing nut 233, and an anti-loosening nut 234. The bottom of the screw 231 is fixedly connected to the X-axis adjusting base plate 210, and the top of the screw 231 passes through the support plate 221. The fixing nut 233, the lifting adjusting nut 232, and the anti-loosening nut 234 are threaded onto the screw 231 from top to bottom. The fixing nut 233 and the lifting adjusting nut 232 are located on the upper and lower sides of the support plate 221, respectively. Rotating the lifting adjusting nut 232 causes the Y-axis adjusting seat 220 to move up and down in the Z direction. The fixing nut 233, in conjunction with the lifting adjusting nut 232, locks the Z-axis position, preventing height deviation due to vibration during use. The anti-loosening nut 234 further eliminates the risk of the lifting adjusting nut 232 falling off, improving the safety and stability of the device.

[0047] In an optional embodiment, the adapter plate 130 is an I-shaped steel bracket welded to the inner side of the flange of the I-shaped steel beam 111, and a reinforcing elbow plate is provided between the I-shaped steel bracket and the flange of the I-shaped steel beam 111. The X-axis adjusting base plate 210 has X-direction oblong holes 211 on both sides (e.g., ...). Figure 5 It is connected to the top horizontal flange of the I-shaped steel bracket by the first bolt 132.

[0048] In an optional embodiment, the flange bolt 2 is clearance-fitted with the Y-direction oblong hole 224, facilitating the adjustment of the flange bolt 2's position, such as... Figure 6 As shown.

[0049] In an optional embodiment, a vertical plate 223 is installed between the two sides of the support plate 221 and the top plate 222, and a Y-direction oblong hole 224 is located between the two vertical plates 223; the upper and lower ends of the vertical plate 223 are welded and fixed to the support plate 221 and the top plate 222. The hollow seat structure composed of the support plate 221, the top plate 222 and the vertical plate 223 ensures the support strength of the Y-axis adjusting seat 220 while reducing the weight of the components. The vertical plate 223 provides protection on both sides of the Y-direction oblong hole 224, preventing the flange bolts from shifting and dislodging from the oblong hole during adjustment, thus improving structural stability.

[0050] The operation steps of this utility model are as follows:

[0051] Step 1: Adjust the distance and position of the three-dimensional adjustable vertical support 200 in the X direction by adjusting the X-axis waist-shaped hole 211 on the base plate 210 and the first bolt 132 fixed on the adapter plate 130, so that the three-dimensional adjustable vertical support 200 is aligned with the optimal support point position of the elbow flange.

[0052] Step 2: After confirming the optimal fulcrum position through Step 1, insert the top plate 222 with the Y-direction oblong hole 224 under the flange. A bolt and gasket on the flange are stuck in the Y-direction oblong hole 224, and the optimal fulcrum position can be adjusted in the Y direction.

[0053] Step 3: After confirming that Step 1 and Step 2 have been completed, tighten the first bolt 132 on the X-direction oblong hole 211 and the adapter plate 130.

[0054] Step 4: Following the same steps, symmetrically operate the other three-dimensional adjustable vertical support below the elbow flange, adjust it into place, and tighten the first bolt 132;

[0055] Step 5: Loosen the retaining nut 233 on one of the set screws and rotate the retaining nut 233 upwards to a certain distance;

[0056] Step 6: Simultaneously loosen the anti-loosening nut 234 on the same set screw, and rotate it down to a certain distance;

[0057] Step 7: Following the same steps, symmetrically operate the fixing nut 233 and the anti-loosening nut 234 on the other set screw below the elbow flange;

[0058] Step 8: Simultaneously operate the lifting and adjusting nuts 232 on the two set screws symmetrically to lift the flange and elbow at the same time;

[0059] Step 9: Use a level to measure the levelness of the flange being lifted, use a tape measure to measure the vertical height being lifted, and compare it with the original vertical height data. Stop lifting when the height data meets the design requirements.

[0060] Step 10: After confirming that step 9 has been completed correctly, tighten the fixing nut 233 and the anti-loosening nut 234.

[0061] After completing the above steps, the elbow flange is assembled. Assembly is a common technique used by those skilled in the art and will not be described in detail here.
