Description

Technical Field

[0001] This invention relates to the field of large-diameter storage tank installation, and in particular to a device and method for synchronously installing a large-diameter storage tank and an isolation liner. Background Technology

[0002] Currently, large-diameter vertical storage tanks are generally constructed on-site using the inverted assembly method. In this process, the topmost cylindrical section is installed first, and then the assembled tank parts are lifted layer by layer upwards using hydraulic or mechanical lifting devices located inside the tank body. New cylindrical sections are then assembled below in sequence until the entire tank structure is completed. After the entire tank body is installed and passes inspection, an isolation lining is manually laid or installed on the inner wall of the tank to achieve corrosion prevention, seepage prevention, or media isolation functions.

[0003] However, because the lifting mechanism required for the inverted installation method must be located inside the tank and close to the tank wall, it occupies a significant amount of working space inside the tank. This means that the lining cannot be installed simultaneously with the tank body and must be carried out as a separate subsequent process. Due to the dense equipment inside the tank, narrow passages, and safety regulations, the lining construction can only be carried out after the lifting device has been removed, the tank body has been completely sealed, and the interior has been cleaned. This not only significantly extends the overall construction period but also increases management and coordination costs due to the second entry into the site.

[0004] Furthermore, the phased construction of the tank body and the inner lining makes it difficult for the inner lining to fit tightly against the tank wall under ideal working conditions, which can easily lead to defects such as poor overlap, stress concentration or local voids, thereby affecting the sealing performance and long-term service reliability of the storage tank. Therefore, a device and method for synchronous installation of large-diameter storage tanks and isolation inner linings are proposed to solve the above problems. Summary of the Invention

[0005] The main objective of this invention is to provide a device and method for the synchronous installation of a large-diameter storage tank and an isolation liner, thereby solving the problem in the prior art where the lifting device is located inside the tank, which prevents the tank and the isolation liner from being constructed synchronously, resulting in extended construction period, increased construction costs, and difficulty in ensuring the quality of liner bonding.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a device and method for synchronously installing a large-diameter storage tank and an isolation liner, comprising a tank body and a lifting device arranged in a ring around the bottom of the tank body. The tank body is a tank body assembled by overlapping multiple ring cylindrical sections. Each cylindrical section is assembled by overlapping multiple arc-shaped pieces. A lifting component is detachably fixed at the bottom of the vertical overlap of the cylindrical sections for connecting the lifting device. The number of lifting devices is even, and they are used to alternately lift the installed cylindrical sections and newly added cylindrical sections.

[0007] In the preferred embodiment, the lifting device includes a vertical frame with multiple crossbeams fixed thereon. Support legs are fixed at the bottom of the vertical frame and are fixed to the ground. A diagonal brace is fixed at the top of the vertical frame on the side away from the tank body, and the other end of the diagonal brace is fixedly supported on the ground. A lifting mechanism, which is a hand-operated hoist, is hoisted at the top of the vertical frame.

[0008] In the preferred embodiment, the lifting component includes a bent plate, one plate surface having a fastening hole for connection with the vertical overlap, and the other plate surface having a connection port for easy hooking of the lifting mechanism.

[0009] In the preferred embodiment, a fan-shaped gap area is formed between two adjacent lifting devices and the outer wall of the cylinder section, and the arc-shaped plate of the next ring cylinder section passes through the wide opening side of the fan-shaped gap.

[0010] In a preferred embodiment, an installation mechanism is also included, which is used to install the arc-shaped plate of the lower cylinder section. The mounting mechanism includes a radial moving assembly for pushing the arc-shaped piece to move radially, a lateral moving assembly disposed on the radial moving assembly for adjusting the lateral position of the arc-shaped piece, positioning members disposed on both sides of the radial moving assembly for forming abutment positioning with the lifting devices on both sides, an angle adjusting assembly disposed on the lateral moving assembly for adjusting the mounting angle of the arc-shaped piece, and a limiting assembly and a height adjusting assembly disposed on the angle adjusting assembly. The limiting assembly is used to vertically restrict the arc-shaped piece within it, and the height adjusting assembly is used to adjust the height of the arc-shaped piece. The limiting component consists of four columns arranged in a trapezoidal shape, with arc-shaped limiting grooves between them for placing the arc-shaped piece.

[0011] In the preferred embodiment, the radial movement assembly includes a base frame, a rail is provided on the top of the base frame, a radial movement seat is provided on the top of the base frame that slides with the rail, a mounting seat is provided on the bottom side of the base frame away from the cylinder section, a radial telescopic cylinder is mounted on the mounting seat, and the telescopic end of the radial telescopic cylinder is connected to the radial movement seat. The lateral movement assembly includes a lateral slide groove disposed on the top of the radial movement seat, a lateral movement seat slidably disposed in the lateral slide groove, a lateral telescopic cylinder disposed on the side of the radial movement seat, a lateral movement connector disposed on the side of the lateral movement seat, and the telescopic end of the lateral telescopic cylinder being connected to the lateral movement connector. The angle adjustment assembly includes a slewing bearing located at the center of the top of the transverse support, a rotary table mounted on the rotating shaft of the slewing bearing, slewing grooves at both ends of the top of the transverse support, an arc support block that slides with the slewing groove at the bottom of the rotary table, a fixed gear ring on the outside of the fixed support shaft of the slewing bearing, and a rotation drive device on the side of the rotary table, with a drive gear meshing with the fixed gear ring on its output shaft. The height adjustment assembly includes a receiving groove on the top of the rotary table and a lifting platform movably disposed in the receiving groove, the top surface of which is flush with the top surface of the rotary table. The lifting platform is also provided with a groove for avoiding the rotary drive device. The top of the rotary table is provided with multiple lifting telescopic cylinders, and the top of the lifting platform is provided with a lifting connector that connects to the telescopic end of the lifting telescopic cylinder.

[0012] In the preferred embodiment, each of the two adjacent lifting devices is provided with a row of vertical lowering guide components, which are fixed to the top of the vertical frame and the crossbeam respectively, for continuous radial and circumferential positioning guidance of the arc-shaped piece; The lowering guide component includes a guide seat body. A guide groove is provided on one side edge of the guide seat body near the cylindrical section. The arc-shaped piece achieves its positioning effect by passing through the left and right guide grooves. An alignment slope is provided at the top of the guide groove of the uppermost lowering guide component.

[0013] In the preferred embodiment, two guide grooves are provided on the side edge of the guide seat near the cylindrical section, corresponding to the arc-shaped pieces on both sides respectively.

[0014] The method includes: S1. Complete the installation of the top first ring section on the foundation concrete and place the flexible liner inside it; S2. Install the tank top on the cylindrical section of the first ring, and simultaneously suspend the top of the flexible liner on it; S3. Install lifting devices and installation mechanisms around the first ring section, and install temporary lifting components at the bottom of the vertical overlap of the section. Connect half of the equidistant lifting devices to the lifting components, and then lift the first ring section using the lifting devices. The lifting height needs to meet the installation requirements of the second ring section. S4. Assemble the second ring section below the first ring section using the installation mechanism. During the assembly process, fix the fixed plates distributed in a ring on the outside of the flexible liner to the corresponding upper and lower overlapping parts of the ring section, and at the same time complete the installation of the ring lifting component. S5. Connect the other half of the lifting devices to the lifting components of the second ring section and tighten them. Then disconnect the lifting devices of the first layer and remove the lifting components on them. Then lift the second ring section to the corresponding height. S6. Repeat steps S4-S5, installing layer by layer until the height of the main body of the storage tank reaches the design requirements. After removing the installation mechanism and lifting device, anchor the main body of the storage tank to the foundation concrete.

[0015] In the preferred embodiment, the specific installation method of step S4 is as follows: the arc-shaped piece is hoisted through the fan-shaped gap area between the lifting device and the cylinder section using hoisting equipment, and placed on the lifting device. The arc-shaped piece is then adjusted to the installation position by the lifting device so that its top overlaps with the upper cylinder section and is then fixed. This step is repeated to install the remaining arc-shaped pieces one by one, and to form a connection structure between the arc-shaped pieces in the same layer with one side overlapping and the other side overlapping, until the second ring cylinder section is installed. When installing the last arc-shaped piece of the cylinder section, since its opening is smaller than the arc-shaped piece and both ends need to form an inner and outer overlap, the installation process is as follows: rotate it to the installation angle and push it radially to the installation position. Then move the arc-shaped piece towards the outer overlap side so that the inner overlap side can pass through the opening. Then push it radially to the installation position, and then move it laterally in the opposite direction to put the overlaps on both sides into place. Finally, adjust its height so that the top overlap is aligned with the upper cylinder section.

[0016] This invention provides a device and method for the simultaneous installation of a large-diameter storage tank and its insulating liner. By placing the lifting device outside the tank body, the working space inside the tank is effectively freed up, allowing the insulating liner to be installed simultaneously during the tank assembly process. This avoids the process interruption caused by the lifting mechanism occupying the tank's internal area in traditional processes. This not only significantly shortens the overall construction cycle and reduces the management and coordination costs of secondary site visits, but also allows the liner to be precisely laid and fitted in an open, safe, and visible working environment. This greatly improves the overlap sealing and structural consistency, effectively avoiding quality defects such as wrinkles, voids, or stress concentration, thereby improving the construction efficiency, installation accuracy, and long-term service reliability of the large-diameter storage tank. At the same time, the even-numbered arrangement of the lifting devices, combined with the fan-shaped clearance area, lowering guide components, and installation mechanism, further ensures the stability and operability of the liner-lined sections during alternating lifting and docking processes.

Detailed Implementation

[0019] Example 1 like Figure 1-17 As shown, a device for synchronously installing a large-diameter storage tank and an insulating liner includes a storage tank body 1 and a lifting device 2 arranged in a ring around the bottom of the storage tank body 1. The storage tank body 1 includes a tank body 10 and a flexible liner 11 disposed on the inner wall of the tank body 10. The tank body 10 is assembled from multiple ring sections 101 and a tank top 102. Each section 101 is assembled from multiple arc-shaped pieces 1010. In this embodiment, the tank body 10 is assembled by bolts. There are staggered overlapping parts between each arc-shaped piece 1010 and between each section 101, and corresponding fixing holes are provided on the overlapping parts. Fixing is achieved by installing bolts in the fixing holes. The specific number of arc-shaped pieces 1010 and sections 101 depends on the size of the storage tank body 1.

[0020] The lifting device 2 completes the synchronous installation of the tank body 10 and its internal flexible liner 11 by means of the "inverted installation method". By setting it around the bottom of the tank body 10, specifically on the outside of the tank body 10, it can create conditions for the synchronous installation of the flexible liner 11 and the storage tank body 1.

[0021] In the preferred embodiment, the number of lifting devices 2 is even, which are used to alternately lift the installed cylinder section 101 and the newly added cylinder section 101 to realize the continuous assembly operation of the cylinder section 101.

[0022] In the preferred embodiment, the lifting device 2 includes a vertical frame 202, which is an inverted V-shaped structure with a flat top. Multiple crossbeams 203 are fixedly installed therein. Support legs 201 are fixedly installed at the bottom of the vertical frame 202 and are fixed to the ground. A diagonal brace 205 is fixedly installed on the side of the top of the vertical frame 202 away from the tank 10. The other end of the diagonal brace 205 is fixedly supported on the ground, thereby stably fixing the lifting device 2 to the ground. At the same time, a lifting mechanism 204 is hoisted at the top of the vertical frame 202 to lift the installed cylinder section 101 to facilitate the installation of the next cylinder section 101. In this embodiment, the lifting mechanism 204 is a hand-operated hoist.

[0023] In this embodiment, the frame structure of the lifting device 2 is fixed by welding. In addition, the height of the vertical frame 202 and the lifting capacity of the lifting mechanism 204 are sufficient to lift the installed cylinder section 101 to a height that meets the requirements for the installation of the next cylinder section 101.

[0024] It should be noted that each lifting device 2 is respectively installed at the vertical overlap of the cylindrical section 101.

[0025] A lifting member 3 is detachably fixed at the bottom of the vertical overlapping part of the cylindrical section 101, so that the lifting mechanism 204 can connect to the lifting member 3 and lift the installed cylindrical section 101.

[0026] The lifting component 3 includes a bent plate 3. In this embodiment, the bent plate 3 is L-shaped. Its horizontal plate is provided with fastening holes 301 corresponding to the vertical overlapping part, so that it can be directly fixed to the bolt of the vertical overlapping part and temporarily fastened by the nut. After use, it can be removed by unscrewing the nut and finally tightened. The vertical plate is provided with a connection port 302 for easy hooking of the lifting mechanism 204.

[0027] Since the lifting device 2 is located on the outside of the cylindrical section 101, and each arc-shaped piece 1010 needs to form a vertical overlap between adjacent cylindrical sections, and the position of the lifting device 2 corresponds to the overlap, when the installed cylindrical section 101 is lifted, the arc-shaped piece 1010 of the lower cylindrical section 101 needs to be obliquely inserted into it from the two lifting devices 2.

[0028] Or such as Figure 4 As shown, by utilizing the fan-shaped gap area enclosed by the two adjacent lifting devices 2 and the outer wall of the cylinder section 101, starting from a certain radial distance from the outer wall of the cylinder section 101, i.e. passing through the wide side of the fan-shaped gap, and passing through the fan-shaped gap area between the lifting device 2 and the upper cylinder section 101 in the vertical direction, interference during the lifting process of the two lifting mechanisms 204 is avoided.

[0029] In this embodiment, since the inner wall of the cylindrical section 101 needs to be installed with a flexible inner liner 11 simultaneously, the horizontal oblique insertion method would occupy too much space inside the cylindrical section 101, which would easily cause unnecessary scratching with the flexible inner liner 11. Therefore, it is preferable to start from a certain radial distance from the outer wall of the cylindrical section 101 and insert it vertically into the installation gap between the lifting device 2 and the upper cylindrical section 101.

[0030] To achieve precise installation of the arc-shaped piece 1010 in a confined space during the above process, this embodiment also includes an installation mechanism 4 disposed between adjacent lifting devices 2.

[0031] The mounting mechanism 4 includes a radial moving component 40 for pushing the arc-shaped piece 1010 to move radially, a lateral moving component 42 disposed on the radial moving component 40 for adjusting the lateral position of the arc-shaped piece 1010, positioning members 41 disposed on both sides of the radial moving component 40 for forming an abutment relationship with the lifting devices 2 on both sides, thereby positioning the mounting mechanism 4 in place, an angle adjusting component 43 disposed on the lateral moving component 42 for adjusting the mounting angle of the arc-shaped piece 1010, and a limiting component 44 and a height adjusting component 45 disposed on the angle adjusting component 43. The limiting component 44 is used to vertically restrict the arc-shaped piece 1010 within it, and the height adjusting component 45 is used to adjust the height of the arc-shaped piece 1010, thereby completing its connection with the upper cylindrical section 101.

[0032] With this design, the arc-shaped piece 1010 can be lowered between the limiting components 44 and moved to the installation position via the radial moving component 40. During this process, the angle of the arc-shaped piece 1010 can be adjusted by the angle adjusting component 43 to meet the installation requirements. If necessary, its lateral position can be adjusted by the lateral moving component 42. After it is in place, the installation height can be adjusted by the height adjusting component 45 so that its sides and top meet the overlapping requirements. Finally, it can be fixed with bolts.

[0033] In a preferred embodiment, the radial movement assembly 40 includes a base frame 401. Two parallel rails 402 are provided on the top of the base frame 401. The ends of the base frame 401 and the rails 402 extend into the cylindrical section 101. A radial movement seat 405 is provided on the top of the base frame 401 and slides with the rails 402. A radial groove adapted to the rails 402 is provided at the bottom of the radial movement seat 405. A mounting seat 403 is provided on the bottom side of the base frame 401 away from the cylindrical section 101. A radial telescopic cylinder 404 is mounted on the mounting seat 403. In this embodiment, there are two radial telescopic cylinders 404. The telescopic ends of the radial telescopic cylinders 404 are connected to the radial movement seat 405, so that the radial movement seat 405 can slide on the base frame 401 by the upward telescopic movement of the radial telescopic cylinders 404.

[0034] The lateral movement assembly 42 includes a lateral slide groove 420 disposed on the top of the radial movement seat 405. A lateral moving seat 421 is slidably disposed in the lateral slide groove 420. In this embodiment, the cross-section of the lateral slide groove 420 and the lateral moving seat 421 is a T-shaped sliding fit structure. A lateral telescopic cylinder 422 is disposed on the side of the radial movement seat 405, and a lateral moving connector 423 is disposed on the side of the lateral moving seat 421. In this embodiment, the lateral moving connector 423 is specifically L-shaped, with one end connected to the side of the lateral moving seat 421, and the telescopic end of the lateral telescopic cylinder 422 connected to the side of the other end of the lateral moving connector 423. Thus, the lateral moving seat 421 is controlled to move laterally in the lateral slide groove 420 by the telescopic movement of the lateral telescopic cylinder 422.

[0035] The angle adjustment assembly 43 includes a slewing bearing 430 located at the top center of the transverse support 421. The slewing bearing 430 includes a fixed support shaft and a rotating shaft rotatably disposed therein. This is prior art for the slewing bearing 430, so it will not be described in detail here. A rotary table 432 is mounted on the rotating shaft of the slewing bearing 430. Both ends of the top of the transverse support 421 are provided with rotary grooves 431. The bottom of the rotary table 432 is provided with an arc-shaped support block 433 that slides with the rotary groove 431, so that the rotary table 432 can rotate stably on the top of the transverse support 421. At the same time, the length of the arc-shaped support block 433 meets the rotation requirements of the rotary table 432.

[0036] A fixed gear ring 434 is provided on the outside of the fixed support shaft of the slewing bearing 430. A rotary drive device 435 is provided on the side of the rotary table 432. The rotary drive device 435 is composed of a motor and a reducer. A drive gear 436 that meshes with the fixed gear ring 434 is provided on its output shaft. Thus, the rotary drive device 435 can drive the drive gear 436 to rotate. Through its meshing with the fixed gear ring 431, the rotary table 432 can rotate. At the same time, through the gear engagement, high-precision rotation angle adjustment can be achieved.

[0037] The limiting component 44 consists of four columns arranged in a trapezoidal shape, with an arc-shaped limiting groove between them for placing the arc-shaped piece 1010. This groove restricts the arc-shaped piece 1010 to a vertical position within the groove, and its position and angle are adjusted by the radial moving component 40, the lateral moving component 42, and the angle adjusting component 43.

[0038] The height adjustment assembly 45 includes a receiving groove 451 disposed on the top of the rotary table 432 and a lifting platform 452 movably disposed in the receiving groove 451. When the lifting platform 452 is located in the receiving groove 451, its top surface is flush with the top surface of the rotary table 432. The lifting platform 452 is also provided with a groove 454 for avoiding the rotary drive device 435. The top of the rotary table 432 is provided with a plurality of lifting telescopic cylinders 450. In this embodiment, the number of lifting telescopic cylinders 450 is four, and their specific positions are located outside the arc-shaped limiting groove to avoid affecting the installation of the arc-shaped piece 1010. The top of the lifting platform 452 is provided with a lifting connector 453. The lifting connector 453 is inverted L-shaped, and its horizontal plate is connected to the telescopic end of the corresponding lifting telescopic cylinder 450. Thus, the lifting platform 452 can be raised and lowered by the telescopic movement of the lifting telescopic cylinder 450, thereby adjusting the height of the arc-shaped piece 1010. With this design, the arc-shaped piece 1010 can be automatically positioned for installation in a confined space through the installation mechanism 4.

[0039] In the preferred embodiment, in order to enable the arc-shaped piece 1010 to be inserted more accurately into the limiting component 44 of the mounting mechanism 4, a row of vertical lowering guide components 5 are provided on each of the two adjacent lifting devices 2, which are fixed on the top of the vertical frame 202 and the crossbeam 203 respectively, for continuous radial and circumferential positioning guidance of the arc-shaped piece 1010, ensuring that it can be accurately inserted into the limiting component 44.

[0040] The lowering guide component 5 includes a guide seat 501. A guide groove 502 is provided on one side edge of the guide seat 501 near the cylindrical section 101. The arc-shaped piece 1010 achieves its positioning effect by passing through the left and right guide grooves 502. The top of the guide groove 502 of the uppermost lowering guide component 5 is provided with an alignment slope 503, which makes it easy for the arc-shaped piece 1010 to slide into the guide groove 502 through the alignment slope 503, thereby passing through the lowering guide component 5 in sequence until it is lowered into the installation mechanism 4.

[0041] In the preferred embodiment, two guide grooves 502 are provided on the side edge of the guide seat 501 near the cylindrical section 101, corresponding to the arc-shaped pieces 1010 on both sides respectively, so as to position and guide the arc-shaped pieces 1010 on both sides.

[0042] It should be noted that the above-mentioned telescopic cylinder can be an electric telescopic cylinder or a hydraulic telescopic cylinder, and is equipped with a corresponding control system.

[0043] Example 2 Further explanation in conjunction with Example 1, such as Figure 17-26 The structure shown illustrates a method for installing a large-diameter storage tank and an isolation liner simultaneously. The method includes: S1. Complete the installation of the top first ring section 101 on the foundation concrete and place the flexible liner 11 inside it.

[0044] S2. Install the truss of the tank top 102 on the cylindrical section 101 of the first ring, and at the same time suspend the top of the flexible inner liner 11 onto the truss, and then complete the installation of the top cover and accessories of the tank top 102 on the truss.

[0045] S3. Install lifting devices 2 and installation mechanisms 4 around the first ring section 101, and install temporary lifting parts 3 at the bottom of the vertical overlap of the section 101. Connect half of the equidistant lifting devices 2 to the lifting parts 3, and then lift the first ring section 101 through the lifting devices 2. The lifting height needs to meet the installation requirements of the second ring section 101.

[0046] S4. Using hoisting equipment, hoist the arc-shaped piece 1010 through the fan-shaped gap area between the lifting device 2 and the cylinder section 101, and place it on the lifting device 2. Then, use the lifting device 2 to adjust the arc-shaped piece 1010 to its installation position, ensuring its top overlaps with the upper cylinder section 101 before fixing it. Repeat this step to install the remaining arc-shaped pieces 1010 one by one, ensuring that the arc-shaped pieces 1010 in the same layer form a connection structure with one side overlapping externally and the other side overlapping internally, until the second ring cylinder section 101 is installed. Figure 17 As shown, when installing the last arc-shaped piece 1010 of the cylindrical section 101, since its opening is smaller than the arc-shaped piece 1010 and both ends need to form inner and outer overlaps, during installation: rotate it to the installation angle and push it radially to the installation position, then move the arc-shaped piece 1010 towards the outer overlap side so that the inner overlap side can pass through the opening, then push it radially to the installation position, and then move it laterally in the opposite direction so that the overlaps on both sides are in place, and finally adjust its height so that the top overlap is aligned with the upper cylindrical section 101.

[0047] Furthermore, during the fixing process of the arc-shaped piece 1010, the fixing pieces 110 distributed in an annular pattern on the outside of the flexible inner liner 11 are fixed together with the upper and lower overlapping parts of the corresponding cylindrical section 101, and the installation of the ring lifting member 3 is completed at the same time.

[0048] It should be noted that, due to the presence of vertical overlaps, and to avoid stress concentration, the vertical overlaps of the upper and lower sections 101 are staggered, as follows: Figure 26 As shown, a reinforcing plate 150 is provided at the intersection.

[0049] S5. Connect the other half of the lifting devices 2 to the lifting member 3 of the second ring cylinder 101 and tighten them under force.
