[0031] To enable those skilled in the art to better understand this application, the technical solution of this application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] like Figure 1 As shown, the tank wall jacking construction equipment (hereinafter referred to as construction equipment) in this application embodiment includes a jacking device 1 and a hydraulic supply device 2.

[0033] The lifting device 1 includes a rod 11, a telescopic drive 12, and a bracket 13, with the telescopic drive 12 connected between the rod 11 and the bracket 13. For example, Figure 2 As shown, the rod 11 can be a hollow circular tube structure, the rod 11 can extend in the vertical direction, and the material of the rod 11 can be a high-strength metal such as stainless steel.

[0034] The telescopic drive 12 can be a hydraulic cylinder or other hydraulically driven mechanism. The telescopic drive 12 can extend or retract in the vertical direction. The top end of the telescopic drive 12 can be connected and fixed to the rod 11, and the bottom end of the telescopic drive 12 can be connected and fixed to the bracket 13. The bracket 13 can be a cylindrical structure, and the axial direction of the bracket 13 can also be vertical. The top end of the bracket 13 can be directly connected to the bottom end of the telescopic drive 12.

[0035] It should be noted that each direction in this application can be the corresponding position of the construction equipment in actual use. The lifting device 1 can be arranged vertically, and the vertical direction is the up and down direction. The left side from bottom to top is left, the right side from bottom to top is right, the front side from bottom to top is front, and the rear side from bottom to top is rear.

[0036] The rod 11 is provided with a locking part 111, which is used to limit and fix the rod 11. For example, as Figure 2 As shown, the snap-fit ​​part 111 can be integrally formed on the outer periphery of the rod body 11. The snap-fit ​​part 111 can be a protrusion, bump, or other structure provided on the outer periphery of the rod body 11. In use, the rod body 11 can be hung and fixed by the snap-fit ​​part 111 and the stop limit of the set plane, etc., thereby realizing the installation and fixation of the top of the lifting device 1.

[0037] The support 13 is provided with a top support 131, which is detachably connected to the tank wall of the storage tank to lift the tank wall when the telescopic drive 12 retracts. For example, as Figure 2 As shown, the top support 131 can be integrally formed on the outer periphery of the bracket 13, or the top support 131 can be a protrusion, bump, or other structure provided on the outer periphery of the bracket 13.

[0038] The inner circumference of the tank wall can be provided with a groove or other structure, which can be formed by welding channel steel, steel plate, etc. In use, the top support 131 can be inserted into the groove, thereby achieving the connection and fixation of the bracket 13 and the tank wall. Then, the telescopic drive 12 can be driven to retract. Since the top of the lifting device 1 can be considered to be fixed in position under the limiting action of the locking part 111, the bracket 13 together with the top support 131 will move upward under the action of the telescopic drive 12, thereby achieving the upward lifting of the tank wall.

[0039] The hydraulic supply device 2 is connected to the telescopic drive 12, and the hydraulic supply device 2 is used to supply hydraulic fluid to the telescopic drive 12 to achieve telescopic adjustment drive of the telescopic drive 12. For example, as Figure 2 As shown, the hydraulic supply device 2 can be a hydraulic pump assembly, etc., and can be connected to the telescopic drive 12 through corresponding pipelines. In use, the hydraulic supply device 2 can deliver hydraulic oil or other hydraulic fluid to the telescopic drive 12, thereby enabling the extension or retraction of the telescopic drive 12 under hydraulic pressure.

[0040] In some embodiments, the locking portion 111 is annular and extends around the circumference of the rod 11, and the locking portion 111 is used to engage with a stop at a set position to achieve the suspension arrangement of the lifting device 1.

[0041] For example, such as Figure 2As shown, the snap-fit ​​part 111 can be integrally formed on the outer periphery of the rod 11. The snap-fit ​​part 111 can extend along the circumferential direction of the rod 11. In use, the inner side of the storage tank can be fixed with a column or other structure, and the snap-fit ​​part 111 can be hung on the top of the column or other positions, thereby facilitating the suspension and fixing of the top of the lifting device 1.

[0042] In some embodiments, the construction equipment further includes a support frame (not shown), which is fixed to the ground. A lifting device 1 is assembled inside the support frame and is suspended from the support frame by a snap-fit ​​part 111. For example, the support frame can be assembled and welded from a structure such as channel steel. The bottom end of the support frame can be directly fixed to the ground, and the support frame can extend in the vertical direction.

[0043] The support frame can be hollow inside, and the lifting device 1 can be installed inside the support frame. The snap-fit ​​part 111 on the rod 11 can be suspended from the top of the support frame. The front side of the support frame can be provided with a slot, which can extend along the extension direction of the support frame. The top support part 131 of the bracket 13 can be exposed from the slot of the support frame, thereby facilitating the insertion and positioning of the top support part 131 and the tank wall to be lifted of the storage tank.

[0044] In some embodiments, the top support 131 protrudes from the outer peripheral wall of the bracket 13 and extends circumferentially along the bracket 13. The bracket 13 is cylindrical, and the top support 131 is annular or semi-annular. This allows for circumferential suspension limiting, thereby improving the structural stability of the suspension arrangement.

[0045] In some embodiments, the telescopic drive 12 includes a cylinder 121 and a piston rod 122. The cylinder 121 is connected to the rod 11. An injection valve 123 is provided on the outer periphery of the cylinder 121. The injection valve 123 is connected to the hydraulic supply device 2 through a connecting pipe 3. The injection valve 123 is used to allow the hydraulic fluid provided by the hydraulic supply device 2 to flow into the cylinder 121. The piston rod 122 is slidably assembled in the cylinder 121. The end of the piston rod 122 away from the rod 11 is fixedly connected to the bracket 13.

[0046] For example, such as Figure 3 As shown, the cylinder body 121 can be an annular cylindrical shape, and the top end of the cylinder body 121 can be closed, and the top end of the cylinder body 121 can be connected and fixed to the bottom end of the rod body 11. The bottom end of the cylinder body 121 can be open, and the piston rod 122 can be assembled into the cylinder body 121 from the bottom side, and the piston rod 122 can slide back and forth in the vertical direction relative to the cylinder body 121, thereby meeting the needs of telescopic drive 12 for telescopic adjustment.

[0047] like Figure 3As shown, a hydraulic injection valve 123 may be provided on the outer periphery of the cylinder body 121. Specifically, the hydraulic injection valve 123 may be located at the bottom of the cylinder body 121. In use, the hydraulic injection valve 123 can deliver hydraulic oil and other fluids into the cylinder body 121. The hydraulic injection valve 123 may be a one-way valve, thereby preventing the hydraulic fluid from flowing back into the hydraulic supply device 2.

[0048] The piston rod 122 can be extended along the vertical direction. The bottom end of the piston rod 122 can be directly connected and fixed to the bracket 13. Thus, when the piston rod 122 moves up and down, it can drive the bracket 13 and the top support 131 to move up and down, thereby meeting the needs of lifting the tank wall.

[0049] In some embodiments, the end of the piston rod 122 facing away from the rod body 11 is provided with a connecting flange 1221, and the piston rod 122 is fixedly connected to the bracket 13 through the connecting flange 1221. For example, Figure 3 As shown, the connecting flange 1221 can be integrally formed on the bottom end of the piston rod 122. The connecting flange 1221 can be provided with multiple through holes, which can be arranged at intervals along the circumference of the connecting flange 1221.

[0050] During assembly, a fixing bolt 124 can be installed in each through hole. The fixing bolt 124 can be used to connect and fix the connecting flange 1221 and the bracket 13, thereby ensuring the stability of the connection and the balanced force in all directions in the circumferential direction, which fully meets the needs of bearing large loads during lifting.

[0051] In some embodiments, the cylinder body 121 is provided with a nitrogen spring 125, which protrudes from the inner peripheral wall of the cylinder body 121 and is used to buffer the sliding of the piston rod 122. The cylinder wall of the cylinder body 121 is provided with a mounting hole for mounting the nitrogen spring 125, and a stop 126 is provided at the mounting hole for blocking the mounting hole.

[0052] For example, such as Figure 3 As shown, the cylinder wall of the cylinder body 121 may be provided with mounting holes that can penetrate the cylinder wall radially along the cylinder body 121, and the nitrogen spring 125 can be assembled into the cylinder body 121 through the mounting holes. When the piston rod 122 reciprocates relative to the cylinder body 121, the nitrogen spring 125 can buffer the piston cylinder.

[0053] Each mounting hole is also equipped with a stop 126, which may include a locking pin 1261 and a stop block 1262. The locking pin 1261 can be fixed in the mounting hole, and the stop block 1262 can be located on the outer periphery of the cylinder wall of the cylinder body 121, thereby sealing the opening at the outer end of the mounting hole and preventing the nitrogen spring 125 from being exposed.

[0054] In some embodiments, the hydraulic supply device 2 includes a storage container 21 and a movable base 22. The storage container 21 is used to store hydraulic fluid. The storage container 21 is provided with a control valve 23 and an electronic control component 24. The control valve 23 is connected to the injection valve 123 through a connecting pipe 3. The electronic control component 24 is used to monitor the displacement of the piston rod 122. The movable base 22 is located on the bottom side of the storage container 21 and includes movable wheels 221 to facilitate the movement of the hydraulic supply device 2.

[0055] For example, such as Figure 4 As shown, the storage container 21 can be a tank-like structure, and can store hydraulic fluids such as hydraulic oil. The control valve 23 can be installed on the front side of the storage container 21, and can be directly connected to the injection valve 123 via the connecting pipe 3. Both the injection valve 123 and the control valve 23 are one-way valves. Therefore, the control valve 23 and the injection valve 123 can operate as a system, allowing the hydraulic fluid to flow in a preset direction, thereby ensuring the stability and reliability of the hydraulic system.

[0056] like Figure 4 As shown, a movable base 22 can be provided at the bottom of the storage container 21. The movable base 22 can include a chassis and four movable wheels 221. The storage container 21 can be fixed on the chassis, and the four movable wheels 221 can be installed on the chassis, thereby facilitating the movement of the hydraulic supply device 2.

[0057] like Figure 4 As shown, an electrical control component 24 may also be provided on the outer periphery of the storage container 21. The electrical control component 24 may include an electrical control box 243, a control system 241, and a sensing system 242. The electrical control system and the sensing system 242 may both be installed in the electrical control box 243. The electrical control system may be a control system 241 with calculation and processing functions. The sensing system 242 may include some sensors, etc. The sensing system 242 may be mainly used to monitor the displacement of the piston cylinder of the telescopic drive 12 and the pressure change of the internal hydraulic fluid.

[0058] During use, the telescopic drive 12's extension and retraction amount and internal pressure changes can be monitored through the sensor system 242. This monitoring data can be transmitted to the control system 241. By analyzing this data, the control system 241 can adjust the lifting speed and height of the telescopic drive 12 in real time, thereby ensuring the synchronization and stability of the lifting process. The core of the hydraulic lifting device 1 can adopt a closed-loop control method, which continuously adjusts the flow rate and direction of the hydraulic oil to ensure the synchronization between the hydraulic cylinders.

[0059] In some embodiments, there are multiple lifting devices 1, and the extension and retraction drives 12 of each lifting device 1 are connected to the hydraulic supply device 2. The tank wall can be annular, and in use, multiple lifting devices 1 can be arranged on the inner side of the tank wall and can be arranged at equal intervals along the circumference of the tank wall. The top support portion 131 of each lifting device 1 can be inserted and limited with the tank wall. When the hydraulic supply device 2 supplies hydraulic fluid, the multiple lifting devices 1 can extend and retract synchronously, thereby meeting the needs of lifting the tank wall.

[0060] The following describes a specific example of the construction equipment used in this application.

[0061] The construction equipment in this application is mainly used for constructing natural gas (LNG) storage tanks. The construction equipment includes a jacking device 1 and a hydraulic supply device 2.

[0062] The lifting device 1 includes a rod 11, a telescopic drive 12, and a bracket 13. The rod 11 is cylindrical, and a locking part 111 is provided on the outer upper part of the rod 11. The telescopic drive 12 is connected between the rod 11 and the bracket 13. The bottom of the bracket 13 is provided with a top support part 131, which is annular or semi-annular. Preferably, an expansion ring is also provided on the outside of the rod 11.

[0063] The telescopic drive 12 includes a cylinder 121 disposed above the bracket 13 and a piston rod 122 sleeved inside it. A stop 1262 is disposed on the outer side of the cylinder 121. A locking pin 1261 connected to the stop 1262 is embedded in the cylinder 121. A nitrogen spring 125 is disposed on the side of the locking pin 1261 away from the stop 1262, which is inside the telescopic drive 12.

[0064] A one-way injection valve 123 is fixed at the bottom of the cylinder body 121 to ensure unidirectional flow of the medium and prevent backflow. The injection valve 123 and the control valve 23 are stably connected through the connecting pipe 3. This pipeline layout enables the control valve 23 and the injection valve 123 to work together to ensure that the medium in the hydraulic system flows in the preset direction, effectively improving the stability and reliability of the hydraulic system.

[0065] The piston rod 122 has a fixing bolt 124 at its bottom and a connecting flange 1221 on its bottom side. The connecting flange 1221 is arranged in a ring. The bottom of the piston rod 122 is fixedly connected to the bracket 13 by the fixing bolt 124, the connecting flange 1221 and the connecting flange 1221. This makes installation and disassembly very convenient. In addition, the ring-shaped connecting flange 1221 with equal spacing not only makes the force more even, but also improves the working stability of the piston rod 122. It can also adapt to more connection scenarios, enhance the versatility of the structure, and ensure that the piston rod 122 can be stably connected to other components under various working conditions to maintain the efficient operation of the equipment.

[0066] The piston rod 122 is fixed to the bracket 13 by fixing bolts 124 and connecting flange 1221. The piston rod 122 is fixedly connected to the connecting flange 1221 and bracket 13 by fixing bolts 124. The installation and operation are simple and easy to disassemble. This connection method can effectively distribute the force, improve the connection stability, ensure that the piston rod 122 and bracket 13 are stably matched during the operation of the equipment, and extend the overall service life of the equipment.

[0067] The hydraulic supply device 2 includes a storage container 21 and a movable base 22. The movable base 22 is located at the bottom of the storage container 21. One end of the storage container 21 is fixedly connected to a control valve 23. The movable base 22 is located at the bottom, which facilitates the overall movement and flexible deployment of the hydraulic supply device 2. The control valve 23 at one end of the storage container 21 can ensure the unidirectional flow of hydraulic oil, prevent backflow, improve the stability and efficiency of the hydraulic system, and make the hydraulic supply device 2 work more reliably.

[0068] The storage container 21 is also equipped with an electrical control component 24. The electrical control component 24 includes an electrical control box 243 located on one side of the storage container 21, a sensing system 242, and a control system 241. The sensing system 242 and control system 241 are sequentially located inside the electrical control box 243, used to monitor the displacement and pressure changes of the hydraulic cylinders and transmit the data to the control system 241. The control system 241 analyzes this data and adjusts the lifting speed and height of the telescopic drive 12 in real time to ensure the synchronization and stability of the lifting process. This is the core of the hydraulic lifting device 1, employing a closed-loop control method. By continuously adjusting the flow rate and direction of the hydraulic oil, it maintains synchronization between the hydraulic cylinders. When an abnormality is detected, the system can also automatically issue commands to close or open the corresponding hydraulic circuits to correct deviations.

[0069] When in use, the hydraulic lifting device can be evenly distributed on the inner circumference of the tank. First, lift the top and upper layer of the tank body so that it is located at the first layer and the top wall panel of the tank. Then, weld the wall panels of the tank body layer by layer.

[0070] Specifically, when the hydraulic jack (telescopic drive 12) is activated by the hydraulic supply device 2 to lift upwards, its locking part 111 clamps and lifts the rod 11 and the expansion ring, thereby driving the tank body, including the tank top, to be lifted upwards. Then, the lifted tank wall can be welded and fixed to the tank wall below. Then, the hydraulic fluid of the hydraulic jack can be released. At this time, the hydraulic jack extends, the top support 131 moves downwards, and then the telescopic drive 12 can be driven to retract. The top support 131 can drive the newly added tank wall, together with the tank wall above and the tank top, to be lifted.

[0071] The jack, through the repeated movement of the telescopic drive 12, can continuously raise the lifting device 1, carrying the tank body, until it reaches the predetermined height. After the welding is completed, the upper and lower release devices of the hydraulic jack are opened, the locking part 111 and the top support part 131 are released, and the rod 11 and the expansion ring are lowered to the lower wall of the next layer of wall panel, tightened, and the force transmission rib plate is welded, and then lifted again. This process is repeated to raise the already welded tank body until the wall panel of the last layer of tank body is welded, meeting the requirements of the inverted installation process.

[0072] Through the above embodiments, this application has the following beneficial effects or advantages:

[0073] This application provides a novel construction equipment for storage tanks. Each support part of the construction equipment is located on the bottom side of the lifting device, which allows for lifting and inverting operations in a similar manner during use. This provides better structural stability. Compared to electric hoists and other methods where control precision is difficult to guarantee, the multiple lifting devices in this application can move synchronously, ensuring the consistency of lifting in all directions. This, in turn, ensures overall construction efficiency, reduces the overall construction period, and meets the need for rapid construction of storage tanks.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of this application.

[0075] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application. Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
