[0002] With the rapid development of industries such as grain storage and petrochemical industry, the construction demand for large vertical storage tanks is increasing day by day. Traditional construction methods include the upright construction method or the reverse construction method. The upright construction method requires a large number of high-altitude operation platforms, which has problems such as long construction periods, high safety risks, and high temporary support costs. The existing reverse construction technology has been widely used in the field of storage tank construction due to its advantages such as high safety and fast construction efficiency.

[0019] Furthermore, a water-swellable waterstop strip is arranged below the first adsorption device. After the first adsorption device is fixedly connected to the side wall of the storage tank, the water-swellable waterstop strip is closely attached to the side wall of the storage tank.

Weld the first ring of wall plates of the side wall of the storage tank, and then weld the storage tank ceiling; install the first awning device around the storage tank, install the welding system inside the first awning device, and set up a jacking system inside the storage tank;

[0022] When it rains, or when the humidity content in the air exceeds a preset value, or when the wind force exceeds a preset value, the first telescopic device drives the first adsorption device to move and fixedly connect with the side wall of the storage tank, so that the first rain cloth encloses a relatively enclosed space;

[0023] The welding system performs welding operations within the space enclosed by the first rain cloth.

[0026] Furthermore, the first rain shelter device further includes a first slide rail, a first diagonal brace and a first drive device; the first slide rail is arranged along the length direction of the first column; one end of the first diagonal brace can slide along the first slide rail, and the other end is hinged to the first rain shelter beam; the first drive device can drive one end of the first diagonal brace to slide along the first slide rail to unfold or retract the first rain shelter beam;

[0045] The following further describes in detail a storage tank construction system and method provided by the present invention in conjunction with the accompanying drawings and specific embodiments. In combination with the following description, the advantages and features of the present invention will be clearer. It should be noted that the accompanying drawings are all in a very simplified form and use non-precise scales, only for conveniently and clearly assisting in explaining the purpose of the embodiments of the present invention.

[0046] Embodiment 1

[0047] As Figure 1 and Figure 2As shown in the figure, the storage tank construction system provided in this embodiment includes a jacking system 10, a welding system 20, and a canopy system 30, which are used to solve the problem that the welding quality is affected in rainy or windy weather.

[0048] The jacking system 10 can be implemented using existing technologies. For example, in the construction of the storage tank by the reverse installation method, the jacking system 10 mainly includes: an expansion ring, a clamping plate, and a hydraulic lifting device. The hydraulic lifting device mainly includes a pump station, a hydraulic cylinder, a jacking rod, a jacking chain, etc. In the construction of the storage tank by the reverse installation method, first, the bottom plate of the storage tank is welded, and then the side wall 1 of the storage tank is constructed. The side wall 1 of the storage tank includes several rings of wall plates, and each ring of wall plates is formed by welding several arc-shaped plates in sequence to form a ring. After the first ring of wall plates is welded, the storage tank ceiling 2 is welded, and then through the jacking system 10, the first ring of wall plates of the side wall 1 of the storage tank together with the storage tank ceiling 2 is lifted, and then several arc-shaped steel plates of the second ring of wall plates of the side wall 1 of the storage tank are welded to the arc-shaped steel plates of the first ring of wall plates, and the adjacent arc-shaped steel plates of the second ring of wall plates are welded together.

[0049] Combined with Figures 1 to 3 As shown in the figure, the welding system 20 mainly includes a guide rail 21, a welding base 22, a welding robot arm 23, and a welding head 24. The guide rail 21 is arranged in a circular ring around the storage tank. The welding base 22 can move along the guide rail 21. One end of the welding robot arm 23 is fixedly connected to the welding base 22, and the other end is connected to the welding head 24. The welding head 24 is used for welding. Preferably, the welding head 24 can automatically identify the splicing seam, and the extension of the robot arm and the welding construction of the welding head are controlled by setting a controller. The welding head 24 automatically identifies the splicing seam, which can be realized based on image recognition technology or based on machine deep learning technology. Further, a welding slag catching hopper 25 is arranged at the front end of the welding robot arm. The side of the welding slag catching hopper 25 is connected to a compression spring 26. The welding slag catching hopper is pressed tightly against the side wall of the storage tank by the pressure of the compression spring 26, which is used to catch the welding slag splashed and dropped during the welding process.

[0050] Combined with Figures 1 to 4As shown, the canopy system 30 includes a first canopy device 31, and the first canopy device 31 includes a first column 311, a first canopy beam 312, a first rain cloth 313, a first telescopic device 314 and a first adsorption device 315. The first column 311 is vertically arranged. One end of the first canopy beam 312 is connected to the first column 311, and the other end is provided with a first telescopic device 314. The first telescopic device 314 is connected with a first adsorption device 315. A number of first columns 311 are arranged at intervals around the storage tank. The first columns 311 and the first canopy beam 312 form the framework of the first rain cloth, and the first rain cloth 313 covers the first canopy beam 312 and the first columns 311. The first telescopic device 314 can drive the first adsorption device 315 to move and fixedly connect with the side wall of the storage tank, and can also make the first adsorption device 315 move and separate from the side wall of the storage tank. As an example, the first adsorption device 315 can adopt a power-off type electromagnet, which can adsorb on the side wall of the storage tank when the circuit is powered off. When the circuit is powered on, the electromagnet is demagnetized, which is convenient for separating the first adsorption device 315 from the side wall of the storage tank through the first telescopic device 314. The first adsorption device 315 can also adopt a suction cup. The suction cup is pushed by the first telescopic device 314 to abut against and adsorb on the side wall of the storage tank, and is pulled by the first telescopic device 314 to separate the suction cup from the side wall of the storage tank. By way of example and not limitation, in combination with Figure 3 and Figure 4 As shown, the first telescopic device 314 includes a sleeve, a telescopic rod and a spring. The first adsorption device 315 adopts a power-off type electromagnet. One end of the telescopic rod is fixedly connected to the electromagnet, and the other end of the telescopic rod is inserted into the sleeve. The sleeve is fixedly connected to the first canopy beam 312. The spring is sleeved on the sleeve, and both ends of the spring are fixedly connected to the first canopy beam 312 and the electromagnet respectively. The suction force between the electromagnet and the side wall of the storage tank can cause the spring to stretch. The spring stores energy due to elastic deformation. The electromagnet moves towards the side wall 1 of the storage tank and adsorbs on the side wall 1 of the storage tank. After the electromagnet is demagnetized, under the pulling force of the spring, the electromagnet moves a certain distance towards the first canopy beam 312 to separate the electromagnet from the side wall 1 of the storage tank.

[0051] The storage tank construction system provided in this embodiment can drive the first adsorption device 315 to move and fix it to the storage tank through the first telescopic device 314. The first canopy device 31 encloses the storage tank on all sides and forms a relatively enclosed space, enabling the welding system 20 to perform welding operations in a windless and rainless environment, thereby ensuring the weld quality. In addition, through the first telescopic device 314, the first adsorption device 315 can be controlled to move and separate from the storage tank, without interfering with the jacking operation of the jacking system 10 on the side wall 1 of the storage tank.

[0052] In a specific embodiment, the storage tank construction system further includes a humidity adjustment system 40. When the first adsorption device 315 of the first awning device 31 adsorbs on the side wall of the storage tank, humidity adjustment is performed through the humidity adjustment system 40 to make the air humidity in the space enclosed by the first awning device meet the welding requirements of the storage tank.

[0053] In a specific embodiment, the first awning device 31 further includes a first slide rail 316, a first diagonal brace 317, and a first driving device 318. The first slide rail 316 is arranged along the length direction of the first upright column 311; one end of the first diagonal brace 317 can slide along the first slide rail 316, and the other end is hinged to the first awning beam 312; the first driving device 318 can drive one end of the first diagonal brace 317 to slide along the first slide rail 316 to unfold or retract the first awning beam 312. When it is sunny, the first awning beam 312 can be retracted, and the welding operation is carried out outdoors; when it is raining, the first awning beam 312 can be unfolded, and the welding operation is carried out in a relatively enclosed space.

[0054] In a specific embodiment, during the process of the lifting system 10 lifting the storage tank, the first adsorption device 315 of the first awning device 31 is separated from the storage tank. Therefore, during the lifting process, rainwater may enter the first awning, affecting the air humidity inside the first awning, increasing the working load of the humidity adjustment system 40, and the rainwater may also flow down along the side wall 1 of the storage tank to the end face to be welded. It is necessary to clean the rainwater before welding, reducing the construction speed. Therefore, it is necessary to solve the sealing problem of the awning system during the lifting process. Specifically, in combination with Figures 1 to 5As shown, the awning system further includes a second awning device 32, and the second awning device 32 includes a second column 321, a second awning beam 322, a second awning cloth 323, a second telescopic device 324 and a second adsorption device 325. The first column 311 is made of a hollow pipe. The second column 321 is vertically arranged and its bottom is inserted into the first column 311. A lifting drive mechanism 329 is arranged between the first column 311 and the second column 321, and the lifting drive mechanism 329 can lift the second awning device 32 upward. The connection relationship between the components of the second awning device 32 can refer to that of the first awning device 31. During the process of the lifting system 10 lifting the storage tank, the first adsorption device 315 of the first awning device 31 is separated from the side wall of the storage tank, and the second adsorption device 325 of the second awning device 32 is fixed to the side wall of the storage tank. The lifting drive mechanism 329 makes the rising speed of the second column 321 consistent with the lifting speed of the lifting system 10 for the storage tank, so as to keep the second adsorption device 325 stably connected to the side wall of the storage tank during the lifting process of the storage tank. After the lifting system 10 is lifted in place, the first adsorption device 315 of the first awning device 31 is fixed to the side wall of the storage tank, and the second adsorption device 325 of the second awning device 32 is separated from the side wall of the storage tank. The lifting drive mechanism 329 makes the second column 321 descend to the initial height. By alternately fixing the first awning device 31 and the second awning device 32 to the side wall of the storage tank, a relatively enclosed space can be maintained during both the welding operation and the lifting operation of the storage tank, rainwater will not flow to the bottom end face to be welded, the influence of rainwater on the humidity of the enclosed space is limited, and the working load of the humidity adjustment system 40 can also be reduced, which is convenient for controlling the air humidity.

[0055] In a specific embodiment, the second awning device 32 further includes a second slide rail 326, a second diagonal brace 327 and a second drive device 328. The second slide rail 326 is arranged along the length direction of the second column 321; both ends of the second diagonal brace 327 can slide along the second slide rail 326, and the other two ends are hinged to the second awning beam 322; the second drive device 328 can drive both ends of the second diagonal brace 327 to slide along the second slide rail 326 to unfold or retract the second awning beam 322. When it is sunny, the first awning beam 312 and the second awning beam 322 can be retracted, and the welding operation is carried out outdoors; when it is raining, the first awning beam 312 and the second awning beam 322 can be unfolded, and the welding operation is carried out in a relatively enclosed space.

[0056] In a specific embodiment, the layout drawings of the bottom plate, side wall and top ceiling of the storage tank are optimized through an optimization algorithm. For example, a genetic algorithm can be used to solve the optimal plate layout scheme. The algorithm principle is that when arranging the plates, it is required that the longitudinal welds of each ring of wall plates are staggered one by one in the same direction, and the longitudinal welds of each ring of wall plates should be staggered one by one in the same direction to ensure the minimum welding stress and the shortest welding length.

[0057] In a specific embodiment, the welding system adopts a programmed welding robot system, and through a pre-optimized welding sequence parameter database, precise control of the weld path and heat input is achieved.

[0058] In a specific embodiment, a water-swellable waterstop strip 319 is also provided below the first adsorption device 315. The first telescopic device 314 can drive the first adsorption device 315 to move and fixedly connect with the side wall of the storage tank. The water-swellable waterstop strip 319 also clings to the side wall of the storage tank. The water-swellable waterstop strip 319 will expand when encountering water, filling the gap tightly, thus playing a role in strengthening waterstop. Similarly, a water-swellable waterstop strip 319 can also be provided below the second adsorption device 325.

[0059] In a specific embodiment, water collecting troughs can be provided at the ends of the first awning beam 312 and the second awning beam 322 to collect and drain the rainwater on the first raincloth 313 and the second raincloth 323 respectively.

[0060] Embodiment Two

[0061] This embodiment also provides a method for constructing a storage tank, adopting the above-mentioned storage tank construction system. The method for constructing the storage tank includes:

[0062] Step 1: The storage tank is constructed by the reverse installation method. Weld the first ring of wall plates of the side wall 1 of the storage tank, and then weld the storage tank ceiling 2. Install the first awning device 31 around the storage tank, install the welding system 20 inside the first awning device 31, and install the jacking system 10 on the inner side of the side wall of the storage tank.

[0063] The bottom plate of the storage tank is constructed first and subjected to non-destructive testing. The arc-shaped steel plates of each ring of wall plates of the side wall 1 of the storage tank can be pre-placed on the bottom plate of the storage tank, and hoisting equipment is used for hoisting, transporting and positioning. Then, the first ring of wall plates is welded by the welding system 20. Then, hoisting equipment is used for hoisting, transporting and positioning the storage tank roof, and the storage tank roof is welded to form the storage tank ceiling. Then, the jacking system 10 is used to jack up the first ring of wall plates of the side wall 1 of the storage tank and the storage tank ceiling. After jacking in place, hoist the arc-shaped steel plates of the second ring of wall plates. The longitudinal welds of the arc-shaped steel plates of each ring should be staggered in the same direction ring by ring. After the second ring of arc-shaped steel plates is welded, non-destructive testing is carried out. The welding system 20 and the jacking system 10 work alternately to complete the construction of the storage tank. The maximum working stroke of the jacking system 10 needs to be greater than or equal to the maximum height of the arc-shaped steel plate. For example, the maximum working stroke of the jacking system 10 is 3.5 m, and the height of the highest arc-shaped steel plate is 3 m.

[0064] Step 2: When it is raining or the humidity content in the air exceeds the preset value or the wind force exceeds the preset value, the first telescopic device 314 is driven to drive the first adsorption device 315 to move and fixedly connect with the side wall of the storage tank, so that the first raincloth 313 encloses a relatively enclosed space.

[0065] Step 3: The welding system 20 performs welding operations within the space enclosed by the first raincloth 313. The awning system has the function of preventing wind and rain, ensuring that the construction of the storage tank does not stop during windy and rainy weather.

[0066] In a specific embodiment, the awning system further includes a second awning device 32. The second awning device 32 includes a second column 321, a second awning beam 322, a second raincloth 323, a second telescopic device 324, and a second adsorption device 325. The first column 311 is made of a hollow pipe. The second column 321 is vertically arranged and its bottom is inserted into the first column 311. A lifting drive mechanism 329 is provided between the first column 311 and the second column 321. The lifting drive mechanism 329 can move the second awning device 32 up and down. The connection manner between the structures of the second awning device 32 refers to the connection manner between the corresponding structures of the first awning device 31.

[0067] Before using the jacking system 10 to jack up the storage tank, first separate the first adsorption device 315 of the first awning device 31 from the side wall of the storage tank, fixedly connect the second adsorption device 325 of the second awning device 32 to the side wall of the storage tank, and use the lifting drive mechanism 329 to move the second column 321 upward at the same speed as the jacking speed of the jacking system 10. The second raincloth 323 encloses a relatively closed space around the storage tank.

[0068] In a specific embodiment, the first awning device 31 further includes a first slide rail 316, a first diagonal brace 317, and a first drive device 318. The first slide rail 316 is arranged along the length direction of the first column 311. One end of the first diagonal brace 317 can slide along the first slide rail 316, and the other end is hinged to the first awning beam 312. The first drive device 318 can drive one end of the first diagonal brace 317 to slide along the first slide rail 316 to unfold or retract the first awning beam 312. The second awning device 32 further includes a second slide rail 326, a second diagonal brace 327, and a second drive device 328. The second slide rail 326 is arranged along the length direction of the second column 321. Two ends of the second diagonal brace 327 can slide along the second slide rail 326, and the other two ends are hinged to the second awning beam 322. The second drive device 328 can drive the two ends of the second diagonal brace 327 to slide along the second slide rail 326 to unfold or retract the second awning beam 322.

[0069] The storage tank construction system further includes a meteorological monitoring system.
