Description

Technical Field

[0001] This utility model relates to the field of large storage tank wall panel installation technology, specifically to a storage tank wall panel loading device. Background Technology

[0002] Currently, the inverted installation method is widely used in the fabrication and installation of large steel tanks. Its advantages include low-altitude operation, eliminating the need for high-altitude platforms, and the completion of installation, splicing, welding, and inspection all on the ground. It is a relatively convenient construction method. When working on the ground, the installation of the wall panels is an important task of the main project, in addition to the top cover and bottom plate. The wall panels are usually loaded by crane around the tank. However, if the site is narrow, the foundation spacing is small, and a truck crane cannot enter, the loading of the steel tank wall panels becomes very difficult. Large-tonnage cranes with extended booms must be used to successfully deliver each ring of wall panels to the designated position, thereby increasing construction costs. Utility Model Content

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0034] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0035] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. In the detailed description of the embodiments of this utility model, for ease of explanation, the schematic diagrams may be partially enlarged without adhering to general proportions, and the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. Furthermore, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0036] In one or more embodiments of this utility model, please refer to Figures 1-2 This embodiment provides a tank wall plate loading device 100, which is applied to a steel storage tank 200. The tank wall plate loading device 100 includes: a truss mechanism 101; and a support mechanism 102 connected to one end of the truss mechanism 101.

[0037] A traveling mechanism 103 is connected to the end of the truss mechanism 101 away from the support mechanism 102; and a hoisting mechanism 104 is connected to the truss mechanism 101 near the support mechanism 102.

[0038] This utility model, employing the tank wall panel loading device 100, can significantly reduce the frequency of truck crane movement and mitigate the safety hazards caused by the truck crane's inability to deliver the wall panel to the designated position due to site limitations, requiring manual dragging. Furthermore, the tank wall panel loading device 100 is simple to manufacture, quick to install, and can be used immediately after being connected to power. It has a high reusability, adjustable length, is lightweight, and is safe and reliable.

[0039] In a preferred embodiment of this utility model, the support mechanism 102, the traveling mechanism 103, and the hoisting mechanism 104 are connected as a whole by a truss mechanism 101, and the traveling and hoisting of the tank wall plate loading device 100 is controlled by a remote control device. When the diameter of the steel storage tank 200 changes, the telescopic truss mechanism 101 can determine the length of the truss according to the tank radius.

[0040] To further explain, the truss mechanism 101 is telescopic and can extend 300mm-500mm beyond the edge of the steel storage tank 200. The truss mechanism 101 has an inverted triangular structure, with multiple crossbars 1013 connected to the center of the inverted triangle.

[0041] Specifically, the truss mechanism 101 includes a crossbeam 1011, a diagonal beam 1012, and a crossbar 1013;

[0042] The cross frame 1011 is connected to one end of the inclined beam 1012, and the other ends of the cross frame 1011 and the inclined beam 1012 are respectively connected to the upper and lower ends of the walking mechanism 103.

[0043] The crossbeam 1011 and the inclined beam 1012 form an inverted triangular structure. There are multiple crossbars 1013, which are connected to the middle of the inverted triangular structure. The crossbars 1013 are connected end to end in sequence and are slidably connected to the crossbeam 1011 and the inclined beam 1012 respectively.

[0044] The crossbeam 1011 and the inclined beam 1012 are both provided with grooves, and the crossbar 1013 is provided with pulleys at the corner points, which can slide along the grooves.

[0045] It should be noted that the truss mechanism 101 is specifically an inverted triangular telescopic rod. A groove structure is provided on the telescopic rod in the middle of the inverted triangular telescopic rod. A plurality of crossbars 1013 are provided on the crossbar 1013, which can be placed within and moved along the groove structure and fixed therein. The crossbars 1013 are bendable. When the telescopic rod extends along the horizontal plane, the crossbars 1013 extend along the groove structure; when the telescopic rod shortens along the horizontal plane, the crossbars 1013 shorten along the groove structure.

[0046] The specific implementation of fixing the pulley within the groove is as follows: multiple spring-loaded fixing blocks are fixed within the groove, the fixing blocks are spaced apart, and cooperate with the pulley for fixation. This allows the crossbar 1011 to be telescopically attached to any position on the side wall of the steel storage tank 200 for wall panel attachment.

[0047] In one embodiment of the present invention, the tank wall plate feeding device 100 further includes: a concave groove 105;

[0048] The concave groove 105 is formed on the crossbeam 1011 at one end away from the hoisting mechanism 104, and is used to cooperate with the hoisting mechanism 104.

[0049] It should be noted that the crossbeam 1011 and the inclined beam 1012 are not limited to having grooves, and the corner points of the crossbar 1013 are not limited to having pulleys. For example, ratchet wheels can be installed at intervals on both the crossbeam 1011 and the inclined beam 1012, and pawls can be installed at the corner points of the crossbar 1013. Similarly, the pawls and ratchet wheels can also cooperate to realize the truss mechanism 101. At the same time, the trouble of making grooves and installing pulleys is eliminated. In addition, it eliminates the need to fix multiple spring-loaded fixing blocks at intervals in the grooves, further saving labor costs and time costs.

[0050] It is understood that the invention is not limited to the grooves and pulleys, ratchet wheels and pawls described above. Any device that enables the truss mechanism 101 to be telescopic and movable, and that allows the interlocking of the crossbeams 1011, the inclined beams 1012 and the crossbars 1013 to smoothly install the wall panels at any position on the side wall of the steel storage tank 200, is within the protection scope of this utility model.

[0051] In another preferred embodiment of this utility model, the support mechanism 102 includes: a first support rod 107 perpendicular to the horizontal plane, and a plurality of second support rods 108 distributed around the first support rod 107; wherein the plurality of second support rods 108 can retract along the top end of the first support rod 107 and wrap around the first support rod 107. Specifically, the plurality of second support rods 108 wrap around the first support rod 107, the top ends of the first support rod 107 and the plurality of second support rods 108 are interlocked, and the lower ends of the second support rods 108 can be extended for support as needed.

[0052] Preferably, the first support rod 107 includes at least one rod, and the second support rod 108 includes at least four rods. Using one first support rod 107 in contact with the ground and four second support rods 108 surrounding the first support rod 107 can further increase the stability of the support mechanism 102, making the tank wall loading device 100 more stable and reliable during operation, and less prone to shaking.

[0053] It should be noted that a pivot is provided at the contact point between the support mechanism 102 and the truss mechanism 101. Specifically, the pivot is connected to the truss mechanism 101 and sleeved on the top of the support mechanism 102, so that the truss mechanism 101 can rotate along the support mechanism 102 via the pivot, and the wall panel can be further installed at any position on the edge of the steel storage tank 200.

[0054] In another preferred embodiment of this utility model, the walking mechanism 103 includes a plurality of wheels connected sequentially by a connecting rod 109, wherein the number of wheels is at least three. A first motor 110 is mounted on the connecting rod 109, and the first motor 110 is used to drive the wheels to move. Further, a chain for connecting the first motor 110 and the wheels is mounted on the first motor 110, and the operation of the first motor 110 drives the chain to move, thereby driving the wheels to move.

[0055] In another preferred embodiment of the present invention, the hoisting mechanism 104 includes: a second motor 111 wound with a steel wire rope, wherein the second motor 111 is used to drive the steel wire rope to move telescopically along the concave groove 105; wherein a hoisting component is connected to one end of the steel wire rope away from the second motor 111.

[0056] It should be noted that the lifting components include a single pulley 112 and a hook 113 that is rotatably connected to the single pulley 112; wherein, the single pulley 112 is connected to a wire rope at the end away from the second motor 111. The second motor 111 drives the single pulley 112 on the wire rope to slide, and the sliding of the single pulley 112 drives the hook 113 connected to it to move, thereby lifting the tank wall panel through the hook 113 and installing it at a designated position on the edge of the steel storage tank 200.

[0057] In another embodiment of this utility model, a method for loading tank wall panels is also provided, which is applied to the tank wall panel loading device 100 described in any of the above embodiments. The method includes: installing the tank wall panel loading device 100 at the center of the top of the steel tank 200; parking a truck crane at a fixed location to lift each wall panel; securing the lifted wall panel to the lifting mechanism 104 of the tank wall panel loading device 100; and using the tank wall panel loading device 100 to move the wall panel to a designated position on the edge of the steel tank 200.

[0058] The present invention provides a method for loading tank wall panels, which addresses the challenges of site limitations or crane cost reduction during the loading process. This method involves the development of a tank wall panel loading device 100, which is safe, reliable, and easy to operate. Its length can be adjusted arbitrarily according to the diameter of the steel tank 200, and it can be used for tank wall panels weighing up to three tons. By adopting this method, the problem of requiring only one crane to feed the tank wall panels at a designated location is solved, eliminating the need for the crane to move around the steel tank 200 for loading, thus shortening loading time and saving crane costs.

[0059] In one embodiment of the utility model, the step of securing the hoisted wall panel to the hoisting mechanism 104 of the tank wall panel loading device 100, and using the tank wall panel loading device 100 to move the wall panel to a designated position on the edge of the steel storage tank 200, includes:

[0060] The first ring of wall panels is hoisted into place one by one, and the verticality, roundness, levelness and welding joint assembly gap of the wall panels are adjusted. The verticality shall not exceed 16mm, the roundness shall not exceed ±21mm, the welding joint assembly gap shall be controlled within the range of 3-5mm, and the misalignment shall not exceed 1.7mm.

[0061] Fixing blocks are used to fix the angle joint between the first ring wall panel and the bottom plate. After the vertical weld of the first ring wall panel is completed, the joint between the first ring wall panel and the bottom plate is welded to control the welding deformation of the bottom plate.

[0062] The second ring of wall panels is hoisted into place, and the verticality, roundness, horizontality, and weld joint assembly gap of the second ring of wall panels are adjusted. The installation accuracy is the same as that of the first ring of wall panels, and the circumferential joints are rigidly fixed.

[0063] Repeat the installation steps for the second ring of wall panels until the installation of the third ring of wall panels is completed;

[0064] The fourth ring wall panel is hoisted into place, and its verticality, roundness and other installation dimensions are adjusted. After positioning, it is rigidly fixed. Then, the vertical weld is completed. After all the fourth ring wall panels are in place, the circumferential joint between the fourth ring wall panel and the third ring wall panel is welded.

[0065] Repeat the installation steps for the fourth ring of wall panels until the fifth ring of wall panels is installed.

[0066] In another embodiment of the utility model, the method for loading the tank wall plate further includes:

[0067] During the installation of the wall panels, while controlling the verticality of each ring of wall panels, it is necessary to ensure that the overall verticality error of the steel storage tank 200 does not exceed 1 / 220 of its height.

[0068] The operation of the storage tank wall panel feeding device and feeding method provided by this utility model is as follows: When the storage tank wall panel needs to be fed, a truck crane can place the wall panel close to the tank body of the steel storage tank 200 at a fixed location, and then workers can use hooks to hang and lift the wall panel to a simple lifting mechanism and move it to a designated location around the steel storage tank 200. The truck crane does not need to move and can directly unload the material from the trailer and feed the wall panel at a fixed location.

[0069] The beneficial effects of the tank wall panel loading device and method provided by this utility model are as follows: the use of the tank wall panel loading device 100 can significantly reduce the movement frequency of the truck crane and reduce the safety hazards caused by the truck crane being unable to deliver the wall panel to the designated position when the wall panel is in place due to site limitations, requiring manual dragging; in addition, the tank wall panel loading device 100 used in this utility model is simple to manufacture, quick to install, and can be used after connecting the power supply after being in place. It has a high reusability, can be adjusted in length at will, is lightweight, and is safe and reliable. After adopting this method for loading tank wall panels, the method addresses the challenges of site limitations or the need to reduce crane costs during the loading process. This method involves the development and in-depth research of a tank wall panel loading device 100. This device is safe, reliable, and easy to operate. Its length can be adjusted arbitrarily according to the diameter of the steel tank 200, and it can be used for tank wall panels weighing up to three tons. By adopting this method, all tank wall panel loading can be accomplished with just one crane at a designated location, eliminating the need for the crane to move around the steel tank 200 for loading, thus shortening loading time and saving crane costs.
