[0001] This utility model belongs to the field of temporary support, and in particular relates to a modular temporary support device. Background Technology

[0002] When installing large rolling mill arches using the sliding method, the arches often weigh up to 400 tons, requiring temporary supports for the gantry crane's travel area, especially the top plate area of ​​the underground hydraulic station, to ensure the crane can pass safely and smoothly. Currently, on construction sites, traditional temporary supports are created by cutting steel pipes or H-beams and welding them together, then using chain hoists to stand the pipes or H-beams upright. This method has the following drawbacks:

[0003] 1) It is time-consuming and labor-intensive. The slow progress of the temporary support device construction directly restricts the hoisting progress of the large rolling mill stand.

[0004] 2) It is very difficult to erect steel pipes or H-beams in a confined space. It is necessary to fix support points at certain locations and then use the support points to pull the steel pipes or H-beams up at an angle and erect them until they are tightly pressed against the top plate. The construction is very difficult.

[0005] 3) The dismantled supports are difficult to reuse, which wastes materials and increases costs. Utility Model Content

[0030] The embodiments of this utility model will now be described with reference to the accompanying drawings.

[0031] like Figure 1 As shown, this utility model proposes a modular temporary support device, including a temporary support 20 and a lifting device 10; the temporary support 20 includes a plurality of support modules 21, which are detachably aligned and connected to each other; the lifting device 10 surrounds the temporary support 20 and is provided with a hoisting mechanism 16 and a movable bracket 13. The hoisting mechanism 16 is used to lift the support modules 21 or a combined module formed by combining a plurality of the support modules 21 within the height range of the lifting device 10, and place it on the movable bracket 13, thereby realizing the installation of the temporary support 20 from top to bottom in a limited space.

[0032] Specifically, the aforementioned support modules 21 are prefabricated in the factory. During use, several support modules 21 are aligned and connected according to the required support height to form a temporary support 20. In use, the lifting device 10 lifts the support module 21 and places it on the movable bracket 13. Then, the next support module 21 is lifted and aligned with the support module 21 located on or on the movable bracket 13 to form a combined module. This combined module is then lifted, and the lower support module 21 is placed on the movable bracket 13. This process is repeated until the entire temporary support 20 is installed. The overall installation process is simpler and more efficient; the top-down installation method occupies less space and is suitable for confined spaces; the combination of support modules 21 allows for different support height requirements, providing greater flexibility; and the alignment connection between the support modules 21 facilitates installation and disassembly, promotes reuse, reduces material waste, and saves construction costs.

[0033] Furthermore, the lifting device 10 also includes a column 12, with a rotating shaft 14 at the center of the column 12. One end of the movable bracket 13 is connected to the rotating shaft 14 and can rotate around the rotating shaft 14 to be perpendicular to the column 12. In use, several lifting devices 10 are arranged around the perimeter, forming an area where the temporary support 20 is to be installed. One end of the movable bracket 13 is hinged to the column 12. In use, the movable bracket 13 is rotated so that its other end extends into the area enclosed by the lifting devices 10. Through cooperation with the hoisting mechanism 16, the support module 21 is lifted and temporarily placed.

[0034] Specifically, when the hoisting mechanism 16 performs the lifting operation, the movable bracket 13 is retracted so that the area enclosed by the lifting device 10 is large enough to accommodate the support module 21. When the hoisting mechanism 16 lifts the support module 21 to a certain height, the movable bracket 13 is lowered so that it is perpendicular to the column 12, and the support module 21 is placed on the movable bracket 13 by the hoisting mechanism 16. After the hoisting mechanism 16 lifts the next support module 21 and aligns it with the support module 21 on the movable bracket 13, the movable bracket 13 is opened. At this time, the overall weight of the combined module formed by the two support modules 21 is borne by the hoisting mechanism 16. The hoisting mechanism 16 continues to lift the combined module to a certain height, lowers the movable bracket 13, and temporarily places the combined module on the movable bracket 13.

[0035] Furthermore, this application also proposes a specific structure in which the movable bracket 13 is hinged to the column 12: as follows Figure 2 As shown, the rotating shaft 14 is mounted on one side of the column 12 via a mounting base, and is arranged horizontally. A limiting slot 15 is provided at the corresponding part of the column 12 and the rotating shaft 14. The movable bracket 13 is a plate-like structure, and its width is not greater than the corresponding width of the limiting slot 15. The middle part of the movable bracket 13 is movably connected to the rotating shaft 14, allowing it to rotate around the rotating shaft 14. When the movable bracket 13 rotates to be perpendicular to the column 12, one end extends into the limiting slot 15, and its upper end face abuts against the upper inner wall of the limiting slot 15, thus engaging with the limiting slot 15 and allowing the movable bracket to... The movable support leg 13 can only rotate upwards and cannot continue to rotate downwards, thus enabling the retraction and lowering of the movable support leg 13. Preferably, a torsion spring is provided between the rotating shaft 14 and the movable support leg 13. The two straight segments of the torsion spring are fixed to the rotating shaft 14 and the movable support leg 13, respectively. When the movable support leg 13 is lowered, the torsion spring is in a torsional state and is perpendicular to the column 12 under the load pressure of the support module 21. When the hoisting mechanism 16 continues to lift upwards, the pressure on the movable support leg 13 disappears, and the torsion spring drives the movable support leg 13 to automatically reset, providing sufficient space for the lifting of the support module 21. The torsion spring is a commercially available product, and its specific structure will not be described in detail here.

[0036] Furthermore, such as Figure 3As shown, this application proposes a structure for a lifting device 10, including a base 11, a column 12, a hoisting mechanism 16, and a movable bracket 13. The base 11 is located at the bottom of the column 12, stably fixing the column 12 to a predetermined position on the ground to prevent it from tipping over. The hoisting mechanism 16 is located at the top of the column 12, including a chain hoist 162 and a drive device 161. One end of the chain hoist 162 is provided with a hook for connecting the object to be hoisted. The drive device 161 can extend or shorten the chain hoist 162 to lift the object. The movable bracket 13 is located in the middle of the column 12. Meanwhile, the support module 21 is provided with a lifting lug that cooperates with the hook.

[0037] The main function of the aforementioned support module 21 is to form a temporary support 20 through alignment and connection, bearing the pressure load transmitted by the upper support structure. Therefore, its specific shape and structure can be set according to requirements, as long as the bearing capacity requirements are met. In this embodiment, the support module 21 is formed by connecting several rod-shaped, strip-shaped, or plate-shaped components into a whole, with the overall shape being square. Lifting lugs are set in the middle of the vertical components at the four corners of the support module 21. Correspondingly, there are four lifting devices 10, which are respectively set at the positions of the lifting lugs, forming a square area that can accommodate the support module 21, so as to facilitate the lifting of the support module 21. In some other embodiments of this application, the support module 21 can also be of other shapes, and the lifting devices 10 are set to correspond to the specific shape of the support module 21. Preferably, the support module 21 is made of commonly used construction materials, with a simple structure and easy manufacturing.

[0038] Furthermore, the support module 21 includes a top module 22, a standard module 23, and a bottom module 24, which are aligned and connected via connecting flanges 25. The connecting flanges 25 are respectively located at the bottom of the top module 22, the top and bottom of the standard module 23, and the top of the bottom module 24. The top module 22, standard module 23, and bottom module 24 are aligned and connected from top to bottom to form a temporary support 20. The top module 22 is located at the top of the temporary support 20, the bottom module 24 is located at the bottom of the temporary support 20, and the standard module 23 is located between the top module 22 and the bottom module 24. The number of standard modules 23 can be selectively set according to the required support height.

[0039] like Figure 4 As shown, the connecting flange 25 is a plate-shaped structure with threaded holes. After the upper and lower support modules 21 are aligned, the connecting flange 25 fits together, and the threaded holes form a through hole. Preferably, the through hole is located on the outer side of the outer edge of the support module 21, which facilitates the use of fasteners to pass through the through hole and then locking with bolts to achieve the alignment and connection of the two support modules 21. The number of connecting flanges 25 is not limited here. Preferably, there are two or more connecting flanges 25 to make the connection of the support modules 21 more stable.

[0040] Furthermore, since both the top module 22 and the standard module 23 need to be temporarily placed on the movable bracket 13 during the installation process, the bottom of both the top module 22 and the standard module 23 is provided with a connector 26 that protrudes circumferentially to overlap with the movable bracket 13.

[0041] Preferably, such as Figure 4 As shown, the connecting flanges 25 are located at the bottom four corners of the top module 22 and the top and bottom four corners of the standard module 23. The connecting flanges 25 located at the bottom of both extend outward to a sufficient length so that they can simultaneously connect the upper and lower support modules 21 and overlap with the movable brackets 13, making the structure of the support module 21 more simplified and easier to manufacture.

[0042] Furthermore, the bottom of the bottom module 24 is also provided with adjustable feet 40 for adjusting the height of the temporary support 20. When the temporary support 20 can fully contact the upper structure it supports, it forms effective support. Specifically, the adjustable feet 40 can take the form of studs and supports threadedly connected to the studs, or hydraulic jacks, etc., without limitation.

[0043] Furthermore, the top of the top module 22 is also provided with an adjustable pad 30 for supporting the upper support structure. In a specific embodiment, the support module 21 is factory-customized and has fixed specifications; when the support height requirement cannot be met by combining the support modules 21 and adjusting the adjustable legs 40, the adjustable pad 30 is used to make the temporary support 20 press against the upper structure.

[0044] This application also proposes a method for installing a modular temporary support device, used for installing the modular temporary support device as described above, such as... Figure 5 As shown, it includes the following steps:

[0045] (1) Install the lifting device 10 at the set position and connect and fix it to each other;

[0046] By connecting the lifting devices 10 into one unit, the stability of the lifting devices 10 can be improved, and the safety of their use can be enhanced. The specific connection method is not limited here, such as using connecting rods to connect the columns 12 of two adjacent lifting devices 10 respectively.

[0047] (2) Connect the hoisting mechanism 16 to the top module 22, lift the top module 22, and place it on the movable bracket 13;

[0048] Specifically, the hook of the chain hoist 162 is connected to the lug of the top module 22, and the drive device 161 is operated synchronously to make the top module 22 smoothly raised to a height higher than the movable bracket 13. Then the movable bracket 13 is opened, and the top drive device 161 places the top module 22 on the movable bracket 13.

[0049] (3) Lift a standard module 23, align the standard module 23 with the top module 22 to form a combined module; lift the combined module and place it on the movable cow leg 13;

[0050] Specifically, a standard module 23 is placed below the top module 22. The chain hoist 162 is removed from the top module 22 and connected to the lifting lug of the standard module 23. The drive device 161 is run synchronously to smoothly lift the standard module 23 to the lower part of the top module 22. The connecting flange 25 at the bottom of the top module 22 and the top of the standard module 23 is connected by bolts to align and connect them into a whole to form a combined module. The drive device 161 continues to run. At this time, the connecting flange 25 at the bottom of the top module 22 disengages from the movable bracket 13, and the movable bracket 13 automatically resets. After the combination is lifted to a height higher than the movable bracket 13, the bracket is lowered again so that the connecting flange 25 at the bottom of the standard module 23 overlaps with the movable bracket 13.

[0051] In one specific embodiment, multiple standard modules 23 need to be set according to the support height requirements. The installation of all standard modules 23 can be completed by repeating the method in this step.

[0052] (4) Lift the bottom module 24 and align the bottom module 24 with the standard module 23;

[0053] Specifically, the bottom module 24 is placed below the standard module 23, the chain hoist 162 is removed from the standard module 23 and connected to the lifting lug of the bottom module 24, and the drive device 161 is run synchronously to make the bottom module 24 smoothly lifted to the lower part of the standard module 23. The connecting flange 25 of the bottom of the standard module 23 and the top of the bottom module 24 is connected by bolts to make the two aligned and connected as one, thus completing the alignment and connection of the temporary support 20.

[0054] (5) Install the adjustable support leg 40 on the bottom module 24 and lower the adjustable support leg 40 to the ground;

[0055] Specifically, after the adjustable support leg 40 is installed, the drive device 161 is first run to lift the temporary support 20, so that the standard module 23 located above the bottom module 24 is disengaged from the movable bracket 13, so that the movable bracket 13 can be retracted; then the drive device 161 is run to lower the temporary support 20 to the ground, and the height of the adjustable support leg 40 is adjusted so that the top module 22 abuts against the upper support structure.

[0056] In one specific embodiment, the support height is measured before installation, and the number of standard modules 23 to be installed is calculated based on the support height. When the support height does not match the height of the temporary support 20 after alignment and connection, and the adjustable feet 40 cannot meet the requirements, an adjustable pad 30 is set on the top of the top module 22 before the top module 22 is installed. Then, the top module 22 and the adjustable pad 30 are raised synchronously to ensure that after all the temporary supports 20 are installed, the adjustable feet 40 can be adjusted to make them hit the upper structure.

[0057] This application also proposes a method for dismantling a modular temporary support device, which includes the following steps:

[0058] (1) Connect the hoisting mechanism 16 to the bottom module 24. At this time, the weight of the temporary support 20 is borne by the hoisting mechanism 16; then remove the adjustable support leg 40.

[0059] (2) Lower the temporary support 20 to the ground and disconnect the connection between the bottom module 24 and the standard module 23 above it; lift the combined module and remove the bottom module 24.

[0060] Preferably, since the bottom module 24 has a certain weight, in order to facilitate its movement, after the adjustable bracket is removed, a moving mechanism is set below the temporary support 20. The temporary mechanism is placed on the moving mechanism by the hoisting mechanism 16, so that the removed bottom module 24 is directly placed on the moving mechanism, making its movement more convenient.

[0061] In one specific embodiment, in order to improve the safety of the dismantling operation, after disconnecting the bottom module 24 from the upper combined module, the combined module is temporarily placed on the movable bracket 13.

[0062] (3) Repeat the previous step to remove the standard module 23, lower the top module 22 to the ground, and remove the top module 22;

[0063] (4) Remove lifting device 10.

[0064] This application achieves top-down installation and bottom-up removal of temporary supports in a limited space by setting up temporary supports and lifting devices, occupying less area and making it suitable for narrow spaces; the overall installation and dismantling process is simpler and more efficient; the support modules are prefabricated in the factory, and the combination of support modules can be adapted to different support height requirements, making it more flexible; at the same time, the support modules are connected by alignment, which is easy to install and dismantle, facilitates reuse, reduces material waste, and saves construction costs.

All equivalent changes and improvements made in accordance with the claims of this utility model should still fall within the patent coverage of this utility model.
