Description

Technical Field

[0002] Large-span steel structures generally refer to those with spans greater than 50 meters. With the rapid development of modern construction technology, large-span steel structures have been widely used in large public buildings such as stadiums, exhibition centers, and airport terminals due to their advantages such as light weight, high strength, fast construction speed, excellent flexibility, and superior seismic performance. However, existing large-span steel structure technology solutions still have some significant shortcomings during the design and construction process.

[0003] For example, due to its large size and weight, large-span steel structures are often constructed in sections in the factory and then assembled and welded on-site. On-site assembly and welding means placing the large-span steel structure sections on the ground one by one, and workers use handheld electric welding to weld them. After welding, cranes, hoists and other equipment are used to turn the large-span steel structure sections over and weld the bottom. Large-span steel structure sections are large in size and heavy, so it is difficult to adjust their position during construction, which not only affects the construction period of subsequent welding, but also has a relatively low safety factor for the hoisting operation to adjust the position.

[0021] In order to enable people skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work should fall within the scope of protection of the present invention.

[0022] At the same time, the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like cited in this specification indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention. Changes or adjustments to their relative relationships, without substantially changing the technical content, should also be regarded as the scope of implementation of the present invention.

[0023] At the same time, in the description of this specification, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be a connection between the internal parts of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0024] Due to their large size and weight, large-span steel structures are often constructed in sections in the factory and then assembled and welded on-site. On-site assembly and welding means placing the large-span steel structure sections on the ground one by one, and workers use handheld electric welding to weld them. After welding, they use cranes, hoists and other equipment to turn the large-span steel structure sections over and weld the bottom. Large-span steel structure sections are large in size and heavy, so it is difficult to adjust their position during construction. This not only affects the construction period of subsequent welding, but also the safety factor of the hoisting operation for adjusting the position is relatively low.

[0025] Therefore, the design concept of this application is to design a device that can support large-span steel structure sections and facilitate their welding. This device can not only support large-span steel structure sections, but also move and rotate large-span steel structure sections, and more easily adjust to the appropriate welding position, so that workers can weld as quickly as possible and avoid affecting the construction period of subsequent welding. Moreover, because the large-span steel structure sections are supported and suspended, there is a distance from the ground. The large-span steel structure sections do not need to be turned over, and workers can weld to the bottom. The safety factor of construction is higher than that of lifting operations.

[0026] like Figure 1 As shown, the present application provides a hydraulic support device for large-span steel structure construction, including a moving platform, on which a lifting mechanism is provided, the lifting mechanism is connected to a rotating mechanism, the rotating mechanism is connected to a support platform 8, and the support platform 8 is provided with a clamping mechanism.

[0027] The mobile platform includes a ground rail 2 , a sliding hydraulic jack 3 is provided on the ground rail 2 , the protruding end of the sliding hydraulic jack 3 is connected to a platform 4 , and the platform 4 is slidably connected to the ground rail 2 .

[0028] During installation, anchor bolts can be used to fix the ground rail 2 on the ground, and the sliding hydraulic jack 3 can be extended and retracted to make the platform 4 slide back and forth on the ground rail 2. The sliding platform 4 can slide back and forth with the various mechanisms on it. The mobile platform can be purchased as a finished product directly, such as the Kainte KET-HT heavy-duty sliding hydraulic system sliding platform with a maximum pushing tonnage of 300T-1000T.

[0029] The lifting mechanism includes a push hydraulic jack 5 installed on a platform 4 , the push hydraulic jack 5 is connected to a connecting plate 6 , and the connecting plate 6 is connected to the rotating mechanism.

[0030] When in use, when the jacking hydraulic jack 5 is raised or lowered, the rotating mechanism will be raised or lowered with it. The jacking hydraulic jack 5 can be purchased as a finished product directly. Several jacking hydraulic jacks 5 can be installed symmetrically to have better bearing capacity.

[0031] The rotating mechanism includes a hydraulic turntable 7 connected to the connecting plate 6 , and the hydraulic turntable 7 is connected to the supporting platform 8 .

[0032] When in use, the hydraulic turntable 7 rotates, which will cause the support platform 8 to rotate. The hydraulic turntable 7 can be purchased as a finished product, such as the Kainte KET-TT hydraulic turntable, which has a maximum rotation load of 300T and can meet 360° steering requirements.

[0033] The clamping mechanism includes a hydraulic jack 9 , and the hydraulic jack 9 is connected to a clamping plate 10 .

[0034] When in use, the hydraulic jack 9 is extended and retracted, and the clamping plate 10 is moved to clamp the large-span steel structure section 1.

[0035] Among them, the two ends of the support platform 8 are respectively provided with a mounting plate I11 and a mounting plate II12, and the mounting plate I11 and the mounting plate II12 are respectively provided with clamping mechanisms, and a clamping space 13 is provided between the clamping mechanism on the mounting plate I11 and the clamping mechanism on the mounting plate II12.

[0036] When in use, the long-span steel structure segment 1 is placed on the clamping space 13 , the hydraulic jacks 9 at both ends are started, and the clamping plates 10 are brought close to the long-span steel structure segment 1 and finally clamped on both sides of the long-span steel structure segment 1 .

[0037] In use of the present application, multiple large-span steel structure segments 1 to be spliced ​​are placed on the hydraulic support device respectively (one large-span steel structure segment 1 corresponds to one hydraulic support device; try to place the middle part of the large-span steel structure segment 1 in the clamping space 13, which is more conducive to stable placement), start the hydraulic jack 9 to clamp the large-span steel structure segment 1, start the pushing hydraulic jack 5 of the lifting mechanism, and raise the multiple large-span steel structure segments 1 to be spliced ​​to matching heights respectively, start the hydraulic turntable 7 of the rotating mechanism, and rotate the multiple large-span steel structure segments 1 to be spliced ​​to matching angles, start the sliding hydraulic jack 3 of the moving platform, and slide horizontally to match the large-span steel structure segment 1 to be spliced. After the position is adjusted, welding can be carried out.
