Description

Technical Field

[0001] The utility model relates to the technical field of feeding platforms, and relates to a steel structure feeding platform. Background Art

[0002] The real estate industry has developed rapidly, driving the economic development of many industries. At present, real estate mainly includes types such as villa residences, ordinary commercial and residential buildings, and apartment residences to meet the housing purchase needs of different home buyers. For people with relatively weak economic capabilities, apartment residences are a more ideal choice.

[0003] Apartment residence projects are often designed in the form of steel structure mezzanines. In actual construction, the installation of mezzanine steel structures is usually carried out after the completion of the civil structure. The vertical transportation of steel structure materials is a key link that must be solved during the installation of steel structures. At present, there are mainly the following two construction methods: One method is to use a crane to lift the steel structure to the working floor and then manually drag it directly into the floor. This method has low construction efficiency and poses a relatively large safety hazard. The other method is to use a crane to lift the steel structure to the working floor and then transport it into the floor through the unloading platform used for civil structure construction. In this way, due to the limitations of the plane size and bearing capacity of the unloading platform used for civil structure construction, the steel structure often needs to be transported in sections, which directly increases the workload of on-site installation of the steel structure and also has a certain impact on the overall mechanical properties of the steel structure.

[0004] In view of the above problems, Chinese Patent with the publication number CN217353628U provides a cantilever platform for steel structure feeding. The cantilever platform includes two support frames, at least two cross braces, two triangular frames, and a rotating shaft; each support frame includes a cantilever main beam extending in the horizontal direction, a first vertical brace arranged vertically, a second vertical brace arranged vertically, a first inclined brace arranged obliquely, and a second inclined brace arranged obliquely.

[0005] Although the above-mentioned cantilever platform can complete the feeding of the steel structure safely and efficiently, when the rotating shaft transmits the steel structure, since the steel structure is not limited, the heavier steel structure is prone to tilt towards the direction of the first vertical brace during the feeding process, resulting in the steel structure hitting the first vertical brace and deforming it. Moreover, after the steel structure tilts to one side, the force on the entire platform will be uneven, which will shorten the service life of the platform. Summary of the Utility Model

[0006] In view of the above technical problems existing in the prior art, a steel structure feeding platform is provided, which solves the problems that due to the lack of limitation on the steel structure, the heavier steel structure is prone to tilt towards the direction of the first vertical brace during the feeding process, resulting in the steel structure hitting the first vertical brace and deforming it, and after the steel structure tilts to one side, the force on the entire platform will be uneven, which will shorten the service life of the platform.

[0007] The object and effect of the present utility model are achieved by the following specific technical means:

[0008] A steel structure loading platform, comprising a cantilever bracket, a support bracket and a vertical bracket. The cantilever bracket is integrally formed at the front end of the support bracket, and the vertical bracket is welded to the upper side of the support bracket;

[0009] Both the cantilever bracket and the support bracket are provided with a plurality of conveying components. The conveying component includes a triangular bracket, a rotating shaft and a limiting member. A pair of triangular brackets are provided and welded to the cantilever bracket or the support bracket. The rotating shaft is rotatably connected between the pair of triangular brackets. Two limiting members are provided and both are installed on the rotating shaft. The heights of the plurality of rotating shafts decrease in equal proportion from outside to inside.

[0010] Optionally, the limiting member includes a limiting sleeve and a pipe clamp. The limiting sleeve is rotatably sleeved on the rotating shaft, and the pipe clamp is clamped on the rotating shaft and is detachably connected to the limiting sleeve.

Specific embodiments

[0023] Please refer to Figures 1-4 for further description of the embodiments of the present utility model;

[0024] A steel structure loading platform includes a cantilever bracket 1, a support bracket 3 and a vertical bracket 6. The cantilever bracket 1 is integrally formed at the front end of the support bracket 3, and a limit bracket 2 is welded to the bottom of the cantilever bracket 1. The vertical bracket 6 is welded to the upper side of the support bracket 3, and a plurality of mounting plates 5 are welded above both sides of the vertical bracket 6;

[0025] This loading platform is used for loading steel structures during construction. Since the height of the vertical bracket 6 can reach the top side beam 8, this loading platform needs to be placed sideways on the floor slab 7 first. When the vertical bracket 6 is inside the top side beam 8, this loading platform is erected. At this time, the support bracket 3 is on the floor slab 7, the cantilever bracket 1 is suspended above the floor slab 7, and the limit bracket 2 just fits against the side of the floor slab 7, which can limit this loading platform. As shown in Figure 1 , a plurality of mounting plates 5 are fixed to the top side beam 8 by using a plurality of bolts, and heavy objects can be used to limit both sides of the support bracket 3 to ensure the stability of this loading platform.

[0026] Both the cantilever bracket 1 and the support bracket 3 are provided with a plurality of conveying components 4. The conveying component 4 includes a tripod 41, a rotating shaft 42 and a limiting part 43. A pair of tripods 41 are provided and welded to the cantilever bracket 1 or the support bracket 3. The rotating shaft 42 is rotatably connected between the pair of tripods 41. Two limiting parts 43 are provided and both are installed on the rotating shaft 42. The heights of a plurality of rotating shafts 42 decrease in equal proportion from outside to inside;

[0027] As shown in Figures 1-2As shown in the figure, during use, the distance between the two limit members 43 is adjusted according to the size of the steel structure, and the two limit members 43 are symmetrically distributed along the central axis of the rotating shaft 42. Then, the steel structure such as the steel beam is hoisted to the feeding platform, and the steel structure is placed on the outermost rotating shaft 42, that is, the highest rotating shaft 42, and the steel structure is placed between the two limit members 43, which can limit both sides of the steel structure, avoid the steel structure from slipping and hitting the vertical frame 6 during feeding, and make the steel structure continuously move in the middle position of several rotating shafts 42, ensuring the stability and safety of the feeding platform during use, extending the service life of the feeding platform, and there is no need to additionally set up a stable structure such as the bottom beam and inclined beam in the patent with the publication number CN217353628U, saving materials and reducing the volume of the feeding platform, which is convenient for handling;

[0028] Since the heights of several rotating shafts 42 decrease in equal proportion from the outside to the inside, the feeding can be completed by relying on the self-weight sliding of the steel structure. When the steel structure slides, it will drive the rotating shaft 42 to rotate on the triangular frame 41, so that the steel structure is transported into the building. The setting of several conveying components 4 is beneficial to the more stable transportation and safer and more reliable operation of the steel structure.

[0029] The limit member 43 includes a limit sleeve 431 and a pipe clamp 435. The limit sleeve 431 is rotatably sleeved on the rotating shaft 42, and the pipe clamp 435 is clamped on the rotating shaft 42 and is detachably connected to the limit sleeve 431;

[0030] Specifically, the pipe clamp 435 and the limit sleeve 431 can adopt detachable connection methods such as snap connection and bolt connection. If it is necessary to adjust the limit member 43, the pipe clamp 435 and the limit sleeve 431 are separated, and then the pipe clamp 435 can be opened. At this time, the positioning of the limit sleeve 431 is released. After that, the limit sleeve 431 can be slid to the required position. After determining the position, move the pipe clamp 435 and make it close to the limit sleeve 431, then clamp the pipe clamp 435 on the rotating shaft 42, and finally install the pipe clamp 435 and the limit sleeve 431 together to reposition the limit sleeve 431 to prevent the limit sleeve 431 from sliding on the rotating shaft 42. The space between the two limit sleeves 431 allows the steel structure to move, and the two limit sleeves 431 play a role in limiting the steel structure, enabling the safe movement of the steel structure.

[0031] A number of corresponding threaded holes 432 are opened on the sides of the limit sleeve 431 and the pipe clamp 435 close to each other. A threaded rod 433 is threadedly connected between the two corresponding threaded holes 432, and a handle 434 is welded on the threaded rod 433;

[0032] The threaded rod 433 is connected to the corresponding two threaded holes 432 so that the limit sleeve 431 and the pipe clamp 435 are fixed together; when it is necessary to separate the pipe clamp 435 from the limit sleeve 431, the operator holds the pipe clamp 435 with one hand, and can pinch and rotate the handle 434 with the other hand, so that the threaded rod 433 can be screwed out from the threaded hole 432 on the pipe clamp 435, thereby releasing the positioning of the pipe clamp 435 and the limit sleeve 431.

[0033] The support frame 3 is in an M shape and encloses two triangles with the cantilever support 1;

[0034] As Figures 1-3 shown, since the support frame 3 is in an M shape, the space occupied by the support frame 3 is small, which is convenient for the operator to move during feeding; the setting that the support frame 3 and the cantilever support 1 enclose two triangles is to enhance the stability and firmness between the support frame 3 and the cantilever support 1.

[0035] The vertical frame 6 is triangular;

[0036] The setting that the vertical frame 6 is triangular is also to enhance the firmness of the vertical frame 6, and this design uses less material.
