In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1 to 3, fig. 1 is a schematic view illustrating an assembly of a platform supporting structure and a frame according to an embodiment of the present invention; FIG. 2 is a schematic structural view of a platform support structure according to an embodiment of the present invention in a first direction; fig. 3 is a structural schematic view of a platform supporting structure provided in an embodiment of the present invention in a second direction.
The present invention provides a platform support structure comprising a support frame 1 and a plurality of platform plates 2.
The support frame 1 is fixedly connected with the rack 01 through a plurality of support members extending downwards, and all the support members are in point-shaped discrete distribution relative to the plane of the support frame 1, so that the number and the range of connection points of the rack 01 and the support members are reduced, and the drilling and connection burden of the rack 01 is relieved. Braced frame 1 is frame-type body structure for supply a plurality of landing slabs 2 to splice in inside, thereby realize a plurality of landing slabs 2 and 01 relatively fixed of frame.
The material of the support member can be flexibly selected from carbon steel, aluminum alloy, stainless steel and other metal materials according to different environments, and Q235B or Q355D is mostly adopted. A plurality of support members are connected between one platform plate 2 and the frame 01, and all the support members are discretely arranged in a dot shape between the lower surface of the platform plate 2 and the frame 01. The support members include, but are not limited to, equiaxed connecting members such as bolts and bent, tailor-welded rod-like metal profiles according to the relative positional relationship between the platform plate 2 and the frame 01 to which the support members are connected.
The platform plate 2 is plate-shaped and is used for supporting workers and related working equipment, and also can be used for supporting mechanical parts with small volume and mass. The platform plate 2 may be a Q235 steel plate or an aluminum alloy steel plate having a pattern such as a lenticular pattern. Wherein, the decorative pattern plays antiskid effect, can improve the staff's of standing on the landing slab 2 security.
When a plurality of landing slabs 2 are assembled in the inside of the supporting frame 1, the supporting frame 1 can be fixedly connected with the supporting frame 1 and any one of the landing slabs 2 through the modes of erection, fastener locking, welding and the like.
When the platform support framework provided by the invention is applied to actual operation, the number and relative positions of the platform plates 2 installed in the support frame 1 depend on the requirements of specific operation. For example, when a worker only needs to move or set up related work equipment in a partial standing state above the machine frame 01, a part of the deck boards 2 may be installed in the support frame 1, and the entire deck boards 2 need not be installed. When the working area of the worker above the rack 01 covers the entire area where the rack 01 is located, all the platform boards 2 are installed in the support frame 1.
The peripheral side of any platform plate 2 adjacent to the rack 01 is spliced on the top surface of the rack 01, and in brief, the rack 01 is matched with the adjacent platform plate 2 in shape. The specific geometry of the platform plate 2 depends on the shape of the top surface of the frame 01. Therefore, the platform supporting structure provided by the invention not only supports workers and related operation equipment by the platform plate 2, but also has a supporting effect by combining with the top surface of the rack 01.
With reference to fig. 1, the upper surface of the frame 01 may not be continuous and complete planar structure, and for this reason, the platform board 2 may be set to a special geometric shape, including but not limited to the rectangle and L shape shown in fig. 1, which is matched with the upper surface of the frame 01 according to the specific shape of the upper surface of the frame 01, so that the platform board 2 may be used as an operation platform by erecting a flat and continuous planar structure on the basis of the upper surface of the frame 01.
In summary, the platform supporting structure is uniformly and regularly connected with the rack 01 through the supporting frame 1 having a frame-type integrated structure, and the supporting frame 1 is used as a supporting part of one or more platform boards 2 fixedly connected with the rack 01. On one hand, the platform supporting structure is fixedly connected with the rack 01 through the supporting frame 1 and the plurality of supporting pieces which are connected with the supporting frame and are in point-like discrete distribution, so that the platform plate 2 is installed on the rack 01 in a standard and uniform manner, scattered platform parts and supporting parts are integrated, standardization is realized, and the transportation, storage and assembly costs are reduced; the number of holes drilled on the frame 01 is reduced, the processing cost is reduced, the workshop assembly efficiency is improved, and the load reduction of the frame 01 is realized. On the other hand, the platform plate 2 is used to splice the top surface of the frame 01, so that the frame 01 and the platform plate 2 can share the supporting task, thereby reducing the number and the quality of the platform parts and the related supporting parts.
The platform support structure provided by the present invention will be further described with reference to the accompanying drawings and embodiments.

Referring to fig. 2 and 3, the supporting frame 1 is formed by splicing and fixing a plurality of laterally distributed supporting plates and a plurality of longitudinally distributed supporting plates, and the distance between any two adjacent and laterally distributed supporting plates is smaller than the longitudinal distance between one platform plate 2, and similarly, the distance between any two adjacent and longitudinally distributed supporting plates is smaller than the transverse distance between one platform plate 2. It should be noted that the transverse direction and the longitudinal direction are based on the directions in the horizontal plane.
In this embodiment, because the size of arbitrary landing slab 2 is greater than the interval of adjacent backup pad, consequently, when landing slab 2 splices in this braced frame 1, landing slab 2 erects in the upper end of backup pad to utilize the backup pad to improve the structural strength and the rigidity of landing slab 2.
The support frame 1 may be a metal frame to ensure the connection strength and stability of the platform board 2 and the frame 01. The metal frame can be formed by bending, welding or bolting a round steel, a square steel, an angle steel, a channel steel, an L-shaped steel, an H-shaped steel and other profiles, for example, a plurality of Q355 angle steels.

It can be seen that the diagonal support beams can form a reliable support for the support frame 1 and the platform plate 2 above the top surface of the frame 01 by using a partial structure below the top surface of the frame 01.
The present invention provides a platform support structure in which the number of the support beams 5 connected to one support frame 1 is not more than two, based on the structural characteristics of the support beams 5 themselves and the installation relationship of the support beams 5 between the support frame 1 and the frame 01.
The platform support structure provided by the present invention further comprises a cable gallery bridge 3.
The cable bridge 3 is fixed to the support frame 1, typically at the edge of the support frame 1, for positioning the control cables for mounting the electrical equipment. The cable gallery bridge 3 can be formed by bending Q235 round steel and welded on the edge of the supporting frame 1.
The structure of the cable bridge 3 can be referred to the related structure in the prior art, and can be fixed to the support frame 1 by welding or fastener connection.
In the embodiment, the control cables of most of electrical equipment can be bound and fixed on the supporting frame 1 through the cable gallery bridge 3, a cable bridge is not required to be installed on one side of the rack 01 or above the rack 01, the load of the rack 01 is further reduced, the assembly efficiency is improved, and the attractive and standardized cable layout can be realized.
