Integral type escalator supporting frame

Abstract

The invention discloses an integral type escalator supporting frame which comprises a left lateral plate, an intermediate connector and a right lateral plate. The left lateral plate and the right lateral plate are fixedly connected with each other through the intermediate connector; the left lateral plate and the right lateral plate respectively comprise an upper supporting section, an intermediate supporting section and a lower supporting section; the upper supporting section and the lower supporting section are fixedly connected with the intermediate supporting section; the upper supporting section, the intermediate supporting section and the lower supporting section respectively comprise two face plates which are fixedly connected with each other; and cross type strengthening ribbed plates are fixedly arranged on the inner sides of the face plates. The integral type escalator supporting frame has the advantages of being simple, novel and unique in structure; being uniform in stress distribution, effectively reducing the deformation degree and meeting the requirements for stiffness and stability of the escalator supporting frame; being adaptable to working conditions of severe environment with strong corrosion property; being convenient to assemble and capable of being assembled in site; increasing the single transporting volume and reducing the transportation cost.

Description

technical field [0001] The invention relates to an integral escalator support frame. Background technique [0002] At present, in the technical field of existing escalators, the key supporting parts of the escalator generally adopt truss structures made of steel such as square tubes, I-beams and angle steels. A number of vertical bars and diagonal web bars in the middle form the basic steel beam structure. The traditional truss structure disperses the stress to each truss point. Traditional trusses often use traditional welding or riveting techniques, which makes the process more demanding. Only when the stress value of each truss point is within its stress range. Considering aging and anti-corrosion, the steel surface of the traditional truss structure needs to be painted and regularly maintained, resulting in increased production and maintenance costs, so it is generally not suitable for working conditions in harsh environments with strong corrosiveness; It uses a la...

Problems solved by technology

Considering aging and anti-corrosion, the steel surface of the traditional truss structure needs to be painted and regularly maintained, resulting in increased production and maintenance costs, so it is generally not suitable for working conditions in harsh environments with strong corrosiveness; It uses a large number of traditional techniques such as welding or riveting, the production and assembly process is complex, not suitable for machine production, resulting in increased labor costs, decreased labor productivity, and the thermal deformation process of the welding process is very complicated, making it difficult to correct the deformation of the truss; After the escalator supporting parts of the traditional truss structure are produced, they must be transported to the escalator assembly factory as a whole. Usually, only two trusses can be loaded in one vehicle, so the transportation cost is very high
