Definitions
- the invention relates to a step for an escalator, with a made of sheet metal staged skeleton as a support for at least one tread element and at least one setting element, wherein the setting element has a made of a deep-drawn sheet web / groove profile with webs and grooves and each web of seen the setter base has a cavity and the setting element is arcuate.
- the step includes a tread element having a plurality of horizontally extending ledges and a seating member having a plurality of vertically extending ledges.
- the strips of the tread element mesh with the strips of the setting element of the adjacent step, the gap width being dependent on the relative position of the adjacent steps.
- a step performs relative to the adjacent steps in the vertical direction from a relative movement, especially in the transition from the inclined escalator section to the horizontal escalator section.
- the step structure of the escalator is thereby converted into a planar structure or band structure.
- the height difference between two adjacent stages continuously changes from the maximum value to zero.
- the relative movement is generated by a corresponding course of the guideways for the step rollers and chain rollers.
- the step has - cut in the direction of travel - about a triangular cross-section.
- the setting element is not flat, but as Cylinder wall section, so in cross section circular arc, so that the step cut in the direction of travel has the shape of a circular sector rather than a triangle.
- the gap between two stages is not constant, but changes depending on how large the height difference between two adjacent stages is.
- the step is centrally loaded with a force acting perpendicular to the tread element of 3000 N, with a deflection of at most 4 mm may occur. After the force has been applied, the step must not show any permanent deformation.
- the stage is centered with a pulsating force, with the force varying between 500 N and 3000 N, with a frequency between 5 Hz and 20 Hz and at least 5x10 6 cycles. After the test, the step may have a permanent deformation of not more than 4 mm.
- Unwinding held and unwindable sheet metal roll for example, 2 m to 4 m in diameter, hereafter called sheet metal coil, can be produced optimized production. With multiple unwinding devices, the workflow can be made interruption-free and production time can be further reduced.
- a step with skeletal or frame-like sheet metal construction is easier and much cheaper than a die-cast aluminum, especially with increasing aluminum price.
- a 600 mm wide stage weighs about 8.6 kg
- a 800 mm wide stage weighs about 10.8 kg
- a 1000 mm wide stage weighs about 13.1 kg.
- the step width or the retrofitting process require no expensive additional work in small quantities.
- Optimized to minimum weight and maximum load according to the above-mentioned standard EN 115 level is feasible with thin thermoforming sheets, for example, 1, 1 to 1, 9 mm thickness, the maximum stiffening of the allow supporting components. Embossing or bending process would also be conceivable, but the finished stage would be much heavier, because in this manufacturing process larger sheet thicknesses (at least 4 mm sheet thickness) are necessary.
- the setting made of thin, for example, 0.25 to 1, 25 mm thickness to 10 to 15 mm deep-drawn deep-drawn sheet has its web / groove profile sufficient rigidity at extreme loads. Despite increased rigidity, the weight of the tread element remains small.
- the setting element weighs at a plate thickness of 0.4 mm
- the strength of the setting element depends on the material.
- the elastic limit is 380 to 480 N / mm 2 . Then the material comes in the plastic area.
- the breaking point is 440 to 580 N / mm 2 .
- the elastic limit is 400 to 520 N / mm 2 . Then the material comes in the plastic area.
- the breaking point is 470 to 590 N / mm 2 .
- the elastic limit is 790 N / mm 2 . Then the material comes in the plastic area.
- the breaking point is 900 N / mm 2 .
- the elastic limit is 1020 N / mm 2 . Then the material comes in the plastic area.
- the breaking point is 1100 N / mm 2 .
- the setting element according to the invention can also be used in stages that have bridge-like instead of the middle cheeks, connecting the side cheeks cross member.
- thermoforming sheet When deep-drawing a punch presses a sheet metal blank in a prefabricated die, wherein the edge of the sheet metal blank is held by means of a hold-down.
- a temporary plastification and strain hardening takes place below the hold-down the thermoforming sheet.
- the soil can be formed in further process steps, for example by means of hydraulic depths in the stamp or in the die. In the embodiment set out below, the cheeks eyes are made.
- the edge of the walls is separated by trimming, for example by means of knife, punch, water jet or laser.
- the deep-drawn sheet has to be specially created for the forming.
- a deep-drawn sheet with the designation H380 or H400 is used.
- These steel grades are based essentially on the strength-increasing effect of micro-alloying additives such as niobium and / or titanium and / or manganese. The yield strengths of these steels, which are high compared to mild steels, allow for cold forming with low deformation stress up to very demanding and complex component formations.
- the steel grades are adapted to the respective forming conditions, so that even with low sheet thicknesses the tendency to deformation-related constrictions, wrinkles, tearing or inaccurate shape due to elastic recoil is minimal.
- the deep drawing process is characterized by a large ratio of the sheet thickness to the height of the deep-drawn wall and the associated high load capacity, dimensional accuracy and stability.
