Definitions
- the invention relates to a step for an escalator or a pallet for a moving walkway comprising a step skeleton or pallet skeleton as a support for at least one tread element according to the definition of the independent claim.
- the step is skeleton-like and consists essentially of an angled support plate, which forms the side parts and the front part. Arranged on the support plate is an angle at which the wheels of the step are attached. An angled footboard is frictionally connected to the side panels and serves as a step completion upwards. The front part of the step is completed by means of a front panel connected to the support plate.
- the invention seeks to remedy this situation.
- the invention as characterized in claim 1, solves the problem of creating a sheet metal made, lightweight stage or pallet with high rigidity.
- 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 steps structure of the escalator is transferred to a level or band structure.
- the relative movement is generated by a corresponding course of the guideways for the step rollers.
- the step in the direction of travel has approximately a triangular cross-section.
- a pallet does not perform any relative movement in the vertical direction relative to the adjacent pallets.
- the moving pavement consisting of pallets does not change its surface structure when the direction changes, a stepless belt structure as transport surface is always available.
- a pallet is constructed comparable to a step and has cut in the direction of travel about a rectangular cross section without visible setting element.
- An escalator has at least one stage according to the invention, the remaining stages being, for example, conventional aluminum stages or sheet metal stages.
- the remaining stages being, for example, conventional aluminum stages or sheet metal stages.
- the advantages achieved by the invention are essentially to be seen in the fact that weight savings and cost savings are feasible with the skeleton-type sheet metal construction of the stage. Lighter steps also mean smaller drive power for the escalator drive.
- the main components of the stages such as For example, step cheeks, tread element and setting element are made by means of a deep-drawing process of thin deep-drawn sheet metal.
- the stage according to the invention meets the requirements and load tests of the European standard EN 115 and the American standard ASME A17.1, according to which the stage according to the invention must satisfy a static test and a dynamic test.
- 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.
- the inventive step with skeletal 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.
- An optimized to minimum weight and maximum load according to the above-mentioned EN 115 level is feasible with thin thermoforming sheets, for example 1, 1 to 1, 9 mm thickness, which allow by means of deep drawing process, a maximum stiffening of the supporting components. Embossing or bending processes 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 step skeleton or pallet skeleton are made as sheet metal parts, i. are formed from flat elements.
- the cheeks have a cheek body and along the edges of the cheek body on a circumferential, wall-like stiffening. This stiffening achieves an incredibly high stability despite thin (and thus light) metal sheets.
- Such cheeks can be advantageously prepared by a deep drawing process.
- a punch presses a flat 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 plasticization and work-hardening of the deep-drawn sheet occurs below the hold-down.
- the wall thickness is slightly smaller than the original sheet thickness.
- 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 deep-drawn sheet has to be specially created for the forming.
- a deep-drawn sheet with the designation H380 or H400 or H900 or H1100 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 types of steel are tuned to the respective forming conditions, so that even with low sheet thicknesses the tendency to deformation-related constrictions, wrinkles, tearing or inaccurate shape by elastic springback 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.
