Definitions
- the invention relates to a substructure element for a passenger conveyor belt, a method for the production thereof, a conveyor belt substructure for a passenger conveyor belt, a passenger conveyor belt and its use for transporting persons.
- Conveyor belts are often used today to transport people.
- problems due to frost, icing, snow and dirt which is why a majority of passenger conveyor belts currently has an additional roof.
- thermal loads ie for expansion or for working of the material under the influence of temperature.
- skiers and passengers with sports and / or leisure equipment or when transporting passengers in a ski area - additional precautions must be taken to ensure their safety compared to the transport of objects or material.
- Conventionally well-known ski conveyors are often permanently installed although they are not used out of season.
- ski conveyor belts disturb the landscape outside of the season and thus have a detrimental effect on tourism.
- For the seasonal operation of such a conveyor belt is therefore an easy to transport, easy to build and adaptable to the local conditions design desirable.
- a substructure according to claim 1 a conveyor belt substructure according to claim 10
- a passenger conveyor belt according to claim 1 1 and its use according to claim 13 and a method for producing a substructure element according to claim 14.
- the aforementioned sub-element for a passenger conveyor belt has a grid with a plurality of struts, wherein the grid has at least one sliding area and at least one Rau Scheme.
- the substructure element is thus a conveyor belt carrier element, ie it is a - preferably modular usable - element which is a component of the supporting structure of the passenger conveyor belt.
- the grating consists of several intersecting struts.
- the struts may intersect, for example, in a diamond pattern, but preferably they intersect orthogonally.
- the longitudinal struts preferably extend in a longitudinal direction, ie in a direction with the largest dimension of the substructure element.
- the longitudinal direction is also referred to below as the conveyor direction, since it identifies the transport direction of the persons to be transported.
- the transverse struts then extend transversely, preferably vertically, to the longitudinal struts, so that an orthogonal grid results.
- the grate has an upper side and an opposite lower side.
- the persons are transported over the flat top during operation.
- the underside has in operation to a substrate on which the base element is placed.
- the grating thus extends substantially horizontally.
- “essentially” means that the grate has a smaller extent in the vertical direction than in the horizontal directions and is aligned substantially parallel to the ground, but in principle it is also possible, for example, by means of suitable supports to arrange the substructure diagonally in relation to the ground
- the designations "bottom” and “top” or “horizontal” and “vertical” also refer in the following to a substructure element set up for normal operation.
- the design as a grid is advantageous because any precipitation in the form of rain or snow can fall through the gaps or holes of the grid to the ground. As a result, an otherwise often necessary exemption of the sub-element of precipitation residues can be largely avoided. Also dirt deposits fall through the grating and thus the Rau Schl remains clean and non-slip.
- the grating preferably has on its upper side the Rau Schl and the sliding area. In principle, any number and arrangement of both Rau Schlen and sliding areas is possible.
- the Rau Schle and the sliding portions extend side by side, parallel and in the conveying direction in a plane of the top of the grating.
- the Rauwitz is characterized by an example rough surface structure, which increases a frictional resistance of the surface and thus reduces the risk of slipping.
- the sliding region has, for example, a lubricious, preferably smooth, surface structure with a lower frictional resistance in relation to the predatory region, ie. H. relatively high lubricity of the surface.
- the sliding area serves as a support for a conveyor belt, as will be explained in more detail later on the basis of the passenger conveyor belt already mentioned at the beginning.
- the design of the sliding region as a grate is particularly advantageous because, on the one hand, the frictional resistance for the conveyor belt is reduced by the small contact surface and, on the other hand, by the slidable structure.
- the Rau Brown used in the operation as walkway for people who is required and desired for safety reasons and on which the people can move on their own and at low risk of slipping. Also, the Rau Quarry can by means of an additional cover such. Flies, brush strips or the like are equipped to make the walking area more comfortable.
- the struts preferably have an upright, rectangular cross-section. Thereby, a good distribution of the optionally acting on the grid loads and a good deflection stiffness can be achieved, at the same time the surface is advantageously kept small.
- the Rau Schemee and / or the smooth areas can be formed by the modification of the surface of a, preferably commercially available, grate, as will be explained later with reference to the manufacturing process.
- the conveyor belt substructure mentioned at the beginning ie the carrier framework, comprises a number of substructure elements according to the invention.
- an overall length of the conveyor belt substructure can be adapted as required.
- the substructure elements are for this purpose preferably in a row or a chain forming in Longitudinal direction, ie arranged in the conveying direction, and connected to each other to the conveyor belt substructure.
- the conveyor belt substructure overall designates the load-bearing structure of the passenger conveyor belt.
- the passenger conveyor belt mentioned above comprises a conveyor belt substructure according to the invention and a conveyor belt which rests at least in part on the upper side on the sliding areas of the substructure elements.
- the term “passenger conveyor belt” refers to the entire apparatus for transporting persons, but in common usage, the term “conveyor belt” is often used solely for a mobile, load carrying component of the apparatus. This component is referred to herein as a conveyor belt. It surrounds or at least circumscribes at least part of, preferably all, gratings of the substructure elements connected to the conveyor belt substructure.
- the frictional resistance between the conveyor belt and the support surface is advantageously reduced by the support of the conveyor belt in the sliding regions.
- the advantageously low frictional resistance is achieved by the inventive cooperation of reduced contact area by means of the design as a grid and by the lubricious surface in this area.
- further grate bars can be arranged in front of and / or behind the passenger conveyor belt and connected to the conveyor belt substructure, so that, for example, an entry area or an exit area for the passenger conveyor belt is created.
- the passenger conveyor preferably also includes a drive, so for example motor, transmission and the like.
- the conveyor belt is in a conveying direction angetrie ben.
- the safety regulations for the transport of persons can be complied with with the passenger conveyor belt according to the invention.
- the operation of the passenger conveyor belt is efficient because the frictional forces are reduced as much as possible; It is therefore operated energy-efficient and cost-effective.
- the aforementioned method for producing a substructure element for a passenger conveyor belt has at least the following steps: In one step, a grate with a surface is provided. The surface is partially modified in a further step so that a part of the surface is designed as Rau Schl and another part of the surface as a sliding region.
- the grating can be made for example in a special casting process with a stamp.
- a commercial grid is used.
- the modification may include the entire surface of the grating, so that both the later Rau Scheme and the sliding area are processed.
- the grate has a surface finish that is already suitable, for example, for the gliding area, only the part of the surface for the later reeling area has to be modified and vice versa. This means that the later properties of an area can already be taken into account during the production of the grate so that a later modification can be dispensed with.
- the surface finish of the respective areas can be achieved by means of known methods, for example grinding, milling, planing, coating, application of additional materials, painting, edging and the like.
- a substructure according to the invention preferably also includes a Schaul. Support structure whose components are optionally connected in further steps of the manufacturing process with the grid, in particular screwed, are.
- the grate is preferably made of a plastic composite material, particularly preferably of fiberglass-reinforced plastic. It is a composite material of fibers, particularly preferably glass fibers, and a plastic.
- thermosetting plastics such. As polyester resin or epoxy resin, as well as thermoplastics, such as. As polyamide serve.
- Advantages of cost-effective glass fiber composites are the high elongation at break and the elastic energy absorption with low weight. They have an excellent corrosion behavior even in aggressive environments. Due to the low weight of the grid grid in this way, the substructure element is advantageously easy to transport.
- gratings are used with standard dimensions, as used for example for hole covers, cellars, stairs, etc. used. These then need - if necessary, only partially - to be surface-treated.
- the grate may also be assembled from smaller grate elements.
- the rapier area preferably has a sanding in a substructure element according to the invention.
- Sanding refers to a granular structure applied to the surface.
- the application can be carried out, for example, within the scope of the production method according to the invention by applying a granular material, such as quartz sand, together with a firmly adhering layer.
- the grain size is particularly preferably chosen so that the surface structure meets the requirements of the slip class R13.
- the grating can already be produced in its production in such a way that its surface is sufficiently lubricious for use as a sliding region.
- the sliding region preferably has a sliding coating. Examples of these are GRP coatings (glass fiber coatings), bonded coatings, PEEK (polyether ether ketone), PTFE (polytetrafluoroethylene), silicone, polyolefins and the like.
- GRP coatings glass fiber coatings
- PEEK polyether ether ketone
- PTFE polytetrafluoroethylene
- silicone polyolefins and the like.
- the frictional resistance can advantageously be further reduced.
- the grate can only have a sliding area and a Rau Schl.
- the sliding area is preferably arranged between two rapier areas.
- the sub-element comprises a number of cover elements and / or guide elements, which are arranged on at least one boundary between the sliding region and the Rau Scheme.
- the cover elements and the guide elements are each formed as a combined cover and guide element.
- they particularly preferably serve at the same time as cover and guide for the conveyor belt.
- the cover elements and / or guide elements can be designed, for example, as aluminum covers, which form a lateral boundary for the conveyor belt and are suitable for passenger transportation according to DIN-15700 Safety of belt conveyors for winter sports or leisure activities
- a substructure element according to the invention therefore preferably comprises a number of longitudinal members which are at least in one
- the longitudinal members are load-bearing elements which extend substantially in the longitudinal direction, ie in the conveying direction, of the substructure element, and the longitudinal beams are particularly preferably designed as profiles with a rectangular cross-sectional area, as is the case here a good balance between weight and bending stiffness can be achieved.
- connection between the longitudinal beams and the grate in the conveying direction is only "loose" means that it has a certain play in the conveying direction, that is to say that at a connecting point the grating can move a certain distance, particularly preferably 2, in relation to the longitudinal beams 4 mm, most preferably about 3 mm, this clearance is sufficient at distances of about 3 m between the connecting parts in order to avoid thermally induced material tensions.
- the connection can, for example, be made in a form-locking or positive-locking manner outside of this defined play In the vertical direction, the connection is designed as a relatively strict positive fit, ie a game is avoided in this direction as possible.
- the sub-element preferably comprises a number of supports, more preferably exactly two supports, which are firmly connected to the longitudinal members. Due to this distance, the amount of snow that may occur can at least partially find space between the grate or the passenger conveyor belt and the ground, so that the grate or the passenger conveyor belt must be freed of snow, dirt or precipitation less frequently.
- the supports may be formed, for example, as the supports of a scaffolding and are preferably adjustable in height by screwing or unscrewing.
- a substructure element preferably comprises at least one carrier roller for a conveyor belt return.
- the carrier roll is a rotatable element with a rotation axis parallel to the grid and perpendicular to the conveying direction. It serves to hang the conveyor belt in the area of its return, d. H. below the grate, to avoid. It is therefore arranged below the grate and the conveyor belt rests on her and runs in operation against the conveying direction on it. So it serves as a roller bearing, whereby the frictional resistance is reduced in the conveyor belt return.
- the gratings of adjacent substructure elements of the substructure preferably have a defined distance from one another.
- the distance is particularly preferably 0.5 to 3 cm, most preferably 1 to 2 cm. At this distance, a sufficient stability of the conveyor belt between the gratings is ensured, so that sagging of the conveyor belt is avoided.
- sufficient expansion joints for the thermal expansion of the gratings are provided in the substructure.
- the cover or guide elements of a substructure element preferably protrude beyond the substructure element and over to the respective adjacent substructure element of the row.
- a secure guidance of the conveyor belt is ensured even at the transition points between the substructure elements.
- a number of cover elements and / or guide elements are arranged on both sides of the conveyor belt so that they each connect flush to a strut of the grate, which each connect to a longitudinal member.
- the cover elements and the guide elements are preferably designed as a combined cover and guide element, as already described above, which extend as well as the side members parallel to the conveying direction.
- the struts are preferably longitudinal struts which extend parallel to the conveying direction.
- the conveyor belt and the cover or guide elements together form the center piece of an inverted U-shape, which is followed on both sides by a U-leg, which is formed in each case from a longitudinal strut and a longitudinal member.
- the U-legs are perpendicular to the center piece, so that an upwardly closed box is formed. Under this box, the return of the conveyor belt is preferably arranged so that it is largely shielded from precipitation upwards. As a result, icing of the return can advantageously be avoided.

- the plate element 27 is here preferably designed circular disk-shaped and has towards its center a countersink into which the head of the screw 25 is inserted.
- the outer edge of the plate member 27 engages over the longitudinal struts 4 and the transverse struts 4 '(not shown here) of the grating 3 and thus forms a positive connection with the grating 3 in the vertical direction.
- the screw 25 and the plate member 27 are not attracted so much that they act non-positively in the horizontal direction.
- in the conveying direction FR results in a certain game of about 3 mm. This can cause tensions be avoided, which would otherwise arise in thermal expansion of material in particular in the direction of the longest dimension of the grating 3, ie in the conveying direction FR.
- the passenger conveyor belt 2 described can be produced inexpensively and for the most part from commercially available components.
- the design of the grate 3 according to the invention ensures that the security requirements imposed on the passenger transport are met.
- the entire conveyor belt substructure 10 is designed so that significant problems such. As icing, exemption from precipitation, thermal loads or the like can be avoided during operation under adverse weather conditions.
