Definitions
- the invention relates to an escalator or moving walk with a step belt with steps or with a pallet belt with pallets for the transport of persons and / or objects and provided with an anti-slip coating stages or pallets.
- Driving devices in the context of the invention which may also be referred to as conveyors are escalators and moving walks with a variety of rode units or stages or pavement pallets, which are connected to an endless conveyor. Users of the driving devices stand on treads of the stepping units or steps or they travel on the moving platform pallets or escalator steps in the same direction of movement as the driving devices drive or move.
- fluororesin is too costly and expensive to handle. Fluororesin coated steps or pallets have proven too expensive. However, there have been additional problems such as a lack of durability because the fluororesin tends to wear quickly and to be easily removed. The work of disassembling the entire escalator and removing the steps to be repaired will be needed to rebuild the removed fluororesin. This results in increased maintenance costs and, above all, the escalator or moving walk is not ready for use during such maintenance.
- Coating degrades relatively quickly. This leads in practice to the fact that the steps or pallets must be removed and recoated, as mentioned. However, the associated effort or work time is too high. To increase the durability of the coating, one would have to apply significantly thicker layers. Thicker layers, however, bring with them other problems. For example, the cleaning of the corresponding steps is made impossible. The invention is intended to remedy this situation.
- the invention as characterized in claim 1, solves the problem by a special type of coating is chosen, which is significantly thinner contrary to the previous approaches. That is, according to the invention, one goes in a direction that should actually promise no success, as the skilled person would rather apply a thicker layer in order to increase the effect and the stability or durability.
- coating technique which ensures a very thin and adherent bond between the coating and the aluminum stage or metal stage or the aluminum pallet or metal pallet.
- coating materials have been selected which enable a particularly intimate and reliable coating of the metal parts or aluminum parts or steel parts or NIROSTA parts or copper parts or brass parts, magnesium parts.
- Steps or pallets is not affected by the application of the coating.
- the function and the safe, quiet, clean, smooth running of the entire conveyor are not affected by the coating. It should also be emphasized as important that the coating has a very long fatigue life or Abtrittsfesttechnik or durability or wear resistance.
- Fig. 1 is a side view of an escalator according to the invention
- Fig. 2 is a side view of an inventive
- Fig. 3 is a plan view of a pallet or stage of a conveyor according to the invention.
- FIG. 44 shows an elevation of a pallet with anti-slip coating of a conveying device according to the invention
- Fig. 5 is a plan view of an end part or head of a conveyor according to the invention.
- Fig. 6 is a side view of the comb plates and on the bottom covers of an inventive
- Fig. 1 shows an escalator 1, which connects a first floor El with a second floor E2.
- the escalator 1 has a step band consisting of stages 4. In the case of a moving walk 1, as shown in Fig. 2, this has an existing pallets 4 pallet strip.
- a handrail 3 is arranged on a balustrade 2 which is held at the lower end by means of a balustrade pedestal.
- FIG. 3 shows a schematic representation of a pallet or step on which between two to six strips of anti-slip coating 4.1 made of carbide are applied or sprayed.
- FIG. 4 shows a pallet 4 with a
- Non-slip coating 4.1 made of a hard metal layer, in which carbide hard materials (tungsten carbide, chromium carbide, titanium carbide, nickel carbide or silicon carbide) in a metallic matrix are stored.
- the carbide layer is on the tread area of the pavement pallet 4, over the entire length, applied.
- two longitudinal carbide strips are sprayed on.
- FIG. 5 shows an end portion El, E2 and a head portion of a moving walk 1 and escalator 1 with anti-slip coating 4.1, which is applied to the pallets 4 and 4 stages.
- an anti-slip coating 4.1 is available in strips on the ridges. This version provides optimal protection against sliding away or slipping.
- the carbide layer is sprayed or sprayed in two to six strips per bottom cover 9 or comb plate 7, 8.
- Figure 6 shows the schematic representation of the comb plates 7.8 and the bottom covers 9 with anti-slip coating 4.1 carbide.
- the hard metal layer 4.1 made of carbide hard material, clings to the metal parts or aluminum parts and deposits in the existing metallic matrix.
- the surface of the components or metal parts is fine-grained and weather-resistant, enclosed by the anti-slip coating 4.1. This is applied in strips by means of a high-speed flame spraying process. This creates a non-slip surface that prevents excellent slipping or slipping.
- conveyor is used instead of the term "escalator" or "moving walk”.
- a metallic powder material is accelerated and heated by means of an injection process. Then, a jet of the heated and accelerated powder material is directed onto the surface to be coated by means of a spray gun. This is done so that when hitting the metal surface to be coated or alloy surface or aluminum surface, a homogeneous and fine-grained layer of a carbide hard material results, which is embedded in the metallic matrix.
- the metallic powder material used is preferably a material comprising tungsten and / or chromium and / or titanium and / or nickel and / or silicon.
- a high-speed flame spraying process in which a mixture of oxygen and a fuel, preferably a fuel gas (propane or propylene), is used to heat and accelerate the powder material.
- a fuel gas propane or propylene
- a liquid fuel for example kerosene
- the spray material is conducted using nitrogen as a carrier gas in powder form coaxially through a nozzle, enveloped by the flame and therefore uniformly melted, and passed out of the spray gun.
- Hoch Anthonys flame spraying the powder material is sprayed at very high speed on the metal workpiece to be coated or alloy workpiece or aluminum workpiece.
- the heat to melt the powder material is generated by the reaction of oxygen and fuel (eg propane, propylene, natural gas, hydrogen, kerosene) in the combustion chamber.
- oxygen and fuel eg propane, propylene, natural gas, hydrogen, kerosene
- the temperatures reached in the flame are up to about 3000 - 4000 0 C, so that the powder material can be sprayed.
- the gas expands and accelerates the powder material up to speeds of 400-900 m / s.
- the workpiece surface ie the metal surface or the alloy surface or the aluminum steps or pallets 4 need not be previously sandblasted or roughened, because when hitting the powder material on the workpiece a kind of welding, respectively an adhesive bond and clamping, between powder material and workpiece takes place. Due to the high speed of the powder high-speed flame spraying achieves good adhesion of the metallic powder to the workpiece and low porosity. In addition, by choosing a suitable metallic powder, a better material can be produced or established which is perfectly suitable as anti-slip material. As a result, the base material (brass, copper, NIROSTA, steel, magnesium, aluminum) of grade 4 or pallet 4 is upgraded and perfected without errors.
- tungsten, chromium, titanium, nickel or silicon is used as the metallic powder
- high-speed flame spraying produces optimal layers of tungsten carbide, chromium carbide, titanium carbide, nickel carbide or silicon carbide.
- the layer thickness according to the invention is preferably less than 0.08 mm to 0.2 mm. The porosity of the layers goes to zero.
- the resulting in the process according to the invention layers are denser and adhere more firmly than other spraying methods such as commercial flame spraying, arc spraying or plasma spraying.
- the inventive method is particularly suitable for hard metal layers in which carbide hard materials (Tungsten carbide, chromium carbide, titanium carbide, nickel carbide or silicon carbide) are embedded in a metallic matrix. It can be produced layers that are characterized by high wear resistance and / or stability or durability and / or resistance or durability or constancy.
- carbide hard materials Tungsten carbide, chromium carbide, titanium carbide, nickel carbide or silicon carbide
- the effluent gas jet is used to melt and reflow the individual particles of the metallic powder material and accelerate to a high velocity that is about four to five times greater than conventional flame spraying.
- the high speed flame spraying process very effectively utilizes the high kinetic energy of the powder material and, to a limited extent, thermal energy to produce dense, compact layers with low porosity and high adhesive strength.
- Some of the layers thus produced have an adhesive tensile strength of more than 83 MPa (equivalent to about 83 N / mm 2) and an extremely fine-grained surface.
- the process uses, as mentioned, a mixture of oxygen and a fuel, which is supplied either in gaseous form or as a liquid fuel. Therefore, there are two types of spray systems: the gas powered systems use propylene, propane, hydrogen or natural gas; Kerosene is used in the liquid fuel systems.
- the corresponding fuel is carefully mixed with oxygen within the spray gun, exits through a nozzle and is ignited there.
- the powder material is preferably coaxially passed through this nozzle using nitrogen as a carrier gas in powder form, enveloped by the flame and therefore melted uniformly.
- these layers Due to the low particle temperature compared to the other thermal spraying methods, these layers have a predictable chemical composition and are almost homogeneous. In addition, the layers have a fine-grained structure.
- the anti-slip coating according to the invention offers excellent protection of the steps 4 or pallets 4 and on the other hand a coating which does not or hardly wears off in the anti-slip effect even after prolonged use.
- the thickness of the carbide layer remains the same for at least 5 to 10 years and there is no erosion or weathering or corrosion tendency.
- the anti-slip coating additionally extends in an excellent way the life of the coated components.
- the anti-slip coating has after coating a very fine-grained surface, a uniform composition and low porosity and is considered finished. That is, it requires no further processing step or no further surface treatment.
- the carbide layers according to the invention are characterized by a high hardness of almost 1400 HV (Vickers hardness).
- FIG. 3 Particularly preferred is an embodiment of the invention, which is shown in Figure 3.
- the complete surface is coated, but only a number of strips 4.1 (preferably between two to six strips per pallet or step) with strip widths of 20mm to 75mm are applied. This measure reduces the amount of powder material used. The anti-slip effect is still sufficient, since the strips 4.1 provide sufficient adhesion.
- the invention can be equally applied to escalators and moving walks.
