Definitions

  • the present invention relates to a method for installing a conveyor chain for a pallet belt of a moving walk, a method for replacing a connecting element in a conveyor chain and a method for installing a pallet belt for a moving walk, and such a conveyor chain, a pallet belt with such a conveyor chain and a moving walk with such a pallet strap.
  • Moving walks are used as passenger transport systems to transport people within a building along a travel path that is usually horizontal or only slightly inclined.
  • a moving walk has a pallet belt on which passengers can stand and which can be moved in all directions along the travel path.
  • a large number of pallets are arranged one behind the other on the pallet belt.
  • Each of the pallets is typically mounted between two conveyor chains positioned along opposite sides of the pallet belt.
  • Each of the conveyor chains is in turn composed of a large number of elongated chain links, which are arranged one behind the other at a spacing and are pivotably connected to one another via chain pins, so that the entire conveyor chain can withstand high tensile loads.
  • the spacing essentially corresponds to the distance between the central longitudinal axes of the chain pins.
  • the pallet belt is arranged all around. This means that the pallets can be moved in a forward direction along the travel path using the conveyor chains. At the ends of the travel path, the pallet belt is deflected by deflection devices so that the pallets with the pallet belt that is closed in the form of a ring can be moved in the opposite return direction back to the start of the travel path.
  • deflection devices usually have deflection sprockets, which each interact with one of the conveyor chains in order to deflect it from the forward direction to the return direction or vice versa, generally by 180°.
  • a moving walk is to be installed in a building that is to be newly built, it can be provided that at least parts of the moving walk are integrated in a floor of the building, so that a running surface formed by the pallets in advance can end as flush as possible with a surface of this floor. It can be advantageous to provide moving walks with a low overall height for this purpose so that no deep pits in which the moving walk can be accommodated have to be provided in the floors of the structure.
  • a moving walk is to be retrofitted in an already existing building, it may not be possible or at least very expensive in some cases, for example for reasons of statics, to sink it at least partially in a floor of the building. In this case, the moving walk must be set up on the floor of the structure.
  • a height difference between a level on which the running surface of the moving walk runs and a level of the surrounding ground should be as small as possible.
  • the aim should be to use a moving walkway with a particularly low overall height.
  • the overall height of a moving walk is largely determined by the overall height of its deflection devices and in particular by a diameter of the deflection chain wheels used therein, which are usually arranged vertically.
  • so-called polygon effects can occur due to the fact that not arbitrarily narrow pallets can be used, but the pallets have a minimum length for practical use (measured in the direction of the travel path).
  • Such polygon effects can occur noticeably if the length of the pallets and the associated pitch of the conveyor chain are not sufficiently small compared to the diameter of the deflection sprockets.
  • a minimum number of teeth of the deflection sprockets of 17 teeth and thus a minimum overall height was usually not undercut in conventional moving walks.
  • a pallet belt for use in a conveyor system, in particular a moving walkway is described.
  • the pallet belt described has two conveyor chains and pallets arranged between them.
  • This pallet strap due to its structural design, can help to some extent Limiting polygon effects even when using small deflection sprockets.
  • the structural design of the pallet belt described is relatively fragile and has a large number of safety-relevant components which, in the event of incorrect assembly or failure, could lead to dangerous situations for the user.
  • connection elements that are adjacent in the direction of extension can be arranged so as to overlap one another.
  • a second end of a front of the two connection elements and a first end of a rear of the two connection elements are each coupled to a common two-part chain pin. This is done in that the first chain pin part of the common two-part chain pin is coupled to the second end of the front of the two connection elements and the second chain pin part of the common two-part chain pin is coupled to the first end of the rear of the two connection elements.
  • the first end of each of the connecting elements can be coupled to the respective first two-part chain pin in a pivotable and coaxially positioned manner and the second end of each of the connecting elements can be pivoted to the respective second two-part chain pin and can be coupled in the direction of extension over a predetermined distance be coupled linearly displaceable out.
  • at least one of the connection elements is first coupled with the second end during the coupling process by sliding it on in the axial direction with the associated first chain pin part of the respective first two-part chain pin. Then the first end with the associated second chain pin part of the respective second two-part Coupled chain pin by the second chain pin part is firmly connected to the first chain pin part of the respective second two-part chain pin.
  • the features coupling, coupling, coupled is understood in the present document to mean a connection that enables relative movements between the coupled parts in at least one direction of movement, but which does not allow the coupled parts to be separated without additional effort.
  • Such an additional effort can be, for example, the loosening of a screw, a nut, a cotter pin, the actuation of a snap-in device or even an irreversible destruction of a coupling component and the like in order to break the coupling of the parts.
  • a pluggable structure can be provided between the first chain pin part and the second chain pin part, so that the second chain pin part can be plugged together with the first chain pin part during assembly.
  • an anti-twist device can be provided between the first chain pin part and the second chain pin part, which prevents the first chain pin part from twisting relative to the second chain pin part in a positive and/or cohesive manner.
  • Projection and depression structures formed on the chain bolt parts for example, such as spring washers according to DIN 6796, can be provided as form-fitting anti-twist devices. In this case, these structures can also be provided on only one of the chain pin parts, with their projections being embossed in the other chain pin part during assembly. Additional machine elements such as pins or the like are also possible. Cohesive anti-twist devices such as anaerobic-curing adhesives are particularly advantageous.

  • the respective two-part chain pin can extend through these in the coupled state.
  • the first end of the connecting elements can each be held on the associated two-part chain pin via a sliding element, the sliding element being arranged on the associated two-part chain pin before the connecting element is pushed on axially. After the attachment element has been slid on axially, the sliding element is interposed between opposing surfaces of the attachment element on the one hand and the associated two-part chain pin on the other hand.
  • the second end of the connecting element can be held on the associated two-part chain pin via a bushing, so that the bushing is interposed between the through-opening of the connecting element on the one hand and the associated two-part chain pin on the other when the connecting element is pushed on axially.

  • a method for replacing a connection element in a conveyor chain is proposed.
  • the conveyor chain was assembled according to a method of the type described above and has corresponding structural properties resulting from these assembly methods.
  • the method has at least the following steps, possibly, but not necessarily, in the specified order: First, the second chain pin part of the second two-part chain pin associated with the connection element to be exchanged is removed. Then, by pivoting the connection element following the connection element to be exchanged, the second end of the connection element to be exchanged is released, so that it can be decoupled from the associated second chain pin. After that you can Subtracting the first end and second end in the axial direction, the connection element to be replaced can be decoupled from the associated two-part chain pin.
  • connection element detached and removed in this way can now be replaced by a replacement connection element.
  • This is done by coupling the replacement connection element by sliding it in the axial direction onto the associated first and second two-part chain pins.
  • the following connection element has to be coupled to the second two-part chain pin belonging to the replacement replacement element.
