The structural integrity of wheel sets used in rolling stock is of great importance to the rail industry and its customers. A number of rail accidents have been directly related to the failure of train axles, leading to increased demands for their inspection and maintenance. Visual inspection and Magnetic Particle Inspection are the current standard practices used for manual non-destructive testing of axles. However, these processes require removal of the wheelset from the wagon/locomotive bogie and full disassembly in order to facilitate access. Inspection is also carried out by some wagon providers using ultrasonic testing (UT) but its application is also limited to disassembled wheelsets. An axle on a wheelset can be connected to a number of ancillary components including breaks and bearings. The disassembly (and reassembly) of axles from the wheelsets/wagon bogey is therefore very time consuming and expensive. There is evidence that even partial disassembly and reassembly could introduce future axle reliability problems. To minimise disruption to their train services but ensure continued safety, train operators require frequent and regular inspection methods that allow quick inspection at the depot with the minimum of wheelset and bogie disassembly. The AxleInspect project aims to develop new inspection techniques based on phased array ultrasonic and electromagnetic techniques suitable for the inspection of both solid and hollow axles. For solid axles, inspection techniques are to be developed that inspect from the end face of the axles using new and novel phased array ultrasonic inspection technology. For hollow axles, probes based on UT and electromagnetic inspection techniques are to be developed, enabling detection of surface breaking cracks that cannot be found by ultrasonic inspection. These new techniques will allow inspection of axles whilst they are still attached to their supporting bogey, allowing minimal wheelset disassembly from the train.

The invention is directed to an apparatus for continuous and non-destructive monitoring of the connection of a conveyor belt. During movement of the conveyor belt, a radiation source emits rays in the direction of the belt surface. The rays are of such high energy that they penetrate the conveyor belt and the connection thereof within a material-free region. A sensor detects the rays which have passed through. A process computer evaluates the result of the radiographic examination by comparing the actual connection values to set connection values and connection limit values. The radiation source and the sensor are accommodated in a housing. The housing has two openings between the radiation source and the sensor through which the moving conveyor belt passes without contact. The housing is integrated into the lower run of a conveyor system.

A conveyor belt has a carrying side cover plate and a running side cover plate each of a polymer material having elastic properties. The conveyor belt defines a conveyor belt longitudinal direction (X) and has an embedded reinforcement and at least one of the cover plates is provided with a hybrid conductor loop. The hybrid conductor loop communicates in a contactless manner with an interrogation station in the form of a transmitter/receiver pair. The hybrid conductor loop has a flattened conductor cross section and runs in the conveyor belt obliquely at an angle () relative to the conveyor belt transverse direction (Y) to form a diagonal direction (Z). The transverse direction (Y) is at right angles to the longitudinal direction (X). The arrangement of the transmitter/receiver pair is adapted to the diagonal direction (Z) to so increase the mutual spacing of the transmitter and the receiver.

A conveying arrangement includes a conveyor belt having a carrying-side cover plate and a running-side cover plate. The conveying arrangement further includes a drive drum, a reversing drum, carrying rollers and a carrying structure. The conveying arrangement forms a material-conveying upper strand (A) with a charging location for the conveyed goods and a lower strand (B). A device for generating current is provided at the charging location for the conveyed goods underneath the conveyor belt of the upper strand (A). The device includes an impact bearing having sliding properties for the running-side cover plate of the conveyor belt of the upper strand (A). A generator is operatively connected to the impact bearing and a supporting device is provided for the generator. The generator converts at least part of the impact energy of the conveyed goods into electric current.

A system for the non-destructive inspection of a conveyor belt which includes a cover on the carrying side, a cover on the backing side, each cover being made of elastomeric material, and embedded tension members. While the conveyor belt is moving, a radiation source emits rays to the belt surface which are of such high energy that the rays pass through the belt within a region free of material disposed on the belt. A sensor detects the rays passing through the belt. A processor is operatively connected to the sensor and evaluates the result of the radiographic check. The radiation source and the sensor are accommodated in a housing, wherein, between the radiation source and the sensor, there are two housing openings through which the moving belt runs without contact.

An apparatus non-destructively inspects a conveyor belt in a production facility. The conveyor belt defines a belt surface and has cover plates made of a rubber mixture. The production facility includes a vulcanizing press for vulcanizing the conveyor belt during production thereof. The apparatus includes a housing forward or rearward of the press. The housing has openings through which the conveyor belt passes. A radiation source mounted in the housing transmits rays toward the belt surface and the radiation source is configured to transmit the rays with energy sufficient to cause the rays to pass through the conveyor belt. A sensor mounted in the housing detects the rays passed through the conveyor belt to facilitate a radiographic check by providing actual values of the conveyor belt. A processor evaluates the radiographic check by comparing the actual values of the conveyor belt to set values of the conveyor belt.
