A belt conveyor has at least one drum. The drum has a drum axle and a drum body with a drum shell and drum bases. The drum axle is mounted on the two sides by way of two bearings. A force measuring device and/or an accelerometer are arranged on the drum axle on the two sides. The sensors which are arranged on the two sides are preferably arranged between the drum body and the bearing outside the drum body. The sensor signals can be transmitted wirelessly by way of a telecommunications device which is assigned to the sensors.

Belt conveyor and drum for a belt conveyor

A method for monitoring a belt conveyor with a circulating conveyor belt includes the steps of determining at least one operating parameter of the belt conveyor; determining running resistances at different points along the conveyor belt on the basis of the at least one determined operating parameter; determining a sum of the determined running resistances over the length of the conveyor belt; and adapting the determination of the running resistances, in order to minimize a deviation of the drive power which is calculated from the determined sum from the measured drive power.

Determination of the energy efficiency of a belt conveyor

A method of operating a chain drive that includes sprockets. Tensile chain moments on the sprockets are determined and a specification value for operating the chain drive is determined therefrom in an automated manner. A corresponding assembly has a chain drive with sprockets and with a control device at least partly associated with the chain drive. The control device is configured for carrying out the method and a specification value for load distribution among the two drives for operating the chain drive is determined therefrom in an automated manner.

Method for operating a chain drive and assembly having a chain drive

A belt conveyor and a method for determining an energy consumption of a belt conveyor on a basis of conveyor belt segments or on a basis of installation sections of the belt conveyor. The belt conveyor has at least one drive for driving a conveyor belt formed of conveyor belt segments. The belt conveyor has a control device, which is fed signals of a first sensor system for sensing the energy consumption of the drive and of a second sensor system for sensing a loading that can be assigned to a section of the conveyor belt and of a third sensor system for detecting connecting sections between conveyor belt segments. The control device determines an energy consumption on the basis of installation sections and/or conveyor belt segments.

Method and apparatus for determining a specific energy consumption of belt conveyors

A force measuring unit for measuring a force applied to an individual chain link of a chain strand is used in underground mining applications. The force measuring unit may include a housing having a first end configured to be contacted by a first chain link leg and a second end configured to be contacted by a second chain link leg, and a distance measuring device accommodated within the housing and configured to measure an actual distance between the first chain link leg and the second chain link leg. The distance measuring device may include a first unit part configured to be contacted by the first chain link leg and a second unit part configured to be contacted by the second chain link leg.

Force measuring unit and system for measuring chain forces

A planing device and a method for activating a planing device, with a mining planer reversibly moveable by means of a planer chain, with at least two chain drives having variable-speed drive motors, with a planer travel measurement system and with a motor control device which, for example by position control, delivers activation parameters for a change in rotational speed of the drive motors for changing the planing speed and which is assigned a control modulewith automatic load compensation regulation between the drive motors. A monitoring module is provided, which, for example by position control, switches off the control module for load compensation regulation or modifies its operating mode and delivers different activation parameters to the drive motors.

Planing device and method for activating a planning device

A method of monitoring belt orientation and/or belt travel of a belt conveyor apparatus includes measurement of compression and/or thrust stress patterns within the belt as it passes over a support roller arrangement by measuring means embedded in the belt. The measured signal is recorded and associated with a specific support roller. The signal pattern allows conclusions to be drawn about misalignments of the belt or possible defects in the support rollers. A belt conveyor apparatus has measuring means embedded in the belt and including at least one multi-axis sensor for detecting the stress variations in the belt.

The invention relates to a method for the control of the chain drive mechanisms of underground working machines and a correspondingly equipped chain scraper conveyor. The invention proposes to filter out a detection signal (S ), representative of the currently arising vibrations of the chain ( ), from the operating data of the main and auxiliary drives (I, II) by means of a detection device ( ), and to take this to an active suppressor ( ), which generates a time-variable control signal (S ) in accordance with a suppressor function, with which, in the frequency range of the vibration of the chain, a change is effected to a control value, e.g. (S ) for the closing pressure adjustment of a multiple disc clutch ( ) of at least one drive unit for the suppression of vibration by the abstraction of energy from, or the introduction of energy into the chain ( ).
