The present invention discloses a dynamic reliability evaluation method for coupling faults of a middle trough of a scraper conveyor. Approximation precision of a moment-based saddlepoint approximation method and a function attribute of dynamic t-copula are fully utilized, and the dynamic reliability evaluation method for the coupling faults of the middle trough of the scraper conveyor is provided, so that dynamic correlation between failure modes of the middle trough of the scraper conveyor under a small sample condition is more accurately described, and accuracy of dynamic reliability evaluation of the coupling faults of the middle trough of the scraper conveyor is improved.

A device for examining a conveyor system having one or more motorized rollers comprises a measuring unit for determining a current profile of the motorized roller, wherein the measuring unit has a first interface and a second interface which are adapted to switch the measuring unit in the conveyor system between the motorized roller and a control unit controlling the motorized roller. A third interface is provided for receiving data on an operating situation present during the determination of the current profile. An evaluation unit is adapted to compare the determined current profile of the motorized roller with a reference profile which is characteristic for the operating situation.

A shoe sorter is described. The shoe sorter can include a switch plate that supports movement of a shoe pin of a pusher shoe, a finger, and an actuation arm. In some examples, the finger can be configured to be moved in a first direction in response to a portion of the shoe pin contacting a portion of the finger. The actuation arm can be pivotably engaged to the finger so that a movement of the finger in the first direction can cause a movement of the actuation arm in a second direction. In this regard, the actuation arm in the second direction can cause a change in a signal outputted by the photoelectric sensor coupled to the shoe sorter. This change in the signal can be used by a processor to determine that the shoe pin is misaligned.

Systems and methods are provided for conveyor operation and maintenance that employ one or both of a “smart shoe” technology where one or more conveyor shoes incorporate features, such as an RFID tag, and a “missing pin detection” technology where one or more pin components of conveyor shoes incorporate features, such as an RFID tag, allowing selective wireless tracking and identification capability. A conveyor system comprises a shoe management system allowing interactions directly with one or more RFID readers, which can detect, store and/or monitor information associated with “smart shoe” and/or “missing pin detection” RFID tags, where interface between this application and the reader can be implemented via a socket interface. An open platform communications (OPC) wrapper can be created around the interface so that a Human Machine Interface (HMI) could interact directly with shoe management system.

A tower lift includes a rail module extending in a vertical direction, a plurality of carriage modules that are movable along the rail module, each carriage module having a carriage that carries an object, and an interference avoidance module that avoids travel interference between the carriage modules that move along the rail module.

A method for wear detection during the operation of a conveying system having a closed circulating path, a pick-up which is attached to at least one running gear and which makes contact with a surface of a rail in the case of wear of the wheel and/or the rail, includes using a sensor coupled to the pick-up to register vibrations produced by the contact. The vibrations are transmitted wirelessly to a background system and are evaluated. The method and a conveying system allow wear detection, in particular in the case of closed conveying systems, and considerably reduce maintenance complexity.

1. —It is disclosed an autonomous monitoring system based on a magnetic field variation: (a) that allows (i) predicting wear, failures and cracks in mining equipment; (ii) prevent and detect, in real time, uncrushable material such as metal and/or material from “old mining” or past operations and/or parts or pieces of mining equipment; (b) to be used/installed in mining and/or loading equipment, such as, but not limited to, cables shovel, hydraulic shovel, a loader or other type of loader; (c) that allows detecting strange metal bodies, and also, knowing the level of wear and/or detecting a failure or fracture in the parts of these equipment almost immediately, particularly, but not limited to, the teeth or part of them, preventing unscheduled stops and accidents of the personnel, and improving effectiveness and efficiency in the planning of predictive and preventative maintenance operations; 2.—an installation method of the system. 3.—an operating method of the system. 4.—tooth, ground engaging tool or part of a mining and/or loading equipment, which comprises one or more monitoring devices.

A conveyor belt condition monitoring apparatus is U-shaped, with two parallel arms arranged to extend across a conveyor belt from the side. The arms include ultrasonic sensors arranged to measure the distance to respective surfaces of the conveyor belt. One arm includes an eddy-current sensor arranged to measure the distance to a metallic core of the belt. The apparatus is arranged to be moved across the belt to provide a profile of belt condition across the width of the belt.

In this regard, the actuation arm in the second direction can cause a change in a signal outputted by the photoelectric sensor coupled to the shoe sorter. This change in the signal can be used by a processor to determine that the shoe pin is misaligned.
