Problems solved by technology

[0005] The disadvantage of this technical solution is that a mechanical contact must be created between the pulse trigger and the current collector
This mechanical actuation of the pulse trigger can however also be triggered by careless operators, animals or objects
In addition, when used in areas with a risk of corrosion, for example in large harbor installations with salty sea air, there is the risk that the movable parts of the pulse trigger corrode over time and are then no longer can trigger correctly

Embodiment Construction

[0029] figure 1 A schematic three-dimensional view of a section of a conductor line system 1 according to the invention is shown, which has a conductor conductor 2 extending in the longitudinal direction L. FIG.

[0030] The conductor conductor 2 has an elongated insulating profile 3 which surrounds an elongated, electrically conductive phase conductor profile 4 with an embedded electrically conductive, elongated sliding contact surface 5 which preferably Made of aluminum or steel.

[0031] Current collectors 6 of electrical consumers, not shown in the figure, can be moved along the conductor lines 2 . In this case, the current collector 6 is used to supply electrical consumers movable along the trolley line and electrical devices mounted thereon with different electric running gears and lifting gears, such as electric overhead conveyors or container cranes.

[0032] The current collector 6 has a sliding contact 7 designed as a carbon brush, which during operation moves agai...

Abstract

The invention relates to a device (11) and a method for the detection of the wear of a sliding contact (7, 7') which may be displaced along a brushgear (2), having a sensor (13; 113, 113') and a measurement indicator (12; 112, 112') designed for detection by the sensor (13; 113, 113') wherein the sensor (13; 113, 113') and the measurement indicator (12; 112, 112') approach or move away from each other by a shortening of the sliding contact (7, 7') caused by wear, and a brushgear system (1; 101). The invention addresses the problem of enabling simple, reliable detection in good time of the practically complete wear of the sliding contact by means of a device of this kind in which the sensor (13; 113, 113') is designed for the contactless and / or contacting detection of the measurement indicator (12; 112, 112'), and by means of a method of this kind in which the sensor (13; 113, 113') detects the measurement indicator (12; 112, 112') becoming closer to the sensor (13; 113, 113') contactlessly and / or contactingly and, when a threshold value for a predetermined wear of the sliding contact (7, 7') is exceeded, issues a warning signal, and also a brushgear system (1; 101) having a device(11) of this kind.

Description

technical field [0001] The invention relates to a device according to the preamble of claim 1 for detecting wear of a sliding contact movable along a trolley conductor / line, a device according to the preamble of claim 12 Partially described contact wire system and a method for detecting wear of a sliding contact movable along a contact wire according to the preamble of claim 18 . Background technique [0002] In the known conductor wire system, the current collectors of the movable loads are guided along a stationary conductor. The current collector holds a sliding contact, preferably a carbon brush, in the sliding contact holder / carrier, which contacts an electrically conductive sliding contact surface on the sliding conductor. Due to the movement of the sliding contact on the conductor wire and due to the transmission of electrical energy via this contact-based connection, the sliding contact wears away over time. In order to ensure that the sliding contact remains secur...
