Embodiment Construction

[0017] In the drawings, a plowing device according to the invention is generally indicated with the reference number 10, which has a plowing blade 1, which is connected between end-mounted chain drives 3 and 4 for the plowing chain 2 by means of a plowing chain. forward and reverse reciprocating motion. exist figure 1 The forward and reverse motion of middle planer 1 is represented by double arrow F. The two chain drives 3, 4 are designed identically in principle and comprise a sprocket 6 supported on the drive shaft 5, a transmission box 7 and a drive motor 8, which in the shown embodiment is a belt drive respectively. There is, for example, an inverter motor with an inverter control circuit provided in a separate switch box 9 . During continuous operation, the variable frequency motor can be operated at a rotational speed variably at a rotational speed within a comparatively large bandwidth, for example 80 to 1800 l / min, wherein the rotational speed of the drive motor 8 is...

Abstract

The invention relates to a coal plowing device and a method for controlling the coal plowing device, comprising: a mining planer (1) capable of forward and reverse movement by means of a planer traction chain (2); at least two drive units with adjustable speed Chain drive (3, 4) of the motor (8); a planer stroke measuring system and a motor control device (11), which provides, for example, position-controlled control for varying the rotational speed of the drive motor (8) parameters to vary the speed of the planer, and the motor control unit is equipped with a control module (12) with automatic load balance adjustment between the drive motors (8). According to the invention, a monitoring module (13) is provided, which for example switches off the control module (12) for load balance regulation in a position-controlled manner or modifies its mode of operation and provides different control parameters (S , S').

Description

technical field [0001] The invention relates to a coal plowing device, which has: a mining planer that can move forward and reverse by means of a planer traction chain and reciprocally moves between the end stops of the planer; at least two driving motors with an adjustable speed, respectively, A transmission box and a chain drive of the planer sprocket meshing with the chain links of the planer traction chain; a planer stroke measuring system and a motor control device, which is provided, for example, program-controlled or position-controlled for changing Control parameters of the rotational speed of the drive motors to vary the planer speed, and the motor control unit is assigned a control module with automatic load balancing between the drive motors of the chain drive. Secondly, the present invention also relates to a method for controlling a coal plowing device, in particular a plowing device for underground mining. Chain transmission device; a mining planer driven by the...
