Embodiment Construction

[0015] 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. The forward and reverse movement of planer 1 is indicated by double arrow F in FIG. 1 . 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 frequency converter motor 8 can be operated variable in speed at a speed within a comparatively large bandwidth, for example 80 to 1800 l / min, wherein the speed of rotation of the drive sprocket 6 and the operating speed of the ...

Abstract

The invention relates to a planing device and to a method for activating a planing device, with a mining planer 1 reversibly moveable by means of a planer chain 2, with at least two chain drives 3, 4 having variable-speed drive motors 8, with a planer travel measurement system and with a motor control device 11 which, for example by position control, delivers activation parameters for a change in rotational speed of the drive motors 8 for changing the planing speed and which is assigned a control module 12 with automatic load compensation regulation between the drive motors 8. According to the invention, a monitoring module 13 is provided, which, for example by position control, switches off the control module 12 for load compensation regulation or modifies its operating mode and delivers different activation parameters S, S' to the drive motors 8.

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...
