A dynamic simulation test device for electric control system of mine winch

Abstract

The invention discloses a dynamic simulation test device for an electric control system of a mining winch, which comprises a bottom platform, a bracket fixed on the bottom platform, a transmission device and a detection device; the transmission device includes a driving device horizontally arranged on the bottom platform, and The drive wheel 1 and the bevel gear pair are fixedly connected in sequence at the output end of the driving device, the two ends are longitudinally fixed on the bracket through bearings and the screw whose bottom end is connected to the output end of the bevel gear pair, and the drive wheel is connected to the drive wheel 1 through a belt 2. The detection device includes a mounting plate fixed longitudinally on the bracket and located on one side of the lead screw, several travel switches arranged at intervals on the mounting plate, threaded with the lead screw and used to trigger the slide block of each travel switch, set Encoder 1 on the top of the lead screw, and encoder 2 fixedly connected to the drive wheel 2; truly reflect the internal hardware and software logic relationship of each travel switch and encoder, effectively reduce false detection and missed detection, and ensure that the travel switch and encoder effectiveness.

Description

technical field [0001] The invention relates to a simulation test device, in particular to a dynamic simulation test device for an electric control system of a mining winch. Background technique [0002] Mine winch electric control system (refer to figure 1 (shown) is mainly composed of the operating table, PLC box (including main and auxiliary PLC, circuit breaker, contactor, relay, switching power supply, etc.) Brake clearance, spring fatigue and other detection sensors, in which all kinds of travel switches installed on the depth indicator, such as upper overroll point, upper stop point, upper deceleration point, upper synchronization point, lower synchronization point, lower deceleration point, lower stop Travel switches such as the upper and lower overwind points, the incremental encoder 1 installed coaxially with the rotation axis of the depth indicator, and the incremental encoder 2 that rotates synchronously with the low-speed side of the reduction box according to ...

AI Technical Summary

Problems solved by technology

[0004] In order to comprehensively test the effectiveness, hardware logic and software logic of the above travel switch and encoder during the delivery stage of the winch electric control system, a static test bench was often used before To complete, that is, the limit switch and the encoder are installed in a simple test bench, and the limit switch action and the encoder are rotated manually. This method cannot directly reflect the above-mentioned sensing elements in hardware and software from the hardware facilities. The internal logical relationship on the test depends entirely on the personal skills of the testers, there are cases of false detection and missed detection, and the detection effect is not ideal
