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

Abstract

The invention discloses a dynamic simulation test device for an electric control system of a mining winch. The dynamic simulation test device comprises a bottom platform, a bracket fixed on the bottom platform, a transmission device and a detection device, wherein the transmission device comprises a driving device which is horizontally arranged on the bottom platform, a transmission wheel I and a bevel gear pair which are fixedly connected in sequence with the output end of the driving device, a lead screw of which the two ends are longitudinally fixed on the bracket through bearings and the bottom ends are connected with the output end of the bevel gear pair, and a transmission wheel II connected with the transmission wheel through a belt; the detection device comprises a mounting plate which is longitudinally fixed on the bracket and is arranged on one side of the lead screw, a plurality of travel switches which are arranged on the mounting plate at certain intervals, a slide block which is in threaded connection with the lead screw and is used for triggering each travel switch, an encoder I which is arranged at the top end of the lead screw, and an encoder II which is fixedly connected with the transmission wheel II. Through adoption of the dynamic simulation test device, the internal hardware-software logic relations in each travel switch and each encoder are reflected truly, wrong detection and missing detection are reduced effectively, and the effectiveness of the travel switches and the encoders are ensured.

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 ...
