Digital master control system of mine hoist

Abstract

The invention relates to a master system of a hoist, in particular to an intelligent digital master system for a hoist and a control method thereof. The intelligent digital master system comprises an absolute value encoder, a zero-position self-locking handle mechanism, a transmission gear and an encoder fixing device, wherein the absolute value encoder fixing device comprises a rotary sphere, a fixed panel and an encoder fixing plate; the fixed panel is vertically and fixedly arranged on one side face of the rotary sphere; the encoder fixing plate is fixedly arranged on the lower bottom surface of the fixed panel; the transmission gear consists of a gear I and a gear II; and bull gear and the zero-position self-locking handle mechanism are coaxially and rotationally arranged at the central position of a rotary panel; the gear II is rotationally arranged on one side of the encoder fixing plate below the gear I; the gear I and the gear II are meshed with each other; and the absolute value encoder is rotationally arranged on the other side of the encoder fixing plate, and is coaxially connected with the gear II. Due to the adoption of a digital master system of the hoist, a digital function is realized through a hoist master.

Description

technical field [0001] The invention relates to a hoist master command system, in particular to an intelligent digital master command system for a hoist, and a control method thereof. Background technique [0002] The existing mine hoist master command control technology is mainly based on analog quantities. Technically, the mine hoist is affected by external environmental factors when it is working. Due to the influence of the external environment, the analog signal is interfered to a certain extent, resulting in inaccurate analog signal transmitted to the programming controller (PLC), which makes the programming When the controller (PLC) calculates the analog quantity, there is an error in the signal, which will cause the hoist to fail to work normally under the working state, which will also cause heavy losses to the user. In addition to easily causing interference to the analog signal during work, it will also cause the analog signal transmitted to the programming contr...

Technically, the mine hoist is affected by external environmental factors when it is working. Due to the influence of the external environment, the analog signal is interfered to a certain extent, resulting in inaccurate analog signal transmitted to the programming controller (PLC), which makes the programming When the controller (PLC) calculates the analog quantity, there is an error in the signal, which will cause the hoist to fail to work normally in the working state, which will also cause heavy losses to the user.

In addition to easily causing interference to the analog signal during work, it will also cause the analog signal transmitted to the programming controller (PLC) to be unstable. The lower and lower requirements do not meet the requirements, so that the operator of the hoist frequently corrects the position of the main command, which will also increase the workload and labor intensity of the operator of the hoist

In order to overcome this unfavorable factor and cause losses and operational errors to users
