Intelligent traction system of self-locking winch

Abstract

The invention relates to an intelligent traction system of a self-locking winch. The intelligent traction system is characterized by comprising a driving mechanism, the self-locking winch, a vertical rope guide wheel, a horizontal guide wheel, a traction steel rope, a hydraulic brake, a vehicle rope lock and a walk-in traction vehicle, wherein the driving mechanism is arranged on the end of a rail and is composed of a lifting motor and a secondary speed reducer, and the self-locking winch is connected with the secondary speed reducer by virtue of a coupling. According to the intelligent traction system, a power source of an internal combustion engine or a motor is replaced, so that materials are automatically aligned quickly, efficiently and accurately in the process that the materials are loaded, unloaded and transferred, the loading efficiency is improved, the loading is automatically controlled, accidents of eccentric weight and end weight caused by inaccurate alignment are reduced, and the intelligent traction system has the advantages of low energy consumption, less pollution and low maintenance cost.

Description

technical field [0001] The invention belongs to the technical field of traction hoisting equipment, in particular to an intelligent traction system of a self-locking winch. Background technique [0002] At present, the loading, unloading and transshipment of products in mine crushing production lines, sintering plants and pelletizing plants generally store materials in a silo with a discharge funnel at the bottom, and transfer transportation equipment (locomotive ) of the walking channel. When loading and unloading, the plug-in plate of the unloading gate is pulled open, and the mineral material is directly unloaded into the cargo compartment of the locomotive. Since the Railway Bureau requires that the loading and unloading should not be biased or end-heavy, the position of the locomotive towed by the locomotive must be within a controllable range when unloading. The alignment process of the locomotive is generally that the operator visually observes the operation of the ...

Problems solved by technology

However, there is a gap between the connecting hooks between the locomotive cars. The inertia of the brakes makes it difficult to accurately control the stop position of the locomotive. Moreover, the experience and status of the operator, and the communication between the operator and the locomotive driver will all affect the accuracy of the alignment and increase the load. The total time of truck unloading

In addition, frequent driving, braking, and idling will cause a huge waste of energy, and diesel locomotives will also cause environmental pollution

Therefore, the traditional method of relying on the alignment of internal combustion engines or electric locomotives cannot meet the requirements of modern enterprises for high efficiency, environmental protection, low energy consumption, and automatic control

[0003] In addition, at present, most of the driving wheels of large-scale mine material reloading traction equipment and cableway transportation hoisting equipment are driven winches in the traditional sense. The traction principle relies on the friction between the friction bushing on the driving wheel and the steel wire rope. Its normal work is based on the premise that the steel rope does not slip on the driving winch, but in fact it is difficult to achieve non-skidding due to the working environment and the anti-skid design, and in order to increase the friction between the steel rope and the driving winch. Increasing the number of strands of the steel rope will cause the steel rope to slide sideways, and the sliding friction will affect the service life of the steel rope and the winch bushing, and the breakage of the steel rope may even lead to accidents

In addition, because the traditional drive winch structure cannot provide a large positive pressure to the steel rope, according to the calculation formula of friction force, the friction force that can be provided, that is, the maximum traction force, is limited. Under the condition of large traction design load, the drive The increase in the diameter of the winch and the diameter of the steel rope increases the contact area, so the volume and weight of the equipment also increase, which is not conducive to controlling manufacturing costs and subsequent equipment maintenance
