Flexible rail guide device of hoisting container and dynamic characteristic detection method thereof

Abstract

The invention discloses a flexible rail guide device of a hoisting container and a dynamic characteristic detection method thereof. The device comprises a wireless receiving device, an industrial personal computer, and a guide device fixed in the hoisting container. A power generation device and a detection device are arranged on the guide device. A wireless transmitting device is arranged in thedetection device. The guide device is arranged at the upper side and the lower side of the hoisting container. The upper and lower primary and secondary guide wheels of the guide device compress the flexible rail to move up and down. The included angle of the upper and lower primary and secondary guide wheels of the guide device is controlled according to the actual installation condition. A friction wheel of the power generation device compresses the primary guide wheel. The motion of the hoisting container drives the guide wheel to rotate so as to drive the friction wheel to drive the powergeneration device to generate power and store the power in a storage cell. An axial coder of the detection device connected with the other side of the friction wheel real-time detects the dynamic characteristic of the guide wheel. The wireless transmitting device transmits the signal to a wellhead in real time and the signal is received by the wireless receiving device of the wellhead, and then the industrial personal computer analyzes the signal in real time to determine the dynamic characteristic of the guide process.

Description

technical field [0001] The invention relates to a flexible guide rail guide device for a hoisting container and a dynamic characteristic detection method thereof, and is especially suitable for guiding and dynamic characteristic detection of a hoisting container (cage, skip, mine elevator car) of a mine wire rope flexible guide rail. Background technique [0002] At present, the flexible guide rail is mainly the tank guide rail system based on the wire rope, and the wire rope guide rail system is mainly used in the hoisting system of the mine hoisting container (cage, skip) in China. As a mine hoist cage and skip hoisting system based on flexible guide rails, the tank lugs with inner polyethylene or polyurethane or polyurethane sliding sleeves are mainly used to guide on flexible guide rails (wire ropes). During the high-speed operation of the lifting container, a high-speed sliding friction state is formed between the polyethylene or polyurethane sliding sleeve and the flex...

AI Technical Summary

Problems solved by technology

[0007] This method of monitoring the running state of the hoist mainly has the following defects: the tension sensor has low sensitivity and reliability, the strain sensor is easily disturbed by external factors, the connection between the two ends of the tension sensor and the hoisting wire rope will aggravate the fatigue wear of the wire rope, and the oil pressure sensor only It is suitable for the occasion of lifting the steel wire rope hydraulic balance device; the battery needs to be replaced regularly, and the installation and maintenance of the sensor are inconvenient

[0009] (1) At present, there are mainly the following defects in the guidance of tank lugs with inner polyethylene or polyurethane sliding sleeves: the material of polyethylene or polyurethane sliding sleeves wears rapidly during high-speed operation, and is even torn and peeled off. In severe cases, the sliding sleeves fall off. This results in frequent replacement of tank lugs, while the flexible guide rail is easily damaged and has a short service life

[0010] (2) The detection of the dynamic characteristics of the lifting container mainly detects the tension of the steel wire rope. The method mainly has the following defects: the sensitivity and reliability of the tension sensor are low, the tension sensor will cause the fatigue fracture of the steel wire rope, and the oil pressure sensor is only suitable for the hydraulic balance of the lifting steel wire rope. The occasion of the device; the maintenance of the detection system is difficult; the battery power supply scheme needs to replace the battery regularly, which is inconvenient to maintain; the existing sensors have problems such as high cost, low sensitivity, and damage to the wire rope
