Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of monitoring devices, and particularly relates to a vibration monitoring device for a steel rail shaft guide. Background Art
[0002] The main shaft guide adopts a steel rail shaft guide. This shaft guide mode is greatly affected by the mining pressure in the mine production. When the hoisting container runs at high speed in the main shaft shaft, the sliding shaft guides on both sides of the skip have rigid friction with the steel rail shaft guide. The high-speed operation, frequent lifting, and heavy load all promote this rigid friction to continuously impact the shaft guides on both sides. Moreover, the aging main shaft shaft environment has a very high humidity and is the air inlet in the underground, so the oxidation and corrosion of the shaft guide and its attached facilities are very serious, especially for the exposed threads of the bolts of the shaft guide clips.
[0003] As Figure 4 shown, the relationship between the shaft guide clip 6 and the shaft guide notch plate 9 complements each other. The loosening of the shaft guide clip 6 will cause the shaft guide 5 to move in the vertical direction along the shaft guide beam 8, thus wearing the shaft guide notch plate 9. The wear and open welding of the shaft guide notch plate 9 will cause the shaft guide 5 to move along the direction of the shaft guide beam 8, resulting in the loosening of the shaft guide clip 6, and then a series of problems of the shaft guide 5 will occur. For example, the distance between two parallel shaft guides 5 will change, the joints of the shaft guide 5 will be misaligned, the bolts 7 of the shaft guide clip will be loosened, resulting in the failure of the shaft guide clip 6, and the shaft guide notch plate 9 will be open welded due to long-term impact. When the above situations occur, hoisting accidents are very likely to occur, which also means that the dynamic monitoring and maintenance tasks of the shaft guide are of great significance.
[0004] To prevent serious hoisting accidents caused by problems such as distance change, misalignment, bolt loosening, and open welding, therefore, it is very necessary to design a vibration monitoring device for the steel rail shaft guide of the main shaft hoist. Content of the Utility Model

Specific embodiments
[0024] Such as Figure 1 As shown, the present utility model includes a vibration detection component for detecting the vibration of the guide, the detection signal output port of the vibration detection component is connected to the detection signal input port of the data signal acquisition part, the detection signal output port of the data signal acquisition part is connected to the detection signal input port of the controller, the alarm control signal output port of the controller is connected to the alarm control signal input port of the alarm, and the signal transmission port of the controller is connected to the signal transmission port of the monitoring computer.
[0025] The vibration detection component includes a horizontal vibration detection component for detecting the horizontal vibration of the guide and a vertical vibration detection component for detecting the vertical vibration of the guide.
[0026] The horizontal vibration detection component includes four horizontal vibration sensors, and the vertical vibration detection component includes four vertical vibration sensors.
[0027] The four horizontal vibration sensors are horizontally magnetically adsorbed on the guide beam 6, and the four vertical vibration sensors are vertically magnetically adsorbed on the guide beam 6.
[0028] The guide 5 uses 43 kg / m steel rails, each with a length of 12.50 m, and is fixed by guide clips 6.
[0029] The guide beam 8 is ninety-three layers, as Figure 3As shown in the figure, four horizontal vibration sensors are horizontally magnetically adsorbed on the 18th layer of cage guides 4, the 38th layer of cage guides 3, the 58th layer of cage guides 2, and the 78th layer of cage guides 1 from top to bottom. Four vertical vibration sensors are vertically magnetically adsorbed on the 18th layer of cage guides 4, the 38th layer of cage guides 3, the 58th layer of cage guides 2, and the 78th layer of cage guides 1 from top to bottom. The cage guides 6 are arranged horizontally, and the cage guides 5 are arranged vertically. First, the cage guides 6 are set, and then the cage guides 5 are set on the cage guides 6.
[0030] Through the daily inspection of the cage guides 5 by the cage inspection workers, it is analyzed that the cage guides 5 are worn faster at the upper and lower wellheads. Based on these two weak points, the entire cage guides 5 are divided into four parts. That is, by placing vibration sensors every twenty layers, it can ensure the uniform distribution of monitoring points in the entire shaft cage guide system, which helps to comprehensively capture and evaluate the vibration of the cage guide system, so as to timely discover possible problems or potential hazards. The vertical arrangement method can directly monitor the vibration of the cage guides 5 in the vertical direction, forming a complement to the horizontal vibration sensors and providing more comprehensive monitoring data.

The GZC20 mine intrinsically safe vibration sensors can be used in places with explosive gas mixtures; can work normally in the temperature range of -30°C to 80°C; and have a magnetic adsorption design, which is convenient for installation and maintenance, and is also conducive to the stable fixation of the sensors in the vibration environment. With its explosion-proof design, wide temperature adaptability, and magnetic adsorption installation structure characteristics, the GZC20 mine intrinsically safe vibration sensors can operate stably in harsh environments, ensuring the accuracy and reliability of monitoring.
[0034] The data signal acquisition part uses a VM3209C module. The VM3209C module performs protocol conversion on the collected vibration signals and converts them into data in the Profinet protocol for communication with the PLC. The VM3209C module can communicate with different brands and models of PLCs; can ensure the real-time transmission and processing of vibration data; and realizes remote data acquisition and monitoring.
