Problems solved by technology

[0005] The inventors of the present application found that: simple and additional detection, on the one hand, the additional detection makes the already complicated drum structure more complicated, there are more factors affecting the work of the drum, and the cost is greatly increased, which is not conducive to industrial development and market promotion; on the other hand On the one hand, relatively simple detection is difficult to adapt to the technological development trend of increasingly complex drum structures, and adding detection items cannot really achieve the effect of reducing the time from occurrence to discovery of faults

Embodiment 1

[0024] Such as figure 1 As shown, a drum detection system provided by the present invention includes a drum, and shaft temperature detection elements 21 and vibration detection elements 23 are installed on multiple non-action positions of the drum; 23 Detect the state of the drum during operation.

[0025] There is a lubricating oil circuit 18 in the drum, the shaft temperature detection element 21 is wound on the central shaft 11 in the stator 12, and the vibration detection element 23 is an inertial sensor. The rubber seal 17 is used to connect the outer end cover 16 and the central shaft 11 .

[0026] Thus, the temperature generated by the operation of the inner parts of the drum will be detected by the shaft temperature detection element 21 through heat conduction, and the frequency and amplitude of the drum's working vibration will be detected by the vibration detection element 23 through force conduction, while the frequency and amplitude of temperature and vibration ,...

Embodiment 2

[0037] Such as figure 2 As shown, a drum detection system includes a drum, and shaft temperature detection elements 21 and vibration detection elements 23 are installed on multiple non-action positions of the drum; The state of the time is detected.

[0038] There is a lubricating oil circuit 18 in the drum, the shaft temperature detection element 21 is arranged on the inner surface of the fixed ring of the bearing 14, and the vibration detection element 23 is a vibration switch, which is evenly distributed on the inner surface of the fixed ring of the inner end cover 15. The rubber seal 17 is used to connect the outer end cover 16 and the central shaft 11 .

[0039] This embodiment is more suitable for the use of low-cost rollers. By detecting the contact temperature of the bearing 14 and using the vibration switch to directly detect the vibration of the bearing 14, it is possible to obtain a sufficiently accurate overall internal operation of the roller at the lowest possi...

Embodiment 3

[0052] This embodiment provides a method for determining the position of a sensor in a drum detection system. For the drum, first establish thermal field and vibration field subdivision, both of which adopt the self-adaptive subdivision method of three-dimensional tetrahedron or three-dimensional pentahedron to simulate the heat distribution and vibration distribution during the operation of the drum. After the first subdivision calculation, increase the degrees of freedom in one or more areas with dense heat generation and large vibration fluctuations, use h-p-type finite element subdivision, keep the original subdivision grid in other areas, and perform secondary simulation Heat distribution and vibration distribution. The above step-by-step subdivision method ensures a high convergence speed while improving the subdivision accuracy of the finite element.

Abstract

The invention provides a drum detection system, comprising a drum, on which multiple non-action positions of the drum are equipped with shaft temperature detection elements and vibration detection elements; status is checked. The invention avoids the use of external detection by installing the detection element at a reasonable non-action position, and facilitates the integrated delivery of the drum product, which not only ensures that the cost will not be greatly increased, but also ensures that the detection can find faults as soon as possible.

Description

technical field [0001] The invention relates to a cylinder detection system, which belongs to the technical field of measurement. Background technique [0002] The structure of the rollers in the prior art, especially the permanent magnet direct drive rollers, is becoming more and more complex. For example, a roller lubricating oil system disclosed in patent CN202010796031.8 provides a lubricating oil channel, and the belt conveyor disclosed in patent CN201910585475.4 The temperature-controlled water-cooled drum provides a water-cooling channel. [0003] Although the structure is becoming more and more complex, the core components of the drum have basically not changed substantially. The main purpose of increasing the structure is two: 1. To improve work stability and work efficiency; 2. To reduce the time from occurrence to discovery of faults. [0004] In the prior art, the method of detecting the working state of the drum is generally realized by adding a relatively simp...
