Abstract
Description
Technical Field
[0001] This application relates to the field of intelligent detection technology for mechanical equipment operating conditions, and in particular to a rapid installation device for preventing the temperature and vibration sensor of a vibrating screen from falling off. Background Technology
[0002] Vibrating screens play a crucial role in coal and mineral processing. Their screening capacity improves the accuracy and stability of coal preparation. As one of the most important components in the entire coal washing process, the condition of the vibrating screen directly affects the operation of the entire system. When a vibrating screen malfunctions, it impacts the system's washing efficiency and quality.
[0003] Vibrating screens have been used in China for many years, and the products are very mature, with standardized components from various manufacturers. However, vibrating screens were not designed with pre-defined locations for intelligent upgrades to install sensors, making sensor installation and replacement extremely inconvenient. The secure mounting of the sensors directly affects the accuracy of monitoring the vibrating screen's condition. Furthermore, as critical components with high prices, if a sensor detaches from the vibrating screen exciter, it will be carried to the next process along with the material on the screen, making it impossible to retrieve and resulting in economic losses and increased operating costs. Utility Model Content
[0004] Therefore, it is necessary to provide a rapid installation device for preventing the temperature and vibration sensors on a vibrating screen from falling off, which can quickly replace the temperature and vibration sensors on the vibrating screen and prevent them from falling off, in order to address the above-mentioned technical problems.
[0005] This application provides a quick-installation device for preventing the temperature vibration sensor from falling off a vibrating screen. The device is used to install the temperature vibration sensor on the vibrating screen. The device includes a hollow sleeve, wherein the side of the hollow sleeve is provided with a through-hole. The cross-sectional area inside the hollow sleeve is not less than the cross-sectional area of the temperature vibration sensor. When the temperature vibration sensor is placed inside the hollow sleeve, a limiting device corresponding to the through-hole limits and fixes the temperature vibration sensor through the through-hole in a direction pointing towards the center of the temperature vibration sensor.
[0006] In one embodiment, the temperature vibration sensor has a housing at its bottom with a connecting through hole. The shape of the cross-section inside the hollow sleeve corresponds to the bottom housing of the temperature vibration sensor. The area of the cross-section inside the hollow sleeve is not less than the cross-sectional area of the bottom housing of the temperature vibration sensor, and the through connecting through hole of the hollow sleeve corresponds to the connecting through hole on the bottom housing of the temperature vibration sensor.
[0007] In one embodiment, the device further includes a protrusion connected to the hollow sleeve. The protrusion has a through-hole for fixing. When the hollow sleeve and the protrusion are placed on the vibrating screen, the fixing device corresponding to the through-hole for fixing fixes the hollow sleeve and the protrusion to the vibrating screen through the through-hole for fixing fix.
[0008] In one embodiment, there are two through-holes, which are respectively located on two parallel sides of the hollow sleeve.
[0009] In one embodiment, the through-hole is a threaded through-hole, and the limiting device corresponding to the through-hole is a threaded pin.
[0010] In one embodiment, an elastic retaining ring is provided between the threaded pin and the threaded through hole for locking.
[0011] In one embodiment, the height of the protrusion is not higher than the height of the hollow sleeve.
[0012] In one embodiment, there are two protrusions, which are respectively connected to the two sides of the hollow sleeve that are not provided with through-holes.
[0013] In one embodiment, the line connecting the center points of the two sides of the hollow sleeve connected to the protrusion and the line connecting the center points of the two sides of the hollow sleeve with the through-hole are perpendicular to each other.
[0014] The aforementioned rapid installation device for preventing the temperature and vibration sensor of the vibrating screen from falling off utilizes a through-hole connection on the side of a hollow sleeve. The cross-sectional area inside the hollow sleeve is not less than the cross-sectional area of the temperature and vibration sensor. When the temperature and vibration sensor is placed inside the hollow sleeve, a limiting device corresponding to the through-hole fixes the sensor along the direction pointing towards the center of the sensor. By utilizing the structural characteristics of the screen plate itself, the device enables rapid and non-destructive installation and removal of the sensor, avoiding the problems of insecure installation and sensor loss caused by using ordinary adhesive bonding processes or machining the installation position on the vibrating screen body.

[0020] This application relates to the field of intelligent detection of the working conditions of medium-sized mechanical equipment in the production process of industries such as coal and non-coal mines, and in particular to a rapid installation device for temperature and vibration sensors of vibrating screens, which is used for intelligent diagnosis of the working status of vibrating screens and quick replacement of temperature and vibration sensors.
[0021] Vibrating screens play a crucial role in coal and mineral processing. In coal preparation, they are one of the key pieces of equipment in the entire coal washing process. They are primarily used for classifying and screening coal and other minerals, separating coal particles of different sizes. Materials passing through vibrating screens can be efficiently classified and dewatered.
[0022] The screening capacity of vibrating screens improves the accuracy and stability of coal preparation. They can effectively classify coal according to different particle size grades, meeting the needs of various washing processes and products. Simultaneously, vibrating screens can improve coal preparation efficiency and reduce production costs. Furthermore, the reliable and stable operation of vibrating screens ensures the continuity of coal preparation operations, avoiding production interruptions due to equipment failure. Its stable operation is crucial for the smooth operation of the entire coal preparation process. In conclusion, vibrating screens are indispensable in the field of coal preparation, providing a solid guarantee for efficient coal separation and quality improvement.
[0023] As one of the most crucial components in the entire coal washing process, the condition of the vibrating screen directly impacts the operation of the entire system. When the vibrating screen malfunctions, it affects the washing efficiency and quality. Therefore, in daily production, inspectors need to check the condition of the vibrating screen daily, or monitor its status using sensors installed on the screen. Currently, vibrating screens have been used in China for many years, and the products are very mature, with standardized components from various manufacturers. However, vibrating screens were not designed with pre-defined locations for intelligent upgrades to install sensors, making sensor installation and replacement very inconvenient. The secure mounting of the sensors directly affects the accuracy of monitoring the vibrating screen's condition. Furthermore, as high-priced critical components, if sensors detach from the vibrating screen exciter, they will enter the next process with the material on the screen, making them irretrievable, resulting in economic losses and increased operating costs.
[0024] Current solutions include using glue to bond the sensor to the vibrating screen, machining threaded holes at the sensor installation location on the vibrating screen and installing with bolts, and fixing the sensor to the vibrating screen via a sensor connection base. Among these, the method of using glue to bond the sensor to the vibrating screen has the advantage of not needing to damage the screen structure and is simple to install. The disadvantages include (1) the glue bonding curing time is long, and the equipment needs to be stopped for a long time to fall off or replace it, which is difficult to meet the daily inspection, maintenance and replacement needs; (2) if the bonding is not firm, the sensor is easy to fall off or be lost; (3) the vibrating screen is a dynamic vibration device, and as the equipment runs for a long time, the glue-bonded sensor will gradually loosen. The loosening of the glue bonding is not easy to detect, and after loosening, it will quickly lead to the sensor falling off or being lost. The method of machining threaded holes and using bolts to install sensors on vibrating screens has the advantages of simple and convenient installation and replacement; the disadvantages include (1) the small size of temperature vibration sensors is their biggest appearance feature, and large bolts cannot be used to fix them. Generally, only bolts smaller than M6 can meet the sensor fixing requirements. Machining such small threaded holes on vibrating screens will cause the threads on the screen body to be quickly damaged by the vibration of the vibrating screen and the corrosion of the washing water, requiring the threaded holes to be machined again, which will damage the screen body and greatly affect the service life of the vibrating screen; (2) different sensors support different threaded hole specifications, and the threaded holes need to be re-machined when replacing other sensors, which will affect the service life of the vibrating screen. The method of fixing the sensor to the vibrating screen by connecting the sensor to the base has the advantages of convenient replacement and disassembly; the disadvantages include (1) there is no universal mounting base. Bases purchased on the market can be used but are not compatible, which can easily lead to sensor damage; (2) it is generally suitable for high-frequency static vibration equipment such as motors and shaft seats. When used on low-frequency dynamic vibration equipment such as vibrating screens, the sensor is prone to falling off or being lost due to loose threads, which increases maintenance time and production costs.
[0025] Based on the defects and shortcomings of the above-mentioned traditional technologies, this utility model realizes the rapid replacement and anti-fall-off protection of the temperature and vibration sensor on the vibrating screen through a quick installation device to prevent the temperature and vibration sensor from falling off.
[0026] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0027] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0030] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
[0031] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.
[0032] In one exemplary embodiment, this application includes a metal base consisting of a hollow sleeve and two protrusions, wherein the metal base, threaded pins, and elastic retaining rings are all made of 316L stainless steel, which can adapt to different process vibrating screens and has strong corrosion resistance.
[0033] For example, conventional adhesive sensors are glued to the vibrating screen body or vibrator. Replacing the sensor is difficult, time-consuming, and labor-intensive, and it easily damages the sensor, rendering it unusable. Installing sensors in small threaded holes on the vibrating screen is also problematic. Since the flushing water in coal washing plants is recycled and corrosive, the threads in these holes quickly wear out, requiring re-machining and affecting the screen's lifespan. Furthermore, the sensors are valuable; if they loosen and detach, they can mix with materials and enter subsequent processes, making them difficult to retrieve. Frequent detachment significantly increases coal washing costs. However, using a rapid-installation anti-detachment device for vibrating screen temperature and vibration sensors avoids these problems. When installing the rapid installation device for preventing the temperature and vibration sensor from falling off the vibrating screen, the first step is to drill holes at the installation location on the screen body in advance, and then use bolts or Hooke bolts to fix the device to the vibrating screen body. The second step is to place the sensor into the hollow sleeve of the device, aligning the side of the sensor base (bottom sleeve) with the connecting through hole with the side of the hollow sleeve with the through connecting through hole. After placing the sensor in place, use threaded pins to secure the sensor and the device together. The third step is to install the elastic retaining ring, snapping it between the threaded pin and the threaded through hole, completing the sensor installation. To replace the sensor, simply remove the elastic retaining ring and the threaded pin.
[0034] Experimental data demonstrates that the rapid installation device for preventing the temperature and vibration sensors of vibrating screens from falling off reduces sensor loosening issues by over 99% and the resulting sensor loss. In terms of performance, the device facilitates easy installation and disassembly, reducing sensor replacement time to 5 minutes and sensor removal time to 2 minutes, significantly improving sensor replacement efficiency. It standardizes sensor installation, achieving 100% accuracy, enhancing sensor data consistency, and virtually eliminating the problem of sensor loss due to detachment on vibrating screens, thus saving on sensor procurement costs. Simultaneously, it reduces maintenance time and improves production management efficiency. The rapid installation device for preventing the temperature and vibration sensors of vibrating screens also boasts advantages such as simple processing technology and low cost.
[0035] In an exemplary embodiment, the vibrating screen temperature sensor anti-detachment quick-installation device, after installing the sensor, is shown in Figures 1(a) and 1(b). The sensor 1 is installed in the vibrating screen temperature sensor anti-detachment quick-installation device 2 and connected by a threaded pin 3 and an elastic retaining ring 4. Further, the oblique view of the vibrating screen temperature sensor anti-detachment quick-installation device is shown below. Figure 2 As shown; Top view of the vibrating screen temperature sensor anti-detachment quick installation device. Figure 3 As shown; Front view of the vibrating screen temperature sensor anti-fall-off quick installation device. Figure 4As shown, the rapid installation device for preventing the temperature and vibration sensor of the vibrating screen from falling off includes a hollow sleeve 201, a protrusion 202, a through-hole 203, and a through-fixing through-hole 204. Specifically, the hollow sleeve 201 has a through-hole 203 on its side, and the area of the internal cross-section of the hollow sleeve 201 is not less than the cross-sectional area of the temperature and vibration sensor 1. When the temperature and vibration sensor 1 is placed inside the hollow sleeve 201, a limiting device corresponding to the through-hole 203 limits and fixes the temperature and vibration sensor 1 through the through-hole 203 in a direction pointing towards the center of the temperature and vibration sensor 1. Further, the bottom of the temperature and vibration sensor 1 has a shell with a connecting through-hole. The shape of the internal cross-section of the hollow sleeve 201 corresponds to the bottom shell of the temperature and vibration sensor 1, and the area of the internal cross-section of the hollow sleeve 201 is not less than the cross-sectional area of the bottom shell of the temperature and vibration sensor 1. The through-hole of the hollow sleeve 201 corresponds to the connecting through-hole on the bottom shell of the temperature and vibration sensor 1. Furthermore, the protrusion 202 is connected to the hollow sleeve 201. The protrusion 202 is provided with a through-hole 204. When the hollow sleeve 201 and the protrusion 202 are placed on the vibrating screen, the fixing device corresponding to the through-hole 204 fixes the hollow sleeve 201 and the protrusion 202 to the vibrating screen through the through-hole 204. There are two through-holes 203, which are respectively set on the two parallel sides of the hollow sleeve 201. The through-hole 203 is a threaded through hole, and the limiting device corresponding to the through-hole 203 is a threaded pin 3. An elastic retaining ring 4 is provided between the threaded pin 3 and the threaded through hole for locking. The height of the protrusion 202 is not higher than the height of the hollow sleeve 201. There are two protrusions 202, which are respectively connected to the two sides of the hollow sleeve 201 where the through-hole 203 is not provided. The line connecting the center points of the two sides of the hollow sleeve 201 connected to the protrusion 202 is perpendicular to the line connecting the center points of the two sides of the hollow sleeve 201 with the through hole 203. For example, the direction in which the threaded pin is driven into the threaded through hole is perpendicular to the side with the threaded through hole on the other side.
[0036] This application provides a quick-installation device for the temperature and vibration sensor of a vibrating screen, designed for rapid replacement and prevention of loss. All components of the mounting bracket are made of 316L stainless steel, ensuring sufficient wear and corrosion resistance to adapt to the working environment of vibrating screens in different process stages of coal preparation plants. The installation steps include: First, installing the temperature and vibration sensor mounting device onto the vibrating screen body and securing it with bolts; second, installing the sensor into the device's fixed position and securing it with pins; third, installing the elastic retaining ring into place.
[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
