Description

Technical Field

[0001] This utility model relates to the field of vibration damping technology for overhead cranes in electrolytic aluminum production, specifically a vibration damping device applied to the vibration environment of overhead cranes in electrolytic aluminum production. Background Technology

[0002] The overhead crane in aluminum electrolysis production is an important piece of equipment in the aluminum electrolysis workshop. It is mainly used to complete key operations such as electrode replacement, aluminum tapping, busbar transfer, and residual electrode cleaning. Vibration protection of the overhead crane in aluminum electrolysis production is a crucial task. During the aluminum electrolysis production process, the overhead crane will generate significant vibrations due to frequent lifting of heavy objects, running on the track, and mechanical transmission.

[0003] Intelligent lighting fixtures are installed in the electrolytic aluminum production environment to provide illumination for the process. Sensors detect changes in the production environment and send signals to the intelligent lighting fixtures, enabling them to control the lighting and adapt to the needs of the production environment. However, in actual use, vibrations in the electrolytic aluminum workshop are the result of multiple factors, including the operation of large equipment, material handling and loading / unloading, the operation of ventilation and cooling systems, and issues with the workshop's building structure and foundation. This can lead to repeated false triggering of sensors, thus affecting the operation of the intelligent lighting fixtures. Therefore, we propose a vibration damping device for use in the vibration environment of overhead cranes in electrolytic aluminum production. Utility Model Content

[0004] The purpose of this invention is to provide a vibration damping device for use in the vibration environment of overhead cranes in electrolytic aluminum production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vibration damping device for use in the vibration environment of overhead cranes in electrolytic aluminum production, comprising a sensor, wherein the surface of the sensor is provided with a vibration damping structure, the vibration damping structure comprising a fixing plate A, the fixing plate A being fixedly connected to the surface of the sensor, a plurality of threaded rods being fixedly connected to the surface of the fixing plate A, a fixing plate B being threadedly connected to the surface of the plurality of threaded rods, and nuts being threadedly connected to the surface of the threaded rods, and protective pads being glued to the sides of the fixing plate A and the fixing plate B that are close to each other.

[0006] The effect achieved by the above components is as follows: by setting up an anti-vibration structure, the sensor is installed stably, thereby preventing the sensor from shaking due to vibration in the electrolytic aluminum workshop, thus preventing the sensor from being accidentally triggered, and ensuring the normal operation of the intelligent lighting fixtures.

[0007] Preferably, the protective pad is made of rubber.

[0008] The above-mentioned components achieve the following effects: the protective pad is made of rubber, which has good elasticity and cushioning performance. When subjected to vibration, it can effectively absorb and disperse vibration energy, reducing the transmission of vibration to the sensor in the electrolytic aluminum workshop.

[0009] Preferably, two rectangular plates are fixedly connected to the surfaces of both the fixing plate A and the fixing plate B, and two rectangular grooves are formed on the surface of the protective pad, with the dimensions of the rectangular plates matching the dimensions of the rectangular grooves.

[0010] The effect achieved by the above components is as follows: during installation, the rectangular plate is embedded in the rectangular groove, which restricts the displacement of the protective pad and enables it to better play a buffering role. The rectangular plate inserted into the part of the protective pad restricts the deformation of the protective pad, thereby preventing the protective pad from shifting.

[0011] Preferably, triangular plates are fixedly connected to both sides of the rectangular plate.

[0012] The effect achieved by the above components is that the triangular plates on both sides of the rectangular plate further enhance the friction between the rectangular plate and the inner wall of the rectangular groove, thereby improving the stability of the entire shockproof structure.

[0013] Preferably, the surface of the fixing plate B is provided with a detection structure, the detection structure including a rectangular box, the rectangular box being fixedly connected to the surface of the fixing plate B, a pin slidingly passing through the surface of the rectangular box, a rectangular strip being inserted into the inner wall of the rectangular box, a plurality of round holes being opened on the surface of the rectangular strip, the size of the pin being adapted to the size of the round holes, and a frame being fixedly connected to the surface of the fixing plate A, the end of the rectangular strip away from the rectangular box being located within the frame.

[0014] The effect achieved by the above components is as follows: by setting up a detection structure, when vibration occurs in the electrolytic aluminum workshop, if the vibration amplitude causes the rectangular bar to shift, the movement distance of the rectangular bar within the frame can be observed to promptly detect abnormal vibration and take corresponding measures.

[0015] Preferably, the inner wall of the frame is fixedly connected with a plurality of scale marks, and one end of the rectangular strip is fixedly connected with a display frame.

[0016] The effect achieved by the above components is: by observing the positional changes of the scale lines corresponding to the display frame, one can intuitively understand the vibration amplitude of the fixed plate A21 and the fixed plate B22, thereby facilitating the observation of the displacement distance of the sensor vibration.

[0017] Preferably, a spring is fitted onto the arc surface of the pin, and the two ends of the spring are fixedly connected to the pin and the rectangular box, respectively.

[0018] The effect achieved by the above components is that the spring provides a spring force to the pin in the direction of the rectangular bar's circular hole, ensuring that the pin is stably inserted into the circular hole.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This utility model, by setting up an anti-vibration structure, stably installs the sensor on the surface inside the electrolytic aluminum workshop, thereby preventing the sensor from shaking due to vibrations inside the electrolytic aluminum workshop, thus preventing the sensor from being falsely triggered, and ensuring the normal operation of the intelligent lighting fixture.

[0021] By setting up a detection structure, when the sensor is installed, the fixing plate A will move the rectangular bar to be located within the frame. When the sensor vibrates, if the vibration amplitude causes the rectangular bar to shift, the abnormal vibration situation can be detected in time and corresponding measures can be taken by observing the distance the rectangular bar moves within the frame.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-4This utility model provides a technical solution: a vibration damping device for use in the vibration environment of overhead cranes in aluminum electrolysis production. The device includes a sensor 1 with a vibration damping structure 2 on its surface. By setting the vibration damping structure 2, the sensor 1 is stably installed, preventing it from shaking due to vibrations within the aluminum electrolysis workshop, thus preventing accidental triggering and ensuring the normal operation of the intelligent lighting fixtures. A detection structure 3 is provided on the surface of the fixing plate B22. By setting the detection structure 3, when vibration occurs within the aluminum electrolysis workshop, if the vibration amplitude causes displacement of the rectangular bar 33, the device can observe the distance the rectangular bar 33 moves within the frame 35 to promptly detect abnormal vibrations and take appropriate measures.

[0029] Reference Figure 2 and Figure 3 As shown in this embodiment: the shockproof structure 2 includes a fixing plate A21, which is fixedly connected to the surface of the sensor 1. Several threaded rods 23 are fixedly connected to the surface of the fixing plate A21. A fixing plate B22 is threadedly connected to the surface of each of the threaded rods 23. Nuts 24 are threadedly connected to the surface of each threaded rod 23. Protective pads 25 are glued to the sides of the fixing plates A21 and B22 that are close to each other. The protective pads 25 are made of rubber, which has good elasticity and cushioning performance. When subjected to vibration, they can effectively absorb and disperse vibration energy, reducing the transmission of vibration to the sensor 1 within the electrolytic aluminum workshop. Two rectangular plates 26 are fixedly connected to the surfaces of both fixing plates A21 and B22. Two rectangular grooves 27 are formed on the surface of the protective pad 25. The dimensions of the rectangular plates 26 and the rectangular grooves 27 are matched. During installation, the rectangular plates 26 are embedded in the rectangular grooves 27, limiting the displacement of the protective pad 25 and allowing it to better perform its buffering function. The portion of the rectangular plate 26 inserted into the protective pad 25 also limits the deformation of the protective pad 25, thus preventing it from shifting. Triangular plates 28 are fixedly connected to both sides of the rectangular plates 26. These triangular plates 28 further enhance the friction between the rectangular plates 26 and the inner walls of the rectangular grooves 27, improving the stability of the entire shock-absorbing structure 2.

[0030] Reference Figure 4As shown, specifically, the detection structure 3 includes a rectangular box 31, which is fixedly connected to the surface of the fixed plate B22. A pin 32 slides through the surface of the rectangular box 31. A rectangular strip 33 is inserted into the inner wall of the rectangular box 31. Several round holes 34 are formed on the surface of the rectangular strip 33. The size of the pin 32 matches the size of the round holes 34. A frame 35 is fixedly connected to the surface of the fixed plate A21. The end of the rectangular strip 33 away from the rectangular box 31 is located inside the frame 35. Several scale marks 36 are fixedly connected to the inner wall of the frame 35. A display frame 37 is fixedly connected to one end of the rectangular strip 33. By observing the positional changes of the display frame 37 corresponding to the scale marks 36, the vibration amplitude of the sensor 1 can be intuitively understood, thus facilitating the observation of the displacement distance of the fixed plate A21, the fixed plate B22, and the vibration. A spring 38 is fitted onto the arc surface of the pin 32. The two ends of the spring 38 are fixedly connected to the pin 32 and the rectangular box 31, respectively. The spring 38 provides a spring force to the pin 32 in the direction of the round hole 34 of the rectangular strip 33, ensuring that the pin 32 is stably inserted into the round hole 34.

[0031] Working Principle: The shock-absorbing structure 2 reduces the impact of vibration on the sensor 1. The sensor 1 is mounted on the surface of the fixing plate A21, and then the fixing plates A21 and B22 are used to fix the sensor 1 in the electrolytic aluminum production workshop. A protective pad 25 is fixed between the fixing plates A21 and B22 and the installation position, which can effectively reduce the transmission of various vibrations in the electrolytic aluminum workshop to the fixing plates A21 and B22, thereby shockproofing the sensor 1, reducing the damage to the sensor 1 caused by vibration, protecting the internal electronic components and structure of the sensor 1, and extending the service life of the sensor 1. A threaded rod 23 is used to pass through the fixing plate B22 and is tightened with a nut 24. The shock-absorbing structure 2 ensures that the sensor 1 is securely installed in the electrolytic aluminum production workshop. Inside, the protective pad 25 is made of rubber, which has good elasticity and cushioning performance. When subjected to vibration, it can effectively absorb and disperse vibration energy, reducing the transmission of vibration to the sensor 1 in the electrolytic aluminum production workshop. In addition, the rectangular plates 26 on the surfaces of the fixing plates A21 and B22 are adapted to the rectangular grooves 27 on the surface of the protective pad 25. During installation, the rectangular plates 26 are embedded in the rectangular grooves 27, which restricts the displacement of the protective pad 25 and allows it to better play its cushioning role. The rectangular plates 26 inserted into the part of the protective pad 25 restrict the deformation of the protective pad 25, thereby preventing the protective pad 25 from shifting. The triangular plates 28 on both sides of the rectangular plates 26 further enhance the friction between the rectangular plates 26 and the inner wall of the rectangular grooves 27, improving the stability of the entire anti-vibration structure 2.

[0032] The detection structure 3 can monitor the vibration of sensor 1 in real time. A rectangular box 31 is fixed to the surface of the fixing plate B22. A pin 32 passes through the rectangular box 31 and engages with the round hole 34 on the rectangular strip 33 to fix the position of the rectangular strip 33. A spring 38 is sleeved on the arc surface of the pin 32, with its two ends fixedly connected to the pin 32 and the rectangular box 31 respectively. This provides a spring force to the pin 32 towards the round hole 34 of the rectangular strip 33, ensuring that the pin 32 is stably inserted into the round hole 34. When the position of the rectangular strip 33 needs to be adjusted, the pin 32 is pulled out against the spring force of the spring 38. 2. After adjusting the position, release the pin 32. Under the action of the spring 38, the pin 32 is reinserted into the corresponding round hole 34. One end of the rectangular bar 33 is located inside the frame 35. The scale pattern 36 on the inner wall of the frame 35 works in conjunction with the display frame 37 at one end of the rectangular bar 33. When there is vibration in the electrolytic aluminum production workshop, if the vibration amplitude causes the rectangular bar 33 to shift, the vibration amplitude of the fixed plate A21 and fixed plate B22 can be intuitively understood by observing the position change of the scale pattern 36 corresponding to the display frame 37, so as to detect abnormal vibration in time and take corresponding measures.
