Description

Technical Field

[0001] This utility model relates to the field of mining machinery, and in particular to a vibration damping platform system for a crusher and a crusher having said vibration damping platform system. Background Technology

[0002] The vibration damping platform system is a key component for ensuring the stable operation of a multi-cylinder hydraulic cone crusher. During operation of the mining crushing production line, the load generated by the material being crushed changes in real time with the feed rate. This variable load is transmitted to the vibration damping platform system. The vibration damping device absorbs the vibration caused by the variable load while maintaining the platform's levelness, thus affecting the power consumption, steel consumption, failure rate, and production efficiency of the multi-cylinder hydraulic cone crusher.

[0003] In the existing technology, the vibration damping platform system has the following problems: the vibration damping device may experience overload or fatigue aging, making it impossible to predict the tilt of the vibration damping platform; when the multi-cylinder hydraulic cone crusher is running, its offset is prone to exceed the value in the low point direction, resulting in a decrease in its processing capacity and finished product rate. At the same time, the copper sleeve of the vibration damping device will wear abnormally, causing the lubricating oil temperature to rise, which will lead to alarm shutdown and greatly reduce production efficiency.

Detailed Implementation

[0022] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of this utility model. Based on the description of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0023] like Figures 1 to 4 As shown, one embodiment of this application provides a vibration damping platform system for a crusher, including a main platform 3 for supporting the crusher host 6, a plurality of elastic vibration damping devices 5 respectively disposed at multiple positions below the main platform 3, a displacement sensing device 2 installed on the main platform 3, and a processor 21 communicatively connected to the displacement sensing device 2; the displacement sensing device 2 is used to detect the elastic deformation of the vibration damping device 5 under the pressure of the crusher when the crusher is working, and the processor 21 is used to determine the tilt state of the main platform 3 based on the elastic deformation of the vibration damping device 5.

[0024] like Figure 2As shown, the main platform 1 includes an upper base plate 31, a lower base plate 33, and a support plate 32. The upper base plate 31 is used to support the crusher host 6. Multiple support plates 32 are supported between the upper base plate 31 and the lower base plate 33. The maximum stress point of the support plate 32 is designed with a release hole, which can improve its structural strength. The upper base plate 31, the lower base plate 33, and the support plate 32 are all made of steel plates. The selection of steel plates enhances its overall rigidity and reduces its weight and deformation. The support plate 32 is connected to the upper base plate 31 and the lower base plate 33 by welding, which improves the welding performance, avoids cracking under stress, and further optimizes the overall structure. The main platform 3 also includes a surrounding plate 34, which is used to prevent the vibration damping device 5 from shifting when subjected to load changes during crusher operation. The surrounding plate 34 is connected to the bottom of the lower base plate 33, so that the entire main platform 3 is connected to form a welded component by cutting and welding sheet metal. Compared with the profile cutting and welding method used in the prior art between the upper base plate 31, the lower base plate 33 and the support plate 32, this method avoids the risk of profile cutting reducing its strength, reduces the amount of material used, and ensures the parallelism of the mounting surface of the vibration damping platform system, thus improving the stability of the main platform 3. In a further embodiment, the steel plates used for the upper base plate 31, the lower base plate 33 and the support plate 32 are preferably high-strength low-alloy structural steel.

[0025] like Figure 3 As shown, the vibration damping device 5 includes an elastic damping component 52, an upper pad 51, and a lower pad 53. The upper pad 51 and the lower pad 53 are respectively disposed on both sides of the vibration damping component 52. The upper pad 51 is fixedly connected to the lower base plate 33 of the main platform 3. The vibration damping component 52 is preferably equipped with a cylindrical enclosure 34 for protection, and its interior includes a damper, which has a high load-bearing capacity, significantly increasing the load-bearing capacity in both the vertical and horizontal directions. The vibration damping device 5 is preferably a heavy-duty elastic vibration damper with a damper, which has stronger torsional resistance, thereby extending its service life and improving the stability and reliability of the vibration damping device 5 and the entire vibration damping platform system.

[0026] like Figure 4As shown, the displacement sensing device 2 is installed on the main platform 3. When the crusher body 6 is working, the crusher will apply variable loads to various positions of the main platform 3, causing the damping components 52 of the multiple damping devices 5 distributed below the main platform 3 to undergo corresponding compression under the load, resulting in corresponding displacements in the vertical direction of various areas of the main platform 3. At this time, the displacement sensing device 2 can be used to detect the amount of displacement change of the main platform 3 in the vertical direction. The detected data is accurate and reliable. Furthermore, the displacement sensing device 2 is communicatively connected to the processor 21, and can upload the detected data to the processor 21 in real time for calculation. Based on the data from the displacement sensing device 2, the processor 21 calculates the compression amount of the damping components 52 of each damping device 5, and calculates whether the compression amount is within the allowable range. Furthermore, based on whether the compression amounts of each damping component 52 are equal at the same time, it can be determined whether the main platform 3 has tilted.

[0027] Specifically, when the crusher host 6 is working, the main platform 3 bears the load generated by the crusher host 6. This load value is within a certain range, and the main platform 3 uniformly converts the load value into the vertical downward direction, the horizontal direction, and the circumferential direction. In a static state, the main platform 3 is unloaded. At this time, the displacement sensing device 2 can obtain the initial displacement before the load, and the vibration damping device 5 is also in its initial state, allowing direct measurement of the initial compression value of the vibration damping component 52 of the vibration damping device 5. When the crusher is operating, the load value changes dynamically with the working load of the crusher. At this time, the displacement sensing device 2 can also obtain the final displacement after the load, but the final compression value of the vibration damping component 52 of the vibration damping device 5 is variable and cannot be measured. Therefore, the displacement sensing device 2 uploads the obtained data to the processor 21. The processor 21 calculates the final compression value of the vibration damping component 52 of the vibration damping device 5 according to the program, and judges the tilt state of the main platform 3 based on whether the final compression value is within a reasonable range. This process improves the intelligence of the vibration damping platform system, increases its reliability, reduces troubleshooting time, and extends the service life of the crusher.

[0028] The specific method for processor 21 to calculate the compression amount of vibration damping device 52 may include the following steps: For each vibration damping device 52, the initial displacement X1 and final displacement X2 of the vibration damping device 52 sensed by displacement sensing device 2 are obtained. At the same time, the initial value of the compression amount of the vibration damping component 52 of the vibration damping device 5 is set to S1, and the final value of the compression amount of the vibration damping component 52 is set to S2. According to the equation X1-X2=S1-S2, the final value of the compression amount S2 of the vibration damping device 5 is calculated, and it is further determined whether it is within the allowable compression amount range. Thus, the tilt state of the main platform 3 is judged based on whether the compression amounts of each vibration damping component 52 are equal at the same time.

[0029] like Figure 1As shown, the vibration damping platform system also includes a connector 4. The upper pad 51 of the vibration damping device 5 is fixed to the main platform 3 via the connector 4, connecting the vibration damping device 5 to the main platform 3. Compared with the welding method of the prior art, this avoids the heat effect of welding, shortens the replacement time of parts, reduces power consumption and steel consumption, and extends production efficiency. In addition, the vibration damping platform system also includes a junction box 1, which is installed on the crusher host 6 and is used to connect the crusher to the power supply.

[0030] In summary, the vibration damping platform system provided by the above embodiments of this utility model includes a main platform 3, a vibration damping device 5, a displacement sensing device 2, and a connector 4. The main platform 3 has been optimized; its upper base plate 31, lower base plate 33, and support plate 32 are all made of high-strength low-alloy structural steel, connected by a plate cutting and welding method, improving structural rationality, enhancing welding performance, and increasing overall rigidity. The vibration damping device 5 has also been optimized, employing a heavy-duty elastic vibration damper with a damper, which significantly increases load-bearing capacity and service life, improving the stability and reliability of the vibration damping platform system. The vibration damping platform system also includes a displacement sensing device 2, used to detect the elastic deformation of the main platform 3 under the pressure of the crusher, and communicating with the processor 21 to calculate the compression of the vibration damping device 5 and determine the tilt state of the main platform 3. The displacement sensing device 2 provides real-time data feedback to the system, improving the overall level of intelligent technology application. In addition, in this case, the main platform 3 and the vibration damping device 5 are connected by connector 4. Compared with the welding method in the prior art, the welding effect can be avoided and the wear and tear of replacement parts can be reduced.

[0031] like Figure 1 As shown, another embodiment of this utility model provides a crusher, including a crusher host 6 and the aforementioned vibration damping platform system. The crusher host 6 is supported on the main platform 3 of the vibration damping platform system. The main platform 3 of the vibration damping platform system bears and transmits the load of the crusher host 6. The vibration damping device 5 absorbs the variable load of the crusher host 6, ensuring the stable operation of the crusher host 6, thereby improving the production efficiency of the crusher and extending its service life. In addition, the crusher also includes a motor 7, which is also supported on the main platform 3 and provides energy to the crusher.

[0032] In summary, the crusher provided by the above-described embodiments of this utility model includes a crusher host 6 and the aforementioned vibration damping platform system. The crusher host 6 is mounted on the main platform 3 of the vibration damping platform system. The vibration damping platform system transmits and absorbs the variable loads during the movement of the crusher host, ensuring the stable operation and high production efficiency of the crusher host 6. The main platform 3 of the vibration damping platform system adopts a connection method of high-strength steel and plate material cutting and welding, increasing the overall strength. The vibration damping device 5 adopts an elastic vibration damper with a damper, further buffering the load on the crusher host 6. The displacement sensing device 2 adopts a non-contact radar wave detection ranging sensor, which can reliably feedback relevant data, reducing troubleshooting time and extending the service life of the crusher. The optimization of the above components further ensures the stability of the crusher's operation, makes the crusher's production efficiency higher, reduces resource and material consumption, and extends the service life of the crusher.

[0033] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto.
