Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to an intelligent shock-absorbing base for a mining vibrating screen. Background Technology

[0002] In the mining production system, the mining vibrating screen is the core equipment for ore screening operations, and its connection structure with the shock-absorbing base is crucial.

[0003] The mining environment is inherently harsh. Factors such as ore impact, dust, and damp erosion continuously affect the connection between the vibrating screen and the shock-absorbing base. Although the traditional bolt connection method can theoretically achieve fixation, in actual operation, when repairing or replacing the vibrating screen, operators need to spend a lot of time tightening each bolt one by one. When the equipment is installed in batches, the consumption of manpower and time costs is even more staggering. The process of disassembling bolts is equally difficult. Corroded bolts are difficult to loosen, and violent disassembly may damage the equipment itself, resulting in excessive downtime and severely delaying the mine's production progress, which in turn affects the coordinated operation of subsequent ore processing, transportation and other links.

The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0028] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0029] Example 1: Reference Figure 1-4 A typical installation example for standard operations (positioning slide + rotating threaded rod sleeve)

[0030] Suitable for general mining operations where the vibrating screen has a stable load and a normal vibration frequency, the positioning component uses a common positioning slide, which slides in conjunction with the positioning slide groove of the mounting base. Initial positioning is achieved using a conical slide groove. The fixed slider is driven to move by rotating the threaded sleeve, thus clamping and limiting the positioning slide. During installation, the positioning slide quickly slides into the groove, and rotating the threaded sleeve locks the slider in place. The operation is simple, the structure is low-cost and easy to install, and it can meet the stability requirements of daily mining screening operations, making it suitable for use in small and medium-sized mines.

[0031] Example 2: Reference Figure 5 Example of stable installation in high vibration environment (magnetic positioning slide)

[0032] For the high-frequency, high-intensity vibration conditions of vibrating screens in large mines, a magnetic positioning slide and trapezoidal fixed slider are used to enhance stability. The positioning component is replaced with a magnetic positioning slide, which strongly attracts the magnetic seat in the positioning slide groove to ensure fast and accurate positioning. The rotating threaded sleeve is thickened to provide greater clamping force. Under strong vibration, the magnetic positioning prevents the slide from shifting, effectively avoiding loosening of the vibrating screen and ensuring long-term stable operation of the equipment.

[0033] Furthermore, when using this device, when it is necessary to install the vibrating screen onto the base, first align the vibrating screen connecting seat 4 at the bottom of the vibrating screen with the mounting seat 3, so that the positioning part 13 (if it is a magnetic positioning slide 16, it can be pre-fixed by magnetic attraction) is inserted along the positioning slide groove 6. At this time, the protrusion on the outer wall of the positioning part 13 slides and engages with the conical slide groove 15 of the positioning slide groove 6. The installation deviation is automatically corrected by the guiding effect of the conical surface, ensuring that the positioning part 13 is accurately embedded in the groove, achieving preliminary positioning, and preventing the vibrating screen from shifting during installation. After the preliminary positioning is completed in the locking and fixing stage, the fixing slider 5 is moved along the first fixing slider groove 11 towards the fixing... The sliding block 6 slides inside the positioning slot 6, and its end is embedded in the second fixed slider groove 14 of the positioning member 13. Then, the rotating blocks 7 on both sides of the mounting base 3 are rotated, which drives the rotating threaded rod sleeve 17 to rotate. Since the rotating threaded rod 9 is threadedly connected to the rotating threaded rod sleeve 17, when the rotating threaded rod sleeve 17 rotates, it drives the rotating threaded rod 9 to extend axially, pushing the slider 8 to move along the first slider groove 10 towards the second slider groove 12, until the end of the slider 8 is completely embedded in the second slider groove 12. At this time, the clamping effect between the slider 8 and the second slider groove 12 restricts the retraction of the fixed slider 5, ensuring the stability of the connection structure. Then, the vibration damping operation begins. When the vibrating screen is in operation, high-frequency vibration is transmitted to the mounting base 3 through the vibrating screen connecting seat 4, and then from the mounting base 3 to the damping mechanism 2. The spring dampers in the damping mechanism 2 absorb vibration energy through elastic deformation, reducing the transmission of vibration to the support base 1. Pressure sensors monitor the pressure changes at each support point in real time and feed the data back to the intelligent control system. The system dynamically adjusts the damping parameters according to the pressure distribution (such as by adjusting the spring preload to balance the load) to ensure stable operation of the vibrating screen. The support base 1, as the basic frame, evenly transmits the dispersed vibration energy to the ground, avoiding local overload. Then, during the disassembly and separation stage, when disassembly is required... When disassembling the vibrating screen, rotate the rotating block 7 in the opposite direction, causing the rotating threaded rod sleeve 17 to rotate in the opposite direction. This causes the rotating threaded rod 9 to retract and pull the slider 8 out of the second slider groove 12, releasing the limit on the fixed slider 5. The fixed slider 5 slides outward along the first fixed slider groove 11 under manual pushing, and its end is pulled out from the second fixed slider groove 14, releasing the lateral locking. At this time, the constraint between the positioning part 13 and the positioning slide groove 6 is released. Lifting the vibrating screen upward will allow the positioning part 13 to disengage from the positioning slide groove 6, completing the disassembly. If it is magnetically positioned, it can be separated simply by overcoming the magnetic force, greatly simplifying the disassembly process.

[0034] The locking of the fixed slider 5 and the positioning part 13 can be released by rotating the rotating block 7 in the reverse direction in the installation component, avoiding the problems of "rusted bolts are difficult to disassemble and violent operation damages the equipment" faced by bolt connections. This structure does not require destructive means such as hammering or cutting, and can complete the disassembly of the vibrating screen in a short time. If common faults such as ore blockage and screen damage occur, the maintenance downtime is reduced, the duration of mine production interruption is reduced, and the cascading impact is reduced.

[0035] Structural Description: Support Base 1: As the basic load-bearing component of the entire base, Support Base 1 is a rigid frame structure used to fix and support all shock absorption mechanisms 2. Four shock absorption mechanisms 2 are installed on the upper surface of its four corners by bolts. The middle area is reserved for the installation space of the vibrating screen to ensure that the overall force of the vibrating screen is evenly transmitted to the base.

[0036] Each damping mechanism 2 consists of a spring damper, a fixed plate, and a pressure sensor. The spring damper, as the core damping component, absorbs the high-frequency vibration generated during the operation of the vibrating screen through elastic deformation, reducing the transmission of vibration to the support base 1 and the ground. The fixed plate is used to connect and fix the damping mechanism 2 to the support base 1 and the mounting base 3, ensuring that the damper is stably subjected to force. The pressure sensor is integrated between the spring damper and the mounting base 3 to monitor the pressure transmitted from the vibrating screen to the support point in real time, providing data support for intelligent damping control.

[0037] Mounting base 3: Mounting base 3 is a transition component connecting the shock absorption mechanism 2 and the vibrating screen. Each mounting base 3 has a positioning slide groove 6 (for accommodating the positioning component 13) on its upper surface. The left and right outer walls are symmetrically provided with first fixed slider grooves 11 (for installing fixed sliders 5). The front and rear inner walls of the first fixed slider grooves 11 are provided with second slider grooves 12, which cooperate with the sliders 8 on the fixed sliders 5 to achieve the locking function.

[0038] Vibrating screen connecting seat 4: Fixed to the bottom of the vibrating screen, with its lower surface rigidly connected to the positioning part 13, used to transfer the load of the vibrating screen to the mounting seat 3.

[0039] Fixed slider 5: Symmetrically installed in the first fixed slider groove 11, it can slide laterally along the groove. The end near the positioning member 13 is embedded in the second fixed slider groove 14 of the positioning member 13 to achieve lateral fixation of the vibrating screen.

[0040] Slider 8: Located in the first slider groove 10 on the front and rear outer walls of the fixed slider 5, it can slide longitudinally along the groove, and its end extends into the second slider groove 12. It restricts the lateral displacement of the fixed slider 5 by clamping with the groove.

[0041] Rotating block 7 and rotating threaded rod sleeve 17: Rotating block 7 and rotating threaded rod sleeve 17 are rigidly connected. When rotating block 7 rotates, it drives rotating threaded rod sleeve 17 to rotate synchronously, providing power for the movement of slider 8.

[0042] Rotating threaded rod 9: One end is fixed to the slider 8, and the other end is threadedly connected to the rotating threaded rod sleeve 17. When the rotating threaded rod sleeve 17 rotates, it drives the rotating threaded rod 9 to extend and retract, thereby causing the slider 8 to slide along the first slider groove 10.

[0043] Positioning component 13: As a positioning structure between the vibrating screen connecting seat 4 and the mounting seat 3, its outer wall slides in fit with the positioning slide groove 6, and the front and rear sides are provided with protrusions that are adapted to the conical slide groove 15. When inserted into the positioning slide groove 6, the initial positioning is achieved by the conical surface guide. When the positioning component 13 is a magnetic positioning slide 16, its bottom magnetic block is attracted to the magnetic seat in the positioning slide groove 6, further enhancing the pre-positioning stability.

[0044] Positioning slide groove 6: It is formed on the upper surface of the mounting base 3 and matches the shape of the positioning part 13. It restricts the horizontal displacement of the vibrating screen through sliding fit.

[0045] Conical groove 15: Located on the front and rear inner walls of the positioning slide groove 6, it cooperates with the protrusion on the outer wall of the positioning element 13, and uses the conical guiding effect to ensure that the positioning element 13 is accurately inserted into the groove.

[0046] The second fixed slider groove 14 is formed on the left and right outer walls of the positioning member 13 and is adapted to the end of the fixed slider 5. The rigid connection between the vibrating screen and the mounting base 3 is achieved by embedding the fixed slider 5.

[0047] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
