Description
Technical Field
[0001] The utility model relates to the technical field of limestone reclaimers, in particular to a slewing bearing of a limestone reclaimer with a protective function. Background Art
[0002] Limestone is an important industrial raw material with a wide range of applications. The most common uses are in the production of lime (calcium oxide) and cement. In the metallurgical industry, limestone is also used as a raw material for ironmaking. In addition, limestone is also used in soil improvement, sewage treatment, glass manufacturing, steelmaking in steel production, building materials manufacturing and other fields. Reclaimers are needed in the processing of limestone. Limestone reclaimers are equipment used to extract limestone from ore or ore bodies. They are usually an important part of industrial production lines, used to collect raw limestone from mines or veins for subsequent processing and utilization, among which slewing bearings are important components of reclaimers.
[0003] The slewing bearing of a traditional limestone reclaimer bears the functions of supporting and slewing mechanism. In a limestone reclaimer, the slewing bearing is usually located at the bottom or chassis of the machine body to support the smooth operation of rotating parts (such as a slewing table). The slewing bearing is usually made of materials such as high-strength alloy steel or cast iron to ensure that it has sufficient strength and wear resistance. They are designed to withstand the overall weight of the machine and possible shocks and vibrations in the working environment. The slewing bearing usually includes internal mechanisms such as ball bearings or sliding bearings to ensure smooth and unobstructed slewing motion of the machine. During operation, these bearings are kept in good lubrication through a lubrication system.
[0004] However, the traditional slewing bearing does not have a dustproof function and has poor sealing. As a result, fine dust may fall onto the slewing bearing platform when the limestone reclaimer is running. Frequent cleaning is required to prevent dust from entering the bearing, which will affect the lubrication effect of the equipment and cause damage, affecting production efficiency. In addition, the lubrication frequency is high, and dust accumulation causes greater damage to the bearing. Utility Model Content
[0005] In order to make up for the above shortcomings, the utility model provides a limestone reclaimer slewing bearing with a protective function, aiming to improve the problem that the traditional slewing bearing does not have a dustproof function, which will affect the lubrication effect of the equipment and cause damage, affect production efficiency, require high lubrication frequency, and dust accumulation causes greater damage to the bearing.
[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a slewing bearing of a limestone material reclaimer with a protective function, comprising a lower car body, a bearing is rotatably connected to the top of the lower car body, a steel plate enclosure is fixedly connected to the top of the lower car body, a plurality of L-shaped baffles are fixedly connected to the outer wall of the bearing, a dustproof cloth is arranged on the top of the L-shaped baffle, a plurality of fixed plates are fixedly connected to the upper surface of the lower car body, a fixed platform is fixedly connected to the inside of the fixed plate, a connecting shaft is fixedly connected to the side wall of the fixed platform, a clamping plate is fixedly connected to one end of the connecting shaft, a spring is sleeved on the outer wall of the connecting shaft, a fixing bolt is threadedly connected to the inside of each of the fixed plates, and a connecting assembly is arranged on the outer wall of the steel plate enclosure.

[0011] Furthermore, one end of the second connecting rod is fixedly connected to the outer wall of the second rotating shaft, and the first rotating shaft is rotatably connected inside the first turntable.
[0012] Furthermore, a connecting rod 1 is fixedly connected to an outer wall of the rotating shaft 1.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] Reference Figure 1 and Figure 2The utility model provides an embodiment: a slewing bearing of a limestone reclaimer with a protective function, comprising a lower body 1, a bearing 2 is rotatably connected to the top of the lower body 1, a steel plate enclosure 3 is fixedly connected to the top of the lower body 1, a plurality of L-shaped baffles 4 are fixedly connected to the outer wall of the bearing 2, a dustproof cloth 5 is arranged on the top of the L-shaped baffle 4, a plurality of fixing plates 6 are fixedly connected to the upper surface of the lower body 1, a fixing platform 7 is fixedly connected inside the fixing plate 6, a connecting shaft 8 is fixedly connected to the side wall of the fixing platform 7, a clamping plate 9 is fixedly connected to one end of the connecting shaft 8, a spring 10 is sleeved on the outer wall of the connecting shaft 8, a fixing bolt 11 is threadedly connected inside each fixing plate 6, and a connecting assembly is arranged on the outer wall of the steel plate enclosure 3.
[0024] Specifically, first, the fixing plate 6 is firmly fixed to the surface of the lower body 1 by the fixing bolts 11. This step ensures that the fixing plate 6 will not loosen or shift during operation. Tension is applied to the card plate 9 on the surface of the connecting shaft 8 by the spring 10, and the card plate 9 is firmly fixed in position by the fixing platform 7, so that the card plate 9 can remain upright. The engagement of multiple card plates 9 forms an effective fixed structure, which firmly holds the steel plate enclosure 3 to prevent it from shifting during operation. The surrounding shielding of the steel plate enclosure 3 plays an important protective role against dust generated during the operation of the limestone reclaimer. The sealing measures of multiple L-shaped baffles 4 and dustproof cloth 5 on the outer wall of the bearing 2 effectively prevent dust from entering the interior of the bearing 2, thereby reducing the wear and damage to the bearing 2 and ensuring the smoothness and stability of its rotation. This structural design not only places the bearing 2 in a relatively closed environment, but also eliminates the need for frequent cleaning, greatly reducing the need for equipment maintenance, reducing maintenance costs and operating complexity. Therefore, this dustproof protection structure can not only effectively extend the service life of the bearing 2, reduce the maintenance frequency and lubrication costs of the equipment, but also improve the reliability and stability of the equipment.
[0025] Reference Figure 3 The connecting component includes a connecting frame 12, and multiple connecting frames 12 are fixedly connected to the side wall of the steel plate enclosure 3. The side wall of the connecting frame 12 is fixedly connected with a turntable 13, and the side wall of the connecting frame 12 is fixedly connected with a turntable 3 15. The turntable 3 15 is internally rotatably connected with a hydraulic rod 16, and the output end of the hydraulic rod 16 is fixedly connected with a connecting rod 2 20. The side wall of the connecting frame 12 is fixedly connected with a turntable 2 14, and the turntable 2 14 is internally rotatably connected with a rotating shaft 2 18, one end of the connecting rod 2 20 is fixedly connected to the outer wall of the rotating shaft 2 18, the turntable 13 is internally rotatably connected with a rotating shaft 17, and the outer wall of the rotating shaft 17 is fixedly connected with a connecting rod 19, and the side wall of the connecting frame 12 is provided with a pneumatic suction nozzle 21, one end of the connecting rod 19 is rotatably connected to the side wall of the pneumatic suction nozzle 21, and one end of the connecting rod 2 20 is rotatably connected to the side wall of the pneumatic suction nozzle 21.
[0026] Specifically, the hydraulic rod 16 applies force to the connecting rod 20 by outputting a push-pull force. This action drives the rotation of the rotating shaft 2 18 inside the turntable 2 14. At the same time, since the connecting rod 20 and the connecting rod 1 19 are simultaneously connected to the side wall of the pneumatic suction nozzle 21, the connecting rod 1 19 also begins to move accordingly, driving the rotation of the rotating shaft 17 inside the turntable 13. In this way, the movement process of the connecting rod 1 19 and the connecting rod 2 20 changing the inclination angle at the same time enables the pneumatic suction nozzle 21 to be lifted upward. Through this process, the pneumatic suction nozzle 21 can effectively remove the dust inside the steel plate enclosure 3. Such an operation can avoid excessive accumulation of dust inside the steel plate enclosure 3, thereby keeping the equipment clean and reducing the difficulty of dust cleaning. This regular cleaning operation not only ensures the normal operation of the limestone slewing bearing, but also helps to extend the service life of the equipment, improve production efficiency and equipment reliability.
[0027] Working principle: When the bearing 2 needs to be dustproofed, first fix the fixing plate 6 to the surface of the lower body 1 through the fixing bolts 11. At this time, the spring 10 exerts tension on the clamping plate 9 on the surface of the connecting shaft 8 and fixes the fixing platform 7 to keep the clamping plate 9 upright. The clamping of multiple clamping plates 9 can effectively fix the steel plate enclosure 3 so that it is not easy to shift. The surrounding shielding of the steel plate enclosure 3 can protect the limestone reclaimer from dust during operation. The arrangement of multiple L-shaped baffles 4 on the outer wall of the bearing 2 and the sealing of the dustproof cloth 5 on the top of the bearing 2 can effectively seal the bottom position of the bearing 2, preventing dust from entering the bearing 2 to damage it and affect its rotation smoothness. This structure protects the slewing bearing from dust, and there is no need for frequent cleaning to prevent dust from entering the bearing 2, reducing equipment The lubrication frequency is increased, and the lubrication cost is reduced while reducing the damage to the bearing 2. When it is necessary to clean the dust inside the steel plate enclosure 3, the hydraulic rod 16 is started, and the hydraulic rod 16 outputs a push-pull force to the connecting rod 20. At this time, the connecting rod 20 is subjected to the force and drives the rotating shaft 2 18 to rotate inside the turntable 14. Since the connecting rod 20 and the connecting rod 1 19 are connected to the side wall of the pneumatic suction nozzle 21 at the same time, the connecting rod 1 19 also drives the rotating shaft 17 to rotate inside the turntable 13. At this time, the connecting rod 1 19 and the connecting rod 20 change the inclination angle at the same time. In this process, the pneumatic suction nozzle 21 can be lifted up, so that the dust inside the steel plate enclosure 3 can be effectively sucked out during its operation to avoid excessive dust accumulation inside the steel plate enclosure 3. At the same time, the difficulty of dust transfer is reduced, and the normal operation of the limestone slewing bearing is guaranteed.
