Description

Technical Field

[0001] This utility model relates to the field of rotary kiln thrust roller technology, and in particular to a rotary kiln thrust roller device. Background Technology

[0002] The function of a rotary kiln thrust roller is to protect the rolling ring and the cylinder, preventing friction or movement between them, thereby ensuring the normal operation of the equipment. Typically, a rotary kiln thrust roller consists of several main parts, including a central shaft, bearing bush, rolling ring, thrust roller body, and support components. The main task of this equipment is to provide protection for the rolling ring and the cylinder to prevent potential hazards caused by friction or movement.

[0003] In actual operation, existing rotary kiln thrust roller devices generate friction between the roller ring and the bearing. This friction can cause high temperatures in the thrust roller body and supporting components. Due to the combined effects of high temperature and friction, the lubricating oil inside the rotary kiln thrust roller base will evaporate and carbonize. As the lubricating oil decreases, the internal wear of the thrust roller will become severe, thus affecting the normal operation of the rotary kiln thrust roller device. Therefore, this utility model provides a rotary kiln thrust roller device. Utility Model Content

[0015] (III) Beneficial Effects

[0016] This utility model provides a rotary kiln thrust roller device. It has the following beneficial effects:

[0017] 1. The fixed ring on the lower surface of the thrust roller rotates due to the rotation of the thrust roller disc. The fixed ring intermittently pushes the pressure rod downward through the inclined block. During the downward movement of the pressure rod, the return spring A is compressed and undergoes elastic deformation. At the same time, the pressure plate is pushed to compress the oil-absorbing sponge, and the lubricating oil in the oil-absorbing sponge is transported to the bottom cylinder of the thrust roller through the oil supply pipe, thereby achieving the effect of oil supply. Meanwhile, the oil storage tank on one side of the piston box can replenish the oil-absorbing sponge with oil. When the inclined block is no longer in contact with the top of the pressure rod, the return spring A restores its deformation, thereby driving the pressure rod back to its original position, achieving the effect of intermittently supplying oil to the bottom cylinder of the thrust roller.

[0018] 2. The sealing plug will push the slide bar to move, and at the same time squeeze the return spring B, causing the return spring B to undergo elastic deformation, so that the lubricating oil flows into the oil delivery pipe. When the pressure of the delivered lubricating oil decreases, the return spring B will restore its elastic deformation, thereby pushing the sealing plug back to its original position and sealing the oil inlet, thus preventing the lubricating oil in the oil delivery pipe from flowing back.

[0019] 3. The turntable is driven to rotate by rotating the throttle. The rotation of the turntable drives the bidirectional screw to rotate. The two sliding plates on the surface of the bidirectional screw move synchronously and in opposite directions on the slide rail surface by means of the thread, thereby driving the guide wheel disc on the bottom cylinder of the guide wheel to move, so as to adjust the distance between the two guide wheel discs and improve the applicability of the device.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] Example 1

[0030] Reference Figure 3 , Figure 4 and Figure 6 This is the first embodiment of the present utility model. This embodiment provides a rotary kiln thrust roller device, including a thrust roller bottom cylinder 2 and a bottom plate 1. A thrust roller disc 3 is installed inside the thrust roller bottom cylinder 2, and an oil conveying component 5 is provided on the surface of the thrust roller bottom cylinder 2.

[0031] The oil delivery assembly 5 includes a support frame 501, which is located on one side of the thrust roller bottom cylinder. A piston box 502 is fixedly connected to the top of the support frame 501. An oil-absorbing sponge 503 is provided on the inner wall of the piston box 502. A pressure plate 504 is provided on the upper surface of the oil-absorbing sponge 503. A lower pressure rod 505 is fixedly connected to the surface of the pressure plate 504. The upper end of the lower pressure rod 505 passes through the top of the piston box 502 and is slidably connected to an inclined block 507. A fixing ring 508 is fixedly connected to the upper end of the inclined block 507. An oil delivery pipe 509 is fixedly connected to one side of the piston box 502. The oil delivery pipe 509 is connected to the top of the thrust roller bottom cylinder 2, and an anti-backflow assembly 6 is provided on the surface of the oil delivery pipe 509.

[0032] Specifically, an oil storage tank 510 is fixedly connected to the side of the piston box 502 away from the oil supply pipe 509. A liquid level window 511 is opened on the surface of the oil storage tank 510. A return spring A506 is sleeved on the surface of the pressure rod 505. The lower end of the return spring A506 is fixedly connected to the top of the piston box 502.

[0033] Furthermore, when the kiln body drives the thrust roller 3 to rotate, the thrust roller 3 drives the fixed ring 508 on the lower surface to rotate. The fixed ring 508 intermittently pushes the lower pressure rod 505 downward through the inclined block 507. During the downward movement of the lower pressure rod 505, the return spring A506 is squeezed and undergoes elastic deformation. At the same time, the pressure plate 504 is pushed to squeeze the oil-absorbing sponge 503, and the lubricating oil in the oil-absorbing sponge 503 is transported to the inside of the thrust roller bottom cylinder 2 through the oil delivery pipe 509, thereby achieving the effect of oil delivery. At the same time, the oil storage tank 510 on one side of the piston box 502 can replenish the oil-absorbing sponge 503 with oil. When the inclined block 507 is no longer in contact with the top of the lower pressure rod 505, the return spring A506 restores the deformation, thereby driving the lower pressure rod 505 back to its original position, achieving the effect of intermittently delivering oil to the thrust roller bottom cylinder 2.

[0034] Example 2

[0035] Reference Figure 4 and Figure 5 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The anti-backflow component 6 includes a backflow pipe 601, which is fixedly connected to the oil supply pipe 509. An oil inlet 602 is provided on the side of the backflow pipe 601 near the piston box 502. A sealing plug 603 is slidably connected to the inner wall of the oil inlet 602. A sliding rod 604 is fixedly connected to one side of the sealing plug 603. A fixing bracket 605 is slidably connected to the surface of the sliding rod 604. The fixing bracket 605 is fixedly connected to the inner wall of the backflow pipe 601.

[0036] Specifically, a return spring B606 is sleeved on the surface of the slide bar 604, and the return spring B606 is located between the seal 603 plug and the fixing bracket 605.

[0037] Furthermore, when the lubricating oil pushes the sealing plug 603 into the oil inlet 602, the sealing plug 603 will push the slide bar 604 to move, and at the same time squeeze the return spring B606, causing the return spring B606 to undergo elastic deformation, so that the lubricating oil flows into the oil supply pipe 509. When the pressure of the delivered lubricating oil decreases, the return spring B606 restores its elastic deformation, thereby pushing the sealing plug 603 back to its original position and sealing the oil inlet 602, thus preventing the lubricating oil in the oil supply pipe 509 from flowing back.

[0038] Example 3

[0039] Reference Figure 1 and Figure 2This is the third embodiment of the present invention. This embodiment is based on the previous embodiment. The surface of the base plate 1 is provided with an adjustment component 4. The adjustment component includes a slide rail 401. The lower end of the slide rail 401 is fixedly connected to the surface of the base plate 1, and the upper end of the slide rail 401 is slidably connected to a sliding plate 402. The upper surface of the sliding plate 402 is fixedly connected to the lower end of the wheel base, and the lower surface of the sliding plate 402 is threadedly connected to a bidirectional screw 403. The two ends of the bidirectional screw 403 are rotatably connected to a fixing plate 404, and the lower end of the fixing plate 404 is fixedly connected to the surface of the base plate 1.

[0040] Specifically, one end of the bidirectional screw 403 passes through the side wall of the fixing plate 404 and is fixedly connected to the turntable 405, and the surface of the turntable 405 is fixedly connected to the handle 406.

[0041] Furthermore, when it is necessary to adjust the distance between the two guide wheel discs 3, the throttle 406 can be rotated to drive the turntable 405 to rotate. As the turntable 405 rotates, it drives the bidirectional screw 403 to rotate. The two sliding plates 402 on the surface of the bidirectional screw 403 move synchronously in opposite directions on the surface of the slide rail 401 by means of the thread, thereby driving the guide wheel discs 3 on the guide wheel base cylinder 2 to move, so as to achieve the effect of adjusting the distance between the two guide wheel discs 3 and improve the applicability of the device.

[0042] Working Principle: During use, when adjusting the distance between the two retaining roller discs 3, the handle 406 can be rotated to drive the turntable 405 to rotate. Simultaneously, the turntable 405 rotates, driving the bidirectional screw 403 to rotate. Two sliding plates 402 on the surface of the bidirectional screw 403 move synchronously in opposite directions on the slide rail 401 via the threaded connection, thereby moving the retaining roller discs 3 on the retaining roller base cylinder 2. This achieves the effect of adjusting the distance between the two retaining roller discs 3, improving the applicability of the device. When the kiln body drives the retaining roller discs 3 to rotate, the retaining roller discs 3 drive the fixing ring 508 on the lower surface to rotate. The fixing ring 508 intermittently pushes the lower pressure rod 505 downwards via the inclined block 507. During the downward movement of the lower pressure rod 505, it compresses the return spring A506, causing elastic deformation. Simultaneously, it pushes the pressure plate 504 to compress the oil-absorbing sponge 503, allowing the lubricating oil in the oil-absorbing sponge 503 to pass through the oil delivery pipe. Oil 509 is delivered to the bottom cylinder 2 of the thrust roller, thereby achieving the effect of oil delivery. At the same time, the oil storage tank 510 on one side of the piston box 502 can replenish the oil-absorbing sponge 503. When the inclined block 507 is no longer in contact with the top of the lowering rod 505, the return spring A506 restores its deformation, thereby driving the lowering rod 505 back to its original position, achieving the effect of intermittently delivering oil to the bottom cylinder 2 of the thrust roller. When the lubricating oil pushes the sealing plug 603 into the oil inlet 602, the sealing plug 603 will push the slide rod 604 to move, and at the same time squeeze the return spring B606, causing the return spring B606 to undergo elastic deformation, so that the lubricating oil flows into the oil delivery pipe 509. When the pressure of the delivered lubricating oil decreases, the return spring B606 restores its elastic deformation, thereby pushing the sealing plug 603 back to its original position, sealing the oil inlet 602, thereby preventing the lubricating oil in the oil delivery pipe 509 from flowing back.
