The scraper conveyor is responsible for conveying and cleaning the material in the cooler. If the turntable experiences problems such as scraper misalignment, it will cause friction and jamming between the scraper and the cooler shell. This friction and jamming will not only affect the normal conveying of materials and reduce production efficiency, but also aggravate equipment wear, shorten the service life of the equipment, and increase equipment maintenance costs and downtime.
[0003] However, due to wear and aging of various components, existing scraper conveyors for coolers suffer from severe displacement between the turntable track, support shaft, and housing. During operation, the scraper is prone to radial displacement, which causes friction and jamming between the turntable and the cooler housing, preventing the scraper conveyor from operating normally.

[0029] 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.
[0030] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a device for preventing the rotation of a rotary kiln cooler scraper conveyor turntable. It includes a retaining wheel cover 1. A groove is cut into the outer shell of the rotary kiln cooler scraper conveyor, allowing the entire device to be fixed to the west and south sides of the conveyor. An outer mounting plate 2 is detachably mounted on the surface of the retaining wheel cover 1 using bolts. A retaining wheel bracket 3 is fixedly connected to the rear end of the inner wall of the retaining wheel cover 1. Two sets of reinforcing ribs 4 are fixedly connected to the outer walls of the upper and lower sides of the retaining wheel bracket 3. These two sets of reinforcing ribs 4 are fixedly connected to the retaining wheel bracket 3, and the entire device is fixed to the inner end of the retaining wheel cover 1 by welding. This fixes the rotational position of the retaining wheel 6 and allows the retaining wheel 6 to pass through the groove in the retaining wheel cover 1, thus allowing it to contact the cooler scraper. This prevents the scraper from radially shifting during the operation of the scraper conveyor, and prevents the rotary kiln cooler turntable from shifting and causing friction and jamming with the cooler shell.
[0031] Reference Figure 2and Figure 3 The inner side wall of the wheel retainer bracket 3 has two sets of positioning grooves. The inner wall of each positioning groove contacts two sets of positioning blocks 5. These blocks are connected to the surface of the wheel retainer bracket 3 via positioning frames 7, and are threadedly connected to the wheel retainer bracket 3 via positioning screws 8 that pass through the positioning frames 7. This fixes the installation position of the two sets of positioning blocks 5 and the wheel retainer 6. The wheel retainer 6 is rotatably connected between the two sets of positioning blocks 5. The two sets of wheel retainers 6 on the west and south sides contact the scraper, preventing the scraper from shifting. The outer wall of the positioning frame 7 is in contact with the surface of the wheel stop bracket 3. The rear end of the wheel stop cover 1 is provided with a slot. The inner wall of the positioning frame 7 is slidably connected with a positioning screw 8. The surface of the wheel stop bracket 3 is provided with bolt holes. The positioning screw 8 is threadedly connected to the inner wall of the bolt holes of the wheel stop bracket 3. A special tool can be used to penetrate the positioning frame 7 to lock it with the wheel stop bracket 3, thereby fixing the installation position of the wheel stop 6 and the positioning block 5. The inner walls of the two sets of positioning blocks 5 are provided with lubrication components 9.
[0032] Reference Figure 3 and Figure 4 The lubrication assembly 9 includes an oil reservoir 91, which is slidably connected to the inner wall of the positioning block 5. The oil reservoir 91 is elastically connected to the inner wall of the positioning block 5 via a return spring 92. One end of the return spring 92 is fixedly connected to the inner wall of the positioning block 5, and the other end is fixedly connected to the outer wall of the oil reservoir 91. The function of the return spring 92 is to push the oil reservoir 91 so that the position of the steel ball 96 after it is in contact with the rotating shaft of the retaining wheel 6 is automatically reset. The rear end of the oil reservoir 91 has an internal thread, and the rear end of the oil reservoir 91 is threadedly connected to an oil filling bolt 93. The oil filling bolt 93 can be opened with a special tool to replenish the grease inside the oil reservoir 91. A bracket 94 is fixedly connected to the inner wall of the oil reservoir 91. The bracket 94 is elastically connected to the steel ball 96 via a limit spring 95. One end of the limit spring 95 is fixedly connected to the outer wall of the steel ball 96, and the other end is fixedly connected to the surface of the bracket 94.
[0033] Reference Figure 4The outer wall of the steel ball 96 contacts the side wall at the end of the oil reservoir 91. This contact allows the steel ball 96 to block and close the oil outlet of the oil reservoir 91. The limiting spring 95 automatically resets the steel ball 96 after it moves to contact the baffle wheel 6 and opens the oil outlet, thus blocking and closing the outlet. The outer wall of the steel ball 96 contacts the shaft of the baffle wheel 6. This contact allows the baffle wheel 6 to press the steel ball 96 against the inner wall of the oil reservoir 91 as the oil reservoir 91 moves synchronously. This allows the grease inside the oil reservoir 91 to overflow from the gap between the steel ball 96 and the oil reservoir 91, thus applying grease to the shaft of the baffle wheel 6 and preventing jamming during rotation.
[0034] Working principle: When installing the thrust roller 6, first place the two sets of positioning blocks 5 in the positioning grooves on the inner side wall of the thrust roller bracket 3, so that the thrust roller 6 is in a suitable rotational installation position. Then, the positioning frame 7 contacts the surface of the thrust roller bracket 3, so that the positioning frame 7 covers the outer wall of the positioning block 5. Next, use a special tool to pass the positioning screw 8 through the positioning frame 7 and thread it into the bolt hole of the thrust roller bracket 3. As the positioning screw 8 is screwed in, the positioning frame 7 is gradually pressed against the surface of the thrust roller bracket 3, thereby fixing the installation position of the two sets of positioning blocks 5 and the thrust roller 6. By setting such thrust rollers 6 on the west and south sides of the scraper conveyor turntable to contact the scraper, the radial displacement of the scraper is effectively limited, avoiding its deviation during operation and preventing friction and jamming with the cooler shell, thus ensuring the normal and stable operation of the scraper conveyor.
[0035] When the retaining wheel 6 rotates, and it is necessary to replenish grease at the location block 5, the oil reservoir 91 can be moved by pressing the inner wall of the positioning block 5, compressing the return spring 92. Simultaneously, during the movement of the oil reservoir 91, the steel ball 96 on its inner wall will contact the rotating shaft of the retaining wheel 6, and the steel ball 96 will be squeezed and moved along the inner wall of the oil reservoir 91. Under the squeezing force, the steel ball 96 overcomes the elastic force of the limiting spring 95 and moves along the inner wall of the oil reservoir 91, creating a gap between the steel ball 96 and the end side wall of the oil reservoir 91. The grease inside the oil reservoir 91 overflows from the gap and coats the shaft of the retainer wheel 6, lubricating the shaft, reducing frictional resistance during rotation, and preventing jamming. When the oil reservoir 91 is released, it automatically resets under the elastic action of the return spring 92. Simultaneously, when the pressure of the retainer wheel 6 shaft on the steel ball 96 disappears, the steel ball 96 resets under the elastic restoring force of the limit spring 95, re-contacting the end wall of the oil reservoir 91, blocking and closing the oil outlet to prevent grease leakage. When grease needs to be replenished, use a special tool to open the grease filler bolt 93, inject grease into the oil reservoir 91, and then close the grease filler bolt 93.
[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
