[0002] A coal mill is a machine that crushes coal blocks and grinds them into pulverized coal. It is an important auxiliary equipment for a pulverized coal boiler. There are models such as vertical pulverizers, high-pressure suspension rollers, medium-speed micro-pulverizers, super-pressure trapezoidal mills, Raymond mills, etc. Generally, the coal mill is fixedly installed on an installation base through bolts. Since the crushing of coal blocks is a relatively violent process, the fixing bolts may become loose under the action of vibration, resulting in the instability of the coal mill body. In addition, the support legs of the existing installation base may be deformed after long-term use, and this deformation is difficult to observe with the naked eye. In the long run, it may cause damage to the installation base. For this reason, we propose a reinforcement structure of a coal mill base to solve the above problems. Content of the Utility Model

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4 , an embodiment provided by the present utility model: a coal mill base reinforcement structure, including a mounting base 1, on which a coal mill fixing component 2 is installed,

[0022] A mounting frame 3 is fixedly installed on the mounting base 1. Mounting blocks 4 are fixedly installed on the left and right sides of the coal mill fixing component 2. The mounting blocks 4 are fixedly installed on the mounting frame 3 through bolts. An anti-loosening block 5 is arranged on the mounting blocks 4, and a support cylinder 6 is arranged in the mounting base 1;

[0023] An anti-disengagement mechanism is arranged in the anti-loosening block 5, and the anti-disengagement mechanism is used to prevent the bolts from falling off;

[0024] A support mechanism is arranged in the mounting base 1, and the support mechanism is used to increase the support of the mounting base 1. Through the anti-disengagement mechanism of this device, it is difficult for the bolts to become loose when the device vibrates, increasing the stability during the use of the device. A support mechanism is also provided to additionally increase the support force of the mounting base 1;

[0025] Furthermore, the anti-loosening mechanism includes a first limiting groove 7. The lower side of the anti-loosening block 5 is provided with a first limiting groove 7, and the size of the first limiting groove 7 is adapted to the size of the bolt provided on the mounting block 4. A first movable groove 8 is provided at the central position of the mounting block 4, and a limiting rod 9 is movably inserted into the first movable groove 8. A spring 10 is sleeved on the limiting rod 9, and the spring 10 abuts against the upper side of the first movable groove 8. A limiting piece 11 is fixedly installed on the limiting rod 9. A slot 12 is provided at the central position of the anti-loosening block 5, and two groups of second limiting grooves 13 are provided on the slot 12. The two groups of second limiting grooves 13 are perpendicular to each other and the depth of one group of second limiting grooves 13 is less than the depth of the other group of second limiting grooves 13. This structure makes it difficult for the bolt to vibrate and loosen, increases the stability of the equipment during use, and moreover, the anti-loosening block 5 can be disassembled, increasing the adaptability of the equipment during use.

[0026] Furthermore, second movable grooves 14 are provided on the front and rear sides of the anti-loosening block 5, and pressing blocks 15 are movably inserted into the second movable grooves 14. The lower ends of the pressing blocks 15 abut against the bolts provided on the mounting block 4. Springs 10 are provided in the second movable grooves 14, and the springs 10 abut against the pressing blocks 15. This structure enables the anti-loosening block 5 to also have the ability to press the bolts when vibrating, increasing the stability of the equipment during use.

[0027] Furthermore, the support mechanism includes a plug rod 16. The plug rod 16 is movably inserted into the support cylinder 6. Mounting pieces 17 are fixedly installed at both ends of the support cylinder 6 and the plug rod 16. Screw assemblies 18 are provided at the four corners of the mounting pieces 17, and the mounting pieces 17 are installed in the mounting base 1 through the screw assemblies 18. This structure enables the mounting base 1 to have additional support and the support cylinder 6 and the plug rod 16 can move to a certain extent, making the installation of the support cylinder 6 and the plug rod 16 more convenient.

[0028] Furthermore, a rubber sleeve 19 is fixedly installed in the support cylinder 6, and the plug rod 16 is inserted into the rubber sleeve 19 and fits tightly with the rubber sleeve 19. This structure enables the support cylinder 6 and the plug rod 16 to be closer when installed by compressing the rubber sleeve 19, and reduces the mutual collision between the support cylinder 6 and the plug rod 16 during vibration.

[0029] Furthermore, identification blocks 20 are uniformly arranged in an array on the four support legs of the mounting base 1, and the distances between the identification blocks 20 are equal. This structure enables the deformation of the support legs of the mounting base 1 to be observed more clearly, enabling the user to selectively assemble the support cylinder 6 and increasing the functionality of the equipment during use.

[0030] Working principle: When in use, place the coal mill fixing component 2 on the mounting base 1, then fix the mounting block 4 on the coal mill fixing component 2 to the mounting frame 3 through bolts, and then place the anti-loosening block 5 on the mounting block 4 so that the first limiting groove 7 covers the bolt. At this time, the pressing block 15 abuts against the bolt, and the limiting rod 9 is inserted into the slot 12. Then pinch the limiting piece 11 and pull it upward. At this time, the spring 10 is compressed, and then rotate the limiting piece 11 so that the limiting piece 11 is engaged into another group of second limiting grooves 13 to complete the fixation. The user can judge whether the support legs of the mounting base 1 are deformed according to whether the spacing between the identification blocks 20 is neat. The support cylinder 6 can be selectively assembled, placed at a suitable position in the mounting base 1, and fixed through the screw component 18. When fixing, the insertion rod 16 and the support cylinder 6 will displace relative to each other and compress the rubber sleeve 19 for fixation. The above is the entire working principle of the present utility model.

[0031] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, it is intended to include all changes falling within the meaning and scope of the equivalent elements of the claims in the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.
