[0022] In order to clearly and completely describe the purpose and technical solution of the present invention and make its advantages more clearly understood, the following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention and are not intended to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] For the purpose of simplicity and illustration, the principles of the embodiments are described primarily with reference to examples. In the following description, many specific details are provided to provide a thorough understanding of the embodiments. However, it will be apparent to those skilled in the art that these embodiments may not be limited to these specific details in practice. In some instances, well-known methods and structures are not described in detail to avoid unnecessarily obscuring the understanding of these embodiments. In addition, all embodiments may be used in combination with each other.

[0024] See also Figures 1 to 5 The utility model provides a technical solution: a roller structure for replacing a coal conveyor belt.

[0025] In the first embodiment, an output rod 4 is provided inside the electric push rod 2, and a push plate 3 is fixed to the end of the output rod 4. When the electric push rod 2 is started, the output rod 4 is driven to move toward the belt, so that the push plate 3 supports the belt and the belt is separated from the roller. At this time, the roller can be replaced, realizing the convenience of replacing the roller of the belt conveyor body 1. A fixing block 6 is fixed to the outer surface of the end of the electric push rod 2.

[0026] A spring 10 is sleeved on the outer surface of the telescopic block 7, and a gear 12 is provided at one end of the telescopic block 7. The outer surface of the gear 12 is provided with a first tooth groove 13 and a second tooth groove 14. Since an arc surface is provided on one side of the end of the telescopic block 7, the output rod 4 will be restricted by the telescopic block 7 when it descends, so that the gear 12 cannot rotate. The inability of the gear 12 to rotate will cause the output rod 4 to be unable to move, thereby preventing the output rod 4 from descending due to excessive weight of the coal on the belt, thereby preventing safety hazards.

[0027] On the basis of Example 1, in order to facilitate the replacement of the rollers of the belt conveyor body 1, the electric push rod 2 is located below the belt conveyor body 1, and a tooth block 5 is fixed to the outer surface of the output rod 4. The tooth block 5 corresponds to the second tooth groove 14, and the tooth block 5 is clamped in the second tooth groove 14. The fixed block 6 is 'U'-shaped, and the opening of the fixed block 6 corresponds to the tooth block 5.

[0028] A notch 8 is provided at the end of the fixed block 6 , a receiving groove 9 is provided near the end of the notch 8 , the telescopic block 7 is provided on the inner wall of the notch 8 , the spring 10 is located on the inner wall of the notch 8 , and a baffle 11 is fixed on the outer surface of the telescopic block 7 .

[0029] The baffle 11 is located on the inner wall of the slot 8 , and the baffle 11 is located on the outer surface of the telescopic block 7 near the output rod 4 . The end size of the telescopic block 7 is the same as the size of the receiving slot 9 , and the diameter of the baffle 11 is the same as the inner wall diameter of the slot 8 .

[0030] The end size of the baffle 11 is larger than the end size of the telescopic block 7, and the baffle 11 corresponds to the notch 8. The baffle 11 is clamped in the notch 8, and the two are movably connected.

[0031] The end surface of the telescopic block 7 close to the gear 12 is curved, and two groups of second tooth grooves 14 are provided. The two groups of second tooth grooves 14 are symmetrically distributed on the outer surface of the gear 12, and the first tooth groove 13 is located between the two groups of second tooth grooves 14.

[0032] In actual use, when it is necessary to replace the roller of the belt conveyor body 1, first place the electric push rod 2 at the roller that needs to be replaced, then start the electric push rod 2 to drive the output rod 4 to move toward the belt, so that the push plate 3 supports the belt and the belt is separated from the roller. At this time, the roller can be replaced, which realizes the convenience of replacing the roller of the belt conveyor body 1; since the tooth block 5 is fixed on the outer surface of the output rod 4, the movement of the output rod 4 will drive the gear 12 to rotate through the first tooth groove 13, and since the surface of one side of the end of the telescopic block 7 is provided with an arc surface, the output rod 4 will not be restricted by the telescopic block 7 when it rises, but will be restricted by the telescopic block 7 when the output rod 4 falls, so that the gear 12 cannot rotate. The failure of the gear 12 to rotate will cause the output rod 4 to be unable to move, thereby preventing the output rod 4 from falling due to the excessive weight of the coal on the belt, thereby preventing safety hazards, and achieving safety when replacing the roller of the belt conveyor body.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
