The existing anti-reversal devices are mostly coordinated with ratchets and pawls. Relying solely on this to prevent reversal has a small force and a large load, resulting in a shortened service life. Therefore, an anti-reversal device for a belt conveyor is proposed. Utility Model Content

[0010] Beneficial effects

[0011] The utility model provides an anti-reversal device for a belt conveyor. Compared with the prior art, it has the following beneficial effects:

[0012] (1) The anti-reversal device of the belt conveyor is provided with a belt conveyor, a motor, a rotating rod, a support block, a sliding rod 1, a sliding rod 2, a movable rod, a support plate 1, a slot, and a magnetic block. By turning on the motor to drive the rotating rod to rotate, the belt conveyor can operate normally to transport the goods.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on 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.

[0020] See also Figure 1-3 The utility model provides a technical solution: an anti-reversal device of a belt conveyor, comprising a belt conveyor 1, an outer wall of one side of the rotating rod 3 is fixedly connected to the inner wall of one side of the support block 4, and the outer wall of one side of the support block 4 is fixedly connected to the outer wall of one side of the sliding rod 1 5, and the outer wall of one side of the sliding rod 1 5 is inclined. A slot 9 is opened on the outer wall of one side of the sliding rod 2 6, and the inner wall of the slot 9 is fixedly connected to the outer wall of one side of the magnetic block 10. The sliding rod 1 5 is made of iron material, and the inner wall of the sliding rod 2 6 is fixedly connected to the outer wall of the movable rod 7, and one end of the movable rod 7 passes through the outer wall of the sliding rod 2 6 and extends to the outside of the sliding rod 2 6. One end of the movable rod 7 is hingedly mounted on the inner wall of one side of the support plate 1 8 by a torsion spring. The outer wall of one side of the support plate 1 8 is fixedly mounted on the ground, and the outer wall of one side of the movable rod 2 6 is adapted to the inner wall of the support plate 1 8.

[0021] When in use, the motor 2 is turned on to drive the rotating rod 3 to rotate, so that the belt conveyor 1 can operate normally to transport goods. By installing the support block 4 on the rotating rod 3 and the sliding rod 5 on the outer wall of the support block 4, the sliding rod 5 is rotated from the rotating rod 3 to the conveyor 1 during normal operation. Figure 3 The position shown rotates counterclockwise to transport the items to the top. At this time, when the sliding rod 1 5 moves to the sliding rod 2 6, it can squeeze the sliding rod 2 6 to deflect with the movable rod 7 as the axis. When an unexpected situation such as a sudden power outage occurs, the sliding rod 1 5 will move from the rotating rod 3 as the axis. Figure 3The position shown is rotated clockwise. At this time, the sliding rod 2 6 pops out to the side close to the sliding rod 1 5 under the action of the torsion spring. At the same time, the sliding rod 1 5 will slide into the slot 9 along the surface of the sliding rod 2 6. At the same time, the sliding rod 1 5 is adsorbed by the magnetic block 10, which ensures that the sliding rod 1 5 can slide into the slot 9 to a certain extent. The outer wall of the other side of the sliding rod 2 6 will rest on the inner wall of one side of the support plate 1 8, thereby limiting the rotating rod 3 and preventing the rotating rod 3 from continuing to rotate clockwise.

[0022] like Figure 1-4 As shown, the technical solution of this embodiment is different from that of the first embodiment and includes: a motor 2 is provided on the outside of the belt conveyor 1, the output end of the motor 2 is fixedly connected to one end of the rotating rod 3 through a coupling, and the motor 2 drives the belt conveyor 1 to run through the rotating rod 3, and a fixing groove is provided on one side outer wall of the rotating rod 3, and a fixing block 15 is provided on the outside of the fixing groove, and the fixing block 15 is adapted to the fixing groove, and the fixing block 15 and the fixing groove are both triangular in shape, and one side outer wall of the fixing block 15 is fixedly connected to one side outer wall of the sliding rod 3 14, and one side outer wall of the sliding rod 3 14 is slidably connected to the inner wall of the support plate 3 12, and one end of the sliding rod 3 14 passes through the outer wall of the support plate 3 12 and extends to the inside of the support plate 3 12 One side outer wall of the sliding rod three 14 is fixedly connected to one end of the spring 13, one side outer wall of the sliding rod three 14 is fixedly connected to one side outer wall of the magnet 16, one side outer wall of the support plate three 12 is fixedly connected to one side outer wall of the electromagnet 17, and the other end of the spring 13 is fixedly mounted on the inner wall of the support plate three 12. After the electromagnet 17 is energized, it is magnetically attracted to the magnet 16. One side outer wall of the support plate three 12 is fixedly connected to one side outer wall of the support plate two 11. One side outer wall of the rotating rod 3 is movably mounted on the inner wall of the support plate two 11 through a bearing. One end of the rotating rod 3 passes through the outer wall of the support plate two 11 and extends to the outside of the support plate two 11. One side outer wall of the support plate two 11 is fixedly mounted on the ground.

[0023] When in use, the supporting force is provided to the rotating rod 3 by the supporting plate 2 11, and the supporting plate 2 11 provides supporting force to the supporting plate 3 12. When the belt conveyor 1 encounters a sudden power outage during operation, the electromagnet 17 is powered off, causing the magnet 16 to lose its suction force, and under the action of the spring 13, the sliding rod 3 14 is driven to move toward the side close to the rotating rod 3. The supporting plate 3 12 limits the sliding rod 3 14, so that the sliding rod 3 14 can move linearly along the supporting plate 3 12, and the sliding rod 3 14 drives the fixed block 15 to be clamped into the rotating rod 3, further ensuring that the rotating rod 3 will not rotate clockwise.
