However, during braking, the brake pads are constantly in contact with the brake disc, and prolonged contact can cause the brake pads to overheat, accelerating wear on both. This utility model discloses a simple belt conveyor head braking device for an electric roller to solve the above problems. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0020] Example: Reference Figure 1-4 The illustrated simple electric roller belt conveyor head braking device includes two fixed plates 22, with an electric roller 1 installed between the two fixed plates 22. A brake disc 2 is installed on the mounting shaft of the electric roller 1. A U-shaped plate 3 is fixedly installed on the side of the fixed plate 22 on one side of the brake disc 2. Arc-shaped brake pads 4 are installed on the U-shaped plate 3 through two elastic mechanisms. The two arc-shaped brake pads 4 correspond to the positions of the brake disc 2. A mounting plate 8 is fixedly installed on the side of the U-shaped plate 3. A movable hydraulic cylinder 7 is fixedly installed on one side of the mounting plate 8. The movable hydraulic cylinder 7 passes through the mounting plate 8 and a telescopic hydraulic cylinder 6 is fixedly installed thereon. The movable hydraulic cylinder 7 and the telescopic hydraulic cylinder 6 are externally connected to an oil supply mechanism. A pressing mechanism is installed on the movable end of the telescopic hydraulic cylinder 6. The pressing mechanism is installed in cooperation with the two elastic mechanisms.

[0021] With the above structure: during braking, the telescopic hydraulic cylinder 6 and the pressing mechanism can be moved by activating the moving hydraulic cylinder 7. The pressing mechanism causes one of the elastic mechanisms to move, thereby causing one of the arc-shaped brake pads 4 to move for braking. After braking is completed, the moving hydraulic cylinder 7 is closed and the telescopic hydraulic cylinder 6 is activated. The output shaft of the telescopic hydraulic cylinder 6 extends and retracts, causing the pressing mechanism to press the two elastic mechanisms back and forth, thereby causing the two arc-shaped brake pads 4 to alternately brake the brake disc 2, effectively protecting the arc-shaped brake pads 4.

[0022] like Figure 2 , Figure 3 and Figure 4 As shown, the extrusion mechanism includes an L-shaped plate 5 fixedly installed at the movable end of the telescopic hydraulic cylinder 6. A movable plate 9 is fixedly installed at the bottom of the L-shaped plate 5, and a first extrusion assembly and a second extrusion assembly are fixedly installed at the bottom of the movable plate 9. The first extrusion assembly includes a first inclined block 17, a first straight block 18, and a second inclined block 19 connected in sequence. The first inclined block 17 and the second inclined block 19 are symmetrically arranged based on the first straight block 18, and the included angle between the sides of the first straight block 18 and the first inclined block 17 that are close to each other is an obtuse angle. By activating the movable hydraulic cylinder 7, the telescopic hydraulic cylinder 6 can be moved. The movement of the telescopic hydraulic cylinder 6 drives the L-shaped plate 5 and the movable plate 9 to move. The movement of the movable plate 9 drives the first inclined block 17 to move. The first inclined block 17 extrudes the left pressure roller 16, and the movement of the left pressure roller 16 drives the left rotating rod 15 and the left movable block 14 to move. This causes the two reset rods 11 to move, which in turn causes the left arc-shaped brake pad 4 to move. When the second pressure wheel 16 contacts the third inclined block 20, the left pressure wheel 16 separates from the first inclined block 17 and contacts the side of the first straight block 18. At this time, the left arc-shaped brake pad 4 contacts the brake disc 2 to brake. The second compression assembly includes the third inclined block 20 and the second straight block 21 connected to each other. The included angle between the sides of the third inclined block 20 and the second straight block 21 that are close to each other, the included angle between the sides of the first straight block 18 and the first inclined block 17 that are close to each other, and the included angle between the sides of the first straight block 18 and the second inclined block 19 that are close to each other are the same. The positions of the third inclined block 20 and the first straight block 18 are corresponding, the positions of the second straight block 21 and the second inclined block 19 are corresponding, and the third inclined block 20 and the first inclined block 17 are staggered. Close the moving hydraulic cylinder 7 and then start the telescopic hydraulic cylinder 6. The output shaft of the telescopic hydraulic cylinder 6 extends and retracts, causing the moving plate 9 to continue moving. The pressure roller 16 on the left moves on the first straight block 18. The sides of the first straight block 18 and the second straight block 21 are parallel to the inner walls of both sides of the U-shaped plate 3, so that the left arc-shaped brake pad 4 does not move. The pressure roller 16 on the right is squeezed by the third inclined block 20, causing the right pressure roller 16, the rotating rod 15, the movable block 14 and the two reset rods 11 to move, thereby causing the right arc-shaped brake pad 4 to approach the brake disc 2. When the left pressure roller 16 separates from the first straight block 18, the right pressure roller 16 contacts the second straight block 21. At the same time, the right arc-shaped brake pad 4 contacts the brake disc 2 for braking. When the arc-shaped brake pad 4 moves, the spring 13 will deform. When the left pressure roller 16 corresponds to the second inclined block 19, the arc-shaped brake pad 4 moves in the opposite direction under the left and right pressure of the spring 13.

[0023] like Figure 2 and Figure 3As shown, the elastic mechanism includes two reset holes 10 on the side of the U-shaped plate 3. Reset rods 11 are slidably installed in each of the two reset holes 10. One end of each reset rod 11 is fixedly installed on the side of the arc-shaped brake pad 4, and the other end is fixedly installed with a baffle 12. Springs 13 are sleeved on each reset rod 11, with both ends of the springs 13 fixedly installed on the baffle 12 and the adjacent sides of the U-shaped plate 3, respectively. When the arc-shaped brake pad 4 moves closer to the brake disc 2, the springs 13 deform. When the right pressure wheel 16 enters the third inclined block 20, the springs 13 cause the pressure wheel 16 to move in the opposite direction. When the left pressure wheel 16 enters the second inclined block 19, the springs 13 cause the pressure wheel 16 to move in the opposite direction.

[0024] like Figure 2 and Figure 3 As shown, the elastic mechanism also includes a movable block 14 fixedly mounted on the top of the two reset rods 11. A rotating rod 15 is fixedly mounted on the top of the movable block 14, and a pressure wheel 16 is rotatably sleeved on the rotating rod 15. The pressure wheel 16 corresponds to the position of the third inclined block 20 or the first inclined block 17. Due to the setting of the pressure wheel 16, the third inclined block 20 and the first inclined block 17 will squeeze the pressure wheel 16 when they come into contact with it, causing it to move.

[0025] The working principle of this practical application is as follows:

[0026] When braking, the telescopic hydraulic cylinder 6 can be moved by activating the movable hydraulic cylinder 7. The movement of the telescopic hydraulic cylinder 6 drives the L-shaped plate 5 and the movable plate 9 to move. The movement of the movable plate 9 drives the first inclined block 17 to move. The first inclined block 17 presses the left pressure wheel 16 to move. The movement of the left pressure wheel 16 drives the left rotating rod 15 and the left movable block 14 to move, thereby causing the two reset rods 11 to move, which in turn causes the left arc-shaped brake pad 4 to move. When the second pressure wheel 16 contacts the third inclined block 20, the left pressure wheel 16 separates from the first inclined block 17 and contacts the side of the first straight block 18. At this time, the left arc-shaped brake pad 4 contacts the brake disc 2 to brake.

[0027] At this time, the moving hydraulic cylinder 7 is closed and the telescopic hydraulic cylinder 6 is activated. The output shaft of the telescopic hydraulic cylinder 6 extends and retracts, so that the moving plate 9 continues to move. The pressure roller 16 on the left moves on the first straight block 18. The sides of the first straight block 18 and the second straight block 21 are parallel to the inner walls of both sides of the U-shaped plate 3, so that the left arc-shaped brake pad 4 does not move. The pressure roller 16 on the right is squeezed by the third inclined block 20, so that the right pressure roller 16, the rotating rod 15, the movable block 14 and the two reset rods 11 move, thereby making the right arc-shaped brake pad 4 approach the brake disc 2. When the pressure roller 16 on the left separates from the first straight block 18, the pressure roller 16 on the right contacts the second straight block 21. At the same time, the right arc-shaped brake pad 4 contacts the brake disc 2 for braking. When the arc-shaped brake pad 4 moves, the spring 13 will deform. When the pressure roller 16 on the left corresponds to the second inclined block 19, the arc-shaped brake pad 4 moves in the opposite direction under the left and right sides of the spring 13.

[0028] When the pressure roller 16 on the right side reaches the edge of the second straight block 21, the output shaft of the telescopic hydraulic cylinder 6 retracts, thereby causing the two arc-shaped brake pads 4 to alternately brake the brake disc 2, reducing the wear on the arc-shaped brake pads 4.

[0029] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are 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.
