[0031] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0032] Example 1:

[0033] See Figure 1-3 A conveyor brake includes a steel frame 10, with a docking seat 11 installed at one end of the steel frame 10 and bearing seats 20 installed on both sides of the other end. The central shafts 30 at both ends of the belt roller 40 are respectively connected to the bearing seats 20 on both sides. One or both ends of the central shaft 30 extend out of the bearing seats 20, and a brake element 60 is installed on the extended end of the central shaft 30. A support plate 12 is installed on the steel frame 10 at the position corresponding to the brake element 60. A brake 70 is installed on the support plate 12. The brake 70 cooperates with the brake element 60 to brake the belt roller 40.

[0034] The docking seat 11 is used to dock with the driven end of the conveying unit, see [reference]. Figure 1 , 2 The docking seat 11 can adopt a pin connection structure, that is, the docking seat 11 is a hinged lug seat. In this embodiment, four docking seats 11 are provided. The belt of the conveying unit is mounted on the drive roller of the conveying unit and the belt roller 40 of the brake section. The belt roller 40 is mounted on the bearing seat 20 through the central shaft 30, so that the belt roller 40 can be driven to rotate. A brake element 60 is installed on the central shaft 30 of the belt roller 40 of the brake section, and a brake element 70 is installed on the steel frame 10. The brake 70 cooperates with the brake element 60. When the concrete conveying system stops in an emergency, the brake 70 and the brake element 60 cooperate to brake the belt roller 40, so that the belt can stop quickly to prevent concrete accumulation and damage to the drive device.

[0035] See Figure 2 The steel frame 10 includes an extended end 13 and a docking end 14. The height of the extended end 13 is smaller than the height of the docking end 14. A docking seat 11 is installed on the docking end 14, and a belt roller 40 is installed on the extended end 13. This structure facilitates docking between multiple conveying units. During docking, the drive section of the next conveying unit is placed below the brake section of the previous conveying unit.

[0036] In one embodiment, the brake element 60 is a brake drum, and the brake 70 is a drum brake. The brake drum can be directly mounted on the central shaft 30.

[0037] In this embodiment, see Figure 2 The braking component 60 is a brake disc, and the brake 70 is a disc brake.

[0038] To facilitate the installation of the brake disc, the brake disc is mounted on the central shaft 30 via coupling 80.

[0039] In one embodiment, coupling 80 is half of a flange coupling, which is fixedly mounted on the central shaft 30, and the brake disc is bolted to the flange of the flange coupling.

[0040] Furthermore, since the belt roller 40 is mounted on the bearing housing 20 via the central shaft 30, and the bearing in the bearing housing 20 needs to be replaced when it is damaged, the brake disc and coupling 80 need to be removed when replacing it. However, the flange coupling is generally mounted on the central shaft 30 with an interference fit, so it is inconvenient to disassemble the flange coupling during maintenance.

[0041] Therefore, in the preferred embodiment, see Figure 4 , 5 6. The coupling 80 includes an inner ring 81, a retaining ring 82, and a clamping ring 83. The outer circumference of the inner ring 81 is provided with inclined surfaces 811 at both ends. The inner ring 81 is provided with a notch 812 along the axial direction. There are two clamping rings 83. The inner circumference of the clamping ring 83 is provided with a fitting surface that fits with the inclined surface 811. The retaining ring 82 is fitted in the middle of the inner ring 81. The two clamping rings 83 are respectively fitted on the inclined surfaces 811 at both ends of the inner ring 81. Multiple limiting screws 84 pass through the clamping ring 83 and the retaining ring 82 on one side and then screw into the clamping ring 83 on the other side. The brake disc is installed on the retaining ring 82 by connecting bolts 85. The inner ring 81 is fitted on the central shaft 30.

[0042] During installation, first pre-assemble the inner ring 81, retaining ring 82, and clamping ring 83. Without tightening the limiting screw 84, the inner ring 81, with an axial notch 812, can easily fit onto the central shaft 30. Then tighten the limiting screw 84. When tightening the limiting screw 84, the mating surface of the clamping ring 83 presses against the inclined surface 811, and the inner ring 81, under the pressure of the clamping rings 83 on both sides, tightly grips the central shaft 30. At the same time, the clamping rings 83 on both sides also clamp and fix the retaining ring 82. Afterward, install the brake disc onto the retaining ring 82 using the connecting bolt 85. When it is necessary to replace the bearing, loosen the limiting screw 84 to easily remove the inner ring 81 for easy bearing replacement.

[0043] Example 2:

[0044] Based on Embodiment 1, at least one idler roller unit 50 is installed on the steel frame 10 in the area between the docking seat 11 and the belt roller 40 to improve the support effect on the belt.

[0045] In this embodiment, see Figure 7 The roller unit 50 includes multiple rollers 51. A roller 511 is rotatably mounted at the center of each roller 51 via a bearing. The rollers 511 between adjacent rollers 51 are movably connected by a first fastener 512. A tie rod 52 is movably connected to the rollers 511 at both ends of the roller unit 50 via a second fastener 513. Mounting plates 15 are fixedly connected to both sides of the steel frame 10, and the tie rods 52 are fixedly mounted to the mounting plates 15.

[0046] Specifically, each end of the roller 511 has a hinge hole, and the first fastener 512 connects to the two hinge holes on the adjacent roller 511. Similarly, one end of the pull rod 52 has a hinge hole, and the second fastener 513 connects to the hinge hole on one end of the pull rod 52 and the roller 511 of the idler unit 50. The other end of the pull rod 52 passes through the hole on the mounting plate 15 and is then fixed by the positioning element 521. The positioning element 521 can be a nut or a pin. Of course, the pull rod 52 can also be welded to the mounting plate 15.

[0047] Preferably, the first fastener 512 and the second fastener 513 can be pins or bolts.
