Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of conveyors, and in particular to a belt conveyor braking device. Background Technology
[0002] A belt conveyor, also known as a rubber belt conveyor or belt conveyor, is a continuous conveying machine that uses friction to drive and utilizes a continuously moving conveyor belt as the traction and load-bearing component.
[0003] Existing belt conveyor braking devices include a fixed base, a motor, a bidirectional screw, a first brake, and a second rotating component. The fixed base has a groove, within which the bidirectional screw is positioned and connected to the motor. The first and second brakes are threadedly connected to the bidirectional screw. The first and second rotating components are located on the outer sides of the belt conveyor's drive shaft. In operation, the motor drives the bidirectional screw to rotate, which in turn moves the first and second brakes in opposite directions, clamping the belt conveyor's drive shaft. In this type of belt conveyor braking device, the braking force is transmitted from the motor to the bidirectional screw, then from the screw to the bottom of the first and second brakes, and finally to the belt conveyor's drive shaft. Furthermore, the braking effect is poor because it relies solely on clamping the drive shaft surface.
[0004] In the process of implementing this embodiment, the inventors discovered at least the following problems:
[0005] The existing braking devices for belt conveyors have poor braking performance. Utility Model Content
[0006] The purpose of this invention is to provide a braking device for belt conveyors, which solves the technical problem of poor braking effect in existing belt conveyor braking devices.
[0007] Utility model solution:
[0008] This utility model provides a braking device for a belt conveyor, including a drive shaft, a limiting disc, a fixed seat, and a braking assembly; the limiting disc is bolted to the drive shaft; the limiting disc has a limiting groove; the fixed seat is disposed on one side of the limiting disc; the braking assembly includes a pusher, a mounting cover, a brake disc, several brake pads, a disc spring, and a boss; the mounting cover is fixedly installed on the fixed seat; the pusher is installed on the mounting cover; the brake disc is drivenly connected to the pusher and has several cylindrical parts; the boss is slidably connected to the cylindrical parts, and the outer diameter of the boss is larger than the outer diameter of the limiting groove; the disc spring is disposed between the boss and the brake disc; the brake pads are installed on the brake disc.
[0009] Furthermore, the fixing base is provided with a sliding groove, and the mounting cover is adapted to the sliding groove.
[0010] Furthermore, the mounting base is equipped with a protective cover.
[0011] Furthermore, the brake disc is provided with a limiting post, and the disc spring is provided with a circular groove, which is adapted to the limiting post.
[0012] Furthermore, the limiting plate is provided with an inclined groove, and the boss is provided with an inclined portion, which is adapted to the inclined groove.
[0013] Beneficial effects:
[0014] This invention provides a braking device for a belt conveyor. In an emergency, the pusher pushes the brake disc, and the protrusion on the brake disc inserts into the limiting groove, engaging in friction braking within the limiting disc. Simultaneously, the brake pads abut against the surface of the limiting disc, also engaging in friction braking. The braking force is directly transmitted to the limiting disc, improving the limiting effect. Furthermore, multi-directional limiting further enhances the limiting effect. Therefore, this belt conveyor braking device offers superior braking performance. Attached Figure Description

[0031] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0032] This embodiment provides a belt conveyor braking device. Please refer to [link / reference]. Figure 1-5 As shown, the assembly includes a drive shaft 100, a limiting disc 200, a fixed base 300, and a braking assembly 400. The limiting disc 200 is bolted to the drive shaft 100. The limiting disc 200 has a limiting groove 210. The fixed base 300 is located on one side of the limiting disc 200. The braking assembly 400 includes a pusher 410, a mounting cover 420, a brake disc 430, several brake pads 440, a disc spring 450, and a boss 460. The mounting cover 420 is fixedly mounted on the fixed base 300. The pusher 410 is mounted on the mounting cover 420. The brake disc 430 is drivenly connected to the pusher 410 and has several cylindrical parts 431. The boss 460 is slidably connected to the cylindrical parts 431, and the outer diameter of the boss 460 is larger than the outer diameter of the limiting groove 210. The disc spring 450 is located between the boss 460 and the brake disc 430. The brake pads 440 are mounted on the brake disc 430.
[0033] Specifically, the drive shaft 100 is the output shaft of the belt conveyor. The drive shaft 100 has threaded holes. The limiting disc 200 is connected to the drive shaft 100 by five bolts. The limiting disc 200 extends the braking range of the drive shaft 100. As the boss 460 gradually penetrates deeper into the limiting groove 210, the limiting force on the limiting disc 200 increases. The fixed seat 300 is used to install the braking assembly 400. The braking assembly 400 is used to limit the limiting disc 200, thereby limiting the drive shaft 100. The pusher 410... Power is provided to the brake disc 430. The mounting cover 420 protects the brake disc 430 and also limits its movement. Four brake pads 440 are provided for friction braking of the limiting disc 200. A disc spring 450 allows the boss 460 to extend and retract axially. The extendable boss 460 ensures that both the boss 460 and the brake pads 440 simultaneously brake the limiting disc 200. The cylindrical member 431 ensures that the boss 460 can only move axially and not radially. In an emergency, the pusher 410 pushes the brake disc 430, and the boss 460 on the brake disc 430 inserts into the limiting groove 210, frictionally braking the inside of the limiting disc 200. Simultaneously, the brake pads 440 abut against the surface of the limiting disc 200, frictionally braking the surface of the limiting disc 200. The braking force is directly transmitted to the limiting disc 200, improving the limiting effect. Multi-directional limiting further enhances the limiting effect.
[0034] In this embodiment, the fixed base 300 is provided with a sliding groove 310, and the mounting cover 420 is adapted to the sliding groove 310.
[0035] Specifically, the slide groove 310 is designed to position the mounting cover 420 for installation, making it convenient for operators to install the mounting groove onto the fixed base 300.
[0036] In this embodiment, the fixing base 300 is provided with a protective cover 320.
[0037] Specifically, the protective cover 320 is designed to protect the limit plate 200.
[0038] In this embodiment, the brake disc 430 is provided with a limiting post 432, and the disc spring 450 is provided with a circular groove 451, which is adapted to the limiting post 432.
[0039] Specifically, the limiting post 432 and the circular groove 451 are used to limit the running trajectory of the disc spring 450.
[0040] In this embodiment, the limiting plate 200 is provided with a sloping groove 220, and the boss 460 is provided with an inclined portion 461, which is adapted to the sloping groove 220.
[0041] Specifically, the design of the inclined groove 220 and the inclined portion 461 increases the contact area between the boss 460 and the limiting disc 200, thereby improving the braking effect of the limiting disc 200.
[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
