[0002] In the mining process, materials are usually transported by belt conveyors to improve production efficiency.

[0003] A belt conveyor typically consists of a frame, a conveyor roller assembly, and a belt. The conveyor roller assembly is mounted on the frame, and the belt is sleeved over the conveyor roller assembly. Due to prolonged, intensive use, the belt may wear, age, or break, necessitating replacement. During belt replacement, the weight of the belt itself can cause it to slip or move rapidly along the conveyor roller assembly, compromising smooth belt replacement.

[0004] Typically, when installing or replacing a belt, after the belt is placed on the conveyor roller assembly, it is temporarily secured to the frame by bundling to prevent the belt from slipping or moving rapidly. However, bundling the belt to the frame is less convenient. Utility Model Content

[0033] 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. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. 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.

[0034] like Figure 1 and Figure 2 As shown, the utility model provides a conveying device, which includes a frame 10, a conveying roller assembly, a belt 30 and a brake assembly; the conveying roller assembly includes a plurality of conveying roller bodies 21 spaced apart along the length direction of the frame 10, the plurality of conveying roller bodies 21 are parallel to each other, the conveying roller bodies 21 extend along the width direction of the frame 10, and the conveying roller bodies 21 are rotatably arranged on the frame 10; the belt 30 is sleeved on the plurality of conveying roller bodies 21 of the conveying roller assembly; the brake assembly includes a driving part and a braking part, the braking part is located above the belt 30, the braking part can be raised and lowered relative to the belt 30, the driving part drives the braking part to rise and fall, the braking part has an avoidance position and a braking position, when the braking part is in the avoidance position, there is a gap between the braking part and the top surface of the belt 30; when the braking part is in the braking position, the braking part cooperates with at least one conveying roller body 21 to clamp the belt 30.

[0035] By applying the technical solution of the present invention, the belt 30 of the conveying device is sleeved on multiple conveying roller bodies 21. When the conveying device is in the normal operating stage, the multiple conveying roller bodies 21 rotate to drive the belt 30 to move, and the braking part is in the avoidance position. There is a gap between the braking part and the top surface of the belt 30, and the braking part will not interfere with the movement of the belt 30; when the belt 30 is replaced or an emergency occurs and the belt 30 needs to be stopped quickly, the braking part is driven down by the driving part of the brake assembly, so that the braking part cooperates with the conveying roller body 21 to clamp the belt 30, which can quickly, conveniently and reliably stop the belt 30 and prevent the belt 30 from slipping or moving quickly, thereby improving the operational convenience and safety of the conveying device.

[0036] In the embodiment of this scheme, the frame 10 serves as the foundational structure of the entire conveyor device, providing a stable mounting platform for the conveyor roller assembly and brake assembly, and providing a support base for the stable movement of the belt 30. The conveyor roller assembly, through multiple parallel conveyor roller bodies 21, can support and guide the operation of the belt 30, ensuring smooth and continuous conveying of the belt 30 and improving the conveying efficiency of the conveyor device. The brake assembly can quickly respond in an emergency, lowering the brake unit through the drive unit to achieve emergency braking of the belt 30 to prevent the belt 30 from deviating or losing control. The brake unit can provide sufficient braking capacity to quickly stop the movement of the belt 30, thereby improving the safety and reliability of the conveyor device.

[0037] Furthermore, along the height direction of the frame 10 , at least part of the projection of the braking portion is located on the circumference of one of the conveyor roller bodies 21 . When the braking portion is in the braking position, the distance between the braking portion and the circumference of the conveyor roller body 21 is less than the thickness of the belt 30 .

[0038] In an embodiment of the present scheme, by designing the projection of at least part of the braking part onto the circumferential surface of one of the conveyor roller bodies 21, the physical distance between the braking part and the belt 30 is shortened, thereby reducing the braking response time of the braking part, making the braking part brake the belt 30 more quickly, thereby improving the braking efficiency and safety of the conveying device.

[0039] When the braking part is in the braking position, the distance between the braking part and the circumferential surface of the conveyor roller body 21 is less than the thickness of the belt 30, which means that the braking part can cooperate with the conveyor roller body 21 to stably clamp the belt 30 when in the braking position, producing a stable friction braking effect on the belt 30, thereby enhancing the reliability of the braking assembly.

[0040] like Figure 2 and Figure 3 As shown, further, the braking portion includes a braking roller 40 , and the extending direction of the braking roller 40 is the same as the extending direction of the conveying roller body 21 .

[0041] Specifically, when the brake unit brakes the belt 30, the brake roller 40 contacts the belt 30 and cooperates with the conveyor roller body 21 to squeeze the belt. The brake roller 40 and the conveyor roller body 21 extend in the same direction, meaning they form a consistent contact line on the belt 30. This ensures that the braking force of the brake roller 40 is evenly distributed across the width of the belt 30. This ensures a smooth transition from normal operation to braking, reduces the impact on the belt 30 during braking, improves the smoothness of the braking process, and reduces the risk of damage or deviation due to excessive local force on the belt 30.

[0042] like Figures 1 to 3As shown, further, when the brake roller 40 is in the braking position, the height of the bottom end of the brake roller 40 is lower than the height of the top end of the corresponding conveyor roller body 21, and the distance between the circumferential surface of the brake roller 40 and the circumferential surface of the conveyor roller body 21 is less than the thickness of the belt 30. In this configuration, the bottom end of the brake roller 40 is lower than the top end of the conveyor roller body 21, and the distance between the circumferential surfaces of the two is less than the thickness of the belt 30. This allows the brake roller 40 to more closely cooperate with the conveyor roller body 21 to clamp the belt in the braking state, generating a stronger friction force on the belt 30, thereby effectively preventing the movement of the belt and ensuring the braking effect.

[0043] In the embodiment of this solution, a plurality of braking parts are provided, and the plurality of braking parts are spaced apart along the length direction of the frame 10 , and each conveying roller body 21 cooperates with a braking part to brake the belt 30 .

[0044] In this embodiment, when the brake assembly brakes the belt 30, multiple braking components descend, and the multiple brake rollers 40 cooperate with corresponding conveyor roller bodies 21 to clamp the belt 30. This creates uniform braking force at multiple locations on the belt 30, quickly and smoothly stopping the belt 30 and improving the conveyor's braking efficiency. The coordinated action of the multiple braking components effectively brakes the belt 30 at multiple locations along its length, reducing the uneven force caused by single-point braking, improving the smoothness of the braking process, and extending the belt's service life.

[0045] Furthermore, multiple braking parts are raised and lowered synchronously. This arrangement enables multiple braking parts to contact the belt 30 simultaneously and produce a braking effect on the belt 30 at the same time, reducing the braking differences between the braking parts and improving the smoothness of the braking process. In addition, the synchronous raising and lowering of the multiple braking parts simplifies the complexity of the conveyor's brake control system and improves the controllability of the conveyor.

[0046] Furthermore, the conveying device further includes a connecting portion 50 , a plurality of braking portions are provided on the connecting portion 50 , the driving portion is drivingly connected to the connecting portion 50 , and the connecting portion 50 is liftably provided on the frame 10 .

[0047] In this solution, multiple braking parts are uniformly installed on a connecting part 50, and the connecting part 50 is arranged on the frame 10 in a liftable manner, so that all braking parts can be synchronously lifted and lowered relative to the frame 10 as a whole, reducing the inconsistency of response time and braking force of different braking parts, improving the uniformity and speed of braking response, and enhancing the braking efficiency of the conveying device.

[0048] Specifically, the driving part is connected to the connecting part 50. When the brake assembly needs to be raised or lowered, the driving part is started to drive the connecting part 50 to be raised or lowered on the frame 10. The connecting part 50 drives each brake assembly to be raised or lowered, thereby adjusting the position of the brake assembly.

[0049] In the embodiment of this solution, the connecting portion 50 includes a connecting plate 51 and guide rods 52. The connecting plate 51 extends along the length of the frame 10. Multiple brakes are spaced apart on the connecting plate 51 along the extension direction of the connecting plate 51. The top ends of the two guide rods 52 are respectively disposed at the ends of the length of the connecting plate 51. The guide rods 52 are arbitrarily mounted on the frame 10. It will be understood that the connecting plate 51 provides a stable mounting base for the multiple brakes, and the combination of the guide rods 52 and the frame 10 provides stable support for the normal operation of the brake assembly. Furthermore, this arrangement ensures that when the brake is in the avoidance position, there is sufficient spacing between the brake and the top of the belt to reduce or prevent interference between the brake and the material.

[0050] Furthermore, the frame 10 includes a support frame 11 and a guide plate 12. The conveyor roller body 21 is rotatably mounted on the support frame 11. Two guide plates 12 are provided, with the bottom ends of the two guide plates 12 disposed at the ends of the length of the support frame 11. The support frame 11 is provided in correspondence with a guide rod 52, which is movably mounted on the support frame 11 along the height direction. In the embodiment of this solution, the support frame 11 serves as the mounting base for the conveyor roller body 21, providing stable support for the normal operation of the conveyor roller body 21 and the belt 30. The provision of the guide plates 12 provides support for the raising and lowering of the guide rod 52.

[0051] Furthermore, guide grooves are provided on the longitudinal sides of the support frame 11, extending in the height direction. Guide blocks are provided on the sides of the guide rods 52, and are movably disposed within the guide grooves. The guide grooves and guide blocks cooperate to form a guide structure 60, which guides the raising and lowering of the guide rods 52.

[0052] During the braking process, under the driving action of the driving part, the guide rod 52 will move relative to the guide plate 12, and the guide rod 52 will move downward relative to the guide plate 12. The guide rod 52 drives the connecting plate 51 to move downward, and the connecting plate 51 then drives the braking part to move downward, thereby braking the conveying roller body 21.

[0053] When the belt 30 is no longer needed to be braked, the driving part is started again, driving the guide rod 52 to move upward relative to the guide plate 12, and the guide rod 52 drives the connecting plate 51 and multiple braking parts to rise, and the braking part returns to the avoidance position. The braking part no longer contacts the belt 30, and the conveying device returns to normal.

[0054] The coordinated use of the guide plate 12 and the guide rod 52 improves the stability and guiding accuracy of the connecting part 50 during the lifting process, makes the braking action of the braking part more stable, and enhances the stability of the braking process.

[0055] Furthermore, the guide structure 60 formed by the cooperation of the guide plate 12 and the guide rod 52 is arranged at the end of the conveying device in the length direction, thereby optimizing the overall layout of the conveying device.
