Description

Technical Field

[0001] The utility model relates to the technical field of conveyor belts for cement production, and particularly relates to an anti-tearing device for a conveyor belt. Background Art

[0002] In the cement production industry, belt conveyors are involved in transporting limestone, clinker, raw coal, etc. It can be said that the belt conveyor is the lifeline of cement production. Since foreign objects are inevitably mixed into the materials during the operation of raw materials and equipment, once the belt is damaged by foreign objects and the on-site post and central control fail to detect it in time, it will have a fatal impact on production. In the prior art, there is a solution to replace the conventional belt with an anti-tearing belt, but the production cost of this belt is high and it cannot be widely used. Therefore, it is necessary to develop an anti-tearing device for a conveyor belt that can effectively protect the belt and has a low cost. Content of the Utility Model

[0003] To solve the above technical problems, the utility model can protect the belt and avoid large-area tearing of the belt after the belt is torn by foreign objects, and minimize the loss. The specific technical solutions are as follows:

[0004] An anti-tearing device for a conveyor belt includes a bracket arranged on the belt tail frame, and further includes:

[0005] A driving component, the driving component is arranged on the bracket, and the driving component can rotate along the bracket under the drive of the falling material when the belt is torn; and

[0006] A triggering component, the triggering component can trigger the belt to stop when the driving component rotates.

[0007] Preferably, the driving component is distributed parallel to the belt when the belt is running normally.

[0008] Preferably, the driving component includes a counterweight rod rotatably arranged on the bracket, a material receiving box arranged at one end of the counterweight rod, and a counterweight block arranged at the other end of the counterweight rod.

[0009] Preferably, the weight of the counterweight block is equal to the mass of the empty material receiving box.

[0010] Preferably, the counterweight rod is rotatably connected to the bracket through a rotary support seat arranged in the middle thereof.

[0011] Preferably, the triggering component is a sensor, and the sensor is also electrically connected to a belt deviation switch, and can trigger the belt deviation switch to act to realize belt stop when the counterweight block rotates.

[0012] As can be seen from the above technical solutions, the utility model has the following beneficial effects: The driving assembly is arranged on the bracket. During the normal operation of the belt, the material receiving box and the counterweight are in a balanced state at this time. When the belt tears, the material on the belt drops into the material receiving box. At this time, the balance between the material receiving box and the counterweight is broken, and the counterweight rotates under the drive of the counterweight rod. The triggering assembly senses the displacement of the counterweight and controls the belt to trip through the belt deviation switch to achieve the protection of the belt.

[0018] The following will combine the drawings and specific embodiments to detail the present utility model. Before detailing the technical solutions of each embodiment of the present utility model, the nouns and terms involved will be explained. In this specification, components with the same name or the same reference numeral represent similar or the same structures, and are for illustrative purposes only.

[0019] Refer to Figure 1 、 Figure 2 , a conveyor belt anti-tearing device, including a bracket 10, a driving assembly 20 and a triggering assembly arranged on the belt tail rack. The driving assembly 20 is arranged on the bracket 10, and the driving assembly 20 can rotate along the bracket 10 under the drive of the dropped material when the belt tears. When the driving assembly 20 rotates along the bracket, it will drive the triggering assembly to act, and the triggering assembly will then control the conveyor belt to trip, so as to stop running in time when the belt tears, play a role in protecting the belt, avoid large-area tearing of the belt, and minimize the loss.

[0020] As a preferred technical solution of the present utility model, the driving assembly 20 is distributed parallel to the belt when the belt is running normally. In this way, when the belt is torn, the material can fall from the torn part onto the driving assembly, so that the driving assembly can be actuated, and then drive the trigger assembly to actuate to control the conveyor belt to trip.

[0021] Of course, it should be noted that the driving assembly 20 in the present utility model is not limited to being arranged parallel to the belt. For example, the driving assembly 20 can also be arranged obliquely to the belt, as long as it satisfies that the material falling from the belt when the belt is torn can drive the driving assembly to rotate to actuate with the trigger assembly.

[0022] Refer to Figure 3 Furthermore, the driving assembly 20 includes a counterweight rod 210, a material receiving box 220, and a counterweight 230. The counterweight rod 210 is rotatably arranged on the bracket 10. The material receiving box 220 is arranged at one end of the counterweight rod 210, and the counterweight 230 is arranged at the other end of the counterweight rod 210. Since the weight of the counterweight 230 is equal to the mass of the empty material receiving box 220, in this way, when the belt is not torn, the material receiving box 220 and the counterweight 230 on both sides of the counterweight rod 210 are in a balanced state. At this time, the trigger assembly cannot trigger the conveyor belt to trip under the drive of the driving assembly. When the belt is torn, the material on the belt falls on the material receiving box 220. As the material entering the material receiving box 220 increases, the material receiving box 220 and the counterweight 230 lose balance. Driven by the material receiving box 220 and the material, the counterweight 230 rotates, and the counterweight 230 then senses with the trigger assembly, and the trigger assembly then controls the conveyor belt to trip to realize the protection of the belt.

[0023] Furthermore, in order to realize the rotation of the counterweight rod 210 relative to the bracket 10, a rotating support seat 240 is arranged in the middle of the counterweight rod 210. The counterweight rod 210 is rotatably connected to the bracket 10 through the rotating support seat 240, thereby realizing the free rotation of the counterweight rod 210.

[0024] As a preferred technical solution of the present utility model, the trigger assembly is specifically a sensor 30. Specifically, the sensor 30 can be arranged on the belt rack, and the sensor 30 is also electrically connected to a belt deviation switch. The sensor 30 can sense the displacement of the counterweight 230 when the counterweight 230 rotates, so as to trigger the belt deviation switch to actuate, thereby realizing the tripping of the belt.

[0025] During use, refer to Figure 4, the driving component 20 is arranged on the bracket 10. During the normal operation of the belt, the material receiving box 220 and the counterweight 230 are in a balanced state at this time. When the belt tears, the materials on the belt fall into the material receiving box 220. At this time, the balance between the material receiving box 220 and the counterweight 230 is broken, and the counterweight 230 rotates under the drive of the counterweight rod 210. The triggering component senses the displacement of the counterweight 230 and controls the belt to trip through the belt deviation switch to realize the protection of the belt.

[0026] The above-described embodiments are only descriptions of the preferred embodiments of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
