Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a conveyor belt longitudinal tear detection device. Background Art

[0002] Belt conveyors are widely used in industry, mainly composed of the conveyor belt, which is the key part of conveying materials, and the frame that supports its operation. However, this kind of equipment may encounter two situations during long-term operation. First, the conveyor belt may tear longitudinally, causing the material being conveyed to spill on the belt below; second, the material may penetrate the conveyor belt. Both situations may bring uncertainty to the stable operation of the conveyor and even cause serious safety accidents.

[0003] In addition, the tear detection equipment in the prior art is limited in function and does not have the ability to detect materials penetrating the conveyor belt. When the conveyor belt is torn longitudinally and materials fall, these materials can only be detected if they fall directly on the tear detection device. This detection method is not ideal and has great limitations. Utility Model Content

[0017] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0018] like Figure 1-Figure 3The conveyor belt longitudinal tear detection device of the utility model shown in the figure includes a tear trigger 7, an upper baffle 2 and a lower baffle 3 are arranged between the upper and lower belts of the conveyor belt, the upper baffle 2 and the lower baffle 3 are distributed in the vertical direction, a rotating rod 4 rotatably connected to the frame of the conveyor belt is arranged between the upper baffle 2 and the lower baffle 3, the upper baffle 2 and the lower baffle 3 are fixedly connected by the rotating rod 4, a trigger plate 6 is fixedly provided on the rotating rod 4, and the trigger plate 6 is located in the groove 13 of the trigger rod 10 of the tear trigger 7 at one end away from the rotating rod 4.

[0019] The tear trigger 7 includes a housing 8, in which an optical switch sensor 12 and a trigger rod 10 adapted to the optical switch sensor 12 are arranged. One end of the trigger rod 10 passes through the housing 8 and extends to the outside of the housing 8. A groove 13 is provided on the front side wall of the trigger rod 10 located outside the housing 8. The trigger rod 10 is also sleeved with a spring 9 fixed to the outer side wall of the housing 8. The trigger plate 6 on the rotating rod 4 is separated from the groove 13 and is located outside the groove 13. Under the action of the spring 9, the trigger rod 10 retracts and triggers the optical switch sensor 12, so that the tear trigger 7 sends a light signal to notify the staff to repair the conveyor belt. By arranging a moving bar 11 located outside the housing 8 on the trigger rod 10, the moving bar 11 can facilitate the staff to move the trigger rod 10 back to the initial position, and make the trigger plate 6 away from the end of the rotating rod 4 return to the groove 13 of the trigger rod 10 of the tear trigger 7. By sleeved two vertical plates 1 fixedly connected to the frame of the conveyor belt on the outer side wall of the rotating rod 4, the rotating rod 4 is rotatably connected to the frame of the conveyor belt through the vertical plates 1, and the upper baffle 2 and the lower baffle 3 are both located between the two vertical plates 1, and the vertical plates 1 can be used to improve the stability of the device during use. By setting the trigger plate 6 on one end of the rotating rod 4, it can be convenient for the staff to use the device, and avoid the material directly falling on the tear trigger 7 when the conveyor belt is longitudinally torn or punctured, thereby damaging the tear trigger 7. By sleeved a flip welding support 5 on the outer side wall of the rotating rod 4, the upper baffle 2 and the lower baffle 3 are fixed to the rotating rod 4 through the flip welding support 5, and the flip welding support 5 can be used to improve the stability of the device during use. By fixing a detection device chassis fixedly connected to the frame of the conveyor belt at the bottom of the vertical plate 1, the detection device chassis can be used to improve the stability of the vertical plate 1 during use.

[0020] Combined with Figure 1-3It can be seen that the method of using the utility model is as follows: first, if the upper belt of the conveyor belt is torn longitudinally, the conveyed material falls onto the lower belt of the conveyor belt, and will move with the lower belt of the conveyor belt and come into contact with the lower baffle 3, so that the lower baffle 3 drives the rotating rod 4 and the upper baffle 2 to rotate on the vertical plate 1 through the flip welding support 5, driving the trigger plate 6 on the rotating rod 4 to disengage from the groove 13 and be located outside the groove 13. Under the action of the spring 9, the trigger rod 10 retracts and triggers the optical switch sensor 12, so that the tearing trigger 7 sends out a light signal to notify the staff that the conveyor belt is torn longitudinally. If the upper belt of the conveyor belt is punctured by the material, the material penetrating the upper belt of the conveyor belt will As the conveyor belt moves and contacts the upper baffle 2, the upper baffle 2 drives the rotating rod 4 and the lower baffle 3 to rotate via the flip welding support 5, driving the trigger plate 6 on the rotating rod 4 to disengage from the groove 13 and be located outside the groove 13. Under the action of the spring 9, the trigger rod 10 retracts and triggers the optical switch sensor 12, thereby turning on the optical switch sensor 12, causing the tear trigger 7 to emit a light signal to notify the staff that the conveyor belt is punctured. After the staff completes the maintenance or cleaning of the conveyor belt, they move the trigger rod 10 back to the initial position through the moving lever 11, and make the trigger plate 6 away from the end of the rotating rod 4 return to the groove 13 of the trigger rod 10 of the tear trigger 7.
