Embodiment Construction
[0024] The core of the present invention is to provide a belt tearing alarm system, which can alarm in time when an object penetrating the belt is stuck, so as to avoid further damage.
[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the belt tear alarm system of the present invention will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0026] Such as figure 2 As shown, it is a structural schematic diagram of the belt tearing alarm system of the present invention; the present invention provides a belt tearing alarm system, including structures such as a buffer supporting bed 1 and a displacement alarm 4, wherein the buffer supporting bed 1 is arranged on the conveyor belt 2 Below, and aligned with the outlet of the discharge pipe 3, the discharge pipe 3 is vertically arranged, the coal material falls from top to bottom, and falls on the c...

The invention discloses a belt tear alarm system. The belt tear alarm system comprises such structures as a buffer support bed and a displacement alarm, wherein the buffer support bed is arranged below a conveying belt, and is aligned to a discharge port of a blanking pipe; the impact during falling of coals is borne through the buffer support bed; when the belt is punctured by a hard object to downwards extend, the belt can be blocked at the top of the buffer support bed, and the buffer support bed can be pulled to horizontally move by the object which punctures the conveying belt; the displacement alarm is used for detecting displacement of the buffer support bed, and is in signal connection with a control device; the horizontal movement of the buffer support bed can be detected by the displacement alarm during horizontally moving; and when the displacement of the buffer support bed exceeds a preset value, an alarm is given to notify operators to stop the machine or to automaticallystop the machine, so that the conveying belt is prevented from continuously moving forwards to be scratched by the hard object to form a larger gap.
Description
technical field [0001] The invention relates to the technical field of belt conveyors, and further relates to a belt tearing alarm system. Background technique [0002] The coal conveying system of a thermal power plant uses a belt conveyor to transport the raw coal to the boiler for treatment and then burns it. Iron parts and other materials in the raw coal can easily pierce the belt. If the belt conveyor cannot be detected and stopped in time, the belt may be severely torn. crack, causing huge economic losses. [0003] Such as Figure 1A Shown is the side view of the current conventional belt breakage alarm device, the belt moves from left to right; as Figure 1B As shown, it is the front view of the current conventional belt breakage alarm device, that is, facing the direction of belt running; Figure 1C Shown is the alarm structure diagram of the current conventional belt breakage alarm device, shown in the figure is the view facing the belt conveying direction; the co...
