Carrier roller abrasion alarm device

Abstract

The utility model relates to a carrier roller abrasion alarm device, and belongs to the technical field of surface mine safety facilities. According to the technical scheme, a coil (3) is wound on the inner wall of a carrier roller pipe body (1), a weftless tape (2) is pasted on the inner layer of the coil (3), and the coil (3) is connected with a circuit break alarm (4). The carrier roller has the advantages that the weftless tape is adhered to the inner layer of the coil and sprayed with the insulating paint, the weftless tape plays a role in insulation, supporting and protection, and when the carrier roller pipe body is damaged, the coil is abraded to cause open circuit, and the open circuit alarm starts to give an alarm and buzz to remind post workers to replace the carrier roller, so that a belt is prevented from being scratched.

Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of idler wear alarm device, belong to open-pit mine safety facilities technical field. BACKGROUND

[0002] Idler is the important component of belt conveyor, can support the weight of conveying belt and material. It accounts for 35% of the total cost of a belt conveyor, generates more than 70% resistance. Due to this characteristic, the idler will wear out even the idler tube body will be worn out after a period of use, and the burr of the damaged tube body will scratch the belt, leading to the consumption of equipment cost. The idler used by a long transport belt can reach hundreds or thousands, and the post personnel must check the use condition of each idler every day to prevent the idler tube body from damaging the belt. Therefore, it greatly increases the labor of post personnel, and there is a possibility of missed detection. Therefore, it is urgent to design a device that can detect idler wear and alarm. SUMMARY

[0003] The utility model aims at providing a kind of idler wear alarm device, by pasting no-warp tape in the inner layer of coil and spraying insulating paint, the no-warp tape plays the role of insulation, support and protection. When the idler tube body is damaged, the coil is broken, causing a short circuit, and the short-circuit alarm starts to alarm, reminding the post staff to replace the idler, to avoid scratching the belt, effectively solving the above problems existing in the background art.

[0004] The technical scheme of the utility model is: a kind of idler wear alarm device, including idler tube body, no-warp tape, coil and short-circuit alarm, the coil is wound on the inner wall of idler tube body, the no-warp tape is pasted in the inner layer of coil, and the coil is connected with short-circuit alarm.

[0005] The coil is evenly wound on the inner wall of idler tube body.

[0006] The no-warp tape is sprayed with insulating paint.

[0007] The utility model has the beneficial effects that: by pasting no-warp tape in the inner layer of coil and spraying insulating paint, the no-warp tape plays the role of insulation, support and protection. When the idler tube body is damaged, the coil is broken, causing a short circuit, and the short-circuit alarm starts to alarm, reminding the post staff to replace the idler, to avoid scratching the belt. BRIEF DESCRIPTION OF DRAWINGS

[0008] Figure 1 It is the structure schematic drawing of the utility model;

[0009] In the figure: idler tube body 1, no-warp tape 2, coil 3, short-circuit alarm 4, shaft center 5. DETAILED DESCRIPTION

[0010] In order to make the utility model embodiment purposes, technical solutions and advantages more clearly, below will combine the drawings in the embodiment, the technical solutions in the embodiment of the utility model will be clearly and completely described, obviously, the embodiment expressed is a small part of the embodiment of the utility model, not all the embodiment, all other embodiments obtained by the person skilled in the art without making the premise of creative labor based on the embodiment in the utility model, belong to the protection scope of the utility model.

[0011] A kind of carrier roller wear alarm device, including carrier roller tube body 1, no weft tape 2, coil 3 and open circuit alarm 4, the coil 3 is wound in the inner wall of carrier roller tube body 1, no weft tape 2 is pasted in the inner layer of coil 3, coil 3 is connected with open circuit alarm 4.

[0012] The coil 3 is evenly wound in the inner wall of carrier roller tube body 1.

[0013] The no weft tape 2 is sprayed with insulating paint.

[0014] In practical application, coil 3 is evenly wound in the inner wall of carrier roller tube body 1, no weft tape 2 is pasted in the inner layer of coil 3 and is sprayed with insulating paint, and no weft tape 2 can play the role of insulation, support and protection.When carrier roller tube body 1 is damaged, the conveying belt starts to rub coil 3, when coil 3 is rubbed off and causes open circuit, open circuit alarm 4 starts to alarm and buzz, reminding post workers to replace carrier roller. Thus, the problem of scratching belt due to not timely replacing damaged carrier roller is completely solved.
