It is mainly used in flammable and explosive environments such as coal mines. To ensure safety during actual use, it is also necessary to ensure the conductivity of the conveyor belt to avoid potential safety hazards caused by static electricity. Currently, the existing antistatic aramid fabric solid-core flame-retardant conveyor belt is not convenient for anti-breakage and fallback protection.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Embodiment 1: Please refer to Figures 1 to 10 as shown: The present invention provides a technical solution: an antistatic aramid fabric integrally cored flame-retardant conveyor belt, which includes a conveying connector 1, on which a vulcanized joint test piece 2 is installed for detecting the quality of the vulcanized joint; two circles of anti-disengagement hanging pieces 3 are installed on the conveying connector 1; the two circles of anti-disengagement hanging pieces 3 are used for hanging on the idler rollers; one-way limiting pieces 4 are respectively installed on the two circles of anti-disengagement hanging pieces 3, and the one-way limiting pieces 4 are used for limiting the anti-disengagement hanging pieces 3; a segmented detection piece 5 is installed on the conveying connector 1; the segmented detection piece 5 is used for detecting pulling and shaking; the conveying connector 1 includes: a rubber conveyor belt 101 and an indicator light 1011, and a circle of indicator lights 1011 is fixedly installed on the side of the rubber conveyor belt 101.

[0022] Among them, the conveying connection member 1 further includes: an aramid fabric layer 102 and an electrostatic elimination coating 103.

Two joint embedding blocks 201 are fixedly embedded at both ends of the rubber conveyor belt 101, and test guide wires 202 are fixedly installed on the two joint embedding blocks 201 respectively, and the four test guide wires 202 pass through the rubber conveyor belt 101 respectively; the joint embedding blocks 201 at both ends of the rubber conveyor belt 101 are aligned; after the rubber conveyor belt 101 and the aramid fabric layer 102 are joined by hot vulcanization at the head and tail, the two opposite joint embedding blocks 201 are attached to each other. Using the conveying connection member 1 can facilitate flame retardant protection. At the same time, this structure can be grounded by using the conductive wires 1031, which can improve the anti-static grounding effect of this structure and enhance the use safety. Through the vulcanized joint test piece 2, it is convenient for the staff to understand the quality of the rubber conveyor belt 101 joint without damaging the joint quality of the rubber conveyor belt 101, and avoid the situation that the inside of the rubber conveyor belt 101 falls off and is not discovered, which can improve the use safety of this structure. This structure can also facilitate ensuring the joint fit when performing hot vulcanization joint work. Otherwise, the joint embedding blocks 201 cannot be attached to each other. The inspector can directly check, and the operation is simple and convenient, which improves the stability after the head and tail of the rubber conveyor belt 101 are joined and avoids the problem that hidden cracks are not easy to check. The staff can use a multimeter to detect whether there is an open circuit problem with the two test guide wires 202 on the same side. Once there is an open circuit, it means that the two joint embedding blocks 201 are no longer attached to each other, that is, there is a crack. The staff can observe regularly. As the rubber conveyor belt 101 conveys and moves, the counterweight ball 104 can be in contact with the ground for grounding in real time.

[0023] Among them, the anti - detachment and hanging component 3 includes: a connecting steel sheet 301 and a positioning pin 302. The connecting steel sheet 301 is inserted and installed on the rubber conveyor belt 101; the positioning pin 302 is fixedly inserted on the connecting steel sheet 301 and the positioning pin 302 is inserted into the rubber conveyor belt 101; the anti - detachment and hanging component 3 further includes: a rotary seat 303 and a hook 304.

The one - way limiting block 401 is rotatably installed on the hook 304; the one - way limiting block 401 is a bevel - shaped structure; the bottom of the one - way limiting block 401 is fixedly installed with the connecting elastic sheet 402 and the connecting elastic sheet 402 is a V - shaped structure; the end of the connecting elastic sheet 402 is fixedly installed with the limiting plate 4021 and the limiting plate 4021 is fixedly installed on the inner side of the hook 304. When the rubber conveyor belt 101 is normally moving and conveying, the anti - detachment and hanging component 3 can automatically carry out insurance protection. This structure is more suitable for long - distance lifting and conveying work, can improve the safety of dealing with risks when the rubber conveyor belt 101 breaks. The anti - detachment and hanging component 3 can automatically hang on the idler to limit the rubber conveyor belt 101, prevent the broken part of the rubber conveyor belt 101 from continuously falling, and avoid the materials and the rubber conveyor belt 101 from injuring the staff. Especially for the breakage of a long - distance rubber conveyor belt 101, as the kinetic energy increases continuously after its breakage, it will cause major production accidents. At the same time, the one - way limiting component 4 can lock and limit after the anti - detachment and hanging component 3 automatically hangs on the idler, preventing the hook 304 from slipping when cleaning the impurities on the rubber conveyor belt 101 and repairing the rubber conveyor belt 101 later. When the rubber conveyor belt 101 breaks, the broken part of the rubber conveyor belt 101 will fall, driving the hook 304 to fall together and slide down on the idler. At this time, the hook 304 will hang on the idler, and the one - way limiting block 401 can limit the idler to improve safety.

[0024] Embodiment 2. On the basis of Embodiment 1, the segmented detection member 5 includes: a detection rubber sleeve 501, a fixing block 502, and a detection steel wire 503. The detection rubber sleeve 501 is fixedly sleeved outside the rubber conveyor belt 101; a circle of fixing blocks 502 is fixedly installed inside the detection rubber sleeve 501; the tail ends of the detection steel wires 503 are respectively fixedly installed on a circle of fixing blocks 502, and the detection steel wires 503 are located inside the detection rubber sleeve 501; the detection rubber sleeve 501 is of a soft structure; the segmented detection member 5 further includes: a counterweight slip ring 5031, a front slip ring 504, and a movable contact post 505. The counterweight slip rings 5031 are respectively fixedly installed on a circle of detection steel wires 503; a circle of front slip rings 504 is fixedly sleeved inside the detection rubber sleeve 501; the front ends of a circle of detection steel wires 503 are respectively fixedly installed with movable contact posts 505; the counterweight slip ring 5031 is of an iron metal structure; the segmented detection member 5 further includes: a tension spring 5051 and a rear slip ring 506. The front end of the movable contact post 505 is fixedly installed with a tension spring 5051, and the front end of the tension spring 5051 is fixedly installed on the fixing block 502 on its front side; the tension spring 5051 is used to pull the movable contact post 505; the rear slip ring 506 is fixedly sleeved inside the detection rubber sleeve 501; the movable contact post 505 is located between the front slip ring 504 and the rear slip ring 506; the rear slip ring 506 is aligned with the counterweight slip ring 5031; the front slip ring 504, the rear slip ring 506, the movable contact post 505, and the indicator light 1011 are connected in series to the power supply; the indicator light 1011, the counterweight slip ring 5031, and the rear slip ring 506 are connected in series to the power supply; the tension spring 5051 is a plastic insulated spring. This structure can use the segmented detection member 5 to detect the elongation of the rubber conveyor belt 101 in real time, avoiding situations such as the rubber conveyor belt 101 having an unqualified tension due to aging and other factors, resulting in slipping and affecting safety. At the same time, this structure can use the segmented detection member 5 to check the elongation of each area of the rubber conveyor belt 101 in segments, making it more convenient for the staff to quickly locate the elongation area and conduct subsequent detailed inspections. This structure can facilitate understanding the elongation of the rubber conveyor belt 101 in advance, timely repair and replacement, reducing the risk of the rubber conveyor belt 101 breaking directly. This structure can detect in real time, accurately and efficiently. Using the counterweight slip ring 5031 can follow the swing when the rubber conveyor belt 101 is driven and conveyed. Once the inertial force of the swing exceeds the standard, the rubber conveyor belt 101 will shake the counterweight slip ring 5031 to detect the state of the counterweight slip ring 5031, facilitating the staff to adjust the rubber conveyor belt 101 in time and reducing the safety hazards brought by the shaking of the rubber conveyor belt 101. Once the telescopic amplitude of the rubber conveyor belt 101 exceeds the standard, the indicator light 1011 can alarm at this time, indicating that there is a safety hazard in this part of the rubber conveyor belt 101 and it needs to be checked.

[0025] Working principle of this embodiment: First, the rubber conveyor belt 101 needs to be installed on the conveyor rollers. At this time, manual operation can be used for thermosetting bonding. After the rubber conveyor belt 101 and the aramid fabric layer 102 are thermosetting bonded with their heads and tails in contact, the opposite two joint embedding blocks 201 are in contact. At this time, the conveyor rollers can be tensioned. Then, the staff can use a multimeter to detect whether there is an open circuit problem for the two test guide wires 202 on the same side. Once there is an open circuit, it means that the two joint embedding blocks 201 are no longer in contact, that is, cracks appear. The staff can observe regularly. As the rubber conveyor belt 101 is conveyed and moves, the rubber conveyor belt 101 can drive the conductive wire 1031. The counterweight ball 104 at the lower part can be in contact with the ground and automatically conduct grounding work. As the rubber conveyor belt 101 is conveyed and moves, when the rubber conveyor belt 101 breaks, the broken part of the rubber conveyor belt 101 will fall, driving the hook 304 to fall back together and slide down on the idler. Due to the opening direction setting of the hook 304 at this time, it will naturally hang on the lower idler under its own weight. When the hook 304 hangs on the idler, the inclined plane one-way limiting block 401 will not get stuck and can be squeezed to retract inside the one-way limiting block 401. On the contrary, the one-way limiting block 401 can be used to limit the idler and prevent the hook 304 from slipping off the idler. It is necessary to manually press the one-way limiting block 401 to remove the hook 304. When the rubber conveyor belt 101 shakes, when the counterweight power connection ring 5031 shakes, the tension spring 5051 is elastically pulled. Once the shaking amplitude exceeds the standard, the counterweight power connection ring 5031 fits the rear power connection ring 506, and the indicator light 1011 can light up for alarm. At the same time, once the rubber conveyor belt 101 shrinks or elongates, in the flat section area of the rubber conveyor belt 101, as long as the telescopic amplitude exceeds the standard, under the elastic pulling and adaptation of the tension spring 5051, the moving power connection column 505 can be pulled to adapt to the telescoping of the rubber conveyor belt 101. When the moving power connection column 505 fits the front power connection ring 504 or the rear power connection ring 506, the indicator light 1011 can give an alarm prompt, which is convenient for workers to find in time.
