Description
Technical Field
The utility model relates to the technical field of underground raw coal conveying equipment of a coal mine, in particular to a tearing-proof protection device for a conveying belt of a belt conveyor.
Background
The transportation of the coal mine underground raw coal mainly depends on the transportation of a belt conveyor, the belt tearing accident of the conveyor belt is easily caused after the penetration of a hard iron device and gangue, and the more serious belt tearing accident can be caused if the belt cannot be stopped in time after the belt tearing, so that the production progress is influenced, and the serious economic loss is caused;
the principle of the existing anti-tearing protection of the conveying belt is that after the conveying belt is torn, a belt is separated, raw coal is sprinkled on a coal collector, the coal collector contacts a switch to act, and the belt stops running, but the belt is not separated after being torn in field conditions, but the belt is continuously overlapped under the action of the channeling of a roller frame and the gravity of the raw coal, so that the existing coal collector is difficult to protect belt tearing accidents;
therefore, a new anti-tearing protection device for the conveying belt of the belt conveyor is provided to solve the problems of the device.

the conveying device comprises a rack and a conveying roller, wherein the top of the rack is rotatably connected with the conveying roller through a bearing, and a belt is arranged on the outer side of the conveying roller;
further comprising: and the speed sensor is arranged on one side of the conveying roller and used for detecting the rotating speed of the belt.
Preferably, a hydraulic oil cylinder is installed on the outer side of the frame, the top of the hydraulic oil cylinder is rotatably connected with a cross rod through a bearing, the cross rod is divided into three sections, and the three sections are rotatably connected through the bearing;
the cross rod is arranged between the two conveying rollers, and the cross rod is arranged at the position 5m away from the non-working surface of the belt on the lapping point along the coal flow direction.
Preferably, the end of the conveying roller is provided with an annular step, and one side of the step facing the center of the conveying roller is provided with a slope.
Preferably, the speed sensor is a contact roller sensor, the speed sensor is arranged between the two conveying rollers, and the speed sensor is flush with the end step of the conveying roller.
Preferably, a group of speed sensors are respectively arranged at the lapping points at the two sides of the belt along the coal flow direction by 10-15m, and the speed sensors are provided with a power supply and a control switch matched with the speed sensors.
Compared with the prior art, the utility model has the beneficial effects that:
1. this belt conveyor conveyer belt anti-tear protection device, through being provided with horizontal pole and hydraulic cylinder, when the belt tears, drives the horizontal pole through hydraulic cylinder and rises, and the jacking belt helps reducing the folding condition of belt, does benefit to the maintenance simultaneously.
2. Secondly, this belt conveyor conveyer belt anti-tear protection device through being provided with the transfer roller, and the transfer roller terminal surface is provided with the step, and the step is spacing to the belt, and when the belt off tracking, through the gravity of the self of belt, make the belt slide along the domatic of step, ensures that the belt moves at the central line position of transfer roller.
3. Secondly, this belt conveyor conveyer belt anti-tear protection device through being provided with speedtransmitter, through the marginal installation speedtransmitter at the belt, detects the belt running state, and speedtransmitter stall when the belt tears to the machine can in time be closed.
