Description
Technical field
The utility model relates to a kind of pick-up unit, particularly relates to a kind of device for detecting belt tearing that detects in the backhaul of belt conveyer structure.
Background technology
In the coal shipment, belt feeder is an important device of bearing the coal transhipment.But because the various impurity that often mixing in the coal, and these impurity tend to specific position (mainly be the discharging point at chute near) belt be caused damage.Gently then can cause the fracture of belt torn edges, Steel cord, heavy then can cause the belt transverse breakage, or even grow the longitudinal tear of distance.
Simultaneously, the impurity of removing fully in the coal also is almost out of the question, in a single day so tear accident, moment can in time detect and can stop the drive motor operation and just become extremely important.Tear loss because so just can control the minimum of belt, shorten repair time simultaneously and reduce rehabilitation expense, to ensure finishing smoothly of production operation task.
Cardinal principle of tearing sniffer shown in Figure 1 is when belt 100 surfaces have foreign material to penetrate and follow belt 100 running, can touch the wire rope 200 shown in the figure, wire rope 200 and then can spur the two ends microswitch, thus can detect the generation of tearing.This kind pick-up unit exists that misoperation is more, the scene resets difficulty, shortcoming such as damage very easily.
The another kind of existing sniffer of tearing mainly is made up of conductive silicon rubber and detector switch, and cardinal principle is that detector switch is made action, sends and tears signal when foreign matter touching conductive silicon rubber bar.This kind apparatus cost costliness, and very easily damage, can only change and can not repair simultaneously, thereby maintenance cost is high.
But according to the industry data statistics, it is varied to find that belt is torn the later form of expression, is mainly following several phenomenon: stripping, fracture of wire, longitudinal tear, transverse breakage, stacked etc.And existing two kinds of pick-up units just detect at tearing of the generation of the ad-hoc location particular condition under, the multiple form of expression after can not containing belt fully and tearing.Therefore, existing device for detecting belt tearing can not be finished fully in good time detecting the belt tearing fault.
The utility model content
The purpose of this utility model is, overcomes the defective of above-mentioned prior art and a kind of device for detecting belt tearing that can realize in good time detection and carry out hierarchical detection according to the coal breakage amount is provided.
For achieving the above object, the utility model is taked following design proposal:
A kind of device for detecting belt tearing, belt is arranged on the carrying roller of support body support, on the return belt of belt production line, be provided with a plurality of backhaul coal breakages and tear testing agency, described backhaul coal breakage is torn testing agency and is comprised the gantry pillars that links to each other with support body, described gantry pillars is provided with the axis of swing that flexibly connects with gantry pillars, transfer roller links to each other with described axis of swing by hanger, and is provided with in the end of described axis of swing and swings the swing detection sheet that matches near switch.
Preferably, be provided with rotation near switch on described hanger, described rotation matches near the rotation detection lug of switch with the setting of transfer roller roller end.The surface of described transfer roller is made of the material of big friction factor.
Preferably, described swing links to each other with Programmable Logic Controller (PLC) near switch near switch and/or described rotation.Described hanger is provided with length adjustment device.
The utility model has the advantages that: because the utility model can be provided with belt feeder operation any backward position along the line, so, by the utility model being set, can effectively, in time find the belt tearing phenomenon in many places.In addition, the utility model has designed to rotate and has detected and the detecting structure of swing detection two-stage, and testing result in time can be fed back among the PLC, so, have more that fault alarm is clear, fault is found at the scene that is easy in time and fix a breakdown.

Embodiment
Referring to Fig. 2～Fig. 4, the preferred embodiment of a kind of device for detecting belt tearing of the utility model shown in it, belt 1 is arranged on the carrying roller 21 of support body 2 supports, on the return belt 11 of belt production line, be provided with a plurality of backhaul coal breakages and tear testing agency 30, described backhaul coal breakage is torn testing agency 30 and is comprised the gantry pillars 31 that links to each other with support body 2, in the present embodiment, described gantry pillars 31 has two, lays respectively at the both sides of testing agency 30.As shown in Figure 3, described gantry pillars 31 can be fit to the position and be connected with the many places on the support body 2, particular location can be determined according to the structure of belt production line, described gantry pillars 31 is provided with the axis of swing 32 that flexibly connects with gantry pillars 31, in the present embodiment, the described axis of swing 32 adaptive grooves that are provided with on the described gantry pillars 31 that are arranged in, transfer roller 33 links to each other with described axis of swing 32 by hanger 34, and is provided with in the end of described axis of swing 32 and swings the swing detection sheet 41 that matches near switch 4.Preferably, be provided with rotation near switch 5 on described hanger 34, described rotation matches with the rotation detection lug 51 that transfer roller rotating shaft 35 ends are provided with near switch 5.In the present embodiment, the surface of described transfer roller 33 is made of the material of big friction factor, for example rubber, nylon etc.And described swing links to each other with PLC near switch 5 near switch 4 and/or described rotation.Preferably, all link to each other with 5 near switch 4 with PLC.
In actual use, can a plurality of backhaul coal breakages of the present utility model be torn the even at a certain distance or dispersed placement of testing agency 30, and be arranged on the top of return belt 11 along the belt production line.Described hanger 34 is provided with length adjustment device, and by regulating this length adjustment device, making has a less clearance between nylon transfer roller 33 and the return belt 11.By adjusting the size in this gap, can regulate detection sensitivity of the present utility model on the whole.
When tearing generation, if if the backhaul coal breakage is more, when it passes through from below of the present utility model, will directly push nylon transfer roller 33 and hanger 34 thereof, make its opposite direction swing along backhaul, axis of swing 32 also drives swing detection sheet 41 at this moment and turns an angle.Swing is used for the angle of wobble detection near switch 4, and just can produce alerting signal this moment.
If coal breakage is less when tearing, when then coal breakage passes through below device of the present utility model, because the gap between nylon transfer roller 33 and the return belt 11 is less, coal will produce friction with nylon transfer roller 33.Under the friction force effect, constantly drive nylon transfer roller 33 and be rotated.Rotating detection lug 51 will make rotation constantly produce pulse near switch 5.And the utility model preferably all links to each other with PLC with 5 near switch 4, so this moment, the PLC program begins counting, produces alerting signal when counting surpasses setting value.
Obviously, those of ordinary skill in the art can constitute various types of pick-up units with a kind of device for detecting belt tearing of the present utility model.
The foregoing description is only for the usefulness that the utility model is described; and be not to be to restriction of the present utility model; the those of ordinary skill in relevant technologies field; under the situation that does not break away from the utility model scope; can also make various variations and modification; therefore all technical schemes that are equal to also should belong to category of the present utility model, and scope of patent protection of the present utility model should be limited by each claim.
