After being put into normal operation, the effective protection of the detection device to the rubber belt can obviously be seen. The utility model can excellently detect the tearing indication of the rubber belt, so as to remove without delay, thereby preventing the rubber belt from being torn.
Description
Technical field
The utility model belongs to the loading-unload machine protective device, particularly a kind of gig adhesive tape anti-tear device.
Background technology
A master tape and a cover tape are housed on the gig.Master tape is born load, and the whole piece adhesive tape is made by double-deck core and rubber, and structure is tough and tensile.The effect of cover tape is parcel and clamping grain, so it has only both sides to contain core, and the centre is made by elastic force cloth and rubber, and intensity is relatively poor.Clip in the process of grain lifting at master tape and cover tape, as being mixed with hard foreign material in the grain, such as the ironware of different shape, the chute of adhesive tape goes wrong, and cover tape is easy to be damaged.The running velocity of adhesive tape is very fast again, and per second can reach 5 meters, as untimely shutdown; a bit little damage is with very fast expansion; light then the openning that can make adhesive tape different shape occur, vary in size, heavy then can tear adhesive tape in two, cause one long 160 meters, be worth nearly 100,000 yuan adhesive tape and scrap.In a single day this phenomenon occurs, and this gig place flow process line is all paralysed.Tissue repairing immediately at least a few hours, several days at most, just can return to normal production.In these several years, this phenomenon occurs time and again, and the human and material resources that spent, financial resources, time are difficult to calculate, and loses huge.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of gig adhesive tape anti-tear device is provided.The sign of monitoring adhesive tape before tearing in time handled, and prevents that adhesive tape from tearing.
The technical solution of the utility model is:
Observe repeatedly through the scene, find the surface to be changed when firm the coming to harm of adhesive tape, when its process afterbody bending roller, will " projection ".According to this phenomenon; if can be at the positive design and installation one cover detecting device of afterbody bending roller; when the segment of tape that comes to harm runs to the afterbody bending roller; " projection " part can make its action by touch detection device; thereby cause gig warning shutdown; ascertain the reason then and solve, will eliminate fault in bud.
Therefore design a kind of gig adhesive tape anti-tear device, it is characterized in that: a cover detecting device is housed in gig afterbody bending roller front, detecting device has a framework, the front end of framework abuts against on the tape surface in gig afterbody bending roller front, back-end framework is connected on the gimbal axis, the gimbal axis two ends are connected on two fixing on chassis bearing seats, the centre of framework is connected with the intermediate beam perpendicular to the bending roller axle, intermediate beam and framework are connected as a single entity, the intermediate beam below has one to be fixed on the chassis and the back-up block that separates with intermediate beam near near the gimbal axis, back-up block is supporting intermediate beam, and support with this and to make framework integral body be in horizontality, one extension rod is arranged on the framework, extension rod is to the extension rod that extends away from the bending roller direction from the gimbal axis of framework, the below of extension rod end is provided with limit switch, the cable connection control circuit of limit switch.
Characteristics of the present utility model and effect
After the normal operation of detecting device input, we can see obviously that through long-term observation it is effectively to the protection of adhesive tape.Adhesive tape is anti-tears warning as having taken place in one-stop operation, checks that reason is the adhesive tape interface drum that come unglued.Facts have proved that it is successful installing this cover detecting device additional.Monitor adhesive tape well and will tear sign, in time get rid of, prevented that adhesive tape from tearing generation.

The specific embodiment
A kind of gig adhesive tape anti-tear device as shown in Figure 1, one cover detecting device is housed in gig afterbody bending roller 2 fronts, detecting device has a framework 3, the front end of framework abuts against on adhesive tape 1 surface in gig afterbody bending roller front, back-end framework is connected on the gimbal axis 5, the gimbal axis two ends are connected two fixing on chassis bearing seats 4, on 17, the centre of framework is connected with the intermediate beam 12 perpendicular to the bending roller axle, intermediate beam and framework are connected as a single entity, there is a back-up block 7 that is fixed on the chassis and separates with intermediate beam the intermediate beam below near near the gimbal axis, back-up block is supporting intermediate beam, and support with this and to make framework integral body be in horizontality, one extension rod 8 is arranged on the framework, extension rod is to the extension rod that extends away from the bending roller direction from the gimbal axis of framework, the below of extension rod end is provided with limit switch 9, the cable connection control circuit of limit switch.
Design and manufacture has also been installed this detecting device on gig.As shown in Figure 1.We are welding one extension rod on axle also, and electric () limit switch LX5 is being installed on the chassis, under the extension rod, and it joins by original joint box JBC1356 on two core cable 10, two logical connection boxes 11 and the equipment.
The principle of this covering device is as follows: (referring to machine drawing 1, electric diagram 2) adhesive tape under normal circumstances, during the gig operation, this covering device is static.Coming to harm as the adhesive tape in running condition changes the surface, and tape surface " projection " part will be lifted framework, thereby makes the axle motion, drive collision block motion and touching limit switch LX5, its normally closed point is opened, and electric signal is sent in the switch board by cable, makes the BSR dead electricity.Adhesive tape injury section is through behind the framework, and framework still falls back on the back-up block on chassis, though the normally closed point of LX5 closure once more, the BSR coil can not get yet.The normally closed point of BSR is connected LT13, and switch board shows the adhesive tape fault alarm.BSR makes the DTR dead electricity again normal battle, and DTR makes the DTT dead electricity again, and gig just stops with this program.Simultaneously, DTR makes the HR dead electricity, and the control personnel take measures in the notice.The adhesive tape fault alarm is the same with other fault alarm of gig, must be by the knob that resets on switch board surface, and behind the affirmation trouble removal, the cancellation that can reset is reported to the police.
This covering device is debugged after all installing.The starting gig, treat normal operation after, we put a little grains on the backhaul band, the sight with the simulation adhesive tape when damaged.When the adhesive tape band grain and walked around the afterbody bending roller, the convex closure that adhesive tape is heaved lifted framework at once, and collision block has been touched limit switch at once, the switch board display alarm, and gig has also stopped getting off according to program.We have threshed several similar tests again, and are all very successful.Thereby the adjustment of sensitivity is to reach by adjusting the distance that the position of chassis on steel structure change framework and adhesive tape.
