Abstract
The utility model discloses a kind of belt deflection prior-warning device, it comprises the many groups strut bar being disposed on load-transfer device frame both sides respectively, described strut bar is formed by the cross bar at montant and top, the cross bar being positioned at load-transfer device dual-side top position place is respectively arranged with chain, bottom described chain, be provided with tilt switch, strut bar is provided with warning device and time relay.The utility model advantage is that structure is simple, with low cost, convenient to use.Just can send after the time delay of offset signals elapsed time relay, the operating swing of load-transfer device can be avoided and send out offset signals by mistake, improving the accuracy of early warning; For to link between tilt switch with strut bar, wearing and tearing can not be caused to load-transfer device; Tilt switch can light the alarm lamp of warning device while sending offset signals, directly points out which section belt deflection of attendant and to that side sideslip; Tilt switch and connection box are integral packaging, longer service life, and reliability is higher.
Description
Technical field
The utility model relates to technical field of electric equipment, especially relates to a kind of belt deflection prior-warning device.
Background technology
Band conveyor widespread use and the industry such as mine, electric power are used for carrying out the conveying of material.Due to reasons such as aging, the wearing and tearing after the defect of frame manufacturing, in installation process or equipment long-time running.Load-transfer device can be caused to be in operation the situation of sideslip occurs.Simultaneously also may cause belt deflection due to the reason of material skewness on the conveyor belt.Not only can cause the wearing and tearing of belt until scrapping of whole piece belt not in time if find after belt deflection, cause huge property damage; Material can be caused on the way to shed in a large number after belt deviation simultaneously, pollute production environment, increase the work capacity of cleaning.The following problem of existing deviation switch ubiquity and affect result of use: existing deviation switch is without delay function, and switch there will be erroneous judgement and shuts down when temporary sideslip occurs load-transfer device, causes conveyer frequent start-stop, reduces work efficiency; Existing deviation switch is all rely on the action of internal mechanical formula travel switch to send offset signals, and the mechanical life of travel switch is limited, there will be the situation of tripping or malfunction after long-time running; Existing deviation switch touches pressure roller by after belt deviation, pressure roller presses travel switch again and sends offset signals, pressure roller is equipped with bearing, with belt contacts after can start under friction force effect rotate with anti-wear load-transfer device, but the working environment of conveyer is generally relatively severe in above-mentioned industry, dust is comparatively large, because of the erosion of dust or moisture content, bite will occur through rear bearing after a while, cause pressure roller and belt direct friction, thus damage load-transfer device.Meanwhile, after existing deviation switch action, attendant cannot judge to be that section of belt deviation and belt is to that side sideslip immediately, cannot rectify a deviation to belt in time.
Summary of the invention
The utility model object is the belt deflection prior-warning device providing a kind of delayed alarm.
For achieving the above object, the utility model can take following technical proposals:
Belt deflection prior-warning device described in the utility model, it comprises the many groups strut bar being disposed on load-transfer device frame both sides respectively, described strut bar is formed by the cross bar at montant and top, the cross bar being positioned at load-transfer device dual-side top position place is respectively arranged with chain, bottom described chain, be provided with tilt switch, strut bar is provided with warning device and time relay.
Bottom described load-transfer device frame, be provided with connection box, described time relay is placed in described connection box.
The utility model advantage is that structure is simple, with low cost, convenient to use.Just can send after the time delay of offset signals elapsed time relay, delay time is adjustable between 0-30 second, can avoid the operating swing of load-transfer device and send out an offset signals by mistake, improving the accuracy of early warning; Tilt switch, by self gravitation work, gets final product action when its offset vertical direction is more than 15 degree; For to link between tilt switch with strut bar, directly hang installation, wearing and tearing can not be caused to load-transfer device; Tilt switch can light the alarm lamp of warning device while sending offset signals, directly points out which section belt deflection of attendant and to that side sideslip; Tilt switch and connection box are integral packaging, and there is not corrosion and wear problem, longer service life, reliability is higher.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Working state figure when Fig. 2 is sideslip on the left of load-transfer device.
Detailed description of the invention
As shown in Figure 1, 2, belt deflection prior-warning device described in the utility model, it comprises the many groups strut bar being disposed on load-transfer device frame 1 both sides respectively, described strut bar is formed by the cross bar 3 at montant 2 and top, the cross bar 3 being positioned at load-transfer device 4 dual-side top position place is respectively arranged with chain 5, bottom described chain 5, be provided with tilt switch 6, strut bar is provided with warning device 7 and time relay 8; Bottom load-transfer device frame 1, be provided with connection box 9, described time relay 8 is placed in described connection box 9.
During use, when load-transfer device 4 normally runs, be suspended on tilt switch 6 on the cross bar 3 of strut bar in vertical state (as shown in Figure 1).When there is skew to side during load-transfer device 4 runs and departure distance is larger, the edge of load-transfer device 4 touches tilt switch 6(as shown in Figure 2), tilt switch 6 will run-off the straight under the promotion of load-transfer device 4, load-transfer device 4 sideslip is more serious, then the angle of tilt switch 6 inclination is larger, when angle is more than 15 degree, the normal opened contact of tilt switch 6 closes, run up time relay 8, if load-transfer device 4 is temporary sideslip just, so before setting time, tilt switch 6 will reply normal condition, or in small angle range slight oscillatory, this timer can not send out offset signals by mistake, can ensure that conveyer normally runs, if there is the situation of continuation sideslip, after having arrived setting time, a pair open contact of time relay 8 closes, and lights the warning device 7 on strut bar, and another of time relay 8 simultaneously closes open contact, sends offset signals.This offset signals can be sent to central station of floating dock by cable and send warning; or directly sending conveyer control box to acts on shutdown; now attendant can directly judge that according to the warning device 7 lighted which section load-transfer device 4 sideslip occurs, to which side offsets, thus takes suitable satisfactory after correcting in time.
