Abstract
The utility model relates to a head off-tracking prevention device, which is used on conveying equipment. The head off-tracking prevention device comprises a case and a press plate, wherein the press plate is obliquely fixed in the case, the left middle part of the press plate is provided with a bolt hole, a screw bolt and a screw nut are arranged in the bolt hole, the lower part of the screw nut is connected with a spring, the spring is connected with the case through a cover-shaped screw nut, a position limiting switch support plate with a sensor is arranged under the press plate, the position limiting switch support plate is fixed on the case, the right side of the press plate is fixed on the case through a self made screw stud bolt and a fixing screw nut, the position limiting switch support plate and the case are connected through an opening pin. The utility model has the advantages that the warning can be fast carried out when a belt is in the off tracking state, a conveying belt can be regulated in time, and the pulling fracture of the conveying belt caused by off tracking can be avoided.
Description
Technical field:
The utility model relates to a kind of head deviation preventing device, is used for load transfer device.
Background technology:
Load-transfer device band in the load transfer device of prior art is easy to sideslip, if untimely discovery will cause load-transfer device to skid even ruptures.
Summary of the invention:
In order to solve the problems of the technologies described above, the utility model provides a kind of head deviation preventing device that is used for the alarm belt deviation.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of head deviation preventing device, comprise housing and tilt to be fixed on the interior pressing plate of housing, a bolt hole is offered at middle part, a described pressing plate left side, described bolt hole is equipped with screw bolt and nut, described nut bottom is connected with spring, described spring links to each other with housing by acorn nut, and described pressing plate below is provided with a limit switch stay bearing plate that has a sensor, and described limit switch stay bearing plate is fixed on the housing.
Further: described pressing plate right side is fixed on the housing by self-control double-screw bolt and captive nut.
Further: described limit switch stay bearing plate is connected by spring cotter with housing.
The utility model has the advantages that: can very fast reporting to the police when belt deviation, in time adjust load-transfer device, prevent to break because of sideslip causes load-transfer device.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the birds-eye view of Fig. 1.
Structural representation when Fig. 3 uses for the utility model.
Among the figure: 1, housing; 2, pressing plate; 3, bolt hole; 4, bolt; 5, nut; 6, spring; 7, acorn nut; 8, limit switch stay bearing plate; 9, self-control double-screw bolt; 10, captive nut; 11, take turns end to end; 12, spring cotter.
The specific embodiment:
A kind of head deviation preventing device shown in Fig. 1～2, it comprises that housing 1 and inclination are fixed on the pressing plate 2 in the housing 1, described pressing plate 2 right sides are fixed on the housing 1 by self-control double-screw bolt 9 and captive nut 10, a bolt hole 3 is offered at middle part, described pressing plate 2 left side, described bolt hole 3 is equipped with bolt 4 and nut 5, described nut 5 bottoms are connected with spring 6, described spring 6 links to each other with housing 1 by acorn nut 7, described pressing plate 2 belows are provided with a limit switch stay bearing plate 8 that has a sensor, and described limit switch stay bearing plate 8 is fixed on the housing 1 by spring cotter 12.
In conjunction with Fig. 3, head deviation preventing device is installed on the load transfer device, as for taking turns 11 both sides end to end, when on the load transfer device during belt deviation, taking turns belt on 11 end to end can depart from and take turns 11 line of centers end to end, move and clash into pressing plate 2 to pressing plate 2 directions, compressing pressing plate 2 is to housing 1 inner moving, when pressing plate 2 strikes the beam certain position, because because connecting bridge is a spring 6 between pressing plate 2 left sides and the housing 1, spring 6 abilities have certain elasticity and toughness, it is difficult for being fractureed, can drive acorn nut 7 moves, to making acorn nut 7 run into limit switch stay bearing plate 7,, send induction by sensor owing to have sensor on the limit switch stay bearing plate 7, signal is spread out of, send the belt deflection alarm.
It below only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
