Abstract
The invention relates to a head deviation preventing device used on conveying equipment. The head deviation preventing device comprises a shell and a pressure plate obliquely fixed in the shell; the left middle part of the pressure plate is provided with a bolt hole, a bolt and a nut are arranged in the bolt hole, the lower part of the nut is connected with a spring, and the spring is connected with the shell through a cap nut; a limit switch supporting plate with a sensor is arranged under the pressure plate, and the limit switch supporting plate is fixed on the shell; the right side of the pressure plate is fixed on the shell through a home-made bolt and a fixing nut; and the limit switch supporting plate is connected with the shell by a cotter pin. The head deviation preventing device has the advantages that the device can quickly alarm and timely adjust a conveyer belt when the belt is deviated so as to prevent the conveyer belt from tension fracture due to deviation.
Description
Technical field:
The present invention relates to a kind of head deviation preventing device, be 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 invention provides a kind of head deviation preventing device that is used for the alarm belt deviation.
The technical solution adopted for the present invention to solve the technical problems 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.
In advantage of the present invention be: 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 invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the birds-eye view of Fig. 1.
Structural representation when Fig. 3 uses for the present invention.
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 invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment did.
