Abstract
The utility model relates to a off tracking switch for transmission band, including edger roll, vertical roll axle, rocking arm, the formula angle detection ware that resets and the formula angle detection ware axle that resets. The vertical roll shaft is welded at one end of the rotating arm in an inclined mode, the other end of the rotating arm is welded at one end of the reset type angle detector shaft, and the other end of the detector shaft is hinged to the reset type angle detector. The vertical roll is sleeved on the vertical roll shaft and rotates around the vertical roll shaft. The utility model discloses a deviation switch has increased the rocking arm on prior art basis, when using the installation, make the bottom surface and the angle beta of belt traffic direction slope of the formula that resets angle detector again, consequently can make the edger roll when receiving the extrusion of deviation belt, not only can self rotate, can also turn round in a plane that becomes the beta angle with the belt plane simultaneously, when the breach appears in the belt edge, the edger roll can follow belt deviation direction and belt face vertical direction and take place the displacement simultaneously, let the belt breach open, protect the deviation switch not impaired promptly.
Description
Technical field
The utility model relates to a kind of sideslip switch that is used for transport tape, belongs to equipment technology field of transport.
Background technology
In existing transportation device; in order to the sideslip switch that the conveyer belt sideslip is given the alarm; its structure as shown in Figure 1; its principle of work is; when belt deviation; edger roll 1 is subjected to along the effect of the friction force of belt direction of travel and self rotates; edger roll and edger roll axle are rotated around the axle 3 of homing position type angle detector again by the effect of belt deviation power simultaneously; by the homing position type detector; the angular dimension that detection turns over; with reaction belt deviation degree, the angle that restorer can be provided with the early warning anglec of rotation and belt feeder is shut down.Convert above-mentioned two angle positions to electric signal, be used to control the operation of belt feeder.The shortcoming of above-mentioned prior art is that edger roll is subjected to along the effect of the friction force of belt direction of travel, can only rotation, when belt edge breach etc. occurs and damages, the edger roll of sideslip switch and axle are subjected to the effect of the power of belt direction of travel, and edger roll and edger roll axle do not have degree of freedom on the direction of this power, thereby can not rotate, cause the sideslip switch to damage easily, even cause belt tearing.
Summary of the invention
The purpose of this utility model is a kind of sideslip switch that is used for transport tape of design, changes the structure of existing sideslip switch, and the sideslip switch can in time be reported to the police when sideslip appears in belt, can guarantee that again sideslip switch and belt are not damaged.
The utility model design-calculated is used for the sideslip switch of transport tape, comprise edger roll, edger roll axle, pivoted arm, homing position type angle detector and homing position type angle detector axle, described edger roll axle tilts to be welded in an end of pivoted arm, the other end of pivoted arm is welded in an end of homing position type angle detector axle, and the other end of detector axle and homing position type angle detector are hinged; Described edger roll is enclosed within on the edger roll axle, rotates around the edger roll axle.
The utility model design-calculated is used for the sideslip switch of transport tape; between edger roll axle that has the sideslip switch and homing position type angle detector axle, increased pivoted arm; when using installation; make bottom surface and angle beta of belt direction of travel inclination of homing position type angle detector again; therefore can make edger roll when being subjected to the extruding of sideslip belt; not only can self rotate; can also in a plane that becomes the β angle with the belt plane, turn round simultaneously; when breach appears in belt edge; edger roll can be subjected to displacement simultaneously along belt deviation direction and strap surface vertical direction; get out of the way the belt breach, promptly protect the sideslip switch not impaired.
Description of drawings
Fig. 1 is the structural representation of the sideslip switch in the prior art.
Fig. 2 is the utility model design-calculated sideslip construction of switch scheme drawing.
Fig. 3 is the position view of the utility model design-calculated sideslip switch when using installation.
Fig. 4 is the left hand view of Fig. 3.
Among Fig. 1 to Fig. 4, the 1st, edger roll, the 2nd, edger roll axle, the 3rd, homing position type angle detector, the 4th, homing position type angle detector axle, the 5th, pivoted arm, the 6th, belt, the 7th, carrying roller.
The specific embodiment
As shown in Figure 2, the utility model design-calculated is used for the sideslip switch of transport tape, comprises edger roll 1, edger roll axle 2, pivoted arm 5, homing position type angle detector 4 and homing position type angle detector axle 3.Edger roll axle 2 tilts to be welded in an end of pivoted arm 5, and the other end of pivoted arm is welded in an end of homing position type angle detector axle 3, and the other end of detector axle and homing position type angle detector 4 are hinged.Edger roll 1 is enclosed within on the edger roll axle 2, rotates around the edger roll axle.
The utility model design-calculated sideslip switch, when using installation, the sideslip switch places a side of belt, as shown in Figure 3, makes bottom surface and angle beta of belt direction of travel inclination of homing position type angle detector 4 simultaneously, as shown in Figure 4, when belt deviation, edger roll 1 is subjected to along the effect of belt 6 sense of motion power, and self rotates, be subjected to simultaneously the horizontal thrust of belt opposite roller again, make edger roll drive pivoted arm 5 and in the inclined-plane that becomes the β angle with strap surface, rotate around homing position type angle detector axle 3.When the marginal existence breach of belt 6, edger roll can be subjected to displacement simultaneously along belt deviation direction and strap surface vertical direction, gets out of the way the belt breach, promptly protects the sideslip switch not impaired, can not make belt tearing again.
Claims (1)
1, a kind of sideslip switch that is used for transport tape is characterized in that this sideslip switch comprises edger roll, edger roll axle, pivoted arm, homing position type angle detector and homing position type angle detector axle; Described edger roll axle tilts to be welded in an end of pivoted arm, and the other end of pivoted arm is welded in an end of homing position type angle detector axle, and the other end of detector axle and homing position type angle detector are hinged; Described edger roll is enclosed within on the edger roll axle, rotates around the edger roll axle.
