The specific embodiment
below preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be those skilled in the art will recognize that, protection scope of the present invention is made to more explicit defining.
shown in Fig. 1, the present invention is a kind of overload protection device for chain delivery machanism 1, and this chain delivery machanism 1 is used in cleaning machine, and load-transfer device 11 used is guipure.Direction shown in the arrow of Fig. 1 middle and upper part is the transmission direction of load-transfer device 11, and shown in the arrow at right part the second sprocket wheel 21 places, direction is the rotation direction of the second sprocket wheel 21.Described chain delivery machanism comprises load-transfer device 11, a plurality of the first sprocket wheels 12 that are connected by described load-transfer device 11, and load-transfer device 11 is driven by least one drive sprocket, and drive sprocket drives rotation by the motor of chain delivery machanism.When load-transfer device 11 transships because of reasons such as jams; load-transfer device 11 is tending towards running slowly owing to being subject to resistance or friction force; but because chain delivery machanism is still in running state; drive sprocket still drives and orders about load-transfer device 11 operations with normal speed; this just makes the tension force of load-transfer device 11 be tending towards increasing; if in time chain delivery machanism is not shut down, the tension force of load-transfer device 11 further increases until load-transfer device 11 is pulled bad even breaks.
in conjunction with shown in Fig. 1 to Fig. 3, described overload protection device 2 comprises frame, by motor, driven the second sprocket wheel 21 of rotation, the detection with pilled-in selvedge and slack list is with 22, be arranged at actively the detection wheel 20 in frame, be fixedly installed on the first sensor 28 in frame, described detection drives the pilled-in selvedge and the second sprocket wheel 21 that turn round and detect with 22 to have a contact point A with 22 by the second sprocket wheel 21, described the first sprocket wheel 12 of one of them is connected with the second sprocket wheel 21 with 22 by detection and this first sprocket wheel 12 has a contact point B with the pilled-in selvedge detecting with 22, described detection wheel 20 rollably contacts and has a contact point C with detecting with 22 pilled-in selvedge phase, when described load-transfer device 11 normal operation, as shown in phantom in Figure 1, contact point A, B, C forms a triangle, when described load-transfer device 11 is by jam and tension force while increasing, as shown in solid line in Fig. 1, contact point C is close to the line of contact point A, B, and described first sensor 28 detects and detects wheel 20 and move, and described conveying mechanism is shut down.Described detection wheel 20 is positioned at the outside of detecting with 22, described the second link is positioned at the below of detecting wheel 20, described induction wheel 27 is positioned at the below of detecting wheel 20, swing component 23 is arranged in frame rotationally by a rotating shaft 24, and rotating shaft 24 has certain distance apart from first end and second end of swing component 23.
this overload protection device also comprises that one is arranged at the attaching parts 26 that swing component 23, in described frame has relative first end and the second end rotationally; described swing component 23 has relative first end and the second end; described detection wheel 20 is arranged on the first end of swing component 23 rotationally, and the second end of described swing component 23 is connected in frame actively by a return unit.The first end of described attaching parts 26 is connected in frame rotationally; the second end of described attaching parts 26 is provided with an induction wheel 27 rotationally; described induction wheel 27 rollably contacts all the time mutually with the second end of swing component 23; when described load-transfer device 11 is by jam and tension force while increasing; described induction wheel 27 moves to the induction region place of first sensor 28, and described conveying mechanism is shut down.
fixing one second sensor 29 that is provided with also in described frame; when the tension force of described load-transfer device 11 is too small; contact point C is the line of contact point A, B further away from each other, and described induction wheel 27 moves to the induction region place of the second sensor 29, and described conveying mechanism is shut down.When chain delivery machanism normally moves, induction wheel 27 is over against a zero position, and first sensor 28 and the second sensor 29 lay respectively at the both sides of zero position.The maximum tension that first sensor 28 should can bear according to load-transfer device 11 apart from the distance of zero position is set, when first sensor 28, by detecting induction wheel 27, sense to detect and take turns 20 while moving right guaranteeing, the tension force of load-transfer device 11 is still in tolerance range and unlikely fracture.The second sensor 29 should can drive the minimum tension of transported material operation to set according to load-transfer device 11 apart from the distance of zero position, at the second sensor 29, can sense and detect before wheel 20 is moved to the left guaranteeing, load-transfer device 11 can both have enough tension force to transport transported material.When load-transfer device 11 tension force increase; detecting wheel 20 drives the second end of swing arm to swing left; induction wheel 27 is moved to the left thereupon; while entering into the monitored area of first sensor 28 to induction wheel 27; first sensor 28 detects signal, and then sends signal and shut down by control conveying mechanisms such as controllers.
described the first return unit is spring, specific in the present embodiment for extension spring 25.Extension spring 25 is to reset in order to make to detect wheel 20 on the one hand, on the other hand the sensitivity of adjustable detection.
described detection is with 22 for chain, and described detection wheel 20 is sprocket wheel, and described detection wheel 20 is meshed with the pilled-in selvedge detecting with 22.
when the jammed moment of load-transfer device 11 of chain delivery machanism, because the drive sprocket of load-transfer device 11 is still driven and carried out high-speed operation by the motor of conveying mechanism, make the instantaneous tension force of load-transfer device 11 increase, the first sprocket wheel 12 of load-transfer device 11 slows down or stall, and the second sprocket wheel 21 still drives normal operation by the motor of overload protection device, make continuous increase of tension force detecting with 22 pilled-in selvedges that detection is constantly tightened with 22 pilled-in selvedge, be contact point A, distance between C and contact point C, distance sum between B constantly reduces, and then promotion detection wheel 20 moves, when whether first sensor 28 arrives its monitored area and sense while detecting wheel 20 mobile by detecting induction wheel 27, send control signal, and then control chain delivery machanism and shut down, the tension force of real time on-line monitoring load-transfer device 11, avoid load-transfer device 11 because of former thereby lasting increases of tension force such as jams, prevent that load-transfer device 11 from being pulled bad or breaking.
above-described embodiment, for explanation technical conceive of the present invention and feature, is only a kind of preferred embodiment, and its object is that person skilled in the art can understand content of the present invention and implement according to this, can not limit protection scope of the present invention with this.Equivalent transformation or modification that all Spirit Essences according to the present invention are done, within all should being encompassed in protection scope of the present invention.
